Resource management granularity, determine currently judge the position UE whether change based on location parameter, then further according to the location parameter,
Whether current location and the last position synchronous with network side for comparing this UE are identical, current to determine the need for reporting
Location information.
Here, the last position synchronous with network side of UE record, the i.e. position of the UE of network side current record,
Therefore, whether identical by comparing the current location of UE and the position, it can judge the position for the UE that network side is recorded
When whether having been subjected to, in this way, illustrating that the position UE of network side record is correctly, not need to update, accordingly if identical
Ground, also there is no need to report the position of UE.
It is same come the current location and the last and network side that compare this UE preferably, can specifically use following methods
