A method of operating a radio access network (RAN) node includes determining whether packet duplication is activated for a split data radio bearer (DRB), associated to a user equipment (UE) and initiating transmission of an indication toward a trace collection entity of whether packet duplication is enabled for the DRB. A method of operating a management node of a core network of a wireless communication system according to some embodiments includes transmitting a minimization of drive testing (MDT) configuration associated to a UE towards a network node, receiving an indication of whether packet duplication is enabled for a split DRB associated to the UE, and adjusting how throughput is calculated for the UE based on the indication.

Packet duplication indication for MDT

A radio device () is configured with multiple applications. For each of the multiple applications, the radio device () determines at least one characteristic of traffic generated by the application. In response to one of the applications requiring establishment of a connection of the radio device () to the cellular radio network, the radio device () sends a request () for establishing the connection to the cellular radio network, the request () indicates the at least one characteristic corresponding to the application.

Traffic characteristic indication for connection establishment control

A method for evaluating a connection between a first network node and a User Equipment (UE) via a second cell. The first network node serves a first cell. A sending of a first message is initiated. The first message is sent from the first network node to the UE via the second cell. The first message comprises a trigger for the UE to respond by sending a second message comprising feedback relating to the connection to the second cell. A time value difference between the sending of said first message and receiving of said second message in the first network node is obtained. The second message comprises the feedback relating to the connection sent from the UE in response to the first message. Then it is evaluated how the connection shall be used based on the obtained time value difference and the received feedback.

Methods and network nodes for evaluating a connection

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.

Methods and apparatus for transceiver allocation in mobile communication networks

In a method and a device for controlling the output power in a Base Transceiver Station adapted to transmit signals over an air interface using a power amplifier for multiple earners, the power of signals to be transmitted in an upcoming transmission time slot are added and compared to at least one threshold value. If the threshold is exceeded the output power is reduced. By implementing a power reduction scheme as set out above the risk for peak power effects is minimized at the same time as the dimensioning may be aggressive. This is made possible because no power will be backed off unless really needed.

Transmit power control for base stations using multiple carrier power amplifiers

Management information is determined for both non-drifting and drifting mobile radios being serviced by a cell and/or by an RNC and reported to a management system for further processing. A distribution of drifting mobile radios to non-drifting mobile radios in a particular cell (or for all cells controlled by another RNC) is determined using the number of established radio links in the cell (or cells) for both drifting and non-drifting mobile radios. The distribution along with management information detected for non-drifting mobile radios are used to estimate corresponding management information for drifting mobile radios. In this way, management information for both drifting and non-drifting mobile radios is reported to the management system using existing formats, protocols, and procedures in both the traffic and management systems.
