自1992年引入GSM后,我国移动通信取得了巨大的发展,在短短8年中我国的GSM用户就超过了6000万,现在我国的移动电话用户已超过日本,居世界第2位。同时,拥有世界最大的GSM移动通信网 在我国移动通信网快速发展的同时,手机质量问题日益为广大用户关注,今年8月,《人民日报》和《人民邮电》相继刊登了反映手机质量问题的报道,引起了各个方面的重视,经过认真总结,我们发现,以往入网检测中存在如下不足: (1)我们目前依据的是1996年颁布的我国通信行业标准,由于当时客观条件的限制,GSM900/1800双频手机的测试没有列入标准。 (2)检验项目的覆盖面不全,我们目前仍按老的进网检验规程检测,测试项目仅涵盖主要的通信功能和射频指标,这些指标虽然是最关键的,但难于通过测试发现手机在长期使用中容易出现的故障。 (3)由于GSM手机在进行FTA测试和入网测试时都只进行一致性测试,因此,手机与不同厂家的基站和交换设备之间的兼容性无法得到验证,即将建成的MTNet将为手机兼容性测试提供测试条件。 (4)由于目前采用的是型号入网,因此每个型号只在最初投产时接受检测,而入网后,厂家再生产的手机缺乏监督约束机制。由于厂家质量把关不严、设计缺陷或者某一批次的零部件质量问题等原因造成各种各样的质量问题,都会直接损害消费者 Since the introduction of GSM in 1992, China’s mobile communications has made tremendous development. In just eight years, China’s GSM subscribers exceeded 60 million. Now China has more mobile subscribers than Japan and ranks second in the world. At the same time, with the world’s largest GSM mobile communications network in China’s rapid development of mobile communications network, mobile phone quality problems are increasingly concerned about the majority of users, in August this year, “People’s Daily” and “people’s Posts and Telecommunications” have published a list of mobile phone quality problems Reported that caused all aspects of attention, after careful summary, we found that in the past there are the following detection of network problems: (1) we are currently based on the promulgation of the 1996 communications industry standards, due to the objective conditions at the time, GSM900 / 1800 dual-band phone test not included in the standard. (2) The coverage of inspection items is not complete. We are still testing according to the old inspection rules. The test items cover only the main communication functions and RF indexes. Although these indexes are the most crucial, it is difficult to find out the long-term use of the mobile phones by testing In the prone fault. (3) Since GSM handsets only conduct conformance testing when conducting FTA testing and network access testing, compatibility between handsets and base stations and switching equipment from different manufacturers can not be verified. The forthcoming MTNet will be compatible with handsets Test provides test conditions. (4) Since models are currently used, each model is tested only when it is initially put into production. However, when it comes into the network, the manufacturer’s mobile phone lacks supervision and restraint mechanism. As the quality of manufacturers lax, design flaws or a batch of parts quality problems and other causes of a variety of quality problems, will directly damage consumers
