Embodiment Construction

[0017] According to a preferred embodiment of the present invention, there is provided a method for realizing WCDMA base station capacity testing through IUB interface loopback. The loopback may be, for example, an optical port loopback connected by an optical cable, or an E1 port loopback. Optical port loopback and E1 port loopback have no difference in technical solution implementation, only the transmission medium of IUB port is different. The network system diagram of the test method is as follows: figure 1 shown. Usually, the following problems need to be solved when performing NodeB equipment capacity specification testing, namely, how to generate uplink data sources, how to generate downlink data sources, how to loop back uplink and downlink data sources, and what method to use to verify that the base station meets the system full-capacity design specifications , how to observe uplink data, how to observe downlink data, etc.

Abstract

The system includes up going data source, NodeB device, and user terminal to be tested. The data source is in use for generating up going data. NodeB device includes following parts: TRX port in use for receiving the said up going data, and sends wireless signal frame; decoder module in use for decoding the up going data to form protocol packet of up going data channel; IUB interface board in use for receiving the protocol packet of up going data channel, and using a loop back wire to loop back protocol packets of down going data channel; encoder in use for encoding protocol packets of down going data channel to a wireless signal frame, which is sent from transmitting TRX port. The user terminal is in use for receiving frames sent from transmitting TRX port, and detecting the signal. Features are: simple test environment, simple operation. The invention is applicable to validate capacity, specification of NodeB and test activity for NodeB.

Description

technical field [0001] The invention relates to a system for testing the capacity of base station equipment and a method for using the system to test the capacity of the base station. The invention also relates to a method for realizing IUB interface data loopback. Background technique [0002] How to test the maximum service capacity of the complete base station is a problem that system designers are very concerned about. Through the test of the base station service capacity specification, it can be verified whether the signaling and service processing capabilities of the base station meet the product design requirements under full capacity, and it can also be analyzed in which aspects of the base station system there are processing bottlenecks, so as to facilitate the optimal design of the base station. [0003] At present, there is no scheme that can effectively test the capacity specification of NodeB base stations. Contents of the invention [0004] In view of the fo...
