Problems solved by technology

[0023] However, similar to Solution 1, Solution 2 cannot meet the different QoS requirements of different services; moreover, setting a timer for each V(Q) is more complicated to implement; in addition, the setting of the timer value is different from the application scenario. relationship, the setting is more difficult, such as the call between the computer (PC) and the MS, the part of the delay that the MS should bear is difficult to estimate

Embodiment Construction

[0061] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0062] The basic idea of ​​the method for receiving services proposed by the present invention is: the RLC data block buffer in the receiving window is divided into at least two sub-areas, and the receiving mechanism is set for each sub-area, and in each sub-area, the receiver follows the set The reception mechanism performs reception of RLC data blocks.

[0063] Referring to the embodiment shown in Figure 4, the RLC data block buffer from V(Q) to V(R)-1 in the receiving window in the existing protocol can be divided into adjustable receiving regions RS by setting the sub-receiving window length WS' and a sub-receiving window of length WS', and use different receiving mechanisms in the adjustable receiving area and the sub-receiving window. For example...

Abstract

The invention discloses a method of sending and receiving business, the method of sending business is: separate the radio link control (RLC) block data buffer area in send window into no less than two sub-area, and set up transmit mechanism for every sub-area, in every sub-area the transmit leg send the RLC block data according to the set transmit mechanism; the method of receiving business is: separate the radio link control (RLC) block data buffer area in receive window into no less than two sub-area, and set up receiving mechanism for every sub-area, in every sub-area the receiver accept the RLC block data according to the set receiving mechanism. The method provided by this invention can meet the different quality of service requirements of different businesses, reduce business time delay, and reduce waste of wireless resources.

Description

technical field [0001] The invention relates to wireless transmission technology, in particular to methods for sending and receiving services. Background technique [0002] In the general packet radio service (GPRS), the radio link control (Radio Link Control, RLC) automatic repeat request (Automatic Repeat ReQuest, ARQ) function supports three operation modes, namely: RLC acknowledged mode (RLC acknowledged mode), RLC unacknowledged mode (RLC unacknowledged mode) and RLC non-persistent mode (RLC non-persistent mode). The RLC acknowledge mode retransmits RLC data blocks to obtain high reliability, the RLC non-acknowledge mode does not retransmit RLC data blocks, and the RLC non-persistent mode uses non-exhaustive retransmission of RLC data blocks. [0003] For multimedia broadcast / multicast service (Multimedia Broadcast / Multicast Service, MBMS) transmission, the RLC non-persistent mode is usually adopted. The bearer entity of MBMS consists of an RLC sending endpoint on the...
