A method of connection setup in mobile wireless data communications systems is disclosed where the connection setup time is decreased for delay-sensitive communications sessions relative to the normal connection setup time for confidence-dependent communications sessions. This is achieved by performing some of the connection set-up steps for delay-sensitive communications sessions after successfully demodulating a smaller number of indications identifying an access terminal's desired serving resource than would be demodulated in the case of a confidence-dependent communication session prior to performing the same connection set-up steps.

Method and system for reducing connection set-up time

A method and system for connection management in a wireless data network, such as a 1xEV-DO network adds connections to new network sectors upon receipt of a connection request from an active terminal, but removes data connections that the active terminal requests to be dropped only after confirmation from the active terminal that a channel allocation message has been received and applied. The active network maintains an active set of connections that is at least as large as the active set maintained by the active terminal and does not initiate a connection termination if no confirmation of the channel allocation message is received. This allows for a reduction in the number of dropped connections.

An apparatus and method for power control in a cellular basestation transmitter with multiple digital carrier channels. Each digital carrier signal is attenuated by a digital power control circuit under the control of a microcontroller, the amount of attenuation varying according to the number of active channels. The attenuated digital signals are combined and converted to an analog signal by a digital to analog converter, and the analog signal is amplified by an analog power control circuit also under control of the microcontroller. The combined digital signal may be clipped to reduce the signal peaks, the amount of clipping varying according to the number of active channels.
