The AC consists of two logical modules: Charging and Importing Module and Online Accumulation Module. These two modules are correlated in terms of function implementation, since the service functions they provide require both online feature and data integrity.
Online Handler:The Online Handler is the entry of SNSP messages, and also the entry of SNSP Agent callback function.
Batch Handler:The Batch Handler is the entry of charging requests that are presented in CDR data files, or CDRs organized and presented as charging tasks
Accounting Logic Handler:The Accounting Logic Handler is the core module required to enable charging control, importing the usage into the database and online accumulation
SNSP-SNMP based Applciaton messaging
RAI-Remote Access Interface
SERVER CLUSTER
1+1 active/standby mode
N+1 load balancing mode.
LOAD BALANCING
The PSC works in N+1 load sharing mode.
The call server polls multiple PSC servers to achieve load balancing.
DB RECONNECTION
An important means for service reliability
PERFORMANCE
Processes CDR(Charging and Importing) up to 10,000 per Second, over 4.5 Billion/ Day
THREAD POOL DYNAMIC SCHEDULE
Enables the functions for management on cross-platform threads and queues and makes full use of system hardware resources and enhances service performance
REAL-TIME CACHE DB
High speed data access by operations in the memory
Ensures uninterrupted service provisioning
Provides an automatic synchronization mechanism to ensure data synchronization between servers.
