Test implement network load of the communication network like the real system and method

The present application provides a system and method for load tests of network communications with the real network or the like. Said system comprising: a field test apparatus, the test load in the cell to obtain load distribution in the cell; and a peer load generating means based on the load distribution in the cell, load on the network test loading, so that the load to the test load in the network with the communication network and the like. According to the present application, and all traffic for voice traffic and the like, respectively, but only to adjust the data traffic generated in the like when the total load realized; to ensure the same physical resources, consider the spatial distribution similar user, and is load probability density function as the goal, from a statistical sense, more stability and reliability.
