摘要:
Communication session data from a mobile radio communications network (100) is processed to extract substantially all communication session data relating to calls in at least two sectors of the network. This processing occurs as the communication session data becomes available, thereby providing a stream of communication session data (210). From the stream of communication session data (210), a high priority data stream (220) is created. The high priority data steam (220) comprises a minority of the communication session data for each call in the at least two sectors of the network (100). Geolocation data (230) is produced for each call. An immediately accessible copy of both the high priority data stream (220) and the geolocation data (230) is provided, for each call.
摘要:
A modular data processing system (200) for processing communication session data from a cellular mobile communications system (210) comprises at least two autonomous data processing units (340 ). The autonomous data processing units (340 ) are arranged in parallel, and are operable simultaneously. Each data processing unit (340) receives and processes raw communication session data from an associated set of controllers of the cellular mobile communications system (210). At least one data collection subsystem (215) supplies the raw communication session data to the at least two autonomous data processing units (340), for calls made within the coverage area of the set of controllers associated with the data processing unit. Processed data may be available more rapidly with the invention. The invention is scalable, and the system may expand as a cellular mobile communications system grows.

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).
摘要:
A system (200) and method (500) are provided for storing communication session data and geolocation information derived from a wireless mobile communications system (210). A record of data for each communication session taking place in at least one geographical region of the mobile radio communications network (210) is stored (510) in a first storage area (220). Each record of data is accessed (520), and a subset of the data for each communication session is stored (530) in a second storage area (250). Geo-location information is derived (540) for each communication session, and stored in the second storage area (250) The method and system may allow much more rapid access to subsets of data, and if necessary to the original records.

摘要:
A femto cell is located within a macro cell of a wireless communication system. A method of identifying the femto cell comprises: determining at least one timing difference, the at least one timing difference being observed for communications between a wireless communication unit and each of a femto cell and at least one macro cell; and comparing the at least one observed timing difference to reference timing difference data. The identity of the femto cell may allow the location of the femto cell to be set as a geographical location for a wireless communication device that is within the footprint of the femto cell. The identity of the femto cell may allow hand in of an ongoing call, from the macro cell to the femto cell.
摘要:
The invention relates to an asynchronous wireless communication system, such as a UMTS system. The various base stations of an asynchronous wireless communication system do not typically have known timing offsets Tb(i), and these timing offsets vary with time. The invention allows the calculation of the difference dTb(i,j) between timing offsets Tb(i), Tb(j) for pairs of base stations B(i), B(j), using the timing of signals received by one or more wireless communication units. Having eliminated the timing offsets between the base stations as a variable, geo-location techniques from synchronous networks may then be used to locate wireless communication units in the asynchronous wireless communication system.
