Embodiment

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

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

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

[0039] Step 3: Construct a segmented scene using a test terminal.

[0040] When the gateway station is running, due to the limited downlink bandwidth, the downlink rate has a maximum value. Before constructing the segmentation scenario, it is necessary to determine the maximum downlink rate V of the gateway station. max. Although the maximum downlink rate under the ideal state can be calculated according to the downlink bandwidth of the system, due to the different resource allocation strategies implemented by each manufacturer, the maximum downlink rate that the gateway station can achieve during operation is unknow...

Abstract

The invention discloses a method and a device for constructing a downlink segmentation scene of an RLC layer of a test gateway station. The method comprises the following steps: 1, detecting the maximum downlink rate of the gateway station during operation; 2, calculating a background rate, and obtaining a segmentation threshold value; 3, constructing a segmented scene by using the test terminal. The system comprises a multi-terminal simulator, a test server and a tested gateway station. The multi-terminal simulator is in signal connection with the test server through a control interface, the multi-terminal simulator is in signal connection with the tested gateway station through an air interface, and the test server is in signal connection with the tested gateway station through an N6 interface. According to the invention, the scene of RLC layer segmentation of the gateway station can be constructed, so that the test of the segmentation function of the RLC layer of the gateway station is realized, and the problems that the existing test method cannot perform test design for the protocol function of the RLC layer and cannot cover various scenes of downlink segmentation of the RLC layer are well solved.

Description

technical field [0001] The invention relates to the field of satellite communication, in particular to a method and a device for constructing and testing a gateway station RLC layer downlink segmentation scene. Background technique [0002] RLC is the radio link control layer in the satellite mobile communication protocol. The mobile terminal and the RLC of the gateway station are peer entities at both ends of the communication. When the sender sends data, if the complete data cannot be sent out 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 one by one. When sending downlink data, the gateway station 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 lead to ...
