Detailed Description
Features and exemplary embodiments of various aspects of the present invention will be described in detail below, and in order to make objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
The Third Generation Partnership Project (3 GPP) protocol defines that the terminal will measure signals of every neighboring cell. The terminal takes the neighboring cell satisfying the reselection condition as the target cell. When the terminal reselects the target cell, the terminal reads the broadcast message of the cell, wherein the broadcast message comprises the characteristic information of the location area identifier of the target cell, the frequency point of the cell, the physical cell identifier of the cell and the like, and other system messages. The location Area identifier may be a Tracking Area Code (TAC) or a Location Area Code (LAC).
Fig. 1 is a flowchart illustrating a cell camping method according to an embodiment of the present invention. In the embodiment of the present invention, the first server 200 stores a pseudo base station feature library corresponding to an operator and a location area. The number of location areas may be multiple, and the number of operators may also be multiple. For each location area, the location area corresponds to a pseudo base station feature information base for each operator. As an example, the location area may be a city.
It should be noted that, when the terminal 100 is handed over from another location area to a target cell located in the first location area, the terminal 100 sends its first location information and a target Public Land Mobile Network (PLMN) identifier of an operator to which the terminal 100 belongs.
After receiving the first location information of the terminal 100 and the target PLMN identification transmitted by the terminal 100, the first server 200 determines the first location area based on the first location information of the terminal 100.
As one example, the first location information of the terminal 100 may be latitude and longitude information in which the terminal 100 detects itself. The first server 200 may determine the city where the terminal 100 is located according to the longitude and latitude information reported by the terminal 100.
Then, the first server 200 determines a target operator to which the terminal 100 belongs based on the target PLMN identity. The first server 200 then transmits a pre-stored target pseudo base station characteristic information base corresponding to the target operator and the first location area to the terminal 100.
After the terminal 100 reselects to the target cell, the target characteristic information of the target cell is acquired. In some embodiments, the target feature information includes at least one of: the location area identification of the target cell, the frequency point of the target cell and the physical cell identification of the target cell.
Then, the terminal 100 determines whether the target pseudo base station feature information base acquired from the first server 200 has feature information matching the target feature information, and obtains a first determination result. If the first determination result is yes, the terminal 100 does not camp on the target cell, i.e., reselects to another cell.
It should be noted that the target pseudo base station characteristic information base is a pseudo base station characteristic information base corresponding to the first location area and the target operator and stored in advance by the first server 200.
In some embodiments, if the target characteristic information is a target location area identifier, the target pseudo base station characteristic information base is a target pseudo base station location area identifier base corresponding to the first location area and the target operator. And if the target pseudo base station position area identification base has the position area identification matched with the target position area identification, determining that the first judgment result is yes, otherwise, determining that the first judgment result is no.
In other embodiments, if the target characteristic information includes a target location area identifier and a frequency point of a target cell, the target pseudo base station characteristic information base includes a target pseudo base station location area identifier base corresponding to the first location area and the target operator, and a target pseudo base station frequency point base corresponding to the first location area and the target operator.
And if the target pseudo base station position area identification base has a position area identification matched with the target position area identification, and the target pseudo base station frequency point base has a frequency point matched with the frequency point of the target cell, determining that the first judgment result is yes, otherwise, determining that the first judgment result is no.
That is, if the target feature information of the target cell includes a plurality of feature information, the target pseudo base station feature information base includes a pseudo base station feature information base corresponding to each feature information. And when each piece of feature information in the target feature information has matched feature information in the corresponding pseudo base station feature information base, determining that the first judgment result is yes.
In order to solve the problem that the terminal 100 enters the pseudo base station, in the cell camping method provided in the embodiment of the present invention, when the terminal 100 reselects to a new target cell, target feature information about the cell in a broadcast message of the cell is read. If the target feature information belongs to the target pseudo base station feature information base, the terminal 100 does not reside in the target cell, and directly reselects to other cells, so that the user can be prevented from entering the pseudo base station.
In some embodiments of the present invention, the first server 200 stores not only a pseudo base station feature information base corresponding to an operator and a location area, but also a legal feature information base corresponding to an operator and a location area.
In the case that the first determination result is negative, the first server 200 may further send a target legal feature information base corresponding to the first location area and the target operator, which is stored in advance, to the terminal 100.
In the case that the first determination result is negative, the terminal 100 may further determine whether or not feature information matching the target feature information exists in the target legitimate feature information base corresponding to the first location area and the target operator, which is acquired from the first server 200.
If the first judgment result is negative and the target legal feature information base has feature information matched with the target feature information, determining that the target cell is a legal cell of the first position area, and residing the target cell.
If the first determination result is negative, and the target legal feature information base corresponding to the first location area and the target operator, which is obtained from the first server 200, does not have feature information matching the target feature information, the terminal 100 may first reside in the target cell and represent that the terminal may be in any one of the following three scenarios.
The first scenario is: the terminal 100 switches from the first location area to the other location area.
The second scenario is: the terminal 100 enters a new pseudo base station and the first server 200 does not store the characteristic information of the base station.
The third scenario is: the terminal 100 is the first terminal to enter a legitimate base station newly added by an operator.
Referring to fig. 2, in order to determine which of the above three scenarios the terminal 100 is now in, the terminal 100 transmits first information to the first server 200. Wherein the first information includes target feature information, a target PLMN identity, and second location information of the terminal 100. Wherein the second location information of the terminal 100 may be the current latitude and longitude information of the terminal 100.
The first server 200 receives the first information transmitted by the terminal 100. The first server 200 then determines a target operator based on the target PLMN identification and a second location area based on the second location information.
Since the first server 200 stores the second location area and the first legal feature information base corresponding to the target operator, the first server 200 may determine whether the terminal 100 is in the first scenario by determining whether the first legal feature information base has feature information matching the target feature information.
If the first server 200 determines that the first legal feature information base corresponding to the second location area and the target operator has feature information matching the target feature information, the first server 200 proves that the terminal 100 is switched from the first location area to the second location area, and then the first server 200 sends the first legal feature information base and the first pseudo base station feature information base corresponding to the second location area and the target operator to the terminal 100.
It should be noted that, the manner of acquiring the target pseudo base station characteristic information base and the target legal characteristic information base corresponding to the first location area and the target operator by the terminal 100 is the same as the manner of acquiring the first pseudo base station characteristic information base and the first legal characteristic information base, and is not described herein again.
The terminal 100 receives the first pseudo base station characteristic information base and the first legal characteristic information base associated with the second location area and the target operator, which are transmitted by the first server 200.
Then, the terminal 100 updates the first pseudo base station feature information base to the target pseudo base station feature information base, and updates the first legal feature information base to the target legal feature information base.
However, if the first server 200 determines that the first legitimate feature information library does not have feature information matching the target feature information, and determines whether the terminal 100 is in the second scenario or the third scenario, the first server 200 transmits the first information to the second server 300 to perform the second determination. It should be noted that the second server 300 is an operator server corresponding to the target operator.
It should be noted that, the operator server of each operator stores a legal feature information base and a pseudo base station feature information base corresponding to the operator in advance. The legal feature information base corresponding to the operator includes feature information of all legal cells under the operator. The pseudo base station feature information base corresponding to the operator comprises feature information bases of all pseudo base stations discovered by the operator.
After receiving the first information, the second server 300 determines whether feature information matching the target feature information exists in a legal feature information base corresponding to the target operator stored in the server. If the second server 300 determines that the legal feature information base corresponding to the target operator has feature information matching the target feature information, it determines that the target feature information is legal feature information.
In the case where the second server 300 determines that the target feature information is valid feature information, it sends first indication information to the first server 200. Wherein the first indication information is used to instruct the first server 200 to add the target feature information to a first legal feature information base corresponding to the second location area and the target operator.
The first server 200 adds the target feature information to the first legal feature information base based on the received first indication information.
That is, at this time, the terminal 100 is in the third scenario, that is, the terminal 100 enters a new legal cell of the target operator, but since the terminal 100 is the first terminal 100 entering the new legal cell, the feature information of the cell is not yet stored in the first legal feature information base stored in the first server 200. Therefore, in the case where it is determined that the first legitimate feature information base does not have feature information matching the target feature information, the first information is transmitted to the second server 300 in order to further discriminate whether the target cell is a legitimate cell or a counterfeit base station.
It should be noted that the first server 200 may also record the location area and the list of the terminals 100 corresponding to the operators. As an example, when the first server 200 issues each terminal with the legal feature information base and the pseudo base station feature information base corresponding to the B1 location area and the B2 operator, each terminal is associated with the two feature information bases, so that each terminal can be notified in time when the legal feature information base and the pseudo base station feature information base corresponding to the B1 location area and the B2 operator are updated.
Thus, the first server 200 will also send the target characteristic information and the second indication information to each terminal associated with the second location area and the target operator. And the second indication information is used for indicating the terminal to add the target characteristic information to the stored first legal characteristic information base.
Each terminal associated with the second location area and the target operator receives the target feature information and the second indication information sent by the first server 200 and adds the target feature information to the stored first legitimate feature information base based on the second indication information.
If the second server 300 determines that the legal feature information base corresponding to the target operator does not have feature information matched with the target feature information, it determines that the target feature information is pseudo base station feature information.
In the case where the second server 300 determines that the target characteristic information is the pseudo base station characteristic information, third indication information is sent to the first server 200. Wherein the third indication information is used to instruct the first server 200 to add the target feature information to the first pseudo base station feature information base corresponding to the second location area and the target operator.
The first server 200 adds the target characteristic information to the first pseudo base station characteristic information base based on the received third indication information.
That is, the terminal 100 is now in the second scenario, i.e., the terminal 100 is the first to enter a newly discovered cell of a pseudo base station. However, since the terminal 100 is the first terminal 100 to enter a new pseudo base station, the first pseudo base station feature information base stored in the first server 200 does not yet store the feature information of the cell.
Similarly, the first server 200 sends the target characteristic information and the fourth indication information to each terminal associated with the second location area and the target operator. Wherein the fourth indication information is used for instructing the terminal 100 to add the target characteristic information to the stored first pseudo base station characteristic information base. Then, the user can use the device to perform the operation,
each terminal associated with the second location area and the target operator receives the target feature information and the fourth indication information sent by the first server 200 and adds the target feature information to the stored first pseudo base station feature information base based on the fourth indication information.
It should be noted that, if the target cell is a pseudo base station, if the first determination result is negative, and if the target legal feature information base corresponding to the first location area and the target operator acquired from the first server 200 does not have feature information matching the target feature information, the terminal 100 resides in the target cell and cannot perform a service. Therefore, when the terminal 100 re-enters another normal cell from the target cell, the first information is sent to the first server 200.
When the target cell entered by the terminal 100 is a pseudo base station, the terminal 100 reads a broadcast message of the pseudo base station. The terminal 100 may find that the target feature information of the target cell does not belong to the target pseudo base station feature information base. If the terminal 100 finds that the location area identifier changes, it needs to send a location update request to the pseudo base station, and after receiving the request, the pseudo base station issues an identity identification request to the terminal 100. After receiving the identification request, the terminal 100 reports an identification response. If the pseudo base station entered by the terminal 100 is a GSM pseudo base station, the pseudo base station and the mobile phone have a short message interaction flow, and after acquiring the mobile phone information or sending the short message, the pseudo base station releases the connection with the mobile phone.
That is, if the target cell is a pseudo base station, the terminal 100 may roughly determine that the target cell is the pseudo base station through the signaling characteristic of the pseudo base station, and therefore, after the terminal 100 enters a normal cell from the target cell, the terminal sends the first information to the first server 200 to determine whether the target cell is the pseudo base station again, so as to improve the accuracy of determining the pseudo base station.
The first server 200 is arranged in the network and used for maintaining a legal feature information base corresponding to a location area and an operator and a pseudo base station feature information base corresponding to the location area and the operator. The first server 200 and the network of the operator are provided with interfaces, and a legal feature information base and a pseudo base station feature information base corresponding to the operator are obtained in real time through the interfaces, so that the target feature information of the pseudo base station reported by the terminal 100 is verified, and the timeliness of data updating and the accuracy of pseudo base station judgment are improved.
In the embodiment of the invention, when the database is designed, the legal feature information base and the pseudo base station feature information base are stored and updated according to the dimensionality of a city and an operator, so that the problems that the legal feature information base and the pseudo base station feature information base list maintained by a mobile phone are too large and the judgment time is long due to too large management areas, and the mobile phone and the network are frequently interacted due to frequent change of the database are avoided; or the management area is set to be too small, so that the mobile phone frequently changes the management area to cause frequent interaction. When the management area is set as the dimension of an urban operator, when a user enters an operator network in a new city, a legal feature information base and a pseudo base station feature information base corresponding to the operator to which the user terminal belongs in the current city can be obtained at the first time. When the pseudo base station is found, the first server 200 issues the pseudo base station update information to each terminal in the city, so that sharing among terminals is realized, and the terminal is prevented from entering the pseudo base station.

In the embodiment of the invention, when the terminal reselects to a new target cell, the target characteristic information about the cell in the broadcast message of the cell is read. If the target characteristic information belongs to the target pseudo base station characteristic information base, the terminal does not reside in the target cell and is directly reselected to other cells, so that the user can be prevented from entering the pseudo base station.
