Description
Technical Field
The present invention relates to wireless communication technologies, and in particular, to a method and a system for implementing indoor coverage.
Background
The indoor covering technology is as follows: the indoor coverage system built in the building introduces the base station signal into the building, thereby realizing the network signal coverage technology.
Among them, the existing indoor coverage system is mostly realized by building a micro cellular base station. When the cellular base station mode is adopted, if the signal strength of the micro cellular base station is good and a call is initiated at any place inside a building, the signal of the micro cellular base station can be used as a first choice and cannot be easily switched to the signal of the macro cellular base station outside the building, and the cellular base station is considered to have a good indoor coverage effect; otherwise, traffic loss or handover call drop may result. At present, the realization mode for ensuring the coverage effect of the cellular base station is mostly to improve the antenna transmitting power and arrange more antenna points.
As can be seen from the above description, in order to ensure coverage effect in the existing indoor coverage technology, it is necessary to ensure that the signal strength of the femtocell is sufficiently stronger than that of the surrounding base stations, and this inevitably has certain drawbacks:
1. when the signal strength of the femtocell is enhanced by improving the transmitting power of the indoor antenna, the indoor antenna has limited transmitting power, and even if the indoor antenna reaches the maximum value, the advantages are difficult to be maintained under the condition that the coverage of the peripheral macro stations of the femtocell is good;
2. when the signal intensity of the micro-cellular base station is enhanced by adopting a mode of arranging multiple antenna points, due to the problems of attractiveness or construction difficulty and the like, the indoor coverage antenna points are arranged outside rooms such as a corridor and cannot enter a house, so that the signal attenuation is caused by the obstruction of a wall body in the inner space of a room of a building, and the high field intensity of the signal of the micro-cellular base station is difficult to ensure.
These drawbacks have the following consequences:
1. when the distance between macro base stations is relatively close or the signal intensity is relatively high outside a building where the micro-cellular base station is located, the macro base station outside the building can be optimized by the mobile phone in the building, so that when the user quantity in the building is large, telephone traffic is mostly absorbed by the macro base station outside the building, the peripheral area is busy, and the micro-cellular base station cannot absorb the telephone traffic;
2. when the mobile phone is positioned at the high-rise of a building and is close to a window, a long-distance base station signal with higher standing height possibly covers the high-rise window of the building and instantaneously keeps high field intensity, and the mobile phone can be occupied when the mobile phone starts to call; however, when a distant base station cannot maintain a continuously high field strength and needs to be switched, the mobile phone often cannot be switched due to the fact that the mobile phone has no adjacent cell relation with an indoor micro-cellular base station, and therefore call drop is caused.
Therefore, how to ensure that the indoor handset occupies the indoor femtocell signal for a long time without being interfered by the outdoor base station signal is a problem to be solved urgently at present.

The invention is described in further detail below with reference to the figures and the embodiments.
The method for realizing indoor coverage in the embodiment of the invention, as shown in fig. 1, comprises the following steps:
step 101: detecting the signal intensity of a femtocell, and judging whether the position of a terminal is located in a building covered by the femtocell when the signal intensity of the femtocell is greater than or equal to a preset threshold value in a preset time period;
here, the detecting the signal strength of the femtocell and determining that the signal strength of the femtocell is greater than or equal to a preset threshold in a preset time period specifically includes:
monitoring cell IDs corresponding to the detected N base stations with the optimal signal intensity in real time;
judging whether the cell ID corresponding to the N base stations with the optimal signal strength contains the cell ID corresponding to the micro-cellular base station in real time in the preset time period, and determining that the cell ID corresponding to the N base stations with the optimal signal strength contains the cell ID corresponding to the micro-cellular base station in real time in the preset time period, which indicates that the signal strength of the micro-cellular base station in the preset time period is determined to be greater than or equal to a preset threshold value.
Wherein, the value of N can set up as required, for example: set to 6, etc.
The preset time period can also be set according to needs, such as: 10 minutes, etc.
In practical application, the cell ID corresponding to which base station is the cell ID corresponding to the femtocell base station can be determined according to the naming rule of the cell IDs.
The determining whether the location of the terminal is located in a building covered by the femtocell base station specifically includes:
acquiring a closed area which is formed by surrounding of warps and wefts and corresponds to the occupied area of the building;
judging whether the position of the terminal is in the closed area or not, and if the position of the terminal is determined to be in the closed area, indicating that the position of the terminal is in the building; and if the terminal is determined to be located in the closed area, indicating that the terminal is located in a position not located in the building.
In practical application, the closed area surrounded by the latitude and longitude lines corresponding to the occupation area of the building can be determined in the following manner:
acquiring the latitudes of the northest end and the soutest end corresponding to the occupation area of the building, and acquiring the longitudes of the easst side and the westest side corresponding to the occupation area of the building; and enclosing the obtained latitude at the northest end, the latitude at the soutest end, the longitude at the easst side and the longitude at the westest side into an enclosed area, thus obtaining the enclosed area which is enclosed by the latitude and the longitude and the latitude and corresponds to the occupied area of the building.
Here, the latitudes of the north and south ends and the longitudes of the east and west ends corresponding to the occupied area of the building can be acquired through functions such as positioning of the terminal and a satellite map.
Before determining whether the terminal is located in a building covered by the femtocell base station, the method may further include:
inquiring the name of the building from an OMS according to the cell ID corresponding to the micro-cellular base station;
correspondingly, according to the name of the building, a closed area which is corresponding to the occupied area of the building and is formed by surrounding of the longitude and the latitude lines is obtained.
Here, the querying, according to the cell ID corresponding to the femtocell, the name of the building from the OMS specifically includes:
sending a cell ID corresponding to the micro-cell base station to the OMS;
and after receiving the cell ID corresponding to the micro-cellular base station, the OMS inquires a base station information table of the OMS, and obtains and returns the name of the building.
According to the name of the building, the satellite map of the current position of the terminal acquired through the network is utilized to inquire and obtain the latitudes of the north end and the south end corresponding to the occupied area of the building, and the longitudes of the east side and the west side corresponding to the occupied area of the building are acquired.
Step 102: and when the position of the terminal is determined to be in a building covered by the micro-cellular base station, taking the micro-cellular base station as a base station interacting with the terminal.
Here, before the femtocell base station is used as a base station interacting with the terminal, the method may further include:
filtering and weakening all frequency points except the frequency point corresponding to the microcellular base station step by step; all the frequency points refer to the frequency points corresponding to all the other base stations except the femtocell base station in all the base stations which detect the signals, so that the terminal in the building can be further ensured to occupy the signals of the femtocell base station for a long time without being interfered by the signals of other base stations.
The specific processing procedure of filtering and gradually weakening all frequency points except the frequency point corresponding to the femtocell base station is not the content concerned by the present invention. Of course, the specific processing procedure of filtering and gradually weakening all frequency points except the frequency point corresponding to the femtocell base station may adopt the prior art.
The taking the femtocell as a base station interacting with the terminal specifically includes:
and taking the micro-cellular base station as a base station interacting with the terminal through a cell reselection process or a cell switching process.
Specifically, when the terminal is in an idle state, the femtocell base station may be used as a base station interacting with the terminal through a cell reselection process; when the terminal is in a call use state, due to the attenuation of signals of other base stations, the femtocell base station can be used as a base station interacting with the terminal through a cell switching process.
After the femtocell base station is used as a base station interacting with the terminal, the method may further include:
detecting whether the position of the terminal is located in the building in real time, and removing the filtering and weakening of all frequency points except the frequency point corresponding to the microcellular base station after determining that the position of the terminal is not located in the building; thus, the terminal can receive all the received base station signals again; at this time, the terminal may be restored to a normal state through a cell reselection or a cell handover procedure.
When the terminal is far away from the building, namely the signal intensity of the femtocell base station cannot be detected, the functions of positioning, satellite maps and the like of the terminal can be closed; but still monitoring the cell IDs corresponding to all base stations capable of receiving the base station signals in real time, and continuing to execute the steps 101-102 until a new cell ID corresponding to the femtocell base station appears.
According to the method for realizing indoor coverage provided by the embodiment of the invention, when the position of the terminal is determined to be in a building covered by the micro-cellular base station, the micro-cellular base station is used as a base station interacting with the terminal, and the access and signal occupation of the terminal are controlled from the terminal side, so that the terminal in the building can occupy the signal of the micro-cellular base station for a long time without being interfered by the signals of other base stations.
In addition, the signal strength of the femtocell base station is detected, when the signal strength of the femtocell base station is determined to be greater than or equal to a preset threshold value within a preset time period, whether the position of the terminal is located in a building covered by the femtocell base station is judged, and when the position of the terminal is determined to be located in the building, the femtocell base station is used as a base station interacting with the terminal, so that the signal of the femtocell base station can be ensured to have higher strength, and therefore, the terminal located in the building can be further ensured to occupy the signal of the femtocell base station for a long time without being interfered by signals of other base stations.
In addition, all frequency points except the frequency point corresponding to the micro-cellular base station are filtered and weakened gradually, so that the terminal in the building can be further ensured to occupy the signal of the micro-cellular base station for a long time without being interfered by signals of other base stations.
An implementation method of indoor coverage in an application embodiment of the present invention, as shown in fig. 2, includes the following steps:
step 200: monitoring cell IDs corresponding to the detected N base stations with the optimal signal intensity in real time;
here, the value of N is 6.
Step 201: when cell IDs corresponding to the femtocell base stations appear in cell IDs corresponding to N monitored base stations with optimal signal strength, judging whether the cell IDs corresponding to the N base stations with optimal signal strength contain the cell IDs corresponding to the femtocell base stations in real time in a preset time period, if so, executing step 202, otherwise, executing step 209;
here, it may be determined which base station corresponds to the cell ID that is the cell ID corresponding to the femtocell base station according to a naming rule of the cell ID.
The purpose of judging whether the cell IDs corresponding to the N base stations with the optimal signal strength include the cell ID corresponding to the femtocell base station in real time within a preset time period is as follows: and judging whether the signal of the micro-cellular base station is stable, if not, the micro-cellular base station cannot be adopted to interact with a terminal, otherwise, a higher call drop rate is caused.
Step 202: inquiring the name of a building covered by the micro-cellular base station from an OMS according to the cell ID corresponding to the micro-cellular base station;
specifically, a cell ID corresponding to the femtocell base station is sent to the OMS through a network;
and after receiving the cell ID corresponding to the micro-cellular base station, the OMS queries a base station information table of the OMS to obtain the name of the building, and returns the name of the building through a network.
Step 203: according to the obtained name of the building, obtaining the latitudes of the northmost end and the southwest end corresponding to the occupation area of the building, and obtaining the longitudes of the easst side and the westest side corresponding to the occupation area of the building;
here, the latitude of the north-most end and the south-most end and the longitude of the east-most side and the west-most side corresponding to the floor area of the building may be acquired by using functions such as positioning of the terminal and a satellite map.
Step 204: enclosing the obtained latitude of the north end, the latitude of the south end, the longitude of the east side and the longitude of the west side into an enclosed area to obtain the enclosed area which is enclosed by the latitude and the longitude and is corresponding to the occupied area of the building;
step 205: judging whether the position of the terminal is in the closed area, if so, executing a step 206, otherwise, executing a step 209;
step 206: filtering and gradually weakening all frequency points except the frequency point corresponding to the microcellular base station, and then executing step 207;
here, the all frequency points refer to frequency points corresponding to all base stations except the femtocell base station among all base stations which detect signals.
Step 207: using the femtocell base station as a base station interacting with the terminal through a cell reselection process or a cell handover process, and then executing step 208;
specifically, when the terminal is in an idle state, the femtocell base station may be used as a base station interacting with the terminal through a cell reselection process; when the terminal is in a call use state, due to the attenuation of signals of other base stations, the femtocell base station can be used as a base station interacting with the terminal through a cell switching process.
Step 208: continuously monitoring cell IDs corresponding to the detected N base stations with the optimal signal strength in real time, removing the filtering and weakening of all frequency points except the frequency point corresponding to the micro-cell base station after the cell IDs corresponding to the micro-cell base station do not appear in the cell IDs corresponding to the N base stations with the optimal signal strength any more, and then executing step 209;
here, after removing the filtering and weakening of all frequency points except the frequency point corresponding to the femtocell base station, the terminal may receive all base station signals that can be received again; at this time, the terminal may be restored to a normal state through a cell reselection or a cell handover procedure.
Step 209: the current processing procedure is ended.
By applying the method of the embodiment, when the terminal is far away from the building, that is, the signal strength of the femtocell base station cannot be detected, the functions of positioning, satellite map and the like of the terminal can be closed; but still monitoring the cell IDs corresponding to all base stations capable of receiving the base station signals in real time, and executing the steps 201 to 209 again until a new cell ID corresponding to the femtocell base station appears.

Of course, the specific processing procedure of filtering and gradually weakening all frequency points except the frequency point corresponding to the femtocell base station may adopt the prior art.
The first determining module 31 is further configured to detect whether the location of the terminal is located in the building in real time after the femtocell base station is used as a base station interacting with the terminal, and trigger the filtering module after determining that the location of the terminal is not located in the building;
the filtering module is further configured to remove filtering and weakening of all frequency points except the frequency point corresponding to the femtocell base station after receiving the trigger of the first determining module 31; thus, the terminal can receive all the received base station signals again; at this time, the terminal may be restored to a normal state through a cell reselection or a cell handover procedure.
When the terminal is far away from the building, namely the signal intensity of the femtocell base station cannot be detected, the functions of positioning, satellite maps and the like of the terminal can be closed; however, the second determining module 33 still monitors the cell IDs corresponding to all base stations capable of receiving the base station signals in real time, and triggers the first determining module 31 to continuously determine that the location of the terminal is in the building covered by the femtocell base station until a new cell ID corresponding to the femtocell base station appears, and triggers the operation of the communication module 32 after determining that the location of the terminal is in the building covered by the femtocell base station, so that each module executes the corresponding operation.
In practical applications, the first determining module 31, the second determining module 33 and the filtering module may be implemented by a Central Processing Unit (CPU), a Digital Signal Processor (DSP), or a Programmable logic Array (FPGA) in an indoor coverage implementing apparatus; the acquisition module can be realized by a transceiver in an indoor coverage realization device; the communication module 32 may include: transceivers, modems, and the like.
In the device for implementing indoor coverage provided in the embodiment of the present invention, when the first determining module 31 determines that the location of the terminal is in the building covered by the femtocell base station, the femtocell base station is used as a base station interacting with the terminal, and the access and signal occupation of the terminal are controlled from the terminal side, so that the terminal in the building can occupy the signal of the femtocell base station for a long time without being interfered by signals of other base stations.
In addition, when the second determining module 33 detects the signal strength of the femtocell base station and determines that the signal strength of the femtocell base station is greater than or equal to a preset threshold value within a preset time period, the first determining module 31 then determines whether the position of the terminal is located in the building covered by the femtocell base station, and when the position of the terminal is determined to be located in the building covered by the femtocell base station, the communication module 32 uses the femtocell base station as a base station interacting with the terminal, so that the signal of the femtocell base station can be ensured to have higher strength, and thus, the terminal located in the building can be further ensured to occupy the signal of the femtocell base station for a long time without being interfered by signals of other base stations.
In addition, the filtering module filters and weakens all frequency points except the frequency point corresponding to the micro-cellular base station step by step, so that the terminal in the building can be further ensured to occupy the signal of the micro-cellular base station for a long time without being interfered by signals of other base stations.
