Method and system for supporting fast recovery of user equipment

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

• a transceiver;
• and
• a controller coupled with the transceiver and configured to:
• receive a first radio resource control (RRC) message from a terminal,
• transmit an information request message associated with the terminal to a second base station,
• receive an information response message associated with the terminal from the second base station,
• transmit a path switch request message to a mobility management node associated with the terminal based on the information response message,
• receive a path switch response message from the mobility management node associated with the terminal, and
• transmit information associated with releasing a context of the terminal to the second base station based on the path switch response message.

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

• receiving an information request message associated with a terminal from a first base station;
• performing a security check based on the information request message associated with the terminal;
• transmitting an information response message associated with the terminal to the first base station based on a success of the security check;
• and
• receiving information associated with releasing a context of the terminal from the first base station.

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

• a transceiver;
• and
• a controller coupled with the transceiver and configured to:
• receive an information request message associated with a terminal from a first base station,
• perform a security check based on the information request message associated with the terminal,
• transmit an information response message associated with the terminal to the first base station based on a success of the security check, and
• receive information associated with releasing a context of the terminal from the first base station.

A method by a terminal in a wireless communication system, the method comprising:

• transmitting a first radio resource control (RRC) message to a first base station;
• and
• receiving a second RRC message associated with an RRC connection from the first base station,
• wherein an information response message associated with the terminal is transmitted from the first base station to a second base station based on reception of the first RRC message,
• wherein the second RRC message associated with the RRC connection is transmitted from the first terminal, based on reception of an information response message associated with the terminal at the first base station,
• wherein the information request message includes a base station application protocol (AP) identifier for the UE allocated by the first base station, and
• wherein the information response message includes at least one of a base station AP identifier for the UE allocated by the first base station or a base station AP identifier for the UE allocated by the second base station.
