<p>An SMSC has a kernel (1), an MN-AIM (12) for interfacing with SMTP interfaces (6) of mobile handsets (1) in a PDC network. An SMPP AIM interfaces with a wireless server (20) via a sub-network layer (14). Signalling between the SMSC (10) and the mobile handsets (1) uses source port, destination port, and segmentation and reassembly fields.</p> |
