Title: Synchronization of stored service parameters in a communication system
Inventor: WANG JUN
IPC: H04J13/00
Filed: 2002-05-21
Abstract: Techniques for synchronization of stored service parameters are disclosed. I n one aspect, a configuration identifier is transmitted (370) from a mobile station (106) to a base station (104), and compared with an identifier generated in the base station (380). If the identifiers match, the configuration is used for communication (390). In another aspect, the identifier is generated by selecting an identifier associated with a configuration from a configuration table (610). In yet another aspect, the identifier is generated by computing a cyclic redundancy check (CRC) of the configuration (320). Various other aspects are also presented. These aspects have the benefit of preventing attempted use of unsynchronized stored servic e parameters and associated call setup failures and subsequent renegotiation, with the net effect of reducing call setup time and more efficient use of system resources.

Title: Usage-based billing for voice over packet communications
Inventor: JONES BRYCE A
IPC: H04M15/00
Filed: 2002-05-22
Abstract: A communication system (100) is disclosed that provides usage-based billing for voice communications transmitted over a packet system (106). The communication system is comprised of a packet billing system (104) that sniffs signaling transmitted between a signaling processor (102) and a communication device (112), such as a switch or a router. If the packet billing system detects a call setup message in the signaling, then the packet billing system generates a start record. If the packet billing system detects a call complete message in the signaling, then the packet billing system generates an end record. The packet billing system transfers the start record and the end record to a conventional public switched telephone network (PSTN) billing system (194). The PSTN billing system generates a bill for the call based on the start record and the end record. The communication system advantageously provides usage-based billing for packet-based calls using the conventional PSTN billing system.

Title: A non-contact auxiliary switch and electric power apparatus incorporating same
Inventor: MOLDOVAN PETER K
IPC: H01H71/04
Filed: 2003-12-19
Abstract: The auxiliary switch includes a non-contact sensor, such as a Hall effect device, that is switched by the condition of a magnetic field. The magnetic field condition is effected by a movable contact indicator that moves between open and closed positions with the separable contacts of the electric power apparatus. A magnet may be attached to the movable contact indicator, or the movable contact indicator can be magnetized to form the magnet. Alternatively, the moving contact indicator can intercept or not intercept a magnetic field produced by a fixed magnet spaced from the sensor. The Hall effect device may be mounted on the outside of the nonmagnetically permeable housing of the electric power apparatus, or inside if there is sufficient room. In either case, no mechanical coupling is required for the sensor.
