The authorization request message of the information determines the location trigger corresponding to the location information included in the received authorization request message according to the correspondence between the location information and the location trigger, and sends the determined location trigger to the gateway. The device, wherein the location trigger is used to instruct the gateway device to report the location information of the terminal device according to the location information reporting rule configured for the location trigger, so that, according to the location information of the terminal device reported by the gateway device, Configuring a location trigger for the location information of the subscribing terminal device for the gateway device, because the reporting rules of the location information set in the location trigger are different, the number of times the gateway device reports the location information of the terminal device can be effectively reduced, thereby further reducing Transmission of invalid signaling in the network system , increased the performance of the system equipment.

The various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Embodiment 1:

FIG. 1 is a schematic flowchart diagram of a method for subscribing terminal device location information according to Embodiment 1 of the present invention. The method can be as follows.

Step 101: The policy and charging rule function PCRF receives an authorization request message sent by the gateway device.

The authorization request message includes location information that the terminal device currently accesses the gateway device.

In step 101, when the terminal device sends an IP-CAN (IP-Connectivity Access Network) setup request message to the gateway device, the gateway device determines location information of the terminal device accessing the gateway device.

The manner in which the terminal device sends an IP-CAN setup request message to the gateway device may be The IP-CAN Establish Request message is sent or sent through other messages, which is not limited here.

The gateway device sends an authorization request message to the PCRF (Policy and Charging Rules Function) device through the Gx interface, and carries the location information of the current access gateway device of the terminal device in the authorization request message.

The manner in which the gateway device sends the authorization request message to the PCRF may be sent through a CCR-Initial (Credit Control Request-Initial) message, or may be sent through other messages, which is not limited herein.

It should be noted that the gateway device includes, but is not limited to, a GGSN (Gateway GPRS Support Node) device, a PGW (Packet Gateway) device, and a UGW (Unified Gateway) device.

It should be noted that the location information of the terminal device includes, but is not limited to, CGI (Cell Global Identification), RAI (Routing Area Identity), and SAI (Serving Area Identity). TAI (Tracking Area Identity), ECGI (Extended Cell Global Identification).

Step 102: The PCRF determines, according to the correspondence between the location information and the location trigger, a location trigger corresponding to the location information included in the received authorization request message.

The location trigger is used to instruct the gateway device to report the location information of the terminal device according to the location information reporting rule configured for the location trigger.

In step 102, since the PCRF divides the serving cell in the coverage area, the first type area that needs to track the location information of the terminal device in real time and the second type area that does not need to track the location information of the terminal device in real time are divided, so that The terminal device in the first type of area is capable of implementing a pre-configured internet access policy.

It should be noted that, in the first type of area and the second type of area, the first type of area can be regarded as a control area of the PCRF configuration, that is, a pre-configured Internet access policy, and a second The type area can be regarded as a non-managed area of the PCRF configuration, where One" and "second" have no substantial meaning, but are used to distinguish the types of regions in which the PCRF is divided.

The difference between the control area and the unmanaged area of the PCRF is that the PCRF divides the cells in the coverage area into the control area and the non-control area according to the management policy, and stores the identification information of the control area and/or the unmanaged area locally. The information is identified, and the terminal device accessing the control area limits the execution of the terminal device part of the service when the service request is initiated.

The PCRF limits the services in the control area, or restricts the execution of the services of the terminal equipment. It can be determined according to actual needs. It can also be determined according to the location information of the control area. It can also be determined according to the authority of the terminal to register or apply for services. Make a limit.

Since the PCRF is to divide the serving cell in the coverage area, the first type of area obtained by the division includes at least one serving cell, and the corresponding typed second type area includes at least one serving cell.

In addition, the serving cell included in the first type of area may be composed of multiple adjacent serving cells, or may be composed of multiple serving cells that are not adjacent, that is, the identification information of the first type of area and the included serving cell are established. Corresponding relationship between the identification information; the serving cell included in the second type of area may be composed of multiple adjacent serving cells, or may be composed of multiple serving cells that are not adjacent, that is, the second type of area is established. Correspondence between the identification information and the identification information of the included serving cell.

As shown in Table 1, a schematic table of the correspondence between the identification information of the established first type area and the identification information of the included serving cell is as follows:

第一类型区域的标识信息Identification information of the first type of area	包含的服务小区的标识信息Identification information of the included serving cell
		RAI1RAI1	CGI1、CGI2、CGI3、……CGI1, CGI2, CGI3, ...
RAI3RAI3	CGI7、CGI8、CGI9、……CGI7, CGI8, CGI9, ...	RAI1RAI1	CGI1、CGI2、CGI3、……CGI1, CGI2, CGI3, ...
RAI3RAI3	CGI7、CGI8、CGI9、……CGI7, CGI8, CGI9, ...	……......	……......

Table 1

As can be seen from Table 1, the area belonging to the first type of area includes: an area in which the identification information is RAI1 and an area in which the identification information is RAI3, wherein the RAI1 area includes serving cells such as CGI1, CGI2, and CGI3, and RAI3 The service area including CGI7, CGI8 and CGI9 is included in the area.

As shown in Table 2, a schematic table of the correspondence between the identification information of the established second type area and the identification information of the included serving cell is as follows:

第二类型区域的标识信息Identification information of the second type of area	包含的服务小区的标识信息Identification information of the included serving cell
		RAI4RAI4	CGI4、CGI5、CGI6、……CGI4, CGI5, CGI6, ...
RAI5RAI5	CGI10、CGI11、CGI12、……CGI10, CGI11, CGI12, ...	RAI4RAI4	CGI4、CGI5、CGI6、……CGI4, CGI5, CGI6, ...
RAI5RAI5	CGI10、CGI11、CGI12、……CGI10, CGI11, CGI12, ...	……......	……......

Table 2

As can be seen from Table 2, the area belonging to the second type of area includes: an area in which the identification information is RAI4 and an area in which the identification information is RAI5, wherein the RAI4 area includes service areas such as CGI4, CGI5, and CGI6, and the RAI5 The service area including CGI10, CGI11 and CGI12 is included in the area.

After the UEF divides the serving cell in the coverage area, the location trigger corresponding to the first type area and the location trigger corresponding to the second type area are determined, that is, the location trigger corresponding to the control area is determined. The position trigger corresponding to the control area.

In a first aspect, a correspondence between location information included in the first type of region and a small-granularity location trigger is established.

The small-granularity location trigger is used to indicate that the gateway device reports the terminal device when it is determined that the location information of the terminal device is changed from one serving cell to another serving cell in the first type of area. Location information.

In a second aspect, a correspondence between location information included in the second type of area and a large-granularity location trigger is established.

The large-grained location trigger is configured to instruct the gateway device to report location information of the terminal device when determining that the location information of the terminal device is changed from one area to another area.

It should be noted that the small-granularity location trigger is used to indicate that the gateway device reports the location information when the location information of the terminal device is changed from one serving cell to another serving cell in the first type area. The location information of the terminal device, for example, the gateway device reports the location information of the terminal device when it is determined that the location information of the terminal device is changed from CGI1 to CGI2. Or the gateway device reports the location information of the terminal device when it is determined that the location information of the terminal device is changed from CGI1 to CGI7.

The large-granularity location trigger is used to indicate that the gateway device reports location information of the terminal device when determining that the location information of the terminal device is changed from one area to another area, for example, the gateway device determines the When the location information of the terminal device is changed from the RAI 4 to the RAI 5, the location information of the terminal device is reported, or the gateway device reports the location information of the terminal device to be changed from the RAI 5 to the RAI 3, and reports the terminal device location information.

It should be noted that the established correspondence may be to establish a corresponding relationship between the first aspect and a corresponding relationship of the second aspect, or to establish a correspondence relationship of the first aspect or establish a correspondence relationship of the second aspect, and only establish the corresponding relationship. After the correspondence of one aspect, there is an implied correspondence on the other hand.

For example, the correspondence between the location information contained in the first type of area and the small-granularity location trigger is established. If the location information A does not belong to the first type of area, it is considered to belong to the second type of area, and the reported location information is A. When the location information A does not belong to the first type area, that is, does not correspond to the small-granularity location trigger, it is considered that the location information A corresponds to the large-granularity location trigger.

It should be noted that the correspondence between the location information included in the established first type region and the small granularity location trigger and the correspondence between the location information contained in the established second type region and the large granularity location trigger may be stored. Locally, the PCRF can also be stored on other devices. If it is stored in other devices (for example, SPR (Subscriber ProfiIe Repository)), the PCRF obtains the established correspondence from other devices during use.

The small granularity trigger may be, but is not limited to, a USER_LOCATION_CHANGE trigger, which may be, but is not limited to, a USER_LOCATION_RAI_CHANGE trigger.

After receiving the authorization request message sent by the gateway device, the PCRF determines the location trigger corresponding to the location information included in the received authorization request message according to the correspondence between the location information and the location trigger.

Specifically, the PCRF determines the current access terminal of the terminal device included in the authorization request message. The location information of the gateway device is location information included in the first type area or location information included in the second type area.

And determining, by the PCRF, the location included in the received authorization request message when determining that the location information that the terminal device currently accesses the gateway device included in the authorization request message belongs to the location information included in the first type area. The location trigger corresponding to the information is a small-granularity location trigger.

The determining, by the PCRF, the location information included in the received authorization request message when determining that the location information that the terminal device currently accesses the gateway device in the authorization request message belongs to the location information included in the second type of area The location trigger corresponding to the information is a large granularity position trigger.

Step 103: The PCRF sends the determined location trigger to the gateway device.

In step 103, when the PCRF sends the determined small-granularity location trigger to the gateway device, the gateway device configures the small-granularity location trigger after receiving the small-granularity location trigger sent by the PCRF. The location information reporting rule is used as a rule for subscribing to the terminal device location information, and the location information reporting rule configured by the small-granularity location trigger is installed, and the change of the location information of the terminal device is started.

In another embodiment of the present invention, the PCRF sends a CCA-Initial response message to the gateway device, where the CCA-Initial response message carries the determined small-granularity location trigger.

In addition, the CCF-Initial response message sent by the PCRF further carries policy information for assisting the terminal device to access the Internet, wherein the policy information for assisting the terminal device to access the Internet includes QoS parameter information, charging information, and service execution rule list information. .

The business execution rule list information includes business information that restricts execution.

During the execution of the mobile service of the terminal device, the gateway device monitors whether the location information change of the terminal device matches the location information reporting rule configured by the small-granularity location trigger, and determines the location information change and the small-granularity location trigger of the terminal device. When the configured location information reporting rules match, the location information of the terminal device is sent to the PCRF.

For example, during the execution of the mobile service of the terminal device, the location information of the gateway device monitoring terminal device is switched from the serving cell CGI1 of the RAI1 to the serving cell CGI3 of the RAI1, belonging to one service cell in the first type area being changed to another service. The cell is matched with the location information reporting rule configured by the small-granularity location trigger. At this time, the gateway device needs to report the location information RAI1-CGI3 of the terminal device to the PCRF.

When the PCRF sends the determined large-granularity location trigger to the gateway device, the gateway device reports the location information of the large-granularity location trigger configuration after receiving the large-granularity location trigger sent by the PCRF. As a rule for subscribing to the location information of the terminal device, the location information reporting rule configured by the large-granular location trigger is installed, and the change of the location information of the terminal device is started to be monitored.

During the execution of the mobile service of the terminal device, the gateway device monitors whether the location information change of the terminal device matches the location information reporting rule configured by the large-granularity location trigger, and determines the location information change of the terminal device and the large-granularity location trigger. When the configured location information reporting rules match, the location information of the terminal device is sent to the PCRF.

For example, during the execution of the mobile service of the terminal device, the location information of the gateway device monitoring terminal device is switched from the serving cell CGI1 of the RAI1 to the serving cell CGI5 of the RAI4, belonging to changing from one area to another, and the large-granularity location trigger The configured location information reporting rules are matched. In this case, the gateway device needs to report the location information of the terminal device (for example, CGI5, or RAI4-CGI5, in any specific form) to the PCRF.

In another embodiment of the present invention, the PCRF sends the determined location trigger to the Gateway devices, including:

It should be noted that the case where the PCRF first allocates location trigger information to the gateway device is not applicable.

When determining, by the PCRF, the location trigger corresponding to the location information included in the received authorization request message, the determined location trigger has the same situation as the location trigger used by the gateway device configuration, and therefore, the determination needs to be determined. Whether the location trigger and the location trigger used by the gateway device configuration belong to the same location trigger.

The determined location trigger belongs to the same location trigger as the location trigger used by the gateway device configuration, and the determined location trigger will not be sent to the gateway device, or the gateway device is notified by sending a response message. The location trigger does not need to be updated.

Embodiment 2:

FIG. 2 is a schematic flowchart diagram of a method for subscribing terminal device location information according to Embodiment 2 of the present invention. Embodiment 2 of the present invention is an invention under the same inventive concept as Embodiment 1 of the present invention. It can be as follows.

Step 201: The gateway device sends an authorization request message to the policy and charging rule function PCRF.

In step 201, when the terminal device sends an IP-CAN (IP-Connectivity Access Network) setup request message to the gateway device, the gateway device determines the location information of the terminal device accessing the gateway device.

The manner in which the terminal device sends the IP-CAN setup request message to the gateway device may be sent through an IP-CAN Establish Request message, or may be sent through other messages, which is not limited herein.

It should be noted that the location information of the terminal device includes, but is not limited to, CGI (Cell Global Identification), RAI (Routing Area Identity), and SAI (Serving Area Identity). TAI, ECGI.

Step 202: Receive a location trigger sent by the PCRF.

The location trigger is a location trigger determined by the PCRF corresponding to the location information included in the received authorization request message according to the correspondence between the location information and the location trigger.

In step 202, the location trigger received by the gateway device to be sent by the PCRF is determined by using the method described in step 102 in the first embodiment of the present invention, and is not described in detail herein.

Step 203: Report the location information of the terminal device according to the location information reporting rule configured by the location trigger.

In step 203, the position trigger includes a small granularity position trigger and a large granularity position trigger.

The large-grained location trigger is configured to instruct the gateway device to report location information of the terminal device when determining that the location information of the terminal device is changed from one region to another region.

Case 1: The received location trigger is a small-granularity location trigger.

After receiving the small-granularity location trigger sent by the PCRF, the gateway device sends the small-granularity bit The location information reporting rule configured by the trigger is used as a rule for subscribing to the location information of the terminal device, and the location information reporting rule configured by the small-granular location trigger is installed, and the change of the location information of the terminal device is started.

Specifically, the gateway device, when receiving the location information reported by the terminal device, determines that the location information of the terminal device is changed from one serving cell in the first type area to another serving cell, reporting the Location information of the terminal device.

Specifically, when receiving the location information reported by the terminal device, the gateway device determines that the identifier information of the region corresponding to the received location information is adjacent to the region corresponding to the location information previously received by the neighboring device. Whether the identification information is the same.

For example, during the execution of the mobile service of the terminal device, the location information of the gateway device monitoring terminal device is switched from the serving cell CGI1 of the RAI1 to the serving cell CGI3 of the RAI1, belonging to one service cell in the first type area being changed to another service. The cell matches the location information reporting rule configured by the small-granularity location trigger. At this time, the gateway device needs to locate the location information of the terminal device. RAI1-CGI3 is reported to the PCRF.

In another embodiment of the present invention, when it is determined that the identifier information of the area corresponding to the received location information is different from the identifier information of the area corresponding to the location information received by the previous time, according to the The location information reporting rule of the small-granularity location trigger configuration, reporting the location information of the terminal device and the identification information of the area corresponding to the location information, and sending an authorization change message.

The identifier information of the area is used to notify the area change of the location information of the PCRF terminal device.

For example, during the execution of the mobile service of the terminal device, the location information of the gateway device monitoring terminal device is switched from the serving cell CGI1 of the RAI1 to the serving cell CGI8 of the RAI3, and the identification information of the area in the location information of the terminal device is changed. According to the small-scale location information trigger currently configured by the gateway device, the location information RAI3-CGI8 of the terminal device needs to be reported to the PCRF, and an authorization change message is sent.

Specifically, when receiving the authorization change message sent by the gateway device, the PCRF determines, according to the correspondence between the location information and the location trigger, a location trigger corresponding to the location information currently sent by the gateway device, and determines the determined location trigger. Whether the location trigger configured by the gateway device belongs to the same location trigger, and the determined location trigger is not in the same location trigger as the location trigger used by the gateway device configuration, and the determined location trigger is sent to the location trigger The gateway device.

For example, in the above example, it is assumed that the location information of the terminal device is switched from the serving cell CGI1 of the RAI1 to the serving cell CGI5 of the RAI4, since the location trigger corresponding to the RAI1 is a small granularity location trigger and the location trigger corresponding to the RAI4 is a large granularity location. a trigger, where the determined location trigger and the location trigger used by the gateway device configuration do not belong to the same location trigger, will be determined to be large A granularity location trigger is sent to the gateway device.

The location information of the terminal device is switched from the serving cell CGI1 of the RAI1 to the serving cell CGI8 of the RAI3, since the location trigger corresponding to the RAI1 is a small-granularity location trigger and the location trigger corresponding to the RAI3 is a small-granularity location trigger, at the determined location The trigger and the location trigger used by the gateway device configuration belong to the same location trigger, and the determined small-granularity location trigger may be sent to the gateway device, or the determined small-granularity location trigger may not be sent to the location The gateway device sends an authorization response message to inform the gateway device that the location trigger is not changed.

Case 2: The received location trigger is a large granularity position trigger.

After receiving the large-granularity location trigger sent by the PCRF, the gateway device uses the location information reporting rule of the large-granularity location trigger configuration as a rule for subscribing the terminal device location information, and installs the location of the large-granularity location trigger configuration. The information reports the rules and starts monitoring the change of the location information of the terminal device.

Specifically, the gateway device, when receiving the location information reported by the terminal device, determines that the location information of the terminal device changes from one area to another area, and reports the location information of the terminal device.

Specifically, the gateway device determines, when receiving the location information reported by the terminal device, Whether the identification information of the area corresponding to the received location information is the same as the identification information of the area corresponding to the location information received by the previous time.

For example, during the execution of the mobile service of the terminal device, the location information of the gateway device monitoring terminal device is switched from the serving cell CGI1 of the RAI1 to the serving cell CGI5 of the RAI4, belonging to changing from one area to another, and the large-granularity location trigger The configured location information reporting rules are matched. In this case, the gateway device needs to report the location information of the terminal device, RAI4-CGI5, to the PCRF.

For example, in the above example, it is assumed that the location information of the terminal device is switched from the serving cell CGI5 of the RAI 4 to the serving cell CGI2 of the RAI1, since the location trigger corresponding to the RAI 4 is a large granularity location trigger and the location trigger corresponding to the RAI 1 is a small granularity location. The trigger, the determined location trigger and the location trigger used by the gateway device configuration do not belong to the same location trigger, and the determined small-granularity location trigger is sent to the gateway device.

The location information of the terminal device is switched by the serving cell CGI5 of the RAI 4 to the serving cell CGI 10 of the RAI 5, since the location trigger corresponding to the RAI 4 is a large granularity location trigger and the location trigger corresponding to the RAI 5 is a large granularity location trigger, at the determined location The trigger and the location trigger used by the gateway device configuration belong to the same location trigger, and the determined large-granularity location trigger may be sent to the gateway device, or the determined small-granularity location trigger may not be sent to the location The gateway device sends an authorization response message to inform the gateway device that the location trigger is not changed.

In another embodiment of the present invention, when it is determined that the identifier information of the area corresponding to the received location information is the same as the identifier information of the area corresponding to the location information previously received by the previous time, according to the large The location information reporting rule configured by the granularity location trigger does not report the location information of the terminal device.

For example, during the execution of the mobile service of the terminal device, the location information of the gateway device monitoring terminal device is switched from the serving cell CGI6 of the RAI4 to the serving cell CGI5 of the RAI4, belonging to one service cell in the second type area being changed to another service. The cell does not match the location information reporting rule configured by the large-granularity location trigger (or determines the identifier of the area corresponding to the received location information and the identifier of the area corresponding to the previously received location information. The information is the same. At this time, the gateway device does not need to report the location information RAI4-CGI5 of the terminal device to the PCRF.

With the solution of the second embodiment of the present invention, the gateway device sends an authorization request message to the policy and charging rule function PCRF, where the authorization request message includes location information of the terminal device currently accessing the gateway device, and receives the PCRF. a location trigger that is sent, wherein the location trigger is a location trigger corresponding to the location information included in the received authorization request message determined by the PCRF according to the correspondence between the location information and the location trigger And reporting the location information of the terminal device according to the location information reporting rule configured by the location trigger, so that the reporting device of the location information set in the location trigger is different, thereby effectively reducing the reporting device of the gateway device The number of location information further reduces the transmission of invalid signaling in the network system, increasing the performance of the system equipment.

Wherein, in the 2G communication system, the identifier of the serving cell A is CGI1, the identifier of the serving cell B is CGI2, the identifier of the serving cell C is CGI3, and the identifier of the serving cell D is CGI4;

In the 3G communication system, the identifier of the serving cell A is SAI1, the identifier of the serving cell B is SAI2, the identifier of the serving cell C is SAI3, and the identifier of the serving cell D is SAI4;

In the LTE communication system, the identifier of the serving cell A is TAI1, the identifier of the serving cell B is TAI2, the identifier of the serving cell C is TAI3, and the identifier of the serving cell D is TAI4.

Step 301: The terminal device sends an IP-CAN setup request message to the gateway device.

It should be noted that in the 2G system or the 3G system, the gateway device may be a GGSN; in the LTE system, the gateway device may be a PGW.

When the terminal device sends an IP-CAN setup request message to the gateway device, determining location information of the terminal device accessing the gateway device.

Step 302: The gateway device sends an authorization request message to the PCRF.

The authorization request message carries the location information of the terminal device currently accessing the gateway device.

It is assumed that the location information of the terminal device currently accessing the gateway device is the serving cell A of the area 1.

In step 302, the gateway device Gx interface sends an authorization request message to the PCRF device, and the authorization request message carries the location information of the terminal device currently accessing the gateway device, and the location information of the terminal device currently accessing the gateway device is the gateway device according to the gateway device. It is determined by receiving the IP-CAN setup request message.

It should be noted that the manner in which the gateway device sends an authorization request message to the PCRF is sent by using a CCR-Initial message.

Step 303: The PCRF determines, according to the correspondence between the location information and the location trigger, a location trigger corresponding to the location information included in the received authorization request message.

The position trigger includes a small granularity position trigger and a large granularity position trigger.

The implementation of the step 303 is the same as the embodiment of the step 102 in the first embodiment of the present invention, and will not be described in detail herein.

Step 304: The PCRF sends the determined location trigger to the gateway device.

Step 305: When receiving the location trigger sent by the PCRF, the gateway device uses the location information reporting rule configured by the location trigger as a rule for subscribing the terminal device location information, and installs the location information reporting rule configured by the location trigger, and The monitoring of the change of the location information of the terminal device is started.

In another embodiment of the present invention, the PCRF sends a CCA-Initial response message to the gateway device, where the CCA-Initial response message carries the determined location trigger.

In addition, the CCF-initial response message sent by the PCRF further carries policy information for assisting the terminal device to access the Internet, wherein the policy information for assisting the terminal device to access the Internet includes QoS parameter information, Billing information and business execution rule list information.

In step 305, when receiving the small-granularity location trigger delivered by the PCRF, the gateway device uses the location information reporting rule configured by the small-granularity location trigger as a rule for subscribing to the terminal device location information, and installing the small-granularity location. The location information of the trigger configuration reports the rule, and starts monitoring the change of the location information of the terminal device.

When receiving the large-granularity location trigger sent by the PCRF, the gateway device uses the location information reporting rule of the large-granularity location trigger configuration as a rule for subscribing the terminal device location information, and installs the location of the large-granularity location trigger configuration. The information reports the rules and starts monitoring the change of the location information of the terminal device.

Step 306: When determining that the location information of the terminal device changes, the gateway device reports the location information of the terminal device according to the location information reporting rule configured by the location trigger.

In step 306, during the execution of the mobile service of the terminal device, the gateway device monitors whether the location information change of the terminal device matches the location information reporting rule configured by the location trigger, and determines the location information change and the location trigger of the terminal device. When the location information reporting rules of the device match, the location information of the terminal device is sent to the PCRF.

Specifically, when the location trigger received by the gateway device is a small-granularity location trigger, the gateway device determines the identifier of the region corresponding to the received location information when receiving the location information reported by the terminal device. Whether the information is the same as the identification information of the area corresponding to the position information received by the previous time.

For example, during the execution of the mobile service of the terminal device, the location information of the gateway device monitoring terminal device is switched from the serving cell CGI1 of the RAI1 to the serving cell CGI2 of the RAI1, belonging to one service cell in the first type area being changed to another service. Cell, configured with small granularity location triggers The location information reporting rules are matched. At this time, the gateway device needs to report the location information RAI1-CGI2 of the terminal device to the PCRF.

For example, during the execution of the mobile service of the terminal device, the location information of the gateway device monitoring terminal device is switched from the serving cell CGI1 of the RAI1 to the serving cell CGI3 of the RAI2, and the identification information of the area in the location information of the terminal device is changed. According to the small-scale location information trigger currently configured by the gateway device, the location information RAI2-CGI3 of the terminal device needs to be reported to the PCRF.

Specifically, when the location trigger received by the gateway device is a large-granularity location trigger, the gateway device determines the identifier of the region corresponding to the received location information when receiving the location information reported by the terminal device. Whether the information is the same as the identification information of the area corresponding to the position information received by the previous time.

And determining, according to the location information configured by the large-granularity location trigger, when the identifier information of the area corresponding to the received location information is different from the identifier information of the area corresponding to the location information received by the previous time. The rule is to report the location information of the terminal device and the identifier information of the area corresponding to the location information, where the identifier information of the area is used to notify the area change of the location information of the PCRF terminal device.

For example, during the execution of the mobile service of the terminal device, the location information of the gateway device monitoring terminal device is switched from the serving cell CGI1 of the RAI1 to the serving cell CGI3 of the RAI2, belonging to changing from one area to another, and the large-granularity location trigger The configured location information reporting rules are matched. In this case, the gateway device needs to report the location information of the terminal device, RAI2-CGI3, to the PCRF.

Determining the identification information of the area corresponding to the received location information and the previous reception of the neighboring When the identification information of the area corresponding to the location information is the same, the location information of the terminal device is not reported according to the location information reporting rule configured by the large-granularity location trigger.

For example, during the execution of the mobile service of the terminal device, the location information of the gateway device monitoring terminal device is switched from the serving cell CGI3 of the RAI2 to the serving cell CGI4 of the RAI2, belonging to one service cell in the second type area being changed to another service. The cell does not match the location information reporting rule configured by the large-granularity location trigger (or determines the identifier of the area corresponding to the received location information and the identifier of the area corresponding to the previously received location information. The information is the same. At this time, the gateway device does not need to report the location information RAI2-CGI4 of the terminal device to the PCRF.

Step 307: The gateway device determines, according to the location information reported by the terminal device, the identifier information of the area corresponding to the received location information and the area corresponding to the previous received location information. When the identification information is different, an authorization change message is sent to the PCRF.

The authorization change message includes location information of the terminal device and identifier information of an area corresponding to the location information.

Step 308: Receive an authorization change response message sent by the PCRF.

The authorization change response message is sent by the PCRF when determining that the location information trigger corresponding to the location information reported by the terminal device and the location trigger configured by the gateway device do not belong to the same location trigger. The authorization change response message includes a location information trigger corresponding to the location information reported by the terminal device.

Specifically, in step 308, when receiving the authorization change message sent by the gateway device, the PCRF determines, according to the correspondence between the location information and the location trigger, a location trigger corresponding to the location information currently sent by the gateway device, and determines Whether the determined location trigger and the location trigger configured by the gateway device belong to the same location trigger, and the determined location trigger does not belong to the same location trigger as the location trigger used by the gateway device configuration, and the determined location A trigger is sent to the gateway device.

For example, in the above example, it is assumed that the location information of the terminal device is switched from the serving cell CGI1 of the RAI1 to the serving cell CGI3 of the RAI2, since the location trigger corresponding to the RAI1 is a small granularity location touch. The location trigger corresponding to the initiator and the RAI2 is a large-granularity location trigger. The determined location trigger and the location trigger used by the gateway device configuration do not belong to the same location trigger, and the determined large-granularity location trigger is sent. To the gateway device.

The location information of the terminal device is switched from the serving cell CGI1 of the RAI1 to the serving cell CGIE of the RAI3, since the location trigger corresponding to the RAI1 is a small-granularity location trigger and the location trigger corresponding to the RAI3 is a small-granularity location trigger, at the determined location The trigger and the location trigger used by the gateway device configuration belong to the same location trigger, and the determined small-granularity location trigger may be sent to the gateway device, or the determined small-granularity location trigger may not be sent to the location The gateway device sends an authorization response message to inform the gateway device that the location trigger is not changed.

The location information of the terminal device is switched by the serving cell CGI3 of the RAI2 to the serving cell CGIF of the RAI4, since the location trigger corresponding to the RAI2 is a large granularity location trigger and the location trigger corresponding to the RAI4 is a large granularity location trigger, at the determined location The trigger and the location trigger used by the gateway device configuration belong to the same location trigger, and the determined large-granularity location trigger may be sent to the gateway device, or the determined small-granularity location trigger may not be sent to the location The gateway device sends an authorization response message to inform the gateway device that the location trigger is not changed.

When the terminal device performs handover in the serving cell in the area RAI1 (ie, the control area), the location information needs to be reported in real time, but when the terminal device switches in the serving area in the area RAI2 (ie, the unmanaged area), the location information does not need to be reported in real time. It also does not need to trigger the issuance of the management and control strategy, avoiding the interaction of invalid signaling, saving system resources and improving system performance.
