example 1

[0120] Example 1: User forward QOS service flow acceptance process:

[0121] The forward wireless bandwidth information collected by the base station system includes: ThruptF=2000kbps, IdleT=0.75; AllocatedBWf=2000kbps already allocated; calculate the current maximum available forward bandwidth MaxBWf of the base station system is 2133.3kbps, then the current forward remaining bandwidth is 133.3 kbps;

[0122] If the priority of the forward QOS service flow requested this time is:

[0123] BandReqF0 = 200kbps;

[0124] BandReqF1 = 150kbps;

[0125] BandReqF2 = 120kbps;

[0126] Therefore, the judgment result of whether to accept the forward QOS service flow of the new user in this application is as follows:

[0127] BandReqF0 and BandReqF1 cannot be accepted;

[0128] BandReqF2 can be accepted,

[0129] Therefore, the user's forward QOS service flow is accepted successfully.

example 2

[0130] Example 2: User reverse QOS service flow acceptance process:

[0131]The forward wireless bandwidth information collected by the base station system includes: ThruptR=1239kbps, RABIdleRatio=0.56, BrFactor=0.8, allocated AllocatedBWr=1600kbps; the current maximum available reverse bandwidth of the base station system MaxBWr=1770kbps is calculated; then the current forward remaining The bandwidth is 170kbps;

[0132] If the reverse QOS service flow priority of this application is:

[0133] BandReqR0 = 200kbps;

[0134] BandReqR1 = 150kbps;

[0135] BandReqR2 = 120kbps;

[0136] Therefore, the result of judging whether to accept the reverse QOS service flow of new users in this application is as follows:

[0137] BandReqR0 cannot be accepted;

[0138] BandReqR1 can be accepted;

[0139] Therefore, the reverse QOS service flow of the user is accepted successfully.

example 3

[0140] Example 3: The adjustment process of QOS reverse service flow priority when the wireless signal quality changes:

[0141] The reverse wireless bandwidth information collected by the base station system includes: ThruptR=1102kbps, RABIdleRatio=0.56, BrFactor=0.8; already allocated AllocatedBWr=1600kbps; then the current maximum available reverse bandwidth of the base station system MaxBWr=1575kbps;

[0142] MaxBWr

[0143] Compared with the prior art, the present invention realizes the dynamic acceptance of the forward and reverse service flows of the QOS users of the base station system. Collect the forward throughput ThruptF and time slot occupancy IdleT periodically reported by th...

Abstract

The invention relates to an admission control method for user access in a base station system, comprising the following steps that: when receiving a service request of quality of service (QOS) of a user, the base station system acquires the current maximum available wireless bandwidth of a base station system in real time, acquires the current wireless bandwidth of the current distributed service flow of the base station system and obtains the current residual wireless bandwidth; and the base station system combines the QOS service flow grade of the user accessed into the base station system and the QOS service flow grade of the user of the current request according to the residual wireless bandwidth to carry out admission judgment on the QOS service flow of the user request. Correspondingly, the invention also provides an admission control device for user access in the base station system. The device comprises a service request receiving module, a residual wireless bandwidth acquiring module and an admission judging module. The method and the device determine whether the service flow is admitted by acquiring real-time wireless bandwidth information so as to ensure to provide the needed QOS service.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to an admission control method and device for user access in a base station system. Background technique [0002] After the development of wireless communication technology to the third-generation mobile communication technology (3rd-generation, 3G), voice services and low-speed data services in the second-generation mobile communication technology (2nd Generation, 2G) period developed into wireless broadband data services . [0003] 3G can provide users with more and more services, including ordinary user upload and download services, audio and video quality of service (Quality of Service, QOS) services based on Internet Protocol (Internet Protocol, IP) (such as: video Telephone (Video Telephone, VT), VoIP (Voice overIP, VOIP) service), and QCHAT multicast service, etc. If these services are realized, the base station system should be able to provide the re...
