Provided is a method of resource management and call admission control in an access network in a hierarchical manner.The method of resource management and call admission control in an access network includes: (a) collecting resource information on all of devices constituting the access network and hierarchically constructing the resource information on the access network; (b) when a user requests a connection to the access network, hierarchically extracting position information on the access network from the resource information and connecting the extracted position information to link information in the hierarchically constructed resource information; (c) when a user who succeeds in connecting requests call admission control for an IP communication service, determining an availability of the resources of the hierarchically constructed position information; and (d) when the availability is certified, allocating a band required to the IP communication service to the link information and a part of a margin band of a service class to which the user belongs to respond to the call admission control request.

A method of allowing a network communication service user (subscriber) to receive a desired network communication service with a constant (the same) quality regardless of being in a wired or wireless communication environment based on a single service level agreement (SLA) of the subscriber is provided. The method of providing the network communication service with the constant quality regardless of the wired or wireless network environment includes: (a) setting a call control policy for a service so that an SLA (service level agreement) of a network communication service user is available for the wired or wireless network; (b) determining whether the user accesses the network through the wired or wireless network; (c) determining whether the user is a wired network home user or a wired network guest user when the user accesses the network through the wired network; and (d) providing a network communication service requested by the user based on the call control policy based on the determination result of (b) and (c) for the user.
摘要:
A method for controlling call under use of ATM transfer capabilities call gap during the overload of an ATM switching network. The method comprises the steps of accepting a high priority call need first by means of call priority in a given time gap; and accepting the call in an order of DBR, SBR, ABR (ABT), and UBR service, in case that the call priority is the same, or in case that there is no call priority.
摘要:
An improved rare probability connection call registration method using an incomplete call causation message for an asynchronous transfer mode switching system, which includes the steps of receiving a candidate code from an operator and classifying a normal call and an abnormal call with respect to each call when a call cause message is received, increasing the number of completed calls when the received call is normally completed, and judging whether an incomplete call occurred due to the lack of a switching resource or the busy state of the subscriber at a destination in the case of the abnormal call, terminating the call when the cause of the abnormal call is due to another cause except for the lack of the switching resource, or the on-busy of the subscriber, increasing the number of the incomplete calls when the call is incompletely terminated due to the lack of the switching resource or the on-busy of the subscriber, and checking the call completion ratio, and terminating the call when the call completion ratio is greater than a predetermined threshold value that the operator designated, registering the call as the RPCC, informing the resultant operation of the operator terminal, and requesting a call control with respect to the corresponding code.
