International Classification:

H04M 1500

US Classification:

379119

Abstract:

A computer platform with a Call Billing application thereon monitors linksets of the CCS/SS7 network extending between Local Exchange Carrier (LEC) Signaling Transfer Points (STP) and Competitive Access Provider (CAP) switches such as End Offices (EO) and Tandem Offices, where the CAP switches have access to the LEC switching offices in the LEC area for providing service therein. The platform receives SS7 Signal Units (SU) copied from the linksets and filters the SUs to pass ISUP MSUs of message types Initial Address Message (IAM), Exit Message (EXM), Address Complete Message (ACM), Answer Message (ANM), Reset Circuit Message (RSC) and Release Message (REL). The application correlates a received IAM against subsequently received and filtered ISUP messages in accordance with correlation search keys Originating Point Code (OPC), Destination Point Code (DPC) and Circuit Identification Code (CIC) so as to correlate the filtered ISUP MSUs that originate, set up and terminate a call. The elapsed time of the call is determined based on the difference between a call start time and a call end time where the start time is predicated on a call originating or setup MSU and the end time is predicated on a call terminating MSU. The call type can be for either "access" or "conversation" elapsed time depending on call direction and destination.

Abstract:

Apparatus and method are provided for synchronized multiple vital health measurements. In one novel aspect, an integrated wearable device with multiple sensors that can collect multiple vital health signals, digitize them, send them through wireless network to a receiver. In one embodiment, the wearable device has a plurality of different types of sensors including at least one or more acoustic-to-electric sensors collecting phonocardiogram (PCG) electrical signal and one or more electrocardiogram (ECG) sensors, a control module includes a synchronization circuitry that synchronizes measurements of the plurality of different types of sensors. In another novel aspect, a system performs a synchronized measurement using a plurality type of health-monitoring sensors, performs a correlation analysis of the plurality of measurement results using selected one or more analytical rules, and obtains a set of parameters with recognized medical values and generating one or more medical health records based on the correlation analysis.
