请求计时到引起手机WAP接入失败的协议分析Protocol Analysis of MS Web Access Failure due to Request Timed out
林巍,曹若云
摘要(Abstract)：
针对请求计时到引起GPRS网络中手机WAP接入失败的情况,从WAP协议栈中的WSP协议层、WTP协议层、GPRSRLC/MAC协议层以及GSMUm接口第三层对同时在GPRSGb接口和GSMUm接口采集到的消息进行了关联的协议分析。分析结果表明,请求计时到引起GPRS网络中手机WAP接入失败是由于在超时重传消息过程中手机侧的WTP协议层无响应所致,与GPRS无线承载网络及GSMUm接口无关。
