Light connection control method and apparatus

A method of a first base station in a wireless communication system, the method comprising:

• receiving, from a core network, inactive state assistance information, the inactive state assistance information including at least one of discontinuous reception and transmission (DRX) information or mobility area information;
• determining whether a user equipment (UE) is moved to an inactive state based on the inactive state assistance information;
• and
• transmitting, to the UE, a control message including a UE identity associated with a UE context and a paging area configuration, in case that the UE is moved to the inactive state based on the inactive state assistance information.

A method of a second base station in a wireless communication system, the method comprising:

• receiving, from a user equipment (UE), a first control message for a location area update of the UE, in case that the UE in an inactive state moves out of a paging area based on a first paging area configuration;
• and
• transmitting, to the UE, a second control message in response to the first control message,
• wherein the second control message includes a UE identity associated with a UE context and a second paging area configuration.

A user equipment (UE) in a wireless communication system, the UE comprising:

• a transceiver;
• and
• a controller coupled with the transceiver and configured to:
• receive, from a first base station, a first control message including a UE identity associated with a UE context and a paging area configuration,
• enter into an inactive state based on the first control message,
• determine whether the UE in the inactive state moves out of a paging area based on the paging area configuration, and
• transmit, to a second base station, a second control message for a location area update of the UE, in case that the UE in the inactive state moves out of the paging area based on the paging area configuration.
