ABSTRACT:
A method, system, and media are provided for selecting a preferred roaming partner based on load conditions on an access networks associated with the selected preferred roaming partner. A wireless device storing one or more lists of preferred roaming partners is configured to receive configurations messages from the access networks associated with each of the preferred roaming partners. The wireless device parses the configurations messages and extracts load information from fields included the configuration messages. A load value of each preferred roaming partner is calculated based on the extracted load information. The wireless device selects the preferred roaming partner having the lowest load value to initiate wireless communication over the access network corresponding to the selected preferred roaming partner.
