Abstract: A multi-mode mobile wireless communications device architecture (200) including an application layer (210), a services layer (220) interfacing the applications layer, a multi-mode layer (230) interfacing the service layer, and a hardware layer (240) interfacing the multi-mode layer. The multi-mode layer includes first and second interoperable radio access technologies, for example W-CDMA UMTS and GSM/GPRS technologies.

Abstract: A multi-mode wireless communication device (100) includes two separate receivers (130, 132) associated with two different radio access technologies and a multi-mode channel selection circuit (174). The first receiver (130) and second receiver (132) operate simultaneously to receive a first signal (150) on a first channel and a second signal (152) on a second channel respectively. The multi-mode channel selection circuit (174) then obtains from the first signal first cell selection information (950) and from the second signal second cell selection information (952). Then the multi-mode channel selection circuit (174) selects a suitable channel to camp on based on the first and second cell selection information (950, 952).

Abstract: A method of and apparatus for optimizing a minimum turn around time (MTAT) between (a) a reception by a first device of a first infrared data communication (IRDC) frame sent from a second device and (b) a transmission by the first device of a second IRDC frame to the second device. The MTAT value received from the second device is loaded into a storage device. The first IRDC frame from the second device is received, and a counter of the first device either resets upon reception of each of the plurality of characters of the first IRDC frame or increments when none of the plurality of characters are received. The first device transmits the second IRDC frame to the second device when the counter value reaches the MTAT value.

Abstract: A wireless communication apparatus (100) and communication method provides an audio-based call connection operation. For example, one method includes receiving an incoming call message (108) and receiving an input audio answer signal (120), such as a user's voice, in response to the incoming call message (108). This method includes detecting an amplitude or characteristic of the input audio answer signal (120) and sending an answer call message (126) based on the detected amplitude level of the input audio answer signal (120). In another embodiment, the process includes storing the input audio answer signal (120) as preconnection audio information (304b) and subsequently sending the preconnection audio information (304b) as a post connection greeting. For example, a user saying the word “hello,” completes the call without any additional greeting required.
