Abstract
A method and node in a communication network for facilitating access by a client terminal to an IMS service from a non-Session Initiation Protocol (non-SIP) compliant access network such as a circuit-switched network. The node receives a request from the client terminal and in response, allocates to the terminal, a Terminal Adapter from a plurality of Terminal Adapters. The node then sends a message to the client terminal reporting the address of the allocated Terminal Adapter.
Claims16
A method in a node of a communication network of facilitating access by a client terminal to an IP Multimedia Subsystem (IMS) service from a non-Session Initiation Protocol compliant access network, the method comprising:
- receiving a request message from the client terminal, wherein the request message includes a terminal identifier or a requested service identifier;
- in response to receipt of said request message, allocating to the client terminal a Terminal Adapter from a plurality of Terminal Adapters based on the terminal identifier or the requested service identifier;
- and
- sending to the client terminal a message reporting the address of the allocated Terminal Adapter.
(canceled)
A method of routing a message between a client terminal and a Terminal Adapter, the Terminal Adapter providing an interface between a non-Session Initiation Protocol compliant network and an IP Multimedia Subsystem (IMS) network, the method comprising:
- sending from the client terminal, a message destined for an IMS Centralized Services node, said message containing an address of a selected Terminal Adapter;
- and
- sending the message from the IMS Centralized Services node to the Terminal Adapter at the Terminal Adapter address.
(canceled)
A node in a communications network for allocating a Terminal Adapter to a client terminal, the node comprising:
- means for receiving a request message sent from the client terminal, the request message including a terminal identifier or a requested service identifier;
- means for selecting a Terminal Adapter from a plurality of Terminal Adapters based on the terminal identifier or the requested service identifier;
- and
- means for sending a message to the client terminal, the message containing the address of the selected Terminal Adapter.
(canceled)
A Mobile services Switching Centre/Visitor Location Register node for use in a mobile communications network, the node comprising:
- means for receiving a message from a client terminal, said message containing an address of a Terminal Adapter;
- and
- means for sending forwarding the message to the addressed Terminal Adapter.
