Abstract: A method and system performs antenna tuning which enhances radio frequency (RF) tuner reliability within a wireless communication device (WCD). The WCD, in response to receiving a request to change an active RF tuning state, retrieves component usage data corresponding to components of a tuning circuit that is tunable to an RF operating channel. The WCD selectively determines, using device environment state data and/or RF state data and the component usage data, an RF tuning state tuned to the RF operating channel. The selected RF tuning state (a) satisfies tuning performance specifications and (b) enhances component reliability performance by minimizing an operational wear on tuning circuit components. The WCD configures the tuning circuit using the selected RF tuning state and tracks session parameter values for tuning circuit components during a corresponding communication session.

Abstract: An apparatus includes an emergency services location module, operatively coupled to location hardware. The emergency services location module is operative to receive a session certificate from an emergency services network entity in response to the apparatus placing an emergency services call or sending an emergency services message. The emergency services location module validates the session certificate to validate that the emergency services network entity is authorized to receive location information, and sends location information obtained from the location hardware to the emergency services network entity, in response to validating the session certificate. The emergency services location module may also be operative to override a user privacy setting that prevents location information from being sent from the apparatus, in response to determining that the session certificate is valid.

Abstract: Methods and apparatus for serving content to a wireless device (106) are disclosed. In an embodiment, a gateway (114), or any other suitable device or system, determines that at least one message (e.g., a text or text-like message) containing a first pointer (e.g., a unicast URL) to the content (e.g., a web page) is to be transmitted via an emergency alert system (e.g., CMAS). In response thereto, the gateway (114) obtains the content using the first pointer and generates a second different pointer (e.g., a multicast/broadcast URL) to the content. The gateway (114) provides at least a portion of the at least one message and the second pointer for transmission via the emergency alert system (118). The gateway (114) also provides the content for transmission via a wireless multicast/broadcast channel (120) based on the second pointer.

Abstract: The invention relates to a system that enables power to be selectively applied to GPS circuitry in a cellular telephone or other mobile device only when a specific user input is detected. In one embodiment, power to the GPS circuitry may be enabled only when the user strikes the keys “9-1-1.” In other embodiments, other types of GPS enablement or disablement may be employed, such as selectively decoupling the GPS antenna. In another embodiment, the user may depress a privacy bypass button, which alternately enables and disables power to the GPS circuitry. Cellular telephones or other communication devices may therefore activate GPS location service during an emergency call, or when a user wishes to allow their location to be determined, but protect the privacy of that user's location and movement at other times.

Abstract: Disclosed is a method (200) for charging energy storage devices. The method (200) can include a battery charging method in a power supply client connected by a data bus to a power supply host. The method (200) includes the steps of: detecting (210) a state of the power supply host; determining (220) a limit of current from the host to the client; allocating (230) a portion of the limit to a battery charging current; and charging (240) a battery of the client at the battery charging current such that the current from the host is greater than a recommended limit and less than or equal to the determined amount. Thus a client device can confidently charge at a rate which causes the port current to exceed a recommended limit, such as a USB port limit of 500 mA, when allowed by conditions of the host device.

Abstract: A method for locating a wireless communications device WCD (102). The method includes the step of receiving at the WCD (102) a wireless transmission comprising a first auto-location trigger signal. The WCD (102), responsive to the first auto-location trigger signal, operates in an auto-location mode. The auto-location mode includes the automatic collection and communication of predetermined first data, such as audio, video, and GPS location data. After the automatic collection and communication step of the first data is complete, the WCD (102) enters into a standby mode. The standby mode continues until a state detection device (206) of the WCD (102) detects a change in the state of the WCD (102). These changes in state are exclusive of the wireless transmission comprising the first auto-location trigger signal. The change(s) in state produce a second auto-location trigger signal, which causes the automatic collection and communication of a second data that is the same or similar to the first data.
