Claim:
1. A method for managing data packets in a buffer by a mobile device during periods of congestion in a wireless network, the method comprising: by the mobile device, while the buffer contains one or more pending data packets for transmission via a packet data protocol (PDP) context: determining whether one or more new pending data packets are received in the buffer; resetting a retry counter to a default maximum retry counter value, when the buffer receives one or more new pending data packets; determining whether the retry counter equals zero, when the buffer does not receive any new pending data packets; transmitting, to the wireless network, a service request for radio resource allocation for transmission via the PDP context of the one or more pending data packets in the buffer; decrementing the retry counter, when the mobile device is not allocated, in response to the service request, radio resources by which to transmit the one or more pending data packets in the buffer; repeating: until the mobile device is allocated radio resources by which to transmit the one or more pending data packets or the retry counter reaches zero; and discarding any pending data packets in the buffer, when the retry counter reaches zero.
