Abstract: A method and apparatus for using a mobile phone to customize user interface is disclosed. The method comprises first providing a default user interface screen on the mobile phone in a local memory. Upon power-up by a first user, the mobile phone displays the first user interface screen for a first user of the mobile phone. Then, the mobile phone can make a data call to a first web server through a global computer information network, e.g. the Internet. The phone can brows a first desired web page at the first web server. If selected, the phone duplicates the first desired web page to the local memory as the default user interface for the first user, such that when the mobile phone is powered up by the first user, the mobile phone displays the desired web page.

Abstract: Satellite positioning system enabled mobile receivers (310) and cellular communication network base stations (330) synchronized with satellite positioning system clocks and method therefore. In a network-assisted embodiment, a variable propagation delay for transmission of an assistance message (232) from the base station to the mobile receiver is determined for correcting the handset clock (318). In others embodiments, local clock drift of mobile receivers (310) and/or base stations (330) are determined by a ratio of local and satellite time differences, based on sequential time snapshots, for use in correcting the local clocks.

Abstract: A transmission power control method subdivides one or more transmission power steps as defined in a system specification into multiple sub-steps. A base station (290) instructs a mobile station (280) to use a defined power step, and the mobile station (280) initially selects a maximum power sub-step within the requested power step during an initial RACH (225) transmission. During the duration of the call, the mobile station (280) dynamically adjusts the power sub-step based on measured signal reception quality and channel conditions. The result is an improvement in call completion rates with only a minor reduction in battery life.
