Abstract
A method and apparatus for secondary base station change in a mobile communication system are provided. Method for secondary node change includes receiving conditional reconfiguration information from the base station, transmitting to the base station a first response message with a transaction identifier, performing evaluation based on the configuration generated by a second base station and transmitting a second response message with an identifier indicating which conditional reconfiguration is executed.
Claims5
A method by a terminal, the method comprising:
- receiving from a Master Node (MN) a first Downlink (DL) message, the first DL message includes a first identifier and one or more Conditional Reconfiguration Information Element (IE), each of the one or more Conditional Reconfiguration IE includes an execution condition and a second identifier and a second DL message;
- transmitting, to the MN, a first Long Term Evolution (LTE) Uplink (UL) message, the first LTE UL message includes the first identifier;
- performing a conditional reconfiguration evaluation based on a measurement configuration associated with Secondary Cell Group (SCG) if a first information indicating a measurement identifier refers to the measurement configuration associated with SCG is included in the Conditional Reconfiguration IE;
- and
- transmitting to the MN a second LTE UL message, the second LTE UL message includes a New Radio (NR) UL message and the second identifier, the second identifier is one of one or more second identifiers included in the first DL message, the second identifier corresponds to the second DL message that triggered conditional reconfiguration.

A terminal in a wireless communication system, the terminal comprising:
- a transceiver configured to transmit and receive a signal;
- and
- a controller configured to control the transceiver to:
- receive from a Master Node (MN) a first Downlink (DL) DL message, the first DL message includes a first identifier and one or more Conditional Reconfiguration Information Element (IE), each of the one or more Conditional Reconfiguration IE includes an execution condition and a second identifier and a second DL message;
- transmit to the MN a first Long Term Evolution (LTE) Uplink (UL) LTE UL (Uplink) message, the first LTE UL message includes the first identifier;
- perform a conditional reconfiguration evaluation based on a measurement configuration associated with Secondary Cell Group (SCG) if a first information indicating a measurement identifier identity refers to the measurement configuration associated with SCG is included in the Conditional Reconfiguration IE;
- and
- transmit to the MN a second LTE UL message, the second LTE UL message includes a New Radio (NR) UL message and the second identifier, the second identifier is one of one or more second identifiers included in the first DL message, the second identifier corresponds to the second DL message that triggered conditional reconfiguration.
