Method and apparatus for supporting handover in wireless communication system

A method by a base station for supporting handover in a wireless communication system, the method comprising:

• receiving, from a source base station, a handover request message for a terminal;
• storing, if first information on a measured result of handover parameters for a service based handover purpose and among a plurality of handover purposes, and second information on service types used by the terminal are included in the handover request message, the first information and the second information;
• and
• transmitting, to the source base station, a handover report including the first information and the second information, based on a handover failure of the terminal,
• wherein the handover failure is detected based on the handover report,
• wherein a service type associated with the handover failure of the terminal is determined from the service types based on the first information and the second base station, and
• wherein at least one handover parameter associated with the determined service type is adjusted in the source base station.

A base station for supporting handover in a wireless communication system, comprising:

• a transceiver configured to transmit and receive signals;
• and
• a controller configured to:
• control the transceiver to transmit, to a terminal, a message configuring at least one handover parameter for each of a plurality of handover purposes;
• control the transceiver to receive, from the terminal, a measurement report including first information on a measured result of handover parameters for a service based handover purpose among the plurality of handover purposes, and second information on service types used by the terminal;
• store the first information and the second information in a context of the terminal;
• control the transceiver to transmit, to a target base station, a handover request message for the terminal;
• determine service type associated with a handover failure of the terminal from the service types, based on the first information and the second information, in case that the handover failure of the terminal is detected;
• and
• adjust at least one handover parameter associated with the determined service type.

• and
• control the transceiver to transmit, to the source base station, a handover report including the first information and the second information, based on a handover failure of the terminal,
• wherein, when a reconnection request is received by the transceiver from the terminal, the controller is configured to control the transceiver to transmit, to the source base station, a handover report including the information for the specific handover purpose,
• wherein the handover failure is detected based on the handover report,
• wherein a service type associated with the handover failure of the terminal is determined from the service types based on the first information and the second base station, and
• wherein at least one handover parameter associated with the determined service type is adjusted in the source base station.
