Embodiment

[0036] like figure 1 As shown, a method for constructing a downlink segment scenario of a test gateway RLC layer described in this embodiment includes the following steps:

[0037] Step 1: Detect the maximum downlink rate when the gateway is running;

[0038] Step 2: Calculate the background rate, and obtain the segmentation threshold from this;

[0039] Step 3: Use the test terminal to construct a segmented scenario.

[0040] When the gateway is running, due to the limited downlink bandwidth, the downlink rate has a maximum value. Before constructing a segmented scenario, it is necessary to determine the maximum downlink rate V of the gateway. max. Although the maximum downlink rate in the ideal state can be calculated according to the downlink bandwidth of the system, the maximum downlink rate that the gateway can achieve during operation is unknown due to the different resource allocation strategies implemented by various manufacturers. Terminal emulators and test serve...

Abstract

The invention discloses a method and a device for constructing a downlink segment scenario of a test gateway station RLC layer. The method includes the following steps: Step 1: detect the maximum downlink rate when the gateway station is running; Step 2: calculate the background rate, And thus obtain the segmentation threshold; Step 3: use the test terminal to construct a segmentation scene; the system includes a multi-terminal simulator, a test server and a tested gateway station, and the multi-terminal simulator and the test server realize signal connection through a control interface , the multi-terminal simulator realizes the signal connection with the gateway under test through the air interface, and the signal connection between the test server and the gateway under test is realized through the N6 interface. The invention can construct a scene of segmentation of the RLC layer of the gateway station, and then realizes the test of the segmentation function of the RLC layer of the gateway station, and solves the problem that the existing test method cannot make a test design for the protocol function of the RLC layer. , the problem of various scenarios that cannot cover the downlink segment of the RLC layer.

Description

technical field [0001] The invention relates to the field of satellite communications, in particular to a method and a device for constructing a downlink segment scenario of an RLC layer of a test gateway. Background technique [0002] RLC is the radio link control layer in the satellite mobile communication protocol. The RLCs of the mobile terminal and the gateway are peer entities at both ends of the communication. When the sender sends data, if the entire data cannot be sent at one time due to the limitation of the underlying resources, the RLC layer will divide the data into several segments of suitable sending size, and then send them out in sequence. When the gateway station sends downlink data, it will decide whether to send the data in segments according to the downlink resources, the amount of data to be sent, the guaranteed data rate and other factors. Data segmentation is part of the communication protocol, and incorrect segmentation can cause a variety of probl...
