摘要： A wireless communication system constructed according to the present invention assigns mobile units to equalize loading among a plurality of mobile switching centers. The wireless communication system includes the plurality of mobile switching centers and a base station system which includes a plurality of base station controllers, each of which couples to a plurality of base stations. A plurality of mobile units served by the system are assigned to the mobile switching centers so that loading is equalized. In one particular construction of the wireless communication system, a dispatching switch couples the base station system to the plurality of mobile switching centers and performs the assignments of the mobile units. In an example of operation, upon attachment of a mobile unit, the dispatching switch determines loading of each of the mobile switching centers. Then, based upon the loading, the dispatching switch assigns the mobile unit to one of the mobile switching centers, the "serving" mobile switching center. During subsequent calls, the dispatching switch establishes a transparent path between a base station controller servicing the call and the serving mobile switching center. Thus, once the serving mobile switching center is determined, operation is transparent to the serving base station controller and the serving mobile switching center. In another particular construction, each of the base station controllers couple to each of the mobile switching centers via a network. In such case, each of the base station controllers and each of the mobile switching centers includes additional equipment which performs at least a portion of the operations of the dispatching switch. The network may be dissimilar to a conventional data structure supported by the wireless communication system.
摘要翻译：根据本发明构造的无线通信系统分配移动单元以均衡多个移动交换中心之间的负载。无线通信系统包括多个移动交换中心和包括多个基站控制器的基站系统，每个基站控制器耦合到多个基站。由系统服务的多个移动单元被分配给移动交换中心，使得负载相等。在无线通信系统的一个特定结构中，调度交换机将基站系统耦合到多个移动交换中心并执行移动单元的分配。在操作的示例中，在附接移动单元时，调度开关确定每个移动交换中心的负载。然后，基于负载，调度交换机将移动单元分配给移动交换中心之一，即“服务”移动交换中心。在后续呼叫期间，调度交换机在服务于呼叫的基站控制器与服务移动交换中心之间建立透明路径。因此，一旦确定了服务移动交换中心，则对服务基站控制器和服务移动交换中心的操作是透明的。在另一特定结构中，每个基站控制器经由网络耦合到每个移动交换中心。在这种情况下，每个基站控制器和每个移动交换中心都包括执行调度交换机的至少一部分操作的附加设备。该网络可能与由无线通信系统支持的常规数据结构不同。

摘要： A wireless communication system constructed according to the present invention assigns each serviced mobile unit to a serving mobile switching center to minimize mobility management overhead and to equalize loading among a plurality of mobile switching centers. The wireless communication system includes the plurality of mobile switching centers and a base station system which includes a plurality of base station controllers, each of which couples to a plurality of base stations. A plurality of mobile units served by the system are assigned to the mobile switching centers so that loading is equalized. In one particular construction of the wireless communication system, a dispatching switch couples the base station system to the plurality of mobile switching centers and performs the assignments of the mobile units. In an example of operation, upon attachment of a mobile unit, the dispatching switch determines loading of each of the mobile switching centers. Then, based upon the loading, the dispatching switch assigns the mobile unit to one of the mobile switching centers, the "serving" mobile switching center. During subsequent calls, the dispatching switch establishes a transparent path between a base station controller servicing the call and the serving mobile switching center. Thus, once the serving mobile switching center is determined, operation is transparent to the serving base station controller and the serving mobile switching center. In another particular construction, each of the base station controllers couple to each of the mobile switching centers via a network. In such case, each of the base station controllers and each of the mobile switching centers includes additional equipment which performs at least a portion of the operations of the dispatching switch. The network may be dissimilar to a conventional data structure supported by the wireless communication system. In still another implementation, a signaling message router function routes signaling messages to the serving mobile switching center by using the mobile unit's temporary identification number (as assigned by the serving mobile switching center). The signaling message router function may be implemented in the network coupling the base station sub-system with the mobile switching center (in a message router), in the base station controller or in the mobile switching center.

摘要： The present invention is a system for optimizing an existing wireless network and additions to an existing network. The system determines a value representing estimation of traffic in discrete bins within a geographic area. The traffic estimation includes a distribution of handover and new cell traffic based at least in part on the presence of a road in any bin or the proximity of a bin to a handover boundary. The cell coverage and carrier allocations of existing cells are adjusted in view of the traffic estimation.
