Method and system for group voice data processing and terminal device

Abstract

The invention provides a method and a system for group voice data processing and a terminal device. The method includes that a regional resource center (RRC) reconfigures the logic channel number and the wireless bearing number to build a packet data convergence protocol (PDCP) entity, a radio link control (RLC) entity and a multi-access computer (MAC) entity according to pre-acquired logic channel numbers and default wireless bearing numbers of a group voice signaling channel and a group voice business channel; a physical layer (PHY) receives the group voice signaling channel or the business signaling channel and then transmits the channels to the MAC, and the MAC transfers the channels to the PDCP through the RLC; the PDCP transmits the group voice signaling channel to the RRC, generates a CS count value according to PDCP serial numbers and transmits the CS count value and the group voice business channel to a coding and decoding module; and the coding and decoding module conducts decoding processing according to the CS count value. By means of the technical scheme, adaptive multi rate (AMR) group voice business is achieved in a long term evolution (LTE) system.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a group voice data processing method, system and terminal equipment. Background technique [0002] With the continuous development of wireless communication technology, trunking communication technology develops from analog system to narrowband digital trunking system. At the same time, as industry users gradually increase their demand for wireless broadband, industry users have higher and higher requirements for the quality of voice services. In order to meet the needs of industry users, the traditional trunking system will withdraw from the market and will be replaced by TD-SCDMA Long Term Evolution (TD-SCDMA Long Term Evolution) , TD-LTE) as the representative digital trunking communication system. [0003] In the 3rd Generation Partnership Project (The 3rd Generation Partnership Project, 3GPP), the LTE system uses Voice over Internet Protocol (VoIP) technology to...

AI Technical Summary

Problems solved by technology

[0003] In the 3rd Generation Partnership Project (The 3rd Generation Partnership Project, 3GPP), the LTE system uses Voice over Internet Protocol (VoIP) technology to support voice services. The point-to-point communication of the main users cannot support point-to-multipoint trunking communication. Therefore, for industry users, the AMR group voice service with relatively mature technology and low requirements for terminal equipment is a preferred solution
