关于爱总提出的sgsn和hlr的信令交互，我的一些疑问

hycl5410

E.164配置是必须的，请看3GPP TS29.002

NOTE:        For initiating the location updating procedure and an authentication information retrieval from the HLR preceding it, the VLR has to derive the HLR address from the IMSI of the MS. The result can be an SPC or an E.214 Mobile Global Title if CCITT or ITU-T SCCP is used, or IMSI itself if ANSI SCCP is used (ANSI SCCP is used in World Zone 1). When continuing the established update location dialogue (as with any other dialogue) the VLR must derive the routeing information towards the HLR from the Calling Party Address received with the first responding CONTINUE message until the dialogue terminating message is received.

update location 过程不像send authentication过程那样一去一回两条信令就完成了一个dialogue，而是多条信令交互，除了第一条要用E.214之外，其他必须要用E.164的HLR number

谢谢各位的解答
第三步交互应该是LUD
我也觉得HLR的e.164的翻译是需要的，但是我在现网中看到这样的配置： ...

是不是那种从0\*到9\*，不管E214还是E164，统统都指向某一个/一组STP的情况？
最喜欢这种配置了！哈哈~
这种配置方式，7号不通的事基本就不用找SGSN啦~
