Abstract

Claims (51)

1. A method for supporting remote Subscriber Identity Module (SIM) profile provisioning, comprising:

receiving, by a processor of a Lightweight Machine-to-Machine (LwM2M) server, an indication of a SIM profile update for a LwM2M client computing device from a mobile network operator server;

2. The method of claim 1 , further comprising:

receiving, by the processor of the LwM2M server, a SIM profile package from the mobile network operator server; and

sending, by the processor of the LwM2M server, the SIM profile package to the LwM2M client computing device in one or more additional remote SIM provisioning objects.

3. The method of claim 1 , wherein:

the indication of the SIM profile update for the LwM2M client computing device from the mobile network operator server includes one or more addresses at which a SIM profile package from the mobile network operator server is available for download by the LwM2M client computing device; and

the remote SIM provisioning object includes one of the one or more addresses.

4. The method of claim 1 , further comprising, prior to generating the remote SIM provisioning object:

determining, by the processor of the LwM2M server, whether the LwM2M client computing device supports a radio frequency (RF) band associated with the SIM profile update for the LwM2M client computing device; and

sending, by the processor of the LwM2M server, an indication to the mobile network operator server of a SIM profile update error in response to determining that the LwM2M client computing device does not support a RF band associated with the SIM profile update for the LwM2M client computing device,

wherein generating the remote SIM provisioning object comprises generating, by the processor of the LwM2M server, the remote SIM provisioning object in response to determining that the LwM2M client computing device does support a RF band associated with the SIM profile update for the LwM2M client computing device.

5. The method of claim 1 , further comprising, prior to generating the remote SIM provisioning object:

determining, by the processor of the LwM2M server, whether free memory space for a SIM of the LwM2M client computing device is equal to or greater than a memory requirement for the SIM profile update for the LwM2M client computing device; and

sending, by the processor of the LwM2M server, an indication to the mobile network operator server of a SIM profiled update error in response to determining that the free memory space for the SIM is less than the memory requirement for the SIM profile update for the LwM2M client computing device,

wherein generating the remote SIM provisioning object comprises generating, by the processor of the LwM2M server, the remote SIM provisioning object in response to determining that the free memory space for the SIM is equal to or greater than the memory requirement for the SIM profile update for the LwM2M client computing device.

6. The method of claim 1 , wherein sending the remote SIM provisioning object to the LwM2M client computing device comprises sending, by the processor of the LwM2M server, the remote SIM provisioning object to the LwM2M client computing device using a secure connection.

7. The method of claim 1 , further comprising:

determining, by the processor of the LwM2M server, whether a second remote SIM provisioning object from the LwM2M client computing device indicating that a SIM profile package was successfully downloaded by the LwM2M client computing device was received;

generating, by the processor of the LwM2M server, a third remote SIM provisioning object for the LwM2M client computing device including a profile update trigger indication in response to determining that the second remote SIM provisioning object from the LwM2M client computing device was received; and

sending, by the processor of the LwM2M server, the third remote SIM provisioning object to the LwM2M client computing device.

8. A Lightweight Machine-to-Machine (LwM2M) server, comprising:
