Abstract

A method and system for communicating between a managed device and a device manager is provided by sending the managed device a message over a first communications channel, and then initiating communication between the managed device and the device manager over a second communications channel in response to the message, wherein the first communications channel and the second communications channel are of different types.

First claim

The invention claimed is:

1. A method for communicating between a managed device and a device manager, the method comprising:
sending a message that is secured using Generic Bootstrapping Architecture (GBA) information or includes GBA push information to the managed device over a first communications channel; and
in response to the message, initiating communication between the managed device and the device manager over a second communications channel that is of a different type than the first communications channel, wherein the first communications channel is a cellular channel and the second communications channel is non-cellular channel;
wherein receipt of the message at the managed device additionally causes communications between the managed device and the device manager over a third communications channel to cease and switch to the second communications channel, wherein the third communications channel is different to the second communications channel; and
wherein the message is sent to the managed device in response to: an increase in data volume; a request to send the managed device a file over a predetermined threshold; a request for a firmware or software update; an increase in electrical power used by the managed device over a predetermined threshold; and a decrease in data transfer rate below a predetermined threshold.

2. The method according to claim 1 , wherein the second communications channel is secure and has a different security architecture to the first communications channel.

3. The method according to claim 1 , wherein the first communications channel is within a first communications system and the second communications channel is within a second communications system different to the first communications system.

4. The method according to claim 1 , wherein the message is SMS or mobile terminated SMS, SMS-MT, WAP-push, or OMA-push.

5. The method according to claim 1 , wherein communications between the managed device and the device manager over the second communications channel are suspended until the message is received.

6. The method according to claim 1 , wherein the managed device is in a dormant state until the message is received.

7. The method according to claim 1 , wherein the message is a secured SMS message, and wherein the SMS message is secured using information established by GBA.

8. The method according to claim 1 , wherein the message is an unsecured SMS messaged containing GBA push information, wherein the method further comprises confirming authenticity of the message using the push GBA information, and wherein communication between the managed device and the device manager over the second communications channel is initiated following successful authentication.

9. The method according to claim 1 , wherein the first communication channel is used to establish cryptographic material to secure the second communication channel.

10. The method according to claim 1 , wherein the managed device is a machine to machine (M2M) device.

11. A system for communicating between a managed device and a device manager, the system comprising:
a device manager;
a first communications channel;
a second communications channel that is different from the first communications channel; and
logic configured to:
send a message that is secured using Generic Bootstrapping Architecture (GBA) information or includes GBA push information to a managed device over the first communications channel; and
in response to the message, initiate communications between the managed device and the device manager over the second communications channel, wherein the first communications channel is a cellular channel and the second communications channel is non-cellular channel;

wherein receipt of the message at the managed device additionally causes communications between the managed device and the device manager over a third communications channel to cease and switch to the second communications channel, wherein the third communications channel is different to the second communications channel; and
wherein the message is sent to the managed device in response to: an increase in data volume; a request to send the managed device a file over a predetermined threshold; a request for a firmware or software update; an increase in electrical power used by the managed device over a predetermined threshold; and a decrease in data transfer rate below a predetermined threshold.

12. The system of claim 11 , wherein the second communications interface is secure and has a different security architecture to the first communications interface.

13. The system of claim 11 , wherein the first communications interface is configured to communicate with a first communications system and the second communications interface is configured to communicate with a second communications system different to the first communications system.
