Method and device for large traffic simulation test of packet data service

The invention discloses a method and device for grouping data service bulk call simulation test. The characteristic is that, according the test configuration parameters of background control, it can establish ppp connect through grouping data service node and data resources modules which comprise general protocol stack and simulation terminal, bearing ICMP TCP datagram on ppp link. Using sending/response and flow made by data resources modules, the capability of managing grouping data service on base station system is validated through analyzing the related data. The present invention can be applied on different flat roof and system, and it can test fully the fundamental channel and add channel. At the same time, it can simulate grouping data service of base station system.
