The embodiments herein relate to a method in a target RAN node for enabling source based selection of a serving operator which should serve a wireless device in a target shared network. During handover, the target RAN node receives the serving operator that should serve the wireless device in the target shared network. After the handover, the target RAN node transmits a request for the IMSI and receives a response with the IMSI. The target RAN node obtains information about the serving operator stored during the handover. The target RAN node determines a target CN node served by the serving operator if the target shared network is a MOCN network. The target RAN node transmits information indicating the serving operator to the target CN node if the target shared network is a GWCN network.

Source based selection of serving operator

Methods, network control nodes, network nodes and user equipments for assisting the updating of neighbor cell information when a new cell is introduced, or added, to an already existing radio access network are described in this disclosure. According to an example embodiment a signal is transmitted, from a first network control nodeassociated with RANto a second network control nodeassociated with RAN. This signal comprises a cell identity CI, e.g. a Local Cell Identity LCI, of the newly introduced cell C, which is added to RAN. Next, the second network control nodeof RANreceives the signal comprising the cell identity CIof this newly introduced cell C. In response, the second network control nodetransmits, to at least one user equipmentassociated with the RAN, a signal comprising the received cell identity CIof the newly introduced cell Cas well as a request to the at least one UEassociated with RANto search for the newly introduced cell Cof RAN, which is controlled by network node

Updating of neighbor cell information in a radio communications system

The present invention relates to a control node for a mobile communication network. The control node has means arranged to provide the IMSI of at least some of the currently set up connections and means arranged to allocate resources for the connections based on said IMSI information. The present invention also relates to a method for allocating resources for a connection in a mobile communication network.

Control node for a mobile communication network and a method for allocating resources in said network

Handover control in a control node, said control node controlling allocation of radio resources in a first set of cells belonging to at least two different Public Land Mobile Networks, said first set of cells including at least a first subset of cells belonging to a first Public Land Mobile Network and a second subset of cells belonging to a second Public Land Mobile Network. Traffic load exceeding a predefined level is detected () in a first cell belonging to the first subset of cells. In response to said detecting, connections in the first cell are evaluated () to find one or more connections which could be supported by radio resources in one or more cells in the second subset of cells having capacity for handling additional traffic load. Handover is ordered () of at least one of said one or more connections to said one or more cells in the second subset of cells.

Inter-PLMN handover in a shared radio network

Methods and apparatus in a base station controller (BSC) or equivalent node for sharing a pool of radio transceivers are described. The BSC belongs to a first wireless telecommunication network, the pool of radio transceivers includes first radio transceivers for a first radio base station (RBS) belonging to the first wireless telecommunication network and second radio transceivers for a second RBS belonging to a second wireless telecommunication network, and the first and second radio transceivers have substantially the same geographic coverage. A method includes selecting a radio transceiver from the pool irrespective of whether the radio transceiver selected is a first radio transceiver or a second radio transceiver; and allocating a communication channel provided by the selected radio transceiver to a respective mobile station registered in at most one of the first and second telecommunication networks.
