Method for configuring resorting buffer size of non-confirmed mode

Abstract

The present invention discloses a method of configuring the size of an unacknowledged mode reorder buffer and is created to resolve the problem that the prior art cannot utilize the high-speed downlink packet access characteristic to send data. The method includes three steps. Firstly, a terminal sends a radio resource control connection establishment request signal carrying the total buffer sizeparameter cells of the acknowledged mode radio link control layer and the high-speed media access control layer to a radio network controller; secondly, the radio network controller decides to use thehigh-speed downlink packet access characteristic and, according to the current signal data configuration and the service data configuration, computes the reorder buffer size parameter of the unacknowledged mode high-speed media access control layer; finally, the reorder buffer size parameter of the unacknowledged mode high-speed media access control layer is sent to the node B by means of a radiolink establishment request signal. The present invention realizes the mapping of signal radio barrier in a high-speed downlink charging channel and data transmission according to the high-speed downlinkpacket access characteristic.

Description

technical field [0001] The invention relates to a high-speed media access control layer in a wireless communication system, in particular to a method for configuring the reordering buffer size (MAC-hs Reordering Buffer Size for UM) of a non-acknowledged mode high-speed media access control layer. Background technique [0002] Total RLC AM and MAC-hs buffer size (the total buffer size of the confirmed mode radio link control layer and the high-speed media access control layer) parameter, which describes the terminal's RLC AM (acknowledged mode radio link control layer) transceiver buffer and MAC - The total buffer size of hs (high-speed media access control layer) reordering buffer, that is, the maximum total buffer size of all RLC AM entities and all MAC-hs reordering entities supported by the terminal. The total cache is dynamically shared and multiplexed by the RLC AM entity and the MAC-hs reordering entity. For example, when the MAC-hs reordering entity is not used, the ...

Problems solved by technology

[0006] When using the high-speed downlink packet access feature, the MAC-hs Reordering Buffer Size for UM needs to be known by Node B, so that Node B can control the downlink data volume of signaling data and business data in the unacknowledged mode using the high-speed downlink packet access feature , to avoid buffer overflow when the terminal receives the corresponding data, and ensure that the corresponding data received by the terminal is normal and not lost. However, in the existing protocol, TotalRLC AM cannot be carried in the "radio resource control connection establishment request" signaling and MAC-hs buffer size parameter information, the process of mapping the signaling radio bearer to the high-speed downlink shared channel cannot be realized, and the protocol explicitly allows the signaling radio bearer to be mapped to the high-speed downlink shared channel, and the high-speed downlink packet access feature for data transmission cannot be completed Function
