It is herein disclosed a wireless device, first and second radio network nodes and methods performed therein for communication. A method performed by a first radio network node for determining a global identity of a second radio network node which is a neighbour of the first radio network node is provided. The method comprises one or more of: receiving length information which specifies a length of the global ID of the second radio network node, from a wireless device which is served by the first radio network node; and determining the global ID of the second radio network node based on the length information.

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.

Scheduling of a Temporary Block Flow in a wireless communication system, wherein a type of Temporary Block Flow supported in the wireless communication system is evaluated () and a set of packet data channels pre-assigned to the Temporary Block Flow is identified. For a type of Temporary Block Flow supporting dynamic scheduling, carrier scheduling is performed by identifying timeslots () available for packet data scheduling for the Transmission Time Interval, determining a new set of packet data channels for potential scheduling to the Temporary Block Flow in the Transmission Time Interval, wherein the new set of packet data channels may include time slots on any carrier(s), and specifying () the packet data channels selected for potential scheduling for the Temporary Block Flow as a subset of packet data channels within the pre-assigned packet data channels. Packet data channels are allocated () for the Temporary Block Flow in the Transmission Time Interval. The Temporary Block Flow is scheduled () to the set of packet data channels.

Dynamic temporary block flow scheduling

In a method in a central node of a cellular radio network the central node is adapted to deciding if a mobile station connected to the cellular radio network via a first radio access technology controlled by the central node is to be moved to another radio access technology when a circuit switched call of the mobile station is ended. It is assumed that the cellular radio network is adapted to use a fallback to circuit switched procedure. First it is decided that a CS call for a particular mobile station has ended. Then in it is checked if the CS call was the result of a fallback to CS procedure. The central node then decides if the mobile station is to be moved to another radio access technology based at least partly on the, i.e. if the CS call was a result of a CS fallback procedure.

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.

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.

A method of alternative routing of a service request in connection with a poolof integrated core network nodes. Before a serving radio access node routes a service request to the core network node serving a mobile station it checks if there are any idle terrestrial transmission resources available between the serving radio access node and the serving core network node. If idle resources are available, the service request is routed to the serving core network node. If no idle resources are available, the service request is rerouted to a selected one of the other core network nodes the pool that has idle resources available. The selected core network node receives the service request, recognizes it contains no temporary identification (TMSI) number associated with it and therefore sends an identity request to the mobile station. The identity request triggers the mobile station initiate an update location registration at the selected core network node or at any of the other core network nodes in the pool. The selected core network node or said other network node now acts as serving core network node for the mobile station. Next time the mobile station makes a service request the radio access node routes it to said selected or said other network node to which it hopefully are idle terrestrial transmission resources available.

Routing based on transmission utilization

A 2G controlling entity in a common 2G/3G network that includes a common Core Network is connected to dual mode mobile stations and to a 3G controlling entity also connected to dual mode mobile stations. The 2G controlling entity applies a 3G camping strategy and receives a service request, for a service at least supported by the 2G network, from a dual mode mobile station. The 2G controlling entity instructs the dual mode mobile station, when connected to the 2G network, to perform cell reselection evaluation of 3G network cells only when the 2G network signal strength is below a predetermined threshold.

An enhanced radio network controller (RNC) node of a radio access network stores context information for a user equipment unit which is in a Connected Mode, and initiates a cell update-prompting message which is transmitted the user equipment unit. The stored context information is used by the context-enhanced radio network controller (RNC) node for addressing the cell update-prompting message to the user equipment unit. After the user equipment unit (which is in its Connected Mode) performs the prompted cell update procedure, such user equipment unit (UE) can be paged with a conventional paging message. The invention with its context-enhanced radio network controller (RNC) node is particularly suitable to user equipment units which are in a critical state of the Connected Mode, such as (for example) either a CELL_PCH state or a URA_PCH state of the Connected Mode.
