Abstract:
1. An apparatus, comprising: a network controller of a wireless and/or wireline telecommunications network that makes a scheduled determination of an availability of a network resource of a plurality of network resources, of the wireless and/or wireline telecommunications network, based on a determination of success or failure in timely arrival of a status message from the network resource; wherein the network controller comprises a table of a plurality of availability statuses that correspond to the plurality of network resources; wherein, upon an initialization of the network controller, the network controller sends a request for availability status with a heartbeat frequency to the plurality of network resources to initiate a scheduled transmission by the network resources of one or more status messages from the network resources to the network controller at the heartbeat frequency; wherein each of the plurality of network resources performs a scheduled, synchronous transmission of one or more status messages to the network controller to indicate an in-status availability of the respective network resource; wherein the network controller performs a plurality of scheduled, synchronous determinations of an availability of the network resources, wherein a difference between a current time stamp and the timestamp of a most recently received status message that is less than or equal to a pre-determined time interval comprises a success in timely arrival and an “in-service” availability, wherein a difference between the current time stamp and the timestamp of the most recently received status message that is greater than a pre-determined time interval comprises a failure in timely arrival and an out-of-service availability; wherein the network controller performs an update of the availability status from in-service to out-of-service upon the determination of out-of-service availability; wherein the network controller performs an asynchronous update of the availability status that corresponds to the network resource from out-of-service to in-service upon a receipt of another status message of the one or more status mess from the network resource.
