Embodiment five

The communication system of present embodiment adopts the network architecture of branch core net mode shown in Figure 9.

Present embodiment is mainly concerned with the improvement of equipment of the core network and subscribed services device.

When needs deletion user, when equipment of the core network sends the removing user message to the subscribed services device, in this message, carry this user's IMSI, can also carry access style;

Particularly, this message is carry-on is combined as: this user's IMSI or this user's IMSI and corresponding access style or this user's IMSI and all corresponding access styles of this IMSI;

After the subscribed services device receives this removing user message,, then the User Status of this access style of this IMSI is stamped unreachable sign if carry this user's IMSI and a kind of access style in this message; If this message is only carried this user's IMSI; All access styles that the IMSI that perhaps carries this user is corresponding with this IMSI are then all stamped unreachable sign with all access styles that this user's IMSI stamps unreachable sign or this IMSI, like this; GMSC is when subscribed services device request route; If the subscribed services device inquires the access style of IMSI that is asked or the IMSI that is asked and has stamped unreachable sign, then directly reply errored response, the errored response value is user's shutdown.

Correspondingly; Information management module in the foregoing description four also can be used for; Receive remove user message after, if carry user's IMSI and a kind of access style in this removing user message, then the User Status of this access style of this IMSI is stamped unreachable sign; If this message is only carried user's IMSI, all access styles that the IMSI that perhaps carries the user is corresponding with this IMSI are then all stamped unreachable sign with all access styles that this user's IMSI stamps unreachable sign or this IMSI.

To combine Figure 12 to realizing that based on the double-mode and double-standby terminal of Fig. 9 system architecture the method for removing mobile subscriber's flow process is described in detail below.

1201; CN1 is according to wherein VLR user's deletion; Perhaps its webmaster operation; Send MAP to HLR/HSS and remove user message (MAP Purge MS), said message is carried double-mode and double-standby terminal user's IMSI or this user's IMSI and corresponding access style or this user's IMSI and two kinds of access styles of this IMSI correspondence;

1202; When HLR/HSS receives that it is IMSI and corresponding access style that said MAP removes user message; Then the User Status of this access style of this IMSI is stamped unreachable sign; If IMSI or 2 kinds of access styles are then stamped unreachable sign with this user's IMSI or the corresponding User Status of all access styles;

After User Status is stamped unreachable sign; GMSC is when HLR/HSS request route; If HLR inquires the access style of IMSI that is asked or the IMSI that is asked and stamped unreachable sign, then directly to GMSC loopback errored response, the errored response value is user's shutdown.

1203, HLR removes the user message response message to CN1 loopback MAP.
