Abstract
A first machine-to-machine, M2M, node registering with a second M2M node avoids registration loops using a method that begins with obtaining (710) identifiers for each M2M node with which the second M2M node is registered. The first M2M node refrains (735) from registering with the second M2M node if an identifier for the first M2M node is among the identifiers, registers (725) with the second M2M if the second M2M node is not registered with other M2M nodes, and otherwise: (a) retrieves (740) identifiers for each M2M node with which any M2M on the obtained list is registered, (b) registers (755) with the second M2M node in the event that no identifiers are retrieved, and, (c) if the identifier for the first M2M node is retrieved, refrains (765) from registering with the second M2M node. Steps (a), (b), and (c) may be repeated for identifiers retrieved in step (a).
