An overview of third-generation wireless personal communications: a European perspective

Abstract: An overview of third-generation wireless personal communications is presented, and the challenges to meet its demands are examined. At the ITU level, the third generation is known as IMT-2000. In Europe, the third generation of wireless personal communications is known as UMTS. Special attention has been paid in giving a brief description of the research and development, standardization, and regulatory activities. The UMTS terrestrial radio access (UTRA) concept is presented. The different ACTS projects involved in making UMTS a success are introduced.

Packet radio system, and a terminal equipment for a packet radio system

Abstract: A packet radio system encapsulates data packets of external data networks by a point-to-point protocol PPP (Fig. 4A, 4B), and passes them through one or more sub-networks to a point which supports the protocol of the encapsulated data packet. In addition, a special radio link protocol of the packet radio network is required on the radio interface between a mobile data terminal equipment and a support node. PPP packets are encapsulated in data packets of said radio link protocol. The disadvantage of the arrangement is that the data packets of both the PPP protocol and the radio link protocol contain protocol-specific control fields, which reduces the transmission capacity of user information. Therefore, a PPP packet is compressed (Fig. 4C) before the encapsulation (Fig. 4D) by removing therefrom the unnecessary control fields. After having been transferred over the radio interface, the PPP packet is decompressed into its original format (Fig. 4F, 4G).

Shared channel structure, ARQ systems and methods

Abstract: A forward link design is provided employing CDMA (code division multiple access) technologies in which time division multiplexing is employed between data and control information on the forward link to service multiple users per slot Another forward link design employing CDMA (code division multiple access) technologies is provided in which code division multiplexing between data and control information is employed on the forward link to service multiple users per slot, which is preferably backwards compatible with legacy standards such as IS2000A A reverse link design is also provided

MAGIC: a motion gesture design tool

Abstract: Devices capable of gestural interaction through motion sensing are increasingly becoming available to consumers; however, motion gesture control has yet to appear outside of game consoles Interaction designers are frequently not expert in pattern recognition, which may be one reason for this lack of availability Another issue is how to effectively test gestures to ensure that they are not unintentionally activated by a user's normal movements during everyday usage We present MAGIC, a gesture design tool that addresses both of these issues, and detail the results of an evaluation

Transcoding method in a mobile communications system

Abstract: The present invention involves a method that allows a user of a Push-to-talk over Cellular PoC system to select more flexibly the mode of transmitting. By means of the present invention, the user of a PoC terminal (UE1) is able to send text during an ongoing PoC session to a PoC server (PS) which transcodes the text into speech before transmitting it to the other participants (UE2) of the PoC session. Additionally, the method allows a speech-to-text transcoding act, for example, in order to add subtitles to a video clip that is shown during a video-PoC session. Further, the method allows speech-to-speech transcoding in order to replace the sender's own speech with another speech or voice during a PoC session. In addition to the text-to-speech, speech-to-text and/or speech-to-speech transcoding, the PoC server (PS) may be arranged to translate the received data into another language and to send the translated data to the recipients or back to the sender.
