The slice parameter configuration method provided by the embodiment of the invention can be applied to terminal equipment and a gNB (NextGeneration Node-B, 5G base station).
As shown in fig. 1, an embodiment of the present invention provides a slice parameter configuration method, which is applied to a terminal device, and the method may include the following steps:
s11, sending a Slice registration request to NSSF (Network Slice Selection Function).
After the terminal device is switched from another gNB to the current gNB, the terminal device may initiate a slice registration request to the core network, and specifically, the terminal device may send the slice registration request to a core network element NSSF.
And S12, in response to receiving the confirmation registration message sent by the NSSF, acquiring the first slice identifier carried in the confirmation registration message.
The NSSF receives the slice registration request sent by the terminal equipment and feeds back a registration confirmation message carrying the first slice identifier to the terminal equipment. The first Slice identifier is an identifier of a Slice allowing the terminal device to register, that is, an Allowed NSSAI (Network Slice Selection Assistance Information). Subsequent terminal devices may be served by the first slice identified by the Allowed NSSAI.
S13, configuring subcarrier spacing and data frame length for the first slice at least according to the correspondence obtained in advance from the currently connected gbb of the terminal device and the first slice identifier.
The corresponding relationship is the corresponding relationship among the slice identifier, the subcarrier interval and the data frame length, and one slice identifier corresponds to at least two subcarrier intervals and at least one data frame length. The corresponding relationship may be obtained in advance by the terminal device from a gbb currently connected to the terminal device, and the gbb currently connected to the terminal device determines the corresponding relationship according to channel estimation information, phase noise information, and signal strength of a radio channel in a coverage area of the gbb.
It can be seen from the foregoing steps S11-S13 that, with the slice parameter configuration method provided in the embodiment of the present invention, after receiving the registration confirmation message carrying the first slice identifier and sent by the NSSF, the subcarrier interval and the data frame length are configured for the first slice at least according to the correspondence relationship and the first slice identifier that are obtained in advance from the gbb currently connected to the terminal device. The corresponding relation is determined by the gNB currently connected with the terminal device according to the channel estimation information, the phase noise information and the signal strength of the wireless channel of the gNB coverage area, and is the corresponding relation among the slice identification, the subcarrier interval and the data frame length, wherein one slice identification corresponds to at least two subcarrier intervals and at least one data frame length, so that the configuration of the subcarrier interval and the data frame length for a first slice is realized on the basis of the channel estimation information, the phase noise information and the signal strength of the wireless channel of the gNB coverage area currently connected with the terminal device and the first slice identification allocated to the terminal device by the NSSF, the communication requirement of the terminal device for the slice service can be met, and the energy consumption of the terminal device can be reduced as much as possible.
As shown in fig. 2, in some embodiments, the configuring, for the first slice, the subcarrier interval and the data frame length according to at least the correspondence relationship and the first slice identifier obtained in advance from the gNB currently connected to the terminal device (i.e., S13), may include the following steps:
s131, when the terminal device is not currently connected to a slice, determining at least two subcarrier intervals and at least one data frame length corresponding to the first slice identifier according to the correspondence relationship and the first slice identifier obtained in advance from the gNB currently connected to the terminal device.
Before establishing a slice session with a first slice, a terminal device may first determine the number of slices currently connected to the terminal device, and when the number of slices currently connected to the terminal device is 0, that is, the terminal device is not currently connected to a slice, the terminal device may directly configure a subcarrier interval and a data frame length for the first slice according to the correspondence and a first slice identifier.
Specifically, the terminal device may query, according to the first slice identifier, a correspondence relationship obtained by the gNB to which the terminal device is currently connected, where in the correspondence relationship, one slice identifier corresponds to at least two subcarrier intervals and at least one data frame length, and the terminal device may query to obtain at least two subcarrier intervals and at least one data frame length corresponding to the first slice identifier.
S132, determining a maximum value of at least two subcarrier intervals corresponding to the first slice identifier, and determining a minimum value of at least one data frame length corresponding to the first slice identifier.
After determining the at least two subcarrier intervals and the at least one data frame length corresponding to the first slice identifier, the terminal device may further determine a maximum value of the at least two subcarrier intervals corresponding to the first slice identifier and a minimum value of the at least one data frame length corresponding to the first slice identifier.
S133, configuring the subcarrier spacing of the first slice as a maximum value; the data frame length of the first slice is configured to be a minimum.
Under the condition of increasing the subcarrier interval and reducing the data frame length, the energy consumption of the terminal equipment is reduced, the at least two subcarrier intervals corresponding to the first slice identifier and the at least one data frame length in the corresponding relation are slice parameters applicable to the first slice, the terminal equipment configures the subcarrier interval of the first slice as the maximum value of the at least two subcarrier intervals corresponding to the first slice identifier, and configures the data frame length of the first slice as the minimum value of the at least one data frame length corresponding to the first slice identifier, so that the communication requirement of the terminal equipment on slice services can be met, and the energy consumption of the terminal equipment can be reduced as much as possible.
The above steps S131 to S133 will be briefly described with reference to table 1.
Referring to table 1, the corresponding relationship may be a chart as shown in table 1, in which the slice type, the subcarrier interval, and the data frame length respectively corresponding to each slice identifier are recorded, as can be seen, the table includes slice identifiers NSSAI ID 1, NSSAI ID 2, NSSAI ID 3, NSSAI ID 4, and the like, and each slice identifier corresponds to at least two subcarrier intervals andat least one data frame length, subcarrier spacing may be based on a parameter m1、m2、m3、m4Etc., and the data frame length may be represented by a CP (Cyclic Prefix) length in the data frame.
TABLE 1
Figure BDA0003084453250000101
It should be noted that "CP lengthening" and "normal" shown in table 1 are only used to explain that the data frame length corresponding to the slice identifier in the correspondence relationship may be a length value obtained by lengthening the normal CP and a length value of the normal CP, and it does not mean that the data frame length in the correspondence relationship is "CP lengthening" and "normal", and the correspondence relationship may not include the slice type.
Assuming that the first slice ID is NSSAI ID 1, querying the correspondence may result in: the subcarrier spacing corresponding to NSSAI ID 1 is
Figure BDA0003084453250000102
m1(0,1,2) comprising: 15*(20)kHz、15*(21) kHz and 15 x (2)2) kHz (i.e., 15kHz, 30kHz, and 60kHz), the data frame length for NSSAI ID 1 includes: "CP lengthening" and "Normal". The terminal device may further determine that a maximum value of at least two subcarrier intervals corresponding to the first slice identifier is 60kHz, and determine that a minimum value of at least one data frame length corresponding to the first slice identifier is a normal CP length value, then configure the subcarrier interval of the first slice to 60kHz, and configure the data frame length of the first slice to the normal CP length value.
As shown in fig. 3, in some embodiments, the configuring, for the first slice, the subcarrier spacing and the data frame length according to at least the correspondence relationship and the first slice identifier obtained in advance from the gNB currently connected to the terminal device (i.e., S13), may include the following steps:
s14, when the terminal device is currently connected to at least one second slice, configuring a subcarrier interval and a data frame length for the first slice according to each second slice identifier, the correspondence obtained in advance from the gNB currently connected to the terminal device, and the first slice identifier.
The second slice is a slice currently connected to the terminal device, and the first slice is a slice to be connected to the terminal device.
Before establishing a slice session with a first slice, a terminal device may first determine the number of slices currently connected to the terminal device, and when the number of slices currently connected to the terminal device is not 0, that is, the terminal device is currently connected to at least one second slice, the terminal device may directly configure a subcarrier interval and a data frame length for the first slice according to the correspondence and a first slice identifier.
As shown in fig. 4, in some embodiments, configuring the subcarrier spacing and the data frame length for the first slice according to each second slice identifier, the correspondence relationship obtained in advance from the currently connected gNB of the terminal device, and the first slice identifier (i.e., as described in S14), may include the following steps:
s141, determining at least two subcarrier intervals and at least one data frame length corresponding to the first slice identifier according to the correspondence obtained in advance from the currently connected gbb of the terminal device and the first slice identifier.
And S142, determining at least two subcarrier intervals and at least one data frame length corresponding to each second slice identifier according to each second slice identifier and the corresponding relation.
The terminal device may query the corresponding relationship according to each second slice identifier, so as to obtain at least two subcarrier intervals and at least one data frame length corresponding to each second slice identifier through querying.
It should be understood that the execution sequence of step S141 and step S142 is not limited.
S143, determining a maximum value in an intersection when at least two of the at least two subcarrier spacings corresponding to the first slice identifier and the at least two subcarrier spacings corresponding to the second slice identifiers have an intersection.
Here, "both" means "at least two subcarrier spacings corresponding to the first slice identification" and "at least two subcarrier spacings corresponding to any one of the second slice identifications", or "at least two subcarrier spacings corresponding to one second slice identification" and "at least two subcarrier spacings corresponding to another second slice identification".
Assuming that the number of the second slices (which may also be referred to as the second slice identifier) is M, the intersection between the at least two slices may include any of the following cases: the (M +1) ones have intersection, any M ones have intersection, and any (M-1) ones have intersection … ….
In at least two subcarrier intervals corresponding to the first slice identifier and at least two subcarrier intervals corresponding to each second slice identifier, in the case that there is an intersection between (M +1) persons, the terminal device may determine a maximum value in the intersection; in the case where there is no intersection between the (M +1) persons but there is an intersection between any M persons, the terminal device may determine the maximum value in the intersection between the M persons, and if there is an intersection between any M persons and there are a plurality of intersections, the terminal device may also determine the maximum value in each intersection, and then determine the maximum value … … in each maximum value, and so on, and details thereof are omitted.
Still referring to table 1 above, assuming that the first slice ID and each second slice ID include NSSAI ID 1, NSSAI ID 2, and NSSAI ID 3, it can be seen that there is no intersection between the subcarrier spacing corresponding to NSSAI ID 1, the subcarrier spacing corresponding to NSSAI ID 2, and the subcarrier spacing corresponding to NSSAI ID 3, but there is an intersection between the subcarrier spacing corresponding to NSSAI ID 1 and the subcarrier spacing corresponding to NSSAI ID 3 of 15 (2)2) kHz, and the intersection of the subcarrier spacing corresponding to NSSAI ID 2 and the subcarrier spacing corresponding to NSSAI ID 3 is 15 (2)3) kHz, at this time 15 x (2)2) kHz and 15 x (2)3) Maximum value in kHz is 15 x (2)3) kHz, the terminal device may configure the subcarrier spacing of the first slice to 15 x (2)3)kHz。
S144, configuring the subcarrier spacing of the first slice to be the maximum value.
S145, under the condition that at least two of the at least one data frame length corresponding to the first slice identifier and the at least one data frame length corresponding to each second slice identifier have an intersection, determining the minimum value in the intersection.
Wherein "both" means "at least one data frame length corresponding to a first slice identifier" at least one data frame length corresponding to any one second slice identifier ", or" at least one data frame length corresponding to one second slice identifier "at least one data frame length corresponding to another second slice identifier".
Assuming that the number of second slices (which may also be referred to as second slice identifiers) is N, there is an intersection between the at least two slices, which may include any of the following cases: there is intersection between (N +1) people, intersection between any N people, and intersection between any two of (N-1) people with intersection … ….
In at least one data frame length corresponding to the first slice identifier and at least one data frame length corresponding to each second slice identifier, the terminal device may determine a minimum value in an intersection set when there is an intersection set between (N +1) ones; in the case where there is no intersection between the (N +1) persons but there is an intersection between any N persons, the terminal device may determine the minimum value in the intersection between the N persons, and if there is an intersection between any N persons and there are a plurality of intersections, the terminal device may also determine the minimum value in each intersection, and then determine the minimum value … … in each minimum value, and so on, and details thereof are omitted.
Still referring to table 1 above, assuming that the first slice identifier and each second slice identifier include NSSAI ID 1, NSSAI ID 2, and NSSAI ID 3, it can be seen that, in the data frame length corresponding to NSSAI ID 1, the data frame length corresponding to NSSAI ID 2, and the data frame length corresponding to NSSAI ID 3, an intersection of the three is "normal", the terminal device may configure the data frame length of the first slice to be a normal CP length value.
And S146, configuring the length of the data frame of the first slice to be a minimum value.

m1(0,1,2), then the priority of the subcarrier spacing is: 15*(20)kHz>15*(21)kHz>15*(22) kHz (i.e. 15 kHz)>30kHz>60 kHz); the data frame length includes: "CP lengthened" and "normal", the priority of the data frame length is: CP lengthening>And (4) normal.
The terminal device may further select a subcarrier interval with the highest priority and a data frame length with the highest priority according to the sequence of the at least two subcarrier intervals and the sequence of the at least one data frame length corresponding to the first slice identifier in the correspondence.
S153, configuring the subcarrier spacing of the first slice to be a selected subcarrier spacing; the data frame length of the first slice is configured to be the selected one of the data frame lengths.
In some embodiments, when the terminal device is not in the energy saving mode or the terminal device does not receive the energy saving instruction and the terminal device is currently connected to at least one second slice, the terminal device may further determine the slice identifier with the highest priority according to the priority of the first slice identifier and each second slice identifier, and then determine at least two subcarrier intervals and at least one data frame length corresponding to the slice identifier with the highest priority according to the slice identifier with the highest priority and the corresponding relationship.

and S21, responding to the terminal device switching from other gNB to the current gNB, and sending a corresponding relation acquisition request to the gNB currently connected with the terminal device.
When the terminal device switches from other gnbs to the current gNB, the terminal device detects that the position of the terminal device is changed or the identifier ID of the currently connected gNB is changed, and then the terminal device may send a corresponding relationship acquisition request to the currently connected gNB of the terminal device.
And S22, receiving the corresponding relation sent by the gNB currently connected with the terminal equipment.
After receiving the corresponding relation acquisition request sent by the terminal equipment, the gNB currently connected with the terminal equipment determines the corresponding relation according to the channel estimation information, the phase noise information and the signal strength of the wireless channel of the gNB coverage area, and issues the corresponding relation to the terminal equipment.
As shown in fig. 8, an embodiment of the present invention provides a slice parameter configuration method, which is applied to a base station, and the method may include the following steps:
s31, in response to receiving the mapping relationship obtaining request sent by the terminal device connected to the local base station gNB, determining the mapping relationship according to the channel estimation information, the phase noise information, and the signal strength of the radio channel in the coverage area of the local gNB.
The corresponding relation is the corresponding relation among the slice identifier, the subcarrier interval and the data frame length, and one slice identifier corresponds to at least two subcarrier intervals and at least one data frame length.
The channel estimation information may include an average amplitude and a phase average variance of a signal in the wireless channel, and the gNB may estimate, by using a channel estimation algorithm, an influence of the wireless channel in a coverage area of the gNB on the input signal, so as to obtain an average amplitude and a phase average variance of the signal in the wireless channel. The phase noise information may include a phase noise mean.

For the same slice, the subcarrier spacing set in the case where the average amplitude is greater than the threshold 1 or the phase noise information is greater than the threshold 2 may be greater than the subcarrier spacing set in the case where the average amplitude is less than or equal to the threshold 1 and the phase noise information is less than or equal to the threshold 2; the CP length set in the case where the phase average variance is greater than the threshold value 3 or the signal strength is less than the threshold value 4 may be greater than the CP length set in the case where the phase average variance is less than or equal to the threshold value 3 and the signal strength is greater than or equal to the threshold value 4. The threshold 1, the threshold 2, the threshold 3 and the threshold 4 may be determined as the case may be.
