Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0057] The technical solutions described in the embodiments of this application can be combined arbitrarily without conflict. In the description of this application, "multiple" means two or more, unless otherwise clearly defined.

As shown in Figure 1 , communication system 100 may include terminal device 110, access network device 120, and core network device 130. Access network device 120 can communicate with terminal device 110 via an air interface. Multi-service transmission is supported between terminal device 110 and access network device 120.

[0059] It should be understood that the embodiments of the present application are only illustrative of the communication system 100, but the embodiments of the present application are not limited thereto.

[0064] It should be noted that Figure 1 is merely an example of a system applicable to this application. Of course, the methods described in the embodiments of this application can also be applied to other systems. Furthermore, the terms "system" and "network" are often used interchangeably herein. The term "and / or" herein simply describes an association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the associated objects are in an "or" relationship. It should also be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association relationship. For example, "A indicates B" can mean that A directly indicates B, for example, B can obtain information through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can obtain information through C; or it can mean that A and B have an association relationship. It should also be understood that the "correspondence" mentioned in the embodiments of this application can mean that there is a direct or indirect correspondence between two objects, or that there is an association relationship between the two objects, or a relationship between an indicator and the indicated, a configuration and the configured, and so on. It should also be understood that the “predefined”, “protocol agreement”, “predetermined” or “predefined rules” mentioned in the embodiments of the present application can be implemented by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in devices (for example, including terminal devices and network devices). This application does not limit its specific implementation method. For example, predefined can refer to what is defined in the protocol. It should also be understood that in the embodiments of the present application, the “protocol” may refer to a standard protocol in the field of communications, for example, it may include LTE protocols, NR protocols, and related protocols used in future communication systems, and this application does not limit this.

[0070] To facilitate understanding of the technical solutions of the embodiments of the present application, the technologies related to the embodiments of the present application are described below. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0071] FIG2 is a schematic diagram of a system architecture based on a reference point presentation method provided in an embodiment of the present application. As shown in FIG2 , the reference point presentation method can indicate that there can be interaction between corresponding network function (NF) services. Network functions include, for example, access and mobility management function (AMF) 201, session management function (SMF) 202, policy control function (PCF) 203, application function (AF) 204, user plane function (UPF) 205, network slice selection function (NSSF) 206, authentication server function (AUSF) 207, and unified data management (UDM) 208. The system may also include: UE 209, radio access network (RAN) or access point (AN) 210, and data network (DN) 211.

[0072] Figure 2 shows the following reference points: N1 (between UE 209 and AMF 201), N2 (between RAN 210 and AMF 201), N3 (between RAN 210 and UPF 205), N4 (between SMF 202 and UPF 205), N5 (between PCF 203 and AF 204), N6 (between UPF 205 and DN 211), N7 (between SMF 202 and PCF 203), N8 (between UDM 208 and AMF 201), N9 (between two UPFs 205), N10 (between UDM 208 and SMF 202), N11 (between AMF 201 and SMF 202), N12 (between AUSF 207 and AMF 201), N13 (between AUSF 207 and UDM 208), N14 (between two AMFs 201), N15 (between PCF 203 and AMF 201 in the case of non-roaming scenario, or between PCF 203 and visited network and AMF 201 in the case of roaming scenario), N16 (between two SMFs; not shown) and N22 (between AMF 201 and NSSF 206).

[0073] The following describes SMF, PCF, and AF:

[0074] SMF: includes session establishment, modification and release, tunnel maintenance between UPF and AN nodes, terminal Internet Protocol (IP) address allocation and management, selection and control of UPF functions, billing data collection and billing interface support, etc.

[0075] PCF: Supports a unified policy framework to manage network behavior and provides operator network control policies to other network elements and terminals.

[0076] AF: This can be an internal carrier application, such as the IP Multimedia Subsystem (IMS), or a third-party service, such as web services, videos, or games. If the carrier's internal AF is in the same trusted domain as other NFs, it can interact directly with other NFs. If the AF is not in a trusted domain, it requires the network exposure function (NEF) to access other NFs.

[0077] The UE establishes an access layer connection with the AN through the Uu port, exchanging access layer messages and wireless data transmission. The UE establishes a non-access stratum (NAS) connection with the AMF through the N1 port, exchanging NAS messages. The AMF is the mobility management function in the core network, and the SMF is the session management function in the core network. In addition to managing UE mobility, the AMF is also responsible for forwarding session management-related messages between the UE and the SMF. The PCF is the policy management function in the core network, responsible for formulating policies related to UE mobility management, session management, and billing. The UPF is the user plane function in the core network, transmitting data with the external data network through the N6 interface and with the AN through the N3 interface.

[0078] In a radio frequency identification (RFID) system, a reader / writer is a device that reads or writes information from an electronic tag. During operation, the reader / writer transmits radio frequency energy within an area, creating an electromagnetic field. The size of this area depends on the transmission power. Electronic tags within the reader / writer's coverage area are triggered to transmit stored data or modify it according to the reader / writer's instructions. The reader / writer uses radio frequency (RF) to conduct contactless, two-way data communication with the electronic tag, reading and writing to the tag, thereby achieving target identification and data exchange. Electronic tags generally consume little power and may not even require a power source or battery. For example, passive electronic tags can receive microwave signals from the reader / writer and obtain energy through electromagnetic induction coils to temporarily power themselves and complete information exchange. RFID has a short transmission range and is therefore used for local management and communication of items, such as in warehouses, archives, access card management, and electronic highway toll payment.

[0079] The 3rd Generation Partnership Project (3GPP) is also considering designing new electronic tags, called Passive IoT tags or Ambient IoT tags. Unlike RFID, these tags can communicate using the frequency resources of the 3GPP network. The electronic tags in the present invention include, but are not limited to, RFID tags, Passive IoT tags, and Ambient IoT tags.

[0080] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments.
