PTT group call controlling method, system and equipment

Abstract

The embodiment of the invention discloses a method for controlling PTT group session, which comprises the following steps: transmitting first control requirement information to a network side device, wherein the information carries a group sign and the number of a user end, receiving first control responding information responded by the network side device, wherein the resounding information carries a control state sign, and the control state sign is used for indicating the state of the user end. In the embodiment of the invention, a master control party can observe the state of each member in session in real time after initiating the session and can control the session group during the session according to the requirements, which increases the flexibility of PTT application, enables the PTT to be suitable for a wider application range and satisfy the application requirements of more individuals.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a PTT group call control method, system and equipment. Background technique [0002] PTT (Push To Talk) is a new application based on 3G network, and it is a Voiceover IP technology. Different from traditional voice communication based on circuit switching, PTT implements voice communication in the form of digital switching, converts voice signals into data packets and transmits them through the network, and finally converts data packets into voice signals to come out from the network side to complete a call. At the same time, because PTT is a data application, it can be managed by data. For example, PTT users can establish a friend contact database, and can know who is talking now, whether the contact person is in the service area, etc., and can also be expanded to achieve User customized needs. PTT can carry out group multi-person calls, has the advantages of go...

Problems solved by technology

[0004] The current PTT group call can only be carried out by setting the group in advance, especially the application of the fixed group needs to be pre-set on the network side, and it is impossible to realize the selective group call through the mobile terminal

Moreover, once a group call is initiated, the members in the group cannot be effectively controlled in real time, and the status of the members in the group is invisible to other members, so the caller cannot know whether the members in the group are in this time In the middle of a call, which will affect the effect of group calls
