Abstract

Disclosed is an interactive method for reporting location reports by a target UE in an LCS. The method comprises: the target UE receiving a location request initiated by an applicant and reporting a location report to the LCS system after detecting the occurrence of an event triggering a location report; the LCS system returning to the target UE a location report acknowledgement after receiving the location report submitted by the target UE. Further, while submitting the location report to the LCS system, the target UE starting a timer designating a time period and judging whether it has received a location report acknowledgement returned by the LCS system within the designated time period, if yes, stopping the timer designating the time period; otherwise, reporting once again the location report to the LCS system and re-starting the timer designating the time period at the same time. In accordance with this method, errors in reporting location reports are reduced and the uncertainty in implementation of LCS is lowered.

Claims

1. An interactive method for reporting location reports by a target user equipment (UE) in a location service (LCS), the method comprising:

A. the target UE receiving a location request initiated by an applicant, and reporting a location report to the LCS system after having detected the occurrence of an event triggering a location report;

B. after receiving the location report reported by the target UE, the LCS system returning to the target UE a location report acknowledgement.

2. The interactive method for reporting location reports by a target UE in an LCS according to claim 1, wherein said step A further comprises:

at the same time of reporting a location report to the LCS system, the target UE starting a timer designating a time period, and waiting for the LCS system to return a location report acknowledgement.

3. The interactive method for reporting location reports by a target UE in an LCS according to claim 2, further comprising:

the target UE judging whether it has received the location report acknowledgement returned by the LCS system within the designated time period, if it has received the acknowledgement, stopping the timer designating the time period;

otherwise, reporting to the LCS system the location report once again, restarting the timer designating the time period at the same time, and waiting for the LCS system to return a location report acknowledgement.

4. The interactive method for reporting location reports by a target UE in an LCS according to claim 3, further comprising:

setting in advance a valid time period for re-reporting caused by not receiving a location report acknowledgement, wherein said valid time period includes a determined number of designated time periods, and when the target UE has not received the location report acknowledgement returned by the LCS system within said valid time period, the target UE will no longer report the location report to the LCS system in the current interactive process between the target UE and the LCS system.

5. The interactive method for reporting location reports by a target UE in an LCS according to claim 3, further comprising:

setting in advance the number of re-reportings caused by not receiving a location report acknowledgement, wherein if the target UE has not received the location report acknowledgement returned by the LCS system after the number of re-reportings of the location report to the LCS system by the target UE exceeds the set number, the target UE will no longer report the location report to the LCS system in the current interactive process between the target UE and the LCS system.

6. The interactive method for reporting location reports by a target UE in an LCS according to claim 4, after the target UE no longer reports the location report to the LCS system, the method further comprising:

a. the target UE setting a flag indicating that sending of the location report is unsuccessful, and when the target UE updates its location and enters an area covered by another CN, sending once again the location report to the current CN covering the target UE according to the saved flag of unsuccessful sending of the location report.

7. The interactive method for reporting location reports by a target UE in an LCS according to claim 6, after step a, the method further comprising:

after receiving the location report acknowledgement returned by CN, the target UE clearing the saved flag of unsuccessful sending of location report.

8. The interactive method for reporting location reports by a target UE in an LCS according to claim 5, after the target UE no longer reports the location report to the LCS system, the method further comprising:

a. the target UE setting a flag indicating that sending of the location report is unsuccessful, and when the target UE updates its location and enters an area covered by another CN, sending once again the location report to the current CN covering the target UE according to the saved flag of unsuccessful sending of the location report.

9. The interactive method for reporting location reports by a target UE in an LCS according to claim 8, after step a, the method further comprising:

after receiving the location report acknowledgement returned by CN, the target UE clearing the saved flag of unsuccessful sending of location report.

10. The interactive method for reporting location reports by a target UE in an LCS according to claim 1, wherein said location report acknowledgement carries parameters.

11. The interactive method for reporting location reports by a target UE in an LCS according to claim 10, wherein said parameters comprise the information of the processing result of the location report.
