摘要： Mobility parameters, such as those used in handoff decisions, are based on the speed of User Equipment (UE) (10), measured at two points. UE speed estimates are taken at both the UE (10) and base station (12), and the two speeds compared. If the speeds match (or differ by less than a predetermined amount), one or more mobility parameters are adapted based on the UE speed. These parameters may include time to trigger (TTT), time to satisfy (TTS), measurement time, forgetting factor, β, measurement period (Tm), handover prohibit timer, MeasurementReportingmargin, HOmargin, hysteresis, and the like. The UE speed comparison may be performed at the UE (10) or at the base station (12). In one embodiment, a plurality of UE speed ranges are defined (e.g., low, medium, high), with corresponding mobility parameter values associated with each range.
摘要翻译：移动性参数，如用于切换决策的参数，是基于在两点测量的用户设备（UE）（10）的速度。在UE（10）和基站（12）两者都进行UE速度估计，并且比较两个速度。如果速度匹配（或差别小于预定量），则基于UE速度来适配一个或多个移动性参数。这些参数可以包括触发时间（TTT），满足时间（TTS），测量时间，遗忘因子，测量周期（Tm），切换禁止定时器，测量报告率，停留时间，滞后等。 UE速度比较可以在UE（10）处或在基站（12）处执行。在一个实施例中，多个UE速度范围被定义（例如，低，中等，高），具有与每个范围相关联的对应的移动性参数值。

摘要： The present invention relates to a method and an arrangement (102, 104, 106, 202, 302, 304, 502, 504, 702, 704, 1000, 1014) for prioritizing one of multiple cell-related mobility decisions associated with multiple parallel mobility events being triggered, comprising recognizing parameter settings associated with at least two parallel mobility events being triggered (steps 406, 604; 806), evaluating the parameter settings for determining which cell-related mobility decision to prioritize (steps 408; 606; 808), and performing a task according to the cell-related prioritized mobility decision (steps 410, 608; 814), to achieve a cell re-selection in idle mode or a hand over in connected mode. By applying multiple parameter settings a better performance is achieved as can be seen by a reduced percentage of time a User Equipment (102, 202, 302, 502, 702, 1000) is not connected to the best cell.

摘要： The teachings presented herein enable a user terminal to perform a fast recovery from a radio link failure. In one aspect, the improvement in recovery time is achieved by commanding or otherwise causing the user terminal to perform radio link failure (RLF) recovery at a cell that is known to possess the user context, while considering that this cell should yield good radio conditions (if not the best) to the user terminal. A cell may be predefined for use by the user terminal in recovering its radio connection. Based on providing signal strength thresholds to the user terminal, for use in determining whether to use a predefined cell for reconnecting to the network, the user terminal attempts RLF recovery first in the predefined cell. By providing user context to the predefined cell in advance of a recovery attempt by the user terminal, the time for recovery is lessened. Note that the user terminal also may infer which cells are preferred.

摘要： 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.
