Embodiment Construction

[0021] The technical solutions of the embodiments of the present invention will be described in further detail below with reference to the drawings and embodiments.

[0022] The embodiment of the present invention is aimed at the technology of GERAN carrying CS domain voice services, and the technology is applicable to full rate (Full rate, hereinafter referred to as: FR), half rate (Half Rate, hereinafter referred to as: HR), enhanced full rate (Enhanced Full Rate) , hereinafter referred to as: EFR) and AMR and other voice services. Using this technology, the voice coding rate can be increased, the voice quality can be improved, the multiplexing and resource sharing of the CS domain and the PS domain can be realized, the spectrum efficiency can be improved, and the network capacity can be improved. GERAN related technologies can be applied to voice services to realize CS Technology sharing between domain and PS domain. Based on this technology, RLC / MAC is not only used to be...

Abstract

The embodiment of the invention relates to a method and a device for adjusting a speech frame encoding mode. The method comprises the following steps: acquiring a data block encoding rate; determining the highest encoding rate available to a speech frame carried by a channel according to the data block encoding rate and the number of terminals multiplexed in the channel; determining the selected speech frame encoding rate according to a preset candidate encoding rate set and the highest encoding rate available to the speech frame; and adjusting the speech frame encoding mode according to the selected speech frame encoding rate. The embodiment of the invention can adjust the AMR encoding mode without acquiring a channel carrier-to-interference ratio, guarantees normal multiplexing between users, effectively improves resource-sharing performance between CS domain services and between a CS domain service and a PS domain service, and further improves system capacity.

Description

technical field [0001] The embodiments of the present invention relate to the field of communications, and in particular, to a method and device for adjusting a voice frame coding mode. Background technique [0002] The Global System for Mobile Communications (Global System for Mobile Communications, hereinafter referred to as: GSM) has two services: Circuit Switched Domain (hereinafter referred to as CS domain) and Packet Switched Domain (hereinafter referred to as PS domain). , where the voice service in the CS domain adopts the Dm channel link connection protocol (Link Access Protocol the Dm channel, hereinafter referred to as: LAPDm) at layer 2 (L2), and exclusively occupies the channel, and each time slot (timeslot, hereinafter referred to as: TSL) It can bear up to two voice services; the data service in the PS domain adopts the Radio Link Control (Radio Link Control, hereinafter referred to as: RLC) / Media Access Control (hereinafter referred to as: MAC) protocol at L2...
