1. A method, comprising:
encoding a multi-bit roaming policy for an identity provider and each of a plurality of bit-wise combinatorial permutations of the multi-bit roaming policy for the identity provider within each of a plurality of multi-bit Third Generational Partnership Project (3GPP) broadcast identifiers, wherein the multi-bit roaming policy includes a plurality of bits that identify bit-wise roaming policy information for the identity provider; and
configuring the plurality of multi-bit 3GPP broadcast identifiers at a mobile device associated with the identity provider, wherein detecting, by the mobile device, at least one multi-bit 3GPP broadcast identifier of the plurality of multi-bit 3GPP broadcast identifiers being broadcast by a visited radio access network is to trigger the mobile device to perform an authentication with the identity provider.
