Patent CA-2308651-A1 (CA)
Title: A method of controlling base station transmitting power during soft handoff
Inventor: HASHEM BASSAM
IPC: H04B7/005
Filed: 2000-05-17
Abstract: A mobile station in a CDMA cellular radio system transmits a possibly unique power control command every power control group time when the mobile station is in contact with a single base station. When the mobile station is in soft handoff (in communication with two or more base stations simultaneously), however, the mobile station sends the same power control command for several power control group times, thus reducing the probability of receiving an erroneous power control command at a base station. The base stations synchronize their power levels periodically according to a predetermined number of power control command groups, resulting in more optimum base station power transmission levels, in turn resulting in a reduction in system noise and an increase in system capacity.

Patent CA-2313554-A1 (CA)
Title: Method for initiating call blocking
Inventor: THOMAS MATHEW
IPC: H04M3/00
Filed: 2000-07-06
Abstract: A method that initiates call blocking responsive to a call-quality measurement of the forward link. The call-quality measurement is a measurement of how well a mobile terminal is able to receive the forward link. One call-quality measurement is a pilot fraction of the forward link, which is a ratio of the pilot's power level to the power level of a set of forward-link signals of a base station. Call blocking is initiated when an average pilot fraction is below a pilot-fraction blocking threshold. The pilot's power level is obtained for a time period, and the signal set's power level is obtained for the same time period. The pilot fraction is determined for the time period, and then used to determine the average pilot fraction for the time period. The average pilot fraction for the current time period is based on a pilot fraction for the current time period, and an average pilot fraction for a previous time period. When the average pilot fraction is below the pilot-fraction blocking threshold, call blocking is initiated.  The pilot-fraction blocking threshold is preferably based on: 1) the pilot fraction when the base station is at full load; 2) the size, shape, and terrain of the cell; and 3) the aggressiveness of the overload control. In the preferred embodiment, the signal set includes all of the signals generated by the base station, alternatively, the signal set can include fewer than all the signals generated by the base station. If the cell includes several sectors, the call blocking is initiated on a sector basis when the average pilot fraction of the sector is below the pilot-fraction blocking threshold. Other call-quality measurements, such as the forward link's frame error rate, the number of dropped calls, or the Power Measurement Report Message (PMRM), can be used, alone or in combination, instead of or in addition to the pilot fraction of the forward link to determine whether call blocking should be initiated. Determining whether call blocking should be initiated using one of the other call-quality measurements is performed in a similar manner as for the pilot fraction. Initiating call blocking using several call-quality measurements involves initiating call blocking when any one of the call-quality measurements indicates that call blocking should be initiated. Alternatively, call blocking can be initiated when several of the call quality measurements indicate that call blocking should be initiated.

IPC: H02J7/00
Filed: 1999-03-30
Abstract: A method and apparatus are provided for converting the terminal voltage of a battery so that one or more operations, such as shut-down or save-to-disk, begin at the appropriate point on the discharge curve for various cell chemistries. A control circuit is provided for triggering end-of-discharge operations based on various predetermined points, such as remaining capacity, voltage, temperature, and safety for devices which utilise a predetermined terminal voltage measurement to trigger one or more operations. The control circuit modulates the terminal voltage of the battery to a value which substantially matches the predetermined terminal voltage threshold of the device upon reaching a predetermined point, thereby successfully triggering operations at the appropriate time. The control circuitry can also modulate the terminal voltage to maintain it above the threshold to delay triggering of one or more operations. The method and apparatus allow devices designed for use with cells of a certain chemistry to be able to suspend operations without losing data or to delay operations to avoid wasting battery capacity when used with cell chemistries different from those for which the devices were designed.

Abstract: Line circuits (LC1, LC2 ... LCn) can be supplied with a first voltage (VBAT) or a second voltage (VB) of a lower absolute value. At least the second voltage is variable. The line voltages of at least active line circuits are measured, and possible values for the second voltage (VB) are prognosticated.  It is determined which line circuits can be supplied with the respective possible value, and the power consumption of those line circuits is calculated using each possible value. For the line circuits which cannot be so supplied, the power consumption is calculated using the first voltage (VBAT). For each possible value prognosticated for the second voltage (VB), the total power consumptions are summed, and the value that gives the lowest total power consumption, is selected as the second voltage (VB). The line circuits are then supplied with the first voltage (VBAT) or the selected second voltage (VB).
