摘要： Establishing voice calls in an IP based VPN includes determining the relative location of a terminating point with respect to an originating point of a new communication containing the voice data, determining one or more IP addresses to egress the communication from the originating point to the terminating point, creating a VPN identifier in the new communication, passing the new communication to the terminating point and removing the VPN identifier from the new communication. The VPN identifier can be an extra field added to an encapsulation coding scheme of the voice data.

摘要： In a floor control system for a network, a floor control server controls a floor-based application for communications between multiple participant terminals. The server carries out a floor determination process that includes an adaptive waiting function. Upon receiving an initial floor request message, the server waits for additional requests before determining the floor winner. The wait time is a function of the floor request load. When the system is lightly loaded, the wait time is generally small. For heavier request loads, the wait time is generally longer, to ensure that a reasonable number of requests are received before awarding the floor. The wait time may be limited by a maximum wait time, which is a function of the floor request load. If a designated number of floor requests is received before the maximum wait time expires, a temporary floor winner is granted the floor if its priority is sufficiently high.
摘要翻译：在用于网络的楼层控制系统中，楼层控制服务器控制用于多个参与者终端之间的通信的基于楼层的应用。服务器执行包括自适应等待功能的楼层确定过程。在接收到初始楼层请求消息之后，服务器在确定楼层赢家之前等待附加请求。等待时间是楼层请求负载的函数。当系统轻载时，等待时间通常较小。对于较重的请求负载，等待时间通常较长，以确保在授予发言权之前收到合理数量的请求。等待时间可能受限于最大等待时间，这是楼层请求负载的函数。如果在最大等待时间到期之前接收到指定数量的楼层请求，则如果其优先级足够高，则临时楼层优胜者被授予楼层。

摘要： A method and system for group call control in a broadband wireless network. A group call (push-to-talk) server initiates and regulates group call communication sessions. A wireless base station communicates with one or more group call participants. When a request to participate in a group call is received, it is examined to see if it contains a group call ID or other group call indicator. If not, regular call resources are allocated, if available. If so, it is determined whether another group member is attached to the base station. Group call resources are then reserved, if available, based on this determination. The resources allocated for the group call may also depend on whether the system supports multicast on the downlink to group members, or whether losing audio is supported. In some embodiments, network resources may be reallocated to support the group call.

摘要： Embodiments of the present invention are directed to providing a method and system for call admission control and preemption of multiple bit-rate applications in a digital communication system. Multiple bit-rate applications such as streaming video can specify a Quality of Service (QoS) profile having multiple levels. When there are insufficient resources in the network to support an incoming multiple bit-rate call, the system determines whether, by reducing the bit-rate of the incoming call or by preemption of lower priority components of existing calls, enough resources can be recovered to support the incoming call.

摘要： A capability for determining a media distribution tree for use in distributing content to a plurality of user devices is provided. Using the distributed content distribution capability, one or more of the user devices to which the content is to be distributed functions as a relay point that performs content replication and distribution functions for one or more other user devices. The content is distributed using a media distribution tree into which the user devices are arranged. A method for determining a media distribution tree for use in distributing content to a plurality of user devices includes grouping the user devices into a plurality of regions, determining, for each of the regions, a regional tree to be formed by the user devices grouped into the region, and connecting the regional trees to determine thereby the media distribution tree. By utilizing user devices as relay points within the media distribution tree, usage of network resources, such as ports at media servers, is significantly reduced.

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： 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： An exemplary embodiment of a method is implemented in a wireless network and is advantageous in that an undesired interim media channel link which would have been used in prior art systems is identified during call setup and avoided. In response to a call request in the wireless network for a call with a first user's wireless subscriber unit, a determination is made if one of a calling home node and a called home node of the first user's wireless subscriber unit should not be used as a node in the media channel such as due to the one node's remote location relative to the rest of the nodes in the media channel. A resulting media channel is established so that the one of the calling home node and the called home node is not part of a path of the media channel thereby minimizing the total distance and delay of the media path.
