[0035] Please refer to Figure 1 , which shows a schematic structural diagram of a wireless communication system provided by an embodiment of the present disclosure. Figure 1 As shown, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include: several user equipments 110 and several base stations 120.

[0036] The user equipment 110 may be a device that provides voice and / or data connectivity to a user. The user equipment 110 may communicate with one or more core networks via a radio access network (RAN). The user equipment 110 may be an Internet of Things user device, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an Internet of Things user device. For example, the user equipment 110 may be a fixed, portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted device. For example, a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment. Alternatively, the user equipment 110 may be a device on an unmanned aerial vehicle.

[0038] Among them, the base station 120 can be an evolved base station (eNB) adopted in a 4G system. Alternatively, the base station 120 can also be a base station (gNB) adopting a centralized distributed architecture in a 5G system. When the base station 120 adopts a centralized distributed architecture, it usually includes a centralized unit (CU) and at least two distributed units (DU).

The embodiment of the present disclosure does not limit the specific implementation method of the base station 120.

[0039] A wireless connection can be established between the base station 120 and the user equipment 110 via a wireless air interface. In various implementations, the wireless air interface is a wireless air interface based on the fourth generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; or, the wireless air interface can also be a wireless air interface based on the next generation mobile communication network technology standard of 5G.

[0041] Here, the above user equipment can be considered as the terminal equipment in the following embodiments.

[0042] In some embodiments, the wireless communication system may further include a network management device 130 .

[0043] Several base stations 120 are respectively connected to a network management device 130. The network management device 130 may be a core network device in a wireless communication system. For example, the network management device 130 may be a mobility management entity (MME) in an evolved packet core (EPC). Alternatively, the network management device may be other core network devices, such as a serving gateway (SGW), a public data network gateway (PGW), a policy and charging rules function (PCRF), or a home subscriber server (HSS). The embodiments of the present disclosure do not limit the implementation form of the network management device 130.

[0044] To facilitate understanding by those skilled in the art, the embodiments of the present disclosure list multiple implementation methods to clearly illustrate the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art will understand that the multiple embodiments provided in the embodiments of the present disclosure can be implemented individually, or can be implemented together with the methods of other embodiments in the embodiments of the present disclosure, or can be implemented together with some methods in other related technologies individually or in combination; the embodiments of the present disclosure do not limit this.

[0045] In order to better understand the technical solutions described in any embodiment of the present disclosure, first, a partial description of cell access or cell reselection in related technologies is given:

[0046] In one embodiment, the MIB includes a cell barring flag and / or a cell reselection flag; wherein the cell barring flag is used to indicate whether access to the cell is allowed; and the cell reselection flag is used to indicate whether cell reselection is possible. Here, the cell reselection flag includes an intra-frequency reselection (IFRI) flag; the intra-frequency reselection flag is used to indicate whether intra-frequency cell reselection is possible. Here, the cell barring flag and cell reselection flag included in the MIB are for any type of UE.

[0047] In one embodiment, the UE may be: a Radio Resource Control (RRC) idle state UE, an RRC inactive state UE, or an RRC connected state UE. The UE stores the acquired UE; the UE determines that the cell prohibition flag in the MIB indicates prohibition, and determines that the UE is prohibited from accessing the cell; if the UE determines that the same-frequency reselection flag indicates that reselection is not allowed, it is determined that the UE is not allowed to reselect to a cell with the same frequency as the prohibited cell; if the UE determines that the same-frequency reselection flag indicates that reselection is allowed, it is determined that the UE is allowed to reselect to a cell with the same frequency as the prohibited cell. Here, the UE may also receive at least one of the system frame number, SIB1 configured by the Physical Downlink Control Channel (PDCCH), subcarrier spacing, subcarrier offset value, and modulation reference signal (DMRS)-A type-position information.

[0048] In one embodiment, the MIB includes two indication bits, which respectively indicate a cell barring flag or a cell reselection flag; the MIB may also include a reserved bit. For example, this can be implemented by the following code:

[0049]

[0050] In one embodiment, a signaling (Mg) identifier indicating enablement or disablement can be configured by the radio access network (RAN2); this can be achieved by specifying a two-step random access (RACH) procedure. A separate indication is specified in SIB1 to prohibit RedCap UEs with 1 antenna (RX) or 2 antennas (RX); RedCap is indicated by a specific IFRI in SIB1; the IFRI indicating the RedCap UE in SIB1 is indicated separately for 1 antenna or 2 antennas. In one embodiment, if there is a specific IFRI indicating RedCap in the broadcast system information (SI), it is considered that the UE does not support RedCap. In one embodiment, the RedCap UE applies the existing cell barred (cellBarred) field in the MIB. Here, the RedCap UE is a low-cost and low-load UE, such as various types of sensors, monitoring equipment, wearable devices, etc.

[0051] In one embodiment, a cell barring indication indicating a RedCap UE is included in SIB1; however, SIB1 only includes the IFRI identifier for the RedCap UE. Here, it can be understood that in the prior art, the cell barring identifier for the MIB is for all users, for example, it is also applicable to enhanced mobile broadband (eMBB) devices.

[0052] like Figure 2As shown, an embodiment of the present disclosure provides a cell reselection method, which is performed by a specific type of UE, including:

[0053] Step S21: In response to the cell barring flag indicating access barring, determining the execution of a cell reselection operation according to the cell reselection flag in the MIB and / or the cell reselection flag for a specific type of UE in the SIB.

[0054] The methods provided in the embodiments of the present disclosure are performed by a specific type of UE; this specific type of UE may be, but is not limited to, a RedCap UE. Here, this specific type of UE may be, but is not limited to: a relatively low-end UE; for example, various sensor terminals used in industry, such as pressure sensors, humidity sensors, or motion sensors; monitoring equipment used in the monitoring field; various wearable devices, such as smart watches; and so on. Here, the specific type of UE may be in RRC connected state, RRC inactive state, or RRC idle state.

[0055] The present disclosure provides a cell reselection method performed by a specific type of UE, including obtaining system information. Here, the system information includes, but is not limited to, MIB and / or SIB. The specific type of UE may receive system information sent by a network device or obtain system information stored in the specific type of UE. The network device may be an access network device or a core network device. For example, the access network device includes a base station; the core network device includes a mobility management entity.

[0056] In some embodiments of the present disclosure, the SIB includes: SIB 1. Of course, in other embodiments, the SIB may also be a SIB in other formats, such as SIB 2 or SIB x, where x is an integer greater than 1.

[0057] In one embodiment, the MIB includes a cell barring flag. The cell barring flag in the MIB can be specific to various types of UEs. For example, the cell barring flag in the MIB may target a computer, server, mobile phone, wearable device, or multimedia device. Another example is a relatively high-end eMBB UE or a relatively low-end RedCap UE.

[0058] In another embodiment, the SIB includes a cell barring flag. Here, the cell barring flag of the SIB may be for a specific type of UE; for example, the UE targeted by the cell barring flag of the SIB is a relatively low-end RedCap UE.

[0059] Here, the cell prohibition flag may indicate prohibition of access or permission of access. For example, if the cell prohibition flag is "0", it indicates prohibition of access; if the cell prohibition flag is "1", it indicates permission of access.

[0060] Here, the cell barring flag is used to indicate that a UE is prohibited from accessing a cell or to indicate that a UE is allowed to access a cell. In one embodiment, the cell barring flag is used to indicate that a specific type of UE is prohibited from accessing a cell that sends the cell barring flag or to indicate that a specific type of UE is allowed to access a cell that sends the cell barring flag.

[0061] In one embodiment, if a specific type of UE determines that a cell barring flag in the MIB indicates that access is prohibited, then the execution of a cell reselection operation is determined based on the cell reselection flag in the MIB and / or the cell reselection flag for the specific type of UE in the SIB. Thus, in this embodiment, if the specific type of UE indicates that access is prohibited based on the cell barring flag in the MIB, it can be determined that the specific type of UE is prohibited from accessing the cell.

[0062] In another embodiment, a specific type of UE determines that the MIB cell prohibition flag indicates that access is allowed and the SIB cell prohibition flag indicates that access is prohibited, and determines the execution of the cell reselection operation based on the MIB cell reselection flag and / or the cell reselection flag for the specific type of UE in the SIB. In this way, in this embodiment, when the cell prohibition flag in the MIB indicates that access is allowed, the specific type of UE can further determine whether the specific type of UE is prohibited from accessing the cell based on the cell prohibition flag in the SIB; if the cell prohibition flag in the SIB indicates that access is prohibited, it is determined that the specific type of UE is prohibited from accessing the cell.

[0063] In one embodiment, the MIB includes a cell reselection flag. Here, the MIB cell reselection flag is a cell reselection flag for various types of UEs. For example, the MIB cell reselection flag may target a UE such as a computer, server, mobile phone, wearable device, or multimedia device. Another example is the MIB cell barring flag, which may target a relatively high-end eMBB UE or a relatively low-end RedCap UE.

[0064] In another embodiment, the SIB includes a cell reselection flag. Here, the cell reselection flag of the SIB is targeted at a specific type of UE; for example, the cell barring flag of the SIB is targeted at a relatively low-end RedCap UE.

[0065] Here, the cell reselection flag may indicate whether cell reselection is allowed or not. For example, if the cell reselection flag is "0", it indicates that a specific type of UE is not allowed to reselect a neighboring cell; if the cell reselection flag is "1", it indicates that a specific type of UE is allowed to reselect a neighboring cell.

[0066] Here, the cell reselection flag is used to indicate that the UE is allowed to reselect a cell or that the UE is not allowed to reselect a cell. In one embodiment, the cell reselection flag is used to indicate that a specific type of UE is allowed to reselect or is prohibited from accessing a neighboring cell of the cell, or to indicate that a specific type of UE is not allowed to reselect or is prohibited from accessing a neighboring cell of the cell.

[0067] In one embodiment, the cell reselection identifier includes: an intra-frequency reselection identifier. Here, the intra-frequency reselection identifier may indicate whether reselection of an intra-frequency cell is allowed or not. For example, if the intra-frequency reselection identifier is "0", it indicates that a specific type of UE is not allowed to reselect other cells with the same frequency as the cell to which access is prohibited; if the intra-frequency reselection identifier is "1", it indicates that a specific type of UE is allowed to reselect other cells with the same frequency as the cell to which access is prohibited. Here, other cells may refer to neighboring cells with the same frequency, or may refer to intra-frequency cells other than cells to which access is prohibited.

[0068] In one embodiment, the cell barring flag and the cell reselection flag of the MIB can be indicated by one or more predetermined bits of the MIB. Here, the MIB cell reselection flag can be a cell reselection flag for various types of UEs or a cell reselection flag for a specific type of UE.

[0069] In another embodiment, the cell barring flag of the SIB and the cell reselection flag for a specific type of UE may be indicated by one or more predetermined bits of the MIB respectively.

[0070] In one embodiment, determining whether to perform a cell reselection operation according to a cell reselection identifier in the MIB and / or a cell reselection identifier for a specific type of UE in the SIB includes one of the following:

[0071] Determine the execution of the cell reselection operation according to the cell reselection flag of the MIB;

[0072] Determine the execution of the cell reselection operation based on the cell reselection identifier for the specific type of UE in the SIB;

[0073] The execution of the cell reselection operation is determined according to the cell reselection identifier of the MIB and the cell reselection identifier for a specific type of UE in the SIB.

[0074] In one embodiment, determining the execution of the cell reselection operation in step S21 may refer to determining whether to perform cell reselection.

[0075] In one embodiment, determining the execution of the cell reselection operation includes one of the following:

[0076] Determine to perform a cell reselection operation;

[0077] Determine not to perform a cell reselection operation.

[0078] In the embodiments of the present disclosure, a specific type of UE determines that it is prohibited from accessing a cell using a cell barring flag, and determines the execution of a cell reselection operation based on a cell reselection flag in the MIB and / or a cell reselection flag for the specific type of UE in the SIB. In this way, when a specific type of UE is prohibited from accessing a cell by a cell barring flag, the execution of a cell reselection operation can be accurately determined based on the cell reselection flag in the MIB and / or the cell reselection flag for the specific type of UE in the SIB, so that the specific type of UE can accurately determine whether it can reselect a cell for access.

[0079] In the embodiment of the present disclosure, if the cell reselection flag is an intra-frequency reselection flag, a specific type of UE can accurately determine whether it can reselect and access other cells on the same frequency as the access-prohibited cell.

[0080] It should be noted that those skilled in the art will understand that the method provided in the embodiments of the present disclosure may be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0081] In some embodiments, step S21 includes one of the following:

[0082] In response to the cell prohibition flag of the MIB indicating prohibition of access, determining execution of a cell reselection operation according to the cell reselection flag of the MIB;

[0083] In response to the cell barring flag in the MIB indicating access barring, determining execution of a cell reselection operation based on a cell reselection flag for a specific type of UE in the SIB;

[0084] In response to the cell barring flag in the MIB indicating access barring, the execution of the cell reselection operation is determined according to the cell reselection flag in the MIB and the cell reselection flag for the specific type of UE in the SIB.

[0085] In some embodiments of the present disclosure, the specific type of UE prohibiting access in response to a cell prohibition flag indication, means that the specific type of UE prohibiting access in response to a cell prohibition flag indication of the MIB.

[0086] In some embodiments of the present disclosure, the cell prohibition flag of the MIB is the cell prohibition flag of the MIB in step S21; the cell reselection flag of the MIB is the cell reselection flag of the MIB in step S21; the cell reselection flag for a specific type of UE in the SIB is the cell reselection flag for a specific type of UE in the SIB in step S21.

[0087] like Figure 3 As shown, an embodiment of the present disclosure provides a cell reselection method, which is performed by a specific type of UE and may include:

[0088] Step S31: In response to the cell prohibition flag of the MIB indicating prohibition of access, the execution of the cell reselection operation is determined according to the cell reselection flag of the MIB.

[0089] Exemplarily, the specific type of UE determines that the cell prohibition flag of the MIB indicates that access is prohibited, and if it is determined that the cell reselection flag of the MIB indicates that reselection is allowed, determines to perform a cell reselection operation.

[0090] Exemplarily, the specific type of UE determines that the cell prohibition flag of the MIB indicates that access is prohibited, and if it is determined that the cell reselection flag of the MIB indicates that reselection is not allowed, it is determined not to perform the cell reselection operation.

[0091] Exemplarily, the specific type of UE determines that the cell prohibition flag of the MIB indicates that access is prohibited, and if it is determined that the intra-frequency reselection flag of the MIB indicates that reselection is allowed, it determines to perform the intra-frequency cell reselection operation.

[0092] Exemplarily, the specific type of UE determines that the cell prohibition flag of the MIB indicates that access is prohibited. If it is determined that the intra-frequency reselection flag of the MIB indicates that reselection is not allowed, it is determined not to perform the intra-frequency cell reselection operation.

[0093] In an embodiment of the present disclosure, if a specific type of UE indicates that access is prohibited based on a cell prohibition flag in the MIB, it is determined that the specific type of UE is prohibited from accessing the cell; then, based on the cell reselection flag in the MIB, it is determined that a cell reselection operation for the specific type of UE is performed. In this way, when it is determined that the cell prohibition flag in the MIB indicates that access is prohibited for the specific type of UE, cell reselection for the specific type of UE is performed based on the cell reselection flag in the MIB; in this way, cell reselection for the specific type of UE can be achieved solely through this information in the MIB, thereby improving the utilization of the MIB and reducing the latency of the cell reselection operation because there is no need to check the SIB.

[0094] like Figure 4 As shown, an embodiment of the present disclosure provides a cell reselection method, which is performed by a specific type of UE and may include:

[0095] Step S41: In response to the cell barring flag in the MIB indicating access barring, the execution of the cell reselection operation is determined according to the cell reselection flag for the specific type of UE in the SIB.

[0096] Exemplarily, the specific type of UE determines that the cell prohibition flag of the MIB indicates that access is prohibited. If it is determined that the cell reselection flag for the specific type of UE in the SIB indicates that reselection is allowed, it is determined to perform a cell reselection operation.

[0097] Exemplarily, the specific type of UE determines that the cell prohibition flag of the MIB indicates that access is prohibited. If it is determined that the cell reselection flag for the specific type of UE in the SIB indicates that reselection is not allowed, it is determined not to perform the cell reselection operation.

[0098] Exemplarily, the specific type of UE determines that the cell prohibition flag of the MIB indicates that access is prohibited. If it is determined that the intra-frequency reselection flag for the specific type of UE in the SIB indicates that reselection is allowed, it is determined to perform the intra-frequency cell reselection operation.

[0099] Exemplarily, the specific type of UE determines that the cell prohibition flag of the MIB indicates that access is prohibited. If it is determined that the intra-frequency reselection flag for the specific type of UE in the SIB indicates that reselection is not allowed, it is determined not to perform the intra-frequency cell reselection operation.

[0100] In an embodiment of the present disclosure, if a specific type of UE indicates access prohibition based on a cell prohibition indicator in the MIB, it is determined that the specific type of UE is prohibited from accessing the cell; and based on the cell reselection indicator for the specific type of UE in the SIB, the execution of the cell reselection operation for the specific type of UE is determined. This can accurately implement the cell reselection operation for the specific type of UE, so that the specific type of UE can accurately know whether to perform cell reselection; and provides another cell reselection method that can adapt to more application scenarios of performing cell reselection when access prohibition is indicated by the cell prohibition indicator in the MIB.

[0101] like Figure 5 As shown, an embodiment of the present disclosure provides a cell reselection method, which is performed by a specific type of UE and may include:

[0102] Step S51: In response to the cell barring flag in the MIB indicating access barring, the execution of the cell reselection operation is determined according to the cell reselection flag in the MIB and the cell reselection flag for a specific type of UE in the SIB.

[0103] In some embodiments, determining the execution of the cell reselection operation based on the cell reselection identifier of the MIB and the cell reselection identifier for a specific type of UE in the SIB includes one of the following:

[0104] In response to the cell reselection flag of the MIB indicating that cell reselection is not allowed, determining not to perform cell reselection;

[0105] In response to the cell reselection flag of the MIB indicating that cell reselection is allowed, the execution of the cell reselection operation is determined according to the cell reselection flag for the specific type of UE in the SIB.

[0106] like Figure 6 As shown, an embodiment of the present disclosure provides a cell reselection method, which is performed by a specific type of UE and may include:

[0107] Step S61: In response to the cell reselection flag in the MIB indicating that cell reselection is not allowed, determining not to perform cell reselection; or, in response to the cell reselection flag in the MIB indicating that cell reselection is allowed, determining to perform the cell reselection operation according to the cell reselection flag for the specific type of UE in the SIB.

[0108] Here, the cell reselection flag includes: a same-frequency reselection flag.

[0109] Exemplarily, in response to the cell prohibition flag of the MIB indicating access prohibition, if it is determined that the cell reselection flag of the MIB indicates that cell reselection is not allowed, the specific type of UE determines not to perform cell reselection.

[0110] Exemplarily, the specific type of UE responds to the MIB cell prohibition flag indicating access prohibition. If it is determined that the MIB cell reselection flag indicates that cell reselection is allowed, the execution of the cell reselection operation is determined according to the SIB cell reselection flag for the specific type of UE.

[0111] Here, if the cell prohibition flag in the MIB indicates that access is prohibited and the cell reselection flag in the MIB indicates that cell reselection is not allowed, then it is not necessary to obtain the SIB, and it can be directly determined that the specific type of UE does not perform cell reselection. If the cell prohibition flag in the MIB indicates that access is prohibited, but the cell reselection flag in the MIB indicates that cell reselection is not allowed; then it can be further determined whether to perform the cell reselection operation based on the indication of the cell reselection flag specifically for the specific type of UE in the SIB.

[0112] In some embodiments, determining whether to perform a cell reselection operation according to a cell reselection identifier for a specific type of UE in an SIB includes one of the following:

[0113] In response to a cell reselection flag for a specific type of UE in an SIB indicating that cell reselection is permitted, determining to perform a cell reselection operation;

[0114] In response to a cell reselection flag for a specific type of UE in the SIB indicating that cell reselection is not allowed, determining not to perform a cell reselection operation.

[0115] The present disclosure provides a cell reselection method, which is performed by a specific type of UE and may include: in response to a cell reselection identifier for the specific type of UE in an SIB indicating that cell reselection is allowed, determining to perform a cell reselection operation;

[0116] An embodiment of the present disclosure provides a cell reselection method, which is performed by a specific type of UE and may include: in response to a cell reselection identifier for the specific type of UE in an SIB indicating that cell reselection is not allowed, determining not to perform a cell reselection operation.

[0117] Exemplarily, a specific type of UE determines that the cell prohibition flag of the MIB indicates that access to the cell is prohibited and determines that the cell reselection flag of the MIB indicates that cell reselection is allowed; if the cell reselection flag for the specific type of UE in the SIB indicates that cell reselection is allowed, it is determined that the cell reselection operation is performed; if the cell reselection flag for the specific type of UE in the SIB indicates that cell reselection is not allowed, it is determined that the cell reselection operation is not performed.

[0118] In this way, the embodiments of the present disclosure can also combine the cell reselection identifier of the MIB and the cell reselection identifier for a specific type of UE in the SIB to determine whether a specific type of UE performs a cell reselection operation; thus providing more cell reselection methods when the cell prohibition identifier of the MIB indicates that a specific type of UE is prohibited from access, so as to adapt to more application scenarios.

[0119] It should be noted that those skilled in the art will understand that the method provided in the embodiments of the present disclosure may be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0120] In some embodiments, the cell reselection identifier of the MIB is: a cell reselection identifier for a specific type of UE. Here, the reserved bit of the MIB can carry the cell reselection identifier for the specific type of UE. Exemplarily, one or more reserved bits of the MIB carry the cell reselection identifier for the specific type of UE. Exemplarily, one or more predetermined bits of the MIB carry the cell reselection identifier; and one or more reserved bits of the MIB carry the cell reselection identifier for the specific type of UE.

[0121] In some embodiments, determining the execution of the cell reselection operation according to the cell reselection identifier of the MIB and / or the cell reselection identifier for a specific type of UE in the SIB includes one of the following:

[0122] In response to the cell reselection identifier for the specific type of UE not being configured in the SIB, determining execution of the cell reselection operation based on the cell reselection identifier for the specific type of UE in the MIB;

[0123] In response to a cell reselection identifier for a specific type of UE configured in the SIB, determining execution of a cell reselection operation based on the cell reselection identifier for the specific type of UE in the MIB or the cell reselection identifier for the specific type of UE in the SIB;

[0124] In response to not acquiring the SIB, determining to perform a cell reselection operation based on a cell reselection identifier for a specific type of UE in the MIB.

[0125] In some embodiments of the present disclosure, a specific type of UE prohibits access in response to a cell prohibition indicator indicating prohibited access, which means that the specific type of UE prohibits access in response to the cell prohibition indicator indication of the MIB, or the specific type of UE allows access in response to the cell prohibition indicator indication of the MIB and prohibits access in response to the cell prohibition indicator indication of the SIB.

[0126] In some embodiments of the present disclosure, the cell reselection identifier may be the cell reselection identifier in step S21.

[0127] like Figure 7 As shown, an embodiment of the present disclosure provides a cell reselection method, which is performed by a specific type of UE, including:

[0128] Step S71: In response to the fact that the cell reselection identifier for the specific type of UE is not configured in the SIB, the execution of the cell reselection operation is determined based on the cell reselection identifier for the specific type of UE in the MIB; or, in response to the fact that the cell reselection identifier for the specific type of UE is configured in the SIB, the execution of the cell reselection operation is determined based on the cell reselection identifier for the specific type of UE in the MIB or the cell reselection identifier for the specific type of UE in the SIB; or, in response to the SIB not being obtained, the execution of the cell reselection operation is determined based on the cell reselection identifier for the specific type of UE in the MIB.

[0129] Here, when a specific type of UE is prohibited from access, if it is determined that the SIB has not been obtained, the execution of the cell reselection operation is determined directly based on the cell reselection identifier for the specific type of UE in the MIB. Exemplarily, in response to the cell prohibition identifier in the MIB indicating that access is prohibited, if it is determined that the cell reselection identifier in the MIB for the specific type of UE indicates that reselection is allowed, the cell reselection operation is determined to be performed; if it is determined that the cell reselection identifier in the MIB for the specific type of UE indicates that reselection is not allowed, the cell reselection operation is determined not to be performed.

[0130] In this way, the embodiment of the present disclosure can implement cell reselection for a specific type of UE based on the cell barring flag in the MIB and the cell reselection flag for the specific type of UE even when the SIB is not received. Furthermore, the utilization rate of the MIB can be improved.

[0131] Here, when a specific type of UE is prohibited from accessing, if the cell reselection identifier for the specific type of UE is not configured in the SIB, the execution of the cell reselection operation can be directly determined based on the cell reselection identifier for the specific type of UE in the MIB.

[0132] In some embodiments, step S21 includes at least one of the following:

[0133] In response to a cell barring flag in the MIB indicating access barring, determining execution of a cell reselection operation based on a cell reselection flag for a specific type of UE in the MIB;

[0134] In response to the cell barring flag of the MIB indicating that access is allowed and the cell barring flag of the SIB indicating that access is prohibited, the execution of the cell reselection operation is determined based on the cell reselection flag for the specific type of UE in the MIB.

[0135] An embodiment of the present disclosure provides a cell reselection method, which is performed by a specific type of UE and may include: in response to a cell prohibition flag in the MIB indicating prohibition of access, determining the execution of a cell reselection operation based on a cell reselection flag for the specific type of UE in the MIB.

[0136] An embodiment of the present disclosure provides a cell reselection method, which is performed by a specific type of UE and may include: in response to a cell prohibition flag of the MIB indicating that access is allowed and a cell prohibition flag of the SIB indicating that access is prohibited, determining the execution of the cell reselection operation based on the cell reselection flag for the specific type of UE in the MIB.

[0137] Here, based on the cell reselection identifier for a specific type of UE in the MIB, determining whether to execute the cell reselection operation includes: if the cell reselection identifier for the specific type of UE in the MIB indicates that reselection is allowed, determining to execute the cell reselection operation; or if the cell reselection identifier for the specific type of UE in the MIB indicates that reselection is not allowed, determining not to execute the cell reselection operation.

[0138] Thus, in the embodiments of the present disclosure, whether the cell barring flag in the MIB indicates that a specific type of UE is prohibited from accessing, or the cell barring flag in the SIB indicates that a specific type of UE is prohibited from accessing, the execution of the cell reselection operation can be determined based on the cell reselection flag for the specific type of UE in the MIB. This can also improve the utilization rate of the MIB.

[0139] Here, when a specific type of UE is prohibited from access, if a cell reselection identifier for the specific type of UE is configured in the SIB, the execution of the cell reselection operation can be determined based on the cell reselection identifier for the specific type of UE in the MIB or the cell reselection identifier for the specific type of UE in the SIB.

[0140] In some embodiments, step S21 includes at least one of the following:

[0141] In response to a cell barring flag in the MIB indicating access barring, determining execution of a cell reselection operation based on a cell reselection flag for a specific type of UE in the MIB;

[0142] In response to the cell barring flag of the MIB indicating that access is allowed and the cell barring flag of the SIB indicating that access is prohibited, the execution of the cell reselection operation is determined based on the cell reselection flag for the specific type of UE in the SIB.

[0143] The present disclosure provides a cell reselection method, which is performed by a specific type of UE and may include: responding to a cell prohibition flag in the MIB indicating prohibition of access, determining the execution of a cell reselection operation based on a cell reselection flag for the specific type of UE in the MIB;

[0144] An embodiment of the present disclosure provides a cell reselection method, which is performed by a specific type of UE and may include: in response to a cell prohibition flag of the MIB indicating that access is allowed and a cell prohibition flag of the SIB indicating that access is prohibited, determining the execution of the cell reselection operation based on the cell reselection flag for the specific type of UE in the SIB.

[0145] Here, based on the cell reselection identifier for the specific type of UE in the SIB, the execution of the cell reselection operation is determined, including: if the cell reselection identifier for the specific type of UE in the SIB indicates that reselection is allowed, determining to perform the cell reselection operation; if the cell reselection identifier for the specific type of UE in the SIB indicates that reselection is not allowed, determining not to perform the cell reselection operation.

[0146] Thus, in the embodiments of the present disclosure, if the cell barring flag in the MIB indicates that a specific type of UE is prohibited from access, the execution of a cell reselection operation can be determined based on the cell reselection flag for the specific type in the MIB; or if the cell barring flag in the SIB indicates that a cell reselection flag for the specific type of UE is used, the execution of a cell reselection operation can be determined. In this way, different cell reselection operation methods are provided for different access prohibition scenarios for specific types of UEs, thereby being applicable to more application scenarios.
