The network management system includes a network management device 110 and at least one base station 120 , and the base station 120 supports multiple networks. standard. The network management device 110 is mainly used to manage and maintain the at least one base station 120. For example, the network management device 110 can reset the base station 120, check the running status of the base station 120, or monitor the base station. The operating state of the base station 110 is optimized, and the base station 110 is optimized. The network management device 110 may specifically be a server.

The base station 120 is a radio transceiver station used for information transfer between the mobile communication switching center and the user equipment, and may specifically be an evolved base station (evolutional node B, eNB), a macro base station, or a micro base station (also referred to as "evolutional node B"). "Small base station"), pico base station, access point (AP) or transmission point (TP), etc., it can also be a base station in a future network, such as a base station in a 5G network.

Further, the networks of multiple standards supported by the base station 120 include, but are not limited to, two or more of the following network standards: a second-generation (2nd-Generation wireless telephone technology, 2G) network, a third-generation mobile Communication technology (3rd-Generation wireless telephone technology, 3G) network, fourth-generation mobile communication technology (4th-Generation wireless telephone technology, 4G) network and fifth-generation mobile communication technology (5th-Generation wireless telephone technology, 5G) network, etc. Wait. For example, global system of mobile communication (GSM) network, code division multiple access (CDMA) network, wideband code division multiple access (WCDMA) network, universal mobile communication system ( universal mobile telecommunications system, UMTS), long term evolution (long term evolution, LTE) network, etc.

The present application provides a multi-standard network control method, which is applied to the network management device shown in FIG. 1 . As shown in FIG. 2 , for any standard network supported by the base station managed by the network management device, the network management device executes The following steps:

S201: Acquire engineering parameters and configuration parameters of each cell in the base station managed by the network management device;

Wherein, the multiple network standards supported by the base station include, but are not limited to, two or more of the following network standards: 2G network, 3G network, 4G network, and 5G network. The engineering parameters of the base station include but are not limited to parameters such as azimuth, downtilt, longitude (longitude), latitude (latitude), identification (ID) of the base station, and 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 the cell of the base station supports voice over long-term evolution (voice over long-term evolution, VoLTE), and whether the cell of the base station supports narrowband Networking (narrow band internet of things, NB-IoT) service, whether the cell of the base station is a multi-radio remote unit (Radio Remote Unit, RRU) cell, whether the cell of the base station supports circuit switched fallback (CSFB), Whether the cell of the base station is a frequency point of CSFB or a neighboring cell, whether the cell of the base station supports voice over long-term evolution (VoLTE) and co-coverage parameters, etc.

S202: Determine the first type of frequency band and the second type of frequency band from the multiple working frequency bands corresponding to the standard network according to the engineering parameters and configuration parameters of the cell supporting the standard network, wherein the cell corresponding to the first type of frequency band satisfies Continuous coverage, the proportion of terminal equipment supporting the first type of frequency band in the cell corresponding to the second type of frequency band is greater than the set value, and the first type of frequency band satisfies the interoperability between networks of this standard and other standard networks ;

Wherein, if the number of successful intra-frequency handovers between the cells corresponding to the first type of frequency band is greater than the number of successful inter-frequency handovers of the cells corresponding to the first type of frequency band, the cell corresponding to the first type of frequency band satisfies continuous coverage . The first type of frequency band satisfies the interoperation between networks of this standard and other standard networks, including the interoperation of data services that occurs when data services are switched between networks (for example, user equipment using data services is connected between 4G networks and 2G/3G networks. During inter-network handover, the interoperability of data services occurs in order to ensure the continuity of data services), and the interoperability of voice services occurs during inter-network handover of voice services (for example, the voice services of 4G networks fall back to 2G/3G networks).

The proportion of terminal equipment supporting the first type of frequency band in the cell corresponding to the second type of frequency band can be determined by the number of terminal equipment supporting the first type of frequency band in the cell corresponding to the second type of frequency band, and the number of the terminal equipment supporting the first type of frequency band. It is expressed as a ratio of the total number of terminal devices in the second type of frequency band, and the set value may be 90%. Specifically, the network management device can identify the proportion of the terminal equipment in the cell supporting each frequency band through the average number and total number of users in each frequency band in the cell dedicated channel (dedicated channel, DCH) state, so as to determine the cell corresponding to the second type of frequency band The proportion of terminal equipment that supports the first type of frequency band. For example, for a scenario where the UMTS network includes the 900MHz frequency band U900 and the 2100MHz frequency band U2100, the terminal penetration rate of the U2100 cell = VS.CellDCHUEs.Band8/VS.CellDCHUEs.BandTotal, where VS.CellDCHUEs.Band8 indicates that the cell is in the CELL_DCH state and supports Band8 The average number of users, VS.CellDCHUEs.BandTotal indicates the total number of users in the cell in the CELL_DCH state supporting each frequency band.

S203: Control the base station to reserve the first type of frequency band and turn off the second type of 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 engineering parameters of the base station and configuration parameters of the base station from the configuration file. Due to the existence of separate master sites (physical base stations) in the existing communication network, different logical base station configuration files in such sites are independent of each other, but cells in different logical base stations may share radio frequency (RF) modules. Therefore, it is necessary to identify the scenario in which the cells in the logical base station share the radio frequency module, establish the relationship between the site and the logical base station, and then establish the mapping relationship between the logical cell and the radio frequency module, so that the network management device can obtain the base station from the base station. In the configuration file, the actual base station corresponding to each logical cell is determined.

In the specific implementation, the network management device identifies the name of the base station, the identification of the base station, the identification of each cell of the base station, and the cabinet frame slot number of the radio frequency module corresponding to the cell from the obtained base station configuration file, and establishes network cells and radio frequency modules of different standards. The mapping relationship between the number of the cabinet frame and the slot number is used to determine whether the different network cells are physically co-sited and co-located with RF modules, so as to obtain 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. Read the eNodeB information from the base station configuration file <eNodeBFunction> (eNodeB function) element, including the eNodeB name (eNodeBFunctionName) and the eNodeB identifier (eNodeBId);

2. Read the cell information of the site from the <cell> (cell) element of the base station configuration file, including the local cell identifier (LocalCellId), cell identifier (CellId), cell duplex mode (FddTddInd), NB-IoT cell indication (NbCellFlag) ), cell bandwidth (DlBandWidth), confirm the specific working mode of each cell of LTE;

3. From the base station configuration file <eUCellSectorEqm> (cell sector equipment) element, read the correspondence between each LTE cell and sector equipment (SECTOREQMID) according to the local cell identifier (LocalCellId);

4. Obtain the cabinet frame slot number of the RF module from the base station configuration file: a. For the configuration mode in which ANTCFGMODE (antenna configuration mode) is ANTENNAPORT (antenna port), read each element from the base station configuration file <SECTOREQM> (sector device) Sector device (SECTOREQMID) transmit antenna port (ANTTYPE equal to 2 or 3) corresponding RF module cabinet slot number; b. For ANTCFGMODE (antenna configuration mode) as BEAM (beam) configuration mode, RRUCN (RRU cabinet number), RRUSRN (RRU frame number) and RRUSN (RRU slot number) respectively indicate the cabinet frame slot number corresponding to the RF module;

5. Establish a mapping relationship 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 the mapping relationship between network cells of other standards and the RF module, which is similar to the above-mentioned method for establishing the mapping relationship between the LTE network cell and the RF module. Refer to the description of the method for establishing the mapping relationship between the LTE network cell and the RF module. It is not repeated here.

Further, the network management device can also use the base station configuration file to determine whether the cells corresponding to the networks of different standards are macro cells, which can be represented by the parameter "Is Macro". Specifically, for a 2G network (such as a GSM network), if the base station is set outdoors, the default is a macro (Macro) cell, and the "Is Macro" parameter of the cell is "Yes"; for a 3G network (such as a UMTS network), If the maximum transmit power of the cell is MaxTxPower ≥ 10w, the cell is a macro cell, and the parameter "Is Macro" corresponding to the cell is "Yes"; for 4G networks (such as LTE networks), through the cell macro and micro attribute command "DSPCELLCSPCSTATUS" The feedback result is to determine whether the cell is a macro cell. The feedback result is MACRO (representing a macro cell), MICRO (representing a micro cell) or NA (representing an invalid value). When the feedback result is MACRO, the parameter corresponding to the cell "IsMacro " is "Yes", when the feedback result is other values except MACRO, the parameter "Is Macro" corresponding to the cell is "No".

The network management device can also determine whether the cells corresponding to the networks of different standards are indoor cells through the base station configuration file, which can be represented by the parameter "Is Lampsite". Specifically, for a 2G network, the parameter "Is Lampsite" of a cell is empty and can be represented by "NULL"; for a 3G network (such as a UMTS network), if the cell is configured with a sector equipment group ULOCELLSECEQMGRP, the cell is an indoor cell, At this time, the parameter "Is Lampsite" corresponding to the cell is "Yes"; for a 4G network (such as an LTE network), if the cell is configured with the cell sector equipment group EuSectorEqmGroup, and the cell sector equipment EUCELLSECTOREQM is not configured, the cell is an indoor cell , and the parameter "Is Lampsite" corresponding to the cell is "No".

For a 4G network (such as an LTE network), the network management device can also determine whether the cell supports the NB service through the base station configuration file, which can be represented by the parameter "Support NB". Specifically, the network management device determines whether the cell supports the NB service by checking the parameter RB reservation mode RbRsvMode that commands the cell RB reservation configuration CELLRBRESERVE. That is, the NB service is supported, and the parameter "Support NB" corresponding to the cell is "Yes" at this time.

The network management device may also use the base station configuration file to determine whether cells corresponding to networks of different standards support multiple RRUs sharing a cell, which may be represented by a parameter "Support SNF". Specifically, for a 4G network (such as an LTE network), if the multi-RRU co-cell indication Cell.MultiRruCellFlag in the base station configuration file is configured as BOOLEAN_TRUE, and the multi-RRU co-cell mode Cell.MultiRruCellMode in the base station configuration file is configured as SFN, or configured as MPRU_AGGREGATION (multi-MPRU aggregated cell), the cell supports multi-RRU co-cell, and the parameter "Support SFN" corresponding to the cell is "Yes" at this time.

For a 4G network (such as an LTE network), the network management device can also determine whether the cell supports a voice service (VoLTE service) through the base station configuration file, which can be represented by the parameter "Support VoLTE". Specifically, the network management device checks the parameter EUTRAN support VoIP capability switch EutranVoipSupportSwitch in the eNodeB-level algorithm switch by checking the command eNodeB-level algorithm switch ENODEBALGOSWITCH, and if it is set to "ON", then all LTE cells under the eNodeB support Volte services.

For a 4G network (such as an LTE network), the network management device can also determine whether the cell supports CSFB from the 4G network to the 3G network through the base station configuration file, which can be represented by the parameter "Support L2U CSFB". Specifically, if eNodeB level and Cell level UtranCsfbSwitch=OFF, the cell does not support CSFB from 4G network to 3G network, and the parameter "Support L2U CSFB" corresponding to the cell at this time is "No", if the parameter field does not exist, Then the cell does not support CSFB from 4G network to 3G network, and the parameter "Support L2U CSFB" corresponding to the cell is "OFF"; if "BlindHoSwitch" in the eNodeB or Cell-level HoModeSwitch is not all 1, the cell supports switching from 4G to 3G. From the network to the CSFB of the 3G network, the parameter "Support L2U CSFB" corresponding to the cell is the corresponding CSFB mode "Non Blind" (non-blind handover). CSFB from 4G network to 3G network is not supported. At this time, the parameter "Support L2U CSFB" corresponding to the cell is the CSFB mode "Redirection" (redirection), "PS HO" (packet switching (packet switching) corresponding to the actual value of "CsfbHoPolicyCfg"). switch, PS) handover) or "CCOHO" (cell change order (cell change order, CCO) handover).

For a 4G network (such as an LTE network), the network management device can also determine whether the cell supports CSFB from the 4G network to the 2G network through the base station configuration file, which can be represented by the parameter "Support L2G CSFB". Specifically, if the eNodeB and Cell-level UtranCsfbSwitch=OFF, the cell does not support CSFB from 4G network to 2G network. At this time, the parameter "Support L2G CSFB" corresponding to the cell is "No". If the parameter field does not exist, the cell CSFB from 4G network to 2G network is not supported, and 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 , the parameter "Support L2G CSFB" corresponding to the cell is the corresponding CSFB mode "Non Blind" (non-blind handover); if "BlindHoSwitch" in eNodeB and Cell-level HoModeSwitch are both 1, the cell supports switching from 4G network to 2G network At this time, the parameter "Support L2G CSFB" corresponding to the cell is the corresponding CSFB mode "Redirection" (redirection) or "PS HO" (PS handover). If "Redirection" or "PS HO" is not included, the cell CSFB from 4G network to 2G network is supported, and the parameter "Support L2G CSFB" corresponding to the cell is "Other" (representing other CSFB modes).

For the 3G network, the network management device can also determine whether the cell is a frequency point or a neighboring cell of the CSFB of the 4G network through the base station configuration file, which can be represented by the 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 share the radio frequency module 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 4G network cell If the parameter "Support L2U CSFB" of the medium cell is not "No" or "Non Blind", then further according to the handover method between the 4G network and the 3G network, determine the parameter "CSFB Target" corresponding to the 3G network cell, otherwise the parameters corresponding to the cell "Support L2U CSFB" is NULL. Among them, if blind handover is adopted between the 4G network and the 3G network, the 3G network cell is the frequency point or adjacent cell of the 4G network CSFB, and the parameter "CSFB Target" corresponding to the cell is CSFB BlindHO. The parameter "CSFB Target" is NULL; if blind redirection is used between the 4G network and the 3G network, the 3G network cell is the frequency point or adjacent cell of the 4G network CSFB, and the parameter "CSFB Target" corresponding to the cell is CSFB Freq. If it does not exist, the parameter "CSFBTarget" corresponding to the cell is NULL.

For the 2G network, the network management device can also determine whether the cell is a frequency point or a neighboring cell of the CSFB of the 4G network through the base station configuration file. Specifically, if the network management device determines that the 2G network cell and the 4G network cell are geographically co-located or share the radio frequency module 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 4G network cell If the parameter "Support L2G CSFB" of the cell is not "No" or "Non Blind", the parameter "CSFB Target" corresponding to the cell of the 2G network is further determined according to the handover method between the 4G network and the 2G network, otherwise the parameter "CSFB Target" corresponding to the cell is determined.

Among them, if blind handover is used 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, fill in NULL; c. If the blind switch is used between the 4G network and the 2G network Orientation, 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 correspondence tables, and in step S201, the network management device may establish from the network management device In the above-mentioned mapping relationship stored and stored, the engineering parameters and configuration parameters of each cell in the base station managed by the network management device are obtained. For example, the network management device can save the mapping relationship between the cell and the RF radio frequency module and the mapping relationship between the cell and the cell configuration parameters. , or, the network management device may save a mapping relationship between a cell and cell engineering parameters and configuration parameters.

Further, in step S203, the network management device turns off the second type of frequency band according to the priority of switching off the second type of frequency band from high to low; The interruption priority is proportional to the frequency of the second type of frequency band.

In a specific embodiment, since a macro cell consumes more power than an indoor cell, in order to further improve the energy saving effect, the cell corresponding to the second type of frequency band determined by the network management device is a macro cell.

In a specific embodiment, when there are multiple remote radio frequency unit RRUs sharing cells in the cells corresponding to the second type of frequency bands, there are multiple RRUs sharing cells in the cells corresponding to the first type of frequency bands, so as to ensure consistent network coverage, This further ensures the network performance after the second type of frequency band is turned off.

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

a. The frequency of the first type of frequency band corresponding to the 2G network supported by the base station is lower than the frequency of the second type of frequency band, and there is no circuit domain fallback of the 4G network in the second type of frequency band corresponding to the 2G network supported by the base station frequency or neighboring cells; or,

b. The frequency of the first type of frequency band corresponding to the 2G network supported by the base station is lower than the frequency of the second type of frequency band corresponding to the 2G network supported by the base station, and the frequency of the first type of frequency band corresponding to the 2G network supported by the base station is in the There is a frequency point or neighboring cell where the circuit domain fallback of the 4G network exists; or,

c. The frequency of the first type of frequency band corresponding to the 2G network supported by the base station is lower than the frequency of the second type of frequency band corresponding to the 2G network supported by the base station, and the frequency of the first type of frequency band corresponding to the 2G network supported by the base station is not There is a frequency point or adjacent cell where the circuit domain of the 4G network falls back, and there is no frequency point or adjacent cell where the circuit domain falls back of the 4G network in the second type frequency band corresponding to the 2G network supported by the base station, but the 3G network supported by the base station does not exist. In the first type of frequency band corresponding to the network, there is a frequency point or neighboring cell of the frequency band where the circuit domain of the 4G network falls back.

For example, for the GSM network supported by the base station, the GMS network includes the 1800MHz frequency band G1800 and the 900MHz frequency band G900, the first type of frequency band corresponding to the GSM network is G900, and the second type of frequency band corresponding to the GSM network is G1800, wherein, There is no CSFB frequency point or adjacent cell of the 4G network in the G1800; or, the first type of frequency band corresponding to the GSM network is G900, and the second type of frequency band corresponding to the GSM network is G1800, wherein there is a 4G network in G900. The frequency point or adjacent cell of the CSFB; or, the first type of frequency band corresponding to the GSM network is G900, and the second type of frequency band corresponding to the GSM network is G1800, wherein neither G900 nor G1800 has CSFB of 4G network The frequency point or adjacent cell of the 4G network exists in the first type of frequency band corresponding to the UMTS network supported by the base station.

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

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

Further, when the multiple network formats 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 voice call services, the 3G network supported by the base station supports the circuit of the 4G network. domain fallback, then there is a frequency point or neighboring cell of the circuit domain fallback of the 4G network in the first frequency band corresponding to the 3G network supported by the base station; or, there is a 4G network in the first type frequency band corresponding to the 2G network supported by the base station. The frequency point or adjacent cell where the circuit domain of the network falls back.

For example, for the UMTS network supported by the base station, the UMTS network includes a 900MHz frequency band U900 and a 2100MHz frequency band U2100. The network management device determines, according to the engineering parameters and configuration parameters of the UMTS network supported by the base station, the frequency point with the largest number of cells in U900 and U2100 as the first type of frequency band corresponding to the UMTS network supported by the base station, if the U2100 The proportion of terminal equipment supporting U900 in the corresponding cell is less than 90%, then U2100 cannot be used as the second type of frequency band corresponding to the UMTS network supported by the base station. The other frequency points outside the class frequency band are determined as the second class 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 shutdown within the frequency band.

If U900 or U2100 does not exist, other frequency points in U900 and U2100 except the first type frequency band corresponding to the UMTS network supported by the base station are determined as the second type frequency band corresponding to the UMTS network supported by the base station, that is, all The operating frequency band corresponding to the UMTS network supported by the base station can only perform carrier shutdown within the frequency band; if the U900 or U2100 does not exist, and there is only one frequency point in the frequency band, the UMTS network supported by the base station cannot perform energy saving optimization.

Further, when there is a co-covered cell of U2100 in U900, 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 same site (geographic co-site/co-RF module) LTE cell does not support Volte, and the parameter "CSFB Target" of the UMTS cell at the same site is not all NULL, indicating that the UMTS network supported by the base station supports CSFB from the LTE network to the UMTS network (L2U). At this time, the first type of frequency band in U900 or U2100 corresponds to The parameter "CSFB Target" of the cell must be non-NULL, that is, the cell corresponding to the first type of frequency band in the U900 or U2100 supports L2UCSFB, and the entire frequency band of the U2100 can be used as the second type of frequency band corresponding to the UMTS supported by the base station, otherwise, The parameter "CSFB Target" of a GSM cell in the same station that is not turned off must be non-NULL (such as G900, or there is a G1800 that does not participate in the shutdown), that is, there is a first-class frequency band corresponding to the GSM network supported by the base station. The frequency point of the L2U CSFB or the adjacent cell, otherwise, the first type of frequency band corresponding to the U900 is replaced with a frequency point with more cells in the same frequency band. If the cells corresponding to the first type of frequency bands in the U900 still cannot support L2U CSFB after being replaced one by one, the working frequency band corresponding to the UMTS network supported by the base station can only perform carrier shutdown within the frequency band.

When the U2100's co-covered cell does not exist in the U900, 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 co-site (geographic co-site/co-RF module) LTE cell does not support Volte, And the UMTS cell "CSFB Target" of the same site is not all NULL, indicating that the UMTS network supported by the base station supports CSFB from the LTE network to the UMTS network (L2U). Target" must be non-NULL, that is, the cell corresponding to the first type of frequency band in the U900 or U2100 supports L2U CSFB, and the entire frequency band of U2100 can be used as the second type of frequency band corresponding to the UMTS supported by the base station. The "CSFB Target" of the GSM cell that is turned off must be non-NULL (for example, G900, or there is a G1800 that does not participate in the shutdown), that is, there is a frequency point or neighboring L2U CSFB in the first type of frequency band corresponding to the GSM network supported by the base station. Otherwise, replace the first type of frequency band corresponding to the U900 with a frequency point with more cells in the same frequency band. If the cells corresponding to the first type of frequency band in the U900 still cannot support L2U CSFB after the replacement one by one, the first type of frequency band corresponding to the original U900 is retained, and the first type of frequency band corresponding to the U2100 is replaced with the number of cells in the same frequency band The next most frequency point, until after the replacement, the cell corresponding to the first type of frequency band in the U2100 supports L2U CSFB.

Wherein, the shutdown priority of the UMTS network supported by the base station corresponding to the second type of frequency band is that the priority of the high frequency point is higher than the priority of the low frequency point.

In a possible implementation, if the working frequency bands corresponding to the 4G network supported by the base station are the first frequency band and the second frequency band, the frequency corresponding to the first frequency band is less than 1 GHz, and the frequency of the second frequency band is greater than the frequency of the first frequency band. The frequency of a frequency band, the first frequency band is the first type of frequency band corresponding to the 4G network supported by the base station, and the second frequency band is the second type of frequency band corresponding to the 4G network supported by the base station.

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

In a possible implementation, in a scenario where the multiple network standards supported by the base station include 2G networks, 3G networks, and 4G networks, when the working frequency band corresponding to the 4G network supported by the base station includes multiple frequencies greater than the first frequency band When the frequency corresponding to the first frequency band is less than 1GHz, if there is a second frequency band of the same radio frequency module in the working frequency band corresponding to the 2G network supported by the base station in the frequency bands with the frequency greater than the first frequency band, and The second type of frequency band corresponding to the 2G network supported by the base station is the second type of frequency band, and there is no common radio frequency module in the working frequency band corresponding to the 3G network supported by the base station in the frequency bands with frequencies greater than the first frequency band. The third frequency band, the second frequency band is the first type of frequency band corresponding to the 4G network supported by the base station, and the other frequency bands in the working frequency band corresponding to the 4G network supported by the base station are those corresponding to the 4G network supported by the base station. The second type of frequency band. Wherein, 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 a G1800 that shares the same RF module with the working frequency band corresponding to the LTE network supported by the base station, and the G1800 is the second type frequency band corresponding to the GSM network supported by the base station. If L2100 and U2100 do not share an RF module, L1800 is the first type of frequency band corresponding to the LTE network supported by the base station (the L1800 symbol is turned off), and the L2100 and/or L2100 in the working frequency band corresponding to the LTE network supported by the base station The L2600 is the second type of frequency corresponding to the LTE network supported by the base station. Wherein, the shutdown priority of the second type of frequency band corresponding to the LTE network supported by the base station is: single-mode high frequency point (L2600) > single-mode low frequency point (L2100) > common mode L1800.

In a possible implementation, in a scenario where the multiple network standards supported by the base station include 2G networks, 3G networks, and 4G networks, when the working frequency band corresponding to the 4G network supported by the base station includes multiple frequencies greater than the first frequency band When the frequency corresponding to the first frequency band is less than 1GHz, if there is a second frequency band of the same radio frequency module in the working frequency band corresponding to the 2G network supported by the base station in the frequency bands with the frequency greater than the first frequency band, and The second type of frequency band corresponding to the 2G network supported by the base station is the second type of frequency band, and the plurality of frequency bands with frequencies greater than the first frequency band have a third frequency band that shares the same radio frequency module with the working frequency band corresponding to the 3G network supported by the base station. 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 type frequency band corresponding to the 4G network supported by the base station, and the 4G network supported by the base station corresponds to The other frequency bands in the working frequency band are the second type frequency bands corresponding to the 4G network supported by the base station.

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

For example, the working frequency band corresponding to the GSM network supported by the base station has a G1800 with the same RF module as the working frequency band corresponding to the LTE network supported by the base station, and the G1800 is the second type frequency band corresponding to the GSM network supported by the base station. L2100 and U2100 share RF modules. When L2100 satisfies continuous coverage, L2100 is the first type of frequency band corresponding to the LTE network supported by the base station, and L2100 is the second type of frequency band corresponding to the LTE network supported by the base station. L1800, keep L2100), wherein the second type of frequency band shutdown priority corresponding to the LTE network supported by the base station is: L2600>L1800>2100. In the scenario where the L2100 does not meet continuous coverage, the first type of frequency band and the second type of frequency band corresponding to the LTE network supported by the base station are the same as the first type of frequency band corresponding to the LTE network supported by the base station in the scenario where the L2100 and U2100 do not share RF modules. The first type of frequency band and the second type of frequency band are the same. Wherein, the network management device can count the number of successful inter-site intra-frequency handovers and the number of successful inter-site inter-frequency handovers of all cells of the L2100 in the station. If the number of successful intra-site intra-frequency handovers > the number of successful inter- The corresponding cell has continuous coverage on the same frequency.

If the working frequency band corresponding to the GSM network supported by the base station has a G1800 with the same RF module as the working frequency band corresponding to the LTE network supported by the base station, and the G1800 is the first type of frequency band corresponding to the GSM network supported by the base station, this When L1800 is the second type of frequency point corresponding to the LTE network supported by the base station, the second type of frequency band shutdown priority corresponding to the LTE network supported by the base station is: L2600>L2100>L1800.

If the working frequency band corresponding to the GSM network supported by the base station does not exist in the G1800 sharing the RF module with the working frequency band corresponding to the LTE network supported by the base station, L1800 is the second type frequency band corresponding to the LTE network supported by the base station.

In a possible implementation manner, when there is a cell supporting voice call service or a cell supporting circuit domain fallback in the working frequency band corresponding to the 4G network supported by the base station, the first type of frequency band corresponding to the 4G network supported by the base station is included. There are cells that support voice call services or cells that support CS fallback. Wherein, 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 type frequency band corresponding to the 4G network supported by the base station is the frequency of the frequency band corresponding to the working frequency band corresponding to the 4G network supported by the base station. The low frequency band, that is, the cell that supports the voice call service in the first type of frequency band corresponding to the 4G network supported by the base station or the frequency band that supports the circuit domain fallback and has a lower frequency is given priority to guarantee the 4G network voice call service supported by the base station. the first category of frequency bands.

If all cells corresponding to the 4G network supported by the base station do not support the voice call service and do not support circuit and fallback, there may be no cells supporting the voice call service in the first type of frequency band corresponding to the 4G network supported by the base station or Cells that support circuit domain fallback.

The frequency band with the lowest frequency among the frequency bands, and the other frequency bands are the second type frequency bands corresponding to the 4G network supported by the base station. Wherein, 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, there is no L900/850 in the working frequency band corresponding to the LTE network supported by the base station, but when there is an L2100 and above frequency bands, L2100 is the first type of frequency band corresponding to the 4G network supported by the base station, wherein, The shutdown priority of the second type of frequency band corresponding to the 4G network supported by the base station is proportional to the frequency of the frequency band.
