[0043] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0044] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0045] The terms “first” and “second” in this disclosure and its accompanying drawings are used to distinguish different objects or to distinguish different treatments of the same object, rather than to describe a particular order of objects.

[0046] Furthermore, the terms “comprising” and “having”, and any variations thereof, used in the description of this disclosure are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that comprises a series of steps or units is not limited to the steps or units listed, but may also include other steps or units not listed, or may include other steps or units inherent to such process, method, product, or apparatus.

[0047] It should be noted that in some embodiments of this disclosure, the words "exemplarily" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplarily" or "for example" in some embodiments of this disclosure should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of words such as "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner.

[0048] In the description of this disclosure, unless otherwise stated, "multiple" means two or more.

[0049] The following explains some concepts involved in a cell handover method, apparatus, network device, and storage medium provided in some embodiments of this disclosure.

[0050] Lightweight terminals: These are lightweight 5G terminal technologies defined by the 3rd generation partnership project (3GPP) in Release 17 (R17). The full name is reduced capability terminal, or simply redcap terminal. It further simplifies 5th generation mobile communication (5G) technology, for example, reducing the bandwidth of the 5G enhanced mobile broadband (eMBB) band from 100MHz to 20MHz, reducing the number of transceiver antennas from four to two or one, and lowering the modulation method to 64 quadrature amplitude modulation (QAM). This achieves lower terminal costs and lower power consumption, contributing to the large-scale adoption of 5G industry terminals.

[0051] Considering that in the initial stage of lightweight terminal network deployment, lightweight terminal functions are not supported by upgrading the entire network to version R17, many networks do not have lightweight terminal capabilities without the upgrade. Long term evolution (LTE), 5G new radio (NR) cells and 5G lightweight terminal cells coexist in the existing network.

[0052] According to 3GPP protocols, lightweight terminals should not access networks that do not support them. In scenarios where multi-mode lightweight terminals handover from LTE to 5G, the LTE network cannot recognize the lightweight terminal and cannot determine whether neighboring cells support it, potentially leading to a handover failure as the terminal may switch to a non-lightweight terminal cell. Similarly, in scenarios where single-mode lightweight terminals handover from LTE to 5G, the 5G network does not support them, potentially causing handover failure when switching to a 5G cell.

[0053] In related technologies, when the terminal type is a lightweight terminal, the low-capability network cannot recognize the lightweight terminal and may instruct the terminal to switch to a cell that does not support lightweight terminals, thus causing the handover to fail.

[0054] Based on this, some embodiments of this disclosure provide a cell handover method, apparatus, access network device, and storage medium. In response to the access of a first access terminal, the first access network device sends the terminal identifier of the first access terminal to a network management device. The network management device can determine the terminal type of the first access terminal based on the terminal identifier. If the terminal type of the first access terminal includes a lightweight terminal, the network management device sends first indication information to the first access network device. Since the first indication information is used to instruct cell handover to be performed on the first access terminal based on a target cell list, and the target cell list is a list of cells that support the terminal type of the first access terminal, the first access network device can perform cell handover on the first access terminal based on the first indication information, accurately switching the first access terminal to a cell that supports the terminal type of the first access terminal.

[0055] This disclosure provides a cell handover method, apparatus, access network device, and storage medium in some embodiments that can be applied to a cell handover system. As shown in FIG1, the cell handover system includes a terminal 101, an access network device 102, and a network management device 103. Typically, in practical applications, the connection between the above-mentioned devices can be a wireless connection. To facilitate a clear and intuitive representation of the connection relationship between the devices, solid lines are used in FIG1.

[0056] For example, in response to the access of terminal 101, access network device 102 can send the terminal identifier of terminal 101 to network management device 103, and after receiving the first instruction information sent by network management device 103, perform cell handover for terminal 101 based on the target cell list.

[0057] Network management device 103 can obtain the terminal identifier of terminal 101 reported by access network device 102, and then determine the terminal type of terminal 101 based on the terminal identifier of terminal 101 and the mapping relationship between terminal identifier and terminal type; in response to the terminal type of terminal 101 including lightweight terminal, it sends first indication information to access network device 102.

[0058] Terminal 101 can access access network device 102 and perform cell handover based on the handover command of access network device 102.

[0059] As shown in Figures 1 and 2, the network management device 103 may include a data storage module 1031, an identification and analysis module 1032, a network management judgment module 1033, and a terminal control module 1034.

[0060] For example, the data storage module 1031 is used to store the capability information of all access network devices within its jurisdiction and the terminal information of terminals connected to the access network devices within its jurisdiction.

[0061] The identification and analysis module 1032 is used to generate a mapping relationship between terminal identifiers and terminal types, and to identify the terminal type corresponding to a terminal identifier based on the mapping relationship.

[0062] The network management judgment module 1033 is used to count the terminal type of the terminal based on the terminal information reported by multiple access network devices.

[0063] The terminal management module 1034 is used to determine different handover strategies based on the terminal type.

[0064] For example, taking the access network device 102 in Figure 1 as a commonly used base station, the hardware structure of the access network device 102 provided in some embodiments of this disclosure is introduced.

[0065] As shown in Figure 3, the base station provided in some embodiments of this disclosure may include a first part 30 and a second part 31. The first part 30 is mainly used for transmitting and receiving radio frequency signals and converting radio frequency signals to baseband signals; the second part 31 is mainly used for baseband processing and controlling the base station. The first part 30 can generally be referred to as a transceiver unit, transceiver, transceiver circuit, or transceiver, etc. The second part 31 is usually the control center of the base station and can generally be referred to as a processing unit.

[0066] The transceiver unit of the first part 30, also known as a transceiver or transceiver device, includes an antenna 301 and a radio frequency (RF) unit 302, or the first part 30 includes the RF unit 302 or a portion thereof. The RF unit is mainly used for RF processing.

[0067] In some embodiments, the devices in the first part 30 used to implement the receiving function can be regarded as receiving units, and the devices in the first part 30 used to implement the transmitting function can be regarded as transmitting units. For example, the first part 30 may include a receiving unit and a transmitting unit. The receiving unit may also be referred to as a receiver, a receiver circuit, or a receiving device, etc., and the transmitting unit may be referred to as a transmitter, a transmitter, or a transmitting circuit, etc.

[0068] The second part 31 may include one or more single boards, or the second part 31 may include one or more chips. Each single board or chip may include at least one processor 311 and at least one memory 312. The processor 311 is used to read and execute programs in the memory 312 to implement baseband processing functions and control the base station. Here, "at least one" includes one or more.

[0069] If the second part 31 includes multiple boards, any two boards can be interconnected to increase processing capacity.

[0070] In some embodiments, multiple boards may share one or more processors 311, or multiple boards may share one or more memories 312. For example, the memory 312 and the processor 311 may be integrated together or set up independently.

[0071] In some embodiments, the first part 30 and the second part 31 may be integrated together or set independently. Furthermore, all functions in the second part 31 may be implemented in a single chip, or some functions may be implemented in one chip while others are implemented in one or more other chips; this disclosure does not limit this.

[0072] The cell handover methods, apparatus, network devices, and storage media provided in some embodiments of this disclosure are applied in cell handover scenarios, especially in scenarios where a terminal hands over from an LTE cell to a lightweight terminal cell.

[0073] When a first access terminal accesses a first access network device, the first access network device can send the terminal identifier of the first access terminal to a network management device. The network management device determines the terminal type of the first access terminal based on the terminal identifier. In response to the fact that the terminal type of the first access terminal includes a lightweight terminal, the network management device sends first indication information to the first access network device. If the terminal type of the first access terminal includes a lightweight terminal, the first access network device performs cell handover for the first access terminal based on the target cell list.

[0074] Based on the cell handover system shown in Figure 1 above, the following describes in detail some embodiments of the cell handover method provided by this disclosure from the perspective of the interaction between various devices in the cell handover system, so as to illustrate the process of the first access network device handing over the cell for the first access terminal based on the instruction information of the network management device.

[0075] As shown in Figure 4, some embodiments of the present disclosure provide a cell handover method that may include steps S401-S406.

[0076] S401. In response to the access of the first access terminal, the first access network device sends the terminal identifier of the first access terminal to the network management device.

[0077] It is understandable that after the first access terminal accesses the first access network device, the first access network device can obtain the terminal identifier of the first access terminal.

[0078] In some embodiments, the terminal identifier of the first access terminal may include International Mobile Equipment Identity (IMEI), International Mobile Subscriber Identification Number (IMSI), Mobile Subscriber International ISDN Number (MSISDN), Integrated Circuit Card Identity (ICCID), etc.

[0079] In some embodiments, an access terminal includes multiple terminal types, and the first access network device can also obtain the terminal type used by the first access terminal when accessing the network.

[0080] In some embodiments, the first access network device may send the above information to the network management device.

[0081] S402. The network management device obtains the terminal identifier of the first access terminal reported by the first access network device.

[0082] For example, the first access terminal is a terminal that accesses the first access network device.

[0083] S403. The network management device determines the terminal type of the first access terminal based on the terminal identifier of the first access terminal and the mapping relationship between the terminal identifier and the terminal type.

[0084] It is understood that this mapping relationship is a mapping relationship stored in the network management device, which includes multiple terminal identifiers and the terminal type corresponding to each of the multiple terminal identifiers.

[0085] In some embodiments, the terminal type of the first access terminal may include one or more of an LTE terminal, an eMBB terminal, and a lightweight terminal.

[0086] In some embodiments of this disclosure, the lightweight terminal is an advanced terminal that cannot be recognized under low-capability networks.

[0087] Understandably, this low-capability network is a lower-level network type compared to the network where the lightweight terminal is located.

[0088] For example, the lightweight terminal can be a 5G redcap terminal that cannot be recognized by a 4G network, and the low-capability network can be a 4G network.

[0089] In some embodiments, the lightweight terminal may also be a 6G terminal that is not recognized by the 5G network.

[0090] Table 1 shows an example of a mapping relationship.

[0091] Table 1

[0092] As shown in Table 1, the terminal is identified by its ICCID, which includes A, B, C, and D. For example, A corresponds to the terminal type "lightweight terminal + LTE", B corresponds to the terminal type "eMBB", C corresponds to the terminal type "lightweight terminal + eMBB + LTE", and D corresponds to the terminal type "lightweight terminal".

[0093] S404. In response to the fact that the terminal type of the first access terminal includes a lightweight terminal, the network management device sends a first instruction message to the first access network device.

[0094] For example, the first indication information is used to instruct the first access terminal to perform cell handover based on the target cell list; the target cell list is a list of cells that support the terminal type of the first access terminal.

[0095] Understandably, this first indication information includes the list of target cells.

[0096] The target cell list includes multiple target cells, each of which supports at least one terminal type for the first access terminal.

[0097] Since the terminal type of the first access terminal includes lightweight terminals, the target cell includes cells that support lightweight terminals.

[0098] The network management device stores the terminal types supported by the corresponding cells of the access network devices within its jurisdiction.

[0099] Furthermore, if the terminal type of the first access terminal includes the lightweight terminal, it indicates that the first access terminal can access the cell of the lightweight terminal. In order to avoid the first access network device being unable to recognize the lightweight terminal and / or unable to know the cell that supports the lightweight terminal, the network management device can send a first instruction information to the first access network device so that the first access network device can perform cell handover for the first access terminal based on the target cell list, for example, handover to a target cell in the target cell list.

[0100] In one implementation, if the terminal type of the first access terminal does not include lightweight terminals, the network management device may not send any indication information to the first access network device. For example, the first access network device may perform cell handover for the first access terminal on its own.

[0101] In another implementation, if the terminal type of the first access terminal is a lightweight terminal, it means that the current serving cell of the first access terminal is a cell that supports lightweight terminals. The first access network device can know the terminal type of the first access terminal and the cell that supports lightweight terminals. At this time, the network management device can also send a second indication information to the first access terminal. The second indication information is used to indicate that no handover control should be initiated for the first access terminal.

[0102] S405. The first access network device receives the first instruction information sent by the network management device.

[0103] S406. The first access network device performs cell handover on the first access terminal based on the target cell list.

[0104] For example, the first access network device can switch the serving cell of the first access terminal to a cell in the target cell list.

[0105] In one implementation, the first access device can set the target cell list as a base station execution condition switching element, and the first access terminal can perform execution condition switching based on the execution condition switching element.

[0106] In some embodiments of this disclosure, the first access network device may also report the network type of the serving cell of the first access terminal to the network management device. After the network management device obtains the cell capability of the serving cell of the first access terminal reported by the first access network device, it may send the first indication information to the first access network device in response to the fact that the terminal type of the first access terminal includes a lightweight terminal and the network type of the serving cell of the first access terminal is a low-capability network.

[0107] For example, when the network management device identifies that the terminal type of the first access terminal includes a 5Gredcap terminal and the serving cell of the first access terminal is a 4G cell, it can send the first indication information to the first access network device so that the first access network device can accurately switch the first access terminal from the 4G network to the 5G network.

[0108] The technical solution provided by the above embodiments can bring at least the following beneficial effects: As can be seen from steps S401-S406, in response to the access of the first access terminal, the first access network device can send the terminal identifier of the first access terminal to the network management device. The network management device can determine the terminal type of the first access terminal based on the terminal identifier of the first access terminal and the mapping relationship between the terminal identifier and the terminal type. In response to the fact that the terminal type of the first access terminal includes a lightweight terminal, the first access network device sends first indication information to the first access network device. Then the first access network device can perform cell handover for the first access terminal based on the target cell list.

[0109] In some embodiments of this disclosure, in response to the access of a first access terminal, a first access network device sends the terminal identifier of the first access terminal to a network management device. The network management device can determine the terminal type of the first access network terminal based on the terminal identifier of the first access terminal. If the terminal type of the first access terminal includes a lightweight terminal, the network management device sends first indication information to the first access network device. Since the first indication information is used to instruct the first access terminal to perform cell handover based on a target cell list, and the target cell list is a list of cells that support the terminal type of the first access terminal, the first access network device can perform cell handover for the first access terminal based on the first indication information, and can accurately switch the first access terminal to a cell that supports the terminal type of the first access terminal.

[0110] As shown in Figures 4 and 5, in some embodiments of this disclosure, the above-mentioned cell handover of the first access terminal based on the target cell list may include steps S501-S504.

[0111] S501, The first access network device receives the first measurement report sent by the first access terminal.

[0112] For example, the first measurement report includes the signal quality of multiple neighboring cells.

[0113] It is understandable that after the first access terminal accesses the first access network device, when a handover needs to be performed, it can perform neighbor cell measurement, obtain the first measurement report, and then send the first measurement report to the first access network device.

[0114] For example, the multiple neighboring cells are the final cells that the first access terminal can measure.

[0115] S502, The first access network device identifies multiple neighboring cells included in the measurement report that overlap with the target cell list.

[0116] It is understandable that the first access network device may not be able to know whether the multiple neighboring cells support lightweight terminals. Therefore, the first access network device can determine the cells that support lightweight terminals from the multiple neighboring cells.

[0117] For example, the first access network device can compare multiple neighboring cells with the target cell list, and the overlapping cells obtained are the cells among the multiple neighboring cells that support lightweight terminals.

[0118] S503. The first access network device determines the first cell whose signal quality meets the preset conditions from the overlapping cells.

[0119] It is understandable that if the signal quality of a cell meets the preset conditions, it means that the signal quality of the cell is relatively good. At this time, the first access network device can determine to switch the first access terminal to the cell.

[0120] The preset condition can be one of the following: the cell with the highest signal strength, or the cell with a signal strength higher than the current serving cell of the first access terminal.

[0121] S504. The first access network device sends a first handover command to the first access terminal.

[0122] For example, the first handover instruction is used to instruct the first access terminal to hand over to the first cell.

[0123] It is understandable that after receiving the first handover instruction, the first access terminal can switch the serving cell to the first cell.

[0124] Based on the list of multiple neighboring cells and target cells in the first measurement report of the first access terminal, the first access network device determines overlapping cells. It can first determine the cells that the first access terminal can connect to and that support the lightweight terminal, and then determine the first cell with better signal quality from the overlapping cells and instruct the first access terminal to hand over to the first cell, which can improve the accuracy of cell handover.

[0125] As shown in Figures 4 and 6, in some embodiments of this disclosure, the above-mentioned cell handover of the first access terminal based on the target cell list may include steps S601-S604.

[0126] S601, The first access network device sends a measurement command to the first access terminal.

[0127] For example, the measurement instruction is used to instruct the first access terminal to measure the cells included in the target cell list.

[0128] Understandably, the measurement instruction includes the list of target cells.

[0129] S602, The first access network device receives the second measurement report sent by the first access terminal.

[0130] Understandably, after receiving the measurement instruction, the first access terminal can measure the cells included in the cell list and then generate a second measurement report.

[0131] The first access terminal may not be able to measure all the cells in the cell list, but can only measure the cells in which the first access terminal can receive signals. Therefore, the cells included in the second measurement report are the overlapping cells between the cells in the cell list and neighboring cells.

[0132] S603, The first access network device determines the second cell based on the second measurement report.

[0133] In some embodiments, the first access network device may determine a second cell whose signal quality meets the aforementioned preset conditions from the cells included in the second measurement report.

[0134] S604. The first access network device sends a second handover command to the first access terminal.

[0135] For example, the second handover instruction is used to instruct the first access terminal to hand over to the second cell.

[0136] It is understood that the second handover instruction includes the identifier of the second cell, and after receiving the second handover instruction, the first access terminal can switch its serving cell to the second cell.

[0137] In steps S601-S604 above, the first access network device instructs the terminal to only measure cells that support lightweight terminals, which can reduce the number of cells measured by the terminal and reduce the terminal's power consumption.

[0138] As shown in Figures 4 and 7, in some embodiments of this disclosure, before the network management device sends the first indication information to the first access network device in response to the first access terminal's terminal type including a lightweight terminal, the cell handover method further includes steps S701-S702.

[0139] S701. When the terminal type of the first access terminal includes a lightweight terminal, the network management device determines the target cell list.

[0140] It is understood that the network management device is used to manage access network devices. Therefore, the network management device stores the capability information of each access network device within its jurisdiction. This capability information includes the terminal types supported by the cell corresponding to each access network device. Then, based on the terminal types supported by the cell corresponding to each access network device, the target cell list is determined.

[0141] In one implementation, the network management device can obtain the cell identifier and supported terminal types of the cells corresponding to each of the multiple access network devices; then determine the cell identifier that supports lightweight terminal types from the cells corresponding to each of the multiple access network devices; and finally generate the target cell list based on the cell identifier that supports lightweight terminal types.

[0142] S702, the network management device generates the first instruction information based on the target cell list.

[0143] It is understandable that when the first access terminal includes multiple terminal types, the first access network device can switch the first access terminal to any cell corresponding to any terminal type. At this time, the network management device can determine the handover priority of the cells corresponding to the multiple terminal types.

[0144] As shown in Figures 7 and 8, in some embodiments of this disclosure, the first indication information further includes a handover policy. The network management device generates the first indication information based on the target cell list, including steps S801-S802.

[0145] S801. When the first access terminal includes multiple terminal types, the network management device determines the handover strategy corresponding to the first access terminal.

[0146] For example, the handover strategy is used to indicate the handover priority of multiple cell types. The handover priority of any cell type among the multiple cell types is used to characterize the priority of handover to that cell type. The cell type of a cell is used to characterize the terminal types supported by that cell.

[0147] It is understandable that the cell type supporting lightweight terminals is a lightweight terminal cell, the cell type supporting LTE terminals is an LTE cell, and the cell type supporting eMBB terminals is an NR cell.

[0148] For example, assuming that the first access terminal is an LTE terminal and a lightweight terminal, the target cell list includes LTE cells and lightweight terminal cells.

[0149] Assuming that the terminal type of the first access terminal includes eMBB terminals and lightweight terminals, then the target cell list includes NR cells and lightweight terminal cells.

[0150] Assuming that the terminal type of the first access terminal includes LTE terminal, eMBB terminal and lightweight terminal, then the target cell list includes NR cell, LTE cell or lightweight terminal cell.

[0151] In one implementation, the network management device may further identify only the cells that support lightweight terminals, and then generate a target cell list based on these cells. Subsequently, the first access network device can perform cell handover for the first access terminal based on the cells that support lightweight terminals.

[0152] In some embodiments of this disclosure, when the first access terminal includes multiple terminal types, the first access terminal can be determined to be a multi-mode terminal.

[0153] For example, the terminal type of the first access terminal can be an eMBB terminal, an LTE terminal, or a lightweight terminal.

[0154] Understandably, the higher the handover priority of a cell type, the higher the priority for the first access network device to switch the terminal to that cell type.

[0155] In one implementation, the network management device can determine the switching policy from the following four strategies.

[0156] Strategy 1: Priority of lightweight terminal cells > Priority of NR cells.

[0157] In some embodiments, when the first access terminal moves from a lightweight terminal cell to an LTE cell, when the first access terminal switches from LTE to 5G, it prioritizes switching to the lightweight terminal cell.

[0158] In some embodiments, when the first access terminal moves from an NR cell to an LTE cell, when the first access terminal switches from LTE to 5G, if the neighboring NR cell is busy, the first access terminal will preferentially switch to a lightweight terminal cell.

[0159] Strategy 2: Priority of NR cells > Priority of lightweight terminal cells.

[0160] In some embodiments, when the first access terminal moves from an NR cell to an LTE cell, when the first access terminal switches from LTE to 5G, if the neighboring NR cell is in an idle state, the first access terminal will preferentially switch to the NR cell.

[0161] Strategy 3: Only switch to cells with lightweight terminals.

[0162] That is, the first access terminal only switches to a lightweight terminal type.

[0163] In some embodiments, when the hardware of the first access terminal supports NR and lightweight terminals, but the software switch does not enable NR capability, when the first access terminal switches from LTE to 5G, it will prioritize switching to the lightweight terminal cell.

[0164] Strategy 4: Handover only to NR cells.

[0165] That is, the first access terminal only switches as an eMBB terminal.

[0166] In some embodiments, when the hardware of the first access terminal supports NR and lightweight terminals, but the software switch does not enable lightweight terminal capabilities, the first access terminal will prioritize switching to the NR cell when switching from LTE to 5G.

[0167] S802, the network management device generates the first indication information based on the handover policy and the target cell list.

[0168] Understandably, the first instruction information includes the handover policy and the target cell list.

[0169] The aforementioned first access network device performs cell handover on the first access terminal based on the target cell list, which may include step S803.

[0170] S803, the first access network device performs cell handover for the first access terminal based on the handover policy and the target cell list.

[0171] For example, this handover strategy is used to indicate the priority of multiple cell types, and the priority of a cell type is used to characterize the priority of handover to that cell type.

[0172] For example, the first access network device can prioritize switching the serving cell of the first access terminal to the highest priority cell type based on the handover strategy.

[0173] It is understandable that when the first access terminal includes multiple terminal types, the network management device sends a handover policy to the first access network device, which can perform cell handover based on the handover policy, thereby improving the accuracy of handover for the first access network device.

[0174] As shown in Figures 4 and 9, in one implementation of some embodiments of this disclosure, the cell handover method further includes steps S901-S903.

[0175] S901, The network management device obtains terminal information of access terminals reported by multiple access network devices.

[0176] For example, the terminal information of any access terminal reported by any one of the multiple access network devices includes: the terminal type used by the access terminal when it accesses the access network device, and the terminal identifier of the access terminal.

[0177] Understandably, when an access terminal connects to an access network device, the access network device can obtain the terminal type used by the access terminal when it connects. At this time, the access network device can report the terminal identifier and the terminal type used by the terminal to the network management device.

[0178] When an access terminal is initially powered on, it can establish a connection with a cell using cell selection methods from various technologies, and perform cell handover during movement using cell handover methods from various technologies. During this process, the access terminal may access multiple cells, and the access network devices corresponding to these multiple cells will report the terminal information of the access terminal.

[0179] In some embodiments, the terminal information may further include the access time and the location information of the terminal.

[0180] In some embodiments, the terminal information may also include parameters such as the number of multiple-in multiple-out (MIMO) layers, modulation scheme, and system bandwidth. Based on these parameters, it can be helpful to determine whether the access terminal is a lightweight terminal.

[0181] S902. The network management device determines at least one terminal type corresponding to the terminal identifier of each access terminal based on the terminal information of the access terminals reported by each of the multiple access network devices.

[0182] It is understandable that the network management device can statistically analyze the terminal information of the access terminals reported by multiple access network devices, obtain the terminal information corresponding to each access terminal, and then obtain at least one terminal type corresponding to the terminal identifier of each access terminal.

[0183] For example, if the first access terminal accesses the network as a lightweight terminal in all cells within the network management jurisdiction, then the first access terminal is determined to be a lightweight terminal; if the first access terminal accesses the network as an LTE terminal, an eMBB terminal, and a lightweight terminal in LTE cells, NR cells, and lightweight terminal cells within the network management jurisdiction, respectively, then the first access terminal is determined to be a multi-mode terminal.

[0184] If the first access terminal completes its first network access in a lightweight terminal cell and has accessed both a lightweight terminal cell and an LTE cell during its movement, then the first access terminal is determined to be a "lightweight terminal + LTE" terminal.

[0185] In one implementation, if the number of reported terminal information entries for the first access terminal is greater than or equal to a threshold, it indicates that the first access terminal has performed multiple cell handovers. In this case, the network management device can determine the terminal type of the access terminal based on the terminal information of the first access terminal.

[0186] S903. The network management device generates a mapping relationship based on at least one terminal type corresponding to the terminal identifier of each access terminal.

[0187] In some embodiments of this disclosure, the network management device determines the terminal type of the access terminal based on the terminal type used by the access terminal when accessing multiple cells. It can statistically integrate the terminal information reported by multiple cells to obtain a more accurate terminal type of the access terminal.

[0188] Some embodiments of this disclosure can divide network management devices, access network devices, etc., into functional modules according to the above method examples. For example, each function can be divided into a separate functional module, or two or more functions can be integrated into one processing module.

[0205] The processing module 1004 is also used to: generate the first indication information based on the handover strategy and the target cell list.

[0206] In some embodiments, the lightweight terminal is an advanced terminal that cannot be recognized under low-capability networks.
