GPRS 全称 General Packet Radio Service,即通用无线分组业务,是一种基于 GSM 系统的无线分组交换技米,提供端到端、广域的无线 IP 连接。GPRS 是一项高速数据处理技术,以“分组”的形式把资料传送给用户。虽然GPRS 是现有 GSM 网络向第三代移动通信演变的过渡技术,但它在许多方面都有优势。目前,香港作为第一个进行 GPRS 实地测试的地区,已取得了良好成效。由于用了“分组”技术,用户上网可免受断线痛苦。此外,用 GPRS 上网的方法与 WAP 不同,用 WAP 上网时不能用电话线,而用 GPRS 下载资料和通话可同时进行。从技术上讲,声音的传送(即通话)用 GSM,数据的传送则用GPRS,这样就把移动电话的应用提升到更高的层次。GPRS的应用十分广泛,包括用手机发送及接收电子邮件、在互联网上浏览等。现在手机上网的口号是“Always On Lune”、
The full name of GPRS General Packet Radio Service, General Packet Radio Service, is a GSM-based wireless packet switching technology to provide end-to-end, wide area wireless IP connectivity. GPRS is a high-speed data processing technology that delivers data to users in the form of “packets”. Although GPRS is a transitional technology that evolves from the existing GSM network to the third generation of mobile communications, it has advantages in many aspects. At present, Hong Kong has achieved good results as the first region to conduct GPRS field tests. Thanks to the “grouping” technology, users can access the Internet from the pain of disconnection. In addition, the method of using GPRS Internet access and WAP is different, when using WAP Internet access can not use the telephone line, and use GPRS to download data and calls can be carried out simultaneously. Technically, the transmission of voice (ie, talk) with GSM, GPRS data transmission is used, so put the mobile phone application to a higher level. GPRS has a wide range of applications, including sending and receiving e-mail on mobile phones, browsing on the Internet, and more. Now the mobile phone’s slogan is “Always On Lune ”,
