Embodiment
Fig. 1 is the flow chart of the method for sharing base band resource pool between cells of the present invention, and as shown in Figure 1, the inventive method may further comprise the steps:
Step 100: the code channel of measuring in the judgement cycle on the auxilliary carrier wave takies situation.
We know that code channel is for a long time occupied, show that the traffic load on present this auxilliary carrier wave is more, and code channel are after a little while occupied, shows that traffic load is lighter.In TD-SCDMA systematic function management, take situation for code channel and had following measurements: up sign indicating number resource sum and take number, and descending sign indicating number resource sum with take number.
Further, because the TD-SCDMA system business, therefore downlink traffic, preferably, can be selected to adopt descending sign indicating number resource sum and take number to take situation as code channel more than or equal to upstream traffic usually.
Do not need to monitor all the time and adjust because dynamic resource is adjusted function, get final product and only need carry out the periodicity judgement.Therefore, this step is in the default judgement cycle, is to obtain above-mentioned measured value in 30 seconds by sampling repeatedly as the employing cycle, and get wherein maximum as the auxilliary carrier wave sign indicating number resource occupation number in the judgement cycle, obtain remaining code channel number with should auxilliary total code channel number of carrier wave deducting carrier wave sign indicating number resource occupation number.
Step 101: whether the residue code channel on the auxilliary carrier wave that judgement is measured is less than predetermined threshold value, if enter step 102; Otherwise enter step 103.
According to the residue code channel number that obtains in the step 100,, then enter step 102 if the residue code channel on the auxilliary carrier wave, then shows high and approaching the taking of the code channel occupancy on all carrier waves in this sub-district less than predetermined threshold value;
If the residue code channel on the auxilliary carrier wave is not less than predetermined threshold value, show then on the carrier wave in this sub-district that the code channel occupancy is very low and idle carrier wave is arranged, then can idle carrier wave not carried out any processing, enter step 103.Further, residue code channel on auxilliary carrier wave is not less than under the situation of predetermined threshold value, if available code channel number on the fully vacant and auxilliary carrier wave of lowest priority of auxilliary carrier wave is arranged more than or equal to predetermined threshold value, in order to economize on resources better, RNC can instruct and enter step 103 behind the idle carrier wave of deletion.
In this step, predetermined threshold value can be according to the user's custom or the professional custom in zone (or sub-district), and test decides by experiment, such as changing violent zone for telephone traffic, threshold value can change zone slowly for telephone traffic more greatly, and threshold value can be littler.
Step 102:RNC instruction increases auxilliary carrier wave.
Fig. 2 is that the present invention issues the schematic flow sheet that cell re-configuration is put auxilliary carrier wave, as shown in Figure 2, RNC can send to base station node B by the instruction that the cell re-configuration request of putting (Cell Reconfiguration Request) will increase/delete carrier wave, base station node B is reshuffled premature beat according to instruction, the specific implementation process belongs to technology as well known to those skilled in the art, and specific implementation method and the present invention are irrelevant, therefore, are not described in detail here.
Step 103: process ends.
By the inventive method, take the dynamic adjustment that situation has realized base station resource according to the code channel on the auxilliary carrier wave, make in two places that exist traffic to migrate, satisfied the resource requirement of sub-district with telephone traffic demand; Further, when telephone traffic was low, the deletion of the idling-resource that each place is existed was saved because the wasting of resources that the processing resource is brought, and has been improved resource utilization greatly.
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in more detail.
Fig. 3 is the flow chart of the embodiment of sharing base band resource pool between cells of the present invention, as shown in Figure 3, supposes that the default judgement cycle has timer to realize, promptly when timer expiry, enters the decision process process, and specific implementation may further comprise the steps:
Step 300: judge whether preset timer is overtime, enters step 301 when overtime, otherwise return step 300.
Step 301: the code channel of measuring in the judgement cycle on the auxilliary carrier wave takies situation.
We know that code channel is for a long time occupied, show that the traffic load on present this auxilliary carrier wave is more, and code channel are after a little while occupied, shows that traffic load is lighter.In TD-SCDMA systematic function management, take situation for code channel and had following measurements: up sign indicating number resource sum and distribute number, and descending sign indicating number resource sum and distribution number.
Further, because the TD-SCDMA system business, therefore downlink traffic, preferably, can be selected to adopt descending sign indicating number resource sum and take number to take situation as code channel more than or equal to upstream traffic usually.
Do not need to monitor all the time and adjust because dynamic resource is adjusted function, get final product and only need carry out the periodicity judgement.Therefore, this step is in the default judgement cycle, is to obtain above-mentioned measured value in 30 seconds by sampling repeatedly as the employing cycle, and get wherein maximum as the auxilliary carrier wave sign indicating number resource occupation number in the judgement cycle, obtain remaining code channel number with should auxilliary total code channel number of carrier wave deducting carrier wave sign indicating number resource occupation number.
Step 302: judge whether that available code channel number on the fully vacant and auxilliary carrier wave of lowest priority of auxilliary carrier wave is more than or equal to predetermined threshold value? if then enter step 303; Otherwise enter step 304.
Available code channel number as auxilliary carrier wave on the vacant fully and auxilliary carrier wave of lowest priority is more than or equal to predetermined threshold value, and then showing has idle auxilliary carrier wave; Otherwise need further judge whether to need to increase auxilliary carrier wave.
Step 303:RNC deletes vacant auxilliary carrier wave, enters step 306 afterwards.
The specific implementation of deleting vacant auxilliary carrier wave can realize by flow process shown in Figure 2.
Step 304: is the residue code channel number in the sub-district on the auxilliary carrier wave of lowest priority less than predetermined threshold value? if then enter step 305; Otherwise enter step 306.
Residue code channel number in the sub-district on the auxilliary carrier wave of lowest priority shows high and approaching the taking of the code channel occupancy on all carrier waves in this sub-district less than predetermined threshold value.
Step 305:RNC increases auxilliary carrier wave.The specific implementation that increases auxilliary carrier wave can realize by flow process shown in Figure 2.
Step 306: timer resets.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of being done, be equal to and replace and improvement etc., all should be included within protection scope of the present invention.
