Step 100, after the trans-regional telephone-moving of user, the Softswitch that shifts out and move into reports this user's route change information the route service device of its father node respectively, the routing iinformation that reports all comprises the routing iinformation and the action type of user characteristics number, user place Softswitch, and action type is used to distinguish the user and moves into or shift out Softswitch;
Step 110, the Softswitch that the user moves into is set up this user's relevant information with this user's characteristic number; (this characteristic number is carried by the user, does not change with telephone-moving)
Step 120 is received and the route service device of reporting information the route information table is upgraded accordingly according to reporting information, simultaneously route change information is synchronized to the route service device at the same level (also can not specifying) of father node and appointment;
After this step, the information of all having preserved the current place of this user Softswitch in the route service device for this user's service.
Use original characteristic number after user's telephone-moving, the routing procedure of calling out when called may further comprise the steps: (shown in Figure 4 is the not real processes when the same area of calling and called)
Step 200, the characteristic number that other users dial this telephone-moving user makes a call to it;
Step 210, the Softswitch at caller place is searched the information whether this telephone-moving user is arranged according to this characteristic number, if having, at local complete connection, otherwise the route service device to its father node is initiated routing inquiry request, includes this telephone-moving user's characteristic number in the request;

Softswitch SS2 sets up the relevant information of user A1 with the characteristic number of A1;
Route service device RS1 is receiving Softswitch SS1, when the routing iinformation that SS2 reports changes, need to upgrade the route record of user A1 in the routing information base, simultaneously route change information is synchronized to route service device RS3, supposes that herein RS2 is not the route service device at the same level of the appointment of RS1.
Though RS1 will receive the reporting information of SS1 and SS2 respectively, but the action type of SS1 reporting information be with shift out corresponding, when the action type of SS2 reporting information is corresponding with immigration, when carrying out the renewal of route record, for with shift out corresponding reporting information, just upgrade (can only upgrade the routing iinformation that this node was reported and submitted in the past) when only the node in former record is identical with node in the reporting information, otherwise do not do any operation; And for move into corresponding reporting information, as long as recorded information and reporting information are inequality, just can upgrade.Thereby can guarantee that the routing iinformation in the route service device is the current routing iinformation of telephone-moving user.
Then, analyze call flow after telephone-moving is finished:
The telephone-moving user does caller
User A1 is caller calling party B1, because this moment, user A1 and user B1 belonged to the user of same Softswitch SS2, thus belong to the calling territory in, just can call establishment under the control of Softswitch SS2.
User A1 is caller calling party A2, because this moment, user A1 adhered to the user of different Softswitch separately with user A2, so belong to cross-domain call, SS2 need ask the routing iinformation of the Softswitch at inquiring user A2 place to route service device RS1, A2 is in the service range of RS1, the Softswitch that RS1 can find the A2 place is SS1, and the routing iinformation of SS1 returned SS2, after SS2 obtains routing iinformation, forward calling to Softswitch SS1, under the control of Softswitch SS1, finish calling.
The telephone-moving user does called
User B1 is caller calling party A1, because this moment, user B1 and user A1 belonged to the user of same Softswitch SS2, thus belong to the calling territory in, just can call establishment under the control of Softswitch SS2.
User A2 is caller calling party A1, because user A1 this moment telephone-moving goes out Softswitch SS1, adhered to the user of different Softswitch separately with user A2, so SS1 need ask the routing iinformation of the Softswitch at the current place of inquiring user A1 to route service device RS1, after the A1 telephone-moving still in the service range of RS1, the Softswitch that RS1 can find the A1 place is SS2, and the routing iinformation of SS2 returned SS1, after SS1 obtains routing iinformation, forward calling to Softswitch SS2, under the control of Softswitch SS2, finish calling.
User C1 is caller calling party A1, this moment, user C1 belonged to the user of Softswitch SS3, user A1 then belongs to the user of Softswitch SS2, this calling belongs to cross-domain call, need inquire about the routing iinformation of the Softswitch at the current place of called subscriber A1 to the route service device RS2 of SS3 father node request, but because the Softswitch SS1 at user A1 place and the Softswitch SS3 at user C1 place adhere to different route service device RS1 and RS2 separately, so on route service device RS2, can not find the routing iinformation of the Softswitch at the current place of user A1, so RS2 continues inquiry to the route service device RS3 of father node, A1 is in the service range of RS3, RS3 can find the routing iinformation of the Softswitch SS2 at the current place of user A1, the routing iinformation of SS2 is turned back to SS3 through RS2, after SS3 obtains routing iinformation, forward calling to Softswitch SS2, under the control of Softswitch SS2, finish calling.
The whole network number portability service of the present invention can illustrate with following example:
If there is a user in Nanjing, number is: 2871410, and the Nanjing regional number is 025, this user's characteristic number is 0252871410.
If there is not telephone-moving, the Nanjing user dials this user, can directly dial 2871410, and other regional users (as the user in Shanghai) dial this user, then dial 0252871410.
If Beijing has been gone in this user's telephone-moving in Nanjing, suppose that also there is 2871410 Subscriber Number in Beijing, at this moment, the Nanjing user dials this user, still can directly dial 2871410, other regional users (as the user in Shanghai) dial this user, then dial 0252871410, and the user of Pekinese dials this user and dials 0252871410, dials Beijing user with difference and dials big local user 2871410.
