Abstract

Methods, systems, and media for identifying areas of outbound roaming on a wireless network are disclosed. A roaming-network event record listing roaming events of subscribers of a home network is received. A home-network event record listing network events on a home network is also received. The two records are correlated to identify roaming events and network events having matching caller identifiers and time stamps within a predetermined range. Location data of a network event is adopted as location data for a matching roaming event. A home-network wireless-communications antenna, tower, or station having a service area in which a concentration of roaming events have occurred is identified. The distance of the roaming events from the antenna is determined and distance bands corresponding to that distance are plotted on a map to aid in identifying locations at which outbound roaming has occurred.

Claims (18)

1. Non-transitory computer-readable storage media having computer-executable instructions embodied thereon that, when executed, perform a method for associating location data with an outbound roaming call on a wireless network, the method comprising:

receiving a roaming-network event record comprising roaming data that describes a plurality of roaming events on a roaming network, the roaming data including a first caller identifier and a first time stamp for each roaming event in the plurality of roaming events;

correlating the roaming data with home-network data in a home-network event record, the home-network data describing a plurality of network events on a home network and including a second caller identifier, a second time stamp, and location data for each network event in the plurality of network events;

identifying one or more locatable roaming events in the plurality of roaming events;

determining location data for the one or more locatable roaming events based on the home-network data;

plotting the locatable roaming events on a map based on the location data adopted from the home-network event; and

identifying one or more of a home-network antenna that has a concentration of locatable roaming events within a service area thereof or a geographic location that includes a concentration of locatable roaming events.

2. The non-transitory computer-readable storage media of claim 1 , wherein correlating the roaming data with the home-network data further comprises:

identifying a roaming event in the roaming-network event record having a first caller identifier matching a second caller identifier of a network event in the home-network event record.

3. The non-transitory computer-readable storage media of claim 2 , wherein identifying one or more locatable roaming events in the plurality of roaming events further comprises:

determining that the first time stamp associated with the roaming event is within a predetermined range of the second time stamp associated with the network event in the home-network event record.

4. The non-transitory computer-readable storage media of claim 3 , wherein determining location data for the one or more locatable roaming events based on the home-network data further comprises:

adopting the location data of the network event in the home-network event record as location data for the locatable roaming event.

5. The non-transitory computer-readable storage media of claim 3 , wherein the predetermined range is set based on the average speed of travel of callers in an area including the service area of the identified home-network antenna.

6. The non-transitory computer-readable storage media of claim 1 , wherein the roaming-network event record and the home-network event record are one or more of a call detail record (CDR) and a per call measurement data (PCMD) record.

7. The non-transitory computer-readable storage media of claim 1 , wherein the first caller identifier and the second caller identifier are mobile directory numbers (MDN).

8. The non-transitory computer-readable storage media of claim 1 , wherein the location data for each network event includes an indication of one or more of a tower, a sector, an antenna, a distance from a tower or antenna, a longitude, a latitude, and a round trip delay measurement.

9. The non-transitory computer-readable storage media of claim 1 , wherein the first time stamp provided in the roaming-network event record and the second time stamp provided in the home-network event record include one or more of an event start time, an event end time, and an event duration.
