    • A method and device are disclosed from the perspective of a first User Equipment (UE) to establish one-to-one connection between the first UE and a second UE. In one embodiment, the method includes the first UE initiating a first procedure of establishing the one-to-one connection with the second UE for a unicast communication between the first UE and the second UE or for a UE-to-UE communication between the first UE and a third UE via the second UE or a second procedure of establishing the one-to-one connection with the second UE for a UE-to-Network communication between the first UE and a network node via the second UE. The method also includes the first UE transmitting a first PC5-S message to the second UE for completing establishment of a first security context in the first procedure of establishing the one-to-one connection with the second UE for the unicast communication or the UE-to-UE communication if the first procedure is initiated, wherein the first PC5-S message includes Quality of Service (QoS) information for the unicast communication or the UE-to-UE communication. The method further includes the first UE transmitting a second PC5-S message to the second UE for completing establishment of a second security context in the second procedure of establishing the one-to-one connection with the second UE for the UE-to-Network communication if the second procedure is initiated, wherein the second PC5-S message does not include any QoS information for the UE-to-Network communication.
