Abstract: A personal mobility system determines a terminal address corresponding to a called user based upon a personal identifier of the called user. The personal mobility system operates in conjunction with a plurality of heterogeneous networks to provide the terminal address corresponding to the called user, independent of the particular network within which the called user currently operates. The personal mobility system includes a personal mobility user application and a personal mobility server application. The personal mobility user application receives a request from a calling user, the request including the personal identifier of a called user. The personal mobility server application couples to the personal mobility user application and includes a plurality of user records. Each user record is respective to a user and is indexed by a respective personal identifier. Further, each user record includes a plurality of terminal records with each of the terminal records including a respective terminal address.

Abstract: A self engineering system includes a data acquisition module, a self engineering engine, and a control module. The data acquisition module couples to the communication system and receives current operating data of the communication system. The self engineering engine receives the current operating data and determines new operating parameters of the communication system based upon the current operating data and current operating parameters. The control module implements the new operating parameters within the communication system. The self engineering system may include an expert system that receives the current operating data and, based upon the current operating data and the current operating parameters of the communication system, produces the new operating parameters. The expert system includes a fact library, a knowledge base and an inference engine. The fact library includes configuration data, historical operating data, the current operating parameters and proposed operating parameters.

Abstract: A data processing system implements a load balancing methodology which recognizes the effects that multiple, mobile subscribers have within a wireless communications network. During execution of this load balancing methodology, a rehoming operation is executed at a telephone central office to move some subscribers in a network to a new home mobile switching center with a minimum number of rehoming steps. To perform this rehoming operation, a mobile switching center in a network which has a highest load is selected first. Mobile switching centers which have a load lower than a network average load are considered to be candidates for a rehome destination. All subscriber groups homed to the highest loaded mobile switching center are evaluated to determine whether or not a rehoming operation using this subscriber group would provide a highest benefit and give a lowest standard deviation of loads among mobile switching centers after the rehome operation is selected.
