Abstract: Network node and base station and methods therein for deriving a permanent identifier, such as an IMSI, for a UE in a cellular communication system of LTE type. The solution involves the use of a request for an inter-RAT handover, where the request comprises a temporary identifier of a process associated with the UE of which a permanent identifier is to be derived. The access to a permanent UE identifier is enabled in a radio access network where such an identifier is not readily available. The solution does not require any changes to procedures or nodes in the core network.

Abstract: A network node (28) of a radio access network (20) comprises a scheduler (40) configured to provide an allocation of an uplink resource to an indoor wireless terminal (30) in communication over an air interface with the radio access network. The allocation of the network node is made in coordinated manner with resource allocation of another network node whereby any interference by reason of allocation of same uplink resource must be with another indoor wireless terminal served by the another network node. Preferably the another network node is a network node which serves a neighboring or adjacent cell.

Abstract: In a cellular communications system the antenna tilt may be varied in order to achieve different degrees of overlap between different cells, in dependence of the service being transmitted. For a broadcast service the antenna tilt may be set to maximize the overlap, while for a data or speech connection the antenna tilt may be set to minimize the overlap.
