MOBILITY STATE ENHANCEMENTS

摘要

In a cellular communications network, a measurement report is requested to enable handover conditions to be established. In one approach, a measurement report is based on satisfaction of an event. Signalling for this measurement report includes one or more parameters on the basis of which the event is defined, including a trigger time defining a time period over which the event should be satisfied for the report to be triggered. In one approach, speed dependent scaling is applied to a parameter other than the trigger time, in the defined event. In another approach, a handover scenario, concerning the nature of the cell in which the user equipment is operational, and optionally that of a neighbouring cell, governs the definition of a trigger event.

1. A wireless communications apparatus configured to operate in a cellular communications network, the apparatus comprising a measurement unit operable to perform a measurement on performance of said apparatus in said cellular network, trigger event defining means operable to define a trigger event on the basis of at least one measurement and at least two parameters, one of said parameters being a trigger event time parameter being an indication of a time period over which a trigger event must be satisfied, another of said parameters being a configuration parameter for configuring the trigger event, a measurement controller operable to determine, on the basis of said measurement, if said trigger event has been satisfied over the trigger time period and, in the event that said trigger event has been satisfied over the time period, to emit a measurement report comprising performance information for a cell in which the apparatus is operational in use, wherein the configuration parameter is scalable dependent on speed of said apparatus.
