The terminal involved in the embodiments of the present disclosure may also include a normal terminal. A normal terminal may also be referred to as a normal terminal. A normal terminal may also be understood as a non-Redcap terminal (non-Redcap terminal) and a non-eRedcap terminal (non-eRedcap terminal).

[0145] The terminal needs to access a cell during wireless communication. In the related art, corresponding cell access configuration information is configured for normal terminals and Redcap terminals.

[0146] For normal terminals, the master information block (MIB) contains 1-bit indication information to indicate whether the terminal is allowed to reside in the cell for cell access control. Among them, the 1-bit indication information can also be called cell bar. If the cell bar takes effect, the terminal is not allowed to reside in the cell. The terminal further interprets the intra-frequency cell reselection identification (IFRI) field contained in the MIB to see whether intra-frequency cell reselection can be performed. Among them, by setting the IFRI field, when the system load is relatively serious in the same frequency band, the configuration does not support intra-frequency cell reselection for this type of terminal.

[0147] For Redcap terminals, the capabilities are different from those of normal terminals, such as Redcap terminals have a lower number of receiving antennas, smaller size / channel bandwidth, etc. In some cases, in order to avoid affecting the services of normal terminals, it is sometimes necessary to shut down the services for Redcap terminals. In addition, the cells that support the access of Redcap terminals need to undergo corresponding network transformation and upgrades, and not all networks can naturally support Redcap terminals. For networks that have not been upgraded, the access of Redcap terminals can be avoided by indicating that the cell is prohibited from access. In short, considering the above factors, it is necessary to introduce corresponding cell access control designs for Redcap terminals. Specifically, its working mechanism is as follows: Rel-17 Redcap terminals first read the cell bar field in the MIB. If the field indicates that access to the cell is not allowed, the Redcap terminal further reads the IFRI field carried in the MIB to check whether the same-frequency cell reselection can be performed. If the cell bar field in the MIB indicates that access to the cell is allowed, the terminal will further read the cell bar and IFRI fields specially configured for the Redcap terminal in the system information block 1 (SIB1) to further check whether it can reside in the cell and / or perform the same-frequency cell reselection. In addition, since different receiving antennas are configured with different transmission efficiencies and different coverage ranges, the cell bar indication carried in SIB1 for Redcap terminals needs to be defined separately for terminals with one receiving antenna (1RX) and terminals with two receiving antennas (2RX). The IFRI indication does not distinguish the number of antennas, that is, 1RX and 2RX users use the same 1-bit indication bit for IFRI indication.

[0148] The related technology further introduces the eRedcap terminal. The terminal capability of the eRedcap terminal is further reduced compared to the Redcap terminal. For example, the bandwidth of the eRedcap terminal is further reduced to 5MHZ, and the processing time is also relaxed. Therefore, if the same cell access control mechanism as the Redcap terminal is used to control the cell access of the eRedcap terminal, it may affect the scheduling and spectrum efficiency of the network, and may also have a certain impact on the transmission performance of the terminal. Therefore, based on the introduction of the eRedcap terminal, a new cell access control method needs to be provided to balance the network load, while avoiding the introduction of unnecessary delays or energy consumption overhead to the terminal for cell access.

[0149] In the cell access control method provided by the embodiment of the present disclosure, corresponding cell access indication information is allocated and configured for different types of terminals to perform cell access control.

[0150] In the embodiments of the present disclosure, the terminal involves three different types of terminals, which are referred to as the first type terminal, the second type terminal and the third type terminal for convenience of description. Among them, different types of terminals have different capabilities in the embodiments of the present disclosure. Among them, the capability of the first type terminal is greater than that of the second type terminal, and the capability of the second type terminal is greater than that of the third type terminal. In some possible implementations, the first type terminal may be an ordinary terminal; the second type terminal may be a Redcap terminal (or NR-lite for short); and the third type terminal may be an eRedcap terminal.

[0151] For example, the capabilities of the terminal may be transceiver bandwidth, number of transceiver antennas, maximum number of bits of a transmission block, duplex type, and processing time delay, etc. The different capabilities of the terminals may be different in one or more of the transceiver bandwidth, number of transceiver antennas, maximum number of bits of a transmission block, duplex type, and processing time delay. In one example, the first type of terminal may be a normal terminal, the second type of terminal may be a Redcap terminal, and the third type of terminal may be an eRedcap terminal.

[0152] Figure 2 is a flow chart of a cell access control method according to an exemplary embodiment. Figure 2 As shown, the cell access control method is used in a terminal, which may be an eRedcap terminal, for example. The cell access control method includes the following steps S11 to S12.

[0153] In step S11, cell access configuration information is determined.

[0154] The cell access configuration information is used to configure cell access indication information of different types of terminals, for example, to configure cell access indication information of at least one of the following types of terminals: first type of terminals, second type of terminals, and third type of terminals.

[0155] For the convenience of description in the embodiments of the present disclosure, the cell access indication information configured for the first type of terminal is referred to as the first cell access indication information. The cell access indication information configured for the second type of terminal is referred to as the second cell access indication information. The cell access indication information configured for the third type of terminal is referred to as the third cell access indication information.

[0156] In one example, the cell access configuration information is used to configure first cell access indication information corresponding to a first type of terminal, second cell access indication information corresponding to a second type of terminal, and third cell access indication information corresponding to a third type of terminal.

[0157] In an exemplary embodiment of the present disclosure, the first type of terminal may be a normal terminal, the second type of terminal may be a Redcap terminal, and the third type of terminal may be an eRedcap terminal. Among them, the first cell access indication information may be the cell access indication information configured for the normal terminal in the MIB. The second cell access indication information may be the cell access indication information configured for the Redcap terminal in the MIB. The third cell access indication information may be an independent cell access indication information configured for the eRedcap terminal, and the independent cell access indication information is different from the first cell access indication information, and different from the second cell access indication information. Of course, in an embodiment of the present disclosure, the first cell access indication information, the second cell access indication information, and the third cell access indication information may be different fields of the same message, or may be different messages; at the same time, the first cell access indication information, the second cell access indication information, and the third cell access indication information (for example, different values) may also be indicated by the same field of the same message; the specific implementation method is no longer limited here.

[0158] In the embodiment of the present disclosure, the cell access configuration information may be configured by a network device. The terminal receives the cell access configuration information configured by the network device for the terminal, and determines whether to perform a corresponding operation according to the cell access configuration information; the corresponding operation may be at least one of the following: whether to access the current cell, whether to reselect the same frequency cell.

[0159] In an exemplary embodiment of the present disclosure, the terminal may obtain the first cell access indication information and / or obtain the second cell access indication information by using a solution similar to the conventional technology or any other appropriate solution, which will not be described in detail herein. Different from the conventional technology, the terminal may obtain the third cell access indication information.

[0160] In step S12, third cell access indication information is obtained.

[0161] In the disclosed embodiment, the cell access configuration information is used to configure the cell access indication information of different types of terminals. When the terminal is an eRedcap terminal, the cell access indication for cell access can be determined according to the third cell access indication information, thereby balancing the network load and improving the transmission performance of the terminal for cell access.

[0162] The following describes a process in which the terminal obtains the third cell access indication information and implements the cell access.

[0163] In the embodiment of the present disclosure, the third cell access indication information may be carried by at least one of the following information: MIB, SIB1, other system information (OSI), and downlink control information (DCI).

[0164] In one implementation of the embodiments of the present disclosure, the first cell access indication information, the second cell access indication information, and the third cell access indication information include cell access prohibition indication information (cell bar) for indicating whether a terminal of a type corresponding to the cell access indication information is allowed to reside in the cell. In one implementation of the embodiments of the present disclosure, the first cell access indication information, the second cell access indication information, and the third cell access indication information include cell access prohibition indication information (cell bar) for indicating whether a terminal of a type corresponding to the cell access indication information is allowed to reside in the cell.

[0165] In the embodiment of the present disclosure, only the third cell access indication information may be included; one or both of the first cell access indication information and the second cell access indication information may also be additionally included.

[0166] For example, the cell access prohibition indication information included in the first cell access indication information may be cell bar indication information configured for a normal terminal, and the first cell access indication information is used to indicate whether a first type of terminal is allowed to access the cell. The cell access prohibition indication information included in the second cell access indication information may be cell bar indication information configured for a Redcap terminal, and the second cell access indication information is used to indicate whether a second type of terminal is allowed to access the cell. The cell access prohibition indication information included in the third cell access indication information may be cell bar indication information configured for an eRedcap terminal, and the third cell access indication information is used to indicate whether a second type of terminal is allowed to access the cell. As mentioned above, the first cell access indication information, the second cell access indication information, and the third cell access indication information may be different fields of the same message, or may be different messages; at the same time, the first cell access indication information, the second cell access indication information, and the third cell access indication information (for example, different values) may also be indicated by the same field of the same message; the specific implementation method is no longer limited here. For example, if the cell access prohibition indication information included in the second cell access indication information may be cell bar indication information configured for Redcap terminals and cell bar indication information configured for eRedcap terminals, it may simultaneously indicate whether the cell allows Redcap terminals and eRedcap terminals to access.

[0167] In the embodiment of the present disclosure, the cell access prohibition indication information included in the third cell access indication information may be carried by at least one of the following information: MIB, SIB1, OSI, and DCI. For example, the independent cell bar indication information configured for the eRedcap terminal may be carried by at least one of the following information: MIB, SIB1, OSI, and DCI.

[0168] In one implementation, in the embodiment of the present disclosure, the cell access prohibition indication information included in the third cell access indication information may be carried in SIB1.

[0169] On the one hand, in the embodiment of the present disclosure, the SIB1 carrying the cell access prohibition indication information included in the third cell access indication information is different from the SIB1 carrying the cell access prohibition indication information included in the second indication information. Among them, for the convenience of description, the SIB1 carrying the cell access prohibition indication information included in the third cell access indication information is referred to as the first SIB1. The SIB1 carrying the cell access prohibition indication information included in the second indication information is referred to as the second SIB1. In one example, the first SIB1 is used to carry independent cell bar indication information configured for the eRedcap terminal. The second SIB1 is used to carry the cell bar indication information configured for the Redcap terminal. It can also be understood that the SIB1 configured by the network device in the embodiment of the present disclosure includes the first SIB1 and the second SIB1. In a possible implementation method, the first SIB1 can be a SIB1 specifically for the eRedcap terminal. Because the bandwidth supported by the eRedcap terminal is relatively small, the payload size of this separate SIB1 may also be smaller.

[0170] On the other hand, in the embodiment of the present disclosure, the SIB1 carrying the cell access prohibition indication information included in the third cell access indication information and the SIB1 carrying the cell access prohibition indication information included in the second indication information are the same SIB1.

[0171] In one implementation of the disclosed embodiment, when the first SIB1 is configured, the cell access prohibition indication information included in the second indication information can be carried in the first SIB. In one example, the cellbar indication information configured for the eRedcap terminal and the cell bar indication information configured for the Redcap terminal are both carried in the first SIB1.

[0172] In another implementation of the disclosed embodiment, the cell access prohibition indication information of the second type of terminal and the third type of terminal is indicated by the same SIB1. The SIB1 may be the second SIB1 in the conventional technology. In a possible implementation, the cell access prohibition indication information of the second type of terminal and the third type of terminal may be indicated by different fields of the same SIB1 or the same field. For example, the SIB1 includes a field for indicating the cell bar indication information configured for the eRedcap terminal, and a field for indicating the cell bar indication information configured for the Redcap terminal. In a possible implementation, the cellbar indication information configured for the Redcap terminal and the cell bar indication information configured for the eRedcap terminal may be indicated by different values ​​of the same field of SIB1.

[0173] Further, in the embodiment of the present disclosure, when the third cell access indication information is carried by DCI, the DCI may be a DCI for indicating SIB1 (DCI for SIB1), or may be a DCI for indicating OSI (DCI for OSI).

[0174] Among them, in the embodiment of the present disclosure, the cell access prohibition indication information included in the third cell access indication information can correspond to the same receiving antenna or to different receiving antennas. For example, the eRedcap terminals of 1RX and 2RX can be indicated by the same cell access prohibition indication information or by different cell access prohibition indication information. For example, the bit position indicating the cell access prohibition indication information is 2 bits, wherein the high bit position is used to indicate whether the eRedcap terminal of 1RX is allowed to access the cell, and the low bit position is used to indicate whether the eRedcap terminal of 2RX is allowed to access the cell, or vice versa.

[0175] In one implementation, the cell access prohibition indication information indicated by the third cell access indication information is different from the cell access prohibition indication information indicated by the second cell access indication information and the first cell access indication information. In one example, the cell bar indication information configured for the eRedcap terminal is independent of the cell bar indication information configured for the normal terminal and the Redcap terminal, that is: the cell access prohibition indication information for the eRedcap terminal is indicated by an independent cell bar indication information, and the cell access prohibition indication information for the normal terminal and the Redcap terminal is indicated by another cell bar indication information. In another implementation, the cell access prohibition indication information indicated by the third cell access indication information is the cell access prohibition indication information indicated by the second cell access indication information. In one example, the cell bar indication information configured for the Redcap terminal is used as the cell bar indication information of the eRedcap terminal to indicate whether the eRedcap terminal is allowed to access the cell. That is: the cell access prohibition indication information for the eRedcap terminal and the Redcap terminal is indicated by a cell bar indication information.

[0176] In the embodiment of the present disclosure, the following describes the implementation process of the terminal obtaining the third cell access indication information when the cell access prohibition indication information indicated by the third cell access indication information is different from the cell access prohibition indication information indicated by the second cell access indication information and the first cell access indication information.

[0177] In the embodiment of the present disclosure, when the eRedcap terminal performs cell access, it can determine whether to stay in the current cell based on at least one of the cell access prohibition indication information indicated by the first cell access indication information, the cell access prohibition indication information indicated by the second cell access indication information, and the cell access prohibition indication information indicated by the third cell access indication information. For example, the following situations may be included:

[0178] Scenario 1: determining whether to stay in the current cell based on the cell access prohibition indication information indicated by the first cell access indication information, the cell access prohibition indication information indicated by the second cell access indication information, and the cell access prohibition indication information indicated by the third cell access indication information.

[0179] In which, in response to the cell access prohibition indication information indicated by the first cell access indication information indicating that staying in the cell is allowed, and the cell access prohibition indication information indicated by the second cell access indication information indicating that staying in the cell is allowed, the terminal obtains the cell access prohibition indication information indicated by the third cell access indication information.

[0180] In one example, if the eRedcap terminal reads the cell bar indication information in the MIB indicating that the cell is allowed to be resident, and reads the corresponding indication field of the cell bar indication information configured for the Redcap terminal in SIB1 indicating that the cell is allowed to be resident, the eRedcap terminal further reads independent cell bar indication information designed specifically for the eRedcap terminal.

[0181] Among them, in the embodiment of the present disclosure, based on the cell access prohibition indication information indicated by the first cell access indication information, the cell access prohibition indication information indicated by the second cell access indication information, and the cell access prohibition indication information indicated by the third cell access indication information, when determining whether to reside in the current cell, the cell access prohibition indication information indicated by the third cell access indication information can be carried in the first SIB1. For example, an independent SIB1 is designed for the eRedcap terminal to carry the cell bar indication information corresponding to the eRedcap terminal.

[0182] In one implementation, the first SIB1 carrying the cell access prohibition indication information indicated by the third cell access indication information may also carry the cell access prohibition indication information indicated by the second cell access indication information. For example, an independent SIB1 designed for an eRedcap terminal carries the cell bar indication information corresponding to the eRedcap terminal and carries the cell bar indication information corresponding to the Redcap terminal.

[0183] Scenario 2: determining whether to stay in the current cell based on the cell access prohibition indication information indicated by the second cell access indication information and the cell access prohibition indication information indicated by the third cell access indication information.

[0184] In which, in response to the cell access prohibition indication information indicated by the second cell access indication information indicating that camping on the cell is allowed, the terminal further acquires the cell access prohibition indication information indicated by the third cell access indication information.

[0185] In one example, the eRedcap terminal ignores the cell bar indication information in the MIB and reads the cell bar indication information configured for the Redcap terminal in SIB1. If the cell bar indication information configured for the Redcap terminal indicates that the cell is allowed to reside, the eRedcap terminal further reads the independent cell bar indication information configured for the eRedcap terminal.

[0186] Among them, when determining whether to stay in the current cell based on the cell access prohibition indication information indicated by the second cell access indication information and the cell access prohibition indication information indicated by the third cell access indication information, the cell access prohibition indication information indicated by the third cell access indication information can be carried in the first SIB1. For example, an independent SIB1 is designed for the eRedcap terminal to carry the cell bar indication information corresponding to the eRedcap terminal.

[0187] In one implementation, the first SIB1 carrying the cell access prohibition indication information indicated by the third cell access indication information may also carry the cell access prohibition indication information indicated by the second cell access indication information. For example, an independent SIB1 designed for an eRedcap terminal carries the cell bar indication information corresponding to the eRedcap terminal and carries the cell bar indication information corresponding to the Redcap terminal.

[0188] Scenario three: determining whether to stay in the current cell based on the cell access prohibition indication information indicated by the first cell access indication information and the cell access prohibition indication information indicated by the third cell access indication information.

[0189] In which, in response to the cell access prohibition indication information indicated by the first cell access indication information indicating that camping on the cell is allowed, the cell access prohibition indication information indicated by the third cell access indication information is acquired.

[0190] In an embodiment of the present disclosure, when the eRedcap terminal determines whether to stay in the current cell based on the cell access prohibition indication information indicated by the first cell access indication information and the cell access prohibition indication information indicated by the third cell access indication information, the cell access prohibition indication information indicated by the second cell access indication information can be ignored.

[0191] In one example, when the eRedcap terminal reads the cell bar indication information in the MIB as allowing residence, it ignores the cell bar indication information configured for the Redcap terminal in SIB1, and further reads the independent cell bar indication information configured for the eRedcap terminal.

[0192] In the embodiment of the present disclosure, when the terminal determines whether to stay in the current cell based on the cell access prohibition indication information indicated by the first cell access indication information and the cell access prohibition indication information indicated by the third cell access indication information, the following situations may be included:

[0193] In a first aspect, the terminal may always ignore the cell access prohibition indication information indicated by the second cell access indication information.

[0194] On the second aspect, in the embodiments of the present disclosure, when the first SIB1 is used to carry the cell access prohibition information indicated by the third cell access indication information, the cell access prohibition indication information indicated by the second cell access indication information may be ignored.

[0195] On the third aspect, in an embodiment of the present disclosure, when OSI is used to carry the cell access prohibition information indicated by the third cell access indication information, the cell access prohibition indication information indicated by the second cell access indication information may be ignored.

[0196] Fourthly, in an embodiment of the present disclosure, when using DCI to carry the cell access prohibition information indicated by the third cell access indication information, the cell access prohibition indication information indicated by the second cell access indication information may be ignored.

[0197] Scenario 4: determining whether to stay in the current cell based on the cell access prohibition indication information indicated by the third cell access indication information.

[0198] Among them, the eRedcap terminal ignores the cell access prohibition indication information indicated by the first cell access indication information and ignores the cell access prohibition indication information indicated by the second cell access indication information, and directly obtains the cell access prohibition indication information indicated by the third cell access indication information.

[0199] In one example, the terminal ignores the cell bar indication information in the MIB and ignores the cell bar indication information configured for the Redcap terminal in the SIB1, and reads the independent cell bar indication information configured for the eRedcap terminal.

[0200] In the embodiment of the present disclosure, when the cell access prohibition indication information indicated by the third cell access indication information is the cell access prohibition indication information indicated by the second cell access indication information, the cell access prohibition indication information indicated by the third cell access indication information can be carried in the first SIB1. For example, an independent SIB1 is designed for the eRedcap terminal to carry the cell bar indication information corresponding to the eRedcap terminal.

[0201] In one implementation, the first SIB1 carrying the cell access prohibition indication information indicated by the third cell access indication information may also carry the cell access prohibition indication information indicated by the second cell access indication information. For example, an independent SIB1 designed for an eRedcap terminal carries the cell bar indication information corresponding to the eRedcap terminal and carries the cell bar indication information corresponding to the Redcap terminal.

[0202] In the disclosed embodiment, the terminal can determine whether to stay in the current cell when performing cell access through the cell access prohibition indication information involved in the above implementation. When the terminal determines that it can stay in the current cell, it stays in the current cell. When the terminal determines that it cannot stay in the current cell, it can further determine whether to perform intra-frequency cell reselection.

[0203] In one implementation, the first cell access indication information, the second cell access indication information, and the third cell access indication information in the disclosed embodiment include an IFRI for indicating whether the terminal is allowed to reselect the same-frequency cell. That is, the first cell access indication information, the second cell access indication information, and the third cell access indication information may include cell access prohibition indication information for indicating a cell bar, and may also include an IFRI for indicating whether the terminal is allowed to reselect the same-frequency cell, and may also include both cell access prohibition indication information for indicating a cell bar and an IFRI for indicating whether the terminal is allowed to reselect the same-frequency cell.

[0204] Similar to the aforementioned implementation, the IFRI of whether the terminal is allowed to reselect the same-frequency cell included in the first cell access indication information may be configured for a normal terminal, and the first cell access indication information is used to indicate whether the first type of terminal is allowed to reselect the same-frequency cell. The IFRI of whether the terminal is allowed to reselect the same-frequency cell included in the second cell access indication information may be configured for a Redcap terminal, and the second cell access indication information is used to indicate whether the second type of terminal is allowed to reselect the same-frequency cell. The IFRI of whether the terminal is allowed to reselect the same-frequency cell included in the third cell access indication information may be configured for an eRedcap terminal, and the third cell access indication information is used to indicate whether the third type of terminal is allowed to reselect the same-frequency cell.

[0205] In the embodiment of the present disclosure, only the third cell access indication information may be included; one or both of the first cell access indication information and the second cell access indication information may also be additionally included.

[0206] As mentioned above, the first cell access indication information, the second cell access indication information, and the third cell access indication information can be different fields of the same message, or different messages; at the same time, the first cell access indication information, the second cell access indication information, and the third cell access indication information (for example, different values) can also be indicated by the same field of the same message; the specific implementation method is no longer limited here. For example, if the IFRI included in the second cell access indication information indicating whether the terminal is allowed to reselect the same-frequency cell can be the cell bar indication information configured for the Redcap terminal and the cell bar indication information configured for the eRedcap terminal, it can simultaneously indicate whether the cell allows the Redcap terminal and the eRedcap terminal to access.

[0207] In the following implementation, the cell access prohibition indication information for indicating the cell bar and the IFRI for indicating whether the terminal is allowed to reselect the same frequency cell are used as an example for explanation. However, it can be understood by those skilled in the art that the following implementations can include only the IFRI for indicating whether the terminal is allowed to reselect the same frequency cell.

[0208] In a scenario where both cell access prohibition indication information for indicating a cell bar and IFRI for indicating whether a terminal is allowed to reselect a same-frequency cell are included, the cell access prohibition indication information for indicating a cell bar and IFRI for indicating whether a terminal is allowed to reselect a same-frequency cell can be indicated through the same signaling or through two different signaling instructions respectively.

[0209] For example, the IFRI included in the first cell access indication information may be an IFRI configured for a normal terminal, the IFRI included in the second cell access indication information may be an IFRI configured for a Redcap terminal, and the IFRI included in the third cell access indication information may be an IFRI configured for an eRedcap terminal.

[0210] In the embodiment of the present disclosure, the IFRI included in the third cell access indication information may be carried by at least one of the following information: MIB, SIB1, OSI, and DCI. For example, the independent IFRI configured for the eRedcap terminal may be carried by at least one of the following information: MIB, SIB1, OSI, and DCI.

[0211] In one implementation, in the embodiment of the present disclosure, the IFRI included in the third cell access indication information may be carried in SIB1.

[0212] On the one hand, in the embodiment of the present disclosure, the SIB1 carrying the IFRI included in the third cell access indication information is different from the SIB1 carrying the IFRI included in the second indication information. Among them, the SIB1 carrying the IFRI included in the third cell access indication information in the embodiment of the present disclosure may be the first SIB1 involved above. In one example, the first SIB1 is used to carry independent cell access prohibition indication information and independent IFRI configured for the eRedcap terminal.

[0213] On the other hand, in the embodiment of the present disclosure, the SIB1 carrying the IFRI included in the third cell access indication information is the same SIB1 as the SIB1 carrying the IFRI included in the second indication information. That is, in the embodiment of the present disclosure, the IFRI included in the third cell access indication information can be carried by the second SIB1.

[0214] In one implementation of the disclosed embodiment, when the first SIB1 is configured, the IFRI included in the third cell access indication information and the IFRI included in the second cell access indication information can be carried by the first SIB1. In one example, the IFRI configured for the eRedcap terminal and the IFRI configured for the Redcap terminal are both carried in the first SIB1.

[0215] In another implementation of the disclosed embodiment, the first SIB1 may not be configured. The IFRI of the first type of terminal, the second type of terminal, and the third type of terminal is indicated by the same SIB1. The SIB1 that carries the IFRI of the first type of terminal, the second type of terminal, and the third type of terminal may be the second SIB1 in the traditional technology, or may be the SIB1 indicated by the DCI. In a possible implementation, the first SIB1 may be a SIB1 specifically for the eRedcap terminal. Because the bandwidth supported by the eRedcap terminal is relatively small, the payload size of this single SIB1 may also be smaller.

[0216] In a possible implementation, the IFRI of the second type of terminal and the third type of terminal may be indicated by different fields of the same SIB1 or the same field. For example, the SIB1 includes an IFRI for indicating an eRedcap terminal and an IFRI for indicating a Redcap terminal. In a possible implementation, the IFRI of a Redcap terminal and the IFRI of an eRedcap terminal may be indicated by different values ​​of the same field of SIB1.

[0217] Further, in the embodiment of the present disclosure, when the third cell access indication information is carried by DCI, the DCI may be a DCI for indicating SIB1 (DCI for SIB1), or may be a DCI for indicating OSI (DCI for OSI).

[0218] Among them, in the embodiment of the present disclosure, the IFRI included in the third cell access indication information can correspond to the same receiving antenna or different receiving antennas. For example, the eRedcap terminals of 1RX and 2RX can be indicated by the same IFRI or by different IFRIs. For example, the bit indicating IFRI is 2 bits, wherein the high bit is used to indicate whether the eRedcap terminal of 1RX is allowed to reselect the same frequency cell, and the low bit is used to indicate whether the eRedcap terminal of 2RX is allowed to reselect the same frequency cell, or vice versa.

[0219] Further, in the embodiment of the present disclosure, when the third cell access indication information includes cell access prohibition indication information and IFRI, the cell access prohibition indication information and IFRI can be carried by different signalings. Of course, the cell access prohibition indication information and IFRI can also be carried by the same signaling.

[0220] In one embodiment, the IFRI indicated by the third cell access indication information is different from the IFRI indicated by the second cell access indication information and the first cell access indication information. In one example, the IFRI configured for the eRedcap terminal is independent of the IFRI configured for the normal terminal and the Redcap terminal. In another embodiment, the IFRI included in the third cell access indication information is the IFRI included in the second cell access indication information. In one example, the IFRI configured for the Redcap terminal is used as the IFRI of the eRedcap terminal to simultaneously indicate whether the Redcap terminal and the eRedcap terminal are allowed to reselect the same-frequency cell.

[0221] Among them, in the embodiment of the present disclosure, the following describes the implementation process of the terminal acquiring the IFRI in the third cell access indication information when the IFRI indicated by the third cell access indication information is independent of the IFRI indicated by the second cell access indication information.

[0222] Among them, in the embodiment of the present disclosure, when the eRedcap terminal obtains the IFRI included in the third cell access indication information, it can obtain the IFRI indicated by the third cell access indication information based on at least one of the cell access prohibition indication information indicated by the first cell access indication information, the cell access prohibition indication information indicated by the second cell access indication information, and the cell access prohibition indication information indicated by the third cell access indication information. For example, the embodiment of the present disclosure may include the following situation of obtaining the IFRI indicated by the third cell access indication information.

[0223] Scenario 1: Based on the third cell access indication information, the IFRI indicated by the third cell access indication information is obtained.

[0224] In a scenario where the third cell access indication information indicates both the cell bar and the IFRI, in response to the cell access prohibition indication information indicated by the third cell access indication information indicating that camping on the cell is not allowed, the IFRI indicated by the third cell access indication information is acquired.

[0225] Scenario 2: Based on the second cell access indication information, obtain the IFRI indicated by the third cell access indication information

[0226] In a scenario where the third cell access indication information indicates both the cell bar and the IFRI, on the one hand, in response to the cell access prohibition indication information indicated by the second cell access indication information indicating that the cell is not allowed to reside in the cell, and the IFRI indicated by the second cell access indication information is used to indicate that the same-frequency cell reselection is allowed, the IFRI indicated by the third cell access indication information is obtained. On the other hand, in response to the cell access prohibition indication information indicated by the second cell access indication information indicating that the cell is not allowed to reside in the cell, the IFRI indicated by the second cell access indication information is ignored, and the IFRI indicated by the third cell access indication information is obtained.

[0227] Scenario 3: Based on the first cell access indication information, the IFRI indicated by the third cell access indication information is obtained

[0228] In the scenario where the third cell access indication information indicates both the cell bar and the IFRI, on the one hand, in response to the cell access prohibition indication information indicated by the first cell access indication information indicating that the cell is not allowed to reside in the cell, and the IFRI indicated by the first cell access indication information is used to indicate that the same-frequency cell reselection is allowed, the IFRI indicated by the third cell access indication information is obtained. On the other hand, in response to the cell access prohibition indication information indicated by the first cell access indication information indicating that the cell is not allowed to reside in the cell, the IFRI indicated by the first cell access indication information is ignored, and the IFRI indicated by the third cell access indication information is obtained.

[0229] Scenario 4: Based on the first cell access indication information and the second cell access indication information, the IFRI indicated by the third cell access indication information is obtained

[0230] In the scenario where the third cell access indication information indicates both the cell bar and the IFRI, on the one hand, in response to the cell access prohibition indication information indicated by the first cell access indication information and the second cell access indication information indicating that the cell is not allowed to reside in the cell, and the IFRI indicated by the first cell access indication information and the second cell access indication information is used to indicate that the same-frequency cell reselection is allowed, the IFRI indicated by the third cell access indication information is obtained. On the other hand, in response to the cell access prohibition indication information indicated by the first cell access indication information and the second cell access indication information indicating that the cell is not allowed to reside in the cell, the IFRI indicated by the first cell access indication information and the second cell access indication information is ignored, and the IFRI indicated by the third cell access indication information is obtained.

[0231] In the disclosed embodiment, after the terminal obtains the third cell access indication information, it can perform cell access control and / or intra-frequency cell reselection based on the third cell access indication information.

[0232] In the embodiment of the present disclosure, performing cell access control based on the third cell access indication information may include the following situations:

[0233] Scenario 1: in response to the cell access prohibition indication information indicated by the third cell access indication information indicating that camping on the current cell is allowed, camping on the current cell.

[0234] Scenario 2: In response to the cell access prohibition indication information indicated by the third cell access indication information indicating that camping on the cell is not allowed, and the IFRI indicated by the third cell access indication information indicating that intra-frequency cell reselection is allowed, intra-frequency cell reselection is performed.

[0235] Scenario three: In response to the cell access prohibition indication information indicated by the third cell access indication information indicating that cell residence is not allowed, and the IFRI indicated by the third cell access indication information indicating that intra-frequency cell reselection is not allowed, the current cell is not resided and intra-frequency cell reselection is not performed.

[0236] Furthermore, in the embodiment of the present disclosure, when performing cell access control based on the third cell access indication information, the first cell access indication information and / or the second cell access indication information may be considered. For example, the following situations are included:

[0237] Scenario 1: In response to the cell access prohibition indication information indicated by the first cell access indication information indicating that cell residence is not allowed, and the IFRI indicated by the first cell access indication information is used to indicate that intra-frequency cell reselection is not allowed, the current cell is not resided and intra-frequency cell reselection is not performed.

[0238] Scenario 2: In response to the cell access prohibition indication information indicated by the second cell access indication information indicating that cell residence is not allowed, and the IFRI indicated by the second cell access indication information is used to indicate that intra-frequency cell reselection is not allowed, the current cell is not resided and intra-frequency cell reselection is not performed.

[0239] Scenario three: In response to the cell access prohibition indication information indicated by the first cell access indication information and the second cell access indication information indicating that cell residence is not allowed, and the IFRI indicated by the first cell access indication information and the second cell access indication information is used to indicate that intra-frequency cell reselection is not allowed, the current cell is not resided and intra-frequency cell reselection is not performed.

[0240] Based on the above method provided by the embodiment of the present disclosure, the first cell access indication information involved in the present disclosure is used to control the cell access of one or more types of terminals: first type terminals, second type terminals and third type terminals.

[0241] The second cell access indication information involved in the present disclosure is used to control the cell access of one or more types of terminals: second type terminals and third type terminals.

[0242] The third cell access indication information involved in the present disclosure is used to control the cell access of the third type of terminal.

[0243] In the embodiment of the present disclosure, when the terminal accesses a cell based on one or more of the first cell access indication information, the second cell access indication information and the third cell access indication information, it can perform adaptive cell access according to the capabilities of the terminal, thereby reducing the delay and energy consumption caused by the terminal's cell access.

[0244] Based on the same concept, an embodiment of the present disclosure also provides a cell access control method applied to a network device.

[0245] Figure 3 is a flow chart of a cell access control method according to an exemplary embodiment. Figure 3 As shown, the cell access control method is used in a network device. The cell access control method includes the following steps S21.

[0246] In step S21, cell access configuration information is sent.

[0247] The cell access configuration information is used to configure cell access indication information of different types of terminals. For example, the cell access indication information of at least one of the following types of terminals is configured: a first type of terminal, a second type of terminal, and a third type of terminal.

[0248] In one example, the cell access configuration information is used to configure first cell access indication information corresponding to a first type of terminal, second cell access indication information corresponding to a second type of terminal, and third cell access indication information corresponding to a third type of terminal. The capability of the first type of terminal is greater than that of the second type of terminal, and the capability of the second type of terminal is greater than that of the third type of terminal. In some possible implementations, the first type of terminal may be an ordinary terminal; the second type of terminal may be a Redcap terminal (or NR-lite for short); and the third type of terminal may be an eRedcap terminal.

[0249] In one example, the first cell access indication information may be the cell access indication information configured for a normal terminal in the MIB. The second cell access indication information may be the cell access indication information configured for a Redcap terminal in the MIB. The third cell access indication information may be independent cell access indication information configured for an eRedcap terminal, and the independent cell access indication information is different from the first cell access indication information and the second cell access indication information. Of course, in the disclosed embodiment, the first cell access indication information, the second cell access indication information, and the third cell access indication information may be different fields of the same message, or may be different messages; at the same time, the first cell access indication information, the second cell access indication information, and the third cell access indication information (for example, different values) may also be indicated by the same field of the same message; the specific implementation method is no longer limited here.

[0250] In one implementation, the third cell access indication information is carried in at least one of the following information: MIB, SIB1, OSI, and DCI.

[0251] In one implementation manner, SIB1 includes: a first SIB1 and a second SIB1.

[0252] The first SIB1 is different from the second SIB1. The first SIB1 is used to carry the cell access prohibition indication information indicated by the third cell access indication information. The second SIB1 is used to carry the cell access prohibition indication information indicated by the second cell access indication information.

[0253] In one implementation manner, the first cell access indication information, the second cell access indication information, and the third cell access indication information include cell access prohibition indication information (cell bar) for indicating whether a terminal of a type corresponding to the cell access indication information is allowed to reside in the cell. In one implementation manner of the embodiment of the present disclosure, the first cell access indication information, the second cell access indication information, and the third cell access indication information include cell access prohibition indication information (cell bar) for indicating whether a terminal of a type corresponding to the cell access indication information is allowed to reside in the cell.

[0254] In the embodiment of the present disclosure, only the third cell access indication information may be included; one or both of the first cell access indication information and the second cell access indication information may also be additionally included.

[0255] For example, the cell access prohibition indication information included in the first cell access indication information may be cell bar indication information configured for a normal terminal, and the first cell access indication information is used to indicate whether a first type of terminal is allowed to access the cell. The cell access prohibition indication information included in the second cell access indication information may be cell bar indication information configured for a Redcap terminal, and the second cell access indication information is used to indicate whether a second type of terminal is allowed to access the cell. The cell access prohibition indication information included in the third cell access indication information may be cell bar indication information configured for an eRedcap terminal, and the third cell access indication information is used to indicate whether a second type of terminal is allowed to access the cell. As mentioned above, the first cell access indication information, the second cell access indication information, and the third cell access indication information may be different fields of the same message, or may be different messages; at the same time, the first cell access indication information, the second cell access indication information, and the third cell access indication information (for example, different values) may also be indicated by the same field of the same message; the specific implementation method is no longer limited here. For example, if the cell access prohibition indication information included in the second cell access indication information may be cell bar indication information configured for Redcap terminals and cell bar indication information configured for eRedcap terminals, it may simultaneously indicate whether the cell allows Redcap terminals and eRedcap terminals to access.

[0256] In the embodiment of the present disclosure, the cell access prohibition indication information included in the third cell access indication information may be carried by at least one of the following information: MIB, SIB1, OSI, and DCI. For example, the independent cell bar indication information configured for the eRedcap terminal may be carried by at least one of the following information: MIB, SIB1, OSI, and DCI.

[0257] In one implementation, in the embodiment of the present disclosure, the cell access prohibition indication information included in the third cell access indication information may be carried in SIB1.

[0258] On the one hand, in the embodiment of the present disclosure, the SIB1 carrying the cell access prohibition indication information included in the third cell access indication information is different from the SIB1 carrying the cell access prohibition indication information included in the second indication information. Among them, for the convenience of description, the SIB1 carrying the cell access prohibition indication information included in the third cell access indication information is referred to as the first SIB1. The SIB1 carrying the cell access prohibition indication information included in the second indication information is referred to as the second SIB1. In one example, the first SIB1 is used to carry independent cell bar indication information configured for the eRedcap terminal. The second SIB1 is used to carry the cell bar indication information configured for the Redcap terminal. It can also be understood that the SIB1 configured by the network device in the embodiment of the present disclosure includes the first SIB1 and the second SIB1. In a possible implementation method, the first SIB1 can be a SIB1 specifically for the eRedcap terminal. Because the bandwidth supported by the eRedcap terminal is relatively small, the payload size of this separate SIB1 may also be smaller.

[0259] On the other hand, in the embodiment of the present disclosure, the SIB1 carrying the cell access prohibition indication information included in the third cell access indication information and the SIB1 carrying the cell access prohibition indication information included in the second indication information are the same SIB1.

[0260] In one implementation of the disclosed embodiment, when the first SIB1 is configured, the cell access prohibition indication information included in the second indication information can be carried in the first SIB. In one example, the cellbar indication information configured for the eRedcap terminal and the cell bar indication information configured for the Redcap terminal are both carried in the first SIB1.

[0261] In another implementation of the disclosed embodiment, the cell access prohibition indication information of the second type of terminal and the third type of terminal is indicated by the same SIB1. The SIB1 may be the second SIB1 in the conventional technology. In a possible implementation, the cell access prohibition indication information of the second type of terminal and the third type of terminal may be indicated by different fields of the same SIB1 or the same field. For example, the SIB1 includes a field for indicating the cell bar indication information configured for the eRedcap terminal, and a field for indicating the cell bar indication information configured for the Redcap terminal. In a possible implementation, the cellbar indication information configured for the Redcap terminal and the cell bar indication information configured for the eRedcap terminal may be indicated by different values ​​of the same field of SIB1.

[0262] Further, in the embodiment of the present disclosure, when the third cell access indication information is carried by DCI, the DCI may be a DCI for indicating SIB1 (DCI for SIB1), or may be a DCI for indicating OSI (DCI for OSI).

[0263] Among them, in the embodiment of the present disclosure, the cell access prohibition indication information included in the third cell access indication information can correspond to the same receiving antenna or to different receiving antennas. For example, the eRedcap terminals of 1RX and 2RX can be indicated by the same cell access prohibition indication information or by different cell access prohibition indication information. For example, the bit position indicating the cell access prohibition indication information is 2 bits, wherein the high bit position is used to indicate whether the eRedcap terminal of 1RX is allowed to access the cell, and the low bit position is used to indicate whether the eRedcap terminal of 2RX is allowed to access the cell, or vice versa.

[0264] In one implementation, the cell access prohibition indication information indicated by the third cell access indication information is different from the cell access prohibition indication information indicated by the second cell access indication information and the first cell access indication information. In one example, the cell bar indication information configured for the eRedcap terminal is independent of the cell bar indication information configured for the normal terminal and the Redcap terminal, that is: the cell access prohibition indication information for the eRedcap terminal is indicated by an independent cell bar indication information, and the cell access prohibition indication information for the normal terminal and the Redcap terminal is indicated by another cell bar indication information. In another implementation, the cell access prohibition indication information indicated by the third cell access indication information is the cell access prohibition indication information indicated by the second cell access indication information. In one example, the cell bar indication information configured for the Redcap terminal is used as the cell bar indication information of the eRedcap terminal to indicate whether the eRedcap terminal is allowed to access the cell. That is: the cell access prohibition indication information for the eRedcap terminal and the Redcap terminal is indicated by a cell bar indication information.

[0265] In one implementation, the first cell access indication information, the second cell access indication information, and the third cell access indication information in the disclosed embodiment include an IFRI for indicating whether the terminal is allowed to reselect the same-frequency cell. That is, the first cell access indication information, the second cell access indication information, and the third cell access indication information may include cell access prohibition indication information for indicating a cell bar, and may also include an IFRI for indicating whether the terminal is allowed to reselect the same-frequency cell, and may also include both cell access prohibition indication information for indicating a cell bar and an IFRI for indicating whether the terminal is allowed to reselect the same-frequency cell.

[0266] Similar to the aforementioned implementation, the IFRI of whether the terminal is allowed to reselect the same-frequency cell included in the first cell access indication information may be configured for a normal terminal, and the first cell access indication information is used to indicate whether the first type of terminal is allowed to reselect the same-frequency cell. The IFRI of whether the terminal is allowed to reselect the same-frequency cell included in the second cell access indication information may be configured for a Redcap terminal, and the second cell access indication information is used to indicate whether the second type of terminal is allowed to reselect the same-frequency cell. The IFRI of whether the terminal is allowed to reselect the same-frequency cell included in the third cell access indication information may be configured for an eRedcap terminal, and the third cell access indication information is used to indicate whether the third type of terminal is allowed to reselect the same-frequency cell.

[0267] In the embodiment of the present disclosure, only the third cell access indication information may be included; one or both of the first cell access indication information and the second cell access indication information may also be additionally included.

[0268] As mentioned above, the first cell access indication information, the second cell access indication information, and the third cell access indication information can be different fields of the same message, or different messages; at the same time, the first cell access indication information, the second cell access indication information, and the third cell access indication information (for example, different values) can also be indicated by the same field of the same message; the specific implementation method is no longer limited here. For example, if the IFRI included in the second cell access indication information indicating whether the terminal is allowed to reselect the same-frequency cell can be the cell bar indication information configured for the Redcap terminal and the cell bar indication information configured for the eRedcap terminal, it can simultaneously indicate whether the cell allows the Redcap terminal and the eRedcap terminal to access.

[0269] In the following implementation, the cell access prohibition indication information for indicating the cell bar and the IFRI for indicating whether the terminal is allowed to reselect the same frequency cell are used as an example for explanation. However, it can be understood by those skilled in the art that the following implementations can include only the IFRI for indicating whether the terminal is allowed to reselect the same frequency cell.

[0270] In a scenario where both cell access prohibition indication information for indicating a cell bar and IFRI for indicating whether a terminal is allowed to reselect a same-frequency cell are included, the cell access prohibition indication information for indicating a cell bar and IFRI for indicating whether a terminal is allowed to reselect a same-frequency cell can be indicated through the same signaling or through two different signaling instructions respectively.

[0271] For example, the IFRI included in the first cell access indication information may be an IFRI configured for a normal terminal, the IFRI included in the second cell access indication information may be an IFRI configured for a Redcap terminal, and the IFRI included in the third cell access indication information may be an IFRI configured for an eRedcap terminal.

[0272] In the embodiment of the present disclosure, the IFRI included in the third cell access indication information may be carried by at least one of the following information: MIB, SIB1, OSI, and DCI. For example, the independent IFRI configured for the eRedcap terminal may be carried by at least one of the following information: MIB, SIB1, OSI, and DCI.

[0273] In one implementation, in the embodiment of the present disclosure, the IFRI included in the third cell access indication information may be carried in SIB1.

[0274] On the one hand, in the embodiment of the present disclosure, the SIB1 carrying the IFRI included in the third cell access indication information is different from the SIB1 carrying the IFRI included in the second indication information. Among them, the SIB1 carrying the IFRI included in the third cell access indication information in the embodiment of the present disclosure may be the first SIB1 involved above. In one example, the first SIB1 is used to carry independent cell access prohibition indication information and independent IFRI configured for the eRedcap terminal.

[0275] On the other hand, in the embodiment of the present disclosure, the SIB1 carrying the IFRI included in the third cell access indication information is the same SIB1 as the SIB1 carrying the IFRI included in the second indication information. That is, in the embodiment of the present disclosure, the IFRI included in the third cell access indication information can be carried by the second SIB1.

[0276] In one implementation of the disclosed embodiment, when the first SIB1 is configured, the IFRI included in the third cell access indication information and the IFRI included in the second cell access indication information can be carried by the first SIB1. In one example, the IFRI configured for the eRedcap terminal and the IFRI configured for the Redcap terminal are both carried in the first SIB1.

[0277] In another implementation of the disclosed embodiment, the first SIB1 may not be configured. The IFRI of the first type of terminal, the second type of terminal, and the third type of terminal is indicated by the same SIB1. The SIB1 that carries the IFRI of the first type of terminal, the second type of terminal, and the third type of terminal may be the second SIB1 in the traditional technology, or may be the SIB1 indicated by the DCI. In a possible implementation, the first SIB1 may be a SIB1 specifically for the eRedcap terminal. Because the bandwidth supported by the eRedcap terminal is relatively small, the payload size of this single SIB1 may also be smaller.

[0278] In a possible implementation, the IFRI of the second type of terminal and the third type of terminal may be indicated by different fields of the same SIB1 or the same field. For example, the SIB1 includes an IFRI for indicating an eRedcap terminal and an IFRI for indicating a Redcap terminal. In a possible implementation, the IFRI of a Redcap terminal and the IFRI of an eRedcap terminal may be indicated by different values ​​of the same field of SIB1.

[0279] Further, in the embodiment of the present disclosure, when the third cell access indication information is carried by DCI, the DCI may be a DCI for indicating SIB1 (DCI for SIB1), or may be a DCI for indicating OSI (DCI for OSI).

[0280] Among them, in the embodiment of the present disclosure, the IFRI included in the third cell access indication information can correspond to the same receiving antenna or different receiving antennas. For example, the eRedcap terminals of 1RX and 2RX can be indicated by the same IFRI or by different IFRIs. For example, the bit indicating IFRI is 2 bits, wherein the high bit is used to indicate whether the eRedcap terminal of 1RX is allowed to reselect the same frequency cell, and the low bit is used to indicate whether the eRedcap terminal of 2RX is allowed to reselect the same frequency cell, or vice versa.

[0281] Further, in the embodiment of the present disclosure, when the third cell access indication information includes cell access prohibition indication information and IFRI, the cell access prohibition indication information and IFRI can be carried by different signalings. Of course, the cell access prohibition indication information and IFRI can also be carried by the same signaling.

[0282] In one embodiment, the IFRI indicated by the third cell access indication information is different from the IFRI indicated by the second cell access indication information and the first cell access indication information. In one example, the IFRI configured for the eRedcap terminal is independent of the IFRI configured for the normal terminal and the Redcap terminal. In another embodiment, the IFRI included in the third cell access indication information is the IFRI included in the second cell access indication information. In one example, the IFRI configured for the Redcap terminal is used as the IFRI of the eRedcap terminal to simultaneously indicate whether the Redcap terminal and the eRedcap terminal are allowed to reselect the same-frequency cell.

[0283] In one implementation manner, the cell access prohibition indication information or IFRI indicated by the third cell access indication information corresponds to the same receiving antenna or different receiving antennas.

[0284] In one implementation, the third cell access indication information includes cell access prohibition indication information and IFRI, and the cell access prohibition indication information and IFRI are carried by different signaling.

[0285] In the cell access control method provided by the embodiment of the present disclosure, the cell access configuration information configured by the network device includes first cell access indication information corresponding to the first type of terminal, second cell access indication information corresponding to the second type of terminal, and third cell access indication information corresponding to the third type of terminal, thereby realizing an indication of whether the terminal can access the cell according to the capability of the terminal, so as to balance the network load and avoid introducing unnecessary delay or energy consumption overhead when the terminal accesses the cell.

[0286] It is understandable that the cell access control method provided in the embodiment of the present disclosure is applicable to the process of realizing cell access control by the interaction between the network device and the terminal. Among them, the process of realizing cell access control by the interaction between the network device and the terminal is not described in detail in the embodiment of the present disclosure.

[0287] It should be noted that those skilled in the art can understand that the various implementation methods / embodiments involved in the embodiments of the present disclosure can be used in conjunction with the aforementioned embodiments or can be used independently. Whether used alone or in conjunction with the aforementioned embodiments, the implementation principle is similar. In the implementation of the present disclosure, some embodiments are described in terms of implementation methods used together. Of course, those skilled in the art can understand that such examples are not limitations of the embodiments of the present disclosure.

[0288] Based on the same concept, an embodiment of the present disclosure also provides a cell access control device.

[0289] It is understandable that the cell access control device provided in the embodiment of the present disclosure includes hardware structures and / or software modules corresponding to the execution of each function in order to realize the above functions. In combination with the units and algorithm steps of each example disclosed in the embodiment of the present disclosure, the embodiment of the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art may use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the technical solution of the embodiment of the present disclosure.

[0290] Figure 4 FIG. 1 is a block diagram of a cell access control device according to an exemplary embodiment. Figure 4 The cell access control device 100 is applied to a terminal and includes a processing unit 101 and an acquisition unit 102.

[0291] The processing unit 101 is configured to determine cell access configuration information, where the cell access configuration information is used to configure first cell access indication information corresponding to a first type of terminal, second cell access indication information corresponding to a second type of terminal, and third cell access indication information corresponding to a third type of terminal.

[0300] In one implementation, in response to the cell access prohibition indication information indicated by the third cell access indication information indicating that camping on the cell is not allowed, the acquisition unit 102 acquires the intra-frequency cell reselection flag indicated by the third cell access indication information.

[0301] In one implementation, in response to the cell access prohibition indication information indicated by the second cell access indication information indicating that the cell is not allowed to be camped on, and the intra-frequency cell reselection flag indicated by the second cell access indication information is used to indicate that intra-frequency cell reselection is allowed, the acquisition unit 102 acquires the intra-frequency cell reselection flag indicated by the third cell access indication information. Or

[0302] In response to the cell access prohibition indication information indicated by the second cell access indication information indicating that camping on the cell is not allowed, the acquisition unit 102 ignores the intra-frequency cell reselection flag indicated by the second cell access indication information, and acquires the intra-frequency cell reselection flag indicated by the third cell access indication information.

[0303] In one implementation, in response to the cell access prohibition indication information indicated by the first cell access indication information indicating that the cell is not allowed to stay in the cell, and the intra-frequency cell reselection flag indicated by the first cell access indication information is used to indicate that intra-frequency cell reselection is allowed, the acquisition unit 102 acquires the intra-frequency cell reselection flag indicated by the third cell access indication information.
