Introduction to slicing or network slicing:

At present, in order to identify end-to-end network slices, each network slice can be uniquely identified by a single network slice Selection Assistance Information (S-NSSAI), and each S-NSSAI can include a slice/service type ( Slice/Serive Type, SST) and Slice Differentiator (SD).

Network slicing always consists of a radio access network (Radio Access Network, RAN) part and a core network (Core Network, CN) part. The support of network slicing relies on the following principle: the traffic of different slices is processed by different Protocol Data Unit (PDU) sessions. The network side can implement different network slices by scheduling and providing different L1/L2 configurations.

In the fifteenth version (Release 15, R15) of the New Radio (NR), the User Equipment (UE) does not know whether the RAN supports a certain network slice when trying to access the RAN. The UE may carry one or more requested NSSAIs (ie, requested NSSAI) in a radio resource control (Radio Resource Control, RRC) connection establishment complete message, including the S-NSSAI of the network slice that the UE wants to register.

The RAN selects the appropriate access and mobility management function (Access and Mobility Management Function, AMF) based on the requested NSSAI provided by the UE. If the RAN cannot make a choice, for example, the UE does not provide requested NSSAI or the UE provides requested NSSAI but the RAN cannot find it. To the AMF that matches its capabilities, you can choose the default AMF. The AMF determines which requested S-NSSAI can be allowed based on the requested NSSAI provided by the UE, the UE's slice subscription information (for example, subscribed NSSAI) and the RAN side slice configuration.

Referring to Figure 1, Figure 1 is a structural diagram of a network system applicable to an embodiment of this application. As shown in Figure 1, it includes a terminal device 11, an access network side device 12, and a core network side device 13, wherein the terminal device 11 It can be a mobile phone, a tablet (Personal Computer), a laptop (Laptop Computer), a personal digital assistant (Personal Digital Assistant, PDA), a mobile Internet device (Mobile Internet Device, MID) or a wearable device (Wearable Device) and other user-side devices. It should be noted that the 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. The access network side device may be a base station, such as a macro station, LTE eNB, 1G NR NB, gNB, etc. It can also be a small station, such as a low power node (Low Power Node, LPN) pico, femto, etc., or an access point (Access Point, AP). Among them, the base station may also be a network node composed of a central unit (Central Unit, CU) and multiple TRPs managed and controlled by it. 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 embodiments of the present application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios thereof.

The embodiment of the present application provides an information processing method, which is applied to the non-access stratum (NAS) of a terminal device. Refer to FIG. 2, which is a flowchart of an information processing method provided by an embodiment of the present application. As shown in FIG. 2, it includes the following steps:

Step 201: The non-access layer of the terminal device transmits slice usage information to the access layer of the terminal device; wherein the slice usage information is generated according to slice auxiliary information, and the slice auxiliary information is used to assist the non-access layer Layer selection slice.

In this embodiment, the above-mentioned slice auxiliary information may be used to indicate part or all of the slices supported by the network side (that is, slices), or may be used to indicate part or all of the slices that the network side allows the terminal device to access. Assist the non-access layer to perform slice selection. For example, if the slices supported by the network side are slice a, slice b, slice c, and slice d, the above slice auxiliary information can be used to indicate slice a, slice b, slice c, and slice d, or the network side allows terminal devices to access The slices are slice b, slice c, and slice d, and the slice auxiliary information can be used to indicate slice b, slice c, and slice d. It should be noted that the aforementioned slice auxiliary information may be pre-configured or configured by the core network side device.

The slice usage information described above may be used to indicate the slice selected by the non-access stratum. Specifically, the non-access stratum may perform slice selection based on the slice indicated by the slice assistance information, that is, the non-access stratum may generate slices based on the slice assistance information. The above slice usage information. For example, the slice auxiliary information may be used to indicate slice b, slice c, and slice d. If slice b is selected by the non-access layer, the slice usage information may be used to indicate slice b.

In the above step 201, the non-access layer of the terminal device transmits slice usage information to the access layer of the terminal device, so that the access layer of the terminal device can perform cell selection or report slice routing information based on the slice usage information. Since the terminal device can learn the slices supported by the network side based on the slice auxiliary information, generating slice usage information based on the slice auxiliary information can improve the accuracy of the slice selected by the terminal device, thereby improving the reliability of slice access.

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

Correspondence between slices and slice indexes, or a list of slice indexes;

Correspondence between slice and slice composite index, or slice composite index list;

Correspondence between slices and cell identities, or a list of cell identities;

Correspondence between slices and tracking area identifiers, or a list of tracking area identifiers;

Correspondence between slice and core network function routing index, or core network function routing index list;

Correspondence between slices and frequency points, or frequency point list;

Correspondence between slices and frequency bands, or frequency band list.

In this embodiment, the aforementioned slice auxiliary information may include information corresponding to one or more slices. For ease of understanding, this embodiment will be described with an example as follows:

For the correspondence between the slice and the slice index (ie Slice to Slice Index) or the slice index list. For example, the slices supported by the network side are slice_a, slice_b, slice_c, slice_d, and slice_e, and the corresponding slice indexes (that is, slice indexes) are 1, 2, 3, 4, and 5, respectively. If the UE is allowed to access slice_b, slice_c, slice_d , The corresponding relationship between the slice and the slice index sent by the network side to the UE can be {<slice_b,2>,<slice_c,3>,<slice_d,4>}, or the slice index list sent by the network side to the UE can be { 2,3,4}. It should be noted that different slices can correspond to the same slice index, and the same slice can also correspond to different slice indexes.

Optionally, the network side may also generate a slice index that does not correspond to any slice, and the correspondence between the above-mentioned slice and the slice index may also include a slice index that does not correspond to any slice, so as to improve the security of slice access. For example, the slice indexes 7, 8, and 9 do not correspond to any slices. At this time, the corresponding relationship between the slice and the slice index sent by the network side to the UE can be {<slice_b,(2,7)>,<slice_c,(3, 9)>,<slice_d,(4,7,9)>}, or the slice index list sent by the network to the UE can be {(2,7),(3,9),(4,7,9)} .

For the correspondence between the slice and the slice combination index (that is, the Slice to Slice Combination Index), or the slice combination index list. For example, the network side 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 corresponding relationship between the slice and the slice combination index sent by the network to the UE can be {<slice_a,(1,2)>,<slice_b,(1,3)>}, or the network The slice combination index list sent by the network side to the UE can be {(1,2),(1,3)}; if the UE is allowed to access slice_a, slice_b, and slice_d, the slice and slice combination index list sent to the UE by the network side The corresponding relationship can 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 can be {(1 ,2),(1,3),(3)}.

For the correspondence between the slice and the cell ID (ie cell id) or the cell ID list. For example, cell id1 (that is, the cell with the cell ID of 1) supports the access of slice_a and slice_b, cell id2 supports the access of slice_a and slice_c, and cell id3 supports the access of slice_b, slice_c, and slice_d. If the UE is allowed to access Enter slice_a and slice_b, the corresponding relationship between the slice and cell ID sent by the network side to the UE can be {<slice_a,(cell id1,cell id2)>,<slice_b,(cell id1,cellid3)>}, or sent by the network side The cell ID list for the UE can be {(cell id1,cell id2),(cell id1,cell id3)}; if the UE is allowed to access slice_a, slice_b, and slice_d, the network side sends the corresponding slice to the UE and the cell ID The relationship can be {<slice_a,(cell id1,cell id2)>,<slice_b,(cell id1,cell id3)>,<slice_d,(cell id3)>}, or the cell identification list sent by the network side to the UE can be {(cell id1,cell id2),(cell id1,cell id3),(cell id3)}.

For the correspondence between the slice and the tracking area (Tracking Area, TA) identifier or the tracking area identifier list. For example, TA1 supports the access of slice_a and slice_b, TA2 supports the access of slice_a and slice_c, and TA3 supports the access of slice_b, slice_c, and slice_d. If the UE is allowed to access slice_a and slice_b, the network side sends the slice sum to the UE. The corresponding relationship of the tracking area identification can be {<slice_a,(TA1,TA2)>,<slice_b,(TA1,TA3)>}, or the tracking area identification list sent by the network side to the UE can be {(TA1,TA2), (TA1,TA3)}. If the UE allows access to slice_a, slice_b, and slice_d, the corresponding relationship between the slice and the tracking area identifier sent by the network side to the UE is {<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 between the slice and the core network function routing identifier (that is, slice to slice routing index), or the core network function routing index list. For example, the network side configuration <AMFm,...,AMFn> or <AMF SETm,...,AMF SETn> or <AMF SETa,...,AMF SETb, AMFm,...,AMFn,...> is a slice routing group, corresponding to the core network The functional routing index (that is, 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 corresponding relationship between the slice sent to the UE by the network side and the core network function routing index can be {<slice_a,(1,2)>,<slice_b,(4)>}, or the network The core network function routing index list sent by the side to the UE can be {(1,2),(4)}, where the slice routing index with a value of 1 and the slice routing group corresponding to the slice routing index with a value of 2 both include AMFk or AMF SETk, where AMFk or AMF SETk supports the service slice_a. Similarly, the meaning of the relationship between slice_b and slice routing index=4 can be known.

For the correspondence between slices and frequency points (ie Slice to Frequency Number) or the above frequency point list, for example, the slices supported by the network side are slice_a, slice_b, and the corresponding frequency points (ie frequency numbers) are (FN1, FN2, FN3). ), (FN4, FN5), if the UE is allowed to access slice_a, slice_b, the corresponding relationship between the slice and frequency point sent to the UE by the network side is {<slice_a,(FN1,FN2,FN3)>,<slice_b,( FN4,FN5)>}, or the frequency list sent by the network side to the UE may be {(FN1,FN2,FN3),(FN4,FN5)}. It should be noted that different slices can correspond to the same set of frequency points.

For the correspondence between slices and frequency bands (that is, slice to frequency band) or a list of frequency bands. For example, the slices supported by the network side are slice_a, slice_b, and slice_c, and the corresponding frequency bands (ie frequency bands) are (FB1, FB2), FB3, (FB1, FB4, FB5) respectively. If the UE is allowed to access slice_b, slice_c, Then the corresponding relationship between the slice and 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,FB4,FB5)}. It should be noted that different slices can correspond to the same frequency band set.

The aforementioned slice auxiliary information is configured according to the granularity of the registration area, that is, each registration area corresponds to a set of slice auxiliary information.

For example, in PLMN 1, the corresponding relationship between slice and slice index can be {<slice_a,1>,<slice_b,2>,<slice_c,3>,<slice_d,4>,<slice_f,5>}, under PLMN2 The corresponding relationship between slice and slice index can be {<slice_f,2>,<slice_g,3>,<slice_h,4>,<slice_i,5>}.

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

Slice combination index;

Cell ID;

Tracking area identification;

Core network function routing index;

Since the cell assistance information can be broadcast in segments through the air interface, multiple types of information included in the cell assistance information can be cascaded and combined. For example, first determine whether the frequency meets the condition, and then determine whether the core network function routing index in SIB1 meets the condition. , And then judge whether the frequency bands in other SIBs meet the conditions, so as to obtain the cell selection priority; multiple types of information included in the cell assistance information can also be combined, for example, the cell identification and core network function routing index are all sent through SIB1, Therefore, it can be judged whether the cell identification and the core network function routing index satisfy the conditions at the same time, and thus the cell selection priority can be obtained.

The number of elements in the intersection of the index sets the priority of cell selection.

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

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

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 examples are used to describe the selection of AMF or AMF SET by the access network side device based on slice routing information:

Case 1: The slice routing information includes a slice index.

For example, the slice index set included in the slice routing information is (2, 3, 7), the slice index set corresponding to the slice supported by AMFa or AMF SETa is (1, 3), and the slice index set corresponding to the slice supported by AMFb or AMF SETb It is (1,2,3). Without the influence of other parameters (such as the AMF identifier sent by the UE), the access network side device can base on the intersection of the slice index corresponding to the slice supported by the AMF or AMF SET and the slice routing information Set the priority of AMF or AMF SET with the number of elements, so that AMF or AMF SET can be selected according to the priority of AMF or AMF SET. For example, if the number of elements in the intersection of the slice index corresponding to the slice supported by AMFb or AMF SETb and the slice routing information is greater than the number of elements in the intersection of the slice index and the slice routing information corresponding to the slice supported by AMFa or AMF SETb, it can be determined The priority of AMFb or AMF SETb is higher than the priority of AMFa or AMF SETa, and the access network side device can preferentially select AMFb or AMF SETb to serve the service 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 before performing the above steps.

It should be noted that if the slice routing information includes only one slice index, or only one slice index is included after removing the slice index that does not correspond to any slice, the access network side device can determine that it supports the AMF or AMF of the slice corresponding to the slice index. SET, and select one of the services to serve the user terminal.

Case 2: The slice routing information includes a slice combination index.

For example, the slice combination index set included in the slice routing information is (2, 3), the slice combination index set corresponding to the slice supported by AMFa or AMF SETa is (1, 3), and the slice combination index corresponding to the slice supported by AMFb or AMF SETb The set is (1,2,3). Without the influence of other parameters (such as the AMF identifier sent by the UE), the access network side device can base on the slice combination index and slice routing information corresponding to the slices supported by AMF or AMF SET The number of elements in the intersection sets the priority of AMF or AMF SET, so that AMF or AMF SET can be selected according to the priority of AMF or AMF SET. For example, if the number of elements in the intersection of the slice combination index and the slice routing information corresponding to the slice supported by AMFb or AMF SETb is greater than the number of elements in the intersection of the slice combination index and the slice routing information corresponding to the slice supported by AMFa or AMF SETb, then It can be determined that the priority of AMFb or AMF SETb is higher than that of AMFa or AMF SETa, and the access network side device can preferentially select AMFb or AMF SETb to serve the service of the user terminal.

Case 3: The slice routing information includes the core network function routing index.

For example, the core network function routing index set included in the slice routing information is (2, 3), the core network function routing index corresponding to AMFa or AMF SETa is 2, and the core network function routing index corresponding to AMFb or AMF SETb is 3. Under the influence of other parameters (such as the AMF identifier sent by the UE), the access network side device preferentially selects the core network function routing index corresponding to the AMF or AMF SET to belong to the AMF or AMF SET in the slice routing information. For example, if the core network function routing index corresponding to AMFa or AMF SETa belongs to slice routing information, and the core network function routing index corresponding to AMFb or AMF SETb also belongs to 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 can select a more appropriate AMF or AMF SET to serve the user's business based on other parameters, such as the AMF identifier sent by the UE.

Case 4: The slice routing information contains multiple types of information.

For example, if the slice routing information includes the core network function routing index and the slice index, it can be judged based on multiple 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 indicated by the core network function routing index is searched for a slice index of 3 or a slice index of 5 AMF or AMF SET.
