摘要： An infrastructure assisted network transition scheme is provided. In a multi-mode wireless communication device, handover threshold data is received from a management server associated with a first wireless network comprising one or more wireless access points. The multi-mode wireless communication device receives signals from the one or more wireless access point devices of the first wireless network and generates data representing the received signals. The multi-mode wireless communication device analyzes the data representing the received signals with respect to the handover threshold data to determine when the multi-mode wireless communication device should initiate hand-in to the first wireless network and when to initiate hand-out from the first wireless network to the second wireless network. Functions are provided at the management server to enable the generation of the handover threshold data from network configuration information associated with the first wireless network.

摘要： Techniques are provided herein to improve the manageability of handover performance of multi-mode wireless client devices when roaming between a wireless local area network (WLAN) and at least one other network. Signals are received at a plurality of WLAN access points from multi-mode wireless client devices. The WLAN access points generate handover data associated with handover events of wireless Voice-Over Internet Protocol (VoIP) communication sessions for the multi-mode wireless client devices between the wireless local area network and at least one other network. The WLAN access points also generate link quality data representing status and quality of a wireless link with multi-mode wireless client devices during a VoIP communication session. A controller that is provided that is configured to receive the handover data and link quality data for multi-mode wireless client devices from the plurality of access points. The controller aggregates the handover data and link quality data for a VoIP communication session for a multi-mode wireless client device into a mobility detail record and stores the mobility detail record together with an identifier of an associated call detail record.
摘要翻译：本文提供了在无线局域网（WLAN）和至少一个其他网络之间漫游时提高多模式无线客户端设备的切换性能的可管理性的技术。在来自多模式无线客户端设备的多个WLAN接入点处接收信号。 WLAN接入点产生与无线局域网与至少一个其它网络之间的多模式无线客户端设备的无线语音互联网协议（VoIP）通信会话的切换事件相关联的切换数据。 WLAN接入点还在VoIP通信会话期间生成表示与多模式无线客户端设备的无线链路的状态和质量的链路质量数据。提供的控制器被配置为从多个接入点接收多模式无线客户端设备的切换数据和链路质量数据。控制器将用于多模式无线客户端设备的VoIP通信会话的切换数据和链路质量数据聚合成移动性细节记录，并将移动性细节记录与相关联的呼叫详细记录的标识符一起存储。

摘要： A system and method are provided in which access point (AP) devices in a wireless local area network (WLAN) are typed or configured into one of three measurement and reporting roles: Monitor-Mode AP (MMAP), Portal AP (PAP), a Border AP (BAP) or an Interior AP (IAP). APs are assigned specific link measurement requirements according to their assigned type or role. In general, MMAPs and PAPs have the greatest measurement and reporting responsibilities, BAPs have less measurement and reporting responsibilities than PAPs and IAPs have the least measurement and reporting responsibilities. The APs generate measurements that are supplied to appropriate equipment to facilitate handover decisions with respect to a dual-mode wireless client device that roams between the WLAN and another network or vice versa. As a result, link measurements are only performed by APs in locations where such measurements are necessary for handover service, thus reducing the overall processing load on the WLAN infrastructure.
