Vase telephone call testing system and method based on CDMA system

Abstract

The method includes following steps: multi wireless subscriber terminal equipments are put into a shielding cabinet; the calling control device controls at least one mass traffic analog callmaker to page the wireless subscriber and make mass traffic analog; the mass traffic testing is made for system.

Description

technical field [0001] The invention relates to the field of communications, in particular to a system and method for testing large traffic in a code division multiple access system. Background technique [0002] CDMA (Code Division Multiple Access) is a multiple access technology that is different from FDMA (Frequency Division Multiple Access) and TDMA (Time Division Multiple Access) and distinguishes different wireless users. In the third generation digital mobile communication system IMT-2000 The two major standards WCDMA and CDMA2000 are both CDMA technology. CDMA is a self-disturbing system, all mobile users occupy the same bandwidth and frequency, CDMA assigns a unique code sequence (spreading code) to each user, and uses it to encode the signal carrying information. Knowing the code sequence, the user's receiver decodes the received signal and recovers the original data, so as to realize multiple access. [0003] The long-term stable operation of a large traffic vol...

AI Technical Summary

Problems solved by technology

[0004] 1) Limited to the cost of the user equipment supplier's open protocol, the cost of tool development, etc., the cost is quite expensive and the cost is extremely high;

[0005] 2) It is difficult to centrally control the user equipment, and it is difficult to increase the volume, which cannot meet the requirements of the large traffic test at all;

[0006] 3) For a CDMA multiple access system, the same-frequency interference between two same-frequency cells cannot be well isolated, which limits the number of user equipment and cannot simulate the number of user equipment in a real environment;

[0007] 4) The interface standards of different commercial user equipment are not uniform, and the types of user equipment supported by tools are limited;

[0009] 6) Radiation from user equipment and base stations is harmful to the health of testers
