Abstract

The present disclosure relates to a sensor network, machine type communication (MTC), machine-to-machine (M2M) communication, and technology for internet of things (IoT). The present disclosure may be applied to intelligent services based on the above technologies, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. An operating method of a first electronic device in a communication system is provided. The operating method includes detecting that a setup of a wireless connection with a second electronic device for a short range communication has been started; receiving, from the second electronic device, state information for determining a role of the first electronic device for the wireless connection; determining the role of the first electronic device based on the state information; completing the setup of the wireless connection based on the determined role; and communicating with the second electronic device through the wireless connection based on the determined role.

First claim

What is claimed is:

1. A method of a first device in a communication system, the method comprising:
detecting a second device to establish a wireless connection with the second device;
transmitting, to the second device, a confirmation message;
receiving, from the second device, service information of the second device during establishing the wireless connection;
determining a role of the first device as a host device based on the service information of the second device and a state of service context of the first device; and
communicating, based on the determined role as the host device, with the second device through the wireless connection,
wherein the service information includes at least one of information on another device connected to the second device or a role of the second device,
wherein the state of service context includes at least one of a type of a service provided by the first device or an application that is used by the first device, and
wherein the first device has two role stacks for providing a host role as the host device and a peripheral role as a connection device operated under a control of the host device.

2. The method of claim 1 , further comprising:
determining the role of the first device as the connection device for delivering data to a peripheral device connected to the first device, based on the first device supporting to store the data; and
communicating, based on the determined role as the connection device, with the second device through the wireless connection.

3. The method of claim 1 , further comprising:
determining the role of the first device as the connection device for delivering streaming data to a peripheral device connected to the first device based on the service information indicating that there is the streaming data to the peripheral device; and
communicating, based on the determined role as the connection device, with the second device through the wireless connection.

4. The method of claim 1 , further comprising:
determining the role of the first device as the connection device for delivering streaming data to a peripheral device connected to the first device and comprising a port function based on the first device supporting to play the streaming data; and
communicating, based on the determined role as the connection device, with the second device through the wireless connection.

5. The method of claim 1 , further comprising:
during maintaining the wireless connection, detecting whether the service information of the second device or connection ports of the first device for the wireless connection is changed;
determining a new role of the first device during establishing a new wireless connection; and
communicating, based on the determined new role, with the second device through the new wireless connection.

6. A method of a second device in a communication system, the method comprising:
transmitting a beacon signal to establish a wireless connection;
if a confirmation message is received from a first device in response to transmitting the beacon signal, transmitting, to the first device, service information of the second device;
receiving, from the first device, at least one of service information of the first device or connection information of the first device during establishing the wireless connection;
determining a role of the second device as a host device based on the service information of the first device and a state of service context of the second device; and
communicating, based on the determined role, with the second device through the wireless connection,
wherein the service information includes at least one of information on another device connected to the second device or a role of the second device, and
wherein the state of service context includes at least one of a type of a service provided by the first device or an application that is used by the first device, and
wherein the first device has two role stacks for providing a host role as the host device and a peripheral role as a connection device operated under a control of the host device.

7. The method of claim 6 , further comprising:
determining the role of the second device as the connection device for delivering data to a peripheral device connected to the second device based on the second device supporting to store the data; and
communicating, based on the determined role as the connection device, with the first device through the wireless connection.

8. The method of claim 6 , further comprising:
determining the role of the second device as the connection device delivering streaming data to a peripheral device connected to the second device based on the service information indicating that there is the streaming data to the peripheral device; and
communicating, based on the determined role as the connection device, with the first device through the wireless connection.

9. The method of claim 6 , wherein further comprising:
determining the role of the second device as the connection device for delivering streaming data to a peripheral device connected to the second device based on the second device supporting to play the streaming data; and
communicating, based on the determined role as the connection device, with the first device through the wireless connection.

10. The method of claim 6 , further comprising:
during maintaining the wireless connection, detecting whether the service information of the second device or connection ports of the first device for the wireless connection is changed;
determining a new role of the second device during establishing a new wireless connection; and
communicating, based on the determined new role, with the second device through the new wireless connection.

11. A first device in a communication system, the first device comprising:
a processor configured to
detect a second device to establish a wireless connection; and

a transceiver operably connected to the processor, the transceiver configured to transmit, to the second device, a confirmation message,
wherein:
the processor is further configured to determine a role of the first device as a host device based on service information of the second device and a state of service context of the first device; and
the transceiver is further configured to:
receive, from the second device, the service information of the second device during establishing the wireless connection; and
communicate, based on the determined role, with the second device through the wireless connection,

wherein the service information includes at least one of information on another device connected to the second device or a role of the second device,
wherein the state of service context includes at least one of a type of a service provided by the first device or an application that is used by the first device, and
wherein the first device has two role stacks for providing a host role as the host device and a peripheral role as a connection device operated under a control of the host device.

12. The first device of claim 11 , wherein the processor is further configured to:
determine the role of the first device as the connection device for delivering data to a peripheral device connected to the first device based on the second device supporting to store the data; and
control the transceiver to communicate, based on the determined role as the connection device, with the second device through the wireless connection.

13. The first device of claim 11 , wherein the processor is further configured to:
