  • Method for recovery from a failed handover procedure in a telecommunication system
    Patent number: 8644252
    Abstract: The present invention relates to a method, a user equipment and a network node in a cellular radio network. According to the method of the present invention, the network units detects a failed transmission of a handover command to the UE, which is still having a uplink channel available, and further receives a RRC message from the UE indicating the loss of a serving cell and indicating the strongest cell. The network unit prepares and initiates a new serving cell re-establishment and sends to the UE a RRC reconfiguration message. The UE can then continue normal operation in the new cell.

  • Method of transmitting data block information in a cellular radio system
    Patent number: 8467822
    Abstract: A method in a transmitter for transmitting a transport format indication from a transmitter to a receiver (505) where each value of the transport format indication identifies at least two transport block sizes. Hereby a more flexible use of different transport block sizes is enabled.

  • Method for reducing uplink traffic load on transport network at basestation during soft handover
    Patent number: 8010115
    Abstract: The present invention relates to a node and a method thereof for a mobile telecommunication network connectable to a controlling node and wirelessly connectable to mobile terminals. The node is adapted to have an uplink connection to a mobile terminal, wherein the mobile terminal is adapted to have a second uplink connection to at least a second node such that data transmitted from the mobile terminal may be received at the node and at the at least the second node. The node comprises means for estimating whether data transmitted from the mobile terminal received at the at least the second node is received stronger than the data received at said node and means for discarding data received from the mobile terminal if it is estimated that the data is received stronger at the at least the second node than the data received at said node.

  • Uplink congestion detection and control between nodes in a radio access network
    Patent number: 7724656
    Abstract: Congestion in a radio access network (RAN) associated with transporting uplink information originating from one or more mobile terminals is detected. That detected RAN congestion is reduced using any suitable technique (several examples are described) and may be implemented in one or more nodes in the RAN. One advantageous (but non-limiting) application is to a RAN that supports high speed uplink packet access (HSUPA) and/or one or more enhanced uplink dedicated channels (E-DCHs).
