All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be understood that the technical solutions of the embodiments of the present invention can be applied to various communication systems, for example: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), a Long Term Evolution (Long Term Evolution, LTE) System, an LTE Frequency Division Duplex (FDD) System, an LTE Time Division Duplex (TDD), a Universal Mobile Telecommunications System (UMTS) or a Worldwide Interoperability for Microwave Access (WiMAX) communication System, a 5G System, or a New Radio (NR) System.

A Terminal device (UE), which may also be referred to as a Mobile Terminal (Mobile Terminal), a Mobile Terminal device, or the like, may communicate with at least one core Network via a Radio Access Network (RAN, for example), where the Terminal device may be a Mobile Terminal, such as a Mobile phone (or a "cellular" phone) and a computer having the Mobile Terminal, such as a portable, pocket, handheld, computer-embedded or vehicle-mounted Mobile device, and may exchange languages and/or data with the Radio Access Network.

The network device is a device deployed in a radio access network device for providing an information configuration function, and the network device may be a Base Station, where the Base Station may be a Base Transceiver Station (BTS) in GSM or CDMA, a Base Station (NodeB) in WCDMA, an evolved Node B (eNB or e-NodeB) in LTE, a 5G Base Station (gNB) in a subsequent evolved communication system, and a network-side device in the subsequent evolved communication system, but the term does not limit the protection scope of the present invention.

It should be noted that, when describing a specific embodiment, the sequence number of each process does not mean the execution sequence, and the execution sequence of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiment of the present invention.

The following description will first be made with reference to fig. 1, where the method is applied to a terminal device for determining an access cell in a non-standalone non-public network.

It should be noted that, the device for implementing the method for determining an access cell in a non-standalone non-public network according to the embodiment of the present invention may be a terminal device with access group capability, for example, a terminal device supporting access to a specific access group. In addition, the Access Group in the embodiment of the present invention may include, but is not limited to, a Closed Access Group (CAG).

Fig. 1 illustrates an access cell determination method in a non-standalone non-public network, which is applied to a terminal device according to an embodiment of the present invention. As shown in fig. 1, the method may include the steps of:

step 101, determining a candidate cell allowing the terminal device to access based on the target access group information.

The target access group information includes at least one of access group information of the terminal device and access group information of a cell.

The access group information of the terminal device may include information (e.g., an access group list) for determining an access group to which the terminal device belongs, such as identification information of the access group to which the terminal device belongs. In addition, the access group information of the terminal device may further include at least one of frequency point information corresponding to an access group to which the terminal device belongs and cell information and the like belonging to the access group to which the terminal device belongs.

The access group information of the cell may be information of an access group to which the cell is broadcasted by the cell scanned by the terminal device, such as identification information of the access group to which the cell belongs, identification information of other members in the access group to which the cell belongs, and the like.

When a cell belongs to an access group, the cell may be referred to as a member cell of the access group. Similarly, when a terminal device belongs to an access group, the terminal device may be referred to as a member device of the access group. Also, one access group may include a plurality of members, and one member may also belong to a plurality of access groups.

Optionally, before step 101, the method for determining an access cell in a non-standalone non-public network according to the embodiment of the present invention may further include: receiving configuration information from a network device, wherein the configuration information is used for configuring access group information of the terminal device, and the access group information of the terminal device comprises information used for determining an access group to which the terminal device belongs.

For example, the network device may configure the terminal device with an access group list to which the terminal device belongs, such as that the UE belongs to access group 1 and access group 2; additionally, the network device may configure the terminal device with the cell and/or frequency point corresponding to the access group to which the terminal device belongs, for example, configure the member cell of the access group 1 to include cell 1 and cell 2, and configure the member cell of the access group 2 to include cell 3, and so on; or, configuring the frequency points corresponding to the access group 1 to include the frequency point 1 and the frequency point 2, and configuring the frequency points corresponding to the access group 2 to include the frequency point 3, and so on.

And 102, selecting a cell from the candidate cells as an access cell of the terminal equipment.

When the candidate cells are different, the manner of selecting the access cell and the type of service acquired after accessing the cell may be different, which will be described in the following specific examples, and will not be described herein again.

Optionally, before step 101, the terminal device may scan accessible frequency points or cells based on its own capability, and scan for one or more cells.

On this basis, the procedure of determining candidate cells in step 101, how to select an access cell after determining the candidate cells, and what type of service (normal service or limited service) to acquire after accessing the cell will be described below by way of three examples.

First example

In a first example, the network device configures an access group list to which the terminal device belongs in advance for the terminal device, that is, the terminal device belongs to at least one access group.

In an implementation manner of the first example, the step 101 may include: and when the scanned cell is determined to belong to the access group to which the terminal equipment belongs based on the target access group information, determining the scanned cell as a first candidate cell allowing the terminal equipment to access.

Whether the scanned cell belongs to the access group to which the terminal device belongs or not can be determined by at least one of the access group information of the terminal device and the access group information broadcasted by the scanned cell.

In another implementation manner of the first example, if the access group information of the terminal device, configured by the network device to the terminal device, includes frequency point information corresponding to the access group to which the terminal device belongs, before step 101, the terminal device may determine a target frequency point to be scanned according to the access group information of the terminal device, and the target frequency point may only include a frequency point corresponding to a cell belonging to the access group to which the terminal device belongs.

Further, after the target frequency point is determined, only the target frequency point may be scanned, and after at least one cell is scanned by scanning the target frequency point, whether the scanned cell belongs to the access group of the terminal device may be determined by comparing access group identification information in access group information broadcast by the at least one cell with whether identification information of the at least one access group to which the terminal device belongs is consistent.

That is, the terminal device may only scan the frequency points corresponding to the member cells of the access group to which the terminal device belongs. For example, if the terminal device belongs to access group 1, and the member cells of access group 1 include cell 1 (corresponding to frequency point 1) and cell 2 (corresponding to frequency point 2), then only frequency point 1 and frequency point 2 are scanned.

In this embodiment, on one hand, since the terminal device only scans a small number of target frequency points, the scanning range of the terminal device can be reduced, and thus the power consumption of the terminal device is reduced. On the other hand, the scanned target frequency point may only include a frequency point corresponding to a cell belonging to the access group to which the terminal device belongs, so that the probability that the scanned cell is a member cell of the access group of the terminal device may be increased, and thus the first candidate cell that the terminal device may access may be found more quickly.

In another implementation manner of the first example, if the access group information of the terminal device configured by the network device to the terminal device includes cell information belonging to an access group to which the terminal device belongs, before step 101, the terminal device may determine a target cell to be scanned according to the access group information of the terminal device, and the target cell may only include cells belonging to the access group to which the terminal device belongs.

That is, the terminal device may only scan the member cells of the access group to which the terminal device belongs. For example, if the terminal device belongs to access group 1, and the member cells of access group 1 include cell 1 (corresponding to physical cell 1 (identified as PCI1) and cell 2 (corresponding to physical cell 2 (identified as PCI 2)), then the terminal device scans only physical cell 1 and physical cell 2 corresponding to identification PCI1 and PCI2, respectively.

In this embodiment, on the one hand, since only a small number of target cells are scanned, the scanning range of the terminal device can be reduced, thereby reducing the power consumption of the terminal device. On the other hand, because the scanning target cell may only include the cell belonging to the access group to which the terminal device belongs, the probability that the scanned cell is a member cell of the access group of the terminal device may be increased, and thus the first candidate cell accessible to the terminal device may be found more quickly.

Further, the method shown in fig. 1 may further include: and when the scanned cell does not belong to the access group to which the terminal equipment belongs, prohibiting the terminal equipment from accessing the scanned cell or the frequency point corresponding to the scanned cell.

That is, the terminal device considers other cells outside the member cell of the access group to which the terminal device belongs as cells to which access is prohibited. For example, if the terminal device belongs to access group 1, but the Cell 1 scanned by the terminal device does not belong to access group 1, the terminal device considers that the Cell 1 is a Cell prohibited from accessing (Barred Cell).

Or the terminal device considers that the frequency points corresponding to other cells outside the member cell of the access group to which the terminal device belongs are the frequency points which are forbidden to be accessed. For example, if the terminal device belongs to the access group 1, and the member cells of the access group 1 include a cell 1 (corresponding to a Frequency point 1) and a cell 2 (corresponding to a Frequency point 2), the terminal device considers that other Frequency points except the Frequency point 1 and the Frequency point 2 are Frequency points (Barred Frequency) which are not accessed; for another example, if the terminal device belongs to the access group 1 and the cell 1 (corresponding to the frequency point 1) scanned by the terminal device does not belong to a member of the access group 1, the terminal device considers that the frequency point 1 is a frequency point prohibited from being accessed.

Still further, the method shown in fig. 1 may further include: and determining the time for forbidding the terminal equipment to access the access object corresponding to the scanned cell. Wherein the time may be agreed upon by the network device configuration and/or protocol.

For example, when the terminal device considers that other cells except for the member cell of the access group to which the terminal device belongs are cells prohibited from accessing, further, the terminal device may set a duration for prohibiting accessing the cell, such as 300 seconds, or always prohibiting (infinite), according to a configuration or a protocol convention of the network device.

For another example, when the terminal device considers that the frequency point corresponding to the other cell except the member cell of the access group to which the terminal device belongs is the cell prohibited from accessing, further, the terminal device may set a duration for prohibiting accessing the frequency point according to a network device configuration or a protocol convention, for example, 300 seconds, or always prohibited (infinite).

It will be appreciated that the first example is intended to illustrate that a terminal device may only be allowed to access member cells of the access group to which the terminal device belongs, and not non-member cells of the access group to which the terminal device belongs. As the name implies, a non-member cell of an access group is a cell that is not a member of the access group.

Further, on the basis of the first example, the step 102 may include: and selecting a suitable cell from the first candidate cells as an access cell of the terminal equipment.

Wherein the suitable cell may be a cell satisfying the following condition:

the Signal quality satisfies a preset condition, and the Signal quality may include at least one of Reference Signal Receiving Power (RSRP) and Reference Signal Receiving Quality (RSRQ);

preset System Information can be obtained by the terminal device, that is, the terminal device can obtain necessary System Information of the cell, and the System Information may include a Management Information Base (MIB) and a System Information Block 1 (SIB 1); and

the cell is not barred from access (e.g., the cellbar IE of the cell takes the value notgarred), and so on.

If no suitable cell exists in the first candidate cells, the terminal device returns to step 101 to continue scanning to determine the first candidate cells.

Second example

In a second example, the network device configures, in advance, an access group list to which the terminal device belongs to the terminal device, that is, the terminal device belongs to at least one access group.

Optionally, in an implementation manner of the second example, the step 101 may include: and when the scanned cell is determined to belong to the access group to which the terminal equipment belongs based on the target access group information, determining the scanned cell as a first candidate cell allowing the terminal equipment to access.

That is, the network device may use the member cell of the access group to which the network device belongs as a cell that can obtain normal service (normal service). For example, if the terminal device belongs to access group 1 and the cell 1 scanned by the terminal device does not belong to access group 1, the terminal device cannot regard the cell 1 as a cell that can acquire normal service (e.g., the terminal device cannot set cell 1 as "suitable cell"); for another example, if the terminal device belongs to the access group 1 and the cell 2 scanned by the terminal device belong to the access group 1, the cell 1 and the cell 2 may be regarded as cells that can obtain normal services, and other cells that do not belong to the access group 1 may not be regarded as cells that can obtain normal services (e.g., the terminal device may set the cell 1 and the cell 2 as "capable cells" and may not set the cell 1 and the cell 2 as "capable cells" for other cells).

Further, the determining, when it is determined that the scanned cell belongs to the access group to which the terminal device belongs based on the target access group information, the scanned cell as a first candidate cell allowing the terminal device to access may include: when the scanned cell belongs to an access group to which the terminal equipment belongs and meets a first preset condition, determining the scanned cell as a first candidate cell allowing the terminal equipment to access; wherein the first preset condition comprises: the terminal equipment receives first indication information from network equipment, wherein the first indication information is used for indicating that the terminal equipment is allowed to access the scanned cell.

That is, when the scanned cell belongs to a certain access group, the terminal device also belongs to the access group, and the terminal device receives the first indication information from the network device to indicate that the terminal device can access the cell, the UE considers the cell as an accessible cell. For example, if the access group information broadcasted by the Cell 1 indicates that the Cell 1 belongs to the access group 1, and the terminal device determines that the terminal device also belongs to the access group 1 according to the access group information of the terminal device, then, when the network side indicates that the terminal device can access the Cell 1, the terminal device determines the Cell 1 as a candidate Cell that can be accessed (for example, the Cell 1 is set as a suitable Cell or an acceptable Cell).

Optionally, in another implementation manner of the second example, the method shown in fig. 1 may further include: and when the scanned cell meets a second preset condition, prohibiting the terminal equipment from accessing the scanned cell or the frequency point corresponding to the scanned cell.

Wherein the second preset condition comprises: and the scanned cell belongs to a second access group to which the terminal equipment belongs, and the terminal equipment receives second indication information from network equipment, wherein the second indication information is used for indicating that the terminal equipment is forbidden to access the scanned cell.

That is to say, although the cell scanned by the terminal device is a member cell of the access group to which the terminal device belongs, when the network device indicates that the terminal device is prohibited from accessing the cell through the second indication information, the terminal device regards that the cell is a cell prohibited from accessing or a frequency point corresponding to the cell is a frequency point prohibited from accessing.

For example, the access group information broadcasted by the Cell 1 indicates that the Cell 1 belongs to the access group 1, and the terminal device determines that the terminal device also belongs to the access group 1 according to the access group information of the terminal device, but when the network device indicates, through the second indication information, that the terminal device in the access group 1 is prohibited from accessing the member cells of the access group 1, the terminal device considers that the Cell 1 is a Cell (Barred Cell)) which is prohibited from accessing, or the terminal device considers that the frequency point corresponding to the Cell 1 is a frequency point (Barred frequency) which is prohibited from accessing.

For example, the terminal device may set a time duration for prohibiting access to the cell, such as 300 seconds, or always prohibited (infinite), according to the network device configuration or protocol convention.

For another example, the terminal device may set a time duration for prohibiting access to the frequency point, for example, 300 seconds, or always prohibited (infinite), according to the network device configuration or protocol convention.

Optionally, in another implementation manner of the second example, the step 101 may include: and when the scanned cell meets a third preset condition, determining the scanned cell as a second candidate cell allowing the terminal equipment to access.

As a possible case, the third preset condition includes that the scanned cell does not belong to any access group to which the terminal device belongs. This scenario is intended to illustrate that a terminal device may acquire a restricted service by accessing a cell that does not belong to the access group to which the terminal device belongs.

More specifically, the third preset condition includes: the scanned cell is a cell set to a designated purpose, the scanned cell belongs to a third access group, the terminal device does not belong to the third access group, and the terminal device receives third indication information from a network device, wherein the third indication information is used for indicating that a device which does not belong to the third access group is allowed to access the cell belonging to the third access group.

For example, cell 1 scanned by the terminal device is set to be accessed For a designated purpose, For example, cell 1 indicates that "cell reserved For Other Use" takes a value of "true"; meanwhile, the access group information broadcasted by the cell 1 shows that the cell 1 belongs to the access group 1, but the terminal equipment judges that the terminal equipment does not belong to the access group 1 according to the access group information of the terminal equipment; furthermore, the terminal device receives the third indication information from the network, which indicates that the cell 1 is accessible to the terminal device not belonging to the access group to which the cell 1 belongs (e.g., the third indication information indicates that the cell 1 allows access to other terminal devices except for members of the access group 1). Then, the terminal device may determine Cell 1 as a candidate Cell from which the restricted service can be acquired (e.g., set Cell 1 as an acceptable Cell).

As another possible case, the third preset condition may include that the scanned cell belongs to at least one access group to which the terminal device belongs. This scenario is intended to illustrate that a terminal device may also acquire a restricted service by accessing a cell belonging to an access group to which the terminal device belongs.

Optionally, in another implementation manner of the second example, the method shown in fig. 1 may further include: and when the scanned cell meets a fourth preset condition, prohibiting the terminal equipment from accessing the scanned cell or a frequency point corresponding to the scanned cell.

As a case, the fourth preset condition specifically includes: the scanned cell is a cell set to a designated purpose, the scanned cell belongs to a fourth access group, and the terminal device does not belong to the fourth access group.

For example, cell 1 scanned by the terminal device is set to be access For a specific Use (e.g., cell 1 indicates that "cell reserved For Other Use" takes a value of "true"); meanwhile, the access group identifier broadcasted by the cell 1 received by the terminal device is not the identifier of the access group to which the terminal device belongs, and then the terminal device considers that the cell 1 is a cell (barred cell) which is forbidden to access.

As another case, the fourth preset condition includes: the scanned cell is a cell set to a designated purpose, the scanned cell belongs to a fourth access group, the terminal device does not belong to the fourth access group, and the terminal device receives fourth indication information from a network device, wherein the fourth indication information is used for indicating that a device which does not belong to the fourth access group is forbidden to access the cell belonging to the fourth access group.

For example, cell 1 scanned by the terminal device is set to be access For a specific Use (e.g., cell 1 indicates that "cell reserved For Other Use" takes a value of "true"); meanwhile, the access group identifier (access group 1) broadcasted by the cell 1 received by the terminal equipment is not the identifier of the access group (access group 2) to which the terminal equipment belongs; and if the terminal device receives the fourth indication information from the network device and indicates that the device not belonging to the access group 1 of the Cell 1 is prohibited from accessing the Cell 1, the terminal device considers that the Cell 1 is a Barred Cell (Barred Cell).

This case is intended to illustrate that the terminal device considers that the cells other than the member cells that do not belong to the access group to which the terminal device belongs are cells to which access is prohibited, or that the frequency points corresponding to the cells other than the member cells that do not belong to the access group to which the terminal device belongs are frequency points to which access is prohibited.

Optionally, in another implementation manner of the second example, the step 102 may include: and selecting a suitable (able) cell from the first candidate cells as an access cell for the terminal equipment to acquire normal service.

Wherein the suitable cell may be a cell satisfying the following condition:

the signal quality meets a preset condition;

the preset system information can be acquired by the terminal equipment; and

access is not barred.

Optionally, in another implementation manner of the second example, if there is no suitable cell in the first candidate cell, the step 102 may further include: and selecting an acceptable (acceptable) cell from the second candidate cells as an access cell for the terminal equipment to acquire the limited service.

That is, on the basis of the second example, the process of selecting the access cell by the terminal device may include two stages, a first stage of selecting one cell from the first candidate cells to obtain normal service; and a second stage of selecting one cell from the second candidate cells to acquire the limited service if no suitable cell exists in the first candidate cells. Further, if there is no acceptable cell in the second cell, the scanning is continued.

In summary, in the second example, the terminal device may only use the member cell of the access group to which the terminal device belongs as the cell for acquiring the normal service (normal service), but may use the member cell of the access group to which the terminal device belongs as the cell for acquiring the limited service (limited service), or may use the cell that does not belong to the access group to which the terminal device belongs as the cell for acquiring the limited service (limited service).

For example, if the terminal device belongs to access group 1, but the scanned cell 1 does not belong to access group 1, the terminal device cannot treat cell 1 as a cell that can acquire normal service (e.g., the terminal device cannot set cell 1 to "suiteable"). For another example, if the terminal device belongs to the access group 1 and the scanned cell 1 and cell 2 also belong to the access group 1, the terminal device may use the cell 1 and cell 2 as cells that can acquire normal services, for example, the terminal device may set the cell 1 and cell 2 as "viable cells" and cannot set the cell 1 and cell 2 as "viable cells" for other cells.

For another example, if the terminal device belongs to the access group 1, but the scanned cell 1 does not belong to the access group 1, the terminal device may use the cell 1 as a cell for acquiring the restricted service (e.g., the terminal device sets the cell 1 to "acceptable cell"); for another example, if the terminal device belongs to the access group 1 and the member cells of the access group 1 include the cell 1 and the cell 2, the terminal device may use other cells except the cell 1 and the cell 2 as the cells for acquiring the restricted service (e.g., the terminal device may set other cells except the cell 1 and the cell 2 as "acceptable cells").

Third example

In a third example, the terminal device may have access group capability, but the network device does not configure the access group to which the terminal device belongs, that is, the terminal device does not belong to any access group. At this time, the target access information includes access group information broadcasted by the cell.

Optionally, in an implementation manner of the third example, step 101 may include: determining whether the scanned cell belongs to at least one access group based on the target access group information; and when the scanned cell does not belong to any access group, determining the scanned cell as a first candidate cell allowing the terminal equipment to access.

For example, when the scanned Cell is a normal Cell (normal Cell), the Cell may be regarded as the first candidate Cell.

Optionally, in another implementation manner of the third example, the method shown in fig. 1 may further include: when the scanned cell meets a fifth preset condition, prohibiting the terminal equipment from accessing the scanned cell or a frequency point corresponding to the scanned cell; wherein the fifth preset condition includes that the scanned cell belongs to a fifth access group.

This embodiment is intended to illustrate that, when a scanned cell belongs to a certain access group, the terminal device considers the cell as a cell prohibited from accessing. For example, if it is shown in the access group information broadcast by the Cell 1 that the Cell 1 belongs to the access group 1, the terminal device considers that the Cell 1 is a Cell (Barred Cell) which is prohibited from accessing, or the terminal device considers that a Frequency point corresponding to the Cell 1 is a Frequency point (Barred Frequency) which is prohibited from accessing.

Still further, in another implementation manner of the third example, the fifth preset condition may further include: the scanned cell is a cell set to a designated purpose.

This embodiment is intended to illustrate that when the terminal device determines that the scanned cell belongs to a specific access group and determines that the cell is set for a specific use access, the terminal device considers the cell as a cell for which access is prohibited. For example, the terminal device detects that the Cell 1 belongs to the access group 1, and a message broadcasted by the Cell 1 shows that a value of "Cell Reserved For other use" is "true", then the terminal device considers that the Cell 1 is a Cell (Barred Cell) which is prohibited from accessing.

Or, still further, in another implementation manner of the third example, the fifth preset condition further includes: the scanned cell is a cell set to a designated purpose, and the terminal device receives fifth indication information from a network device, where the fifth indication information is used to indicate that devices not belonging to the fifth access group are prohibited from accessing the fifth access group.

The embodiment is intended to illustrate that, when the terminal device determines that the scanned cell belongs to a specific access group, determines that the cell is set to be access for a specific purpose, and receives the indication information of the network device indicating that the cell is prohibited from being accessed to a device not belonging to the access group to which the cell belongs, the terminal device considers the cell as a cell prohibited from being accessed. For example, when the terminal device detects that the Cell 1 belongs to the access group 1, and a message broadcasted by the Cell 1 shows that a value of "Cell Reserved for other Use" is "true", and the network side indicates that the Cell 1 prohibits access by a device not belonging to the access group 1 to which the Cell 1 belongs, the terminal device considers that the Cell 1 is a Barred Cell (Barred Cell).

Still further, in another implementation manner of the third example, the method shown in fig. 1 may further include: and determining the time for forbidding the terminal equipment to access the access object corresponding to the scanned cell. Wherein the time may be agreed upon by the network device configuration and/or protocol.

Optionally, in another implementation manner of the third example, step 101 may include:

and when the scanned cell meets a sixth preset condition based on the target access group information, determining the scanned cell as a second candidate cell allowing the terminal equipment to access.

Wherein the sixth preset condition includes that the scanned cell belongs to a sixth access group; or, the sixth preset condition includes that the scanned cell does not belong to any access group.

This embodiment is intended to illustrate that the terminal device may use the scanned normal cell as the second candidate cell for acquiring the restricted service, or may use the scanned cell belonging to a certain access group as the second candidate cell for acquiring the restricted service.

Further, in another implementation manner of the third example, the sixth preset condition may further include: the scanned cells are set as the cells of the designated purpose, and the terminal equipment receives sixth indication information from network equipment, wherein the sixth indication information is used for indicating that the equipment which does not belong to the sixth access group is allowed to access the cells belonging to the sixth access group.

This embodiment is intended to illustrate that if the scanned cell is set to be access for a specific purpose, while the terminal device receives that the cell belongs to a specific access group, and the terminal device receives that the indication information on the network side indicates that the cell allows access to devices not belonging to the access group to which the cell belongs, the terminal device considers the cell as an access-allowed cell. For example, when the terminal device detects that the Cell 1 belongs to the access group 1, and a message broadcasted by the Cell 1 shows that a value of "Cell Reserved for other Use" is "true", and the network side indicates that the Cell 1 allows a device not belonging to the access group 1 to which the Cell 1 belongs to access, the terminal device considers that the Cell 1 is a Cell (Barred Cell) which allows access.

Optionally, in another implementation manner of the third example, the step 102 may include: and selecting a suitable (able) cell from the first candidate cells as an access cell for the terminal equipment to acquire normal service.

Wherein the suitable cell may be a cell satisfying the following condition:

the signal quality meets a preset condition;

the preset system information can be acquired by the terminal equipment; and

access is not barred.

Optionally, in another implementation manner of the third example, if there is no suitable cell in the first candidate cell, the step 102 may further include: and selecting an acceptable (acceptable) cell from the second candidate cells as an access cell for the terminal equipment to acquire the limited service.

That is to say, on the basis of the third example, the process of selecting the access cell by the terminal device may also include two stages, in the first stage, one cell is selected from the first candidate cells to obtain normal service; and a second stage of selecting one cell from the second candidate cells to acquire the limited service if no suitable cell exists in the first candidate cells. Further, if there is no acceptable cell in the second cell, the scanning is continued.

In summary, in the third example, the terminal device may use a normal cell (not belonging to any access group) as a cell for acquiring a normal service (normal service), or may use a normal cell or a cell belonging to a certain access group as a cell for acquiring a limited service (limited service).

The method for determining the access cell in the non-independent non-public network provided by the embodiment of the invention can determine the candidate cells firstly, and then select one cell from the candidate cells as the access cell of the terminal equipment, so that the specific terminal equipment in the non-independent non-public network can be ensured to be correctly accessed into the specific cell to obtain the service. In addition, according to the scheme, the cell scanning range can be reduced according to at least one of the frequency point information corresponding to the access group to which the terminal equipment additionally configured belongs and the cell information belonging to the access group to which the terminal equipment belongs, so that the power consumption of the terminal equipment can be reduced.

The cell information of the access group to which the terminal device belongs may be used for the terminal device to determine a target cell that the terminal device needs to scan, and the target cell may only include a cell belonging to the access group to which the terminal device belongs, which may also reduce the scanning range of the terminal device, thereby reducing the power consumption of the terminal device.
