摘要： A radio access network (RAN) may determine that a quality-of-service (QOS) load of a first base station exceeds a QOS load high threshold. The RAN may further determine that a set of wireless communication devices (WCDs) served by the first base station are located within a geographic area nearby a second base station. The RAN may additionally determine that the set of WCDs are responsible for at least a predefined portion of the QOS load of the first base station, and may power on the second base station. If at some point a second QOS load of the second base station falls below a QOS load low threshold, the RAN may facilitate handover of at least one of the WCDs served by the second base station from the second base station to the first base station, and may power off the second base station.

摘要： A computing device may obtain n values of a first performance indicator of a network and n values of a second performance indicator of the network. The ith value of the first performance indicator may be based on a measurement of the first performance indicator within an ith time period, and the ith value of the second performance indicator may be based on a measurement of the second performance indicator within the ith time period. A set of aggregate weighted rank values of the first and second performance indicators may be determined. A jth entry in the set of aggregate weighted rank values may be selected, and the jth value of the first performance indicator and the jth value of the second performance indicator may be used to provision the network.

摘要： A method and system for resolving handover in the presence of coverage area identifier conflict is disclosed. In a market area in which an LTE RAN and CDMA RAN operate, a base station receives a PCI that indicates a particular one of the LTE coverage areas detected by a mobile terminal. The base station determines that at least two of the LTE coverage areas have the particular PCI. Thereafter, the base station determines which one of the LTE coverage areas is the particular LTE coverage area that was indicated by the particular PCI based at least in part on a particular PN offset that indicates a particular CDMA coverage area of the CDMA RAN. The base station then arranges for handover to the particular LTE coverage area.

摘要： Systems and methods of operating multimode 3G/4G communications devices in an overlapping 3G/4G coverage area (e.g., WiMAX or LTE/CDMA-EvDO) include determining a loading condition of the 3G and 4G base stations. If the 3G and 4G base stations are lightly loaded, one or more 4G Channel Quality Indicators (CQI) are compared with one or more corresponding 3G Data Rate Control (DRC) indices to determine which of the 3G and 4G networks allows a higher data throughput. The dual mode communications device is handed off to a 4G base station associated with the 4G coverage if the 4G network allows the higher data throughput; otherwise, the dual mode communications device is handed off to a 3G base station. User priorities, application categories, and/or MIMO and diversity modes may be used to determine handoff if the base stations are more than lightly loaded.

摘要： A method and system for proactively managing a base station neighbor list. A base station or other network node tracks changes to the base station's neighbor list and identifies a recurring pattern of changes, in correspondence with a particular time of day for instance. The base station or other node then proactively changes the base station's neighbor list in anticipation of a recurrence of the identified pattern, such as in anticipation of recurrence of the time of day for instance. Advantageously, this method can help to reduce the extent to which the base station engages in an automatic neighbor relation process, and thus reduce the extent of signaling and other issues associated with engaging in that process.

摘要： A method and apparatus to help manage allocation of resources in a wireless communication system. A base station dynamically decides based on a type of bearer communication in which a user equipment device (UE) is engaged whether the base station will apply a buffer status report (BSR) process or a non-BSR process. In the BSR process, the base station responds to a scheduling request from the UE by allocating uplink resources for the UE to transmit a BSR to the base station, and the base station then receives the BSR and uses it as a basis to then allocate uplink resources for the UE to transmit bearer data to the base station. In a non-BSR process, the base station forgoes receipt and use of a BSR and instead responds to the scheduling request by allocating uplink resources for the UE to transmit bearer data to the base station.
摘要翻译：一种帮助管理无线通信系统中的资源分配的方法和装置。基站将基于用户设备设备（UE）参与的承载通信的类型来动态地决定基站是否应用缓冲状态报告（BSR）处理或非BSR处理。在BSR过程中，基站通过向UE分配用于UE发送BSR的上行链路资源来响应来自UE的调度请求，然后基站接收BSR并将其用作基础，然后分配上行链路用于UE向基站发送承载数据的资源。在非BSR过程中，基站放弃BSR的接收和使用，并且通过为UE分配上行链路资源来向基站发送承载数据来代替对调度请求的响应。
