Method of performing traffic steering in a wireless network system and related wireless network system

摘要

A wireless network system includes abase station of a first network and a user equipment camping on the first network. The user equipment receives an indicator, a probability value within a predetermined range, and at least one RAN rule from the base station. When the indicator is set to a specific value, the user equipment generates a random value within the predetermined range. When the at least one RAN rule is satisfied and a probability condition associated with the random value and the probability value is fulfilled, the user equipment steers traffic from the first network to a second network or from the second network to the first network.

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 user equipment receiving a probability value within a predetermined range, and at least one radio access network (RAN) rule from the base station; the user equipment receiving an update amount and a timer length from the base station; the user equipment generating a first random value within the predetermined range and starting a timer; the user equipment determining if the at least one RAN rule is satisfied and if a first probability condition associated with the first random value and the probability value is fulfilled; the user equipment steering 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 and the first probability condition is fulfilled; the user equipment adjusting the probability value by the update amount from a first value to a second value after the timer expires according to the timer length when the at least one RAN rule is satisfied but the first probability condition is not fulfilled; the user equipment generating a second random value within the predetermined range; and the user equipment steering 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 and a second probability condition associated with the second random value and the adjusted probability value is fulfilled.
