Device mobility with CoAP

Abstract:

A method performed in a network connected endpoint device having a first address as its current address. The method comprises receiving Constrained Application Protocol (CoAP) signalling from a network server. The received signalling comprises an Observe request for an information resource of the endpoint device. The resource comprises the current address of the endpoint device stored therein. The method also comprises, in accordance with the received signalling comprising the Observe request, sending CoAP signalling to the network server. The sent signalling comprises information about the current address of the endpoint device stored in the resource. The technique also relates to a method of the network server as well as to the endpoint device and the network server.
