Embodiment Construction

[0027] In order to make the purpose, technical solutions and advantages of the examples of the present invention more clear, the technical solutions in the examples of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the examples of the present invention.

[0028] Broadband Trunking Communication (B-TrunC for short) is a TD-LTE-based "LTE digital transmission + trunking voice communication" private network broadband trunking system standard developed by the Broadband Trunking (B-TrunC) Industry Alliance.

[0029] In the BTrunC communication service, some terminals or networks support different voice systems. Generally speaking, when transmitting data in the BTrunC network, the sender needs to encode the data to be transmitted, and then send it to the peer through the transport layer, and after being received by the peer, the data is obtained after decoding. The encoding of the transmission data can adopt the ...

Abstract

The invention provides a voice system switching method, core network equipment, cluster group equipment and a cluster group. The method comprises the following steps: when determining that a cluster group needs to switch a voice system according to a preset condition, sending a first message to cluster group equipment; inserting a voice system change identification packet into a to-be-sent data packet flow, and sending the to-be-sent data packet flow to the cluster group device, wherein the voice system change identification packet is used for indicating a data packet behind the voice system change identification packet to be processed in the switched voice system. That is to say, the special voice system change identification packet is inserted into the to-be-sent data packet flow, so that the cluster group equipment can accurately judge the voice system switching time and process according to the new voice system after the identification packet, thereby realizing the switching of different voice systems in one service session. Therefore, service loss is reduced and the reliability of the service session is improved.

Description

Technical field [0001] The invention relates to the field of communications, and in particular to a voice standard switching method, core network equipment, cluster group equipment and cluster group. Background technique [0002] Broadband Trunking Communication (B-TrunC for short) is a private network broadband trunking system standard based on TD-LTE for "LTE digital transmission + trunking voice communication" formulated by the Broadband Trunking (B-TrunC) Industry Alliance. [0003] In the BTrunC communication service, terminals or networks may support different voice formats. Therefore, when a terminal that only supports a certain voice format accesses a trunking group that uses another voice format, if the trunking group does not switch voice formats, the new The connected terminal cannot correctly parse the voice data, causing service losses. Currently, there is no defined mechanism for switching between different voice standards in a business session. [0004] There...
