  • Publication number: 20090296654
    Abstract: A method is provided of transferring a call connection with a mobile terminal from a first network to a second network. The first network is capable of handling both circuit-switched and packet-switched modes of connection. The second network is capable of handling one of the packet-switched or circuit-switched modes of connection but not both. The terminal is capable of both packet-switched and circuit-switched call modes of connection. The method comprises the first network: identifying the location of the mobile terminal with respect to at least one of the networks, identifying the mobile terminal as being in a mode of connection not usable in the second network, instructing the mobile terminal to transfer the call connection to the other mode of connection, and transferring the call connection to the second network.

  • Publication number: 20090263918
    Abstract: Methods and apparatuses are provided for calibrating eddy current sensors. A calibration curve is formed relating thickness of a conductive layer in a magnetic field to a value measured by the eddy current sensors or a value derived from such measurement, such as argument of impedance. The calibration curve may be an analytic function having infinite number terms, such as trigonometric, hyperbolic, and logarithmic, or a continuous plurality of functions, such as lines. Such curves can reduce the number of wafers used in the calibration of the sensors while providing higher accuracy over a larger thickness range. High accuracy allows the omission of optical sensors, and use of eddy current sensors for endpoint detection, transition call detection, and closed loop control in which a process parameter is changed based on the measured magnetic flux density change in one or more processing zones.

  • Publication number: 20090124260
    Abstract: The present invention provides methods involving at least one mobile unit configured to receive wireless connectivity using first and second wireless communication systems that operate according to first and second radio interface technologies, respectively. The first and second radio interface technologies are different. The method may include determining, in response to the mobile unit handing off from the first to the second wireless communication system, session establishment information for the second wireless communication system based on session establishment information associated with the first wireless communication system.

  • Publication number: 20090046662
    Abstract: In handover in a wireless telecommunications network, dummy packets, or data packets with an indicator bit, are transmitted from a gateway node MME/SAE GW 4 to a source node eNB 2 when there is no more data being sent to the source node 2. The source node 2 forwards them to a target node eNB 3. When the target node eNB 3 detects the indictors, it knows that there is no more data awaiting to be received from the source node 2 and it can continue with data sent from the SAE GW to it instead.

  • Publication number: 20090047965
    Abstract: A method for handover of a mobile terminal from a source node to a target node in a wireless telecommunications network, including the steps of: adding an indication in the preparation phase by which source node indicates to the target node if it is the one preferred or not. If a target node is not the one preferred but is still selected by the UE, it may indicate this to the source node as by a specific new message that comes earlier in the handover process than a message requesting the source node to release resources following successful handover to a new node. The source node can then in this case cancel handover preparations to other target nodes earlier and also start data forwarding where applicable earlier.

  • Publication number: 20090046660
    Abstract: According to an aspect of the invention, a method for handover of a mobile terminal from a source node to a target node in a wireless telecommunications network includes the steps of making data forwarding of fresh data optional irrespective of the RLC mode, which may involve RLC-UM or RLC-AM bearers. The method may include providing an explicit instruction to the mobile terminal for each bearer on whether a bearer is subject to data forwarding or not. This may then be used by the mobile terminal to handle the buffered packets and PDCP SNs.

  • Publication number: 20090046661
    Abstract: In handover in a wireless telecommunications network, dummy packets, or data packets with a last used sequence number indicator are transmitted from a source node eNB 2 to a target node 3. When the target node eNB 3 detects the information, it knows the sequence of data packets being received from the source node eNB 2 and which is the last one and its sequence number. Thus, data packets may be suitable ordered for delivery to a mobile terminal UE 1.

  • Publication number: 20090046578
    Abstract: In a wireless network, for example, an LTE network, the context information relating to a mobile terminal UE is transmitted to a plurality of network nodes eNB 2, 3 and 4 from a source network node, eNB 1. One of the eNB 2 is a handover target node and also reserves resources for the UE in anticipation of receiving it after handover. The other eNBs 3 and 4 do not reserve resources. In the event of radio link failure, the UE may attach to one of the designated eNBs 3 and 4 that have not reserved resources, but that do recognize the UE because they have received its context. The method reduces the likelihood of the UE needing to go via the time consuming IDLE state while only reserving resources at a handover target eNB.

  • Publication number: 20080049772
    Abstract: Disclosed is a method of transmitting data from a plurality of traffic flows based on a quality of service indicator which indicates a manner of partitioning a rate grant such that more than one traffic flow, if desired, may simultaneously use the rate grant thereby avoiding rate grant starvation by one or more traffic flows. The method of transmitting data from a plurality of traffic flows comprises the steps of extracting data from one or more buffers based on the quality of service indicator and the rate grant, and transmitting a block of data comprising the extracted data wherein the one or more buffers are associated with one or more traffic flows.

  • Patent number: 7016679
    Abstract: A mobile telephone network provides a network operator domain in which the output from a radio network controller (RAN) is processed by a voice capable serving GPRS support mode (VC-SGSN). The VC-SGSN consists of the combination of a voice service box (VSB) and a service GPRS support node (SGSN). The VSB and the SGSN can jointly access the same home location register). The output of the SGSN can be forwarded to the internet via a gateway GPRS support node while the output of the VSB can be forwarded to the public switched telephone network (PSTN).
