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.

Claims

1. A method, comprising:

assigning a shared logical device physical network address to each of a plurality of wireless physical devices, where the plurality of wireless physical devices form a logical device group addressable over a single wireless communication channel via the shared logical device physical network address within a wireless network;

translating, in response to receipt of a first data packet addressed to a physical network address of one of the plurality of wireless physical devices from an application server, the physical network address to the shared logical device physical network address with which the one of the plurality of wireless physical devices is logically grouped;

embedding the physical network address of the one of the plurality of wireless physical devices within the first data packet addressed to the shared logical device physical network address; and

sending the first data packet to the shared logical device physical network address.

2. The method of claim 1, further comprising inserting a token in the first data packet addressed to the shared logical device physical network address to cause the one of the plurality of wireless physical devices to initiate transmission of data generated by the one of the plurality of wireless physical devices.

3. The method of claim 2, further comprising:

receiving, in a second data packet comprising a data packet source address of the shared logical device physical network address and a payload with the physical network address of the one of the plurality of wireless physical devices, the data generated by the one of the plurality of wireless physical devices in response to the token inserted into the first data packet addressed to the shared logical device physical network address;

translating the data packet source address of the second data packet from the shared logical device physical network address to the physical network address of the one of the plurality of wireless physical devices; and

sending the second data packet to the application server.

4. The method of claim 1, further comprising:

embedding the physical network address of the one of the plurality of wireless physical devices within a broadcast data packet addressed to the shared logical device physical network address;

embedding a physical network address of at least one additional wireless physical device of the plurality of wireless physical devices within the broadcast data packet addressed to the shared logical device physical network address; and

sending the broadcast data packet to the shared logical device physical network address.

5. The method of claim 1, where:

the wireless network comprises a wireless cellular network; and

wireless physical devices within the plurality of wireless physical devices are configured with each of;

a shared-identity subscriber identity module (SIM) that operates to communicate via the shared logical device physical network address; and

an individual-identity SIM that operates to communicate via the physical network address of the respective one of the plurality of wireless physical devices; and

further comprising;

receiving wireless session information for cellular communication with the logical device group from the one of the plurality of wireless physical devices; and

storing the wireless session information.

6. The method of claim 5, further comprising:

receiving 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;

retrieving the stored wireless session information; and

sending 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 method of claim 6, further comprising:

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

where sending 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 comprises sending 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 method of claim 6, further comprising adding 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.
