MMS allows mobile users to send and receive messages containing multimedia content like images, audio, video, and rich text. 

• Handling MMS: The MMSC is responsible for handling, storing, and delivering MMS messages. It's similar to an SMS center (SMSC) but is designed to manage more complex and larger multimedia content.

• Message Routing: When a user sends an MMS, it's first sent to the MMSC, which then routes it to the recipient. If the recipient is unavailable or cannot be reached immediately, the MMSC stores the message and attempts redelivery later.

• Interoperability: The MMSC facilitates MMS exchange within and across different mobile networks. This means it ensures MMS can be sent between users on different mobile carriers.

• Adaptation and Conversion: The MMSC can adapt multimedia content for the recipient's device. For example, if a high-resolution image is sent to a device that cannot display it, the MMSC might compress or resize the image.

• Integration with Other Systems: The MMSC interacts with other network elements, such as billing systems for charging purposes, and databases for storing and managing messages and user information.

The MMSC plays a vital role in the mobile communications ecosystem, enabling the delivery of rich multimedia content that enhances the messaging experience beyond traditional text messaging.
