It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0037] Figure 2 is a flow chart of a method for monitoring a pico base station according to an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0038] Step S202, in response to monitoring that the pico base station is in a network connection state, the current tunnel information, historical neighbor cell switching data and current neighbor cell switching data of the pico base station are obtained, wherein the historical neighbor cell switching data is used to characterize the neighbor cell switching data within a first preset time period before the network link of the pico base station is interrupted, and the current neighbor cell switching data is used to characterize the neighbor cell switching data within a second preset time period after the network link is interrupted.

[0039] Among them, the current tunnel information may include but is not limited to the pico base station MAC (Media Access Control, network card address), the pico base station local IP (Internet Protocol Address, network protocol address), and the pico base station serial number. The first preset time period may be a period of time preset in advance, for example, it may be 1-3 days, and the second preset time period may be the same as the first preset time period.

[0040] Specifically, obtaining the current tunnel information may include: collecting the current tunnel information of the pico base station, sending an acquisition instruction to the pico base station, and the message content includes three information: "Pico base station MAC", "Pico base station local IP", and "Pico base station serial number". Among them, "Pico base station local IP" is the IP address assigned by the pico base station to obtain the upper-layer routing. Parse the source IP in the message header to parse the actual IP address accessed, which is defined as the "access IP". By determining the consistency of the "access IP" and the "Pico base station local IP", the configuration method of the optical modem and the pico base station is defined, and the field name is "Optical modem and pico base station access method".

[0041] If "Access IP" = "Local IP of Pico Base Station", the optical modem and the Pico base station are in bridging mode, and the field value is "Bridge Mode"; if "Access IP" ≠ "Local IP of Pico Base Station", the optical modem and the Pico base station are in routing mode, and the field value is "Routing Mode".

[0042] Obtain the key information of the entire node of the pico base station. The pico base station security monitoring function can clearly belong to the MSE (Multi-Service Edge) by confirming the IP segment where the "access IP" is located. According to the affiliated MSE and the access IP, the corresponding MSE-OLT terminal (Optical Line Terminal) downlink port is obtained, and the affiliated OLT is obtained according to the MSE-OLT downlink port; obtain the MAC information of the access IP on the MSE side. They are defined as "TE-IPaddress", "TE-MAC" and "MSE-OLT-Interface" respectively. Through the affiliated OLT, according to the TE-MAC, the PON (Passive Optical Network) port number, ONU (Optical Network Unit) number and VLAN (Virtual Local Area Network) number where the TE-MAC is located are obtained. They are defined as "Optical Modem PON Port", "Optical Modem ONU Number" and "TE-VLAN" respectively. On the OLT side, the broadband identification code and MAC information of the optical modem are obtained according to the "Optical Modem PON Port" and "Optical Modem ONU Number" fields. They are defined as "LOID (optical modem broadband identification code)" and "optical modem MAC" on the OLT side, and the MAC and VLAN information of the equipment under the optical modem are obtained according to the "optical modem PON port" and "optical modem ONU number" fields. They are defined as "end-end device MAC" and "end-end device VLAN" respectively. According to the above five steps, the full-process routing information matrix table of the pico base station is obtained as shown in Table 1.

[0043] Table 1 Pico base station full-route routing information matrix

[0044]

[0045] According to the routing connection method, the OLT side cannot obtain the MAC of the next-level device beyond the optical modem. The "TE-MAC" obtained is only the MAC of the optical modem's own specific WAN connection. In the matrix table, "Pico base station MAC" ≠ "TE-MAC" = "end device MAC". According to the bridging method, the PON network is a transparent bearer channel. In the matrix table, "Pico base station MAC" = "TE-MAC" = "end device MAC".

[0046] Step S204, based on the current tunnel information, determine the binding relationship between the pico base station and the optical modem.

[0047] Specifically, determining the binding relationship between the pico base station and the optical modem includes: extracting the correspondence T of "[optical modem and pico base station access method] + [pico base station local IP] + [pico base station MAC] + [TE-MAC] + [optical modem broadband identification code] + [end device MAC]" according to the full routing information table of the pico base station, and judging the binding relationship between the pico base station and the optical modem based on the corresponding relationship.

[0048] Step S206, compare the historical neighbor cell switching data with the current neighbor cell switching data to determine the location status of the pico base station, wherein the location status is used to characterize the distance between the current physical location of the pico base station and the original physical location of the pico base station.

[0049] The current physical location may be the specific location where the pico base station is currently located, and the original physical location may be the specific location where the pico base station was initially located without any movement.

[0050] Specifically, comparing the historical neighboring cell switching data with the neighboring cell switching data N days after the interruption to determine the location status of the pico base station may include: the pico base station link is interrupted, and the historical neighboring cell switching data is obtained, and the summarized format is shown in Table 2 below:

[0051] Table 2 Summary of historical neighbor cell handover data

[0052]

[0053] According to the number of hand-offs and hand-ins, the target cells are classified into all target cells x0, strongly correlated adjacent cells Y0 and non-strongly correlated adjacent cells Z0.

[0054] After the pico base station link is reconnected, the neighboring cell handover data of M days after the interruption (it is recommended that the M value is equal to the above N value) is obtained, and the "all target cell set X" is obtained according to the above method. n , strongly correlated adjacent cell set Y n , non-strongly correlated adjacent cell set Z n .

[0055] By comparing "all target cell sets X o, strongly correlated adjacent cell set Y o , non-strongly correlated adjacent cell set Z o " and "all target cell sets X n , strongly correlated adjacent cell set Y n , non-strongly correlated adjacent cell set Z n " to determine whether the physical location of the pico base station has changed.

[0056] Step S208, based on the binding relationship and the location status, determine the monitoring result of the pico base station, wherein the monitoring result is used to characterize whether the location change of the pico base station meets a preset condition.

[0057] Among them, the preset condition can be understood as not considering the position change of the pico base station to be a random movement.

[0058] In an embodiment of the present application, in response to monitoring that the pico base station is in a network connection state, the current tunnel information, historical neighbor cell switching data and current neighbor cell switching data of the pico base station are obtained, and then based on the current tunnel information, the binding relationship between the pico base station and the optical modem is determined, the historical neighbor cell switching data and the current neighbor cell switching data are compared to determine the position status of the pico base station, and finally based on the binding relationship and the position status, the monitoring result of the pico base station is determined. It should be noted that the historical neighbor cell switching data is used to characterize the neighbor cell switching data within the first preset time period before the network link of the pico base station is interrupted, and the current neighbor cell switching data is used to characterize the neighbor cell switching data within the second preset time period after the network link is interrupted; by comparing the neighbor cell switching data within the first preset time period before the network link is interrupted with the neighbor cell switching data within the second preset time period after the network link is interrupted, the distance between the current physical position and the original physical position of the pico base station is obtained, and finally, combined with the binding relationship between the pico base station and the optical modem, the monitoring result is obtained, thereby achieving the purpose of detecting the position status of the pico base station in a wireless scenario, thereby realizing the technical effect of flexibly detecting whether the pico base station moves arbitrarily in a wireless scenario, thereby solving the technical problem that the related technology has poor flexibility in detecting whether the pico base station has arbitrary movement.

[0059] Optionally, in response to monitoring that the pico base station is in a network connection state, including: in response to the pico base station being powered on and the network link being unobstructed, determining whether the local network address of the pico base station changes from unreachable to reachable; in response to the local network address changing from unreachable to reachable, determining whether the pico base station changes from an alarm state to a non-alarm state; in response to the pico base station changing from an alarm state to a non-alarm state, determining whether the state of the pico base station is changed to an in-use state; in response to the state of the pico base station being converted to an in-use state, determining that the pico base station is in a network connection state.

[0060] Specifically, after the pico base station is powered on and the link is unblocked, when the network management determines that the IP has changed from unreachable to reachable, and the device has changed from alarm to no alarm, and the state has changed to in-use state, the pico base station tunnel information monitoring is carried out, and the pico base station air interface neighboring area monitoring is carried out continuously for one to three days. When the link between the pico base station and the network is interrupted, the pico base station air interface neighboring area monitoring is also carried out at the same time, and the historical neighboring area switching data is saved.

[0061] Optionally, obtaining the current tunnel information of the pico base station includes: sending an acquisition instruction to the pico base station; receiving a feedback message returned by the pico base station through a bearer tunnel, wherein the feedback message includes: the pico base station physical address, local network address and serial number of the pico base station; parsing the source network address in the header of the feedback message to obtain the access address; determining the access method between the pico base station and the optical modem by judging the consistency between the local network address and the access address; obtaining the current tunnel information based on the pico base station physical address, local network address, serial number, access address and access method.

[0062] Specifically, obtaining the current tunnel information of the pico base station may include: sending an acquisition instruction to the pico base station, and the message content includes three information: "Pico base station MAC", "Pico base station local IP", and "Pico base station serial number". Among them, "Pico base station local IP" is the IP address assigned by the pico base station to obtain the upper-layer routing. Parse the source IP of the message header to parse the actual IP address accessed, which is defined as the "access IP". By determining the consistency of the "access IP" and the "Pico base station local IP", the configuration method of the optical modem and the pico base station is defined, and the field name is "Optical modem and pico base station access method". If "Access IP" = "Pico base station local IP", the optical modem and the pico base station are in bridging mode, and the field value is "Bridging mode"; if "Access IP" ≠ "Pico base station local IP", the optical modem and the pico base station are in routing mode, and the field value is "Routing mode".

[0063] Optionally, based on the current tunnel information, the binding relationship between the pico base station and the optical modem is determined, including: based on the current tunnel information, obtaining the full-length node key information of the pico base station, wherein the full-length node key information includes: the current tunnel information, the edge routing information of the multi-service edge corresponding to the pico base station, the optical modem routing information of the optical modem and the device routing information of the terminal device, and the terminal device is used to characterize the devices under the optical modem; based on the full-length node key information, a target correspondence relationship is generated, wherein the target correspondence relationship is used to characterize the relationship between the access mode, the local network address, the physical address of the pico base station, the access physical address corresponding to the access address, the broadband identification code of the optical modem and the device physical address of the terminal device; based on the target correspondence relationship, the binding relationship is determined.

[0064] Specifically, based on the current tunnel information, determining the binding relationship between the pico base station and the optical modem can include: extracting the correspondence T of "[optical modem and pico base station access method] + [pico base station local IP] + [pico base station MAC] + [TE-MAC] + [optical modem LOID] + [end device MAC]" according to the full routing information table of the pico base station, and judging the binding relationship between the pico base station and the optical modem based on the corresponding relationship.

[0066] Specifically, based on the current tunnel information, the key node information of the whole process of the pico base station is obtained, which may include: the pico base station security monitoring module, by confirming the IP segment where the "access IP" is located, clearly belongs to the MSE.

[0088] Specifically, based on the target corresponding relationship, determining the binding relationship may include: defining the corresponding relationship of the initial access to the network as T0, defining the corresponding relationship after the intermediate recalibration as T0, T n (n>0, and is an integer) is the number of subsequent collections.

[0089] Optionally, historical neighbor cell switching data and current neighbor cell switching data are compared to determine the location status of the pico base station, including: based on the first switching number in the historical neighbor cell switching data, historical target cells in the historical neighbor cell switching data are classified to obtain a first cell set, wherein the first switching number is used to characterize the total number of switching requests for switching in and out of the historical target cells; based on the second switching number in the current neighbor cell switching data, current target cells in the current neighbor cell switching data are classified to obtain a second cell set; the first cell set and the second cell set are compared to determine the location status of the pico base station.

[0090] The first cell set may be different types of historical target cells, the second cell set may be different types of current target cells, and the second switching number may be the total number of switching requests for the current target cell.

[0091] Specifically, the target cells may be classified into all target cells X0, strongly correlated adjacent cells Y0 and non-strongly correlated adjacent cells Z0 according to the number of hand-outs and hand-ins.

[0092] Optionally, based on the first switching number in the historical neighboring area data, the historical target cells in the historical neighboring area switching data are classified to obtain a first cell set, including: determining the historical target cells whose first switching number is greater than a preset number as first category cells; determining the second category cells from the historical target cells, wherein the sum of the first switching numbers of the second category cells is greater than or equal to the sum of the first switching numbers of the historical target cells; determining the cells in the historical target cells other than the second category cells as third category cells; and obtaining the first cell set based on the first category cells, the second category cells and the third category cells.

The first category cells can be all target cells, the second category cells can be strongly correlated adjacent cells, and the third category cells can be non-strongly correlated adjacent cells.

[0094] Specifically, the set of all target cells with a total number of cut-in and cut-out requests greater than 0 can be defined as X0; the set of strongly correlated adjacent cells is defined as Y0, and the set of non-strongly correlated adjacent cells is defined as Z0. Taking the target cell as the granularity, sorting by the total number of cut-in and cut-out from high to low, each target cell can be assigned a number from 1 to N: cell 1, cell 2....., cell n

[0095] The accumulated value is accumulated one by one from cell 1, and the total value is exactly greater than "the sum of the total number of hand-in and hand-out requests of all target cells * 80%";

[0096]

[0097] Wherein: handover is the total request for handover of each target cell; if n=h, then the strongly correlated adjacent cell set Y0 is the set of cells numbered from 1 to h; and the non-strongly correlated adjacent cell set Z0 is the set of cells numbered from h to n.

[0098] Optionally, in response to the first cell set and the second cell set satisfying any one of the following conditions, the location state is determined to be a distance less than or equal to a first preset distance: the first category cells in the first cell set are the same as the first category cells in the second cell set, and the second category cells in the first cell set are the same as the second category cells in the second cell set; the first category cells in the first cell set are included in the first category cells in the second cell set, and the second category cells in the first cell set are included in the second category cells in the second cell set; the first category cells in the second cell set are included in the first category cells in the first cell set, and the second category cells in the second cell set are included in the second category cells in the first cell set.

[0100] Specifically, the position of the pico base station can be considered unchanged when the following three situations occur: n =X0 and Y n =Y0, then the target cells in the two sets are exactly the same, and the location of the pico base station remains unchanged; if X n ∈x0 and Y n ∈Y0, then X0 and Y n The target cell is completely contained in X0 or Y0. The possible reason is that the location of the pico base station remains unchanged, and the trajectory of users accessing the pico base station changes, reducing the handover relationship with some cells; if X0∈X n And Y0∈Y n , then x0 and Y0 target cells are completely contained in x n or Y n The possible reason is that the location of the pico base station remains unchanged, but the trajectory of users accessing the pico base station changes, which increases the handover relationship with some cells.

[0101] Optionally, in response to the first cell set and the second cell set satisfying any one of the following conditions, the location state is determined to be a distance greater than or equal to a second preset distance: the first category of cells in the first cell set is different from the first category of cells in the second cell set; the second category of cells in the first cell set is different from the second category of cells in the second cell set; the third category of cells in the second cell set and the first category of cells in the first cell set include multiple identical cells.

[0103] Specifically, the Pico base station can be considered to be far away from the original installation location when the following situations occur: n ≠x0, the two target cells are completely different and the pico base station is far away from the original installation location; if Y n ≠Y0 or Z n ∩X0>1, the two sets of strongly correlated target cells are completely different, but there is overlap of non-strongly correlated target cells, and the pico base station is far away from the original installation location but not far away. n ∩X0: Whether the total number of cut-in and cut-out increases and reaches the set Y n In the example above, the direction in which the pico base station is moved can be determined.

[0104] Optionally, in response to the first cell set and the second cell set satisfying any one of the following conditions, the location state is determined to be a distance greater than a first preset distance and less than a second preset distance: the number of identical cells contained in the second category cells in the first cell set and the second category cells in the second cell set is less than a target number, and the third category cells in the first cell set are different from the second category cells in the second cell set, and the target number is used to represent the product of the second category cells in the first cell set and a preset value.

[0105] Specifically, the Pico base station can be considered to have deviated from the original installation position when the following situations occur: n The number of intersections of ∩Y0 is less than 50% of Y0, and Z0∈Y n If the number of cell switching in and out increases, the pico base station is offset in a small range.

[0106] Optionally, based on the binding relationship and the location status, the monitoring result of the pico base station is determined, including: in response to the binding relationship remaining unchanged and the location status being a distance less than a second preset distance, determining that the monitoring result is that the location change of the pico base station meets a preset condition; in response to the binding relationship remaining unchanged and the location status being a distance greater than or equal to a second preset distance, determining that the monitoring result is that the location change of the pico base station does not meet the preset condition; in response to a change in the binding relationship, determining that the monitoring result is that the location change of the pico base station does not meet the preset condition.

[0107] Specifically, based on the binding relationship and position status, the monitoring results of the pico base station are determined, which may include: if the binding relationship between the pico base station and the optical modem remains unchanged, and the position of the pico base station remains unchanged or deviates, it is judged to be normal.

[0108] If the binding relationship between the Pico base station and the optical modem remains unchanged, but the location of the Pico base station is far away from the original installation location, it is judged to be abnormal and it is necessary to verify on site whether it is deployed too far away and exceeds the planned area.

[0109] If the binding relationship between the pico base station, the optical modem and its standard address changes, it is judged to be abnormal and further judged that the position of the pico base station is offset.

[0110] If the Pico base station and the bound optical modem change or remain unchanged, the optical modem may have been replaced.

[0111] If the Pico base station is far away from the original installation location, the Pico base station will be moved to another area for use, which is far away from the original installation location.

[0112] If the Pico base station deviates from the original installation location, the Pico base station will be moved to another area for use, not far from the original installation location.
