Quality of service may be enhanced for high priority traffic. A UE may communicate within a packet switched system, e.g., an LTE network. The UE may use a first or default bearer for signaling messages of high priority services and a second bearer for messages of low priority services. For example, the first bearer may have a quality of service class identifier (QCI) value of 5 while the second bearer may have a QCI value other than 5, (e.g., 6-9). The first bearer may be used for signaling messages associated with voice over IP, video over IP, and/or SMS over IP, as desired. The second bearer may be used for messages (e.g., signaling messages) associated with other, lower priority services. For example, the second bearer may be used for presence messages or instant messages or other lower priority messages.
