Description
The present invention relates to cdma base station system, relate in particular to method for distributing calling resource in the cdma base station system.
Because the CDMA mobile communcations system is at the cellular system that all is superior to other aspect power system capacity and the reduction radiation far away, so cdma system has all obtained application more and more widely all over the world.For mobile communcations system, the quality of voice quality directly has influence on the performance of this system, so how to set up the speech of high definition, is one of key technology of cdma system.In cdma base station system, set up when calling out and to use a lot of resources, comprise selector/vocoder, Channel Elements and Traffic Channel etc., so must before call setup, be the various resources of call distribution, and determine the relevant parameter of each resource, begin frame biasing, operating frequency of sampling time, Traffic Channel etc. as every frame of selector/vocoder, the time delay of voice played important effect when the method for salary distribution of these resources had directly influenced calling ratio of success and conversation in cdma base station system.In existing C DMA base station system, resource allocation during for call setup is not consider any factor, do not handle or optimization process through any allocation strategy, only be random selector vocoder, Channel Elements and Traffic Channel to be carried out resource allocation, do like this and can produce many beyond thought consequences, the conversation time delay is big in the time of as calling, and call successful rate is low etc., has greatly influenced the stability and the operating efficiency of system.And cause the waste of resource and the increase of system cost.
The purpose of this invention is to provide a kind of effective shortening conversation time delay, improve call successful rate and reduce the base station system method for distributing calling resource of system cost, shortcomings such as resource arbitrarily distributes the time delay of being brought big when overcoming existing call out, and call successful rate is low.
To achieve these goals, the present invention proposes a kind of cdma base station system method for distributing calling resource, it is characterized in that may further comprise the steps: sub-district, travelling carriage place is determined in 101 positions of calling out according to Mobile Origination, and obtains the relevant parameter of sub-district; 102 select a carrier frequency that load is minimum; 103 judge whether idle business channel is arranged under this carrier frequency, if there is not available idle traffic letter under this carrier frequency
The road then changes 113, otherwise continues; 104 every frames according to vocoder unit begin sampling time and Channel Elements can with the frame biasing judged whether
Available frame biasing if do not have, is then changeed 113, otherwise is continued; 105 choose an available frame biasing; 106 judge whether to also have idle vocoder unit to distribute, if the vocoder of no available free time
The unit then changes 113, otherwise continues; 107 judge whether to also have available channel board, if no available channel board then changes 113, otherwise continue; 108 judge whether to also have idle Channel Elements to distribute, if the channel list of no available free time
Unit then changes 113, otherwise continues; 109 distribute the vocoder unit of choosing; 110 distribute an available idle business channel; 111 Channel Elementss according to an available free time of frame offset allocations of choosing; 112 resource allocations finish; 113 judge whether to also have available carrier frequency, if do not have, and then this time resource allocation failure, otherwise change 114; 114 select another frequency, change 103.
Adopt the method for the invention, by the every frame of vocoder unit being begun the Optimal Control of sampling time and Channel Elements frame biasing, can be effectively within the specific limits with the control of conversation time delay, and realized load sharing at each carrier frequency of sub-district, reduce the interference between the user, improved communication effect.
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is cdma base station system call resources allocation flow figure proposed by the invention;
Resource allocation methods when flow chart shown in Figure 1 is understood callings of the present invention in the method, has been stipulated the coding zero hour of each vocoder and has decoded all to immobilize the zero hour.The due in of the x time of forward traffic channel frame and reverse traffic channel frame is determined by the frame biasing of Traffic Channel, and the biasing of the frame of each Channel Elements is unfixing.A plurality of Channel Elementss allow to use identical frame biasing on a channel board, but can not surpass a upper limit.Owing between base station controller (BSC, Base Station Controller) and the base station transceiver (BTS) propagation delay time is arranged, the forward traffic channel frame behind the vocoder coding passes to moment of Channel Elements should be early than the x time of forward traffic channel frame; Equally, the reverse traffic channel frame arrive the moment of passing to vocoder behind the Channel Elements should be early than the decoding zero hour of vocoder.So, can select suitable frame biasing, reverse time delay minimum before making for Channel Elements according to coding zero hour of each vocoder and decoding zero hour.At first sub-district, travelling carriage place is determined in the position of calling out according to Mobile Origination, and obtain the relevant parameter of sub-district simultaneously, according to calling out the sub-district of being initiated, inquire about the travelling carriage call case of having initiated under each carrier frequency of this sub-district, therefrom select one to call out minimum carrier frequency as the callwork carrier frequency according to the load sharing principle; Judge then whether idle business channel is arranged under this carrier frequency, if do not have available idle business channel under this carrier frequency, then again according to the load sharing principle, select another frequency, if idle Traffic Channel is arranged, according to every frame of vocoder unit begin sampling time and Channel Elements can with the frame biasing judge whether available frame biasing, if exist, choose an available frame biasing, otherwise, the frequency that more renews, so that the travelling carriage of each carrier frequency work is average as far as possible, promptly realize the load sharing between each carrier frequency of sub-district, can avoid in multi-carrier frequency system like this, all users take a frequency, and other frequency users numbers seldom; Next the repeat circuit that distributes by switch (MSC Mobile Switch Center), the selector vocoder subsystem that finds repeat circuit to connect, in this subsystem, select the selector vocoder of a free time, if the vocoder unit of no available free time, then change frequency, because fix the zero hour of the encoding and decoding of each selector vocoder, so after having determined the selector vocoder, the preceding reverse encoding and decoding of this time calling have just been determined the zero hour; Biasing judges whether to have in addition the channel board of available channel unit according to the frame that obtained then again, distributes if find then, if the Channel Elements of no available free time then changes frequency; Preserve each resource operating position at last, be changed to above resource of distributing (comprising Traffic Channel, vocoder unit, Channel Elements) state busy, can not distribute when representing sub-distribution down, resource allocation can be understood resource allocation conditions after making, carry out suitable distribution, thereby improved the speed of call setup.
The method of the invention, not only can allow system real-time know resource operating position at any one time, thereby the most reasonably distribute, improved calling ratio of success; And by the every frame of vocoder unit being begun the Optimal Control of sampling time and Channel Elements frame biasing, can be effectively within the specific limits with the control of conversation time delay, realized load sharing, reduced the interference between the user, improved the efficient of call through at each carrier frequency of sub-district.
