[0038] Figure 2 A schematic diagram of a network architecture 200 according to an embodiment of this application is illustrated. This network architecture 200 describes the network architecture of a 5G NR / LTE / LTE-A system, which can also be referred to as a 5G system (5GS) / evolved packet system (EPS) network architecture. The network architecture 200 includes at least one of the following: network device 110, terminal device 120, 5G core network (5GC) / evolved packet core (EPC) 210, home subscriber server (HSS) / unified data management (UDM) 220, and Internet service 230.

[0040] Figure 3A and Figure 3B The following are schematic diagrams of the wireless protocol stack structure of one embodiment of this application. Figure 3A and Figure 3B This introduction uses the 5G wireless protocol stack as an example. The 5G wireless protocol stack is divided into two planes: the user plane (UP) protocol stack and the control plane (CP) protocol stack. The user plane protocol stack contains the protocol suite used for user data transmission, while the control plane protocol stack contains the protocol suite used for control signaling transmission in the 5G system. The specific names of each protocol stack layer are as follows: like Figure 3AAs shown, the user plane protocol stack, from top to bottom, includes: the Service Data Adaptation Protocol (SDAP) layer, the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, the Medium Access Control (MAC) layer, and the Physical (PHY) layer.

[0041] like Figure 3B As shown, the control plane protocol stack, from top to bottom, includes: non-access stratum (NAS); radio resource control (RRC) layer, PDCP layer, RLC layer, MAC layer, and PHY layer.

[0042] It should be understood that the different layers in the above protocol stack have different functions, and they work together through inter-layer interaction to achieve communication between terminal devices and network devices. With the development of artificial intelligence technology, AI-assisted computing has permeated the processing implementation methods of the above protocol stack. For example, the scheduling algorithm of the MAC layer and the encoding / decoding algorithm of the PHY layer can apply artificial intelligence algorithms to improve the performance of communication algorithms.

[0043] As an example, Figure 3A and Figure 3B The wireless protocol architecture in this application is applicable to the wireless protocol architecture in this application. First node .

[0044] As an example, Figure 3A and Figure 3B The wireless protocol architecture in this application is applicable to the wireless protocol architecture in this application. Second node .

[0045] It should be understood that the interpretation of the terminology in the embodiments of this application may refer to the TS36, TS37 and TS38 series of specifications of the 3rd generation partnership project (3GPP), but may also refer to the specifications of the Institute of Electrical and Electronics Engineers (IEEE).

[0046] Terminal device capability reporting In cellular mobile communication, terminal devices can report their own capability information (i.e., UE capability information) to the network, and the network side stores the terminal device capability information in the core network elements. Afterwards, the terminal device establishes a connection with the base station, which requests the UE capability information from the core network. Once the base station obtains the UE capability information, it configures the transmission parameters of various radio interfaces for the terminal device based on its capabilities.

[0047] Figure 4 This is an example diagram illustrating the process of UE capability information reporting.

[0048] like Figure 4 As shown, Figure 4 This may include steps S410 to S460.

[0049] Step S410: The terminal device and the access network device perform the RRC connection establishment process.

[0050] In step S420, the terminal device sends a NAS message to the core network device.

[0051] In step S430, the access network device and the core network device perform initial context establishment for the terminal device.

[0052] In step S430, if the core network device stores the capability information of the terminal device, the capability information can be sent to the access network device during the initial context establishment process.

[0053] In step S440, the access network device sends a UE capability request message to the terminal device to request UE capability information. Step S440 can occur when the core network device does not provide UE capabilities to the access network device.

[0054] In step S450, in response to the UE capability information request message, the terminal device reports the UE capabilities.

[0055] Step S460: The access network device determines the air interface parameters (or wireless parameters, wireless transmission parameters, etc.) of the terminal device based on the received UE capabilities.

[0056] In step S470, the access network equipment and the terminal equipment perform RRC reconfiguration to configure the air interface parameters of the terminal equipment.

[0057] In some technologies, segmentation mechanisms are introduced for capability messages of terminal devices. Because communication systems have introduced many features in different versions, and early terminal devices lacked these features, these features were included as part of the terminal device's capabilities. As communication systems have evolved, the size of terminal device capability messages has increased significantly, exceeding the maximum processing capacity of the access layer's encryption / decryption modules. Segmentation mechanisms can solve this problem. For example... Figure 4The message carrying UE capabilities in step S450 may be quite large. In this case, the UE capabilities in step S450 can be sent in segments.

[0058] After the core network stores the terminal device's capability information, if the terminal device is replaced (e.g., changing phones with the same SIM card), the terminal device can initiate a capability update process to update the capability information stored in the core network. Alternatively, the terminal device may update its capabilities due to temporary limitations. For example, if the terminal device overheats or has low power, it may request a temporary reduction in air interface configuration parameters from the base station via "UE assistant information (UAI)". (Continue to refer to...) Figure 4 ,like Figure 4 As shown in step S480, the terminal device can send UE assistance information to request a temporary reduction in air interface configuration parameters. Since this is a temporary situation, once these temporary conditions are lifted, the access network device can configure the air interface parameters according to the original terminal device capabilities. Therefore, this temporary restriction will not be notified to the core network.

[0059] The UE capability reporting process in related technologies suffers from at least the following problems: 1) The message size for reporting UE capabilities is too large; 2) The capability information reported by the terminal device depends entirely on the network device's requirements and does not consider the terminal device's service needs; 3) Notifying the network device via UAI messages may require a large number of messages, leading to heavy signaling load when the terminal device's capabilities change frequently. To better understand problem 3), the following example illustrates the process of terminal device temperature changes. When the terminal device overheats, it notifies the network device via a UAI message. After the temperature drops, it needs to notify the network device again via a UAI message. Therefore, this process requires at least two UAI messages. When the terminal device's temperature changes frequently, the number of UAI messages that need to be transmitted is even larger, resulting in a heavy signaling load.

[0060] This application proposes an improvement scheme to address the aforementioned issues regarding the reporting of UE capabilities. Figure 5 This is a schematic flowchart of a wireless communication method provided in an embodiment of this application.

[0061] Figure 5 The method shown can be performed by a terminal device and a network device. The network device may, for example, include a first access network device. The first access network device may be the access network device corresponding to the current serving cell of the terminal device.

[0062] Figure 5 The method shown may include step S510.

[0063] In step S510, the terminal device sends first capability information to the first access network device. The first capability information can be used to indicate one or more capabilities of the terminal device.

[0064] In some embodiments, the capabilities indicated by the first capability information may belong to the UE capability types in the first set. As one implementation, the UE capability types in the first set include all UE capability types contained in the communication protocol used by the terminal device. That is, the first set can be understood as the complete set of UE capability types.

[0065] The UE capability types in the first set can satisfy one or more of the following: specified by a protocol, indicated by a network device (e.g., a first access network device), or pre-configured in the terminal device by the operator. For example, the network device can send first information. The first information can be used to indicate some or all of the UE capability types in the first set. Exemplarily, the first information can be carried in a broadcast message and / or dedicated signaling. Exemplarily, the first information can be carried in one or more of the following messages: RRC message, underlying message (such as a MAC layer control message), and application layer message.

[0066] In some embodiments, the first set may include one or more dimensions. Each dimension may include one or more UE capability types. For example, the first set may include one or more of the following dimensions: number of MIMO layers, maximum number of aggregated carriers, maximum number of cell groups, maximum transmit power, frequency band, frequency band combination, list of supported AI models, and supported AI model training time. Taking the number of MIMO layers as an example, the UE capability types included in the first set in the MIMO layer dimension may include: 2, 4, 8, 16, 32, etc.

[0067] In some embodiments, the first set may include one or more types of combined dimensions. The combined dimension may be a combination of multiple dimensions. For example, at least two of the following dimensions may be bundled into a combined dimension: number of MIMO layers, maximum number of aggregated carriers, maximum number of cell groups, maximum transmit power, frequency band, frequency band combination, list of supported AI models, and supported AI model training time. Taking the number of MIMO layers and the maximum number of aggregated carriers as the first combined dimension as an example, the UE capability types included in the first set of the first combined dimension may include: a maximum number of aggregated carriers of 2, 3, 4, 5, 6, etc. when the number of MIMO layers is 2; a maximum number of aggregated carriers of 2, 3, 4, 5, etc. when the number of MIMO layers is 4; a maximum number of aggregated carriers of 2, 3, 4, 5, etc. when the number of MIMO layers is 16; and a maximum number of aggregated carriers of 2, 3, 4, etc. when the number of MIMO layers is 32.

[0068] In some embodiments, the capabilities indicated by the first capability information may belong to some or all dimensions in the first set, or the capabilities indicated by the first capability information may belong to a combination of some or all dimensions in the first set. For example, the terminal device may select some or all UE capability types from the first set and report them using the first capability information. Alternatively, the terminal device may select a combination of some or all dimensions from the first set and report them using the first capability information.

[0069] Based on this, the dimensions corresponding to the capabilities reported by the terminal device can be more flexible, resulting in a smaller message size for reporting UE capabilities and reducing the communication burden of the UE capability reporting process. In addition, compared with segmented transmission of UE capabilities, the process of this application is simpler, that is, it can simplify the UE capability reporting process.

[0070] In some embodiments, the first capability information indicates one or more capabilities, including a first capability. The first capability can be any one of the one or more capabilities indicated by the first capability information.

[0071] As one implementation method, the first capability can be less than or equal to the hardware capability of the terminal device. In other words, the terminal device can choose to report capabilities without exceeding its current hardware capabilities. For example, if the terminal device hardware supports 2, 3, or 4 aggregated carriers, the terminal device can report to the network device that it supports 2 aggregated carriers. In this case, the network device will configure the terminal device with 2 aggregated carriers according to the received capability, and will not configure 3 carriers for aggregation.

[0072] As one implementation approach, the first capability may include the capabilities that the terminal device expects to report. The capabilities that the terminal device expects to report can be the capabilities that the terminal device itself most desires to report. The capabilities that the terminal device expects to report may be limited by the capabilities corresponding to the terminal device's hardware, i.e., less than or equal to the capabilities corresponding to the terminal device's hardware. For example, if the terminal device's hardware supports a maximum of 5 carrier aggregations, the first capability could indicate that the terminal device supports 4 carrier aggregations. The fact that the terminal device supports 4 carrier aggregations could be a capability that the terminal device expects to report.

[0073] As one implementation approach, the first capability can be determined based on the service requirements of the terminal device. These service requirements can include one or more of the following: uplink transmission rate, downlink transmission rate, uplink transmission latency, downlink transmission latency, and service type. For example, if the terminal device's hardware supports four carrier aggregation, but the current data transmission rate required by the terminal device's service is low, then the first capability reported by the terminal device could be "supports two carrier aggregations".

[0074] As one implementation approach, the first capability can be determined based on the remaining battery power of the terminal device. For example, when the remaining battery power of the terminal device is greater than or equal to a first threshold, the first capability can be equal to or close to the capability corresponding to the terminal device's hardware. Conversely, when the remaining battery power of the terminal device is less than or equal to the first threshold, the first capability can be less than the capability corresponding to the hardware or close to the minimum capability. For instance, if the terminal device's radio frequency supports four carrier aggregation, but only has 20% battery power remaining, the first capability reported by the terminal device can be "supports two carrier aggregation," guiding the network device to configure fewer aggregated carriers for the terminal device to save power consumption.

[0075] It should be noted that while related technologies can also use UAI messages to report changes in terminal device capabilities, these messages must include the reason for the change. For example, a UAI message might indicate, "It is currently recommended to reduce to 2-carrier aggregation because the terminal device has low battery." This application, however, does not require notification of the reason for the change in terminal device capabilities, thus making it applicable to changes in terminal device capabilities caused by any reason.

[0076] In some embodiments, a first capability may belong to a first capability dimension. A first set may include one or more candidate options (or code points) for the first capability dimension. A first capability may be one of one or more candidate options. A candidate option can be understood as the type of UE capability that the terminal device can select to report within the first capability dimension. For example, if the first capability dimension is the number of MIMO layers, candidate options may include 2, 4, 8, 16, 32, etc. If the first capability dimension is the maximum number of aggregated carriers, candidate options may include 2, 3, 4, 5, 6, etc. For each capability dimension in the first set, the terminal device can obtain the corresponding candidate option.

[0077] Understandably, terminal devices can only select candidate options for reporting and cannot select UE capability types other than candidate options. Taking the number of aggregated carriers as the first capability dimension as an example, if the candidate options for the first capability dimension include 2, 4, 6, and 8, then the first capability can only be a value among 2, 4, 6, and 8. For example, if the terminal device's hardware supports a maximum of 5 carrier aggregations, but 5 is not among the candidate options, then the first capability reported by the terminal device can be 4 or 2.

[0078] By selecting one candidate as the primary capability for reporting, the number of bits required for the parameter indicating the primary capability can be reduced. For example, if there are two candidates, the parameter indicating the primary capability will require only 1 bit. However, if the parameter directly indicates the value of the primary capability, its number of bits will likely be greater than 1.

[0079] In some embodiments, the first capability can be one of one or more candidates in the first capability dimension that is closest to the capability to be reported (e.g., the closest one). The capability to be reported can satisfy one or more of the following: the capability to be reported is less than or equal to the capability corresponding to the hardware of the terminal device; the capability to be reported includes the capability that the terminal device expects to report; the capability to be reported can be determined based on the service requirements of the terminal device; the capability to be reported can be determined based on the remaining battery power of the terminal device.

[0080] For example, the first capability dimension is the bandwidth of the terminal device. The bandwidth value of the terminal device in the protocol is enumerated, and the enumerated values ​​(i.e., candidate options) are "100, 200, 300, 400, 500 (MHz)". If the terminal device actually supports a bandwidth of 320MHz, then the terminal device can choose 300MHz, which is closest to 320MHz, as the first capability to report.

[0081] For example, the first capability dimension is the number of aggregated carriers. Candidates for this first capability dimension include 2, 4, 6, and 8, while the terminal device's hardware supports a maximum of 5 carrier aggregations. The first capability reported by the terminal device can be 4, which is closest to 5. In this example, there are 4 candidates for the first capability dimension, and the first capability can be indicated by 2 bits for one of these candidates. However, if the value of the first capability is directly indicated, such as 5, at least 3 bits are required, which is more than the number of bits required by the candidate-based scheme.

[0082] For example, the first capability dimension is the number of aggregated carriers. Candidates for the first capability dimension include 2, 4, 6, and 8. Although the terminal device's hardware supports a maximum of 5 carrier aggregations, if the terminal device expects to report 3 aggregated carriers, then the first capability reported by the terminal device can be either 2 or 4, which is closest to 3. Whether to report 2 or 4 can be determined based on the terminal device's remaining battery power. For example, if the remaining battery power is 20%, the first capability can be 2. Similarly, if the remaining battery power is 90%, the first capability can be 4.

[0083] In some embodiments, the candidate may satisfy one or more of the following: indicated by a network device (e.g., a first access network device), predefined, preset by an operator, or specified by a protocol.

[0084] In some embodiments, the terminal device may send second capability information. The first access network device may receive the second capability information. The second capability information indicates one or more capabilities of the terminal device that differ from one or more capabilities of the terminal device indicated by the first capability information.

[0085] For example, the dimension of the capability indicated by the second capability information differs from the dimension of the capability indicated by the first capability information. For instance, the first capability information does not indicate the number of aggregated carriers supported by the terminal device; the second capability information indicates the number of aggregated carriers supported by the terminal device.

[0086] For example, for the same dimension, the capability indicated by the second capability information differs from the capability indicated by the first capability information. For instance, for the same dimension, the value of the capability indicated by the second capability information can be less than the value of the capability indicated by the first capability information, meaning the capability in that dimension is weaker. In other words, some or all of the capabilities of the terminal device indicated by the second capability information can be lower than some or all of the capabilities of the terminal device indicated by the first capability information. Alternatively, for the same dimension, the value of the capability indicated by the second capability information can be greater than the value of the capability indicated by the first capability information, meaning the capability in that dimension is stronger. In other words, some or all of the capabilities of the terminal device indicated by the second capability information can be higher than some or all of the capabilities of the terminal device indicated by the first capability information. For instance, for the first dimension, the value of the capability indicated by the second capability information can be greater than the value of the capability indicated by the first capability information; for the second dimension, the value of the capability indicated by the second capability information can be less than the value of the capability indicated by the first capability information. In other words, compared to the capabilities of the terminal device indicated by the first capability information, the capabilities of the terminal device indicated by the second capability information may be stronger in some dimensions and weaker in others.

[0087] The capabilities indicated by the first capability information can be understood as the capabilities of the old UE or the original UE, while the capabilities indicated by the second capability information can be understood as the capabilities of the new UE. That is, through the second capability information, the terminal device can dynamically update its capabilities to the network. Therefore, the second capability information can also be called updated capability information.

[0088] It is understood that through this application, dynamic capabilities can be reported to network devices at different times, in different scenarios, or for different needs, thereby guiding network devices to dynamically configure wireless parameters for terminal devices and thus improving communication performance.

[0089] In some embodiments, the first capability information may be the capability information initially reported by the terminal device to the network device. Based on the second capability information, the capabilities of the terminal device can be updated to the network device. In some embodiments, the first capability information may be the capability information updated by the terminal device in the previous step (i.e., capability information different from the initially reported capability), and based on the second capability information, the capabilities of the terminal device can be updated to the network device again, thus enabling multiple updates to the terminal device's capabilities.

[0090] It should be noted that the process of sending and determining the second capability information can be similar to that of the first capability information. For example, replacing the first capability information in the above embodiment with the second capability information can achieve the reporting of the second capability information. Exemplarily, one or more capabilities indicated by the second capability information belong to the UE capability types in the first set. To save space, the reporting of the second capability information will not be described in detail here.

[0091] In some embodiments, the capability information (including first capability information and / or second capability information) sent by the terminal device may include a first tag. The first tag can be used to indicate the transmission order of the capability information. For example, the value of the first tag can be incremented by 1 each time capability information is sent. The larger the value of the first tag, the later the capability information is transmitted. For multiple capability information, the transmission order of the multiple capability information can be determined based on the first tag. For example, if the terminal device sends two different capability information in two previous reports, and the time interval between the two reports is close, the network device may receive the later-sent capability information first, and then receive the earlier-sent capability information. Using the above method, the first tag value of the later-sent capability information is greater than the first tag value of the earlier-sent capability information. Based on the value of the first tag, the network device can determine the reporting order of the capability information, thereby avoiding incorrectly determining the transmission order based on the receiving order.

[0092] Network devices can update the capabilities of their stored terminal devices based on the order in which capability information is sent. Therefore, network devices typically need to determine their stored content based on the most recently sent capability information. As mentioned above, the first tag helps avoid incorrectly determining the sending order, thus enabling network devices to correctly update the capabilities of their stored terminal devices.

[0093] In some embodiments, after the value of the first tag is added to the first value, the value of the first tag can be cleared to zero. The first value can be the maximum value of the bits occupied by the first tag. For example, if the first tag occupies 3 bits, the first value can be 7. When the terminal device reports capability information for the first time, the value of the first tag can be 0; when it reports capability information for the second time, the value of the first tag can be 1; and so on, accumulating until the 8th report, when the value of the first tag can be 7; and when it reports for the 9th time, the value of the first tag can be 0 (i.e., cleared to zero), meaning the value of the first tag starts accumulating from 0 again.

[0094] It should be noted that this application does not limit the name of the first tag. For example, the first tag can also be called a value tag. In some embodiments, the second capability information can be sent proactively by the terminal device. In related technologies, the terminal device can only passively update the UE capability information. That is, the terminal device can only report its own capability information when the network device requests it to report capability information; if the network device does not request the terminal device to report capability information, the terminal device will not proactively report capability information. However, this application can enable the terminal device to proactively update its own capability information to the network side, which can increase the flexibility of the terminal device's capability information reporting. For example, if the capability reported by the terminal device through the first capability information is lower than the hardware capability, and if the terminal device's application layer wants to transmit a higher data rate, the terminal device can proactively notify the network side through the second capability information that it has higher hardware capabilities.

[0095] As one implementation method, the second capability information can be sent proactively by the terminal device based on its own state. That is, the terminal device can determine whether to proactively send the second capability information based on its own state. For example, the terminal device's state may include one or more of the following: the terminal device's battery level; the terminal device's transmission rate; the terminal device's temperature; the terminal device's folded or open state; and the terminal device's resources. Examples of each are provided below.

[0096] Taking the terminal device's battery level as an example, if the terminal device's battery is low and it wants the network device to use a more power-efficient configuration, even at the cost of sacrificing some service experience, the terminal device can send a second capability message to update its capabilities to a lower level. Conversely, if the terminal device is fully charged and wants the network device to use a higher configuration to improve the service experience, the terminal device can send a second capability message to update its capabilities to a higher level.

[0097] Taking the transmission rate of a terminal device as an example, if the original reported capability of the terminal device is lower than the hardware capability of the terminal device, and the terminal device wants to achieve a higher data transmission rate, it hopes that the first access network device will configure the air interface parameters according to the higher capability to transmit higher data rates. In this case, the terminal device can send second capability information to update the terminal device's capability to the higher capability.

[0098] Taking the temperature of a terminal device as an example, if the temperature of the terminal device is too high or too low, causing some hardware to malfunction and necessitating a reduction in the data transmission rate, the terminal device can send secondary capability information to update its capabilities to a lower level. If the temperature of the terminal device recovers from the excessively high or low level to its normal operating temperature, the terminal device can send secondary capability information to update its capabilities to a higher level.

[0099] The terminal device can be a foldable screen terminal device. The foldable screen terminal device can be in a folded state or an open state. The capabilities of the terminal device differ between its folded and open states. For example, the capabilities of a terminal device in a folded state are weaker than those in an open state. When the terminal device changes from a folded state to an open state or vice versa, it can send secondary capability information to update its capabilities to those corresponding to the current state.

[0100] Taking the resources of a terminal device as an example, the resources of a terminal device can include hardware resources and / or software resources. For example, a terminal device can add or remove external hardware resources and / or external software resources. External hardware resources can include, for example, one or more of the following: power banks, peripheral storage, external input / output devices, extended network cards, biometric devices, extended interfaces (e.g., USB, HDMI, etc.), in-vehicle communication devices, and handheld devices connected to the in-vehicle communication devices. External software resources can include, for example, one or more of the following: encryption software, authentication software, plugins, and software on the external hardware. For example, the terminal device of this application can include a handheld terminal device. After the handheld terminal device enters a car, the in-vehicle communication device can become the external hardware of the handheld terminal device, and the in-vehicle software can become the external software of the handheld terminal device. As another example, the terminal device of this application can include an in-vehicle communication device. After the handheld terminal device enters a car, the handheld terminal device can become the external hardware of the in-vehicle communication device, and the software of the handheld terminal device can become the external software of the in-vehicle communication device.

[0101] For example, if the terminal device adds external resources, it can send second capability information to update its capabilities to a higher level. Conversely, if the terminal device reduces external resources, it can send second capability information to update its capabilities to a lower level.

[0102] After receiving the second capability information, the network device can choose to have the first capability information enabled (or effective), the second capability information enabled, both the first and second capability information enabled, or the first capability information disabled. Enabling capability information can include: the first access network device being able to configure radio parameters based on the capability information; or, the first access network device needing to store the capability information normally. Disabling capability information can be the opposite of enabling it. For example, disabling capability information can include: the first access network device not configuring radio parameters based on the capability information, but only configuring radio parameters based on other enabled capability information; and / or, the first access network device no longer storing (i.e., deleting) the capability information.

[0103] In some embodiments, the first capability information and / or the second capability information may be permanently effective. Permanent effectiveness of capability information may include one or more of the following: the network device (e.g., the first access network device) can always configure radio parameters for the terminal device based on the capability information; the first access network device always stores the capability information during the period the terminal device accesses the first access network device; the core network device needs to store the capability information; and capability information without a limited effective time period. When capability information is permanently effective, the capability indicated by the capability information can be called a permanently effective capability. For example, if the capability reported by the terminal device in the first capability information is lower than its hardware capability, and the terminal device subsequently reports its own hardware capability through the second capability information, in this case, the second capability information may be permanently effective.

[0104] In some embodiments, the first capability information and / or the second capability information may be effective for a period of time. For example, the second capability information may be effective for a first time period. After the first time period, the second capability information may become invalid. When capability information is effective for a period of time, i.e., not permanently effective, the capability information may be called a UE temporary capability update indication, and the capability indicated by the capability information may also be called a temporary capability or a non-permanent capability. Temporary capabilities may not be reported to the core network equipment. Capabilities not reported to the core network equipment are mostly temporary capabilities. When the second capability information becomes invalid, the first capability information may become effective. Taking the second capability information being effective for a first time period as an example, the first capability information may become effective after the first time period. For example, after receiving the second capability information, the first access network equipment stores the original UE capability (i.e., the capability indicated by the first capability information) and the new UE capability (i.e., the capability indicated by the second capability information). From the time the second capability information is received, the first access network equipment considers the new UE capability to be effective for the first time period; after the effective period expires, the first access network equipment considers the original UE capability to be effective.

[0105] When capability information (including first capability information and / or second capability information) is effective for a period of time, the interaction of capability information between terminal devices and network devices can be reduced, thus lowering signaling load. Taking the temperature anomaly mentioned above as an example, when the terminal device's temperature is abnormal, the terminal device notifies the network device via a UAI message. When the terminal device's temperature returns to normal, the terminal device still needs to notify the network device via another UAI message. However, in this application, when the terminal device's temperature is abnormal, the terminal device can notify the network device to reduce its capability via the second capability information, and specify the effective period for the reduced capability. After the effective period for reducing the capability, the original capability can be restored without resending capability information. Therefore, capability updating and restoration can be achieved with a single message.

[0106] In some embodiments, the terminal device may send second information. The second information may be used to indicate whether the second capability information is permanently effective. Alternatively, the second information may be used to indicate whether the second capability information is effective for a period of time. The second information and the second capability information may be carried in the same message, in which case the second information may be used to indicate whether the capability of the terminal device transmitted in the same message is permanently effective or effective for a period of time.

[0107] In some embodiments, the start time of the first time period can be determined based on one or more of the following: the time when the second capability information is sent, or the time when the second capability information is received. For example, the start time of the first time period can be the time when the second capability information is sent or the time when the second capability information is received. That is, the second capability information can take effect immediately. Alternatively, the start time of the first time period can be a first specific duration after the time when the second capability information is sent, or the start time of the first time period can be a first specific duration after the time when the second capability information is received. In other words, the second capability information can take effect after a period of time following the transmission of the second capability information. The first specific duration can satisfy one or more of the following: predefined, indicated by the network device, or indicated by the terminal device.

[0108] In some embodiments, the terminal device may send first indication information. A network device (e.g., a first access network device) may receive the first indication information. The first indication information may be used to indicate information for a first time period. In other words, the terminal device may indicate information about the effective time period of second capability information. The first indication information and the second capability information may be carried in the same message.

[0109] As an example, the first indication information may indicate one or more of the following: the start time of the first time period, the end time of the first time period, and the duration of the first time period. The start time of the first time period and the end time of the first time period may be expressed in absolute time (e.g., including one or more of year, month, day, hour, minute, second, millisecond, etc.) or in the form of superframe number + system frame number. This representation allows terminal devices and network devices to have the same understanding of the start time or end time of the first time period.

[0110] For example, if a terminal device has an external power supply and sufficient power to actively undertake some AI model training tasks, it can notify the first access network device: "From the current moment, for the next 8 hours, the terminal device has the capability to train AI models." In other words, the second capability information indicates that the terminal device supports AI model training, and the first indication information indicates that the start time of the first time period is the current moment (the moment the second capability information is received), and the duration of the first time period is 8 hours. Based on the received information, the first access network device can request the terminal device to undertake a portion of the AI ​​model training tasks within 8 hours; after 8 hours, if no further capability reports (i.e., UE capability updates) are received from the terminal device, it can cease requesting the UE to undertake AI model training.

[0111] The following is combined Figure 6A and Figure 6B Please provide an explanation.

[0112] Figure 6A The method shown includes steps S611 and S612.

[0113] In step S611, the terminal device sends second capability information and first indication information. The second capability information indicates that the UE's temporary capability is updated. The first indication information indicates that the duration of the first time period is X, that is, the UE's temporary capability is effective within the duration X.

[0114] The start time for the UE's temporary capability to take effect can be the time when the second capability information is received. From that time, the first access network device can consider the UE's temporary capability to be effective for a period of X.

[0115] In step S612, after X time intervals following step S611, the first access network device considers the UE's temporary capability to be no longer valid.

[0116] Figure 6B The method shown includes steps S621 to S623.

[0117] In step S621, the terminal device sends second capability information and first indication information. The second capability information indicates that the UE's temporary capability is updated. The first indication information indicates that the UE's temporary capability is effective during a first time period from time T1 to time T2, i.e., during T1-T2.

[0118] Before T1, the UE's temporary capabilities are not active. During this period, the old UE capabilities can be active.

[0119] Step S622: At time T1, the first access network device considers that the UE's temporary capability has started to take effect.

[0120] In step S623, at time T2, the first access network device considers the UE's temporary capabilities to be no longer effective. The first access network device may consider the old UE capabilities to be effective.

[0121] In some embodiments, before the end of the first time period, the terminal device may send second indication information. This second indication information can be used to indicate that the second capability information is effective for a second time period. When indicating a second time period, the first time period may be invalid. In other words, within the first time period, the terminal device can modify the effective time period of the second capability information using the second indication information.

[0122] In some embodiments, the start time of the second time period can be determined based on one or more of the following: the time when the second indication information is sent; the time when the second indication information is received; and the end time of the first time period. For example, the start time of the second time period can be the time when the second indication information is sent, the time when the second indication information is received, or the end time of the first time period. That is, the second time period can start immediately at the current time or immediately after the end of the first time period. Alternatively, the start time of the second time period can be a second specific duration after the time when the second indication information is sent, or the start time of the second time period can be a second specific duration after the time when the second indication information is received. In other words, the second time period can start after a certain period of time after the transmission of the second indication information. The second specific duration can satisfy one or more of the following: predefined, indicated by the network device, or indicated by the terminal device.

[0123] In some embodiments, the duration of the second time period may satisfy one or more of the following: configured by the network device, predefined, or indicated by the terminal device.

[0124] In some embodiments, the second indication information can be used to indicate information about a second time period. In other words, the information about the second time period can be determined based on an indication from the terminal device. For example, the second indication information may include one or more of the following: the start time of the second time period, the end time of the second time period, and the duration of the second time period.

[0125] In some embodiments, the duration of the second time period can be equal to the duration of the first time period. In this case, the second indication information may not need to indicate the duration of the second time period, thereby reducing the information carried in the second indication information and reducing communication resource consumption. For example, if the start time of the second time period is the time when the second indication information is received, and the duration of the second time period is equal to the duration of the first time period, both being X, then the second indication information may only indicate "the second capability information continues to be effective," and the network device can assume that the second capability information continues to be effective for the same duration X. The following is in conjunction with... Figure 6C Please provide an explanation.

[0126] Figure 6C The method shown includes steps S631 and S632.

[0127] In step S631, the terminal device sends second capability information and first indication information. The second capability information indicates that the UE's temporary capability is updated. The first indication information indicates that the duration of the first time period is X, that is, the UE's temporary capability is effective within the duration X.

[0128] The start time for the UE's temporary capability to take effect can be the time when the second capability information is received. From that time, the first access network device can consider the UE's temporary capability to be effective for a period of X.

[0129] In step S632, before the end of the first time period, the terminal device sends a second indication message. The second indication message indicates that the new UE capability indicated by the second capability information remains effective. For a duration X starting from the moment the second indication message is received, the first access network device considers the second capability information to be effective.

[0130] In some embodiments, the duration of the second time period may not be equal to the duration of the first time period. In this case, the duration of the second time period can satisfy the following: the second indication information indicates, configured by the network device, and defined by the protocol. The following is in conjunction with... Figure 6D Please provide an explanation.

[0131] Figure 6D The method shown includes steps S641 and S642.

[0132] In step S641, the terminal device sends second capability information and first indication information. The second capability information indicates that the UE's temporary capability is updated. The first indication information indicates that the duration of the first time period is X, that is, the UE's temporary capability is effective within the duration X.

[0133] The start time for the UE's temporary capability to take effect can be the time when the second capability information is received. From that time, the first access network device can consider the UE's temporary capability to be effective for a period of X.

[0134] In step S642, before the end of the first time period, the terminal device sends a second indication message. The second indication message indicates that the new UE capability indicated by the second capability information remains effective, and indicates that the duration of the second time period is Y. For a duration Y starting from the moment the second indication message is received, the first access network device considers the second capability information to be effective.

[0135] It should be noted that the duration of the second capability information can be updated via the second instruction information. The total duration of the updated second capability information can increase or decrease. For example, the duration of the second time period indicated by the second instruction information can be greater than the remaining duration of the first time period, thus increasing the total duration of the second capability information. (Continue to refer to...) Figure 6D The end time of Y indicated by the second instruction information is later than the end time of the original effective duration X, thus extending the effective duration of the second capability information. For example, the duration of the second time period indicated by the second instruction information can be less than the remaining duration of the first time period, thereby reducing the total effective duration of the second capability information. The following explains... Figure 6E Please provide an explanation.

[0136] Figure 6E The method shown includes steps S651 and S652.

[0137] In step S651, the terminal device sends second capability information and first indication information. The second capability information indicates that the UE's temporary capability is updated. The first indication information indicates that the duration of the first time period is X, that is, the UE's temporary capability is effective within the duration X.

[0138] The start time for the UE's temporary capability to take effect can be the time when the second capability information is received. From that time, the first access network device can consider the UE's temporary capability to be effective for a period of X.

[0139] In step S652, before the end of the first time period, the terminal device sends a second indication message. The second indication message indicates that the new UE capability indicated by the second capability information remains effective, and indicates that the duration of the second time period is Y. For the duration Y starting from the moment the second indication message is received, the first access network device considers the second capability information to be effective. After Y ends, the first access network device considers the second capability information to be invalid, even if X has not yet ended.

[0140] from Figure 6E It can be seen that the end time of Y indicated by the second instruction information is earlier than the end time of the original effective duration X, that is, the effective time of the second capability information ends ahead of schedule.

[0141] It should be noted that in this application, the effective period of a certain capability information (e.g., a first time period, a second time period, etc.) may include one or more time periods. For example, if all capabilities indicated by the capability information are effective within the same time period, then the effective period may include one time period. Similarly, if different capabilities indicated by the capability information are effective within different time periods, then the effective period may include multiple time periods. Based on this, the start time of the effective period may include one or more times. The end time of the effective period may include one or more times. The duration of the effective period may include one or more durations.

[0142] In some embodiments, the capabilities included in the second capability information are those that have changed compared to the first capability information. That is, the capabilities indicated by the second capability information are different from those indicated by the first capability information. In other words, the terminal device only reports the capabilities that need updating (i.e., the changed capabilities) through the second capability information; capabilities that do not need updating do not need to be reported through the second capability information. For example, if the first capability information indicates "supports 4-layer MIMO and supports 2-cell carrier aggregation," and the updated capability is "supports 4-layer MIMO and supports 4-cell carrier aggregation," then the second capability information can indicate "supports 4-cell carrier aggregation."

[0143] In some embodiments, the second capability information may include capabilities that have not changed compared to the first capability information. That is, the capabilities indicated by the second capability information may be partially the same as those indicated by the first capability information. For example, if any capability of the terminal device needs to be updated and reported, other capabilities that do not need to be updated can also be indicated through the second capability information. For example, the second capability information may indicate all capabilities (e.g., all capabilities indicated by the first indication information or all capabilities of the terminal device stored by the network device). For instance, if the first capability information indicates "supports 4-layer MIMO and supports 2-cell carrier aggregation", and the updated capability is "supports 4-layer MIMO and supports 4-cell carrier aggregation", then the second capability information may indicate "supports 4-layer MIMO and supports 4-cell carrier aggregation".

[0144] In some embodiments, the second capability information may include third indication information. The third indication information can be used to indicate whether the second capability information and the first capability information are combined and effective. In other words, the third indication information can be used to indicate whether "the capability reported this time is combined with the previously reported capability." Alternatively, it can be said that the third indication information can be used to indicate whether the first capability information is invalid when the second capability information is effective. For example, if a terminal device reports the capability "can support carrier aggregation within Bands A and B" through the first capability information, and subsequently reports a new capability through the second capability information and the third indication information "Band C also supports carrier aggregation, and is combined with the previously reported capability," then the network device can understand that "the UE can support carrier aggregation within Bands A, B, and C."

[0145] In some embodiments, the terminal device may receive one or more configuration information. The configuration information may be sent by a first access network device. The configuration information may be used to configure the terminal device's radio parameters. One or more configuration information may correspond to one or more capability information. The one or more configuration information includes first configuration information. When the capability information corresponding to the first configuration information is in effect, the terminal device needs to execute the first configuration information.

[0146] For example, when the first access network device receives the second capability information and the second capability information becomes effective, the first access network device can reconfigure the wireless parameters of the terminal device using configuration information. For instance, in... Figure 6B At time T1, the first access network device can reconfigure the wireless parameters of the terminal device through configuration information, which corresponds to the second capability information.

[0147] For example, before the second capability information takes effect, the first access network device can configure the radio parameters after the second capability information takes effect through configuration information. In this case, the configuration information can also indicate that the configuration information corresponds to the second capability information, and / or, the configuration information can also indicate the effective time period of the configuration information (e.g., including one or more of the effective start time, effective end time, and effective duration). The configuration information takes effect during the effective time period of the second capability information corresponding to the configuration information. Continuing with... Figure 6B For example, in Figure 6B Before time T1, the first access network device may send configuration information and indicate that the configuration information will take effect at time T1, or indicate that the configuration information corresponds to the second capability information. The terminal device can then determine that the radio parameters of the configuration information will take effect from time T1 through this configuration information.

[0148] For example, at the point when the second capability information becomes invalid, the first capability information needs to become effective, and the first access network device can reconfigure the terminal device's wireless parameters through configuration information. For instance, in... Figure 6B At time T2, the first access network device needs to reconfigure the wireless parameters of the terminal device through configuration information, which corresponds to the first capability information.

[0149] In some embodiments, configuration information can be carried out via RRC messages.

[0150] In some embodiments, multiple configuration information items are carried in the same message. Alternatively, multiple configuration information items can be carried in multiple messages.

[0151] Carrying multiple configuration information through the same message can reduce the number of messages and can also notify the configuration information in advance before the effective time, so that the terminal device can prepare for reconfiguration in advance and reduce processing latency.

[0152] In some embodiments, the first access network device may send configuration information. This configuration information may correspond to capability information that is about to take effect or has already taken effect.

[0153] In some embodiments, the first access network device may also send corresponding information, which can be used to indicate capability information corresponding to one or more configuration information. During the effective time periods of different capability information, the terminal device can use the corresponding configuration information respectively.

[0154] It should be noted that this application does not limit the timing of the configuration information transmission. For example, the configuration information may be transmitted before or at the start of the corresponding capability information taking effect. In this case, the terminal device can begin executing the corresponding configuration information at the moment the capability information takes effect. Alternatively, the configuration information may be transmitted after the corresponding capability information takes effect. In this case, the terminal device can execute the corresponding configuration information immediately.

[0155] by Figure 6B Taking the scenario shown as an example, the first access network device can send two configuration messages to the terminal device, corresponding to different UE capabilities. The terminal device executes the first configuration message at time T1 and the second configuration message at time T2. The access network device can send these two configuration messages before or after time T1. If the terminal device receives the configuration message after time T1 and determines that time T1 has passed, it immediately executes the first configuration message. The two configuration messages can be notified to the terminal device through one RRC message or two RRC messages.

[0156] In some embodiments, in response to the terminal device executing the first configuration information, the terminal device may send response information. The response information may indicate that the terminal device's execution of the first configuration information was partially or fully successful. Partial success may mean that the terminal device can only execute a portion of the wireless parameters in the first configuration information, and cannot execute all the wireless parameters. Full success may mean that the terminal device executes all the wireless parameters in the first configuration information. For example, the terminal device needs to send response information after executing each piece of configuration information.

[0157] As mentioned above, multiple configuration information items are carried through a single message. In this case, multiple response information items corresponding to multiple configuration items need to be carried in multiple messages. Continuing with... Figure 6BFor example, if two configuration information messages are notified to the terminal device via a single RRC message, at or after time T1, after successfully executing the first configuration information message, the terminal device can send an RRC message carrying response information to the first access network device to indicate that the first configuration information message was successfully executed. For example, at or after time T2, after successfully executing the second configuration information message, the terminal device can send an RRC message carrying response information to the first access network device to indicate that the second configuration information message was successfully executed. For example, the response information can indicate that the execution of the first configuration information message was fully successful; the response information can indicate that the execution of the second configuration information message was partially successful; or, the response information can indicate that the execution of the first configuration information message was partially successful; or the response information can indicate that the execution of the second configuration information message was fully successful.

[0158] In some embodiments, the first access network device may send multiple configuration messages for the same capability information. Continuing with... Figure 6B For example, the first access network device can send the configuration information corresponding to the first capability information before time T1. It can then send the configuration information again before or after time T2. If multiple configuration messages correspond to the same capability information, the terminal device can execute based on the most recently received configuration information. In this case, it continues to execute based on... Figure 6B For example, if the first access network device determines to regenerate the configuration information for the first capability information before time T2, the first access network device can send the configuration information for the first capability information to the terminal device again. After receiving it, the terminal device discards the original configuration information and executes the new configuration information at time T2.

[0159] In some embodiments, when the serving cell of the terminal device changes, the terminal device does not execute one or more configuration information sent by the first access network device. In other words, when the serving cell of the terminal device changes, the terminal device no longer executes the configuration information sent by the access network device corresponding to the original serving cell that has not yet been executed.

[0160] In some embodiments, the serving cell change of the terminal device includes one or more of the following: the terminal device undergoes cell handover; the terminal device initiates RRC re-establishment, and the cell initiating the re-establishment is not the original serving cell; the terminal device performs an RRC recovery procedure in a non-original serving cell; the terminal device experiences radio link failure; the terminal device experiences beam failure, etc. Cell handover can include one or more of the following: normal handover, conditional handover, handover without RA, cross-system handover, intra-system handover, cross-carrier handover, intra-carrier handover, handover from a terrestrial cell to a non-terrestrial network (NTN) cell, and handover from an NTN cell to a terrestrial cell, etc.

[0161] Continue with Figure 6B For example, if the terminal device receives two sets of configuration information and executes them at times T1 and T2 respectively, but the terminal device undergoes cell handover between T1 and T2, then the terminal device will no longer execute the configuration information corresponding to time T2.

[0162] In some embodiments, the terminal device may send fourth indication information. The recipient of the fourth indication information may include a first access network device. The fourth indication information can be used to indicate whether the first capability information and / or the second capability information need to be sent to the core network device. In other words, the terminal device can decide whether the first access network device should send the received capability information to the core network device, and make corresponding indications through the fourth indication information. The first access network device can send the first capability information and / or the second capability information to the core network device according to the instruction of the fourth indication information.

[0163] For example, the terminal device can implicitly indicate whether to forward the first capability information and / or the second capability information to the core network device. Exemplarily, the fourth indication information can be used to indicate whether the first capability information and / or the second capability information are baseline capability information or hardware capability information. If they are baseline capability information or hardware capability information, the core network device needs to be notified; if they are not, the core network device does not need to be notified. If the terminal device wants the capability information currently reported to the first access network device to be notified to the core network device, it notifies the first access network device through the fourth indication information that "the currently reported terminal device capability information belongs to baseline capability information." Upon receiving this capability information, the first access network device then notifies the core network of the baseline capability information; otherwise, the base station does not notify the core network.

[0164] For example, if the terminal device expects the reported capability information to be valid for a relatively long period of time, such as 24 hours, the terminal device can notify the base station through the fourth indication information that "the currently reported terminal device capabilities need to be notified to the core network".

[0165] For example, if the capability information that the terminal device expects to report is only valid for a short period of time, such as 3 hours, the terminal device will notify the base station through the fourth indication information that "the terminal device capability currently reported does not need to be notified to the core network".

[0166] In some embodiments, whether to forward the first capability information and / or the second capability information to the core network device can satisfy the following: determined by the terminal device, determined by the first access network device, or specified by the protocol. For example, the protocol may stipulate that the first access network device notifies the core network device of all capability information after receiving it.

[0167] Figure 5 The method shown can also be performed by core network equipment. Figure 5The method shown may also include step S520. In step S520, the first access network device sends the third capability information to the core network device.

[0168] In some embodiments, the third capability information may be determined based on the first capability information and / or the second capability information. As one implementation, the third capability information may include one or more of the following: one or more capabilities indicated by the first capability information, and one or more capabilities indicated by the second capability information. For example, the third capability information may include some or all of the capabilities of the terminal device stored by the first access network device. The capabilities of the terminal device stored by the first access network device may include one or more of the following: currently active capabilities, future active capabilities, historically active capabilities, permanently active capabilities, and temporary capabilities.

[0169] For example, the third capability information may include the capabilities of terminal devices stored in the first access network device that are not stored in the core network device, i.e., the third capability information may indicate incremental capabilities.

[0170] For example, the third capability information may include all capabilities reported by the terminal device in this instance. For instance, after receiving the second capability information, the first access network device may send all capabilities indicated in the second capability information to the core network device via the third capability information.

[0171] For example, the third capability information may include all the capabilities of the terminal device stored by the first access network device, meaning that the third capability information can indicate all capabilities.

[0172] In some embodiments, if a first condition is met, the first access network device sends third capability information to the core network device. If the first condition is not met, the first access network device may not send the third capability information to the core network device. Therefore, it can be seen that the first access network device will only send the terminal device's capability information to the core network device under certain conditions.

[0173] In some embodiments, the first condition may be related to one or more of the following: the duration of the third capability information; whether the capability indicated by the third capability information is higher than the capability of the terminal device stored in the core network device; the indication of the terminal device; and the RRC status of the terminal device.

[0174] For example, the effective duration of the third capability information may include the effective duration of one or more capabilities indicated by the third capability information. The first condition may include, for example, that the effective duration of the third capability information is greater than or equal to a first duration threshold. The first duration threshold may satisfy one or more of the following: indicated by the terminal device; indicated by the core network device; or specified by the protocol.

[0175] For example, the terminal device notifies the first access network device that "the currently reported UE capabilities are valid for X hours, and will no longer be valid after X hours." The first access network device then determines whether to update the current UE capabilities to the core network device. The behavior of the first access network device can be: for UE capabilities with an effective duration of less than 1 hour, not to notify the core network; for UE capabilities with an effective duration of more than 1 hour, to notify the core network. That is, the first duration threshold is 1 hour.

[0176] For example, the first condition could include: the capability indicated by the third capability information is higher than the capabilities of terminal devices in the same dimension stored by the core network device. For instance, if the capability reported by the terminal device is higher than the UE capabilities in the same dimension stored by the core network, the core network device is notified to update the UE capability; otherwise, the core network is notified not to update the UE capability. In this approach, the core network device stores the highest capability reported by the terminal device. For example, if the terminal device previously reported "supports Layer 4 MIMO," and the first access network device has already reported this information to the core network device, if the terminal device reports "supports Layer 2 MIMO" again, the first access network device will not report this capability information to the core network device.

[0177] For example, the first condition may include: the terminal device indicates that the third capability information can be forwarded to the core network device. Exemplarily, the terminal device may use the fourth indication information described above to indicate whether the third capability information can be forwarded to the core network device.

[0178] For example, the first condition may include: the terminal device entering an idle state. For instance, if the terminal device enters an idle state during the period when the second capability information is effective, the first access network device can send the second capability information as third capability information to the core network device.

[0179] In some embodiments, when the first access network device sends third capability information to the core network device, the first access network device may also send fifth indication information to the core network device. The fifth indication information may be used to indicate a third time period, which may be the period during which the third capability information is effective. For example, if the third capability information includes second capability information, the fifth indication information may be used to indicate a first time period and / or a second time period.

[0180] As one implementation, the fifth instruction information may include one or more of the following: the total duration of the third time period, the remaining duration of the third time period, the start time of the third time period, and the end time of the third time period.

[0181] The following is based on Figure 7 Let's take an example to illustrate.

[0182] Figure 7The method shown includes steps S711 to S713.

[0183] In step S711, the terminal device sends second capability information and first indication information. The second capability information indicates that the UE's temporary capability needs to be updated. The first indication information indicates that the UE's temporary capability will be effective for a duration of X.

[0184] The start time for the UE's temporary capability to take effect can be the time when the second capability information is received. From that time, the first access network device can consider the UE's temporary capability to be effective for a period of X.

[0185] The first access network device decides to send the UE temporary capability to the core network device and calculates the remaining effective duration of the second capability information (i.e., the UE temporary capability) as X'.

[0186] In step S712, the first access network device sends the third capability information and the fifth indication information to the core network device. The third capability information indicates that the UE's temporary capability needs to be updated. The fifth indication information indicates that the UE's temporary capability will be effective within X'.

[0187] In step S713, after a time interval X following step S711, the first access network device considers the UE's temporary capability to be no longer valid. After a time interval X' following step S712, the core network device considers the UE's temporary capability to be no longer valid. In principle, the time interval X following step S711 and the time interval X' following step S712 are the same.

[0188] This application does not limit the timing at which the first access network device sends third capability information to the core network device. For example, in response to receiving first capability information and / or second capability information sent by the terminal device, the first access network device may send third capability information to the core network device. In other words, after receiving the dynamic capability report from the terminal device, the first access network device may immediately report the capability to the core network device. Alternatively, after receiving the first capability information and / or second capability information sent by the terminal device, the first access network device may send third capability information to the core network device after a first time interval. In other words, after receiving the dynamic capability report, the first access network device may wait a first time interval before reporting the capability to the core network device.

[0189] For example, after receiving the second capability information, the first access network device waits for a first period of time. If the second capability information is still effective after the first period of time has ended, the first access network device sends the capability indicated by the second capability information to the core network device through the third capability information.

[0190] The first duration can be represented, for example, by T_capabilitywindow. The first duration can satisfy one or more of the following: indicated by the terminal device; indicated by the core network device; specified by the protocol; or determined by the first access network device itself.

[0191] In some embodiments, after receiving the third capability information, the core network device can determine whether to store the third capability information. For example, the terminal device may not send the fourth indication information to the first access network device, that is, it may not notify whether to report the currently reported capability information to the core network device. In this case, after receiving the first capability message and / or second capability information reported by the terminal device, the first access network device will notify the core network of all received capabilities through the third capability information, and the core network will determine whether to store the capability itself.

[0192] It should be noted that before storing the third-party capability information, the core network device may have already stored the capabilities of the terminal device. The capabilities of the terminal device originally stored may be the same as or different from the capabilities indicated by the third-party capability information. If the core network device originally stored the capabilities of the terminal device, storing the third-party capability information can also be understood as the core network device updating its own stored capabilities.

[0193] This application does not limit whether the core network device deletes the capabilities originally stored in the core network device. For example, the core network device may delete the capabilities originally stored in the dimension corresponding to the capability indicated by the third capability information. Alternatively, the core network device may not delete the capabilities originally stored in the same dimension corresponding to the capability indicated by the third capability information. For example, the core network device may mark the originally stored capabilities as old capabilities and the newly stored capabilities as new capabilities. For example, the core network device may consider the originally stored capabilities and the newly stored capabilities to be combined and effective.

[0194] As mentioned above, third-party capability information can include incremental or full capabilities. The operation of core network equipment may differ depending on the specific circumstances.

[0195] For example, if the third-party capability information received by the core network equipment indicates an incremental capability, the core network equipment can update only the incremental part. For instance, if the core network stores the capability as "supports 4-layer MIMO, 4-cell carrier aggregation," and the newly received third-party capability information only indicates "supports 8-layer MIMO," then the core network updates the stored capability to "supports 8-layer MIMO, 4-cell carrier aggregation." If the newly received third-party capability information only indicates "supports 6-cell carrier aggregation," then the core network updates the stored capability to "supports 4-layer MIMO, 6-layer carrier aggregation." If the newly received capability information indicates that the UE's new capability is "supports 8-layer MIMO, 2-cell carrier aggregation," then the core network stores the new capability as "supports 8-layer MIMO, 4-cell carrier aggregation."

[0196] For example, if the third capability information received by the core network is all capabilities, the core network equipment can update all capabilities. For instance, if the core network stores the capability as "supports 4-layer MIMO, 4-cell carrier aggregation", and the newly received third capability information indicates that the terminal equipment's new capability is "supports 8-layer MIMO, 2-cell carrier aggregation", then the core network updates the stored capability to "supports 8-layer MIMO, 2-cell carrier aggregation".

[0197] In some embodiments, if a third condition is met, the core network device may store the third capability information sent by the first access network device. If the third condition is not met, the core network device may not store the third capability information sent by the first access network device. In other words, the core network device may store the third capability information sent by the first access network device under certain conditions.

[0198] In some embodiments, the third condition may be determined based on one or more of the following: whether the core network device has stored the capabilities of the terminal device; the effective duration of the third capability information; whether the capabilities indicated by the third capability information are higher than the capabilities of the terminal device stored by the core network device; the indication of the terminal device; and the RRC status of the terminal device.

[0199] For example, the third condition could include: the core network device has not stored the capabilities of the terminal device. For instance, after receiving the third capability information, the core network determines whether it has already stored the capabilities of the terminal device. If it has not stored them, it can store the third capability information; if it has stored the capabilities of the terminal device, it can choose not to store the third capability information.

[0200] For example, the third condition may include: the effective duration or remaining effective duration of the third capability information is greater than or equal to the second duration threshold. The second duration threshold may satisfy one or more of the following: determined by the core network device itself; indicated by the first access network device; or stipulated by the protocol. If the effective duration or remaining effective duration of the third capability information is less than the second duration threshold, the core network device can infer that the change in the terminal device's capabilities is due to the temporary addition of external resources, and therefore can decide not to store the third capability information. If the effective duration or remaining effective duration of the third capability information is greater than or equal to the second duration threshold, the core network device can infer that the third capability information will exist for a long time, and therefore can decide to store the third capability information.

[0201] For example, the third capability information indicates "the currently reported UE capability has a remaining effective duration of X'". The core network device can determine whether to store the UE capability based on the length of X'. For example, the core network device's behavior could be: not to store UE capabilities with a remaining effective duration of less than 1 hour; and to store UE capabilities with a remaining effective duration of more than 1 hour. That is, the second duration threshold is 1 hour.

[0202] For example, the third condition could include: the capability indicated by the third capability information is higher than the capability of the terminal device in the same dimension stored by the core network device. For instance, after receiving the third capability information, the core network determines whether it has already stored the capability of the terminal device. If it has already stored the capability information of the terminal device, it compares the newly received third capability information with the stored capability information. If the capability indicated by the newly received third capability information is higher, the newly received third capability information can be stored; if the previously stored capability information is higher, the newly received third capability information can be left unstored.

[0203] For example, the third condition may include: the terminal device indicates that the third capability information needs to be stored in the core network device.

[0204] For example, the third condition may include: the terminal device entering an idle state. For instance, if the terminal device enters an idle state during the period when the third capability information is effective, the core network device may store the third capability information.

[0205] In some embodiments, if a terminal device experiences a wireless link failure or other operation during the temporary capability's effective period, the first access network device can record the temporary capability and continue to use it after the terminal device's wireless link is restored.

[0206] In some embodiments, the first access network device may send fourth capability information and / or time information related to the fourth capability information to the second access network device. For example, the second access network device may include the access network device corresponding to the target cell of the terminal device. The fourth capability information may be determined based on the first capability information and / or the second capability information. For instance, the fourth capability information may include all capabilities indicated by the first and second capability information. For example, the fourth capability information may be used to indicate some or all of the capabilities of the terminal device stored by the first access network device. As one implementation, the fourth capability information may be used to indicate temporary capabilities of the terminal device stored by the first access network device.

[0207] The time information related to the fourth capability information can indicate the effective period of the fourth capability information. For example, the time information related to the fourth capability information may include one or more of the following: the start time of the effective period of the fourth capability information, the end time of the effective period of the fourth capability information, and the duration of the effective period of the fourth capability information.

[0208] Understandably, based on the fourth capability information, access network devices can exchange the capabilities of terminal devices. Therefore, the process of repeatedly exchanging capability information between terminal devices and second access network devices can be reduced, thereby reducing communication resource waste and saving terminal device energy consumption. Of course, if a terminal device deems it necessary to update its capabilities with the second access network device, it can also send updated capability information to the second access network device. The second access network device can then update its stored terminal device capabilities and their effective time periods based on this updated capability information.

[0209] In some embodiments, if the second condition is met, the first access network device may send fourth capability information and / or time information related to the fourth capability information to the second access network device. If the second condition is not met, the first access network device may not send the fourth capability information to the second access network device. In other words, the first access network device will only send the terminal device's capability information to the second access network device if certain conditions are met.

[0210] For example, the second condition includes one or more of the following: the terminal device switches to the cell corresponding to the second access network device; the terminal device initiates reconstruction for the cell corresponding to the second access network device; the terminal device executes the RRC recovery procedure for the cell corresponding to the second access network device; the second access network device requests the first access network device to send the terminal device's capabilities.

[0211] As one implementation, if the second capability information sent by the terminal device is valid for a period of time X, and the first access network device decides not to report the second capability information to the core network device, if the terminal device undergoes a handover within the period of time X, the first access network device can notify the second access network device (i.e., the target cell) of the second capability information, and the second access network device can determine the radio parameters of the terminal device according to the second capability information.

[0212] In some embodiments, the core network device may send fifth capability information to the second access network device.

[0213] The fifth capability information can be determined based on the first capability information and / or the second capability information. For example, the fifth capability information may include all the capabilities indicated by the first and second capability information. Exemplarily, the fifth capability information can be used to indicate some or all of the capabilities of the terminal device stored by the core network device. As one implementation, the fifth capability information can be used to indicate the temporary capabilities of the terminal device stored by the core network device.

[0214] Understandably, based on the fifth capability information, core network devices can send terminal device capabilities to second access network devices other than the first access network device. In this case, the second access network device does not need to request capability information from the terminal device, and the terminal device does not need to send capability information to the second access network device, thereby reducing communication resource waste and saving terminal device energy consumption. Of course, if the terminal device believes it needs to update its capabilities with the second access network device, it can also send updated capability information to the second access network device, and the second access network device can update its stored terminal device capabilities and effective time periods based on the updated capability information.

[0215] In some embodiments, if the fourth condition is met, the core network device may send the fifth capability information to the second access network device. If the fourth condition is not met, the core network device may not send the fifth capability information to the second access network device. In other words, the core network device may send the fifth capability information to the second access network device under certain conditions.

[0216] For example, the fourth condition may include one or more of the following: the terminal device switches to the cell corresponding to the second access network device; the terminal device initiates reconstruction for the cell corresponding to the second access network device; the terminal device executes the RRC recovery procedure for the cell corresponding to the second access network device; the capability indicated by the fifth capability information is effective or will be effective in the future (i.e., not currently invalid).

[0217] For example, if the core network device receives third capability information reported by the first access network device, and the first access network device indicates the effective period of the third capability information, the core network device can maintain the effective time information. If a terminal device undergoes handover or radio link reconstruction, and the second access network device requests the terminal device's capabilities (e.g., dynamic capabilities) from the core network, the core network device can provide the second access network device with one or more sets of capability information for the terminal device, as well as the time information of each capability (including one or more of the effective start time, effective duration, and effective end time). In this case, after obtaining the fifth capability information, the second access network device can directly apply the capability information obtained from the core network device and configure the corresponding radio parameters for the terminal device without needing to request capability information from the terminal device again.

[0218] The method embodiments of this application have been described in detail above. The apparatus embodiments of this application are described in detail below. It should be understood that the descriptions of the method embodiments correspond to the descriptions of the apparatus embodiments. Therefore, any parts not described in detail can be referred to the foregoing method embodiments.

[0219] Figure 8 This is a schematic structural diagram of a terminal device 800 provided in an embodiment of this application. The terminal device 800 may include a first transmitting unit 810.
