Abstract

A method and a device are provided. The device includes an antenna module, an interface for delivery to a protocol for transmission, a memory, and a processor, wherein the processor is set to determine antenna information for each beam index based on a transmission beam that can be generated in the antenna module, generate beam book information based on the determined antenna information, and transmit the beam book information and device connection information, related to an electronic device present inside the coverage of a base station, to an external server through the interface.

First claim

What is claimed is:

1. A base station comprising:
an antenna module;
an interface configured to perform delivery to a protocol for transmission;
a memory; and
a processor,
wherein the processor is configured to:
determine antenna information for each beam index based on a transmission beam producible by the antenna module,
produce beam book information based on the determined antenna information,
map the beam book information to a beam area,
store the mapped beam book information in the memory,
transmit the beam book information to an external server via the interface,
perform beamforming based on the beam book information,
identify an electronic device by receiving a reception beam from the electronic device in response to a transmission beam transmitted by the beamforming based on the beam book information, and
transmit device connection information including information associated with the identified electronic device to the external server.

2. The base station of claim 1 , wherein the processor is further configured to:
assign the beam index based on an angle or intensity of an antenna element included in the antenna module, and
produce the beam book information including antenna information corresponding to the assigned beam index.

3. The base station of claim 1 , wherein the device connection information is configured to include at least one of an identifier of the electronic device, beam information of the electronic device, beam movement information of the electronic device, radio resource information of the electronic device, a number of electronic devices in a beam area, or an order of entry of electronic devices in a beam area.

4. The base station of claim 1 , wherein the processor is further configured to transmit the device connection information to the external server if at least one case is satisfied among a case in which a new electronic device enters a beam area associated with a coverage area of the base station, a case in which the electronic device leaves the beam area, and a case in which beam information of the electronic device is changed.

5. The base station of claim 1 , wherein the processor is further configured to transmit the beam book information to the external server if a request for transmission of beam book information is received from the external server.

6. A server comprising:
a memory; and
a processor,
wherein the processor is configured to:
receive at least one piece of beam book information from a base station,
map the beam book information to a beam geographical area,
store the mapped beam book information in the memory,
produce a service table based on the mapped beam book information, wherein the service table is produced by mapping an area-based service set by a service application to the beam book information,
receive device connection information from the base station, and
provide an area-based service to an electronic device based on the device connection information and the service table.

7. The server of claim 6 , wherein the processor is further configured to receive a plurality of pieces of beam book information from a plurality of base stations connected to the server.

8. The server of claim 7 , wherein the processor is further configured to assign a single piece of beam information included in the at least one piece of beam book information to a single beam area or to group a plurality of pieces of beam information included in the at least one piece of beam book information so as to assign the same to a single beam area.

9. The server of claim 8 , wherein the processor is further configured to set the beam geographical area based on service information.

10. The server of claim 6 , wherein the processor is further configured to:
request transmission of the beam book information from the base station, and
receive the beam book information from the base station that provides a response to the request.

11. The server of claim 10 , wherein the processor is further configured to transmit, to a content server, at least one of beam book information, a service table, or device connection information stored in the memory, in response to a request for information from the content server.
