Abstract

The invention provides an optimization method of a location service during a relocation process, which is used for a wireless communication system comprising CN, SRNC, DRNC, SAS or SMLC and a mobile terminal. The method comprises: step 1. SRNC receiving a request message of CN periodic location, and selecting an SAS centric mode for location, and triggering SAS or SMLC to perform the position locating process of the request of the current periodic location; step 2. when the relocation from SRNC to DRNC is performed, SRNC sending the information relative to the position locating process of the current periodic location request to DRNC, while the relative information containing the relevant information of SAS or the relevant information of SMLC; step 3. DRNC receiving and storing the information relative to the position locating process of the current periodic location request, and establishing new communication process together with SAS or SMLC according to the relevant information of SAS or the relevant information of SMLC, and receiving the information of the current locating result that is measured and reported for the SAS or SMLC cycle, and transmiting the information of the current location result to CN so as to rationalize and simplify the position locating flow during the relocation process.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and system for optimizing processing of location services in a relocation process. Background technique [0002] Mobile positioning services in wireless network systems are receiving more and more attention. The main applications of mobile positioning services include: emergency call positioning services for user safety; positioning tracking applications; personal positioning services (such as traffic, accommodation and other service industry information inquiries); intelligent transportation positioning; wireless network system design and Resource management; billing for wireless network systems (determining the communication cost of certain locations according to the call rate), etc. [0003] In the existing location service positioning process, if the access network side detects that the relocation of the Serving Radio Network Controller (SRNC, Serving Radio Net...
