BICC service test method as claimed in claim 11 is characterized in that, the mutual conversion of said Session Initiation Protocol message and Bearer Independent Call Control Protocol message mainly includes: the exchange of (1) SIP calling invitation message (Invite) and BICC initial address message (IAM); (2) SIP calls out the exchange of provisional response response message (1XX) and BICC Address Complete Message (ACM); (3) exchange of SIP call answering response message (200OK) and BICC response message (ANM); (4) exchange of SIP call error or exception response message (4XX) and BICC call progress message (CPG); (5) exchange of SIP call end request message (BYE) and BICC call release message (REL), wherein

(1) SIP calling invitation message (Invite) changes into BICC initial address message (IAM), further includes:

Step D1, R4 analog testing platform extract dialing number information from the FROM territory of SIP calling invitation message (Invite);

Step D2, R4 analog testing platform extract called number information from the TO territory of SIP calling invitation message (Invite);

Step D3, R4 analog testing platform are judged the audio-video frequency media attribute that said SIP calls out according to the medium property of SDP in the said SIP calling invitation message (Invite); If not only had m=audio, but also existed m=video capable, represented then that the audio-video frequency media attribute that said SIP calls out was a video call; As only exist m=audio capable, represent that then the audio-video frequency media attribute that said SIP calls out is an audio call;

Step D4, R4 analog testing platform are according to calling number, called number and the audio-video frequency media attribute information of said SIP calling invitation message (Invite); Generate corresponding BICC initial address message (IAM), wherein " rear subscriber number " in the BICC initial address message (IAM), " called number " and " user service information " correspond respectively to " calling number ", " called number " and " audio-video frequency media attribute " of SIP calling invitation message (Invite);

(2) SIP calls out provisional response response message (1XX) and changes into BICC Address Complete Message (ACM), further includes:

After the R4 analog testing platform receives sip user ALERTING message (180Ring), generate BICC Address Complete Message (ACM), and in said BICC Address Complete Message (ACM), increase optional backward call indicator parameter;

(3) SIP call answering response message (200OK) changes into BICC response message (ANM), further includes:

After the R4 analog testing platform receives SIP call answering response message (200OK), generate BICC response message (ANM);

(4) SIP call error or exception response message (4XX) change into BICC call progress message (CPG), comprise following 4 kinds of situation:

1., for the unregistered message of sip user (404 Not Found)

After the R4 analog testing platform receives the unregistered message of sip user (404Not Found), generate BICC Address Complete Message (ACM), and the reason deictic word parameter field that said BICC Address Complete Message (ACM) is set is called shutdown (Subscriber Absent);

2., for SIP request timed out message (408Request Timeout)

After the R4 analog testing platform receives SIP request timed out message (408Request Timeout); At first generate the BICC Address Complete Message (ACM) of no ring indication; Generate BICC call progress message (CPG) and then, and the reason deictic word parameter field that said BICC call progress message (CPG) is set is called response (No Response);

3., the busy message (486Busy) of sip user

After the R4 analog testing platform receives the busy message (486Busy) of sip user; Generate the BICC Address Complete Message (ACM) of no ring indication earlier; Generate BICC call progress message (CPG) and then, and the reason deictic word parameter field that said BICC call progress message (CPG) is set is Called Busy (Busy);

4., sip user rejection message (486Busy)

When at first receiving sip user ALERTING message (180Ring); The R4 analog testing platform generates the BICC Address Complete Message (ACM) that carries the ring indication earlier; Then when receiving that sip user does message (486Busy); R4 analog testing platform regeneration BICC call progress message (CPG), the reason deictic word parameter field of said BICC call progress message (CPG) is Called Busy (Busy);

(5) SIP call end request message (BYE) changes into BICC call release message (REL), further includes:

After the R4 analog testing platform receives SIP call end request message (BYE), generate BICC call release message (REL), and the reason deictic word parameter in the said BICC call release message (REL) is arranged to normal release.
