DEVICE AND METHOD FOR MAINTAINING SERVICE CONNECTION BY TERMINAL IN WIRELESS COMMUNICATION SYSTEM
First Claim
1. A method for providing a service by a target base station in a wireless communication system, the method comprising:
- if a terminal supports an on-going service that is a same service as that currently provided by a source base station, transmitting to the base station server, by the target base station, a service registration update request message that includes a request for re-establishment of a first bearer provided between the source base station and a base station server connected with the source base station;
receiving, from the base station server, a service registration update response message indicating that re-establishment of the first bearer is accepted; and
receiving, through the first bearer re-established between the target base station and the base station server, data associated with a service provided by the base station server so as to transmit the same data to the terminal.

Abstract
The disclosure relates to a 5G or a pre-5G communication system which will be provided to support a higher data transmission rate after a 4G communication system such as LTE. The present invention provides a method for providing a service by a target base station in a wireless communication system, the method comprising: when the target base station supports an on-going service, which is the same service as a service currently received by a terminal from a source base station, transmitting, to a base station server, a service registration update request message requesting a re-establishment of a first bearer provided between the source base station and the base station server connected to the source base station; receiving, from the base station server, a service registration update response message indicating that the re-establishment of the first bearer is accepted; and receiving data related to a service, provided from the base station server, through the first bearer re-established between the target base station and the base station server, and transmitting the data to the terminal.

11. A method for receiving a service by a terminal in a wireless communication system, the method comprising:
-
if a handover command message including information associated with a target base station, to which a handover is performed, is received from a source base station, performing the handover to the target base station; and if the target base station supports an on-going service that is a same service as that provided by the source base station, receiving, through a first bearer re-established between the target base station and the base station server, data associated with a service provided by a base station server connected with the target base station. - View Dependent Claims (12, 13)

16. A target base station for providing a service in a wireless communication system, the target base station comprising:
-
a transceiver; and a controller configured to control the transceiver to; if the target base station supports an on-going service that is a same service as that currently provided by a terminal from a source base station, transmit a service update request message for requesting re-establishment of a first bearer provided between the source base station and a base station server connected with the source base station, receive, through the first bearer re-established between the target base station and the base station server, data associated with a service provided by the base station server so as to transmit the same data to the terminal; and receive, from the base station server, a service registration update response message for indicating that re-establishment of the first bearer is accepted. - View Dependent Claims (17, 18, 19, 20, 21, 22)
