2. The method of claim 1 , wherein at least some of the plurality of application server chat/VoIP clients at the application server are proprietary clients, and wherein the privileged chat/VoIP service application is a standardized service application that is non-proprietary.
3. The method of claim 2 , further comprising converting between proprietary protocols required by the plurality of application server chat/VoIP clients and a standardized protocol supported by the privileged chat/VoIP service application.
4. The method of claim 3 , wherein providing said protocol conversion comprises coordinating and mapping of chat/VoIP services, features and, functions to and from the UE chat/VoIP client.
5. The method of claim 1 , further comprising reading and representing at the mobile UE in a single Graphical User Interface (GUI) statuses from different application chat/VoIP clients.
6. The method of claim 1 , wherein the UE chat/VoIP client is an IP Multimedia Subsystem (IMS) based client, wherein the application server is a session initiation protocol (SIP) application server (SIP-AS) in an IMS core network, and wherein the privileged chat/VoIP service application is an IMS based application.
7. The method of claim 1 , wherein the UE chat/VoIP client is preinstalled on the mobile UE.
8. An application server for providing at least one of chat and Voice over Internet Protocol (chat/VoIP) services to a mobile User Equipment (UE) in a mobile telecommunications network, wherein the application server comprises communications equipment and processing equipment, wherein the processing equipment is configured to:
execute at the application server a privileged chat/VoIP service application to which the mobile telecommunications network guarantees quality of service;
execute a plurality of application server chat/VoIP clients at the application server that are configured to access a plurality of different chat/VoIP communication environments operated by a plurality of different chat/VoIP service providers; and
connect said privileged chat/VoIP service application to said UE chat/VoIP client, and connecting said chat/VoIP service application to one or more of the plurality of application server chat/VoIP clients at the application server, to thereby enable the same UE chat/VoIP client to access different chat/VoIP communication environments with guaranteed quality of service over the mobile telecommunications network.
9. The application server of claim 8 , wherein said processing equipment and said communications equipment are configured to support Session Initiation Protocol (SIP) signalling in an IP Multimedia Subsystem (IMS).
10. The application server of claim 8 , wherein at least some of the plurality of application server chat/VoIP clients at the application server are proprietary clients, and wherein the privileged chat/VoIP service application is a standardized service application that is non-proprietary.
11. The application server of claim 10 , wherein said processing equipment is configured to convert between proprietary protocols required by the plurality of application server chat/VoIP clients and a standardized protocol supported by the privileged chat/VoIP service application.
12. The application server of claim 11 , wherein said processing equipment is configured to provide said protocol conversion by coordinating and mapping of chat/VoIP services, features and, functions to and from the UE chat/VoIP client.
13. The application server of claim 8 , wherein said processing equipment is configured to read and represent at the mobile UE in a single Graphical User Interface (GUI) statuses from different application chat/VoIP clients.
14. The application server of claim 8 , wherein the UE chat/VoIP client is an IP Multimedia Subsystem (IMS) based client, wherein the application server is a session initiation protocol (SIP) application server (SIP-AS) in an IMS core network, and wherein the privileged chat/VoIP service application is an IMS based application.
15. The application server of claim 8 , wherein the UE chat/VoIP client is preinstalled on the mobile UE.
16. A mobile User Equipment (UE) configured to operate in a mobile telecommunications network, said mobile UE comprising input and output equipment, communications equipment, and processing equipment, wherein said processing equipment is configured to execute a UE chat/VoIP client and is further configured, via said input and output equipment, said communications equipment, and said UE chat/VoIP client, to:
access the chat/VoIP services of any given one of a plurality of different chat/VoIP communication environments by connecting the UE chat/VoIP client, via privileged use of said mobile telecommunications network, to a privileged chat/VoIP service application at an application server, wherein the mobile telecommunications network guarantees quality of service to the privileged chat/VoIP service application; and
represent Graphical User Interfaces of the plurality of different chat/VoIP communication environments.
17. The mobile UE of claim 16 , wherein at least some of the plurality of different chat/VoIP communication environments are proprietary, and wherein the privileged chat/VoIP service application is a standardized service application that is non-proprietary.
18. The mobile UE of claim 16 , wherein the UE chat/VoIP client is an IP Multimedia Subsystem (IMS) based client, wherein the application server is a session initiation protocol (SIP) application server (SIP-AS) in an IMS core network, and wherein the privileged chat/VoIP service application is an IMS based application.
19. The mobile UE of claim 16 , wherein the UE chat/VoIP client is preinstalled on the mobile UE.
