Abstract
The invention discloses a heterogeneous cooperative switching method and a heterogeneous cooperative switching method. The method comprises the following steps that: a calling party and a cooperative switching control device establish and maintain a data domain communication connection; the calling party and the cooperative switching control device perform interaction to select and determine a communication way; related switching resources are marked into a pre-occupied state; the cooperative switching control device forms a corresponding call control table, and distributes the call control table to related switching equipment and the calling party; the cooperative switching control device starts the calling party to initiate the call connection of a voice domain; the calling party initiates a call to specified switching equipment in the voice domain, and establishes connection, and each piece of related switching equipment continuously initiates a voice call to a called party in the voice domain; and the called party picks a telephone up, the calling party and the called party enter a voice call process, and simultaneously the called party establishes a data communication with the cooperative switching control device, wherein the data channel is used for interaction with the cooperative switching control device. By the system and the method, differences among various new and old heterogeneous switched networks and switching equipment are shielded, and a plurality of telecommunication services of new types can be realized.
Description
Technical field
The present invention relates to a kind of network cooperating system and method, relate in particular to a kind of isomery coordinated exchange system and method.
Background technology
Under existing switching architecture, as shown in Figure 1, calling terminal is by switching equipment XHG1, XHG2-----and-XHGn is connected with the called speech of setting up.This handshaking procedure comprises two parts, when calling terminal makes a call, sends called physical number to calling switch from speech domain or data field, and calling switch is sought the route that continues automatically according to called number; Calling switch is initiated called voice call, through the exchange of each section speech trunk line be connected, arrive called exchange, and to called terminal ringing, called get machine after, caller and called users is in the enterprising words that work of speech domain.The defective of this technology is: 1. data communication channel and the Speech Communication passage of not setting up simultaneously between caller and called users and the corresponding exchange equipment, therefore when calling and called enter talking state, can't transmit select command between caller and called users and the switching equipment, also can't carry out information interaction, many new business can't be carried out by this limitation; 2. the exchange of conversing between calling and called, transmission, route resource are controlled selection by switch, and caller and called users does not have right to choose; 3. in case caller and called users is set up conversation, the user both can't independently select the change of transmission route, also can't select the change of talking mode.
In the NGN in future standard imagination, as shown in Figure 2,, can realize resource allocation in the network by the EX control appliance between the switch though the calling and called end can keep data communication and Speech Communication simultaneously with switch.But this technology has following defective: related during promptly calling and called communicate to connect switching equipment EX1, EX2------EXn must be the NGN switching equipment, when if calling and called have a side to belong to have on the non-NGN net or the route that continues non-NGN equipment, side under the non-NGN net switching equipment still can not carry out data communication and Speech Communication simultaneously with switch, can not change by data communications session sound communication mode in the user's communication process.Want to overcome above problem, then must carry out upgrading to the whole network, promptly the whole network all must adopt NGN equipment, and cost is huge.
