摘要： Methods and apparatus for use in provisioning mobile communication devices in wireless local area networks (WLANs) are described. A mobile communication device associates with a wireless access point of a provisioning virtual local area network (VLAN) of the network with use of a provisioning network identifier (“provisioning ESS1D”). After associating with the wireless access point of the provisioning VLAN, a primary network identifier (“primary ESSID”) associated with a primary VLAN of the network is received from the WLAN in a provisioning procedure and stored in memory of the mobile device after authentication. For subsequent communications with the WLAN, the mobile device associates with a wireless access point of the primary VLAN of the network with use of the primary network identifier.

摘要： In one illustrative example, a technique for use in operating a wireless access point (AP) for serving as a handoff indication mechanism in a first wireless network is described. The handoff indication mechanism is configured to communicate handoff indications in response to mobile devices leaving coverage of the first wireless network, via an RF coverage region of the AP, for mobile device handoff to a second wireless network. The AP is provided in an ingress or egress region of the first wireless network, where it receives RF signals from one or more communication devices and determines and sets wireless transceiver parameters for adjusting boundaries of its RF coverage region. The AP also operates with the adjusted RF coverage region to serve as part of the handoff indication mechanism in the first wireless network, so that the handoff indications are communicated in response to the mobile devices leaving coverage of the first wireless network, via the adjusted RF coverage region, for mobile device handoff to the second wireless network.

摘要： A method, mobile electronic device and system for synchronizing hand-off of a voice media session between a WAN/cellular network and a WLAN network. When a hand-off occurs, the connection with both networks is temporarily maintained and the voice data on both connections compared to determine differences in the delays experienced over both connections. The timing of one or both voice streams is adjusted to synchronize the voice streams, and then the handoff is completed.

摘要： A method and mobile device for performing wireless channel selection that employs more than one concurrent level 2 interface to facilitate a level 3 handoff. The method and device maintain an active service over a first level 3 connection through a first transceiver, establish a second level 3 connection through a second transceiver, and then switch the service over to the second connection. To establish an appropriate level 3 connection, the mobile device may evaluate candidate channels against criteria associated with the active service to ensure quality of service can be maintained over the new connection or may adapt the active service to a candidate channel.

摘要： Methods and apparatus for use in configuring a wireless access point (AP) which serves as a handoff indication mechanism (“AP tripwire”) in a wireless local area network (WLAN) for mobile device handoffs between the WLAN and a wireless wide area network (WWAN) are described. During a configuration procedure or training mode of operation of the wireless AP, radio frequency (RF) signals transmitted from a plurality of communication devices are received at the wireless AP. The plurality of communication devices include a first group of communication devices positioned at locations of undesired RF coverage of the wireless AP, outside of an RF coverage boundary of a WLAN coverage region of one or more other wireless APs of the WLAN. The plurality of communication devices also include a second group of communication devices positioned at locations of desired RF coverage of the wireless AP, around the RF coverage boundary of the WLAN coverage region and within the WWAN coverage region. Wireless transceiver parameters of the wireless AP are automatically determined and set to adjust boundaries of an RF coverage region, such that RF signal coverage of the first group of communication devices is minimized but RF signal coverage of the second group of communication devices is maximized. Preferably, the parameters of the wireless transceiver are determined through use of an adaptive beamforming technique (e.g. a minimax optimization) which is performed automatically by the wireless AP without user intervention. After the configuration procedure, the wireless AP operates with use of the configured wireless transceiver parameters in a normal, steady-state mode of operation as the AP tripwire of the WLAN.

摘要： A computer network which includes a wireless local area network; (WLAN) has at least first and second subnet segments and a router coupled between the first and the second subnet segments. The first subnet segment has a first IP subnet address range and the second subnet segment has a second IP subnet address range different, from the first IP subnet address range. At least a first wireless access point of the WLAN in the first subnet segment has both a local extended service set identifier (ESSID) and a global ESSID for mobile communication devices to associate with it. Similarly, at least a second wireless access point of the WLAN in the second subnet segment has both a local ESSID and the global ESSID for mobile communication devices to associate with it. The global ESSID is used for accessing a global virtual local area network (VLAN) which spans the entire network including the first and the second subnet segments. Initially, a mobile communication device associates with the first wireless access point using the local ESSID. Just prior to the establishment of a Voice over IP (VoIP) session, however, the mobile device reassociates with the first wireless access point using the global ESSID of the global VLAN. Thus, the VoIP session is established and maintained for the mobile device in the global VLAN. If a handoff to the second wireless access point in the second subnet segment is made during the VoIP session, the mobile device associates with the second wireless access point using the global ESSID of the global VLAN. After termination of the VoIP session, the mobile device associates with a wireless access point of the WLAN using the local ESSID Advantageously, no IP address reassignment for inter-subnet handoffs are needed during VoIP sessions, which improves the timeliness and reliability of such handoffs.
摘要翻译：一种包括无线局域网的计算机网络; （WLAN）具有至少第一和第二子网段以及耦合在第一和第二子网段之间的路由器。第一个子网段具有第一个IP子网地址范围，第二个子网段具有与第一个IP子网地址范围不同的第二个IP子网地址范围。至少第一子网段中的WLAN的第一无线接入点具有用于移动通信设备与其相关联的本地扩展服务集标识符（ESSID）和全局ESSID。类似地，第二子网段中的WLAN的至少第二无线接入点具有本地ESSID和用于移动通信设备与其相关联的全局ESSID。全局ESSID用于访问跨越整个网络的全局虚拟局域网（VLAN），包括第一个和第二个子网段。最初，移动通信设备使用本地ESSID与第一无线接入点相关联。然而，在建立IP语音（VoIP）会话之前，移动设备将使用全局VLAN的全局ESSID与第一个无线接入点重新关联。因此，为全球VLAN中的移动设备建立和维护VoIP会话。如果在VoIP会话期间切换到第二子网段中的第二无线接入点，则移动设备使用全局VLAN的全局ESSID与第二无线接入点相关联。在VoIP会话终止之后，移动设备使用本地ESSID与WLAN的无线接入点相关联。有利的是，在VoIP会话期间不需要用于子网间切换的IP地址重新分配，这提高了这种切换的及时性和可靠性。
