Abstract

In an embodiment, there is provided a method for optimization of IP traffic between a User Equipment having access to an IP network via an IP Connectivity Access Network, and an IP connection endpoint in said IP network, for an application allowing a choice in said IP connection endpoint, said method comprising at least one step based on a selection of an IP connection endpoint according to end-to-end IP traffic optimization criteria.

Claims

1. A method for optimization of IP traffic between a User Equipment having access to an IP network via an IP Connectivity Access Network, and an IP connection endpoint in said IP network, for an application allowing a choice in said IP connection endpoint, said method based on a selection of an IP connection endpoint according to end-to-end IP traffic optimization criteria.

2. A method according to claim 1, comprising a step of:

a network topology aware information server TAIS, such as ALTO server, providing information enabling said User Equipment to select one or several IP connection endpoints according to said end-to-end IP traffic optimization criteria.

3. A method according to claim 1, comprising:

upon selection of a new IP-CAN traffic path for an already started application, said User Equipment selecting an IP connection endpoint according to said end-to-end IP traffic optimization criteria, based on information received from an a network topology aware information server TAIS, such as ALTO server.

4. A method according to claim 1, comprising a step of:

upon selection of a new IP-CAN traffic path for an already started application, said User Equipment requesting to a network topology aware information server TAIS, such as ALTO server, information enabling selection of an IP connection endpoint according to said end-to-end IP traffic optimization criteria.

5. A method according to claim 1, comprising a step of:

upon starting an application, said User Equipment selecting an IP connection endpoint according to end-to-end IP traffic optimization criteria, based on information provided by a network topology aware information server TAIS, such as ALTO server.

6. A method according to claim 1, comprising a step of:

upon starting an application, said User Equipment configuring itself for a traffic path associated with an IP connection endpoint selected according to said end-to-end IP traffic optimization criteria.

7. A method according to claim 1, comprising a step of:

upon starting an application, said User Equipment requesting to a network topology aware information server TAIS, such as ALTO server, information enabling selection of an IP connection endpoint according to said end-to-end IP traffic optimization criteria.

8. A method according to claim 1, wherein IP-CAN corresponds to 3GPP EPS, and selection of an IP-CAN traffic path corresponds to selection of a 3GPP or non-3GPP access and/or selection of an Access Point Name for an IP connection or an IP flow belonging to an IP connection.

9. A method according to claim 1, wherein IP-CAN corresponds to 3GPP EPS, and selection of an IP-CAN traffic path corresponds to selection of a 3GPP or non-3GPP access and/or selection of an Access Point Name for an IP connection or an IP flow belonging to an IP connection, according to operator'"'"'s policies provided by a policy server such as ANDSF server.

10. A User Equipment configured to perform a method according to claim 1.

11. A network topology aware information server TAIS, such as ALTO server, configured to perform of a method according to claim 1.
