GPRS：通用分組無線業務 (GPRS: General Packet Radio Service)

GPRS is an abbreviation of General Packet Radio Service. It is a non-voice, high-level speed packet switching technology planned for GSM networks. On 2G and 3G cellular transmission systems, it is a packet aligned wireless data communication service for mobile signal transmission.

GPRS是General Packet Radio Service的縮寫 。 這是為GSM網絡計劃的一種非語音，高速度的分組交換技術。 在2G和3G蜂窩傳輸系統上，它是用于移動信號傳輸的分組對齊的無線數據通信服務。

It operates based on the modulation technique which is also called Gaussian minimum-shift keying (GMSK). To allow GPRS on a GSM or TDMA network, we need to put in two core modules which are,

它基于也稱為高斯最小頻移鍵控(GMSK)的調制技術進行操作。 為了允許GPRS在GSM或TDMA網絡上運行，我們需要放入兩個核心模塊，分別是

• The Gateway GPRS Service Node (GGSN)

  網關GPRS服務節點(GGSN)

• The Serving GPRS Service Node (SGSN)

  服務GPRS服務節點(SGSN)

GPRS有什么作用？ (What GPRS does?)

Based on internet protocols, GPRS can be used to give network connections that favor a broad diversity of enterprises as well as commercial applications.

基于Internet協議，GPRS可用于建立網絡連接，從而有利于廣泛的企業和商業應用。

GPRS的優勢 (Advantages of GPRS)

• In comparison to fixed telecommunication networks, it gives higher data transfer speed. Its prime speed is 171.2 kbps, which is nearly thrice than fixed-telecommunication speed in rapidness.

  與固定電信網絡相比，它具有更高的數據傳輸速度。 它的主要速度為171.2 kbps，在速度上比固定電信速度快三倍。

• It gives quick immediate connection and instant data transfer.

  它提供快速的即時連接和即時的數據傳輸。

• It is very effective in the matter of cost.

  在成本方面非常有效。

• It has original and higher-level applications. It gives applications of the internet over mobile and also makes easier Web browsing, IM messages, E-commerce, etc.

  它具有原始和更高級別的應用程序。 它提供了移動互聯網的應用程序，還使Web瀏覽，IM消息，電子商務等更加容易。

• It enables a user to connect to the Internet even when the availability of other services such as 3G or HSDPA is not there.

  即使沒有其他服務(例如3G或HSDPA)的可用性，它也使用戶能夠連接到Internet。

• In case of mobility, any location from where there is a network signal available, GPRS gives wireless access to the Internet.

  在移動性的情況下(從網絡信號可用的任何位置開始)，GPRS可以無線訪問Internet。

• It enables the concurrent use of both voice and data services. Therefore, a user can have both voice call and data call at the same time. Data call alludes to the use of the internet by browsing or downloading or uploading data.

  它允許同時使用語音和數據服務。 因此，用戶可以同時進行語音通話和數據通話。 數據通話通過瀏覽或下載或上傳數據來暗示互聯網的使用。

• As stated in the GSM standard, GPRS reuses almost identical air interfaces such as TDMA/FDMA, Bursts, frame structure. It makes use of normal burst and access burst stated by GSM.

  如GSM標準所述，GPRS重用了幾乎相同的空中接口，例如TDMA / FDMA，突發，幀結構。 它利用了GSM規定的普通突發和接入突發。

• Single 52 frame multi-frame for both traffic and signaling frame structure is used by GPRS which is different from GSM's dual structure of 26-frame multi-frame for traffic and 51-frame multi-frame for signaling.

  GPRS使用單一的用于通信和信令幀結構的52幀復幀，這與GSM的用于通信的26幀復幀和用于信令的51幀復幀的雙重結構不同。

使用GPRS需要什么？ (What is needed to use GPRS?)

• An application with a GPRS modem.

  帶有GPRS調制解調器的應用程序。

• A GSM/GPRS network.

  GSM / GPRS網絡。

• A SIM card with GPRS service.

  具有GPRS服務的SIM卡。

• A remote station with access to the internet or the GPRS network.

  可以訪問Internet或GPRS網絡的遠程站。

GPRS is contemplated as 2.5G technology due to its more enhanced technology than standard 2G digital technology, but the necessity of 3G technologies it does not fulfill.

GPRS被認為是2.5G技術，因為它比標準2G數字技術增強了技術，但是3G技術的必要性卻不能滿足。
