Reporting mobility State of UE in RRC (Radio Resource Control) establish, re-establish or reconfigure signalling.

摘要

A UE reports its mobility state in RRC signalling. In one embodiment, the mobility state is selected from normal, medium or high or can report the number of cell changes the UE has performed within a predetermined period. The network configures the UE in dependence on the reported mobility state, such as setting a parameter for measuring or reporting neighbour cells, for example: suspend a serving cell quality threshold as a condition of measuring/reporting; limit inter-frequency and/or inter-radio access technology reporting; set a shortest measurement reporting gap; disable an event trigger; and/or set layer 3 filtering of measurement results for faster reporting.
