Wireless Communication Teaching Platform

Abstract

The invention provides a wireless communication teaching platform which comprises a radio frequency subsystem, a communication access subsystem, a switch, a circuit medium gateway, a main control computer subsystem, a protocol packet capturing and analyzing system and a teaching control system, wherein the radio frequency subsystem is used for being communicated with a mobile terminal; the communication access subsystem is used for receiving uplink information, forwarded by the radio frequency subsystem, of the mobile terminal and sending downlink information to the radio frequency subsystem so that the radio frequency subsystem can forward the downlink information to the mobile terminal in the mode of downlink signals; the circuit medium gateway is used for having access to a fixed terminal; the main control computer subsystem is used for monitoring operation states of the radio frequency subsystem, the communication access subsystem, the switch and the circuit medium gateway; the protocol packet capturing and analyzing system is used for capturing a communication data packet in real time and analyzing a communication protocol; the teaching control system is used for teaching demonstrations of a teacher and student experiments. The teaching platform is low in production cost, has good openness, can cooperate with teaching to enable students to master the work principle of a mobile communication system, is provided with ports so as to be used for scientific researches and is suitable for being used in teaching.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a wireless communication teaching platform. Background technique [0002] TD-SCDMA (TimeDivision-SynchronousCodeDivisionMultipleAccess, Time Division Synchronous Code Division Multiple Access) network, as a technology with independent property rights in my country, has been widely used. From the perspective of teaching and scientific research and cultivating talents, colleges and universities are in urgent need of teaching and scientific research equipment that can realize a complete TD-SCDMA network. However, commercial networking equipment has the following disadvantages: [0003] (1) The realization of a complete TD-SCDMA commercial network requires many types of equipment, a large number, a large volume, difficult deployment and maintenance, and high prices. Universities cannot afford such huge manpower, material and financial resources. However, a single se...

Problems solved by technology

Then, a single set of NodeB equipment cannot be independently networked and authenticated, and can only be used as a decoration

[0004] (2) MSC (MobileSwitchingCenter, mobile switching center), RNC (RadioNetworkController, radio network controller), and NobelB have many system equipment interfaces in commercial equipment, and the networking and authentication are complicated

In addition, due to the consideration of protecting commercial secrets, commercial equipment is very closed and cannot cooperate with teaching to allow students to master the working principle of the equipment, nor does it provide interfaces for scientific research

[0005] (3) The intercommunication between commercial mobile networking equipment and fixed-line telephones needs to further increase interfaces and switching equipment, which increases the cost and complexity of the system
