For ease of understanding, some of the matters referred to in the examples of the present application are explained below:

introduction of slices or network slices:

currently, to identify end-to-end Network slices, each Network Slice may be uniquely identified by a Single Network Slice Selection Assistance Information (S-NSSAI), each of which may include a Slice/service Type (SST) and a Slice Differentiator (SD).

A Network slice always consists of a Radio Access Network (RAN) part and a Core Network (CN) part. The support of network slicing relies on the following principles: traffic of different slices is handled by different Protocol Data Unit (PDU) sessions. The network side may implement different network slices by scheduling and providing different L1/L2 configurations.

In New Radio (NR) Release 15, R15, a User Equipment (UE) does not know whether a RAN supports a certain network slice when attempting to access the RAN. The UE may carry one or more requested NSSAIs (i.e., requested NSSAIs) in a Radio Resource Control (RRC) connection setup complete message, including the S-NSSAIs of the network slice that the UE wants to register.

The RAN selects the appropriate Access and Mobility Management Function (AMF) based on the requested NSSAI provided by the UE, which may be selected if the RAN cannot make a selection, e.g., the UE does not provide requested NSSAI or the UE provides requested NSSAI but the RAN does not find an AMF matching its capabilities. The AMF determines which requested S-NSSAIs may be allowed based on the requested NSSAIs provided by the UE and the slice subscription information (e.g., the subscribed NSSAIs) of the UE and the RAN-side slice configuration, respectively.

Referring to fig. 1, fig. 1 is a structural diagram of a network system to which the embodiment of the present application is applicable, and as shown in fig. 1, the network system includes a terminal Device 11, an access network-side Device 12, and a core network-side Device 13, where the terminal Device 11 may be a user-side Device such as a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device), and it should be noted that a specific type of the terminal Device 11 is not limited in the embodiment of the present application. The access network side device 12 may include at least one of an access network side device and a core network side device, where the access network side device may be a base station, for example: macro station, LTE eNB, 1G NR NB, gNB, etc., or small stations, such as Low Power Node (LPN) pico, femto, etc., or Access Point (AP). The base station may also be a network node formed by a Central Unit (CU) and a plurality of TRPs managed and controlled by the CU. It should be noted that the specific type of the access network-side device 12 is not limited in the embodiment of the present application.

The information processing method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

The embodiment of the application provides an information processing method, which is applied to a non-Access Stratum (NAS) of a terminal device. Referring to fig. 2, fig. 2 is a flowchart of an information processing method provided in an embodiment of the present application, and as shown in fig. 2, the method includes the following steps:

step 201, a non-access layer of a terminal device transmits slice use information to an access layer of the terminal device; wherein the slice usage information is generated from slice assistance information, the slice assistance information being used to assist the non-access stratum in selecting slices.

In this embodiment, the Slice auxiliary information may be used to indicate part or all of slices (i.e., slices) supported by the network side, or may be used to indicate part or all of slices that the network side allows the terminal device to access, so as to assist the non-access stratum in performing Slice selection. For example, if the slices supported by the network side are slice a, slice b, slice c, and slice d, the slice auxiliary information may be used to indicate slice a, slice b, slice c, and slice d, or if the slices allowed to be accessed by the terminal device by the network side are slice b, slice c, and slice d, the slice auxiliary information may be used to indicate slice b, slice c, and slice d. The slice auxiliary information may be preconfigured or configured by the core network side device.

The slice usage information may be used to indicate a slice selected by the non-access stratum, and specifically, the non-access stratum may perform slice selection based on the slice indicated by the slice auxiliary information, that is, the non-access stratum may generate the slice usage information based on the slice auxiliary information. For example, the slice auxiliary information may indicate the slice b, the slice c, and the slice d, and the slice use information may indicate the slice b if the slice b is selected by the non-access layer.

In step 201, the non-access stratum of the terminal device transmits slice usage information to the access stratum of the terminal device, so that the access stratum of the terminal device can perform cell selection or slice routing information reporting based on the slice usage information. Because the terminal equipment can acquire the slices supported by the network side based on the slice auxiliary information, the slice using information is generated based on the slice auxiliary information, the accuracy of the slice selected by the terminal equipment can be improved, and the reliability of slice access is further improved.

Optionally, the slicing assistance information may include at least one of:

a correspondence between a slice and a slice index, or a slice index list;

the corresponding relation between the slices and the slice combination indexes, or a slice combination index list;

the corresponding relation between the slice and the cell identifier, or a cell identifier list;

the corresponding relation between the slice and the tracking area identifier, or a tracking area identifier list;

the corresponding relation between the slices and the routing indexes of the core network functions or a routing index list of the core network functions;

the corresponding relation between the slices and the frequency points or the frequency point list;

a correspondence of slices and frequency bands, or a frequency band list.

In this embodiment, the slice auxiliary information may include information corresponding to one or more slices. For ease of understanding, the present embodiment is described below with reference to examples:

a list of Slice indices or a correspondence for slices and Slice indices (i.e., Slice to Slice Index). For example, the slices supported by the network side are slice _ a, slice _ b, slice _ c, slice _ d, and slice _ e, the corresponding slice indexes (i.e., slice indexes) are 1,2,3, 4, and 5, respectively, if the UE is allowed to access slice _ b, slice _ c, and slice _ d, the correspondence between the slice sent by the network side to the UE and the slice index may be { < slice _ b,2>, < slice _ c,3>, < slice _ d,4> }, or the slice index list sent by the network side to the UE may be {2,3,4 }. Note that different slices may correspond to the same slice index, and the same slice may also correspond to different slice indexes.

Optionally, the network side may further generate a slice index that does not correspond to any slice, and the correspondence between the slice and the slice index may further include a slice index that does not correspond to any slice, so as to improve security of slice access. For example, none of the slice indexes 7, 8, and 9 corresponds to any slice, and at this time, the slice sent by the network side to the UE and the slice index may correspond to { < slice _ b, (2,7) >, < slice _ c, (3,9) >, < slice _ d, (4,7,9) > }, or the slice index list sent by the network side to the UE may be { (2,7), (3,9), (4,7,9) }.

A correspondence relationship for Slice and Slice Combination Index (i.e., Slice to Slice Combination Index), or a Slice Combination Index list. For example, the network configures that the index corresponding to the slice combination < slice _ a, slice _ b > is 1, the index corresponding to the slice combination < slice _ a, slice _ c > is 2, and the index corresponding to the slice combination < slice _ b, slice _ c, slice _ d > is 3. If the UE is allowed to access slice _ a and slice _ b, the correspondence between the slice and the slice combination index sent by the network side to the UE may be { < slice _ a, (1,2) >, < slice _ b, (1,3) > }, or the slice combination index list sent by the network side to the UE may be { (1,2), (1,3) }; if the UE is allowed to access slice _ a, slice _ b, and slice _ d, the correspondence between the slice and the slice combination index sent by the network side to the UE may be { < slice _ a, (1,2) >, < slice _ b, (1,3) >, < slice _ d, (3) >, or the slice combination index list sent by the network side to the UE may be { (1,2), (1,3), (3) }.

For the correspondence of slices and cell identities (i.e. cell ids) or a list of cell identities. For example, cell id1 (i.e., a cell with a cell id of 1) supports accesses of slice _ a and slice _ b, cell id2 supports accesses of slice _ a and slice _ c, and cell id3 supports accesses of slice _ b, slice _ c, and slice _ d, and if the UE is allowed to access slice _ a and slice _ b, the correspondence between the slice sent by the network side to the UE and the cell id may be { < slice _ a, (cell id1, cell id2) >, < slice _ b, (cell id1, cell id3 }, or the cell id list sent by the network side to the UE may be { (cell id1, cell id2), (cell id1, cell 3) }; if the UE is allowed to access slice _ a, slice _ b, and slice _ d, the correspondence between the slice sent by the network side to the UE and the cell identifier may be { < slice _ a, (cell id1, cell id2) >, < slice _ b, (cell id1, cell id3) >, < slice _ d, (cell id3) >, or the cell identifier list sent by the network side to the UE may be { (cell id1, cell id2), (cell id1, cell id3), (cell id3) }.

A list of Tracking Area identifications or correspondences for slice and Tracking Area (TA) identifications. For example, TA1 supports access of slice _ a and slice _ b, TA2 supports access of slice _ a and slice _ c, and TA3 supports access of slice _ b, slice _ c, and slice _ d, if the UE is allowed to access slice _ a and slice _ b, the correspondence between the slice and the tracking area identifier sent by the network side to the UE may be { < slice _ a, (TA1, TA2) >, < slice _ b, (TA1, TA3) >, or the tracking area identifier list sent by the network side to the UE may be { (TA1, TA2), (TA1, TA3) }. If the UE allows accessing slice _ a, slice _ b, and slice _ d, the slice sent to the UE by the network side and the tracking area identifier have a corresponding relationship of { < slice _ a, (TA1, TA2) >, < slice _ b, (TA1, TA3) >, < slice _ d, (TA3) >, or the tracking area identifier list sent to the UE by the network side is { (TA1, TA2), (TA1, TA3), (TA3) }.

For the correspondence relationship between the slices and the core network function routing identifiers (i.e. slice to slice routing index), or the core network function routing index list. For example, the network side configures < AMFm, …, AMFn > or < AMF SETm, …, AMF SETn > or < AMF SETa, …, AMF SETb, AMFm, …, AMFn, … > as a slice routing group, the corresponding core network function routing index (i.e. slice routing index) is 1, and so on, different slice routing indexes correspond to different slice routing groups, and different slice routing groups can support the same slice. If the UE is allowed to access slice _ a and slice _ b, the correspondence between the slice sent to the UE by the network side and the core network function routing index may be { < slice _ a, (1,2) >, < slice _ b, (4) >, or the core network function routing index list sent to the UE by the network side may be { (1,2), (4) }, where slice routing index with a value of 1 and slice routing index with a value of 2 both include AMFk or AMF SETk, where AMFk or AMF SETk supports service slice _ a, and similarly, the meaning of the relationship between slice _ b and slice routing index ═ 4 may be known.

For the correspondence between slices and Frequency bins (i.e., Slice to Frequency Number) or the above Frequency bin list, for example, the slices supported by the network side are Slice _ a and Slice _ b, and the corresponding Frequency bins (i.e., Frequency Number) are (FN1, FN2, FN3), (FN4, FN5), if the UE is allowed to access Slice _ a and Slice _ b, the correspondence between slices and Frequency bins sent to the UE by the network side is { < Slice _ a, (FN1, FN2, FN3), < Slice _ b, (FN4, FN5) >, or the Frequency bin list sent to the UE by the network side may be { (FN1, FN2, FN3), (FN4, FN5) }. It should be noted that different slices may correspond to the same frequency bin set.

For the slice to frequency band correspondence or frequency band list. For example, slices supported by the network side are slice _ a, slice _ b, and slice _ c, and corresponding frequency bands (i.e., frequency bands) are (FB1, FB2), FB3, (FB1, FB4, FB5), if the UE is allowed to access slice _ b and slice _ c, the correspondence between the slice and the frequency band sent by the network side to the UE is { < slice _ b, (FB3) >, < slice _ c, (FB1, FB4, FB5) >, or the frequency band list sent by the network side to the UE is { (FB3), (FB1, 4, FB5) }. It should be noted that different slices may correspond to the same frequency band set.

Optionally, the slicing assistance information may be configured at any granularity as follows:

public Land Mobile Network (PLMN);

tracking the area;

registration Area (RA).

In this embodiment, the slicing assistance information is configured according to the granularity of the PLMN, that is, each PLMN corresponds to one set of slicing assistance information. The slice auxiliary information is configured according to the granularity of the tracking areas, that is, each tracking area corresponds to a set of slice auxiliary information. The slice auxiliary information is configured according to the granularity of the registration areas, that is, each registration area corresponds to a set of slice auxiliary information.

For example, the correspondence between slices and slice indexes under PLMN 1 may be { < slice _ a,1>, < slice _ b,2>, < slice _ c,3>, < slice _ d,4>, < slice _ f,5> }, and the correspondence between slices and slice indexes under PLMN2 may be { < slice _ f,2>, < slice _ g,3>, < slice _ h,4>, < slice _ i,5 >.

Optionally, the slice usage information may include at least one of:

slice indexing;

slice combination indexing;

a cell identity;

tracking an area identifier;

core network function routing index;

frequency point information;

frequency band information.

In this embodiment, the slice use information may correspond to the slice auxiliary information. For example, if the slice assistance information includes a correspondence between slices and slice indexes or a slice index list, the slice usage information may include the slice indexes; if the slice auxiliary information includes a correspondence between the slice and the slice combination index or a slice combination index list, the slice use information may include the slice combination index; if the slice auxiliary information includes a corresponding relationship between a slice and a cell identifier or a cell identifier list, the slice usage information may include the cell identifier; if the slice auxiliary information includes a correspondence between a slice and a tracking area identifier or a tracking area identifier list, the slice usage information may include the tracking area identifier; if the slice auxiliary information includes a correspondence between a slice and a core network function routing index or a core network function routing index list, the slice use information may include the core network function routing index; if the auxiliary slicing information includes the correspondence between the slices and the frequency points or the frequency point list, the slice use information may include frequency point information; if the slice auxiliary information includes a correspondence between a slice and a frequency band or a frequency band list, the slice usage information may include frequency band information.

It should be noted that the slice usage information transmitted by the non-access stratum to the access stratum may include slice usage information corresponding to one or more slices. For example, the slice usage information transmitted by the non-access stratum to the access stratum may include slice indexes corresponding to one or more slices, or the slice usage information may include cell identifications corresponding to one or more slices.

For ease of understanding, the present embodiment is described below with reference to examples:

the first condition is as follows: the slice use information may include one or more slice indexes if the slice auxiliary information includes a correspondence between a slice and a slice index or a slice index list (i.e., one or more slice indexes). For example, if the UE selects slice _ b, the slice use information may include a slice index corresponding to slice _ b, i.e. 2 or (2, 7); if the UE selects slice _ b and slice _ c, the slice use information may include a union of slice indexes corresponding to slice _ b and slice _ c, i.e., (2,3) or (2,3,7, 9).

Case two: the slice use information may include one or more slice combination indexes if the slice auxiliary information includes a correspondence relationship between a slice and a slice combination index or a list of slice combination indexes (i.e., one or more slice combination indexes). For example, if the UE selects slice _ a, the slice use information may include a slice combination index corresponding to slice _ a, i.e., (1,2), and if the UE selects slice _ a and slice _ d, the slice use information may include a union of slice combination indexes corresponding to slice _ b and slice _ c, i.e., (1,2, 3).

Case three: the slice use information may include one or more cell identifiers if the slice assistance information includes a correspondence between slices and cell identifiers, or a cell identifier list (i.e., one or more cell identifiers). For example, if the UE selects slice _ a, the slice usage information may include a cell identifier corresponding to slice _ a, that is, (cell id1, cell id 2); if the UE selects slice _ a and slice _ d, the slice use information may include a union of cell ids corresponding to slice _ a and slice _ d, i.e., (cell id1, cell id2, cell id 3).

Case four: the slice usage information may include one or more tracking area identifiers if the slice assistance information includes a correspondence between a slice and a tracking area identifier, or a tracking area identifier list (i.e., one or more tracking area identifiers). If the UE selects slice _ a, the slice usage information may include a TA corresponding to slice _ a, i.e. (TA1, TA 2); if the UE selects slice _ a and slice _ d, the slice usage information may include a union of TAs corresponding to slice _ a and slice _ d, i.e., (TA1, TA2, TA 3).

Case five: if the slice auxiliary information includes a correspondence between a slice and a core network function routing index, or a core network function routing index list (i.e., one or more core network function routing indexes), the slice use information may include one or more core network function routing indexes. For example, if the UE selects slice _ a, the slice usage information may include a core network function routing index corresponding to slice _ a, that is, (1,2), and the UE may further indicate an operation type to the access layer, such as a registration operation or a session operation, information reporting, cell selection, or information reporting and cell selection; if the UE selects slice _ a and slice _ b, the slice use information is the union of the sets of slice routing indexes corresponding to slice _ a and slice _ b, i.e., (1,2, 4).

Case six: if the slice auxiliary information includes a correspondence between slices and frequency points, or a frequency point list (i.e., one or more frequency points), the slice use information may include information about one or more frequency points. If the UE selects slice _ a, the slice use information may include a bin corresponding to slice _ a, i.e. (FN1, FN2, FN 3); if the UE selects slice _ a and slice _ b, the slice use information may include a union of the bins corresponding to slice _ a and slice _ d, i.e. FN1, FN2, FN3, FN4, FN 5.

Case seven: if the slice auxiliary information includes a correspondence between a slice and a frequency band, or a frequency band list (i.e., one or more frequency band information), the slice use information may include one or more frequency band information. For example, if the UE selects slice _ a, the slice usage information may include a frequency band corresponding to slice _ a, that is, (FB1, FB 2); if the UE selects slice _ a and slice _ b, the slice usage information may include a union of the frequency bands corresponding to slice _ a and slice _ d, i.e., (FB1, FB2, FB 3).

In the case where the slice auxiliary information includes a plurality of types of information, the slice information may be a combination of the plurality of types of information. For example, if the slice assistance information is { < slice _ a, (FN1, FN2), (cell id2, cell id5), (slice routing index 1,3), (FB1, FB3) >, < slice _ b, (FN2, FN5), (cell id5), (slice routing index 3), (FB4) > }, when the UE selects slice _ a, the slice usage information may be { (FN1, FN2), (cell id2, cell id5), (slice routing index 1,3), (FB1, FB3) }, and when the UE selects slice _ a and slice _ b, the slice usage information may be { (FN1, FN2, FN5), (cell id2, cell id5), (slice routing index 1, slice 3), (FB1, FB3, 4) }.

In this embodiment, the slice is indicated by at least one of a slice index, a slice combination index, a cell identifier, a tracking area identifier, a core network function routing index, frequency point information, and frequency band information, so that the security of slice access can be improved.

Optionally, the slice usage information transmitted by the non-access stratum to the access stratum may include slice usage information corresponding to a plurality of slices.

For example, the slice usage information transmitted by the non-access stratum to the access stratum may include slice indexes corresponding to a plurality of slices or may include cell identifications corresponding to a plurality of slices.

Optionally, the method may further include:

and acquiring the auxiliary slicing information sent by the core network side equipment.

For example, the terminal device may receive the slice auxiliary information that is specifically sent to the terminal device by the core network side device or receive the slice auxiliary information broadcasted by the core network side device.

Optionally, the method may further include:

and transmitting operation type information to the access stratum, wherein the operation type information is used for indicating an operation type.

In this embodiment, the non-access stratum may further indicate an operation type to the access stratum, so that the access stratum may perform a corresponding operation based on the received slice usage information.

Optionally, the operation type may include at least one of: registering operation, conversation operation, information reporting and cell selection.

The embodiment of the application provides an information processing method, which is applied to an Access Stratum (AS) of terminal equipment. Referring to fig. 3, fig. 3 is a flowchart of another information processing method provided in the embodiment of the present application, and as shown in fig. 3, the method includes the following steps:

301, an access layer of a terminal device receiving slice usage information from a non-access layer of the terminal device; wherein the slice usage information is generated from slice assistance information, the slice assistance information being used to assist the non-access stratum in selecting slices.

Step 302, an access layer of a terminal device sends slice routing information to an access network side device, or selects a cell according to the slice use information; wherein the slice routing information is generated from the slice usage information.

In an embodiment, after receiving the slice usage information, the access layer of the terminal device may generate slice routing information based on the slice usage information and report the slice routing information to the access network side device, so that the access network side device may select an AMF or an AMF SET (i.e., AMF SET) based on the slice routing information. The slice use information is generated based on the slice auxiliary information, so that the accuracy of the slice selected by the terminal equipment can be improved, further, the slice routing information is reported based on the slice use information, and the AMF or AMF set selection rate can be improved.

In another embodiment, after receiving the slice usage information, the access stratum of the terminal device may select an access cell based on the slice usage information, for example, may select a cell supporting a larger number of slices indicated by the slice usage information for access. Because the slice use information is generated based on the slice auxiliary information, the accuracy of the slice selected by the terminal equipment can be improved, and then the cell selection is carried out according to the slice use information, so that the reliability and the efficiency of cell access can be improved.

Optionally, the slicing assistance information may include at least one of:

a correspondence between a slice and a slice index, or a slice index list;

a correspondence of slices and frequency bands, or a frequency band list.

It should be noted that, for the slicing assistance information in this embodiment, reference may be made to the related description of the slicing assistance information in the foregoing embodiment, and details are not described herein to avoid repetition.

Optionally, the slice usage information may include at least one of:

slice indexing;

In an embodiment, a priority of a cell whose intersection of the cell assistance information and the slice usage information is a non-empty set is higher than a priority of a cell whose intersection of the cell assistance information and the slice usage information is an empty set. For example, if the intersection of the cell assistance information and the slice use information of the cell a is 3, the intersection of the cell assistance information and the slice use information of the cell B is (2,3), and the intersection of the cell assistance information and the slice use information of the cell a is an empty set, the priorities of the cell a and the cell B are both higher than the priority of the cell C.

In another embodiment, the priority of the frequency point corresponding to the cell whose intersection of the cell auxiliary information and the slice usage information is a non-empty set is higher than the priority of the frequency point corresponding to the cell whose intersection of the cell auxiliary information and the slice usage information is an empty set. For example, the intersection of the cell auxiliary information and the slice use information of the cell a is 3, the intersection of the cell auxiliary information and the slice use information of the cell B is (2,3), and the intersection of the cell auxiliary information and the slice use information of the cell C is an empty set, so that the priority of the frequency point corresponding to the cell a and the priority of the frequency point corresponding to the cell B are both higher than the priority of the frequency point corresponding to the cell C.

In this embodiment, when the access layer of the terminal device determines that a certain cell is a cell prohibited from being accessed, the access layer of the terminal device may not access the cell any more, or may not access the cell only within the duration of the prohibited access. Similarly, when the access layer of the terminal device determines that the frequency point corresponding to a certain cell is a frequency point prohibited from being accessed, the access layer of the terminal device may not access the frequency point any more, or only access the frequency point within the duration of the prohibited access.

For example, if the intersection of the cell auxiliary information and the slice use information of the cell a is 3, the intersection of the cell auxiliary information and the slice use information of the cell B is (2,3), and the intersection of the cell auxiliary information and the slice use information of the cell C is an empty set, it may be determined that the cell C is a cell prohibited from being accessed, or it may be determined that the frequency point corresponding to the cell C is a frequency point prohibited from being accessed.

Optionally, the duration of the access prohibition is predetermined by a protocol or configured by the network side device.

In this embodiment, the access prohibition duration is used to limit a cell or a frequency point to which access is prohibited. That is, the cell which is forbidden to access in the duration of the forbidden access, or the frequency point which is forbidden to access in the duration of the forbidden access.

For example, if the first type sub-information includes frequency point information, the second type sub-information includes frequency band information, the third type sub-information includes cell id, then, a fourth cell whose intersection of the frequency point information of the cell auxiliary information and the frequency point information of the slice use information is a non-empty set may be obtained first, a fifth cell whose intersection of the frequency band information of the cell auxiliary information and the frequency band information of the slice use information is a non-empty set may be obtained from the fourth cell, an accessed cell may be selected according to the intersection of the cell identifier of the cell auxiliary information of the fifth cell and the cell identifier of the slice use information, for example, the intersection of the cell identity of the cell assistance information and the cell identity of the slice usage information is selected as the fifth cell access of the non-empty set, or selecting a fifth cell with the maximum number of elements of the intersection of the cell identification of the cell auxiliary information and the cell identification of the slice using information for access.

When there are a plurality of fourth cells having the largest number of elements of the intersection of the second type sub information of the cell assistance information and the second type sub information of the slice usage information, one cell may be selected from the plurality of fourth cells for access according to other cell selection parameters, where the cell selection parameters may include, but are not limited to, signal strength of the cell.

In another embodiment, a cell may be selected from a fourth cell in which an intersection of the second type sub-information of the cell assistance information and the second type sub-information of the slice usage information is a non-empty set. When there are a plurality of fourth cells whose intersection of the second type sub information of the cell assistance information and the second type sub information of the slice usage information is a non-empty set, one cell may be selected from the plurality of fourth cells for access according to other cell selection parameters, where the cell selection parameters may include, but are not limited to, signal strengths of the cells.

The present embodiment is described below by way of examples:

if the slice use information includes a plurality of types of information, for example, the slice use information includes frequency point information, core network function routing index, frequency band information, and the like, these pieces of information may be used in combination.

Since the cell auxiliary information can be broadcast by air interface segments, multiple types of information included in the cell auxiliary information can be combined in a cascade manner, for example, whether the frequency point meets the condition is judged first, whether the core network function routing index in the SIB1 meets the condition is judged, and whether the frequency bands in other SIBs meet the condition is judged, so that the cell selection priority is obtained; the cell auxiliary information may also include multiple types of information, for example, the cell id and the core network function routing index are both sent through the SIB1, so that it can be determined whether both the cell id and the core network function routing index satisfy the condition, thereby obtaining the cell selection priority.

For another example, when the intersection of the frequency point information in the cell auxiliary information and the frequency point information in the slice use information is a non-empty set, the cell selection priority is set according to the number of elements in the intersection of the core network function routing index in the cell auxiliary information and the core network function routing index in the slice use information.

For another example, when the intersection of the frequency point information of the cell and the frequency point information in the slice use information is not empty, a cell selection high priority is set for the non-empty set according to the intersection of the core network function routing index in the cell auxiliary information and the core network function routing index in the slice use information.

Optionally, the slice routing information may include at least one of:

core network function routing index;

slice indexing;

slice combination index.

In this embodiment, the slice routing information reported by the access layer may include slice routing information corresponding to one or more slices.

For ease of understanding, the following description will be made with reference to slice routing information for AMF or AMF SET selection by an access network-side device:

the first condition is as follows: the slice routing information contains a slice index.

For example, the slice routing information includes a slice index SET of (2,3,7), a slice index SET corresponding to a slice supported by AMFa or AMF SETa of (1,3), and a slice index SET corresponding to a slice supported by AMFb or AMF SETb of (1,2,3), and without the influence of other parameters (such as an AMF identifier sent by the UE), the access network side device may SET the priority of the AMF or AMF SET according to the number of elements of the intersection of the slice routing information and the slice index corresponding to the slice supported by the AMF or AMF SET, so that the selection of the AMF or AMF SET may be performed according to the priority of the AMF or AMF SET. For example, if the number of elements of the intersection of the slice index corresponding to the slice supported by the AMFb or AMF SETb and the slice routing information is greater than the number of elements of the intersection of the slice index corresponding to the slice supported by the AMFa or AMF SETa and the slice routing information, it may be determined that the priority of the AMFb or AMF SETb is higher than the priority of the AMFa or AMF SETa, and the access network-side device may preferentially select the AMFb or AMFSETb to serve the traffic of the user terminal.

Optionally, the access network side device may first remove the slice index that does not correspond to any slice in the slice routing information, and then perform the above steps.

It should be noted that, if the slice routing information only includes one slice index, or only includes one slice index after removing the slice index that does not correspond to any slice, the access network side device may determine the AMF or AMF SET that supports the slice corresponding to the slice index, and select one of the AMFs or the AMF SET that serves the ue.

Case two: the slice routing information contains a slice combination index.

For example, the slice routing information includes a slice combination index SET of (2,3), a slice combination index SET corresponding to a slice supported by AMFa or AMF SETa of (1,3), and a slice combination index SET corresponding to a slice supported by AMFb or AMF SETb of (1,2,3), and without the influence of other parameters (such as an AMF identifier sent by the UE), the access network side device may SET the priority of AMF or AMFSET according to the number of elements of the intersection of the slice routing information and the slice combination index corresponding to the slice supported by AMF or AMF SET, so that the selection of AMF or AMFSET may be performed according to the priority of AMF or AMF SET. For example, if the number of elements of the intersection of the slice combination index corresponding to the slice supported by the AMFb or the AMF SETb and the slice routing information is greater than the number of elements of the intersection of the slice combination index corresponding to the slice supported by the AMFa or the AMF SETa and the slice routing information, it may be determined that the priority of the AMFb or the AMF SETb is higher than the priority of the AMFa or the AMF SETa, and the access network side device may preferentially select the AMFb or the AMF SETb to serve the traffic of the user terminal.

Case three: the slice routing information contains core network function routing indices.

For example, the slice routing information includes a SET of core network function routing indexes (2,3), the core network function routing index corresponding to AMFa or AMF SETa is 2, the core network function routing index corresponding to AMFb or AMF SETb is 3, and the access network side device preferentially selects the core network function routing index corresponding to AMF or AMF SET to belong to AMF or AMF SET in the slice routing information without the influence of other parameters (such as an AMF identifier sent by the UE). For example, if the core network function routing index corresponding to AMFa or AMF SETa belongs to the slice routing information, and the core network function routing index corresponding to AMFb or AMF SETb also belongs to the slice routing information, then AMFa or AMF SETa and AMFb or AMF SETb have the same priority, in this case, the access network side device may select a more appropriate AMF or AMF SET to serve the service of the user according to other parameters, such as the AMF identifier sent by the UE.

Case four: the slice routing information contains various types of information.

For example, if the slice routing information includes a core network function routing index and a slice index, the determination may be made based on a plurality of types of information.

For another example, if the core network function routing index SET is (1,2) and the slice index SET is (3,5), the AMF or AMF SET supporting the slice index of 3 or the slice index of 5 is searched for in the AMF or AMF SET indicated by the core network function routing index.
