Method and device for service negotiation
First Claim
1. A method of service negotiation by a first device, the method comprising:
- detecting a second device using a first protocol;
transmitting, to the second device using the first protocol, a message comprising first indication information indicating that the first device seeks to use a first service and second indication information indicating that the first device provides a second service, the first service and the second service to be executed using a second protocol;
identifying, whether a first selection message or a second selection message is received from the second device using the first protocol, wherein the first selection message comprises indication information indicating that the first service is supported by the second device, and wherein the second selection message comprises indication information indicating that the first service is not supported and indication information requesting the second service;
establishing a connection with the second device using the second protocol for executing the first service or the second service, when the first selection message or the second selection message is received from the second device using the first protocol; and
executing the first service with the second device when the first selection message is received, or the second service with the second device when the second selection message is received, based on the connection using the second protocol.

Abstract
A method and an electronic device for service negotiation are provided. The method includes sensing, by the electronic device, a counterpart device through a first protocol, transmitting a request message to the counterpart device through the first protocol, the request message including indication information indicating that the electronic device requests a first service and first service information regarding the first service, and connecting with the counterpart device through a second protocol, when a selection message including indication information selecting the first service is received from the counterpart device through the first protocol, and, after connecting through the second protocol, executing the first service with the counterpart device using the first service information. The request message and the selection message each includes connection information for a connection using the second protocol, and the electronic device and the counterpart device use the connection information to perform the connection using the second protocol.

6. A method of service negotiation by a second device, the method comprising:
-
detecting a first device using a first protocol; receiving from the first device using the first protocol when the second device is tagged with a tag attached to the first device, a message comprising at least one of first indication information indicating that the first device seeks to use a first service and second indication information indicating that the first device provides a second service, the first service and the second service to be executed using a second protocol; establishing a connection with the first device using the second protocol, when service execution is determined based on the first indication information and the second indication information in the message; determining one service of the first service and the second service which is selected by the second device from services that are provided by the first device; and executing the determined service based on the connection using the second protocol. - View Dependent Claims (7, 8)

9. A first device of service negotiation, the first device comprising:
-
a communication device configured to; detect a second device using a first protocol, transmit, to the second device using the first protocol, a message comprising first indication information indicating that the first device seeks to use the first service and second indication information indicating that the first device provides a second service, and a second protocol being used for executing the first service and the second service; and at least one processor configured to; identify, whether a first selection message or a second selection message is received from the second device using the first protocol, wherein the first selection message comprising indication information indicating that the first service is selected by the second device, and wherein the second selection message comprises indication information indicating that the first service is not supported and indication information requesting the second service, establish a connection with the second device using the second protocol for executing the first service or the second service, when the first selection message or the second selection message is received from the second device using the first protocol, and execute the first service with the second device when the first selection message is received, or the second service with the second device when the second selection message is received, based on the connection using the second protocol. - View Dependent Claims (10, 11, 12, 13)

14. A second device of service negotiation, the second device comprising:
-
a communication device configured to; detect a first device using a first protocol, and receive a message from the first device using the first protocol when the second device is tagged with a tag attached to the first device, the message comprising at least one of first indication information indicating that the first device seeks to use a first service and second indication information indicating that the first device provides a second service, the first service and the second service to be executed using a second protocol; and at least one processor configured to; establish a connection with the first device using the second protocol, when service execution is determined based on the first indication information and the second indication information in the message, determine one service of the first service and the second service which is selected by the second device from services that are provided by the first device, and execute the determined service based on the connection using the second protocol. - View Dependent Claims (15, 16, 17)
