Patent ID: 8320929

Claim:
A method in a User Equipment (UE) to initiate a data transfer from the UE in a Universal Mobile Telecommunications System (UMTS) terrestrial radio access network (UTRAN), wherein the UTRAN comprises at least one Radio Network Controller (RNC) configured to connect to the UE, said UE configurable to be in one of the states UTRAN Registration Area Paging Channel (URA PCH), Cell Paging Channel (CELL PCH) or Cell Dynamic Host Configuration (CELL DCH), said method comprising the steps of: determining traffic volume to be transmitted; introducing delay reducing information by the UE into a data transfer initiating message, wherein the data transfer initiating message is an uplink cell update message transmitted by the UE and wherein the delay reducing information comprises information indicating whether the traffic volume of the data to be transmitted is above a pre-configured threshold without explicitly indicating said traffic volume; transmitting the data transfer initiating message by the UE; and, when said delay reducing information indicates that said traffic volume of the data to be transmitted is above said pre-configured threshold, receiving a message from the RNC comprising information to cause the UE to transfer from the URA PCH or the CELL PCH state directly to the CELL DCH state.
