Embodiment Construction

[0047] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0048] figure 2 The method of the present invention for omitting RLC acknowledgment status reporting is shown. Combine below figure 2 The method is described in detail.

[0049] Step 1: When the RLC layer on the network side transmits a set of ordered rlc-PDUs to the MAC layer on the network side, set the protocol parameter P and start the corresponding timer. The protocol parameter P may instruct the terminal (UE) to respond (acknowledgement / non-acknowledgement) to the received data from the network side (UTRAN). The timer is used to limit the retransmission time limit of the data packet. For example, when the network side has not received the status response report from the terminal when the timer time limit is reached, the previous data packet is automatically retransmitted.

[0050] Step 2: The MAC layer on the network side packages the rlc-PD...

Abstract

The invention discloses a method and system for omitting an RLC determination state report under a high-speed downlink packet access environment, which is capable of saving air-interface resources and increasing the uplink transmission efficiency. The invention adds an RLC layer report mechanism on an MAC layer based on the present protocol, which is used for reporting the reception situation of the MAC layer receiving high-speed downlink data. At the same time, a process for processing the report is added on the RLC layer and the determination state report is not processed. Compared with the prior technology, the terminal RLC layer need not respond the determination state report to the network side under an HSDPA environment, thereby saving the air-interface resources and ensuring that all data transmitted on air-interfaces are available data without filling bits, so as to increase the uplink transmission efficiency. The invention is applied in the mobile communication field.

Description

technical field [0001] The present invention relates to a data communication method and system under a high-speed downlink packet access environment (HSDPA, High Speed ​​Downlink PacketAccess), in particular to a kind of omitting RLC (RadioLink Control, radio link control) confirmation status report under the HSDPA environment methods and systems. Background technique [0002] In the existing third-generation mobile communication, figure 1 A staged process of data communication under the HSDPA environment is shown. Combine below figure 1 Describe the existing HSDPA data processing process. [0003] The first step: when the network side RLC layer transmits a group of ordered RLC protocol data units (rlc-PDUs) to the network side MAC (Media Access Control, media access control) layer, set the protocol parameter Polling bit (hereinafter referred to as P) and start the corresponding timer. The protocol parameter P may instruct the terminal (UE) to respond (acknowledgement / n...
