Embodiment Construction

[0031] According to the characteristics of the existing CDMA emulation large traffic system and the characteristics of the front desk, the present invention proposes to adopt a general protocol stack and an emulation terminal to establish a PPP connection with the PDSN, and carry ICMP (Internet Control Message Protocol, Internet Control Message Protocol) on the PPP link. Message Protocol), TCP (Transfer Control Protocol, Transmission Control Protocol) messages, through the statistical analysis of relevant data, verify the performance of the packet data service processing of the CDMA base station system.

[0032] The large traffic emulation test device (or test system) for packet data service of the present invention is mainly to make up for the deficiency of test terminals and test means.

[0033] The packet data traffic simulation system of the present invention includes a control background, a simulation software system (signaling simulation module, special protocol processin...

Abstract

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.

Description

technical field [0001] The invention relates to a large-traffic simulation test of a communication system, in particular to a method and device for testing a large-traffic test of a packet data service in a cellular mobile communication system. Background technique [0002] The third generation mobile communication system, multimedia data communication integrating voice, data and image will be widely used. The third-generation mobile communication system mainly uses high-speed packet data services for data transmission, and has greatly enhanced the transmission of packet data in wireless channels and network access devices. The main data applications include uploading and downloading, streaming media and browsing web pages etc., using the standard TCP / IP protocol suite. [0003] The wireless access system includes a base station system (BSS, Base Station System) and an Internet access device PDSN (Packet Data Serving Node). Generally, a base station system consists of a BSC...
