    • An architecture by which combined scheduling and network coding can be used in mesh networks, and more particularly wireless mesh networks. In various embodiments, this architecture includes a scheduling MAC protocol for scheduling nodes in the mesh network in order to take advantage of network coding opportunities. The schedule takes advantage of these opportunities by assigning a gain to transmit packets based upon the number of packets that are transmitted concurrently and choosing a schedule which minimizes the gain over the scheduling horizon. Regarding the assigned gain, in one embodiment this value is one for basic non-encoded operations and two or more for encoded operations. A scheduling MAC protocol is also used to announce and arbitrate network coding opportunities by indicating which packets (as characterized by their transmission slot) are to be encoded with each other.
    • 可以在网状网络中使用组合调度和网络编码的架构,更具体地说,是无线网状网络。 在各种实施例中,该架构包括用于调度网状网络中的节点的调度MAC协议,以便利用网络编码机会。 该调度通过分配增益来利用这些机会,基于同时发送的分组的数量并选择最小化调度范围上的增益的调度来传送分组。 关于分配的增益,在一个实施例中,该值是用于基本非编码操作的值,对于编码操作,该值是两个或更多个。 调度MAC协议还用于通过指示哪些分组(由其传输时隙表征)将被彼此编码来通告和仲裁网络编码机会。

    • A user equipment UE context is stored in a local memory of a former local breakout gateway, the UE context comprising a session context for a breakout data session. The UE changes attachment from the former local breakout gateway to the new local breakout gateway due to movement. The UE is asigned the source internet protocol address. The session context comprises a source internet protocol IP address, a destination IP address, an identifier of a former local breakout gateway LBGW and an identifier of a new LBGW. The former LBGW receives first traffic originating from the destination IP adderess and addressed to the source IP address, and user the session context to forward the first traffic from the former LBGW to the new LBGW via a first tunnel. There is thus a globally routable IP address for the sesion context that need not change when the UE moves form one LGBW to another. Embodiments are detailed fo routing throught more than two LBGWs, and for when the UE initiates another breakout data session on the new LBGW in addition to the aforesaid breakout data session.
    • 用户设备UE上下文存储在前一本地突围网关的本地存储器中,该UE上下文包括用于突发数据会话的会话上下文。 由于移动,UE将从前的本地突围网关的附件改变到新的本地突围网关。 UE被称为源互联网协议地址。 会话上下文包括源互联网协议IP地址,目的地IP地址,前一个本地突围网关LBGW的标识符和新的LBGW的标识符。 前者LBGW接收来自目的地IP地址的第一个流量,并发送给源IP地址,并且用户会话上下文通过第一个隧道将前一个LBGW的第一个流量转发到新的LBGW。 因此,当UE从一个LGBW移动到另一个时,就不需要改变,因此,用于sesion上下文的全局可路由的IP地址。 实施例详细描述了通过多于两个LBGW的路由,以及当UE在除了上述突围数据会话之外还在新的LBGW上启动另一个突发数据会话时。

    • A heterogeneous wireless communication network includes a home access network 210 with a home network characteristic and a home network policy, and a visiting access network 232 with a visiting network characteristic and a visiting network policy. A packet data node gateway 124, 228 is adapted to communicate with the home access network 210 and the visiting access network 232 over a first communication path 216. An out-of-band communication path 230 substantially separate from the first communication path 216 is adapted to carry the visiting network policy from the visiting access network 232 to the packet data node gateway 124. When the terminal is handed off from the home network to the visiting network, the packet data node gateway 124 retrieves the visiting network policy, and the terminal accesses the visiting network over the first communication path 216 using the visiting network policy.

    • A voicemail module is described (as example given would be a predefined prompt 42), which module is intended to be incorporated into a voicemail system of one or more end users (for example the companies greeting prompt for all employees). The voicemail module includes a plurality of settings, some of which may be provided by the developer and some of which may be provided by the end user. One of the settings might be corporate a new greeting or the SMS number (47) or the email address (49) to which a notification may be sent when a message has been recorded. For at least some of the settings that are provided by the developer, a flag or some other mechanism is provided for indicating whether the developer allows the end user to modify the setting. Thus, a flexible voicemail module is provided that enables the developer of the module to retain control of the aspects of the module that can be configured by the end user.
