Abstract

Enforcing user-defined real-time communication session terminations can begin with a termination enforcement handler identifying termination conditions applicable to a real-time communication session hosted by a unified telephony system. The termination conditions can define a limit for an operational variable for the unified telephony system or the real-time communication session. The identified termination conditions can be evaluated. If a termination condition is satisfied, it can be determined which participants are to be disconnected from the real-time communication session based upon handling rules for the termination conditions and/or termination preferences associated with the real-time communication session. The termination preferences can be defined by an initiating entity of the real-time communication session. The participants can be notified that their connection to the real-time communication session will be terminated in a predefined time limit. If the predefined time limit is reached, the participants'"'"' connection to the real-time communication session can be automatically terminated.

Claims

1. A method comprising:

identifying of at least one termination condition applicable to a real-time communication session hosted by a unified telephony system by a termination enforcement handler, wherein the at least one termination condition defines a limit for an operational variable for at least one of the unified telephony system and the real-time communication session, wherein the operational variable comprises at least one of a quality of service level, a performance level of the unified telephony system, a bandwidth availability, a quantity of participants for the real-time communication session, a total quantity of real-time communication sessions in the unified telephony system, a total quantity of a specific type of real-time communication sessions, a server load, and a maintenance schedule for resources of the unified telephony system;

evaluating the at least one termination condition;

in response to at least one termination condition being satisfied, determining at least one participant of the real-time communication session to disconnect from the real-time communication session based upon at least one of handling rules associated with the at least one termination condition and termination preferences associated with the real-time communication session, wherein the termination preferences are defined by an initiating entity of the real-time communication session;

notifying the at least one participant of the real-time communication session of a termination of their connection to the real-time communication session in a predefined time limit, wherein notifying the at least one participant of termination further comprises;

generating a termination notification for the at least one participant;

determining a notification frequency for the termination notification to the at least one participant based upon at least one of handling rules and termination preferences;

initiating a termination timer expressing the predefined time limit; and

sending the termination notification to the at least one participant according to a time indicated on the termination timer and the notification frequency, wherein a format of the termination notification is based upon media types supported by the real-time communication session, handling rules, and termination preferences; and

in response to the predefined time limit being reached, automatically terminating the connection of the at least one participant to the real-time communication session.

2. The method of claim 1, wherein the evaluating of the at least one termination condition further comprises:

ascertaining a need for data from an auxiliary data system to represent the operational variable of a corresponding termination condition; and

requesting said data from the auxiliary data system for participants of the real-time communication session, wherein the data comprises at least one of calendar data, corporate directory data, personnel data, and project scheduling data.

3. The method of claim 1, wherein the handling rules represent one or more configurable options associated with the termination of the real time communication session.

4. The method of claim 1, wherein the determining at least one participant to disconnect further comprises:

ascertaining a need for data pertaining to participants of the real-time communication session from an auxiliary data system;

requesting said data from the auxiliary data system;

arranging a list of the participants in a termination order based upon the data received from the auxiliary data system and applicable handling rules and termination preferences, wherein the termination order expresses a preference in which the participants are to be terminated from the real-time communication session; and

selecting the at least one participant to disconnect from the arranged list according to the termination order.

5. The method of claim 4, wherein arranging of the list further comprises:

identifying participants immune to disconnection from the real-time communication session, wherein said immunity is defined in at least one of a handling rule or a termination preference; and

removing the identified participants from the list.

6. The method of claim 1, further comprising:

in response to the at least one termination condition being unsatisfied, monitoring a value of the operational variable of the at least one termination condition;

in response to a change in the value being detected, capturing the changed value; and

re-executing the evaluation of the at least one termination condition.

7. The method of claim 1, wherein, upon the initiating entity of the real-time communication session manually invoking termination of the at least one participant by the termination enforcement handler, said method further comprising:

determining a need for support from other participants of the real-time communication session to terminate at least one participant selected by the initiating entity from the real-time communication session, wherein the other participants excludes the at least one participant selected by the initiating entity;

upon a determination that support is needed, polling the other participants for their support;

analyzing results of the polling; and

in response to the results of the polling indicating support for termination of the at least one participant selected by the initiating entity, executing the notification and termination of the at least one selected participant.

8. The method of claim 7, further comprising:

in response to the results of the polling being to reject termination of the at least one selected participant, informing the initiating entity of said rejection.

9. The method of claim 1, further comprising:

checking calendar information of participants of the real time communication session;

determining, based on the calendar information, whether a scheduled event exists for a participant of the real time communication session;

identifying other participants of the real time communication session affected by the scheduled event; and

terminating the identified participants from the real time communication session when the real time communication session is still active at a predetermined time before the start of the scheduled event, wherein the real time communication session is terminated based upon handling rules and termination preferences, wherein participants affected by termination are provided a predetermined amount of time prior to being terminated.

10. The method of claim 9, further comprising performing a recheck of the calendar information at a later time if no scheduled event exists for the participant of the real time communication session, wherein the recheck is performed only if the real time communication session is active at the later time.

11. The method of claim 9, further comprising ceasing termination of the real time communication session if the affected participants are not connected to the real time communication session.

12. The method of claim 1, further comprising:

detecting an operating condition of the unified telephony system requiring a quantity of participants of the real time communication session to be reduced;

ascertaining handling rules and termination preferences applicable to the detected operating condition;

compiling a list of participants of a plurality of real time communication sessions of the unified telephony system;

arranging the list of participants according to a corporate hierarchy based on a comparison of the list of participants with a corporate directory;
