Thoroughly updated to cover the latest advances in the telecommunications industry, Signaling System # 7, Sixth Edition, addresses the impact of emerging technologies and applications, such as Long Term Evolution (LTE) and 4G networks, on SS7. An all-new chapter onDiameter discusses how to successfully implement SS7-to-Diameter interfaces to bridge 3G and 4G networks. Real-world examples, protocol message details, call flows, and effective migration strategies are included in this practical guide.

Comprehensive coverage includes:

• The SS7 network--international and national planes
• The OSI model
• SS7 protocols and the protocol stack
• Signal units
• Message Transfer Part (MTP), including level 3
• Signaling Transport (SIGTRAN)
• ISDN User Part (ISUP)
• Signaling Connection Control Part (SCCP)
• Transaction Capabilities Application Part (TCAP)
• The evolution to Diameter
