The CAMEL Application Part (CAP) is a protocol used within mobile networks to enable the execution of operator-specific services for GSM and UMTS networks.
It plays a pivotal role in handling call control features and supplementary services beyond the basic call setup.
Key Features:
- Service Control: Allows network operators to implement customized service logic via the Service Control Point (SCP), managing call routing, charging, and more.
- Mobility Support: Adapts to user mobility, ensuring consistent services when users switch networks or roam.
- Event Handling: Responds to predefined events like call attempts, allowing for dynamic service enhancements.
CAP functions on the basis of sending instructions from the SCP to the network elements, executing complex services tailored to user demands.
The CAP (CAMEL Application Part) framework facilitates advanced call control and value-added services in telecommunications. It enables custom service logic and call management through the Service Control Point (SCP), supports user mobility across networks, and enhances services via event handling. CAP's ability to execute complex, user-tailored services is achieved by transmitting SCP instructions to network elements.
