Abstract: A method for directing inquiries to available subject matter experts includes storing an expert database in memory and defining presence states to describe present attributes of each subject matter expert with respect to a number of resource elements. Inquiries are directed to the experts, and response histograms are populated based on whether a response was obtained in a given presence state. The response histograms describe or define a response probability for each subject matter expert, as a function of the corresponding present attributes for each of the resource elements.

Abstract: A method for providing telecommunications users access to information networks. This is achieved by providing access information for at least one service provider to a service application. Thereafter, the service application retrieves the access information when information is requested from the service provider. The service application formats a request with the access information and transmits the request to the service provider. The service provider's response is presented to the user. By the use of this invention, the user can request information from a service provider from one or more devices without re-entering the access information.

Abstract: A method and apparatus for updating information in a personal mobility database server with information concerning a user's nomadicity. When the user travels from one place to another, the user registers with PMDNS server at an IP port for computing communications. PMDNS takes user's terminal personalization, together with usage profile, session characteristics into account to map a party's identifier to a terminal's identifier. The IP address of the user's current location is used in concert with the terminal's identifier, which is itself an IP address, to route incoming computing communications connection requests to the current location of the user. This information will be returned by the PMDNS directory server to the access network for the setup of the communications.

Abstract: A method for providing information to devices in a format preferable to a device type. This is achieved by receiving an information request, detecting the device type from which the information request originated, adapting the content for presentation on the device type, and presenting the information to the device. By the use of this invention, telecommunications users are presented information in a format suitable to the device being used.

Abstract: A system for proactive maintenance of a telecommunications network. A database is created containing characteristics of a plurality of valid logs. These valid logs represent alarms within a network which report status and abnormalities in the network and which have been specifically selected by a network domain expert or administrator from a larger group of logs. The characteristics correspond to a pattern of network fault parameters. The network is monitored for occurrences of a valid log. When a valid log is encountered, future occurrence of a fault is predicted based on an analysis of the valid log and the characteristics found in the database. Corrective measures are taken to prevent the fault from occurring.

Abstract: The invention overcomes the inefficient conventional mobile paging methods that cause a bottleneck in the FOCC due to constraints of both the bandwidth and the limited number of radio frequency channels in mobile telecommunication systems. This is accomplished by first determining the mobility pattern of each mobile station during a given sampling period. Then the probability that the mobile station will be located within each cell in the network is determined. From the cells having non-zero probabilities, at least two paging zones are defined using a genetic optimization method which converges on paging zones which produce a minimum paging cost which correspondingly results in minimum utilization of the FOCC.

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 method for distributing paging load in a multicell wireless communication system establishes a plurality of location areas, with each location area including at least one cell. A load limit is based upon the greatest number of pages that may be transmitted in a particular cell over a given time period for cells of the multicell wireless communication system is determined. A paging load for the cellular wireless communication system is determined based upon historical loading and/or simulations and projections. A plurality of location areas are determined so that the paging load is distributed among the plurality of location areas such that a partial paging load respective to each cell of the multicell wireless communication system is less than a respective load limit. Boundaries of the location areas are then chosen to substantially minimize registration load within the multicell wireless communication system.

Abstract: A method for reducing the paging load in a cellular communication system is described. The cell C with the largest paging load L is first identified. Since this cell is usually included in more than one paging zone, the paging zones including cell C are identified. Thereafter, cell C is removed tentatively from each identified zone and a ratio R calculated which represents the decrease in loading on cell C due to being removed from zone z divided by the maximum increase in loading on any other cell in the network. The zone for which the ratio R is the largest is the best candidate for removing cell C therefrom. After doing so tentatively, the cell C' with the largest paging load L' thereon is identified. If the loading L is greater than L', cell G is removed permanently from the zone having the highest ratio R therefor and the process is repeated until L' is greater than L at which point the process is stopped without removing cell C from the zone with the highest ratio R.

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.
