Also have a kind of CC (Conference Calling) business at present in wireless network, this business is that promoter (master control side) dials the convention goer one by one, and system adds meeting with it, if the promoter discharges conversation, then whole meeting adjourned.Whole calling procedure is as shown in Figure 1:

A, MS (Mobile Station travelling carriage) send to service MSC (mobile switching centre) and begin to call for to ask message, wherein comprise FC (Feature Code service feature sign indicating number) and TA (telephone number of conference member).

B, service MSC receive the beginning call for ask after, dialing numbers is analyzed, send FEATREQ (FEATURE service request) according to wherein FC to HLR (attaching position register), the TA number of dialing comprising the user (DIGITS).

C, HLR find it is that the conference telephone request then sends featreq (FEATREQ asks response) to service MSC, mainly comprise called number and conference telephone identification parameter CCI, indicate current calling and have activated conference telephone service.

D, service MSC activate conference telephone, and provide business operation confirmation (feature confirmation) according to indication among the featreq to MS, for example are operable to the power amplifier sound.

E, service MSC set up according to called number and call out (calling out to branch 1).

F, user press the SEND key on the MS, and MS sends a FLASH request to service MSC, and request is set up and called out, and carries parameters such as called number.

G, service MSC keep branch 1 (put call-leg 1 on hold).

H, user dial the 2nd branch's number, and MS sends a FLASH request to service MSC, and request is set up and called out to branch 2, carries parameters such as called number.

I, service MSC receive the numeral that the user dials on terminal, set up with TA and call out.

J, MS send a FLASH request (main controlling user is pressed the SEND key) to MSC.

K, MSC connect MS, maintained branch and initiate user, enter the Conference Calling state.

L, send an ending request to service MSC as MS.

M, service MSC discharge MS and participate in all members of CC, and closing session is called out.

Though the professional special videoconference platform that does not need to rely on operator of existing C C, also come with some shortcomings: the CC business belongs to a kind of of multi-link business, and use is restricted; Can only increase the conference member bifurcation approach one by one by the meeting promoter and realize, can't freely select the meeting access way, comprise accessing terminal and the access crowd; In case meeting promoter (master control side) call release, then whole videoconference connects to be interrupted and release, in case non-master control side goes offline for some reason in meeting or leaves, master control side can only issue a separate notice, just can reenter meeting by the master control party call, do not meet call routine meeting use habit, especially be not suitable for the enterprise customer.
