Abstract

A system and method of dynamically allocating memory records to a plurality of blocks in a telecommunications switch. A data acquisition monitor is provided for monitoring one or more traffic pattern parameters associated with the call traffic through the telecommunications switch. An analyzer analyzes the traffic pattern information and maintains traffic parameter profiles in a suitable database. Also, the analyzer determines if there exists a change in demand of service based on the monitored traffic pattern parameters. A command generator provides a feedback signal to the telecommunications switch to re-assign memory records based on the changes in demand of service.

Claims

1. A resource allocation method for use with a telecommunications switch wherein call traffic is handled via a plurality of blocks, comprising the steps of:

initially assigning a plurality of memory records to each of the blocks;

monitoring one or more traffic pattern parameters associated with the call traffic;

analyzing the traffic pattern parameters and computing changes in demand of service associated with the blocks; and

dynamically re-assigning the memory records to the blocks based upon the changes in demand of service.

2. The resource allocation method as set forth in claim 1, wherein each block is initially assigned an equal number of memory records.

3. The resource allocation method as set forth in claim 1, wherein each block is initially assigned a different number of memory records.

4. The resource allocation method as set forth in claim 1, wherein the traffic pattern parameters monitored comprises one or more short-term parameters.

5. The resource allocation method as set forth in claim 1, wherein the plurality of memory blocks initially assigned to a block represents the block'"'"'s initial Size Alteration Event.

6. The resource allocation method as set forth in claim 1, wherein the traffic pattern parameters monitored comprises one or more long-term parameters.

7. The resource allocation method as set forth in claim 1, wherein the initial assignment of memory records is based on the call traffic'"'"'s prior history.

8. The resource allocation method as set forth in claim 7, wherein the call traffic'"'"'s prior history comprises a set of data gathered on the traffic pattern parameters over a selected period of time.

9. The resource allocation method as set forth in claim 8, wherein the selected period of time comprises a week.

12. The resource allocation method as set forth in claim 1, wherein the traffic pattern parameters comprise short-term parameters.

13. The resource allocation method as set forth in claim 1, wherein the traffic pattern parameters comprise long-term parameters.

14. The resource allocation method as set forth in claim 1, wherein the analyzer computes the demand of service based on the block'"'"'s type.

10. A resource allocation system for use with a telecommunications switch wherein call traffic is handled via a plurality of blocks and each block is initially assigned a number of memory records, comprising:

a monitor for gathering data on one or more traffic pattern parameters associated with the call traffic;

an analyzer coupled to the monitor, the analyzer for analyzing the gathered data and maintaining a statistical database profile with respect to the traffic pattern parameters, wherein the analyzer computes a demand of service for each of the blocks based on the traffic pattern parameters; and

a command generator coupled to the analyzer, wherein the command generator provides one or more commands to the telecommunications switch responsive to an indication of a change in the demand of service received from the analyzer, the commands operating to effectuate a change in the number of records assigned to the blocks corresponding to the change in the demand of service.

11. The resource allocation system as set forth in claim 10, wherein the monitor is coupled to the telecommunications switch via a real-time data acquisition interface.

15. A dynamic resource allocation system, comprising;

means for monitoring a plurality of traffic pattern parameters associated with call traffic through a telecommunication switch, wherein the call traffic is handled through a plurality of blocks, each block having a number of records;

means for analyzing the traffic pattern parameters and determining a change in demand of service associated with the blocks; and

means for generating a record re-order command responsive to an indication provided by the analyzer corresponding to the change in demand of service, wherein the record re-order command is provided to the telecommunications switch to change the number of records assigned to the blocks.

16. The dynamic resource allocation system as set forth in claim 15, wherein the telecommunications switch comprises a cellular telecommunications switch.
