Problems solved by technology

[0012] Since the current specification does not stipulate the method of selecting the super-domain type, and the existing technical processing methods do not analyze and select the super-domain type according to the actual packet loss situation, this will bring some problems, as can be seen from the above example: Improper selection of the super domain type will lead to a waste of PDU space, so that the status report that could have been carried on an AMD PDU is too large to be loaded due to improper selection of the super domain type, and can only be sent using the STATUS PDU; it is also possible As a result, one STATUS PDU can be completed, but due to the improper selection of the super domain type, multiple STATUS PDUs must be used to complete it, resulting in a greater waste of air interface resources

[0101] The first embodiment of the super domain type selection method of the present invention is to select according to different situations applicable to various types of super domains by analyzing the characteristics of the currently lost PDU information. The current PDU information feature is analyzed by obtaining the total number of lost PDUs and the number of lost PDU information blocks. These information are also required for the super-domain construction process after the super-domain type is selected.

[0102] The super domain type selection method in this embodiment includes such as Figure 4 The steps shown below combine Figure 4 Describe each step in detail.

[0103] Step S10: The RLC layer confirms the difference between the highest expected state variable VR(H) and the received state variable VR(R) of the mode entity.

[0104] Step S11: Obtain the current PDU loss information from the AM receiving buffer, mainly including: the number of lost PDU information bl...

Abstract

The invention discloses an over domain type selection method and a system for entities at an acknowledged mode of a wireless link control layer, thus small PDU space is occupied and air interface resources are saved. The technical scheme is as follows: the entities at the acknowledged mode of the wireless link control layer select an over domain type according to the actual condition of loss of data protocol data units of the current acknowledged mode. The invention is applied to the field of wireless communications.

Description

technical field [0001] The present invention relates to a method and a system for selecting a super-domain type when an air interface radio link control layer (RLC) of a third generation mobile communication system communicates using an acknowledgment mode (AM) entity, and in particular to a method for making the PDU space occupied by the RLC AM entity smaller Superdomain type selection method and system. Background technique [0002] The radio link control (RLC) sublayer of the air interface of the third generation mobile communication system includes three modes: transparent mode (TM), unacknowledged mode (UM) and acknowledged mode (AM). [0003] The sender of the two sides of the RLC AM communication uses AMD PDU (Acknowledged Mode Data Protocol Data Unit, Acknowledged Mode Data PDU) as the service data unit (SDU) for carrying and sending the upper layer, and sets the serial number (SN) for the AMD PDU, and cycles according to 0-4095 Incrementally, the receiver needs to ...
