Embodiment Construction

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] figure 1 The flow chart of the IMS instant message transfer method provided by the embodiment of the present invention, such as figure 1 As shown, the specific steps are as follows:

[0039] Step 101: When an IMS user equipment (UE, User Equipment) wants to sign up for an instant message transfer service, it initiates an instant message transfer service subscription request message to an IM application server (AS, Application Server), and the message carries the IP multimedia service of the IMS UE Public identity (IMPU, IP Multimedia Public Identity).

[0040] For example: IMS UE a can bind itself to a mobile terminal b, so that when IMS UE a is not registered or offline, instant messages sent by other IMS UEs can be transferred to mobile terminal b.

[0041] Step 102: The IM AS receives the instant message transfer service ...

Abstract

The invention discloses an instant messaging (IM) transfer method of an IP multimedia subsystem (IMS) and an instant messaging application server (AS). The method comprises the following steps that: an IM AS receives a session initiation protocol (SIP) IM sent by calling IMS user equipment (UE); if called IMS UE is found to be unregistered or be not on-line and the called IMS UE signs an IM transfer service, the SIP IM is converted into a short message and a destination number of the short message is a mobile station international integrated service digital network (MSISDN) number of a mobile terminal bound to the called IMS UE; and the short message is forwarded to the mobile terminal by a short message gateway and a short message platform. According to the invention, on the condition that an IMS user is not registered or is not online, an IM can still be received by a bound mobile terminal.

Description

technical field [0001] The invention relates to the technical field of instant message services, in particular to an IP multimedia subsystem (IMS, IP Multimedia Subsystem) instant message transfer method, an instant message application server, and a short message gateway. Background technique [0002] With the rapid development of Internet technology and the maturity of operators' full-service operations, Instant Messaging (IM, Instant Messaging) based on IMS network, as a personal communication tool, has excellent expressiveness, interactivity, real-time, and can Realizing text, voice, video, image and other multimedia instant communication, it is favored by office white-collar workers, fashionable people and the majority of students, and has become the main form of expression in people's daily life in addition to short messages. However, when the status of the IMS network user is unregistered such as away or offline, the user cannot receive instant messages in time, which ...
