Abstract

A mobile application running in a mobile device may be coordinated or synchronized with a non-mobile application running in a non-mobile device. The mobile and non-mobile applications may be, for example, calendar applications. To permit the use of a session-oriented (connection-oriented) protocol stack when the transmission medium between the mobile and non-mobile devices is connectionless, the mobile device sends an initial communication to the non-mobile device. In response to receipt of the initial communication, a session identifier is generated. A first connection-oriented protocol frame is then formed that includes an initial response and the session identifier. The first connection-oriented protocol frame is embedded in a first connectionless protocol frame, and the first connectionless protocol frame is sent to the mobile device. Although the mobile device initiates the session, the session is controlled by the non-mobile device.

Claims

1. A method of coordinating a mobile application running in a mobile device with a non-mobile application running in a non-mobile device, the method comprising:

receiving an initial communication from the mobile device by the non-mobile device;

in response to receipt of the initial communication, generating a session identifier;

forming a first connection-oriented protocol frame that includes an initial response and the session identifier;

embedding the first connection-oriented protocol frame in a first connectionless protocol frame;

sending the first connectionless protocol frame to the mobile device, in the mobile device, forming a second connection-oriented protocol frame that includes an invitation to provide service and the session identifier;

embedding the second connection-oriented protocol frame in a second connectionless protocol frame;

sending the second connectionless protocol frame to the non-mobile device;

in the non-mobile device receiving the invitation to provide service and the session identifier and in response thereto forming a third connection-oriented protocol frame that includes a request for service and the session identifier;

embedding the third connection-oriented protocol frame in a third connectionless protocol frame;

sending the third connectionless protocol frame to the mobile device;

in the mobile device, forming a fourth connection-oriented protocol frame that includes a result, a second invitation to provide service and the session identifier;

embedding the fourth connection-oriented protocol frame in a fourth connectionless protocol frame;

sending the fourth connectionless protocol frame to the non-mobile device;

in the non-mobile device, receiving the result, the second invitation to provide service and the session identifier and in response thereto forming a fifth connection-oriented protocol frame that includes a disconnect command and the session identifier;

embedding the fifth connection-oriented protocol frame in a fifth connectionless protocol frame; and

sending the fifth connectionless protocol fine to the mobile device.

2. A method of coordinating a mobile application running in a mobile device with a non-mobile application running in a non-mobile device, the method comprising:

in the mobile device, forming a first connection-oriented protocol frame that includes an invitation to provide service and a session identifier;

embedding the first connection-oriented frame in a first connectionless protocol frame;

sending the first connectionless protocol frame to the non-mobile device;

in the non-mobile device, receiving the invitation to provide service and the session identifier and in response thereto forming a second connection-oriented protocol frame that includes a request for service and the session identifier;

embedding the second connection-oriented protocol frame in a second connectionless protocol frame;

sending the second connectionless protocol frame to the mobile device;

in the mobile device, forming a third connection-oriented protocol frame that includes a result, a second invitation to provide service and the session identifier;

embedding the third connection-oriented protocol frame in a third connectionless protocol frame;

sending the third connectionless protocol frame to the non-mobile device;

in the non-mobile device, receiving the result, the second invitation to provide service and the session identifier and in response thereto forming a fourth connection-oriented protocol frame that includes a disconnect command and the session identifier;

embedding the fourth connection-oriented protocol frame in a fourth connectionless protocol frame; and

sending the fourth connectionless protocol frame to the mobile device.

3. A system for coordinating a mobile application running in a mobile device with a non-mobile application running in a non-mobile device, the system comprising:
