[0002] Network slicing is the process of dividing an operator's physical network into multiple virtual networks. Each virtual network is divided according to different service requirements, such as latency, bandwidth, security, and reliability, in order to flexibly respond to different network application scenarios.

[0003] In the relevant technologies, six types of network slices are divided, namely: enhanced mobile broadband, large-scale Internet of Things, ultra-high reliability and low latency communication, Internet of Vehicles, high-performance machine type communication, high data rate and low latency communication. However, at present, due to the increasing number of business scenarios for users, industries, families, etc., and each scenario has more extreme requirements for various aspects of network performance, these six types of network slices can no longer meet the current user needs for the network.

[0082] It is understandable that the various steps or operations in the embodiments of the present application are merely examples, and the embodiments of the present application may also perform other operations or variations of various operations. In addition, the various steps may be performed in different orders presented in the embodiments of the present application, and it is possible that not all operations in the embodiments of the present application need to be performed.

[0083] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0084] The technical solution provided in the embodiment of the present application can be applicable to a variety of systems, especially 6G systems. For example, the applicable system can be a global system of mobile communication (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) general packet radio service (GPRS) system, a long term evolution (LTE) system, a LTE frequency division duplex (FDD) system, a LTE time division duplex (TDD) system, an advanced long term evolution (LTE-A) system, a universal mobile telecommunication system (UMTS), a world-wide interoperability for microwave access (WiMAX) system, a 6G new radio (NR) system, etc. These various systems include terminals and network equipment. The system may also include a core network part, such as an evolved packet system (EPS), a 6G system (5GS), etc.

[0085] In order to understand the present invention more clearly, the problems existing in the prior art of the present invention are briefly described as follows:

[0086] 1. Existing network system architecture

[0087] Reference Figure 1 It is an existing network system architecture, including terminal UE, (radio) access network equipment (R)AN, network node (also a core network including multiple network element devices) and DN (Data Network).

[0088] Among them, the network element equipment in the core network includes: UPF (User Plane Function), AMF (Access and Mobility Management Function), SMF (Session management function), PCF (Policy Control Function), AF (Application Function), NSSF (Network slice selection function), AUSF (Authentication server function), UDM (Unified Data Management), NSACF (The Network Slice Admission Control Function), NSSAAF (Network Slice-Specific Authentication and Authorization Function). In addition, in Figure 1 Among them, N1 to N15, as well as N22, N58, N59, N80, N81, and Uu are all corresponding communication interfaces.

[0089] Based on Figure 1 In the existing network architecture, all communications between UE and other network element devices in the core network except (AMF, UPF and DF) must go through AMF, resulting in low communication efficiency.

[0090] 2. 6G Distributed Network Architecture

[0091] Reference Figure 2 The important trend of 6G network development is centralized and distributed network architecture. The original design of 5G and previous generations of network architecture is centralized control. With the development of the network, facing the dual driving forces of business development and technological development, the design of 6G network needs to consider the distributed architecture, and its control gradually evolves towards distributed control.

[0092] Reference Figure 2, which is a 6G distributed network architecture. The 6G network will be oriented to the diverse scenarios and network performance requirements of deep space, sky (such as satellites), underground, underwater (such as oceans) and land. The centralized network architecture cannot uniformly meet all scenarios. To meet this challenge, the 6G network architecture needs to go beyond centralized control and gradually evolve to a distributed architecture, which will build distributed network nodes with different functions. Multiple distributed network nodes form autonomous distributed micro-networks across domains according to business needs, and provide targeted network services according to specific business scenarios, user scale, geographical environment and other requirements.

[0093] 3. Technical issues

[0094] The network slice instance is defined in the PLMN (Public Land Mobile Network), where the S-NSSAI identifies the network slice. The S-NSSAI includes: a slice service type (SST, Slice / Service Type) and a slice differentiator, where the slice service type refers to the expected network slice behavior in terms of functions and services; the slice differentiator is optional information that supplements the slice service type to distinguish multiple network slices of the same slice service type. Based on the operator's operational or deployment requirements, a network slice instance can be associated with one or more S-NSSAIs, and an S-NSSAI can be associated with one or more network slice instances. Multiple network slice instances associated with the same S-NSSAI can be deployed in the same or different tracking areas. When multiple network slice instances associated with the same S-NSSAI are deployed in the same tracking area, the AMF instance serving the UE can logically belong to more than one network slice instance associated with the S-NSSAI.

[0095] Further, standardized slice service types provide a means to establish global interoperability of slices so that PLMNs can more efficiently support roaming use cases for the most commonly used slice service types.

[0096] Currently, the standardized SST is shown in Table 1 below.

[0097] Table 1

[0098]

[0099] In Table 1, SST is the slice service type, SST value is the identification value corresponding to the slice service type, and Characteristics represents the characteristics of the slice service type.

[0100] Among them, the PLMN does not need to support all SST values ​​in Table 1. The services indicated by each SST value in Table 1 can also be supported by other SSTs. The mapping of network slice types (NEST, Network SliceTypy) defined by the Global System for Mobile Communications Association to standard SST values.

[0101] Furthermore, in the 6G era, business scenarios for users, industries, and families are becoming more and more diverse, and each scenario has more extreme requirements for network performance in all aspects, such as new business scenarios such as telepresence intelligent computing and satellite-ground integration. The slicing method of 5G networks for six types of business scenarios can no longer meet the needs of 6G networks.

[0102] To solve the above problems, the embodiments of the present application provide a communication establishment method, device and storage medium. The method redesigns a network slice division mechanism so that the 6G network can meet the richer business needs of users, industries and other industries. In the 6G distributed network, on the basis of the original 5G slices, new service types of network slices and services within the network nodes are added. At the same time, the network slices can also be divided and set according to the combination of various services to meet the more accurate network slice settings for user services, and establish communications based on the newly divided network slices.

[0103] Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0104] exist Figure 2 Based on the reference Figure 3 , Figure 3 The flowchart of the first communication establishment method provided in the embodiment of the present application includes the following steps:

[0105] S301: Receive a first service establishment request sent by a terminal.

[0106] Among them, referring to Table 2, the first service establishment request carries: network slicing information, the network slicing information is used to indicate the slice service type, and the slice service type includes: perception type, intelligence type, computing type, security type, data type, digital twin type, cross-domain session establishment type, cross-domain switching type, satellite-ground fusion type, type of intelligence and computing combination, satellite-ground fusion and data type. At least one of them.

[0107] In an embodiment of the present application, the network slice information includes: a slice service type, and / or an identification value corresponding to the slice service type, wherein different slice service types correspond to different identification values. Referring to Table 2, the slice service types provided in the present application include, in addition to the slice service types in Table 1, slice service types corresponding to identification values ​​1 to 17.

[0108] Table 2

[0109]

[0110]

[0111] The network does not need to support all SSTs in Table 2. The services indicated by each SST value in Table 2 may also be supported by other SSTs.

[0112] S302, determine the network node corresponding to the network slice information.

[0113] Among them, the determined network node has the function of slicing service type.

[0114] The above network slice settings can be divided into a single slice service type and a single network node, multiple slice service types and a single network node, a single slice service type and multiple network nodes, and multiple slice service types and multiple network nodes.

[0115] S303: Send a second service establishment request to the network node to establish communication between the terminal and the network node.

[0116] Specifically, the second service establishment request includes: network slice information.

[0117] In one embodiment, the slice service type includes: one of a perception type, an intelligence type, a computing type, a security type, a data type, a digital twin type, or a combination of intelligence and computing types, and the number of network nodes is one.

[0118] In an embodiment of the present application, if the slice service type is a combination of intelligence and computing, the first access and mobility management function, the first session management function and the first user plane function of the determined network node can serve both the intelligent type and the computing type.

[0119] The network node includes a first access and mobility management function, a first session management function and a first user plane function; the second service establishment request is used to instruct the first access and mobility management function to determine the first session management function with a slice service type function according to the network slice information, and the first session management function is used to determine the first user plane function with a slice service type function according to the network slice information, so as to establish communication between the terminal and the network node.

[0120] Example 1, reference Figure 4 This embodiment is for when the UE initiates a first service establishment request, the single slice service type is carried, corresponding to the network slice type of a single network node, and includes the following steps:

[0121] S401, first service establishment request.

[0122] Specifically, the terminal sends a first service establishment request to the wireless access network device.

[0123] Among them, the UE initiates a first service establishment request (such as a PDU session establishment request), and the parameters carried by the first service establishment request include: network slice information (including: SST and / or SST value). In addition, the first service establishment request also carries parameters such as session type, session ID, DNN (data network name), SSCmode (session and service continuity mode), etc., among which the SST value in S-NSSAI(s) is 8, which represents a slice requesting an intelligent service, and the access and mobility management functions selected by the RAN when receiving the request also have intelligent functions.

[0124] In this embodiment, the network slice information indication is one of the perception type (SST value is 7), intelligence type (SST value is 8), computing type (SST value is 9), security type (SST value is 10), data type (SST value is 11), digital twin type (SST value is 12), or a combination of intelligence and computing type (SST value is 16).

[0125] S402: Send a second service establishment request.

[0126] Specifically, the wireless access network device sends a second service establishment request to the first access and mobility management function. The wireless access network device determines the first access and mobility management function according to the network slice information, and then sends the second service establishment request to the first access and mobility management function. The first access and mobility management function receives the second service establishment request, parses and obtains the network slice information, and then selects the first session management function with the slice service type function in the network node for session establishment according to the network slice information.

[0127] S403: Session context establishment request.

[0128] Specifically, the first access and mobility management function sends a session context establishment request to the first session management function, wherein the session context establishment request carries session related information and parameters such as network slices.

[0129] S404, query the number of contracted terminals.

[0130] Specifically, the first session management function queries the first subscription data management function for the subscription data of the terminal. The first session management function obtains the subscription data from the first subscription data management function, and then checks whether the network slice information and other parameters requested by the query terminal are allowed according to the subscription data. If allowed, the subsequent user plane function selection is performed according to the network slice information requested by the UE; if the S-NSSAI (s) (network slice information) requested by the UE is not in the subscription data allowed by the UE, a default preset slice service type is selected for the UE to select subsequent user plane functions, or other strategies are executed.

[0131] S405: Send a session context establishment response.
