A temperature of a component within the portable computing device (PCD) may be monitored along with a parameter associated with the temperature. The parameter associated with temperature may be an operating frequency, transmission power, or a data flow rate. It is determined if the temperature has exceeded a threshold value. If the temperature has exceeded the threshold value, then the temperature is compared with a temperature set point and a first error value is then calculated based on the comparison. Next, a first optimum value of the parameter is determined based on the first error value. If the temperature is below or equal to the threshold value, then a present value of the parameter is compared with a desired threshold for the parameter and a second error value is calculated based on the comparison. A second optimum value of the parameter may be determined based on the second error value.

Method and system for optimizing performance of a PCD while mitigating thermal generation

An apparatus includes a first circuit and a second circuit sharing an instruction stream. A voltage controller circuit is configured to provide an operation voltage and at least one low-power voltage to the second circuit independent of a supply voltage of the first circuit in response to a sequence of the instruction stream. In another aspect, a method of operating a power management function is presented. The method includes providing an instruction stream for a first circuit and a second circuit and providing selectively an operation voltage and at least one low-power voltage to the second circuit independent of a supply voltage of the first circuit in response to a sequence of the instruction stream.

Processor power management responsive to a sequence of an instruction stream

A system, a method and an apparatus are described. The apparatus includes a modem that responds to a thermal mitigation request by invoking different levels of thermal mitigation for different concurrently active connections. In some instances, the modem may invoke thermal mitigation with respect to a first active connection and refrain from invoking thermal mitigation with respect to a second active connection maintained by the modem. The apparatus determines the first and second active connections based on subscriptions corresponding to subscriber identification modules, an identification of a power amplifier or group of power amplifiers responsible for a thermal issue in the modem. The selection of mitigation levels for each active connection and decisions to invoke mitigation on one connection while refraining from invoking mitigation on another connection may be based on priorities of the active connections, including quality of service related priorities.

Thermal mitigation in dual SIM dual active devices

A method and system for managing electrical current within a portable computing device ('PCD') includes assigning a priority to two or more communications supported by the PCD. A present level of a power supply for the PCD may be monitored by a communications power ('CP') manager module. Next, the CP manager module may determine if the two or more communications may be transmitted at the present level of the power supply. If the two or more communications cannot be transmitted at the present level of the power supply, then the CP manager module may determine if a timing of at least one of the communications may be adjusted. The CP manager module may also determine a theoretical power level adjustment for at least one of the communications. The two or more communications may be transmitted with any calculated timing off sets and power level adjustments.

Managing electrical current in a portable computing device when two or more communications overlap in drawing power during a transmission

An electrical current ('EC') manager module may assign a plurality of hardware elements of the PCD to one of two groups. The EC manager module may monitor individual electrical current levels of one of the groups as well as calculate an instantaneous electrical current level for the PCD based on a current charge status for the PCD. The EC manager module may then adjust operation of at least one hardware element to keep operation of the PCD below the calculated instantaneous electrical current level for the PCD. The EC manager module may estimate an electrical current level for one of the groups based on requests issued to hardware elements. The EC manager module may also compare the calculated instantaneous electrical current level to the monitored electrical current level. The calculated instantaneous electrical current level may be compared to minimum current levels listed in a table.

System and method for managing electrical current in a portable computing device

A portable telecommunications system (PTS) allows mobility and rapid deployment with minimal on-site configuration. PTS systems exchange multicast packets including location and identification information. A protocol manager sets up these communications channels, manages exchanges between PTS systems, and passes the data to or from internal system nodes. The PTS system detects when another PTS system is operating in close physical proximity and automatically perform actions, such as adjustment of transmission power level, to maintain service to the user base.

Auto-control of radiation power in a portable telecommunication system

A communications network and method for providing a voice message to a user of a mobile station (MS) in a network having a plurality of independent mobile systems, each independent mobile system including a Mobile Switching Center (MSC), Short Message Service Center (SMS-C) and Voice Message System (VMS), wherein each VMS is identified by a unique identifier code. A received voice message is stored in a VMS, and an SMS notification message is sent to the MS. Because each VMS is identified by a unique identifier code, the MS can retrieve a voice message by dialing the code contained in an SMS notification message, regardless of which independent mobile system is serving the MS at the time the voice message retrieval is requested.

Distributed fault-tolerant voice message system for independent mobile telephony networks

A portable telecommunications system (PTS), and discovery and update protocol provides an ad-hoc system in which PTS systems can detect one another over a wide area network (WAN). The system may be compact in a way that allows mobility and rapid deployment with minimal on-site configuration. PTS systems exchange multicast packets and peer-to-peer data exchanges. A protocol manager sets up these communications channels, manages exchanges between PTS systems, and passes the data to or from internal system nodes. The protocol manager also performs key oversight functions such as signaling to other systems that a PTS is joining or leaving the community, keeping track of which other PTS systems are in the community and active, and determining when data needs to be updated and exchanged.
