Abstract

A method and apparatus are provided to facilitate communications with MTC devices. An apparatus may include processing circuitry configured at least to receive a broadcasted triggering message and to determine whether the triggering message identifies a machine-type communication (MTC) gateway or another device within a capillary network supported by the MTC gateway. The processing circuitry may cause at least a portion of the triggering message to be provided to a device within the capillary network in an instance in which the triggering message identifies the device within the capillary network. The processing circuitry may also be configured to determine an action requested by the triggering message in an instance in which the triggering message identifies the MTC gateway.

Claims

1. An apparatus comprising processing circuitry configured at least to:

receive a broadcasted triggering message;

determine whether the triggering message identifies a machine type communication (MTC) gateway or another device within a capillary network supported by the MTC gateway;

cause at least a portion of the triggering message to be provided to a device within the capillary network in an instance in which the triggering message identifies the device within the capillary network; and

determine an action requested by the triggering message in an instance in which the triggering message identifies the MTC gateway.

2. An apparatus according to claim 1 wherein the processing circuitry is further configured to authenticate the triggering message based upon an authentication field of the triggering message.

3. An apparatus according to claim 1 wherein the processing circuitry is configured to determine whether the triggering message identifies a MTC gateway or another device based upon an abbreviated device identity included within the triggering message, and wherein the abbreviated device identity uniquely identifies the MTC gateway or another device within a geographic area in which the MTC gateway operates but not outside of the geographic area.

4. An apparatus according to claim 1 wherein the processing circuitry is configured to cause at least a portion of the triggering message to be provided to a device within the capillary network by performing protocol and address mapping to protocols and addresses of the capillary network.

5. An apparatus according to claim 1 wherein the processing circuitry is further configured to:

determine whether an indication of a failure to receive is received from another MTC gateway in an instance in which the triggering message identifies the another MTC gateway; and

cause at least a portion of the triggering message to be provided to the another MTC gateway in an instance in which the indication of a failure to receive is determined to have been received.

6. An apparatus according to claim 1 wherein the processing circuitry is further configured to direct a receiver to wake up in accordance with a predefined schedule in order to receive the broadcasted triggering message.

7. A method comprising:

receiving a broadcasted triggering message;

determining, with processing circuitry, whether the triggering message identifies a machine type communication (MTC) gateway or another device within a capillary network supported by the MTC gateway;

causing at least a portion of the triggering message to be provided to a device within the capillary network in an instance in which the triggering message identifies the device within the capillary network; and

determining an action requested by the triggering message in an instance in which the triggering message identifies the MTC gateway.

8. A method according to claim 7 further comprising authenticating the triggering message based upon an authentication field of the triggering message.

9. A method according to claim 7 wherein determining whether the triggering message identifies a MTC gateway or another device comprises determining whether the triggering message identifies a MTC gateway or another device based upon an abbreviated device identity included within the triggering message, and wherein the abbreviated device identity uniquely identifies the MTC gateway or another device within a geographic area in which the MTC gateway operates but not outside of the geographic area.

10. A method according to claim 7 wherein causing at least a portion of the triggering message to be provided to a device within the capillary network comprises performing protocol and address mapping to protocols and addresses of the capillary network.

11. A method according to claim 7 further comprising:

determining whether an indication of a failure to receive is received from another MTC gateway in an instance in which the triggering message identifies the another MTC gateway; and

causing at least a portion of the triggering message to be provided to the another MTC gateway in an instance in which the indication of a failure to receive is determined to have been received.

12. A method according to claim 7 further comprising directing a receiver to wake up in accordance with a predefined schedule in order to receive the broadcasted triggering message.

13. An apparatus comprising processing circuitry configured at least to:

receive a geographical target area message providing a first device identity, a target area and wake up information, wherein the target area corresponds to respective locations of each machine type communication (MTC) gateway that supports a respective capillary network;

subsequently receive a trigger information message having the first device identity, an abbreviated device identity that is shorter than the first device identity and a requested action; and

cause a triggering message to be broadcast within the target area in accordance with the wake up information, wherein the triggering message includes the abbreviated device identity and the requested action.

14. An apparatus according to claim 13 wherein the processing circuitry is further configured to determine one or more base stations that communicate within the target area, and wherein the processing circuitry is configured to cause the triggering message to be broadcast by causing the one or more base stations to broadcast the triggering message within the target area.

15. An apparatus according to claim 13 wherein the processing circuitry is further configured to remove the first device identity from the trigger information message prior to causing the trigger message to be broadcast without the first device identity.

16. An apparatus according to claim 13 wherein the processing circuitry is configured to receive the trigger information message by receiving the trigger information message that also has an authentication field, and wherein the processing circuitry is configured to cause the triggering message to be broadcast by causing the triggering message to be broadcast that also includes the authentication field.

17. An apparatus according to claim 13 wherein the first device identity and the abbreviated device identity are configured to identify any one of a MTC gateway or another device within a capillary network supported by the MTC gateway.

18. An apparatus comprising processing circuitry configured at least to:

cause a geographical target area message to be provided that includes a first device identity, a target area and wake up information, wherein the target area corresponds to respective locations of each machine type communication (MTC) gateway that supports a respective capillary network; and

subsequently cause a trigger information message to be provided that includes the first device identity, an abbreviated device identity that is shorter than the first device identity and a requested action.

19. An apparatus according to claim 18 wherein the processing circuitry is configured to cause the trigger information message to be provided by causing the trigger information message to be provided that also includes an authentication field.

20. An apparatus according to claim 18 wherein the first device identity and the abbreviated device identity are configured to identify any one of a MTC gateway or another device within a capillary network supported by the MTC gateway.
