Geolocation data acquisition system

摘要

A geolocation data acquisition system (200) and method (400) for acquiring communication session data from a mobile radio communications network (210). A data extraction module (222, 226) extracts call session data continuously from a network of call processors (224, 228), each call processor supporting mobile communication units in an associated geographical region of the coverage area of the mobile radio communications network. The data extraction module (222, 226) provides the extracted data to one of several storage areas (260). In each storage area, a record is created of the communication session data for each call made within the coverage area of an associated set of call processors (224, 228). The records stored in each storage area (260) comprise the data available for all communication sessions in the geographical region associated with the corresponding set of call processors (224, 228).

1. A geolocation data acquisition system for communication session data from a mobile radio communications network, the mobile radio communications network comprising a network of call processors, each call processor supporting mobile communication units in an associated geographical region of the coverage area of the mobile radio communications network, comprising:
a data extraction module, operable to extract communication session data continuously from each call processor; the data extraction module being:
(i) operable to access communication session data for calls made within the coverage area of each call processor linked to the data extraction module; and(ii) further linked to a storage area associated with a set of the call processors and the data extraction module, the storage area adapted to store a record of the communication session data for each call made within the coverage area of the set of call processors; whereby the records stored in each storage area comprise the data available for all communication sessions in the geographical region associated with the corresponding set of call processors; wherein the geolocation data acquisition system further comprising:
a data loader associated with each storage area, the data loader operable to: process the communication session data stored within the respective storage area to identify a subset of communication session data and to provide geolocation information for each communication session record, the geolocation information being derived from measurement data for cells contained within the communication session data; and send the subset of communication session data and geolocation information for each communication session record to a geolocation storage area.
