Embodiment Construction

[0044] For a method for determining a called access domain provided by an embodiment of the present invention, see figure 1 As shown, the following steps may be included:

[0045] 1. The AS to which the called user belongs receives the call request (SIP INVITE).

[0046] 2. The AS that receives the call request requests T-ADS information from the Home Subscriber Server (HSS) to which the called user belongs through a User Data Request (USERDATAREQUEST, UDR) message;

[0047] The UDR message includes the requested information type, the identification information of the called user, such as IP Multimedia Public Identity (IPMultimediaPublicIdentity, IMPU) or Mobile Subscriber Number (MobileSubscriberInternationalISDN / PSTNnumber, MSISDN), and the ISDN refers to the Integrated Services Digital Network, It is the abbreviation of Integrated Service Digital Network, and the PSTN refers to the public switched telephone network, which is the abbreviation of PublicSwitchedTelephoneNetwo...

Abstract

The invention discloses a terminating-access domain determining method and server. The method comprises that a triggered application server (AS) requests the acquisition of terminating-access domain selection (T-ADS) information of a user and an IP multimedia subsystem (IMS) register state from a home subscriber server (HSS), and transmits an IP multimedia public identity (IMPU) to the HSS; the AS receives a request result returned by the HSS, the request result includes a query result, the T-ADS information and the IMS register state, and the T-ADS information and the IMS register state are information acquired through a query by the HSS according to the IMPU; and the AS determines an access domain according to the request result.

Description

technical field [0001] The present invention relates to communication technology, in particular to a method and server for determining a called access domain. Background technique [0002] At present, when the application server (Application Server, AS) to which the called user belongs receives a call request (SIP INVITE message), because the called user may be in different network coverage states, the network coverage states can be divided into supporting IMS voice, not Supports IMS voice, IMS is registered, IMS is not registered, so it is necessary to perform the called access domain selection (Terminating-AccessDomainSelection, T-ADS) process to determine whether the call is accessed from the IP Multimedia Subsystem (IPMultimediaSubsystem, IMS) domain or from the Circuit switched (CS) domain access. [0003] However, for the following cases: [0004] 1. When querying, the user indicates that MSISDN is used, and the user who has signed a VoLTE (VoiceoverLTE) service uses...
