Uplink maximum bit rate control

Abstract

An improved Maximum Bit Rate (MBR) control in a radio packet communication network is disclosed. According to the invention, a User Equipment (UE) in the network evaluates each packet being added to a transmission buffer, based on a MBR level, considering each evaluated packet as being either a conformant or a non-conformant packet, wherein a packet is considered to be non-conformant if it, at the time for the evaluation, is intended to be dropped or delayed. Further, the UE creates a Buffer Status Report (BSR), including data volume information relating only to packets in the transmission buffer being considered as conformant packets, and transmits the BSR to a node performing Medium Access Control (MAC) in the network.

Description

technical field [0001] The invention relates to uplink maximum bit rate control in a wireless packet communication network. Background technique [0002] Specifically, the present invention relates to a maximum bit rate (MBR) and an integrated maximum bit rate (AMBR) of a radio bearer in a wireless communication system, and the wireless communication system may be Long Term Evolution (LTE) of 3GPP or Universal Mobile Telecommunications System (UMTS), etc. . [0003] In current quality of service (QoS) packet-based networks, data (and signaling) at different QoS levels may have different data loss rates, different delay characteristics and / or different throughputs. [0004] Radio bearer is a service provided by the second layer of the Open System Interconnection (OSI) model in Wideband Code Division Multiple Access (WCDMA) 3G technology, and is used for user equipment (UE) and UMTS terrestrial radio access network (UTRAN) to transfer user data between. [0005] Data of the...

Problems solved by technology

[0027] In the prior art, there is a problem of "permission loss" in the implementation scheme of MBR restriction

This problem arises when the UE reports in a Buffer Status Report that it has a certain number of bytes stored in its transmit buffer, and usually receives a response from the network that allows the UE to send the specified number of bytes resource allocation grant of bytes; then, if the UE enforces MBR restrictions when sending, the UE will most likely drop packets to avoid the rate exceeding the MBR limit; therefore, in this case, the UE will drop what it has requested and has packets that are granted transmission resources, as a result the entire resource allocation grant will not be utilized, i.e. wireless transmission resources are wasted
