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:
- transmitting, to a low latency base station server that uses a low latency layer to communicate between an application layer and a data link layer, a first request message for a re-establishment of a first bearer between the target base station and the low latency base station server, the first request message including at least one of an ID of a terminal, an ID of a source base station, an ID of the target base station, and an ID of a bearer between the source base station and the low latency base station server;
receiving, from the low latency base station server, a first response message indicating that the re-establishment of the first bearer is accepted;
receiving, through the first bearer, first data associated with a service provided by the low latency base station server; and
transmitting, to the terminal, the first data.

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.

8. A method for receiving a service by a terminal in a wireless communication system, the method comprising:
-
receiving, from a source base station, a handover command message including information associated with a target base station, to which a handover is performed; performing the handover to the target base station; and receiving, through a first bearer re-established between the target base station and a low latency base station server that uses a low latency layer to communicate between an application layer and a data link layer, first data associated with a service provided by the low latency base station server, wherein the first bearer is re-established based on at least one of an ID of the terminal, an ID of the source base station, an ID of the target base station, and an ID of a bearer between the source base station and the low latency base station server. - View Dependent Claims (9, 10)

11. 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; transmit, to a low latency base station server that uses a low latency layer to communicate between an application layer and a data link layer, a first request message for a re-establishment of a first bearer between the target base station and the low latency base station server, the first request message including at least one of an ID of a terminal, an ID of a source base station, an ID of the target base station, and an ID of a bearer between the source base station and the low latency base station server; receive, from the low latency base station server, a first response message indicating that the re-establishment of the first bearer is accepted; receive, through the first bearer, first data associated with a service provided by the low latency base station server; and transmit, to the terminal, the first data. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A terminal for receiving a service in a wireless communication system, the terminal comprising:
-
a transceiver; and a controller configured to; receive, from a source base station, a handover command message including information associated with a target base station, to which a handover is performed; perform the handover to the target base station; and receive, through a first bearer re-established between the target base station and a low latency base station server that uses a low latency layer to communicate between an application layer and a data link layer, first data associated with a service provided from the low latency base station server, wherein the first bearer is re-established based on at least one of an ID of the terminal, an ID of the source base station, an ID of the target base station, and an ID of a bearer between the source base station and the low latency base station server. - View Dependent Claims (19, 20)
