  • Publication number: 20100113010
    Abstract: Techniques for originating a voice call by a UE after performing reselection with reprioritization are described. The UE may operate in an idle mode and may camp on a first wireless network of a first radio access technology (RAT), which may not support voice service. The first wireless network may have the highest priority among all wireless networks detected by the UE. The UE may receive an indication to originate a voice call. The UE may then perform reselection from the first wireless network to a second wireless network of a second RAT by modifying the priorities of the frequencies of the first wireless network and/or the second wireless network. The UE may then originate the voice call with the second wireless network, instead of the first wireless network, in order to avoid having to perform circuit-switched (CS) fallback from the first wireless network to the second wireless network.

  • Publication number: 20100046418
    Abstract: Systems and methodologies are described that facilitate providing relay nodes in wireless networks. In particular, cluster nodes, which can be regular eNBs, can provide wireless network access to the relay nodes over a backhaul link, and the relay nodes can offer access to devices or other relay nodes to expand network coverage and/or provide increased throughput. User equipment (UE) relays can function as UEs according to a cluster node such that UE relays receive network addressing and can tunnel communications through the cluster node using the backhaul link. Cell relays can function as a cell of the cluster node, such that transport layer communications terminate at the cluster node. In this regard, cell relays can define transport layers to use in communicating with the cluster nodes over the backhaul and with other devices over a provided access link.

  • Publication number: 20090303881
    Abstract: Methods and apparatus for network controlled mobile IP flow movement. An infrastructure node, such as a home agent, signals a mapping between care-of-addresses (CoAs) and flows to be transmitted from a mobile device in uplink communications. The CoA associated with each flow is determined from network, device, and/or flow information. A mobile node or mobile gateway receives the mapping and updates its local policy information. When a selected flow is to be transmitted in an uplink transmission, the local policy information is used to determine the CoA associated with the selected flow. The CoA is then used to determine an access network (or access path) on which the uplink transmission of the selected flow is to occur.

  • Publication number: 20090300207
    Abstract: Systems and methodologies are described that facilitate tunneling within wireless communication systems. Flow identification information is dynamically generated for data flows within a communication system. This flow identification information assists in determining appropriate flow specific policies to be applied with respective data flows. The flow identification information along with the flow specific policies can be communicated to an access mechanism which transmits the data flows in accordance with the flow specific policies. Different aspects relate to using source addresses in combination with the flow identification information for identifying different IP flows originating at a plurality of sources. The flow identification information also facilitates in verifying if different flows are transmitted in accordance with appropriate rules. The generated data flows are transmitted with respective flow identification information in order to facilitate the verification process.

  • Patent number: 7292861
    Abstract: The idea of the present invention is to enable the transmission of control information via several logical channels and to select the transmission channel dynamically by using a predefined selection rule. There are at least two logical channels that can be selected for the transmission of information. These logical channels should preferably include at least one signalling channel which is allocated in a connection-specific manner. The signalling channels which are allocated in a connection-specific manner can be signalling channels which use the capacity of the traffic channel or independent signalling channels which are allocated separately from traffic channels. At least one of the logical channels available for selection should preferably also be a shared channel allocated to several connections for joint signalling.

  • Patent number: RE41178
    Abstract: A method for duplex telecommunication connection in radio connections is based on a frame-structured interactive communication and a radio system where the frame-structured interactive communication is performed in the radio connections. A means is provided for improving the use of channel resources in implementation of interactive telecommunication connection by providing an FDD connection with one or more TDD dimensions. A full-duplex frequency band is time-duplexed into two or more sub-bands in which interactive communication takes place substantially independently. Transmissions in different transmission directions in each sub-band occur at different times, but simultaneous transmission can occur in different sub-bands in different transmission directions. The message is received entirely in one transmission direction before it needs to be responded to in another transmission direction in a particular sub-band.
