Surrogate cellularless roaming
First Claim
Patent Images
1. A method, comprising:
- establishing, by a surrogate cellular device, radio communication with a cellular base station associated with a home location in a private cellular network, the radio communication specifying a cellular identifier associated with a subscriber identity module installed in the surrogate cellular device;
converting, by the surrogate cellular device, the radio communication into messages utilizing an Internet protocol;
performing a cloud-based service that provides routing information for cellularless roaming;
determining an Internet protocol address associated with a SIMless mobile device, the SIMless mobile device having the subscriber identity module removed therefrom and installed in the surrogate cellular device; and
sending, by the surrogate cellular device, the messages via the public Internet in response to the cloud-based service, the messages sent to the SIMless mobile device associated with the Internet protocol address, the messages providing cellularless roaming outside the home location in the private cellular network.

Abstract
Cellularless roaming avoids excess charges in private cellular network. A user swaps a subscriber identity module from a mobile device and into a surrogate cellular device. The surrogate cellular device may then use the subscriber identity module to establish wireless communication in a home location of a private cellular network. The surrogate cellular device, though, may still communicate with the mobile device using the public Internet. Whenever the surrogate cellular device receives a cellular call or data, the cellular call or data may be routed via the public Internet to the mobile device. The user may thus carry the mobile device to any country in the world and avoid roaming charges.

15. A memory device storing instructions that when executed cause a processor to perform operations, the operations comprising:
-
receiving messages sent via the Internet from a surrogate cellular device, the messages utilizing an Internet protocol and converted from radio communications with a cellular base station associated with a home location in a private cellular network, the messages specifying a cellular identifier associated with a subscriber identity module installed in the surrogate cellular device; performing a cloud-based service that provides routing information for cellularless roaming, the cloud-based service determining an Internet protocol address associated with a SIMless mobile device, the SIMless mobile device having the subscriber identity module removed therefrom and installed in the surrogate cellular device; and sending the messages via the public Internet in response to the cloud-based service, the messages sent to the SIMless mobile device associated with the Internet protocol address, the messages allowing the cellularless roaming outside the home location in the private cellular network. - View Dependent Claims (16, 17, 18, 19)
