摘要： Various embodiments provide a method and apparatus of providing a non-overlapping ring-mesh network topology which reduces costs (e.g., the number of network links) while providing resiliency to failure and meeting QoS requirements (e.g., network delay attributed to traversing the network architecture). In particular, a set of target nodes belonging to a cluster are connected through N rings. Each node is member of all N rings and no link between nodes in a ring is duplicated in another ring.

摘要： Embodiments of the present invention are directed to providing a method and system for call admission control for a Long Term Evolution (LTE) network shared between a plurality of user classes, such as, for example, a public safety user class and a consumer user class. An admission control module oversees the call admission process based on a specified policy profile. When there are insufficient resources in the network to support an incoming call, the admission control module will consult with a preemption module to determine whether, by preemption of lower priority calls, enough resources can be recovered to support the incoming call.
摘要翻译：本发明的实施例涉及提供一种用于在多个用户类（例如公共安全用户类和消费者用户类）之间共享的长期演进（LTE）网络的呼叫准入控制的方法和系统。准入控制模块根据指定的策略配置文件来监督呼叫准入进程。当网络资源不足以支持来电时，准入控制模块将咨询抢占模块，以确定通过优先级较低的呼叫是否可以恢复足够的资源来支持来电。

摘要： A capability is provided for decomposing a P2P network into a plurality of sub-networks and, further, for using the decomposed P2P network. A P2P network is decomposed to form a plurality of sub-networks, where each of the sub-networks is a P2P network. A P2P network may be decomposed into sub-networks based on one or more decomposition criteria (e.g., geographic location, community of interest, and the like, as well as various combinations thereof). The decomposition of the P2P network is encoded in a network map. A node may use the network map to join the decomposed P2P network. A node may join one, some, or all of the sub-networks. The sub-networks of a decomposed P2P network may be arranged in any suitable number of hierarchical levels.

摘要： In one embodiment, an automatically maintained, distributed source tree (DST) network has a plurality of fully connected internal nodes. One or more internal nodes may be connected to one or more external nodes. A first internal node synchronizes its link-state database with another internal node by sending and receiving respective Reduced Sequence Number Packet-Data-Units (PDUs) (RSNPs). An RSNP includes summary information for link-state packets (LSPs) (1) originated by the first internal node, (2) received by the first internal node from the other internal node, and (3) received from and/or originated by external nodes. If an internal link fails, then the corresponding end-nodes may recover and maintain automatic DST operation by entering either relay-mode or switch-mode operation. In relay-mode operation, an end-node tunnels packets to the other end-node via an intermediary node. In switch-mode operation, an intermediary node is selected to forward packets from one end-node to the other end-node.
摘要翻译：在一个实施例中，自动维护的分布式源树（DST）网络具有多个完全连接的内部节点。一个或多个内部节点可以连接到一个或多个外部节点。第一内部节点通过发送和接收相应的减少序列号分组数据单元（PDU）（RSNP）来将其链路状态数据库与另一内部节点同步。 RSNP包括由第一内部节点发起的链路状态分组（LSP）（1），（2）由第一内部节点从另一个内部节点接收的摘要信息，以及（3）从外部接收和/或发起的节点。如果内部链路发生故障，则相应的终端节点可以通过进入中继模式或切换模式操作来恢复和维护自动DST操作。在中继模式操作中，终端节点经由中间节点将分组隧道传送到另一终端节点。在交换模式操作中，选择中间节点将分组从一个终端节点转发到另一个终端节点。

摘要： In one embodiment, a method for processing, at an enhanced Session Initiation Protocol (SIP) proxy (e-proxy), (1) a SIP INVITE message to a first user at an IPv4/IPv6 dual-stack (DS) host, connected to an IPv6 network, from a second user at an IPv4 host, connected to an IPv4 network. The e-proxy receives the SIP INVITE message from the IPv4 network. When the e-proxy determines that Dual Stack Transition Mechanism (DSTM) service is required, the e-proxy obtains a temporary IPv4 address for the DS host, finds a suitable tunnel end-point (TEP), and sends a corresponding, but modified, INVITE message to the DS host. The modified INVITE message body includes invocation of DSTM service, the temporary IPv4 address, the TEP's IPv6 address, and the IPv4 host's IPv4 address. The e-proxy sends a BIND message to the TEP to bind the DS host's IPv6 address to the temporary IPv4 address for proper tunneling.

摘要： A method and apparatus are provided for a set of procedures that a push-to-talk (PTT) server can use to control multiple simultaneous media streams within a talk group. The present invention provides floor control messages and protocols for identifying, transmitting, and distributing the simultaneous media streams. The invention may be used with any real-time protocol (RTP) payload format as long as the encoding allows a receiver of the packets means to distinguish between the transmitting clients. Although the present invention provides server-based control of multiple transmissions, end-point-based transmission control procedures are supported.

摘要： A telecommunication network establishes a telephone call from a first location that generates compressed voice packets to a second location. The telecommunication network includes a plurality of switches, a first interworking function ("IWF") coupled to the first location and coupled to a first switch of the plurality of switches, a second IWF coupled to the second location and coupled to a second switch of the plurality of switches, and a network database coupled to said first switch. When a telephone call is initiated from the first location, the first switch receives signaling information from the first location. The first switch then queries the network database based on the signaling information and determines whether the second location uses compressed voice packets based on the query. Finally, the first switch establishes a connection between the first IWF and the second IWF if it is determined that the second location uses compressed voice packets. The connection bypasses the plurality of switches, and therefore reduces tandeming in the network.

摘要： A capability is provided for supporting a service location capability in a peer-to-peer network (P2P), such as a Chord network or other P2P network. In one embodiment, a method for locating a service within a P2P network is provided. The P2P network includes a plurality of nodes, including a target node which performs the method for locating the service within the P2P network. The target node includes a search table including a plurality of entries identifying a respective plurality of nodes of the P2P network. The method includes detecting a request to search for the service within the P2P network and initiating, toward at least one of the nodes of the search table, a service search request. The service search request is a request to identify at least one node of the P2P network that supports the service. The service search request includes information indicative of the service and a search range for use by the node receiving the service search request.
