The average CPU that each calling takies among the protocol stack C takies percentage k3=y3/n3;
Step 504: the average CPU that each calling takies in each protocol stack of root a tree name takies percentage, and the server free system resources that calculates this protocol stack place is the sum of call accepted again:
Protocol stack A place server free system resources is the total p1=(100%-x1) of call accepted/k1 again;
Protocol stack B place server free system resources is the total p2=(100%-x2) of call accepted/k2 again;
Protocol stack C place server free system resources is the total p3=(100%-x3) of call accepted/k3 again;
Step 505: the server free system resources at root a tree name protocol stack place again sum and this conference terminal number m of call accepted compares, if then turn step 507 greater than m, otherwise turns step 506;
Step 506: attempt from all protocol stacks except protocol stack A, B, C of configuration, finding out available protocol stack.By in the AS program, enabling the protocol stack that is in disabled status or initiating the methods such as attended operation to being in the off-state protocol stack, attempt finding out available protocol stack.If can not find available protocol stack, then point out conferencing resource not enough to the user, turn the meeting that step 512 end is being held; If can find available protocol stack D, E, to protocol stack D, E transmitting system resource operating position query messages, after receiving protocol stack D, E reporting system resource use query response message, change step 503 over to, protocol stack D, E carry out steps 503, then protocol stack A, B, C, D, E are repeated above-mentioned steps 504-505;
Step 507: following according to this, lower several comparative results carry out the protocol stack distribution:
If 1. one of them value of p1, p2, p3 is greater than m, then with m terminal of this meeting, be assigned to the system spare resource again in the protocol stack of sum greater than m of call accepted; If p1, p2, p3 are all greater than m, any one that then is assigned among protocol stack A, B, the C is all right.
If 2. p1, p2, p3 value are all less than m, then from p1, p2, p3 three, choose 2 wantonly, or 3 protocol stacks are made up, carry out the again total addition of call accepted of free system resources, until calculate in wherein a kind of combination free system resources the more total sum of call accepted namely stop to make up calculating greater than m, protocol stack in the combination is distributed by the quantity of each protocol stack energy call accepted, until distribute.What now hypothesis calculated is combined as protocol stack A and C, distributes p1 terminal for first protocol stack A, then gives protocol stack C distribution (m-p1) individual terminal;
Step 508: send the meeting registration request to MC;
Step 509: send the conferencing resource request to MP;
Step 510: if meeting is succeeded in registration and the MP resource is sufficient, then send the beginning conference request to MC.If distributorship agreement stack success in front (now supposes to distribute among the protocol stack A p1 terminal, distributed m-p1 terminal among the protocol stack C), all terminals that participate in the meeting are got a front p1 terminal in order, send the corresponding message such as terminal, calling terminal of adding to protocol stack A, terminal in the meeting is removed front p1 terminal other-end in addition, send the corresponding message such as terminal, calling terminal of adding to protocol stack C.Simultaneously, in AS, preserve the corresponding relation of terminal and protocol stack;
Step 511: the Meeting Held success that m terminal-joined arranged;
Step 512: closing session.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that implementation of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
