FIELD: information technology.
SUBSTANCE: invention relates to data transmission. Method comprises receiving, by a gateway general packet radio service support node (GGSN), 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.
EFFECT: increased accuracy of identifying a network tethering behavior to the network and wider range of applicable scenarios for identifying a network tethering behavior.
