Embodiment Construction
[0032] method embodiment
[0033] In this embodiment, a policy control method is provided, which is applied to an evolution group including a policy control and charging rule function entity (PCRF), a data network gateway, a gateway control function entity, and a home user server / authentication, authorization, and accounting server system.
[0034] Such as image 3 As shown, the policy control method according to the embodiment of the present invention includes: step S302, the policy control and charging rule functional entity sets the service quality policy, and notifies the service quality policy to the gateway control functional entity, wherein the service quality policy includes data Flow filtering rules and policy control rules corresponding to the data flow filtering rules, the data flow filtering rules at least include the home address and care-of address of the user equipment; and step S304, the gateway control functional entity detects the service data flow according...

Abstract
The invention discloses a policy control method. The method comprises the following steps: step S302: a policy control and charging rule function entity sets a service quality policy and informs the service quality policy to a gateway control function entity, wherein, the service quality policy comprises a data flow filtering rule and a policy control rule corresponding to the data flow filteringrule, and the data flow filtering rule at least includes a home address and a care-of address of subscriber equipment; and step S304:, the gateway control function entity detects the service data flow according to the data flow filtering rule, and performs the corresponding policy control rule on the data flow which conforms to the data flow filtering rule to perform the policy control. By the method and the device, the policy control taking service as granularity can be effectively realized, thus facilitating service-based operations such as service charging operation and the like.
Description
technical field [0001] The present invention relates to the communication field, and in particular, relates to a policy control method and device. Background technique [0002] Such as figure 1 As shown, the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) evolved packet system (Evolved Packet System, EPS) includes: evolved UTRAN (Evolved Universal Terrestrial Radio Access Network, E-UTRAN), mobility management unit (Mobility Management Entity, MME), Serving Gateway (Serving Gateway, S-GW), Data Network Gateway (PacketData Network Gateway, PDN GW, that is, P-GW), Home Subscriber Server (Home Subscriber Server, HSS), 3GPP authentication authorization accounting A server (3GPP AAA server), a policy and charging rules function (Policy and Charging Rules Function, PCRF), and other supporting nodes. [0003] Among them, MME is responsible for mobility management, non-access stratum signaling processing, user mobility management context management an...
