Huawei Unified Subscriber Centre adopt distributed architecture design;

The system is separated into service part (FE) and data part (BE);

FE is responsible for handling business logic, not store any data; BE responsible for the

management of data services, all user data is stored in the BE;

The USC BE provide standard data access interface to USC FE;

Unified Subscriber Centre can be divided into four logical: Signaling access layer, Service logic layer,

data routing layer, data service layer;

Each layer is based on a distributed design, a cluster management, all logic unit to cluster approach,

the logic of the same cluster of modules to load sharing means to achieve the same functionality;
