Service linkage control system and method

A service linkage control system and method are disclosed for implementing the service linkage identification and control for detached control channel and data channel in the communication system. The method includes: the linkage strategy management module(102) sends the first service template of the service needing linkage identifying to the deep packet inspection (DPI) identification module(101) in order to identify the service needing linkage identifying, and sends the service identification result and the linkage related information classification to the linkage strategy management module(102) via the DPI identification device information collection database(104) and the linkage information control centre(105); the linkage strategy management module(102) creates the control strategy of the service according to the received service identification result and predetermined control rule, and forwards the control strategy to the DPI control module(103); the DPI control module(103) receives and implements the control strategy.
