ABSTRACT:
The present invention discloses a control method for cross-domain call and connection of ASON. Firstly, a multi-layer network structure is constructed; a network element in parent domain corresponds to a child domain and can communicate with the network elements in the child domain; after the input NCCdiof the bottom-layer domain Ddireceives a cross-domain call processing request from the CCCc1at the calling side, it sends the request up to the input NCCfiof the parent domain Dft; the NCCfitransmits a call coordination to the output NCCfo, and NCCfosends a call indication to the CCCc2at the called side through the output NCCdocorresponding to the child domain Ddo; NCCdotransfers a call confirmed to NCCfivia NCCfo, and NCCfitransmits a connection processing request to CCfi; CCfitriggers a local connection processing, and when the parent domain CCfperforms SNC processing during this process, it needs to implement the sub-connection processing of the corresponding child domain and return the SNC Confirmed; CCfireturns the Connection Confirmed to NCCfi, and then to CCCc1via NCCdi. The present invention solves the control problem that the present standards and techniques can not realize the cross-domain call and connection of ASON.
