Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be noted that the following preferred embodiments are provided to provide a comprehensive and thorough understanding of the present invention, but not to limit the present invention.

[0032] The main ideas for restoring the subscription session in the technical solution of the present invention are:

[0033] When the server (for example, the presence server PS) learns that the subscription notification message sent to the client fails to be sent, after deleting the session, an instant message (Message message) is sent to the client (also called an observer, that is, a user terminal), through which The instant message informs the client that the subscription session fails, and the client is expected to restore the session and re-establish the subscription ...

Abstract

An IP multimedia subsystem and method thereof for restoring a user subscription relationship are provided in the present document. The method includes: a client initiating a subscription request to a server after making a successful registration, and the server sending subscription notification message to the client after receiving the subscription request; after sending the subscription notification message, if acquiring that the sent subscription notification message is sent unsuccessfully, the server sending instant message to the client to notify that the subscription notification message is sent unsuccessfully; and after receiving the instant message and acquiring that the subscription notification message is sent unsuccessfully, the client re-initiating a subscription request to the server. In the present document, the user experience can be improved, and the usage effect of users can be enhanced.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an IP multimedia subsystem and a method for restoring user subscription relationship. Background technique [0002] IP Multimedia Subsystem (IMS, IP Multimedia Subsystem) is a standard for next-generation networks defined by the Third Generation Partnership Project (3GPP). Its notable feature is the use of Session Initiation Protocol (Session Initiation Protocol, SIP for short) system, communication has nothing to do with access, has a variety of business integration capabilities, and conforms to the development trend of communication network integration. [0003] Presence (PRS for short) is a service capability that allows users to publish their own presence information, allows users to query another user's presence information, or successfully subscribes to another user's presence information After the Presence information is changed, the user is notified of the change o...
