Claims
- 1. A method for establishing a connection between a terminal of a first type and a core network node of a second type in a telecommunications network comprising an access network and a core network, the telecommunications network supporting a data protocol of the second type, wherein at least one of the types comprises support of a packet-switched protocol and a remaining type comprises support of a different packet-switched protocol or a circuit-switched protocol, the method comprising the steps of:
receiving, at the access network node, a first initiation signal from the terminal, and in response to the first initiation signal, opening a first connection for the terminal; and while the first connection is active, receiving, at the access network node, a second initiation signal, and in response to the second initiation signal, opening a second connection for the terminal; whereby the core network node of the second type switches a real-time connection to or from the terminal.
- 2. The method according to claim 1, wherein the access network comprises a radio network.
- 3. The method according to claim 2, wherein the core network node comprises a mobile services switching center.
- 4. The method according to claim 1, wherein the first initiation signal comprises an attach request from the terminal.
- 5. The method according to claim 1, wherein the second initiation signal comprises a request to establish a call to or from the terminal.
- 6. The method according to claim 1, wherein each of the first and second connections comprise a packet data context.
- 7. The method according to claim 6, wherein the first connection comprises a signaling context and the second connection comprises a real-time context.
- 8. The method according to claim 1, wherein the terminal of the first type is circuit-switched and the core network node of the second type is packet-switched.
- 9. The method according to claim 1, wherein the terminal of the first type is packet-switched and the core network node of the second type is circuit-switched.
- 10. The method according to claim 1, wherein the terminal of the first type and the core network node of the second type use different packet-switched protocols.
- 11. A method for establishing a connection between a terminal of a first type and a core network node of a second type in a telecommunications network comprising an access network and a core network, the telecommunications network supporting a data protocol of the second type, wherein at least one of the types comprises support of a packet-switched protocol and the remaining type comprises support of a different packet-switched protocol or a circuit-switched protocol, the method comprising the steps of:
receiving, at the access network node, a first initiation signal from a terminal of a first type, and in response to the first initiation signal, opening a first connection for the terminal; using the first connection to open a second connection for the terminal; and whereby the core network node of the second type switches a real-time connection to or from the terminal.
- 12. The method according to claim 11, wherein the access network comprises a radio network.
- 13. The method according to claim 12, wherein the core network node comprises a mobile services switching center.
- 14. The method according to claim 11, wherein the first initiation signal comprises an attach request from the terminal.
- 15. The method according to claim 11, wherein the second initiation signal comprises a request to establish a call to or from the terminal.
- 16. The method according to claim 11, wherein each of the first and second connections comprise a packet data context.
- 17. The method according to claim 16, wherein the first connection comprises a signaling context and the second connection comprises a real-time context.
- 18. An access network node for supporting a connection between a first terminal of a first type and a core network node of a second type in a telecommunications network comprising an access network and a core network, the telecommunications network supporting a data protocol of the second type,
wherein at least one of the first type and second type comprises support of a packet-switched protocol and the remaining type comprises support of a different packet-switched protocol or a circuit-switched protocol, and wherein the access network node comprises an emulator logic for emulating a network of the first type toward the first terminal and for emulating a terminal of the second type toward the core network node.
- 19. The access network node according to claim 18, wherein the emulator logic comprises a connection establishment logic for establishing a signaling connection for the second terminal in response to a first initiation signal from the first terminal via a first connection of the first type and for using the first connection to open a second real-time connection for the second terminal.
- 20. The access network node according to claim 18, wherein the access network node comprises a radio network controller.
- 21. The access network node for supporting a connection between a first terminal of a first type and a core network node of a second type in a telecommunications network comprising an access network and a core network, the telecommunications network supporting a data protocol of the second type,
wherein at least one of the first type and second type comprises support of a packet-switched protocol and the remaining type comprises support of a different packet-switched protocol or a circuit-switched protocol, and wherein the access network node comprises emulator logic means for emulating a network of the first type toward the first terminal and for emulating a second terminal of the second type toward the core network node.
- 22. An access network node according to claim 21, wherein the emulator logic means comprises connection establishment logic means for establishing a signaling connection for the second terminal in response to a first initiation signal from the first terminal via a first connection of the first type and for using the first connection to open a second connection as a real-time connection for the second terminal.
- 23. The access network node according to claim 21, wherein the access network node comprises a radio network controller.
