Below in conjunction with accompanying drawing to a preferred embodiment of the present invention will be described in detail, should be appreciated that following illustrated preferred embodiment is only for instruction and explanation of the present invention, is not intended to limit the present invention.

Embodiments provide a kind of pseudo-base station test method, described method is applied in terminal; Newly-increased first parameter P in the program of the modulator-demodulator Modem of described terminal, described first parameter P is for estimating the possibility of described endpoint registration to the community under pseudo-base station coverage, and this value shows that more greatly described endpoint registration is larger to the possibility of the community under pseudo-base station coverage; When described terminal carries out community selection or gravity treatment, the first parameter described in described terminal initialization, preferably can initialization first parameter P=0; Certainly, the initial value of the first parameter can also be set to other integer, arranges flexibly according to practical situations.

The first pass schematic diagram of the pseudo-base station test method that Fig. 1 provides for the embodiment of the present invention; As shown in Figure 1, described method comprises:

Step 11: when carrying out community selection or gravity treatment, obtains the cell attribute of current candidate community.

Here, the cell attribute that terminal obtains comprises following seven property elements:

The signal strength signal intensity of described current candidate community, whether the minimum access in the community level Rxlev_Access_Min of described current candidate community, described current candidate community support GPRS (GPRS, GeneralPacketRadioService) function, the adjacent cell parameter of described current candidate community, the subdistrict frequency point allocation table carried in the cell system message 1 of described current candidate community, network side is to the identifying information required for the identification of terminal and whether receive the safety certification that network side initiates described terminal.Wherein, described adjacent cell parameter comprises: adjacent area BCCH distribution list; The BCCH distribution list of described adjacent area is issued by system message 2.

Step 12: according to described cell attribute, upgrades the first parameter, and described first parameter is for characterizing the possibility that described current candidate community own base station is doubtful pseudo-base station.

Here, in advance for each property element arranges corresponding condition, judge whether each property element meets corresponding condition one by one; When in seven property elements, be often judged as a property element meet for its arrange condition time, an operation is added to the first parameter P.Concrete:

When being judged as that described signal strength signal intensity exceedes default Second Threshold, add one to described first parameter P, described Second Threshold is the maximum of the signal strength signal intensity of legitimate base station, and preferably, this maximum can be taken as-50dBm;

When being judged as that described Rxlev_Access_Min exceedes the 3rd default threshold value, one is added to described first parameter P, described 3rd threshold value be greater than 0 positive integer, preferably, described 3rd threshold value is 3;

When being judged as that GPRS function is not supported in described current candidate community, one is added to described first parameter P;

When be judged as the adjacent cell parameter of the current service cell that the adjacent cell parameter of current candidate community is resident with described terminal have value be identical parameter and the ratio that value is identical parameter accounts for total number of parameters lower than the ratio value preset time, add one to described first parameter P, preferred described ratio value can value be 30%;

When being judged as that the subdistrict frequency point allocation table carried in the cell system message 1 of described current candidate community does not comprise described terminal at the frequency that described current service cell is resident, one is added to described first parameter P;

Before described terminal resides at described current candidate community, there is effective temporary user identifier (TMSI, TemporaryMobileSubscriberIdentity), at described endpoint registration behind described current candidate community, described terminal knows that network side is only international mobile subscriber identity IMSI and the mobile device international identity code IMEI of described terminal to the identifying information required for the identification of self, when but not needing TMSI, one is added to described first parameter P;

At described endpoint registration behind described current candidate community, when described terminal does not receive the safety certification of network side initiation, one is added to described first parameter P.

It should be noted that, before the aforesaid judgement whether meeting corresponding condition to the first five property element occurs in described endpoint registration to described current candidate community, the judgement that whether respective condition met to latter two property element occur in described terminal registered in described current candidate community by described current candidate community as terminal Serving cell after carry out in the process of routing update; The process of described routing update specifically refers to existing related description, repeats no more here.

Step 13: when the first parameter after upgrading exceedes default first threshold, determine that described current candidate community own base station is doubtful pseudo-base station.

Here, pre-set first threshold C (C is positive integer), in the embodiment of the present invention, 2≤C≤7, preferred C=5; When the first parameter P after terminal judges is upgrade does not exceed first threshold C, determine that described current candidate community is legitimate base station, continue to reside at current candidate community; When the first parameter P after terminal judges is upgrade exceedes first threshold C, determine that described current candidate community own base station is doubtful pseudo-base station, stop at the routing update of current candidate community, trigger described terminal and return and the next available cell residing at a Serving cell or reside in the candidate list of described terminal; Terminal by the characteristic parameter of the doubtful pseudo-base station determined, determine that this base station is time of doubtful pseudo-base station be added into the first concordance list.Wherein, described candidate list is issued by network side when terminal carries out community selection or gravity treatment.

The characteristic parameter of doubtful pseudo-base station

Be defined as the time of doubtful pseudo-base station

To the confirmation result of doubtful pseudo-base station

Table 1

The composition schematic diagram of the first concordance list that table 1 provides for the embodiment of the present invention; As shown in Table 1, the first concordance list includes three contents, respectively: the characteristic parameter of doubtful pseudo-base station, terminal are defined as time of doubtful pseudo-base station, network side to the confirmation result of doubtful pseudo-base station.

Wherein, the characteristic parameter of described doubtful pseudo-base station comprises: base station identity code (BSIC, BaseStationIdentityCode), definitely wireless channel numbers (ARFCN, AbsoluteRadioFrequencyChannelNumber), cell ID CellID, lane place coding (LAC, LocationAreaCode) etc.

Step 14: send for confirming that whether described doubtful pseudo-base station is the report message of pseudo-base station to network side.

Here, terminal transmission carries the report message of this doubtful pseudo-base station characteristic parameter to network side, determine whether this doubtful pseudo-base station is pseudo-base station by network side, end side receives the acknowledge message determined by network side, and it is the confirmation result of pseudo-base station or legitimate base station and described characteristic parameter that this acknowledge message carries this doubtful pseudo-base station.

Here, when sending report message to network side, terminal starts timer, when not receiving the acknowledge message of network side in timer was as 30 seconds, resends report message to network side; If resend report message pre-determined number continuously as after 3 times, when end side does not still receive the acknowledge message of network side, in the first concordance list, the network side that terminal upgrades doubtful pseudo-base station confirms that result be without responding.

Here, receive at terminal wait in the process of network validation message, this is wait state to the confirmation result of doubtful pseudo-base station for the Section 3 in table 1 and network side.When in timer, namely timer is not overtime, after terminal receives the acknowledge message of network side, stop the timing of timer, and according to the characteristic parameter of the pseudo-base station of carrying in network side acknowledge message, finding the record corresponding with described characteristic parameter in the first concordance list, is that the method for the confirmation result of pseudo-base station or legitimate base station upgrades the first concordance list by the wait state in record being updated to doubtful pseudo-base station.

Embodiments provide a kind of pseudo-base station test method, described method is applied to network side; Second schematic flow sheet of the pseudo-base station test method that Fig. 2 provides for the embodiment of the present invention; As shown in Figure 2, described method comprises:

Here, the report message for doubtful pseudo-base station of network side, specifically server receiving terminal transmission.

Step 22: according to the characteristic parameter of the doubtful pseudo-base station of carrying in report message, determine whether described doubtful pseudo-base station is pseudo-base station;

Here, in network configuration information, whether whois lookup exists the base station with this characteristic parameter, and when not finding, the base station determining to have this characteristic parameter is pseudo-base station; When finding, the base station determining to have this characteristic parameter is legitimate base station; Usually, the characteristic parameter of legitimate base station is provided with in network configuration information in advance.

In the present invention's preferred embodiment, when determining that doubtful pseudo-base station is pseudo-base station, described method also comprises:

Obtain the cell information at the terminal place sending described report message, described cell information comprises: encode LAC for cell ID CellID and lane place;

According to the cell information of the terminal of the described report message of transmission, determine the geographic range at the place, community of the terminal sending described report message, and using the geographic range of this geographic range as place, pseudo-base station, export this geographic range, in this geographic range, this pseudo-base station is investigated to facilitate network optimization personnel.

Usually, pseudo-base station and the close together reporting the community, terminal place (legal cells) of reporting message, by getting the geographical position of legal cells, tentatively determine the geographical position of pseudo-base station.Simultaneously, because legal CellID and LAC determines a unique legal cells jointly, when terminal resides at legal cells and sends report message in this legal cells to network side, the server of network side is previously stored with the corresponding relation of the geographic range that each legal cells information and this legal cells cover, in this corresponding relation, cell information according to legal cells is searched and the geographic range corresponding to this legal cells information, and using the geographic range of the geographic range of this output as place, pseudo-base station, server exports this geographic range to network optimization personnel, by network optimization, personnel investigate further.

Step 23: send the acknowledge message for described report message, carrying described doubtful pseudo-base station in described acknowledge message is pseudo-base station or the confirmation result for legitimate base station.

Here, described acknowledge message carries network side to this doubtful pseudo-base station is pseudo-base station or the confirmation result for legitimate base station.

When terminal receives the acknowledge message for described report message, stop the timing of timer, acknowledge message received by parsing, according to the characteristic parameter of the pseudo-base station of carrying in acknowledge message, find the record corresponding with described characteristic parameter in the first concordance list, the wait state in record is updated to the confirmation result that doubtful pseudo-base station is pseudo-base station or legitimate base station.

Usually, the quantity of the doubtful pseudo-base station of recording in the first concordance list of end side not only one, the successful interpolation of result is confirmed to specifying doubtful pseudo-base station for convenience of end side, when to send this doubtful pseudo-base station be the confirmation result of pseudo-base station or legitimate base station to network side, also the characteristic parameter of this doubtful pseudo-base station is back to end side, to facilitate end side according to this characteristic parameter, corresponding renewal confirms result.

In addition, as shown in Table 1, described first concordance list records terminal and determines that base station is the time of doubtful pseudo-base station, its reason is: in the embodiment of the present invention, by a certain characteristic parameter in described first concordance list, the base station determining to have described characteristic parameter is time of doubtful pseudo-base station and described base station is that the confirmation result of pseudo-base station or legitimate base station is as a record, certain preservation duration is had as 24 hours to the described recording configuration in the first concordance list, after length terminates when saved, when described terminal gets same doubtful pseudo-base station (same characteristic parameter) again, again report message is sent to network side, to be reaffirmed by network side whether the base station with this characteristic parameter is pseudo-base station, the problem that this scheme dynamically updates for solving network side base station information.

As previously mentioned, the confirmation result that terminal is added in the first concordance list comprises: network side without response, doubtful pseudo-base station is pseudo-base station, doubtful pseudo-base station is three kinds of results such as legitimate base station; In the present embodiment, by network side without responding the situation being considered as doubtful pseudo-base station and belonging to pseudo-base station.

When described terminal initiates community selection or cell reselection again, obtain the characteristic parameter of candidate cell own base station, search in the first concordance list whether there is described characteristic parameter; When find and base station belonging to the community with this characteristic parameter of recording in described first concordance list be pseudo-base station or network side without response time, forbid accessing described pseudo-base station; When finding and the base station confirming belonging to the community that the confirmation of recording in described first concordance list has this characteristic parameter is legitimate base station, allow to reside at this legitimate base station.

From such scheme, in embodiments of the present invention, by determining whether the base station belonging to terminal current candidate community is pseudo-base station alternately between end side and network side; Further, first determine doubtful pseudo-base station by end side, confirm whether described doubtful pseudo-base station is pseudo-base station by network side again, only be confirmed whether that the method into pseudo-base station is different by network side from of the prior art, mutual by between terminal and network side of this programme, while adding network side process, contemplates the access characteristic of each terminal as mobile phone self, increase feasibility, improve implementation and be detected as power.
