Problems solved by technology

[0011] The transmission resource between Node B and RNC has always been one of the key points that operators pay attention to, but in the DCH FP voice frame transmitted by the existing Iub interface, the number of bytes occupied by the header field is relatively large (5 bytes), Resulting in low transmission efficiency of Iub interface voice services

Embodiment Construction

[0038] The embodiment of the present invention proposes two voice service transmission methods, including the transmission in the downlink direction and the uplink direction. Specifically include:

[0039] Downlink direction: a voice service transmission method, including:

[0040] receiving a DCH FP voice frame carrying an RFCI, where the RFCI is used to indicate the length of the TB in the DCH FP voice frame;

[0041] Determine the corresponding TFI indicating the TB length according to the correspondence between RFCI and TFI and the RFCI in the received DCH FP voice frame.

[0042] Uplink direction: a voice service transmission method, including:

[0043] According to the preset TFI, search for the correspondence between the RFCI and the TFI contained in the message, and obtain the RFCI corresponding to the TFI;

[0044]adding the obtained RFCI into the DCH FP voice frame, and sending the DCH FP voice frame carrying the RFCI.

[0045] The following embodiments only take...

Abstract

The invention provides a voice service transmission method and device. The method comprises: receiving speech frame of dedicated channel frame protocol, the RFCI being used for indicating transmission block length of DCH FP speech frame; determining corresponding TFI for indicating TB length according to corresponding relation of RFCI and transmission format indication TFI and received RFCI in DCH FP speech frame. The transmission method and device of the invention can promote voice service transmission efficiency of Iub interface.

Description

technical field [0001] The invention relates to the technical field of mobile communication systems, in particular to a voice service transmission method and device. Background technique [0002] Universal Mobile Telecommunication System (UMTS, Universal Mobile Telecommunication System) is a third-generation mobile communication system that adopts Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access) air interface technology, see figure 1 , figure 1 It is a schematic structural diagram of a UMTS system in the prior art. The UMTS includes a UMTS Terrestrial Radio Access Network (UTRAN, UMTS Territorial Radio Access Network), a core network (CN, Core Network) and a user equipment (UE, User Equipment). Among them, UTRAN includes one or several radio network subsystems (RNS, Radio Network Subsystem), and one RNS is composed of one radio network controller (RNC, Radio Network Controller) and one or more base stations (Node B). The interface bet...
