Abstract: This application discloses a communication method and a related device. The communication method includes: A first in-domain device determines an address length, where the “in-domain” refers to being in a local area network. Then, the first in-domain device receives a data packet, and extracts an address from the data packet based on the address length. Further, the first in-domain device forwards the data packet based on the address.

Abstract: Method and system for setting up a bearer are disclosed. The bearer setup method includes these steps: a packet data network gateway (PGW) obtains first quality of service (QoS) information and a first bearer identifier (ID), and sets up a bearer between the PGW and a radio access network (RAN) according to the first QoS information, where the bearer is associated with the first bearer ID; the RAN sets up a radio bearer (RB) with a user equipment (UE) according to second QoS information associated with the first QoS information, where the RB is associated with a second bearer ID associated with the first bearer ID.
