A mobile communication system for matching resource amount of core network bearer and resource amount of visited network bearer

摘要

A visited policy controlling device decides the amount of a visited network bearer resource that is provided by a visited user plane device for an end-to-end service based on the amount of a bearer service resource requested to be used in the end-to-end service. A home policy controlling device decides the amount of a core network bearer resource that a home gateway device provides for the end-to-end service based on the amount of the bearer service resource requested to be used in the end-to-end service. Further, a home policy controlling device performs processing to match the amount of the core network bearer resource decided by itself and the amount of the visited network bearer resource decided by visited policy controlling device, if they do not match.
