Signaling service processing platform

Signaling Processing Subsystem

The signaling processing subsystem provides the following functions:

• 
  Standard Diameter agent function function (The supported Diameter agent types include Relay agent and Proxy agent.)
  
• 
  STP service processing
  
• 
  Flexible SIP routing
  

Data Storage Subsystem

The data storage subsystem consists of the database platform and disk array. It provides permanent data storage and third-level data backup and restore function. This subsystem only serves as a device for storing data permanently and is independent of service processing.

Data Service Subsystem

The data service subsystem provides data services that are independent of service applications. It supports distributed data storage and data caching in the memory.

Subscriber Data Management Subsystem

As a bridge between the provisioning system/PGW Web LMT and the convergent database, the subscriber data management subsystem implements the following functions:

• 
  Converts the format of the operation commands received from the provisioning system/PGW Web LMT into the format required by the convergent database.
  
• 
  Sends the operation results to the provisioning system/PGW Web LMT.
  

O&M Subsystem (OMU and LMT)

The O&M subsystem provides configuration, management, and maintenance functions.
