Abstract:
The present invention relates to methods and arrangements for reducing the time delay associated with the initialization of a data transfer in a Universal Mobile Telecommunications Systems (UMTS) terrestrial radio access network (UTRAN). A Radio Network Controller (RNC) initiates a data transfer by transmitting a downlink paging message to a User Equipment (UE), wherein the UE is capable of being in the states URA PCH, CELL PCH or CELL DCH. The paging message comprises information for transferring the UE from the URA PCH or the CELL PCH state directly to the CELL DCH state by means of delay reducing information indicated in the paging message.
