The below figure shows the interworking option for non-3GPP access over an untrusted access network.
In the absence of these attributes, the mobile node needs to be statically configured with this information and this is proving to be an operational challenge. Any other approaches for discovering these functions such as using DNS or DHCP would result in obtaining configuration from the access network and not from the home network.
Given that the above referenced 3GPP interface is primarily for allowing the mobile node to connect to the 3GPP network through an untrusted access network, the access network may not have any relation with the home network provider and may be unable to deliver the mobile node’s home network configuration.
These attributes can be exchanged by IKEv2 peers as part of the configuration payload exchange. The attributes follow the configuration attribute format defined in Section 3. Additionally, this document uses the following terms:. This is a security gateway defined by the 3GPP system architecture. Length of the IPv4 address field that follows.
Possible values are 0 3ypp 4. A value of 4 indicates the size of the 4-octet IPv4 address that follows. A value of 0 indicates that it’s an empty attribute with a zero-length IPv4 address field primarily used as a request indicator. However, a system architecture using this specification may be tx to enforce some order at both the peers. Length of the IPv6 address field that follows. Possible values are 0 and A value of 16 indicates the size of the octet IPv6 address that follows.
A value st 0 indicates that it’s an empty attribute with a zero-length IPv6 address field primarily used as a request indicator. These attributes can be exchanged by IKE peers as part of the configuration payload, and the currently defined IKEv2 security framework provides the needed integrity and privacy protection for these attributes.
Therefore, this specification does not introduce any new security vulnerabilities.
