Claim Text:
1. A method for providing inter-Radio Access Technology (RAT) load-balancing and congestion control when a wireless device attempts to reselect a primary RAT while receiving wireless communication over a secondary RAT that is different from the primary RAT, the method comprising performing the following steps using a network entity in a Radio Access Network (RAN) supporting the secondary RAT: broadcasting a message to all idle wireless devices receiving wireless communication over the secondary RAT, wherein the message contains a control function that enables each idle wireless device to activate an inter-RAT load-balancing functionality that controls reselection of the primary RAT; providing a common probability threshold value in the broadcast message for all idle wireless devices receiving wireless communication over the secondary RAT, regardless of whether the idle wireless devices are divided into different groups; through the control function, remotely configuring each idle wireless device camped on the secondary RAT to activate the inter-RAT load-balancing functionality; and allowing only those idle wireless devices to reselect the primary RAT that generate, in response to the activation of the inter-RAT load-balancing functionality, an individual device-specific random value that is equal to or greater than the common probability threshold value.
