摘　　要：GTP(GPRS tunneling protocol)是GPRS网络中的重要协议,其安全性涉及到GPRS核心网的计费、管理等重要业务。GTP相关业务以及网络产品的测试需要大量GPRS网络设备,因此测试成本昂贵。文中提出基于OpenGGSN建立GPRS核心网隧道安全测试平台,利用OpenGGSN模拟GGSN和SGSN节点,实现GTP协议的通信机制,对GTP协议的业务和安全性进行测试。通过实际应用证明,该平台满足GPRS核心网隧道安全测试要求,可以降低GTP业务测试的成本,为GPRS核心网设备的研发提供了一个实用的测试平台。GTP is an important protocol in GPRS. Security of GTP operation will affect the core network of GPRS,such as billing and management. Testing of GTP operation and network products needs a lot of GPRS equipments with great cost. A security testing platform of GPRS core network based on OpenGGSN is put forward. This platform uses OpenG- GSN to simulate GGSN and SGSN nodes to achieve GTP protocol communication mechanism in operational and security testing of GTP tunnel. Through the practical applications proves that this platform meets the tunnel safety testing requirements of GPRS core network and reduces the GTP operational test costs. It provides a useful platform for functional test in the research and development of GPRS core network equipment.
