  • Mobile terminals may also be referred to as "pervasive computing" devices.
  • Fig. 1 is a block diagram of a typical mobile terminal 1 0.
  • the mobile terminal 1 0 includes an antenna 1 2, a receiver 1 6 and a transmitter
  • the antenna 1 2 is configured to send and receive radio signals between the mobile terminal 1 0 and a wireless network (not shown), including mobile telecommunica- tion systems such as private telecommunication systems (such as digital wireless office systems or other home or base systems) and public mobile telecommunication systems (such as public land mobile networks) .
  • the antenna 1 2 is connected to a duplex filter 1 4 which enables the receiver 1 6 and the transmitter 1 8 to receive and broadcast (respectively) on the same antenna 1 2.
  • the receiver 1 6 demodulates, demultiplexes and decodes the radio signals into one or more channels.
  • Such channels include a control channel and a traffic channel for speech or data.
  • the speech or data are delivered to the speaker 20 (or other output device, such as a modem or fax connector) .
  • the receiver 1 6 delivers messages from the control channel to the processor 22.
  • the processor 22 controls and coordinates the functioning of the mobile terminal ' 1 0 and is responsive to messages on the control channel using programs and data stored in the memory 24, so that the mobile terminal 1 0 can operate within the wireless network (not shown in Fig. 1 ) .
  • the processor 22 also controls the operation of the mobile terminal
  • the user interface 26 includes a keypad 28 as a user-input device and a display 30 to give the user information. Other devices are frequently included in the user interface 26, such as lights and special purpose buttons.
  • the processor 22 controls the operations of the transmitter 1 8 and the receiver 1 6 over control lines
  • the microphone 32 (or other data input device) receives speech signal input and converts the input into analog electrical signals.
  • the analog electrical signals are delivered to the transmitter 1 8.
  • the trans- mitter 1 8 converts the analog electrical signals into digital data, encodes the data with error detection and correction information and multiplexes this data with control messages from the processor 22.
