Device, base station, and control methods thereof in wireless communication system
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A control method of a device according to one embodiment of the present invention may comprise the steps of: receiving, from a first base station, information on at least one second base station existing within a critical distance from the first base station; and determining, on the basis of the information, whether a wireless communication system of the at least one second base station is to be used.
1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a first base station related to a first a radio access technology (RAT), at least one message including location information of a second base station related to a second RAT;
identifying mobility information of the terminal;
determining whether the terminal is to be located within a coverage of the second base station based on the location information of the second base station and the mobility information of the terminal;
generating a signal for connecting to the second base station based on a result of the determination; and
after connecting to the second base station, determining whether the terminal is to be located outside the coverage of the second base station based on the location information of the second base station and the mobility information of the terminal.
2. The method of claim 1 , wherein the at least one message further includes at least one of a public land mobile network (PLMN) identifier of the second base station, and coverage information of the second base station.
3. The method of claim 1 ,
wherein the at least one message further includes information associated with a signal strength of the second base station, and
wherein determining whether the terminal is to be located within the coverage of the second base station comprises generating a database for a quality of the second RAT based on the information associated with the signal strength of the second base station.
4. The method of claim 1 , further comprising:
identifying a number of the at least one message received from the first base station, in case that the terminal is connected to the second base station; and
determining whether to maintain a connection to the second base station, based on the number of the at least one message received from the first base station.
5. The method of claim 1 , further comprising displaying a screen to notify that the second RAT is to be terminated, based on a result of the determination that the terminal is to be located outside the coverage of the second base station.
6. The method of claim 1 , further comprising determining to connect to the first base station based on a result of the determination that the terminal is to be located outside the coverage of the second base station.
7. A terminal in a wireless communication system, the terminal comprising:
a transceiver; and
a controller coupled with the transceiver and configured to:
receive, from a first base station related to a first a radio access technology (RAT) via the transceiver, at least one message including location information of a second base station related to a second RAT,
identify mobility information of the terminal,
determine whether the terminal is to be located within a coverage of the second base station based on the location information of the second base station and the mobility information of the terminal,
generate a signal for connecting to the second base station based on a result of the determination, and
after connecting to the second base station, determine whether the terminal is to be located outside the coverage of the second base station based on the location information of the second base station and the mobility information of the terminal.
8. The terminal of claim 7 , wherein the at least one message further includes at least one of a public land mobile network (PLMN) identifier of the second base station, and coverage information of the second base station.
9. The terminal of claim 7 ,
wherein the at least one message further includes information associated with a signal strength of the second base station, and
wherein, to determine whether the terminal is to be located within the coverage of the second base station, the controller is configured to generate a database for a quality of the second RAT based on the information associated with the signal strength of the second base station.
10. The terminal of claim 7 , wherein the controller is further configured to:
identify a number of the at least one message received from the first base station, in case that the terminal is connected to the second base station, and
determine whether to maintain a connection to the second base station, based on the number of the at least one message received from the first base station.
11. The terminal of claim 7 , wherein the controller is further configured to display a screen to notify that the second RAT is to be terminated, based on a result of the determination that the terminal is to be located outside the coverage of the second base station.
12. The terminal of claim 7 , wherein the controller is further configured to determine to connect to the first base station based on a result of the determination that the terminal is to be located outside the coverage of the second base station.
