Method and system for registering internet protocol multimedia subsystem (IMS) service

Abstract

The invention discloses a method and a system for registering internet protocol multimedia subsystem (IMS) service. The method comprises the following steps: a session initiation protocol (SIP) server receives the IMS service information sent by a sender; the SIP server judges whether a terminal user of a receiver registers the IMS service; if the terminal user of the receiver does not registers the IMS service, the SIP server indicates that a short message system sends the short message for reminding the terminal user of the receiver of registering the IMS service to the terminal user of the receiver; the terminal user of the receiver displays the short message for reminding the terminal user of the receiver of registering the IMS service, wherein the short message comprises an IMS service registering accepting hyperlink option and an IMS service registering refusing hyperlink option; the terminal user of the receiver receives the IMS service registering request send through the IMS service registering accepting hyperlink option and sends the IMS service registering request to the SIP server; and the SIP server registers the IMS service for the terminal user of the receiver according to the preset IMS service registering procedure. The invention can remind the terminal user of the receiver of registering the IMS service in time and can automatically finish the IMS service registration for the terminal user of the receiver.

Description

technical field [0001] The present invention relates to an IP Multimedia Subsystem (Internet Protocol Multimedia Subsystem, hereinafter referred to as: IMS) service, in particular to a registration method and registration system for the IMS service. Background technique [0002] With the development of communication technology, IMS services have been more and more commonly used. The IMS service uses the Session Initiation Protocol (Session Initiation Protocol, SIP for short) as the call control signaling. When users use IMS services, they need to start the IMS service client to register with the SIP server. After the registration is successful, the relevant IMS services are activated and users can use IMS services through the IMS service client. [0003] Since the IMS service is based on IP, the user needs to log in to the packet domain when registering the IMS service, and certain traffic charges will be generated at this time. In order to save service costs, or due to o...

AI Technical Summary

Problems solved by technology

In order to save business costs, or due to other reasons such as usage habits and users' inability to know and register new services in a timely manner, many users did not register for IMS services in the early days of IMS services.

The IMS service is generally a point-to-point communication service between user terminals and user terminals. If the receiving terminal user has not registered for the IMS service, even if the receiving terminal has connected to the network, it cannot receive the registered IMS service. The IMS service information or invitation message sent by the sender terminal, so that the receiver terminal user cannot register for the IMS service and use the IMS service in time
