Problems solved by technology

Therefore, the voice codec method negotiated by the above-mentioned terminals during SIP pre-establishment is more likely to be inconsistent with the data codec delivered by the multicast channel, and the problem of listening freezes is also common.

Embodiment Construction

[0030] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and examples.

[0031] For the above-mentioned problem of monitoring stuttering, if both the server and the terminal use unicast technology for voice monitoring, that is, no pre-establishment is used, this problem can be solved. However, there will also be the following problems: (1) if SIP pre-establishment is not used, the capacity of the server will be greatly reduced; (2) if SIP pre-establishment is not used, the establishment delay of the monitoring session will be increased; (3) according to statistics, In a large-scale system, only a few terminals have different codecs, so it is not appropriate to use SIP non-pre-established methods.

[0032] Based on the above analysis, in order to make full use of the advantages of SIP pre-establishment and avoid the pro...

Abstract

The invention discloses a cluster voice multicast group call monitoring method and device, and the method comprises the steps: initiating SIP pre-establishment to a server after a terminal logs in successfully; when the terminal receives a MAP message sent by the server, enabling the terminal to judge whether a voice coding format indicated by the MAP message is the same as a voice coding format negotiated during SIP pre-establishment, and if the voice coding format indicated by the MAP message is the same as the voice coding format negotiated during SIP pre-establishment, performing voice monitoring according to the MAP message; otherwise, triggering the server to build voice unicast for the terminal, and monitoring the corresponding unicast voice. By applying the technical scheme disclosed by the invention, the problem of terminal monitoring lag can be effectively solved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a monitoring method and device for trunking voice multicast group calls. Background technique [0002] At present, the broadband trunking solution based on the 3GPP trunking application layer standard (Mission Critical Push To Talk over LTE, MCPTT) has entered a new era. Compared with traditional private network services, the MCPTT standard solution has been greatly improved, and a series of new technologies have been added, such as Session Initiation Protocol (Session Initiation Protocol, SIP) pre-establishment, multicast group call, etc. When the terminal and the server support SIP pre-establishment, after the terminal successfully logs in, the terminal establishes a session path with the server based on the SIP protocol (mainly for parameter negotiation between the terminal and the server, such as voice codec mode), and saves it for a long time . When th...
