Abstract
A method for radio link control in a mobile wireless communication device. The mobile wireless device transmits a sequence of service requests to establish radio resources with a wireless communication network for a data packet in a pending data buffer. When no radio resources are allocated in response to the transmitted sequence of service requests, the mobile wireless device sets a minimum threshold for the pending data buffer, discards all pending data packets above the minimum threshold and discards the oldest pending data packet. The mobile wireless device repeats transmitting and discarding until a radio resource is allocated or the pending data packet buffer is empty. A retry interval between successive service requests is increased after transmitting each sequence of service requests until reaching a maximum retry interval value.
