Technical background
In wireless 3G R4 network and NGN network, core net has all adopted calls out the network's mode that control separates with carrying.Wherein the media gateway controlling in the core net (MGC) part will realize user's functions such as authentication, charging, switching and speech channel exchange, and media gateway (MG) part realizes the Media Stream processing capacity.Existing H.248 or the MGCP agreement realize monitoring service by the topological relation of describing between the end points.With Fig. 1 is example, and as two end points T3, T5 are arranged among the context C1, annexation is two-way connection, and wherein T3 and T5 can simply regard the user of conversation as.If use new end points T1, a T2 that the receiving and sending messages of an end points T3 among the context C1 monitored, wherein T1 monitors the information that T3 sends, and T2 monitors the information that T3 receives.In existing system, satisfy the topological relation that these function needs MGC indicates T1 and T3, T1 and T5, T2 and T3, T2 and T5, be specially and need indicate:
1, in existing context C1, T3 is connected (T3 T5) with T5 is two-way, and all end points among T1, T2 and the C1 are isolated state (no annexation);
2, unidirectional connection is arranged between T1 and the T3, closure is T3 → T1;
3, unidirectional connection is arranged between T2 and the T5, closure is T5 → T2.
Through this process, on MG, can set up annexation as Fig. 2.
Like this, T1 and T2 end points just can be finished the monitoring to the transmitting-receiving of T3 end points.
In the prior art, if the end points number in context is more, such as, under conference model, when simultaneously a plurality of users being monitored, increase when monitoring end points, need indicate the relation between he and his end points of its user, when number of users is many, the topological relation more complicated, no matter MGC or MG, handling process is all cumbersome.
Fig. 3 is the schematic diagram of meeting or MPTY, if at this moment with T6, T7 the T3 end points is monitored, then will indicate following topology:
1.T3, two-way connection (forming the meeting topology) is arranged in twos between T1, T2, the T5.
2.T6 isolated with all end points, annexation is T3 → T6 between T6 and the T3.
3.T7 isolated with all end points, between T7 and T1, T2, the T5 there be unidirectional the connection, closure is T1 → T7, T2 → T7, T5 → T7, shows that T7 can hear T1, T2, T5;
If also will monitor to the user T5 in the conversation, suppose that monitoring end points is T8/T9, what then will become is more complicated.To on basis just now, indicate:
1.T8 isolated with all end points, annexation is T5 → T8 between T8 and the T5.
2.T9 isolated with all end points, between T9 and T1, T2, the T3 there be unidirectional the connection, closure is T1 → T9, T2 → T9, T3 → T9;
In these operations, soft switch will remember that those are to monitor end points, those are monitored end points, and relation wherein, add fashionablely as new participant side, soft switch also needs to know new end points and the relation of monitoring end points, and MG will infer following annexation according to these topologys, flow process and processing are very complicated, are unfavorable for the expansion of new business.
