This disclosure relates to reducing battery usage in handheld communication devices due to operation of variable managed features, such as a location determination feature and other features that consume variable amounts of time and power. The techniques of this disclosure include dynamically managing a power budget allocated to one or more variable managed features of the handheld communication device based on power consumption over time by the variable managed features. More specifically, the techniques include, for each variable managed feature, recalculating a frequency for performing power events based on an amount of remaining power after one or more power events. The techniques also include reallocating the power budget to the one or more variable managed features based on an amount of remaining power after one or more power events of the variable managed features, a pre-determined period of time, or reaching a threshold level of power consumption jitter.

Dynamic feature-aware power management

A method of providing content notifications to devices in a wireless communication system includes obtaining notification information regarding content available to a first group of mobile devices in a wireless network, generating a notification message comprising the notification information and an identifier associated with a second group of mobile devices that is a subset of the first group, and broadcasting the notification message over the network to cause mobile devices of the second group to retrieve the content over the network. The method also includes receiving content notifications in a wireless communication system, including receiving a notification message comprising notification information regarding content available to a first group of mobile devices and an identifier associated with a second group of devices, where the second group is a subset of the first group, and retrieving content from a network in response to being one of the second group of devices.

A novel power conservation scheme is provided for conserving power in a wireless client terminal with an established communication session. While in a connected mode, the client terminal may receive data for the communication session via a data channel from an access point. During periods of inactivity over the data channel, the client terminal may switch to a lowered power mode, where the client terminal discontinuously monitors a control channel and does not monitor the data channel. The access point is informed of the operating mode of the client terminal. If a data resume indicator is received over the control channel, the client terminal switches back to the connected mode and resumes the communication session by receiving additional data over the data channel.

A novel power conservation scheme is provided for conserving power in client terminals by using a proxy server. The client terminal may have a secondary communication interface for short range communications and a primary communication interface for long range communications with an access point for a wireless network. To conserve power, the client terminal may power down its primary communication interface without informing the access point. The access point assumes the primary communication interface is still active. Prior to shutting off its primary communication interface, the client terminal may assign an external proxy device to act as a proxy and monitor its data channel with the access point. The proxy device monitors the data channel(s) for the client terminal via a primary communication interface. If the proxy device detects a data message for the client terminal, it forwards the data message to the client terminal via a secondary communication interface.

Power conservation in wireless client terminals using proxy device

Various arrangements for managing wireless network communication are described. Two cells using different radio access technologies (RATs), such as a 3G cell and a 4G cell, may provide overlapping coverage. A first cell using a first RAT, under certain circumstances, may be permitted to enter a powered down state such that less power is consumed. User equipment may communicate with the cell using the second RAT as the preferred network and only communicate with the cell using the first RAT when a service available through the first RAT but not the second RAT has been requested. Upon a request from the second cell, the first cell may enter a powered up state.

Cellular network energy saving

Methods, apparatus, systems and computer program products are defined for enhancing the delivery of overhead notifications in a broadcast network, in particular a broadcast network suitable for wireless device implementation. The broadcast-receiving devices only receive new notification messages, as opposed to receiving all of the currently active notification messages. This is achieved by broadcasting a listing of the currently active notifications versions and having the devices compare the currently active notification versions to the locally stored version(s) to determine which version or versions require capturing. In those aspects in which the broadcast-receiving device is a battery powered wireless device, battery power consumption is minimized because the device only captures active notification messages not currently in device memory, as opposed to all of the currently active notifications.

Enhanced notification mechanism for broadcast networks using bit-map vectors

Systems and methodologies are described that facilitate providing software upgrade notifications to user devices that utilize unicast and multicast communication techniques in a wireless communication environment. Bandwidth and power consumption is minimized by permitting determination to be made regarding whether a given software update is relevant to the user device prior to attempting a download or receiving a notification thereof. Additionally, evaluation of version number and software identity facilitates determining whether to employ a unicast software check-up protocol or a multicast software check-up protocol. Software upgrade information may also be transmitted over a multicast channel for a predetermined time period, after which a user device may initiate a unicast check-up protocol to receive software upgrade information.
