Method of creating and managing session between wireless universal serial bus host and wireless universal serial bus device and providing wireless universal serial bus host and wireless universal serial bus device
First Claim
1. A session management method of managing a session created between a wireless Universal Serial Bus (USB) host and a wireless USB device through a wireless network, the session management method comprising:
- receiving session status messages periodically to check a status of the created session, wherein the session status messages indicate whether the created session is active;
changing a current status of the created session from a connected status to a suspended status if the current status of the created session is the connected status when a number of continuous reception failures corresponding to a number of the session status messages that are not received reaches a first reference number; and
terminating the created session if the current status of the created session is the suspended status when the number of the continuous reception failures reaches a second reference number,wherein the created session is a wireless USB session;
wherein the session status messages are received periodically to check the status during the entire created session; and
wherein the suspended status allows a session to be restarted without creating a new session.

Abstract
Provided is a session management method of managing a session created between a wireless universal serial bus (USB) host and a wireless USB device through a wireless network, the session management method including: receiving session status messages periodically transmitted for checking a status of the created session; counting a number of continuous reception failures representing a number of the session status messages that are not received; and if the number of the continuous reception failures of session status messages is greater than a reference number, changing the current status of the session to a suspended status if the current status of the session is a connected status, and closing the created session if the current status of the session is a suspended status.

17. A wireless USB host for managing a session created with a wireless USB device through a wireless network, the wireless USB host comprising:
-
a message generating unit to generate a session status message for checking a status of the created session, wherein the session status message generated by the message generating unit indicates whether the created session is active; a wireless transceiving unit to periodically transmit the generated session status message to the wireless USB device through the wireless network and to receive a session status message from the wireless USB device through the wireless network, wherein the session status message received from the wireless USB device indicates whether the created session is active; a counter to count a number of continuous reception failures corresponding to a number of the session status messages that are not received from the wireless USB device; and a session creation management unit to change a current status of the created session from a connected status to a suspended status if the current status of the created session is the connected status when the number of the continuous reception failures reaches a first reference number, and to terminate the created session if the current status is the suspended status when the number of the continuous reception failures reaches a second reference number, wherein the generated session status message is periodically transmitted to check the status during the entire created session; and wherein the suspended status allows a session to be restarted without creating a new session. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A wireless USB device for managing a session created with a wireless USB host through a wireless network, the wireless USB device comprising:
-
a wireless transceiving unit to receive through the wireless network a session status message, periodically transmitted from the wireless USB host through the wireless network, indicating a status of the created session, wherein the session status message indicates whether the created session is active; a counter to count a number of continuous reception failures corresponding to a number of the session status messages that are not received from the wireless USB host; and a session creation management unit to change a current status of the created session from a connected status to a suspended status if the current status of the created session is the connected status when the number of the continuous reception failures is greater than a first reference number, and to close the created session if the current status is the suspended status when the number of the continuous reception failures is greater than a second reference number, wherein the session status message is periodically transmitted to indicate the status during the entire created session; and wherein the suspended status allows a session to be restarted without creating a new session. - View Dependent Claims (31, 32, 33, 34)
