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 cooperation system and method, relate in particular to a kind of heterogeneous synergetic switching system and method.
Background technology
Under existing switching architecture, as shown in Figure 1, calling terminal is connected with the called speech of setting up by switching equipment XHG1, XHG2------XHGn.This handshaking procedure comprises two parts, when calling terminal makes a call, from speech domain or data field, sends called physical number to calling switch, and calling switch is according to the called number Automatic-searching route that continues; Calling switch is initiated called voice call, and exchange and connection through each section of speech trunk line, arrive called exchange, and to called terminal ringing, called, get after machine, and caller and called users is in the enterprising words that work of speech domain.The defect of this technology is: 1. data communication channel and the Speech Communication passage between caller and called users and corresponding switching equipment, do not set up simultaneously, therefore when calling and called enter talking state, between caller and called users and switching equipment, cannot transmit select command, also cannot carry out information interaction, much new business cannot 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., once caller and called users is set up call, user both cannot independently select the change of transmission route, also cannot select the change of talking mode.
