Abstract
The present invention relates to a method for reestablishing wireless communication between a radio access network (RAN1) and a mobile station (MS1), an apparatus (RNC1) used for implementing the method as well as a radio access network (RAN1) including such an apparatus. A downlink radio failure affecting a first set of radio bearers (RB1, RB2) including at least two radio bearers (RB1, RB2) assigned for communicating user data between the radio access network (RAN1) and the mobile station (MS1) is detected. A second set of radio bearers (RB1) for communicating user data is defined, excluding the radio bearer (RB2) having the highest downlink bit rate in the first set of radio bearers (RB1, RB2). Communication reestablishment is initiated using the second set of radio bearers (RB1).
