Abstract

The present invention relates to a communication technique for convergence of IoT technology and a 5G communication system for supporting a higher data transfer rate beyond a 4G system, and a system therefor. Also, the present invention provides a method for determining a location of a base station, the method comprising the steps of: receiving, from a terminal, a first message including location information of the terminal; and determining location information of the base station on the basis of the received location information of the terminal.

First claim

The invention claimed is:

1. A method performed by a base station for determining a location in a mobile communication system, the method comprising:
transmitting, to each of a plurality of terminals, a request message including a location information request;
receiving, from the plurality of terminals, first messages including location information of each of the plurality of terminals corresponding to the request message;
determining a priority of each of the plurality of terminals based on a state of the first messages;
selecting a corresponding terminal to be used for determining location information of the base station based on the determined priority; and
determining the location information of the base station based on location information of the selected corresponding terminal.

2. The method of claim 1 , further comprising:
determining whether a state of the first message satisfies a preset criterion; and
transmitting, to the terminal, a second message for adjusting a location of the terminal, in case that the state of the first message does not satisfy the preset criterion.

3. The method of claim 1 , further comprising:
transmitting, to an operator server, a third message including the determined location information of the base station; and
receiving, from the operator server, a fourth message including frequency band information determined based on the location information of the base station.

4. The method of claim 1 , further comprising:
determining whether the base station includes pre-stored location information of the base station;
determining whether the pre-stored location information is valid based on time information stored in the base station in case that the base station includes the pre-stored location information of the base station; and
determining the pre-stored location information as the location information of the base station in case that the pre-stored location information is valid.

5. The method of claim 1 , further comprising:
receiving, from a network server, a fifth message including time information or frequency information; and
performing synchronization based on the received time information or the received frequency information.

6. A base station in a mobile communication system, comprising:
a memory;
a transceiver configured to:
transmit, to each of a plurality of terminals, a request message including a location information request; and
receive, from each of the plurality of terminals, first messages including location information of the terminal corresponding to the request message; and

a controller operably connected to the memory and the transceiver, the controller configured to:
determine a priority of each of the plurality of terminals based on a state of the first messages;
select a corresponding terminal to be used for determining location information of the base station based on the determined priority; and
determine the location information of the base station based on location information of the selected corresponding terminal.

7. The base station of claim 6 , wherein the controller is further configured to:
determine whether a state of the first message satisfies a preset criterion, and
control the transceiver to transmit, to the terminal, in case that the state of the first message does not satisfy the preset criterion, a second message for adjusting a location of the terminal.

8. The base station of claim 6 , wherein the controller is further configured to control the transceiver to:
transmit, to an operator server, a third message including the determined location information of the base station; and
receive, from the operator server, a fourth message including frequency band information determined based on the location information of the base station.

9. The base station of claim 6 ,
wherein the controller is further configured to:
determine whether the base station includes pre-stored location information of the base station;
determine whether the pre-stored location information is valid based on time information stored in the base station in case that the base station includes the pre-stored location information of the base station; and
determine the pre-stored location information as the location information of the base station in case that the pre-stored location information is valid.

10. The base station of claim 9 , wherein the controller is further configured to:
identify whether the pre-stored location information of the base station is valid based on time information stored in the memory; and
store the determined pre-stored location information of the base station as the location information of the base station in the memory.
