Abstract
The disclosed system obtains an international mobile subscriber identity (IMSI) range of multiple UEs operating on a first network. The system obtains a subscription profile and authentication credentials of a UE among the multiple UEs. The system stores the IMSI range, a first subscription profile, and the authentication credentials in a second database of a second network. The second network provides connectivity to the UE when the UE is outside the limited geographical range of the first network. The system receives a request from the UE to connect to the second network when the UE is outside the limited geographical range. The system reduces network traffic by authenticating the UE using the authentication credentials stored in the second database and determining that the service is authorized to be provided to the UE based on the subscription profile stored in the second database without communicating with the first network. Upon authenticating the UE, the system provides the service to the UE.
