Abstract: Measurement handling is of interest in a user equipment (UE) in connected mode, with the UE being configured with multiple downlink component carriers (CCs). The UE evaluates the signal quality of a specific CC of the configured CCs against a configurable threshold to determine the need for neighbor cell measurements. The UE performs neighbor cell measurements if the signal quality of the specific CC is below the configurable threshold. In this way, robust and efficient measurement handling is provided, even though the UE is configured with multiple component carriers.

Abstract translation: 测量处理在连接模式下对用户设备（UE）感兴趣，UE配置有多个下行链路分量载波（CC）。 UE根据可配置的阈值评估配置的CC的特定CC的信号质量，以确定对相邻小区测量的需要。 如果特定CC的信号质量低于可配置阈值，则UE执行相邻小区测量。 以这种方式，即使UE配置有多个分量载波，也提供了鲁棒且高效的测量处理。

Abstract: A method of decreasing radio link failure in challenging mobility scenarios for a user equipment (UE), device working in a cellular telecommunication network with a base station of each cell is disclosed. The method comprises measuring signal conditions for serving cell and neighboring cells periodically; and estimating channel variations and comparing the estimate with a threshold value such that, when channel variations are determined to exceed a channel variations threshold, performing an accelerated procedure comprising predicting whether handover is likely to occur in connection with the next scheduled measurement instant based on the signal measurements such that when handover is predicted, the procedure directly proceeds with sending an initial measurement report transmission request. Thereby handover delay can be reduced such that risk of radio link failure is reduced at significantly varying signal conditions. A UE device and a computer program are also disclosed.

Abstract: 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.

Abstract: Embodiments herein relate to a method in a second network node (13,14) for detecting a short stay handover of a user equipment (11) in a second cell (16) in a telecommunication system (10). The user equipment (11) is handed over from a first cell (15) to the second cell (16) and from the second cell (16) to a third cell (17) in the telecommunication system (10). The second network node sends, to a first network node (12,18), an indication in a message that a short stay handover has occurred when determined that the user equipment (11) is handed over to the third cell (17) before a time threshold, thereby enabling the first network node (12,18) to detect the short stay handover.

Abstract: 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

Abstract: The present invention relates to methods and devices for mobility management UE 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.

Abstract translation: 本发明涉及蜂窝通信系统中移动性管理UE的方法和设备。 用户设备维护（21）至少两组移动性触发参数。 每组移动性触发参数对应于预定的用户设备速度范围。 用户设备基于所确定的速度范围确定（22）用户设备的速度落入并选择（23）的速度范围，用于执行基于移动性的决定的至少一组移动性触发参数。 如果用户设备处于连接模式，则网络基站可以基于用户设备的确定的速度范围来选择要用于执行切换决定的一组移动性触发参数。 优点是可以避免乒乓移动性决定，并且确定UE速度的范围是足够的，这比确定UE的准确速度，特别是在空闲模式下更为复杂。
