Embodiment Construction

[0082] The invention provides a method for storing, forwarding and converting processing based on the IMS message, so as to realize the transmission of the IMS message to the called terminal.

[0083] The method of the present invention includes: the user terminal sends a message based on the initial session protocol (SIPMessage) to the called user, and if the called user terminal is not currently registered in the IMS network, if the user has registered an unregistered service, then the message is stored ; If the current called user has registered to send messages through other currently registered networks or the operator's policy requirements, then convert the message format and forward the message to the called user through other types of networks registered; otherwise, wait After the called user registers in the IMS network, the message is forwarded to the called user.

[0084] The method of the present invention will be described in detail below in conjunction with the a...

Abstract

An instant message transmitting method and apparatus for IP multimedia subsystem. The method of the present invention comprises: after network received IMS instant message that calling user transmited to called user, inquire the current register status of called user. If the called user hasn't registered in IMS network, but the called user has registered the unregister service, then transmitting the IMS instant message of calling user transmitted to one message application server. After the called user registered in the IMS network, transmitting the stored IMS instant message to the called user; or transferring the IMS instant message to other format messge corresponding to the other network that the called user currently register. The apparatus of the present invention comprises: message receive module and message analyse module and message application server. The present invention ensures IMS message be transmitted to the called terminal by store and transfer mechanism of IMS message.

Description

technical field [0001] The present invention relates to mobile network services, in particular to an IP Multimedia Subsystem (IMS) instant message transmission method and device. Background technique [0002] With the rise and development of various IP access technologies, how to convert existing mobile network services into services that IP terminals can provide has become a goal of the 3rd Generation Partnership Project (3GPP) standardization organization. Considering that networks based on IP access methods are becoming more and more common, such as WLAN networks and NGN networks, for various IP terminals, or multi-mode terminals that support IP access methods and mobile network access methods, such as WLAN and WCDMA / GSM multi-mode terminals, how to reuse existing mobile network service function entities and protocols as much as possible, and access to the mobile core network through the IP-based access network is a common concern of operators. [0003] At present, ther...
