    Abstract: A method and apparatus for triggering procedures to handover an ongoing communication session between a mobile station (MS) and a correspondent node (CoN) from via a first network of a first type to via a second network of a different type. Communication session continuity is maintained by transferring communication session context information when a handover is imminent from a network component in a first network path to a network component in a second network path, and by forwarding downlink and uplink signals via the network components in both the first and second network paths until the ongoing communication session can be established via the second network path. The context information includes the session communication parameters, such that the second network path can allocate resources and establish routing between the MS and the CoN.

    Abstract: A mesh network including at least one channel master (CM) and a plurality of mesh points (MPs). The CM sends a channel change intention message to at least one of the MPs indicating the CM's intention to change from a first channel to a second channel. Upon reception of the channel change intention message, the at least one MP determines whether to switch from the first channel to the second channel. The at least one MP sends a channel change response message to the CM. The CM then determines whether to change from the first channel to the second channel based on the channel change response message. The channel change intention message may indicate a change of mode, a change of bandwidth or a change of a number of channels. The channel change intention message may indicate the timing of the channel change.

    Abstract: Several methods are provided for communicating emergency call capability information between a station and an access point (AP) in a wireless local area network. The methods include advertising by the AP of its emergency call capabilities and announcing by the station of its emergency call capabilities. The AP can advertise its emergency call capabilities in a beacon frame, a probe response frame, a reassociation response frame, or a reauthentication response frame. The station can announce its emergency call capabilities in an association request frame, a reassociation request frame, an authentication request frame, or a reauthentication request frame.

    Abstract: A method and system for autonomous channel coordination for a wireless distribution system (WDS) are disclosed. A wireless communication system includes a plurality of access points (APs) and the APs communicate each other via a WDS. A coordinated channel group (CCG) of a plurality of member APs is established. The member APs of the CCG camp on a WDS channel used for the WDS among the member APs of the CCG. One AP among the member APs of the CCG is designated as a master AP. The master AP coordinates with other member APs of the CCG for selecting and configuring the WDS channel for the CCG and addition and deletion of member APs. By allowing APs to define a CCG, changes of the WDS channel are performed autonomously while maintaining connectivity.

    Abstract: A method for handover a mobile unit (UE) from a first base station (BS1) to a second base station (BS2) in a wireless communication systems employing smart antenna technology. Following trigger events of a handover, the mobile station generates a physical signal sounding pulse transmitted by an isotropic antenna. The sounding pulse may consist of a common sequence of symbols or a specific sequence of symbols that uniquely identifies the mobile station. A series of sounding pulses can be sent according to a power ramping procedure until a base station has focused a communications beam toward the mobile. Receiving base stations provide feedback information upon detection of the sounding pulse allowing the mobile unit (UE) and/or base station (BS1-BS4) to form communication beams toward each other. A mapping protocol may also be utilized by the communication system.

    Abstract translation: 一种在采用智能天线技术的无线通信系统中将移动单元（UE）从第一基站（BS1）切换到第二基站（BS2）的方法。 在切换的触发事件之后，移动站产生由各向同性天线发送的物理信号探测脉冲。 探测脉冲可以由符号的公共序列或唯一地标识移动站的特定符号序列组成。 可以根据功率斜坡过程发送一系列探测脉冲，直到基站将通信波束聚焦到移动台为止。 接收基站在检测到探测脉冲时提供反馈信息，允许移动单元（UE）和/或基站（BS1-BS4）彼此形成通信波束。 通信系统也可以使用映射协议。
