For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with specific embodiment, and with reference to accompanying drawing, the present invention is described in more detail.
Fig. 1 is the flow chart of mobile communication base station of the present invention Channel Elements Dynamic Configuration.The method comprises the following steps:
S101, by the CE license centralized management in network, form CE license pond.
CE is Channel Elements, and the use of each CE needs an authorization code of Qualcomm (license), is called CE license.So being mainly the content (code word) to authorization code, centralized management CE license manages concentratedly.Existing authorization code is scattered in each base station, there is no unified allocation of resources, management.The present invention, by the authorization code centralized management, the allotment that disperse, is referred to as " CE license pond " here, is the precondition of follow-up flow process dynamic-configuration.
The content of CE license pond centralized management can comprise: license code word, affiliated BSCID(Base Station Controller Identity base station controller sign), affiliated BTSID(Base Transceiver Station Identity Base Station Identification) and the term of validity etc.For example:
" license code word " represents authorization code particular content, letter or number etc., consists of.In existing cdma communication, only have the Channel Elements that has configured license just can use, the Channel Elements that does not configure license be physically exist but can not be used;
" affiliated BSCID " refers to which base station controller CE license is configured in;
" affiliated BTSID " refers to which base station CE license is configured in;
" term of validity " refers to the useful life of CE license.
S102, according to the historical same period, with period traffic data, or import existing each base station CElicense configuration, CE license and the number of configurating base station.
Which authorization code existing each base station CE license configuration has configured to base station in fact with exactlying, direct CElicense and the number that carrys out configurating base station according to existing CE license and number.
According to the historical same period, with period traffic data (base station call amount), under the condition of GOS=2%, inquiry ERLANG B can obtain required Channel Elements number, and each Channel Elements need configure a license, hence one can see that CE license number that each base station need configure.Wherein, GOS(Grade of Service) represent the grade of service, in communication system, conventionally suppose that the percent of call lost or blocking rate are 2%, i.e. GOS=2%.
The CE number that S103, monitoring base station are used, determines CE license number according to CE number.
In real time or the CE number that quasi real time monitoring base station is used.Because the statistics of CE service condition may have a minimum time granularity (as some minutes) in base station management system, monitoring can only can not take situation by Real-Time Monitoring CE based on this time granularity, is referred to as quasi real time.Service condition specifically refers to the number that in base station CE is occupied or be assigned with.CE is by the management of base station baseband processing unit, scheduling, and CE number occupied or that be assigned with can be added up in base station.
S104, judge whether the CE license number using base station is greater than the CElicense number of base station configuration, if so, carry out S105, otherwise, S106 carried out.
S105, increase base station CE license configured number.
The CE license number sum of all base stations configuration should be less than or equal to the number in CE license pond, otherwise need in CE license pond, insert new CE license.
Whether S106, the CE license number that judges base station configuration are greater than (1+m) and are multiplied by the CE license number using base station, if so, carry out S107, otherwise, carry out S108.Wherein, m is more than or equal to the capacity surplus that 0, m represents to tackle bursts of traffic, and this value can be according to actual conditions adjustment.
S107, minimizing base station CE license configured number.
S108, do not adjust the CE license number having configured.
Few to telephone traffic, CE is used less but CE license number is reduced in initial configuration CE license number more base station in base station; High to telephone traffic, CE is used base station many but that base station initial configuration CElicense number is less to increase CE license number.
With an example, illustrate how to adjust the CE license number having configured below.It will be understood by those skilled in the art that described example, just for for example, should not be construed as limitation of the present invention.
Suppose that the base station CE license use number that actual monitoring arrives is X, the CElicense configured number of base station configuration is Y, X<Y< (1+30%) * X.30% value comes from it is generally acknowledged that communication system is when capacity configuration, should have 30% capacity surplus with reply bursts of traffic, and this value can be according to actual conditions adjustment.
If now to have configured CE all occupied in base station for X>Y(, even produce the calling and the handover blocking that because of CE deficiency, cause), need to increase base station configurating channel number, increase CE license number;
If Y>X*130%, thinks that this base station configurating channel number is too much, resources idle, should reduce base station configurating channel number, reduces CE license number.
The present invention realizes different scenes, the CE license time-sharing multiplex of different busy periods, can increase work efficiency and the CE level of resources utilization.
For example, office space traffic on general daytime is busy, and evening, traffic was rare; Residential quarters telephone traffic in general evening is large, and daytime, traffic was rare.If two kinds of suitable time-sharing multiplexs of scene CE license, can improve the CE level of resources utilization.
Again for example, scene traffic on general daytime in campus concentrates on teaching area, campus, educational administration district, evening, traffic concentrated on students' dormitory district, if cover the base station and the base station CE license time-sharing multiplex that covers dormitory area, campus in teaching educational administration district, campus, can improve the CE level of resources utilization.
