Problems solved by technology

[0007] It can be seen from the above that the biggest disadvantage of the existing method for statically allocating channel code resources is that it cannot maximize the utilization efficiency of channel code resources, thereby limiting system capacity and reducing user satisfaction, especially call quality.

Embodiment Construction

[0029] The essence of the present invention is that on the basis of statically reserved channel codes, the system monitors the use of channel code resources reserved for various channels in the cell at any time. If the system detects that some channel code resources are excessive and some If the channel code resources are insufficient, the system temporarily reallocates part of the code resources of the channels with excess code resources to the channels with insufficient code resources through a certain method, so as to improve the system capacity and communication quality while making full use of the code resources.

[0030] The code resource sharing of DCH and DSCH is taken as an example below, and the present invention will be further described in detail in conjunction with the accompanying drawings.

[0031] figure 2 It is a flowchart of an embodiment of the method of the present invention. figure 2 The above-described embodiments illustrate the sharing of channel code...

Abstract

The method includes following steps: holding some channel codes for various channels of requesting resources of shared codes; monitoring condition of using channel codes in said each channel; evaluating condition of using channel codes monitored; based on evaluated result, assigning channel codes possible to be redistributed in channel, which has superfluous resources, to channels, which is deficient in resources; the method optimizes distribution of channel resources so as to increase number of accessible users or decrease call loss as well as increase average rate of transmission of data and performances of system.

Description

technical field [0001] The invention relates to a mobile communication system, especially a method for sharing system resources. Background technique [0002] In a mobile communication system, there are generally multiple channels used to transmit user data, and rational use of these channels is an important means to effectively use system resources. For example, in a wideband code division multiple access (WCDMA) mobile communication system, there are mainly three channels in the downlink direction that can be used to transmit user data, namely a dedicated channel (DCH), a forward access channel (FACH) and a shared channel (DSCH). ). The above-mentioned channels are distinguished by channel codes, that is to say, the channels in the WCDMA system correspond to different channel codes, and the size of the channel code determines the bandwidth of the channel. Allocating a channel with a certain bandwidth to a specific user is actually allocating a channel code of a specific ...
