Abstract

A data management system and method of managing call data for at least one radio network element within a cellular communication network. The method comprising receiving call data for at least one call from the at least one radio network element within the cellular communication network, arranging the received call data into call data records of a non-fixed size, and writing the call data records to at least one data storage device such that the call data records are stored adjacent one another.

Claims

1. A method of managing call data for at least one radio network element within a cellular communication network, the method comprising:

receiving call data for at least one call from the at least one radio network element within the cellular communication network;

arranging the received call data into call data records of a non-fixed size; and

writing the call data records to at least one data storage device such that the call data records are stored adjacent one another.

2. The method of claim 1, wherein the method comprises writing the call data records to the at least one data storage device such that the call data records are stored contiguously.

3. The method of claim 1, wherein the method comprises assembling the call data records into at least one data block, and writing the at least one data block to at least one data storage device,

wherein the method further comprises, upon receipt of a call data query, retrieving call data records from the at least one data storage device on a per data block basis.

4. The method of claim 3, wherein the method further comprises temporally grouping the call data records, and arranging temporally grouped call data records into data blocks.

5. The method of claim 1, wherein the method comprises arranging the call data for the at least one call into a plurality of call data records based at least partly on intra-call events.

6. The method of claim 5, wherein the at least one intra-call event comprises at least one from a group comprising at least one of:

an initiation of the at least one call;

a call data segmentation time period expires;

a generation of a measurement report;

a change of call service type.

7. The method of claim 5, wherein the call data is arranged into one call data record per intra-call event.

8. The method of claim 5, wherein the call data is chronologically divided between a plurality of call data records based at least partly on intra-call events occurring.

9. A data management system comprising at least one signal processing module arranged to:

receive call data for at least one call from the at least one radio network element within the cellular communication network;

arrange the received call data into call data records of a non-fixed size; and

write the call data records to at least one data storage device such that the call data records are stored adjacent one another.

10. A cellular communication system incorporating the data management system of claim 9.

11. A non-transitory computer program product having computer-readable code stored thereon for programming a signal processing module to perform a method of managing call data for at least one radio network element within a cellular communication network, the code operable for:

receiving call data for at least one call from the at least one radio network element within the cellular communication network;

arranging the received call data into call data records of a non-fixed size; and

writing the call data records to at least one data storage device such that the call data records are stored adjacent one another.

12. The non-transitory computer program product of claim 11, wherein the non-transitory computer program product comprises at least one of:

a hard disk, a CD-ROM, an optical storage device, a magnetic storage device, a Read Only Memory (ROM), a Programmable Read Only Memory (PROM), an Erasable Programmable Read Only Memory (EPROM), an Electrically Erasable Programmable Read Only Memory (EEPROM), and a Flash memory.
