7、of a pre-IMS FMC network environment. ITU-T Recommendation Q.1763/Y.2803 defines the service features, service architecture, and capability requirements of the convergence service between legacy PSTN and ISDN and mobile networks. An example of the implementation of the converged service is provided.

The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, opera
10、ting and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, pr
11、oduce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In t
12、his Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g., i
13、nteroperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not sugges
14、t that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the eviden

32、ation, the capabilities that provide service and application to the end-user regardless of the fixed or mobile access technologies being used and independent of users location. In the NGN environment, it means to provide NGN services to end-users regardless of the fixed or mobile access technologies
33、 being used. 3.1.2 nomadism ITU-T Q.1761: Ability of the user to change his network access point after moving; when changing the network access point, the users service session is completely stopped and then started again, i.e., there is no handover possible. It is assumed that the normal usage patt
34、ern is that users shut down their service session before moving to another access point or changing terminal. This is the mobility alluded to in the case of fixed-mobile convergence. 3.2 Terms defined in this Recommendation There are no terms defined in this Recommendation. 4 Abbreviations and acron

In addition: “he“ should be read as gender neutral, that is referring to “he“ or “she“ as appropriate; and “his“ should similarly be read as gender neutral. 6 Service features The PAM service provides a mobile user with access to voice and video telephony services utilizing the PSTN/IS
43、DN via an available access point (AP) with an appropriate dual mode mobile terminal. Whether the AP is connected to the legacy network via a PSTN analogue or an ISDN access interface does not affect the service from the PAM users point of view. The dual mode dual radio mobile terminal provides the u
44、ser the accesses to the legacy PSTN/ISDN and mobile networks using a single terminal. 6.1 Service numbering The PAM service supports two types of numbering: The user is identified by a discrete PAM service number (referred to as a “fixed PAM service number“ which may be in the form of, e.g., an UPT
45、number). The fixed PAM service number is used separately from the users mobile number (MSISDN). The fixed PAM service number is used to make and receive calls when the user is being provided service by means of a PSTN/ISDN access, while the mobile number (MSISDN) is used when the user is being provi
46、ded service by means of a mobile network access. The user is identified by his MSISDN, which is also his PAM service number, independent of whether he is being provided service by a PSTN access or a mobile network access. 6.2 Service subscription The user needs to subscribe to the PAM service in adv
47、ance. When the fixed PAM service number is used, the subscription information is as follows: a fixed PAM service number assigned by the provider; a user identity assigned by the provider which links to the PAM service number of the user; the users associated MSISDN for re-routing the terminating cal
48、l to the mobile network in case the call is not possible to be completed through the PSTN/ISDN; the service access code (SAC) of PAM service which corresponds to the PAM service controlling point of the home network. ITU-T Rec. Q.1763/Y.2803 (10/2007) 5 When a MSISDN is used as the PAM service numbe
49、r, the subscription information is as follows: the users IMSI; a user identity assigned by the provider which links to the IMSI of the user terminal; the service access code (SAC) of PAM service which corresponds to the PAM service controlling point of the home network; the PAM service subscription to be registered in the users service profile (in the HLR/AuC (HSS). 6.3 Registration and authentication for legacy fixed network access The mobile user needs to register at a fixed network a
