ABSTRACT:
Disclosed is a method of processing a periodic location request when a location service system receives the periodic location request sent by a location service (LCS) client in relation to target user equipment and confirms the periodic location request as a periodic location request. The location service system allocates a reference number for the periodic location request based on a predefined rule. After locating the target user equipment, location service system returns a location result of the target user equipment, which carries the reference number, to the LCS client. According to the reference numbers allocated by the location service system, the LCS client can associate a location result of the target user equipment returned by the location service system with the periodic location request initiated by this LCS client, so as to guarantee processing normality of the periodic location request. In addition, with the reference number, the LCS client can explicitly identify which periodic location request should be cancelled when the LCS client initiates a cancellation procedure.
