Which SS7 network component is responsible for storing customer information in databases?

The Signal Control Point (SCP) is indeed the correct answer as it plays a crucial role in the Signaling System 7 (SS7) network architecture by storing customer information in databases. The SCP is a component that handles database queries for various services, often interfacing with other network elements to retrieve or update information regarding subscribers, services, and any special features.

In practice, this means that whenever there is a need for information regarding subscriber authentication, call routing, or service provisioning, the SCP accesses its databases to provide the necessary data to the requesting entity, enabling seamless communication and service delivery.

Other components like the Service Switching Point (SSP) primarily focus on establishing and managing the call connections rather than storing customer information, while the Transaction Capabilities Application Part (TCAP) deals with protocols for transferring information between elements, enabling transactions but not storing them itself. The Mobile Switching Center (MSC) is crucial for call processing and mobility management but lacks the dedicated database function that the SCP provides.
