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.

Claims

1. A method for performing a double registration of a user of a terminal to a multimedia core network, the method comprising:

registering a first public identity and a second public identity for the user of the terminal,

registering, in a multi bearer service gateway, a fully unambiguous identity of the user as said first public identity, and

registering, in said multi bearer service gateway, for said first public identity an address combination according to a fully unambiguous domain name formed by said fully unambiguous identity of the user and the domain name or a numeric IP address of the multi bearer service gateway.

2. The method according to claim 1, further comprising:

registering, in said multi bearer service gateway, as said second public identity the address combination registered for said first identity, and

registering, in said multi bearer service gateway, for said second public identity an address combination according to a fully unambiguous domain name formed by said fully unambiguous identity of the user and the domain name or a numeric IP address of the multi bearer service gateway.

3. The method according to claim 1, further comprising registering, in the terminal, as said first public identity said fully unambiguous identity of the user and for said first public identity an address combination according to the domain name or a numeric IP address of the terminal.

4. The method according to claim 3, wherein the address combination registered by the terminal for said first public identity is privileged.

5. The method according to claim 1, further comprising establishing a double connection between the terminal and the multimedia service network such that the first connection is established with the first public identity and the second connection is established with the second public identity.

6. The method according to claim 5, wherein said first public identity includes a phone number and said second public identity includes said phone number.

7. The method according to claim 6, further comprising registering the address combination of said first public identity including said phone number in the multi bearer service gateway as privileged, if said phone number is also said first public identity registered by the terminal.

8. The method according to claim 5, further comprising:

specifying an address of a transfer end point of real-time information of the terminal in said multimedia core network by the multi bearer service gateway,

relaying said address of the transfer end point of real-time information from the multi bearer service gateway to the terminal in connection with a connection establishing procedure of said second connection,

specifying the address of the transfer end point of real time information of said transfer end point to be reached in said multimedia core network by said transfer end point to be reach or another multi bearer service gateway, and

relaying the address of the transfer end point of said real-time information of said transfer end point to be reached to the multi bearer service gateway in connection with the connection establishing procedure of said first connection.

9. A system for performing a double registration of a user of a terminal to a multimedia core network, the system comprising:

a wireless access network for providing access to the terminal, which includes a radio network of a public mobile phone system or a radio network utilizing unlicensed frequencies,

the multimedia core network including an IP multimedia subsystem, a generic IP voice and communication network, or a proprietary network,

a multi bearer service gateway comprising means for registering a first public identity and a second public identity for the user of the terminal, wherein the multi bearer service gateway is arranged to;

register a fully unambiguous identity of the user as said first public identity, and

register for said first public identity an address combination according to a fully unambiguous domain name formed by said fully unambiguous identity of the user and the domain name or a numeric IP address of the multi bearer service gateway.

10. The system according to claim 9, wherein the multi bearer service gateway is further arranged to:

register as said second public identity the address combination registered for said first identity, and

register for said second public identity an address combination according to a fully unambiguous domain name formed by said fully unambiguous identity of the user and the domain name or a numeric IP address of the multi bearer service gateway.

11. The system according to claim 9, wherein the terminal is arranged to register as said first public identity said fully unambiguous identity of the user and for said first public identity an address combination according to the domain name or a numeric IP address of the terminal.

12. The system according to claim 11, wherein the address combination registered by the terminal for said first public identity is privileged.

13. The system according to claim 9, wherein the terminal and the multimedia service network are arranged to establish a double connection such that the first connection is established with the first public identity and the second connection is established with the second public identity.

14. The system according to claim 13, wherein:

the multi bearer service gateway is arranged to specify an address of a transfer end point of real-time information of the terminal in said multimedia core network and relay said address of the transfer end point of real-time information to the terminal in connection with a connection establishing procedure of said second connection,

said transfer end point to be reached or a second multi bearer service gateway is arranged to specify the address of the transfer end point of real time information of said transfer end point to be reached in said multimedia core network and relay the address of the transfer end point of said real-time information of said transfer end point to be reached to the first multi bearer service gateway in connection with the connection establishing procedure of said first connection.

15. A multi bearer service gateway arranged to interface at least a wireless access network for providing access to the terminal and a multimedia core network, wherein:

the multi bearer service gateway comprises means for registering a first public identity and a second public identity for the user of the terminal, wherein the multi bearer service gateway is arranged to

register a fully unambiguous identity of the user as said first public identity, and

register for said first public identity an address combination according to a fully unambiguous domain name formed by said fully unambiguous identity of the user and the domain name or a numeric IP address of the multi bearer service gateway.

16. The multi bearer service gateway according to claim 15, wherein the multi bearer service gateway is further arranged to:

register as said second public identity the address combination registered for said first identity, and

register for said second public identity an address combination according to a fully unambiguous domain name formed by said fully unambiguous identity of the user and the domain name or a numeric IP address of the multi bearer service gateway.
