A method in a wireless communications device having a first protocol stack f or use with a first radio access technology and a second protocol stack for use with a second radio access technology, the first protocol stack comprising a reordering component associated with a first layer of the first protocol stack and arranged to implement a data reordering queue, the method for transitioning from the fir st radio access technology to the second radio access technology, the method comprising: determining that the device should transition from the first radio access technology to the second radio access technology; in response to determining that the devi ce should transition, determining that data is present in a reordering queue implement ed by the reordering component; sending the data present in the reordering queue to a second layer which is higher than the first layer; and attempting transitioning fro m the first radio access technology to the second radio access technology. |
