The system can also include a core network part, such as an evolved packet system (Evloved Packet System, EPS), a 5G system (5GS), etc. The terminal involved in the embodiments of the present disclosure may be a device that provides voice and / or data connectivity to a user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem. In different systems, the name of the terminal may also be different. For example, in a 5G system, the terminal may be called a user equipment (UE). The terminal can communicate with one or more core networks (CN) via a radio access network (RAN). The terminal may be a mobile terminal, such as a mobile phone (or a "cellular" phone) and a computer with a mobile terminal. For example, it may be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges language and / or data with a radio access network. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs) and other devices. A wireless terminal may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, or a user device, but is not limited to these terms in the embodiments of the present disclosure. The network device involved in the embodiments of the present disclosure may be a base station, which may include multiple cells providing services for the terminal. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in the access network that communicates with the wireless terminal through one or more sectors on the air interface, or other names. The network device may be used to interchange received air frames with Internet Protocol (IP) packets, and serve as a router between the wireless terminal and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) communication network. The network device may also coordinate the attribute management of the air interface. For example, the network device involved in the embodiments of the present disclosure may be a network device (Base Transceiver Station, BTS) in the Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), or a network device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or an evolutionary network device (eNB or e-NodeB) in the long term evolution (LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), or a home evolved Node B (HeNB), a relay node, a femto, a pico, etc., which is not limited in the embodiments of the present disclosure. In some network structures, the network devices may include centralized unit (CU) nodes and distributed unit (DU) nodes. Points, centralized units and distributed units may also be geographically separated. Network devices and terminals can each use one or more antennas for MIMO transmission. MIMO transmission can be single-user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO). Depending on the form and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO or massive-MIMO, or it can be diversity transmission, precoded transmission or beamforming transmission, etc. In order to understand the present disclosure more clearly, first, some technical terms involved in the present disclosure are explained: 1. Terminal capabilities. Terminal capabilities include terminal network capabilities and terminal wireless capabilities. Whether it is the access network or the core network, many optional functions or optional algorithms are defined in each standard. The core network needs to allocate appropriate resources, functions and algorithms to the terminal according to its capabilities. When the network side makes various event decisions or executes various algorithms, it needs to know the capabilities of the terminal in order to make the most appropriate decisions. For example, if the terminal supports circuit switched fallback (CSFB) to initiate joint attachment, the network side will execute and process it differently; if the terminal does not support the interoperability (Inter-Radio Access Technology, Inter-RAT) mobility (mobility) between different radio access technologies of packet switching (PSHO), the network side adopts network assisted cell change (NACC) / cell change order (CCO) or redirection (Redirect) to realize the operation between systems. Therefore, since the terminal capabilities are different and vary greatly, the network side needs to know the terminal capabilities, which requires that the terminal capabilities can be reported and synchronized in some way. 2. Terminal network capabilities: When the terminal is first connected, the terminal capability information is carried to AMF through the registration request message; when the terminal network capability information changes, the latest terminal capability information can be carried to AMF through the registration update (non-periodic) request; when the terminal capability information changes and the terminal is in the registered state, the terminal needs to first adjust the state to the unregistered state, and then initiate the registration update process to carry the latest terminal capability information to AMF, which manages the terminal capability information. Specific terminal network capabilities include: (1) Security capabilities supported by the terminal: In order to negotiate the security of the non-access stratum (NAS) between the terminal and the mobile management entity (MME), the terminal needs to report its security capability information to the MME; (2) Capability to support extended protocol configuration options: If the UE supports the narrowband S1 interface (NB-S1) mode or the non-IP public data network (Non-IP PDN) type, the extended protocol configuration options (ePCO) field of the UE Network Capability Information Element shall be filled with “extended protocol configuration options supported” (i.e., support for extended protocol configuration options); (3) Restriction on use of enhanced coverage capability: If the terminal supports the capability of restricted use of enhanced coverage, the restriction on use of enhanced coverage (RestrictEC) field of the terminal network capability information element shall be filled with "restriction on use of enhanced coverage supported" (i.e., support for restricted use of enhanced coverage); (4) Control plane data back-off timer T3448: If the terminal supports control plane data congestion control, the control plane back-off (CP backoff) field of the terminal network capability information element is filled with "back-off timer for transport of user data via the control plane supported" (i.e., the back-off timer for transport of user data via the control plane supported); (5) Optimization of the control plane Cellular Internet of Things Evolved Packet System (CIoT EPS): If the terminal is in NB-S1 mode, the control plane Cellular Internet of Things Evolved Packet System (CIoT EPS) of the terminal network capability information element The control plane CIoT EPS optimization field is filled with “control plane CIoT EPS optimization supported” (i.e., support for control plane CIoT EPS optimization); (6) Evolved packet system Mobility Management (EMM) registered without PDN connection (EMM-REGISTERED without PDN connection, ERwPDN): If the terminal supports CIoT optimization, it is necessary to indicate whether the EMM-REGISTERED without PDN connection capability is supported in the ERwPDN bit of the terminal network capability information; (7) S1-U data transfer: This option is only for NB-S1 mode. Unlike traditional LTE where data can only be transferred via S1-U, data in NB-S1 mode can be transferred via both S1-U and the control plane. If the terminal supports S1-U transfer, the S1-U data bit of the terminal network capability information element is filled with "S1-U data transfer supported" (i.e., supports S1-U data transfer). (8) Multiple user plane radio bearers: This option is only for NB-S1 mode. If the terminal supports S1-U transmission and supports the establishment of multiple user plane radio bearers, the multiple data radio bearers support (multiple DRB support) field of the terminal network capability information element is filled with "Multiple DRB supported". 3. Terminal wireless capabilities. The terminal wireless capabilities are relatively large and should not be frequently transmitted over the air interface, so the terminal capability information is generally stored in the AMF. When the terminal capability information changes, the terminal notifies the registration update and notifies the AMF of the terminal capability information change message, thereby triggering the AMF to update the terminal capability information. Specific terminal wireless capabilities include: (1) Access Stratum Release: the 3rd Generation Partnership Project (3GPP) version supported by the terminal; (2) UE Category: The transmission capability of a terminal is determined by the UE Category between the base station and the terminal. (3) Packet Data Convergence Protocol (PDCP) parameters: Robust header compression (ROCH) capability of the terminal; (4) Radio frequency (RF) Parameters: The terminal's RF capabilities, indicating the band indication and duplex mode supported by the terminal; (5) Measurement capability of the terminal: whether call gap is required. 4. Terminal capability query and reporting. After the base station determines the terminal capability (UE Capability), it can correctly schedule the terminal; if the terminal supports a certain function, the base station can configure the function for the terminal; if the terminal does not support a certain function, the base station cannot configure the function for the terminal. Figure 1 is a schematic diagram of the process of terminal capability query and reporting provided by the relevant technology. As shown in Figure 1, terminal capability query and reporting mainly involve two processes: UE Capability request and UE Capability reporting, which specifically include the following steps: S101. When the base station requires the terminal to report UE Capability, the base station (corresponding to the network side in FIG. 1 ) sends a terminal capability query (UECapabilityEnquiry) instruction to the terminal; correspondingly, the terminal receives the UECapabilityEnquiry instruction. S102. The terminal sends the terminal capability information (UECapabilityInformation) to the base station according to the UECapabilityEnquiry instruction. 5. UE Category. The original intention of 3GPP to formulate LTE standards was to provide different levels of network service capabilities for different users. Therefore, the concept of UE Category was proposed in LTE: different services use different UE Categories, and the network provides different bandwidths and rates. "Cat" is the abbreviation of Category. According to the definition of 3GPP, UE Category stands for User Equipment level, indicating The uplink and downlink data transmission capabilities supported by the terminal. UE Category can be abbreviated as UE Cat, or also called terminal capability level. With the evolution of 4G LTE technical specifications, each update will introduce some new technologies and new UE Cat values. The earliest version of 4G is Release 8 (R8), followed by R9, R10, R11, R12, R13, R14, etc. (5G terminal capability levels are defined from R15). From R8 to R11, 3GPP defined terminal capability levels from Cat1 to Cat12. In R12, the defined terminal capability levels began to carry downlink (DL) and uplink (UL), where DL represents the terminal's download capability and UL represents the terminal's upload capability. 6. UEradio Capability Management Functions (UCMF), which is used to store dictionary entries corresponding to UE radio capability identities (IDs) assigned by the Public Land Mobile Network (PLMN) or by the UE manufacturer. The MME can subscribe to the UCMF to obtain new values ​​of the UE radio capability ID from the UCMF, which allocates these new values ​​in order to cache them locally. Provisioning of UE manufacturer assigned UE Radio Capability ID entries in UCMF is performed from the Access Stratum (AS) interacting with UCMF directly or through Service Creation Environment Function (SCFF) (or through network management). UCMF serving both EPS and 5GS shall use TS 38.331 on request

[0089] The UE radio capability ID is provided in the TS 36.331

[0037] (a version number of a protocol specifying the format of a UE radio capability ID) format or in both formats of the UE radio capabilities. For UE radio capability IDs assigned by PLMN, UCMF is also the entity that assigns UE radio capability identification values. Each UE radio capability ID assigned by PLMN is also associated with the International Mobile Equipment Identity (IMEI) / Tracking Area Code (TAC) of the UE model it is associated with. When the MME requests UCMF to assign UE radio capability identities for a set of UE radio capabilities, it indicates the IMEI / TAC of the UE to which the UE radio capability information is related. UCMF can be equipped with a dictionary of UE radio capability IDs assigned by UE manufacturers, which includes the "Vendor ID" of the manufacturer that applies to these UEs, and a list of IMEI / TACs to which the PLMN has obtained UE radio capability IDs assigned by the UE manufacturer. The PLMN assigned UE radio capability ID is maintained in the UCMF memory as long as it is associated with at least the IMEI / TAC value. When the IMEI / TAC value is associated with a UE model specified for operation based on the UE radio capability ID assigned by the UE manufacturer, in the UCMF, this IMEI / TAC value is disassociated from any PLMN assigned UE radio capability ID. For the case where the PLMN is configured to store the PLMN assigned ID in the UE manufacturer assigned operation request list, the UCMF will not delete any PLMN assigned UE radio capability ID that is no longer in use from the UE manufacturer assigned operation request list, but will isolate it to avoid any future reallocation. The UCMF stores the version ID value of the PLMN assigned UE radio capability ID so that it is included in the PLMN assigned UE radio capability ID it assigns. This should be configured in the UCMF. The UCMF dictionary entries shall also include the relevant UE radio capabilities for paging for each Radio Access Technology (RAT). With the development of RAN service, the anchor point between the core network and RAN is no longer AMF. RAN can exchange signaling and establish processes with any core network element (Network Function, NF) in need. For example, RAN and AMF can exchange processes related to mobility, RAN and Session Management Function (Session Management Function, SMF) can exchange processes related to session, RAN and Location Management Function (Location Management Function, LMF) can exchange processes related to positioning, etc. Moreover, with the upgrade of the network and the emergence of new services, the terminal has The capabilities of RAN are also increasing, such as terminal data processing capabilities, perception capabilities, AI capabilities, computing capabilities, and satellite communication capabilities. Therefore, the terminal capabilities are stored and managed through AMF, while other core network elements do not perceive the terminal capabilities. This can no longer meet the system requirements under RAN service-oriented, and there is a situation where normal business cannot be carried out. Therefore, a terminal capability management solution under RAN service-oriented is urgently needed. To solve the above problems, the embodiments of the present disclosure provide a method, device and storage medium for managing terminal capabilities under RAN service. In the present disclosure, a new access network element can be added to store and manage terminal network capability information and terminal wireless capability information. When performing relevant signaling processes, if other network elements need it, a terminal capability acquisition request can be initiated to the access network element to obtain terminal capabilities. Alternatively, the terminal capabilities are stored and managed by the core network element that needs to interact directly with the RAN, that is, stored and managed by multiple core network elements at the same time, such as AMF, SMF and LMF. Alternatively, the terminal capabilities are still stored and managed by AMF, but other core network elements need to subscribe to the terminal capabilities from AMF. When AMF receives the reported terminal capabilities, it needs to send the terminal capabilities to the core network element to which it subscribes the terminal capabilities, thereby ensuring that when RAN and other core network elements interact, the most appropriate decision can be determined in combination with the terminal capabilities. The embodiments of the present disclosure enable each core network element to initiate the corresponding business process based on the terminal capabilities, ensuring the normal progress of each business process under RAN service. Exemplarily, FIG2 is a schematic diagram of managing terminal capability information through a newly added access network element provided in an embodiment of the present disclosure. As shown in FIG2, the newly added access network element is named, for example, UE Capability Management Function (UE Capability Management Function, UECMF). The terminal capabilities reported by the terminal are stored and managed through UECMF. Core network elements such as AMF, SMF, LMF, Policy Control Function (Policy Control Function, PCF) and Network Slice Select Function (NSSF) subscribe to the terminal capability information from UECMF. The embodiment of the present disclosure does not limit the deployment location of UECMF. UECMF can be a service function after RAN serviceization or a separate functional module. FIG3 is a schematic diagram of managing terminal capability information through a core network element provided in an embodiment of the present disclosure. As shown in FIG3, the terminal capability information reported by the terminal is stored and managed through core network elements (such as AMF, SMF, LMF, PCF and NSSF, etc.) that directly interact with RAN. Figure 4 is a schematic diagram of managing terminal capability information through AMF provided by an embodiment of the present disclosure. As shown in Figure 4, the terminal capability information reported by the terminal is stored and managed by AMF, and other core network elements such as SMF, LMF, PCF and NSSF subscribe to the terminal capability information from AMF. It should be noted that the method and device provided in the embodiments of the present disclosure are based on the same application concept. Since the method and device solve the problem in a similar manner, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated. In the following, the application scenarios of the solutions provided by the present disclosure are firstly described by examples. FIG5 is a schematic diagram of an application scenario provided by an embodiment of the present disclosure. As shown in FIG5 , with reference to FIG2 , this embodiment takes a newly added access network element (i.e., UECMF) for storing and managing terminal capabilities as an example. Terminal 501 ((FIG5 takes three terminals 501 as an example) initiates a registration request to base station 502 (i.e., RAN), and base station 502 sends the registration request to core network element AMF; AMF subscribes to terminal capability information from access network element UECMF deployed in base station 502, and AMF determines the security algorithm of terminal 501 and core network based on the subscribed terminal capability information. It should be noted that FIG. 5 is merely a schematic diagram of an application scenario provided by an embodiment of the present disclosure. The embodiment of the present disclosure does not limit the devices included in FIG. 5 , nor does it limit the positional relationship between the devices in FIG. 5 . The following specific embodiments are used to describe in detail the technical solutions of the embodiments of the present disclosure and how the technical solutions of the embodiments of the present disclosure solve the above technical problems. The following specific embodiments can be implemented independently or in combination with each other. In some embodiments, the same or similar concepts or processes may not be described in detail. FIG6 is a flow chart of a method for managing terminal capabilities under RAN service-oriented services provided by an embodiment of the present disclosure, wherein the first network element is an access network element under RAN service-oriented services, or the first network element is a core network element under RAN service-oriented services. As shown in FIG6 , the method for managing terminal capabilities under RAN service-oriented services in an embodiment of the present disclosure includes: S601: The terminal obtains terminal capability information. In the embodiment of the present disclosure, the terminal obtains terminal capability information locally, and the terminal capability information is, for example, terminal capability information generated by a user setting the terminal. Optionally, the terminal capability information includes terminal network capability information and terminal wireless capability information. Exemplarily, the terminal network capability information is, for example, the security capability information supported by the terminal in the above embodiment, whether the terminal supports the extended protocol configuration option, and whether the terminal supports the capability of enhancing coverage restriction use, etc. The terminal wireless capability information is, for example, the terminal level information used to determine the terminal transmission capability, the ROCH capability information of the terminal, and the radio frequency capability information of the terminal, etc. Further, optionally, the terminal capability information also includes at least one of the following: perception capability information, AI capability information and computing capability information. It can be understood that in addition to terminal network capability information and terminal wireless capability information, terminal capability information can also include new capability information such as perception capability information, AI capability information and computing capability information. S602. The terminal sends terminal capability information to the first network element. Correspondingly, the first network element receives the terminal capability information sent by the terminal. In this step, after obtaining the terminal capability information, the terminal can send the terminal capability information to the first network element, and accordingly, the first network element receives the terminal capability information sent by the terminal. Exemplarily, referring to Figure 2, the first network element is the access network element UECMF under RAN service, and the UECMF receives the terminal capability information sent by the terminal. Referring to Figure 3, the first network element is a core network element that directly interacts with the RAN under RAN service, and the core network element receives the terminal capability information sent by the terminal. Referring to Figure 4, the first network element is the AMF under RAN service, and the AMF receives the terminal capability information sent by the terminal. S603: The first network element manages the terminal capability information. Exemplarily, referring to FIG. 2 , after receiving the terminal capability information sent by the terminal, the UECMF may manage the terminal capability information, such as storing the terminal capability information and sending the terminal capability information to the core network element that has subscribed to the terminal capability. Optionally, the terminal capability information is represented in the form of terminal levels, and / or the terminal capability information is represented in the form of terminal network capability information elements. Exemplarily, the terminal capability information can be represented by a terminal class (UE Category), and for new terminal capabilities, a corresponding terminal class can be added. When a terminal reports a new terminal capability, it can be carried to the first network element for managing terminal capabilities through signaling. For example, Category A can be used to indicate that the terminal has data processing capabilities, Category B can be used to indicate that the terminal has perception capabilities, Category C can be used to indicate that the terminal has AI capabilities, Category D can be used to indicate that the terminal has computing capabilities, and Category E can be used to indicate that the terminal has a combination of multiple new capabilities. Exemplarily, the terminal capability information can be represented by a terminal network capability information element (UE Network Capability IE), and for new terminal capabilities, a corresponding terminal network capability information element can be added. When a terminal reports a new terminal capability, it can be carried to the first network element for managing terminal capabilities through signaling. In the disclosed embodiment, the terminal capability information is obtained through the terminal, and the terminal sends the terminal capability information to the first network element. Correspondingly, the first network element receives the terminal capability information sent by the terminal and manages the terminal capability information. Among them, the first network element is an access network element under RAN service, or the first network element is a core network element under RAN service, that is, the terminal capability information can be managed through the access network element under RAN service, or the terminal capability information can be managed through the core network element under RAN service, instead of managing the terminal capability information through AMF in the current related technology. The disclosed embodiment enables each core network element to obtain the terminal capability information from the first network element, thereby initiating the corresponding business process based on the terminal capability information, and ensuring the normal operation of each business process under RAN service. On the basis of the above embodiments, in some embodiments, the first network element is an access network element, the second network element is a core network element under RAN service, the second network element subscribes to the terminal capability information from the access network element, and the first network element manages the terminal capability information, which may include: the first network element sends the terminal capability information to the second network element. Correspondingly, the second network element receives the terminal capability information sent by the first network element and manages the terminal capability information. Exemplarily, taking the initial access of a terminal to a network as an example, FIG7 is a flow chart of the second method for managing terminal capabilities under RAN service-oriented services provided by an embodiment of the present disclosure. As shown in FIG7 , the first network element is an access network element UECMF, and the second network element is a core network element under RAN service-oriented services. For example, the second network element is an AMF, SMF, and LMF under RAN service-oriented services. The method for managing terminal capabilities under RAN service-oriented services in an embodiment of the present disclosure may include: S701. The second network element sends a terminal capability information subscription request to the UECMF. S702. The terminal sends an uplink message transfer (UL Message Transfer) request to the UECMF. The request carries terminal capability information, and the terminal capability information includes terminal network capability information and terminal wireless capability information. S703. UECMF sends a downlink message transfer (DL Message Transfer) response to the terminal. S704. UECMF saves the received terminal capability information. S705, the UECMF sends a terminal capability information subscription response to the second network element, and sends the terminal capability information to the second network element that subscribes to the terminal capability information. Correspondingly, the second network element receives the terminal capability information sent by the UECMF. S706. The second network element manages the terminal capability information. Optionally, subscribing to the terminal capability information may include subscribing to all terminal capability information or subscribing to the terminal capability information corresponding to the service demand. It can be understood that the second network element can subscribe to all terminal capability information from the access network element, or can subscribe to the terminal capability information corresponding to the service demand from the access network element, and the embodiments of the present disclosure do not limit this. For example, assuming that the second network element is SMF, the SMF can only subscribe to the terminal capability information related to the session according to the service demand; assuming that the second network element is LMF, the LMF can only subscribe to the terminal capability information related to positioning according to the service demand. Optionally, the second network element can subscribe to the terminal capability information in advance (such as when the second network element is just started) or when the second network element needs it, and the embodiments of the present disclosure do not limit this. Based on the above embodiment, in one example, the terminal capability information sent by the terminal and received by the access network element includes the terminal network capability information, and the access network element manages the terminal capability information, which may include: the access network element sends a first query request to the terminal, and the first query request is used to query the terminal wireless capability information. Accordingly, the terminal receives the first query request sent by the access network element, obtains the terminal wireless capability information, and sends the terminal wireless capability information to the access network element. Accordingly, the access network element receives the terminal wireless capability information sent by the terminal and manages the terminal wireless capability information. It can be understood that in this embodiment, the terminal capability information sent by the terminal and received by the access network element only includes the terminal capability information. Terminal network capability information is included, but terminal wireless capability information is not included. Exemplarily, taking the initial access of the terminal to the network as an example, FIG8 is a flow chart of the terminal capability management method under RAN service-oriented provided by the embodiment of the present disclosure. As shown in FIG8, the first network element is the access network element UECMF, and the second network element is the core network element under RAN service-oriented. The second network element is, for example, AMF, SMF and LMF under RAN service-oriented. The terminal capability management method under RAN service-oriented in the embodiment of the present disclosure may include: S801. The second network element sends a terminal capability information subscription request to the UECMF. S802. The terminal sends an uplink message transmission request to the UECMF, where the request carries the terminal network capability information. S803. The UECMF determines that the request does not include the terminal wireless capability information, and sends a first query request to the terminal, where the first query request is used to query the terminal wireless capability information. S804: The terminal sends the terminal wireless capability information to the UECMF. Correspondingly, the UECMF receives the terminal wireless capability information sent by the terminal. S805.
