Abstract: A recipient electronic device that provides an acknowledgment is described. This recipient electronic device may include a main radio and a wake-up radio (WUR) that at least selectively transitions the main radio from a lower-power mode to a higher-power mode in response to a wake-up frame. During operation, the WUR receives a wake-up frame associated with an electronic device, e.g., a second or a sending device. Then, the WUR provides, in response to the wake-up frame, the acknowledgement intended for the electronic device. The wake-up frame may specify that an acknowledgement from the recipient electronic device to the electronic device is expected. For example, the wake-up frame may specify that the acknowledgement is communicated by the recipient electronic device using the WUR in the recipient electronic device. Moreover, the WUR may provide the acknowledgment while the main radio is in the lower-power mode.

Abstract: Systems and methods for updating subscriber data are disclosed. In some embodiments, a method of operation of a serving node in a communication network for updating subscriber data includes receiving a modification of subscriber data for one or more subscribers and determining if updates to the subscriber data for the one or more subscribers are needed now. In response to determining that updates are needed now, the method includes communicating the modification for subscribers to one or more additional nodes and/or initiating other types of signaling towards other network nodes as a result. In response to determining that updates are not needed now, the method includes postponing the communication of the modification of the subscriber data for the one or more subscribers. In this way, signaling floods towards external network elements may be avoided when a modification is performed to subscription data that affects multiple subscribers (potentially even millions).
