Method and apparatus for controlling traffic steering and communications system
This application provides a method and apparatus for controlling traffic steering and a communications system. In an implementation of the method for controlling traffic steering, the method is applicable to an RAN node and includes: traffic steering indication information is determined; and the traffic steering indication information is transmitted to UE, so that the UE steers corresponding traffic to a traffic steering target according to the traffic steering indication information. With the method, load balance between 3GPP RAN and WLAN at an RAN level may be ensured, and in comparison with an existing mechanism, user experiences and system performance are improved.
1. An apparatus for controlling traffic steering, applicable to a Radio Access Network (RAN) node, the apparatus comprising:
a controller configured to determine a traffic steering target; and
a transmitter configured to transmit a traffic steering command to a User Equipment (UE), the traffic steering command directing the UE to steer corresponding traffic to the traffic steering target,
wherein the traffic steering command includes at least one selected from the group of: the traffic steering target and bearer ID; and a traffic steering ratio and a shift range, and combinations thereof.
2. The apparatus according to claim 1 , wherein if the UE does not support an Access Network Discovery and Selection Function (ANDSF), the transmitter transmits the traffic steering command.
3. The apparatus according to claim 1 , further comprising;
a receiver configured to receive traffic steering indication information transmitted by UE.
4. An apparatus for controlling traffic steering, applicable to a User Equipment (UE), the apparatus comprising:
a receiver configured to receive a traffic steering command from a Radio Access Network (RAN) node; and
a controller configured to steer corresponding traffic to a traffic steering target according to the traffic steering command, wherein the traffic steering command includes at least one selected from the group of: the traffic steering target and bearer ID; and a traffic steering ratio and a shift range, and combinations thereof.
