Abstract: An Uplink control channel resource Management Module (120, 130), referred to as “UMM”, and a method in the UMM for assigning, to a radio network node 110, uplink control channel resources, referred to as “UCCHR”, for use in a uplink control channel between the radio network node (110) and a communication device (160) are provided. The UMM obtains (210) resource allocation information, referred to as “RAI”, and generates (220) a resource allocation command, referred to as “RAC”, based on the RAI. The RAC indicates UCCHR to be used by the radio network node. Furthermore, the UMM provides (230) the RAC to the radio network node (110). Related methods and nodes to enable the UMM to assign UCCHR are also provided.

Abstract: In one aspect of the invention presented herein, a mobile terminal requests positioning assistance data from its supporting wireless communication network, in response to receiving a positioning request from a positioning node. Further, in response to receiving the positioning assistance data from the network, the mobile terminal sends the positioning assistance data to the positioning node. In this manner, the positioning node advantageously gains access to network-generated positioning assistance data without need for requesting it from the network. In at least one embodiment, the mobile terminal receives the positioning request from the positioning node over a User Plane (UP) connection. However, the mobile terminal sends the positioning assistance data request to the base station over a Control Plane (CP) connection, and receives the requested positioning assistance data via the CP. The terminal transfers that data to the UP and sends it to the positioning node.

Abstract: A method and arrangement for handover wherein the handover resource (the dedicated random access preamble) is reserved by the target radio base station (RBS) for a limited period of time, thus increasing the handover efficiency and thereby allowing random access preambles to be used for initial access to a larger extent. The information about the reserved time interval is sent to the UE in the handover command message by means of a frame number offset between the source RBS and the target RBS. The UE uses the information to calculate when to send its synchronisation message to the target RBS. The frame number offset is calculated either by source RBS or by target RBS.
