Learn how to use CAMEL to transfer the Intelligent Network concept to the mobile world! CAMEL (Customized Application for the Mobile network Enhanced. The CAMEL architecture is based on the Intelligent Network (IN) standards, and uses the CAP protocol and it is particularly effective in allowing these services to. Before CAMEL, the GSM networks used INAP (Intelligent Network Application Part) for injecting intelligence in GSM networks. The limitations of INAP was that it.

What this means is that the end user should be able to roam between different networks maybe in different countries and be reachable at the same number and should receive only one bill from the original service camel intelligent network Home Operator.

CAMEL: An Introduction

The limitations of INAP was that it did not support mobility management. CAMEL solved the mobility management problem and provided with much more functionality.

The last section in this primer lists the functionality of each phases. Camel intelligent network latest Phase is Phase 4. CAMEL feature is a network feature and not a supplementary service. CAMEL procedures are applicable camel intelligent network all circuit switched basic services without distinction except Emergency calls.

Intelligent Networks (IN) and CAMEL

Take a simple scenario of a voice call being made. This camel intelligent network effectively hosts a database which holds the instructions needed for an intelligent application.


The call is then connected in the most appropriate manner, a process which is transparent camel intelligent network the customer. For example, when an account balance reaches zero for a pre-paid customer under phase 1, the customer will simply be cut off.


With phase 2 thanks to support for SRF, the customer will hear automatically generated messages from the Voice Response Unit warning that the balance is dangerously low before a call and even during the call.

Naturally this leads to greater customer satisfaction. Technical Terms For any further discussions we would need to use some technical terms. Proportional call distribution such as between two or camel intelligent network call centres or offices Call camel intelligent network Call camel intelligent network History and key concepts[ edit ] The IN concepts, architecture and protocols were originally developed as standards by the ITU-T which is the standardization committee of the International Telecommunication Union ; prior to this a number of telecommunications providers had proprietary implementations.

Intelligent Network - Wikipedia

This core would then provide a basis upon which operators could build services in addition to those already present on a standard telephone exchange. The standards defined a complete architecture including the architectural view, state machines, physical implementation and camel intelligent network.

They were universally embraced by telecom suppliers and camel intelligent network, although many variants were derived for use in different parts of the world see Variants below.


Following the success of CS-1, further enhancements followed in the form of CS Although the standards were completed, they were not as widely implemented as CS-1, partly because of the increasing power of the variants, but also partly because they addressed issues which pushed traditional telephone exchanges to their limits.

The major driver behind the development of the IN was the need for a more flexible way of adding sophisticated services to the existing network.

This made for long release cycles as the software testing had to be extensive and thorough to prevent camel intelligent network network from failing. With the advent of the IN, most of these services such as toll-free numbers and geographical number portability were moved out of the core switch systems and into self-contained nodes, creating a modular and more secure network that allowed the service camel intelligent network themselves to develop variations and value-added services to their networks without submitting a request to the core switch manufacturer and waiting for the long development process.

The initial use of IN technology was for number translation services, e. SS7 architecture[ edit ] The main concepts functional view surrounding IN services or architecture camel intelligent network connected with SS7 architecture: This query is usually called a trigger.

Trigger criteria are defined by the operator and might camel intelligent network the subscriber calling number or the dialed number. The SSF is responsible for controlling calls requiring value added services.
