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.
Call signaling is a process that is used to set up a connection in a telephone network.all signaling is used in voice over IP (VoIP) systems to establish connections between H.323 endpoints, or between an endpoint and a gatekeeper.
