Abstract: A method for efficiently performing ranging in a wireless communication network may be implemented by a mobile station. The method may include sending a ranging code to a base station. The method may also include receiving a ranging response message from the base station. The method may also include determining whether a ranging failure condition is satisfied. The ranging failure condition may relate to something other than a duration of time. The method may further include re-sending the ranging code to the base station if the ranging failure condition is satisfied.

Abstract: The present invention provides a mobile station apparatus. The mobile station apparatus comprises an RF transmitting/receiving module, a display module, a memory comprising an RSSI database, and a control program. When the mobile station apparatus moves along a path comprising plural candidates of communication locations, the control program records a plurality of RSSIs, which are received by the RF transmitting/receiving module from the candidates along the communication locations, and at least one path parameter in the RSSI database, and then according to a predetermined display algorithm, the control program controls the display module to display at least one recorded RSSI and the corresponding path parameter as a reference, based on which the mobile station apparatus selects a communication location candidate for providing the mobile communication service.

Abstract: The invention relates to a mobile station apparatus in a communication system. The communication system comprises a plurality of base stations for providing mobile communication service within a covered communication area. The mobile station apparatus comprises a memory for recording a predetermined access control class and determining which base station the mobile station apparatus is allowed to camp on for conducting mobile communication service, a battery for providing electrical power, a control program, and a power detector for detecting the current power of the battery, so that when the power detector detects that the power is lower than a predetermined low power watermark, the power detector issues a trigger signal. When the control program receives the trigger signal, the control program overwrites the predetermined access control class, so as to allow the mobile station apparatus to conduct mobile communication service through other base stations in the communication area.

Abstract: Call processing system and method for mobile users. The processing system identifies call urgency by categorizing incoming emergency data calls, and prioritizes the data calls accordingly. The emergency call processing method comprises submitting a data call to an emergency call center, placing the data call in a queuing system according to the priority level of the emergency, and waiting for an available processing unit to call back and address the emergency. During the waiting period, the emergency call center solicits information associated with the emergency, and user equipment returns the requested information automatically. The present invention improves efficiency of the emergency call center, ensuring that the most urgent emergency is served first. Additionally, the present invention conserves battery power of user equipment by collecting relevant information beforehand using data messages.

Abstract: A radiation detection method and apparatus thereof for estimating radiation power received by the mobile station. The locations of nearby base stations and the mobile station are obtained from the broadcast system messages and the location service provided by the service provider, and based on the location information, the radiation power is estimated according to the distances between the base stations and the mobile station. In addition, the radiation estimation process also utilizes the radiation power of monitored base stations constantly measured by the mobile station for cell selection to determine the effects of interference. Based on a preset safety value and the estimated radiation power, the radiation detection device of the present invention automatically issues an alert when entering a high radiation environment.

Abstract: A method for proceeding with communications by a mobile device is provided. The method first determines if any registered public land mobile network has been stored in the mobile device. If yes, the method determines if the signals from the registered public land mobile network are clear enough to maintain a good communication quality. If yes, the method determines if the mobile device is one legitimate user of the registered public land mobile network. If yes, the mobile device starts to transmit signals via the registered public land mobile network.

Abstract: A mobile optical scanning device is proposed, which includes a power supply module, a contact image sensor (CIS) module, an application specific integrated circuit (ASIC) and a memory module. The power supply module acts as a power source for the scanning device. The scanning process can be activated by inputting a signal to the ASIC for activating a driving unit of the CIS module for scanning. Analog data obtained from scanning are then converted to digital data by a signal processing unit of the CIS module, then allowing the digital data to be stored in the memory module. With the use of an input/output processing module of the ASIC being connected with an external host, the stored data in the memory module can be read. Since the scanning device is provided with the power source and memory, it can be used for scanning and storing data even in the condition of no hose being connected therewith.

Abstract: A mobile device for power supply and data storage is proposed, which includes a power supply module, an input/output interface module, a controlling module and a memory module. When the foregoing mobile device is externally connected with a small mobile electric device, power outputted from an output circuit of the power supply module to the electric device can be adjusted by the controlling module, so as to provide a suitable amount of power for the electric device. Moreover, when data storage of the electric device is insufficient for storing further data, the controlling module allows a write in/read out unit of the input/output interface module to write in the data, and then transmits the data to the memory module to be stored therein.
