  • Patent number: 8976757
    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.

  • Patent number: 8649786
    Abstract: A method is provided of registering a mobile terminal in an area of overlapping cell coverage by first and second networks for wireless mobile telecommunications. The networks are of different types. The method comprises: storing an identifier of the mobile terminal; storing in a controller a first record of in which cell or group of cells the mobile terminal is located in the first network and a second record of in which cell or group of cells the mobile terminal is located in the second network; and providing the mobile terminal with information of both records and said identifier.

  • Patent number: 8571555
    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.

  • Patent number: 8391149
    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.

  • Patent number: 8054806
    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.
