System, method, and computer program for rerating customer events in parallel with executing one or more open sessions in a consumer telecommunication network

A method, comprising:

• determining, by a computer system, that a first billing plan associated with a telecommunications subscriber has changed to a second billing plan during a current billing cycle;
• responsive to determining that the first billing plan has changed to the second billing plan, identifying, by the computer system, accumulated events of the current billing cycle that were rated using the first billing plan;
• rerating, by the computer system, the identified accumulated events using the second billing plan;
• identifying, by the computer system, one or more resource allowances corresponding to the telecommunications subscriber;
• updating, by the computer system, one or more counters indicating an available portion of the one or more resource allowances corresponding to the telecommunications subscriber, based on the rerating of the accumulated events;
• identifying, by the computer system, one or more open sessions associated with the telecommunications subscriber being executed during the rerating and that have not yet been applied to the one or more counters;
• identifying, by the computer system, at least one existing reservation allocating a portion of the one or more resource allowances to the one or more open sessions;
• determining, by the computer system, that the portion of the one or more resource allowances allocated by the at least one existing reservation is more than the available portion of the one or more resource allowances indicated by the updated one or more counters, and accordingly that the at least one existing reservation requires modification as a result of updating the one or more counters associated with the one or more resource allowances;
• and
• responsive to determining that the at least one existing reservation requires modification, automatically requesting, by the computer system, authorization for at least one updated reservation that includes the required modification of the at least one existing reservation.

A system comprising:

• a memory of a computer system;
• and
• one or more processing cores of the computer system coupled to the memory system that are each configured to:
• determine that a first billing plan associated with a telecommunications subscriber has changed to a second billing plan during a current billing cycle;
• responsive to determining that the first billing plan has changed to the second billing plan, identify accumulated events of the current billing cycle that were rated using the first billing plan;
• rerate the identified accumulated events using the second billing plan;
• identify one or more resource allowances corresponding to the telecommunications subscriber;
• update one or more counters indicating an available portion of the one or more resource allowances corresponding to the telecommunications subscriber, based on the rerating of the accumulated events;
• identify one or more open sessions associated with the telecommunications subscriber being executed during the rerating and that have not yet been applied to the one or more counters;
• identify at least one existing reservation allocating a portion of the one or more resource allowances to the one or more open sessions;
• determine that the portion of the one or more resource allowances allocated by the at least one existing reservation is more than the available portion of the one or more resource allowances indicated by the updated one or more counters, and accordingly that the at least one existing reservation requires modification as a result of updating the one or more counters associated with the one or more resource allowances;
• and
• responsive to determining that the at least one existing reservation requires modification, automatically request authorization for at least one updated reservation that includes the required modification of the at least one existing reservation.
