Problems solved by technology

However, BBERF cannot obtain the range of the IP CAN Session corresponding to the HoA from the relevant information of the IP CAN Session corresponding to the CoA carried on the Gxa session, and the prior art does not specify when the policy control related information is transmitted on the Gxa session. Applicable IP CAN Session-wide methods
Therefore, under the existing technology, BBERF cannot obtain the scope of application of these policy control-related information, and cannot apply these policy control-related information to control user services and network resources

Embodiment 2

[0069] The method in Embodiment 2 realizes: when the UE establishes an IP CAN Session to a certain PDN, the PCEF initiates the establishment of the IP CAN Session and its corresponding Gx session to the PCRF, and carries a tunnel in the GRE encapsulation format of the service data flow of the IP CANSession Encapsulation header, PCRF uses the GRE-Key in the tunnel encapsulation header as the indication information of the IP CAN Session range, sends the GRE-Key and the uplink AMBR of the IPCAN Session to BBERF, and BBERF applies the uplink AMBR to the corresponding IP CAN Uplink non-GBR service data flow in the session range.

[0070] Such as Figure 4 as shown, Figure 4 A schematic flowchart of the method for specifying the scope of application of policy control-related information in Embodiment 3 of the present invention is given.

[0071] In step 401, the UE is attached to the non-3gpp network, the non-3gpp network allocates a CoA for the UE, and a corresponding Gx...

Embodiment 3

[0080] The method of Embodiment 3 realizes: when the UE establishes an IP CAN Session to a certain PDN, the PCEF initiates the establishment of the IP CAN Session and its corresponding Gx session to the PCRF, and carries a tunnel in the GRE encapsulation format of the service data flow of the IP CANSession Encapsulation header, PCRF uses the combination of GRE-Key, CoA, tunnel PGW end address, and upper layer protocol type (GRE) in the tunnel encapsulation header as the indication information of the IP CAN Session range, and successively the indication information and the The uplink AMBR of the IP CANSession is delivered to the BBERF, and the BBERF applies the uplink AMBR to the uplink non-GBR service data flow within the scope of the corresponding IPCAN Session.

[0081] Such as Figure 5 as shown, Figure 5 A schematic flowchart of a method for specifying the scope of application of policy control-related information in Embodiment 4 of the present invention is given. ...

Embodiment 4

[0091] The method of Embodiment 4 realizes: when the UE establishes an IP CAN Session to a certain PDN, the PCEF initiates the establishment of the IP CAN Session and its corresponding Gx session to the PCRF, and carries a tunnel in the GRE encapsulation format of the service data flow of the IP CANSession The encapsulation header, PCRF generates the indication information of the IP CAN Session range of the IP CAN Session according to the GRE-Key in the tunnel encapsulation header, and successively reports and subscribes the indication information and the events of the IP CAN Session to BBERF, BBERF Apply the event reporting subscription to the corresponding IP CAN Session scope.

[0092] Such as Figure 6 as shown, Figure 6 A schematic structural diagram of a device for specifying the scope of application of policy control-related information in Embodiment 5 of the present invention is given.

Abstract

The embodiment of the invention discloses a method and a device for controlling a policy to ensure that BBERF applies policy control according to an appointed range. The method for applying policy control comprises the following steps that: a function of carrying bonding and event reporting receives policy control related information of IP CAN Session and indication information of a range of the IP CAN Session; and the function of carrying bonding and event reporting applies the policy control related information of the IP CAN Session according to the indication information of the range of the IP CAN Session. The device for controlling the policy comprises a receiving unit and an issuing unit, wherein the receiving unit receives tunnel encapsulation head information of a service data flow of the IP CAN Session reported by a policy and charge execution function; and the issuing unit issues the policy control related information of the IP CAN Session and the indication information of the range of the IP CAN Session to the function of carrying bonding and event reporting.

Description

technical field [0001] The present invention relates to the communication field, in particular to a policy control method and device. Background technique [0002] Such as figure 1 as shown, figure 1 Given 3GPP (Third Generation Partnership Project, the third generation cooperation project) SAE (System Architecture Evolution, system architecture evolution), UE (User Equipment, user equipment) accesses EPC (EvolvedPacket Core, EvolvedPacket Core, Evolved packet core) policy control architecture, where the role of each functional entity is described as follows: [0003] PDN (Packet Data Network, packet data network), generally an IP network, if the IP address of the PDN is assigned to a UE, the UE can access the PDN; [0004] PCRF (Policy Control and Charging Rules Function, policy control and charging rules function), this functional entity determines the corresponding policy according to the restrictions on user access to the network, operator policies, user subscription ...
