IP-VPN在GPRS网络中的应用

Application of IP-VPN in GPRS Network

GPRS网络将IP网与移动通信网紧密联系起来,GPRS管理数据和用户数据由IP骨干网承载传输。用VPN可以对各种GPRS系统和业务数据进行合理的分离和保护,保证GPRS网络和业务的安全。VPN可以有多种实现方式,包括叠加模式和对等模式。VPN要满足GPRS的需要,取决于运营商的网络环境、客户需求及QOS的重要性。

GPRS network connects IP network and mobile communication network. GPRS management and user data are carried by IP backbone network. GPRS system and service data can be separated and protected through VPN, ensuring the safety of GPRS network and service. There are many ways of realization of VPN, including superposition mode and reciprocity mode. Operator's network environment, customer requirement and QoS are the key factors for VPN to meet the requirements of GPRS.
