Tutorial: PCS Network Signaling Using SS7
Authors: Yi-Bing Lin and Steven K. DeVries

Personal Communications Services (PCS) facilitates the exchange of
information (voice, data, video, image, etc.) for mobile users independent
of time, location, and  access arrangement. To support PCS, mobile
communications protocols such as EIA/TIA Interim Standard 41 (IS-41) or
Global System for Mobile Communications (GSM) have been defined for PCS
Network (PCN)  inter-system operations. To support interconnection between a
PCN and the Public Switched Telephone Network (PSTN), it is essential that
the mobile communications protocol interacts with the PSTN signaling system
for mobility management and call control. 

This article describes the interactions between a PCN and the PSTN in four
aspects:

1. Interconnection interfaces -- What are the network interfaces between a
PCN and the PSTN? 

2. Message routing -- How is the information exchanged among the PCN/PSTN
network elements? 

3. Mobility Management -- How does a PCN recognize the locations of the
mobile users? 

4. Call Control -- How are the calls set up between the mobile users and the
wireline users? 

To address these four aspects, we consider IS-41 as the mobile
communications protocol  and Signaling System No. 7 (SS7) as the PSTN
signaling protocol. The IS-41 protocol considered in this article is based
on EIA/TIA IS-41 Revision B. We also describe some potential extensions of
the IS-41 protocol based on a draft of IS-41 Revision C. In this article,
``IS-41.C'' refers to EIA/TIA PN-2991, the Baseline Text Draft 3 9-2-94 of
IS-41 Revision C.
