随着移动梦网业务的不断扩展,已开通金融股票、体坛风云、铃声图片、生活服务等等实用型业务近百余种。看上去人们似乎可以随时随地的通过手机获取自己所需求的信息。但是随着“移动梦网”业务的不断增多,新的问题出现了。首先是移动用户要将个人数据储存在SIM卡芯片的EEPROM中,如电话号码、短信息等。这就涉及到了SIM卡的容量问题,当前中国移动SIM卡市场上的主流产品的容量是16KB和32KB。但是面对2G的增值业务,无论卡的容量多大似乎都是小。这种局面让移动运营商和服务提供商都相当的尴尬,一面是自己提供的不断增多的信息量,一面是SIM卡内存不可更改的限量。
With the continuous expansion of the Monternet business, it has opened nearly 100 kinds of practical businesses such as financial stocks, sports situations, ringtones pictures, living services and so on. It seems that people seem to be able to get the information they need on their cell phones anytime, anywhere. But with the continuous growth of “Monternet” business, new problems have emerged. The first is to move the user to personal data stored in the SIM card chip EEPROM, such as phone numbers, text messages and so on. This involves the capacity of the SIM card, the current mainstream of China Mobile SIM card market capacity is 16KB and 32KB. But in the face of 2G value-added services, no matter how much the size of the card seems to be small. This situation makes mobile operators and service providers are quite embarrassed, one side is to provide their own increasing amount of information, one side is the SIM card memory can not be changed.
