摘要： An access-point node to a first network cell of a radio access network, to an access-center node and to a radio access network enable local service providers in rural areas to provide mobile telecommunication at low cost for end users. The access-point node of the invention is configured to establish, maintain, and release a local user-data radio channel, which consists of a first local channel section having as endpoints a first terminal device located in the network cell and the access-point node, and of a second local channel section having as endpoints the access-point node and a second terminal device located in the network cell. The access-point node is configured to exchange packetized user data and control data with an assigned superordinate access-center node for establishing, maintaining and releasing communication between the first terminal device and a third terminal device located outside the network cell. Link cost between the radio access network and the core network may be strongly reduced.

摘要： A method for establishing a secure communications tunnel between a first node and a second node in a communication system includes a plurality of networks each having a respective tunnel control entity for controlling establishment of secure communications tunnels in the respective network. The first node operates in a first one of the networks and the second node operates in a second one of the networks. The method includes determining a route for the communications tunnel from the first network to the second network by way of one or more of the other networks. A request message digitally signed by the first node is formed and the identities of the tunnel control entity of the first network and the tunnel control entities of the other networks are included. The request message from the first node to the tunnel control entity of the second network is transmitted. In response to that message, the secure communication tunnel is established between the first node and the second node by way of the tunnel control entities identified in that message.

摘要： The invention provides a method and system for a network which includes a plurality of nodes, preferably routers, a shared network segment for communication between the nodes, and several multicast channels in the shared network segment on which the nodes, preferably routers, can send multicast messages to the other nodes. A specific multicast channel is provided on which the nodes can send specific start multicast messages to other nodes, wherein a node which starts a protocol application, preferably a routing protocol application such as Open Shortest Path First (OSPF) protocol, is adapted to send a multicast start message on the specific multicast channel. Another node, preferably a router, receiving this start message is adapted to validate the authenticity of the start message and to send a response message.

摘要： A method and system for adding and monitoring a server to an existing server pool are disclosed. A joining server registers with a server within the server pool. The joining server is authenticated by a server within the server pool. When the joining server receives the list of all active servers within the server pool, the joining server computes a new identification for itself, assigns that identification to itself, and then determines a caretaker server to monitor the joining server. Once the registration is successful, the newly joined server can communicate within the server pool and keep current of all events and changing conditions of the server pool.

摘要： A method and system for transferring contexts from a previous access router (PR) to a new access router (NR) that is subsequently associated with a Mobile Node (MN). For example, transferred contexts may include, but are not limited to, Security, Quality of Service (QOS), Header Compression, and Buffers. A context is transferred from the PR to the NR. Any change in an element of the context is conveyed by the NR to the MN in a secure fashion, even though a Security Association does not yet exist between the NR and MN. The NR provides an authenticated security context update to the MN, e.g., advising when the type of encryption has changed from Triple Data Encryption Standard (DES) to DES. The NR utilizes the Security Association between the PR and the MN, to provide such an authenticated security context update to the MN over a RAN or a wireless LAN.
摘要翻译：一种用于将上下文从先前的接入路由器（PR）传送到随后与移动节点（MN）相关联的新的接入路由器（NR）的方法和系统。例如，传送的上下文可以包括但不限于安全性，服务质量（QOS），报头压缩和缓冲区。上下文从公关转移到NR。即使安全关联在NR和MN之间还不存在，NR的任何变化都以安全的方式由NR传送给MN。 NR提供对MN的认证安全上下文更新，例如，当加密类型从三重数据加密标准（DES）改变为DES时提供建议。 NR利用PR和MN之间的安全关联，通过RAN或无线LAN向MN提供这种经认证的安全上下文更新。

摘要： Data services may be enhanced by mitigating the need for unplanned core network capacity expansion or network element upgrades and reconfiguration, by offloading data to an alternative network, such as Exchange Point (IXP) or other operator network. A method can include monitoring a status of a transit network. The method can also include offloading traffic to the transit network from a transport network when a predetermined condition is met. The predetermined condition includes the status of the transit network indicating that the transit network is operational.

摘要： A method performed at an apparatus includes receiving a request for media content corresponding to a user equipment; requesting and receiving some of the media content from a server; and if the requested media content should not be optimized, sending, through the network toward the user equipment, information that causes a node to direct additional requests from the user equipment for the media content through the network toward the server without passing through the apparatus. Another method includes receiving a redirect message comprising an indication corresponding to a location of media content and comprising a tag indicating the redirect message should cause a first apparatus to redirect requests from a user equipment for the media content to a server having the media content without passing through a second apparatus; and for requests received from the user equipment and corresponding to the indication, forwarding requests through the network toward the server.
