Description

IMS group providing method and device Technical Field The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for providing an IMS group. Background The IP multimedia subsystem (IP Multimedia Subsystem, IMS) is an architecture defined by the third generation partnership project (3rd Generation Partnership Project,3GPP) standard organization that provides multimedia services based on internet protocols (Internet Protocol, IP). In the IMS network, an IMS group is created for the UE or the third party application server by an IMS group management application server, and the IMS group provided by the IMS group management application server is called by an IMS value added service application server to provide corresponding value added services for the UE or the third party application server. Here, group members of one IMS group may include a plurality of UEs, and one IMS group may be applicable to various value added services, for example, a chat service, a message distribution service, etc., or may be applicable to only one value added service. In these IMS groups, there is generally no IMS group related to location information, which makes an IMS value added service application server unable to provide specific value added services in an application scenario related to location information, for example, unable to provide emergency broadcast services in a specific area, which results in poor user experience of related users, so how to provide an IMS group based on location information is one of the technical problems that needs to be solved currently. Disclosure of Invention In order to overcome the problems in the related art, the application provides a method and a device for providing an IMS group.
