    摘要: The mobile station includes a system for using open channel time not needed during access to the wireless web. The mobile station monitors the use of the channel, and determines when the user is no longer transmitting or receiving information. Until the current network session terminates, the mobile station may operate in the background to either send or receive information with the network. Any action taken by the user would take priority over the background operations.

    摘要: A method for synchronizing communication between a transmitting unit (102) and a receiving unit (104) in a telecommunication system (100) includes calculating a reverse checksum for the received data. At the transmitting unit (102), data including a length indicator is serially transmitted. At the receiving unit (104), the data are received and stored in a buffer. A checksum is calculated beginning with the last-received data while maintaining a length count. When the checksum verifies and when the length count matches the transmitted length indicator, the received data is considered valid and communication is considered synchronized.
