Embodiment 1

[0038] figure 1 It is a system architecture diagram of a typical indoor coverage system. Such as figure 1 As shown, it includes a base station, an indoor distribution system, and a mobile station (Mobile Station, MS), where the base station includes, for example, a radio network controller (Radio Network Controller, RNC) / base station controller (Base Station Controller, BSC), and baseband processing Unit (Building Baseband Unit, BBU) and remote radio unit (Remote Radio Unit, RRU), or base transceiver station (Base Transceiver Station, BTS) instead of baseband processing unit (BBU) and remote radio unit, MS such as mobile phone . During the downlink communication, the base station sends downlink signals to the indoor distribution system, and the indoor distribution system sends the downlink signals to the MS; during the uplink communication, the MS sends uplink signals to the indoor distribution system, and the indoor distribution system sends the uplink signals to the MS. t...

Embodiment 2

[0057] On the basis of Embodiment 1, in this embodiment, the step of sending the pseudo-carrier patrol to the remote units within the preset range specifically includes:

[0058] According to the patrol routing table, the remote unit of the current patrol is determined, and the pseudo carrier is sent to the remote unit of the current patrol.

[0059] In this embodiment, taking the indoor distribution system further including an expansion unit as an example, the steps of obtaining the patrol routing table are described. Wherein, the expansion unit is arranged between the main unit and the remote unit, forming a structure in which the main unit is connected to one or more expansion units, and each expansion unit is connected to one or more remote units.

[0060] The steps for obtaining the patrol routing table include, for example:

[0061] Obtain the optical fiber interface of the main unit, and establish a first-level interface table including the optical fiber interface;

...

Embodiment 3

[0073] On the basis of any of the above embodiments, the sending the pseudo-carrier patrol to the remote units within the preset range specifically includes:

[0074] Sending the pseudo-carrier to the remote units within the preset range in rounds in the form of digital signals and / or analog signals;

[0075] Correspondingly, the polling sending is realized by controlling the logic switch array and / or controlling the single-pole multi-throw switch.

[0076] Specifically, the indoor positioning system used to implement the indoor positioning method in any of the foregoing embodiments may be a digital system, an analog system, or a system combining digital and analog. In the following, the signal processing methods in the indoor positioning system will be described in detail for these three situations respectively.

[0077] Scenario 1: The indoor positioning system is a fully digital distribution system

[0078] Figure 5 It is a system architecture diagram of the indoor posi...

Abstract

The invention provides an indoor locating method, a data acquisition method and a data acquisition system. The indoor locating method comprises the following steps: obtaining a pseudo carrier; transmitting the pseudo carrier to a remote unit in a predetermined range in a polling manner and radiating the pseudo carrier in the room through the remote unit; obtaining response information fed back by a mobile station in the predetermined range, and locating the mobile station according to the condition that whether the pseudo carrier information is carried in the response information. According to the indoor locating method, the data acquisition method and the data acquisition system provided by the invention, the effective automatic indoor location is realized.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an indoor positioning method, a data collection method and a system. Background technique [0002] With the development of wireless communication technology, traffic density and coverage requirements continue to rise. Due to the excessive user density and the shielding effect of buildings on mobile phone signals, the traditional indoor distribution system is increasingly unable to accommodate the large-capacity requirements of multi-band, multi-mode, and multi-operator. [0003] Multi-frequency and multi-mode digital optical fiber distribution system, as the evolution form of the new generation of indoor coverage system, has become one of the mainstream indoor coverage solutions. Compared with the traditional indoor distribution system, it has unique functions, such as: replace the same Axial cables, reduce signal attenuation, improve efficiency, and digitalizatio...
