    Abstract: In a push-to-talk communication system, frames are sent by a talking device before confirmation that the device has the floor. These are flagged, sent for a limited duration and buffered in a listening device. Playback is triggered either by receipt of frames flagged as ‘confirmed’ or by receipt of the ‘receiving talk burst’ message from a server.

    Abstract translation: 在即按即说的通信系统中，在确认设备之前，由通话设备发送帧。 这些被标记，发送有限的时间并缓冲在听音设备中。 通过接收标记为“确认”的帧或通过从服务器接收到“接收到通话突发”消息来触发播放。

    Abstract: A communications multi-service network arrangement for transporting information packets from a user station to a destination comprises a label switched core network constituted by a plurality of abstract nodes interconnected by tunnels. Each abstract node comprises one or more real nodes. An access network provides user access to the core network. A route across the core network comprises a plurality of label switched path sections specified in terms of a sequence of abstract nodes, the route being identified by a label stack identifying a quality of service capable connection from the end station via the access network to the core network and across the core network to a destination.

    Abstract: In a label switch communications network, a third level of label is employed in conjunction with a dynamic multiplex constraint-based routed label switched path (CR-LSP) in order to achieve implicit switching at nodes within the network. Implicit switching occurs when a switching function takes place at a node without the need for any control function being required at that node. A three-layer label stack provided at the edge of the network achieves end-to-end connection oriented behaviour with guaranteed Quality of Service. The use of the three-layer label stack concentrates the control of the network to the two edges of the network and a single central switching stage of the network.

    Abstract translation: 在标签交换机通信网络中，与基于动态多路复用约束的路由标签交换路径（CR-LSP）结合使用第三级标签，以便在网络内的节点处实现隐式切换。 当在节点处进行切换功能而不需要在该节点处需要任何控制功能时，就会发生隐式切换。 提供在网络边缘的三层标签堆栈可以实现端到端的面向连接的行为，保证服务质量。 使用三层标签堆栈将网络的控制集中在网络的两个边缘和网络的单个中央交换阶段。

    Abstract: On receipt of a request for a communication session over a communications network, such as an Internet Protocol communications network, a path for the session is established. In a preferred example the communications network is an MPLS network and the method uses a modified version of the SIP messaging protocol. Bandwidth along a chosen path is reserved and a messaging protocol such as CR-LDP used to establish this reserved path for the communication session. Internet protocol and MPLS communications networks typically only support uni-directional flows. Several methods for establishing bi-directional communication sessions over internet protocol communications networks that use MPLS connections are described. This is particularly useful for telephony applications using internet protocol communications networks. In a preferred example, the established connection provides a guaranteed level of quality of service.

    Abstract: A telecommunications system comprises an asynchronous transfer mode (ATM) network having uncommitted bandwidth, and a plurality of adaptive grooming routers (AGR) coupled to the network. The AGRs comprise a group adapted to function as a virtual transit exchange whose fabric and control are distributed over the group. The visual comprising the AGRs incorporates independent connection control and call routing functions and has means for determining the current system status whereby to set up narrow band connections across the ATM network based on that status determination.

    Abstract: On receipt of a request for a communication session over a communications network, such as an Internet Protocol communications network, a path for the session is established. In a preferred example the communications network is an MPLS network and the method uses a modified version of the SIP messaging protocol. Bandwidth along a chosen path is reserved and a messaging protocol such as CR-LDP used to establish this reserved path for the communication session. This creates a delay in the time taken to establish a communication session because the process of choosing a path and reserving bandwidth must be completed before the CR-LDP protocol is used. This delay is reduced by using modified SIP Protocol to perform the CR-LDP function too.
