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.

A method of service level traffic differentiation at a radio access network of a wireless network system, comprising:
- transmitting a data flow information comprising a flow ID to a radio access network access node (RAN access node) by a core network of the wireless network system via a user plane packet of an interface between the core network and the RAN access node;
- and
- setting up a data connection with a user equipment by the RAN access node according to the data flow information;
- wherein the data flow information further comprises a service type ID;
- and
- there is a correspondence relationship between the flow ID and the service type ID, and a modification indicator prior to the flow ID indicating whether the correspondence relationship needs to be modified.
A wireless network system, comprising:
- a core network for transmitting a data flow information comprising a flow ID via a user plane packet of an interface between the core network and a RAN access node;
- the RAN access node for receiving the data flow information transmitted from the core network;
- and
- a user equipment to which a data connection is set up by the RAN access node according to the data flow information;
- wherein the data flow information further comprises a service type ID;
- the flow ID is recorded in a user plane packet header of a user plane packet, and the service type ID is recorded in a packet data unit of the user plane packet;
- and
- the service type ID is recorded in a last end of the packet data unit of the user plane packet, and a last bit of the service type ID is a last bit of the packet data unit.
A radio access network access node (RAN access node), comprising:
- a receiving unit for receiving a data flow information comprising a flow ID from a core network of a wireless network system via a user plane packet of an interface between the core network and the RAN access node;
- a processing unit for determining a bearer corresponding with the user plane packet according to the data flow information and the user equipment associated the data flow information;
- and
- a transmission unit for setting up a data connection with the user equipment according to the bearer;
- wherein the data flow information further comprises a service type ID;
- the flow ID is recorded in a user plane packet header of the user plane packet, and the service type ID is recorded in a packet data unit of the user plane packet;
- and
- the service type ID is recorded in a last end of the packet data unit of the user plane packet, and a last bit of the service type ID is a last bit of the packet data unit.
