 Example 1

 Referring to FIG. 1, this embodiment provides a method for detecting a change of a user's location. The method may be performed by a subscription database or a third-party network element. The method includes:

 S11: The PLMN (Public Land Mobi-communication Network) accessed by the UE (User Equipment) is known.

 S12: According to the PL MN accessed by the UE, the location area corresponding to the PL MN is provided to the network, so that the network learns that the UE enters or leaves the location area corresponding to the PLMN according to the location area corresponding to the PL MN and the current location of the UE.

 The entity corresponding to the network may be a mobility management network element, an MSC, or a VLR, and the mobility management network element is an SGSN or an MME.

 The current location of the user may be a routing area, a tracking area, a tracking area list, or a cell.

 In this embodiment, the location area corresponding to the PLMN is provided to the network by using the PL MN accessed by the UE, so that the network determines, according to the location area corresponding to the PLMN and the current location of the UE, that the user enters or leaves the PLMN. Location area. Example 2

Referring to FIG. 2, this embodiment provides a method for detecting a change of a user's location. The method may be performed by a mobility management network element, an MSC, or a VLR. The mobility management network element is an SGSN or a 匪E. The method includes: S21: Obtain a location area corresponding to the public land mobile communication network PL MN accessed by the user equipment UE. S22: Obtain, according to the location area corresponding to the PLMN and the current location of the UE, the UE enters or leaves the location area corresponding to the PLMN.

 The current location of the user may be a routing area, a tracking area, a tracking area list, or a cell.

 In this embodiment, the location area corresponding to the PL MN accessed by the UE is obtained, according to the location area corresponding to the PL MN and the location area.

The current location of the UE determines that the user enters or leaves the location area corresponding to the PLMN. Example 3

 Referring to FIG. 3, this embodiment provides a method for detecting a change of a user's location. In this method, the subscription database does not subscribe to a location area corresponding to a PLMN that all UEs can access, and needs to store a PLMN corresponding to all UEs that can be accessed. The third-party network element in the location area obtains the location area corresponding to the PLMN identifier, and the method includes:

 101: The UE sends an access request message to the SGSN/MME/MSC/VLR.

 The access request message may be an Attach/TAU (Trace Area Update)/RAU (Routing Area Update)/LAU (Location Area Update) Request message. . "/" means "or".

 102: The SGSN/MME/MSC/VLR sends an update location request Update Location Request message to the subscription database, where the message carries the PLMN identity of the UE accessing the PLMN.

 Among them, the contract database is HLR/HSS.

 After receiving the update location request message, the subscription database sends a notification request Notification Request message to the third-party network element, where the message carries the PLMN identity of the UE accessing the PLMN.

 104: The third-party network element queries the location area corresponding to the PLMN identifier of the PLMN that the UE accesses according to the location area corresponding to the PL MN that all the UEs can access.

 The third-party network element sends a notification confirmation ACK message to the subscription database, where the message carries the location area corresponding to the PLMN accessed by the UE.

 Specifically, the third-party network element notifies the location area corresponding to the PLMN accessed by the UE to the location database through the subscription database.

SGSN/MME/MSC/VLR. For example, the third-party network element may encapsulate the location area corresponding to the PLMN accessed by the UE in a cell transparent to the subscription database. The so-called "cell transparent to the subscription database" means that the subscription database does not need to parse the cell. Only the cell needs to be sent to the subsequent network element SGSN/MME/MSC/VLR. Wherein, the cell can be a transparent container Transparent container ₀

Further, the third-party network element may also indicate the reporting type to the subscription database in the message, and the reporting type includes, but is not limited to, reporting the user entering the location area, reporting the user leaving the location area, and reporting the user entering and leaving the location area. area.

 106: The subscription database sends an update location confirmation Update Location ACK message to the SGSN/MME/MSC/VLR, where the message carries the location area corresponding to the PLMN accessed by the UE.

 Further, the subscription database may also indicate the report type to the SGSN/MME/MSC/VLR in the message.

 The SGSN/MME/MSC/VLR sends an access confirmation message to the UE, where the message carries the location area corresponding to the PL MN that the UE accesses.

 The access confirmation message may be an Attach/TAU/RAU/LAU Accept message. Further, the SGSN/MME/MSC/VLR may also indicate the reporting type to the UE in the message.

 It should be noted that, in this embodiment, the name of the message is not limited, and may be a message named in this embodiment, or may be a message of another name.

 After the steps 101-107, the third-party network element learns the PL MN accessed by the UE, and provides the location area corresponding to the PLMN to the network (SGSN/MME/MSC/VLR). Subsequently, the network determines, according to the location area corresponding to the PLMN and the current location of the UE, that the UE enters or leaves the location area corresponding to the PLMN (not shown in FIG. 2), which specifically includes:

 1) When the UE is in the connected state or the Ready state, the SGSN/MME/MSC/VLR obtains the current location of the UE from the access network element, and compares the current location of the UE with the PLMN accessed by the UE. Whether the location area is the same or included in the location area, if yes (ie, the same or included in the location area), determining that the UE enters the location area corresponding to the PL MN, if no (ie, different or not included in the location area), determining The UE leaves the location area corresponding to the PL MN.

 The SGSN/MME/MSC/VLR obtains the current location of the UE from the access network element, including: under the GERAN (GSM EDGE Radio Access Network, GSM EDGE Radio Access Network) system, BSC (Base Station Control ler, The base station controller reports the current cell information of the SGSN UE, and the RNC (Radio Network Controller) reports the current information to the SGSN UE under the UMRAN (UMTS Terrestrial Radio Access Network) system. In the E-UTRAN (Evolved UTRAN) system, the eNodeB (Evolved Node B) reports the tracking area information or cell information currently logged by the MME UE; or, SGSN/ The MME/MSC/VLR learns the current location RA or TA of the UE according to the RA (Route Area) list or the TA (Trace Area) list that is allocated to the UE.

2) When the UE is in the idle state or the standby state, the UE compares whether the location where the UE is currently located and the location area corresponding to the PLMN accessed by the UE are the same or included in the location area, if yes (ie, the same or included in the location) a location area), determining that the UE enters the location area corresponding to the PL MN, and if not (ie, different or not included in the location area), determining that the UE leaves the location area corresponding to the PLMN. The UE obtains the current location of the UE by using location information (such as cell information, routing area information, or tracking area information, etc.) broadcasted by the access network element. After the UE learns that it enters or leaves the location area, the UE initiates an access procedure to notify the network UE to enter or leave the location area. The access procedure causes the UE to change from the idle state to the connected state, or from the Standby state to the Ready state, and then the SGSN/MME/MSC/VLR can perform the same operations as in 1), and details are not described herein again. The access flow example may be a process such as RAU, TAU, LAU, Service Request.

 After the UE learns that it enters or leaves the location area, the UE initiates an access procedure, including:

 The first method: If the network does not indicate the reporting type to the UE, the UE initiates an access procedure to the SGSN/MME/MSC/VLR when the UE enters and/or leaves the location area corresponding to the PLMN.

 The UE initiates an access procedure to the SGSN/MME/MSC/VLR when the UE enters or/and leaves the location area corresponding to the PL MN. Specifically, when the UE enters the location area corresponding to the PL MN, the UE sends the SGSN to the SGSN/ The MME/MSC/VLR initiates an access procedure; or, when the UE leaves the location area corresponding to the PL MN, the UE initiates an access procedure to the SGSN/MME/MSC/VLR; or, when the UE enters the location area corresponding to the PLMN, and When the UE leaves the location area corresponding to the PLMN, the UE initiates an access procedure to the SGSN/MME/MSC/VLR.

 The second method: If the network indicates the reporting type to the UE, when the UE enters the location area corresponding to the PL MN and the reporting type is that the UE enters the location area, or when the UE leaves the location area corresponding to the PLMN and the reporting type is reported by the UE leaving The UE initiates an access procedure to the SGSN/MME/MSC/VLR when the UE enters or leaves the location area corresponding to the PLMN and the reporting type is to report the UE entry and exit location area.

 The third method: the UE saves the location where the UE was last (the last location of the UE refers to the location of the UE indicated by the network (SGSN/MME/MSC) to the UE in the mobility management procedure; or the UE monitors Location of the network broadcast), if the network does not indicate the reporting type to the UE, when the UE determines that the incoming access condition or/and the leaving access condition is met, the UE initiates an access procedure to the SGSN/MME/MSC/VLR; The UE indicates the reporting type, when the UE determines that the access condition is met, and the reporting type is that the reporting UE enters the location area, or when the UE determines that the leaving access condition is met, and the reporting type is reporting the leaving location area of the UE, or when the UE determines The UE initiates an access procedure to the SGSN/MME/MSC/VLR when the access conditions are met or the access conditions are met, and the reporting type is to report the entry and exit locations of the UE.

 The access access condition is: after the UE determines that it enters the location area (that is, the location where the UE is currently located is the same as or included in the location area corresponding to the PLMN accessed by the UE), if the UE is located last time The UE initiates an access procedure to the SGSN/MME/MSC/VLR to notify the network UE to enter the location area, or is not included in the location area.

The leaving access condition is: after the UE determines that it leaves the location area (that is, the location where the UE is currently located is different from or not included in the location area corresponding to the PLMN accessed by the UE), if the UE is located last time If the location is the same as or included in the location area, the UE initiates an access procedure to the SGSN/MME/MSC/VLR to notify the network UE to leave the location area. The foregoing third method can prevent the UE from repeatedly initiating the access procedure, thereby avoiding repeatedly reporting the network UE to enter or leave the location area. For example, when the UE moves in the location area, the location where the UE last stored in the UE is the same as or included in the location area, the UE knows that the current location of the UE is the same as or contains the location area. In the location area, the UE does not initiate an access procedure. For another example, when the UE moves outside the location area, the UE saves that the location where the UE was last and the location area is different or not included in the location area, and the UE knows that the current location of the UE is different from the location area or It is not included in the location area, and the UE does not initiate the access procedure.

 Further, after the network (SGSN/MME/MSC/VLR) determines that the UE enters or leaves the location area corresponding to the PLMN according to the location area corresponding to the PLMN and the current location of the UE, the UE may enter or leave the location corresponding to the PLMN. The events of the area are reported to the application server (or other network elements except the application server), and the application server (or other network element) can perform corresponding service management and control according to the event.

 The network reports the event that the UE enters or leaves the location area corresponding to the PLMN to the application server (or other network element except the application server), including:

 The first method: if the network does not receive the reporting type, when it is determined that the UE enters or/and leaves the location area corresponding to the PL MN, the network reports an event that the UE enters or leaves the location area corresponding to the PLMN;

 The second method: if the network receives the report type, when it is determined that the UE enters the location area corresponding to the PL MN and the report type is that the UE enters the location area, the network reports that the UE enters the location area corresponding to the PL MN; or when determining When the UE leaves the location area corresponding to the PLMN and the reporting type is that the UE leaves the location area, the network reports that the UE leaves the location area corresponding to the PLMN; or when it is determined that the UE enters or leaves the location area corresponding to the PLMN, and the reporting type is reported to the UE. And leaving the location area, the network reports an event that the UE enters or leaves the location area corresponding to the PLMN;

 The third method: The network saves the last location of the UE (the location of the UE where the network is last stored refers to the location of the UE saved in the UE context in the network (SGSN/MME/MSC)), if the network does not report to the UE Type, when it is determined that the UE meets the conditions for entering the report or/and the condition for leaving the report, the network reports an event that the UE enters or leaves the location area corresponding to the PLMN;

 If the network indicates the reporting type to the UE, when it is determined that the UE meets the reporting condition, and the reporting type is that the reporting UE enters the location area, the network reports that the UE enters the location area corresponding to the PL MN; or when the UE determines that the leaving reporting condition is met, And the reporting type is an event that reports that the UE leaves the location area corresponding to the PL MN when the UE leaves the location area; or when the UE determines that the entry reporting condition or the leaving reporting condition is met, and the reporting type is reporting the UE entering and leaving the location area, The network reports an event that the UE enters or leaves the location area corresponding to the PLMN.

The condition for entering the report is: after determining that the UE enters the location area (that is, the location where the UE is currently located is the same as or included in the location area corresponding to the PL MN accessed by the UE), if the location of the UE last time is The location If the area is different or not included in the location area, the network reports an event that the UE enters the location area corresponding to the PLMN. The leaving reporting condition is: after determining that the UE leaves the location area (ie, the location where the UE is currently located and the UE accessing) If the location of the last location of the UE is different or not included in the location area, if the last location of the UE is the same as or included in the location area, the network reports an event that the UE leaves the location area corresponding to the PLMN.

 The third method described above can prevent the network from repeatedly reporting the event that the UE enters or leaves the location area. For example, when the UE moves within the location area, the last location of the UE saved in the network is the same as or included in the location area, and the network knows that the current location of the UE is the same as or contains the location of the UE. In this location area, the network will not initiate the escalation process. For another example, when the UE moves outside the location area, the last location of the UE saved in the network is different from or not included in the location area, and the network knows the current location and location of the UE. If the area is different or not included in the location area, the network will not initiate the reporting process.

 In this embodiment, the location area corresponding to the PLMN is provided to the network by using the PL MN accessed by the UE, so that the network determines, according to the location area corresponding to the PLMN and the current location of the UE, that the user enters or leaves the PLMN. Location area. At the same time, only the third-party network element stores the location area corresponding to the PLMN that all UEs can access, and the SGSN/MME/MSC/VLR does not need to be stored, which reduces the redundant information existing in the network, and when the UE is in multiple PLs When roaming, the location area corresponding to the PL of other carriers is not required in the subscription database of the home PL of the UE, which reduces the operation and maintenance cost of the network. Example 4

 Referring to FIG. 4, this embodiment provides a method for detecting a change of a user's location. In the method, a location area corresponding to a PL that is accessible to all UEs is signed in the subscription database, and the method includes:

 201: The UE sends an access request message to the SGSN/MME/MSC/VLR.

 The access request message may be an Attach/TAU/RAU/LAU Request message. "/" means "or".

 202: The SGSN/MME/MSC/VLR sends an update location request Update Location Request message to the subscription database, where the message carries the PLMN identity of the UE accessing the PLMN.

 Among them, the contract database is HLR/HSS.

 203: After receiving the update location request message, the subscription database obtains a location area corresponding to the PLMN identity of the UE accessing the PLMN according to the location area corresponding to the PL MN that the UEs can access.

 204: The subscription database sends an update location confirmation Update Location ACK message to the SGSN/MME/MSC/VLR, where the message carries the location area corresponding to the PLMN accessed by the UE.

Further, the subscription database may also indicate the reporting type to the SGSN/MME/MSC/VLR in the message, and the reporting is performed. Types include, but are not limited to, reporting the user's entry into the location area, reporting the user's departure location area, and reporting the user's entry and exit location areas.

 205: The SGSN/MME/MSC/VLR sends an access confirmation message to the UE of the user, where the message carries the location area corresponding to the PLMN accessed by the UE.

 The access confirmation message may be an Attach/TAU/RAU/LAU Accept message. further,

The SGSN/MME/MSC/VLR may also indicate the reporting type to the UE in the message.

 It should be noted that, in this embodiment, the name of the message is not limited, and may be a message named in this embodiment, or may be a message of another name.

 After the steps 201-205, the subscription database learns the PL MN accessed by the UE, and provides the location area corresponding to the PLMN to the network (SGSN/MME/MSC/VLR). Subsequently, the network learns that the UE enters or leaves the location area corresponding to the PLMN according to the location area corresponding to the PLMN and the current location of the UE (not shown in FIG. 3). For details, refer to Embodiment 2.

 Further, after the network (SGSN/MME/MSC/VLR) learns that the UE enters or leaves the location area corresponding to the PLMN according to the location area corresponding to the PLMN and the location of the UE, the UE may enter or leave the location area corresponding to the PLMN. The event is reported to the application server (or other network elements except the application server). For details, refer to implementation 2. The application server (or other network element) can perform corresponding service management and control according to the event.

 In this embodiment, the location area corresponding to the PLMN is provided to the network by using the PL MN accessed by the UE, so that the network determines, according to the location area corresponding to the PLMN and the current location of the UE, the UE enters or leaves the location corresponding to the PLMN. region. At the same time, only the subscription database is used to store the location area corresponding to the PLMN that all UEs can access. The SGSN/MME/MSC/VLR does not need to be stored, which reduces the redundant information existing in the network and reduces the operation and maintenance cost of the network. Example 5
