摘要： A radio access network includes a transport network layer; a radio network layer having a layer 2 network for communicating between entities within the radio network layer by exchanging datagrams having a predetermined format used only within the radio network layer. Accordingly, the present invention provides for a true decoupling at layer 2 between the radio network layer and the transport network layer.Addressing at layer 2 can enable both connectionless and connection oriented using an overlay connectivity model. Layer 2 in the radio network layer is implemented as an Ethernet network.

摘要： In some embodiments of the present invention there is provided a frame structure for transmitting an integer number of OFDM symbols in which some of the OFDM symbols are to be transmitted in a unicast format and some of the OFDM symbols are to be transmitted in a broadcast format. The frame structure includes partitioning of a frame into at least two portions to accommodate both unicast and broadcast modes in the frame. The frame structure is used for transmitting multiple frames in a serial manner from at least one transmitter. The unicast mode supports transmission of OFDM symbols from a single transmitter to a single receiver. The broadcast mode supports transmission of OFDM symbols from multiple transmitters to all receivers within range of the multiple transmitters. The multicast mode supports transmission of OFDM symbols from multiple transmitters to multiple receivers within range of the multiple transmitters.

摘要： In a coherent optical receiver of an optical communications network, a method of recovering a clock signal from a high speed optical signal received through an optical link. A set of compensation vectors are adaptively computed for compensating Inter-symbol Interference (ISI) due to at least polarization impairments of the optical signal. A channel delay is estimated based on the computed compensation vectors. The estimated channel delay is subtracted from the computed compensation vectors to generate corresponding modified compensation vectors. Finally, the modified compensation vectors are used to derive a recovered clock signal.

摘要： Bit-transparent muxing of an input signal for transport through an optical communications network is provided. A fixed length container of the optical communications network is defined, which includes an overhead and a payload. A stuffing ratio (α) is based on a line rate of the input signal and a data rate of the container. A number (NFS) of fixed stuffs is computed based on the stuffing ratio (α). The input signal and NFS fixed stuffs are inserted into the payload of the container, and the computed number NFS stored in the container's overhead.

摘要： A method and system for maintaining quality of service parameters for transmissions as a native Ethernet service between a first network having a first communication protocol and a second network having a second communication protocol that is different from the first communication protocol. The interworking device includes a first network interface operable to communicate with the first communication network using the first communication protocol, a second network interface operable to communicate with the second communication network using second communication protocol and a processing unit in communication with the first network interface and the second network interface. The processing unit receives a frame from the first network in the first communication protocol, maps parameters corresponding to quality of service parameters in the first communication protocol to quality of service parameters in the second communication protocol and assembles a data packet in the second communication protocol. The assembled data packet includes mapped quality of service parameters.

摘要： An apparatus and a method of optimizing voice quality on a network having end-points that are voice over Internet Protocol (IP) devices. Default parameters of the end-points are initialized. Network performance parameters are measured and evaluated to determine whether they signify that connection to the network is below a desired level of operation. If so, the default parameters of the end-points are re-set based on the evaluation. The adjustment may entail re-negotiating the CODEC connection and re-setting parameters for packet size and resetting parameters for jitter buffer size.

摘要： An adaptable orthogonal frequency-division multiplexing system (OFDM) that uses a multiple input multiple output (MIMO) to having OFDM signals transmitted either in accordance with time diversity to reducing signal fading or in accordance with spatial diversity to increase the data rate. Sub-carriers are classified for spatial diversity transmission or for time diversity transmission based on the result of a comparison between threshold values and at least one of three criteria. The criteria includes a calculation of a smallest eigen value of a frequency channel response matrix and a smallest element of a diagonal of the matrix and a ratio of the largest and smallest eigen values of the matrix.

摘要： Contacts are managed within a contact center by associating each contact with one or more skill set and priority identifiers. The contacts may be represented as a software object. Contact (or contact objects) may be queued relative to one another by means of references to and/or from the object(s) immediately ahead of and behind each contact. For those contacts having multiple skill sets, a process and a system is disclosed wherein the multiple skill sets of the contact are serviced by multiple agents to provide a 1 to N process. The customer may be given the option to have each additional agent conference into a contact session thereby reducing the customer's overall wait time for the contact to be serviced. The process and system also may include identifying contact objects having prerequisites and routing those contact objects to an agent having one of the prerequisites. The process and system also allows a group of related contacts to be serviced by one or more agents in an M to 1 or M to N fashion. This is accomplished in part by determining if the contact has a common identifier associating the contact with a larger group and routing the contact to an agent or agents supporting contacts having the common identifier.
