Abstract: What is provided is a system, method, and article of manufacture for detecting, monitoring, and tracking whether a user is in a more relaxed or stressed state by measuring the user's heart rate variability. The system has a heart rate monitoring device with at least one sensor that is configured to measure user heart rate. The system also has a mobile computing device, which may be configured to interact with the heart rate monitoring device for monitoring, tracking, and displaying a user's heart rate and mental stress level information. The method measures the user's heart rate information to calculate a measure of heart rate variability and to analyze whether peaks corresponding to activation levels of the user's parasympathetic nervous system (PNS) and sympathetic nervous system (SNS) exceed a predetermined threshold level within a predetermined time period.

Abstract: Telephone tones such as dialing tones and busy or engaged tones differ in different countries and in traditional telephone networks it has been possible to deal with this because national telephone networks have been used. However, with the advent of next generation communications networks in which telephone services are transmitted over a packet network, a need has arisen to manage telephone tones in a more sophisticated manner. To address this, a tone service provides telephone tone information to tone recipients such as media gateways, session initiation protocol (SIP) phones and virtual media gateways. In the event that a new tone recipient is added to the packet network, the tone service is able to automatically provide appropriate telephone tone information to that new tone recipient. Similarly, if telephone tones need to be upgraded or rolled back, the tone service is able to automatically provide appropriate telephone tone information to each of the tone recipients.

Abstract: A method of adapting the characteristics of a call server to optimise the call server's performance and usage of available network resources. A network management element determines the impact of any changes in the condition of the network on the call server and provides an indication to the call server which resets at least one characteristic of the call server to optimise the call server's performance.
