Link model for multi-prefix packet system bearer

A method for a user equipment, comprising:

• establishing a packet data network connection between the user equipment and a first internet protocol network over a radio access network;
• receiving router advertisements from the first internet protocol network and second internet protocol networks over the radio access network via the packet data network connection, wherein the first internet protocol network represents the highest level internet protocol point of attachment to the packet data network connection, and wherein the second internet protocol networks are located on a data path from the first internet protocol network to the user equipment and are logically connected to the packet data network connection;
• and
• passing the router advertisements to a host having an operating system according to internet protocol networking principles.

An apparatus of a first internet protocol network, the apparatus comprising:

• at least one memory comprising computer program code;
• and
• at least one processor,
• wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus at least to:
• establish a packet data network connection between a user equipment and the first internet protocol network over a radio access network;
• map an access of the first internet protocol network within said packet data network connection to a default bearer;
• route router advertisements at the first internet protocol network to the default bearer;
• and
• provide the default bearer associated with the first internet protocol network and a dedicated bearer associated with each of second internet protocol networks logically connected to the packet data network connection, to the user equipment.

A user equipment comprising:

• at least one memory comprising computer program code;
• and
• at least one processor,
• wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus at least to:
• establish a packet data network connection between the user equipment and a first internet protocol network over a radio access network;
• receive router advertisements from the first internet protocol network and second internet protocol networks over the radio access network via the packet data network connection, wherein the first internet protocol network represents the highest level internet protocol point of attachment to the packet data network connection, and wherein the second internet protocol networks are located on a data path from the first internet protocol network to the user equipment and are logically connected to the packet data network connection;
• and
• pass the router advertisements to a host having an operating system according to internet protocol networking principles.
