[0002] Different network slices can meet the service needs of user devices in different scenarios. In existing technologies, when allocating network slices to user devices, it is usually necessary to obtain the network slice feature values ​​from the user's subscription information. Then, a bilinear pairing algorithm can be used to match the network slice feature values ​​in the user's subscription information with the network slice feature values ​​of each of the multiple network slices stored in the core network, obtaining multiple matching degrees, and using the network slice with the highest matching degree to provide services to the user.

[0003] However, the above method involves a large amount of computation and cannot quickly determine the network slice that provides services to the user. Summary of the Invention

[0010] In a second aspect, a network slice determination apparatus is provided, comprising: a receiving unit, a processing unit, and a determining unit; the receiving unit is configured to receive a first network slice type set and a first random number sent by a user equipment; the first network slice type set is encrypted using a preset encryption algorithm and the first random number, and the first network slice type set includes at least one network slice type that is allowed one-to-one with at least one NSSAI of the user equipment; the processing unit is configured to encrypt the pre-configured network slice type set according to the preset encryption algorithm and the first random number to obtain a second network slice type set; the determining unit is configured to determine the target network slice to be allocated to the user equipment based on the intersection of the first network slice type set and the second network slice type set.

[0012] In one possible implementation, the determining unit is specifically used to: determine the number of identical slice features among the allowed network slice features corresponding to each network slice type and the number of pre-configured network slice features corresponding to each network slice type, thereby obtaining the number of matching features for each network slice type among multiple network slice types; and determine the network slice corresponding to the network slice type among multiple network slice types whose number of matching features is greater than a preset number as the target network slice.

[0018] The technical solution of the first aspect provided by this application brings at least the following beneficial effects: Existing technologies use bilinear pairing algorithms to determine matching values, which involves a large amount of computation, resulting in the inability to quickly determine network slices. This application receives a first set of network slice types and a first random number sent by a user equipment. The first set of network slice types is encrypted using a preset encryption algorithm and the first random number, and includes at least one network slice type that corresponds one-to-one with at least one allowed NSSAI of the user equipment. Then, according to the preset encryption algorithm and the first random number, the pre-configured set of network slice types is encrypted to obtain a second set of network slice types. Further, the target network slice allocated to the user equipment is determined based on the intersection of the first and second set of network slice types. This avoids the situation in existing technologies where bilinear pairing algorithms are used to determine matching values, and allows for rapid determination of the target network slice.

[0031] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0032] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0033] Before providing a detailed introduction to the network slice determination method provided in this application, let's briefly introduce the technical background involved in this application.

[0034] The papers "Efficient and secure service-oriented authentication supporting network slicing for 5G-enabled IoT" and "Flexible and anonymous network slicing selection for C-RAN enabled 5G service authentication" both rely on bilinear pairing and exponential operations for network slicing selection. However, bilinear pairing and exponential operations are time-consuming, increasing communication latency and making them unsuitable for scenarios with high latency requirements, such as virtual reality interaction scenarios.

[0035] Before providing a detailed introduction to the network slice determination method provided in this application, a brief introduction to the implementation environment (implementation architecture) involved in this application will be given first.

[0036] The network slice determination method provided in this application embodiment can determine the core network devices in the system by network slice determination. Figure 1 A schematic diagram of one structure of this network slice determination system is shown. Figure 1 As shown, the network slicing determination system 10 includes user equipment 11, server 12, core network equipment 13, and authentication server function (AUSF) 14. Among them, the core network equipment 13 includes access and mobility management function (AMF) 131, session management function (SMF) 132, and edge nodes 133.

[0037] Figure 2 This is a flowchart of a network slice determination method provided in an embodiment of this application. Figure 2 As shown, user equipment 11 is used to send a registration message to AMF131 and receive the subscribed NSSAI sent by AMF131 during the network slice initialization phase. The registration message includes a user identifier.

[0038] like Figure 2 As shown, user equipment 11 is also used to send a commit message to AMF131 during the service authorization phase. The commit message includes the subscribed NSSAI.

[0039] like Figure 2 As shown, AMF131 is used to receive the submission message sent by user equipment 11 and forward the submission message to SMF132.

[0040] like Figure 2 As shown, SMF132, in response to the received submission information, queries AUSF14 for the initial allowed NSSAI corresponding to user equipment 11. Then, based on a preset encryption algorithm and a second random number, it encrypts the network slice types in the initial allowed NSSAI to obtain a set of allowed network slice types, and encrypts the network slice features corresponding to the network slice types in the initial allowed NSSAI. The set of allowed network slice types and the encrypted network slice features corresponding to the network slice types in the initial allowed NSSAI are then sent to server 12.

[0041] like Figure 2 As shown, server 12 is used to receive the set of allowed network slice types and the encrypted network slice features corresponding to the network slice types in the initial allowed NSSAI, and send the set of allowed network slice types and the encrypted network slice features corresponding to the network slice types in the initial allowed NSSAI to user equipment 11.

[0042] like Figure 2 As shown, AMF131 is used to obtain multiple initially pre-configured network slice types, and encrypt the multiple initially pre-configured network slice types according to a preset encryption algorithm and a second random number to obtain a set of pre-configured network slice types, and send the set of pre-configured network slice types to edge node 133.

[0043] like Figure 2 As shown, user equipment 11 is also used to encrypt the set of allowed network slice types using a preset encryption algorithm and a first random number during the service access phase, to obtain a first network slice type set, and to send the first network slice type set and the first random number to the edge node 133.

[0044] like Figure 2 As shown, edge node 133 is used to receive a first set of network slice types and a first random number during the network slice selection phase, and encrypt the pre-configured set of network slice types according to a preset encryption algorithm and the first random number to obtain a second set of network slice types. Then, based on the intersection of the first set of network slice types and the second set of network slice types, the target network slice allocated to the user equipment is determined.

[0045] For ease of understanding, the network slice determination method provided in this application will be described in detail below with reference to the accompanying drawings.

[0046] Figure 3 This is a flowchart illustrating yet another method for determining network slices according to an exemplary embodiment. For example... Figure 3 As shown, the network slice determination method includes the following steps:

[0047] S201, The core network equipment receives the first set of network slice types and the first random number sent by the user equipment.

[0048] The first network slice type set is encrypted using a preset encryption algorithm and a first random number, and the first network slice type set includes at least one network slice type that is allowed by the user equipment and corresponds one-to-one with at least one NSSAI.

[0049] As one possible implementation, the user equipment (UE) determines a first random number based on a preset space. Then, the UE encrypts the set of allowed network slice types using a preset encryption algorithm and the first random number, obtaining a first set of network slice types. It also encrypts the network slice feature corresponding to each allowed network slice type in the set of allowed network slice types, obtaining a first network slice feature corresponding to each first network slice type. Further, the UE sends the first set of network slice types, the first random number, and the first network slice feature corresponding to each first network slice type to the core network equipment.

[0050] For example, the preset space can be Where Z is the size of the preset space, and p is a prime number that is not equal to 1.

[0051] For example, the first set of network slice types can be (N1, N2, ..., N...). s ) represents the number of allowed network slice types, and s represents the number of allowed network slice types. The first network slice feature corresponding to the j-th first network slice type can be represented by C. j It means that C j =(C j1 C j2 C jm), where m represents the number of network slice features corresponding to the j-th allowed network slice type.

[0052] S202. The core network equipment encrypts the pre-configured set of network slice types according to the preset encryption algorithm and the first random number to obtain the second set of network slice types.

[0053] As one possible implementation, the core network device encrypts a pre-configured set of network slice types using a preset encryption algorithm and a first random number to obtain a second set of network slice types. Further, the core network device encrypts the network slice features corresponding to each second network slice type using the preset encryption algorithm and the first random number to obtain the second network slice features corresponding to each second network slice type.

[0054] For example, the second set of network slice types can be (DS1, DS2, ..., DS...). n () represents the number of pre-configured network slice types, where n represents the number of pre-configured network slice types. The second network slice feature corresponding to the j-th second network slice type can be represented by D. j D indicates j =(D j1 D j2 ,…,D jm ), where m represents the number of second network slice features corresponding to the j-th second network slice type.

[0055] S203. The core network equipment determines the target network slice to be allocated to the user equipment based on the intersection of the first network slice type set and the second network slice type set.

[0056] As one possible implementation, the core network device determines the intersection of the first network slice type set and the second network slice type set, and determines the target network slice based on the number of network slice types in the intersection of the first network slice type set and the second network slice type set.

[0057] Understandably, existing technologies use bilinear pairing algorithms to determine matching values, which involves a large amount of computation, making it difficult to quickly determine network slices. This application receives a first set of network slice types and a first random number sent by a user equipment. The first set of network slice types is encrypted using a preset encryption algorithm and the first random number, and includes at least one network slice type that corresponds one-to-one with at least one allowed NSSAI of the user equipment. Then, a pre-configured set of network slice types is encrypted using the preset encryption algorithm and the first random number to obtain a second set of network slice types. Further, the target network slice allocated to the user equipment is determined based on the intersection of the first and second set of network slice types. This avoids the need for bilinear pairing algorithms in existing technologies to determine matching values, enabling rapid determination of the target network slice.

[0058] In some embodiments, in order to efficiently determine the target network slice, such as Figure 4 As shown, the above S203 can be implemented in the following way:

[0059] S301. If there is no network slice type in the intersection of the first network slice type set and the second network slice type set, the core network device determines the preset network slice as the target network slice.

[0060] S302. If the core network device includes a network slice type in the intersection of the first network slice type set and the second network slice type set, it determines the network slice corresponding to the network slice type included in the intersection of the first network slice type set and the second network slice type set as the target network slice.

[0061] S303. When the core network device includes multiple network slice types in the intersection of the first network slice type set and the second network slice type set, it obtains the allowed network slice features corresponding to each network slice type and the pre-configured network slice features corresponding to each network slice type.

[0062] For example, taking a case where the intersection of the first network slice type set and the second network slice type set includes multiple network slice types A1 and A2, the core network device obtains the allowed network slice feature corresponding to A1, i.e., the first network slice feature B1, and the pre-configured network slice feature corresponding to A1, i.e., the second network slice feature C1. The core network device obtains the allowed network slice feature corresponding to A, i.e., the first network slice feature B2, and the pre-configured network slice feature corresponding to A2, i.e., the second network slice feature C2.

[0063] S304. The core network equipment determines the target network slice based on the allowed network slice characteristics corresponding to each network slice type and the pre-configured network slice characteristics corresponding to each network slice type.

[0064] As one possible implementation, the core network device determines the number of matching features for each network slice type based on the allowed network slice features and the pre-configured network slice features corresponding to each network slice type. Then, the core network device determines the target network slice based on the number of matching features for each network slice type.

[0065] The specific implementation method of this step can be referred to in the subsequent description of the embodiments of this application, and will not be repeated here.

[0066] Understandably, the target network slice can be quickly determined based on the number of network slice types in the intersection of the first set of network slice types and the second set of network slice types.

[0067] In some embodiments, in order to accurately determine the target network slice, such as Figure 5 As shown, the above S304 can be implemented in the following manner:

[0068] S401. The core network device determines the number of matching features for each network slice type by taking the allowed network slice features corresponding to each network slice type and the number of identical slice features among the pre-configured network slice features corresponding to each network slice type, thereby obtaining the number of matching features for each network slice type among multiple network slice types.

[0069] For example, the intersection of the first set of network slice types and the second set of network slice types includes multiple network slice types A1 and A2, and the allowed network slice feature corresponding to A1 is the first network slice feature B1 = (B 11 B 12 B 13 B 14 B 15 B 16 The pre-configured network slice feature corresponding to A1 is the second network slice feature C1 = (B 11 B 12 B 13 B 14 B 15 The allowed network slice feature corresponding to A2 is the first network slice feature B2 = (B 21 B 22 B 23 B 24 B 25 The pre-configured network slice feature corresponding to A2 is the second network slice feature C2 = (B21 B 22 For example, the core network equipment determines that the number of matching features for A1 is 5 and the number of matching features for A2 is 2.

[0070] S402. The core network device identifies the network slice corresponding to the network slice type with a number of matching features greater than a preset number among multiple network slice types as the target network slice.

[0071] For example, with a preset quantity of 2, the core network device will determine the network slice corresponding to A1 as the target network slice.

[0072] It is understandable that by accurately determining the number of matching features for each network slice type among multiple network slice types, the network slice corresponding to the network slice type with a number of matching features greater than a preset number can be identified as the target network slice, thereby accurately determining the target network slice and meeting user needs.

[0073] In some embodiments, in order to determine a pre-configured set of network slice types, such as Figure 6 As shown, the network slice determination method provided in this application embodiment further includes:

[0074] S501, the core network equipment obtains multiple initially pre-configured network slice types.

[0075] As one possible implementation, the core network device obtains multiple initially pre-configured network slice types and the network slice characteristics corresponding to each initially pre-configured network slice type.

[0076] For example, the i-th initially pre-configured network slice type can be represented by the symbol SST. i The feature of the nth network slice corresponding to the i-th initially pre-configured network slice type can be represented by the symbol S. i AI n express.

[0077] S502, the core network equipment encrypts multiple initially pre-configured network slice types according to a preset encryption algorithm and a second random number, to obtain a set of pre-configured network slice types.

[0078] As one possible implementation, the core network device determines a second random number based on a preset space. Then, the core network device encrypts multiple initially pre-configured network slice types using a preset encryption algorithm and the second random number, obtaining a pre-configured set of network slice types. Further, the core network device encrypts the network slice features corresponding to each initially pre-configured network slice type using the preset encryption algorithm and the second random number, obtaining a third network slice feature corresponding to each pre-configured network slice type.

[0079] For example, a pre-configured set of network slice types can be used as (S1, S2, ..., S...). n ) indicates that, among which, S i =H k (SST i ), H k This indicates encryption based on a preset encryption algorithm H and a second random number k, where n represents the number of pre-defined network slice types. The third network slice feature corresponding to the i-th pre-configured network slice type can be represented by F. i It means that F i =(F i1 ,F i2 ,…,F it ), where t represents the number of third network slice features corresponding to the i-th pre-configured network slice type.

[0080] Understandably, encrypting multiple initially pre-configured network slice types using a preset encryption algorithm and a second random number can improve data security and effectively protect data from leakage.

[0081] In some embodiments, in order to determine the set of allowed network slice types, such as Figure 7 As shown, the network slice determination method provided in this application embodiment further includes:

[0082] S601, the core network equipment obtains at least one initial permission NSSAI.

[0083] One initial NSSAI corresponds to one network slice type.

[0084] As one possible implementation, the core network equipment receives a subscription message sent by the user equipment and determines at least one initial permission NSSAI based on the subscription information.

[0085] S602. The core network equipment encrypts the network slice types in the initially allowed NSSAI according to the preset encryption algorithm and the second random number to obtain the set of allowed network slice types.

[0086] As one possible implementation, the core network device encrypts the network slice types in the initially allowed NSSAI according to a preset encryption algorithm and a second random number, obtaining a set of allowed network slice types. Then, the core network device encrypts the network slice features corresponding to the network slice types in the initially allowed NSSAI according to the preset encryption algorithm and the second random number, obtaining a fourth network slice feature corresponding to the allowed network slice type.

[0087] For example, the set of allowed network slice types can be (US1, US2, ..., US...).s ) represents the number of allowed network slice types, and s represents the number of allowed network slice types. The fourth network slice feature corresponding to the j-th allowed network slice type can be represented by UF. j It means that F j =(UF j1 UF j2 ,…,UF jm ), where m represents the number of fourth network slice features corresponding to the j-th allowed network slice type.

[0088] S603, The core network equipment sends the set of allowed network slice types to the user equipment.

[0089] Understandably, encrypting at least one initial NSSAI using a preset encryption algorithm and a second random number can improve data security and effectively protect data from being leaked.

Figure 8 As shown, the network slice determination device 700 includes a receiving unit 701, a processing unit 702, a determination unit 703, an acquisition unit 704, and a sending unit 705.

[0093] The receiving unit 701 is used to receive a first network slice type set and a first random number sent by the user equipment; the first network slice type set is encrypted by a preset encryption algorithm and the first random number, and the first network slice type set includes at least one network slice type that is allowed by the user equipment and corresponds one-to-one with at least one NSSAI.

[0094] The processing unit 702 is used to encrypt a pre-configured set of network slice types according to a preset encryption algorithm and a first random number to obtain a second set of network slice types.

[0095] The determining unit 703 is used to determine the target network slice to be allocated to the user equipment based on the intersection of the first network slice type set and the second network slice type set.

[0096] Optionally, to efficiently determine the target network slice, such as Figure 8 As shown, the aforementioned determining unit 703 is specifically used for:

[0097] If no network slice type exists in the intersection of the first set of network slice types and the second set of network slice types, the preset network slice is determined as the target network slice.

[0098] If the intersection of the first set of network slice types and the second set of network slice types includes a network slice type, the network slice corresponding to the network slice type included in the intersection of the first set of network slice types and the second set of network slice types is determined as the target network slice.

[0099] When the intersection of the first set of network slice types and the second set of network slice types includes multiple network slice types, obtain the allowed network slice features corresponding to each network slice type and the pre-configured network slice features corresponding to each network slice type.

[0100] The target network slice is determined based on the allowed network slice features corresponding to each network slice type and the pre-configured network slice features corresponding to each network slice type.

[0101] Optionally, to accurately determine the target network slice, such as Figure 8 As shown, the aforementioned determining unit 703 is specifically used for:

[0102] The number of identical slice features among the allowed network slice features corresponding to each network slice type and the number of pre-configured network slice features corresponding to each network slice type are used to determine the number of matching features for each network slice type, thus obtaining the number of matching features for each network slice type in multiple network slice types.

[0103] The network slice corresponding to the network slice type with more than a preset number of matching features among multiple network slice types is determined as the target network slice.

[0104] Optionally, to determine the pre-configured set of network slice types, such as Figure 8 As shown, the acquisition unit 704 is used to acquire multiple initially pre-configured network slice types;
