PDP激活失败，空口上发现大量的Immediate assignment reject，如何分析？可能原因是什么？站点GPRS不可用，话务不高，为了排查问题，配置了4条静态PDCH，就一个站问题，基本可排除资源导致；无线环境良好，无语音问题。 是否还有其他可能原因？ 请各位帮忙。消息内容如下： MS1 Immediate Assignment Reject Time : 00:58:21.90 Vendor Header L2 pseudo length : 19 Skip indicator : 0 Protocol discriminator : (6) Radio resources management messages Message type : 58 Page mode Page mode : (0) Normal paging Request reference Random access representation : 127 (7F hex) Establishment cause : Answer to EGPRS Packet Channel Request FN modulo 42432 : 28256 Representation : T1' = 21, T2 = 20, T3 = 2 Wait1 : 30 Request reference Random access representation : 127 (7F hex) Establishment cause : Answer to EGPRS Packet Channel Request FN modulo 42432 : 28256 Representation : T1' = 21, T2 = 20, T3 = 2 Wait2 : 30 Request reference Random access representation : 127 (7F hex) Establishment cause : Answer to EGPRS Packet Channel Request FN modulo 42432 : 28256 Representation : T1' = 21, T2 = 20, T3 = 2 Wait3 : 30 Request reference Random access representation : 127 (7F hex) Establishment cause : Answer to EGPRS Packet Channel Request FN modulo 42432 : 28256 Representation : T1' = 21, T2 = 20, T3 = 2 Wait4 : 30 RestOctets extRA3 : 11 Message dump (Hex): 06 3A 00 7F A8 54 1E 7F A8 54 1E 7F A8 54 1E 7F A8 54 1E 2B 2B 2B
