Abstract
There is provided a method in a first base (Node_B_S) station adapted to receive media access control layer packet data units (MAC-d; PDU) from a radio network controller (RNC) relating to at least a traffic flow relating to a given user entity (UE_Q) and forwarding (MAC-hs/MAC-ehs) such packet data units to said user entity. The transmission to the given user entity is adapted to be potentially handed over to at least a second radio base station (Node B_T), the method being characterized in the following steps:—the first base station (Node_B_S) continuously updating () at least a data structure (UNACK_MACD_CNT) relating to media access control layer packet data units (MAC-d PDU's) of a priority queue of the user entity, which packet data units are recently transmitted from a protocol layer (RLC) in the radio network controller (RNC RLC) whereby at least some of said packet data units may not be received by a corresponding protocol layer (RLC) in the user entity (UE_Q) yet,—the first base station, upon receiving a predetermined signal (UNACK_MACD_REQ ()) from the radio network controller requesting the data structure, transmitting () a current value of said data structure (UNACK_MACD_CNT) to the radio network controller (RNC). Also, a method for a radio network controller is provided and corresponding entities.
