Problems solved by technology

However, as recognized by the inventors, although it is now possible to exchange multi-homing service related information between a mobile device and a P-GW in a 3GPP EPC via a 3GPP access network (using the non-access stratum NAS provided by the GTP protocol and EPS Existing Protocol Configuration Option PCO field provided by the protocol), but exchanging multihoming service related information between mobile device and ePDG in 3GPP EPC via untrusted non-3GPP access network is currently not feasible

Embodiment Construction

[0020] As mentioned above, in an environment such as that provided by EPS, it is necessary to enable users to communicate using multiple accesses (including 3GPP access networks and non-3GPP access networks) Individual flows are dynamically routed to specific accesses, eg based on flow characteristics, capacity of available access, user's preferences, operator's policies, etc. This is also known as multi-access PDN connection and IP flow mobility, or multi-homing service. A description of multi-access PDN connections and IP flow mobility, or multi-homing services, can be found eg in 3GPP TR 23.861.

[0021] As mentioned above, the multi-homing service needs to exchange multi-homing service-related information between the user equipment and the 3GPP PE PC through different access networks. However, as the inventors are aware, although it is now possible to exchange multihomed service related information between a mobile device and a P-GW in a 3GPP EPC via the 3GPP access netwo...

Abstract

One object of the present invention, in an embodiment, is a method for the transport of multihoming service related information between User Equipement UE and 3GPP Evolved Packet Core EPC through untrusted non 3GPP Access Network, said method comprising a step of: - transporting multihoming service related information using signaling exchanged for security procedures between UE and an evolved Packet Data Gateway ePDG of said untrusted non 3GPP Access Network.

Description

technical field [0001] The present invention relates generally to communication networks and systems. Background technique [0002] Detailed descriptions of communication networks and systems can be found in the literature, such as, inter alia, in technical specifications published by standardization organizations such as 3GPP (3rd Generation Partnership Project). In these systems, user equipment UE (such as a mobile terminal) accesses the core network through the access network. [0003] The present invention more particularly relates to a multi-access communication system, such as an Evolved Packet System (EPS) comprising an Evolved Packet Core (EPC), which can be implemented via different access networks, including 3GPP access networks and non-3GPP access networks. access. Examples of 3GPP access technologies include GERAN, UTRAN, HSPA, E-UTRAN, and others. Examples of non-3GPP access technologies include WiFi, WiMAX, CDMA, and the like. [0004] EPS is defined in det...
