Abstract

A system and method are provided for enabling additional capacity or features on telecommunication nodes without requiring replacement of hardware. Service providers purchase hardware which is fully capable of providing a full suite of features and providing a large bandwidth capacity. However, depending on the amount of payment by the service provider, not all of the features or the bandwidth capacity is enabled. If the service provider wishes to increase the number of features or the capacity of a node, the additional features or capacity are enabled using software after payment to the vendor. This allows service providers to enter the market at an initially relatively low expense. Additional features and capacity can be purchased and enabled using software as demand grows, without having to purchase replacement hardware.

Claims

1. A method of enabling capabilities on a telecommunication node having a control complex, the method comprising the steps of:

associating in memory of the control complex an enabled status of each capability;

enforcing the enabled status of each capability by limiting operator access to configuration only of those capabilities which are enabled;

in response to instructions from an operator, enabling a specified capability by adjusting the enabled status of the specified capability; and

calculating a charge for enabling the specified capability.

2. The method of claim 1 wherein the step of calculating a charge comprises retrieving a charge stored in memory and associated with the specified capability.

3. The method of claim 1 comprising the further step of specifying a duration for which the specified capability is to be enabled, and wherein the step of calculating a charge comprises calculating a charge associated with the specified capability and the specified duration.

5. The method of claim 3 wherein the step of calculating a charge comprises retrieving a charge stored in memory and associated with the specified capability and the specified duration.

6. The method of claim 1 further comprising the steps of:

for each capability, storing a first corresponding security key in memory; and

for each capability, storing a second corresponding security key in memory of the control complex, the second security key being correlatable on a one-to-one basis with the first security key corresponding to the capability;

and wherein the step of enabling a specified capability comprises;

transmitting the first security key corresponding to the specified capability to the control complex;

at the control complex, determining whether a second security key stored in memory of the control complex is related to the first security key transmitted to the control complex; and

if such a second security key is found, enabling the capability corresponding to the second security key by adjusting the enabled status of the capability.

7. The method of claim 6 wherein the step of storing a first corresponding security key comprises storing the first corresponding security key in memory of a network manager separate from the telecommunication node.

13. The method of claim 12 wherein the step of calculating a charge comprises calculating a charge associated with the specified capability and with the specified duration.

14. The method of claim 13 wherein the step of calculating a charge comprises retrieving a charge stored in memory and associated with the specified capability and with the specified duration.

15. The method of claim 13 comprising the further steps of:

for each combination of capability and associated duration, storing a first corresponding security key in memory; and

for each combination of capability and associated duration, storing a second corresponding security key in memory of the control complex, the second security key being correlatable on a one-to-one basis with the first security key corresponding to the combination of capability and associated duration;

and wherein the step of enabling a specified capability comprises;

transmitting the first security key corresponding to the specified capability and the specified duration to the control complex;

at the control complex, determining whether a second security key stored in memory of the control complex is related to the first security key transmitted to the control complex; and

if such a second security key is found, enabling the capability corresponding to the second security key by adjusting the enabled status of the capability for the duration corresponding to the second security key.

16. The method of claim 15 wherein storing a first corresponding security key comprises storing the first corresponding security key in memory of a network manager separate from the telecommunication node.

17. The method of claim 16 wherein the step of calculating a charge comprises retrieving a charge stored in memory and associated with the specified capability and the specified duration.

18. The method of claim 16 wherein the telecommunication node is under administrative control of a service provider, wherein each first security key is stored in memory inaccessible to the service provider, and the method comprising the further step of:

retrieving the first security key corresponding to the specified capability from memory; and

transmitting the first security key corresponding to the specified capability to the service provider.

19. The method of claim 18 wherein each first security key is stored in memory under administrative control of a vendor, and the method comprising the further step of:

arranging payment of the charge from the service provider to the vendor before transmitting the first security key to the service provider.

20. The method of claim 1 comprising the further steps of:

storing a representation of available credits;

deducting the charge from the available credits.

21. The method of claim 20 wherein the representation of available credits is encrypted, and wherein the method comprises the further steps of:

storing at least one first credits security key in memory, each first credits security key corresponding to a respective credit augmentation amount;

providing a second credits security key;

determining whether one of the at least one first credits security key is related to the second credits security key on a one-to-one basis; and

if such a first credits security key is found, augmenting the stored available credits by the credit augmentation amount corresponding to the first credits security key.

22. The method of claim 21 wherein storing a representation of available credits comprises storing the representation of available credits in memory of a network manager separate from the telecommunication node, and wherein storing at least one first credits security key comprises storing at least one first credits security key in memory of the network manager.
