Optionally, the user terminal alarm method provided by the foregoing embodiment is applied to the user terminal or applied to the management network device, and the two cases are respectively described in different embodiments.

Please refer to FIG. 3, which is a flowchart of a method for alerting a user terminal according to an exemplary embodiment of the present invention. The present embodiment is applied to the user terminal alarm system shown in FIG. 1A or FIG. 1B. The user terminal in the example is exemplified, and the method includes:

In step 301, the user terminal determines a security zone.

The security zone is a mobile zone set for the user terminal. The security zone is an area of the system preset or user-defined size. Generally, the security zone is an area that contains the current location of the user terminal. Optionally, the security zone is an area included in an administrative unit such as a cell, a building, a street, or a village where the user terminal is currently located. For example, the security zone is a supermarket, a stadium, and a train station where the user terminal is currently located.

The user terminal determines the security zone by the methods provided by the following different implementations:

In the first implementation manner, the user terminal acquires the current location information, and determines that the distance from the location information is less than or equal to the predetermined distance threshold.

Optionally, the working mode of the user terminal includes an anti-theft mode. When the user enters the area where the user terminal is prone to theft of the user terminal, such as a supermarket, a stadium, and a train station, the user terminal is enabled to adopt the anti-theft mode of the user terminal, and then the user terminal passes the The GPS or the interaction with the network side acquires its own location information and determines the security zone, wherein the predetermined distance threshold is a system preset value or a user-defined value. For example, if the predetermined distance threshold is 2000 meters, the security area is an area where the distance from the location information currently located by the user terminal is less than or equal to 2000 meters. In this implementation, the security zone determined by the user terminal is typically the zone identified by the latitude and longitude range of the security zone.

In a second implementation, the user terminal receives an area setting operation, and the area setting operation is used to set a security area.

Optionally, the area setting operation is used to select a map area in the map; then the user terminal invokes the map interface to determine a security area corresponding to the map area. In this optional implementation manner, the security area determined by the user terminal is the area identified by the latitude and longitude range corresponding to the map area.

Optionally, the area setting operation is used to set the area identifier corresponding to the security area, and the security area determined by the user is the area identified by the area identifier. Optionally, the area identifier is a name of the security area, and the name of the security area includes at least one of a name of the building included in the security area, a name of the administrative unit, and an enterprise name. For example, if the regional setting operation setting area identifier “xx stadium” received by the user terminal is used, the security area determined by the user terminal is the area formed by the xx stadium identified by the area identifier. It should be noted that, in this optional manner, the user terminal does not need to know the latitude and longitude range corresponding to the security area.

Optionally, the working mode of the user terminal includes an anti-theft mode, and the user is enabled to enter the user terminal when entering the supermarket, the stadium, the train station, and the like, which are prone to theft of the user terminal. In the anti-theft mode of the terminal, the user terminal displays or jumps to the regional setting interface, and the user performs the regional setting operation. The user terminal displays or jumps to the locale setting interface, and the user performs the regional setting operation as follows:

1. The user terminal displays or jumps to the map interface, and the user selects the map area in the map, and the user terminal invokes the map interface to determine the area indicated by the map area, that is, the security area.

2. The user terminal displays or jumps to the area identifier list, and the user selects the area identifier in the area identifier list, and the user terminal determines that the area identified by the area identifier is a security area. For example, the list of area identifiers displayed by the user terminal includes Jiangsu Province, Shanghai City, Zhejiang Province, and Hunan Province, and the user can select Shanghai, and the user terminal determines that the security area is Shanghai.

3. The user terminal displays or jumps to the input window, and the user inputs the area identifier in the input window, and the user terminal determines that the area identified by the area identifier is a security area. For example, if the user inputs Shanghai into the user terminal, the user terminal determines that the security zone is Shanghai.

In a third implementation manner, the user terminal acquires N pieces of position information during a historical movement, where N is an integer greater than 1, and the area formed by determining the N pieces of position information is a security area. In this optional implementation manner, the security area determined by the user terminal is the area identified by the latitude and longitude range corresponding to the map area.

Since the area where the user terminal carried by the user moves is usually fixed, for example, always moving in the xx city or the xx area, and for example, always moving on the route between the home and the company, the user terminal is optionally used. The moving area acts as a safe area. Optionally, the user terminal obtains the location information of the device at a predetermined time interval, and obtains a total of N location information. Generally, in order to improve the accuracy of the determined security zone, N is a large integer; The predetermined time interval is a system preset or a user-defined preset time interval, for example, obtaining its own position information every hour. In an exemplary example, as shown in FIG. 4, the user terminal acquires its own location information every hour. The schematic diagram of the acquired location information is as shown in FIG. 4, and the user terminal determines that the security area 410 is the location information. The area formed.

Step 302: The user terminal sends a security area to the management network device, so that the management network device determines the corresponding access network information list according to the security area.

Optionally, the security area that is sent by the user terminal to the management network device includes a latitude and longitude range corresponding to the security area and/or an area identifier of the security area.

When the management network device is a network element connected to the access network device, the user terminal sends a security zone to the access network device, and the access network device forwards the security zone to the management network device.

Optionally, when the user terminal sends a network attach request and/or a session request to the management network device by using the access network device, the security area is carried in the network attach request and/or the session request and sent to the management. Internet equipment. Alternatively, after the user terminal establishes a communication connection with the management network device by using the access network device, the security area is carried in the communication message and sent to the management network device.

Since the management network device is generally used to manage multiple user terminals, optionally, when the user terminal sends the security area to the management network device, the user terminal also sends the terminal identifier to the management network device. Optionally, the terminal identifier is used to identify the user terminal, and the terminal identifier includes an International Mobile Equipment Identity (IMEI), a Media Access Control (MAC) address, and an Internet Protocol (IP) of the user terminal. The address, and at least one of the International Mobile Subscriber Identification Number (IMSI). Optionally, the terminal identifier may be a temporary identifier that is allocated by the network device to the user terminal. For example, the terminal identifier is a globally unique Temporary UE Identity (GUTI).

When the management network device is an access network device connected to the user terminal, the user terminal directly sends a security area to the management network device. Optionally, after establishing a communication connection with the access network device, the user terminal carries the security area in the communication message and sends the information to the access network device.

Step 303: The management network device receives the security zone sent by the user terminal.

Correspondingly, the security area received by the management network device includes a latitude and longitude range corresponding to the security area and/or an area identifier of the security area.

Step 304: The management network device determines a corresponding access network information list according to the security area.

The access network information list includes an access network device list and/or a cell list whose cell coverage is located in the security area.

Optionally, when the security area received by the management network device includes a latitude and longitude range corresponding to the security area, the management network device determines the access network information list according to the latitude and longitude range.

Optionally, when the security area received by the management network device includes the area identifier of the security area, the management network device directly determines the access network information list according to the area identifier; or the management network device invokes the map interface to determine the latitude and longitude corresponding to the area identifier. Range, the access network information list is determined according to the latitude and longitude range. In the embodiment of the present invention, the management network device directly determines the access network information list according to the area identifier as an example.

In the foregoing two alternative manners, the management network device directly determines the access network information list according to the received security area, and specifically includes the following implementation manners:

In a possible implementation manner, the access network information list includes an access network device list. The method for the management network device to determine the access network device list includes the following steps, as shown in FIG. 5:

Step 501: Determine geographic location information of the access network device connected to the management network device.

In this embodiment, the management network device is a network element connected to the access network device, such as an MM network element or a third-party network element. Generally, the location information of each access network device is fixed and determined when the access network device is deployed, and the management network device connected to the access network device stores the geography of each access network device connected thereto. location information.

Step 502: Determine, according to the device identifier of the access network device that the geographical location information is located in the security area, determine the access network device list.

Optionally, the management network device stores a correspondence between the device identifier of the access network device and the geographic location information. Optionally, the geographic location information is a latitude and longitude of the access network device. The device identifier is used to identify the access network device. For example, in LTE, the device identifier is an eNodeB identifier (Identity, ID).

For example, a schematic diagram of the management network device receiving the security area 600 sent by the user terminal is shown in FIG. 6. The management network device stores the geographical location information of the access network device 611 to the access network device 615, and the access network device 611 is assumed. As shown in FIG. 6 , the location information of the access network device 615 and the security area 600 are as shown in FIG. 6 , and the access network device list determined by the management network device includes the device identifier of the access network device 613 and the access network device. The device identification of 614 and the device identification of access network device 615.

Since the coverage of an access network device is usually relatively large, when the user terminal moves outside the security area, the connection may still be an access network device located in the security area, and there is a certain error, so in order to reduce the error. In another possible implementation manner, the access network information list includes a cell list. The method for the management network device to determine the cell list includes the following steps, as shown in FIG. 7A:

Step 701: Determine a cell coverage range of each cell of the access network device connected to the management network device.

In this embodiment, the management network device is a network element connected to the access network device, such as an MM network element or a third-party network element; or the management network device is an access network device. The access network device saves the cell coverage of each cell covered by the access network device, and the management network device connected to the access network device stores the cell coverage of each cell covered by each access network device. Optionally, the access network device sends the coverage of each cell covered by the access network device to the management network device, and correspondingly, the management network device receives the coverage of each cell sent by the access network device, and saves each received Cell coverage.

Step 702: Determine a cell list according to a cell identifier of a cell whose cell coverage is located within the security zone.

Optionally, the management network device stores a correspondence between the cell identifier and the cell coverage, and the cell The identifier is used to identify the cell. Optionally, the cell identifier is a Physical Cell Identifier (PCI), and an Evolved UMTS Terrestrial Radio Access Network (E-UTRAN) cell global identifier (E- UTRAN Cell Global Identifier (ECGI) or other information used to identify a cell.

As a result, the coverage area of the cell is not completely coincident with the security area. Therefore, the management network device determines, according to the cell identifier of the cell that the area of the cell coverage that overlaps with the security area is greater than the predetermined threshold. List of cells. The predetermined ratio threshold is a system preset value or a user-defined value. For example, if the predetermined ratio threshold is 50%, when 80% of the cell coverage areas of a certain cell are located within the security area, it is determined that the area of the cell coverage of the cell that overlaps with the security area has a ratio of 80%. %, reaching a predetermined ratio threshold, and determining a cell list according to the cell identity of the cell.

For example, taking the access network device 612 and the access network device 614 in FIG. 6 as an example, the access network device 612 covers the cell A1, the cell A2, and the cell A3, and the access network device 614 covers the cell B1 and the cell B2. And cell B3, as shown in FIG. 7B, the coverage area of each cell is indicated by a broken line, and other access network devices are not shown. Assuming that the predetermined ratio threshold is 50%, it can be clearly seen from FIG. 7B that the proportion of the area in the cell A1, the cell A2, and the cell B2 that coincides with the security area 300 does not reach 50%, and the cell A3, the cell B1, and The area of the cell B3 that overlaps with the security zone 300 is 50%, and the cell list determined by the management network device includes the cell identity of the cell A3 covered by the access network device 612 and the cell covered by the access network device 614. The cell identity of B1 and the cell identity of cell B3 covered by access network device 614.

Step 305: The management network device sends the access network information list to the user terminal.

When the management network device is the access network device, the management network device directly sends the access network information list to the user terminal; when the management network device is the network element connected to the access network device, the management network device uses the access network device to The user terminal sends a list of access network information.

Step 306: The user terminal receives a list of access network information sent by the management network device.

After receiving the list of access network information sent by the management network device, the user terminal stores the access network information list. In actual implementation, after the user terminal sends a new security zone to the management network device, it receives a new access network information list sent by the management network device, and the user terminal stores the latest access network information list.

The coverage formed by the access network device and/or the cell included in the access network information list does not normally coincide with the security zone. For example, in the example shown in FIG. 6 above, the access network device column The table includes the device identifier of the access network device 613, the device identifier of the access network device 614, and the device identifier of the access network device 615, assuming each of the access network device 613, the access network device 614, and the access network device 615. The coverage is shown by the dashed line in Fig. 8A. Then, the coverage formed by the access network device 613, the access network device 614, and the access network device 615 (shown as a shaded portion in FIG. 8B) does not coincide with the security region 600 of the user terminal, and is optional. The user terminal updates the security area according to the received access network information list, and specifically includes the following steps, as shown in FIG. 8C:

Step 801: The user terminal acquires an access network coverage area corresponding to the access network information list.

Optionally, the step is implemented by the user terminal receiving the access network coverage area corresponding to the access network information list sent by the management network device. After determining the access network information list according to the security area, the management network device determines that the coverage of the cell coverage of the access network device included in the access network information list and/or the coverage of the cell coverage of the cell is the access network coverage. The area and the access network coverage area is sent to the user terminal.

It should be noted that, in some embodiments, the step may also be implemented by the user terminal according to the cell coverage of the access network device included in the received access network information list and/or the cell coverage of the cell. The coverage is the coverage area of the access network, which is not limited in this embodiment.

Step 802: The user terminal updates the security area according to the coverage area of the access network.

Optionally, the user terminal determines that the updated security area is an access network coverage area.

Step 307: The user terminal determines the currently connected access network information.

Optionally, the user terminal determines the device identifier of the currently connected access network device, or the user terminal determines the cell identifier of the currently connected cell.

The user terminal obtains the access network information of the access network device from the broadcast message of the access network device, including the device identifier of the access network device connected by the user terminal, or the cell identifier of the cell where the user terminal is located. In this step, the user terminal obtains the device identifier of the currently connected access network device, or the user terminal acquires the cell identifier of the currently located cell.

Step 308: The user terminal detects, according to the access network information list and the access network information currently connected by the user terminal, whether the user terminal is located outside the security area.

In a first implementation manner, when the access network information list includes the access network device list, the user terminal detects whether the access network device list includes the device identifier of the access network device currently connected by the user terminal; When the device list of the currently connected access network device is not included in the information list, it is determined that the user terminal is outside the security zone.

In a second implementation manner, when the access network information list includes a cell list, the user terminal detects Whether the cell identifier of the cell to which the user terminal is currently connected is included in the cell list; when the cell identifier of the currently connected cell is not included in the access network information list, it is determined that the user terminal is located outside the security zone.

It should be noted that the security area in this step is usually the updated security area. In some embodiments, the security area may also be a security area determined by the user terminal, which is not limited in this embodiment.

Step 309, when the user terminal is outside the security zone, an alarm signal is issued.

The alarm signal is used to alert the user terminal that the terminal is stolen. Optionally, the user terminal sends a voice alarm signal through the speaker component. Considering that in actual implementation, when the environment in which the user terminal is located is noisy, or the user terminal has been far away from the user, the user cannot hear the alarm signal of the user terminal, and when the user terminal detects that it is outside the security zone, the user terminal The management terminal sends an alarm message, and the alarm information is used to prompt the user terminal to be stolen. The management terminal is a terminal preset by the user for receiving alarm information of the user terminal, for example, a backup mobile phone of the user. Optionally, the user terminal sends an alarm message to the management terminal by using a short message, an email, and a push information, where the content and form of the alarm information are preset by the system or customized by the user. For example, when the user terminal detects that it is outside the security zone, it sends a text message to the management terminal, “Your mobile phone leaves the security zone, please pay attention to the security of the mobile phone and avoid theft.” Optionally, the alarm information sent by the user terminal to the management terminal further includes location information of the current location of the user terminal.

In actual implementation, after the user terminal is stolen, the thief usually performs a shutdown operation on the user terminal to prevent the user from searching, and when the user terminal detects that it is outside the security zone, the anti-theft operation is performed, and the ban is prohibited. The other terminal or access network device disconnects the communication connection for subsequent searching by the user. The theft prevention operation includes prohibiting the shutdown, prohibiting the disabling of the SIM card, disabling the flight mode, prohibiting the activation of the silent mode, and locking at least one of the user terminals.

In summary, the user terminal alarm method provided by the embodiment of the present invention detects whether the user terminal is located outside the security area according to the access network information list of the security area and the access network information currently connected by the user terminal, when the user terminal is detected. When the user is located outside the security zone, it indicates that the user terminal is stolen. At this time, the user terminal is actively sent an alarm signal to indicate the theft. The user terminal is not required to discover that the user terminal is stolen, and the user terminal can be found to be stolen and retrieved in a timely manner. terminal.

The user terminal alarming method provided by the embodiment of the present invention determines whether the user terminal has moved outside the security zone according to the currently connected access network information, and does not need to perform real-time positioning by using the GPS in the user terminal, thereby reducing the user terminal in the Prevent energy consumption during the process of theft.

The user terminal alarming method provided by the embodiment of the invention prevents the user terminal from performing operations such as shutting down and disabling the SIM card when detecting that the user terminal is outside the secure area, thereby preventing the thief from shutting down and disabling the SIM card after the user terminal is stolen. The method avoids the user's search and improves the probability of retrieving the user terminal.

In other optional embodiments based on the above embodiments, when the user terminal alarm method is applied to the management network device in the user terminal alarm system shown in FIG. 1, in the above step 304, the management network device is determined to be connected. After the network access information list, the correspondence between the storage terminal identifier and the access network information list, the access network information list corresponding to different user terminals is the same or different; for the same user terminal, the management network device is based on the received new one. After determining the new access network information list, the security area updates the correspondence between the terminal identifier and the access network information list.

Optionally, when the access network information acquired by the user terminal is the device identifier of the access network device currently connected by the user terminal, when the access network device connected to the user terminal changes, the new access network is sent to the management network device. Device ID of the device. For example, when the user terminal accesses the base station A, it sends the device identifier of the base station A to the MME. When the user terminal accesses the base station B in the process of moving, the device identifier of the base station B is sent to the MME, but when the user terminal is moving, When the base station A is always connected in the process, the device identifier of the base station A is not sent to the MME.

Optionally, when the access network information acquired by the user terminal is the cell identifier of the cell where the user terminal is currently located, when the cell where the user terminal is located changes, the cell identifier of the new cell is sent to the management network device. For example, when the user terminal is in the coverage of the cell 1 of the base station A, the cell identifier 1 of the cell 1 of the base station A is sent to the MME, and when the user terminal enters the coverage of the cell 2 of the base station A in the process of moving, The MME transmits the cell identity 2 of the cell 2 of the base station A. However, when the user terminal is always within the coverage of the cell 1 of the base station A during the mobile process, the cell identity 1 is not transmitted to the MME.

Step 905: The management network device receives the currently connected access network information sent by the user terminal.

Step 906: The management network device detects, according to the access network information list and the access network information currently connected by the user terminal, whether the user terminal is located outside the security area.

For the implementation of this step, refer to step 308 above, which is not described in this embodiment. It should be noted that the security zone in this step is also usually an updated security zone.

Step 907: When the user terminal is outside the security zone, the management network device controls the user terminal to send an alarm signal.

Specifically, the management network device sends a control command to the user terminal, where the control command is used to instruct the user terminal to send an alarm signal. Optionally, the control instruction is further used to indicate that the user terminal sends the alarm information to the management terminal, or is used to instruct the user terminal to perform the anti-theft operation.

It should be noted that, in the embodiment of the present invention, since the management network device needs to obtain the access network information from the user terminal, the user terminal needs to be in an ACTIVE state, and optionally, the user terminal is in the management network. After the device sends a secure zone, it is forbidden to enter the idle (ILDE) state.

In summary, the user terminal alarm method provided by the embodiment of the present invention detects whether the user terminal is located outside the security area according to the access network information list of the security area and the access network information currently connected by the user terminal, when the user terminal is detected. When the user is located outside the security zone, it indicates that the user terminal is stolen. At this time, the user terminal is actively sent an alarm signal to indicate the theft. The user terminal is not required to discover that the user terminal is stolen, and the user terminal can be found to be stolen and retrieved in a timely manner. terminal.

After receiving the security zone 1000 to the MME, the user terminal receives the cell list returned by the MME. The cell list includes the cell identity of the cell B1 covered by the base station 1010 shown in FIG. 10, the cell identity of the cell B2 covered by the base station 1010, and the base station. The cell identifier of the cell B3 covered by 1010 and the cell identifier of the cell A1 covered by the base station 1020. In this exemplary example, other base stations and cells in the security zone 1000 are not described.

When the user terminal is at the location 1031, the user terminal determines that the current cell is a base station. 1010 coverage cell B2, since the cell identity of the cell B2 is included in the cell list, the user terminal determines that it is currently in the stadium; when the user terminal moves to the location 1032, the user terminal determines that the current cell is the cell covered by the base station 1020. A1, the same reason is determined to be currently in the stadium; when the user terminal moves to the location 1033, the user terminal determines that the current cell is the cell A3 of the base station 1020, and since the cell identity of the cell A3 is not included in the cell list, the user terminal If it is determined that the user terminal is outside the stadium and the user terminal judges that it is stolen, an alarm signal is issued to prompt the user to be stolen.

In another optional embodiment, when the user terminal does not send the security area to the management network device, if the holder of the user terminal finds that the user terminal is stolen, the holder of the user terminal can also manage The terminal searches for the lost user terminal, and the method includes the following steps, as shown in FIG.

The management account is an account corresponding to the user terminal preset by the user, and the user terminal is saved in the server. The correspondence between the management account and the management account is usually saved.

Optionally, the user also sets a search range by using a management terminal, where the search range is a range set by the user after prescribing the location of the user terminal being stolen. For example, if the user finds that the user terminal is stolen in the movie theater, the search range is set to a movie theater. The range of areas included. The management terminal sends the terminal identifier of the user terminal to the management network device in the search range.

Step 1102: The management network device receives the terminal identifier sent by the management terminal.

Step 1103: The management network device detects whether the context information corresponding to the terminal identifier is included.
