METHODS AND DEVICES FOR SETTING UPLINK AND DOWNLINK POLICY TO PROVIDE APPLICATION SERVICES OVER MPTCP CONNECTION

摘要

A radio access network connection manager determines, based on received network condition information, a transmission policy for transmitting bearer traffic over at least one of a group consisting of a first a multipath transport control protocol (MPTCP) subflow and a second MPTCP subflow of a MPTCP connection between a radio access network element and a user equipment. The first MPTCP subflow is associated with a WLAN link, and the second MPTCP subflow is associated with a cellular link. The transmission policy is indicative of a WLAN only mode, a cellular only mode and a hybrid WLAN-cellular mode for the user equipment. A user equipment connection manager distributes uplink bearer traffic between the first multipath transport control protocol (MPTCP) subflow and the second MPTCP subflow of a MPTCP connection.
