In specific embodiment of the invention, cordless communication network, by the cooperation of switch and homing position, can realize the one-number-two-machine business that major number is Home Network number; Also the one-number-two-machine business that major number is outer net number can be realized.Before introducing embodiments of the present invention, first introduce basic office call flow process of the prior art and basic outbound call flow process.
Basic office call flow process, as shown in Figure 1: user dials local exchange number, switch number analysis result is local subscriber, attaching position register is then gone to inquire about called user information, attaching position register returns called UID, and switch is according to the lane place at the UID direct paging user place returned.
Basic outbound call flow process, as shown in Figure 2: user dials outgoing numbers, switch number analysis result is outbound user, attaching position register is not then gone to inquire about, but direct query routing administration module routing iinformation, switch selects corresponding protocol type to be routed to peer switches according to the result of route analysis.
Can be known by above-mentioned two processing procedures, when the major number of two phones just one number is outer net number, in the prior art, switch by directly doing out call treatment, is routed to peer switches after number analysis, and cannot trigger one-number-two-machine business.The present invention uses for reference two kinds of call flows of prior art, proposes the implementation method of the one-number-two-machine business after improvement.The basic thought of the method is: no matter the result of number analysis is outbound call or Home Exchange Call, and system all will to HLR query routing, entire flow as shown in Figure 3:
Step 1: system receives call request, carries out number analysis;
Step 2: using caller UID as inquiry request UID;
Step 3: carry called number and inquiry request UID, inquiry attaching position register;
Step 4: attaching position register is according to called number, and whether inquiry exists corresponding UID: if exist, and inconsistent with inquiry request UID, then return the UID of this correspondence, and proceed to step 5; Otherwise, then return user and do not exist, carry out basic outbound call process;
Basic outbound call process herein can be similar with the basic outbound call of prior art: system direct query routing administration module routing iinformation, selects corresponding protocol type to be routed to peer switches according to the result of route analysis.
Step 5: system, according to the UID returned, obtains supplementary service information; If do not register one-number-two-machine business, then carry out corresponding local basic call process; If register one-number-two-machine business, then system calls out corresponding two terminals simultaneously; Be specially: on the one hand, according to the UID returned, direct calling terminal; On the other hand, number analysis again, using the UID that returns as inquiry request UID, and forwards step 3 to and continues process.
Local call process herein can be similar with the basic Home Exchange Call of prior art: the UID that system returns according to attaching position register, the lane place at direct paging user place.
For above-mentioned basic outbound call process and local call process, different networks according to own characteristic difference to some extent, but as long as can complete outbound call and local call function, may not limit process details.
In said process, called number can be Home Network number, can be more outer net number; Accordingly, two terminals of two phones just one number can be all this network terminations, also can one be this network termination another be outer network termination.
Embodiment 1: major number is Home Network number, two terminals of two phones just one number are this network termination.When there being user to call out this major number, processing procedure as shown in Figure 4:

Step 2: carry called number and caller UID inquiry attaching position register.
Step 3: attaching position register receives routing inquiry, inquiring Home Network according to called number has corresponding user, and the UID of the UID of correspondence and inquiry request is inconsistent, returns the UID of user;
Step 4: switch obtains the supplementary service information of user according to the UID returned, triggers one-number-two-machine business; Be specially:
Step 5: according to the UID called host returned;
Step 6: number analysis again, the UID inquiry HLR carrying called number and return
Step 7:HLR inquires from machine UID, returns this UID;
Step 8: switch according to return from machine UID, call out from machine.
The present embodiment is that two terminals of two phones just one number are this network termination and major number is the situation of Home Network number.Two terminals for two phones just one number adhere to the situation of heterogeneous networks separately, and in the non-present networks of number of distribution during number, the method that the present invention proposes supports one-number-two-machine business equally, sees embodiment 2.
Embodiment 2: off the net outside certain have terminal A, and present networks has certain terminal B, and the telephone number of terminal B opens an account into the number (i.e. major number) of outer network termination A, and terminal B registers two phones just one number supplementary service; The switch configuration route of outer net number section to attaching position register; Attaching position register is configured with outer net number section in the section of this locality.As certain user's calling terminal B, processing procedure as shown in Figure 5:
Step 1: when dialing this major number, analyzes as outbound call;
Step 2: carry called number and caller UID inquiry attaching position register;
Step 3: attaching position register receives routing inquiry, inquiring Home Network according to called number has corresponding user, and the UID of the UID of correspondence and inquiry request is inconsistent, returns the UID of user;
Step 4: switch obtains the supplementary service information of user according to the UID returned, and triggers one-number-two-machine business, calls out this network termination and outer network termination simultaneously;
Step 5: for this network termination, according to the process of basic call flow process, calls out this terminal off the net according to the UID returned; Calling original called party number is remained for outer network termination;
Step 6: number analysis is outbound call again, carries the UID (namely last time step 4 inquires about the UID that attaching position register returns) of called number and Home Network two phones just one number terminal, inquiry HLR;
Step 7: attaching position register inquires terminal corresponding to this number, but consistent with inquiring about the UID carried, return user and do not exist;
Step 8: switch does not exist for user according to the result returned, by basic outbound call process: inquire about out routing iinformation to routing management module, realizes outer net terminal call.
The above embodiments 1 and embodiment 2 have been described in detail two kinds of different one-number-two-machine business.In addition, the method that the present invention proposes is suitable for too to the general office call and outbound call of not registering one-number-two-machine business, and detailed process is shown in embodiment 3 and embodiment 4.
