  • Publication number: 20100159934
    Abstract: A method for controlling a handover and an apparatus are provided. The apparatus includes an interface to communicate with mobile units and a processing unit to determine a need for a mobile unit having more than one ongoing service connection to execute a handover and to send a handover command to the mobile unit through the interface, the handover command instructing the mobile unit to handover part of the ongoing service connections to a new network.

  • Publication number: 20100142478
    Abstract: A method and apparatus for enabling a network to provide information associated with neighboring network(s) of different access technologies to the wireless device, prior to the wireless device determining the need for a handover. When a determination is made by the network that a handover to a new access network is required, the network may send a message to the wireless device that commands the wireless device to leave a currently used access network. Alternatively, the network may send a message to the wireless device that guides or obligates the wireless device to select one of the access networks in the list, provided by the network, in case the wireless device chooses to make a handover. Upon receipt of a command message, the wireless device leaves a currently used access network either immediately or a reasonable time after having set up a connection to a new access network for ensuring smooth handover.

  • Patent number: 7706322
    Abstract: The disclosed embodiments relate to a method for arranging the transfer of packets between a wireless data transfer device (MS) and a mobile communication network (NW). For transferring packets between the wireless data transfer device (MS) and the mobile communication network (NW), temporary block flows (UL TBF, DL TBF) are formed, and information is transferred in these block flows in one or more packet data traffic channels (PDTCH) either in the first direction from the mobile communication network (NW) to the wireless data transfer device (MS) or in the second direction from the wireless data transfer device (MS) to the mobile communication network. In the method, information about the end of the block flow is set in a packet to be transmitted in a block flow when data transfer has stopped. When the transfer of packets in said first direction has stopped, at least one enquiry message is also sent from the mobile communication network (NW) to the wireless data transfer device (MS).

  • Publication number: 20090154443
    Abstract: A method and an arrangement for transferring information including delay sensitive data, such as speech and video data, in a packet radio service is provided. Data blocks are transmitted from a mobile station to a radio resource entity during a first active data transfer period using an uplink temporary block flow (TBF) connection. The uplink TBF connection is maintained during a passive period that follows the first active data transfer period, wherein during the passive period the mobile station does not send data blocks to the radio resource entity.

  • Publication number: 20080064401
    Abstract: A vertical handover decision to perform a seamless vertical handover of a wireless apparatus from a current access network to a target access network is established. When deciding to perform the vertical handover from the current access network to the target access network it can be considered whether an intermediate access network could be used. It can be decided that first a seamless vertical handover is performed from the current access network to an intermediate access network, and subsequently a seamless vertical handover from the intermediate access network to the target access network is performed.

  • Publication number: 20080008140
    Abstract: A system for managing the integration of a private short-range wireless network into a service/mobility domain. The private short-range wireless network may be converted into a semi-private short range wireless network by managing access to the network in accordance with rules defined by a home user. These rules allow a home user to define how visitors will be granted access to the semi-private short-range network when the user is at home or away. Restricted access may be enforced when the home user is present, and security measures may force the semi-private short-range wireless network to enter a safe mode when a condition is met.

  • Patent number: 7227839
    Abstract: The invention relates to arranging the transmission of packets between a mobile communication device and a mobile communication network. At least one temporary block flow is set up, and data is transmitted in packets in packet data traffic channels in a first direction from the mobile communication device to the mobile communication network. At the end of the transmission, information about the end of the block flow is set in the last packet, wherein the receiver of the packets acknowledges packet reception. After the end of the transmission of packets in said first direction, a determined time is waited until an acknowledgement is transmitted. If, while waiting, the mobile communication network detects a need for transmission of packets in the second direction from the mobile communication network to the mobile communication device, at least one packet data traffic channel is set up for data transmission in said second direction.

  • Patent number: 7215955
    Abstract: A method and system for restoring a subscriber context in a network element of a mobile communication network is described, wherein a new subscriber context which has been updated after the latest restart is indicated by transmitting a corresponding restart information to the network element. Based on the restart information the network element continues the use of new subscriber contexts updated after the latest restart and inactivates old subscriber contexts updated before the latest restart. Thereby, the amount of unnecessary subscriber context re-activations and the corresponding downtime of the service is reduced. Moreover, the amount of signaling required after the restart is reduced, since a smaller number of subscriber contexts have to be re-established.

  • Publication number: 20070061398
    Abstract: A method is shown for controlling content sharing towards a terminal during a teleconferencing session. The method comprises: establishing the teleconferencing session between at least a first and a second terminal; selecting, for the first terminal, a communication link having suitable link characteristics for sharing desired content during the teleconferencing session; observing, in the first terminal, changes occurring in the link characteristics of the communication link or in internal characteristics of the first terminal; in response to at least one predetermined parameter value of said link characteristics or said internal characteristics of the first terminal reaching a predetermined threshold, changing a conferencing capability of the first terminal. Optionally, an indication is then transmitted to at least one party of the teleconferencing session or to a conferencing bridge that the content sharing towards the first terminal is to be limited according to a rule included in said indication.
