Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
The embodiment of the invention provides a kind of method of cell switch determining, can improve the sub-district and switch reasonability, helps reducing erroneous judgement and improves overall signal quality.
The embodiment of the invention can be used in the time-division system, as GSM (Global System for Mobilecommunications, global system for mobile communications) system, TD-SCDMA (Time Delay-Synchronization Code Division Multiple Access, time delay-S-CDMA) system etc.
Below in conjunction with accompanying drawing the embodiment of the invention is described in detail, below a mentioned single channel can be the employed current channel of MS, also can be a certain channel except that current channel, be determined on a case-by-case basis that the embodiment of the invention is the example explanation with current channel.
Referring to Fig. 1, the method flow schematic diagram for the embodiment of the invention one cell switch determining illustrates embodiment of the invention concrete steps;
Step 101: obtain the single channel BEP value of current service cell in the PS territory.
Described BEP value reflection channel quality status, this value hour its logarithm value of stipulating in related protocol more is big more, and the channel quality that then reflects is poor more.
A described single channel can be any single-channel one in PS territory, does not influence the realization of the embodiment of the invention.
Step 102: judge described BEP value greater than the error threshold value.
The error threshold value be in advance rule of thumb with the specific requirement setting, be that channel normally provides PS territory service to can bear the threshold limit value of error code; Accessed BEP value is compared with the error threshold value, if greater than the error threshold value, illustrate that then current quality of channel is lower, MS has the needs of switching cell.
Step 103: select the adjacent area to switch.
After confirming that MS has needing of switching cell, select the adjacent area to switch.
Present embodiment is the switch decision standard with PS territory single channel BEP value, improves the sub-district and switches reasonability, the needs of more realistic use.
Embodiment one has illustrated the disposition when the BEP value is greater than the error threshold value, in actual applications, also exists the BEP value to be not more than the situation of error threshold value, and following examples two specify in conjunction with Fig. 2, and Fig. 2 is the method flow schematic diagram of the embodiment of the invention two:
Embodiment two:
Step 201: obtain the single channel BEP value of current service cell in the PS territory and the descending incoming level value of adjacent area and current service cell.
A described single channel can be any single-channel one in PS territory, does not influence the realization of the embodiment of the invention.
Step 202: whether judge described BEP value greater than the error threshold value,, be not more than and then change step 204 over to greater than then changing step 203 over to.
Preferably, judging that whether described BEP value can time judge to determine greater than the error threshold value through continuous N, all is BEP value during greater than the error threshold value at M court verdict, changes step 203 over to.M is a positive integer, and value can rule of thumb be provided with flexibly, in time adjusts according to channel conditions, and when channel conditions was not good enough, this numerical value can be bigger than normal, to guarantee the reasonability of court verdict.
Step 203: judge that described adjacent area incoming level value whether greater than current service cell incoming level value, is then to change step 205 over to, otherwise changes step 206 over to.
Step 204: judge that the descending incoming level value in adjacent area whether greater than current service cell signal stowed value, is then to change step 205 over to, otherwise changes step 206 over to.
Current service cell signal stowed value is meant the descending incoming level value of current service cell, switches hysteresis and level penalty value three sum.
When the descending incoming level value in adjacent area during greater than current service cell signal stowed value, then change step 205 over to, otherwise illustrate that then current service cell is the best sub-district of signal stowed value, there is not necessity of switching, change step 206 over to;
The level penalty value and switch hysteresis be in advance rule of thumb with the specific requirement setting, can change flexibly;
The judgement of signal stowed value can be confirmed to improve the accuracy of judgement equally through N continuous time judgement, and N is a positive integer.
Step 205: select an adjacent area to switch.
Step 206: finish the switch decision flow process.
When present embodiment is not more than the error threshold value in the BEP value, adopt the descending incoming level value in adjacent area to judge the cell signal quality, and under different mode, the concrete parameter of the descending incoming level value in adjacent area is different, following examples three and embodiment four fundamental rules are example with the gsm system, respectively under non-DTM pattern and DTM pattern explanation BEP value greater than with the handling process that is not more than the error threshold value.
Embodiment three:
In conjunction with Fig. 3, be the method flow schematic diagram of the embodiment of the invention three cell switch determinings, with non-DTM pattern be example explanation BEP value greater than with the handling process that is not more than two kinds of situations of error threshold value.
Step 301: receive the measurement report that MS reports.
The value that MS reports comprises different content under different mode.With the gsm system is example, under non-DTM pattern, reception be on the current channel in PS territory/the descending incoming level value of descending BEP value and PS territory current service cell and adjacent area; Wherein, the descending incoming level value of PS territory current service cell and adjacent area periodically reports by descending level measurement report, and the BEP value of the up every channel in PS territory is at BTS (Base Transceiver Station, base transceiver station) locates to report after the measurement, the BEP value of the descending every channel in PS territory is by Ctrl Ack (Control ACKnowledge signal, the control response message) incidentally arrives BSC (Base station controller, base station controller).
Step 302: the measurement report that is received is carried out interpolation and Filtering Processing.
Interpolation processing is meant when having the losing of measurement report intermediate value in the process of transfer of data, in order to guarantee the continuity of measurement report, and the value of losing estimated, fills up the value of losing, and makes measurement report continuous, for follow-up Filtering Processing.
When going out the loss situation of present worth, the non-constant of current channel quality is described, so interpolation adopts the worst-case value interpolation, the number of the measurement report of even losing is lost the measurement report number less than the maximum that allows, the measurement report values assignment that then will lose is a worst-case value.
Filtering Processing is the accuracy for the raising switch decision, and the measurement report in a period of time is handled, and adopts average RCV=∑
1 LfilterRCV
k/ L
FilterHandle, wherein L
FilterBe filter length, RCV
kFor BEP value and the descending incoming level value that reports in the measurement report, passed through interpolation processing in case of necessity.
Step 303: start switch decision.
Can set starter and periodically start switch decision voluntarily, other Starting mode do not influence the realization of the embodiment of the invention yet.
Step 304: obtain the single channel BEP value of current service cell in the PS territory.
Obtain in the PS territory a single channel BEP value promptly on the current channel in the PS territory in the measurement report after interpolation and Filtering Processing/descending BEP value.
A described single channel can be any single-channel one in PS territory, does not influence the realization of the embodiment of the invention.
Step 305: judge that the BEP value whether greater than the error threshold value, is then to change step 306 over to, otherwise changes step 308 over to.
When judging BEP value that step 304 obtains greater than the error threshold value, illustrate that then current quality of channel is lower, MS has the needs of switching cell, changes step 306 over to; If the BEP value is not more than the error threshold value, then change step 308 over to.
Step 306: judge whether that continuous N time judgement BEP value greater than the error threshold value, is then to change step 307 over to, otherwise changes step 304 over to.
M time value can be adjusted immediately according to channel conditions, and when channel conditions was not good enough, this numerical value can be bigger than normal, and it is excessive influenced by channel conditions with the BEP value of avoiding obtaining; After continuous N time determines that the BEP value obtained is greater than the error threshold value, change step 307 over to; Judge that number of times does not arrive M time, then change step 304 over to, obtain the BEP value again and rejudge.
Step 307: judge whether to exist the adjacent area of PS territory incoming level value, be then to change step 311 over to, otherwise change step 312 over to greater than current service cell incoming level value.
Step 308: the descending incoming level value of obtaining PS territory current service cell and adjacent area.
The descending incoming level value of PS territory current service cell of obtaining and adjacent area is the descending incoming level value in the measurement report after step 302 interpolation and Filtering Processing that receives in the step 301.
Step 309: judge that the descending incoming level value in adjacent area, PS territory whether greater than the descending incoming level value of PS territory current service cell, switching hysteresis and level penalty value three sum, is then to change step 310 over to, otherwise changes step 312 over to.
The level penalty value is meant to reducing the additional flexible change value of influence that the channel quality fluctuation causes, for example: because of certain reason, once the A sub-district of associating switches to the situation of B sub-district failure, and additional penalty value in the B sub-district then is so that the A sub-district no longer preferentially selects the B sub-district to switch.
When the switching of carrying out based on level, the incoming level of adjacent area must exceed the certain grade of incoming level of this Serving cell, could switch; Switch the level value that hysteresis just is meant certain grade that this exceeds.This value can rule of thumb be provided with in advance flexibly, decides on concrete sub-district.The descending incoming level value in adjacent area, PS territory illustrates then that greater than the descending incoming level value of PS territory current service cell, switching hysteresis and level penalty value three sum the adjacent area possesses switching condition.
Step 310: whether the N continuous time descending incoming level value in judgement adjacent area, PS territory is greater than the descending incoming level value of PS territory current service cell, switching hysteresis and level penalty value three sum,, be then to change step 311 over to, otherwise change step 308 over to.
Equally, based on the accidental influence of avoiding channel fluctuation to bring, the judgement of step 309 also need be inferior repeatedly to improve the numerical value accuracy through N continuous, and N time implication can rule of thumb be provided with in advance flexibly with aforementioned M time.
Step 311: select an adjacent area to switch.Step 312: finish the switch decision process.
On the BEP value of obtaining because of step 304 among the embodiment three certain individual one by one single channel for the PS territory of reception in the step 301/descending BEP value, with a single channel BEP value is that standard is carried out switch decision, then having changed with the average BEP value of multichannel is Current situation of standards, improve the sub-district and switch reasonability, reduced and switched erroneous judgement.

In conjunction with Fig. 4, be the method flow schematic diagram of the embodiment of the invention four cell switch determinings, with the DTM pattern be example explanation BEP value greater than with the handling process that is not more than two kinds of situations of error threshold value.
Step 401: receive the measurement report that reports;
Under the DTM of gsm system pattern, the particular content of measurement report is on the current channel in PS territory/descending BEP value and the current service cell in CS territory and the descending incoming level value of adjacent area; Wherein, the descending incoming level value of the current service cell in CS territory and adjacent area periodically reports by descending level measurement report, and the BEP value of up every channel in PS territory reports after the BTS place is measured, and the BEP value of descending every channel in PS territory incidentally arrives BS by Downlink ACK.
Step 402: the measurement report that is received is carried out interpolation and Filtering Processing;
With non-DTM mode class seemingly, interpolation adopts the worst-case value interpolation equally, Filtering Processing is also to adopt average RCV=∑
1 LfilterRCV
k/ L
FilterHandle, wherein L
FilterBe filter length, RCV
kBe BEP value and the descending incoming level value that reports in the measurement report.
Step 403: start switch decision;

Obtain in the PS territory a single channel BEP value promptly on the current channel in the PS territory in the measurement report after interpolation and Filtering Processing/descending BEP value.
A described single channel can be any single-channel one in PS territory, does not influence the realization of the embodiment of the invention.
Step 405: judge that the BEP value whether greater than the error threshold value, is then to change step 406 over to, otherwise changes step 408 over to;
When judging BEP value that step 404 obtains greater than the error threshold value, illustrate that then current quality of channel is lower, MS has the needs of switching cell, changes step 406 over to; Be not more than the error threshold value, then change step 408 over to.
Step 406: judge whether that continuous N time judgement BEP value greater than the error threshold value, is then to change step 407 over to, otherwise changes step 404 over to.
Equally, M time value can be adjusted immediately according to channel conditions, and when channel conditions was not good enough, this numerical value can be bigger than normal, and it is excessive influenced by channel conditions with the BEP value of avoiding obtaining; After continuous N time determines that the BEP value obtained is greater than the error threshold value, change step 407 over to; Judge that number of times does not arrive M time, then change step 404 over to, obtain the BEP value again and rejudge.
Step 407: judge whether to exist the adjacent area of CS territory incoming level value, be then to change step 411 over to, otherwise change step 412 over to greater than current service cell incoming level value.
Step 408: the descending incoming level value of obtaining CS territory current service cell and adjacent area.
The descending incoming level value of CS territory current service cell of obtaining and adjacent area is the descending incoming level value in the measurement report after step 402 interpolation and Filtering Processing that receives in the step 401.
Step 409: judge that the descending incoming level value in adjacent area, CS territory whether greater than the descending incoming level value of CS territory current service cell, switching hysteresis and level penalty value three sum, is then to change step 410 over to, otherwise changes step 412 over to.
The implication of level penalty value and switching hysteresis is with described in the step 309;
The difference of descending incoming level value in adjacent area, CS territory and level penalty value illustrates then that greater than the descending incoming level value of CS territory current service cell, switching hysteresis and level penalty value three sum the adjacent area possesses switching condition.
Step 410: whether the N continuous time descending incoming level value in judgement adjacent area, CS territory is then to change step 411 over to, otherwise changes step 408 over to greater than the descending incoming level value of CS territory current service cell, switching hysteresis and level penalty value three sum.
Equally, based on the accidental influence of avoiding channel fluctuation to bring, the judgement of step 409 also need be inferior repeatedly to improve the numerical value accuracy through N continuous, and N time implication can rule of thumb be provided with in advance flexibly with aforementioned M time.
Step 411: select an adjacent area to switch.
