Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, hereinafter with reference to the accompanying drawing in the embodiment of the present invention, technical scheme is described clearly and completely by embodiment, it is clear that, described embodiment is a part of embodiment of the present invention, rather than whole embodiments。Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention。
Embodiment one
With reference to shown in Fig. 1, the flow chart of the detection method of a kind of specified type community provided for the embodiment of the present invention one, the technical scheme of the present embodiment is applicable to the situation that specified type community is detected and searched。Wherein, it is intended that the community that type cell can configure for any specific, typical in the pseudo-base station community around current environment。Before testing, by all frequencies around current environment are scanned for, all there is signal cell with what obtain around current environment, all to have in signal cell to detect specified type community from this。The method can be performed by the detecting device of specified type community, and this device can adopt the mode of software and/or hardware to realize, and is arranged in communication terminal and performs。
The detection method of a kind of specified type community provided by the invention, the step of the method is as follows:
Configuration parameter in the cell system message that step 110, basis receive, obtains doubtful specified type community。
As mentioned above, cell system message specifically comprises the judgement information that can community normally resident, such as network identification parameter, cell selection parameters, system control parameters and network function parameter etc., configuration parameter in cell system message specifically refers to the parameter being arranged in each community in system message, it is possible to unique each community of mark。At this, only there is signal community, just this community can be detected thus receiving this cell system message, therefore, it is possible to detect that the community of cell signal strength value is for there being signal cell, detecting device is after having found out signal cell, obtain this cell system message having signal cell and configuration parameter therein, it is achieved the doubtful specified type community of surrounding is detected and searched。Therefore, in this step, the operation that detecting device preferentially performs is, surrounding is scanned for, to find out the frequency that all there is signal, secondly, according to Search Results, read the system message of one or more communities corresponding to each frequency and configuration parameter therein。
In this embodiment, it is preferred that, described specified type community is pseudo-base station community。
As mentioned above, known detecting device is by searching for frequency around, find out the signal cell that has in surrounding, and obtain system message and the configuration parameter of whole community, then determine the attribute of specified type community at this after, according to configuration parameter, the doubtful community of specified type community could be judged, in the present invention, described specified type community is specially pseudo-base station community, say, that, content according to configuration parameter, finds out doubtful pseudo-base station community from whole communities。
In sum, according to the configuration parameter in the cell system message received, it is possible to obtain doubtful specified type community by different embodiments, preferred embodiment one specifically include at this:
S1110, receiving all of system message having signal cell around current location, there to be the configuration parameter of signal cell described in obtaining, wherein, described configuration parameter at least includes public land mobile radio communication mark and Location Area Identification。
As mentioned above, after surrounding is scanned for by detecting device, having found out whole has signal cell, so all of system message having signal cell can be read out by detecting device, owing to this step purpose is in that to find out doubtful specified type community, it is thus desirable to obtain the parameter of community from system message, in subsequent step, judge whether this community is doubtful specified type community according to cell parameter。At this, acquisition configuration parameter the system message of signal cell is had from what read, configuration parameter at least includes public land mobile radio communication (PublicLandMobileNetwork, PLMN) mark and Location Area Identification (locationareacodeIdentity, LAC_ID), its reason is in that, for pseudo-base station community, pseudo-base station is by arranging the Location Area Identification of uniqueness, make user's mobile communication terminal device re-selecting cell and update lane place, thus user registers in pseudo-base station and is absorbed in pseudo-base station, therefore the Location Area Identification obtained in configuration parameter can be easy to search whether community is doubtful specified type community。
Public land mobile radio communication mark is used for identifying certain country, the cellular mobile communication networks of certain standard of certain operator, 3 PLMN are such as had in CONTINENTAL AREA OF CHINA, the CDMA-1X network of the GSM/GPRS/EDGE network of China Mobile, the GSM/GPRS network of CHINAUNICOM and China Telecom, therefore according to the PLMN mark obtained, it is known that communication network belonging to any one community。Location Area Identification is for identifying different lane place, in order to determine the position of mobile platform, the area of coverage of each PLMN is divided into many lane place, and when the paging amount under a lane place reaches an early warning thresholding, the number of cells that namely this lane place is corresponding reaches the upper limit, in order to not cause the situation that communication is slow, block up, being necessary for splitting, therefore a lane place can comprise one or more community。
In sum, according to PLMN and LAC, it may be determined that the lane place described in the operator described in any one community, communication network and this community that detecting device finds out。And the lane place according to this community detects whether as doubtful pseudo-base station community。
Whether the described Location Area Identification of the community that S1111, judgement have identical described public land mobile radio communication mark is unique, if so, then confirms that the unique community of described Location Area Identification is doubtful pseudo-base station community。
As mentioned above, it is known that specifying type cell in the present embodiment is pseudo-base station community, then judge that namely doubtful specified type community is judge doubtful pseudo-base station community。The public land mobile radio communication mark of known cell and Location Area Identification。For any one PLMN, its area of coverage is divided into many lane place, and a lane place can comprise one or more community。For pseudo-base station community, the reselecting parameters only passing through to arrange extreme optimization makes user's mobile communication terminal gravity treatment to pseudo-base station community, therewith by triggering user's position of mobile communication terminal district renewal identity information to obtain user's mobile communication terminal, can set up with user's mobile communication terminal and be connected, therefore after user's mobile communication terminal determines that pseudo-base station community is arrived in gravity treatment, pseudo-base station community is only by arranging a unique Location Area Identification in identifying at current public land mobile radio communication, user communication terminal could be guided to initiate registration, its identity information is sent in pseudo-base station community accurately, at this, the identity information of user communication terminal generally includes IMSI (InternationalMobileSubscriberIdentificationNumber, international mobile subscriber identity) and TMSI (TemporaryMobileSubscriberIdentity, interim identity)。If from community A gravity treatment to pseudo-base station community B (community A is identical with the Location Area Identification of community B), so gravity treatment is after the B of pseudo-base station community, owing to the community A before pseudo-base station community B and gravity treatment has identical Location Area Identification, pseudo-base station community cannot be ordered about user's mobile communication terminal launch position district and be updated, thus pseudo-base station community cannot obtain the identity information of communication terminal。It follows that pseudo-base station community is when identical public land mobile radio communication mark, Location Area Identification is unique。
Known, identical public land mobile radio communication mark is divided into multiple lane place, each lane place comprises one or more community, and pseudo-base station community Location Area Identification when identical public land mobile radio communication mark is unique, in whole communities that so detecting device searches, have in whole communities of identical public land mobile radio communication mark, the community with not unique positions district mark is pseudo-base station community scarcely, and have identical public land mobile radio communication mark whole communities in have unique positions district mark community may determine that as doubtful pseudo-base station community, namely doubtful specified type community, therefore in this step, by judging whether the described Location Area Identification with the community of identical described public land mobile radio communication mark uniquely determines whether this community is doubtful specified type community, if it is determined that when the described Location Area Identification with the community of identical described public land mobile radio communication mark is unique, can determine that this community is not doubtful specified type community, if it is determined that when the described Location Area Identification of community with identical described public land mobile radio communication mark is unique, can determine that this community is doubtful specified type community。
In sum, according to the lane place of the community of identical public land mobile radio communication mark uniquely or unique, can determine that whether this community is doubtful specified type community with this。
According to the configuration parameter in the cell system message received, it is possible to obtain doubtful specified type community by different embodiments, preferred embodiment two specifically include at this:
The all of cell signal strength value having signal cell and system message around S1120, reception current location, and the described cell signal strength value that arranges reception is identical, and obtain the configuration parameter in described system message, wherein, described configuration parameter includes reselecting parameters。
As mentioned above, after surrounding is scanned for by detecting device, having found out whole has signal cell, so detecting device detects all of cell signal strength value (RLA_C) having signal cell, at this, the different cell signal strength values having a signal cell are incomplete same, for the ease of different districts is carried out reselection evaluation, at this, the all of cell signal strength value having signal cell is set to identical parameter, the all of system message having signal cell with identical cell signal strength value is read out by detecting device subsequently, and have acquisition configuration parameter the system message of signal cell from what read, wherein, configuration parameter is reselecting parameters, reselecting parameters at least includes gravity treatment temporary offset value (TEMPORARY_OFFSET), the life cycle (PENALTY_TIME) of gravity treatment temporary offset value, the minimum access level (RXLEV_ACCESS_MIN) in community of the current community calculated, reselection offset value (CELL_RESELECT_OFFSET)。
Preferably, arrange all of described in have the cell signal strength value of signal cell be 30。
S1121, according to the described reselecting parameters described cell signal strength value identical with setting obtained, have the C2 value of signal cell described in calculating, wherein, C2 value corresponding to this identical described cell signal strength value is called benchmark C2 value。
In cell reselection process, its key factor is employing channel quality parameter C2 is standard, when the signal quality parameter C2 of adjacent area exceedes the channel quality parameter C2 of local area, cell reselection can be caused, make mobile terminal device from local area gravity treatment to adjacent area, namely C2 reselection criterion is utilized, it is possible to use family terminal gravity treatment is to the optimized appointment community of C2 value。Based on C2 reselection criterion, in all communities around current environment, pseudo-base station community is by configuring the reselecting parameters optimized very much, to obtain bigger C2 value, user terminal is made to be easier to gravity treatment to pseudo-base station community, it can be said that all around current environment have in signal cell, the channel quality parameter C2 of the community of pseudo-base station should be better than other normal cell。At this, the cell signal strength value being provided with signal cell is identical, then having the channel quality parameter C2 value of signal cell to can be described as benchmark C2 value, corresponding, the reselecting parameters of pseudo-base station community is better than other normal cell。It is the numerical value of network configuration in this reselecting parameters, the channel quality C2 of community can be calculated according to reselecting parameters。The computing formula of channel quality parameter C2 is as follows:
When PENALTY_TIME ≠ 11111,
C2=C1+CELL_RESELECT_OFFSET-TEMPORARY_OFFSET*H (PENALTY_TIME-T)；
As PENALTY_TIME=11111,
C2=C1-CELL_RESELECT_OFFSET；
Wherein, C1=RLA_C-RXLEV_ACCESS_MIN-Max ((MS_TXPWR_MAX_CCH-P), 0), MS_TXPWR_MAX_CCH is the maximum transmission power that network allows, P is the current community maximum transmission power calculated, generally MS_TXPWR_MAX_CCH≤P, therefore the computing formula of C1 is generally C1=RLA_C-RXLEV_ACCESS_MIN。
At this, known RLA_C is 30, and the reselecting parameters of pseudo-base station community is relatively more extreme and is better than normal cell, so can obtain all of benchmark C2 value having signal cell under identical cell signal strength value with this, when benchmark C2 value is more big, illustrate that the reselecting parameters of the community of this benchmark C2 value correspondence is also more extreme, such that it is able to judge that this community is doubtful pseudo-base station community。
S1122, from obtain all of described benchmark C2 value, extract the benchmark C2 value exceeding default reselection threshold。
As mentioned above; when setting all of signal strength values having a signal cell and being identical; the benchmark C2 value of the most pseudo-base station community of statistics; and the benchmark C2 value according to multiple pseudo-base station communities; staff empirically presets a reselection threshold, and the benchmark C2 value of pseudo-base station community would generally exceed this reselection threshold。For having signal cell for any one environment all, when pseudo-base station community makes that user terminal is easier to be chosen wherein, pseudo-base station community must configure a benchmark C2 value being better than other all neighbor cells, therefore this reselection threshold is as a standard, and the benchmark C2 value exceeding this reselection threshold may be the benchmark C2 value of pseudo-base station community。
It follows that the benchmark C2 value of all communities having signal that step S1121 obtains is extracted, extract whole benchmark C2 values exceeding default reselection threshold, then such benchmark C2 value is probably the benchmark C2 value of pseudo-base station community。
S1123, set described in exceed community corresponding to the benchmark C2 value of default reselection threshold as doubtful pseudo-base station community。
As mentioned above, all around known current environment have in signal cell, the reselecting parameters of pseudo-base station community is better than other normal cell, and the benchmark C2 value exceeding default reselection threshold is probably the benchmark C2 value of pseudo-base station community, therefore the community that whole benchmark C2 values exceeding default reselection threshold is corresponding is likely pseudo-base station community, it is likely to as normal cell, is doubtful pseudo-base station community at this by cell setting corresponding for whole benchmark C2 values exceeding default reselection threshold。
In sum, according in identical cell signal strength value situation, the reselecting parameters of pseudo-base station community is typically superior to the reason of the reselecting parameters of normal cell, so extract, from the whole benchmark C2 values obtained, the benchmark C2 value exceeding default reselection threshold, it may be determined that the community of such benchmark C2 value correspondence is doubtful pseudo-base station community。
According to the configuration parameter in the cell system message received, it is possible to obtain doubtful specified type community by different embodiments, preferred embodiment three specifically include at this:
The all of cell signal strength value having signal cell and system message around S1130, reception current location, and the described cell signal strength value that arranges reception is identical, and obtain the configuration parameter in described system message, wherein, described configuration parameter includes reselecting parameters。
Preferably, arrange all of described in have the cell signal strength value of signal cell be 30。
S1131, according to the described reselecting parameters described cell signal strength value identical with setting obtained, have the C2 value of signal cell described in calculating, wherein, C2 value corresponding to this identical described cell signal strength value is called benchmark C2 value,
S1132, all of described benchmark C2 value is ranked up according to order from small to large, and calculates the difference of adjacent two described benchmark C2 values successively。
As mentioned above, the reselecting parameters of known pseudo-base station cell configuration is typically superior to other normal cell of its environment, so when all of cell signal strength value having a signal cell is identical, the benchmark C2 value of pseudo-base station community is also superior to other normal cell of its environment。At this, all benchmark C2 values obtained are ranked up according to order from small to large, then the community being arranged in order can be respectively labeled as X1, X2, X3, X4 ..., under normal circumstances, in same environment, the reselecting parameters difference of normal cell is less, corresponding, in this same environment, the benchmark C2 of normal cell also differs less。For pseudo-base station community, in order to allow the user terminal can gravity treatment pseudo-base station community, pseudo-base station community generally configures and is better than the benchmark C2 that normal cell is a lot, and therefore for the pseudo-base station community of same environment and normal cell, the difference comparsion of both benchmark C2 is big。
It can thus be appreciated that, after order from small to large according to benchmark C2 is ranked up, calculate the difference of adjacent two benchmark C2 successively, and the difference calculated is labeled as CH1, CH2, CH3 ... successively, then the benchmark C2 difference ... of CH1 is the benchmark C2 difference of X2-community, community X1, CH2 to be the benchmark C2 difference of X3-community, community X2, CH3 be X4-community, community X3。
S1133, when the difference of adjacent two described benchmark C2 values exceedes default gravity treatment difference threshold, set the community corresponding more than or equal to all benchmark C2 values of wherein bigger described benchmark C2 value as doubtful pseudo-base station community。
As mentioned above, a gravity treatment difference threshold is preset at this, after all benchmark C2 values are arranged according to order from small to large, after the difference CHn-1 (Xn-Xn-1) of adjacent two benchmark C2 values is more than or equal to gravity treatment difference threshold, illustrate that these adjacent two benchmark C2 values are undergone mutation, then the community Xn that in community Xn and the Xn-1 that these adjacent two benchmark C2 values are corresponding, benchmark C2 value is bigger is likely pseudo-base station community。Owing to the benchmark C2 value of all communities (Xn+1, Xn+2, Xn+3 ...) after the Xn of community is all higher than this community Xn, so the benchmark C2 value based on pseudo-base station community is better than normal cell, then when the difference of adjacent two described benchmark C2 values exceedes default gravity treatment difference threshold, set the community corresponding more than or equal to all benchmark C2 values of wherein bigger benchmark C2 value as doubtful pseudo-base station community, say, that community Xn and all communities (Xn+1, Xn+2, Xn+3 ...) after are doubtful pseudo-base station community。
At this, the whole benchmark C2 values having signal cell obtained can also be arranged according to order from big to small, calculate the difference of adjacent two benchmark C2 values successively, so when the difference of adjacent two benchmark C2 values exceedes default gravity treatment difference threshold, set the community of all benchmark C2 values correspondence of the benchmark C2 value wherein bigger more than or equal to this as doubtful pseudo-base station community。
In sum, benchmark C2 value difference value based on pseudo-base station community and normal cell is bigger, and pseudo-base station community benchmark C2 value is typically superior to the reason of normal cell reselection parameter, the whole benchmark C2 values obtained are sorted according to order from big to small or from small to large, and calculate the difference of adjacent two benchmark C2 values successively, when the difference of adjacent two benchmark C2 values exceedes default gravity treatment difference threshold, it is determined that the community corresponding more than or equal to all benchmark C2 values of wherein bigger benchmark C2 value is doubtful pseudo-base station community。
This step 110 judges that the unique community of Location Area Identification is as doubtful specified type community under identical public land mobile radio communication identifies, or judge that the community exceeding the benchmark C2 value correspondence of default reselection threshold is as doubtful pseudo-base station community, or when the difference of two benchmark C2 values adjacent in tactic reselecting parameters exceedes default gravity treatment difference threshold, judge that the community corresponding more than or equal to all benchmark C2 values of wherein bigger benchmark C2 value is as doubtful pseudo-base station community, by one method of any of the above, the judgement of all communities around current environment that detecting device is searched out by realization, whole doubtful specified type communities can be obtained from all communities around current environment, such that it is able to only whole doubtful specified type communities is judged, to detect specified type community, this step has the advantage accurately judging doubtful specified type community, and correspondingly reduce the detection time of detecting device。
Step 120, resident described doubtful specified type community, and confirm whether described doubtful specified type community is specified type community according to the communication terminal communications status in described doubtful specified type community。
As mentioned above, doubtful specified type community is Location Area Identification uniquely whole communities in identical public land mobile radio communication mark that detecting device finds out, or exceed the community of the benchmark C2 value correspondence of default reselection threshold, or when the difference of two benchmark C2 values adjacent in tactic benchmark C2 value exceedes default gravity treatment difference threshold, the community corresponding more than or equal to all benchmark C2 values of wherein bigger benchmark C2 value, at this, if the doubtful specified type community that detecting device judges is as time multiple, a doubtful specified type cell list can be set up, the doubtful specified type community of each is detected and judge according to this list by detecting device successively。
In this step, confirm whether described doubtful specified type community is specified type community according to the communication terminal communications status in described doubtful specified type community, its reason is in that, pseudo-base station community is not set up actual connection with extraneous network, so when user communication terminal communicates in pseudo-base station community, its communications status there will be exception, and real base station must be set up with extraneous network and contact, therefore, when user communication terminal communicates in real base station, communication conditions is good and normal。Therefore, for each doubtful specified type community, according to the communication terminal communications status in this doubtful specified type community, detecting device can confirm whether this doubtful specified type community is specified type community。
When the doubtful specified type community of described acquisition is multiple, it is preferred embodiment each described doubtful specified type community resident successively at this, and confirms whether described doubtful specified type community is described specified type community according to the described communication terminal communications status in described doubtful specified type community。
As mentioned above, detecting device searches after around having signal cell, if it is determined that doubtful specified type community have multiple, then need successively each doubtful specified type community to be carried out the judgement of specified type community, therefore, resident doubtful specified type community successively, and confirm whether described doubtful specified type community is specified type community according to the communication terminal communications status in described doubtful specified type community。If detecting device detects that currently resident doubtful specified type community is specified type community, then this specified type community of detection device records, and this specified type community is reported user communication terminal, then detect whether next doubtful specified type community is specified type community more successively。Or after whole doubtful specified type cell detection is completed by detecting device successively, what record detected whole specifies type cell, this testing result is once reported user communication terminal, the testing result that user communication terminal reports according to detecting device, specified type community is shielded or follows the tracks of operation, it is to avoid user is absorbed in specified type community。
Preferably, known described configuration parameter also includes reselecting parameters, before each described doubtful specified type community resident successively, also include: obtain benchmark C2 value according to the reselecting parameters of all of described doubtful specified type community, according to benchmark C2 value to all of described doubtful resident order of specified type cell setting。
As mentioned above, when doubtful specified type community has multiple, reselecting parameters according to all of described doubtful specified type community and the corresponding benchmark C2 value obtained, based on C2 reselection criterion, doubtful specified type community big for benchmark C2 value is arranged in front, so benchmark C2 value is more big, and doubtful specified type community is more likely to be specified type community。Doubtful specified type cell list after arranging according to gravity treatment, each described doubtful specified type community resident, detects each doubtful specified type community, to find out wherein whole specified type communities successively。
Further, the described communication terminal communications status in described doubtful specified type community includes such as the next item down or its combination: whether receive note in Preset Time；Whether successful initiate calling；Whether successful send note；Whether mobile data cube computation is successful。
