Multihomed communication device

摘要

The invention relates to a method for routing an uplink IP packet of a cellular device. The method comprises obtaining, by a routing client of the cellular device, a routing rule from a routing server, routing the uplink IP packet, according to the routing rule, through a first PDN connection or through a second PDN connection, both PDN connections being established over the same cellular radio interface of the cellular device. The invention also relates to a corresponding cellular device.

1. A method for routing a data packet of a user equipment (UE) in a wireless communication network, the method comprising:
establishing a packet data network (PDN) connection via a cellular access network; obtaining, by the UE from an Access Network Discovery and Selection Function (ANDSF) server, a routing rule including information on an access point name (APN) and a priority of the APN, the APN identifying a packet data network (PDN) connection; and performing, by the UE, an offload function by selecting a gateway via the cellular access network based on the priority of the APN, wherein the routing rule comprises identification information in a form of an internet protocol (IP) 5-tuple allowing the UE to identify a candidate traffic class of the data packet.
