It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. A person of ordinary skill in the art can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems. The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or part of the subject, but are not limited thereto. The subjects shown in FIG1 are examples, and the communication system may include all or part of the subjects in FIG1 , or may include other subjects other than FIG1 , and the number and form of the subjects are arbitrary, and the subjects may be physical or virtual, and the connection relationship between the subjects is an example, and the subjects may be connected or disconnected, and the connection may be in any manner, and may be a direct connection or an indirect connection, and may be a wired connection or a wireless connection. The embodiments of the present disclosure may be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine-to-Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), systems using other communication methods, next-generation systems based on them, etc. In addition, multiple systems can also be combined (for example, a combination of LTE or LTE-A and 5G, etc.) for application. The Internet of Things (IoT) has the potential to connect billions of devices to the Internet, and cellular IoT technologies such as LTE-M and NB-IoT have made significant progress in enabling use cases across a wide range of vertical industries. However, many IoT devices rely on batteries. In some embodiments, IoT technology can include ambient energy harvesting, which can generate electricity from the environment without relying on batteries. With the advantages of ubiquitous future 5th generation (5G) system deployments and abundant system capacity, ambient power enabled IoT technologies offer 5G mobile network operators (MNOs) a potential opportunity to expand the 3rd Generation Partnership Project (3GPP) IoT service portfolio, support new types of devices, and address use cases where battery replacement is considered inefficient and / or environmentally problematic. These use cases include personalized healthcare, smart transportation, industrial applications in hazardous locations, smart logistics, smart warehousing, smart homes, and smart cities. New battery-free devices with limited energy storage capabilities complement existing cellular IoT services and are characterized by low cost, high density, large deployment volumes, and ultra-low complexity, i.e., devices with limited functionality have limited capabilities and require only small and infrequent data transmissions. In some embodiments, the radio (also known as wireless) capabilities of the terminal are stored in an Access and Mobility Management Function (AMF). In some embodiments, when radio capability signaling optimization is not used between the terminal and the network, it is applicable to store the radio capabilities of the terminal in the AMF. In some embodiments, the radio capabilities of the terminal include information about the radio access technologies (RATs) supported by the terminal (e.g., power class, frequency band, etc.). Therefore, this information may be large enough that it is not desirable to change the terminal connection management (CM) state from CM IDLE to CM CONNECTED in the AMF. To avoid this radio capability overhead, the AMF shall store the radio capabilities of the terminal during the CMIDLE state of the terminal and the RM registered state of the terminal. The AMF shall send its latest radio capabilities of the terminal to the access network equipment (RAN) in the N2 request message, i.e., the initial context setup request or the terminal radio capability check request. Terminal capabilities in new radio (NR) rely on a hierarchical structure where each capability parameter is defined per terminal, per duplex mode (frequency division duplex (FDD) / time division duplex (TDD)), per frequency range (FR1 / FR2), per band, per band combination, etc. because a terminal may have different capabilities depending on these capabilities. As the size of terminal radio capabilities increases, driven for example by the additional frequency bands of the universal mobile telecommunications system (UMTS) terrestrial radio access network (Evolved UMTS terrestrial radio access network (E-UTRAN) and NR and their combination, sending over the radio between the terminal and the access network equipment is not efficient. In some embodiments, a method for sending terminal radio capabilities through a radio interface and other network interfaces defined by a resource and admission control sub-system (RACS) can solve the problem of low efficiency of radio transmission between the terminal and the access network device as the scale of the terminal radio capabilities increases. It should be noted that RACS is not applicable to NB-IOT. It is understood that the working principle of RACS is to assign an identifier to represent a set of terminal radio capabilities. This identifier is called the terminal radio capability identification (ID). The terminal radio capability ID can be assigned by the terminal manufacturer or by the public land mobile network (PLMN). The terminal radio capability ID is an alternative method for signaling the terminal radio capabilities through the radio interface, within the next generation radio access network (NG-RAN), from NG-RAN to E-UTRAN, from AMF to NG-RAN, and between CN nodes supporting RACS. In some embodiments, the UE radio capability management function (UCMF) stores all terminal radio capability ID mappings in the PLMN and is responsible for allocating each PLMN-allocated terminal radio capability identifier within the PLMN, see clause 6.2.21. The UCMF stores the UE radio capability ID together with the terminal radio capabilities and the terminal radio capabilities to which they are mapped for paging. Each terminal radio capability ID stored in the UCMF may be associated with TS 36.331

[0051] Associated with one or both of the terminal radio capability formats specified in TS 38.331

[0028] . These two terminal radio capability formats shall be identifiable by the AMF and UCMF. In some embodiments, the terminal radio capability ID is used to uniquely identify a set of terminal radio capabilities (excluding UTRAN and NB-IoT capabilities). The terminal radio capability ID is assigned by the serving PLMN or the terminal manufacturer as follows: Terminal manufacturer allocation: The terminal radio capability ID can be allocated by the terminal manufacturer, in which case it includes the terminal manufacturer identification (i.e., vendor ID). In this case, the terminal radio capability ID uniquely identifies a set of terminal radio capabilities and the terminal radio capabilities of the manufacturer for paging terminals in any PLMN. PLMN allocation: If the terminal radio capability ID assigned by the terminal manufacturer is not used by the terminal or the serving network, or it is not recognized by the serving PLMN UCMF, the UCMF may allocate terminal radio capability IDs for the terminal, which correspond to each different set of terminal radio capabilities that the PLMN may receive from the terminal at different times. In this case, the terminal radio capability ID received by the terminal is applicable to the serving PLMN and uniquely identifies the corresponding set of terminal radio capabilities and terminal paging radio capabilities in that PLMN. The terminal radio capability ID assigned by the PLMN includes a version ID in its format. The value of the version ID is the value configured in the UCMF when the terminal radio capability ID value is assigned. The version ID value enables detection of whether the terminal radio capability ID is current or outdated. It should be noted that, in the case where the PLMN is configured to store the ID assigned by the PLMN in the operation request list assigned by the terminal manufacturer, the algorithm for allocating the terminal radio capability ID assigned by the PLMN should allocate different terminal radio capability IDs to terminals with different tracking area code (TAC) values. In some embodiments, the type of terminal radio capability ID (terminal manufacturer assigned or PLMN assigned) is distinguished when the terminal radio capability ID signal is sent out. Among them, in the current environment, IoT capability negotiation is not supported by terminal radio capability signaling optimization (RACS). In some embodiments, the terminal mobility management (MM) core network capabilities are divided into S1 terminal network capabilities (mainly used for core network parameters related to E-UTRAN access) and terminal 5GMM core network functions (mainly including other terminal capabilities related to interworking with the 5G core network or the Evolved Packet System (EPS)), and include non-radio related capabilities, such as non-access stratum (NAS) security algorithms, etc. The S1 terminal network capabilities are transmitted between all CN nodes from AMF to AMF, AMF to Mobility Management Entity (MME), MME to MME, and MME to AMF changes. UE 5GMM core network capabilities are only transmitted when changing from AMF to AMF. To ensure that the UE MM Core Network Capabilities information stored in the AMF is up to date (e.g. to handle the case when the USIM is moved to a different device when out of coverage and the old device does not send a Detach message; and the case of Inter-RAT Registration Area Update), the terminal shall send the UE MM Core Network Capabilities to the AMF during the Initial Registration and Mobility Registration Update procedures within a NAS message. information. In some embodiments, the terminal shall indicate in the terminal 5GMM core network function whether the terminal supports: In the Evolved Packet Core (EPC), the request type in the additional Packet Data Network (PDN) connection request message is "handover". EPC NAS. Short Message Service (SMS) on NAS. Location Services (LCS). 5G Single Radio Voice Call Continuity (SRVCC) from NG-RAN to UTRAN. Radio Capability Signaling Optimization (RACS). Network slicing-specific authentication and authorization. Network slice replacement. Parameters in network behavior supported by 5G cellular internet of things (CIOT). Receive wake-up signal (WUS) assistance information (E-UTRA). Paging subgroup support indication (NR). Closed access group (CAG). CAG with validity information (if the terminal supports CAG). Limitation on simultaneous registration of network slices based on subscription. Support network slice access layer grouping (Networkslice AS group, NSAG). Partial network slicing support in Random Access (RA). Minimization of service interruption (MINT). Equivalent standalone non-public network (SNPN). . Unavailable period. Supports network reconnection due to RAN timing synchronization status changes. Network controlled slices use endpoint configuration of policies. Temporarily available network slices. Supports S-network slice selection assistance information (NSSAI) location availability information. If a terminal operating two or more Universal Subscriber Identity Modules (USIM) supports and intends to use one or more multi-USIM features for USIM in a PLMN, it shall indicate in the terminal 5GMM Core Network Capabilities of the USIM in the PLMN that it supports the one or more multi-USIM features with the following indications: Supports connection version. Supports paging reason indication for voice services. Supports rejecting paging requests. Support paging restrictions. Otherwise, a UE that has the capability of multiple USIM features but does not intend to use them shall not indicate support for one or more of these multiple USIM functions. Terminals that do not operate two or more USIMs shall indicate that the multi-USIM functionality is not supported. It should be noted that a terminal operating two or more USIMs does not necessarily need to use the multi-USIM function for all USIMs. In some embodiments, the terminal 5G session management information (SM) core network function is included in the packet data unit (PDU) session establishment / modification request. The UE shall specify in the UE 5GSM core network functions whether the UE supports: - PDU session type "Ethernet" supported in Evolved Packet Core (EPC) as PDN type "Ethernet"; -Reflective Quality of Service (QoS); - Multi-homed IPv6 PDU sessions (only if the requested PDU type is set to "IPv6" or "IPv4v6"); -Access Traffic Steering, Switching and Splitting (ATSSS) capability; - Port management information on container transfers. If necessary, during the PDU session establishment / modification process, the 5GSM core network function will be transferred from the roaming session management function entity V-SMF to the receiving home session management function entity H-SMF. After a PDU session established in an Evolved Packet System (EPS) is first inter-system changed from EPS to 5GS, if there is reflective QoS and / or multi-homed IPv6 PDU session, the 5GSM core network functions are also included in the PDU session modification. There is no clear way how to send the terminal's capability information to the network.

It can be understood that when the first information sent by the terminal to the first network element needs to be used to indicate the identification information corresponding to the radio capabilities possessed by the terminal, if the terminal itself only has the radio capabilities possessed by the terminal, in this case, the terminal can send a request message to the first network element, requesting to obtain the identification information corresponding to the radio capabilities possessed by the terminal.
