Description

Method for performing deactivation and activation operation in location service

The present invention relates to the positioning technology of network equipment, and particularly to a method for performing deactivation and activation operations in a location service. BACKGROUND OF THE INVENTION

The location service (LCS, Location Service) of a mobile communication network is to obtain location information of a user equipment (UE) through positioning technology. UE refers to a target UE terminal located in a mobile communication network. The location information may be geographic latitude and longitude information or local streets. Location information. The location information obtained by the LCS system can be provided to the target UE for its own positioning; it can also be provided to other client applications, such as institutions and individuals, that request the location information of the target UE for value-added services. Therefore, location services have a wide range of functions in emergency rescue, vehicle navigation and intelligent transportation systems, work scheduling and team management, mobile yellow page query, and enhanced network performance. In the 3rd Generation Partnership Project (3GPP), the LCS specification and the functional mode, structure, state description, and message flow of the entire LCS system are described.

Currently, in the LCS specification of 3GPP, the location information request initiated by the requester to the target UE is divided into two types: immediate location information request and delayed location information request.

Immediate location information request means that the LCS system immediately locates the target UE after receiving the location information request from the requesting end to the target UE, and then immediately sends the positioning result to the requesting end, that is, the LCS system receives the location information sent by the requesting end. After the request, the current location information of the target UE is provided to the requesting end immediately.

Delayed location information request refers to the requesting end requesting the LCS system to provide the location information of the target UE to it at a future point in time or when a certain event occurs, that is, the LCS system needs to receive the position information request from the requesting end to the target UE. After a delay, wait N2004 / 000229 does not provide the requesting end with the current location information of the target UE until the delay event is triggered.

In addition, 3GPP allows the requester to request the LCS system to provide it with the location information of the target UE periodically, that is, the requester defines the start time point and the end time point and a certain periodic logic, and requires the LCS system to follow the periodic logic to the It provides location information of the target UE. The above-mentioned location information request may be referred to as a periodic location information request. From a certain point of view, the periodic location information request is one of the delayed location information requests, so the periodic location information request can be classified into the delayed location information request type.

Figure 1 is a schematic diagram of the logical structure of the LCS network. As shown in Figure 1, the requester 101 requests the location information of the target UE 103 from the LCS system 102, the LCS system 102 performs legality authentication on the requester 101, and checks whether the target UE 103 allows the The requesting end 101 obtains its location information. If the requesting end 101 authenticates the validity of the LCS system 102, the LCS system 102 locates the target UE 103, and then provides the requesting end 101 with the position information of the target UE 103; otherwise, the LCS system 102 The requester 101 rejects the location information request from the target UE 103.

Since the location information belongs to the private information of the target 1; £, the location information of the target UE should be strictly protected. Since the location service belongs to a service subscribed by the target UE, at some times, for the purpose of protecting its privacy information, the target UE needs to request the LCS system to turn off the location service to it, that is, to deactivate the location service of the target UE; When the target UE roams out of the home service area, the positioning cost may increase due to roaming. Due to the consideration of charges, the target UE may also need to request the LCS system to close the location service to it. Correspondingly, the target UE may also need to request the LCS system to restore the location service, that is, activate the location service of the target UE. At present, the 3GPP LCS specification does not define a deactivation operation and a corresponding implementation process of the activation operation, so that the target UE cannot control the opening and closing of the subscribed location service. Summary of the invention

In view of this, an object of the present invention is to provide a method for performing deactivation and activation operations in a location service, which is convenient for a target user equipment to perform opening control and shutdown control of a contracted location service.

In order to achieve the above object, the present invention provides a method for performing deactivation and activation operations in a location service. The method includes the following steps:

A. The target user equipment sends a location service operation request to the location service system, where the operation request carries the target user equipment identifier;

B. After receiving the location service operation request, the location service system performs a corresponding operation according to the target user equipment identifier and the content of the operation request in the location service operation request.

C. The location service system processes the subsequent location information requests according to the content of the location service operation request described in step A.

The location service operation request is a location service deactivation operation request,

The step A is: the target user equipment sends a location service deactivation operation request to the location service system, and the location service deactivation operation request carries a target user equipment identifier; the step B is: the location service system receives the location service After activating the operation request, the location service of the target user equipment is set to be invalid;

The step C is: After the location service system sets the location service of the target user equipment to be invalid, the location service system refuses to process a subsequent location information request initiated by the requesting end to the target user equipment.

The step B further includes:

Bl l, after receiving the location service deactivation operation request, the location service system searches for a currently activated location information request for the target user equipment, and if it is found, execute step B12, otherwise, perform step B13;

B12. The location service system terminates the search for the current location initiated on the target user equipment. The position letter in the activated state, the processing of the request;

B13. The location service system sets the location service of the target user equipment as invalid.

After step B12, the method further includes: the location service system sends a positioning failure response message to the requesting end of the location information request processing.

The positioning failure response message carries parameters, and the parameters indicate that the target user equipment terminates the processing of the location information request initiated by the requester by the location service system.

The location service operation request is a location service activation operation request,

The step A is: the target user equipment sends a location service activation operation request to the location service system, and the location service activation operation request carries a target user equipment identifier;

The step B is: after the location service system receives the location service activation operation request, setting the location service of the target user equipment as valid;

The step C is: After the location service system sets that the location service of the target user equipment is valid, the location service system no longer refuses to process a subsequent request for a location information request initiated by the target user equipment.

After step B, the following steps are further included:

B21. The location service system determines whether the location service operation on the target user equipment is successful. If successful, perform step B22, otherwise, perform step B23;

B22. The location service system returns the location service operation success response message to the target user device.

B23 The location service system returns a location service operation failure response message to the target user equipment, and ends the current operation of the location service.

The location service operation failure response message in step B23 carries the corresponding failure reason value.

Performing the corresponding operation according to the target user equipment identifier and operation request content in the location service operation request described in step B, further including: the location service system receives the location service operation After making the request, the location service authenticates the target user equipment that sends the location service operation request. If the target user equipment passes the authentication, the location service system performs the corresponding operation according to the target user equipment identifier and the operation request content in the location service operation request. Otherwise, the location service operation request of the target user equipment is rejected.

The location service system described in step B sets the location service of the target user equipment to invalid. The location service status flag of the target user equipment is set to a deactivated state flag.

The location service system described in step B sets the location service of the target user equipment to be valid. The location service status flag of the target user equipment is set to an active state flag.

Mode of Carrying Out the Invention

The present invention is described in detail below with reference to the drawings.

FIG. 2 is a flowchart of a deactivation operation performed by the target UE and the LCS system according to the present invention. As shown in FIG. 2, a process of the deactivation operation performed by the target UE and the LCS system includes the following steps:

Steps 201 to 202: The target UE sends a location service deactivation operation request to the LCS system, and the location service deactivation operation request carries the target UE identity. LCS system received After the location service deactivation operation request, the active location information request currently initiated for the target UE is searched according to the target UE identity, and if found, step 203 is performed; otherwise, step 205 is performed.

Step 203: The LCS system disables the searched active location information request, and the LCS system terminates the processing of the failed location information request.

Step 204: The LCS system sends a positioning failure response message to the corresponding requester that failed its location information request. The positioning failure response message may carry a parameter, which indicates that the target UE terminates the location information request initiated by the LCS system to the requesting end. Processing. This step may be omitted, that is, the LCS system may not return any message to the corresponding requesting end.

Step 205: The LCS system sets the location service of the target UE to be invalid, that is, the location service of the target UE is deactivated. The LCS system determines whether the location service of the target UE is successfully set to be invalid. If yes, go to step 206; 207.

Step 206: The LCS system returns a location service deactivation operation success response message to the target UE, notifying the target UE that the location service deactivation operation it initiated has been successfully performed, and ending the current location service deactivation operation.

Step 207: The LCS system returns a location service deactivation operation failure response message to the target UE, where the location service deactivation operation failure response message carries a corresponding failure reason value, and notifies the target UE that the location service deactivation operation initiated by it fails to execute.

Step 206 or step 207 may be omitted, that is, the LCS system may not return any response message to the target UE. If step 206 or step 207 is omitted, the step of the LCS system in step 205 to determine whether the location service of the target UE is successfully set to be invalid may also be used. Omitted.

FIG. 3 is a flowchart of the activation operation of the target UE with the LCS system according to the present invention. As shown in FIG. 3, the process of the activation operation of the target UE with the LCS system includes the following steps: Step 301: The target UE sends a location service to the LCS system. An activation operation request, where the location service activation operation request carries the target UE identity. Step 302: After receiving the location service activation operation request, the LCS system sets the location service of the target UE as valid according to the target UE identifier, that is, activates the location service of the target UE. The LCS system determines whether the location service of the target UE is successfully set to be valid. If yes, go to step 303; otherwise, go to step 304.

Step 303: The LCS system returns a location service activation operation success response message to the target UE, notifies the target UE that the location service activation operation it initiated has been successfully performed, and ends the current location service activation operation.

Step 304: The LCS system returns a location service activation operation failure response message to the target UE. The location service activation operation failure response message carries a corresponding failure reason value, and notifies the target UE that the location service activation operation it initiated failed to execute.

Step 303 or step 304 may be omitted, that is, the LCS system may not return any response message to the target UE; if step 303 or step 304 is omitted, the step of the LCS system in step 302 to determine whether the location service of the target UE is successfully set to be valid may also be Omitted.

In the LCS system of the mobile communication network, a location service status flag of the target UE may be set, and the location service status flag is used to identify whether the location service of the target UE is in an activated state or a deactivated state. The LCS system can allow the target UE to use the short message service (SMS) as a message bearer to perform information interaction with the LCS system, that is, the target UE can send a location service deactivation operation request or a location service activation operation request to the LCS system through the SMS. . When the target UE needs to close the location service, the edited short message with specific meaning can be sent to the specified address. For example, the user edits the short message LCS + off and sends it to 9999, indicating that the LCS system is requested to deactivate the location service of the target UE. operating. At this time, the LCS system can authenticate the target UE to determine whether the target UE has the authority to request the LCS system to perform the location service deactivation operation. For example, the LCS system requires the target UE to provide the location service deactivation operation password. The deactivation operation password is consistent with the location service deactivation operation password corresponding to the target UE stored in the LCS system. After the UE authenticates, the LCS system accepts the location service deactivation operation request initiated by the target UE; otherwise, the LCS system rejects the location service deactivation operation request initiated by the target UE.

After the target UE passes the authentication, the LCS system searches for the active position information request currently initiated by the target UE. If it finds the active position information request currently initiated by the target UE, forcing these position information requests to be invalid, and then A positioning failure response message is sent to the corresponding requesting end, and the positioning failure response message carries a parameter indicating that the target UE terminates the location information request it initiated; then the LCS system invalidates the location service of the target UE, that is, the target UE ’s The location service status flag is set to the deactivated status flag. If no active location information request is initiated for the target UE, the LCS system directly disables the location service of the target UE. Once the location service of the target UE is invalidated, the LCS system will reject the location information request to the target UE in the subsequent process.

When the target UE needs to restart the location service, the edited short message with specific meaning can be sent to the specified address. For example, the target UE edits the short message LCS + on and sends it to 9999, indicating that the LCS system is requested to perform the location service of the target UE. Activate operation. At this time, the LCS system can authenticate the target UE and determine whether the target UE has the authority to request the LCS system to perform the location service activation operation. For example, the LCS system requires the target UE to provide a location service activation operation password. The password is consistent with the location service activation operation password corresponding to the target UE stored in the LCS system, and then the target UE passes authentication, and the LCS system accepts the location service activation operation request initiated by the target UE; otherwise, the LCS system rejects the location service initiated by the target UE. Activate operation request.

After the target UE passes the wife right, the LCS system validates the location service of the target UE, that is, sets the location service status flag of the target UE to the active state flag. Once the location service of the target UE is enabled, the LCS system no longer rejects the location information request to the target UE in the subsequent process, and processes the location information request normally. The LCS system may also allow the target UE to send a location service deactivation operation request or a location service activation operation request to the LCS system in a voice bearer manner. When the target UE user needs to close the location service, he can enter the location service management process by dialing a certain phone number. For example, if the user dials 13800138001, the LCS system will play a voice prompt to the user. For example, "To activate the location service, press 1. Location. Please press 2 "for service activation operation. The user is prompted to enter the required operation. After the user enters" Γ "according to the prompt, the LCS system can further authenticate the target IJE to determine whether the target UE has the authority to request the LCS system to perform the location service to be activated. For example, the LCS system plays a prompt voice to the target UE user, "Please enter the password for the location service deactivation operation", and requires the target UE user to provide the location service deactivation operation password. If the location service provided by the target UE user deactivates the operation password and LCS, The system stores the same password as the location service deactivation operation of the target UE user. Then the target UE user passes authentication and the LCS system accepts the location service deactivation operation request initiated by the target UE; otherwise, the LCS system rejects the Location service deactivation operation request.

After the target UE user passes the authentication, the LCS system searches for the location information request that is currently initiated on the target UE and is active. If a location information request that is currently initiated on the target UE and is in the active state is found, forcing these location information requests is invalid. Then, a positioning failure response message is sent to the Xiangzhuang requester, and the positioning failure response message carries a parameter, which indicates that the target UE terminates the location information request it initiated; then the LCS system disables the location service of the target TJE, That is, the location service status flag of the target UE is set to the dead state flag. If no active location information request is currently initiated for the target UE, the LCS system directly disables the location service of the target UE. Once the location service of the target XJE is invalidated, the LCS system will reject the location information request to the target UE in the subsequent process.

When the target UE user needs to restart the location service, he can also enter the location service management process by dialing the phone number 13800138001, and the LCS system plays a prompt to the user Voice, for example, "1 for location service deactivation operation, and 2 for location service activation operation", the user is prompted to enter the required operation. After the user enters "2" as prompted, the LCS system can further authenticate the target UE. Identify whether the target UE has permission to request the LCS system to perform location service activation operations. For example, the LCS system plays a prompt voice to the target UE user, "Please enter the password for the location service activation operation", and requires the target UE user to provide the location service activation operation password. The location service activation operation password provided by the user is consistent with the location service activation operation password corresponding to the target UE stored in the LCS system, and then the target UE passes authentication, and the LCS system accepts the location service activation operation request initiated by the target UE; otherwise, the LCS system The location service activation operation request initiated by the target UE is rejected.

After the target UE passes authentication, the LCS system validates the location service of the target UE, that is, sets the location service status flag of the target UE to the active state flag. Once the location service of the target UE is enabled, the LCS system no longer rejects the location information request to the target UE in the subsequent process, and processes the location information request normally.

In short, the above descriptions are merely preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention.
