Abstract: A user equipment performs downlink measurement on neighbour cells, but the measurement performance on a target cell (in terms of measurement period/sampling/accuracy etc) is dependent on the relative performance difference between the target cell and a reference cell. The reference cell may be the serving cell, or may be the strongest cell. The network is thus able to keep track of the required number of target cells without degrading the measurement performance of important cells. The UE on the other hand is still able to save its battery as much as possible while making full use of DRX.

Abstract translation: 用户设备对相邻小区进行下行链路测量，但是目标小区（在测量周期/采样/精度等方面）的测量性能取决于目标小区与参考小区之间的相对性能差异。 参考单元可以是服务小区，或者可以是最强小区。 因此，网络能够跟踪所需数量的目标小区而不降低重要小区的测量性能。 另一方面，UE在充分利用DRX的同时仍能够尽可能地节省电池。

Abstract: The present invention relates to methods and devices for mobility management in a cellular communications system. A user equipment maintains (21) at least two sets of mobility trigger parameters. Each set of mobility trigger parameters corresponds to a predetermined user equipment speed range. The user equipment determines (22) a speed range that the speed of the user equipment falls into and selects (23), based on the determined speed range, at least one set of mobility trigger parameters to be used for performing mobility-based decisions. If the user equipment is in connected mode a network base station may select a set of mobility trigger parameters to be used for performing handover decisions based on a determined speed range of the user equipment. Advantages are that ping-pong mobility decisions may be avoided and it is sufficient to determine a range for the UE speed, which is less complicated than determining an accurate speed of the UE particularly in idle mode.
