Abstract
The invention discloses a method and equipment for discarding SDUs (service data units) under a radio link control unacknowledged mode (RLCUM). The method comprises the following steps: an RLC entity receives the SDUs sent by an upper layer, and records the time point for receiving the SDUs; the RLC entity detects the received SDUs which are not sent; and if the difference between the current time and the time point for receiving the unsent SDUs exceeds the corresponding time length set by a discard timer, the unsent SDUs are discarded. In the embodiment of the invention, the RLC entity initiatively judges whether the SDUs are discarded according to the time point for receiving the SDUs and the time length set by the discard timer, thus avoiding frequent interaction of SDU discard instructions between the RLC entity and a PDCP (packet data convergence protocol) entity or interaction of the situations for sending the SDUs, reducing memory expenditures and interactive processing expenditures between layers, and improving processing efficiency.
Description
Technical field
The present invention relates to the communications field, relate in particular to the method and apparatus that SDU abandons under a kind of radio link control UM pattern.
Background technology
Different Q CI(QoS Class Identifier, qos class sign) business, its data are surrounded by propagation delay time requirement separately.When Data Radio Bearer is set up, RRC(Radio Resource Control, radio resource control) is PDCP(Packet Data Convergence Protocol, PDCP) physical arrangements SDU(Service Data Unit, Service Data Unit) abandons timer duration, realize regularly discard of SDU by the PDCP entity, do not overflow to guarantee data transmission delay and interface-free resources utilization ratio and buffering area.
At RLC(Radio Link Control, radio link control) under the AM pattern (affirmation mode), according to the PDCP protocol function, the PDCP entity need be stored each SDU, need know that when carrying out SDU abandons, therefore the startup of PDCP entity abandons timer, and timer expiry then PDCP entity abandons the SDU that stores, and notice RLC entity abandons this SDU.
But in the non-affirmation of RLC UM() during pattern, under non-switching, the upright state of reconstruction, the PDCP entity does not originally need to preserve each packet, but in order to realize regularly discard, need store SDU when receiving each SDU receives information, starts and abandon timer, the PDCP entity need notify the RLC entity to abandon this SDU when the timer expiry of each SDU, perhaps when sending each SDU, notify the PDCP entity to abandon corresponding SDU by the RLC entity, if abandon timer expiry simultaneously, PDCP entity notice RLC entity abandons corresponding SDU.
Concrete, the PDCP entity receives that UM SDU(is the SDU that receives under the RLC UM pattern in the existing scheme) after handling process as shown in Figure 1, comprising:
1.1.PDCP entity is received UM SDU;
