『伍』 GPRS英文文献中文翻译
GPRS是通用分组无线业务(General Packet Radio Service)的英文简称,是在现有的GSM系统上发展出来的一种新的分组数据承载业务。GPRS与现有的GSM语音系统最根本的区别是,GSM是一种电路交换系统,而GPRS是一种分组交换系统。因此,GPRS特别适用于间断的、突发性的或频繁的、少量的数据传输,也适用于偶尔的大数据量传输。这一特点正适合大多数移动互联的应用。
GPRS有什么优点?
实时在线:“实时在线”,即用户随时与网络保持联系。举个例子,用户访问互联网时,手机就在无线信道上发送和接受数据,就算没有数据传送,手机还一直与网络保持连接,不但可以由用户侧发起数据传输,还可以从网络侧随时启动push类业务,不象普通拨号上网那样断线后还得重新拨号才能上网冲浪。
按量计费:用户可以一直在线,按照用户接收和发送数据包的数量来收取费用,没有数据流量的传递时,用户即使挂在网上,也是不收费的。
快捷登录:GPRS的用户一开机,就始终附着在GPRS网络上,每次使用时只需一个激活的过程,一般只需要1-3秒的时间马上就能登录至互联网。
高速传输:GPRS采用分组交换的技术,数据传输速率最高理论值能达171.2kb/s。电路交换数据业务,速率为每秒9.6K比特,因此电路交换数据业务(简称CSD)与GPRS的关系就象是9.6K Modem和33.6K、56K的Modem的区别一样。
自如切换:GPRS还具有数据传输与话音传输可同时进行或切换进行的优势。也就是说用户在用移动电话上网冲浪的同时,可以接收语音电话。电话上网两不误。
GPRS能给用户带来什么?尤其与现有GSM不同的应用业务?
GPRS移动数据业务能够为用户提供丰富的应用服务,如:
移动商务:包括移动银行,移动理财,移动交易 (股票,彩票) 等
移动信息服务:信息点播,天气,旅游,服务,网页,新闻和广告等
移动互联网业务:网页浏览,Email等
虚拟专用网业务:移动办公室,移动医疗等
基于位置的业务:位置查询,饭店及类似的服务行业导航等
多媒体业务:可视电话,多媒体信息传送,网上游戏,音乐、视屏点播等
个人服务业务:PIM等为个人量身定做的业务,等等。
值得注意的是, GPRS还有资源共享、丰富带宽等的特点,它本身不是一种业务,而是一种更好的网络承载方式,因此即使是相同的应用也会因为GPRS的上述特点而得到提升,当然由于GPRS本身的技术特点,也有一些特别适合于GPRS网络的应用服务,如网上聊天、移动炒股、远程监控、远程计数等小流量高频率传输的数据业务。
GPRS的应用
GPRS是支撑中国移动"移动梦网"、迈向3G世界的主流技术。
目前中国移动GPRS网络已覆盖全国所有省、直辖市、自治区,网络遍及240多个城市。无论在繁华的闹市、还是在僻静的边远地区,GPRS都能够最大限度的为新人类、商务人士和各行业集团客户提供高速数据服务。
全球200多个最大的运营商都选择了GPRS网络,GPRS数据业务可以触及世界各地。同时中国移动的用户已经可以与香港、台湾、新加坡实现GPRS自由通信,实现真正的移动数据无线互联的概念。
关于手机
世界各大手机厂家,都有GPRS手机提供,目前市面上销售的GPRS手机就有二十多款,并且各个档次的手机都有。彩屏、丰富、功能强大、支持多媒体将是今年GPRS手机的特点。
GPRS从2002年5月17日起正式商用。中国移动正在积极筹划,以完善的客户服务和丰富的应用内容推出市场,应用服务供应商、手机厂商,都已经准备好,将与中国移动一起,全力为用户提供全新的无线数据通信服务。
现在中国移动GPRS服务正在试商用,GPRS手机用户可以申请使用。正式商用时,如果您买了GPRS手机,还需要申请开通GPRS业务功能。申请开通GPRS业务功能就和开通其他新业务一样,到营业厅填写业务变更表或直接打电话1860申请开通即可。
如何申请使用GPRS
1. 如何申请使用GPRS服务?
现在中国移动GPRS服务正在试商用,GPRS手机用户可以申请使用。正式商用时,如果您买了GPRS手机,还需要申请开通GPRS业务功能。申请开通GPRS业务功能就和开通其他新业务一样,到营业厅填写业务变更表或直接打电话1860申请开通即可。
2. GPRS如何收费?
目前GPRS按流量进行计费,用户可以选择以下四种套餐:
- 月租费(元) 赠送的免费流量数(MB) 超过免费流量后的费用(元/KB)
自由套餐 0 0 0.03
经济套餐 20 1 0.01
时尚套餐 100 20 0.01
商务套餐 200 不限量使用
另外,用户漫游不加收漫游费。 申请GPRS 功能不需要开户费,您只要拨打电话1860或到营业厅申请开通GPRS服务即可。
3. 按量收费和按时间收费有什么区别?
按时间收费就是按照从接入网络至与网络断开的时间长度进行计费;按流量收费就是按照接入网络后产生的实际数据比特流来进行计费,接入了网络但没有数据传递是不收费的。例如用户在浏览网页的时候,新打开一个窗口然后进行阅读,产生了5kByte的流量,则只收用户5kB的钱,阅读的时间是不收费的;用户进行网上聊天,在一个小时内发送或者接收了6条信息,流量为1kB,则只收1kB的钱,而不是按一小时来收费;用户下载一首mp3,流量为4M,然后在线收听,则收费为 4M的流量费用,收听的时候是不收费的。GPRS为用户上网提供了一种更好、更快、更优质的服务,而且是完全按照实际流量来收费,收费更合理,因此也能为您省钱。
4. GPRS需要换手机、换号、换卡吗?要不要开户费?
使用GPRS业务就要换一个GPRS手机,不需要换号,不需要换卡,只需要打开GPRS业务功能,无需开户费。
5. 使用GPRS手机如何设置?有何简化程序吗?
使用GPRS 手机需要设一个连接(APN)设置(使用WAP业务设为CMWAP,使用其他www业务使用CMNET),用户名和密码设置为空,其他设置与原来的WAP设置一样。目前ericsson的手机在部分省市能够支持通过短信空中下载GPRS和WAP的设置。
6. GPRS的覆盖和漫游情况如何?可不可以漫游?
目前中国移动GPRS网络覆盖全国16省25个城市,今年10月份马上就可以覆盖全国所有省会城市和大部分大中城市。在国内GPRS覆盖的地方都可以实现GPRS 的自动漫游,且用户漫游不加收漫游费。在没有GPRS网络的时间GPRS 手机还可以用,可以进行正常通话和CSD方式的数据业务,但GPRS的业务就不能使用了。
7. GPRS与原来的CSD(电路交换)拨号方式如何切换?
在进行数据业务之前(如使用WAP)选择使用的连接方式,或者CSD 的拨号方式或者GPRS方式,要切换的话需要先关闭原来的业务再重新进行连接方式的选择。比如:用户启动WAP浏览器,手机会跳出菜单让你选择连接方式,(或默认为缺省的连接设置)如选择了GPRS,那么 用户就会通过GPRS 浏览WAP的各类信息、游戏等,用户要换成拨号接入WAP,则需要推出WAP浏览器,选择连接方式为拨号,再启动WAP浏览器才能切换至拨号(CSD)方式的WAP。
8. 用户购买了支持GPRS的手机之后,可享受哪些新的增值业务?
目前用户可以使用所有原有的WAP上面的信息与娱乐服务以外,还可以通过GPRS手机+笔记本或Pocket PC等设备进行www浏览,另外用户还可以通过GPRS手机直接收发POP3 email、进行网上聊天、网上会议、移动炒股、移动商务、移动娱乐、网上购物等等。
9. 使用GPRS上网时,能否接电话和接收短信?
可以。使用GPRS上网不影响正常的通话和接收短信。
GPRS is General Packet Radio Service (General Packet Radio Service) the title, is in the existing GSM system, developed a new business packet data bearer. GPRS voice with the existing GSM system is the difference between the most fundamental, GSM is a circuit-switched systems, and GPRS is a packet switching system. Thus, GPRS is particularly applicable to intermittent, sudden or frequent, small amounts of data transmission, but also to occasional transmission of large amounts of data. This feature is suitable for the majority of mobile Internet applications.
What are the advantages of GPRS?
Real-time Online: "Real-time Online", that is, users keep in touch with the network at any time. For example, when users access the Internet, mobile phones in the wireless channel on the send and receive data, even if there is no data transfer, mobile phone has also been connected with the network, not only initiated by the user-side data can also be activated at any time from the network side push business, unlike an ordinary dial-up after the break as to have to re-dial-up surfing the Internet.
By the volume of billing: Users can have online, according to the user to receive and send data packets to the number of charges, there is no transmission of data flow, the user, even if linked to the Internet, but also do not charge a fee.
Quick login: GPRS users a boot, it has always been attached to the GPRS network, each using only one activation process, generally only 1-3 seconds will be able to log on to the Internet immediately.
High-speed transmission: GPRS using packet switching technology, data transfer rate up to a maximum theoretical value to 171.2kb / s. Circuit-switched data services, rate of 9.6K bits per second, the circuit-switched data services (referred to as CSD) and GPRS is like the relationship between the 9.6K Modem and 33.6K, 56K, like the difference between the Modem.
Easily switch: GPRS also has the data transmission and voice transmission can be carried out at the same time or switch advantage. This means that users surf the Internet using mobile phones at the same time, you can receive voice calls. Correct telephone line.
GPRS will give the user what? In particular, with different applications of existing GSM business?
GPRS mobile data services to provide users with rich applications, such as:
Mobile Commerce: including mobile banking, mobile management, mobile transactions (stocks, lottery tickets), etc.
Mobile information services: Information on demand, weather, tourism, services, web pages, news and advertising
