Abstract: A heterogeneous radio access network system includes a mobile device and a first base station operated in a first wireless access network. The mobile device is wireless communicated with the first base station. One of the mobile device and the first base station sends a traffic steering initial message to request a traffic steering operation, the traffic steering initial message including a plurality of traffic flows. The other one of the mobile device and the first base station decides whether to accept or reject the traffic steering initial message. If the other one of the mobile device and the first base station accepts the traffic steering initial message, the mobile device performs a selective traffic steering, wherein the selective traffic steering comprises traffic flow(s), and the traffic flow(s) in the selective traffic steering are selected among the traffic flows of the traffic steering initial message.

Abstract: A method for buffer status report (BSR) in dual connectivity for a communication device in a wireless communication system is disclosed. The method comprises connecting to at least two base stations including a first base station and a second base station in the wireless communication system, receiving a BSR configuration from the first base station, wherein the BSR configuration indicates a calculation scheme for a BSR, and calculating buffer sizes indicated in a first BSR and a second BSR respectively for the first base station and the second base station according to the calculation scheme in the received BSR configuration, wherein at least a first logical channel of a first logical channel group reported by the first BSR and at least a second logical channel of a second logical channel group reported by the second BSR are mapped to the same split radio bearer.

Abstract: A method of service level differentiation at a radio access network, a wireless network system and a radio access network (RAN) access node are provided. The method of service level traffic differentiation at the radio access network includes the following steps: A core network transmits a data flow information including a flow ID to a RAN access node via a user plane packet of an interface between the core network and the RAN access node. The RAN access node sets up a data connection with a user equipment according to the data flow information.
