Description

Multi-standard network control method and network management equipment

Technical Field

The present application relates to the field of wireless communications technologies, and in particular, to a multi-system network control method and a network management device.

Background

The energy consumption of the wireless communication system is higher in the network operation cost, and especially, how to more economically utilize different networks to provide services and reduce the operation cost under the condition that multiple standard networks coexist, such as a current global system for mobile communication (GSM), a Universal Mobile Telecommunications System (UMTS), a Long Term Evolution (LTE) network, and the like, has become a hot spot concerned in the industry.

In the prior art, corresponding energy-saving strategies are formulated for different standard networks, and when the corresponding standard networks meet the turn-off conditions, the cells of the standard networks are turned off, so that the purpose of energy saving is achieved. However, with the GUL spectrum reforming (refarming), the radio frequency common mode ratio of the multi-system network is continuously increased, and the existing energy-saving strategies of different-system networks are independent from each other, so that the existing energy-saving strategies are difficult to take effect, and the energy-saving effect is not obvious. For example, when the 1800MHz band G1800 of the GSM network and the 1800MHz band L1800 of the LTE network share a Radio Frequency (RF) module, if G1800 does not satisfy the corresponding turn-off condition, even if L1800 satisfies the corresponding turn-off condition, the turn-off cannot be performed.

The present application provides a multi-system network control method and a network management device, which can be applied to a network management system 100 shown in fig. 1, where the network management system includes a network management device 110 and at least one base station 120, and the base station 120 supports multiple network systems. The network management device 110 is mainly used for managing and maintaining the at least one base station 120, for example, the network management device 110 may reset the base station 120, or check the operation state of the base station 120, or monitor the operation state of the base station 110, optimize the base station 110, and the like. The network management device 110 may specifically be a server.

The base station 120 is a radio transceiver station for performing information transmission with a user equipment through a mobile communication switching center, and may specifically be an evolved node B (eNB), a macro base station, a micro base station (also referred to as a "small base station"), a pico base station, an Access Point (AP), a Transmission Point (TP), or the like, or may also be a base station in a future network, such as a base station in a 5G network.

Further, the network with multiple systems supported by the base station 120 includes, but is not limited to, two or more of the following network systems: a 2nd-Generation wireless telephone technology, 2G network, a 3rd-Generation wireless telephone technology, 3G network, a 4th-Generation wireless telephone technology, 4G network, and a 5th-Generation wireless telephone technology, 5G network, and so on. Such as a global system for mobile communications (GSM) network, a Code Division Multiple Access (CDMA) network, a Wideband Code Division Multiple Access (WCDMA) network, a Universal Mobile Telecommunications System (UMTS) network, a Long Term Evolution (LTE) network, etc.

The application provides a multi-standard network control method, which is applied to a network management device shown in fig. 1, and as shown in fig. 2, aiming at any one of the multi-standard networks supported by a base station managed by the network management device, the network management device executes the following steps:

s201: acquiring engineering parameters and configuration parameters of each cell in a base station managed by the network management equipment;

the network with multiple systems supported by the base station includes, but is not limited to, two or more of the following network systems: 2G networks, 3G networks, 4G networks, 5G networks, and the like. The engineering parameters of the base station include, but are not limited to, parameters such as an azimuth angle, a downtilt angle, a longitude (longitude), a latitude (latitude), an Identification (ID) of the base station, and a name of the base station. The configuration parameters of the base station include, but are not limited to, cell information included in the base station, whether a cell of the base station supports voice over long-term evolution (VoLTE), whether a cell of the base station supports narrowband internet of things (NB-IoT) service, whether a cell of the base station is a Radio Remote Unit (RRU) cell, whether a cell of the base station supports (CSFB), whether a cell of the base station is a frequency point or a neighboring cell of the CSFB, whether a cell of the base station supports voice over long-term evolution (VoLTE), and co-coverage parameters.

S202: determining a first type frequency band and a second type frequency band from a plurality of working frequency bands corresponding to the standard network according to engineering parameters and configuration parameters of a cell supporting the standard network, wherein the cell corresponding to the first type frequency band meets continuous coverage, the proportion of terminal equipment supporting the first type frequency band in the cell corresponding to the second type frequency band is greater than a set value, and the first type frequency band meets interoperation between the standard network and other standard networks;

if the successful inter-station co-frequency switching times of the cells corresponding to the first frequency band are greater than the successful inter-frequency switching times of the cells corresponding to the first frequency band, the cells corresponding to the first frequency band meet continuous coverage. The first-class frequency band satisfies the interoperability between the standard network and other standard networks, including the interoperability of data services occurring when data services are switched between networks (for example, the interoperability of data services occurring to ensure the continuity of data services when user equipment using data services is switched between a 4G network and a 2G/3G network), and the interoperability of voice services occurring when voice services are switched between networks (for example, the voice services of the 4G network fall back to the 2G/3G network).

The ratio of the terminal devices supporting the first frequency band in the cell corresponding to the second frequency band may be represented by a ratio of the number of the terminal devices supporting the first frequency band in the cell corresponding to the second frequency band to the total number of the terminal devices in the second frequency band, and the set value may be 90%. Specifically, the network management device may identify, through an average number and a total number of users in each frequency band in a Dedicated Channel (DCH) state of the cell, a ratio of each frequency band supported by the terminal device in the cell, so as to determine a ratio of the terminal device supporting the first frequency band in the cell corresponding to the second frequency band. For example, for a scenario in which the UMTS network includes the 900MHz Band U900 and the 2100MHz Band U2100, the terminal penetration rate of the U2100 CELL is equal to vs.celldchus.band 8/vs.celldchus.band total, where vs.celldchus.band 8 denotes the average number of users in the CELL that support Band8 in the CELL _ DCH state, and vs.celldchus.band total denotes the total number of users in the CELL that support each Band in the CELL _ DCH state.

S203: and controlling the base station to reserve the first frequency band and turn off the second frequency band.

Specifically, in step S201, the network management device obtains a configuration file of a base station managed by the network management device, and obtains an engineering parameter of the base station and a configuration parameter of the base station from the configuration file. Since there are separate master stations (physical base stations) in the existing communication network, different logical base station profiles are also independent of each other in such stations, but cells in different logical base stations may share a Radio Frequency (RF) module. Therefore, it is necessary to identify a scene in which cells in a logical base station share a radio frequency module, establish a relationship between a starting point and the logical base station, and further establish a mapping relationship between the logical cells and the radio frequency module, so that the network management device can determine an actual base station corresponding to each logical cell from an obtained configuration file of the base station.

In specific implementation, the network management device identifies the name of the base station, the identifier of the base station, the identifiers of the cells of the base station, and the cabinet frame slot numbers of the radio frequency modules corresponding to the cells from the obtained configuration file of the base station, and establishes a mapping relationship between the network cells of different systems and the cabinet frame slot numbers of the radio frequency modules, so as to judge whether the network cells of different systems are physically co-located and share the RF modules, thereby obtaining a better energy saving effect.

For example, the network management device obtains the mapping relationship between the cell corresponding to the LTE network in the managed base station and the cabinet frame slot number of the radio frequency module through the following steps:

1. reading eNodeB information from a base station configuration file < eNodeB function > (eNodeB function) element, wherein the eNodeB information comprises an eNodeB name (eNodeB BFunction name) and an eNodeB identification (eNodeB ID);

2. reading information of each cell of a site from a base station configuration file < cell > (cell) element, wherein the information comprises a local cell identifier (LocalCellId), a cell identifier (CellId), a cell duplex mode (FddTddInd), an NB-IoT cell indication (NbCellFlag) and a cell bandwidth (DlBandWidth), and confirming a specific working mode of each cell of LTE;

3. reading the corresponding relation between each LTE cell and sector equipment (SECTOREQMID) from an element of a base station configuration file < eUCell SectorEqm > (cell sector equipment) according to a local cell identifier (LocalCellId);

4. acquiring a tank frame slot number of a radio frequency module from a base station configuration file: a. for an ANTCFGMODE (antenna configuration mode) as an ANTENNAPORT (antenna port) configuration mode, reading RF module cabinet frame numbers corresponding to transmitting antenna ports (ANTTYPE is equal to 2 or 3) of each sector equipment (SECTOREQMID) from a base station configuration file < SECTOREQM > (sector equipment) element; b. for an ANTCFGMODE (antenna configuration mode) which is a BEAM configuration mode, RRUCN (RRU cabinet number), RRUSRN (RRUSRN frame number) and RRUSN (RRU slot number) respectively represent cabinet frame slot numbers corresponding to the RF modules;

5. and establishing a mapping relation between the LTE network cell and the RF module according to the acquired base station information, cell information and the cabinet frame slot number corresponding to the RF module.

The network management device establishes a mapping relationship between the network cell of other systems and the RF module, which is similar to the method for establishing a mapping relationship between the LTE network cell and the RF module, and reference may be made to the description of the method for establishing a mapping relationship between the LTE network cell and the RF module, which is not repeated herein.

Further, the network management device may also determine whether cells corresponding to networks of different systems are Macro cells through a base station configuration file, and may be represented by a parameter "Is Macro". Specifically, for a 2G network (such as a GSM network), the base station Is set outdoors, and then a Macro (Macro) cell Is defaulted, and at this time, the "Is Macro" parameter of the cell Is "Yes"; for a 3G network (such as a UMTS network), if the maximum transmitting power MaxTxxPower of a cell Is more than or equal to 10w, the cell Is a Macro cell, and at the moment, the parameter "Is Macro" corresponding to the cell Is "Yes"; for a 4G network (such as an LTE network), whether a cell Is a MACRO cell Is determined according to a feedback result of a cell MACRO-attribute command "dspcelllcs (MACRO-cell), MICRO (MICRO-cell) or NA (invalid value), where the feedback result Is MACRO (indicating MACRO-cell), when the feedback result Is MACRO, a parameter" ismaro "corresponding to the cell Is" Yes ", and when the feedback result Is other values except MACRO, the parameter" Is MACRO "corresponding to the cell Is" No ".

The network management equipment can also determine whether the cells corresponding to the networks of different systems are indoor cells through the base station configuration file, and can be represented by a parameter "Is Lampsite". Specifically, for a 2G network, the parameter "Is mapping" of the cell Is NULL, which may be represented by "NULL"; for a 3G network (e.g., a UMTS network), if a cell configures ulocellceqmgrp, the cell Is an indoor cell, and a parameter "Is mapping" corresponding to the cell Is "Yes" at this time; for a 4G network (e.g., an LTE network), if a cell Is configured with a cell sector device group EuSectorEqmGroup and Is not configured with a cell sector device eucellsector, the cell Is an indoor cell, and a parameter "Is mapping" corresponding to the cell Is "No" at this time.

For a 4G network (e.g., an LTE network), the network management device may also determine whether a cell supports NB services through a base station configuration file, and may be represented by a parameter "Support NB". Specifically, the network management device determines whether the cell supports NB services by checking a parameter RB reservation mode RbRsvMode instructing cell RB reservation configuration cellrbbresserve, and if the parameter RbRsvMode takes the value NB _ deployent, it is considered that the LTE cell and the NB cell are co-deployed, that is, the NB services are supported, and at this time, a parameter "Support NB" corresponding to the cell is "Yes".

The network management equipment can also determine whether the cells corresponding to the networks of different systems Support the cell shared by multiple RRUs or not through the base station configuration file, and can be represented by a parameter 'Support SNF'. Specifically, for a 4G network (e.g., an LTE network), if a cell is shared by multiple RRUs in a base station configuration file to indicate that cell.multirurcellflag is configured as BOOLEAN _ TRUE, and a cell.multirurcellmode is configured as SFN or as MPRU _ aggregate (multiple MPRU AGGREGATION cell) in a base station configuration file, the cell supports the cell shared by multiple RRUs, and at this time, a parameter "Support" corresponding to the cell is "Yes SFN".

For a 4G network (e.g. an LTE network), the network management device may also determine whether a cell supports voice service (VoLTE service) through a base station configuration file, and may be represented by a parameter "Support VoLTE". Specifically, the network management device checks that a parameter EUTRAN in an eNodeB level algorithm switch supports a VoIP capability switch EutranVoipSupportswitch by checking a command eNodeB level algorithm switch ENODEBALGOSWITCH, and if the parameter EUTRAN is set to be 'ON', all LTE cells under the eNodeB support a Voice service.

For a 4G network (e.g. an LTE network), the network management device may also determine, through the base station configuration file, whether the cell supports CSFB from the 4G network to the 3G network, which may be represented by a parameter "Support L2U CSFB". Specifically, if eNodeB level and Cell level untrancsfbswitch is OFF, the Cell does not Support CSFB from the 4G network to the 3G network, and at this time, the parameter "Support L2U CSFB" corresponding to the Cell is "No", and if the parameter field does not exist, the Cell does not Support CSFB from the 4G network to the 3G network, and at this time, the parameter "Support L2U CSFB" corresponding to the Cell is "OFF"; if "BlindHoSwitch" in eNodeB or Cell level HoModeSwitch is not all 1, the Cell supports CSFB from 4G network to 3G network, and the parameter "Support L2U CSFB" corresponding to the Cell is the corresponding CSFB mode "Non Blind" (Non-Blind handover); if "blindowswitch" in eNodeB and Cell level HoModeSwitch is 1, the Cell does not Support CSFB from 4G network to 3G network, and the parameter "Support L2U CSFB" corresponding to the Cell is the CSFB mode "Redirection", "PS HO" (packet switch, PS) handover) or "CCOHO" (Cell change order, CCO) handover corresponding to the actual value of "csfbhopolicgcfg".

For a 4G network (e.g. an LTE network), the network management device may also determine, through the base station configuration file, whether the cell supports CSFB from the 4G network to the 2G network, and may be represented by a parameter "Support L2G CSFB". Specifically, if eNodeB and Cell level untrancsfbswitch are OFF, the Cell does not Support CSFB from the 4G network to the 2G network, where the parameter "Support L2G CSFB" corresponding to the Cell is "No", and if the parameter field does not exist, the Cell does not Support CSFB from the 4G network to the 2G network, where the parameter "Support L2G CSFB" corresponding to the Cell is OFF; if "BlindHoSwitch" in eNodeB or Cell level HoModeSwitch is not all 1, the Cell supports CSFB from 4G network to 2G network, and the parameter "Support L2G CSFB" corresponding to the Cell is the corresponding CSFB mode "Non Blind" (Non-Blind handover); if "blindowswitch" in eNodeB and Cell level HoModeSwitch is 1, the Cell supports CSFB from 4G network to 2G network, and the parameter "Support L2G CSFB" corresponding to the Cell is the corresponding CSFB mode "Redirection" (Redirection) or "PS HO" (PS handover), and if "Redirection" or "PS HO" is not included, the Cell supports CSFB from 4G network to 2G network, and the parameter "Support L2G CSFB" corresponding to the Cell is "Other" (indicating Other CSFB mode).

For the 3G network, the network management device may also determine, through the base station configuration file, whether the cell is a frequency point of the CSFB of the 4G network or an adjacent cell, and may be represented by a parameter "CSFB Target". Specifically, if the network management device determines that the 3G network cell and the 4G network cell are geographically co-located or co-located according to the mapping relationship between the 3G network cell and the RF radio frequency module and the mapping relationship between the 4G network cell and the RF radio frequency module, and the parameter "Support L2U CSFB" of the cell in the 4G network is not "No" or "Non Blind", further determining the parameter "CSFB Target" corresponding to the 3G network cell according to the switching manner between the 4G network and the 3G network, otherwise, the parameter "Support L2U CSFB" corresponding to the cell is NULL. If blind handover is adopted between the 4G network and the 3G network, the 3G network cell is a frequency point or an adjacent cell of a 4G network CSFB, the parameter 'CSFB Target' corresponding to the cell is CSFB BlindHO, and if the parameter field does not exist, the parameter 'CSFB Target' corresponding to the cell is NULL; if blind redirection is adopted between the 4G network and the 3G network, the 3G network cell is a frequency point or a neighboring cell of the 4G network CSFB, the parameter 'CSFB Target' corresponding to the cell is CSFB Freq, and if the parameter field does not exist, the parameter 'CSFBtarget' corresponding to the cell is NULL.

For the 2G network, the network management equipment can also determine whether the cell is a frequency point or an adjacent cell of the CSFB of the 4G network through the configuration file of the base station. Specifically, if the network management device determines that the 2G network cell and the 4G network cell are geographically co-located or co-located according to the mapping relationship between the 2G network cell and the RF radio frequency module and the mapping relationship between the 4G network cell and the RF radio frequency module, and the parameter "Support L2G CSFB" of the 4G network cell is not "No" or "Non Blind", further determining the parameter "CSFB Target" corresponding to the 2G network cell according to the switching manner between the 4G network and the 2G network, otherwise, the parameter "CSFB Target" corresponding to the cell is NULL. If blind handover is adopted between the 4G network and the 2G network, the parameter 'CSFB Target' corresponding to the 2G network cell is CSFB BlindHO, and if the parameter field does not exist, NULL is filled; c. if blind redirection is adopted between the 4G network and the 2G network, the parameter 'CSFB Target' corresponding to the cell is CSFB Freq, and if the parameter field does not exist, the parameter 'CSFB Target' corresponding to the cell is NULL.

It should be noted that the engineering parameters and configuration parameters of each cell in the base station managed by the network management device may be stored in one or more mapping relationship corresponding tables, and in step S201, the network management device may obtain the engineering parameters and configuration parameters of each cell in the base station managed by the network management device from the mapping relationship established and stored by the network management device, for example, the network management device may store a mapping relationship between a cell and an RF radio frequency module and a mapping relationship between a cell and a cell configuration parameter, or the network management device may store a mapping relationship between a cell and a cell engineering parameter and a configuration parameter.

Further, in step S203, the network management device turns off the second frequency band according to the turn-off priority of the second frequency band from high to low; wherein the turn-off priority of the second frequency band is proportional to the frequency of the second frequency band.

In a specific embodiment, since the macro cell has a larger power consumption than the indoor cell, in order to further improve the energy saving effect, the cell corresponding to the second frequency band determined by the network management device is the macro cell.

In a specific embodiment, when multiple remote radio units, RRUs, share a cell in a cell corresponding to the second frequency band, multiple RRUs share a cell in a cell corresponding to the first frequency band, so as to ensure consistent network coverage and further ensure network performance after the second frequency band is turned off.

In a specific embodiment, when the multiple network types supported by the base station include a 2G network, a 3G network, and a 4G network, the first frequency band and the second frequency band corresponding to the 2G network supported by the base station satisfy any one of the following conditions:

a. the frequency of the first frequency band corresponding to the 2G network supported by the base station is lower than the frequency of the second frequency band, and no frequency point or adjacent cell of circuit switched fallback of the 4G network exists in the second frequency band corresponding to the 2G network supported by the base station; alternatively, the first and second electrodes may be,

b. the frequency of a first frequency band corresponding to the 2G network supported by the base station is lower than the frequency of a second frequency band corresponding to the 2G network supported by the base station, and a frequency point or an adjacent cell of circuit switched fallback of the 4G network exists in the first frequency band corresponding to the 2G network supported by the base station; alternatively, the first and second electrodes may be,

c. the frequency of a first-class frequency band corresponding to a 2G network supported by the base station is lower than the frequency of a second-class frequency band corresponding to the 2G network supported by the base station, a frequency point or an adjacent cell of a circuit domain fallback of a 4G network does not exist in the first-class frequency band corresponding to the 2G network supported by the base station, a frequency point or an adjacent cell of the circuit domain fallback of the 4G network does not exist in the second-class frequency band corresponding to the 2G network supported by the base station, but a frequency point or an adjacent cell of the frequency band of the circuit domain fallback of the 4G network exists in the first-class frequency band corresponding to a 3G network supported by the base station.

For example, for a GSM network supported by the base station, the GMS network includes an 1800MHz frequency band G1800 and a 900MHz frequency band G900, the first class frequency band corresponding to the GSM network is G900, the second class frequency band corresponding to the GSM network is G1800, where a CSFB frequency point or a neighboring cell of the 4G network does not exist in G1800; or the first frequency band corresponding to the GSM network is G900, and the second frequency band corresponding to the GSM network is G1800, where a frequency point or an adjacent cell of a CSFB of a 4G network exists in G900; or the first frequency band corresponding to the GSM network is G900, the second frequency band corresponding to the GSM network is G1800, wherein a frequency point or a neighboring cell of CSFB of the 4G network does not exist in both G900 and G1800, and a frequency point or a neighboring cell of CSFB of the 4G network exists in the first frequency band corresponding to the UMTS network supported by the base station.

That is, the GSM network supported by the base station cannot be switched off in any of the following scenarios: i. a frequency point or an adjacent cell of the CSFB of the 4G network exists in the cell corresponding to G1800, that is, the cell "CSFB Target" corresponding to G1800 is not NULL, the cell "CSFB Target" corresponding to G900 of the same station (the same geographical station or the common RF module) is NULL, and the frequency point or the adjacent cell of the CSFB of the 4G network does not exist in the cell corresponding to the UMTS network of the same station, and the "CSFB Target" is NULL; the cell corresponding to the G1800 is a non-macro cell; iii, G1800 is absent.

In a possible implementation manner, the first class frequency band corresponding to the 3G network supported by the base station is a frequency point in which the number of cells in each working frequency band corresponding to the 3G network is greater than a set value. The first frequency band corresponding to the 3G network supported by the base station may be a frequency point with the largest number of cells in each working frequency band corresponding to the 3G network.

Further, when the multiple network types supported by the base station include a 2G network, a 3G network, and a 4G network, if the 4G network supported by the base station does not support the voice call service, and the 3G network supported by the base station supports the circuit domain fallback of the 4G network, a frequency point or an adjacent cell of the circuit domain fallback of the 4G network exists in a first-class frequency band corresponding to the 3G network supported by the base station; or, a frequency point or an adjacent cell of circuit switched fallback of the 4G network exists in the first class frequency band corresponding to the 2G network supported by the base station.

For example, for a UMTS network supported by the base station, the UMTS network includes 900MHz band U900 and 2100MHz band U2100. The network management equipment respectively determines the frequency points with the largest number of the cells in U900 and U2100 as the first class frequency band corresponding to the UMTS network supported by the base station according to the engineering parameters and the configuration parameters of the UMTS network supported by the base station, if the proportion of the terminal equipment supporting U900 in the cell corresponding to U2100 is less than 90%, the U2100 cannot be used as the second class frequency band corresponding to the UMTS network supported by the base station, and determines the other frequency points in U900 and U2100 except the first class frequency band corresponding to the UMTS network supported by the base station as the second class frequency band corresponding to the UMTS network supported by the base station, namely, the working frequency band corresponding to the UMTS network supported by the base station can only be used for carrier turn-off in the frequency band.

If the U900 or the U2100 does not exist, determining other frequency points in the U900 and the U2100 except for the first frequency band corresponding to the UMTS network supported by the base station as a second frequency band corresponding to the UMTS network supported by the base station, that is, the working frequency band corresponding to the UMTS network supported by the base station can only perform carrier turn-off in the frequency band; if the U900 or U2100 does not exist and only 1 frequency point exists in the frequency band, the UMTS network supported by the base station cannot perform energy saving optimization.

Further, when a co-coverage cell of U2100 exists in U900, if the network management device determines that a co-located (geographically co-located/co-RF module) LTE cell does not support Volte according to engineering parameters and configuration parameters of a UMTS network supported by the base station, and the parameter "CSFB Target" of the co-located UMTS cell is not always NULL, it indicates that the UMTS network supported by the base station supports CSFB from the LTE network to the UMTS network (L2U), at this time, the parameter "CSFB Target" of the cell corresponding to the first frequency band in U900 or U2100 must be non-NULL, that is, the cell corresponding to the first frequency band in U900 or U2100 supports L2UCSFB, the entire frequency band of U2100 can be used as the second frequency band corresponding to the UMTS network supported by the base station, otherwise, the parameter "CSFB Target" of the co-located GSM cell which is not turned off must be non-NULL (for example, G900 exists, or G1800 which does not participate in turn off), that is, that the parameter "CSFB Target" of the co-located GSM cell which is not turned off must be non-located in the neighboring frequency band corresponding to the GSM network 2U, otherwise, replacing the first class frequency band corresponding to the U900 with the frequency points with the same frequency band and the cells with multiple numbers. If the cells corresponding to the first-class frequency band in the U900 still cannot support L2U CSFB after being replaced one by one, the operating frequency band corresponding to the UMTS network supported by the base station may only perform carrier turn-off in the frequency band.

When the U2100 does not have a co-coverage cell, if the network management device determines, according to the engineering parameters and configuration parameters of the UMTS network supported by the base station, that the LTE cell of the same station (geographical co-station/co-RF module) does not support voltage, and the UMTS cell "CSFB Target" of the same station is not fully NULL, it indicates that the UMTS network supported by the base station supports CSFB from the LTE network to the UMTS network (L2U), at this time, the cell "CSFB Target" corresponding to the first frequency band in the U900 or U2100 must not be NULL, that is, the cell corresponding to the first frequency band in the U900 or U2100 supports L2 CSFB 2U, the whole frequency band of U can be used as the second frequency band corresponding to the UMTS supported by the base station, otherwise, the GSM cell "CSFB Target" that the same station does not have to be turned off must not be NULL (for example, csg 900 or G1800 that does not participate in turn off exists), that is, that the GSM cell "CSFB Target" 2U or neighboring cell corresponding to the first frequency band supported by the base station exists, otherwise, replacing the first class frequency band corresponding to the U900 with the frequency points with the same frequency band and the cells with multiple numbers. If the cells corresponding to the first frequency band in the U900 still cannot support L2U CSFB after replacement one by one, the first frequency band corresponding to the original U900 is reserved, the first frequency band corresponding to the U2100 is replaced with frequency points with multiple numbers of cells in the same frequency band, and the cells corresponding to the first frequency band in the U2100 support L2U CSFB after replacement.

And the switching-off priority of the UMTS network supported by the base station corresponding to the second frequency band is that the priority of the high frequency point is greater than that of the low frequency point.

For example, the working frequency bands of the LTE network supported by the base station are 900MHz (or 850MHz) L900/850, that is, the first frequency band, and 1800MHz L1800 (or 2100MHz L2100 or 2600MHz L2600), that is, the second frequency band, then the network management device determines that L900/850 is the first frequency band corresponding to the LTE network supported by the base station, and determines that L1800 (or L2100 or L2600) is the second frequency band corresponding to the LTE network supported by the base station.

In a possible implementation manner, in a scenario where the multiple network systems supported by the base station include a 2G network, a 3G network, and a 4G network, when a working frequency band corresponding to the 4G network supported by the base station includes multiple frequency bands with frequencies greater than a first frequency band, and a frequency corresponding to the first frequency band is less than 1GHz, if a second frequency band of a working frequency band common radio frequency module corresponding to the 2G network supported by the base station exists in the frequency bands with frequencies greater than the first frequency band, and the second frequency band corresponding to the 2G network supported by the base station is a second frequency band, and a third frequency band of a working frequency band common radio frequency module corresponding to the 3G network supported by the base station does not exist in the frequency bands with frequencies greater than the first frequency band, the second frequency band is the first frequency band corresponding to the 4G network supported by the base station, and other frequency bands in the working frequency bands corresponding to the 4G network supported by the base station are the 4G network supported by the base station And the corresponding second-type frequency band. The working frequency band corresponding to the 4G network supported by the base station may include the first frequency band, or may not include the first frequency band.

For example, the working frequency band corresponding to the GSM network supported by the base station has G1800 with a working frequency band common RF module corresponding to the LTE network supported by the base station, and G1800 is a second-class frequency band corresponding to the GSM network supported by the base station, at this time, if L2100 and U2100 do not share a RF module, L1800 is a first-class frequency band corresponding to the LTE network supported by the base station (L1800 symbol off), and L2100 and/or L2600 in the working frequency band corresponding to the LTE network supported by the base station is a second-class frequency band corresponding to the LTE network supported by the base station. The turn-off priority of the second frequency band corresponding to the LTE network supported by the base station is as follows: single mode high frequency (L2600) > single mode low frequency (L2100) > common mode L1800.

In a possible implementation manner, in a scenario where the plurality of network systems supported by the base station include a 2G network, a 3G network, and a 4G network, when an operating frequency band corresponding to the 4G network supported by the base station includes a plurality of frequency bands whose frequencies are greater than a first frequency band, and a frequency corresponding to the first frequency band is less than 1GHz, if a second frequency band of an operating frequency band common radio frequency module corresponding to the 2G network supported by the base station exists in the frequency bands whose frequencies are greater than the first frequency band, and the second frequency band corresponding to the 2G network supported by the base station is the second frequency band, and a third frequency band of an operating frequency band common radio frequency module corresponding to the 3G network supported by the base station exists in the frequency bands whose frequencies are greater than the first frequency band, and the third frequency band corresponding to the 4G network supported by the base station satisfies continuous coverage, the third frequency band is the first frequency band corresponding to the 4G network supported by the base station, and the other frequency bands in the working frequency bands corresponding to the 4G network supported by the base station are second-class frequency bands corresponding to the 4G network supported by the base station.

Further, the second frequency band is an 1800MHz frequency band, and the third frequency band includes, but is not limited to, a 1900MHz frequency band or a 2100MHz frequency band.

For example, the working frequency band corresponding to the GSM network supported by the base station has G1800 of a working frequency band common RF module corresponding to the LTE network supported by the base station, and G1800 is a second class frequency band corresponding to the GSM network supported by the base station, if L2100 and U2100 share an RF module, when L2100 meets continuous coverage, L2100 is a first class frequency band corresponding to the LTE network supported by the base station, and L2100 is a second class frequency band corresponding to the LTE network supported by the base station (i.e. L1800 is turned off, and L2100 is reserved), where the turn-off priority of the second class frequency band corresponding to the LTE network supported by the base station is: l2600> L1800> 2100. Under the scene that the L2100 does not satisfy continuous coverage, the first frequency band and the second frequency band corresponding to the LTE network supported by the base station are the same as the first frequency band and the second frequency band corresponding to the LTE network supported by the base station under the scene that the L2100 and the U2100 do not share the RF module. The network management equipment can count the number of times of successful inter-station co-frequency switching and the number of times of successful inter-station pilot frequency switching of all cells of the L2100 in the station, and if the number of times of successful inter-station co-frequency switching is greater than the number of times of successful inter-station pilot frequency switching, the cell corresponding to the L2100 continuously covers the same frequency.

If the working frequency band corresponding to the GSM network supported by the base station has G1800 of a common RF module with the working frequency band corresponding to the LTE network supported by the base station, and G1800 is the first frequency band corresponding to the GSM network supported by the base station, at the moment, L1800 is the second frequency point corresponding to the LTE network supported by the base station, and the turn-off priority of the second frequency band corresponding to the LTE network supported by the base station is as follows: l2600> L2100> L1800.

And if the working frequency band corresponding to the GSM network supported by the base station does not have the G1800 of the working frequency band common RF module corresponding to the LTE network supported by the base station, L1800 is a second type frequency band corresponding to the LTE network supported by the base station.

In a possible implementation manner, when a cell supporting the voice call service or a cell supporting the circuit domain fallback exists in an operating frequency band corresponding to a 4G network supported by the base station, a cell supporting the voice call service or a cell supporting the circuit domain fallback exists in a first class frequency band corresponding to the 4G network supported by the base station. The frequency of the frequency band corresponding to the cell supporting the voice call service or the cell supporting the circuit domain fallback in the first frequency band corresponding to the 4G network supported by the base station is a frequency band with a lower frequency in the working frequency band corresponding to the 4G network supported by the base station, that is, the frequency band with the lower frequency and supporting the voice call service in the cell supporting the voice call service or the cell supporting the circuit domain fallback in the first frequency band corresponding to the 4G network supported by the base station is preferentially used as the first frequency band for guaranteeing the 4G network voice call service supported by the base station.

If all the cells corresponding to the 4G network supported by the base station do not support the voice call service and do not support the circuit and fallback, the cell supporting the voice call service or the cell supporting the circuit domain fallback may not exist in the first class of frequency band corresponding to the 4G network supported by the base station.

In a possible implementation manner, when the working frequency band corresponding to the 4G network supported by the base station includes a plurality of frequency bands whose frequencies are greater than a first frequency band, and the frequency corresponding to the first frequency band is less than 1GHz, if there is no fourth frequency band having the same frequency as the working frequency band corresponding to the 2G network supported by the base station in the frequency bands whose frequencies are greater than the first frequency band, the first frequency band corresponding to the 4G network supported by the base station is a frequency band with the lowest frequency in the working frequency bands corresponding to the 4G network supported by the base station, and the other frequency bands are second frequency bands corresponding to the 4G network supported by the base station. The working frequency band corresponding to the 4G network supported by the base station may include the first frequency band, or may not include the first frequency band.

For example, the L900/850 does not exist in the working frequency band corresponding to the LTE network supported by the base station, but when the working frequency band exists in the L2100 or above, the L2100 is the first frequency band corresponding to the 4G network supported by the base station, wherein the turn-off priority of the second frequency band corresponding to the 4G network supported by the base station is proportional to the frequency of the frequency band.

In a possible implementation manner, in step S203, the network management device controls the base station to shut down the second type frequency band by sending an indication message for shutting down the second type frequency band to the base station.
