Description
Technical Field
The present invention relates to the field of mobile communications, and in particular, to a method and an apparatus for detecting reverse antenna connection.
Background
In a mobile communication network, a fourth generation mobile communication technology (4G) network inherits a cellular structure of a third generation mobile communication technology (3G) network. In one example, the networking method adopted by the 4G network is, for example: three cells are deployed at one physical site. Referring to fig. 1, a 3G cell and a 4G cell are typically deployed simultaneously on the same physical site. During network planning, the directions of the 3G sector and the 4G sector are generally kept consistent to ensure that each 3G cell and the corresponding 4G cell cover the same geographical range, and therefore, the coverage areas of the 3G cell and the 4G cell are the same, as shown in fig. 1. At this time, referring to fig. 1, in the 4G base station, the connection order of the Radio Remote Unit (RRU) and the baseband processing unit (BBU) is as follows: the RRU connected with the antenna of the 4G cell 1 can be connected to a first port of the BBU, the RRU connected with the antenna of the 4G cell 2 can be connected to a second port of the BBU, the RRU connected with the antenna of the 4G cell 3 can be connected to a third port of the BBU. Since the 4G network belongs to a newly-built network, in the process of engineering construction or daily equipment maintenance, a problem of reverse antenna connection of the 4G cell may occur, that is, the RRU should be connected to the first port of the BBU, and in the actual connection, the RRU should be connected to the second port of the BBU, for example, the RRU connected to the antenna of the 4G cell 1 should be connected to the first port of the BBU, and in the actual connection, the RRU should be connected to the second port of the BBU in a wrong way, and similarly, the RRU connected to the antenna of the 4G cell 2 is connected to the first port of the BBU in a wrong way. Thus, when a certain 4G cell antenna is switched back when actually deployed, the coverage area of the 4G cell may be different from the pre-planned coverage area.
The traditional cell antenna reverse connection diagnosis mode is as follows: manually carrying out road test to judge whether the cell antenna is reversely connected; or, when a tester goes to the sky of the base station, the testing terminal is adopted to identify signals transmitted by each cell antenna so as to judge whether the cell antenna is reversely connected, and the two diagnosis modes have the problems of long time consumption, high cost, unsuitability for large-scale diagnosis and the like. In the prior art, a diagnosis method based on data such as a 4G network neighboring cell handover relationship and Measurement Reports (MRs) also exists, but a large amount of data needs to be iteratively processed to judge whether a cell antenna is reversely connected, so that the operation complexity is high, the processing data amount is huge, and the diagnosis accuracy is poor in a region with a high reverse connection rate.

In the description of the present application, the meaning of "a plurality" means two or more unless otherwise specified.
The method for detecting the reverse antenna connection provided by the embodiment of the application can be applied to a system for detecting the reverse antenna connection, as shown in fig. 1. The system comprises a base station, a network management platform and an antenna reverse detection device.
The base station related to the embodiments of the present application may also be referred to as a physical station. Each station may be deployed with one or more first network cells and one or more second network cells simultaneously.
And the antenna reverse connection detection device is used for determining the matching first network cell of the second network cell according to the interoperation records of the second network cell and at least one first network cell, and then determining whether the antenna of the second network cell is reverse connected or not according to the matching first network cell of the pre-configured first network cell and the second network cell of the second network cell.

The base station and the network management platform may be independent hardware devices, or may be based on a virtualization function of a virtualization technology, and the device forms of the base station and the network management platform in the embodiment of the present application are not limited.
As a possible implementation manner, the second network cell mentioned in this embodiment of the present application refers to a 4G cell, and the first network cell mentioned in this embodiment is a 3G cell. The 4G cell is a cell served by adopting a 4G standard, and the 3G cell is a cell served by adopting a 3G standard. The first network cell does not have the phenomenon of reverse antenna connection, and the actual distribution condition of the first network cell is used as the calibration basis of the actual distribution condition of the second network cell. The distribution condition of the cells can be determined by the geographical position, the coverage area and the like of the cells. The description is not repeated herein.
When the antenna connection of the second network cell is normal, that is, when the network is actually deployed, the RRU is connected to the BBU port set in the pre-planning, that is, the RRU is connected to the correct port in the BBU, for example, when the network is pre-planned, the RRU is set as: the RRU connected with the first cell antenna is connected to a first port of the BBU, and when the network is actually deployed, the RRU connected with the first cell antenna is connected to the first port of the BBU; when the network is planned in advance, the following settings are set: the RRU connected to the second cell antenna should be connected to the second port of the BBU, and when the network is actually deployed, the RRU connected to the second cell antenna is connected to the second port of the BBU.
When the second network cell antenna is inversely connected, it means that when the network is actually deployed, the RRU is not connected to the BBU port set in the pre-planning, that is, the RRU is connected to the wrong interface in the BBU, for example, when the network is pre-planned, the configuration is: the RRU connected with the first cell antenna is connected to a first port of the BBU, and when the network is actually deployed, the RRU connected with the first cell antenna is connected to a second port of the BBU in a staggered manner; when the network is planned in advance, the following settings are set: the RRU connected to the second cell antenna should be connected to the second port of the BBU, and when the network is actually deployed, the RRU connected to the second cell antenna is connected to the first port of the BBU.
When the network is planned in advance, the 3G cell corresponding to the 4G cell, that is, the 3G cell whose coverage area with the 4G cell is overlapped more than the first threshold value, may be referred to as a pre-configured 3G cell of the 4G cell. For example, referring to fig. 2, when a network is preplanned, a 4G cell 1 is preconfigured to correspond to a 3G cell 1, the 3G cell may be referred to as a preconfigured 3G cell of the 4G cell 1, and a 4G cell 2 is preconfigured to correspond to a 3G cell 2, so that the 3G cell 2 is a preconfigured 3G cell of the 4G cell 2.
In the embodiment of the present application, when a network is preplanned, a planning distribution condition of a 4G cell and a preconfigured cell corresponding to the 4G cell includes a corresponding relationship between the 4G cell and a preconfigured 3G cell corresponding to the 4G cell. When the network is planned in advance, the overlapping degree of the coverage areas of the 4G cell and the pre-configured 3G cell corresponding to the 4G cell is larger than a first threshold value.
Generally, when the antenna connection of a certain 4G cell is normal, i.e. the antennas are not connected in reverse, the probability of coincidence of the coverage area of the 4G cell with the corresponding preconfigured 3G cell is larger than a first threshold. Coverage area referring to fig. 2, fig. 2 shows the actual distribution of 4G cells in the case that the 4G cell antennas are connected normally (i.e. the antennas are not reversed). Here, the first network cell is a 3G cell and the second network cell is a 4G cell. Assume that the first threshold is 80%. The coincidence probability of the coverage areas of the 4G cell 1 and the 3G cell 1 is 92% (greater than the first threshold value 80%), which indicates that the antenna connection of the 4G cell is normal, and similarly, the coincidence probability of the coverage area of the 4G cell 2 and the coverage area of the preconfigured 3G cell (i.e. the 3G cell 2) is 90% (greater than 80%), which indicates that the antenna connection of the 4G cell 2 is normal, and the coincidence probability of the coverage area of the 4G cell 3 and the coverage area of the preconfigured 3G cell (i.e. the 3G cell 3) is 91% (greater than 80%), which indicates that the antenna connection of the 4G cell 3 is normal.
It will be appreciated that when the antennas of a 4G cell are reversed, it may result in a probability of coincidence of the coverage area of the 4G cell with the coverage area of the corresponding pre-configured 3G cell being less than the second threshold. Referring to fig. 3, fig. 3 shows the actual distribution of 4G cells in the case of reverse antenna connection of 4G cells. The 4G cell 1 and the 3G cell 2 coincide in coverage area, and the 4G cell 2 and the 3G cell 1 coincide in coverage area. That is, the coverage areas of the preconfigured 3G cells (i.e. 3G cell 1) of 4G cell 1 and 4G cell 1 are different, i.e. the probability of coincidence of the coverage areas of the preconfigured 3G cells (i.e. 3G cell 1) of 4G cell 1 and 4G cell 1 is smaller than the second threshold, indicating that the antenna of 4G cell 1 is connected in reverse, and similarly, the coverage areas of the preconfigured 3G cells (i.e. 3G cell 2) corresponding to 4G cell 2 and 4G cell 2 are different, indicating that the antenna of 4G cell 2 is connected in reverse.
The first threshold and the second threshold may be flexibly set according to an application scenario, which is not limited in the embodiment of the present application.
In a mobile communication network, terminals need to interoperate between different network systems due to network coverage, service, load balancing, and the like. For example, the terminal falls back from the 4G network cell to the 3G network cell in a handover or redirection manner due to network coverage, or falls back from the 4G network cell to the 3G network cell in a Circuit Switched Fallback (CSFB) manner due to voice service.
The dropping of the terminal from the 4G network cell to the 3G network cell in a handover or redirection manner due to network coverage is: the terminal is in a region with weak 4G network coverage, for example, when the terminal is in an indoor environment, because a 4G network cell signal is weak, a service requirement of the terminal cannot be met, the terminal may obtain an instruction sent by the 4G network device to instruct the terminal to leave the 4G network through switching or redirection and the like, and access the 3G network.
For voice service reasons, the falling back of the terminal from the 4G network cell to the 3G network cell in the circuit switched fallback mode means: in a 4G network that does not provide a VoLTE (voice over LTE) function, since the 4G network of this type does not have a capability of carrying a voice service, when a terminal initiates a voice service, the terminal needs to fall back from the 4G network to a 3G network, and the 3G network carries the voice service.
When a terminal performs interoperation between different network types, for example, when the terminal is switched from a certain second network cell to a first network cell, the signal strength of the first network cell having a higher overlap ratio with the coverage area of the second network cell is usually stronger. Correspondingly, after the terminal is separated from the second network cell, the probability of accessing the first network cell with higher coverage area coincidence degree is higher. Referring to fig. 2, if the terminal performs an interworking, departing from the 4G cell 1, the terminal may be attached to the 3G cell 1, the 3G cell 2, or the 3G cell 3. Wherein, because the overlapping degree of the coverage areas of the 3G cell 1 and the 4G cell 1 is higher, the probability that the terminal accesses to the 3G cell 1 is higher. Referring to fig. 3, if the terminal performs an interworking, departing from the 4G cell 1, the terminal may be attached to the 3G cell 1, the 3G cell 2, or the 3G cell 3. Wherein, because the overlapping degree of the coverage areas of the 3G cell 2 and the 4G cell 1 is higher, the probability that the terminal accesses to the 3G cell 2 is higher.
In the embodiment of the present application, the first network cell antenna does not have the reverse connection phenomenon, and whether the antenna of the second network cell is reversely connected or not can be checked by using the actual matching condition of the first network cell. Specifically, based on the interoperation records of the second network cell and at least one first network cell, it is determined that the second network cell matches the first network cell, and then based on the preconfigured first network cell of the second network cell and the matching first network cell of the second network cell, it is determined whether the antenna of the second network cell is reversely connected.
An embodiment of the present application provides an antenna reverse detection method, as shown in fig. 4, the method may include steps 401 to 403:
The interoperation record is a record of the terminal separating from the second network cell and accessing the first network cell. Each interoperation of the terminal corresponds to one interoperation record. The interworking record of the first network cell and the second network cell may be an interworking record between 3G and 4G networks. For example, the terminal falls back from the 4G network to the recording of the 3G network in a handover or redirection manner due to network coverage, or falls back from the 4G network to the recording of the 3G network in a circuit switched fall back manner due to voice service. The interoperation record includes a user identification code, a time (specifically, millisecond level) when the interoperation occurs, a second network cell identifier used by the terminal before the interoperation, and a first network cell identifier used by the terminal after the interoperation, which are specifically shown in table 1.
TABLE 1
Referring to table 1 above, the record of interoperation between the second network cell of cell identification 43768113 and the first network cell of cell identification 7621367 includes: the subscriber identity 130XXXX1234, the time of interoperation between the second network cell and the first network cell 2018/1/11:00:02.234, the identity of the second network cell 43768113, and the identity of the first network cell 7621367.
The subscriber identity may be an International Mobile Subscriber Identity (IMSI) of the subscriber, an International Mobile Equipment Identity (IMEI) of the terminal, a mobile phone number of the subscriber, or other information that can uniquely identify the subscriber.
For the current second network cell, obtaining the interoperation record of the current second network cell and the at least one first network cell means obtaining the interoperation record between the current second network cell and each first network cell in the at least one first network cell. For example, the at least one first network cell may be a first network cell that is adjacent to the current second network cell. Assuming that the first network cells adjacent to the current second network cell are cell 1, cell 2, and cell 3, when determining whether the antenna of the current second network cell is connected reversely, the interoperation record between the current second network cell and cell 1, the interoperation record between the current second network cell and cell 2, and the interoperation record between the current second network cell and cell 3 need to be obtained.
And the matched first network cell is the first network cell with the maximum access probability after the terminal is separated from the second network cell. In the embodiment of the present application, the first network cell with the highest access probability is the first network cell with the largest matching value. The matching value is determined by the number of interoperation records between the second network cell and each of the first network cells.
Referring to fig. 5, step 402 may be embodied as the following steps:
(optional) step 4021, acquiring a timing advance corresponding to the current interoperation record.
As described above, each interoperation record corresponds to one second network cell and one first network cell, wherein for the current interoperation record, the timing advance corresponding to the current interoperation record is used to indicate whether the terminal is located in the coverage of the first network cell corresponding to the current interoperation record.
In a 4G mobile communication system, in order to avoid uplink interference between different terminals within the coverage of a base station, different timing advances are set for terminals with different distances from the base station, so as to ensure that the time when signals of different terminals using the same communication subframe but different frequency domain resources reach the base station is aligned. Therefore, based on the timing advance of the terminal, the separation distance between the terminal and the base station can be determined, and the specific calculation formula is as follows:
dTA＝TA*c (1)
wherein d isTAThe distance between the terminal and the base station is shown, where TA shows the timing advance of the terminal and c shows the speed of light, as shown in fig. 2.
It can be understood that the distance d between the terminal and the base station is calculatedTAThen, can be according to dTAAnd the size relationship of the coverage of the first network cell (which may be represented by a preset coverage distance, for example), to determine whether the terminal is within the coverage of the first network cell.
Specifically, referring to fig. 6, the coverage area of the first network cell may be calculated according to the following formula:
wherein B represents the set of base stations in the target area, n represents the number of base stations in the set of base stations B, dcIndicating a predetermined coverage distance, d, of the first network celli,jRepresents the separation distance between base station i and base station jThe base station j is the base station closest to the base station i in the base station set B, α represents a scaling factor of the center of the first network cell, and is used for adjusting the logical position (or logical range) of the edge of the first network cell, and 0 < α < 1. Here, the smaller α, the larger the logical range of the first network cell edge, and the smaller the coverage of the first network cell.
As a possible implementation manner, a wireless network management platform in the 4G mobile communication system can record Timing Advance (TA) of each terminal at different times, and the specific recorded information includes a user identifier and TA values at different times, and terminals with different user identifiers may have different TA values. When information is extracted from the wireless network management platform, the specifically extracted information includes a user identification code, time (specifically to millisecond level) and a TA value corresponding to each time.
As a possible implementation manner, the timing advance corresponding to the current interoperation record is obtained, and the specific implementation manner is as follows: and acquiring a TA value of the terminal at the time which is closest to the current interoperation record occurrence time and does not exceed a preset time threshold from the wireless network management platform according to the user identification code in the current interoperation record and the current interoperation occurrence time, wherein the TA value is used as the timing advance corresponding to the current interoperation record. The TA value satisfies the following relationship:

For example, the subscriber identity of the terminal 1 executing the current interoperation record is 150xxxx1111, and the wireless network management platformRespectively storing TA corresponding to 3 terminals (respectively corresponding to 3 user identification codes), wherein a terminal 1 corresponds to a plurality of TAs, a terminal 2 corresponds to a plurality of TAs, a terminal 3 corresponds to a plurality of TAs, the TA corresponding to the 3 terminals forms a TA record set B, and correspondingly, when the TA corresponding to the current interoperation record of the terminal 1 needs to be acquired, the UID (user identifier) is used for identifying the TA corresponding to the current interoperation record of the terminal 1A＝UIDBThis indicates that the TA of terminal 1 is selected from the TA record set B. timeB,xTime, representing the time of the xth timing advance in the set of timing advance records BB,yTime, representing the time of the y-th timing advance in the set of timing advance records BAIndicates the time of the current interoperation record A, TthRepresenting a time threshold.
Referring to fig. 7, the user id of the terminal 1 performing the current interworking is 150xxxx1111, whose timing advance at the time x-3 is TA1, timing advance at the time x-2 is TA2, timing advance at the time x-1 is TA3, timing advance at the time x is TA4, timing advance at the time x +1 is TA5, and timing advance at the time x +2 is TA 6. With the current interoperation time as a starting point, fall into a time threshold TthThere are two timing advances in the range, which are: the timing advance corresponding to the time x-1 is TA3, and the timing advance corresponding to the time x is TA 4. And the time interval between the time x and the current interoperation time is smaller than the time interval between the time x-1 and the current interoperation time, and at this time, the timing advance TA4 corresponding to the time x is taken as the timing advance recorded by the current interoperation.
Illustratively, the user identifier of the terminal is 130XXXX1234, and the timing advance corresponding to the current interoperation record of the terminal obtained by the above method is shown in table 2 below:
TABLE 2
(optional) step 4022, if the terminal is located outside the coverage of the first network cell corresponding to the current interoperation record, deleting the current interoperation record.
Referring to fig. 8, fig. 8 shows a schematic location diagram of the terminal outside the coverage of the first network cell. If the terminal is located outside the coverage area of the first network cell, for example, the edge area farther from the center point of the first network cell or the overlapping coverage area of the first network cells, the terminal can receive signals of the surrounding first network cells, and the signal strength is equivalent. Therefore, when the terminal is separated from the second network cell and accesses the first network cell, a plurality of selectable first network cells are available, and the probability of falling back to the first network cell in the same sector as the second network cell is greatly reduced, for example, in fig. 8, because the coverage area of the terminal 3G cell is out, after the terminal is separated from the 4G cell 1, the probability of accessing the 3G cell 1 in the same sector is reduced, and misleading is caused to the antenna reverse detection result. Therefore, if the terminal is out of the coverage of the first network cell corresponding to the current interoperation record, the current interoperation record is deleted.
Correspondingly, if the terminal is located in the coverage area of the first network cell corresponding to the current interoperation record, step 4023 is executed.
It should be noted that, for each interoperation record, the above steps 4021 and 4022 are executed, or the steps 4021 and 4023 are executed to obtain a TA corresponding to each interoperation record, and determine whether to delete the corresponding interoperation record. For a plurality of interoperation records that are not deleted, the following step 4023 is performed:
The first interoperation record is a record corresponding to the terminal when the terminal is switched or redirected to a certain first network cell from a second network cell, and the second interoperation record is a record corresponding to the terminal when the terminal falls back to the certain first network cell from a second network cell circuit domain.
Specifically, each interoperation record is traversed, and a matching value between the first network cell and the second network cell in each interoperation record is calculated, wherein a specific calculation formula is as follows:
wherein M isu,vDenotes a matching value, C, between the second network cell u and the first network cell vu,vNumber of second interoperation records, C, between second network cell u and first network cell vuNumber of pieces, C, representing second interoperation records corresponding to second network cell uuIs Cu,vAnd the sum of the number of second interoperation records between the second network cell u and the other first network cells, Ru,vNumber of entries, R, representing a first interoperation record between a second network cell u and a first network cell vuIndicating the number of first interworking records corresponding to the second network cell u,
denotes the weighting coefficient of the second interoperation record, and ω denotes the weighting coefficient of the first interoperation record. Here, the weighting factor of the second interoperation record
And the weighting factor used for adjusting the influence of the second interoperation record on the matching value, wherein the weighting factor may be different between different cells and in different application scenarios. The weighting factor omega of the first interoperation record is used for adjusting the proportion of the influence of the first interoperation record on the matching value.
Obtaining a matching value according to the number of first interoperation records and/or the number of second interoperation records between a second network cell and a certain first network cell, including: and obtaining a matching value according to the number of the first interoperation records between the second network cell and the first network cell, or obtaining a matching value according to the number of the second interoperation records between the second network cell and the first network cell, or obtaining a matching value according to the number of the first interoperation records and the second interoperation records between the second network cell and the first network cell.
Wherein, when in the formula (4)
The matching value is obtained according to the number of the first interoperation records between the second network cell and the first network cell.
When ω in equation (4) is 0, it means that a matching value is obtained from the number of pieces of the second interoperation record between the second network cell and the first network cell.
When ω in the formula (4) is not 0, and
and when the number is not 0, the matching value is obtained according to the number of the first interoperation records and the second interoperation records between the second network cell and the first network cell.
Because the areas where the terminals are located are different, the terminals with higher frequency of executing a certain service may be intensively distributed in a certain geographical area, and when the interoperation is performed, the difference between the number of first interoperation records generated when the terminals are switched or redirected to the first network cell and the number of second interoperation records generated when the terminals fall back to the first network cell through the circuit domain is larger, so that the matching value of the first network cell and the second network cell is influenced. Referring to fig. 9, fig. 9 shows a centralized distribution scenario of voice traffic in a network cell. In the scenario shown in fig. 9, u is 1, v is 1, z is 2, the 4G cell 1 corresponds to the same sector 3G cell 1, the 4G cell 2 corresponds to the same sector 3G cell 2, and a plurality of voice service high-speed office buildings exist at the junction of the coverage areas of the 3G cell 1 and the 3G cell 2. Due to the fact that voice service in office buildings is high in transmission and the number of calls is large, the total number of times that the terminal falls back to the 3G cell due to the voice service circuit domain is far more than the number of times that the terminal is redirected or switched to the 3G cell due to network coverage. Moreover, since the terminal is at the handover between the coverage of the 3G cell 1 and the coverage of the 3G cell 2, after the terminal leaves the 4G cell 1, the probability of selecting access to the 3G cell 1 is equivalent to that of the 3G cell 2, or the terminal selects accessThe probability of entering the 3G cell 1 is greater than the probability of accessing the 3G cell 2, or the probability of selecting to access the 3G cell 1 is less than the probability of accessing the 3G cell 2. When the probability of selecting to access the 3G cell 1 is smaller than the probability of accessing the 3G cell 2, the interoperation based on the voice service between the 4G cell and the 3G cell 1 is correspondingly less, the number of second interoperation records is also less, the interoperation based on the voice service between the 4G cell and the 3G cell 2 is correspondingly more, the number of second interoperation records is also more, and further C is caused1,1/C1Small value, C1,2/C1Large value, influence M1,1And M1,2The relative size further affects the result of the antenna reverse detection. Here, by setting the weighting factor of the second interoperation record (i.e., the record generated when the terminal falls back from the 4G cell circuit domain to the 3G cell)
Such as
Weakening of Cu,v/CuTo Mu,vAnd C, andu,z/Cuto Mu,zThe calculated matching value is more accurate, and misjudgment is reduced.
For the second network cell and a certain first network cell, the above step 4023 may be executed to obtain a matching value between the second network cell and the first network cell until obtaining a matching value between the second network cell and each first network cell.
Specifically, the matching value is maximized and exceeds the matching value threshold MthAs a matching first network cell corresponding to the second network cell. Matching the first network cell satisfies the following relationship:
wherein the content of the first and second substances,
representing the matching first network cell corresponding to the second network cell u, V representing the set of the first network cells V which the terminal may access after departing from the second network cell u, Cu,vNumber of second interoperation records, C, between second network cell u and first network cell vuNumber of pieces, R, representing generation of second interoperation record of second network cell uu,vNumber of entries, R, representing a first interoperation record between a second network cell u and a first network cell vuIndicating the number of pieces of the second network cell u that generated the first interworking record,
represents the weighting factor of the second interoperation record, ω represents the weighting factor of the first interoperation record,
indicating that the second network cell u matches the first network cell
Match value between, MthRepresenting a match value threshold.
Here, the matching value threshold MthAnd the device is used for filtering out the first network cell with a lower matching value with the second network cell in the process of determining the matching first network cell corresponding to the second network cell. Optionally, the value range is: m is more than 0.5thIs less than 1. Setting a matching value threshold MthThe reason for this is that: in the actual distribution of the second network cells, there is a certain deviation between the direction of the sector to which the respective second network cell belongs and the direction of the sector to which the preconfigured first network cell belongs, but the second network cell antennas are not yet inverted. At this time, through calculating the matching value, the second network cell may have two or more suspected matching first network cells corresponding to the second network cell, but the two suspected matching first network cellsThe matching values of the network cells are all small, and at this time, if the first network cell with the largest matching value is taken as the matching first network cell corresponding to the second network cell, misjudgment may exist. By setting a matching value threshold MthThe first network cell with a lower matching value with the second network cell can be filtered, and misjudgment caused by the deviation of the direction of the sector of the second network cell and the direction of the sector of the first network cell is avoided.
Optionally, the corresponding relationship between the second network cell identifier and the corresponding matching first network cell identifier of the second network cell is stored in the first cell matching table, so as to facilitate subsequent query or correlation operation. Here, each network cell is provided with a Physical Cell Identifier (PCI) to facilitate planning and configuration of a handover relationship, and improve network connection quality. The first cell matching table is specifically shown in table 3:
TABLE 3
Step 403 determines whether the antenna of the second network cell is reverse connected according to the preconfigured first network cell of the second network cell and the matching first network cell of the second network cell.
Step 403 may be implemented as the following steps:
If the matching first network cells corresponding to the second network cell and the second network cell belong to the same physical site, the matching first network cells corresponding to the second network cell and the second network cell are reserved, and step 4032 is executed. If the matching first network cell corresponding to the second network cell and the second network cell do not belong to the same physical site, then step 4033 is executed.
For example, if the pre-configured 3G cell of the 4G cell is 3G cell 1, and the matching 3G cell of the 4G cell is obtained by calculating the matching value and is 3G cell 1, it indicates that the antenna of the 4G cell is not inverted.
Optionally, for the first cell matching table, a preconfigured first network cell corresponding to the second network cell is added to the first cell matching table to form a second cell matching table. The second cell matching table is specifically shown in table 4:
TABLE 4
Thus, referring to table 4 above, it is possible to obtain whether the matching first network cell and the preconfigured first network cell are consistent by querying table 4 above, and further intuitively determine whether the antenna of the second network cell is reversely connected.
As a possible implementation manner, the antenna reverse detection method is described below with reference to table 4 above:
first, a counter for counting abnormal cells (i.e., second network cells with inverted antennas) is set to zero, i.e., Count is 0.
Traversing the second network cells u in sequence for each second cell matching tableiThe second network cell u is recordediMatching the first network cell as vm,iThe second network cell uiIs vp,i。
If presentvm,i≠vp,iThen label the second network cell uiIs an abnormal cell, and the counter is increased by 1, i.e. Count is 1.
After traversing all the second network cells of the same physical site, if Count is greater than 1 and the following conditions exist, determining that the second network cell antenna of the physical site has an inverse connection condition:
wherein u isi，ujIndicating a different second network cell, vm,iIndicating a second network cell uiIs matched to the first network cell, vp,jIndicating a second network cell ujV is pre-configured with the first network cellm,i＝vp,jRepresents uiIs matched to the first network cell vm,iAnd ujIs pre-configured with a first network cell vp,jThe same; similarly, vm,j＝vp,iRepresents ujIs matched to the first network cell vm,jAnd uiIs pre-configured with a first network cell vp,iThe same is true.
Or, if Count > 1 and the following conditions exist, determining that the second network cell antenna of the physical site is in a reverse connection condition:
wherein u isi、uj、ukIndicating a different second network cell, vm,iRepresents uiIs matched to the first network cell, vp,iRepresents uiV is pre-configured with the first network cellm,kRepresents ukIs matched to the first network cell, vp,kRepresents ukV is pre-configured with the first network cellm,jRepresents ujIs matched to the first network cell, vp,jRepresents ujV is pre-configured with the first network cellm,i＝vp,kRepresents uiIs matched to the first network cell vm,iAnd ukIs pre-configured with a first network cell vp,kThe same; v. ofm,j＝vp,iRepresents ujIs matched to the first network cell vm,jAnd uiIs pre-configured with a first network cell vp,iThe same; v. ofm,k＝vp,jRepresents ukIs matched to the first network cell vm,kAnd ujIs pre-configured with a first network cell vp,jThe same is true.
In the practical application process, if a physical site pre-configured with a first network cell fails and no signal is output, at this time, when the terminal is separated from a second network cell and needs to access a certain first network cell, the probability of accessing the first network cell of another physical site is increased. This is not considered in the reverse antenna detection method according to the embodiments of the present application. Optionally, the second network cell not belonging to the same physical site and the matching first network cell corresponding to the second network cell need to be deleted.
Optionally, the second network cell identifier that does not belong to the same physical site and the matching first network cell identifier corresponding to the second network cell are deleted from the first cell matching table.
According to the antenna reverse connection detection method provided by the embodiment of the application, after the interoperation records of the first network cell and at least one first network cell are obtained, the interoperation records are utilized to determine the matched first network cell of the second network cell, and whether the antenna of the second network cell is reverse connected or not is determined according to the pre-configured first network cell of the second network cell and the matched first network cell of the second network cell. Compared with the prior art that a large amount of data needs to be processed in an iterative mode to determine whether the antenna is reversely connected, the antenna reverse connection detection method provided by the embodiment of the application determines the matching first network cell of the second network cell by using a perfect first network as a second network calibration basis and using interoperation records between different network systems, and determines whether the antenna of the second network cell is reversely connected by combining with the pre-configured first network cell of the second network cell, so that the operation process is simplified, and the accuracy is high.
