Abstract
A system that incorporates teachings of the subject disclosure may include an access segment of a mobility network in which network aggregation devices facilitate a transfer of network traffic data received from base transceiver stations, direct probe packets to a targeted base transceiver stations and determine reachability, by way of an expected reply to each probe packet. A change from reachability to unreachability of the targeted base transceiver station or the network aggregation device is determined to be an indication of service impacted outage. Other embodiments are disclosed.
Claims20
An network device comprising:
- a processor;
- and
- a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
- directing a plurality of probe packets to a targeted base transceiver station and a network aggregation device to determine, by way of an expected reply, reachability of the targeted base transceiver station and the network aggregation device, wherein the network aggregation device receives network traffic data from the targeted base transceiver station and from a plurality of other base transceiver stations by way of a plurality of other network aggregation devices;
- detecting, for each probe packet of the plurality of probe packets, a response or a failure of the targeted base transceiver station and the network aggregation device to provide the expected reply as an indication of reachability;
- and
- determining a change in reachability of the targeted base transceiver station and the network aggregation device as an indication of a service impacted outage based on the indication of reachability,
- wherein the detecting of the change in reachability of the targeted base transceiver station and the network aggregation device comprises:
- determining a service impacted outage start time as a time instant of a first failure of the targeted base transceiver station and the network aggregation device to provide the expected reply after having previously replied;
- determining a service impacted outage end time as a time instant of a first reply of the targeted base transceiver station and the network aggregation device after having previously failed to reply;
- and
- calculating for each targeted base transceiver station and the network aggregation device a service impacted outage duration as a difference between the service impacted outage end time and the service impacted outage start time.

A method, comprising:
- directing, by a cell-site router comprising a processor, a plurality of probe packets to a base transceiver station, wherein each probe packet of the plurality of probe packets prompts a reply from the base transceiver station, wherein network traffic data is initiated from the base transceiver station;
- detecting, by the cell-site router, for each probe packet of the plurality of probe packets, a response or a failure of the base transceiver station to provide an expected reply as an indication of reachability;
- and
- detecting, by the cell-site router, a change in reachability of the base transceiver station as an indication of a service impacted outage, wherein the change in reachability is based on the indication of reachability, and wherein the change in reachability is recorded in outage log records, wherein the detecting of the change in reachability comprises:
- determining for the base transceiver station a service impacted outage start time as a time instant at which a failure to provide the reply first occurred after having previously replied;
- determining for the base transceiver station a service impacted outage end time as a time instant at which a reply first occurred after having previously failed to reply;
- and
- determining a service impacted outage duration as a difference between the service impacted outage end time and the service impacted outage start time.

A machine-readable storage device, comprising executable instructions that, when executed by a processor, facilitate performance of operations comprising:
- directing a set of probe packets to a network aggregation device that receives network traffic data from a base transceiver station, wherein the network aggregation device receives the set of probe packets and other sets of probe packets from a plurality of other network aggregation devices, wherein each probe packet of the set of probe packets and the other sets of probe packets prompts a reply from the network aggregation device;
- detecting, for each probe packet of the set of probe packets, a response or a failure of the network aggregation device to provide the reply as an indication of reachability;
- determining a change in reachability of the network aggregation device as an indication of a service impacted outage based on the indication of reachability;
- determining, for the network aggregation device, a service impacted outage start time as a time instant at which a failure to provide the reply first occurred after having previously replied;
- determining, for the network aggregation device, a service impacted outage end time as a time instant at which a reply first occurred after having previously failed to reply;
- and
- determining a service impacted outage duration as a difference between the service impacted outage end time and the service impacted outage start time.
