Method of performing traffic steering in a wireless network system and related wireless network system
First Claim
1. A method of performing traffic steering in a wireless network system having a base station of a first network and a user equipment camping on the first network, comprising:
- the base station setting an indicator to a first value when determining that the first network is not loaded balancedly or setting the indicator to a second value when determining that the first network is loaded balancedly;
the base station sending the indicator, an update amount, a timer length, and at least a first radio access network (RAN) rule including a first threshold to the user equipment, wherein the update amount has a constant value larger than zero and a value of the timer length is larger than zero;
the user equipment starting a timer when receiving the first RAN rule with the indicator set to the first value from the base station;
the user equipment adjusting the first threshold by the update amount when the timer expires according to the timer length; and
the user equipment steering traffic from the first network to a second network or from the second network to the first network when the first RAN rule is satisfied according to the adjusted first threshold.

Abstract
A wireless network system includes a base station of a first network and a user equipment camping on the first network. The base station is configured to set an indicator to a specific value when determining that the first network is not loaded balancedly. The base station then sends the indicator, an update amount, a timer length, and at least one RAN rule including a threshold to the user equipment. The user equipment is configured to start a timer when receiving the at least one RAN rule with the indicator set to the specific value from the base station, adjust the threshold by the update amount when the timer expires according to the timer length, and steer traffic from the first network to a second network or from the second network to the first network when the at least one RAN rule is satisfied according to the adjusted threshold.

8. A wireless network system which performs traffic steering, comprising:
-
a first network including a base station configured to; set an indicator to a first value when determining that the first network is not loaded balancedly or set the indicator to a second value when determining that the first network is loaded balancedly; and transmit the indicator, an update amount, a timer length, and at least one RAN rule including a threshold, wherein the update amount has a constant value larger than zero and a value of the timer length is larger than zero; a second network; and a user equipment currently camping on the first network and configured to; start a timer when receiving the at least one RAN rule with the indicator set to the first value from the base station; adjust the threshold by the update amount when the timer expires according to the timer length; and steer traffic from the first network to the second network or from the second network to the first network when the first RAN rule is satisfied according to the adjusted threshold. - View Dependent Claims (9)
