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

摘要： A user equipment UE context is stored in a local memory including a session context for a breakout data session. 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 address and addressed to the source IP address, and uses 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 session context that need not change when the UE moves from one LBGW to another. Embodiments are detailed for routing through more than two LBGWs, and for when the UE initiates another breakout data session on the new LBGW ion addition to the aforesaid breakout data session.
摘要翻译：用户设备UE上下文存储在本地存储器中，包括用于突发数据会话的会话上下文。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，并发送到源IP地址，并使用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LBGW移动到另一个LBGW时，会话上下文的全局路由IP地址不需要改变。详细描述了通过两个以上LBGW进行路由的实施例，以及当UE向上述突围数据会话添加新的LBGW离子时启动另一个突发数据会话。

摘要： 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.
摘要翻译：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。

摘要： A system and method is directed to updating information in a mobile network. A dynamic signaling routing protocol is extended over bi-directional tunneling between a mobile router and its home agent such that information associated with the home agent of the mobile router reflects roaming of the mobile router as it travels from its home network. The information is determined as a function of a characteristic associated with each link of the tunnel between the mobile router and its home agent. In one embodiment, the information includes a cost metric associated with the cost of the tunnel. The information is advertised to another router. The other router employs the information associated with the tunnel to determine a path for communication.
