"A MEDIA GATEWAY FOR INTERCONNECTING TWO OR MORE MOBILE ACCESS NETWORKS"

Abstract

A telecommunications system and method is disclosed for using H.248 Media Gateways within Access Networks of third-generation mobile systems. Each H.248 Access Network Media Gateway is capable of serving one or more radio servers of an Access Network, and one or more network servers of the Core Network. In addition, pools of devices (e.g., transcoders) can be shared between the radio servers and network servers. Furthermore, the Media Gateways within the Access Network can provide H.248 Virtual Gateways capable of serving the radio servers within two or more Access Networks and the network servers within the Core Network.

We Claim: 1. A media gateway (200) for interconnecting two or more mobile access networks (150a, 150b), comprising: a first virtual media gateway (210a) associated with a first one (150a) of said two or more mobile access networks, said first virtual media gateway (210a) having an H.248 interface to a radio server (20a) within said first mobile access network (150a) for handling the user traffic control and a physical connection to at least one base station (25a) within said first access network (150a) for handling the call connectivity to and from said first access network (150a); a second virtual media gateway (210b) associated with a second one (150b) of said two or more mobile access networks, said second virtual media gateway (210b) having an H.248 interface to a radio server (20b) within said second mobile access network (150b) for handling the user traffic control and a physical connection to at least one base station (25b) within said second access network (150b) for handling the call connectivity to and from said second access network (150b); and a third virtual media gateway (210c-e) having an H.248 interface to at least one core network server (14, 15, 16) within a core network (120) for handling the connectivity control between said two or more mobile access networks (150a, 150b) and said core network (120), said first (210a) and second (210b) virtual media gateways being interconnected via said third virtual media gateway (210c-e). 2. The media gateway as claimed in claim 1, wherein each of said virtual media gateways has a connection handler therein capable of establishing a connection between said first virtual media gateway and said second virtual media gateway via said third virtual media gateway in order to convert payloads between said virtual media gateways for a call. 3. The media gateway as claimed in claim 2, further comprising: a database housing resource components, said virtual media gateways being capable of sharing said resource components within said database. 4. The media gateway as claimed in claim 3, wherein said connection handlers are further capable of allocating available ones of said resource components from said database for said call. 5. The media gateway as claimed in claim 3, wherein said resource components comprise one or more transcoders. 6. The media gateway as claimed in claim 3, wherein said resource components comprise payload framing components and payload stream components. 7. The media gateway as claimed in claim 3, wherein at least one of said two or more access networks maintains separate resource components within said database for use by said respective first or second virtual media gateway. 8. The media gateway as claimed in claim 1, wherein one of said two or more access networks is a Universal Terrestrial Radio Access Network. 9. The media gateway as claimed in claim 1, wherein one of said two or more access networks is a Global System for Mobile Communications Network. 10. A method for establishing a call connection between a first mobile access network (150a) and a second mobile access network (150b) interconnected via a media gateway as claimed in claim 1, comprising: receiving a message at a network server (14, 15, 16) within a core network (120) to setup said call connection; establishing a logical connection between a first virtual media gateway (210a) associated with said first mobile access network (150a) and a second virtual media gateway (210b) controlled by said network server (14, 15, 16); establishing a logical connection between said second virtual media gateway (210b) and a third virtual media gateway (210c-e) associated with said second mobile access network (150b); allocating resource components from a database (50) within said media gateway (200) for said call connection; and establishing a physical connection between a base station (25 a) of said first mobile access network (150a) and said first virtual media gateway (210a) and between said third virtual media gateway (210c-e) and a base station (25b) of said second mobile access network (150b) for transmission of payloads during said call connection. 11. The method as claimed in claim 10, wherein said step of establishing a connection between said first and second virtual media gateways comprises: reserving a connection point in said second virtual media gateway associated with said first virtual media gateway. 12. The method as claimed in claim 11, wherein said step of establishing a connection between said second and third virtual media gateways comprises: reserving a connection point in said second virtual media gateway associated with said third virtual media gateway. 13. The method as claimed in claim 10, wherein said step of allocating said resource components further comprises: sharing said resource components between said virtual media gateways. 14. The method as claimed in claim 10, wherein said step of allocating said resource components further comprises: allocating separate ones of said resource components for said first and third virtual media gateways. 15. A third-generation mobile telecommunications system, comprising: a radio server within an access network of said third-generation telecommunications system for providing call control of calls within said access network; and a media gateway as claimed in claim 1 for providing connectivity of calls within said access network, said media gateway having an H.248 interface to said radio server for handling the user traffic control and a physical connection to at least one base station within said access networks for handling the call connectivity to and from said Access Network.
