Abstract
Secure network location awareness is provided whereby a client is able to use appropriate settings when communicating with an access node of a communications network. In an embodiment a client receives a signed message from the access node, the signed message comprising at least a certificate chain having a public key. In some embodiments the certificate chain may be only a self-signed certificate and in other embodiments the certificate chain is two or more certificates in length. The client validates the certificate chain and verifies the signature of the signed message. If this is successful the client accesses stored settings for use with the access node. The stored settings are accessed at least using information about the public key. In another embodiment the signed message also comprises a location identifier which is, for example, a domain name system (DNS) suffix of the access node.
