Patent ID: 7911965

Claim:
A method in a radio base station for performing a synchronized HSDPA (High Speed Downlink Packet Access)—related reconfiguration in a UTRAN (Universal Terrestrial Radio Access Network), characterised by the following steps: receiving a reconfiguration requesting message from a cell controlling entity of a radio resource server, the message comprising an SFN (System Frame Number) IE (Information Element) indicating a configuration switching time; performing a conversion of the SFN (System Frame Number) to a CFN (Connection Frame Number) sending a Radio Link updating message to the UE (User Equipment) controlling entity of a radio resource server, the message comprising a first activation time IE indicating said CFN, said first activation time being a CFN IE receiving an NBAP/RNSAP (Node B Application Part/Radio Network Subsystem Application Part) reconfiguration message from the UE controlling entity; deriving the SFN IE from said NBAP/RNSAP reconfiguration message; forwarding an RRC (Radio Resource Control) reconfiguration message to the UE, the message received from said UE controlling entity and comprising a second activation time IE, enabling the UE to switch to a new configuration at the point of time indicated by CFN switching to a new configuration at the point of time indicated by the SFN IE.
