Abstract: A method implemented by a MS for controlling handover of the MS from a source cell of a source RAN operating in PS domain to a target cell of a target RAN operating in PS domain where the target RAN supports MOCN. The method includes receiving SI transmitted by a node of the source RAN. The SI includes a selected PLMN, LAC of the target cell, and RAC of the target cell. The MS executes handover to the target RAN. A target RAI is determined using the selected PLMN, LAC of the target cell, and RAC of the target cell from the SI transmitted by the node of the source RAN. The target RAI is compared to a registered RAI of the MS. The MS determines whether a RAU is needed in the target RAN based on the comparison of the target RAI to the registered RAI.

Abstract: A wireless communication device can provide an indication that its registration in a circuit-switched domain of a network is intended only for a short message service that is included in or accompanies a registration request, such as a combined registration for both the CS domain and a packet-switched (PS) domain. The device can also change a conventional order of its domain registrations, e.g., by performing a PS- domain registration before a CS-domain registration, when it will send SMS messages over the PS domain. The device can indicate its intention to use or support for SMS over the PS domain and/or be informed about network support for SMS over the PS domain before the UE attempts a network registration.

Abstract: A switched mode power supply (SMPS) comprising a feedback unit, voltage feed forward (VFF) compensation signal generator (1211) and a transient detector (701) is disclosed. A VFF compensation signal is only applied to the output of the feedback unit when a transient is detected by the transient detector (701) on the input voltage of the SMPS, thereby a saving power and computation time. The transient detector (701) comprises a first comparator (402) to detect that a positive transient has occurred if a difference signal is greater than a positive threshold level Cb1Q); a second comparator (403) to determine if the difference signal is within a predetermined range of positive values and output a result that indicates if the difference signal is within the predetermined range of positive values; and a first calculator (405) to detect that a positive transient has occurred if, out of a first predetermined number (N1) of consecutive results of the output of the second comparator (403), there is at least a second predetermined number (X1) of results indicating that the difference signal is within the predetermined range of positive values. The transient detector comprises further features for similarly detecting a negative transient. The transient detector (701) is particularly good at dealing with measurement noise and light load induced noise.

Abstract: A mobile station decreases its transmit bit rate in response to a determination that its transmit power has exceeded an alarm-power threshold. The mobile station increases its bit rate in response to a determination that its transmit power is below a lower-power threshold. Lower-power threshold and alarm-power threshold delays can be employed to prevent ping-pong effects and avoid unnecessary throughput degradation. A dynamic lower-power threshold can be employed in which the mobile station estimates or predicts its transmit power if it were to increase its transmit bit rate and increases its transmit bit rate only if this can be performed without exceeding the alarm-power threshold.
