A PDCH channel configuration method and device

Abstract

The present invention provides a PDCH channel configuration method and device. The method includes: calculating the single-slot theoretical rate of the cell according to the single-channel rate of the cell and the high coding ratio corresponding to the single-channel rate; Carry out quantitative evaluation of the service perception level to obtain quantitative evaluation parameters; determine the single time slot of the cell according to the first correspondence between the pre-statistical cell traffic value, time delay and single-user single-slot rate, and the quantitative evaluation parameters Demand rate: Calculate the theoretical channel value of the cell according to the multi-slot capability parameters of the terminals in the cell and the number of concurrent terminals within the preset time period; calculate the theoretical channel value of the cell based on the theoretical single-slot rate, single-slot demand rate, and theoretical channel value of the cell , calculating the required channel value of the cell; performing channel configuration of the cell according to the current channel value of the cell and the required channel value. The present invention formulates a PDCH configuration scheme according to the actual situation of the cell, reflecting user perception.

Description

technical field [0001] The present invention relates to the wireless field, in particular to a PDCH channel configuration method and device. Background technique [0002] Currently, there are two methods for configuring PDCH channels in the GSM data service system: [0003] 1. Combining the statistical analysis of the PDCH multiplexing degree of the GSM data service cell and the increase or decrease of the PDCH channel in the cell coverage scenario, that is, when the multiplexing value of the wireless statistical index of the cell is high, the PDCH channel configuration is appropriately increased, otherwise, the PDCH channel is reduced. [0004] 2. By collecting statistical indicators related to wireless data services, combined with some theoretical models (such as the Campbell model) and Irish B table for calculation, realize PDCH channel configuration. [0005] The existing methods are all based on wireless statistics. The problem is that OMC’s statistics on channel occup...

Problems solved by technology

[0005] The existing methods are all based on wireless statistics. The problem is that OMC’s statistics on channel occupancy are based on the sampling of certain counters. The sampling period is usually 5 to 10 seconds, which is similar to the allocation granularity of PDCH wireless data packets of 20 ms. In contrast, it is completely unable to reflect the real concurrent data user's request for the channel, and the calculated PDCH channel will seriously affect the user's data service experience.
