Problems solved by technology

This method can indeed improve cell coverage in some application scenarios, but it also has obvious shortcomings. The proposed distance calculation from the base station to the terminal is carried out through two-dimensional coordinate information (x1, y1) and (x2, y2) , does not consider the influence of height on distanc

Embodiment Construction

[0048] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0049] Such as Figure 1-3 As shown, the long-distance access method includes:

[0050] Step 1, storing LTE base station location information and cell information in the terminal;

[0051] Step 11, correspondingly store the pre-acquired LTE base station location information and the LTE base station identity mark in the terminal, and store the cell identity mark in the terminal at the same time, and then configure the timing advance protection time T for the terminal prt , configure the near-point threshold T thrld ;

[0052] Step 12, the terminal selects a cell through cell selection, reselection or handover, and reads the cell identity;

[0053] Step 13, the terminal queries the location information of the LTE base station through the LTE base station identity, and then obtains the location information of the terminal in the cell corresponding to ...

Abstract

The invention belongs to the technical field of LTE wireless communication, and particularly relates to a long-distance access method based on an LTE wireless communication technology. The method comprises the following steps: 1, storing LTE base station position information and community information in a terminal; 2, calculating a spatial linear distance between the terminal and the LTE base station by using the obtained information through the terminal; and 3, calculating the round-trip delay time by utilizing the space linear distance, and then calculating the timing advance value. An ultra-long-distance LTE community coverage and access process is realized, and an LTE system can obtain a maximum coverage effect with low time-frequency resource overhead.

Description

technical field [0001] The invention belongs to the technical field of LTE wireless communication, and in particular relates to a long-distance access method based on the LTE wireless communication technology. Background technique [0002] LTE (Long Term Evolution) wireless communication technology, because of its high data transmission rate and high spectrum efficiency, has been widely deployed around the world and applied in various fields and scenarios. Some fields of LTE application, such as ground-to-air communication, that is, the communication between the ground base station and the air plane, have higher requirements for the terminal access distance, such as requiring the aircraft to still be able to access the base station at 130KM or even farther away. This is difficult for conventional LTE base stations and terminals to achieve. Table 1 shows the preamble format and supported cell radius of each PRACH (Physical Random Access Channel) of LTE under the 3GPP specific...
