Abstract

A wireless communication method is performed in a star flash management node. The star flashover management node receives a first message conforming to one of a star flashover communication protocol or a communication protocol of a 5G core network and converts the first message conforming to one of the star flashover communication protocol or the communication protocol of the 5G core network to generate a second message conforming to the other of the star flashover communication protocol or the communication protocol of the 5G core network. The star flash management node sends the second message conforming to the star flash communication protocol or the communication protocol of the 5G core network. The 5G fusion functional unit or the adaptation layer of the star flash management node converts the star flash 5G fusion short-distance message to generate NAS signaling, and then the NAS signaling is transmitted to a 5G core network through an EAP-5G protocol or a GTP-U protocol by a trusted non-3 GPP gateway.

Meanwhile, the development of the 5G technology promotes a large number of intelligent terminals, and brings a large number of wireless short-distance connection intelligent terminals into the market, so that more updated application scenes are derived. Such as typical short-range application scenarios in the fields of smart automobiles, smart manufacturing, smart homes, smart terminals, etc. The new wireless short-range application scene provides new requirements for the wireless short-range communication technology, and covers various aspects such as time delay, reliability, concurrency, information security and the like.

Detailed Description

The invention provides a wireless communication method and a wireless communication device, even in a system architecture of a 5G fusion system type III, a 5G fusion functional unit of a T node does not have NAS function, and a scheme for enabling terminal equipment to support NAS signaling to realize 5G core network management control based on a star flash 5G fusion system is provided.

In the network architecture of the star-flash short-distance technology, nodes in a system are divided into management nodes (called G nodes), managed nodes (called T nodes), in a specific application scene, a single G node manages a certain number of T nodes, and the G nodes and the T nodes are connected together to complete a specific communication function. A single G node and one or more T nodes connected thereto together form a communication domain. Generally, the star flash architecture is formed by connecting a single management node G node with a plurality of managed nodes T nodes, and together forming a communication domain to implement a specific communication function. For example, in an intelligent automobile scene, the automobile domain controller is used as a G node, and a plurality of vehicle-mounted terminals are used as T nodes, so that a communication domain of an intelligent cabin can be formed, and vehicle-mounted video and audio services can be provided for users. In the intelligent home environment, the intelligent large screen is used as a G node, and can be used as a T node with a plurality of sound equipment to form a communication domain, so that high-quality home audio-video service is provided for users. Under the intelligent manufacturing scene, each controller is used as a G node on a single production line of a factory, and is communicated with an actuator and a sensor in a local range as a T node to form a communication domain, so that the accurate control functions of assembly, packaging and the like are realized.

In the currently proposed star-flash and 5G fusion architecture, in order to realize the controllable, reachable and manageable functions of the 5G core network to the T node, when the G node has a 5G fusion functional unit (or a 5G fusion functional module), the G node can participate in the service interaction between the T and the core, or can simply forward the data of the T node only. The definition of the 5G fusion functional unit may refer to the relevant standard of star flash. Herein, a core network (core network) of a 5G communication system may be simply referred to as a 5G core network, a 5G core (5G core,5 gc), a core network, or a core. The network device may also become a network element. An example of a topology map of star-to-5G cellular technology fusion is shown in fig. 1.

Please refer to fig. 1,5G, the core network 30 connects with the G node 20. The G node 20 connects a plurality of T nodes including

T nodes

10a, 10b, and 10c, forms a star flash wireless communication system, and is in one communication domain.

According to the different types and functions of network elements involved in the interaction between the star-flash wireless communication system and the 5G cellular network, the overall 5G fusion system can be divided into three types, and specifically comprises:

type one: the 5G core network supports equipment sensing and interaction of G nodes and T nodes under the coverage of the star flash wireless communication system. The 5G fusion functional unit of the T node is provided with the perception of NAS information, and the G node is a trusted management node and is provided with the 5G fusion functional unit. Namely, the T node and the G node are both provided with 5G fusion functional units.

Type two: the 5G core network only supports the device sensing and interaction of the G node under the coverage of the star flash wireless communication system. The G node is a trusted management node and is provided with a 5G fusion functional unit.

Type three: the 5G core network supports equipment sensing and interaction of G nodes and T nodes under the coverage of the star flash wireless communication system. The 5G fusion function unit of the T node does not have NAS function, the G node is a trusted management node and has the 5G fusion function unit, and the T node is used as a trusted access gateway to access the 5G core network through the trusted management node.

In the current standard version, both the system architecture and registration procedures for type one and type two 5G fusion systems have been concluded. However, the subsequent processes such as the system architecture, the protocol stack, and the registration of the 5G fusion system type three have not been discussed in depth, which results in the need of redesigning the system architecture, the protocol stack, and the registration process of the 5G fusion system type three. Considering that three devices of the type on the market do not support 5G functions (i.e. NAS protocols of N1 and NR-Uu), the 5G core network cannot be directly accessed. The invention mainly aims at the problem, designs a scheme for realizing 5G core network management control by enabling terminal equipment to support NAS signaling based on a star flash 5G fusion system, and enables a core network to identify a far-end terminal (three types of equipment) and interact with instructions correspondingly through enhancement of architecture, protocol improvement, signaling conversion and the like, thereby achieving the purpose of management control. In the embodiment of the invention, the type three equipment can support the transmission of 5G NAS signaling through a trusted star flash access network (Trusted Sparklink Access Network), so that the type three equipment can be used as 5G terminal equipment to run and access a 5G core network.

Referring to fig. 2, the star flash wireless communication system is composed of a star flash access layer 110, the basic service layer 120, and the basic application layer 130. As shown in fig. 2, the star flash access layer 110 may also be referred to as a star flash base layer 101, and the base service layer 120 and the base application layer 130 form a star flash upper layer 102.

The star flash access layer 110 is divided into a management node (called G node) and a terminal node (called T node) according to different implementation functions, wherein the G node provides services of access layers such as connection management, resource allocation, information security and the like for the T node covered by the G node. The star flash access layer 110 realizes transmission interaction of upper layer service data of the G node and the T node on an air interface.

Referring to fig. 3, the star flashnode 20 includes a star flashaccess layer 110a, the basic service layer 120a and the basic application layer 130 a. The star flash access layer 110a may also be referred to as a star flash base layer 101a, and the base service layer 120a and the base application layer 130a form a star flash upper layer 102a. The star-flash node 10 comprises a star-flash access layer 110b, the basic service layer 120b and the basic application layer 130 b. The star flash access layer 110b may also be referred to as a star flash base layer 101b, and the base service layer 120b and the base application layer 130b form a star flash upper layer 102b. Star flashnode 20 may act as a G node. The star flashnode 10 may be referred to as a T node.

Considering that traffic scenarios have differentiated transmission requirements for wireless short-range communications, the star flash access layer 110 currently provides two communication interfaces, namely SparkLink Basic (SLB) 111 (e.g., SLB 111a and SLB 111 b) and Sparklink Low Energy (SLE) 112 (e.g., SLE 112a and SLE 112 b) for the star flash upper layer 102. The SLB 111 uses multiple technologies such as ultrashort frame, multipoint synchronization, bidirectional authentication, fast interference coordination, bidirectional authentication encryption, cross-layer scheduling optimization, etc., to support service scenarios with transmission requirements such as low latency, high reliability, precise synchronization, high concurrency, high security, etc. SLE 112 adopts Polar channel coding to promote transmission reliability, reduces retransmission and saves power consumption, supports maximum 4MHz transmission bandwidth and maximum 8PSK modulation, supports 1-to-many reliable multicast, supports 4KHz short delay interaction and other characteristics, fully considers energy-saving factors while ensuring transmission efficiency as much as possible, and is used for bearing service scenes with low-power consumption requirements. The SLB 111 and SLE 112 provide different transport services for different service requirements, complement each other and continue smooth evolution according to service requirements.

Embodiment two: and a star flash short-distance signaling forwarding step:

based on the first embodiment, referring to fig. 7 and 8, for the T node 10 that does not support NAS, the present invention discloses a method for converting star-flash short-range signaling between the T node 10 and the trusted G node 20 into NAS signaling. Specifically, this embodiment of the method is described in detail below.

The conditions triggering the trusted G-node 20 to perform access to the core network instead of the T-node 10 include: when the T node 10 needs to actively access the 5G core network, or when the 5G core network needs to report a message to the T node 10.

Scheme 1. Based on EAP-5G protocol:

In step 1, the T node 10 encapsulates the star-flash 5G-fusion short message 3081 to be sent by a 5G-fusion star-flash protocol, and transmits the encapsulated short message to the trusted G node 20 through a transmission and adaptation layer (DTAP) and a star-flash access layer (308).

Step 2, the trusted G node 20 receives and parses the star-flash 5G fusion short message 3081 sent by the T node 10 (310), and converts the star-flash 5G fusion short message to generate NAS signaling through the 5G fusion functional unit 201 of the trusted G node 20 or an adaptation layer (Adapter) 202, and then encapsulates the NAS signaling in an EAP-5G packet 3082 (311), and sends the EAP-5G packet 3082 with NAS signaling to the TSLIF gateway 30b through an AAA protocol (312). The star flash 5G converged short range message is used as the first message, and the EAP-5G packet 3082 with NAS signaling is used as the second message. At this time, the trusted G node 20 completes the signaling conversion function.

Step 3, the TSLIF gateway 30b receives the data packet sent by the trusted G node 20 (i.e. the EAP-5G packet 3082 with NAS signaling) and parses NAS signaling (313), and sends the NAS signaling 3083 to the core network element AMF 30c through N2 (314). Specifically, the TSLIF gateway 30b encapsulates NAS signaling 3083 in NG-AP, transmits using SCTP transport protocol, and reaches the core network (including the network device 30a, e.g., AMF 30 c). At this time, NAS signaling received by the core network (including the network device 30a, e.g., AMF 30 c) is identifiable NAS signaling, and the core network (including the network device 30a, e.g., AMF 30 c) knows that this is NAS signaling after packet conversion sent by the T node 10; the TSLIF gateway 30b is trusted to complete the transmission of the signaling sent from the trusted G-node 20.

Step 4, the core network element AMF 30c analyzes the NAS signaling 3083 to complete the access of the T node 10 and provide a mobility management function for the T node 10 (315).

Based on the above steps, the star flash 5G fusion short message of the T node 10 is converted into NAS information that can be identified by the core network through the trusted G node 20, and is transmitted to the core network through the TSLIF gateway 30b, so as to implement management and control of the core network on the T node 10, and complete user registration management, session management, state management, and the like.

Scheme 2. GTP-U protocol based:

In step 1, the T node 10 encapsulates the star-flash 5G fusion short message to be sent by a 5G fusion star-flash protocol, and transmits the encapsulated star-flash short message to the trusted G node 20 through a transmission and adaptation layer (DTAP) and a star-flash access layer (408).

Step 2, the trusted G node 20 receives and parses the star flash 5G fusion short message 4081 sent by the T node 10 (410), converts it by the 5G fusion functional unit 201 of the trusted G node 20 or by the adaptation layer (Adapter) 202 to generate NAS signaling, and then encapsulates the NAS signaling in a GTP-U packet 4082 (411), and sends the GTP-U packet 4082 with NAS signaling to the TSLIF gateway 30b via UDP/IP transport protocol (412). The star flash 5G fuses short range messages as the first message and the GTP-U packet with NAS signaling 4082 as the second message. At this time, the trusted G node 20 completes the signaling conversion function.

Step 3, the TSLIF gateway 30b receives the data packet sent by the trusted G node 20 (i.e. the GTP-U packet 4082 with NAS signaling) and parses NAS signaling (413), and sends NAS signaling 4083 to the core network element AMF 30c through an N2 message (414). Specifically, the TSLIF gateway 30b encapsulates NAS signaling 4083 in NG-AP, and transmits and reaches the core network (including the network device 30 a) using SCTP transport protocol. At this time, NAS signaling received by the core network (including the network device 30a, e.g., AMF 30 c) is identifiable NAS signaling, and the core network (including the network device 30a, e.g., AMF 30 c) knows that this is converted NAS signaling of the T node 10; the TSLIF gateway 30b is trusted to complete the transmission of the signaling to the trusted G node 20.

Step 4, the core network element AMF 30c analyzes the NAS signaling, and completes the access of the T node 10 and provides a mobility management function for the T node 10 (415).

Embodiment three triggering G node initiates registered star flash short distance signaling (IE) to core network:

when the T node 10 needs to access the 5G core network, the trusted G node 20 receives a star-flash 5G converged short message from the T node 10.

The trusted G node 20 generates NAS messages based on the star flash 5G converged short range messages and sends the NAS messages to network devices of the 5G core network.

For example, when the T node 10 wants to access a 5G core network or the network device 30a of the 5G core network needs to wake up the T node 10, because the 5G convergence functional unit of the T node 10 does not support the NAS module, consider triggering the trusted G node 20 through a star flash 5G convergence short distance message), the trusted G node 20 helps the T node 10 initiate a registration request to the 5G core network through the trusted TSLIF gateway 30 b. In this embodiment, the method comprises the following specific steps:

When the T node 10 wants to access a 5G core network or the 5G core network needs to wake up the T node 10, if a star-flash access layer link is not established between the T node 10 and the trusted G node 20, a star-flash access layer link needs to be established between the T node 10 and the trusted G node 20; if a star-flash access layer link exists between the T node 10 and the trusted G node 20, it is not necessary to establish a star-flash access layer link between the T node 10 and the trusted G node 20.

The T node 10 then sends a star-flash 5G converged short range message to the trusted G node 20, wherein the star-flash 5G converged short range message may contain registration request signaling. After receiving the signaling, the trusted G node 20 immediately sends the receiving signaling of the star-flash 5G fusion short-distance message to the T node 10 if a message of a registration request can be created for the T node 10. The T node 10 then sends a star flash 5G converged short message (first message) containing a registration request to the trusted G node 20, while the trusted G node 20 sends a second message containing a registration request to the trusted TSLIF gateway 30 b.

Or to save signaling overhead and reduce latency, the T node 10 sends a star flash 5G fused short message (Sparklink L2 Msg)) to the trusted G node 20 (first message). After the trusted G node 20 receives the signaling, if it is determined that a registration request message can be created for the T node 10, immediately sending a receiving signaling of the star-flash 5G fusion short-distance message to the T node 10, and simultaneously, the trusted G node 20 sends a second message including the registration request to the trusted TSLIF gateway 30 b; conversely, if the trusted G-node 20 cannot create a registration request message for the T-node 10, a flash short range signaling rejection signaling is also immediately sent to the T-node 10.

Based on the above description, the star-flash 5G fusion short-distance message sent by the T node 10 to the trusted G node 20 is a star-flash 5G fusion short-distance message, which is generated by the 5G fusion functional unit of the T node 10, and may trigger the trusted G node 20 to initiate registration signaling (i.e., the NAS message) to the trusted TSLIF gateway 30b, and the star-flash 5G fusion short-distance message may be transmitted through a 5G fusion transmission channel, where the 5G fusion transmission channel may be configured, preconfigured, or predefined by the network device 30a of the core network or the trusted G node 20; second, the star flash 5G fusion short message (Sparklink L2 Msg) may be defined by a new 5G fusion related message alone or may be included in a new 5G fusion related message. The new 5G fusion related message may include a star flash 5G fusion registration request message or a star flash 5G fusion service control class message.

Based on the above, the star flash 5G converged service control class message, or the newly defined star flash 5G converged registration request message, may carry one or more of the following information elements (information element, IE):

the identity TCID of the transmission channel;

star flash quality of service SLQI required for transmission channels

Identifier ID (SUCI/5G-GUTI/PEI, etc.) of the star-flash terminal node (e.g., T node 10);

registration type (initial/period/emergency/mobility);

requested NAASI;

a selected PLMN ID or PLMN list;

registration request message ID;

establishment cause; and

User Equipment (UE) capability information (whether the UE supports NAS) and the like.

For example, the identifier ID of the star flash terminal node 10 may comprise SUCI, 5G-GUTI, or PEI. The registration type of the star flashover terminal node 10 may include initial, periodic, emergency, or mobility. Among the registration types, the "initial" registration type is a registration operation for the star-flash terminal node 10 to initially access the network; the "periodic" registration type is the periodic registration operation of the star-flashing terminal node 10; the "emergency" registration type is a random or emergency registration operation of the star-flashing terminal node 10; "mobility" is a registration operation requiring registration when the star flashover terminal node 10 moves. The user equipment capability information indicates whether the user equipment supports a Non-access stratum (NAS). In an embodiment, the user equipment is the star point terminal node 10.

While the present disclosure has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the present disclosure is not to be limited to the disclosed embodiment, but is intended to cover various arrangements included within the scope of the foregoing broadest interpretation of the appended claims.
