20120008573 | RADIO RESOURCE SIGNALING DURING NETWORK CONGESTION IN A MOBILE WIRELESS DEVICE - 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.

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. | 01-12-2012 |
20120033554 | METHOD AND APPARATUS FOR RADIO LINK CONTROL DURING NETWORK CONGESTION IN A MOBILE WIRELESS DEVICE - A method and apparatus for radio link control during network congestion in a mobile wireless communication device connected to a radio network subsystem in a wireless cellular network. The mobile wireless communication device detects a pending uplink control message. The mobile wireless communication device determines that an uplink channel on which the pending uplink control message is to be sent has insufficient bandwidth for uplink transmission. After waiting a congestion delay time interval, the mobile wireless communication device sends the pending uplink control message on an uplink signaling channel instead of on the uplink channel. In some embodiments, the uplink channel is associated with a radio access bearer and the uplink signaling channel is associated with a signaling radio bearer. | 02-09-2012 |
