Abstract: IMS technology can allow service providers to share services with each other over different IMS networks. A SCIM can operate with ISC and COPS interfaces to communicate with another similarly situated SCIM to monitor and query information from applications servers operating in IMS networks. When a mobile phone from a home IMS network roams in a visited IMS network, the mobile phone can access features through a tunnel back to the home IMS network while operating in the visited IMS network. The mobile may also access features in the visited IMS network.

Abstract: A network terminal has communication section that communicates with other network terminals connected via a network, time-series data creation section that, at timing set beforehand, creates time information including a correspondence between an identification number of the own network terminal and a current time measured by a timer of the own network terminal and creates time-series data registering the time information, and additional registration section that, when the communication section receives the time-series data transmitted from another network terminal, creates time information including a correspondence between the identification number of the own network terminal and a current time measured by the timer of the own network terminal and additionally registers the time information to the time-series data received this time.

Abstract: A method and an apparatus for augmenting timing synchronization in a base station using backhaul network frequency synchronization are provided. When in a first mode an external time epoch reference synchronized with system time is used to synchronize the base station to system time. When in a second mode a network frequency reference recovered from a backhaul network link is used to maintain the timing synchronization.

Abstract: A system for interfacing a client system in a first network domain with a Provider Link State Bridging (PLSB) domain includes at least two Backbone Edge Bridges (BEBs) of the PLSB domain. Each BEB is an end-point of a connection in the first network domain to the client system and an end-point of at least a unicast path in the PLSB domain. An inter-node trunk is provided in the PLSB domain for interconnecting the BEBs. A phantom node is defined in the PLSB domain and is notionally located on the inter-node trunk. Each of the BEBs is configured such that: an ingress packet received from the client system via the connection in the first network domain is forwarded through a path notionally rooted at the phantom node; and an egress packet destined for the client system is forwarded to the client system through the connection in the first network domain.

Abstract: Systems and methodologies are described that facilitate multiple-phase selective connection establishment in wireless communications networks. Radio resource control (RRC) layer communications can be instantiated between a mobile device and base station. Additional information can be required by a downstream network component regarding the mobile device. Accordingly, the RRC resources can be utilized to transmit the additional information from the mobile device to the network component to facilitate the multiple-phase establishment. This can be accomplished using non-access stratum (NAS) messages. Further, the information can relate to authorization, security re-configuration, context re-synchronization, an identity of the mobile device, and the like.

Abstract: The present invention relates to a broadband wireless access system, and more specifically, to a method and apparatus for efficiently allocating resources to terminals in a random access system. The method for performing such a random access procedure of a terminal in a broadband wireless system according to one embodiment of the present invention comprises: transmitting a preamble sequence to a random access region in a base station; and receiving from the base station ACK information indicative of a received state of the preamble sequence. The ACK information receiving step is preferably a step of decoding a map information element that is masked as an identifier of the random access region.

Abstract: Systems, methodologies, and devices are described that facilitate transmitting a guard time parameter to a mobile device to facilitate rate matching data around a guard time region associated with a downlink subframe of a radio frame sequence. A base station transmits the guard time parameter via PBCH or DBCH to the mobile device. The base station rate matches data associated with PDSCH, comprising DBCH, around the guard time region, and transmits PDSCH to the mobile device. The mobile device identifies the guard time parameter and rate matches at least a portion of the information received via the PDSCH around the guard time region to facilitate enhanced reception of PDSCH. Optionally, a radio frame sequence can be structured so that a subframe immediately following a subframe containing DBCH is a downlink subframe, which can be known by the mobile device a priori or based on a downlink subframe parameter.

Abstract: In a system for providing an IPTV service, if a multicast address of an IPTV channel received from a head-end is a multicast address requested by a mobile node through a tunnel, an end router confirms a care of address (CoA) of the mobile node corresponding to the multicast address of the IPTV channel, sets the multicast address in the first header of broadcasting traffic, sets the CoA of the mobile node in the second header of the broadcasting traffic, and then sends the broadcasting traffic.

Abstract: A method for wireless communication comprises a donor enhanced Node B (eNB) transmitting system information for a subframe structure to a relay node (RN), which information comprises radio resource configuration and/or timing information for uplink backhaul transmission. The RN uses an automatic method to select the Round Trip Time (RTT) value for the Hybrid Automatic Repeat request (HARQ) on the uplink backhaul (Un) relay link. The RTT value is implicitly determined according to the Un (backhaul) subframe or MBSFN subframe configuration periodicity. The RTT option is signaled by the Un subframe configuration period of the MBSFN Un downlink signals.

Abstract: In general, this disclosure describes techniques of selecting routes for network packets through a computer network based, at least in part, on electrical power procurement arrangements of devices in the computer network. A computing system includes a hardware processor and a database storing power procurement profiles. Each of the power procurement profiles stores data indicating an arrangement between an operator of one or more of routing devices to procure electrical power from a utility company for facilities in which the routing devices are located. The power procurement profiles are mapped to ranges of network addresses associated with the facilities for retrieval of the power procurement profiles for the routers based on the network addresses assigned to the routers.

Abstract: Random access coverage is assured while at the same time supporting high uplink data rates in a same service area served by a base station. A set of radio resources are shared by multiple mobile terminals for transmitting uplink to the base station including requests for access to service from the base station and transmissions for active connections with the base station. A first repeating time period and a second different repeating time period are defined. Uplink transmission grants are scheduled for active connections that permit use of a greater amount of the radio resources during the first repeating time period. Uplink transmission grants are also scheduled for active connections that permit use of a smaller amount of those resources during the second repeating time period. At least some random access requests to the base station are controlled to occur only during the second repeating time period.

Abstract: A method and apparatus for coordinating communication in a wireless sensor network may include a plurality of nodes, such as routers, edge nodes, data accumulators and/or gateways. Time management functions, such as determining an elapsed time, may be controlled based on a detected temperature, e.g., a temperature detected at a node, and/or based on a detected clock skew between two or more clocks in two or more different devices. Accurate time management may allow for devices to more accurately coordinate communication instances, e.g., communication that occurs at periodic wake up times. A cluster head, such as a data accumulator, may be associated with a network after its initial formation and cause nodes in the network to alter their hierarchy in the network, thereby making the cluster head accumulator a parent to nodes in the network. Nodes having a relatively lower hop count may have a higher battery capacity than nodes having a higher hop count.

Abstract: A radio base station includes a mobile communication system, a first relay node and a radio base station connected via a radio bearer, a second relay node and a radio base station connected via a radio bearer, and a mobile station configured to conduct a handover process between a first and second state. In the first state a radio bearer is established with the first relay node in order to communicate via the first relay node and the radio base station. In the second state a radio bearer is established with the second relay node in order to communicate via the second relay node and the radio base station. The mobile station is configured such that control signals are transmitted and received via the radio bearer between the first relay node and the radio base station, via the radio bearer between the second relay node and the radio base station.

Abstract: This description relates to access terminal hand-off methods in wireless networks.

Abstract: Systems and methodologies are described that facilitate synchronizing base stations in a wireless communication environment. A base station can receive a synchronization signal sent via a low reuse channel, which can be shared by a group of base stations. Further, the base station can align a clock associated therewith to the received synchronization signal. Moreover, the base station can coarsely align the clock to a first synchronization signal received upon a first subset of resources of the low reuse channel, and finely align the clock to a second synchronization signal received upon a second subset of resources (e.g., of the low reuse channel, of a separate channel, . . . ), where the second subset of resources can be reserved for transmission from at least one base station with at least a predetermined level of synchronous accuracy.

Abstract: Aspect of the present disclosure include A Mobile Ad Hoc Network (MANET) in which an intermediate relay node may engage in discreet packet-dropping practices for selfish (e.g., to conserve power) or other reasons. Each node in such a MANET has a dynamic reputation level known to all other nodes. Embodiments include improving the overall performance or robustness of such a MANET by adopting a routing strategy (e.g. routing protocol) which considers the reputation levels of intermediate relaying nodes in determining the best route from a source to a destination. Embodiments of the present disclosure also include a system for discovering a route between two nodes in a communication network. One or more nodes: (i) determine a reputation level of each neighboring node; (ii) sending a route discovery message that is addressed to the destination node to one neighboring node having a highest reputation level.

Abstract: A communication system, network, interface, and port architecture are provided for transporting data across a ring network. A network node operating as a first timing master generates a set of frames, each frame having a preamble, a data field and a time count field, which represents a portion of the time information associated with the set of frames. This time information may include counted time units, like seconds, or a number of generated and transmitted over the network. As the individual frames of a set of frames are generated and sent on the network, they pass other network nodes and are forwarded through the ring bus to the first timing master which receives at least a portion of the set it is still generating. This enables a received time count field to be compared with a transmitted time count field of the same set. If the fields are identical, there is no other timing master on the bus.

Abstract: A method and apparatus for dynamically adjusting traffic quality of service (“QoS”) on-demand over a communications network are disclosed. The process, in one embodiment, is configured to receive an enhanced QoS request from a user via a first node over a communications network. Upon prioritizing traffic flow in accordance with the enhanced QoS request, the enhanced QoS request associated with the first node is recorded. Upon acknowledging the enhanced traffic QoS, the process routes the information to the first node in accordance to a predefined enhanced QoS.

Abstract: Methods and apparatus for processing a downlink (DL) subframe of an orthogonal frequency-division multiplexing (OFDM) or an orthogonal frequency division multiple access (OFDMA) frame are provided. By arranging the DL-MAP information elements (IEs) in a DL-MAP of the DL subframe to correspond chronologically to the arrangement of their associated data bursts in the OFDM or OFDMA frame at a base station (BS), a user terminal receiving that frame may be able to start decoding the data bursts in the DL subframe without having to wait until all of the DL-MAP IEs have been parsed and decoded. In this manner, the user terminal may decode the data bursts while simultaneously parsing a remaining portion of the DL-MAP, and the time for processing the entire frame may be reduced, thereby increasing the processing speed.
