Embodiment 1

[0048] This preferred embodiment provides a method for configuring the uplink rate of the wireless access point based on backhaul network bandwidth detection for the scenario where the wireless access point in the flat network transmits data to the base station gateway through the backhaul network. The method controls the uplink transmission rate , so that it can be adapted to the available network bandwidth of the backhaul network, so as to achieve the most efficient data transmission.

[0049] This preferred embodiment is introduced by taking the WCDMA system as an example. The miniaturization of WCDMA base stations has caused changes in network element functions, interfaces and networking methods. In this preferred embodiment, a 3G Home NodeB (3G Home NodeB, HNB for short) is used as a wireless access point, which is connected to a 3G Home NodeB Gateway (3G HNB Gateway, HNB GW for short) through an Iuh interface. Aiming at the available bandwidth of the wired access networ...

Embodiment 2

[0056] image 3 It is a schematic diagram of an application scenario of a 3G home base station network system according to Embodiment 2 of the present invention, as shown in image 3 As shown, in the networking scenario of this preferred embodiment, the 3G home base station performs data interaction with the HNB GW through the backhaul network, and at the same time realizes the operation and maintenance data interaction with the TR-090 interface of the HMS. In actual networking, the maximum uplink transmission rate of the backhaul network can be limited by the adopted protocol standard and the contract with the cable broadband operator. Therefore, by matching the maximum uplink transmission rate of the 3G femtocell with the maximum uplink transmission rate of the wired broadband access network, the entire communication system can transmit uplink data most efficiently and avoid packet loss of the uplink data of the 3G femtocell.

Abstract

The invention discloses an uplink bandwidth configuring method and device. The method comprises the steps of acquiring the maximum uplink access rate supported by a backhaul network and configuring the maximum uplink transmission rate of a wireless access point according to the maximum uplink access rate supported by the backhaul network. According to the uplink bandwidth configuring method and device, the problem that according to relevant techniques, the uplink service rate of the backhaul network is not matched with the bandwidth of the backhaul network is solved, uplink data transmission efficiency is improved, and air interface resources are saved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for configuring an uplink bandwidth. Background technique [0002] At present, the miniaturization and flattening of base stations is a rapid development direction of mobile communication systems. In a flat network structure, a wireless access point usually exchanges data with a gateway through a backhaul network, such as an asymmetric digital subscriber line (ADSL for short), microwave, and Ethernet. The uplink rate of the backhaul network has a certain limit. For example, the typical uplink peak rate standard of the ADSL protocol standard is 896Kbps, 1.2Mbps, 3.5Mbps, etc., and the maximum uplink rate of the mobile communication system may be greater than the maximum bandwidth of the backhaul network, such as UMTS. The HSUPA service supports transport layer peak rates of 5.74 Mbps, 11.50 Mbps, and 23 Mbps in different versions of the 3rd Generation Partner...
