[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 202410930586.5, filed in China on July 11, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of communication technology, specifically relating to a communication operation execution method, apparatus, terminal, and network-side equipment. Background Technology

[0004] In related technologies, when a terminal determines whether a first cell can be considered an acceptable cell, if the terminal considers the first cell as a prohibited cell based on the first indication information broadcast by the first cell, then the terminal determines whether the first cell is acceptable only based on a preset specific indication. An acceptable cell refers to a cell where the terminal can camp and obtain limited service. However, using the preset specific indication to determine whether the first cell is acceptable may lead to the misclassification of cells that do not match the terminal, resulting in a higher probability of misjudgment when the terminal determines an acceptable cell.

[0066] For ease of understanding, the following explains some aspects of the embodiments of this application:

[0067] 1. Suitable Cell

[0068] A suitable cell is one in which a user equipment (UE, i.e., a terminal) can camp and obtain normal service. A suitable cell must meet at least the following characteristics (i.e., the criteria for determining a suitable cell):

[0069] The cell broadcasts the identifier of at least one of the following Public Land Mobile Networks (PLMNs) for the UE: the PLMN selected by the UE, the PLMN registered by the UE, or a PLMN in the Equivalent PLMN list;

[0070] The cell meets the cell selection criteria in 3GPP TS36.304 or 3GPP TS38.304;

[0071] There is no ban on staying in the community.

[0072] The tracking area (TA) information broadcast by the cell does not belong to the prohibited TA areas (list of "Forbidden Tracking Areas").

[0073] In this application embodiment, "cell is prohibited", "cell is prohibited", "cell is prohibited from residing" and "cell is barred" have the same meaning.

[0074] 2. Cell bar sign indicating no entry / exit in the residential area

[0075] In certain situations, to prevent a UE from accessing or camping on a cell, the cell may broadcast a cell bar indication in the system information (in LTE systems, the cell bar indication is located in SIB1, and the IE is cellBarred; in NR systems, the cell bar indication is located in MIB, and the IE is cellBarred). If the UE reads the system information and finds that the cellBarred IE is set to barred, the UE will avoid selecting or reselecting to that cell for a future period of time (the length of which is a preset value).

[0076] 3. Considered a Cell bar

[0077] In NR systems, besides the Master Information Block (MIB) indicating a cell is barred via the IE cellBarred indicator, the UE can also consider the first cell as barred based on system information broadcast by the first cell. Examples of considering the first cell as barred are as follows:

[0078] A. When the system information broadcast by the first cell does not carry the Tracking Area Code (TAC) corresponding to the PLMN associated with the UE, the UE will regard the first cell as a barred cell;

[0079] (a) The system information broadcast by the first cell can carry multiple PLMNs, such as three PLMNs. The cell can broadcast the TAC corresponding to one of the PLMNs (the first PLMN); it does not broadcast the TACs corresponding to the other two PLMNs (the second and third PLMNs).

[0080] (b) The PLMN associated with the UE includes any one of the following PLMNs: the PLMN selected by the UE, the PLMN registered by the UE, and the PLMN in the Equivalent PLMN list. If the PLMN associated with UE A does not contain the first PLMN, but contains the second, third, and fourth PLMNs (wherein the identifier of the fourth PLMN is not carried in the system information broadcast by the first cell), then UE A considers the first cell as a barred cell (the system information broadcast by the first cell does not contain the TAC corresponding to any of the four PLMNs associated with UE A); if the PLMN associated with UE B contains the first PLMN, then UE B determines that the system information broadcast by the first cell contains the TAC corresponding to at least one PLMN associated with UE B.

[0081] B. When the system information broadcast by the first cell carries IE cellBarred-RedCap1Rx and is set to "barred", if the UE is a UE that only supports the Reduced Capability (RedCap) of 1 Receiver Antenna (RX), it will regard the first cell as a barred cell.

[0082] C. When the system information broadcast by the first cell carries IE cellBarred2RxXR, if the UE is a 2RX XR UE, it will regard the first cell as a barred cell, etc.

[0083] It should be noted that a UE determines whether it is barred by the current cell based on all applicable bar indications (e.g., for RedCap UEs that only support 1Rx, applicable bar indications include: cellBarred-RedCap1Rx IE in the System Information Block (SIB), Cellbar IE in the MIB, the PLMN identifier associated with the UE broadcast in the SIB and the corresponding TAC, etc.). When any bar indication indicates that the UE is barred, the UE considers itself to be barred; when all bar indications indicate that the UE is not barred or do not indicate that the UE is barred, the UE considers itself not barred.

[0084] It should be noted that bar indications can take various forms. For example, CellBar in the MIB has two possible values: the first indicates that it is disabled, and the second indicates that it is not disabled (notBarred). CellBarred2RxXR is an optional Information Element (IE) in the SIB. When it is carried in the SIB, it indicates that the 2RX XR UE is barred; when it is not carried in the SIB, it indicates that the 2RX XR UE is not barred. This application does not limit the form of bar indication.

[0085] 4. Acceptable cell

[0086] An acceptable cell is a cell in which a UE can camp and receive limited services (initiating emergency calls, receiving Earthquake and Tsunami Warning System (ETWS) and Commercial Mobile Alert Service (CMAS)). These cells meet the following minimum requirements for initiating emergency calls and receiving ETWS and CMAS (i.e., the criteria for determining an acceptable cell):

[0087] There are no restrictions on bar stays in the community, except in exceptional circumstances.

[0088] The cell meets the cell selection criteria in 3GPP TS36.304 or TS38.304.

[0089] The reason for introducing the exception is that, in the existing mechanism, a cell may want to prevent a 1RX eRedCap UE or a 2Rx XR UE from initiating normal services; however, it may not want to prevent it from initiating emergency calls. Therefore, an instruction to allow the barred UE to initiate an emergency call is introduced in the system message: barringExemptEmergencyCall.

[0090] The exceptions mentioned above are used when a UE determines whether a cell is an acceptable cell, and the cell that has been barred or is considered to be barred is treated as an acceptable cell. A cell can be barred by SIB1 for terminals supporting certain features, such as: supporting only single-antenna RedCap reception (1rx RedCap); supporting dual-antenna RedCap reception (2rx RedCap); supporting only single-antenna eRedCap reception (1rx eRedCap); or supporting dual-antenna eRedCap reception (2rx eRedCap). Examples of these exceptions in NR are as follows:

[0091] Example 1: When IE cellBarred-RedCap1Rx is set to "barred" in SIB1, a RedCap UE that only supports the 1Rx branch can consider the cell as an acceptable cell if the following conditions are met: the cell selection criteria defined in Clause 5.2.3 of NR protocol TS38.304 are met, IE cellBarred in MIB is not set to "barred", IE barringExemptEmergencyCall is carried in SIB1, and if the RedCap UE only supports half-duplex FDD operation, halfDuplexRedCapAllowed must be set to "true".

[0092] Example 2: When IE cellBarred2RxXR is carried in SIB1, the 2RxXR UE can consider the cell as an acceptable cell if the following conditions are met: the cell selection criteria defined in Clause 5.2.3 of NR protocol TS38.304 are met, IE cellBarred in MIB is not set to "barred", and IE barringExemptEmergencyCall is carried in SIB1.

[0093] The above are merely examples and do not exhaustively list all the specific types of UEs supported by the current NR cell and the situations in which the corresponding UEs are allowed to initiate emergency calls, but the mechanisms used are similar. This omission should not be construed as limiting the scope of application of the embodiments in this application.

[0094] 5. RAN sharing

[0095] Cellular systems allow different operators to share cells, and shared cells broadcast multiple PLMN identifiers. If a UE discovers its associated PLMN from the PLMN identifiers broadcast in the system information broadcast, and if the UE is not barred, it may be allowed to access that cell to obtain services.

[0096] If the first cell broadcasts the identifier of the second PLMN but not the corresponding TAC (Transmission Control Account), the UE considers the first cell to be either not operable independently or disabled for the second PLMN. The UE cannot select the second PLMN to establish a Radio Resource Control (RRC) connection (during RRC connection establishment, the UE needs to report the identifier of the selected PLMN to the network). One possible reason (as an example, not constituting a deployment restriction) is that the base station governing the first cell is not connected to the core network node (e.g., AMF) corresponding to the second PLMN. The base station governing the first cell can only act as a secondary base station, working in conjunction with another base station (the primary base station) connected to the second PLMN's core network to provide dual connectivity services to the UE.

[0097] The following description, in conjunction with the accompanying drawings, details the communication operation execution method, apparatus, and related equipment provided in this application through some embodiments and application scenarios.

[0098] Referring to Figure 2, which is a flowchart of a communication operation execution method provided in an embodiment of this application, the communication operation execution method includes the following steps:

[0099] Step 101: If the first terminal determines that the first indication information indicates that the terminal matching the target characteristics regards the first cell as a prohibited cell, and determines that the first cell allows the terminal that regards the first cell as a prohibited cell to carry out emergency call services, the first terminal performs a first operation based on indication information other than the first indication information, and the first terminal is the terminal matching the target characteristics;

[0100] The first operation includes at least one of the following:

[0101] Determine whether the first cell is an acceptable cell, or whether the first cell is considered an acceptable cell;

[0102] Determine whether emergency call services are permitted in the first cell.

[0103] Specifically, the first terminal can determine, through the second indication information, that the first cell allows terminals that consider the first cell as a prohibited cell to conduct emergency call services. The first terminal can receive system messages (or be described as system information) to determine the first and second indication information. The first or second indication information can be implicitly carried in the system message or explicitly carried in the system message.

[0104] In one embodiment, the second indication information is used to instruct the first cell to allow terminals that consider the first cell as a prohibited cell to conduct emergency call services. It can also be expressed as the second indication information being used to instruct the first terminal to conduct emergency call services; or, the second indication information being used to instruct the first cell to allow emergency call services; the first terminal is a terminal that considers the first cell as a prohibited cell without considering the second indication information.

[0105] In one implementation, the second indication information is a barringExemptEmergencyCall. The second indication information can be used to indicate whether the cell allows emergency bearer services for a specific UE, which refers to a UE that would consider the cell barred if the cell did not broadcast the second indication information, as specified in TS 38.304.

[0106] In addition, emergency call services can also be described as emergency bearer services.

[0107] The terminal that matches the target characteristics can also be described as a terminal with specific capabilities or that supports specific communication characteristics.

[0108] Optionally, the terminal matching the target characteristic includes one of the following:

[0109] Terminals supporting RedCap capability; terminals supporting single receiver antenna (1Rx) redcap capability; terminals supporting dual receiver antenna (2Rx) redcap capability; terminals supporting enhanced redcap capability; terminals supporting 1Rx enhanced redcap capability; terminals supporting 2Rx enhanced redcap capability; terminals supporting 2Rx Extended Reality (XR) terminals (2Rx XR UE); terminals supporting Network Energy Save (NES) capability (NES UE); terminals supporting High Speed ​​Dedicated Network (HSDN) capability (HSDN-capable UE); terminals supporting Non-Terrestrial Network (NTN) capability (NTN UE).

[0110] Among them, a terminal that supports 1Rx reduction capability can refer to a terminal that only supports 1Rx reduction capability.

[0111] Among them, terminals that support 1Rx enhanced reduction capability can refer to terminals that only support 1Rx enhanced reduction capability.

[0112] For example, the first indication information may include cellBarred-RedCap1Rx, cellBarred2RxXR, or cellBarred-RedCap1Rx, etc.

[0113] The indication information other than the first indication information can refer to the indication information carried in the system message other than the first indication information. This indication information other than the first indication information can be implicitly carried in the system message or explicitly carried in the system message.

[0114] In addition, the indication information other than the first indication information may refer to indication information other than the first indication information used to indicate whether the first cell is prohibited (or expressed as whether the first cell is a prohibited cell).

[0115] Furthermore, the statement that the first operation is performed based on indication information other than the first indication information can be understood as performing the first operation without considering the first indication information; or, performing the first operation based on a first assumption, the first assumption including at least one of the following: assuming that the first indication information does not indicate that the terminal matching the target characteristics regards the first cell as a prohibited cell; assuming that the value of the first indication information is a second value or not a first value; when the value of the first indication information is a first value, the first indication information is used to indicate that the terminal matching the target characteristics regards the first cell as a prohibited cell, and the second value is different from the first value; assuming that the value of the first indication information represents non-prohibition; ignoring the first indication information.

[0116] In one embodiment, when the first terminal determines that the first indication information indicates that a terminal matching the target characteristics considers the first cell as a prohibited cell, and determines that the first cell allows terminals that consider the first cell as prohibited cells to conduct emergency call services, the first terminal performing a first operation based on indication information other than the first indication information may include:

[0117] If the first terminal determines that the first indication information indicates that the terminal matching the target characteristics regards the first cell as a prohibited cell, and determines that the first cell allows the terminal that regards the first cell as a prohibited cell to carry out emergency call services, the first terminal performs a first operation based on whether the first condition or the second condition is met, and the first terminal is the terminal matching the target characteristics;

[0118] The first operation includes at least one of the following:

[0119] Determine whether the first cell is an acceptable cell, or whether the first cell is considered an acceptable cell;

[0120] Determine whether emergency call services are permitted in the first cell;

[0121] The first condition includes at least one of the following:

[0122] The first cell did not broadcast the Tracking Area Code (TAC) corresponding to the Public Land Mobile Network (PLMN) associated with the first terminal;

[0123] The channel bandwidth broadcast by the first cell does not match the channel bandwidth supported by the first terminal;

[0124] When the first condition contains multiple terms, if every term of the first condition is satisfied, then the first condition is deemed satisfied; if at least one term of the first condition is not satisfied, then the first condition is deemed not satisfied.

[0125] The second condition includes any one of the following conditions:

[0126] If the first indication information does not instruct the terminal matching the target characteristics to regard the first cell as a prohibited cell, then the first cell does not meet the judgment condition of a prohibited cell;

[0127] If the first indication information does not instruct the terminal matching the target characteristics to designate the first cell as a prohibited cell, then the first cell meets the judgment criteria for a suitable cell or an acceptable cell.

[0128] If the value of the first indication information is the second value or is not the first value, then the first cell does not meet the judgment condition of a prohibited cell; wherein, when the value of the first indication information is the first value, the first indication information is used to instruct the terminal matching the target characteristics to regard the first cell as a prohibited cell, and the second value is different from the first value;

[0129] If the value of the first indication information is the second value or is not the first value, then the first cell meets the judgment condition of a suitable cell or an acceptable cell; wherein, when the value of the first indication information is the first value, the first indication information is used to instruct the terminal supporting the target capability to regard the first cell as a prohibited cell, and the second value is different from the first value;

[0130] Ignoring the first indication information, the first cell does not meet the criteria for prohibiting cells;

[0131] Ignoring the first indication information, the first cell meets the criteria for a suitable cell or an acceptable cell;

[0132] Based on indication information other than the first indication information, the first cell does not meet the criteria for a prohibited cell; or the terminal considers the first cell as a prohibited cell solely because of the first indication information.

[0133] Based on the indication information other than the first indication information, the first cell meets the criteria for a suitable cell or an acceptable cell.

[0134] In one implementation, the statement that the first cell does not meet the criteria for a prohibited cell if the first indication information does not indicate that the terminal matching the target characteristics considers the first cell as a prohibited cell can mean that the first terminal assumes that the first indication information does not indicate that the terminal matching the target characteristics considers the first cell as a prohibited cell, and according to the criteria for a prohibited cell: if the first terminal does not determine the first cell as a prohibited cell, then the first terminal considers the condition to be met; if the first terminal determines the first cell as a prohibited cell, then the first terminal considers the condition not to be met.

[0135] In one implementation, the statement that the first cell satisfies the judgment condition of a suitable cell or an acceptable cell if the first indication information does not indicate that the terminal matching the target characteristics will regard the first cell as a prohibited cell can mean that, assuming that the first indication information does not indicate that the terminal matching the target characteristics will regard the first cell as a prohibited cell, the first terminal, according to the judgment condition of a suitable cell or an acceptable cell, considers the condition satisfied if the first terminal determines the first cell as either a suitable cell or an acceptable cell; otherwise (i.e., if the first terminal does not determine the first cell as either a suitable cell or an acceptable cell), the first terminal considers the condition unsatisfactory.

[0136] In one implementation, the statement that if the value of the first indication information is a second value or not a first value, then the first cell does not meet the judgment condition for a prohibited cell can mean that, if the first terminal assumes that the value of the first indication information is a second value or not a first value, then according to the judgment condition for a prohibited cell: if the first terminal does not determine the first cell as a prohibited cell, then the first terminal considers the condition to be met; otherwise (i.e., if the first terminal determines the first cell as a prohibited cell), then the first terminal considers the condition not to be met.

[0137] In one implementation, the statement that the first cell satisfies the judgment condition of a suitable cell or an acceptable cell if the value of the first indication information is a second value or not a first value can mean that, assuming the value of the first indication information is a second value or not a first value, the first terminal determines the first cell as either a suitable cell or an acceptable cell based on the judgment condition of a suitable cell or an acceptable cell. Otherwise (if the first terminal does not determine the first cell as either a suitable cell or an acceptable cell), the first terminal considers the condition not to be met.

[0138] In one implementation, the statement that the first cell does not meet the criteria for a prohibited cell when ignoring the first indication information can mean that, assuming the first indication information is not configured or carried in the broadcast message, the first terminal considers the condition to be met if it does not identify the first cell as a prohibited cell; otherwise (if the first terminal identifies the first cell as a prohibited cell), the first terminal considers the condition not met.

[0139] In one implementation, the statement that the first cell satisfies the judgment condition of a suitable cell or an acceptable cell when ignoring the first indication information can mean that, assuming the first indication information is not configured or carried in the broadcast message, the first terminal determines the first cell as either a suitable cell or an acceptable cell based on the judgment condition of a suitable cell or an acceptable cell; otherwise (if the first terminal does not determine the first cell as either a suitable cell or an acceptable cell), the first terminal considers the condition not to be met.

[0140] In one implementation, the statement that the first cell does not meet the criteria for a prohibited cell based on indication information other than the first indication information can mean that, based on other system messages besides the first indication information, if the first cell does not meet the criteria for a prohibited cell; or if the terminal considers the first cell a prohibited cell solely because of the first indication information, then the terminal considers the condition to be met; otherwise (i.e., based on other system messages besides the first indication information, if the first cell meets the criteria for a prohibited cell; or based on other system messages besides the first indication information, if the terminal considers the first cell a prohibited cell), then the terminal considers the condition not met.

[0141] In one embodiment, the determination that the first cell meets the criteria for a suitable cell or an acceptable cell based on indication information other than the first indication information can mean that, based on other system message indications besides the first indication information, if the first cell meets the criteria for a suitable cell or an acceptable cell, the terminal considers the condition to be met; otherwise (i.e., based on other system message indications besides the first indication information, the first cell does not meet either the criteria for a suitable cell or the criteria for an acceptable cell), the terminal considers the condition not met.

[0142] The condition that the first cell does not meet the criteria for a prohibited cell can also be expressed as that, according to the system information, the cell is not prohibited or considered as prohibited. The system information may include MIB or SIB1.

[0143] In one implementation, when the first terminal meets the first condition, the first operation includes: determining that the first cell is not an acceptable cell, or not considering the first cell as an acceptable cell; and determining that emergency call services are not permitted in the first cell.

[0144] In one implementation, when the first terminal meets the second condition, the first operation includes: determining that the first cell is an acceptable cell, or regarding the first cell as an acceptable cell; and determining that emergency call services are permitted in the first cell.

[0145] In addition, the method for determining whether the channel bandwidth broadcast by the first cell matches the channel bandwidth supported by the first terminal can be determined based on the description in 3GPP TS38.331.

[0146] In addition, the criteria for determining the prohibited cell can be determined based on the relevant descriptions in 3GPP TS38.331 and TS38.304.

[0147] In one implementation, if, based on the first operation, the first terminal determines that the first cell is an acceptable cell, or the first terminal regards the first cell as an acceptable cell; or the first terminal determines that it is allowed to conduct emergency call services in the first cell, then the first terminal camps on the first cell and initiates emergency call services when needed.

[0148] In one implementation, when the first terminal determines that the first cell allows terminals that consider the first cell as a prohibited cell to make emergency calls, if the reason the first terminal determines that the first cell is not an acceptable cell includes only the first indication information; or the reason the first terminal determines that the first cell is not a suitable cell includes only the first indication information; or the reason the first terminal determines that the first cell is a prohibited cell includes only the first indication information, then the first terminal considers the first cell as an acceptable cell.

[0149] In one embodiment, a first terminal receives a first broadcast message (or a first system message) and a second broadcast message (or a second system message) from a first cell. The first broadcast message and the second broadcast message may be the same broadcast message or two different broadcast messages. The first system message and the second system message may be the same system message or two different system messages.

[0150] The first broadcast message carries first indication information, and according to the first indication information, the first terminal regards the first cell as a barred cell.

[0151] The second broadcast message carries second indication information. Based on this second indication information, when determining whether the first cell is an acceptable cell, the first terminal assumes that the first indication information did not instruct the first terminal to consider the first cell as a barred cell. That is, when the first terminal performs the acceptable cell determination, it rewrites / overrides the first indication information according to the second indication information. Thus, when determining whether the first cell is a suitable cell, the first terminal makes the determination based on the first indication information broadcast by the first cell; when determining whether the first cell is an acceptable cell, the first terminal obtains an alternative value for the first indication information based on the second indication information, and determines whether the first cell meets the conditions for an acceptable cell based on the alternative value.

[0152] In one embodiment, the first indication information includes the following form:

[0153] When the first indication information takes a first value, the first terminal regards the first cell as a prohibited cell; when the first indication information takes a second value, the first terminal considers that the first indication information does not instruct the first terminal to regard the first cell as a prohibited cell.

[0154] The second instruction information includes the following forms:

[0155] When the second indication information takes the first value, the first terminal determines whether the first cell meets the conditions of an Acceptable cell based on the value of the first indication information; when the second indication information takes the second value, the first terminal assumes that the first indication information did not instruct the first terminal to regard the first cell as a prohibited cell, and determines whether the first cell meets the conditions of an Acceptable cell based on this assumption.

[0156] In one embodiment, a first terminal receives a first message from a first cell. The first message may carry first indication information, which may have two different values, corresponding to a first value and a second value; or, the first message may carry second indication information, which may have two different values, corresponding to a first value and a second value.

[0157] In one embodiment, the first message may optionally carry first indication information. When the first indication information is carried, it can be understood that the first indication information takes a first value; when the first indication information is not carried, it can be understood that the first indication information takes a second value. Alternatively, the first message may optionally carry second indication information. When the second indication information is carried, it can be understood that the second indication information takes a first value; when the second indication information is not carried, it can be understood that the second indication information takes a second value.

[0158] The first message may optionally carry first indication information. When the first indication information is carried, it can be understood that the first indication information takes a second value; when the first indication information is not carried, it can be understood that the first indication information takes a first value. Alternatively, the first message may optionally carry second indication information. When the second indication information is carried, it can be understood that the second indication information takes a second value; when the second indication information is not carried, it can be understood that the second indication information takes a first value. This embodiment does not limit this.

[0159] In related technologies, a terminal (UE) can determine whether a cell can be used as an acceptable cell based on one of the following mechanisms:

[0160] Option 1: The UE determines whether the first cell meets the Acceptable cell condition based on the first indication information broadcast by the first cell and A additional indications; or

[0161] Option 2: If the first indication information broadcast in the first cell indicates that the UE is barred, the UE determines whether the first cell can be used as the UE's Acceptable cell based on B additional indications and the second indication information broadcast by the cell (allowing the UE to initiate an emergency call).

[0162] Where: A>B. The A indications include: the B indications, and C other indications different from the B indications. A=B+C; for different types and capabilities of UE, the values ​​of A, B, and C may be different, and all are integers greater than 0.

[0163] The first indication information is related to the UE's capabilities or supported communication characteristics. For example, the first indication information indicates whether a UE with specific capabilities or supporting specific communication characteristics is allowed or not allowed to camp on the first cell, such as allowing or prohibiting 1Rx RedCap camping.

[0164] In Scheme 2, when determining whether the first cell can be an acceptable cell (or, in other words, determining whether the first cell meets the conditions for an acceptable cell), C indications are not considered. If all or some of these C indications are not considered, an emergency call setup anomaly will occur in the UE. An example is as follows: In related technologies, under RAN sharing, if the first cell sends:

[0165] The first identifier (i.e., the first indication information) bars a certain type of UE (e.g., cellBarred-RedCap1Rx is set to barred, so that barred only supports RedCap UEs with 1Rx); and

[0166] The second identifier (i.e., the second indication information) indicates that the cell allows the initiation of an emergency call (such as carrying a barringExemptEmergencyCall).

[0167] When determining whether the first cell is an Acceptable cell, the UE no longer determines whether the first cell broadcasts the TAC corresponding to the PLMN associated with the UE. Whether the first cell broadcasts the PLMN associated with the UE and the TAC corresponding to the PLMN is one of the A indications, but not one of the B indications. In a RAN sharing scenario, the first cell may broadcast multiple PLMN identifiers, such as a first PLMN identifier and a second PLMN identifier. The first cell also broadcasts the TAC corresponding to the first PLMN identifier, but not the TAC corresponding to the second PLMN identifier. Assume that the PLMN associated with the UE includes the second PLMN but does not include the first PLMN.

[0168] A potential risk associated with this technology is that the UE might identify the first cell as an acceptable cell and initiate an emergency call. During call setup, the UE needs to establish an RRC connection, and in the RRC connection establishment completion message, it needs to report the selected PLMN. If the UE reports the selected PLMN (i.e., the second PLMN), it may cause call failure. For example, the base station of the first cell may not be able to send the Non-Access Stratum (NAS) message carried in the RRC connection establishment completion message to the core network corresponding to the second PLMN, causing the NAS message to fail to be transmitted to the core network (because the base station of the first cell is not connected to the core network corresponding to the second PLMN; therefore, the first cell does not broadcast the TAC corresponding to the second PLMN).

[0169] In the above example, for a UE that has selected the second PLMN, the first cell cannot be used as an Acceptable cell; for a UE that has selected the first PLMN, the first cell can be used as an Acceptable cell.

[0170] Another example is as follows: The C indications include the channel bandwidth broadcast by the first cell. When the channel bandwidth supported by the UE does not match the channel bandwidth broadcast by the first cell, the UE should consider the first cell not to meet the acceptable cell condition. When determining an acceptable cell based on Scheme 2, the first cell whose broadcast channel bandwidth does not match the channel bandwidth supported by the UE might be determined as the UE's acceptable cell.

[0171] This application embodiment can solve the problem of emergency call initiation failure caused by the incomplete acceptable cell determination mechanism (C indications are not considered) in Solution 2 of the related technology. This application embodiment allows the UE to determine whether the first cell is an acceptable cell, or whether to regard the first cell as an acceptable cell, by using indication information other than the first indication information when determining whether the first cell can be used as an acceptable cell; or to determine whether emergency call services are allowed in the first cell. This enables the terminal to consider all the additional A indications and avoids the UE from selecting a cell that cannot initiate an emergency call as an acceptable cell, such as: the channel bandwidth supported by the UE and the channel bandwidth broadcast by the cell do not match; or the cell does not broadcast the TAC corresponding to the PLMN associated with the UE.

[0172] In this embodiment, when the first terminal determines that the first indication information indicates that a terminal matching the target characteristics considers the first cell as a prohibited cell, and determines that the first cell allows terminals that consider the first cell as prohibited cells to conduct emergency call services, the first terminal performs a first operation based on indication information other than the first indication information, wherein the first terminal is a terminal matching the target characteristics; wherein the first operation includes at least one of the following: determining whether the first cell is an acceptable cell, or whether the first cell is considered an acceptable cell; determining whether emergency call services are permitted in the first cell. This avoids the situation where the first indication information indicates that a terminal matching the target characteristics considers the first cell as a prohibited cell, and the terminal only determines whether the first cell is an acceptable cell based on a specific indication, leading to the misjudgment of a cell that does not match the terminal as an acceptable cell, or the conduct of emergency call services in a cell that does not match the terminal, thus reducing the probability of misjudgment when the terminal determines an acceptable cell.

[0173] Optionally, the first terminal performs a first operation based on indication information other than the first indication information, including:

[0174] The first terminal determines whether the target condition is met based on indication information other than the first indication information.

[0175] The first terminal performs a first operation based on whether the target condition is met;

[0176] The target condition includes any one of the following:

[0177] The first judgment condition used to determine that the first cell is a prohibited cell;

[0178] The second judgment condition is used to determine whether the first cell is a suitable cell or an acceptable cell.

[0179] Wherein, the first judgment condition or the second judgment condition may be based on a first assumption, and the first assumption includes at least one of the following:

[0180] Assuming the first indication information does not instruct a terminal matching the target characteristics to consider the first cell as a prohibited cell;

[0181] Assume the value of the first indication information is a second value or not a first value; when the value of the first indication information is a first value, the first indication information is used to instruct the terminal matching the target characteristics to regard the first cell as a prohibited cell, and the second value is different from the first value;

[0182] Assume the value of the first indication information represents that it is not prohibited;

[0183] Ignore the first instruction information.

[0184] In one implementation, the first judgment condition may refer to the judgment condition for prohibiting cells.

[0185] In one implementation, the second judgment condition may refer to the judgment condition of a suitable cell or an acceptable cell.

[0186] In one implementation, the first judgment condition or the second judgment condition may be based on a first assumption. It can be understood that judging whether the first judgment condition or the second judgment condition is satisfied may be based on the first assumption.

[0187] In one implementation, the target condition may include either the first condition or the second condition described above.

[0188] In this embodiment, the first terminal determines whether the target condition is met based on indication information other than the first indication information, and performs a first operation based on whether the target condition is met. In this way, by determining whether the indication information other than the first indication information meets the first judgment condition or the second judgment condition to perform the first operation, it is possible to avoid the terminal that indicates the target characteristics of the first indication information to regard the first cell as a prohibited cell, and the terminal only determines whether the first cell is an acceptable cell based on a specific indication, which may lead to the terminal judging a cell that does not match the terminal as an acceptable cell, or performing emergency call services in a cell that does not match the terminal. This can reduce the probability of the terminal misjudging an acceptable cell.

[0189] Optionally, the target condition is based on a first assumption, which includes at least one of the following:

[0190] Assuming the first indication information does not instruct a terminal matching the target characteristics to consider the first cell as a prohibited cell;

[0191] Assume the value of the first indication information is a second value or not a first value; when the value of the first indication information is a first value, the first indication information is used to instruct the terminal matching the target characteristics to regard the first cell as a prohibited cell, and the second value is different from the first value;

[0192] Assume that the value of the first indication information represents "not Barred";

[0193] Ignore the first instruction information.

[0194] Here, assuming that the value of the first indication information represents notBarred, it can mean that the value of the first indication information is notBarred.

[0195] In one implementation, the target condition is based on a first assumption, which can be understood as determining whether the target condition is satisfied based on the first assumption.

[0196] In one implementation, taking the target condition including a first judgment condition as an example, the target condition may include any one of the following:

[0197] The first judgment condition used to determine that the first cell is a prohibited cell is assumed to be notified when the first indication information does not indicate that the terminal matching the target characteristics regards the first cell as a prohibited cell;

[0198] Assuming the value of the first indication information is a second value or not a first value, it is used as a first judgment condition to determine that the first cell is a prohibited cell; when the value of the first indication information is a first value, the first indication information is used to instruct the terminal matching the target characteristics to regard the first cell as a prohibited cell, and the second value is different from the first value;

[0199] The first judgment condition used to determine that the first cell is a prohibited cell when the first indication information is ignored.

[0200] In one implementation, taking the target condition including a second judgment condition as an example, the target condition may include any one of the following:

[0201] The second judgment condition used to determine whether the first cell is a suitable or acceptable cell when the first indication information does not indicate that the terminal matching the target characteristics regards the first cell as a prohibited cell;

[0202] Assuming the value of the first indication information is a second value or not a first value, it is used as a second judgment condition to determine whether the first cell is a suitable cell or an acceptable cell; when the value of the first indication information is a first value, the first indication information is used to instruct the terminal matching the target characteristics to regard the first cell as a prohibited cell, and the second value is different from the first value;

[0203] The second judgment condition used to determine whether the first cell is a suitable cell or an acceptable cell when the first indication information is ignored.

[0204] In this embodiment, the target condition is based on a first assumption, thereby enabling the first operation to be performed based on the target condition based on the first assumption. This avoids the situation where the terminal that matches the target characteristics of the first indication information treats the first cell as a prohibited cell, and the terminal only determines whether the first cell is an acceptable cell based on a specific indication, which may lead to the terminal misjudging a cell that does not match the terminal as an acceptable cell, or conducting emergency call services in a cell that does not match the terminal. This reduces the probability of the terminal misjudging an acceptable cell.

[0205] Optionally, the first determination condition includes at least one of the following:

[0206] The first cell did not broadcast the Tracking Area Code (TAC) corresponding to the Public Land Mobile Network (PLMN) associated with the first terminal;

[0207] The channel bandwidth broadcast by the first cell does not match the channel bandwidth supported by the first terminal.

[0208] or,

[0209] The second judgment condition includes at least one of the following:

[0210] The first cell broadcasts the TAC corresponding to the PLMN associated with the first terminal;

[0211] The channel bandwidth broadcast by the first cell matches the channel bandwidth supported by the first terminal.

[0212] The TAC corresponding to the PLMN can include one or more TACs. Taking multiple TACs as an example, TACs can be represented in the form of a TAC list. The TAC corresponding to the PLMN associated with the first terminal can include: the list of TACs associated with the PLMN associated with the first terminal.

[0213] In one implementation, if the first terminal is associated with N PLMNs, then the first cell does not broadcast the TAC corresponding to the PLMN associated with the first terminal, which may include:

[0214] The system information broadcast in the first cell does not include the TAC corresponding to any of the N PLMNs.

[0215] It should be noted that the first cell did not broadcast the TAC corresponding to the PLMN associated with the first terminal. This can be understood as the first cell not broadcasting the TAC corresponding to any one of the associated PLMN(s) of the first terminal.

[0216] In this embodiment, if the first cell does not broadcast the TAC corresponding to the PLMN associated with the first terminal, the first terminal can determine that the first cell is not an acceptable cell, or not regard the first cell as an acceptable cell; or the first terminal determines that it is not allowed to conduct emergency call services in the first cell. This can avoid the situation in related technologies where if the terminal regards the first cell as a prohibited cell based on the first indication information broadcast by the first cell, the terminal will not consider whether the first cell broadcasts the TAC or TAC list corresponding to the PLMN associated with the first terminal when determining whether the first cell is an acceptable cell, which may lead to the terminal misjudging a cell that does not match the terminal as an acceptable cell. This can reduce the probability of the terminal misjudging an acceptable cell.

[0217] In this embodiment, if the channel bandwidth broadcast by the first cell does not match the channel bandwidth supported by the first terminal, the first terminal can determine that the first cell is not an acceptable cell, or not regard the first cell as an acceptable cell; or the first terminal can determine that emergency call services are not allowed in the first cell. This avoids the situation in related technologies where, if the terminal regards the first cell as a prohibited cell based on the first indication information broadcast by the first cell, the terminal will not consider whether the channel bandwidth broadcast by the first cell matches the channel bandwidth supported by the first terminal when determining whether the first cell is an acceptable cell, thus making a misjudgment of a cell that does not match the terminal as an acceptable cell. This can reduce the probability of the terminal misjudging an acceptable cell.

[0218] Optionally, if the first judgment condition is met or if the second judgment condition is not met, the first operation includes at least one of the following:

[0219] Determine that the first cell is not an acceptable cell, or do not regard the first cell as an acceptable cell;

[0220] It has been determined that emergency call services are not permitted in the first cell.

[0221] Among them, not meeting the second judgment condition can mean that the first community does not meet the judgment condition of a suitable community, nor does it meet the judgment condition of an acceptable community.

[0222] Optionally, if the first judgment condition is not met or if the second judgment condition is met, the first operation includes at least one of the following:

[0223] The first cell is determined to be an acceptable cell, or the first cell is regarded as an acceptable cell;

[0224] It was determined that emergency call services were permitted in the first cell.

[0225] The second judgment condition can refer to the first cell meeting at least one of the judgment conditions for a suitable cell or the judgment conditions for an acceptable cell.

[0226] Optionally, the first determination condition further includes at least one of the following:

[0227] The first terminal receives a Master Information Block (MIB) sent by the first cell, and the MIB indicates that the first cell is blocked;

[0228] The first terminal receives a third indication message, which is used to indicate that a half-duplex terminal is not allowed to camp on the first cell. The first terminal is a Reduce Capability (RedCap) terminal or an enhanced RedCap (eRedCap) terminal, and the first terminal only supports half-duplex frequency division multiplexing (FDD).

[0229] or

[0230] The second judgment condition also includes at least one of the following:

[0231] The first terminal receives the MIB sent by the first cell, and the MIB indicates that the first cell is not a prohibited cell;

[0232] The first terminal receives a third indication message, which is used to indicate that a half-duplex terminal is allowed to camp on the first cell. The first terminal is a RedCap terminal or an eRedCap terminal, and the first terminal only supports half-duplex FDD.

[0233] In this embodiment, the first terminal can also consider the MIB message or the third indication information to determine whether the first cell is an acceptable cell, or whether the first cell is regarded as an acceptable cell; or whether it is allowed to conduct emergency call services in the first cell; which can further reduce the probability of the terminal misjudging the acceptable cell.

[0234] Optionally, if the first terminal determines that all indications other than the first indication information indicate that the first cell is not considered a prohibited cell, the first operation includes:

[0235] The first cell is determined to be an acceptable cell, or the first cell is regarded as an acceptable cell;

[0236] It was determined that emergency call services were permitted in the first cell.

[0237] Wherein, the first terminal determines that all indication information other than the first indication information indicates that the first cell is not regarded as a prohibited cell. This can be understood as the first terminal regarding the first cell as a prohibited cell solely because of the first indication information.

[0238] In this embodiment, if the first terminal considers the first cell as a prohibited cell solely because of the first indication information, the first terminal determines the first cell as an acceptable cell, or considers the first cell as an acceptable cell; or, determines that emergency call services are permitted in the first cell. This reduces the probability of misjudging an acceptable cell when the first indication information indicates that a terminal matching the target characteristics has considered the first cell as a prohibited cell, in cases where the first cell is determined to allow emergency call services from terminals that consider the first cell as a prohibited cell.

[0239] Optionally, the method further includes:

[0240] The first terminal receives at least one of a first message and a second message from the first cell;

[0241] The first terminal determines the first indication information and the second indication information based on at least one of the first message and the second message. The first indication information is used to instruct the terminal matching the target characteristics to regard the first cell as a prohibited cell, and the second indication information is used to instruct the first cell to allow the terminal that regards the first cell as a prohibited cell to carry out emergency call services.

[0242] The first message can be a broadcast message (such as a system message). The second message can be a broadcast message (such as a system message). The first indication information and the second indication information can be determined by the same message (such as the first message or the second message); or the first indication information and the second indication information can be determined by two different messages. For example, the first terminal determines the first indication information based on the first message, and the first terminal determines the second indication information based on the second message.

[0243] In one embodiment, the first terminal can receive a first message and a second message from a first cell; the first message and the second message can be the same message or different messages; the first terminal can determine first indication information based on the first message and determine second indication information based on the second message, wherein the first indication information is used to instruct terminals matching the target characteristics to regard the first cell as a prohibited cell, and the second indication information is used to instruct the first cell to allow terminals that regard the first cell as a prohibited cell to conduct emergency call services.

[0244] In this embodiment, the first terminal receives at least one of a first message and a second message from the first cell; the first terminal determines the first indication information and the second indication information based on the first message and the second message, so that the first terminal can obtain the first indication information and the second indication information from the same message or different messages.

[0245] Optionally, when the value of the first indication information is a first value, the first indication information is used to instruct the terminal matching the target characteristics to regard the first cell as a prohibited cell;

[0246] or

[0247] When the value of the second indication information is a third value, the second indication information is used to indicate that the first cell allows terminals that regard the first cell as a prohibited cell to make emergency calls.

[0248] In addition, if the value of the first indication information is a second value, the first indication information can be used to indicate that the terminal matching the target characteristics does not regard the first cell as a prohibited cell.

[0249] Alternatively, if the value of the second indication information is the fourth value, the second indication information can be used to indicate that the first cell does not allow terminals that regard the first cell as a prohibited cell to make emergency calls.

[0250] The first value can be Barred, and the second value can be not barred (or notBarred); or, during air interface transmission, when the first or second value is encoded as a binary indicator, the first value can be 1 and the second value can be 0; or, the first value can be 0 and the second value can be 1. This embodiment does not limit the specific values ​​of the first and second values.

[0251] The third value can be 1 and the fourth value can be 0; or the third value can be 0 and the fourth value can be 1. This embodiment does not limit the specific values ​​of the third and fourth values.

[0252] The following examples further illustrate the methods for performing communication operations:

[0253] Example group 1:

[0254] In this example group, the first message is a system message, and the value of the first instruction information is reset by carrying optional second instruction information through system information.

[0255] The method for determining a residential area includes the following steps:

[0256] Step (11): The UE receives the second indication information (optional) and the first indication information (optional) from the first cell;

[0257] Step (12): The UE determines a first value based on at least one of the first indication information and the second indication information; and determines whether the first cell is an Acceptable cell based on the mechanism specified in the protocol. The first value is used to determine whether the first cell is an Acceptable cell.

[0258] The first value can also be expressed as the value of the first indication information used to determine whether the first cell meets the Acceptable cell condition or the assumed value of the first indication information.

[0259] The first value can be the value of the first indication information, or it can be determined by whether the first indication information is carried.

[0260] Example 1a:

[0261] The above step (11) includes: the UE receiving a first system message and a second system message sent by the first cell, the first system message carrying cellBarred-RedCap1Rx (i.e., the first indication information) and set to barred, and the second system message carrying barringExemptEmergencyCall (i.e., the second indication information);

[0262] The above step (12) includes: based on the occurrence or second system message carrying optional information element (IE): barringExemptEmergencyCall (i.e. the second indication information is carried to indicate to the UE: assuming the first indication information does not instruct the UE to regard the first cell as a prohibited cell), the UE assumes that the value of cellBarred-RedCap1Rx is notBarred (or considers the value of cellBarred-RedCap1Rx to be notBarred); and based on the assumed value of cellBarred-RedCap1Rx and the mechanism specified in the protocol, determines whether the first cell is an Acceptable cell, that is, determines whether the first cell meets the Acceptable cell condition.

[0263] Optionally, in step (12), before the UE determines the assumed value of cellBarred-RedCap1Rx based on the occurrence or being carried by the optional IE: barringExemptEmergencyCall, the UE determines that at least one of the following conditions is satisfied:

[0264] The first system message carries cellBarred-RedCap1Rx;

[0265] The first system message carries cellBarred-RedCap1Rx, and cellBarred-RedCap1Rx is set to barred;

[0266] The MIB instruction sent by the first cell indicates that the first cell is not barred, for example, Cellbarred IE takes the value notBarred.

[0267] Example 1b:

[0268] The above step (11) includes: the UE receiving a first system message and a second system message sent by the first cell, wherein the first system message carries cellBarred2RxXR (i.e., first indication information) and the second system message carries barringExemptEmergencyCall (i.e., second indication information).

[0269] It should be noted that, according to the existing protocol, if SIB1 carries cellBarred2RxXR, then the UE considers the first cell to be barred.

[0270] The above step (12) includes: based on the occurrence or the second system message carrying the optional IE: barringExemptEmergencyCall (i.e. the second indication information is carried to indicate to the UE: assuming the first indication information does not instruct the UE to regard the first cell as a prohibited cell), the UE assumes that cellBarred2RxXR is not carried by the first system message (or considers that the first system message does not carry cellBarred2RxXR); and based on the above assumption (cellBarred2RxXR is not carried by the first system message) and the mechanism specified in the protocol, determines whether the first cell is an Acceptable cell, that is, determines whether the first cell meets the Acceptable cell condition.

[0271] Optionally, in step (12), the UE determines the following condition is met before the optional IE: barringExemptEmergencyCall appears or is carried, assuming cellBarred2RxXR is not carried by the first system message:

[0272] The MIB instruction sent by the first cell indicates that the first cell is not barred, for example, Cellbarred IE takes the value notBarred.

[0273] Example 1c:

[0274] The above step (11) includes: the UE receiving a first system message sent by the first cell, the first system message carrying cellBarred-RedCap1Rx (i.e., first indication information), set to barred (i.e., according to the first indication information, the UE regards the first cell as a prohibited cell), and the system message sent by the first cell does not carry barringExemptEmergencyCall (i.e., second indication information);

[0275] The above step (12) includes: the UE determines whether the first cell is an Acceptable cell based on the value of cellBarred-RedCap1Rx in SIB1 (barred or notBarred) according to the mechanism specified in the protocol.

[0276] In Examples 1a and 1c, the UE is a RedCap UE that only supports 1Rx; the first system message and the second system message can be the same message (e.g., SIBX) or two different messages (e.g., SIBX and SIBY mapped to different System Information (SI) message transmissions).

[0277] In Example 1b, the UE is a 2Rx XR UE; the first system message and the second system message can be the same message (e.g., SIBX) or two different messages (e.g., SIBX and SIBY mapped to different SI message transmissions).

[0278] The above example does not change the method for determining Acceptable cells as specified in the protocol. Compared with the mechanism of determining Acceptable cells based on barringExemptEmergencyCall in related technologies, some determination steps are skipped. For example, the skipped steps include: if the first cell does not carry the TAC corresponding to the PLMN associated with the UE, the first cell is determined not to be an Acceptable cell. The above example assumes that the first indication information does not instruct the UE to regard the first cell as a prohibited cell. The above determination steps will not be skipped because the first indication information instructs the UE to regard the first cell as a prohibited cell. This can prevent the UE from selecting a cell that cannot work independently as an Acceptable cell and camping there.

[0279] Example group two:

[0280] In this example group, the first message is a system message, which carries the second indication information to indicate whether the value of the first indication information should be reset.

[0281] The method for determining a residential area includes the following steps:

[0282] Step (21): The UE receives first indication information and second indication information from the first cell;

[0283] Step (22): The UE determines a first value based on at least one of the first indication information and the second indication information; and determines whether the first cell is an Acceptable cell based on the mechanism specified in the protocol. The first value is used to determine whether the first cell is an Acceptable cell.

[0284] The first value can also be expressed as the value of the first indication information used to determine whether the first cell meets the Acceptable cell condition or the assumed value of the first indication information.

[0285] Example 2a:

[0286] The above step (21) includes: the UE receiving a first system message and a second system message sent by the first cell, the first system message carrying cellBarred-RedCap1Rx (i.e., the first indication information) and set to barred, and the second system message carrying barringExemptEmergencyCall (i.e., the second indication information);

[0287] The above step (22) includes: the second system message carries the IE barringExemptEmergencyCall and is set to the first value; the UE assumes that the value of cellBarred-RedCap1Rx is notBarred (or assumes that the value of cellBarred-RedCap1Rx is notBarred); and based on the assumed value of cellBarred-RedCap1Rx and the mechanism specified in the protocol, determines whether the first cell is an Acceptable cell, that is, determines whether the first cell meets the Acceptable cell condition.

[0288] Example 2b:

[0289] The above step (21) includes: the UE receiving a first system message and a second system message sent by the first cell, the first system message carrying cellBarred-RedCap1Rx (i.e., the first indication information) and set to barred, and the second system message carrying barringExemptEmergencyCall (i.e., the second indication information);

[0290] The above step (22) includes: the second system message carries the IE barringExemptEmergencyCall and is set to the second value. The UE determines whether the first cell is an Acceptable cell based on the cellBarred-RedCap1Rx (representing either barred or notBarred) carried in the first system message and the mechanism specified in the protocol, that is, whether the first cell meets the Acceptable cell condition.

[0291] Optionally, in step (22), before the UE determines the assumed value of cellBarred-RedCap1Rx based on the value of IE:barringExemptEmergencyCall, the UE determines that at least one of the following conditions is met:

[0292] The first system message carries cellBarred-RedCap1Rx;

[0293] The first system message carries cellBarred-RedCap1Rx, and cellBarred-RedCap1Rx is set to barred;

[0294] The MIB instruction sent by the first cell indicates that the first cell is not barred, for example, Cellbarred IE takes the value notBarred.

[0295] In Examples 2a and 2b, the UE is a RedCap UE that only supports 1Rx; the first system message and the second system message can be the same message (e.g., SIBX) or two different messages (e.g., SIBX and SIBY mapped to different SI message transmissions).

[0296] The above example does not change the method for determining Acceptable cells as specified in the protocol. Compared with the mechanism of determining Acceptable cells based on barringExemptEmergencyCall in related technologies, some determination steps are skipped. For example, the skipped steps include: if the first cell does not carry the TAC corresponding to the PLMN associated with the UE, the first cell is determined not to be an Acceptable cell. The above example assumes that the first indication information does not instruct the UE to regard the first cell as a prohibited cell. The above determination steps will not be skipped because the first indication information instructs the UE to regard the first cell as a prohibited cell. This can prevent the UE from selecting a cell that cannot work independently as an Acceptable cell and camping there.

[0297] Example group three:

[0298] In this example group, the terminal camps on any cell state.

[0299] The method for determining a residential area includes the following steps:

[0300] Step (31): The UE receives the second indication information (optional) and the first indication information (optional) from the first cell;

[0301] Step (32): If the UE determines that the first cell does not meet the condition of an Acceptable cell only because of the value of the first indication information, and the value of the second indication information is the first value, the UE will regard the first cell as an Acceptable cell.

[0302] The first value can also be expressed as the value of the first indication information used to determine whether the first cell meets the Acceptable cell condition or the assumed value of the first indication information.

[0303] The first value can be the value of the first indication information, or it can be determined by whether the first indication information is carried.

[0304] The value of the second indication information is the first value. It can be the first value among two selectable values, or it can be whether the second indication information is carried or not.

[0305] Example 3a:

[0306] The above step (31) includes: the UE receiving a first system message and a second system message sent by the first cell, the first system message carrying cellBarred-RedCap1Rx (i.e., the first indication information) and set to barred, and the second system message carrying barringExemptEmergencyCall (i.e., the second indication information);

[0307] The above step (32) includes: the UE determines that the first cell does not meet the Acceptable cell condition only because cellBarred-RedCap1Rx is set to barred (or it can be stated that if cellBarred-RedCap1Rx is set to not barred, then the first cell meets the Acceptable cell condition), and the second system message carries the optional IE: barringExemptEmergencyCall, then the UE determines that the first cell is an Acceptable cell or regards the first cell as an Acceptable cell, that is, it determines that the first cell meets the Acceptable cell condition.

[0308] Optionally, in step (32), the prerequisite for the UE to determine that the first cell is an Acceptable cell or to regard the first cell as an Acceptable cell further includes at least one of the following conditions being met:

[0309] The first system message carries cellBarred-RedCap1Rx;

[0310] The first system message carries cellBarred-RedCap1Rx, and cellBarred-RedCap1Rx is set to barred;

[0311] The MIB instruction sent by the first cell indicates that the first cell is not barred, for example, Cellbarred IE value is notBarred;

[0312] If the RedCap UE only supports half-duplex FDD, halfDuplexRedCapAllowed needs to be set to "true" in the first system message.

[0313] Example 3b:

[0314] The above step (31) includes: the UE receiving a first system message and a second system message sent by the first cell, the first system message carrying cellBarred2RxXR, and the second system message carrying barringExemptEmergencyCall (i.e., the second indication information);

[0315] The above step (32) includes: the UE determines that the first cell does not meet the Acceptable cell condition only because the first system message carries cellBarred2RxXR (i.e., the first indication information) (or it can be stated that if the first system message does not carry cellBarred2RxXR, then the first cell meets the Acceptable cell condition, or it can be stated that the only reason the UE determines that the first cell does not meet the Acceptable cell condition is that the first system message of the first cell carries cellBarred2RxXR), and the second system message carries the optional IE: barringExemptEmergencyCall, then the UE determines that the first cell is an Acceptable cell or regards the first cell as an Acceptable cell, that is, determines that the first cell meets the Acceptable cell condition.

[0316] It should be noted that, according to the existing protocol, if SIB1 carries cellBarred2RxXR, then the UE considers the first cell to be barred.

[0317] Optionally, in step (32), the prerequisite for the UE to determine that the first cell is an Acceptable cell or to regard the first cell as an Acceptable cell further includes:

[0318] The MIB instruction sent by the first cell indicates that the first cell is not barred, for example, Cellbarred IE takes the value notBarred.

[0319] In Example 3a, the UE is a RedCap UE that only supports 1Rx; the first system message and the second system message can be the same message (e.g., SIBX) or two different messages (e.g., SIBX and SIBY mapped to different SI message transmissions).

[0320] In Example 3b, the UE is a 2Rx XR UE; the first system message and the second system message can be the same message (e.g., SIBX) or two different messages (e.g., SIBX and SIBY mapped to different SI message transmissions).

[0321] Example 4:

[0322] When the cell status of the first cell is indicated as "barred" or when the first terminal considers the cell status of the first cell to be "barred":

[0323] Except in the following circumstances, the first terminal is not allowed to select or reselect to the first cell:

[0324] When the second indication information is carried in the second SIB, the first terminal considers the first indication information as "not barred"; if the first cell meets the criteria for an acceptable cell, the first terminal considers the first cell as an acceptable cell.

[0325] One implementation: When the second indication information is carried in the second SIB, it includes: when the first indication information in the first SIB is set to "barred" and the second indication information is carried in the second SIB.

[0326] One implementation: The first terminal treats the first indication information as "not barred", including: the first terminal treats the first indication information as "not barred" and assesses whether the first cell can be regarded as an acceptable cell;

[0327] One implementation: The first SIB and the second SIB can be the same SIB, for example: SIB1;

[0328] In one embodiment, the first instruction information and the first terminal can be one of the following combinations:

[0329] Combination 1: The first indication information is: cellBarredRedCap1Rx; the first terminal is a RedCap UE that only supports 1Rx branch (i.e., does not support 2Rx branch);

[0330] Combination 2: The first indication information is: cellBarredRedCap2Rx; the first terminal is a RedCap UE that supports the 2Rx branch;

[0331] Combination 3: The first indication information is: cellBarred-eRedCap1Rx; the first terminal is an eRedCap UE that only supports 1Rx branch (i.e., does not support 2Rx branch);

[0332] Combination 4: The first indication information is: cellBarred-eRedCap2Rx; the first terminal is an eRedCap UE that supports the 2Rx branch;

[0333] Combination 5: The first indication information is: cellBarred2RxXR; the first terminal is a 2RxXR UE. When cellBarred2RxXR is carried by the first SIB, it is considered that the first indication information is set to "barred"; when cellBarred2RxXR is not carried by the first SIB, it is considered that the first indication information is set to "not barred"; under this combination, the first terminal regards the first indication information as set to "not barred (i.e., not barred)", which can also be expressed as the first terminal ignoring the received first indication information.

[0334] The second instruction message can be barringExemptEmergencyCall.

[0335] The IE name of the first instruction information, the IE name of the second instruction information, and the type of the first terminal, as well as their corresponding meanings / purposes, comply with the provisions of TS38.331 and TS38.304; this application embodiment will not repeat them.

[0336] The first cell state being indicated as "barred" and the first terminal considering the cell state of the first cell as "barred" means that, without considering the second indication information, the first cell state being indicated as "barred" and the first terminal considering the cell state as "barred".

[0337] The embodiments of this application are not only applicable to 5G systems, but also to future 6G or 7G systems.

[0338] In this embodiment, the UE determines the value of the first indication information based on the second indication information received from the first cell, and determines whether the first cell meets the acceptable cell condition based on the value of the first indication information and the mechanism specified in the protocol (e.g., all A additional indications). If it does, the UE can select the first cell to camp on in order to initiate an emergency call when needed. This embodiment avoids the misjudgment caused by the existing mechanism that only considers a portion of the A indications to determine whether the first cell meets the acceptable cell condition.
