7 illustrates an example of a format of a Stopping LCS area Event message according to an embodiment of the present invention.

The technical field of the present invention relates to a Deferred service (or triggered service) which is a type of location based service. Deferred service is the location service requester (Lequstor) to the location server (Target terminal which is the entity to be located) to track the location of the target terminal (Duration) for a specific period (Duration) suggested by the location service requester Conditions or criteria which are a the UE available event, an Change of area event or a period event.The UE available event is to the area event is the leaving event from the special area, entering event into the area .The period event is done according to the time period like per an hour or three hours.)

The Location server sends a notification to the target terminal before starting the Deferred service. Notification is a message sent by the location server to the target terminal. This message includes the type of location request, the identity of LCS client (Location client: entity requesting deferred service to the location server on behalf of the requester's request, eg mobile carrier), the identity of requestor and information of privacy verification. Includes whether or not to receive from the requestor.

Therefore, the location server can know whether to execute the deferred service from the user of the target terminal. When the user of the target terminal receives a message (notification return, 3GPP 23.271 V6.00 52 page step 5), the location server starts the deferred service, and the target terminal performs the location measurement according to the specific condition suggested by the requester. do.

1 illustrates the prior art.

Description of FIG. 1 is as follows. (Note: 3gpp TS 23.271 V6.10.0 Chap 9.1.9). 1 illustrates a deferred service in a case where a target terminal is in a visited network.

1) The LCS service Request message indicates the change of area type (specific information of the ig target area) nature of event (representing leaving event or entering event or within event), validity time (ie start time, stop time), minimum interval time Between area event report, deferred area Contains information indicating whether to finish the event report once and report multiple times. The Requesting Gateway Mobile Location Center (R-GMLC) converts the target area (i.e. when the target area is indicated by phone number) into a geographical area (longitude, latitude value). The R-GMLC includes the Location Deferred Request (LDR) reference number in the LCS Service Request message. The home address is also included in this message.

2) LCS service request handling between GMLCs is described in 3GPP TS 23.271 V6.10.0 Chap 9.1.1. The LCS Service Request message delivered to the R-GMLC is delivered to the V-GMLC (Visited Gateway Mobile Location Center) through the H-GMLC.

3) V-GMLC converts the target area to Cell identities, location areas or routing areas. The V-GMLC sends the above conversion information (Cell identities, location area or routing area) to the MSC / SGSN (Mobile services Switching Center / Serving GPRS Support Node) together with the information contained in the LCS Service Request message.

4) The MSC / SGSN checks the UE capability to determine whether it supports a change of area event. If the UE is in idle mode, paging, authentication, ciphering is performed. If privacy notification is required, the MSC / SGSN sends an LCS Location Notification Invoke message to the target UE and asks the target UE if it needs privacy verification. A detailed description of the LCS Location Notification can be found in 3GPP TS 23.271 V6.10.0 Chap 9.1.2 and 9.1.6. If privacy verification is required, the UE notifies the MSC / SGSN by sending an LCS Location Notification Return message indicating whether to reject or accept the deferred service request.

5) MSC / SGSN informs the UE of the LCS Area Event. At this time, a cell identities or location area or routing area indicating a target area, a Location Deferred Request (LDR) reference number, and an H-GMLC address are transmitted to the UE. In addition, nature of event (leaving or entering or inside), minimum interval time between area event reports and the type of deferred event (indicating whether to send a report only once or terminate or report multiple times) are also sent to the UE.

6) When the UE successfully receives the LCS Area Event Invoke from the MSC / SGSN, the UE sends an LCS Area Event Invoke ack.

7) MSC / SGSN sends provide subscriber location ack to V-GMLC and records charging information for successfully approved area event.

8) To 10) The V-GMLC informs the LCS client of the LCS Service Response via H-GMLC and R-GMLC whether the request has been successfully approved.

11) The UE determines that an area event has occurred.

12) If an area event occurs, use a CS (Circuit switched) radio connection or a PS (Packet switched) radio connection to report on this. The detailed description is replaced by references of 3GPP TS 23.271 V6.10.0 Chap 9.2.1 and 9.2.2.

13) The MSC / SGSN sends a subscriber location report to the V-GMLC.

14) V-GMLC sends LCS service response to H-GMLC.

15) If the UE moves to the new PLMN, the H-GMLC sends the original area event request to the new V-GMLC of the PLMN where the UE is located.

16) H-GMLC inspects privacy. 9.1.1

17) H-GMLC sends LCS Service Response to R-GMLC.

18) R-GMLC sends LCS Service Response to LCS client.

The problem with the prior art is that when the user of the target terminal allows the deferred service to the location server and then the user of the target terminal tries to stop the deferred service in the middle of the deferred service. The user of the target terminal can grant or deny the Deferred service to the location server before starting the Deferred service. However, when the user of the target terminal attempts to stop the Deferred service previously authorized for any reason, there is no way to do it in the prior art.

An object of the present invention is to provide a method for stopping the ongoing Deferred service according to the user's intention of the target terminal.

The configuration of the present invention is based on Figs. 1 and 1 described in the prior art, and shows that a deferred service stop request is received from a target terminal while the deferred service is in progress, and the deferred service is terminated. The following description describes the entities used in the prior art. The detailed description is therefore described in 3 gpp TS 23.271 V6.10.0 Chap 9.1.9.

The client requests the deferred service from the location server on behalf of the requestor (the originating eneity which has requested the location of target UE (User entity)) requesting the deferred service, and receives the response.

Requesting Gateway Mobile Location Center (R-GMLC) means GMLC where the Client exists.

The H-GMLC is a GMLC existing in the network where the target terminal is registered.

The HLR / HSS (Home Location Registor / Home Subscriber Server) delivers the address of the Serving GPRS Support Node (SGSN) and the VMSC / MSC (Visited Mobile Switching Center) server to the R_GMLC. It also delivers the address of the PPR (Privacy Profile Register), which stores the privacy profile of the target terminal.

V-GMLC represents GMLC of the visited network where the target terminal exists.

The MSC / SGSN performs paging and authentication when the target terminal establishes a CS / PS (Circuit switched, Packet switched network) connection, and sends a notification to the UE.

The RAN makes a radio connection with the UE.

The UE receives a notification from the MSC / SGSN, decides whether to allow or deny the deferred service, and sends the result to the MSC / SGSN. If the Deferred service is allowed, it determines whether an area event has occurred and if so, informs the MSC / SGSN. While the deferred service is in progress, the UE may send a message to the MSC / SGSN that may terminate the deferred service.

2 is a roaming case in which the target terminal exists in the visited network, and is a deferred service capable of tracking location information of the target terminal at regular time intervals. The UE also plays a role in determining whether an area event has occurred. 2 illustrates a process in which the UE initially accepts the deferred service and stops the deferred service that the UE is in progress while the location server is performing the deferred service.

Processes 1 to 18 are the same as those in the prior art drawing 1. Operation 1 ~ 10 is the process of receiving service permission from client to UE to start deferred service, and process 11 ~ 27 is deferred service. 11-18 indicate the first deferred service. 18 is the first LCS service response of the Deferred service. The 18 LCS service response message contains a type of change area event (either Entering or Leaving or Inside). 19 to 27 represent the second deferred service. 27 represents the second LCS service response of the deferred service. The LCS service response message of 27 contains a type of change area event (either Entering, Leaving, or Inside), as in number 18.

28 indicates that a stop request of the deferred service occurs inside the UE while the deferred service is in progress. This request is caused by the intention of the user of the UE. (Reference Drawing 5)

In this case, when the UE receives the LCS Area Event Invoke through 5 of FIG. 1, the UE outputs FIG. 3 to the screen and asks the UE user whether the deferred service is allowed (3 in FIG. 3). The contents of the notification can be displayed on the screen (2 in Fig. 3). While receiving the deferred service from the UE user, while the deferred service is in progress, an indication indicating that the deferred service as in FIG. 4 is in progress may appear on the screen of the UE. On the contrary, if the UE itself can determine whether to stop or continue the deferred service currently in progress according to the privacy profile of the UE user, the UE may send a message to stop the deferred service in progress. In this case, the user has previously set a privacy condition for permission or denial of the deferred service to a part of the UE's memory. At this time, if there is no UE permission request part as shown in 3 of FIG. 3 and the requested deferred service matches the privacy condition set by the UE user, the deferred service is started and the progress is displayed on the screen as shown in 1 of FIG. Can be displayed.

When the stopping area deferred service occurs in the UE, the UE performs process 29 to request the MSC / SGSN to stop the ongoing deferred service. (29 courses). When the MSC / SGSN receives the Stopping Deferred Service Request, it performs process 30a and indicates the deferred service stop request in the Subscriber Location Report message. 30b sends an ack to the V-GMLC that it received the message correctly.

31 informs the H-GMLC that the deferred service has been suspended.

32 H-GMLC informs R-GMLC that the Deferred service has been suspended.

33 indicates that the Deferred service has been stopped by the R-GMLC.

6 shows an operation sequence of a UE. The UE checks whether it has received an LCS area Event Invoke message (2 in Fig. 6). If the message is received (step 5 in Fig. 2), the UE requests the command of the UE user to determine whether to allow or deny the LCS area Event Invoke, or the UE user in advance in the UE Judging according to the privacy profile set (3 in Fig. 6). A message indicating permission or denial of the message is sent to the LCS area Event Invoke ack (6 in Fig. 2). If the denial is sent to the LCS area Event Invoke ack (6 in Fig. 2), it is the fourth step of Fig. 6. At this time, the UE returns to step 2 of FIG. 6 and waits for a new LCS area Event Invoke. If permission is sent to the LCS area Event Invoke ack (6 in Figure 2), proceed to Step 5 in Figure 6. Step 5 of FIG. 6 is a process in which the UE determines that an event has occurred according to the deferred area event criteria included in the LCS area event invoke message. Check the condition of the corresponding Criteria of the UE and check the report period or the valid period of the deferred service. If an event occurs, step 6 of FIG. 6 is a process of performing PS connection (Packet Switched) or CS connection (Circuit Switched) to report the event to SGSN / MSC. Step 7 of FIG. 6 determines whether a current Stopping LCS area Event has occurred from the user of the UE. If this has not happened, go to 8 of FIG. The UE sends the determined Event to the MSC / SGSN in the LCS area Event Report message. Then disconnect any open PS or CS connections.

If the Stopping LCS area Event occurs in 7 of FIG. 6, the process proceeds to step 9. The UE sends a Stopping LCS area Event to the MSC / SGSN. In addition, the Criteria for the ongoing Deferred service is deleted, and an event for the corresponding deferred service is no longer determined. Step 10 notifies the MSC / SGSN that the current deferred service has been suspended and requests the release of resources related to the deferred service. 11 is a process of disconnecting the PS or CS connection to which the UE is connected. 12 determines whether the UE should continue the deferred service anymore or not. It checks whether the criteria included in the LCS area Event Invoke message have been deleted due to the request to suspend the Deferred service of the UE or have expired because the deferred service report cyan specified in the criteria has been exceeded. If the criteria is deleted due to the request to stop the deferred service of the UE, or if the report of the deferred service specified in the criteria is exceeded, the process proceeds to step 13 to terminate the deferred service. If the criteria exists and the report cyan is valid, go back to step 5 to continue the deferred service.

7 is a format of a message of stopping deferred service that a UE sends to an MSC / SGSN. 71 is an LDR reference number (Location of Deferred Request) and 72 is an H-GMLC address (Home Gateway Mobile Location Center). 73 is an indication of stopping area event which means to stop an ongoing deferred event.

An effect of the present invention is to propose a method for stopping the deferred service according to the user's intention of the target terminal in the middle of the deferred service. The deferred service at this time is the case of multiple reports. The meaning of multiple reports is a service that reports an event to a client for a certain duration when a corresponding event (eg, change of area, periodic event, UE available event) occurs. In the prior art, before starting the multiple reports deferred service, a notification is sent to the user of the target terminal to obtain the permission of the deferred service, and when the service is granted, the deferred service proceeds for the corresponding duration. The user at the target terminal initially allowed the deferred service, but there is no way to stop the deferred service in the middle of the process.

However, since the deferred service is a service that requires the privacy protection of the user of the target terminal, the user of the target terminal should be given the authority to suspend the service for the deferred service that is conducted by multiple reports for a certain duration. The user of the target terminal should have the authority to control the notification of events related to the location of his terminal to the client. Events that occur depending on the location of the target terminal have a risk of damaging the privacy of the target terminal user.

Therefore, the present invention has proposed a method for stopping the deferred service according to the user's will of the target terminal even while the deferred service is in progress.
