Description
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a location service configuration method and device.
Background
The third Generation Partnership Project (3rd Generation Partnership Project, 3GPP) discloses a method for location service configuration, and the specific flow is shown in fig. 1:
step 101: a Gateway Mobile Location Center (GMLC) requests Data from a Universal Data Manager (UDM), for example, invokes a numdm UECM Get operation, and obtains user-related Data, for example, original access management function information of a service user, from the UDM.
Step 102: the GMLC requests Location configuration from an Access Management Function (AMF), for example, calls a Request (Request) operation of a naf _ Location _ ProvideProvisioningInfo, and carries a trigger condition for triggering Location service, for example, a period and a terminal reachability.
Step 103: the source AMF determines that a terminal (e.g., User Equipment (UE)) is not reachable, and then waits.
Step 104: the UE moves to a new location and accesses the target AMF at the new location, e.g., sends a Registration Request (Registration Request) message.
Step 105: the target AMF informs the source AMF that the UE has moved, e.g. sends a Request operation calling Namf _ Communication _ UEContextTransfer.
Step 106: the source AMF sends a Location configuration failure to the GMLC, for example, returns a failure indication to the Request operation of the Namf _ Location _ ProvideProvisioningInfo.
Step 107: the GMLC repeats the operation of step 101 to obtain target AMF information of the serving UE.
Step 108: the GMLC requests Location configuration from the target AMF, for example, calls a Request operation of the Namf _ Location _ provideassioninginfo, and carries a trigger condition for triggering Location service, for example, a period and a terminal reachability.
Step 109: the target AMF sends a position configuration initiation Request to the UE, for example, sends an NAS Location Notification Invoke Request message, which carries a trigger condition.
Step 110: the UE sends a Location configuration initiation response, for example, sends a Non-access stratum (NAS) Location Notification call Return Result (Location Notification Invoke Return Result) message.
Step 111: the target AMF returns a result to the GMLC, for example, to the Request operation of the Namf _ Location _ ProvideProvisioningInfo.
When the UE moves to a fourth generation Mobile communication technology (4G) network and is reachable, the target Mobility Management Entity (MME) may not have an interface to notify the source AMF that the UE Location moves (i.e., cannot perform step 105), which may result in that the Gateway Mobile Location Center (GMLC) cannot be triggered to perform the Location service configuration procedure again.

Referring to fig. 4, the specific steps are as follows:
step 401: the GMLC requests data from a subscription service UDM or Home Subscriber Server (HSS).
For example, invoking a Nudm _ UECM _ Get operation to obtain user-related data from the UDM includes: core network function/entity (e.g., source AMF or source MME) information of the serving UE.
Step 402: the GMLC subscribes to Data update requests to a subscription service UDM or a Unified Data Repository (UDR).
For example, invoking the Request operation of Nudr _ DM _ Subscribe, UDR returns the result of the invocation to GMLC.
Step 403: the GMLC requests location configuration from the source core network function (e.g., AMF).
For example, the Request operation of the Namf _ Location _ ProvideProvisioningInfo is called, and the trigger condition for triggering the Location service is carried, such as a period and terminal reachability.
Step 404: the source AMF determines that the UE is not reachable, and then waits.
Step 405: the UE moves to a new location and accesses a target core network function or entity (e.g., AMF or MME) at the new location.
For example, a Registration Request message or an Attach Request (Attach Request) message is sent.
Step 406: the target core network function or entity sends a location update request to the UDM or HSS.
For example, a Nudm _ UECM _ Update operation is called, or an Update Location (Update Location Request) message is sent.
Step 407: the UDM or HSS updates data in the UDR, such as UE location information or UE reachable status, and notifies the GMLC of the data update, such as invoking a Nudr _ DM _ Notify operation, and carries the updated UE location information or UE reachable status information, and further, may also carry target AMF information or target MME information of the serving UE.
Step 408: the GMLC may repeat the operations of step 401 to obtain target AMF information or target MME information for the serving UE.
Step 409: the GMLC determines whether the received information of the core network function/entity (e.g., the target AMF or the target MME) serving the UE is different from that obtained in step 401.
In some embodiment modes, step 409 is an optional step.
If step 409 is performed, and if the determination results are different, then the following steps 410-413 are performed.
If step 409 is not performed, the subsequent steps 410-413 continue to be performed.
Step 410: the GMLC requests location configuration from a target core network function or entity.
For example, a Request operation of the naf _ Location _ ProvideProvisioningInfo is called, or a Location Service Request (LCS Service Request) message is sent, or a provide Subscriber Location (Service Location) message is sent, which carries a trigger condition for triggering a Location Service, such as a period and terminal reachability.
Step 411: and the target AMF or the target MME sends a position configuration initiating request to the UE.
For example, a NAS Location Notification Invoke Request (Location Notification Invoke Request) message or a Location service Periodic (LCS Periodic) -Triggered Event Invoke (Triggered Event Invoke) message is sent, which carries a trigger condition.
Step 412: the UE sends a location configuration initiation response.
For example, a NAS Location Notification Invoke Return Result message or LCS Periodic-Triggered Event Invoke Ack message is sent.
Step 413: the target AMF or target MME returns the result to the GMLC.
For example, a result is returned to the Request operation of the Namf _ Location _ ProvideprovisionInfo, or an LCS Service Response message is transmitted, or a Provide Subscriber Location Ack (Provide Subscriber Location Ack) message is transmitted.
Optionally, the GMLC unsubscribes from the subscription service UDM or UDR for a data update Request, such as a Request operation that calls Nudr _ DM _ ubscript.
In the embodiment of the present invention, the GMLC may subscribe to a data update service from the UDM or UDR, and when the location information of the terminal or the state information of the terminal in the UDM or UDR changes, the UDM or UDR may notify the GMLC of the data update, triggering the GMLC to perform the location service configuration procedure for the terminal again.

These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instruction means which implement the function specified in the flowchart flow or flows and/or block diagram block or blocks.
These computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.
It will be apparent to those skilled in the art that various changes and modifications may be made in the embodiments of the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the embodiments of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to encompass such modifications and variations.
