『伍』 GPRS英文文獻中文翻譯
GPRS是通用分組無線業務(General Packet Radio Service)的英文簡稱,是在現有的GSM系統上發展出來的一種新的分組數據承載業務。GPRS與現有的GSM語音系統最根本的區別是,GSM是一種電路交換系統,而GPRS是一種分組交換系統。因此,GPRS特別適用於間斷的、突發性的或頻繁的、少量的數據傳輸,也適用於偶爾的大數據量傳輸。這一特點正適合大多數移動互聯的應用。
GPRS有什麼優點?
實時在線:「實時在線」,即用戶隨時與網路保持聯系。舉個例子,用戶訪問互聯網時,手機就在無線信道上發送和接受數據,就算沒有數據傳送,手機還一直與網路保持連接,不但可以由用戶側發起數據傳輸,還可以從網路側隨時啟動push類業務,不象普通撥號上網那樣斷線後還得重新撥號才能上網沖浪。
按量計費:用戶可以一直在線,按照用戶接收和發送數據包的數量來收取費用,沒有數據流量的傳遞時,用戶即使掛在網上,也是不收費的。
快捷登錄:GPRS的用戶一開機,就始終附著在GPRS網路上,每次使用時只需一個激活的過程,一般只需要1-3秒的時間馬上就能登錄至互聯網。
高速傳輸:GPRS採用分組交換的技術,數據傳輸速率最高理論值能達171.2kb/s。電路交換數據業務,速率為每秒9.6K比特,因此電路交換數據業務(簡稱CSD)與GPRS的關系就象是9.6K Modem和33.6K、56K的Modem的區別一樣。
自如切換:GPRS還具有數據傳輸與話音傳輸可同時進行或切換進行的優勢。也就是說用戶在用行動電話上網沖浪的同時,可以接收語音電話。電話上網兩不誤。
GPRS能給用戶帶來什麼?尤其與現有GSM不同的應用業務?
GPRS移動數據業務能夠為用戶提供豐富的應用服務,如:
移動商務:包括移動銀行,移動理財,移動交易 (股票,彩票) 等
移動信息服務:信息點播,天氣,旅遊,服務,網頁,新聞和廣告等
移動互聯網業務:網頁瀏覽,Email等
虛擬專用網業務:移動辦公室,移動醫療等
基於位置的業務:位置查詢,飯店及類似的服務行業導航等
多媒體業務:可視電話,多媒體信息傳送,網上游戲,音樂、視屏點播等
個人服務業務:PIM等為個人量身定做的業務,等等。
值得注意的是, GPRS還有資源共享、豐富帶寬等的特點,它本身不是一種業務,而是一種更好的網路承載方式,因此即使是相同的應用也會因為GPRS的上述特點而得到提升,當然由於GPRS本身的技術特點,也有一些特別適合於GPRS網路的應用服務,如網上聊天、移動炒股、遠程監控、遠程計數等小流量高頻率傳輸的數據業務。
GPRS的應用
GPRS是支撐中國移動"移動夢網"、邁向3G世界的主流技術。
目前中國移動GPRS網路已覆蓋全國所有省、直轄市、自治區,網路遍及240多個城市。無論在繁華的鬧市、還是在僻靜的邊遠地區,GPRS都能夠最大限度的為新人類、商務人士和各行業集團客戶提供高速數據服務。
全球200多個最大的運營商都選擇了GPRS網路,GPRS數據業務可以觸及世界各地。同時中國移動的用戶已經可以與香港、台灣、新加坡實現GPRS自由通信,實現真正的移動數據無線互聯的概念。
關於手機
世界各大手機廠家,都有GPRS手機提供,目前市面上銷售的GPRS手機就有二十多款,並且各個檔次的手機都有。彩屏、豐富、功能強大、支持多媒體將是今年GPRS手機的特點。
GPRS從2002年5月17日起正式商用。中國移動正在積極籌劃,以完善的客戶服務和豐富的應用內容推出市場,應用服務供應商、手機廠商,都已經准備好,將與中國移動一起,全力為用戶提供全新的無線數據通信服務。
現在中國移動GPRS服務正在試商用,GPRS手機用戶可以申請使用。正式商用時,如果您買了GPRS手機,還需要申請開通GPRS業務功能。申請開通GPRS業務功能就和開通其他新業務一樣,到營業廳填寫業務變更表或直接打電話1860申請開通即可。
如何申請使用GPRS
1. 如何申請使用GPRS服務?
現在中國移動GPRS服務正在試商用,GPRS手機用戶可以申請使用。正式商用時,如果您買了GPRS手機,還需要申請開通GPRS業務功能。申請開通GPRS業務功能就和開通其他新業務一樣,到營業廳填寫業務變更表或直接打電話1860申請開通即可。
2. GPRS如何收費?
目前GPRS按流量進行計費,用戶可以選擇以下四種套餐:
- 月租費(元) 贈送的免費流量數(MB) 超過免費流量後的費用(元/KB)
自由套餐 0 0 0.03
經濟套餐 20 1 0.01
時尚套餐 100 20 0.01
商務套餐 200 不限量使用
另外,用戶漫遊不加收漫遊費。 申請GPRS 功能不需要開戶費,您只要撥打電話1860或到營業廳申請開通GPRS服務即可。
3. 按量收費和按時間收費有什麼區別?
按時間收費就是按照從接入網路至與網路斷開的時間長度進行計費;按流量收費就是按照接入網路後產生的實際數據比特流來進行計費,接入了網路但沒有數據傳遞是不收費的。例如用戶在瀏覽網頁的時候,新打開一個窗口然後進行閱讀,產生了5kByte的流量,則只收用戶5kB的錢,閱讀的時間是不收費的;用戶進行網上聊天,在一個小時內發送或者接收了6條信息,流量為1kB,則只收1kB的錢,而不是按一小時來收費;用戶下載一首mp3,流量為4M,然後在線收聽,則收費為 4M的流量費用,收聽的時候是不收費的。GPRS為用戶上網提供了一種更好、更快、更優質的服務,而且是完全按照實際流量來收費,收費更合理,因此也能為您省錢。
4. GPRS需要換手機、換號、換卡嗎?要不要開戶費?
使用GPRS業務就要換一個GPRS手機,不需要換號,不需要換卡,只需要打開GPRS業務功能,無需開戶費。
5. 使用GPRS手機如何設置?有何簡化程序嗎?
使用GPRS 手機需要設一個連接(APN)設置(使用WAP業務設為CMWAP,使用其他www業務使用CMNET),用戶名和密碼設置為空,其他設置與原來的WAP設置一樣。目前ericsson的手機在部分省市能夠支持通過簡訊空中下載GPRS和WAP的設置。
6. GPRS的覆蓋和漫遊情況如何?可不可以漫遊?
目前中國移動GPRS網路覆蓋全國16省25個城市,今年10月份馬上就可以覆蓋全國所有省會城市和大部分大中城市。在國內GPRS覆蓋的地方都可以實現GPRS 的自動漫遊,且用戶漫遊不加收漫遊費。在沒有GPRS網路的時間GPRS 手機還可以用,可以進行正常通話和CSD方式的數據業務,但GPRS的業務就不能使用了。
7. GPRS與原來的CSD(電路交換)撥號方式如何切換?
在進行數據業務之前(如使用WAP)選擇使用的連接方式,或者CSD 的撥號方式或者GPRS方式,要切換的話需要先關閉原來的業務再重新進行連接方式的選擇。比如:用戶啟動WAP瀏覽器,手機會跳出菜單讓你選擇連接方式,(或默認為預設的連接設置)如選擇了GPRS,那麼 用戶就會通過GPRS 瀏覽WAP的各類信息、游戲等,用戶要換成撥號接入WAP,則需要推出WAP瀏覽器,選擇連接方式為撥號,再啟動WAP瀏覽器才能切換至撥號(CSD)方式的WAP。
8. 用戶購買了支持GPRS的手機之後,可享受哪些新的增值業務?
目前用戶可以使用所有原有的WAP上面的信息與娛樂服務以外,還可以通過GPRS手機+筆記本或Pocket PC等設備進行www瀏覽,另外用戶還可以通過GPRS手機直接收發POP3 email、進行網上聊天、網上會議、移動炒股、移動商務、移動娛樂、網上購物等等。
9. 使用GPRS上網時,能否接電話和接收簡訊?
可以。使用GPRS上網不影響正常的通話和接收簡訊。
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
Mobile internet business: web browser, Email, etc.
Virtual Private Network: the mobile office, mobile medical
Location-based business: location query, restaurants and similar service instries such as navigation
Multimedia services: video telephony, multimedia messaging, online gaming, music, video on demand, etc.
Personal services business: PIM, such as tailor-made for personal business, and so on.
It is worth noting that, GPRS also the sharing of resources, such as the characteristics of bandwidth-rich, it is not a business, but a better way of carrying the network, so even if the application is the same also because the above-mentioned characteristics of GPRS be enhanced, of course, e to the characteristics of GPRS technology in itself, there are also some particularly suitable for the application of GPRS network services such as online chat, mobile stock trading, remote monitoring, remote traffic count, such as high-frequency transmission of data services.
Application of GPRS
GPRS is the support of China Mobile "Monternet", into the mainstream of the world's 3G technology.
At present, China Mobile GPRS network has covered all the provinces, municipalities and autonomous regions, and more than 240 cities across the network.
