Problems solved by technology

[0007] 1. The overload of the base station causes a large number of messages to be discarded, and the service success rate indicators related to paging of the entire system drop sharply
[0008] 2. The paging time is extended, resulting in an increase in the call connection delay in the system as a whole
[0009] 3. Messages are congested or discarded, resulting in repeated retransmission of paging messages, reducing the processing efficiency of the entire system

Embodiment Construction

[0059] According to the CDMA protocol, the code channel that can only be assigned to the paging channel is W 1 64 to W 7 64 . Since each available carrier frequency of the CDMA system needs to configure at least one paging channel, so W 1 64 The code channel is fixed as the paging channel, only the code channel is W 2 64 to W 7 64 Participate in the dynamic adjustment of channels, and these channels can be used as paging channels or traffic channels according to the adjustments. In order to reduce the complexity of these code channel conversions, it is proposed to impose the following constraints on the system Walsh code channel allocation method: W 2 64 to W 7 64 Code lane final distribution principle. i.e. W 2 64 to W 7 64 When the code channel is used as a traffic channel, the system will allocate W one by one only when other traffic channels are occupied. 7 64 , W 6 64 , W 5 64 , W 4 64 , W 3 64 , W 2 64 Used as a traffic channel.

Abstract

This invention relates to a method for adaptively adusting radio empty paging channels in the CDMA system including: BTS monitors the load of the paging channels to report the statistic state information of the paging channels, BSC carries out the adjustment judgment of the paging channels, if the result needs to reduce or increase numbers of the paging channels, then the BSC decreases or adds one to the current carrier paging channel numbers, BSC sends set information of local area to BTS to modify the carries configuration corresponding to BTS then to feed back the set response information to BSC, which rceives the response information to start up the regulation-protection timer to end the adjustment process of this paging channel after the timer is over the time.

Description

technical field [0001] The invention belongs to the technical field of CDMA system communication, and in particular relates to a wireless air interface paging channel adjustment method. Background technique [0002] CDMA2000 1X system architecture such as figure 1 As shown, wherein, BTS is a base station transceiver (Base Station Transceiver), BSC / PCF is a base station controller / packet control function (Base Station Controller / Packet Control Function), MSC / VLR is a mobile exchange / visiting location register (Mobile Switching Center / VisitorLocation Register), PDSN / FA is Packet Data Serving Node / Foreign Agent, SMC is Short Message Center, HLR / AC is Home Location Register / Authentication Center (Home Location Register) Register / Authentication Center), HA is HomeAgent, RADIUS is Remote Authentication Dial In User Service Server, RADIUS is mainly used for authentication, authorization and billing. [0003] In the CDMA 2000 1X system, the forward common channel generally includ...
