爱总,主贴中的图第10步和第11步,箭头画反了吧?
f) The HLR sends Insert Subscriber Data (IMSI, GPRS Subscription Data) to the new SGSN.
g) The new SGSN validates the MS's presence in the (new) RA. If due to regional subscription restrictions or access restrictions (see TS 23.221 [80] and TS 23.008 [79]) the MS is not allowed to attach in the RA, the SGSN rejects the Attach Request with an appropriate cause, and may return an Insert Subscriber Data Ack (IMSI, SGSN Area Restricted) message to the HLR. If subscription checking fails for other reasons, the SGSN rejects the Attach Request with an appropriate cause and returns an Insert Subscriber Data Ack (IMSI, Cause) message to the HLR. If the network supports the MOCN configuration for network sharing, the SGSN may, if the MS is not a 'Network Sharing Supporting MS', in this case decide to initiate redirection by sending a Reroute Command to the RNS, as described in TS 23.251 [83] instead of rejecting the Attach Request message. If all checks are successful then the SGSN constructs an MM context for the MS and returns an Insert Subscriber Data Ack (IMSI) message to the HLR.
