Problems solved by technology
However, in order to improve the quality of service of the mobile network, network optimization is frequently carried out in various places, so it is necessary to notify the positioning platform of the cell data that has undergone network optimization in a very timely manner, otherwise the CELLID data in the database will be different from the actual Inconsistencies in the data, resulting in positioning errors or positioning failures when users use positioning services

Embodiment 4
[0066] In Embodiment 4 or Embodiment 5, the location unit of the service access location needs to record all the CELLIDs that have been queried and the latest query record time of the CELLID. Therefore, when the location unit of the service access location receives a CELLID data from the current network, It is necessary to search all the recorded CELLIDs, and then determine whether the CELLID has been queried and whether the current time and the latest query record time are in the same clearing interval or within, and then decide whether to send the CELLID data to the attribution location unit. This embodiment has reduced the storage load of the CELLID in the service access place due to the addition of an automatically updated query record table compared to embodiment four and embodiment five; The searched CELLID, so as long as it is judged that there is a CELLID record in the query record table during the search, it can be concluded that there is no need to re-query. Compared...

The invention relates to a method for optimizing district identification number data, which comprises that when a request for inquiring a data base is received, inquiring a district identification number data, judging whether effective district identification number data are existed, if the data are existed, and then ending, if not, renewing district identification number data in the district identification number data base. the invention also relates to a system for optimizing district identification number data, which comprises a service platform, a positioning platform which is connected with the service platform, the positioning platform comprises at least an ownership positioning unit which is provided with a district identification number data base, and an inquiry module which is connected with the district identification number data base. The invention timely checks the completeness of CELLID data in an inquiry data base before a user uses a positioning service or during the user is utilizing the positioning service, and adds or renews for the data base, thereby overcoming error locating or failure locating which is caused by non-timely data synchronization which is caused by frequent optimization of networks.
Description
technical field [0001] The invention relates to a data optimization method and system, in particular to a data optimization method and system for cell ID (CELLID) positioning in a mobile communication network. Background technique [0002] At present, most of the positioning technologies in the mobile cellular network are based on CELLID, that is, the positioning platform first obtains the cell identification number of the cell where the mobile terminal is currently located, and then queries the database to obtain the latitude and longitude information corresponding to the CELLID, so that the approximate location of the mobile terminal can be known, and then Through the calculation of other auxiliary data (such as time advance, signal arrival time or GPS satellite data, etc.), the position of the mobile terminal with high accuracy is obtained. [0003] Whether the positioning method described above is successful or not depends on the correctness and completeness of the cell ...
