Abstract

The present invention relates to method and arrangement in cellular mobile communication systems, in particular for handling of a physical random access channel for example in a Long Term Evolution communication network. By sending to at least one user equipment, UE, in a communication network cell an un-solicited speculative random access response, RAR, message comprising information relating to at least one of pre-amble identifier, allocated UE identifier, and uplink resource allocation data for L2/L3 message, it is possible to reduce the complexity of the access node, e.g. an eNodeB.
