Abstract

A shared logical device physical network address is assigned to each of a set of wireless physical devices. The set of wireless physical devices forms a logical device group addressable over a single wireless communication channel using the shared logical device physical network address within a wireless network. In response to receipt of a data packet addressed to a physical network address of one of the set of wireless physical devices from an application server, the physical network address is translated to the shared logical device physical network address with which the wireless physical device is logically grouped. The physical network address of the wireless physical device is embedded within the data packet addressed to the shared logical device physical network address. The data packet is sent to the shared logical device physical network address.

the processor is further programmed to;

receive, via the communication module, wireless session information for cellular communication with the logical device group from the one of the plurality of wireless physical devices; and

store the wireless session information in the memory.

6. The system of claim 5, where the processor is further programmed to:

receive, via the communication module, a request for the wireless session information from a second of the plurality of wireless physical devices via a communication initiated by the second of the plurality of wireless physical devices using the individual-identity SIM;

retrieve the stored wireless session information from the memory; and

send, via the communication module, the wireless session information to the second of the plurality of wireless physical devices using the physical network address associated with the individual-identity SIM.

7. The system of claim 6, where the processor is further programmed to:

determine whether the second of the plurality of wireless physical devices is registered as part of the logical device group; and

where, in being programmed to send, via the communication module, the wireless session information to the second of the plurality of wireless physical devices using the physical network address associated with the individual-identity SIM, the processor is programmed to send, via the communication module, the wireless session information to the second of the plurality of wireless physical devices using the physical network address associated with the individual-identity SIM in response to determining that the second of the plurality of wireless physical devices is registered as part of the logical device group.

8. The system of claim 6, where the processor is further programmed to add the second of the plurality of wireless physical devices as an active device within a token rotation with other active devices of the plurality of wireless physical devices.
