Abstract
A method for establishing a connection between a circuit-switched mobile station (MS) and a packet-switched switching element (MSC). A radio network controller (RNC) receives a first initiation signal (an attach request) from the mobile station (MS) via a circuit-switched connection. The RNC opens a signaling connection for the mobile station. While the signaling connection is active, the RNC receives a second initiation signal (call setup) and opens a real-time connection for the mobile station. Thus the packet-switched switching element (MSC) is able to switch a real-time connection to/from the circuit-switched mobile station (MS).
Claims23
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.
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.
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.
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.
