Background technology
MPTY (Multi Party, MPTY, meeting) business provides a user (party, side) to connect call capabilities in many ways.That is to say that three users or more user carry out two-way communication simultaneously.(Served Mobile Subscriber is meant the mobile subscriber who calls the MPTY operation, and he can control the MPTY business activating under the MTPY call state, is master control side as serviced user.) when having one to activate calling and a maintenance calling, serviced user can call MPTY, to activate calling and keep calling to be merged into the MTPY calling by network operation, make service-user and remote subscriber (Remote Party: its other party user who is meant non-serviced user in the MPTY calling.) intercommunication mutually.And after MPTY set up, serviced user can keep current MPTY, and user in addition converses with meeting, and recovers call-conference later at end of conversation; Perhaps serviced user keeps current MPTY Multi-Way Calling and initiates new a calling; Perhaps serviced user has MPTY to call out and during an ordinary call at the same time, can be alternately with two callings in user's communication or domestic consumer's calling joined in the MPTY Multi-Way Calling.
At present, mobile soft-switching structure owing to its business provide with call out control separately, call out that control is connected separately with carrying, open interface is convenient to the third party provides characteristics such as professional, intelligent, personalization and mobility to obtain application widely.Can control a large amount of media gateway at the next Media Gateway Controller of the framework of mobile soft switch, these media gateway are disperseed to be placed into different positions usually is used to cover a zone in a big way.
Under this networking mode, set up on the one hand the meeting of striding a plurality of media gateway and need take a large amount of bearing resources, along with the quantity of the shared bearing resource of the increase of conference users quantity also can be bigger increase.In addition, the number of users of maximum is 6 sides in present relevant MPTY agreement (expansion H.248 with 3GPP agreement) and practical application, along with the development need of business can realize that more users join in the meeting.And a plurality of meetings of having set up can be coupled together, with realize in larger scope, convention business between the more users.
Describe meeting model in detail with reference to Fig. 1 and Fig. 2 below according to correlation technique.
Fig. 1 shows one according to the meeting model in the typical gateway of the implementation method one of correlation technique; Fig. 2 shows one according to the meeting model in the typical gateway of the implementation method two of correlation technique.
In implementation method one as shown in Figure 1, user A, the B of conference participation, C are connected on the same media gateway, and each user corresponding respectively end points on media gateway is Ta, Tb, Tc.Realize the meeting between user A, B, the C, only three end points need be focused on related CTXa, realize conferencing function by the media gateway audio mixing.
In implementation method two as shown in Figure 2, user A, the B of conference participation, C are connected on the same media gateway, user's corresponding respectively end points on media gateway is Ta, Tb, Tc, and the corresponding independent association of each subscriber endpoints is respectively CTXa, CTXb, CTXc.In order to realize the conferencing function between user A, B, the C, in each user's association, increase end points TA1, TB1, TC1 respectively, set up the related CTXmpty of meeting simultaneously, in this association, increase one to one end points TA0, TB0, TC0 and couple together between with association.Realize conferencing function by the related CTXmpty audio mixing of meeting.
Support conferencing function in existing mobile communications system, meeting (number of users of regulation conference participation mostly is 6 sides most in the agreement) is to realize according to two kinds of network models among figure one and the figure two.
Yet, in present agreement and the relevant standard only at same medium gateway internal, the flow process of an independent meeting and networking.If realize a plurality of meetings are connected together and to adopt and the user in the several meetings in the same gateway is merged together realizes (result who realizes also exist the maximum number of user amount can not surpass 6 restriction in the meeting after the merging) like this.Along with application and development, people need connect a plurality of meetings, thereby converse between realization user in larger scope.As: relevant several meetings that will exist couple together, perhaps the user initiates to set up new meeting in the meeting, and several meetings are linked together, but how to realize a plurality of meetings are connected, in prior protocols and relevant standard, all do not have it is provided solution.
Can learn from above description, the implementation that defines in prior protocols or the standard, be merely able to finish the process of setting up of the single meeting (maximum 6 sides) in the same gateway, if adopt the merging mode, then on the one hand media gateway there is higher requirement, requires media gateway can support to support to surpass in the session of a meeting protocols limit of 6 end points, in the process that meeting merges, need the end points quantity of operating many simultaneously, cause operating efficiency not high, the process that meeting is set up is slower.And in the mode that merges, can not realize being distributed in the merging between the meeting on a plurality of gateways.
Therefore, people need a kind of solution that a plurality of meetings can be connected, and can solve the problem in the above-mentioned correlation technique.
