Embodiment Construction

[0066] Benefiting from the development and improvement of communication technology, the current coverage of 2 / 3 / 4G (second, third, and fourth generation mobile communication technology) networks has been relatively complete, but with the advancement of 5G network construction, and the wireless signal of the 5G network itself characteristics, which put forward higher requirements for indoor coverage of 5G networks. For the communication requirements of the 5G network, an indoor distribution system needs to deploy a large number of slave nodes. In this case, how to improve the efficiency of establishing communication between master and slave nodes becomes an urgent problem to be solved.

[0067] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of the...

Abstract

An embodiment of the present application provides a communication interaction method, a master node, a slave node, an indoor distribution system, and a medium, wherein the communication interaction method includes: searching the network based on a preset frequency band to determine the frequency point of a base station; controlling the communication of the master node The frequency point is consistent with the frequency point of the base station, so that the master node accesses the base station; establishes a communication connection with the slave node accessing the base station through a handshake process, and the communication of the slave node accessing the base station The frequency point is the same as the frequency point of the base station; message communication is performed with the slave node establishing the communication connection. The embodiment of the present application can effectively guarantee the synchronization between the master node and the slave nodes, and improve the communication establishment efficiency between the master node and the slave nodes.

Description

technical field [0001] The embodiment of the present application relates to the technical field of communication, and specifically relates to a communication interaction method, a master node, a slave node, an indoor distribution system, and a medium. Background technique [0002] In indoor environments such as large buildings, underground shopping malls, and underground parking lots, mobile communication signals are weak, which can easily form blind and shadow areas of mobile communication, resulting in mobile phones and other terminals that use mobile communication signals cannot be used normally. The indoor distribution system can be used to improve the mobile communication signal in the indoor environment. The indoor distribution system can evenly distribute the mobile communication signal of the source (such as the base station) in every corner of the room, so as to ensure ideal signal coverage in the indoor environment. [0003] The indoor distribution system mainly in...
