Distribution method of data traffic wireless channel in GPRS/EDGE network

Abstract

The invention discloses a distribution method of data business wireless channel in a GPRS/EDGE network. The invention is aimed at making the number of reasonable data business wireless channel satisfy the lowest request of user for quality of service. The method comprises following steps: establishing a TBF/ETBF timelag rejecting queuing model in the GPRS/EDGE network; solving importing parameter of the TBF/ETBF timelag rejecting queuing model in the GPRS/EDGE network; making use of the TBF/ETBF timelag rejecting queuing model to calculate the number of grouping domain data business windows in the actual EDGE/GPRS network according to a data business flow of user in the network and a data business service quality target; and converting the number of data business windows to the number of the wireless channels in the GPRS/EDGE network. The TBF/ETBF in the GPRS/EDGE network is considered as a fundamental unit of carrying data in the network. Because the TBF/ETBF is fundamental data of a data link layer of data communication, calculation accuracy is greatly improved.

Description

technical field [0001] The present invention relates to a technology for allocating wireless channel of packet domain data service in mobile communication network, more specifically, it relates to a method for allocating wireless channel of data communication service in GPRS / EDGE network. Background technique [0002] The General Packet Radio Service (referred to as GPRS) based on the GSM communication system can provide packet wireless data communication services. It provides continuous Internet connection for mobile terminal users by bundling several time slots for use. GPRS can support a data transmission rate above 100kbps, and can provide multimedia services such as video and interaction. [0003] With the opening of GPRS network and business and after several years of development, the GPRS Extended Data Environment (abbreviated as EDGE technology) also based on the GSM system standard has also been put into the GSM system. EDGE is an evolution technology of GPRS and a...

Problems solved by technology

There are some problems in the use of these three types of methods in the actual network: the first two types are iterative processes, you need to assume the number of channels first, and then compare whether the requirements are met, so it is inconvenient to look at the picture or calculate, and there is no Considering the user's perception of the service quality of the data service; and the third category needs to count the networ
