Parameter reconfiguration of connected calls
First Claim
1. A method of determining whether a requested reconfiguration of call parameters to a provisioned and connected call in a switched digital communications network complies with service parameters negotiated for said provisioned and connected call comprising:
- a) calculating a differential between existing call parameters for the provisioned and connected call and call parameters for the requested reconfigured call;
b) determining whether parameters for said requested reconfigured call fall within network parameter ranges;
c) determining whether the calculated differential between existing call parameters for the provisioned and connected call and call parameters for the requested reconfigured call is less than parameters provisioned for the communications; and
determining that said requested reconfiguration complies with service parameters of said network if conditions b) and c) are satisfied.

Abstract
A method of determining whether a requested parameter reconfiguration of a connected call in a switched digital communication network complies with system constraints is described. Bandwidth related parameters, in particular, are subject to reconfiguration after a call is provisioned in order to optimize utilization of network resources. The implementation of a bandwidth reconfiguration involves an assessment of bandwidth utilization by the logical or physical links routing the connected call so that the reconfigured bandwidth does not negatively impact on the connected call. Once the reconfigured parameter is determined to be acceptable the reconfiguration data is propagated to the relevant network elements.

13. A method of reconfiguring an existing connected call in a switched digital communications network to improve utilization of network bandwidth comprising:
-
a) calculating a bandwidth differential by subtracting bandwidth utilization of the existing connected call from bandwidth to be used by the reconfigured call;
b) determining whether bandwidth to be used by the reconfigured call is greater than or equal to a minimum bandwidth permitted on a link used by the reconfigured call;
c) determining whether bandwidth to be used by the reconfigured call is les than or equal to a maximum bandwidth permitted on said link;
d) determining whether available bandwidth on said link is greater than said bandwidth differential and e) rejecting a request to reconfigure said existing call if the conditions in steps b), c) or d) are not satisfied otherwise forwarding said request to network elements in said communications network. - View Dependent Claims (14, 15)

16. A method of reconfiguring an existing logical link in a switched digital communications network to improve utilization of network bandwidth comprising:
-
a) calculating total bandwidth utilization for all calls on said logical link;
b) determining whether bandwidth utilization of a reconfigured logical link is less than said total bandwidth utilization and if so reject reconfiguration of said logical link, otherwise c) calculating a bandwidth differential by subtracting bandwidth utilization of the existing logical link from bandwidth to be used by the reconfigured logical link;
d) determining whether bandwidth to be used by the reconfigured logical link is greater than or equal to a minimum bandwidth permitted on a physical link used by the reconfigured logical link;
e) determining whether bandwidth to be used by the reconfigured logical link is less than or equal to a maximum bandwidth permitted on said physical link;
f) determining whether available bandwidth on said physical link is greater than said bandwidth differential and g) rejecting a request to reconfigure said existing logical link if the conditions in steps b), c) or d) are not satisfied otherwise forwarding said request to network elements in said communications network. - View Dependent Claims (17, 18)
