All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a RSRP weak area point location fault identification method according to an embodiment of the present invention, and fig. 4 is an antenna distribution system diagram according to an embodiment of the present invention, as shown in fig. 1, the method includes:
step S01, acquiring weak sampling points of which all reference signal receiving powers in the indoor area meet weak coverage;
in the process of building an indoor wireless communication network, due to the complexity of an indoor environment, the building of the network is also more complex than that of an outdoor environment, and a failure of any one device, such as an antenna or a coupler, may cause weak coverage of a cell. The Reference Signal Receiving Power (RSRP) of each location can be obtained by performing Signal detection on each location in the indoor area. And then judging whether the received RSRP meets weak coverage according to preset conditions. The preset condition may be a preset power threshold, and once the received RSRP is smaller than the power threshold, it may be determined that the position of the test terminal that sends the RSRP is a weak sampling point that satisfies weak coverage. All weak sampling points in the indoor area can be obtained through detection of all places in the indoor area.
And step S02, obtaining the problem antenna corresponding to each weak sampling point according to the weak sampling points.
The indoor wireless communication network is realized by the antennas distributed at each position indoors, the antenna corresponding to the position of each weak sampling point can be obtained through the distribution condition of the antennas at the periphery of each weak sampling point, and the antenna is judged to be a problem antenna.
And step S03, determining problem devices according to the pre-stored antenna distribution system diagram and all problem antennas, wherein the antennas connected with the problem devices are all the problem antennas.
And checking a pre-stored antenna distribution system diagram, wherein the antenna distribution system diagram comprises distribution conditions of all indoor antennas and devices connected with all the antennas, such as a coupler capable of being connected with two paths of antennas, a power divider capable of being connected with four paths of antennas and the like. And marking the obtained problem antenna on the antenna distribution system diagram, and if the antennas connected with the device are marked as the problem antenna, judging that the device is the problem device, namely the fault of the connected problem antenna is probably caused by the problem device but not the problem antenna. Of course, there is also a connection relationship between devices, and the devices on the lower layer connected to the problem device are also the problem devices.
As shown in fig. 4, a01-a15 is an antenna, B01-B09 is a device, and if a04-a09, a13, and a14 are problem antennas, since a04-a06 connected to device B02 and a07-a09 connected to device B03 are both problem device antennas, devices B02 and B03 are determined to be problem devices; whereas only a13 and a14 of the antennas connected to device B05 were problem antennas, then B05 was not a problem device; in addition, since both the devices B02 and B03 connected to the device B06 were problem devices, the device B06 was also determined to be a problem device.
