Abstract: Operating conditions of a remote device and operating conditions of a local device are compared, where the local device and the remote device are located within a predetermined proximity of a wireless network. An advertisement request is transmitted from the local device to the remote device based on the comparison of the operating conditions of the local device and the remote device. The advertisement request includes information identifying one or more services advertised by the local device, whereby the remote device is configured to advertise the one or more services on behalf of the local device in the wireless network.

Abstract: Embodiments of the invention perform a preliminary scan for information automatically transmitted by available wireless access points. The information transmitted by access points (e.g., identity information) and information derived from the transmission (e.g., signal strength) is used to prioritize the available wireless access points before direct scanning takes place.

Abstract: Methods and apparatuses for operating a wireless mobile station configured to communicate with a wireless access point are described. A wireless mobile station can determine an interval of time between successive target beacon transmission times. The wireless mobile station can adjust, based at least in part on the interval of time, a period of time of an awake timer in response to having determined the interval of time.

Abstract: A local device is configured to monitor operating conditions coupled to a wireless network. An advertisement period is dynamically adjusted based on the operating conditions of the local device, where the advertisement period is dynamically adjusted based on at least one of a battery condition of the local device, a user behavior of the local device, network traffic condition, and a type of service to be advertised. The local device broadcasts a service advertisement in the wireless network according to the adjusted advertisement period, the service advertisement including one or more service IDs for identifying one or more services to be advertised from the local device.

Abstract: Methods and apparatuses for operating a wireless mobile station configured to communicate with a wireless access point are described. A first awake timer may be started in response to receiving a beacon signal from the wireless access point. The beacon signal may indicate that data is available or pending for the wireless mobile station. A second awake timer may be started in response to data received from the wireless access point. When the second awake timer expires, the wireless mobile station may return to the sleep state. In one embodiment, the first awake timer counts for a first period of time and the second awake timer counts for a second period of time which is shorter than the first period of time. The RF radio may be in a higher power state when the first and/or the second awake timers are counting. In one embodiment, the wireless mobile station and the wireless access points may be synchronized using target beacon transmission times of the beacon signal.

Abstract: A local device broadcasts a first advertisement in a first wireless network via a first wireless interface, where the first advertisement includes one or more service identifiers (IDs) identifying one or more services being advertised and an availability schedule of the local device in the first wireless network. The local device broadcasts a second advertisement in a second wireless network via a second wireless interface. The local device scans in the first wireless network during an availability window of the availability schedule for a response to the first advertisement, where the broadcast of the second advertisement is disabled during the availability window.

Abstract: A local device broadcasts a service advertisement in a wireless network, where the service advertisement includes one or more service identifiers (IDs) identifying one or more services being advertised and an availability schedule of the local device. Optionally, the local device reduces power to at least a portion of the local device and wakes up at a time according to the availability schedule. The local device listens in the wireless network according to the availability schedule of the local device. In response to a service request received from a remote device during the availability window, the local device transmits a service response to the remote device. The service request includes one or more service IDs identifying one or more services being inquired by the remote device and the service response includes detailed information associated with one or more services identified by the one or more service IDs.

Abstract: Methods and apparatuses for operating a wireless mobile station configured to communicate with a wireless access point are described. A sleep state may be maintained in which a radio frequency (RF) radio in the wireless mobile station is in a low power state. The wireless station may use a plurality of sleep states, each with a different sleep timer period based upon recent network activity. In one embodiment, a device may have two sleep states with two sleep timers, and in another embodiment a device may have three sleep timers for three sleep states. The first sleep time may be started for a first sleep state and to determine when to awake the device to determine whether there is any network activity. The device then determines whether a first period of network inactivity has occurred and, if so, it starts a second sleep timer for a second sleep state in response to determining that the first period of network inactivity has occurred.
