METHOD AND SYSTEM FOR CAPABILITY AWARENESS IN STEERING OF ROAMING
Abstract:
Systems and methods are provide to bring network capability awareness to steering of roaming (SoR). A home network includes a capabilities list of visited networks and their associated with the network capabilities. For SoR, he user equipment (UE) maintains a roaming partners list (RPL). The RPL provides a list of visited networks arranged in order of priority/preference (e.g., the first visited network in the RPL has first priority). The first visited network receives a registration request from the UE and relays a corresponding authentication request to the home network. The visited network in the RPL can be reordered when the UE requires a network capability not supported by the first visited network in the RPL, as indicated by the capabilities list. Depending on the implementation, the UE or the home network can make this decision to reorder the RPL.
