Patent ID: 8665737

Claim:
A method for controlling perceived quality of service (QoS), the method comprising: monitoring information streams of a conversation for at least one interactivity property describing how those information streams dynamically relate to one another, each of said streams originating from a different participant of the conversation; detecting occurrences characteristic of the at least one interactivity property associated with the information streams of the conversation, the detected occurrences indicating a level of conversational interactivity between different participants of the conversation; setting a maximum end-to-end (E2E) delay time duration for the information streams of the conversation based on the level of said conversational interactivity indicated by the detected occurrences, by setting the maximum E2E delay time duration to a relatively higher value when the detected occurrences indicate a relatively lower level of said conversational interactivity and to a relatively lower value when the detected occurrences indicate a relatively higher level of said conversational interactivity; and determining whether to allocate an amount of the maximum E2E delay time duration to perform at least one QoS application on the information streams of the conversation, based on whether an E2E delay time duration measured for the information streams of the conversation is below the maximum E2E delay time duration.
