Purpose of SS7 Network

Purpose of SS7 Network

1. An interesting feature of SS7 is that, it is a prerequisite for introduction of the following

new services :

(a) The SS7 provides the internal control and network intelligence essential to an ISDN.

(b) Intelligent Network (IN) which uses network elements such as SSP, SCP and intelligent

peripheral (IP), for achieving improved subscriber substation.

(c) Personal Communication Systems (PCS) which uses SS7 to provide personalised voice,

data, image and video communication services that can be accessed regardless of

location, network and time utilizing advanced microcell technology. It enables personalised

billing, personalised numbering (one number for one person at any place at

any time) and time and location independent charging.

2. The primary purpose of SS7 was to access remote database to lookup. This lookup

process has several benefits because the carriers do not have to maintain a full database at

each switching node, but they know how to get the remote data base and find the information

quickly.

3. SS7 achieves, increased revenue generation, additional call charging capabilities,

variety of calling-card services.

SS7 - Purpose

4. SS7, in integration with SPC systems enables quick and efficient call setup and teardown across the network in less than one second. Also, this integration provides for better supervision, monitoring and billing systems integration.

5. SS7 enables full use of the channel for the talk path because the signalling is done out of band on its own separate channel.

6. SS7 achieves enhanced call features such as call forwarding, calling party name/ number display and three way calling. Also with SS7, efficient and secured world wide communication is possible. It also provides, toll free and toll wireline services.

7. It handles the rerouting of network by using automatic protection switching services such as those found in SONET.

8. SS7 uses packet switching concept. Hence SS7 network is capable of preventing the misrouted calls, duplication of call requests and lost packets (requests for service).
