Problems solved by technology

[0004] Using the UE measurement report instead of manual on-site measurement brings great convenience for locating wireless network problems. However, the wireless measurement report only records the cell where the problem occurred, and does not record the specific location where the problem occurred.

Embodiment Construction

[0100] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0101] The method for locating an indoor wireless network coverage problem area according to the present invention is used to locate coverage blind areas and problem devices of an indoor distributed system network in a building. The building has five floors, each of which has the same structure. There is a WCDMA network built in the area. The WCDMA network inside the building is covered by the indoor distributed system, and the WCDMA network outside the building is covered by the outdoor macro base station. The indoor distributed system and the outdoor macro base station belong to different communities.

[0102] It should be noted that the technical solutions of the present invention are not limited to WCDMA networks, but can also be applied to a combination of one or more wireless wide area networks.

[0103] Such as figure 1 As shown, a method for p...

Abstract

The invention discloses a method of positioning problem regions covered with an indoor wireless network. The method comprises the following steps: constructing an indoor and outdoor combined three-dimensional spatial structural model of a target scene, wherein the scene comprises an indoor three-dimensional scene of a target building and an outdoor three-dimensional scene around the target building; recording and storing information of wireless access equipment which can be received by the target scene; establishing a wireless fingerprint database of the target building; collecting a wireless measurement report MR reported by common user equipment UE on the network side of the wireless access equipment, analyzing the MR, and initially judging the position of the common UE with problems; pretreating fingerprint identification data; and judging specific position information of the common UE through fingerprint identification. The method disclosed by the invention can precisely position the problem regions covered with the indoor network to position network apparatuses with faults by means of the measurement report of a user and an indoor signal fingerprint database in the building without on-site measuring by network maintenance personnel.

Description

technical field [0001] The invention relates to a method for locating an indoor wireless network coverage problem area, which belongs to the field of indoor wireless network maintenance in the field of mobile communication. Background technique [0002] In the 2G era dominated by voice communication, indoor coverage can be achieved by relying on outdoor macro base stations. With the development of wireless communication technology and the increase of indoor data services, indoor wireless signals have become more and more important. Indoor distributed systems have become one of the most important forms to solve indoor wireless network coverage. Indoor wireless communication networks are becoming more and more Complex, 2G / 3G / LTE / WiFi and other network standards coexist, it is becoming more and more difficult to upgrade and maintain the existing complex indoor wireless network, and quickly locate indoor coverage blind spots and faulty devices. Traditional indoor wireless netwo...
