Claim One:
1. A method for identifying a network tethering behavior, the method comprising: receiving, by a gateway general packet radio service support node (GGSN), an Internet protocol (IP) packet sent by a to-be-networked device and forwarded by a mobile terminal; acquiring a time to live (TTL) value in the IP packet; determining whether the acquired TTL value is different from a specified TTL value; and if yes, determining that the to-be-networked device performs a network tethering behavior; and if the GGSN already receives a notification message delivered by a policy and charging rules function (PCRF), and the notification message carries an event trigger parameter for instructing the GGSN to report the network tethering behavior, reporting the network tethering behavior to the PCRF for notifying the mobile terminal that the to-be-networked device is using a network tethering service.
