Abstract: A system, method, and node for releasing resources in a telecommunications network. The method begins by a node assigning a resource-Identification (ID) to an internal resource within the node. At least one internal resource is allocated by the node for a specific Packet Data Network (PDN) connection. Next, a first message containing a resource-ID of the allocated internal resource is sent to one or more peer nodes. The peer nodes store the received resource-ID from the first message. When a node determines that a malfunction of the allocated internal resource of the node occurs, the node sends a second message containing the resource-ID of the malfunctioning internal resource to the peer nodes. The peer nodes then tear down the PDN connection.

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).

Abstract: A system includes a first duplexer that receives samples of a signal transmitted from a first transmit portion of a communication device and outputs a filtered signal based on sampled transmitted signal. A first modulator adjusts the filtered signal based on at least one of a phase, amplitude, and delay of leakage associated with the transmitted signal. The leakage corresponds to leakage from the first transmit portion of the communication device to a first receive portion of the communication device. The first modulator provides a leakage cancellation signal based on the adjusted filtered signal. A first coupler subtracts the leakage cancellation signal from a signal received by the first receive portion of the communication device.
