<p>A call processing method for a connection request including two-way, up/down direction reporting bands, wherein an originating-side communication node (1) manages empty bands in up and down directions for each route, (2) searches a route having up/down empty bands which are larger than up/down reporting bands when a call connection request including two-way, up/down-direction reporting bands is made, (3) receives, if a route can be searched, the call connection request as a two-way communicating call on that route, (4) searches, if cannot be searched, a route having empty bands larger than an up reporting band and a route having empty bands larger than a down reporting band independently of each other, and (5) receives, if the two routes can be searched, the call connection request as a call (route separated call) communicating on separate up-direction and down-direction routes.</p> |
