Embodiment Construction

[0052] The core of the present invention is that when the mobile terminal and the base station system negotiate a service agreement, the mobile terminal and the base station system negotiate the parameter by carrying the RLP parameter that identifies no service retransmission in the service request message. If the negotiation passes, then It can support the non-retransmission of forward and reverse packet data traffic channels; if the negotiation fails, the terminal can adopt the method of not sending NAK (negative acknowledgment) frames to realize non-retransmission of forward packet data traffic channels.

[0053] Those skilled in the art know that WCDMA (Wideband Code Division Multiple Access) / CDMA2000 is a third-generation mobile communication system, which adopts a structure similar to that of the second-generation mobile communication system. From the perspective of system structure and functions, it includes wireless access Access Network (RAN) and Core Network (CN). Am...

Abstract

The method includes steps: when building service in real time, base station system sends message of channel assignment to mobile user terminal; based on the message of channel assignment, mobile user terminal builds service channel; starting up transaction negotiation with content of negotiation as operation parameters in wireless link protocol; based on result of the said negotiation, the method realizes non-retransmission in transaction channel when real time transaction is transmitted. The invention reduces time delay of real time transaction caused by RLP retransmission.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for transmitting real-time services in a code division multiple access system. Background technique [0002] With the development of computer technology, optical fiber communication technology, digital technology, switching technology and voice compression technology, voice network and data network have shown a trend of integration, resulting in VoIP (Voice Over Internet Protocol) network telephone to meet people's needs for real-time calls. need. The so-called VoIP uses the IP packet switching network as the transmission platform to perform a series of special processing such as compression and packaging on the analog voice signal, so that it can be transmitted using the connectionless UDP (User Datagram Protocol) protocol. Compared with the traditional circuit-switching-based telephone network, VoIP uses TCP / IP (Transmission Control Protocol / Internet Protocol) a...
