  • Patent number: 12058197
    Abstract: A method implemented e.g. in a Lightweight Machine-to-Machine (LwM2M) server, comprises establishing a secure communication session with a client and transmitting an observation request to the client. The observation request identifies a first resource at the client, one or more criteria relating to the first resource to trigger a notification to be transmitted from the client to the server, and one or more resources at the client comprising at least one resource other than the first resource, the value of which is to be included in the notification.

  • Publication number: 20220247577
    Abstract: A method of provisioning a device to use a data service provided by a data service provider comprises maintaining a list of unique identifiers of devices to which a trusted certificate has been issued and receiving a data service request for a device. The request will include a unique identifier for the device and a certificate. In response to the data service request, the list of device unique identifiers is consulted in order to verify that the certificate contained in the data service request is a trusted certificate. If the certificate contained in the service request is a trusted certificate, the certificate may then be forwarded to the data service provider.
