Abstract

A method and system for providing multi-user shared access to service applications operating in wireless data services such as Wireless Application Protocol (WAP) is described. An exemplary embodiment of the present invention comprises a solution that provides a modified communication pathway that permits mobile clients to join an active session engaged by other clients. The system comprises a gateway 200 and a coordinating browser 206 (co-browser) which cooperates with the gateway subsystem 202 and the WAP subsystem 204 to coordinate and establish shared sessions between users. When a first client 220 is engaged in an active session, the co-browser 206 determines that a second client 230 wishes to join the session by analyzing the request containing the universal resource identifier (URI) transmitted by the second client. The co-browser enables all peer clients to interact, share, and view updated content within the application.

Claims

1. In a wireless telecommunication system for providing data services to a plurality of mobile clients, wherein said system comprises a gateway and a cooperating coordinating browser, a method of establishing a shared session within a service application in the wireless telecommunication system comprising the steps of:

establishing an active session with a first client;

receiving a request from a second client, wherein the second client requesting to join the active session;

analysing said request from the second client by the coordinating browser;

joining the second client into the active session with the first client and delivering the current context of the active session to the second client; and

delivering updated context to the first client and the second client thereby establishing an interactive shared session,

wherein said analysing step further comprises the coordinating browser determining the engagement status of the application such that when the application requested by the second client is not engaged, a connection with the application is performed in accordance with normal wireless access protocol (WAP) procedures.

2. A method according to claim 1 wherein said data services operate in accordance with Wireless Application Protocol (WAP).

3. A method according to claim 1 wherein said receiving step further includes receiving a join invocation at the second client from the gateway.

4. A method according to claim 1 wherein said analyzing step comprises the coordinating browser analyzing a universal resource identifier (URI) transmitted with the join request.

5. A method according to claim 2 wherein said data services are hosted on a service associated with the gateway.

6. A wireless telecommunication system for providing data services residing on host servers to a plurality of mobile clients, wherein the wireless telecommunication system comprises a gateway for having wireless communication with said mobile clients, characterised in that

the system comprises a coordinating browser functioning together with said gateway, wherein the browser being configured for establishing a shared session between at least two of said mobile clients for use in interacting within a service application, and wherein updated context by any mobile client can be delivered to all mobile clients in the shared session,

wherein coordinating browser is further configured to determine the engagement status of the application such that when the application requested by one of the at least two mobile clients is not engaged, a connection with the application is performed in accordance with normal wireless access protocol (WAP) procedures.

7. A system according to claim 6 characterised in that the data services operate in accordance with the wireless access protocol (WAP).

8. A system according to claim 7 characterised in that the gateway is a WAP gateway server for hosting WAP content and providing WAP-based service applications.

9. A system according to claim 7 characterised in that the coordinating browser is a software-based function residing in the gateway.

10. A system according to claim 7 characterised in that the context viewed by the mobile clients is in Wireless Markup Language (WML) format.

11. A computer readable storage medium having a stored computer program product comprising:

computer executable instructions for causing a wireless telecommunication gateway to provide wireless data services to a plurality of mobile clients; and

computer executable instructions for causing said gateway to operate together with a coordinating browser to establish a shared session between at least two of said mobile clients within a service application, and wherein updated context by any mobile client can be delivered to all mobile clients in the shared session; and

computer executable instructions for determining the engagement status of the application such that when the application requested by a mobile client is not engaged, a connection with the application is performed in accordance with normal wireless access protocol (WAP) procedures.

12. A wireless gateway operating in a wireless telecommunication system in order to provide wireless data services to a plurality of mobile clients, characterised in that

the gateway comprises a coordinating browser which cooperates to establish a shared session between at least two mobile clients within a wireless service application, and wherein updated context by any mobile client can be delivered to all mobile clients in the shared session,

wherein coordinating browser is further configured to determine the engagement status of the application such that when the application requested by one of the at least two mobile clients is not engaged, a connection with the application is performed in accordance with normal wireless access protocol (WAP) procedures.

13. A wireless gateway according to claim 12 characterised in that the gateway functionality is implemented on a computer server.
