Methods and systems for charging deductions disregarding existing reservations utilizing priority resource buckets

A node in a telecommunication system for deducting resources from one or more resource buckets associated with a charge for a service used by a subscriber in the telecommunication system, the node comprising:

• a communication interface configured to receive a first message requesting a reservation of resources for the first service;
• a processor configured to reserve resources for the first service from one or more available resource buckets according to a priority order, the first service reserves resources from a first resource bucket;
• the communication interface configured to receive, after the reserving for the first service, a second message requesting a reservation of resources for a second service;
• the processor configured to reserve resources for the second service from one or more available resource buckets according to the priority order, the second service reserves resources from a second resource bucket;
• the communication interface configured to receive a message including a consumed amount of resources associated with the second service;
• and
• the processor configured to deduct the consumed amount of resources associated with the second service by taking units from the resources which were previously reserved for the first service, wherein units from a higher priority resource buckets are deducted for the second service, even the units are reserved for other service.

A non-transitory computer-readable storage medium containing a computer-readable code that when read by a processor causes the processor to perform a method for deducting resources from one or more resource buckets associated with a charge for a service used by a subscriber in a telecommunication system, the method comprising:

• receiving, at a node in the telecommunication system, a first message requesting a reservation of resources for the first service;
• reserving, at the node in the telecommunication system, resources for the first service from one or more available resource buckets according to a priority order, the first service reserves resources from a first resource bucket;
• receiving, at the node in the telecommunication system after the reserving for the first service, a second message requesting a reservation of resources for a second service;
• reserving, at the node in the telecommunication system, resources for the second service from one or more available resource buckets according to the priority order, the second service reserves resources from a second resource bucket;
• receiving, at the node in the telecommunication system, a message including a consumed amount of resources associated with the second service;
• and
• deducting, at the node in the telecommunication system, the consumed amount of resources associated with the second service by taking units from the resources which were previously reserved for the first service, wherein units from a higher priority resource buckets are deducted for the second service, even the units are reserved for other service.
