Overload control method and device for control channel of wireless communication system

Abstract

The invention discloses an overload control method and a device of controlling channel in a wireless communication system, which is used in overload control for sector message. The method includes: an overload judgment processing step, in which prior cell control channel judges whether the overall length of the sector message exceeds maximum message length borne by the control channel; if exceed,select common-frequency neighboring cell configuration message to construct a first forward queue in the sector message, according to common-frequency neighboring cell configuration message priority principle and send out the sector message according to the first forward queue. The invention realizes reasonable control and selection for the sector message according to certain overload control algorithm, when the sector message to be sent by AN on the control channel exceeds the control channel bearing capability, and AT can acquire the sector configuration message of the prior cell AN as muchas possible.

Description

A method and device for overload control of a control channel in a wireless communication system technical field The present invention relates to a wireless communication system, in particular to a method and device for overload control of a control channel in the wireless communication system. Background technique CDMA20001XEVDO technology is a branch of the CDMA2000 standard series, which provides support for high-speed wireless data services. It can be networked together with the CDMA20001X network that provides voice services and low-speed data services, and uses bandwidths at different frequencies. CDMA is (CodeDivisionMultipleAccess) code division multiple access, EVDO is (EvolutionDataOnly / EvolutionDataOptimized, evolution, optimized data service). The forward channel of CDMA20001XEVDO adopts the time division method, and all users in a sector share the forward time slot of the sector. The control channel is the common channel of all users in the sector, and each...

Problems solved by technology

The length of the sector message increases rapidly with the increase of the neighbor cell configuration message of the current cell. Due to the limited forward time slot of the control channel, it will not be possible to send too long sector messages.

According to the current processing method of the system, the first is to discard the sector message, and this will cause the access terminal AT to be unable to update the information of the base station access network AN in time; The problem with this processing method is that the important same-frequency neighbor configuration message may be discarded, and the less important inter-frequency neighbor configuration message is sent
