20110173332 | METHOD AND SYSTEM FOR IMPLEMENTING POLICY AND CHARGING CONTROL IN MULTI-PDN SCENARIO - A method for implementing Policy and Charging Control (PCC) in a multi-Packet Data Network (PDN) scenario is disclosed. The method includes: a Visited Policy Control and Charging Rules Function (VPCRF) receives PCC rules and the associated S9 sub-session information from a Home Policy Control and Charging Rules Function (HPCRF), and sends the PCC rules according to the associated S9 sub-session information. The S9 session message carries associated S9 sub-session information, and therefore, in a multi-PDN scenario, the S9 session can distinguish and handle creation, modification and deletion of the Internet Protocol Connectivity Access Network (IP-CAN) session and the gateway control session, and the VPCRF can understand the information delivered by the HPCRF, and send the information to the correct Policy and Charging Enforcement Function (PCEF) or Bearer Binding and Event Reporting Function (BBERF) for enforcement; moreover, the VPCRF can report the PDN connection release information to the HPCRF, and the HPCRF releases the corresponding PDN connection, thus avoiding ineffective occupation of resources and ensuring correct policies. | 07-14-2011 |
20130100862 | CONTROL METHOD, SYSTEM AND FUNCTION ENTITY FOR REPORTING BEARER EVENT OF SIGNALING IP FLOW - A control method, system and function entity for reporting a bearer event of a signaling IP flow are provided. Flow identifier information may be generated for a signaling IP flow and a media IP flow, to unify a mechanism for reporting a signaling path status and a mechanism for reporting a bearer event of a media IP flow. In the method, the mechanism for reporting a signaling path status is not limited by the parameter of Flow Usage. | 04-25-2013 |
20140011512 | METHOD, APPARATUS, AND SYSTEM FOR CONTROLLING SERVICES - The present invention provides a method, an apparatus, and a system for controlling services, where the method includes: receiving, by a PCRF, congestion state information on a cell, resource-related information on the cell, and subscriber-related information on a UE in an activated state in the cell that are sent by an access network device; generating, by the PCRF, a QoS policy and/or a charging policy for the UE in the activated state in the cell according to the congestion state information on the cell, the resource-related information on the cell, and the subscriber-related information on the UE in the activated state in the cell; sending, by the PCRF, the generated QoS policy and/or charging policy to a PCEF, so as to enable the PCEF to execute the QoS policy and/or the charging policy. | 01-09-2014 |
20140064074 | SERVICE PROCESSING METHOD AND SYSTEM, AND POLICY CONTROL AND CHARGING RULES FUNCTION - A service processing method, a service processing system, and a PCRF entity are disclosed to overcome this defect in the prior art: The prior art is unable to handle services discriminatively according to the policy context information when different services require the same QoS level. The method includes: receiving bearer priority information from a PCRF entity, where the bearer priority information includes: bearer priority information of a service data stream, bearer priority information of an IP-CAN session, and/or bearer priority information of an IP-CAN bearer; and handling services according to the bearer priority information. In the embodiments of the present disclosure, the policy context information is converted into bearer priority information so that the PCEF handles services according to the bearer priority information. In this way, different services that require the same QoS level are handled discriminatively according to the policy context information. | 03-06-2014 |
20140094139 | SESSION PROCESSING METHOD AND APPARATUS OF MACHINE TYPE COMMUNICATION - Embodiments of the present disclosure provide a session processing method and apparatus of machine type communication. The method includes: receiving, by a first network device, a session request message; acquiring, by the first network device, subscription information according to a device parameter; and generating, by the first network device, a policy and charging control rule PCC rule of a subscriber of a UE according to the subscription information, carrying the PCC rule in a session response message, and sending the session response message. In the session processing method and apparatus according to the embodiments of the present disclosure, explicit binding of an MTC UE Category to a Low cost MTC service is implemented, so that it is ensured that the cost reduction technology does not affect the performance of a UE that belongs to an existing UE Category, thereby improving network performance of a communication system. | 04-03-2014 |
20150063310 | Method and Apparatus for Removing Policy and Charging Control Rule from Default Bearer - The present invention provides a method and an apparatus for removing a policy and charging control rule from a default bearer. The method includes: determining whether a received service flow is a service flow of SRVCC switching upon receipt of flow description information of the service flow; and, if the received service flow is the service flow of the SRVCC switching, removing a policy and charging control rule that has been activated on a default bearer for the SRVCC switching, and at the same time issuing a policy and charging control rule made for a newly created bearer. | 03-05-2015 |
20150085662 | METHOD, APPARATUS, AND SYSTEM FOR CONTROLLING SERVICES - A method, an apparatus, and a system control services, where the method includes: receiving, by a PCRF, congestion state information on a cell, resource-related information on the cell, and subscriber-related information on a UE in an activated state in the cell that are sent by an access network device; generating, by the PCRF, a QoS policy and/or a charging policy for the UE in the activated state in the cell according to the congestion state information on the cell, the resource-related information on the cell, and the subscriber-related information on the UE in the activated state in the cell; sending, by the PCRF, the generated QoS policy and/or charging policy to a PCEF, so as to enable the PCEF to execute the QoS policy and/or the charging policy. | 03-26-2015 |
20150207636 | METHOD, SYSTEM, AND ENTITY FOR EXERCISING POLICY CONTROL - A method and a system for exercising policy control, a policy and charging enforcement function (PCEF) are provided, which can solve the problem that no policy control can be exercised over application service flows without an application function (AF). In the method, a PCRF receives information about an application event sent by a PCEF after subscribing the application event from the PCEF; and the PCRF generates a control policy for a service flow of the application according to the information about the application event. In the present invention, the PCEF sends the obtained information about the application event to the PCRF, so that even when no AF is involved, the PCRF can still generate a control policy according to policy contexts including the information about the application event and the like. | 07-23-2015 |
