Abstract
The HSDPA (High Speed Downlink Packet Access)-related reconfigurations arc synchronized between a UTRAN (UMTS Terrestial Radio Access Network) and a mobile terminal (UE), by the Node B and the RNCs (Radio Network Controllers) providing the mobile terminal with a specific reconfiguration switching time. The reconfiguration switching time is either associated with the SFN (System Frame Number) or with the CFN (Connection Frame Number).
Claims14
A method in a radio base station for performing a synchronized HSDPA (High Speed Downlink Packet Access)—related reconfiguration in a UTRAN (UMTS 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 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 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 reconfiguration message from the UE controlling entity;
- deriving the SFN IE from said NBAP/RNSAP reconfiguration message;
- forwarding an RRC 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.
A radio base station in a UTRAN (UMTS Terrestrial Radio Access Network), arranged to perform a synchronized HSDPA (High Speed Downlink Packet Access)—related reconfiguration, characterized in
- a first receiving unit for receiving a reconfiguration requesting message from a cell controlling entity of a radio resource server, the message comprising an SFN (System Frame Number) IE, indicating a configuration switching time;
- a converting unit for performing a conversion of the SEW (System Frame Number) to a CFN (Connection Frame Number).
- a sending unit for sending a Radio Link updating message to the UE controlling entity of a radio resource server, the message comprising a first activation time IE indicating said CFN, the first activation time IE corresponding to a CFN IE.
- a second receiving unit for receiving an NBAP/RNSAP reconfiguration message from the UE controlling entity;
- an SFN-deriving unit for deriving said SFN IE from a NBAP/RNSAP reconfiguration message received from the UE controlling entity;
- a forwarding unit for forwarding an RRC 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;
- a switching unit for switching to a new configuration at the point of time indicated by said SFN IE.
