| The electronic communications services market in France in the 2nd quarter of 2007 |
| Last update 9th November 2007 |

 To download or print the survey ( pdf)  During the second quarter 2007, electronic communications operator
revenue on the end customer market was €10.5 billion. The intermediate
market (interconnection services and sales on the wholesale market between operators)
represented an additional €2.1 billion.
Excluding related services (terminal sales and rentals, directories,
advertising, hosting and call centre management, etc.), revenue from electronic
communications services on the end customer market was €9.7 billion during
the second quarter 2007, growing 3.2% in one year.
The volume of telephony (fixed and mobile) services traffic
reached 51.1 billion minutes during the second quarter 2007, for 2.4% growth
in one year.
Fixed telephony and Internet
The number of subscriptions to telephone service reached 38.9 million
at the end of the second quarter 2007. Over 20% of telephone subscriptions,
or 8.7 million subscriptions, are now to voice on broadband service, almost
doubling in one year (+3.8 million additional subscriptions), while the
number of "traditional" subscriptions to dial-up access declined slightly to
just over 30 million.
The growth of voice on broadband results primarily from the
substitution for telephone subscriptions to dial-up access. Now, 12% of fixed
lines, or 3.9 million lines in all, no longer have a dial-up subscription
but only an IP subscription, compared with 4% in June 2006. These lines are
either fully unbundled (2.9 million lines had been unbundled at the end
of the second quarter 2007, with +1.7 million in one year) or have wholesale
offers like "naked ADSL".
The rest of the subscriptions to a voice on broadband service
(through partial unbundling or "bitstream" wholesale offers) are added to an
existing telephone subscription which the customer chooses to keep. So, at the
second quarter 2007, 14% of telephone lines support two subscriptions to a telephony
service (a "traditional" subscription to the PSTN and a subscription to a voice
on IP service).
A fraction of the "traditional" telephone subscriptions are
now billed to the end customer by an operator other than France Telecom. Resulting
from wholesale subscription sale offers, they represented 447 000 subscriptions
at the end of the second quarter 2007, compared with 76 000 three months
earlier. Carrier selection, chosen by 5.8 million customers, was down 22.1%
over one year, declining by 1.7 million subscriptions.
Revenue directly attributable to fixed telephony declined 4.9%
in one year. Subscription revenue grew 3.6%, due to the price increase on 1st
July 2006, which more than compensated for the decline in the number of PSTN
subscriptions. On the other hand, telephone call revenue fell 13.2% because
of the sharp decline in the volume of calls made on the PSTN.
Traffic originating on fixed lines remained practically stable.
Volumes of calls originating on IP access continued to rise sharply (+75.4%
over one year during the second quarter 2007) whereas calls made on the PSTN
continued to decline. Voice on broadband represented 30.3% of the traffic originating
on fixed lines during the second quarter 2007. On average, each customer of
VoIP calls 5 hours and 10 minutes per month, 2 hours more than on a "traditional"
phone.
Multiplay packages often include unlimited calling to long-distance
fixed lines and to many destinations around the world, which brings new life
to these two market segments. Close to half of the minutes (46.0%) of calls
made to international destinations are now made from phones with IP access.
The substitution effect is also strong for long-distance calls for which 31.9%
of minutes are made from IP. On the other hand, calls to mobile phones from
IP access phones represent just 11.3% of the fixed-mobile volume.
The number of Internet subscriptions reached 16.1 million
at end June 2007, up 13.8% in one year. High-speed Internet access continues
to grow at a strong annual rate. The number of high-speed accesses rose by 3.2 million
(+28.5% in one year), reaching 14.2 million at the end of the second quarter
2007. Revenue from high speed was €1 billion at the second quarter 2007
(+34.1% over one year). High speed now represents close to 90% of Internet subscriptions
and revenue.
Mobile telephony
Mobile operators attracted 52.6 million customers in France
at the end of the second quarter 2007. Two-thirds of these purchased flat-rate
packages. The growth in the number of mobile telephony customers remained strong
during the second quarter 2007, with a 7.1% increase over one year, and 3.5 million
new customers during this period.
During the second quarter 2007, 154 400 mobile numbers
were ported from one operator to another, or 37.2% more than during the first
quarter 2007, an increase which can probably be attributed to the simplified
procedure put in place on 21st May 2007 for number conservation.
Mobile service revenue reached €4.4 billion during the
second quarter, up 6.3%. The average monthly invoice of mobile operator customers
(€28.00) was down slightly (0.8%) over one year.
Revenue from data services (interpersonal messaging, mobile
Internet access services and multimedia services) represented €627 million
during the second quarter 2007, just under 15% of total revenue from mobile
services. It increased much more strongly than that of mobile calling (18.6%
in one year compared to +4.5%), although it was not enough to offset the decline
in mobile calling revenue with respect to 2006.
Mobile telephony traffic has been slowing since the beginning
of 2007. In one year, growth was +6.6%, whereas this traffic had jumped by about
15% in 2006. This decline is due primarily to mobile operators’ on-net traffic,
which rose by just 5.5% during the second quarter 2007 over the second quarter
2006, whereas it had grown very strongly in recent years.
Interpersonal messaging continues to be very strong with 4.4 billion
messages sent during the second quarter, for a 20.9% increase in one year. On
average, this corresponds to 28 text messages (SMS) sent per customer per month.
Customers with a flat-rate package use this method of communication twice as
much on average as customers with a pre-paid card (33 and 17 SMS sent per customer
per month respectively). This segment generated €398 million during the
second quarter 2007.
Directory Services
The decline in the volume of calls to directory services continued:
35 million calls were made during the second quarter, compared with 41 million
a year earlier, for a 14.5% decline. Revenue from directory services was €42 million,
up 12.8% in one year.
Note: The figures relating to a particular quarter
may be revised from one issue to the next as a result of corrections made by
operators to their reports. Any discrepancies between annual growth figures
expressed as a percentage and the corresponding values are due to rounding. | 1. The communications market in its entirety |
1.1 The end customer market

Revenue from electronic communications services sold by operators on the end
market was €9.7 billion during the second quarter, up 3.2% in one year.
At €4.4 billion during the second quarter, revenue from mobile services
represents over 45% of all revenue from electronic communications services.
It has been increasing at an annual rate of 5% since the beginning of 2006 (+6.3%
during the second quarter 2007).
Revenue from services sold on fixed networks (fixed telephony and Internet)
reached €3.9 billion during the second quarter 2007. Supported by the increase
in Internet revenue, which has seen annual growth rates of over 20% (+27.5%
in one year during the second quarter 2007), revenue from fixed services rose
2.9% in one year. The regular decline in revenue directly attributable to fixed
telephony continued with a 4.9% decrease over one year.

Total "voice" (fixed and mobile telephony) service volumes represented 51 billion
minutes. The 2.4% increase in this traffic over one year is lower than in 2006,
primarily because of the lower growth in the volume of mobile communications.
The slowdown in the growth rate of the volume of calls originating on mobiles
which began in the first quarter of 2007 (+8.6% over one year) was confirmed
in the second quarter (+6.6% over one year). There is a clear break in the trend
of strong growth seen throughout 2006 (around 15%).
However, the growth in the number of interpersonal SMS sent did not slow. During
the second quarter 2007, 4.4 billion SMS were sent by the customers of
mobile operators (up 21.1% over one year).
Voice traffic originating on fixed networks fell 1.4% over one year during
the second quarter, although this volume stabilised overall thanks to the contribution
of the volumes of telephony on IP, as shown by the seasonally adjusted series.
The ebb in dial-up Internet volumes continued at an annual rate of over 30%.



1.2 The intermediate market (interconnection services/wholesale markets)1.2.1 The total marketFixed network operators’ revenue on the intermediate market reached €1.1 billion
and grew 5.5% over one year. This growth was shored up by the development of
wholesale high-speed access services (unbundling, bitstream or equivalent services)
which represented €368 billion during the second quarter, up 24.7% in one
year.
Mobile operators’ revenue from interconnection services (€1.0 billion
in the second quarter) fell 6.1% over one year. This change is due primarily
to the decline in the voice call termination charge (-21% for Orange France
and SFR and -18% for Bouygues on 1st January 2007). On
the other hand, the increase in traffic measured in minutes reached 22.0% over
one year.


Notes:
- Interconnection revenues and traffic volumes are not calculated on the
basis of the same criteria, which makes a comparison between the two indicators
unsuitable for estimating average prices (interconnection revenues include fixed
revenues such as charges for connection links and intercarrier services).
- Interconnection covers all the services provided by one carrier to another
under the terms of an interconnection agreement. In cases of mergers or takeovers,
some of the revenue streams between the telcos disappear, which might account
for decreases in revenues from one quarter to the next.
- Please note that the interconnection figures shown above might be accounted
for twice, particularly in the case of fixed operators.
- Wholesale broadband services include revenues from both LLU and bitstream
or equivalent services.
The growth in the number of unbundled lines continued at a consistently strong
rate. At the end of the second quarter, 4.6 million lines had been unbundled.
Now, close to two-thirds of these lines, or 2.9 million, are fully unbundled.
The number of fully unbundled lines has been rising strongly and increased
by 1.7 billion over one year. At the same time, partial unbundling (1.7 million
at the end of the second quarter) declined by 440 000 lines (-20.4% over
one year).


1.2.2 Incoming international interconnection
___________________________
This market segment is a subset of the overall market (cf. 1.2.1) 1.2.3 Mobile roaming-in services
Note: Roaming-in is a service whereby a French mobile operator carries calls made and received in France by customers of foreign mobile operators. The revenue corresponds to the outpayments made between operators. The ratio of revenue to volume does not correspond to any specific tariff and particularly not to the price billed to the customer.
____________________________ This market segment is a subset of the overall market (cf. 1.2.1) 2.1 Fixed telephony2.1.1 Access, subscriptions and fixed lines 
The number of subscriptions to a telephone services reached 38.9 million
at the end of the second quarter 2007. The growth in the number of subscriptions
(+3.9% over one year) can be explained by the success of broadband telephony
offers.
The decline in the number of subscriptions to dial-up access (30.2 million
at the end of the second quarter 2007) continued at a rate of 600 000 fewer
subscriptions per quarter. In one year, 2.4 million subscriptions were
cancelled.
For the past several months, it has been possible for alternative operators
to bill customers for their telephone subscriptions. This offer concerned 447 000
subscriptions on the retail market at the end of the second quarter 2007 compared
with 76 000 at the end of the previous quarter.
Broadband telephony is booming. The number of subscriptions to telephony services
on IP access (8.7 million at the end of the quarter) rose by 3.8 million
in one year and now represents 22.4% of telephone subscriptions in service.
Some of the IP subscriptions are replacing existing subscriptions to "traditional"
telephone services. This is the case of offers to broadband voice services resulting
from full unbundling and "naked ADSL" offers, which represented 3.9 million
subscriptions at the end of the second quarter 2007.
Another share, still the majority, but which is barely growing, is added to
an existing telephone subscription which is kept by the user. This is the case
of telephone offers resulting from partial unbundling and "bitstream" outside
"naked ADSL". So, 14% of lines (4.7 million) supported two subscriptions
to telephone service at the end of the second quarter 2007.
Note:
- Subscription to telephone on IP service on xDSL lines without PSTN subscription:
A subscription to telephone service on lines where low frequencies are not used
to support voice service (by the incumbent or by an alternative operator). This
is the case of offers to broadband voice services resulting from full unbundling
and "naked ADSL" offers.
- Subscription to telephone on IP service on xDSL lines with PSTN subscription:
A subscription to telephone service on lines where low frequencies are also
used to support voice service, on the PSTN. This is the case of telephone offers
resulting from partial unbundling and "bitstream" outside "naked ADSL".

Further information concerning the IP telephony service
indicators
The terminology used:
The IP telephony service indicators referred to in this issue cover broadband
voice services, regardless of the type of bearer (primarily DSL IP, but
also cable IP) and Internet voice services where the operators are
registered with ARCEP.
ARCEP uses the term "broadband voice services" to refer to
fixed telephony services which use VoIP technology on an Internet access
network with a bandwidth of more than 128 kbit/s and whose quality
is controlled by the operator providing the service, and "Internet
voice services" to mean voice call services using the public Internet
network and whose quality is not controlled by the operator providing
the service.
The Observatory only records VoIP service calls which originate in the
access layer. The indicators do not cover traffic which uses IP protocol
solely in the core network.
Furthermore, the Observatory does not take into account unregistered
operators which offer PC-to-PC Internet voice services. These operators
are not covered by the scope of the survey.
The revenues taken into account:
The Observatory distinguishes between calls originating on IP telephony
services and other voice calls. However, while the volume of VoIP calls
relates to all such traffic on the retail market, the revenues recorded
cover only the billed VoIP traffic (e.g. calls made on top of those
included in a multiplay package).
|
A total of 575 000 numbers were ported between operators during the second
quarter 2007.

Telephony offers based on carrier selection (call-by-call selection or pre-selection),
have been losing ground to telephony on IP offers since early 2006. These offers
lost 1.7 million subscriptions in one year and concerned 5.8 million
customers during the second quarter 2007. The decline in the number of pre-selection
subscriptions has been sharper since the beginning of 2007 (-17.6% over one
year during the second quarter).


Note: The number of call-by-call selection customers only takes into account
active subscriptions, while carrier pre-selection figures only take into account
current subscriptions, net of cancellations.
Access revenue (€1.5 billion) increased 3.6% over the second quarter 2006.
The increase in the price of France Telecom’s monthly phone bill on 1st July 2006
offset the 7.3% decline over one year in the number of subscriptions to analogue
or digital lines.

Note: In addition to the revenues relating to access to the telephone service,
access revenues also include subscriptions to IP telephony and revenues generated
by additional services (such as calling line identification presentation, etc.). 2.1.2 Calls from fixed lines (excluding public payphones and phonecards)Revenue from telephone calls originating on fixed lines fell 13.2% over one
year during the second quarter 2007 and now represents just 42% of fixed telephony
revenues (including public payphones and cards) compared with 46% a year earlier.
This change reflects the change in retail prices on the PSTN (decline in long-distance
calls and calls to mobiles), but also the erosion in the volume of calls made
on the PSTN (16.8% decline over one year in the second quarter), as well as
the substitution movement of IP telephony over the traditional phone (see note
below).

Note: Revenues from VoIP calls only include charges billed by operators
for such calls made on top of those included in a multiplay package. Therefore,
this amount does not include the cost of the multiplay subscription, nor the
charge for connection to a broadband telephone service.
The strong growth in the volumes of IP telephony (+75.4% over one year during
the second quarter (2007) has made it possible to maintain the overall volume
of fixed telephony for the past three years, as shown by the seasonally adjusted
series.
During the second quarter, calls originating on voice on IP services represented
30.3% of the total volume of telephone calls originating on fixed lines. This
proportion was just 17.1% a year earlier.
This success can likely be explained by a growing number of unlimited call
offers included in multiplay packages for long-distance calls to fixed phones
and to some international destinations.
With 20.8 billion minutes during the second quarter 2007, long-distance
calls between fixed phones represented over 82% of the total volume of calls
originating on fixed networks. Close to one-third (31.9%) of calls are now made
on IP compared with 18.5% a year ago.
Traffic to international destinations increased 31.4% over one year during
the second quarter, thanks to the very strong growth in the volume of international
calls made on IP (+175.0% over one year). Close to half of minutes to international
numbers (46.0%) are now called from IP subscriptions.
After reaching 3.2 billion minutes per quarter from the fourth quarter
2005 to the second quarter 2006, the volume of fixed-mobile calls stabilised
at around 3 billion minutes (-5.8% over one year during the second quarter
2007). Just 11.3% of fixed-mobile call minutes were made using IP subscriptions.

Notes:
- The Observatory distinguishes between calls originating on IP telephony
services and other voice calls. Still, while the volume of VoIP calls covers
all of this traffic observed on the end market, revenue covers only invoiced
VoIP traffic (for example in addition to a multiplay package).
- Volumes and revenue from calls originating on VoIP services are counted
in each of the market segments (long distance, international and to mobiles).
Notes:
- The volume of traffic originating on a fixed line includes calls from
fixed line telephones, public payphones and prepaid phone cards.
- The seasonally adjusted values for this data can be found in the "Séries
chronologiques" spreadsheets available on the ARCEP website


2.1.3 Fixed phonecards and public payphones 

The public payphones activity has been in decline for the past several years.
Over one year, the number of public payphones in service fell by 9 300,
for a 5.4% decline. The revenue and volume of traffic from public payphones
are also down (respectively 24.8% and 7.8% over one year). 2.2 Internet on fixed networksThe growth in the Internet market (number of accesses and revenue) is borne
up entirely by the strength of high-speed accesses (primarily on xDSL but also
on cable, WLL, etc.). High speed represented 88.3% of total accesses and 87.6%
of Internet revenue during the second quarter 2007.
There were 16.1 million Internet accesses (high speed and dial-up) at
the end of the second quarter 2007. The number of subscriptions to high-speed
Internet increased 28.5% over one year, corresponding to over three million
new accesses over the period). In all, there were 14.2 million subscriptions
to high speed at end June 2007.
High-speed Internet revenue reached €1 billion during the second quarter
2007, up 34.1% over one year.
Down sharply for over two years, in the number of accesses un service, in the
number of minutes of connections and in terms of revenue generated, dial-up
Internet now has fewer than two million subscribers.
Note: There may be a time lag between the delivery of a service on the wholesale
market (LLU or bitstream) and its actual availability on the retail market.
A comparison between the data relating to these different markets might reflect
this.


Note: The item "Other Internet services" corresponds to related ISP revenues
such as web hosting or revenues from online advertising. Revenue from the sale
and rental of telephones and terminal equipment is included in the item "Sale
and rental of telephones and terminal equipment by fixed operators and Internet
service providers".


2.3 Television on xDSLThe number of subscriptions to a television service via an xDSL technology
reached 3.8 million at the end of the second quarter 2007. Over two million
additional subscriptions were taken out over one year.


Note: This indicator covers subscriptions which are "eligible" for television
services, i.e. those where subscribers are able to activate this type of service,
regardless of the number of channels available or the pricing plan involved.
It takes into account both standalone subscriptions and those which are part
of a "multiplay" service package, which includes access to one or more other
services besides television (Internet, telephone service). 2.4 Mobile telephony
Note: This item covers both mobile network operators (MNO) and mobile virtual network operators (MVNO).
2.4.1 Subscriptions
The number of customers to a mobile telephony service reached 52.6 million
at the end of the second quarter 2007. The proportion of customers taking out
flat-rate packages (65.7% at the end of the second quarter) continued to grow.
The annual growth rate of the number of customers of mobile telephony remained
strong (+7.1% over one year since the start of the year), although a bit lower
than in the past two years (7.5 to 8% annual growth).
There were 14.6 million customers using mobile operators’ multimedia services
(access to mobile Internet services, MMS, etc.) during the second quarter 2007,
or 28% of mobile operator customers. This proportion, which rose in 2004 and
2005, has been stable since the fourth quarter 2005.


During the second quarter 2007, 154 400 mobile numbers were ported from
one operator to another, for growth of 55.9% over one year. The increase in
the number of ported numbers is due in part to the 21st May 2007
implementation of the simplified mobile number portability procedure (with porting
times shortened from two months to 10 days).
Notes:
- The number of active multimedia users is defined as the number of customers
(contract or prepaid subscribers) who have used a multimedia service such as
Wap, i-Mode, MMS or email (SMS messages are not covered by this definition)
at least once in the past month, regardless of the type of bearer technology
used (CSD, GPRS, UMTS, etc.). Scope: Mainland France and overseas dependencies.
- The number of ported numbers is defined as the number of telephone numbers
effectively ported to another operator (numbers activated by the receiving operator)
during the course of the quarter in question. Scope: Mainland France and overseas
dependencies 2.4.2 Revenue and volume indicatorsRevenue from mobile services (telephony and data transport) reached €4.4 billion
during the second quarter 2007, up 6.3% over one year.
This increase is in line with the 5 to 6% growth rates per quarter observed
since the start of 2006. Annual growth rates were significantly higher in 2005
(8 to 10% per quarter).
Revenue from data transport services on mobile networks (interpersonal messaging,
mobile Internet access and multimedia services) represented €627 million
during the second quarter 2007. The growth in revenue from these services (+18.6%
over one year) remains significantly higher than that of revenue from mobile
calls (+4.5% over one year), although it contributes less than 15% of all mobile
services revenues.


The volume of traffic originating on mobiles represented 25 billion minutes
during the second quarter 2007, up 6.6% over one year. While annual growth in
traffic was at a high level of 15% throughout 2006, it slowed in early 2007
(with respective growth in the first and second quarters of 8.6% and 6.6% over
one year), under the effect of the lower growth of on-net traffic.
There is a clear deceleration in the volume of calls exchanged between mobile
phones on the same network (on-net calls). In early 2006, the growth rate of
this traffic reached 30.8% over one year, but was just 5.5% over one year during
the second quarter 2007.
Conversely, volumes of mobile calls to third-party mobile networks and international
numbers saw new growth over the same period. The volume of calls to fixed phones
continued the decline started in early 2005 (-1.4% over one year during the
second quarter 2007).

(The seasonally adjusted values for this data can be found in the "Séries
chronologiques" spreadsheets available on the ARCEP website)
Interpersonal messaging (SMS and MMS) as a means of communication is clearly
a success: 4.4 billion interpersonal messages were sent during the second
quarter 2007, for a 21.1% increase over one year. The seasonally adjusted series
on the volume of SMS (which represented 99% of interpersonal messages) confirmed
this trend.
On average, each customer sent 28 SMS per month. Customers with a flat-rate
package sent on average close to twice as many SMS as customers using pre-paid
cards (respectively 33 messages and 17 messages per month).


(The seasonally adjusted values for this data can be found in the "Séries
chronologiques" spreadsheets available on the ARCEP website) 2.5 Other market components2.5.1 Value-added services (excluding directory services)Revenue from value-added services reached €583 million during the second
quarter 2007, down 2.8% compared to the second quarter 2006.
This decline is due to the decline in revenue from "voice and telematics" services
originating on fixed lines (down 8.1% over one year). At the same time, revenue
from calls to value-added services made on mobiles rose, for both voice services
(+3.8% over one year) and "data" services (+2.4% over one year).
During the second quarter 2007, 1.1 billion calls were made to voice services,
85% of these calls were made on fixed phones (this also includes calls to telematic
services).
* This corresponds to all amounts billed to customers by operators,
including outpayments from operators to service providers. "Data" value-added
services include premium-rate services such as those on the Orange "Gallery"
portal, push services, chat rooms, weather forecasts, TV game shows, horoscopes,
ringtone downloads, etc.



2.5.2 Directory servicesOne year after the final closure of the old directory services numbers on 3rd April 2006,
and the opening of new 118xyz numbers, telephone directory service activity
has developed in a contrasting manner.
Revenue from directory services, which represented €42 million during
the second quarter 2007, rose 12.8% over one year.
On the other hand, the number of calls to these services fell sharply. During
the second quarter 2007, 35 million calls were made to these numbers, compared
with 41 million during the second quarter 2006, for a 14.5% decline over
one year.
The volume of traffic of calls to directory services numbers represented 72 million
minutes during the second quarter 2007. Just over two-thirds of calls (68.9%)
were made from mobile phones.


Note: Directory information services include: the old fixed-line (12, 3200,
3211, 3212) and mobile (612, 712, 222) information numbers in use until 3rd
April 2006, the new 118xyz numbers in use since November 2005 and the short
numbers used to access reverse lookup directory services (3288, 3217, 3200)
or international directory services (3212). 2.5.3 Leased lines and data transport (fixed operators)
Note : Revenues from leased lines may be accounted for twice as the figures include operator-to-operator sales. These sales may represent up to 29% of total leased-line revenues.
2.5.4 Hosting and call centre management services
- 2.5.5 Telephones and equipmentRevenue from terminal sales and rentals reached €636 million during the
second quarter 2007, of which over two-thirds for mobile operators.
Note: As in previous issues, the revenues from mobile packs and telephones
given here include the commission paid to distributors. 2.6 Indicators per customers
The average monthly invoice per fixed line is calculated
by dividing the revenue from calls originating on fixed lines (line rental,
call charges and Internet service charges) for quarter N by the estimated average
number of fixed lines in existence for quarter N, and then by the number of
months. (See the box on page 28 for an explanation of the concept of "line")
The average monthly invoice per mobile customer is
calculated by dividing the revenue from mobile telephony (voice and data revenues,
including roaming-out, excluding revenue from incoming calls) for quarter N
by the estimated average number of mobile customers for quarter N, and then
by the number of months. This indicator, which does not include interconnection
revenues, or those from value-added services, is not the same as the traditional
Average Revenue Per User (ARPU) indicator.


The average monthly volume of traffic per fixed line
is calculated by dividing the volume of traffic (PSTN and IP) for quarter N
by the estimated average number of fixed lines in existence for quarter N, and
then by the number of months.
The average monthly volume of traffic per mobile operator
customer is calculated by dividing the volume of mobile telephony traffic
(including roaming-out) for quarter N by the estimated average number of mobile
customers for quarter N, and then by the number of months.
The average number of SMS messages per customer is
calculated by dividing the number of SMS messages for quarter N by the estimated
average number of customers for quarter N, and then by the number of months.


The average monthly bill per PSTN subscription is
calculated by dividing the revenue from line rental and calls made from PSTN
fixed lines (i.e. excluding VoIP revenues) for quarter N by the estimated average
number of subscriptions for quarter N, and then by the number of months.
The average monthly invoice per subscription to an IP
telephony service is calculated by dividing the revenue solely from IP calls
billed (i.e. those made on top of those included in a multiplay package) for
quarter N by the estimated average number of subscriptions for quarter N, and
then by the number of months.
The average monthly invoice per dial-up (or broadband)
Internet subscription is calculated by dividing the revenue from the dial-up
(or broadband) Internet connections for quarter N by the estimated average number
of customers for quarter N, and then by the number of months.



The average monthly volume of PSTN (or IP) traffic
is calculated by dividing the volume of PSTN (or IP) traffic for quarter N by
the estimated average number of subscriptions to a PSTN (or IP) telephone service
for quarter N, and then by the number of months.
The average monthly volume of dial-up Internet traffic
is calculated by dividing the volume of dial-up Internet traffic for quarter
N by the estimated average number of subscriptions to a dial-up Internet service
for quarter N, and then by the number of months.

Average number of customers for quarter N: [(total
number of customers at the end of quarter N + total number of customers at the
end of quarter N-1) / 2]
Further information concerning the average monthly invoice
and volume indicators
With the growing use of broadband voice services as a second
line, using the average revenue per subscription is no longer of much use as
an indicator. In fact, a large number of households now have a second telephone
service subscription, usually a VoIP service, but this doesn’t mean that they
make twice as many calls. Consequently, the average volume of traffic and average
bill per subscription is, naturally, lower. In order to obtain a clearer picture
of the indicators reflecting customers’ use of telephone services and their
average expenditure, the concept of what constitutes a "line" has been redefined.
Until 2004, the terms "line" and "subscription" were used interchangeably
when referring to the number of subscriptions to telephone services.
In the case of telephony over analogue lines, a subscription
corresponded to a fixed line. It was accepted practice, in the case of digital
lines, to take the number of channels subscribed to as the number of fixed lines,
i.e. two for BRI lines and up to 30 for PRI lines. In practice, the business
customer pays as many monthly line rental charges as the number of channels
subscribed for, i.e. two for BRI lines and up to 30 for PRI lines. This convention
has been retained.
With the implementation of broadband voice services, operators
can provide an IP telephone service over an analogue line which is already used
for a PSTN telephone service. In order to facilitate comparisons over time,
the "number of lines" indicator has been defined as:
- for digital lines: the
number of channels subscribed for, i.e. two for BRI lines and up to 30 for PRI
lines;
- for analogue lines - the
PSTN subscriptions
- the xDSL line subscriptions
without a PSTN subscription;
- for cable telephone service
subscriptions: the subscription
As far as revenues are concerned, the number of multiservice
packages is constantly growing. These include the possibility of making unlimited
calls to national fixed lines and to certain international destinations at no
additional charge. Consequently, the overall bill covers an increasing range
of services, regardless of the number of calls made (this also happens with
mobile services). Internet access and telephone services are becoming increasingly
inseparable.
The average invoice per line reflects what the customer pays
per month for both telephone service and Internet access. The revenues taken
into account are:
- revenues from service subscription charges and supplementary services
- revenues from calls made from fixed-line telephones, including IP calls
made on top of the multiplay inclusive package
- revenues from dial-up Internet access and broadband Internet access
The following are not taken into account:
- revenues from payphones and phone cards
- revenues from other services linked to the Internet access, which correspond
to the ISP revenues from online advertising and commissions paid to the ISPs
in relation to online trading
- revenues from value-added services and information services

Average invoice and average volume per customer, ARPU or AUPU
– How do they differ?
The market Observatory publishes indicators for the average
monthly invoice per subscription for fixed telephony, mobile telephony and Internet.
These indicators correspond to the average subscription and call charges
(voice and data) billed by operators to customers.
Revenues from interconnection (incoming calls) are not taken
into account. These indicators are not the same as the ARPU
(Average Revenue Per User) figures which corresponds generally to
the operators’ revenues from all revenue related to the use of the network.
For instance, in the case of mobile operators, the ARPU includes the revenue
from outgoing calls, data services and value-added services as well as
the revenue from incoming calls (interconnection). It may or may not include
revenue from roaming, depending on the operator.
The Observatory also publishes indicators for the average
monthly outgoing traffic per customer, representing the use consumers
make of their telephone.
As with the ARPU, the indicator of average traffic per customer
or AUPU (Average Usage Per User) is used by certain financial firms and
the operators. It covers some or all of the incoming calls in order to create
a figure for volume which is comparable to that used for the ARPU. It does not
represent the average usage per customer and is considered rather as an indicator
of the operator’s volume of business per customer.
