Description

Location reporting method, device and system

Technical field

The embodiments of the present invention relate to the field of communications technologies, and in particular, to a location reporting method, device, and system. Background technique

In order to meet the challenges of wireless broadband technology and maintain the leading edge of the 3rd Generation Partnership Project (3GPP) network, 3GPP developed the Long Term Evolution (LTE) program at the end of 2004. Under the guidance of the LTE program, a new mobile communication network architecture is defined, which is combined with General Packet Radio Service (GPRS)/Universal Mobile Telecommunications System (UMTS). The 匕 network is also called the Evolved Packet System (abbreviated as EPS).

The structure of the core network of the existing wireless evolved network mainly includes: Mobility Management Entity (MME), Serving Gateway (S-GW), Packet Data Network (Packet Data Network) Gateway; Abbreviation: PDN-GW) Three logical functions. The MME is responsible for the non-access layer (NAS) signaling and NAS signaling encryption, roaming, and tracking functions. The user equipment (User Equipment; UE) temporary identity and security can be assigned. The function corresponds to the control plane part of the Servicing GPRS Support Node (SGSN) in the current UMTS system. The S-GW is responsible for local mobility anchors, mobility anchors within the 3GPP system, and lawful interception related information; the PDN-GW is responsible for policy enforcement, accounting, and lawful interception related functions.

The communication model of the above wireless evolution network is currently mainly applied to human to human (Human to Human; abbreviation: H2H) Communication system, in the H2H communication system, the method of location reporting is: when the user equipment establishes a bearer, the Policy and Charging Rules Function (PCRF) formulates policy control. With Billing (Policy Control and Charging; PCC), the PCC includes subscription events for location change reporting. After obtaining the PCC, the gateway (for example, the GGSN/P-GW) can obtain the subscription event reported by the location change, and the gateway forwards the subscription event reported by the location change to the mobility management network element in the session management response message (for example, SGSN). /MME), the mobility management network element sends a location report control message to the access network element (for example, RNC/eNodeB), and carries the subscription event reported by the location change report in the report control message. After the access network element detects that the location of the user equipment is changed, the event that the location change of the user equipment is reported to the mobility management network element, and the mobility management network element reports the event of the location change of the user equipment to the PCRF through the gateway. This location reporting method relies on the deployment of the PCC architecture, and the reporting event of the PCC subscription user equipment location change depends on the presence of the user equipment bearer.

Machine to Machine (M2M) communication is a network communication between one or more network elements without human intervention, such as traffic control and management, factory monitoring, remote meter reading and other applications. The M2M terminal device can connect to the application server for data communication through the wireless evolution network.

In the existing H2H communication system, when the location of the user equipment changes, the network reports the event of the user equipment location change to the PCRF; according to the requirements of the M2M application, the network only needs to use this when the M2M terminal enters or leaves a specific area. The event is reported to the application server. Therefore, if the location reporting scheme of the H2H communication system is used, the network of the M2M communication system will report a large amount of invalid signaling, resulting in an increase in network load.

In addition, the H2H communication system network can only detect the location change of the user equipment in the connected state, and cannot detect the location change of the user equipment in the idle state. However, in M2M applications, in order to save network resources, many M2M terminals are only attached to the network and do not establish bearers. Therefore, when there is no bearer in the M2M terminal, the M2M terminal is in an idle state, and the H2H pass is used. The location reporting scheme of the letter system cannot be used for location reporting. Summary of the invention

It is obvious that the described embodiments are a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

Embodiment 1

FIG. 1 is a flowchart of a method for reporting a location according to Embodiment 1 of the present invention. The method for reporting a location according to FIG. 1 may include the following steps:

Step 101: Acquire event information for reporting that the user equipment enters or leaves the target location area, where the event information includes location information of the target location area.

The event information may include location information of the target location area, for example: cell information

(Cell Global Identifier or E-UTRAN Cell Global Identifier), Routing Area Identifier (RAI), Tracking Area Identity (TAI), Location Area Identity (referred to as Location Area Identity; LAI), Tracking Area Identity list, access network element identifier, and so on. Optionally, the event information may further include a report type, for example, the user equipment enters the target location area report, the user equipment leaves the target location area report, or the user equipment enters and leaves the target location area report.

In one case, in step 101, if the user equipment is in an idle state or a waiting state, the user equipment acquires the event information, and the network may notify the user equipment of the information of entering or leaving the event. The specific implementation can include the following two methods:

Manner: If the user equipment is in an idle state or a waiting state, the user equipment receives the event information that is sent by the management network element by using a non-access stratum, where the management network element includes a mobility management network. Element (SGSN/MME), Mobile Switching Center (MSC), Visit Location Register (VLR).

Specifically, the user equipment may initiate an update process such as an attach/routing area update/location area update/tracking area update to the network, and manage the network element during the process of the user equipment initiating the foregoing process (for example: The mobility management network element (SGSN/MME), the mobile switching center (MSC) or the visitor location register (VLR) can obtain the subscription data of the user equipment from the subscription database (HLR/HSS). The event information of the user equipment entering or leaving a certain target location area has been signed and signed in the subscription data of the user equipment. After obtaining the event information, the SGSN/MME/MSC/VLR may send the event information to the user equipment. For example: The SGSN/MME/MSC/VLR may send the event information to the user equipment in the attach/routing area update/location area update/tracking area update accept message.

Manner 2: The user equipment receives the event information sent by the application information server. Specifically, after the user equipment is attached to the network, the application information server of the application layer (for example, an Open Mobile Alliance Device Management (OMA DM) server) notifies the user equipment of the event information.

In another case, in step 101, if the user equipment is in the connected state or Ready state, the management network element may be received through the access network element (such as RNC or eNodeB) (for example: mobility management network) The above event information sent by the element).

Step 102: Determine, according to the location information of the user equipment and the location information of the target location area, whether the user equipment enters or leaves the target location area.

In one case, in step 102, if the user equipment is in an idle state or a standby state, the user equipment acquires location information of the user equipment from the broadcast information of the network element of the access network. The user equipment compares the location information of the user equipment with the location information of the target location area in the event information, and determines whether the user equipment enters or leaves the target location area.

Specifically, after the user equipment receives the event information, the user equipment may obtain location information of the target location area in the event information. Moreover, the user equipment can obtain the location information of the user equipment, for example, the location information broadcast by the user equipment through the access network element (which may include cell information, routing area information or tracking area information, location area information, or tracking area list information, etc.) At least one) knows the location information of the user equipment. Then, the user device will be where it is located The information is compared with the obtained location information of the target location area. If the location information of the user equipment and the obtained location information of the target location area are the same, the user equipment enters the target location area; if the location information of the user equipment is The obtained location information of the target location area is different, and the user equipment leaves the target location area. Optionally, the event information may further include a report type, where the report type may include: reporting an event that the user equipment enters the target location area, reporting an event that the user equipment leaves the target location area, or reporting the user equipment entering and leaving the location The event in the target location area. If the user equipment obtains the report type in the event information, the event report is performed only when the report type is met. For example, the report type is an event that reports that the UE enters the "A city", but if the UE is detected to leave the "A city", the event report is not performed.

In another case, in step 102, if the user equipment is in a connected state or a ready state, the access network element stores the location information of the user equipment and the location of the target location area in the event information. The information is compared to determine whether the user equipment enters or leaves the target location area. The specific method for determining whether the user equipment enters or leaves the target location area is similar to that of the user equipment, and is not described herein.

Step 103: If the user equipment enters or leaves the target location area, report the event that the user equipment enters or leaves the target location area to the management network element in the network, so that the management network element performs event reporting. .

In one case, if the user equipment is in an idle state or a waiting state, and the user equipment determines in step 102 that the user equipment enters or leaves the target location area, the user equipment may initiate an access procedure. In the access procedure, The user equipment is transferred to the connection state or the preparation state. The user equipment can send the location information of the user equipment to the SGSN/MME/MSC/VLR through the access network element, and the user equipment obtained by the SGSN/MME/MSC/VLR is located. The location information is compared with the location information of the target location area of the user equipment obtained from the subscription data in step 101. If the reporting condition is met, the SGSN/MME/MSC/VLR performs event reporting to enter or leave the user equipment. The event in the target location area is reported to the application service Server. For example, if the location information of the user equipment and the obtained location information of the target location area of the user equipment are the same, the SGSN/MME/MSC/VLR may determine that the user equipment enters the target location area, then the SGSN/MME/MSC/ The VLR performs an entry event report; if the location information of the user equipment is different from the obtained location information of the target location area of the user equipment, the SGSN/MME/MSC/VLR may determine that the user equipment leaves the target location area, then the SGSN/ The MME/MSC/VLR performs a leaving event report.

In another case, if the user equipment is in a connected state or a ready state, and in step 102, the access network element determines that the user equipment enters or leaves the target location area, the access network element The management network element (for example, a mobility management network element (SGSN/MME)) reports an event that the user equipment enters or leaves the target location area.

In addition, in order to prevent duplicate location reporting, the user equipment may indicate whether the management network element in the network reports an event that the user equipment enters or leaves the target location area. Specifically, the user equipment may send a non-access stratum message carrying the indication information to the mobility management network element, the mobile switching center, or the visitor location register, where the indication information indicates whether the user equipment is allowed to report to enter or leave the target location area. event. The method for setting the indication information by the user equipment may be: if the user equipment enters or leaves the target location area for the first time, the user equipment sets the indication information to report that the user equipment enters or leaves the user equipment. The target location area; if the user equipment does not enter or leave the target location area for the first time, the user equipment sets the indication information to not report that the user equipment enters or leaves the target location area. The user equipment enters the target location area for the first time, specifically: the location where the user equipment is located is changed from the non-target location area to the target location area; the user equipment leaves the target for the first time. The location area is specifically: the location where the user equipment is located is changed from the target location area to the non-target location area.

For example, the user equipment carries the indication information in the access request message to instruct the SGSN/MME/MSC/VLR to perform event reporting. This way the control point is on the user device. The user equipment can know whether it is the first time to enter or leave the target location area, and if so, The user equipment carries the indication information indicating that the SGSN/MME/MSC/VLR performs the event reporting in the access request message; if not, the user equipment does not carry the indication information in the access request message, even if the SGSN/MME/MSC/VLR learns to report The condition is met and the event is not reported.

The above access procedure refers to the transition of the user equipment from the idle state to the connected state or from the waiting state to the ready state, including: in the UMTS Terrestrial Radio Access Network (UTRAN) / evolved UTRAN (Evolved UTRAN) Abbreviation: E-UTRAN ) In the system, the user equipment initiates the service/tracking area update/routing request update service (Service/TAU/RAU Request) procedure, the user equipment changes from the idle state to the connected state; or, the GSM edge wirelessly connects In the GSM EDGE Radio Access Network (GERAN) system, the user equipment sends an uplink packet, and the user equipment changes from the waiting state to the ready state.

In the location reporting method of the embodiment, after the user equipment or the access network element acquires event information for reporting that the user equipment enters or leaves the target location area, the user information may be determined according to the event information and the location information of the user equipment. Whether the device enters or leaves the target location area; if yes, the user equipment or the access network element may report the event that the user equipment enters or leaves the target location area to the management network element in the network, so that the management network The meta-execution event report satisfies the requirement that the application server performs event reporting when the user equipment enters or leaves the target location area, avoids unnecessary signaling, reduces system signaling load, and does not require the user equipment to establish a bearer and maintain the connection state. , alleviating the occupancy of network resources by location reporting.

Embodiment 2

FIG. 2 is a flowchart of a method for reporting a location according to Embodiment 2 of the present invention. As shown in FIG. 2, the method for reporting a location may include the following steps:

Step 201: Send event information for reporting that the user equipment enters or leaves the target location area;

The event information includes location information of a target location area. Before the step 201, the user equipment may be contracted and reported to enter or leave the target in the subscription data of the user equipment. Event information of the location area; the mobility management network element, the mobile switching center, or the visitor location register obtains the event information from the subscription data of the user equipment. The location information of the target location area may include: at least one of cell information, routing area information, tracking area information, location area information, or tracking area list information. Further, the event information further includes a report type, and the report type includes: reporting an event that the user equipment enters the target location area, reporting an event that the user equipment leaves the target location area, or reporting the user equipment entering and leaving the The event in the target location area. For the specific content of the event information, refer to the related description in the first embodiment, and details are not described herein again.

In addition, in the M2M application, the application server can perform location tracking on the M2M terminal: After the M2M terminal enters or leaves the specific tracking area, the network detects the event and reports the event to the application server. After the application server obtains this event, it is learned that the M2M terminal enters or leaves a specific tracking area, and the application server can perform service management or control based on the location of the user equipment according to the events, for example, a location-based push service. If the target location area is a tracking area, the following steps may be included before step 201:

a mobility management entity (MME) transmitting, to the user equipment, a tracking area list including only the tracking area;

After the user equipment enters or leaves the tracking area, the mobility management entity receives the tracking area update message initiated by the user equipment, and determines, according to the tracking area update message, whether the user equipment enters or leaves the tracking area. .

Further, step 201 can be specifically divided into the following cases:

In one case, if the user equipment is in an idle state or a waiting state, the management network element in the network sends the event information for reporting that the user equipment enters or leaves the target location area to the user equipment through the access network element.

In another case, if the user equipment is in a connected state or a ready state, the management network element in the network sends a message to the access network element for reporting that the user equipment enters or leaves the target location area. Event information.

Specifically, the event information may further carry an identifier of an access network element corresponding to the target location area, where the management network element in the network sends an identifier to the access network element corresponding to the identifier of the access network element Event information.

Step 202: Acquire, if the user equipment enters or leaves an event of the target location area, acquiring location information of the user equipment;

The step 202 may specifically include the following situations:

In one case, if the user equipment is in an idle state or a waiting state, the management network element in the network receives, by the access network element, the user equipment reported by the user equipment to enter or leave the target location area. Event; or

In another case, if the user equipment is in a connected state or a ready state, the management network element in the network receives an event that the user equipment reported by the access network element enters or leaves the target location area.

The specific method for the management network element to obtain the location information of the user equipment may be: a management network element, for example: a mobility management network element, a mobile switching center, or a visitor location register may receive the access network element, for example: a base station , the location information of the user equipment that is sent.

Step 203: Perform event reporting according to the location information of the user equipment and the location information of the target location area.

Before the step 203 is performed, the management network element in the network may first determine whether the user equipment enters or leaves the target location area for the first time, and if it is the first time, perform the location report of step 203. . The first time the user equipment enters the target location area is: the location where the user equipment is located is changed from the non-target location area to the target location area; the user equipment leaves the target location for the first time. The area is specifically: the location where the user equipment is located is changed from the target location area to the non-target location area.

The management network element in the network may be set according to its own flag or user equipment. The information is used to determine whether the user equipment enters or leaves the target location area for the first time, and then determines whether to perform event reporting according to whether the user equipment is entering or leaving the target location area for the first time.

For example, the mobility management network element, the mobile switching center, or the visitor location register receives the non-access stratum message carrying the indication information sent by the user equipment, and determines, according to the indication information, whether to report the user equipment entering or leaving the target location area. Event

For example, the user equipment carries the indication information in the access request message to instruct the SGSN/MME/MSC/VLR to perform event reporting. This way the control point is on the user device. The user equipment can know whether it is the first time to enter or leave the target location area. If yes, the user equipment carries the indication information indicating that the SGSN/MME/MSC/VLR performs event reporting in the access request message; if not, then The user equipment does not carry the indication information in the access request message, and the event reporting is not performed even if the SGSN/MME/MSC/VLR learns that the reporting condition is satisfied.

Example 2: The mobility management network element, the mobile switching center or the visitor location register determines whether to report an event of the user equipment entering or leaving the target location area according to a flag bit in the context of the user equipment.

Further, in the second example, if the user equipment enters or leaves the target location area for the first time, the mobility management network element, the mobile switching center, or the visitor location register sets the flag bit to the reporting station. Said user equipment entering or leaving the target location area;

Otherwise, the mobility management network element, the mobile switching center or the visitor location register sets the flag bit to not report that the user equipment enters or leaves the target location area.

For example: The SGSN/MME/MSC/VLR uses the flag bit to record whether the user equipment is entering or leaving the target location area for the first time. Specifically, setting a flag bit in the user equipment context of the SGSN/MME/MSC/VLR records whether the user equipment enters or leaves the target location area for the first time. For example, when the SGSN/MME/MSC/VLR learns that the user equipment enters or leaves the target location area for the first time, the flag bit in the user equipment context may be set to be invalid (for example, set to "0"). Subsequent even if the SGSN/MME/MSC/VLR learns that the user equipment is entering Enter or leave the target location area, that is, the location reporting condition is met, but if the flag is invalid,

The SGSN/MME/MSC/VLR also does not perform event reporting.

The step 203 may specifically include the following steps:

After the mobility management network element, the mobile switching center, or the visitor location register receives the location information of the user equipment sent by the access network element, the mobility management network element, the mobile switching center, or the visited location register is configured according to the The location information of the user equipment and the location information of the target location area in the event information, and the event reporting of the user equipment entering or leaving the target location area is performed.

Specifically, the event management report that the mobility management network element, the mobile switching center, or the visitor location register performs the user equipment to enter or leave the target location area may include: if the location information of the user equipment and the target location in the event information If the location information of the area is the same, the event that the user equipment enters the target location area is reported to the application server; if the location information of the user equipment is different from the location information of the target location area in the event information, the application is applied to the application. The server reports an event that the user equipment leaves the target location area.

The event that the mobility management network element, the mobile switching center, or the visitor location register reports to the application server that the user equipment enters or leaves the target location area may specifically include the following scenarios:

Scenario 1. The mobility management network element, the mobile switching center, or the visitor location register sends a location report message to the application server, where the location report message carries information indicating that the user equipment enters or leaves the target location area, or And sending the location report message to the third-party network element, where the third-party network element sends the location report message or the event message carrying the geographic location corresponding to the target location area to the application server. For example, the SGSN/MME/MSC/VLR sends a location report message, and the location report message is directly sent to the application server or sent to the application server through a third-party network element (for example, a message processing platform). The third-party network element can directly forward the report message to the location, and the third-party network element can also convert the target location area in the location report message into a geographic location, and then the third-party network element reports the user equipment to the application server. An event that enters or leaves the geographic location.

Scenario 2: The mobility management network element sends a location report message to the application server through the gateway, where the location report message carries information indicating that the user equipment enters or leaves the target location area, or reports the location through the gateway. The message is sent to the third-party network element, and the third-party network element sends the location report message or the event message carrying the geographical location corresponding to the target location area to the application server. For example, the SGSN/MME sends a location report message to the gateway (eg, GGSN/PGW), and the gateway sends the location report message to the application server. The gateway may also send the location report message to the third-party network element. And sending, by the third-party network element, the location reporting message to the application server or reporting an event that the user equipment enters or leaves a geographic location corresponding to the target location area.

Scenario 3: The mobility management network element, the mobile switching center, or the visitor location register sends a location report message to the application server through the subscription database, where the location report message carries information indicating that the user equipment enters or leaves the target location area, Or sending the location report message to the third-party network element by using the subscription database, and the third-party network element sends the location report message or the event message carrying the geographical location corresponding to the target location area to the application server. For example, the SGSN/MME/MSC/VLR sends the location report message to the application server through the subscription database (eg, HLR/HSS). The subscription database may also send the location report message to the third-party network element. The third-party network element sends the location report message to the application server or reports an event that the user equipment enters or leaves the geographic location corresponding to the target location area.

In the location reporting method of the embodiment, after the management network element in the network sends event information for reporting the user equipment to enter or leave the target location area, the user equipment or the access network element may be sent to the user equipment or the access network network element. The event information of the user equipment entering or leaving the target location area is reported, and the location information of the user equipment is obtained. Then, the event reporting is performed according to the location information of the user equipment and the location information of the target location area, which satisfies the application server entering or leaving the target device. The requirement of event reporting is performed in the location area, which avoids useless signaling and reduces the system signaling load; and does not require the user equipment to establish a bearer and maintain the connection state, thereby reducing the position. Report the occupation of network resources.

Embodiment 3

FIG. 3 is a flowchart of a method for reporting a location according to Embodiment 3 of the present invention. As shown in FIG. 3, assuming that the user equipment is in an idle state or a standby state, the method for reporting the location may specifically include the following steps.

Step 301: The UE obtains event information for reporting that the UE enters or leaves the target location area, and specifically includes the following manner.

In the first method, the UE initiates an attach process or a routing area/location area/tracking area update process to the network, which may include steps 3011 to 3014.

Step 301 1. The UE sends an attach/track area update/route area update request (Attach/TAU/RAU/LAU Request) message to the SGSN/MME/MSC/VLR.

Step 3012: The SGSN/MME/MSC/VLR sends an update location request (Update Location Request) message to the HLR/HSS to obtain the subscription data of the UE, where the subscription data of the UE may be pre-stored in the HLR/HSS.

Step 3013: The event information of the UE in the HLR/HSS stores event information that reports that the UE enters or leaves the target location area. The event information may include location information of the target location area, for example: cell information (CGI or ECGI) or routing area information (RAI) or tracking area information (TAI) or tracking area list information (TA list) or target location area corresponding Access network element identification, etc. Optionally, the event information may further include a report type, for example, the report is sent to the target location area, reported to the target location area, or reported to and from the target location area. The HLR/HSS may carry the above event information in an Update Location Ack message to the SGSN/MME/MSC/VLR.

Step 3014: The SGSN/MME/MSC/VLR sends an Attach/Routing Area Update/Location Area Update Accept (Attach/RAU/TAU/LAU Accept) message to the UE. The Attach/RAU/TAU/LAU Accept message carries the event information obtained by the SGSN/MME/MSC/VLR in step 3013. Manner 2: The network notifies the UE of the event information by using an application layer. Specifically, after the UE is attached to the network, the network notifies the UE of the event information by using an application information server (for example, an OMA DM server).

Step 302: The UE may determine, according to the obtained event information, whether it enters or leaves the target location area.

Specifically, after obtaining the event information in step 301, the UE may obtain location information of the target location area from the event information, for example, location information broadcast by the UE through the access network element (eg, cell information, routing area information, At least one of tracking area information, location area information, or tracking area list information, etc., to know the location information of the UE. The UE compares the location information of the UE with the obtained location information of the target location area. If the location information of the UE and the obtained location information of the target location area are the same, the UE enters the target location area. If the location information of the UE and the obtained location information of the target location area are different, the UE leaves the target location area. Optionally, the UE may also obtain an access network element identifier corresponding to the reporting type and/or the target location area in the event information.

Step 303: The UE initiates the access, so that the mobility management network element obtains the location information of the UE, and the mobility management network element performs the event reporting according to the location information and the event information of the UE, which may include the following steps 3031 to 3032. :

Step 3031: If the UE detects, according to step 302, that the UE enters or leaves the target location area, the UE initiates an access procedure. Specifically, the UE may send a Service/TAU/RAU/LAU Request message to the SGSN/MME/MSC/VLR through the radio access network RAN. Optionally, refer to the description in step 203 in the second embodiment, the SGSN/MME/MSC/VLR may determine whether to report the event that the UE enters or leaves the target location area according to whether the UE enters or leaves the target location area for the first time. . For example, the UE may carry the indication information in the Service/TAU/RAU/LAU Request message to indicate whether the SGSN/MME/MSC/VLR reports the event that the UE enters or leaves the target location area, and may be reported by default or according to the indication information. The value is determined to be reported. In addition, The SGSN/MME/MSC/VLR may also record in the UE context whether the UE is entering or leaving the target location area for the first time by a flag bit.

Step 3032: The access network element (for example, RNC or eNodeB or BSC) sends the location information of the UE to the management network element. For example: In a UTRAN system, the RNC sends an Initial UE message/Uplink packet to the SGSN or MSC/VLR. In the E-UTRAN system, the eNodeB sends an initial UE message to the MME. The initial UE message may carry cell information (CGI or ECGI) or tracking area (TAI) information of the UE. For example, in the GERAN system, the BSC sends an uplink data packet to the SGSN and carries the cell information of the UE to the SGSN. After receiving the location information of the UE reported by the RAN side, the SGSN/MME/MSC/VLR may compare the location information of the UE and the location information of the target location area obtained in step 301. If they are the same, the UE may enter. The target location area, if different, may indicate that the UE has left the target location area. The SGSN/MME/MSC/VLR determines whether to report an event of the UE entering or leaving the target location area according to the comparison result.

Optionally, if the SGSN/MME/MSC/VLR reports the event that the UE enters or leaves the target location area in the indication information carried in the Service/TAU/RAU/LAU Request message, the step is performed in step 3031. In 3032, the SGSN/MME/MSC/VLR may determine, according to the foregoing comparison result and the indication information, whether to report an event that the UE enters or leaves the target location area; if the UE is in the Service/TAU/RAU/LAU Request message in step 3031 If the SGSN/MME/MSC/VLR does not report the event that the UE enters or leaves the target location area, the SGSN/MME/MSC/VLR does not report or even compares in step 3032.

Alternatively, the SGSN/MME/MSC/VLR may determine whether to report the UE entering or leaving the target location area according to the foregoing comparison result and a flag in the UE context that records whether the UE is entering or leaving the target location area for the first time. event. Specifically, after the SGSN/MME/MSC/VLR learns that the UE enters or leaves the target location area for the first time, The SGSN/MME/MSC/VLR sets the flag bit in the UE context to be invalid (for example, set to "0"). If the SGSN/MME/MSC/VLR learns that the reporting condition is satisfied, but the flag is invalid, the SGSN/MME/MSC/VLR does not perform event reporting. The UE entering the target location area for the first time means that the location of the UE is changed from the non-target location area to the target location area; the first time the UE leaves the target location area means that the location of the UE changes from the target location area to the non-target area. Location area.

Further, if the location information of the target location area in the event information is the tracking area (TA) information, after the MME obtains the event information of the target location area from the subscription data, the MME may allocate a tracking area list (TA list) for the UE. The information only contains the location information of the TA as the target location area. If the UE enters or leaves the TA, the UE actively initiates a Tracking Area Update (TAU) procedure. The MME may determine whether the UE enters or leaves the target location area (ie, the TA) according to the location information of the UE and the TA information learned in the TAU procedure.

Specifically, after the SGSN/MME/MSC/VLR determines that the UE enters or leaves the target location area, the method for performing event reporting may include the following scenarios:

Scenario 1. When the SGSN/MME/MSC/VLR learns that the conditions for reporting are satisfied,

The SGSN/MME/MSC/VLR reports the event that the UE enters or leaves the target location area to the application server, and specifically includes the following steps 3033a to 3035a.

Step 3033a: The SGSN/MME/MSC/VLR sends a Location Report message, where the Location Report message may indicate that the UE enters or leaves the target location area. The SGSN/MME/MSC/VLR may directly send the message to the application server, or the SGSN/MME/MSC/VLR sends the Location Report message to the third-party network element (for example, the M2M platform), and the third-party network The event further reports the event that the UE enters or leaves the target location area to the application server.

Step 3034a: If the SGSN/MME/MSC/VLR first sends the Location Report message to the third-party network element, the third-party network element reports the event that the UE enters or leaves the target location area to the application server after obtaining the Location Report message. Specifically, the third-party network element can Forwarding the Location Report message to the application server, or the third-party network element learns that the UE enters or leaves the target location area according to the Location Report message, and then the third-party network element converts the target location area into a geographical location, and the third-party network The entity reports to the application server an event that the UE enters or leaves the geographic location.

Step 3035a: If the event message sent by the third-party network element to the application server to enter or leave the target location area (the forwarded Location Report message or the reported event of the UE entering or leaving the geographic location), the application server The third party network element sends a Location Report Ack message, and the third party network element sends the Location Report Ack message to the SGSN/MME/MSC/VLR.

If it is sent by the SGSN/MME/MSC/VLR to the application server in step 3033a

The location report message of the UE entering or leaving the target location area, the application server directly therein, the Location Report Ack message may also carry the processing information indicating the SGSN/MME/MSC/VLR to the UE. For example, the UE is separated or the UE is restricted from starting a service or the like.

Scenario 2: The SGSN/MME/MSC/VLR learns that the condition of the report is satisfied, and the SGSN/MME/MSC/VLR reports the event that the UE enters or leaves the target location area to the application server by using the GGSN/PGW, which may include the following step 3033b. Go to step 3036b.

Step 3033b: The SGSN/MME sends a Location Report message, where the message indicates that the UE enters or leaves the target location area. The SGSN/MME sends the message to the GGSN/PGW.

Step 3034b: The GGSN/PGW sends the location report message to the application server, or the GGSN/PGW sends the Location Report message to the third-party network element (for example, the M2M platform), and then the third-party network element enters or leaves the UE. The event in the target location area is reported to the application server. If the GGSN/PGW first sends the Location Report message to the third-party network element, the third-party network element can obtain the Location Report message, and then the UE can enter or The event leaving the target location area is reported to the application server. Specifically, the third-party network element can

The location report message is forwarded to the application server, or the third-party network element learns that the UE enters or leaves the target location area according to the Location Report message, and then converts the target location area into a geographical location, and then reports the UE to enter or leave the application server. The event of the geographic location.

Step 3035b: If the third-party network element sends an event message to the application server to enter or leave the target location area, the application server sends a Location Report Ack message to the third-party network element, and the third-party network element sends the Location Report Ack to the GGSN/PGW. Message.

If the GGSN/PGW sends a Location Report message to the application server to enter or leave the target location area, the application server may directly send a Location Report Ack message to the GGSN/PGW.

The Location Report Ack message may also carry the indication information of the SGSN/MME/MSC/VLR to the UE. For example, the UE is separated or the UE is restricted from starting a service or the like.

Step 3036b: The GGSN/PGW sends a Location Report Ack message to the SGSN/MME.

Scenario 3: The SGSN/MME/MSC/VLR learns that the SGSN/MME/MSC/VLR is satisfied, and the SGSN/MME/MSC/VLR reports the event that the UE enters or leaves the target location area to the application server by using the HLR/HSS, which may include the following step 3033c. Go to step 3036c.

Step 3033c: The SGSN/MME/MSC/VLR sends a Location Report message, where the message indicates that the UE enters or leaves the target location area. The SGSN/MME/MSC/VLR sends the message to the HLR/HSS.

Step 3034c: The HLR/HSS sends the Location Report message to the application server, or the HLR/HSS sends the Location Report message to the third-party network element (for example, the M2M platform), and then the third-party network element enters or leaves the UE. The event in the target location area is reported to the application server. If the HLR/HSS first sends a Location Report message to a third-party network element, then After the third-party network element obtains the Location Report message, the third-party network element reports the event that the UE enters or leaves the target location area to the application server. Specifically, the third-party network element may forward the Location Report message to the application server, or the third-party network element learns that the UE enters or leaves the target location area according to the Location Report message, and then the third-party network element converts the target location area. For the geographic location, the third-party network element reports to the application server an event that the UE enters or leaves the geographic location.

Step 3035c: If the third-party network element sends an event message (the event of forwarding the Location Report message or reporting the UE entering or leaving the geographic location) to the application server, the application server sends the third-party network element to the third-party network element. The Location Report Ack message is sent, and the Location Report Ack message is sent by the third party network element to the HLR/HSS.

If the HLR/HSS sends an event message to the application server to enter or leave the target location area in step 3034c, the application server sends a Location Report Ack message directly to the HLR/HSS.

Step 3036c: The HLR/HSS sends a Location Report to the SGSN/MME/MSC/VLR.

Ack message.

Step 304: The SGSN/MME/MSC/VLR sends a Service Request/Tracking Area Update/Routing Area Update Accept (Service/TAU/RAU/LAU Accept) message to the UE. It is only an example, and other message names may also be used, which are not limited in the embodiment of the present invention.

In the location reporting method of this embodiment, if the UE is in an idle state or a Standby state, the UE may obtain the event information for reporting the entry or exit of the target location area from the SGSN/MME/MSC/VLR, and may be based on the event information. The location information of the target location area and the location information of the acquired UE determine whether the UE enters or leaves the target location area; If yes, the UE may initiate an access to the SGSN/MME/MSC/VLR. After the UE transitions to the connected state or the Ready state, the SGSN/MME/MSC/VLR may perform an event by using the location information of the root target location area and the location information of the UE. The report satisfies the requirement that the application server performs event reporting when the UE enters or leaves the target location area, avoids useless signaling, and reduces system signaling load; and does not require the UE to establish a bearer and maintain the connection state, thereby reducing the location report. The occupation of network resources.

Embodiment 4

4 is a flowchart of a method for location reporting according to Embodiment 4 of the present invention. It is assumed that in a scenario where the UE is in a connected state, where the UE is in a connected state, the UE transitions from an idle state to a connected state after the UE initiates the access. Or the UE changes from the Standby state to the Ready state. As shown

As shown in FIG. 4, the specific method for the network to report the event that the UE enters or leaves the target location area to the application server may include the following steps:

Step 401: The UE initiates an access, where the SGSN/MME obtains the subscription data of the UE. The subscription data of the UE includes event information for reporting that the UE enters or leaves the target location area. For the specific content of the event information, refer to the related description in the first embodiment. The step of acquiring the event information by the SGSN/MME in the access process may specifically include the following steps: 401 1 to the step

4014:

Step 401: The UE sends an Attach/TAU/RAU Request message to the SGSN/MME.

Step 4012: The SGSN/MME sends an update location request to the HLR/HSS (Update

Location Request) message, obtain the subscription data of the UE.

Step 4013: The HLR/HSS sends an Update Location Ack message to the SGSN/MME, where the Update Location Ack message includes the subscription data of the UE, where the subscription data includes the event information.

Step 4014: The SGSN/MME sends an attach/tracking area update/routing area update acceptance to the UE.

( Attach/TAU/RAU Accept ) message. Step 402: After the UE initiates the access, the UE initiates the connection establishment, and changes from the idle state to the connected state or from the Standby state to the Ready state, and the specific UE may send the service/tracking zone update/routing area update request to the SGSN/MME. (Service/TAU/RAU Request) message. The UE may send the Service/TAU/RAU Request message to the RAN first, and the RAN forwards the Service/TAU/RAU Request message (included in the Initial UE message) to the SGSN/MME.

Step 403: The SGSN/MME sends a Location Report Control message carrying the event information to the RAN.

Step 404: The RAN sends a Location Report message to the SGSN/MME to report an event that the UE enters or leaves the target location area.

Specifically, the SGSN/MME may obtain, according to step 401, event information that reports that the UE enters or leaves the target location area. After the UE enters the connection state through step 402, the SGSN/MME sends the event information to the RAN. In the scenario where the UE is in the connected state, the RAN learns that the UE enters or leaves the target location area, and enters or leaves the UE. The event in the target location area is reported to the SGSN/MME. Specifically, the SGSN/MME sends a Location Report Control message to the RNC or the eNodeB, where the Location Report Control message includes the event information. When the UE is in the connected state, the RAN detects whether the UE enters or leaves the target location area according to the obtained event information. If the RAN detects that the UE enters or leaves the target location area, the RAN reports the UE entry to the SGSN/MME. Or an event that leaves the target location area. For example, in the UTRAN system, the RNC detects that the UE enters or leaves the target location area (for example, a certain cell), and the RNC reports to the SGSN that the UE enters or leaves the target location area. For example, in the E-UTRAN system, the eNodeB detects that the UE enters or leaves the target location area (for example, a certain cell or a tracking area), and the eNodeB reports to the MME that the UE enters or leaves the target location area.

When the RAN of the UE access changes due to UE mobility, the SGSN/MME needs to be new

The RAN sends the event information, specifically, the SGSN/MME can switch in the handover process. The event information is sent to the RAN in a message such as a Handover Request/Relocation Request/Path Switch Request.

The SGSN/MME may also send the event information to the RAN in an initial UE context setup or an air interface access allocation request (RAB assignment Request) message in the Service/TAU/RAU Request procedure.

In addition, in this embodiment, preferably, the SGSN/MME may select a part of the RAN to send the event information. Specifically, since the target location area in the event information is a fixed target location area, only a part of the RAN side device can cover the target location area. When the UE accesses the network on the other RAN side device, the SGSN/MME can learn that the UE is not in the range of the target location area, and may not instruct the RAN side device to detect whether the UE enters or leaves the target location area. The SGSN/MME sends the event information to the RAN side devices only when the UE accesses the RAN side device that can cover the target location area, and the RAN side device detects whether the UE enters or leaves the device. Target location area. Specifically, the event information that is contracted in the subscription data may include not only the location information of the target location area, but also the reporting type, and may also include the RAN side device (ie, the access network element) corresponding to the target location area. Information, such as: Access network element identifier (RNC ID or eNodeB ID, etc.). When the UE accesses from the RAN, the RAN side device may carry the access network element identifier in a message and send it to the SGSN/MME. The SGSN/MME compares the access network element identifier sent by the RAN side device with the access network element identifier in the event information. If they are the same, the SGSN/MME notifies the event information to the RAN through the foregoing process. Side equipment. After the RAN side device learns the event information, it detects that the UE enters or leaves the target location area according to the foregoing method. If yes, the event that the UE enters or leaves the target location area is reported to the SGSN/MME.

Step 405: After receiving the Location report message sent by the RAN, the SGSN/MME may enter or leave the target location area on the SGSN/MME. For a specific method, reference may be made to the third step 303 of the embodiment and the description of the three scenarios in FIG. In the location reporting method of this embodiment, if the UE is in the connected state or the Ready state, the RAN may obtain the event information for reporting the entry or exit of the UE into the target location area from the SGSN/MME, and may be based on the target location area in the event information. The location information and the location information of the UE detected by the RAN determine whether the UE enters or leaves the target location area; if yes, reports the event that the UE enters or leaves the target location area to the SGSN/MME, and the SGSN/MME obtains from the RAN. The location information of the UE is used to perform event reporting according to the location information of the target location area and the location information of the UE, which satisfies the requirement that the application server performs event reporting when the UE enters or leaves the target location area, thereby avoiding useless signaling and reducing System signaling load.

A person skilled in the art can understand that all or part of the steps of implementing the above method embodiments may be completed by using hardware related to program instructions, and the foregoing program may be stored in a computer readable storage medium, and the program is executed when executed. The method includes the steps of the foregoing method embodiments.
