Once released, BNP binds to and activates the atrial natriuretic factor receptor NPRA, and to a lesser extent NPRB, in a fashion similar to atrial natriuretic peptide (ANP) but with 10-fold lower affinity.
The GTP layer for the control plane (GTP-C) tunnels signaling messages between GSNs in the GPRS backbone network.The GTP-C enables several procedures to be performed through the GPRS backbone network, including path management, tunnel management, location management, and mobility management.he GTP layer for the control plane (GTP-C) tunnels signaling messages between GSNs in the GPRS backbone network.
Signaling is used in the PSTN (public-switched telephone network) and in various Internet protocols to set up and terminate circuits, virtual circuits, sessions, and so on. Signals may be included in packets that travel the same network as data, or in a separate network.ignaling is used in the PSTN (public-switched telephone network) and in various Internet protocols to set up and terminate circuits, virtual circuits, sessions, and so on.
