The algorithm disclosed here is a method for a mobile station device to select a network for wireless communications in a way that takes advantage of the most favorable roaming agreements between operators. The exemplary algorithm provides the flexibility to select between 3GPP2 (1×RTT and EVDO) technologies and 3GPP (LTE/GSM/UMTS) technologies as well as specific operators' networks for domestic and international roaming. The proposed algorithm allows the operator to optimize roaming agreements in different markets and maximize revenue from roaming.

The techniques disclosed here enable a mobile station device having a plurality of subscriber identities to select an identity for registration with a network for wireless communications in a way that takes advantage of the most favorable roaming agreements between operators. The identity selection algorithm, for example, provides the flexibility to select amongst mobile station subscriber identities of 3GPP2 (1×RTT, EVDO) access technologies and 3GPP (LTE/GSM/UMTS) access technologies as well as specific operators' networks for domestic and international roaming. The exemplary algorithms allow the operator to optimize roaming agreements in different markets and maximize revenue from the roaming of its customers.
摘要:
A mobile station automatically determines a country in which mobile station is or will operate from readily available information, without direct assistance from the local wireless communication network. A multimode mobile station, for example, capable of both 3GPP and CDMA operation, is programmed to detect both MCC type system identifiers (from 3GPP protocol) and SID type system identifiers (from CDMA protocol) and map both types of identifiers to country identifications. However, at some locations, the SID may not uniquely map to a country. In this later case, an exemplary mobile station may identify the country by determining a local time (LTM) offset and mapping a combination of the SID obtained at the current location and the LTM offset to an identification of the country. The mobile station may use the country determination to help select a preferred network or to enable a location based device feature.

摘要:
An automatic remote control device and method which compensates for ambient, environmental noise changes and sudden changes in program material volume. The microphones and circuitry associated with the volume control apparatus are located in an autonomous, preferably portable, remote control unit that will work with any existing audio/video device that is configured to respond to a remote control input. In one embodiment, the remote control device comprises a microprocessor, at least one directional microphone for receiving a sound level emitted from a sound-emitting device, and at least one omni-directional microphone for receiving the total noise level in the vicinity of the remote control device. The microprocessor located in the remote control device utilizes the received sound level and the total received noise level to calculate a reference sound-to-noise ratio. If a volume up/down control is pressed by the operator, the remote control device sends the appropriate signal to the sound-emitting device to increase or decrease the sound level, and a new reference sound-to-noise ratio is calculated. If the volume up/down control has not been used, a timed polling loop periodically measures the sound level and the total received noise level so as to calculate a current sound-to-noise ratio and to determine whether the sound-to-noise ratio has changed. If the sound-to-noise ratio has changed, then the remote control device sends the appropriate signal to the sound-emitting device to adjust the sound level so that the original sound-to-noise ratio is maintained. Hysteresis, in which the device determines whether a pre-determined amount of time has passed since the device last adjusted the sound level, is preferably utilized to prevent continuous fluctuations of the sound.

A method may include determining a power level of a signal and a temperature level of a transmitter originating the signal. At least one of the power and temperature levels may be compared to a lookup table containing predistortion coefficients. The method is capable of predistorting a signal based on the comparison. An apparatus is disclosed in relation to the method.

A power amplifier system uses adaptive distribution of signals through an amplifier architecture of parallel amplifier stages. For example, the power amplifier system can adjust the operation of individual amplifier stages in the amplifier arrangement, for example to reduce power handling capability of the amplifier stages based on information of the signal to be amplified by the amplifier arrangement, such as the power level. To take advantage of the adjusted operation of the amplifier stages, the power amplifier system uses a variable power divider to reapportion the input signal power among the amplifier stages and at least one variable combiner to adaptively combine amplified signals from the amplifier stages in changing proportions. As such, the power amplifier system is reconfigurable and/or can adapt to changing conditions to provide improved performance and/or efficiency.
摘要:
A signal amplification system involves transforming at least one signal to be amplified into at least one transformed signal which is amplified and the resulting amplified transformed signal(s) can be used to produce a version(s) of the at least one original signal. The at least one transformed signal can be produced from the at least one original signal by using the at least one original signal to amplitude and/or angle (phase or frequency) modulate the at least one original signal. After amplification of the at least one transformed signal, the resulting at least one amplified transformed signal is de-modulated to produce a version(s) of the at least one signal. In transforming the at least one original signal to produce the at least one transformed signal, the at least one original signal is transformed into a more desirable form, such as a more power efficient form, for amplification. By amplifying the at least one transformed signal, more efficient and/or less costly amplifier(s) can be used to amplify the at least one signal in a linear fashion. Depending on the embodiment, at least one signal to be amplified can be transformed into at least one transformed signal by combining offset versions of the at least one original signal to produce the at least one transformed signal having the energy of the at least one signal spread in time and/or to produce the at least one transformed signal having a reduced peak to average power ratio(s)(PAR). Multiple signals to be amplified can be transformed into at least one transformed signal by combining the multiple signals, for example to produce the at least one transformed signal having a reduced peak to average power ratio(s) (PARs). After the at least one transformed signal is amplified, the resulting signal(s) can be de-modulated, inversely transformed, de-spread or reconstructed to recover a version(s) of the original signal(s).
