[0040] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present application.

[0041] The following will describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are 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.

[0042] The technical solutions of the embodiments of the present application can be applied to various communication systems, for example: Global System of Mobile communication (GSM), Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS) system, Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD) system, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system or 5G system, etc.

[0043] For example, the communication system 100 used in the embodiment of the present application can be as follows: Figure 1-1As shown. The communication system 100 may include a network device 110, which may be a device that communicates with a UE 120 (or a communication terminal device, a terminal device). The network device 110 may provide communication coverage for a specific geographical area, and may communicate with a UE located in the coverage area. In one embodiment, the network device 110 may be a network device (Base Transceiver Station, BTS) in a GSM or CDMA system, or a network device (NodeB, NB) in a WCDMA system, or an evolved network device (Evolutional Node B, eNB or eNodeB) in an LTE system, or a wireless controller in a cloud radio access network (Cloud Radio Access Network, CRAN), or the network device may be a mobile switching center, a relay station, an access point, a vehicle-mounted device, a wearable device, a hub, a switch, a bridge, a router, a network side device in a 5G network, or a network device in a future evolved public land mobile network (Public Land Mobile Network, PLMN), etc.

[0044] The communication system 100 also includes at least one UE 120 located within the coverage of the network device 110. As used herein, "UE" includes but is not limited to being connected via a wired line, such as via a Public Switched Telephone Networks (PSTN), a Digital Subscriber Line (DSL), a digital cable, a direct cable connection; and / or another data connection / network connection; and / or via a wireless interface, such as, for a cellular network, a Wireless Local Area Network (WLAN), a digital television network such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter connection; and / or via another UE's device that is configured to receive / send communication signals; and / or a UE connected by an Internet of Things (IoT) device. A UE that is configured to communicate via a wireless interface may be referred to as a "wireless communication terminal device", a "wireless terminal device" or a "mobile terminal device".

[0045] In one embodiment, UE 120 may perform device to device (D2D) communication between the UEs.

[0046] In the related technologies, the main application scenarios of 5G are: Enhanced Mobile Broadband (eMBB), Ultra-Reliable and Low-Latency Communication (URLLC), and Massive Machine Type Communication (mMTC). Among them, eMBB still aims at users to obtain multimedia content, services and data, and its demand is growing rapidly. On the other hand, since eMBB may be deployed in different scenarios, such as indoors, urban areas, and rural areas, its capabilities and requirements are also quite different, so it cannot be generalized and must be analyzed in detail in combination with specific deployment scenarios. Typical applications of URLLC include: industrial automation, power automation, remote medical operations (surgery), traffic safety, etc. Typical characteristics of mMTC include: high connection density, small data volume, latency-insensitive services, low cost and long service life of modules, etc.

[0047] NR can also be deployed independently. In order to reduce air interface signaling and quickly restore wireless connections and data services in the 5G network environment, a new Radio Resource Control (RRC) state is defined, namely the RRC_INACTIVE (inactive) state. This state is different from the RRC_IDLE (idle) and RRC_ACTIVE (active) states.

[0048] RRC_IDLE: Mobility is based on UE cell selection and reselection, paging is initiated by the core network (CN), and the paging area is configured by the CN. There is no UE AS (Access Stratum) context on the base station side. There is no RRC connection.

[0049] RRC_CONNECTED: An RRC connection exists, and a UE AS context exists between the base station and the UE. The network knows the location of the UE at a specific cell level. Mobility is controlled by the network. Unicast data can be transmitted between the UE and the base station.

[0050] RRC_INACTIVE: Mobility is based on UE cell selection and reselection, there is a connection between CN and NR, the UE AS context exists on a certain base station, paging is triggered by the Radio Access Network (RAN), the RAN-based paging area is managed by the RAN, and the network side knows the UE's location based on the RAN paging area level.

[0051] The network side can control the state transition of the UE, see Figure 1-2, RRC is in the inactive state. The UE returns to the idle state autonomously in the following situations: when receiving the CN initial paging message; when initiating an RRC recovery request, starting timer T319, if the timer times out; when MSG4 integrity protection verification fails; when the cell reselects to other RAT; entering the camp on any cell state.

[0052] Figure 1-3 The RAN in RRC_INACTIVE state is shown. The characteristics of the RRC_INACTIVE state are as follows:

[0053] It is the state maintained when the connection between RAN and CN is maintained;

[0054] The UE and at least one gNB store the AS context;

[0055] The UE is reachable to the RAN side, and related parameters are configured by the RAN.

[0056] When the UE moves within the RAN Notification Area (RNA) configured by the RAN, it does not need to notify the network side, but when it moves out of the RNA, it needs to notify the network side; the movement of the UE within the RNA follows the cell selection and reselection method.

[0057] NR-light devices are introduced in R17. NR-light devices mainly have three scenarios:

[0058] Industrial Wireless Sensors: Compared with URLLC, this industrial wireless sensor has relatively low latency and reliability requirements. At the same time, the cost and power consumption of this device are also lower than URLLC and eMBB.

[0059] Video surveillance: Mainly used in video surveillance of smart cities, industrial factories, etc. Data collection and processing in smart cities facilitate more effective monitoring and control of urban resources and provide more effective services to urban residents.

[0060] Wearables: including smart watches, rings, electronic health devices, and some medical monitoring devices. One common feature of these devices is their small size.

[0061] The common requirements of the above three scenarios are as follows: Equipment cost: Compared with R15 / 16eMBB, lower equipment cost and complexity are required; the basic consensus is to reduce bandwidth and receive antennas; Equipment size: relatively small equipment size; Coverage: The coverage is required to be equivalent to R15 / 16eMBB. If coverage loss is caused by reducing receive antennas, reducing bandwidth, reducing power level or other measures to reduce UE complexity, compensation is required.

[0062] For the above three scenarios, different scenarios will correspond to different requirements, such as:

[0063] Industrial wireless sensors: 99.99% reliability; end-to-end latency 100ms; Bit rate requirement 2Mbps; battery life of the device at rest is several years; for security-related sensors, latency requirement is 5-10ms.

[0064] Video Survaillance: Bit rate requirement is 2-4Mbps; latency requirement is <500ms; reliability requirement is 99.-99.9%; for some high-end videos, the rate is 2-4Mbps; the uplink traffic is relatively large.

[0065] Wearables: Refer to LTE Cat 4, with a rate of 150Mbps / 50Mbps.

[0066] It should be understood that the terms "system" and "network" are often used interchangeably in this article. The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0067] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present application.

[0068] The present application embodiment provides an information reporting method, such as Figure 2 As shown, including:

[0069] Step 21: The terminal indicates relevant information of the terminal to the network device;

[0070] The relevant information of the terminal includes at least one of the following:

[0071] The capability level of the terminal, the type of the terminal, and the category of the terminal.

[0072] Accordingly, the present application also provides an information acquisition method, such as Figure 3 As shown, including:

[0073] Step 31: The network device receives the terminal related information indicated by the terminal;

[0074] Step 32: The network device schedules the terminal based on the terminal capability limitation determined by the relevant information of the terminal;

[0075] The relevant information of the terminal includes at least one of the following:

[0076] The capability level of the terminal, the type of the terminal, and the category of the terminal.

[0077] In this embodiment, the terminal may be an NR-terminal, or may be an NR-light terminal, which is not exhaustive here. The solution provided in this embodiment may be applicable to all types of terminals that can access the communication network, that is, all types of terminals may send relevant information of the corresponding terminal to the network device.

[0078] Furthermore, in this embodiment, the condition for executing step 21 may be that step 21 is executed before the terminal enters the connected state and the AS is securely activated; correspondingly, the network device may execute step 31 before the terminal enters the connected state and the AS is securely activated.

[0079] That is to say, the solution provided in this embodiment enables the terminal to report relevant information of the terminal to the network device before the terminal enters the connected state and the AS is securely activated, so that the network device can predict the capability limitation of the terminal based on the relevant information of the terminal before receiving the capability information of the terminal, and identify whether the terminal is a low-capability terminal.

[0080] Based on the foregoing, the following describes in detail how a terminal indicates relevant information of the terminal in combination with multiple examples:

[0081] Example 1:

[0082] The terminal indicating relevant information of the terminal to the network device includes:

[0083] The terminal indicates the relevant information of the terminal to the network device through the first logical channel identifier (Logical Channel Identify, LCID) used by MSG3 in the four-step random access.

[0084] Correspondingly, the network device receives the relevant information of the terminal indicated by the terminal, including:

[0085] The network device receives MSG3 using the first LCID in the four-step random access sent by the terminal, and determines relevant information of the terminal.

[0086] That is, the terminal implicitly indicates the relevant information of the terminal through the first LCID of MSG3.

[0087] Among them, the one using LCID in MSG3 is the Common Control Channel (CCCH).

[0088] In addition, the terminal determines the first LCID corresponding to the relevant information of the terminal according to the first corresponding relationship;

[0089] Among them, the first corresponding relationship includes: the corresponding relationship between different preset LCIDs in at least one preset LCID and different preset related information; the first LCID is one of the at least one preset LCID; the first corresponding relationship is: preset, or configured by the network device.

[0090] Correspondingly, the network device determines the relevant information of the terminal corresponding to the first LCID according to the first corresponding relationship.

[0091] Specifically, the network device configures the first correspondence relationship, and the network device may carry the first correspondence relationship through system broadcast information and send it to the terminal. Alternatively, the network device may also carry the first correspondence relationship through MAC CE or RRC signaling and send it to the terminal. This is not exhaustive.

[0092] The method of presetting the first corresponding relationship may be: based on protocol regulations, the first corresponding relationship is preset on the network device and the terminal side.

[0093] Furthermore, before sending the relevant information, the terminal may first determine the LCID corresponding to the relevant information according to the first corresponding relationship, and use the LCID as the first LCID; then set the CCCH to the first LCID, and send it to the network device;

[0094] After receiving MSG3, the network device determines which type of relevant information reported by the terminal is according to the LCID used by CCCH and the first corresponding relationship.

[0095] For example, the terminal type is used as the terminal related information for explanation:

[0096] Different NR-light terminal types can be defined in advance in the first correspondence. The LCID used by MSG3 of the NR-light terminal type during cell access is different from the LCID used by other non-NR-light terminal types.

[0097] Furthermore, the LCID used by MSG3 during the cell access process for each NR-light terminal type varies according to the terminal type, and some NR-light terminal types may also use the same LCID.

[0098] Take the example that the first correspondence includes at least one terminal type, and different terminal types correspond to different LCIDs. For example, as shown in Table 1 below: The values ​​of a, b, and c are the LCID values ​​reserved by the current standard. The value of each LCID (the corresponding terminal type) can be fixed in the protocol or broadcast and configured in the system broadcast, that is, the first correspondence can be fixed in the protocol in advance and preset in the network device or terminal, or it can be configured for the terminal by the network device through the system broadcast.

[0099] Video surveillance terminal Terminal Category 1 LCID=a Wearable device terminal Terminal Category 2 LCID=b Industrial Sensor Type Terminal Terminal Category 3 LCID=c

[0100] Table 1

[0101] Furthermore, the value of the aforementioned LCID may be between 33 and 51 as reserved by the current protocol. The values ​​of LCID and their corresponding numbers may be shown in Table 2 below, that is, the values ​​of a, b, and c may be between 33 and 51. For example, terminal category 1 may correspond to LCID 33, terminal category 2 may correspond to LCID 41, and terminal category 3 may correspond to LCID 49. Of course, if more terminal categories or types or capability levels are divided, more values ​​from 33 to 51 may be set to correspond to different terminal types or categories or capability levels, which are not exhaustively listed here.

[0102]

[0103]

[0104] Table 2

[0105] In addition, the relevant information of the terminal is also used to characterize the capability limitation of the corresponding terminal.

[0106] The method further includes: the terminal acquires a second corresponding relationship; wherein the second corresponding relationship includes: a corresponding relationship between at least one preset related information and a capability limitation of the terminal; the second corresponding relationship is preset or configured by a network device. Similarly, the second corresponding relationship being preset can be understood as being specified in the protocol; the second corresponding relationship being configured by a network device can be understood as being configured by the network device for the terminal through system broadcast, or can be configured for the terminal through MAC CE or RRC signaling, which will not be repeated here.

[0107] The capability limitation includes at least one of the following: transport block size (TBS) limitation, bandwidth support limitation, reception (RX) support limitation, modulation and coding scheme (MCS) support limitation, transmission (TX) support limitation, processing delay limitation, and layer 2 (L2) cache (buffer) limitation.

[0108] Each terminal type represents a type of terminal capability or the capability level of the terminal. The capability level restrictions are fixed in the protocol or configured by system broadcast, including the following capability restrictions, such as TBS restriction, bandwidth support restriction, RX support restriction, MCS support restriction, TX support restriction, processing delay restriction, L2 buffer restriction, etc. For example, in conjunction with Table 3, the various capability restrictions corresponding to terminal categories 1, 2, and 3 may be partially the same or completely different.

[0109]

[0110] Table 3

[0111] Example 2:

[0112] The terminal indicating relevant information of the terminal to the network device includes:

[0113] The terminal indicates the relevant information of the terminal to the network device through the bit value in the spare bit of MSG3 in the four-step random access;

[0114] Among them, in the spare bit positions of MSG3, different bit values ​​correspond to relevant information of different terminals.

[0115] Correspondingly, the network device receives the relevant information of the terminal indicated by the terminal, including:

[0116] The network device receives MSG3 in the four-step random access sent by the terminal; based on the bit value in the spare bit of MSG3, determines the relevant information of the terminal;

[0117] Among them, in the spare bit positions of MSG3, different bit values ​​correspond to relevant information of different terminals.

[0118] Specifically, the length of the spare bit can be 1 bit. In this example, the two terminal types can be divided according to the value of 1 bit in the spare bit. For example, the NR-light terminal sets the spare bit in MSG3 to 1 to indicate that the terminal is an NR-light type terminal. If the spare bit in MSG3 is set to 0, it can be represented as other types of terminals.

[0119] Correspondingly, after the network device reads the bit value of the spare bit in the MSG3, it can determine the relevant information of the terminal corresponding to the bit value according to the preset correspondence, such as determining the type of the terminal; and then, when the network device schedules the terminal, it schedules it according to the terminal capability limitation of NR-light.

[0120] In this example, the capability limitation may be the same as that in the above-mentioned example 1, and will not be described in detail.

[0121] It should be noted here that the NR-light type terminal means that this type of terminal is a low-capability terminal or a terminal with some special applications.

[0122] Example 3:

[0123] The terminal indicating relevant information of the terminal to the network device includes:

[0124] The terminal indicates the relevant information of the terminal to the network device through the first indication information carried in MSG3 in the four-step random access.

[0125] Correspondingly, the network device receives the relevant information of the terminal indicated by the terminal, including:

[0126] The network device receives first indication information carried by the terminal in MSG3 in four-step random access; and determines relevant information of the terminal based on the first indication information.

[0127] It should be understood that, before the terminal sends the first indication information or before the network device receives the first indication information, the following may also be included:

[0128] The terminal receives second indication information sent by the network device;

[0129] The second indication information is used to indicate the size of MSG3 that can be used by the terminal when accessing the network.

[0130] Furthermore, the MSG3 is an RRC establishment request message; accordingly, the method also includes: if the terminal determines that the size of MSG3 that the terminal can use is a first size based on the second indication information, then at least one information element IE for indicating relevant information of the terminal is carried in the RRC establishment request message.

[0131] That is, when sending MSG3, if MSG3 is specifically an RRC establishment request message, then the size of MSG3 indicated in the second indication information can be determined, for example, it can be a 64 / 72-bit MSG3; if it is this size (that is, the first size), then it can be considered that at least one IE can be carried in MSG3, and the at least one IE is used to indicate the relevant information of the terminal. In other words, the at least one IE constitutes the first indication information.

[0132] The aforementioned second indication information may be explicit or implicit, specifically: when the second indication information is explicit, the size of MSG3 may be directly included in the second indication information. When the second indication information is implicit, some characteristic information or some attribute information may be included in the second indication information; accordingly, the terminal may determine whether the network device indicates that the size of MSG3 of the terminal is the first size based on the characteristic information or attribute information.

[0133] In addition, the size of MSG3 can be 64 / 72 bits, or 48 / 56 bits, or other sizes; the size of 64 / 72 bits is different from other sizes in the related art, and can be defined as the first size, and other sizes are the second size, which will not be enumerated here.

[0134] The second indication information may be sent to the terminal through system broadcast, that is, the network device broadcasts a second indication information through system broadcast, and the second indication information indicates that the resident terminal in the cell can use the size of 64 / 72bit MSG3 on the access network side, that is, a new RRCSetupRequest message (RRC setup request message) can carry one or several IEs. Alternatively, the second indication information indicates that the resident terminal in the cell can use the 72bit MSG3 size on the access network side, that is, a new RRCSetupRequest message, and the RRCSetupRequest message carries certain IEs, and the MSG3 size is 64 / 72bit.

[0135] The one or more IEs may be defined in the protocol. The one or more IEs constitute the first indication information, and the format or specific contents of the one or more IEs may be defined in the protocol.

[0136] One or more IEs carried by the above RRCSetupRequest message or the newly defined RRCSetupRequest message may be the first indication information, that is, used to indicate the terminal type or terminal category or terminal capability level and the like.

[0137] In this example, the correspondence between the relevant information of the terminal and the capability limitation of the terminal and the subsequent processing are the same as those in the previous example and will not be described in detail here.

[0138] It can be seen that by adopting the above scheme, the terminal can indicate the terminal's capability level or terminal type or terminal category to the network device in advance, so as to indicate the terminal's capability to the network side, so that the network side can reasonably schedule the terminal according to the terminal's capability limitations before obtaining the terminal's capability, so that different types of terminals can share the network.

[0139] The present application embodiment provides a terminal, such as Figure 4 As shown, including:

[0140] A first communication unit 41 indicates relevant information of the terminal to the network device;

[0141] The relevant information of the terminal includes at least one of the following:

[0142] The capability level of the terminal, the type of the terminal, and the category of the terminal.

[0143] Accordingly, the embodiment of the present application also provides a network device, such as Figure 5 As shown, including:

[0144] A second communication unit 51 receives the terminal related information indicated by the terminal;

[0145] A second processing unit 52 schedules the terminal based on the terminal capability limitation determined by the relevant information of the terminal;

[0146] The relevant information of the terminal includes at least one of the following:

[0147] The capability level of the terminal, the type of the terminal, and the category of the terminal.

[0148] In this embodiment, the terminal may be an NR terminal, or may be an NR-light terminal, which is not exhaustive here. The solution provided in this embodiment may be applicable to all types of terminals that can access the communication network, that is, all types of terminals may send relevant information of the corresponding terminal to the network device.

[0149] Furthermore, in this embodiment, before the terminal enters a connected state and before the AS is securely activated, the relevant information of the terminal can be indicated to the network device; correspondingly, the network device can receive the relevant information of the terminal indicated by the terminal before the terminal enters a connected state and before the AS is securely activated.

[0150] That is to say, the solution provided in this embodiment enables the terminal to report relevant information of the terminal to the network device before the terminal enters the connected state and the AS is securely activated, so that the network device can predict the capability limitation of the terminal based on the relevant information of the terminal before receiving the capability information of the terminal, and identify whether the terminal is a low-capability terminal.

[0151] Based on the foregoing, the following describes in detail how a terminal indicates relevant information of the terminal in combination with multiple examples:

[0152] Example 1:

[0153] The first communication unit 41 of the terminal indicates the relevant information of the terminal to the network device through the first LCID used by MSG3 in the four-step random access.

[0154] Correspondingly, the second communication unit 51 of the network device receives MSG3 using the first LCID in the four-step random access sent by the terminal, and determines the relevant information of the terminal.

[0155] In addition, the terminal further includes a first processing unit 42, which determines a first LCID corresponding to the relevant information of the terminal according to the first corresponding relationship;

[0156] Among them, the first corresponding relationship includes: the corresponding relationship between different preset LCIDs in at least one preset LCID and different preset related information; the first LCID is one of the at least one preset LCID; the first corresponding relationship is: preset, or configured by the network device.

[0157] Correspondingly, the second processing unit 52 of the network device determines the relevant information of the terminal corresponding to the first LCID according to the first corresponding relationship.

[0158] The method of presetting the first corresponding relationship may be: based on protocol regulations, the first corresponding relationship is preset on the network device and the terminal side.

[0159] The first communication unit 41 obtains a second corresponding relationship; wherein the second corresponding relationship includes: a corresponding relationship between at least one preset related information and a capability limitation of the terminal; the second corresponding relationship is preset or configured by a network device. Similarly, the second corresponding relationship being preset can be understood as being specified in the protocol; the second corresponding relationship being configured by a network device can be understood as being configured by the network device for the terminal through system broadcast, or can be configured for the terminal through MAC CE or RRC signaling, which will not be repeated here.

[0160] The capability limitation includes at least one of the following: transmission block size (TBS) limitation, bandwidth support limitation, reception (RX) support limitation, modulation and coding strategy (MCS) support limitation, transmission (TX) support limitation, processing delay limitation, and layer 2 (L2) cache (buffer) limitation.

[0161] Example 2:

[0162] The first communication unit 41 of the terminal indicates the relevant information of the terminal to the network device through the bit value in the spare bit of MSG3 in the four-step random access;

[0163] Among them, in the spare bit positions of MSG3, different bit values ​​correspond to relevant information of different terminals.

[0164] Correspondingly, the second communication unit 51 of the network device receives MSG3 in the four-step random access sent by the terminal; based on the bit value in the spare bit of MSG 3, determines the relevant information of the terminal;

[0165] Among them, in the spare bit positions of MSG3, different bit values ​​correspond to relevant information of different terminals.

[0166] Specifically, the length of the spare bit can be 1 bit. In this example, the two terminal types can be divided according to the value of 1 bit in the spare bit. For example, the NR-light terminal sets the spare bit in MSG3 to 1 to indicate that the terminal is an NR-light type terminal. If the spare bit in MSG3 is set to 0, it can be represented as other types of terminals.

[0167] In this example, the capability limitation may be the same as that in the above-mentioned example 1, and will not be described in detail.

[0168] Example 3:

[0169] The first communication unit 41 of the terminal indicates the relevant information of the terminal to the network device through the first indication information carried in MSG3 in the four-step random access.

[0170] Correspondingly, the second communication unit 51 of the network device receives the first indication information carried by the terminal in MSG3 in the four-step random access; and determines the relevant information of the terminal based on the first indication information.

[0171] It should be understood that, before the terminal sends the first indication information or before the network device receives the first indication information, the following may also be included:

[0172] The first communication unit 41 of the terminal receives second indication information sent by the network device;

[0173] The second indication information is used to indicate the size of MSG3 that can be used by the terminal when accessing the network.

[0174] Furthermore, the MSG3 is an RRC establishment request message; accordingly, the first processing unit 42 of the terminal, if it is determined based on the second indication information that the size of MSG3 that the terminal can use is the first size, carries at least one information element IE for indicating relevant information of the terminal in the RRC establishment request message.

[0175] The one or more IEs may be defined in the protocol. The one or more IEs constitute the first indication information, and the format or specific contents of the one or more IEs may be defined in the protocol.

[0176] In this example, the correspondence between the relevant information of the terminal and the capability limitation of the terminal and the subsequent processing are the same as those in the previous example and will not be described in detail here.

[0177] It can be seen that by adopting the above scheme, the terminal can indicate the terminal's capability level or terminal type or terminal category to the network device in advance, so as to indicate the terminal's capability to the network side, so that the network side can reasonably schedule the terminal according to the terminal's capability limitations before obtaining the terminal's capability, thereby allowing different types of terminals to share the network.
