    • An in-line skateboard for supporting a rider with his feet in side-by-side relation one on each side of the longitudinal centerline of the board has a toe abutment wall for preventing forward movement of the rider's shoes and a heel support supporting the shoe heels at an elevation substantially above the surface of the board. The wheel base is very short, preferably no greater than the distance between the toe abutment and the heel support, to provide steering control by the rider by leaning the skateboard and shifting his weight to provide more or less weight on the front or rear wheels, respectively. The in-line wheels may be replaced with a single skate blade for using the skateboard on ice.

    • Embodiments of the invention disclose a system and a method for determining a rank of a node in a multi-hop wireless network, wherein the network includes a gateway node, client nodes, and relay nodes, wherein a node p(i) is a default parent of the node i having a rank, and the network uses a directed acyclic graph (DAG) topology. The method comprises steps of transmitting at least one data packet from the node to the default parent node over a wireless link; counting a number of successful transmissions of most recent transmissions of data packets; determining an expected transmission time (ETX) for the wireless link based on the number of successful transmissions in the most recent transmissions; and assigning a rank R(i) to the node based on the rank of the parent node and the ETX.

    • A Method and apparatus for a user handing over to a home NodeB are provided. The method comprises the following steps: when the user initiates a handover procedure from a source NodeB to a target home NodeB, a target home NodeB gateway receiving a relocation request message from a mobility management unit of a core network; the target home NodeB gateway generating a user context for the user according to the relocation request message, allocating a user context identifier for the user context, and sending the user context identifier and the relocation request message to the target home NodeB; and when receiving a relocation request acknowledgement message replied by the target home NodeB, the target home NodeB gateway sending the relocation request acknowledgement message to the mobility management unit of the core network. The application of the above technical solution can ensure the handover of a user to a home NodeB which serves as a target NodeB successfully.
    • 提供了一种用于将用户切换到家庭节点B的方法和装置。 该方法包括以下步骤:当用户从源节点B发起到目标本地节点B的切换过程时,目标本地NodeB网关从核心网的移动性管理单元接收重定位请求消息; 所述目标家庭NodeB网关根据所述重定位请求消息为所述用户生成用户上下文,为所述用户上下文分配用户上下文标识符,并将所述用户上下文标识符和所述重定位请求消息发送到所述目标家庭基站; 并且当接收到由目标家庭基站B回复的重定位请求确认消息时,目标本地NodeB网关向核心网络的移动性管理单元发送重定位请求确认消息。 上述技术方案的应用可以确保用户成功切换到用作目标节点B的家庭基站B。
