Introduction to Signaling Chapter 1 This chapter is designed to provide the student with a presentation of the background, philosophy, and basic terminology, used in Signaling System No. 7 and a brief description of the main elements of the system. OBJECTIVES: Upon completion of this chapter the student will be able to: Explain the terms Subscriber Loop Signaling, Inter- Exchange Signaling, Channel Associated Signaling, and Common Channel Signaling Describe the basic structure of Signaling System No.7 and list at least three application-layer protocols used in GSM Explain the basic functions of OSI reference model layers and the relationship between the model and Signaling System No.7

1 Introduction to Signaling EN/LZT 123 4734 R4A – 1 – GENERAL INTRODUCTION The term signaling is used in many contexts. In technical systems, it very often refers to the control of different procedures. With reference to telephony, signaling means the transfer of information and the instructions relevant to control and monitor telephony connections. Today’s global telecom networks are included in very complex technical systems. Naturally, a system of this type requires extensive signaling, both internally in different nodes (for example, exchanges) and externally between different types of network nodes. In this document we will focus on external signaling. Thus, the term signaling in the following chapters always refers to external signaling traffic. The main purpose of using signaling in modern telecom networks – where different network nodes must cooperate and communicate with each other – is to enable transfer of control information between nodes in connection with: Traffic control procedures as set-up, supervision, and release of telecommunication connections and services Database communication, for example, database queries concerning specific services, roaming in cellular networks, etc. Network management procedures, for example, blocking or deblocking trunks. Traditionally, external signaling has been divided into two basic types (refer to Figure 1-1 ): Access signaling (for example, Subscriber Loop Signaling) This means signaling between a subscriber terminal (telephone) and the local exchange.
