Patent number: 8688118Abstract: An access procedure for call re-establishment is provided. In a first method, a mobile station, in at least some instances of detecting radio link failure, attempts call re-establishment on multiple cells concurrently. In a second method, a mobile station performs a first random access channel procedure when the mobile station is not aware of at least two cells with enabled call re-establishment, and performs a second random access channel procedure when the mobile station is aware of at least two cells with enabled call re-establishment.Type: GrantFiled: August 28, 2009Date of Patent: April 1, 2014Assignee: BlackBerry LimitedInventors: Christopher Harris Snow, Nazih Almalki, Ayman Ahmed Abdel-Samad, Dinesh Kumar Arora

Patent number: 8634408Abstract: The present document relates to radio transmission. In particular, the present document relates to the single-slot dual transfer mode (DTM) available e.g. in GSM/GPRS/GERAN networks. A transmitter is described. The transmitter is configured to send circuit switched data over a traffic channel to a corresponding receiver, wherein the traffic channel is segmented into a plurality of frames. The transmitter if further configured to determine a vacant frame of the plurality of frames, wherein no circuit switched data is sent in the vacant frame due to discontinuous transmission; and to send packet switched data over the traffic channel using the vacant frame.Type: GrantFiled: December 4, 2009Date of Patent: January 21, 2014Assignee: BlackBerry LimitedInventors: Nazih Almalki, Christopher Harris Snow, Ayman Ahmed Abdel-Samad, Dinesh Kumar Arora
