NODE B WHICH FACILITATES SELECTIVE PURGING OF ITS BUFFERS

摘要

A system and method are disclosed for managing packet data units (PDUs) received by a Node B from a radio network controller (RNC) and stored in a buffer of the Node B while awaiting transmission to a user equipment (UE). A purge triggering event with respect to PDUs associated with the UE is detected at the RNC and the RNC transmits a purge message to the Node B requesting a purge of at least a portion of the PDUs associated with the UE from the Node B's buffer. The requested PDUs are then deleted from the Node B's buffer.
