摘要
3G的成功主要取决于业务,WCDMA系统采用开放的业务平台,使具体的业务与网络承载相分离,极大地提高了业务的灵活性,终端的设计也更加开放。与GSM业务相比,WCDMA业务的提供方式有较大变化,其业务价值链更为丰富。另外,WCDMA的业务完全兼容GSM/GPRS的业务。本文对以上内容进行了分析和讨论。
It is well known that the success of 3G will mainly depend on the services. WCDMA system use open service platform to split the concrete services and network bearer, and improve the flexibility of service supply greatly. The design of mobile terminal is also much open. Comparing with the service supply methods of GSM, that of WCDMA change very much, and the service value chain of WCDMA is richer than that of GSM. Otherwise , WCDMA services contain GSM/GPRS services completely.
