Abstract

A method and system for initiating a subsequent connection is provided. The method includes sending by a first device a connection request including bootstrap information from the first device to establish an initial connection with a second device, wherein the bootstrap information comprises at least one of channel information, a power profile associated with the second device, and a role; and initiating by the first device the subsequent connection with the second device after receiving a successful connection response including bootstrap information from the second device.

First claim

What is claimed is:

1 . A method of initiating a subsequent connection implemented in a device, the method comprising:
sending, by a first device, a connection request including bootstrap information from the first device to establish an initial connection with a second device, wherein the bootstrap information comprises at least one of channel information, a power profile associated with the second device, and a role; and initiating, by the first device, the subsequent connection with the second device, after receiving a successful connection response including bootstrap information from the second device.

2 . The method of claim 1 , wherein initiating, the subsequent connection with the second device, comprises:
storing the bootstrap information from the second device received in the successful connection response; terminating the initial connection with the second device; and initiating, by the first device, the subsequent connection with the second device after terminating the initial connection with the second device.

3 . The method of claim 1 , further comprises:
establishing the subsequent connection, by the first device, with the second device, based on the bootstrap information from the second device received in the successful connection response during the initial connection.

4 . The method of claim 3 , wherein establishing the subsequent connection by the first device with the second device comprises:
sending a discovery request, by the first device, to the second device, using channel information received during the initial connection with the second device, wherein the discovery request is sent by considering a power profile associated with the second device; receiving a discovery response, by the first device, from the second device, including a role of the second device in the bootstrap information of the second device; initiating the subsequent connection, by the first device, with the second device, by sending a provision discovery request using the channel information; and establishing the subsequent connection, by the first device, with the second device, in response to receiving a provision discovery response to the provision discovery request.

5 . The method of claim 3 , wherein establishing the subsequent connection comprises:
sending a subsequent connection request, by the first device, to the second device, using the channel information received during the initial connection with the second device; triggering a persistent group created during the initial connection; receiving a successful subsequent connection response, by the first device, from the second device; and establishing the subsequent connection, by the first device, with the second device, by participating in the persistent group, based on the role of the first device.

6 . The method of claim 3 , wherein establishing the subsequent connection comprises:
sending a subsequent connection request to initiate an association process, by the first device, to the second device, based on the channel information, an Autonomous Group Owner (AutoGO) information, the role, an Internet Protocol (IP) address sent in the bootstrap information of the first device during the initial connection, wherein the channel information is an operating channel and the role is a Group Owner (GO) role; receiving a successful subsequent connection response, by the first device, from the second device, to the subsequent connection request; and establishing the subsequent connection, by the first device, with the second device, based on the AutoGO information received in the bootstrap information during the initial connection.

7 . A system for initiating a subsequent connection, comprising:
a first device configured to: send a connection request including bootstrap information of the first device to establish an initial connection with a second device, wherein the bootstrap information comprises at least one of channel information, a power profile associated with the second device, and a role, wherein the second device is configured to: send a successful connection response including bootstrap information of the second device to the first device in response to receiving the connection request, wherein the first device is further configured to initiate the subsequent connection with the second device after receiving the successful connection response.

8 . The system of claim 7 , wherein initiating, by the first device, the subsequent connection with the second device after receiving the successful connection response comprises:
storing the bootstrap information of the second device received in the successful connection response; terminating the initial connection with the second device; and initiating, by the first device, the subsequent connection with the second device after terminating the initial connection with the second device.

9 . The system of claim 7 , wherein the first device is further configured to:
establish the subsequent connection with the second device, based on the bootstrap information of the second device received in the successful connection response during the initial connection.

10 . The system of claim 9 , wherein the first device is further configured to:
send a discovery request to the second device, using channel information received from the second device during the initial connection with the second device, wherein the discovery request is sent by considering the power profile associated with the second device, and receive a discovery response from the second device, including a role of the second device in the bootstrap information of the second device; initiate the subsequent connection with the second device, by sending a provision discovery request using the channel information received from the second device; and establish the subsequent connection with the second device, in response to receiving a provision discovery response to the provision discovery request.

11 . The system of claim 9 , wherein the first device is further configured to:
send a subsequent connection request to the second device, using the channel information received during the initial connection with the second device; trigger a persistent group created during the initial connection; receive a successful subsequent connection response from the second device; and establish the subsequent connection with the second device, by participating in the persistent group based on the role of the first device.

12 . The system of claim 9 , wherein the first device is further configured to:
send a subsequent connection request to initiate an association process to the second device, based on the channel information received from the second device, an Autonomous Group Owner (AutoGO) information, the role, an Internet Protocol (IP) address sent in the bootstrap information during the initial connection, wherein the channel information received from the second device is an operating channel and the role is a Group Owner (GO); receive a successful subsequent connection response, from the second device, to the subsequent connection request; and establish the subsequent connection with the second device, based on the AutoGO information received in the bootstrap information during the initial connection.

13 . A device for initiating a subsequent connection, the device configured to:
send a connection request including bootstrap information to establish an initial connection with another device, wherein the bootstrap information comprises at least one of channel information, a power profile associated with the another device, and a role; rec
