Embodiment Construction

[0063] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0064] According to an embodiment of the present invention, a subscription method for multi-terminal users based on an IP multimedia subsystem is provided. The method can be used in a network environment including an Application Server (AS) and a Serving Call Session Control Function (S-CSCF), for example, the IMS system shown in FIG. 1 . In addition, as mentioned above, a multi-terminal user refers to a user whose multiple terminals share a common user identity (PUI).

[0065] As shown in Figure 5, the subscription method of multi-terminal users based on the IP multimedia subsystem according to the embodiment of the present invention includes the following processi...

Abstract

The invention discloses a subscription method of multi-terminal users based on an IP multimedia subsystem. The method comprises the following steps: an application server processes a third party registration request from a S-CSCF terminal; the application server checks whether a common user ID corresponding to the terminal has made a state subscription; the application server initiates a state subscription request to the common user ID under the condition that the common user ID doesn't make the state subscription, or the application server doesn't initiate the state subscription request under the condition that the common user ID has made the state subscription. The invention can efficiently reduce the resource occupancy during the subscription process, particularly reduce the invalid occupancy of network resources due to repeated identical subscriptions, so that the efficiency is increased, the operating cost is reduced and the network user capacity is increased.

Description

technical field [0001] The present invention relates to the field of communication, in particular to a (application server) subscription method for multi-terminal users in an IP multimedia subsystem. Background technique [0002] IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) is the standard of the next generation network defined by the third generation partnership organization (3rd Generation Partnership Project, referred to as 3GPP). SIP for short) system, communication and access have nothing to do, can have a variety of media business control function and bearer capacity separation, call and session separation, application and service separation, business and network separation, and mobile network and Internet service integration, etc. ability. The proposal of IMS complies with the development trend of communication network convergence. [0003] In IMS, a user can have multiple different terminals, called multi-terminal users, and these multiple terminal users ...
