Abstract: A method for upgrading an access controller that controls and coordinates a plurality of radio nodes (RNs) each associated with a cell in a cluster of cells belonging to a radio access network includes initializing a new access controller. The new access controller is to replace a current access controller currently controlling and coordinating the plurality of RNs cell in the cluster. A most lightly loaded one of the plurality of RNs is identified. All UEs currently attached to the identified RN is caused to be handed off to a neighboring cell in the cluster. After all the UEs have been handed-off from the identified RN, the identified RN is rebooted so that it is being controlled and coordinated by the new access controller. The steps of causing the UEs to be handed-off and rebooting the identified RN are repeated for a second one of the plurality of RNs.

Abstract: Systems and methods are provided for resolving Primary Scrambling Code (PSC) ambiguity. A radio link having the same PSC as that reported by user equipment (UE) may be created on some or all internal cells which are chosen based on radio frequency (RF) proximity to a serving cell of the UE or one or more iterations of a PSC resolution set selection process. If the UE is reporting the PSC of one of these cells, the UE and a Node Bs will be able to successfully complete a synchronization procedure to add one of the radio links to the UE's active set, while any remaining created radio links can be deleted. After a certain number of successful radio link additions, the combination of the PSC and active set may be considered to be resolved, therefore, negating a need to resolve the PSC in subsequent soft handover requests.

Abstract translation: 一种用于升级控制和协调与属于无线电接入网络的小区中的小区相关联的多个无线电节点（RN）的接入控制器的方法包括初始化新的接入控制器。 新的接入控制器是替换当前控制和协调集群中的多个RN小区的当前接入控制器。 识别出多个RN中最轻的一个。 导致当前连接到所识别的RN的所有UE被切换到群集中的相邻小区。 在已经从所识别的RN切换所有UE之后，重新启动所识别的RN，使得它被新的接入控制器控制和协调。 对于多个RN中的第二个，重复使UE切换并重新启动所识别的RN的步骤。

Abstract translation: 提供了系统和方法来解决主要扰码（PSC）模糊。 可以在基于与UE的服务小区的射频（RF）接近度或者一个或多个迭代的一个或多个迭代中选择的一些或所有内部小区上创建与用户设备（UE）报告的具有相同PSC的无线电链路 PSC分辨率集选择过程。 如果UE正在报告这些小区之一的PSC，则UE和节点B将能够成功地完成同步过程，以将无线链路中的一个添加到UE的活动集，而任何剩余的创建的无线电链路可被删除 。 在一定数量的成功的无线电链路添加之后，可以认为PSC和活动集合的组合被解决，因此，否定在随后的软切换请求中解析PSC的需要。
