摘要： A method and apparatus for reducing handover interruptions when a mobile device executes handover including a random access procedure is described herein. When handover is desirable, a time offset associated with a random access opportunity is determined. The time offset relates the timing of the next random access opportunity to the frame timing of a target access point. Based on the time offset, a network element, e.g., the mobile device, a serving access point, or a mobility management entity, determines a handover start time. Handover is executed at the determined start time to generally align the beginning of the handover execution with the beginning of the next random access opportunity, and therefore, to reduce handover interruption.
摘要翻译：这里描述了当移动设备执行包括随机接入过程的切换时减少切换中断的方法和装置。当需要切换时，确定与随机访问机会相关联的时间偏移。时间偏移将下一个随机访问机会的定时与目标接入点的帧定时相关联。基于时间偏移，诸如移动设备的网络元件，服务接入点或移动性管理实体确定切换开始时间。在确定的开始时间执行切换，以将切换执行的开始与下一个随机访问机会的开始对齐，并且因此减少切换中断。

摘要： A technique for handling radio link failure in a communication network (10) is provided. A method implementation of this technique comprises the steps of maintaining radio link failure information including the identifier of a user equipment (UE) effected by the radio link failure together with at least one of a time stamp of when the radio link failure was detected and a reference to a cell (C1) which was serving the user equipment (UE) before the radio link failure was detected, receiving reconnection information including an identifier of a reconnected user equipment (UE) effected by a radio link failure after the user equipment (UE) is reconnected to the communication network and correlating the radio link failure information with the reconnection information to obtain a correlation result.

摘要： In at least one embodiment taught herein, the point in a packet transmission sequence space at which hyper frame numbers are incremented is changed at least temporarily as part of handover processing, where a mobile station (12) is handed over from a source cell to a target cell. More particularly, in at least one embodiment, changing the triggering point, e.g., changing the transmission sequence number at which HFNs are incremented, is done in a manner that delays a next incrementing of the HFN for a radio bearer that was handed over, therefore giving additional time for the mobile station (12) and the handover target base station (16) to ensure synchronization in the face of possible packet losses in the source and/or target cells arising during the handover event.

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： An object of the present invention is to provide a mechanism for handling a handover in a more efficient way. The invention relates to a method in a mobility controller (180) in a radio access network for preparing a handover. The method comprises the following steps to be taken during data transmission between a mobile terminal (140) and a source base station (120), before the handover: Sending a request to a candidate base station (122), which request aims at measuring and reporting timing alignment to be used by the mobile terminal (140) when communicating with the destination base station (122) after the handover, if the candidate base station becomes the destination base station (122) after the handover; receiving a report from the destination base station (122) comprising said requested timing alignment; and when the destination base station (122) is selected among the at least one candidate base stations, sending a message to the mobile terminal (140) to use said timing alignment received from the destination base station (122) when communicating with the destination base station (122) after the handover.
