Abstract
The present invention discloses a method for selecting a real-time service data transmission path, comprising establishing an independent bearer control layer comprising more than one bearer network resource manager between a service control layer and a bearer network. The method further comprises: after a source bearer network resource manager which is connected to the service control layer receives a connection request for a real-time service, orderly selecting and determining, from the source bearer network resource manager towards a destination bearer network resource manager, an intra-domain route path for the real-time service in a management domain corresponding to each bearer network resource manager, and an inter-domain route path between adjacent management domains corresponding to adjacent bearer network resource managers. In addition, the present invention discloses six methods for selecting a real-time service data transmission path based on different strategies. The methods according to the present invention can increase success ratio of routing, and can obtain an optimal route in simple and flexible manners, thus can guarantee reasonable allocation of resources.
