Embodiment Construction

[0034] In the embodiment of the present invention, the method of selecting a service for compression processing by comprehensively considering the priority of the service and the compressible bandwidth of the service, taking into account the priority of the user and the quality of service to select the compressed service, while effectively alleviating network communication congestion, as much as possible Guarantee the quality of service for high-priority users and services. The embodiment of the present invention uses WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access) network or TD-SCDMA (Time Division Synchronous Code Division Multiple Access, time division synchronous code division multiple access) and other 3G (3rd Generation, first The third generation) mobile communication system is taken as an example to illustrate the congestion control technical solution provided by the embodiment of the present invention.

Abstract

The invention relates to the field of resource management of wireless network communication, particularly a managing and controlling technology for mitigating network communication congestion. The invention further comprises a congestion controlling method comprising the following steps: switching off the admission control to a newly accessed user when a system is judged to be congested according to uplink received total wideband power (RTWP) and downlink code channel transmit power (TCP); and selecting a service to be compressed according to the compressible bandwidth of each service and comprehensive priority level, and compressing the service selected to be compressed. The invention further provides a congestion control device. As the invention integrates the comprehensive priority level of a service and the compressible bandwidth of the service to select a service to be compressed, compression targets are selected reasonably.

Description

technical field [0001] The invention relates to the field of management of wireless network communication resources, in particular to a management control technology for alleviating network communication congestion. Background technique [0002] In a code division multiple access mobile communication system, when there are too many access users, the system resources will be strained, the load will be overloaded, and the network will be congested. At this time, it is necessary to adopt congestion control, compress the bandwidth occupied by users, release the bandwidth of some services, and reduce the system load to a normal level as soon as possible to relieve congestion. [0003] Such as figure 1 As shown, in the prior art, the functional modules performing congestion control on the RNC (Radio Network Controller, radio network controller) side include: a measurement module 101, a judgment module 102, a congestion control execution module 103, and an overload protection modu...
