Use of wireless circuit-switched connections for transferring information requiring real-time operation of packet-switched multimedia services
First Claim
1. A method of operation in a multi bearer service gateway network device to provide communications between a mobile radio terminal and a multimedia core network via a wireless access network, the method comprising:
- receiving by the multi bearer service gateway network device a location updating request transmitted by the mobile radio terminal via the wireless access network;
generating by the multi bearer service gateway network device a session initiation protocol (SIP) registration request in response to the received location updating request,setting a FROM header field of the SIP registration request to an address connection connected to a SIP session services of a SIP end point of the mobile radio terminal; and
storing the SIP registration to a nontransitory memory of the multi bearer service gateway network device.

Abstract
A system includes a terminal, a wireless access network, a multimedia core network and a network device, which connects the wireless access network to the multimedia core network, expanded location updating to the registration procedure of the multimedia core network, and performs double registration of the user to the multimedia core network. The terminal performs expanded location updating relaying the registration point identity of the multimedia core network, the user'"'"'s phone number and the private user identity to the network device in connection with normal location updating signaling. In the double registration performed by the network device, two addresses are registered for the user of the terminal, one of which is associated with the domain name of the terminal in question or a numeric IP address, and the other to a domain name of the network device or a numeric IP address.

20. A multi bearer service gateway network device to provide communications between a mobile radio terminal and a multimedia core network via a wireless access network, the multi bearer service gateway network device comprising:
-
a number of communications interfaces; a nontransitory memory; a controller communicatively coupled to the communications interfaces and the nontransitory memory, and which upon receipt of a location updating request transmitted by the mobile radio terminal via the wireless access network; generates a session initiation protocol (SIP) registration request in response to the received location updating request, wherein the controller sets a FROM header field of the SIP registration request to an address connection connected to a SIP session services of a SIP end point of the mobile radio terminal; and stores the SIP registration request to the nontransitory memory of the multi bearer service gateway network device. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
