Difference Between Full IMS and Light IMS

Full IMS (IP Multimedia Subsystem) and Light IMS are two different architectural approaches in the IMS category. Here are the key differences:

Full IMS:

• Full IMS implements the complete set of IMS functionalities, including core network elements such as CSCF (Call Session Control Function), HSS (Home Subscriber Server), and MGCF (Media Gateway Control Function).
• It offers a comprehensive suite of services, including voice over IP, video calling, multimedia messaging, and presence services.
• Full IMS is typically deployed by large telecom operators who require a robust and feature-rich IMS solution.

Light IMS:

• Light IMS is a stripped-down version of IMS that focuses on providing basic IP telephony services without the full range of IMS functionalities.
• It is designed for smaller operators or businesses that need a simpler and more cost-effective solution for enabling IP-based communication services.
• Light IMS may not include advanced features such as video calling, multimedia messaging, and presence services.

Overall, the choice between Full IMS and Light IMS depends on the specific requirements and budget constraints of the operator or organization deploying the IMS solution.
