1. A resource control method, comprising:
- receiving from User Equipment (UE) currently associated with a network a resource request message configured for accessing multiple networks using a same Access Point Name (APN)determining another network suitable for the UE according to resource information specified in said request, andnotifying information about the determined another network to the UE,said notifying comprises;
determining that a network-side device refuses to accept the resource request message sent by the UE in the current network,in response to said refusal, sending, by a Policy and Charging Rule Function (PCRF), an identifier (ID) of a network recommended or specified by the PCRF for the UE to use to a gateway device; and
forming a Bearer Resource Request Failure Indication message embedded with the ID of the network recommended or specified by the PCRF for the UE to use,sending, by the gateway device, the Bearer Resource Request Failure Indication message to the UEupon detecting that the gateway device is a Packet Data Network (PDN) Gateway (GW),generating, by the PCRF, a Policy and Charging Control (PCC) rule corresponding to the specified network,and sending the PCC rule to the PDN GWsetting up by the PDN GW resources for the UE in the specified network according to the PCC rule;
forming the Bearer Resource Request Failure Indication message further comprises inserting in said indication message an indication-that the resources have been set up in the specified network,if a Bearer Binding and Event Reporting Function (BBERF) exists in the specified network, the method further comprises;
generating, by the PCRF, a corresponding PCC rule and sending the PCC rule to the BBERF so that the BBERF sets up resources between the BBERF and the UE in the specified network according to the PCC rule.

Abstract
A resource control method, a relevant device, and a relevant system are disclosed in embodiments of the present invention. The resource control method includes: determining another network suitable for a User Equipment (UE) according to resource information requested by the UE when the UE accesses multiple networks using a same Access Point Name (APN) and sends a resource request in a current network, and notifying information about the determined another network to the UE. By using the technical solutions provided in the embodiment of the present invention, a network-side device can properly control resources.

1. A resource control method, comprising:
-
receiving from User Equipment (UE) currently associated with a network a resource request message configured for accessing multiple networks using a same Access Point Name (APN) determining another network suitable for the UE according to resource information specified in said request, and notifying information about the determined another network to the UE, said notifying comprises; determining that a network-side device refuses to accept the resource request message sent by the UE in the current network, in response to said refusal, sending, by a Policy and Charging Rule Function (PCRF), an identifier (ID) of a network recommended or specified by the PCRF for the UE to use to a gateway device; and forming a Bearer Resource Request Failure Indication message embedded with the ID of the network recommended or specified by the PCRF for the UE to use, sending, by the gateway device, the Bearer Resource Request Failure Indication message to the UE upon detecting that the gateway device is a Packet Data Network (PDN) Gateway (GW), generating, by the PCRF, a Policy and Charging Control (PCC) rule corresponding to the specified network, and sending the PCC rule to the PDN GW setting up by the PDN GW resources for the UE in the specified network according to the PCC rule; forming the Bearer Resource Request Failure Indication message further comprises inserting in said indication message an indication-that the resources have been set up in the specified network, if a Bearer Binding and Event Reporting Function (BBERF) exists in the specified network, the method further comprises; generating, by the PCRF, a corresponding PCC rule and sending the PCC rule to the BBERF so that the BBERF sets up resources between the BBERF and the UE in the specified network according to the PCC rule. - View Dependent Claims (2, 3, 4, 5, 6, 7)

8. A network device, comprising:
-
a determining processor configured to; receive a resource request from a User Equipment (UE) to access multiple networks using a same Access Point Name (APN); determine another network suitable for the UE based on said resource request message a sending unit, configured to send a notification message to the UE, wherein the notification message comprises information about the determined another network, wherein; the network device is a Policy and Charging Rule Function (PCRF); and
,upon detecting that a network-side device refuses to accept the resource request sent by the UE in the current network, the sending unit is configured to; form a Bearer Resource Request Failure Indication message embedded with an identifier (ID) of a network recommended or specified by the PCRF for the UE to use, send the Bearer Resource Request Failure Indication message to a gateway device; the network device further comprising; a first processing unit, configured to; generate a Policy and Charging Control (PCC) rule corresponding to the specified network, and send the PCC rule to the gateway device so that the gateway device sets up resources for the UE in the specified network according to the PCC rule; if a Bearer Binding and Event Reporting Function (BBERF) exists in the specified network, the first processing unit is furthered configured to; generating, by the PCRF, a corresponding PCC rule and sending the PCC rule to the BBERF so that the BBERF sets up resources between the BBERF and the UE in the specified network according to the PCC rule. - View Dependent Claims (9, 10, 11, 12)

13. A network system, comprising:
-
a Policy and Charging Rule Function (PCRF), comprising; a determining processor configured to; receive a resource request from a User Equipment (UE) via a Packet Data Network (PDN) Gateway (GW) to access multiple networks using a same Access Point Name (APN); determine another network suitable for the UE based on said resource request message a sending unit, configured to send a notification message to the UE, wherein the notification message comprises information about the determined another network, the PCRF is further configured to; upon detecting that a network-side device refuses to accept the resource request sent by the UE in the current network, form a Bearer Resource Request Failure Indication message embedded with an identifier (ID) of a network recommended or specified by the PCRF for the UE to use, and send the Bearer Resource Request Failure Indication message to a gateway device, generate a Policy and Charging Control (PCC) rule corresponding to the determined network, and send the PCC rule to the PDN GW; and the PDN GW sets up resources for the UE in the specified network according to the PCC rule; if a Bearer Binding and Event Reporting Function (BBERF) exists in the specified network, the first processing unit is furthered configured to; generating, by the PCRF, a corresponding PCC rule and sending the PCC rule to the BBERF; and the BBERF is configured to sets up resources between the BBERF and the UE in the specified network according to the PCC rule.
