摘要： A system for originating connectivity fault management (CFM) frames on non-CFM aware switches is disclosed. In the disclosed system, an OAM (Operations Administration and Management) proxy networking device connected to a core Ethernet network operates with one or more CPE (Customer Premises Equipment) devices to which it is communicably connected to support CFM out to the CPE devices without requiring that the CPE devices themselves implement CFM functionality. The OAM proxy networking device generates Connectivity Check (CC) frames, Loopback reply frames, and Linktrace reply frames for MEPs (Maintenance End Points) or MIPs (Maintenance Intermediate Points) contained in communication ports on the CPEs. These CFM frames generated by the OAM proxy networking device are then sent within messages from the OAM proxy networking device to the appropriate CPE. When the CPE device receives a message from the OAM proxy networking device containing one of these CFM frames, it checks the operability of a communication port indicated by the message. If the port is operable, the CPE device extracts the CFM frame from the message and originates it through the OAM proxy networking device into the core Ethernet network. The OAM proxy networking device further operates to process Connectivity Check frames received from the core Ethernet network and addressed to the CPE devices by maintaining an MEP connectivity database. As a result, these received Connectivity Check frames are dropped without forwarding to the CPE devices.

摘要： The present invention relates generally to a cellular telecommunications network. Each cell has at least one base station for sending messages on a downlink of a Frequency Division Duplex (FDD) to end user equipments within the cell and for receiving messages on an uplink from end user equipments within the cell. Other end user equipment located within the cell which have no or only poor communication directly with the base station over the FDD communicate with the base station indirectly via an intermediate end user equipment, such as a mobile telephone. The intermediate end user equipment includes an FDD transceiver and a Time Division Duplex (TDD) transceiver and an FDD/TDD interface. The intermediate end user equipment receives signals from the base station over the FDD using the FDD transceiver and relays them via the FDD/TDD interface and the TDD transceiver towards a relevant one of the other end user equipments over a TDD and receives signals from the other end user equipment over the TDD using the TDD transceiver and relays them via the FDD/TDD interface and the FDD transceiver to the base station over the FDD, The network provider thereby improves capacity and coverage by utilizing TDD channels without having to deploy and TDD infrastructure.

摘要： Neighbor cell hearability can be improved by including an additional reference signal that can be detected at a low sensitivity and a low signal-to-noise ratio, by introducing non-unity frequency reuse for the signals used for a time difference of arrival (TDOA) measurement, e.g., orthogonality of signals transmitted from the serving cell sites and the various neighbor cell sites. The new reference signal, called the TDOA-RS, is proposed to improve the hearability of neighbor cells in a cellular network that deploys 3GPP EU-TRAN (LTE) system, and the TDOA-RS can be transmitted in any resource blocks (RB) for POSCH and/or MBSFN subframe, regardless of whether the latter is on a carrier supporting both PMCH and POSCH or not. Besides the additional TDOA-RS reference signal, an additional synchronization signal (TDOA-sync) may also be included to improve the hearability of neighbor cells.

摘要： The present invention allows transmission of multiple signals between masthead electronics and base housing electronics in a base station environment. At least some of the received signals from the multiple antennas are translated to being centered about different center frequencies, such that the translated signals may be combined into a composite signal including each of the received signals. The composite signal is then sent over a single feeder cable to base housing electronics, wherein the received signals are separated and processed by transceiver circuitry. Prior to being provided to the transceiver circuitry, those signals that were translated from being centered about one frequency to another may be retranslated to being centered about the original center frequency.

摘要： A packet-based multimedia service is provided to a terminal in a network. A packet signaling connection is established between the terminal and the network. Signaling information for the multimedia service is transferred via the packet signaling connection using Session Initiation Protocol (SIP) or a similar protocol. A circuit bearer connection is also established with the terminal. Data for the multimedia service is transferred via the circuit bearer connection. This allows the data to be carried across networks which do not support the required QoS functionality for the packet-based service, or which cannot efficiently carry packet-based data. The circuit bearer connection can be established by a network entity or by the terminal. The circuit bearer can be interworked to a packet-switched bearer at some point in the network, such as at a gateway, so as to provide a remote party with the appearance that a fully packet-switched connection is being used.

摘要： The performance of a voice conference using a packet-based conference bridge can be improved with a number of modifications. In one modification, the conference bridge receives speech indication signals from the individual packet-based terminals within the voice conference, these speech indication signals then being used by the conference bridge to select the talkers within the voice conference. This removes the need for speech detection techniques within the conference bridge, hence decreasing the required processing power and the latency within the conference bridge. In another modification, the conference bridge sends addressing control signals to the individual packet-based terminals selected as talkers, these addressing control signals directing the terminals selected as talkers to directly transmit their voice data packets to the other terminals within the voice conference. This direct transmission of voice data packets can reduce transcoding and latency within the network. These two modifications could further be combined, resulting in a conference bridge that receives speech indication signals, selects the talkers for the voice conference and outputs addressing control signal to the talkers. In this case, the advantages of the two modifications are gained as well as additional capacity advantages resulting from no voice signals actually traversing the conference bridge.
摘要翻译：使用基于分组的会议桥的语音会议的性能可以通过多种修改来改进。在一个修改中，会议桥接收来自语音会议内的各个基于分组的终端的语音指示信号，然后由会议桥使用这些语音指示信号来选择语音会议内的讲话者。这消除了在会议桥内对语音检测技术的需要，从而减少会议桥内所需的处理能力和延迟。在另一个修改中，会议桥将寻址控制信号发送到被选为讲话者的各个基于分组的终端，这些寻址控制信号指示被选择为讲话人的终端直接将语音数据分组发送到语音会议内的其他终端。语音数据分组的这种直接传输可以减少网络内的转码和延迟。这两个修改可以进一步组合，从而产生一个接收语音指示信号的会议桥，选择用于语音会议的讲话者，并向讲话人输出寻址控制信号。在这种情况下，获得了两个修改的优点以及由语音信号实际上穿过会议桥而产生的附加容量优点。

摘要： A method and system are provided having an uplink control structure and a pilot signal having minimal signal overhead for providing channel estimation and data demodulation in a wireless communication network. The uplink control structures enable mobile terminals to communicate with corresponding base stations to perform various functions including obtaining initial system access, submitting a bandwidth request, triggering a continuation of negotiated service, or providing a proposed allocation re-configuration header. A dedicated random access channel is provided to communicatively couple the base station and the mobile terminal so that the mobile terminal can select a random access signaling identification. A resource request is received at the base station to uplink resource information from the mobile terminal and an initial access information request is received from the mobile terminal to configure the base station connection. Pilot signals with varying density configurations are provided to include low density symbol patterns for multiple contiguous resource blocks and high density symbol patterns for single resource blocks.

摘要： Virtual routers that abstract photonic sub-domains are provided for GMPLS networks. A virtual router uses a link viability matrix to keep track of the set of viable connections between inputs and outputs of a photonic sub-domain. A virtual router may receive RSVP-TE signaling messages and either allocate a working input to output link pair or, if explicitly signaled, verify that the requested link is currently viable. A virtual router also advertises, in its link state updates, the current set of possible outputs for any input link. Shortest path computations can be implemented utilizing virtual routers by modifying a topology graph in accordance with the link viability matrix of the virtual router.

摘要： A set of critical nodes or links is identified on the network through which most of the shortest paths on the network occur. Each node compares their distance to end points on the network with a distance between the end points and each of the distinct critical nodes. Where the distance between the end points and the critical nodes is shorter than the distance between the end points and the node, the node is not on the shortest path and does not install forwarding state. Where the distance between the end points and the critical node is larger than or equal to the distance between the end points and the node, the node may be on the shortest path between the pair of end nodes and installs forwarding state. Installation of forwarding state may cause packet duplication, but determining forwarding state is dramatically simplified. The level of duplication may be reduced by selecting a larger number of critical nodes on the network.
