[0002] With the development of communication technologies, in a wireless network, the frequent transmission of common signals such as synchronization signals and system messages will increase the transmission energy consumption of network devices (such as base stations or access points of corresponding cells of base stations, etc.). To reduce the transmission energy consumption of network devices, related technologies have proposed a technology for sending common signals on demand, that is, when a terminal has a transmission requirement, the network device can quickly trigger the transmission of common signals, thereby saving the transmission power consumption of the network device.

[0078] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application.

[0079] In the description of the present application, unless otherwise specified, " / " means "or". For example, A / B may represent A or B. The "and / or" herein is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, "at least one" and "multiple" refer to two or more. The words such as "first" and "second" do not limit the quantity and execution order, and the words such as "first" and "second" do not necessarily limit being different.

[0080] With the development of mobile communication technology from the fifth-generation mobile communication technology (5G) to the sixth-generation mobile communication technology (6G), the bandwidth and number of channels supported by network devices are getting larger and larger, the air interface protocol is becoming more and more complex, and the requirements for device power consumption are also getting higher and higher. In a wireless network, the frequent transmission of public signals will increase the energy consumption of network devices. Especially in the case where 6G networks support more carriers and larger bandwidths, the power overhead of periodically transmitted public signals will further affect network energy efficiency.

[0081] To reduce the energy consumption of wireless networks, related technologies have proposed a technology for transmitting public signals on demand, such as the technology for transmitting synchronization signal / PBCH (SSB) on demand. When this technology is enabled, the public signals of the cell are no longer transmitted periodically, but are transmitted on demand or not transmitted within a certain period of time, thereby saving the transmission power consumption of network devices. That is, when the terminal device has a transmission requirement, the network device can quickly trigger the transmission of public signals.

[0082] However, during the period when the network device does not transmit public signals, it will cause the terminal to be unable to access the cell, thereby reducing the access performance of the terminal.

[0083] To solve the above problems, the present application provides a method for indicating terminal access. By sending a first indication message to the first cell when the first cell does not send a signal, it is indicated to prohibit the second terminal from accessing the first cell corresponding to the first network device within a first preset time period, and / or to reduce the access threshold of the second cell within the first preset time period. In addition, a second indication message is sent to the first terminal to indicate that the first terminal switches or reselects to the third cell before the first network device stops sending the common signal. Thus, it is ensured that the terminals in both the first cell and the second cell can access the cell normally, thereby ensuring the access performance of the terminals.

[0084] A method for indicating terminal access provided by an embodiment of the present application can be applied to a terminal access indication system. Figure 1 The structural schematic diagram of a terminal access indication system is shown. As Figure 1 shown, the terminal access indication system includes: a first network device 11, a second network device 12, a first terminal 13, and a second terminal 14. Among them, the first network device 11 is connected to the second network device 12, the first network device 11 is connected to the first terminal 13, and the second network device 12 is connected to the second terminal 14. The devices can be connected by wire or wirelessly, and the embodiments of the present invention do not limit this.

[0085] The first network device 11 is used to send a first indication message to the second network device 12 to indicate to prohibit the second terminal 14 from accessing the first cell within a first preset time period, and / or to reduce the access threshold of the second cell during the time period when the first network device 11 stops sending the common signal, and to send a second indication message to the first terminal 13 to indicate that the first terminal 13 switches or reselects to the third cell before the first network device 11 stops sending the common signal.

[0086] The second network device 12 is used to respond to the first indication message from the first network device 11 and send a third indication message to the second terminal 14 to prohibit the second terminal 14 from accessing the first cell during the time period when the first network device 11 stops sending the common signal, and / or to reduce the access threshold of the second cell during the time period when the first network device 11 stops sending the common signal.

[0087] The first terminal 13 is used to respond to the second indication message from the first network device 11 and switch or reselect to the third cell before the first network device 11 stops sending the common signal. The second terminal 14 is used to respond to the third indication message from the second network device 12 and prohibit accessing the first cell during the time period when the first network device 11 stops sending the common signal.

[0088] It should be noted that, as Figure 1As shown in the figure, the terminal access indication system may include multiple adjacent cells. The first cell, the second cell, and the third cell may be adjacent cells with a signal overlapping coverage area. The first cell may be the signal coverage area of the first network device 11, and the second cell may be the signal coverage area of the second network device 12.

The second terminal 14 is a terminal accessing the second network device 12, and may also be referred to as the second terminal 14 accessing the second cell.

[0089] There are message interaction interfaces between different network devices and between network devices and the accessed terminals. It can also be said that there are message interaction interfaces between different adjacent cells and between cells and the accessed terminals.

[0090] The first network device 11 or the second network device 12 may be a base station or a device such as an access point included in the base station. One cell corresponds to one access point, and the terminals within the cell can access the base station through the access point corresponding to the cell.

[0091] The base station may be a base station in Long Term Evolution (LTE), Long Term Evolution Advanced (LTE-A), or an evolved Node B (eNB or eNodeB), a base station device (gNB) in a 5G network, or a base station in a future cell handover system, etc. The base station may include various macro base stations, micro base stations, home base stations, remote radio heads, reconfigurable intelligent surfaces (RISs), routers, relay stations, transmission and reception points (TRPs), receivers, access points, wireless fidelity (WIFI) devices, and other network-side devices. Sometimes the base station may also be referred to as a reader for communicating with the terminal, which is not limited in the embodiments of the present application.

[0092] The first terminal 13 or the second terminal 14 may be a device with wireless transceiver function, such as a vehicle with communication function, a smart car, a mobile phone, a wearable device, a tablet (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in smart grid, a wireless terminal device in transportation safety, a wireless terminal device in smart city, a wireless terminal device in smart home, etc. The embodiments of the present application do not limit this.

[0096] Wherein, the first preset time period is the time period when the first network device stops sending public signals, and the second terminal is a terminal accessing a second cell corresponding to the second network device. The second cell is a cell adjacent to the first cell.

[0097] Optionally, the second cell may be any at least one cell among multiple cells adjacent to the first cell.

[0098] When the first network device and the second network device are different base stations or access points on different base stations, the first indication message may be an interface message between the base stations (such as an Xn interface message). When the first network device and the second network device are different access points on the same base station, the first indication message may be an interface message inside the base station.

[0099] The common signal can be used for terminal time-frequency synchronization, cell access, or signal measurement. For example, the common signal can be the synchronization and system broadcast information (i.e., SSB) or the system information block (SIB), etc.

[0100] The access threshold can be used for terminal access control, that is, when the signal strength of a certain cell measured by the terminal is greater than the access threshold, the terminal can access and camp on that cell. The access threshold can also be referred to as the access gate or the cell access threshold parameter.

[0101] In this embodiment, when the first cell activates the target state (i.e., the first network device stops sending the common signal, and the target state can have more other names), a first indication message can be sent to the adjacent second cell, instructing the second cell to perform a first preset operation (i.e., instructing to prohibit the second terminal from accessing the first cell corresponding to the first network device within the first preset time period) and / or a second preset operation (i.e., reducing the access threshold of the second cell within the first preset time period).

[0102] In response, the second cell can perform the first preset operation, determine the first cell that activates the target state as the prohibited access cell, and instruct the second terminal to prohibit handover or reselection to the first cell during the duration of the target state (i.e., the first preset time period), so as to avoid handover or reselection failure and affect the access performance of the second terminal. The second cell can also perform the second preset operation, reduce the access threshold of the second cell, so that the first terminal under the first cell can more easily access the second cell when the first cell is not accessible, and improve the access success rate of the first terminal.

[0103] In a possible implementation, the first indication message includes at least one of the following: indication information on whether the first network device stops sending the common signal, the length of the first preset time period, the start time of the first preset time period, and the end time of the first preset time period.

[0104] Optionally, the first indication message can carry at least one of the target state activation indication information (i.e., the indication information on whether the first network device stops sending the common signal in this application) and the target state activation time information. The target state activation indication information is used to indicate whether the first cell activates the target state. If the target state activation indication information indicates that the first cell has activated the target state, the first indication message indicates that the first network device stops sending the common signal. If the target state activation indication information indicates that the first cell has not activated the target state, the first indication message indicates that the first network device has not stopped sending the common signal. Not activated can also be referred to as not active, deactivated, or deactivated.

[0105] The target status activation time information includes at least one of the target status activation moment and the target status activation duration. The target status activation moment can be the start moment and / or the end moment of the first preset time period. The target status activation duration is equal to the length of the first preset time period.

[0106] Optionally, when the first indication message only includes the length of the first network device and the start moment of the first preset time period, the first network device can add the start moment of the first preset time period to the length of the first network device to obtain the end moment of the first preset time period, so as to know the first preset time period.

[0107] When the first indication message only includes the length of the first network device and the end moment of the first preset time period, the first network device can subtract the length of the first network device from the end moment of the first preset time period to obtain the start moment of the first preset time period, so as to know the first preset time period.

[0108] Exemplarily, when the first indication message is an interface message between base stations, the cell list included in the first indication message can be as shown in Table 1:

[0109] Table 1

[0110]

[0111]

[0112] As shown in Table 1, the Target Status Activation Indication cell is used to indicate whether the cell (i.e., the first cell) that sends the first indication message activates the target status. The value of this cell can be of the enumerated numerical type (ENUMERATED) or the integer type (INTEGER).

[0113] For example, when the value of Target Status Activation Indication is of the enumerated numerical type and the value of this cell is activated (activated) or True (correct), it indicates that the cell that sends the first indication message has activated the target status. When the value of this cell is deactivated (not activated) or False (error), it indicates that the cell that sends the first indication message has not activated the target status.

[0114] Another example, when the value of Target Status Activation Indication is of the integer type and the value of this cell is the first numerical value N1, it indicates that the cell that sends the first indication message has activated the target status. When the value of this cell is the second numerical value N2, it indicates that the cell that sends the first indication message has not activated the target status.

[0115] The Target Status Activation Duration cell is used to indicate the duration (i.e., the length of time) of the target status activation of the cell that sends the first indication message, and the value of this cell can be of integer type.

[0116] The Target Status Activation Time cell is used to indicate the start time of the target status activation of the cell that sends the first indication message, and the value of this cell can be of bit string type.

[0117] In this embodiment, when the first cell activates the target status, by sending a first indication message to an adjacent second cell, the target status activation time information of the first cell can be sent to the second cell, so that the second cell can perform a preset operation within the corresponding time, avoiding the problem that the terminal cannot access the cell due to the activation of the target status of the first cell, and ensuring the terminal access performance. At the same time, within other times except the target status activation time, the second cell can not perform the preset operation to reduce the signaling overhead of the air interface.

[0118] In a possible implementation manner, the first indication message is used to indicate that when the signal overlap degree between the second cell and the first cell is greater than a first preset threshold, the access threshold of the second cell is reduced within a first preset time period.

[0119] That is to say, the greater the signal overlap degree between the second cell and the first cell, the greater the probability that the terminal of the first cell can access the second cell. When the signal overlap degree between the second cell and the first cell is relatively large, reducing the access threshold of the second cell, the success rate of the terminal of the first cell accessing the second cell is higher.

[0120] In a design, as Figure 3 shown, for a terminal access indication method provided in an embodiment of the present application, before or after the above step S201, the method further includes S301:

[0121] S301. Send a second indication message to the first terminal.

[0122] Wherein, the second indication message is used to indicate that the first terminal switches or reselects to a third cell before the first network device stops sending the common signal. The first terminal is a terminal accessing the first cell. The third cell is a cell adjacent to the first cell.

[0123] Optionally, the second indication message can be a radio resource control (RRC) message. The third cell can be at least one of multiple adjacent cells that the first terminal can access. The third cell can be at least one cell among the second cell and other adjacent cells except the second cell.

[0124] That is to say, before the target state is activated in the first cell, the first cell may send a second indication message to the first terminal, instructing the first terminal to timely switch or reselect to other suitable neighboring cells, so as to avoid access failure caused by the first terminal being unable to access the first cell after the first network device stops sending public signals, and ensure the terminal access performance.

[0125] In a possible implementation, the second indication message includes at least one of the following: indication information on whether the first network device stops sending public signals, the length of the first preset time period, the start time of the first preset time period, the end time of the first preset time period, the identifier of the third cell, the preset handover parameters of the third cell, the preset reselection parameters of the third cell, and the reselection priority of the third cell.

[0126] Wherein, the preset handover parameters include a preset handover threshold and / or a preset handover hysteresis, and the preset reselection parameters include a preset reselection threshold and / or a preset reselection hysteresis.

[0127] Optionally, the second indication message may carry at least one of target state activation indication information, target state activation time, and mobility indication information. The target state activation time may be the start time of the first preset time period. The mobility indication information may carry at least one of the identifier of the third cell and the mobility parameters corresponding to the third cell.

[0128] The mobility parameters corresponding to the third cell may include at least one of a handover threshold (i.e., the preset handover parameter), a reselection threshold (i.e., the preset reselection parameter), and a reselection priority.

[0129] The preset handover threshold is the minimum signal strength that the third cell needs to meet when the terminal hands over from the first cell to the third cell.

[0130] When the terminal measures that the signal strength of the third cell is greater than the signal strength of the first cell, and / or the difference between the signal strength of the third cell and the signal strength of the first cell is greater than the preset handover hysteresis, the terminal may hand over from the first cell to the third cell.

[0131] The preset reselection threshold may be the minimum signal strength that the third cell needs to meet when the terminal reselects from the first cell to the third cell. When the terminal measures that the signal strength of the third cell is greater than the signal strength of the first cell, and / or the difference between the signal strength of the third cell and the signal strength of the first cell is greater than the preset reselection hysteresis, the terminal may reselect from the first cell to the third cell.

[0132] The reselection priority is used to control the order in which the terminal reselects to candidate cells whose signal strengths meet the reselection threshold requirements. When the reselection priority of the third cell is higher than that of the first cell, regardless of the signal strength of the first cell, as long as the signal strength of the third cell is greater than the preset reselection threshold, the terminal can reselect to the third cell.

[0133] When the reselection priority of the third cell is lower than that of the first cell, the terminal can reselect to the third cell only when the signal strength of the first cell is lower than the preset reselection threshold and the signal strength of the third cell is greater than the preset reselection threshold. When the reselection priority of the third cell is equal to that of the first cell, the terminal can reselect to the third cell only when the signal strength of the third cell is greater than the preset reselection threshold, the signal strength of the third cell is greater than the signal strength of the first cell, and the difference between the signal strength of the third cell and the signal strength of the first cell is greater than the preset reselection hysteresis.

[0134] Exemplarily, when the third indication message is an RRC message, the following configuration method can be adopted:

[0135]

[0136]

[0137] Exemplarily, when the second indication message is an RRC message, the list of information elements included in the second indication message can be as shown in Table 2:

[0138] Table 2

[0139]

[0140] In this embodiment, before the first cell activates the target state, by sending a second indication message to the terminal accessing the first cell to instruct the terminal to switch or reselect to other suitable neighboring cells in a timely manner, it is possible to avoid access failures caused by the terminal being unable to access the first cell after the first cell enters the target state, and ensure the terminal access performance. In addition, by carrying mobility indication information in the second indication message, information about accessible neighboring cells can be provided to the terminal as auxiliary information for the terminal to perform cell reselection or handover, improving the success rate of the terminal re-accessing other neighboring cells.

[0141] Table 3

[0142]

[0143]

[0144] In a possible implementation, the second indication message is used to instruct the first terminal to access the third cell before the start time of the first preset time period.

[0145] That is to say, specifically before the first network device stops sending the common signal, it can be before the start time of the first preset time period. That is, the second indication message is used to instruct the first terminal to re-attach to the third cell before the target state activation time.

[0146] It should be noted that for the method of determining the third cell, reference can be made to the following embodiments.

[0147] In one design, as Figure 4 shown, for a terminal access indication method provided in an embodiment of the present application, before the above step S301, the method further includes S401 - S402:

[0148] S401. Obtain the signal overlap degree between each of a plurality of fourth cells and the first cell.

[0149] Among them, the fourth cell is a cell adjacent to the first cell.

[0150] For the introduction on how to calculate the signal overlap degree, reference can be made to the embodiments in S501 - S503 below, which will not be elaborated here.

[0151] S402. Based on the signal overlap degree between each of the plurality of fourth cells and the first cell, determine the third cell from the plurality of fourth cells.

[0152] Among them, the signal overlap degree between the third cell and the first cell is greater than a second preset threshold.

[0153] That is to say, the larger the area of the signal overlap region between the fourth cell and the first cell, the greater the signal overlap degree between the fourth cell and the first cell, indicating that the probability of the terminal in the fourth cell being able to access the third cell is greater, and at this time, the success rate of instructing the terminal in the first cell to switch or reselect to the fourth cell is higher.

[0154] In one design, as Figure 5 shown, for a terminal access indication method provided in an embodiment of the present application, the method in the above step S401 specifically includes S501 - S503:

[0155] S501. For any one of the plurality of fourth cells, obtain a plurality of first measurement reports sent by the terminals accessing the first cell.

[0156] Among them, the first measurement report includes the signal strength of the first cell and the signal strength of the fourth cell.

[0157] Optionally, for any one of the plurality of fourth cells, the first network device can obtain a plurality of first measurement reports sent by all the terminals accessing the first cell within a preset time period.

[0158] S502. Determine a second measurement report from multiple first measurement reports.

[0159] Among them, the difference between the signal strength of the first cell included in the second measurement report and the signal strength of the fourth cell is less than a third preset threshold.

[0160] Furthermore, if the first network device detects that the difference between the signal strength of the first cell and the signal strength of the fourth cell carried in a certain measurement report among multiple first measurement reports is less than the third preset threshold, the first network device may determine this measurement report as the target measurement report (i.e., the second measurement report).

[0161] S503. Determine the ratio between the number of second measurement reports and the number of multiple first measurement reports as the signal overlap degree between the fourth cell and the first cell.

[0162] Furthermore, determine the ratio between the number of target measurement reports and the number of all measurement reports (i.e., multiple first measurement reports) as the signal overlap degree between the fourth cell and the first cell.

[0163] That is to say, the smaller the difference between the signal strength of the first cell and the signal strength of the fourth cell in the measurement report of the terminal, the greater the possibility that the terminal is located in the signal overlapping coverage area between the first cell and the fourth cell. Furthermore, the more such measurement reports, the larger the signal overlapping coverage area between the first cell and the fourth cell, that is, the greater the signal overlap degree between the fourth cell and the first cell.

[0164] For the introduction on how to determine the first preset time period, reference can be made to the following embodiments.

[0165] In one design, as Figure 6 shown, for a terminal access indication method provided in an embodiment of the present application, before the above step S201, the method further includes S601 - S602:

[0166] S601. Obtain the cell load of the first cell in each measurement period included in the second preset time period.

[0167] Optionally, the first network device may obtain the cell load of the first cell in each measurement period included in the second preset time period. The second preset time period may be a certain preset future time period. The measurement period may be the statistical interval of the cell load. The cell load may be any at least one of parameters such as the number of access users, the cell radio resource utilization rate, and the service traffic.

[0168] Exemplarily, assume that the current time is 10:00, then a preset future time period can be any reasonable time period such as 10:00 - 11:00, or 10:00 - 11:40, etc. The measurement period can be any reasonable value such as 1 s, 1 min, 15 min, etc. For example, when the second preset time period is 10:00 - 11:40 and the measurement period is 1 min, it can be known that the second preset time period includes 100 measurement periods, which are {T0, T1, T2, ..., T100} respectively. The cell loads of the first cell within these 100 measurement periods can be {L0, L1, L2, ..., L100} respectively.

[0169] S602. Based on the cell load of the first cell within each measurement period, determine the time period corresponding to at least one measurement period among the multiple measurement periods as the first preset time period.

[0170] Among them, the cell load of the first cell within each measurement period of at least one measurement period is less than the fourth preset threshold (i.e., the preset load threshold).

[0171] Optionally, based on the cell load of the first cell within each measurement period, the first network device can determine the time period corresponding to at least one measurement period among the multiple measurement periods as the first preset time period, where the length of the first preset time period is not greater than the second preset time period.

[0172] Exemplarily, if the cell loads {L2, L3, ..., L21} of the first cell corresponding to 20 consecutive measurement periods starting from T2 in {T0, T1, T2, ..., T100} are all less than the preset load threshold, then the first network device can determine the first preset time period as 20 consecutive measurement periods {T2, T3, ..., T21} starting from T2, that is, 10:02 - 10:21.

[0173] In this embodiment, by predicting the cell load within the future time period, the target time period with a lower cell load (i.e., the first preset time period in the present disclosure) is determined to activate the target state and stop sending the common signal within the target time period. That is, the lower the cell load, the fewer terminals need to access the cell. At this time, the cell stops sending the common signal, which has less impact on users and can save the power consumption of the network device, achieving the energy-saving effect. In addition, sending the common signal during the time period with a higher cell load can meet the needs of terminals to access the cell.

[0174] In a possible implementation manner, at least one measurement period is a consecutive measurement period.

[0175] That is to say, by using the measurement period with continuous low cell load as the target period, it is possible to avoid frequent switching of the cell between the active and deactivated target states due to cell load fluctuations, thereby reducing the control signaling overhead.

[0176] For the introduction on how to obtain the cell load of the first cell in the future time period, reference can be made to the following embodiments.

[0177] In one design, as Figure 7 shown, a terminal access indication method provided by an embodiment of the present application, the method in step S601 specifically includes S701:

[0178] S701: Input the second preset time period into a preset model to obtain the cell load of the first cell in each measurement period among multiple measurement periods.

[0179] That is to say, the first network device can predict the cell load of the first cell in each measurement period included in the future time period through a preset prediction model (i.e., the preset model), improving the accuracy of predicting the cell load.

[0180] Optionally, the preset model can be a time series prediction model. For example, a linear model based on Bayesian (PROPHET), an autoregressive integrated moving average model (ARIMA), a long short-term memory network (LSTM), etc.

[0181] In a possible implementation manner, the preset model is trained through the following method:

[0182] S1: Obtain a training set. The training set includes: the cell load of the first cell in each measurement period among multiple measurement periods included in each historical time period of multiple historical time periods.

[0183] S2: Input the training set into an initial model for training to obtain the preset model.

[0184] Optionally, the historical time period can be a preset historical period. For any preset historical period, the first network device can obtain the load statistical value (i.e., the cell load of the first cell) in each measurement period included in the preset historical period as training data, and train a preset prediction model (i.e., the initial model) to obtain a trained prediction model (i.e., the preset model). Further, the first network device can input the second preset time period into the trained prediction model to obtain the load prediction value corresponding to each measurement period included in the second preset time period.

[0185] That is to say, training the model according to the cell load of the first cell in the measurement period included in the historical time period can improve the accuracy of the preset model in predicting the cell load.

[0186] In one design, as Figure 8 shown, a method for indicating terminal access provided by an embodiment of the present application is applied to a second network device. The method includes S801:

[0187] S801. In response to a first indication message from a first network device, prohibit a second terminal from accessing a first cell corresponding to the first network device within a first preset time period, and / or reduce an access threshold of a second cell within the first preset time period.

[0188] Wherein, the first preset time period is a time period during which the first network device stops sending a common signal, the second terminal is a terminal accessing a second cell corresponding to the second network device, and the second cell is a cell adjacent to the first cell.

[0189] Optionally, in response to the first indication message from the first network device, the second network device may prohibit the second terminal from accessing the first cell corresponding to the first network device within the first preset time period (i.e., perform a first preset operation), and / or reduce the access threshold of the second cell within the first preset time period (i.e., perform a second preset operation).

[0190] For the introduction of the first indication message, the common signal, and the access threshold, reference may be made to the above-mentioned embodiment S201, which will not be elaborated here.

[0191] In this embodiment, after the first cell activates the target state, terminals under both the first cell and the second cell cannot access the first cell. To ensure the access performance of the terminals, the second network device may perform the first preset operation to prohibit the terminals under the second cell from reselecting or switching to the first cell, thereby avoiding reselection or handover failures and affecting the access performance of the second terminal. The second network device may also perform the second preset operation to reduce the access threshold of the second cell, so that when the terminals under the first cell cannot access the first cell, they can more easily access the second cell, improving the terminal access success rate.

[0192] In a possible implementation manner, the first indication message includes at least one of the following: indication information on whether the first network device stops sending a common signal, the length of the first preset time period, the start time of the first preset time period, and the end time of the first preset time period.

[0193] For the introduction of the parameters included in the first indication message, reference may be made to the above-mentioned embodiment S201, which will not be elaborated here.

[0194] In one design, as Figure 9 shown, a method for indicating terminal access provided by an embodiment of the present application. The "prohibit the second terminal from accessing the first cell corresponding to the first network device within the first preset time period" in the above step S801 specifically includes S901:

[0195] S901. Send a third indication message to the second terminal.

[0196] Among them, the third indication message is used to indicate that the second terminal is prohibited from accessing the first cell within the first preset time period.

[0197] Optionally, if the second forwarding device determines the activation target state of the first cell according to the first indication message, the second forwarding device may determine the first cell as a prohibited access cell and send a third indication message to the second terminal, which is used to indicate that the second terminal is prohibited from switching or reselecting to the first cell during the duration of the target state (i.e., the first preset time period), so as to prevent the second terminal from switching or reselecting to the first cell.

[0198] The third indication message may be an RRC message.

[0199] In a possible implementation manner, the third indication message includes at least one of the following: indication information on whether to prohibit access to the first cell, the identifier of the first cell, the length of the first preset time period, the start time of the first preset time period, and the end time of the first preset time period.

[0200] Optionally, the third indication message may carry at least one of the following information: cell prohibition indication (i.e., the indication information on whether to prohibit access to the first cell in the present disclosure), the identifier of the prohibited access cell (i.e., the identifier of the first cell in the present disclosure), the activation duration of the target state, and the activation time of the target state.

[0201] Table IV

[0202]

[0203]

[0204] Exemplarily, when the third indication message is an RRC message, the following configuration method may be adopted:

[0205]

[0206] Exemplarily, when the third indication message is an RRC message, the list of information elements included in the third indication message may be as shown in Table IV.

[0207] Exemplarily, if the value of the Cell Prohibited information element is True or M1, the terminal cannot switch or reselect to the cell indicated by the Prohibited cell Id within the duration indicated by the Target StatusDuration. If the value of this information element is False or M2, the terminal is allowed to switch or reselect to the cell indicated by the Prohibited cell Id.

[0208] If the value of Cell Prohibited is True or M1, the cell indicated by Prohibited Cell Id is prohibited within the Target Status Duration.

[0209] In this embodiment, when the second cell receives the first indication message, it determines the first cell in the target state as the prohibited access cell and sends a third indication message to the second terminal, which carries information such as the identifier of the prohibited access cell, the target state activation duration, and the target state activation time, for indicating that the second terminal is prohibited from switching or reselecting to the prohibited access cell within the target state duration. In this way, it is possible to avoid the problem of cell access failure caused by the terminal initiating reselection or handover to the first cell during the target state activation time, and ensure the terminal access performance.

[0210] In one design, as Figure 10 shown, for a terminal access indication method provided in an embodiment of the present application, "reducing the access threshold of the second cell within the first preset time period" in step S801 above specifically includes S1001:

[0211] S1001. When the signal overlap degree between the second cell and the first cell is greater than the first preset threshold, reduce the access threshold of the second cell within the first preset time period.

[0212] That is to say, the greater the signal overlap degree between the second cell and the first cell, the greater the probability that the terminal of the first cell can access the second cell. When the signal overlap degree between the second cell and the first cell is relatively large, reducing the access threshold of the second cell can increase the success rate of the terminal of the first cell accessing the second cell.

[0213] For the introduction of how to calculate the signal overlap degree, reference can be made to the embodiments in S1101 - S1103 below, which will not be elaborated here.

[0214] In one design, as Figure 11 shown, for a terminal access indication method provided in an embodiment of the present application, before the above step S1001, the method further includes S1101 - S1103:

[0215] S1101. Obtain multiple third measurement reports sent by the terminals accessing the second cell.

[0216] Among them, the third measurement report includes the signal strength of the first cell and the signal strength of the second cell.

[0217] Optionally, the second network device may obtain multiple third measurement reports sent by all terminals accessing the second cell within a preset duration.

[0218] S1102. Determine a fourth measurement report from multiple third measurement reports.

[0219] Among them, the difference between the signal strength of the second cell included in the fourth measurement report and the signal strength of the first cell is less than a third preset threshold.

[0220] Furthermore, if the second network device detects that the difference between the signal strength of the second cell and the signal strength of the first cell carried in a certain measurement report among multiple first measurement reports is less than the third preset threshold, the second network device may determine this measurement report as the target measurement report (i.e., the fourth measurement report).

[0221] S1103. Determine the ratio between the number of fourth measurement reports and the number of multiple third measurement reports as the signal overlap degree between the second cell and the first cell.

[0222] Furthermore, determine the ratio between the number of target measurement reports and the number of all measurement reports (i.e., multiple third measurement reports) as the signal overlap degree between the second cell and the first cell.

[0223] That is to say, the smaller the difference between the signal strength of the second cell and the signal strength of the first cell in the measurement report of the terminal, the greater the possibility that the terminal is located in the signal overlapping coverage area between the second cell and the first cell. Furthermore, the more such measurement reports there are, the larger the signal overlapping coverage area between the second cell and the first cell, that is, the greater the signal overlap degree between the second cell and the first cell.

[0224] In one design, as Figure 12 shown, a terminal access indication method provided in an embodiment of the present application is applied to a first terminal, and the first terminal is a terminal accessing a first cell corresponding to a first network device. The method includes S1201:

[0225] S1201. In response to a second indication message from the first network device, switch or reselect to a third cell before the first network device stops sending a common signal.

[0226] Among them, the third cell is a cell adjacent to the first cell.

[0227] For the introduction of the role of the first terminal switching or reselecting to the third cell before the first network device stops sending the common signal, reference may be made to the above embodiments, which will not be elaborated here.

[0228] In a possible implementation manner, the second indication message includes at least one of the following: indication information on whether the first network device stops sending a common signal, the length of a first preset time period during which the first network device stops sending the common signal, the start time of the first preset time period, the end time of the first preset time period, the identifier of the third cell, the preset handover parameters of the third cell, the preset reselection parameters of the third cell, and the reselection priority of the third cell. Wherein, the preset handover parameters include a preset handover threshold and / or a preset handover hysteresis, and the preset reselection parameters include a preset reselection threshold and / or a preset reselection hysteresis.
