A power management method, in which creation of deliver opportunities for a wireless station (STA) of a WLAN system is managed using a designated sub-field of the frame control field in a MAC header. In one embodiment, the STA is adapted (i) to use the power management sub-field to communicate its power state to the access point (AP) and (ii) to run a periodicity timer, which starts when the STA has transitioned to the doze state.

A power management method, in which duration of deliver opportunities for a wireless station (STA) of a WLAN system is managed using a designated sub-field of the frame control field in a MAC header. Either the STA or the access point (AP) can terminate the deliver opportunity, e.g., based on the amount traffic. In one embodiment, the STA is adapted (i) to use the power management sub-field to communicate its power state to the AP and (ii) to run a maximum-wait timer, which starts when the AP is informed that the STA is in the awake state. The STA transitions to the doze state either when it has received a data frame from the AP or when the maximum-wait timer runs out. In another embodiment, the AP and STA manage deliver opportunities by entering a new mode of operation referred to as interactive traffic power management (ITPM) mode. During this mode the power management sub-field is ignored and the more data sub-field is used to communicate the availability of data and to manage transitions of the STA between the awake and doze states. Embodiments of the invention improve WLAN system performance when the traffic load is such that data frames become available for transmission both at the STA and AP at relatively regular intervals, which is typically the case for interactive voice-over-WLAN applications.

Some embodiments relate to a cellular network which better utilizes packet-switched (PS) voice technologies, such as VoLTE, for roaming user equipment (UE) devices. When a roaming UE associated with a home cellular carrier that does not support PS to CS handover (SRVCC) desires to make a VoLTE call, the cellular network may determine probability of such a handover during the the call. The cellular network may selectively accept or reject the packet-switched wireless voice call based on the handover probability. If the probability of handover is high, the cellular network may reject the packet-switched wireless voice and trigger the UE to fall back to a circuit-switched network and re-originate the wireless voice call on the circuit-switched network. In the case of a mobile terminated call, the cellular network may provide signaling to the UE to perform a fallback to a circuit-switched network in order to receive the mobile terminated call.
