Mobile communication system for matching resource amount of core network bearer and resource amount of visited network bearer
First Claim
1. A mobile communication system in which a visited network and a home network are connected with each other via a core network, comprising:
- a visited user plane device provided on the visited network, connected with a mobile terminal, providing a visited network bearer resource for an end-to-end service that goes through the visited network, the core network and the home network between the mobile terminal and a counterpart side device, and relaying data of the end-to-end service by the visited network bearer resource;
a home gateway device provided on the home network, connected with the mobile terminal via the core network and the visited user plane device on the visited network, providing a core network bearer resource for the end-to-end service, and relaying data of the end-to-end service by the core network bearer resource;
a visited policy controlling device provided on the visited network, and deciding the amount of the visited network bearer resource that is provided by the visited user plane device for the end-to-end service based on the amount of bearer service resource required for using in the end-to-end service; and
a home policy controlling device provided on the home network, and deciding the amount of the core network bearer resource that is provided by the home gateway device for the end-to-end service based on the amount of the bearer service resource required for using in the end-to-end service, and performing 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 the visited policy controlling device, if they do not match.

Abstract
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.

8. A bearer resource controlling method in a mobile communication system in which a visited network comprising a visited user plane controlling device and a visited policy controlling device and a home network comprising a home gateway device and a home policy controlling device are connected via a core network, and the visited user plane device connects with a mobile terminal, provides a visited network bearer resource for an end-to-end service that goes through the visited network, the core network and the home network between the mobile terminal and a counterpart side device, and relays data of the end-to-end service by the visited network bearer resource, and the home gateway device connects with the mobile terminal via the core network and the visited user plane device in the visited network, provides the core network bearer resource to the end-to-end service, and relays data of the end-to-end service by the core network bearer resource, comprising;
-
deciding, in the visited policy controlling device, the amount of the visited network bearer resource that is provided by the visited user plane device 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; deciding, in the home policy controlling device, the amount of the core network bearer resource that is provided by the home gateway device for the end-to-end service based on the amount of bearer service resource requested to be used in the end-to-end service; and if the amount of the core network bearer resource decided by the home policy controlling device and the amount of the visited network bearer resource decided by the visited policy controlling device do not match, performing a process for matching them. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A home policy controlling device in a mobile communication system in which a visited network comprising a visited user plane controlling device and a visited policy controlling device and a home network comprising a home gateway device and a home policy controlling device are connected via a core network, and the visited user plane device connects with a mobile terminal, provides a visited bearer resource for an end-to-end service that goes through the visited network, the core network and the home network between the mobile terminal and a counterpart side device, and relays data of the end-to-end service by the visited network bearer resource, and the home gateway device connects with the mobile terminal via the core network and the visited user plane device in the visited network, provides the core network bearer resource to the end-to-end service, and relays data of the end-to-end service by the core network bearer resource;
-
wherein the visited policy controlling device is caused to decide the amount of the visited network bearer resource that is provided 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, and the home policy controlling device decides by itself the amount of the core network bearer resource that is provided by the home gateway device 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; and if the amount of the core network bearer resource decided by itself and the amount of the visited network bearer resource decided by the visited policy controlling device do not match, processing for matching them is performed.
