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： The present invention relates to methods and arrangements for handling unreliable scheduling grants in a WCDMA-communication system. A user equipment detects that a received scheduling grant is unreliable and adjust its serving grant based on that information. The user equipment is also able to report continuously received unreliable grants as an event to the network, allowing the network to adapt its operation to reduce the unreliable grants.

摘要： A method of initiating handover in a cellular radio system with CDMA access technology. A mobile station (5) is present in a serving cell (4) and handover should be made from a serving cell (4) to a target cell (7). Before the handover is made the signal quality from the target cell (7) is estimated. The mobile measures the signal quality, preferably Ec/Io of the pilot tone, from the serving cell. An RNC node calculates the estimated signal quality as a function of the measured signal quality, a load dependent quantity at the serving and target cells and decides to initiate the handover when the estimated signal quality at the target cell is better than a predefined minimum value or is better than the measured signal quality. As load dependent quantity the total output transmission powers Ps and Pt may used.

摘要： The present invention relates to a handover process in a cellular telecommunication system. In cellular systems were the communication resources are shared among a plurality of mobile terminals, there is no designated transmission resources maintained in a source cell when a mobile station makes a handover attempt. If the handover fails, the mobile terminal reverts back to the source cell in a random access procedure. The random access is contention based. There is a severe risk of dropped call due to the one or more random access contentions are lost. The present invention solves the problem by designating a source cell specific preamble to the mobile terminal in the handover command. In case the handover fails the mobile terminal accesses the source cell by transmitting the designated preamble on the RACH. The source cell identifies the dedicated preamble as relating to the specific mobile terminal and gives it priority to transmission resources. The access procedure is further shortened because the identification of the mobile terminal need not be verified before the data communication can be started.
摘要翻译：本发明涉及蜂窝电信系统中的切换过程。在蜂窝系统中，通信资源在多个移动终端之间共享，当移动台进行切换尝试时，在源小区中没有维护指定的传输资源。如果切换失败，则移动终端以随机接入过程返回到源小区。随机访问是基于争用的。由于一个或多个随机访问争用丢失，导致呼叫中断的严重风险。本发明通过在切换命令中指定移动终端的源小区特定前导码来解决该问题。在切换失败的情况下，移动终端通过在RACH上发送指定的前同步码来访问源小区。源小区将专用前导码标识为与特定移动终端相关，并且将其优先于传输资源。进一步缩短访问过程，因为在数据通信可以开始之前不需要验证移动终端的识别。

摘要： The invention is directed towards determining whether a hard handover should be performed of a mobile station (48) in relation to a first group of cells (16, 18, 20, 24) including a number of active cells (16, 18, 20) and handled by a first cell handling device (10) to a second group of cells (32, 36, 38) handled by a second cell handling device (26), when the cell handling devices lack a direct communication link (Iur). Either the first cell handling device or the mobile station obtains measurements of link quality between the mobile station and cells of the groups, determines a first and second total quality factor for the groups, performs an evaluation of a preferred group involving comparing the first total quality factor with the second quality factor and initiates a handover from the first group to the second group if the second group is preferred.

摘要： A method in a first base station (105) for handling a data transferral in a cellular network (100) is provided. The first base station (105) serves a user equipment (125) via a first cell (115). When the first base station (105) obtains an indication that a second cell (120) provides a coverage for the user equipment (125), the first base station (105) sends a message to a second base station (110) serving the second cell (120). The message commands the second base station (110) to prepare for receiving the uplink data from the user equipment (125) via the second cell (120). The first base station (105) also sends a request to the user equipment (125). The request commands the user equipment (125) to prepare for sending the uplink data both via the first cell (115) and via the second cell (120) in respective separate intra frequency transmissions.

摘要： The invention provides a method and a network node for controlling configuration of measurements to be performed by a user equipment (150a, 150b) operating in a wireless communication system (101). A configured measurement corresponds to at least one reporting criteria and the user equipment (150a, 150b) is able to support a limited number of parallel reporting criteria. Measurements to be performed by the user equipment in parallel may be requested by different network nodes such as a positioning server (140) and an eNodeB (110a, 110b). By letting a network node, such as the positioning server (140) or the (eNodeB 110a, 110b), obtain information on measurements requested by another network node the network node is able to configure the user equipment with a set of measurements that does not exceed at least one predetermined threshold for parallel reporting criteria

摘要： User equipment (40) is to be handed over from a source cell (15) to a target cell (25/35) in a radio communication network. The user equipment (40) is assigned dedicated uplink resources in the source cell (15), and a handover candidate cell (25/35) is prepared for receiving the user equipment by obtaining information about the assigned dedicated uplink resources in the source cell. A radio base station (20/30) for the handover candidate cell (25/35) is listening for user equipment transmissions and determines, when receiving a user equipment transmission, whether the received user equipment transmission can be detected based on information about the assigned dedicated uplink resources in the source cell in order to assess if the received user equipment transmission is coming from user equipment for which the handover candidate cell has been prepared. The radio base station (20/30) for the handover candidate cell (25/35) initiates a handover procedure for the user equipment (40) if it is assessed that the received user equipment transmission is coming from user equipment for which the handover candidate cell has been prepared. In this way, handover can be initiated and completed even if the serving radio base station (10) of the source cell (15) can not receive a handover-triggering measurement report from the UE (40).

摘要： A basic idea is to introduce an additional paging schedule for user equipment in connected mode that differs from the paging schedule used for user equipment in idle mode. Consequently, the inventive mechanism relies on distributing (S1) a notification of an upcoming change of system information in paging messages according to a first paging schedule for user equipment in idle mode, and distributing (S2) a notification of an upcoming change of system information in paging messages according to a second paging schedule for user equipment in connected mode. The second paging schedule for user equipment in connected mode is different from the first paging schedule for user equipment in idle mode. In this way, a satisfactory load distribution is achieved, at the same time as UEs in both connected and idle mode are able to receive important system information notifications.
摘要翻译：一个基本思想是为连接模式下的用户设备引入附加的寻呼时间表，而不同于用于空闲模式的用户设备的寻呼时间表。因此，本发明的机构依赖于根据用于空闲模式的用户设备的第一寻呼调度，在寻呼消息中分发（S1）系统信息即将到来的更改的通知，并且分发（S2）即将到来的系统信息改变的通知在寻呼消息中根据用于连接模式的用户设备的第二寻呼时间表。连接方式的用户设备的第二个寻呼调度与空闲模式下的用户设备的第一个寻呼调度不同。以这种方式，实现令人满意的负载分配，同时连接和空闲模式中的UE能够接收重要的系统信息通知。
