Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0032] In the scenarios involved in the present invention, the user UE has the ICS capability, and the VMSC of the visited network integrates the L-CAAF-n capability.

[0033] The idea of ​​the present invention is that the L-CAAF-n function in the VMSC will monitor the USSD message sent by the user UE to the home network, and when it is found that the user UE has the L-CAAF capability (that is, the user UE is an ICS UE), the UE , the L-CAAF-n function in VMSC will be shielded.

[0034] The invention includes the following steps: the integrated L-CAAF-n function of the VMSC will monitor the USSD message between the user UE and the home network (the message must be forwarded by the VMSC). If the L-CAAF-n finds in the message that the UE has the ICS capability, then the L-CAAF-n functio...

Abstract

A calling / registering method for a consumer device to access to an IP multimedia sub-system including the following steps, (1) the consumer device sends out information to the circuit domain control function of the IP multimedia sub-system ICCF and the information is transmuted through a visiting movable switching centre VMSC ;( 2) the local CS access adapting network equivalence L-CAAF-n function in the VMSC checks the information and screens the L-CAAF-n function in the VMSC aimed at the consumer device when the consumer device is confirmed to be provided with the centralized service capability ICS of the IP multimedia sub-system according to the content of the information. The invention solves the repeat operation problems caused by that both an UE and the VMSC are provided with a L-CAAF function thereby avoiding signaling waste.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to the IP (Internet Protocol, IP for short) multimedia subsystem (IP Multimedia Subsystem, IMS for short), in the IMS Centralized Service (IMS Centralized Service), user equipment access Calling / registration method of the IMS system. Background technique [0002] The IP Multimedia Subsystem is an IP-based network architecture proposed by the 3rd Generation Partnership Project (3GPP), which builds an open and flexible service environment, supports multimedia applications, and provides users with rich multimedia business. [0003] IMS is an IP-based telecommunications network architecture and has nothing to do with access technology. In addition to providing services for packet access networks such as GPRS (General Packet Radio Service) and WLAN (Wireless Local Area Network, wireless local area network), it also provides It can provide services for mobile cellul...
