Abstract

Examples of systems and methods are provided for communication and for facilitating establishing a remote session between a client device and a remote server. The system may facilitate establishing a trusted relationship between the client device and a host device. The system may be configured to receive login information from the host device for a first remote session established between the host device and the remote server. The system may facilitate continuing the first remote session previously established between the host device and the remote server as a continued remote session between the client device and the remote server.

Claims

1. A system at a client device side for communication and for transferring a remote session between a host device and a remote server to the client device, the system comprising:

a trusted relationship module of the client device configured to facilitate establishing a trusted relationship between the client device and a host device;

a login information receiver module of the client device configured to receive login information from the host device for a first remote session established between the host device and the remote server, the host device being an end point of the first remote session, the first remote session including the host device accessing at least one application running on the remote server;

a session launch module of the client device configured to use the login information received from the host device to facilitate continuing the first remote session previously established between the host device and the remote server as a continued remote session between the client device and the remote server;

a remote view module of the client device configured to receive display data from the remote server and display a remote desktop; and

a remote session termination module of the client device configured to send an indication to the host device that the client device continued the first remote session with the remote server.

2. The system of claim 1, wherein the trusted relationship module of the client device comprises:

a presence sensing module of the client device configured to sense presence of the host device near the client device;

a pairing module of the client device configured to perform a message exchange to pair the client device with the host device; and

a link security module of the client device configured to perform exchange of encryption information with the host device.

10. The system of claim 1, wherein the client session launch module is configured to continue the remote session previously established between the host device and the remote server as the continued remote session between the client device and the remote server based on a state of the remote session stored on the remote server.

3. A method at a client device side for communication and for transferring a remote session between a host device and a remote server to the client device, the method comprising:

establishing, by a trusted relationship module of the client device, a trusted relationship between the client device and a host device;

receiving at the client device login information from the host device for a first remote session established between the host device and the remote server, the host device being an end point of the first remote session, the first remote session including the host device accessing at least one application running on the remote server;

continuing the first remote session previously established between the host device and the remote server as a continued remote session between the client device and the remote server at least by using the login information received from the host device;

receiving display data at the client device from the remote server and displaying a remote desktop; and

sending from the client device to the host device an indication that the client device continued the first remote session with the remote server.

4. A non-transitory machine-readable medium encoded with instructions for execution at a client device side for communication and for transferring a remote session between a host device and a remote server to the client device, the instructions comprising code for:

establishing, by a trusted relationship module of the client device, a trusted relationship between the client device and a host device;

receiving at the client device login information from the host device for a first remote session established between the host device and the remote server, the host device being an end point of the first remote session, the first remote session including the host device accessing at least one application running on the remote server;

continuing the first remote session previously established between the host device and the remote server as a continued remote session between the client device and the remote server at least by using the login information received from the host device;

receiving display data at the client device from the remote server and displaying a remote desktop; and

sending from the client device to the host device an indication that the client device continued the first remote session with the remote server.

5. The non-transitory machine-readable medium of claim 4, wherein the code for establishing the trusted relationship comprises code for:

sensing presence of the host device near the client device;

performing a message exchange to pair the client device with the host device; and

performing an exchange of encryption information with the host device.

6. The non-transitory machine-readable medium of claim 4, wherein the code for establishing the trusted relationship comprises responding to a query message from the host device.

7. The non-transitory machine-readable medium of claim 4, wherein the client device is configured to communicate with the host device over a wireless connection.

8. The non-transitory machine-readable medium of claim 5, wherein the code for sensing presence comprises code for estimating a received signal strength of a transmission received from the host device.

9. The non-transitory machine-readable medium of claim 5, wherein the code for sensing presence comprises code for calculating a round trip delay time for communication with the host device and code for determining the presence of the host device near the client device based on whether the round trip delay time is below a threshold value.
