    摘要： In one illustrative example, methods and apparatus for use in buffering PTT voice communications are described. A mobile station sends a PTT voice communication request in a wireless communication network. Prior to receiving a floor grant in response to the PTT voice communication request, the mobile station receives voice input signals and buffers digital voice data corresponding to the voice input signals, where the digital voice data is produced by encoding and compressing the voice input signals. The mobile station receives the floor grant in response to the PTT voice communication request. Upon receipt of the floor grant, the mobile station retrieves the buffered digital voice data and continues to buffer digital voice data corresponding to the voice input signals, until all of the buffered digital voice data has been sent.

    摘要： An apparatus and method for telephony tone signal and character code generation for QWERTY keyboards includes a QWERTY style keyboard, a processor and a keyboard mode control software module. The QWERTY style keyboard has a plurality of letter keys, wherein each letter key is configured to generate a unique input signal. The processor is coupled to the keyboard and is configured to convert each unique input signal generated by the letter keys into a character code and/or a telephony tone signal. The keyboard mode control software module operates on the processor, and controls whether the processor converts the unique input signals from the letter keys into character codes or telephony tone signals.

    摘要： It has now been found that in some transmitter implementations which transmit multiple code channels, for example CDMA transmitters, the observed power for each code channel at the output relative to the other code channels is dependent upon the total transmit power due to non-linearities in the transmitter. Methods and apparatus are provided which use pre-set digital gains or digital gain adjustments to compensate for the non-linearities as a function of total transmit power such that at the output, the desired relative powers are observed.

    摘要： Methods and apparatus for expeditiously releasing network resources for a mobile station based on low battery and lost signal conditions are disclosed. The wireless network (104) receives a power down warning message from the mobile station (102) indicative of a low battery condition. The wireless network (104) then identifies whether a lost signal condition exists with the mobile station (102). In response to receiving the power down warning message and subsequently identifying the lost signal condition, the wireless network (104) causes network resources for the mobile station to be released. The wireless network (104) infers that the mobile station (102) has powered down due to low battery without enough time to send a power down registration to the wireless network (104).
