Method for allocating channel resources

Abstract

The invention discloses a method for allocating channel resources. When allocating channel resource identifiers for newly accessed terminals, the latest allocated channel resource identifiers are firstly determined, and then the idle channel resource identifiers are sequentially searched from the latest allocated channel resource identifiers. ; If found, assign the found channel resource identifier to the current access terminal, set the channel resource identifier assigned by the current access terminal to the recently allocated channel resource identifier, and set the status of the channel resource identifier as occupied; if not found, perform End processing. By using the method, idle channel resources are fully utilized, and the probability of conflict between channel resources allocated for new access terminals and channel resources released by on-hook users is reduced, thereby improving the impact resistance of the system.

Description

technical field [0001] The invention relates to channel resource allocation technology of a wireless access system, in particular to a method for allocating channel resources. Background technique [0002] With the development of wireless communication technology, the service capability provided by WCDMA (Wideband Code Division Multiple Access) system is far greater than that provided by GSM (Global System for Mobile Communications). WCDMA adopts code division multiple access technology, and the number of channels provided by its NodeB (base station of the third generation mobile communication system) is far more than that provided by the base station of the GSM system. In order to fully reflect the superiority of the WCDMA system and make full use of channel resources, it is necessary to manage channel resources effectively, especially in hotspot areas, when a large number of users access and hang up, it is necessary to ensure the utilization of channel resources, so as to ...

AI Technical Summary

Problems solved by technology

However, since the ID resource allocated by NodeB is often used by multiple modules at the same time, when the user hangs up and releases the ID resource, it cannot be guaranteed that the same ID resource will be released in multiple modules at the same time

For example, the FPID (1, 2) allocated by NodeB to user A is used by the FP module, decoding module, and encoding module at the same time. Therefore, when user A hangs up, it cannot be guaranteed that the FPID occupied by user A will be deleted in these three modules at the same time. When the FPID (1, 2) occupied by user A has not been deleted on any of the three modules, if user C accesses, NodeB will assign FPID (1, 2) to user C at this time

In this way, because FPID (1, 2) has not been completely deleted in the three modules, it will inevitably cause user C to fail to access

The defect of the prior art is: when there are still idle ID resources in the NodeB, the system cannot allocate appropriate ID resources for new access terminals due to the above conflict problem

This technology increases the complexity of the system for user access processing

In hotspot areas, when a large number of users access or hang up, the allocation of ID resources for a large number of new users needs to be tried many times, which seriously reduces the processing efficiency of the system. The impact resistance has been significantly improved
