5·12地震造成了数万国民的死亡,没有人能够准确预测这场突如其来的灾难。在自然面前,人类显得如此渺小,昔日充满生机的学校、村镇,转瞬成为一片废墟。现代化的通讯网络也在眨眼间灰飞烟灭,即便在基站未遭受物理破坏的成都、重庆等震感涉及到的城市,由于那一瞬间人们对移动通话的争抢,也导致移动网络几乎崩溃,几小时内都无法正常电话。许多人都在责难中国移动与中国联通的服务表现,不过基于目前2.5G网络的基站容量以及所采用的交换技术。在3G上马之前,类似的突发公共事件也许还会继续导致这样的阻塞!在脆弱的2.5G网络面前,我们该如何在突发公共事件中与外界保持联系和进行求救呢?GPRS或CDMA 1X网络也许是唯一的稻草。
The quake killed many tens of thousands of people on the 5.12 earthquake and no one was able to accurately predict this catastrophic disaster. In the face of nature, human beings seem so insignificant, the former full of vitality of schools, villages and towns, and instantly become a ruin. Modern communications networks are also waning in the blink of an eye, even in the base station did not suffer physical damage in Chengdu, Chongqing and other cities involved in the sense of shock, because of the moment people fight for mobile calls, also led to the mobile network has almost collapsed, within a few hours Can not normally call. Many people are blaming China Mobile and China Unicom’s service performance, but based on the current base station 2.5G network capacity and the exchange of technology used. Before the 3G launch, a similar public emergency may continue to lead to such a blockage! In the face of a vulnerable 2.5G network, how should we keep in touch with the outside world in a public emergency and help? GPRS or CDMA 1X The network may be the only straw.
