A method for reducing call initiation collisions in a wireless communication system, the method comprising: receiving, at a user equipment, UE, a broadcast notification message from an eNodeB, the broadcast notification message comprising information regarding an action type being related to sending a call initiation request; wherein the action type comprises a first action type indicating sending the call initiation request to the eNodeB, a second action type indicating waiting a predetermined time duration for sending the call initiation request to the eNodeB, and a third action type indicating an action of changing a frequency for the sending the call initiation request; selecting, at the UE, a number randomly in range of 0 to 1; determining in which of a plurality of ranges the selected number occurs, wherein each action type corresponds to each of the plurality of ranges, and performing an operation according to the action type corresponding to each of the plurality of predetermined ranges based upon the selected number and the broadcast notification message, wherein the UE sends the call initiation request to the eNodeB according to the first action type if the selected number is smaller than a first threshold value, wherein the UE waits a predetermined time duration for sending the call initiation request to the eNodeB according to the second action type if the selected number is more than the first threshold value and smaller than a second threshold value, wherein the UE changes a frequency for the sending the call initiation request according to the third action type if the selected number is more than the second threshold value and smaller than 1, and wherein the broadcast notification message is received while the UE is in a radio resource control, RRC, IDLE mode and prior to the UE operating in a RRC CONNECTED mode. receiving, at a user equipment, UE, a broadcast notification message from an eNodeB, the broadcast notification message comprising information regarding an action type being related to sending a call initiation request; wherein the action type comprises a first action type indicating sending the call initiation request to the eNodeB, a second action type indicating waiting a predetermined time duration for sending the call initiation request to the eNodeB, and a third action type indicating an action of changing a frequency for the sending the call initiation request; selecting, at the UE, a number randomly in range of 0 to 1; determining in which of a plurality of ranges the selected number occurs, wherein each action type corresponds to each of the plurality of ranges, and performing an operation according to the action type corresponding to each of the plurality of predetermined ranges based upon the selected number and the broadcast notification message, wherein the UE sends the call initiation request to the eNodeB according to the first action type if the selected number is smaller than a first threshold value, wherein the UE waits a predetermined time duration for sending the call initiation request to the eNodeB according to the second action type if the selected number is more than the first threshold value and smaller than a second threshold value, wherein the UE changes a frequency for the sending the call initiation request according to the third action type if the selected number is more than the second threshold value and smaller than 1, and wherein the broadcast notification message is received while the UE is in a radio resource control, RRC, IDLE mode and prior to the UE operating in a RRC CONNECTED mode.
