Problems solved by technology

Using this simulated Gn interface to test IP service packets has the following disadvantages: it is difficult to completely simulate the actual various real IP service packets on the live network, whether it is the length of the packet and its change, the length of the IP packet The type of business (such as FTP, HTTP, VOD, Email, etc.), or the rate of message transmission, etc., cannot find the defects in the GGSN forwarding function that is triggered only by specific application services; let alone feel the data forwarding function of the GGSN The impact on real IP services, for example, a short delay and slight packet loss when GGSN forwards packets, will cause significant playback pauses in VOD demonstration services, and people will immediately recognize the existence of problems
This test method has the following defects: in the encapsulation of uplink data packets constructed by the Gn interface, the "PPP/IP/data" and "PPP signaling" packets carried by GTP are also constructed by test tools, instruments, and software
The disadvantages of this method are: large investment, high cost, and there are often various resource constraints, such as the number of mobile phones, etc., wh

Abstract

The method includes following steps: sets up a protocol conversion unit between the communication node and the host machine in use for running the real traffic at client-side; when the host machine in use for running the real traffic at client side initiates a real traffic, the communication node.

Description

technical field [0001] The invention relates to network communication technology, in particular to a method for testing the real service forwarding function of a gateway GPRS support node and a packet data service node, in particular to a method for testing the real service forwarding function of a communication node. Background technique [0002] The Gateway GPRS Support Node (GGSN) is the core network device of the Global Mobile Telecommunications System (GPRS / UMTS), providing the gateway function between the wireless packet domain core network and the packet data network (such as the Internet), the host or router on the mobile phone and the Internet It plays the role of carrying and forwarding IP service packets. The location of the GGSN in the GPRS / UMTS network is as follows figure 1 As shown, its external interface is as follows figure 2 shown. [0003] Before GGSN products are formally delivered to operators, they need to go through a series of tests such as System...
