Abstract

The embodiment of the invention provides a group calling method and a group management server to realize CF addressing. The group calling method is based on a cluster server, the cluster server comprises a PF entity and a GSM functional entity, and a mapping relation between a group identifier (GID) and a service control function (CF) service identifier is maintained on the GMS functional entity. The method comprises the following steps that the PF entity receives a join request (carrying a target GID); if the mapping relation matched with the target GID is not locally stored, the PF entity obtains corresponding CF configuration information from the GMS according to the target GID, wherein the CF configuration information at least comprises a CF service identifier; and the PF entity locally stores the mapping relation between the target GID and the obtained CF service identifier, so that CF addressing is completed.

Description

Technical field [0001] The present invention relates to the field of communications, and in particular to a group calling method and a cluster server. Background technique [0002] MCS (Mission Critical System) is a complete set of communication systems established on LTE in order to resolve public safety. MCPTT (Mission Critical Push To Talk) provides a voice cluster communication service as an important part of the MCS system. [0003] McPTT can provide a call function (group call), and the current MCPTT standard has the following two points required: [0004] 1. The group call service of a group is unified on a specific CF (Controlling function, business control function) entity, and the CF entity is responsible for the call control and the right management of the call. [0005] 2. When the user initiates a call, please see figure 1 The group call request first reaches the primary PF (ParticipatingFunction, User Management) entity, and the PF entity adds to the CF entity corre...
