| 20110143760 | Modified Overhead Adjustment Function - A MOAF algorithm is used to resize cells for balancing capacity. The MOAF algorithm bases its decision on a cell and all other cells which the algorithm decides are sufficiently close in a propagation sense to affect the results.

All requirements are modeled as constraints and a constraint solver does the resolution Not every constraint to be solved is solved by the model-finder. Instead, we “factor away” subsets of a constraint that can be efficiently solved via a special-purpose constraint solver, such as an SQL/Prolog engine, linear programming system, or even an algorithm, leaving behind a constraint that truly requires the power of model-finding, and that is often efficiently solvable by existing model-finders.

| 20090029651 | Method and Procedures for Automatic Calibration of a Wireless Communications System Simulation - Performance optimization of mobile wireless communication networks is complex and typically requires extensive offline modeling and simulation prior to deploying changes that may have unforeseen adverse effects on the live customer network. It is necessary to calibrate the simulation model against the actual network at a level of fidelity such that the engineer is confident that the simulation's response to network changes accurately reflects the results that would be experienced if those changes were deployed in an actual live network. This process is typically quite time consuming and requires significant case-by-case insight into the workings of the actual network as well as the simulation model.

For a given network architecture and a probabilistic customer usage profile a simulation provides an estimate of key performance metrics.

| 20090016286 | ARCHITECTURE FOR MULTIPLE MIH USERS - Currently, the I.E.E.E. 802.21 specification allows multiple MIH (Media-Independent Handover) Users in a single MIH Function.

This document proposes a detailed architecture which allows for the co-existence of multiple MIH Users by introducing a link ownership scheme in the MIHF (MIH Function). The proposed link ownership scheme also supports the scenario in which the state of a link of a mobile node is changed by a network node by modifying the MIH_Register primitives in the I.E.E.E. 802.21 specification to signal the set of allocated links to a remote MIH User on the network node. The modification of MIH_Register primitive also has the added benefit of allowing the network node to subscribe to events on a specific set of links present in the mobile node as opposed to not knowing any of the links at all. | 01-15-2009 |

Validation can comprise checking expired certificates against misused, compromised and/or previously surrendered certificates. Time-distributed certificates can have lifetimes adjustable based on certificate misuse detection system algorithms, amount of malicious activity detected, and/or certificate authority capacity. | 09-25-2008 |
| 20080232583 | Vehicle Segment Certificate Management Using Shared Certificate Schemes - The present invention advantageously provides techniques to solve problems with combinatorial anonymous certificate management by addressing critical issues concerning its feasibility, scalability, and performance. Methods and procedures to manage IEEE 1609.2 anonymous and identifying cryptographic keys and certificates in the Vehicle Infrastructure Integration (VII) system are presented, along with methods for management of identifying and anonymous certificates in a partitioned Certificate Authority architecture designed to enhance vehicle privacy. Novel methods for vehicles to dynamically change an anonymous certificate for use while maintaining vehicle privacy are given. Refinements to basic combinatorial schemes are presented including probabilistic key replacement, rekey counter decrement, dynamic rekey threshold, geographic attack isolation and proofs of geographic position. | 09-25-2008 |
| 20080212783 | KERBERIZED HANDOVER KEYING IMPROVEMENTS - A media-independent handover key management architecture is disclosed that uses Kerberos for secure key distribution among a server, an authenticator, and a mobile node. In the preferred embodiments, signaling for key distribution is based on re-keying and is decoupled from re-authentication that requires EAP (Extensible Authentication Protocol) and AAA (Authentication, Authorization and Accounting) signaling similar to initial network access authentication. In this framework, the mobile node is able to obtain master session keys required for dynamically establishing the security associations with a set of authenticators without communicating with them before handover. By separating re-key operation from re-authentication, the proposed architecture is more optimized for a proactive mode of operation. It can also be optimized for reactive mode of operation by reversing the key distribution roles between the mobile node and the target access node. | 09-04-2008 |
