Abstract

Provided are a policy control method, device and system, which can implement policy control when a service flow of an application server in a DN accessed by a terminal device needs to be processed bya local application server in an LAN in which an intermediate user plane network element is deployed. The method comprises the following steps that: a session management network element receives localarea network LAN data guide information corresponding to a first application from a policy control network element, selects one or more user plane network elements according to the LAN data guide information, and determines a policy rule corresponding to each user plane network element in the one or more user plane network elements respectively; and respectively sending the corresponding strategyrule to each user plane network element. The strategy rule is used for guiding the data of the first application sent by the upstream network element to a local application server of the first application in the target LAN, and sending the data processed by the local application server of the first application in the target LAN to the downstream network element.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a policy control method, device and system. Background technique [0002] In the fifth generation (5th generation, 5G) network, the terminal device establishes a protocol data unit (protocol data unit, PDU) session after accessing the network, and accesses the external data network (data network, DN) through the PDU session, and deploys Application server interaction in DN. Among them, depending on the DN accessed by the user, the network can select the user plane function (user plane function, UPF) network element that accesses the DN as the PDU session anchor (PDU session anchor, PSA) according to the network policy, and access it through the N6 interface of the PSA Application server in DN. The 5G network supports the scenario where there are multiple PSAs in one PDU session, and the application server of the same application can be deployed in multiple ...
