Proxy communication system and proxy communication system controlling method in BAN environment
Disclosed is a method of controlling a communication system including one or more sensors attached to a user, a wireless communication apparatus, and a coordinator. The method of controlling the communication system includes receiving a request for a proxy authority for a proxy between the one or more sensors and the coordinator from the wireless communication apparatus and assigning the proxy authority to the wireless communication apparatus by the coordinator; generating a user identifier corresponding to the user by the wireless communication apparatus; searching for the one or more sensors attached to the user and establishing pairings with the found one or more sensors by the wireless communication apparatus; making a request for association information for an association between the coordinator and the sensors from the found one or more sensors and receiving the association information by the wireless communication apparatus; making a request for an association proxy for an association between the found one or more sensors and the coordinator from the coordinator and receiving the association proxy in response to the request by the wireless communication apparatus; and establishing an association with the found one or more sensors, making a request for data, and receiving the data in response to the request for the data by the coordinator.
1. A method of controlling one or more sensors and a coordinator by a wireless communication apparatus, the method comprising:
transmitting a request for a proxy authority to a coordinator;
receiving the proxy authority from the coordinator, in response to the request for proxy authority;
identifying a user identifier, based on the received proxy authority;
searching for one or more sensors based on the received proxy authority;
establishing one or more pairings with the searched one or more sensors;
transmitting, to the searched one or more sensors, a request for association information for associating at least one sensor among the searched one or more sensors with the coordinator;
receiving the association information, in response to the request of association information;
transmitting, to the coordinator, a request for a group association proxy for associating the searched one or more sensors with the coordinator, based on the identified user identifier; and
receiving the group association proxy, in response to the request of group association proxy.
2. The method as claimed in claim 1 , further comprising transmitting the user identifier to the searched one or more sensors after receiving the association information.
3. The method as claimed in claim 1 , wherein the identifying of the user identifier comprises identifying the user identifier based on an external input for the user identifier.
4. The method as claimed in claim 1 , wherein the identifying of the user identifier comprises identifying the user identifier based on an RF signal received from an RF signal identifying means located in surroundings of the user.
5. The method as claimed in claim 1 , wherein the establishing of the one or more pairings comprises establishing the one or more pairings based on a near field communication (NFC) scheme.
6. The method as claimed in claim 1 , wherein the establishing of the one or more pairings comprises sequentially establishing the one or more pairings with the searched one or more sensors when communication schemes used by the searched one or more sensors are equal.
7. The method as claimed in claim 1 , wherein the association information contains at least one of an identifier of the searched one or more sensor and information on the searched one or more sensor.
8. The method as claimed in claim 7 , wherein the information on the sensor is at least one of a serial number of the searched one or more sensor, a type of the searched one or more sensor, and a battery type.
9. The method as claimed in claim 7 , wherein, when the coordinator includes a database for the information on the searched one or more sensor, the association information contains the identifier of the searched one or more sensor.
10. The method as claimed in claim 7 , wherein, when the coordinator does not include a database for the information on the searched one or more sensor, after receiving the request for the association proxy comprises building an identifier list database of the searched one or more sensor based on the user identifier by the coordinator.
11. The method as claimed in claim 1 , wherein the establishing of the one or more pairings comprises establishing the one or more pairings only with some of the searched one or more sensors.
12. The method as claimed in claim 11 , wherein the some of the searched one or more sensors are selected based on an external input signal.
13. The method as claimed in claim 11 , wherein the some of the searched one or more sensors are selected based on an intensity of a signal received from the searched one or more sensors.
14. The method as claimed in claim 1 , wherein the association proxy contains one or more of an identifier of the wireless communication apparatus, the user identifier, and information on each of the searched one or more sensors.
15. The method as claimed in claim 1 , wherein the transmitting of the request for the proxy authority comprises transmitting an identifier of the wireless communication apparatus as well by the wireless communication apparatus.
16. The method as claimed in claim 1 , further comprising:
establishing, by the coordinator, one or more associations with the searched one or more sensors using the group association proxy, by the coordinator;
transmitting, by the coordinator, one or more requests for data to the searched one or more sensors; and
receiving, by the coordinator, the data in response to the request for the data.
17. The method as claimed in claim 1 , wherein the identifying of the user identifier comprises identifying the user identifier based on one of the received proxy authority or identified information via a wireless communication.
18. The method as claimed in claim 17 , wherein the identifying of the user identifier comprises identifying the user identifier based on a radio-frequency identification (RFID) tag.
