It should be noted that, in the case of no conflict, the features in the embodiments of the present application can be combined with each other.

In the following description, many specific details are set forth in order to fully understand the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative work shall fall within the protection scope of the embodiments of the present invention.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field of the embodiments of the present invention. The terminology used in the specification of the present invention herein is only for the purpose of describing specific embodiments, and is not intended to limit the embodiments of the present invention.

Please refer to Figure 1A and Figure 1B. The present invention provides an integrated indoor communication network, which is an integrated system with both communication and navigation and positioning functions. The indoor communication and conduction integrated network includes a communication signal source 100, a combiner/splitter 101 and a leakage unit 10. The leaky unit 10 includes a number of the leaky carriers 105 connected to the combiner/splitter 101, and connected to Loads or antennas at the ends of a number of leaky carriers 105; the communication signal source 100 is connected to the input end of the leaky unit 10 through the combiner/splitter 101, and the communication signals are transmitted through the leaky carrier 105 and indoor coverage is achieved Information exchange between the terminal 80 and the communication server, the positioning signal is obtained based on the position information exchanged between the position module 30 and the terminal 80, and the network performs indoor navigation positioning and communication based on the positioning signal and the communication signal. Specifically, the terminal 80 (as shown in FIG. 1B) or the positioning server (as shown in FIG. 1A) is used to calculate the position information exchanged between the position module 30 and the terminal 80, thereby realizing indoor communication and navigation and positioning.

The principle of the network communication interaction is: the communication signal is transmitted through the leaking unit 10 and covered indoors, and the terminal 80 can sense the communication signal and feedback information to the leaking unit 10, which is transmitted to the communication server through the communication signal source 100, thereby realizing the indoor terminal 80 and Communication server information exchange.

The principle of the network navigation positioning is that: in the first embodiment, the indoor communication integrated network includes a location module 30 integrated on the leaking unit 10, the location module 30 includes a location carrier 301, and the location carrier 301 It includes one or more of RFID tags, Bluetooth beacons, UWB base stations, WiFi base stations, and ZigBee beacons, where the terminal 80 can calculate the interaction information between it and the position carrier 301 to obtain positioning signals. In the second embodiment, the position module 30 further includes a positioning gateway 300, which is connected to the input terminal of the leaking unit 10 through the combiner/splitter 101, and sends connection requests and interactions to the positioning server, wherein the terminal 80 Perform information interaction with the location carrier 301. The leaking unit 10 or the location carrier 301 transmits the interactive information to the positioning gateway 300 after receiving the interactive information. The positioning gateway 300 passes it to the positioning server for calculation. The positioning signal obtained by the positioning server is used for navigation and positioning.

It should be noted that, based on the many types of location carriers 301, there are also multiple ways of information interaction between the terminal 80 and the location carrier 301, and this application roughly divides them into two categories.

For example, the location carrier 301 is the first category of UWB base stations. Based on the terminal 80 (UWB base station) sending time information and the UWB base station (terminal 80) response time information and/or signal reception angle and location data packets, the terminal 80 can be obtained. The flight time and/or the angle of arrival between the UWB base station and the UWB base station are determined to determine the flight distance and/or the angle of arrival to realize positioning, which can then be combined with the map to realize the itinerary navigation. More specifically, taking the terminal 80 to send information first, and the UWB response information as an example, TOF (Time of Flight), the time interval between the data packet sent by the terminal 80 and the response received is recorded as TTOT, and the UWB base station receives the data The time interval between the packet and the response is recorded as TTAT, then the one-way flight time of the data packet in the air TTOF=(TTOT-TTAT)/2; TW-TOF (two-way time-of-flight method)-SS ranging, the terminal 80 first sends UWB The base station sends out a data packet and records the packet sending time Ta1. After the UWB base station receives the data packet, it records the packet receiving time Tb1. After that, the UWB base station waits for the Treply time, and sends a data to the terminal 80 at the Tb2 (=Tb1+Treply) time After receiving the data packet, the terminal 80 writes down the time value Ta2, and then can calculate the flight time Tprop of the electromagnetic wave in the air. The flight time multiplied by the speed of light is the distance between the two terminals 80 and the UWB base station; TW-TOF (two-way flight) Time method)-DS ranging is to add another communication on the basis of SS ranging. The time of two communication can make up for the error introduced by the clock offset; the following is not a description of these existing UWB ranging principles.

For another example, in some specific implementations, the location carrier 301 may be a second category of one or more of RFID tags, Bluetooth beacons, WiFi base stations, or ZigBee beacons, and these location carriers 301 can publish their own location information ( It can also be combined with signal strength or signal angle) and received by the terminal 80. The terminal 80 can obtain the relative distance between the RFID tag or Bluetooth beacon or WiFi base station or ZigBee beacon and the terminal 80 based on the position information, that is, the positioning Signal, similarly, the positioning signal can also be obtained from the positioning server based on the position information. In other embodiments, the terminal 80 may also send location information. The location information sent by the terminal 80 is received by an RFID tag or a Bluetooth beacon or a WiFi base station or a ZigBee beacon. The signal is calculated based on the interactive information between the terminal 80 and the position carriers 301, thereby realizing navigation and positioning.

In a specific embodiment, in order to improve the positioning accuracy, the acquisition process of the positioning signal can also be obtained through auxiliary calculation of several sensing parameters. These sensing parameters may be environmental parameters or inertial parameters collected by the terminal 80 or/and the positioning server. Such as geomagnetism, infrared, etc.

The load or the antenna are all components connected to the output end of the leaky carrier 105.
