Apparatus (D) is dedicated to network level admission control for a communications network (NSIP) using a protocol at sub-IP level and including border routers (BR3-k) interconnected by links associated with known characteristic resources and managed by a network management system (NMS3). This connection apparatus comprises control means (CM) that firstly are fed by the network management system (NMS3) with data representative of the links between the border routers of the sub-IP first network (NSIP) and of the associated resources, and that secondly, on receiving a request to transfer a call via the sub-IP first network (NSIP), which call is associated with at least one service criterion and designates another communications network (NIP2) that is connected to the sub-IP network and that is of a different type, are capable of determining from the received data whether resources are available that satisfy the service criterion(a) associated with the call to be transferred, and if so of forwarding the call transfer request to the control apparatus (S2) connected to the network management system (NMS2) which manages the designated other network (NIP2).
Network level admission control apparatus (D) for a set of communications networks comprising a first network using a protocol at a “sub-IP” level (NSIP) comprising border routers (BR3-k) interconnected by links associated with resources of known characteristics and managed by a first network management system (NMS3), the apparatus being characterized in that it comprises control means (CM) fed by said network management system (NMS3) with data representative of said links between border routers (BR3-k) of said network and of the associated resources, and arranged, in the event of receiving a request to transfer a call via said network (NSIP), which call is associated with at least one service criterion and designates a second communications network (NIP2) connected to said first network and of a different type, to make use of said data to determine whether available resources exist that satisfy the service criterion associated with said call to be transferred, and if so to forward said call transfer request to second control apparatus (S2) connected to a second network management system (NMS2) managing said designated second network (NIP2), with said resources being booked only if resources are available satisfying said service criterion in each of the networks involved by said call.
The use of the network level admission control apparatus (D) and the network equipment (S3) according to any preceding claim in sub-IP communications networks selected from a group comprising space-division switching networks, WDM networks, TDM networks, and GMPLS networks.
