efficient policy enforcement using network tokens for services - user plan approach

摘要

In one aspect, the invention relates to initiating, by a device, a connection to an application server associated with one or more application services. A gateway derives an uplink network token and / or a downlink network token. Tokens are delivered to the device and / or an application server through the user's plan. Tokens are included with uplink and / or downlink packages, respectively. Another aspect refers to receiving a data packet at a gateway. The gateway determines a requirement for a packet network token. The gateway derives the network token based on a device subscription profile maintained by a network. The network token can be sent with the packet to a destination address associated with the packet. A packet including a network token may be received at a gateway. The gateway can verify the network token and send the data packet to an application server or device if the verification succeeds.
