In general, techniques are described for leveraging at least one of a policy control and charging or application detection architecture for an access network to dynamically control value-added services applied to packet flows. In some examples, a policy enforcement device receives a policy rule that defines at least one of policy control and application detection by an access network for a subscriber device. The policy rule includes a service chain identifier that identifies a service chain that defines one or more value-added services to be applied in a particular order to provide a composite service for application to packet flows associated to the service chain. The policy enforcement device receives a packet sourced by the subscriber device and destined to the packet data network, applies the policy rule to the packet to associate the packet to the service chain, and forwards the packet according to the service chain.
