Embodiment Construction

[0047] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0048] figure 1 The flow chart of the first embodiment of the data transmission rate control method provided by the embodiment of the present invention, as shown in figure 1 As shown, the method includes:

[0049] S101. Receive terminal aggregation maximum bit rate information sent by the relay station;

[0050]When a UE connected to the RN needs to register or has other business needs on the public data network, it needs to establish or modify a bearer for the UE through the UE's Mobility Management Entity (MME). After that, the UE The MME sends an S1-AP message to the RN through the DeNB: a terminal context establishment request message, which includes the UE-AMBR information corresponding to the UE, and the RN can further obtain the corresponding uplink UE-AMBR through the UE-AMBR information information and down...

Abstract

The embodiment of the invention provides a data transmission rate control method, device and system. The method comprises the following steps: receiving user equipment (UE) aggregate maximum bit rate (AMBR) information sent by a relay node (RN); acquiring an uplink data transmission rate control value and a downlink data transmission rate control value of a link from the RN to a Donor E-UTRAN Node B (DeNB); and controlling the downlink data transmission rate of the link between the RN and the DeNB. The embodiment of the invention ensures that UE-AMBR control on radio resources of the link from the RN to the DeNB is realized, redundant data transfer in a Un port is reduced and the radio resources are saved.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a data transmission rate control method, device and system. Background technique [0002] In a traditional network, the wireless connection between a base station (E-UTRAN Node B; hereinafter referred to as eNB) and a terminal (User Equipment; hereinafter referred to as UE) is a direct wireless connection, that is, a single-hop network. With the development of communication technology, relay technology is introduced, that is, one or more relay stations (Relay Node; RN for short) are added between eNB and UE, and RN is responsible for making one or more wireless signals sent by eNB Forward, and finally reach the UE. Taking the simpler two-hop RN as an example, the wireless link between an eNB and UE is divided into two wireless links from eNB to RN and RN to UE, so that a link with poor quality can be replaced by two Better links for higher link capacity an...
