METHOD AND APPARATUS FOR MAINTAINING NETWORK PERFORMANCE IN A COMMUNICATION SYSTEM
First Claim
1. A network management system (NMS) that manages operations of a communication system including a mobile telephone switching office (MTSO) coupled to a plurality of wireless base terminals (WBTs) by way of a corresponding plurality of network elements, comprising a network configuration element that identifies for each of the plurality of WBTs a plurality of resultant communication paths to the MTSO according to a plurality of differential delays calculated from alternative communication paths connecting combinations of the WBTs to the MTSO for each of a plurality of change scenarios affecting the plurality of network elements, wherein a change scenario comprises at least one of a failure occurring at one or more of the plurality of network elements and a failure in a link between two or more of the plurality of network elements.

Abstract
A method and apparatus is disclosed for method and apparatus for maintaining network performance in a communication system. A system that incorporates teachings of the present disclosure may include, for example, a network management server (NMS) that manages operations of a communication system including an access office (AO) coupled to a plurality of base terminals (BTs) by way of a corresponding plurality of network elements. The NMS can have a network configuration element that identifies for each of the plurality of BTs a plurality of resultant communication paths to the AO according to a plurality of differential delays calculated from alternative communication paths connecting combinations of the BTs to the AO for each of a plurality of change scenarios affecting the plurality of network elements, wherein the network configuration element arranges portions of the plurality of BTs into a corresponding plurality of groups, and selects for each BT in a select one of the plurality of groups its corresponding plurality of resultant communication paths to the AO according to differential delays calculated for alternative communication paths associated with combinations of BTs in the selected group and the plurality of change scenarios affecting the selected group. Additional embodiments are disclosed.
