Description

Technical Field

[0002] In the related art, the network-side device has the capability information of the user equipment (UE), but in some scenarios, the UE has the problem of temporary capability limitation. For example, for a multi-card terminal (MUSIM, Multi-Universal Subscriber Identity Module), that is, a terminal with more than one USIM card installed, each USIM card corresponds to a UE in the communication system. The hardware or radio frequency of a multi-card terminal is shared by multiple USIM cards in the terminal. When multiple USIM cards are in the Radio Resource Control (RRC) connection state for communication at the same time, there will be a capability change (hardware / radio frequency conflict) within the multi-card terminal, causing at least one USIM card to be in a temporarily limited capability state in the corresponding network.

[0033] The capability reporting method, apparatus, UE, network-side equipment, medium, and computer program product provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through some embodiments and their application scenarios.

[0034] The capability reporting method, apparatus, UE, network-side equipment, medium, and computer program product provided in the embodiments of the present application can be applied to scenarios where capability limitation information is reported when a UE removes capability limitations or updates capability limitations.

[0035] Currently, a Multi-Universal Subscriber Identity Module (MUSIM) terminal has temporary capability restrictions during actual operation.

[0036] Taking a dual-SIM terminal as an example, there are currently two solutions to support dual SIM cards in a simultaneous Radio Resource Control (RRC) connected state for signal transmission. One is to use two sets of hardware or radio frequency (RF), which is equivalent to combining two complete device motherboards and placing them in the same UE housing. This implementation can support the simultaneous operation of two USIM cards, but has disadvantages such as high cost, high power consumption, and large device size. Another solution is that the two SIM cards can share some of the terminal's hardware or radio frequency for signal transmission. This hardware or radio frequency can be switched within the dual-SIM network based on the actual needs of the two SIM cards. It is understandable that the latter solution requires the UE corresponding to one card to indicate to the corresponding network-side device whether the UE's capabilities are partially restricted or no longer restricted. For example, taking SIM card A and SIM card B as an example, when SIM card A is in a connected state and SIM card B is in a disconnected state, the terminal's capabilities are occupied by SIM card A, and SIM card A is in an unrestricted state in the corresponding network. If card B is about to establish or restore an RRC connection, part of the terminal's RF / hardware needs to be switched from card A to card B. At this time, the UE of card A needs to indicate a temporary partially limited capability state to the corresponding network. Otherwise, the network will configure or schedule the UE based on the UE capabilities saved on the network side or the UE capabilities reported by the UE in the UECapabilityInformation message, which will cause the UE to lose data from network A or waste resources of network A.

[0037] In this way, when the UE has a temporary capability limitation problem, the UE needs to indicate the temporary partial capability limitation information to the corresponding network side device. In the related technology, how the UE reports the capability limitation information to the network side device is a problem to be solved. Otherwise, there will be problems such as UE transmission abnormality or waste of network side device resources.

[0038] The embodiment of the present application provides a capability reporting method, apparatus, UE, network-side equipment, medium, and computer program product. The UE can report to the network-side equipment at least one of information indicating a service cell or service cell group that the UE expects to be released, the UE's capability limitation information, and information indicating a target cell where the UE has capability limitations when there is a capability limitation or a capability limitation update. This allows the UE to accurately indicate to the network-side equipment when there is a capability limitation or a capability limitation update, so that the network-side equipment can smoothly learn that the UE has capability limitations or capability limitation updates, thereby enabling the UE to report capability limitation information to the network-side equipment, thereby avoiding problems such as abnormal UE transmission or waste of network-side equipment resources.

[0039] Figure 2 A flow chart of a capability reporting method provided in an embodiment of the present application is shown as follows: Figure 2 As shown, the message sending method may include the following step 201.

[0040] Step 201: When the UE has capability limitation or capability limitation update, the UE sends at least one of the following to the network side device: first information, second information and third information.

[0041] Among them, the above-mentioned first information can be used to indicate the service cell or service cell group that the UE expects to be released; the above-mentioned second information may include the UE's capability limitation information; the above-mentioned third information can be used to indicate the target cell with capability limitation of the UE, and the target cell includes at least one of the following: at least one service cell, at least one service cell group, at least one candidate cell, and at least one candidate cell group.

[0042] In some embodiments of the present application, the UE may send at least one of the above-mentioned first information, second information and third information through the following messages: UE Assistance Information (UAI), RRC connection establishment completion message, RRC connection recovery completion message, RRC reconfiguration completion message, measurement report, UEInformationResponse.

[0043] In some embodiments of the present application, the serving cell or serving cell group that the UE expects to be released may be at least one serving cell or at least one serving cell group that the UE expects to be released due to limited capabilities, wherein the serving cell may be a secondary cell (SCell), a primary cell, or a primary-secondary cell. Taking the UE including card 1 and card 2 as an example, a radio frequency chain (RF chain) of the UE supports operating in frequency band A. The UE corresponding to card 1 will report that it supports band A during the UE capability reporting process. The network side device can configure serving cell 1 for the UE based on the service situation. The operating frequency of serving cell 1 is frequency X, which belongs to band A. The serving cell is represented by a serving cell identifier configured by the network side device, or a secondary cell identifier. When card 2 wants to use this RF chain, card 1 cannot be used. The UE of card 1 then sends UE assistance information (UE Assistance Information, UAI) to the network side device, indicating that it expects the network side device to release serving cell 1. Specifically, the UE can indicate the identification information of serving cell 1. After the network side device releases the configuration of serving cell 1, the RF chain can switch from card 1 to card 2.

[0044] In some embodiments of the present application, the capability limitation information of the UE includes at least one of the following: frequency information that the UE has capability limitations, and indication information that the UE temporarily does not support dual connectivity DC.

[0045] In some embodiments of the present application, the frequency information of the capability limitation may include but is not limited to: a frequency point, a frequency band, a frequency range, and a band combination.

[0046] In some embodiments of the present application, the frequency information of the UE's capability limitation may include but is not limited to: the frequency that the UE is prohibited from being configured, the frequency that the UE does not want to be configured, and the frequency that the UE has low capability. Among them, the frequency that the UE has low capability includes the MIMO capability or bandwidth capability reduction of the UE at the frequency. For example, taking the UE including card 1 and card 2 as an example, a radio frequency chain (RF chain) of the UE supports operating in frequency band A. The UE corresponding to card 1 will report that it supports band A during the UE capability reporting process. When card 2 wants to use this RF chain, card 1 cannot be used. Then the UE of card 1 sends UE assistance information (UE Assistance Information, UAI) to the network side device, indicating that band A is prohibited from being configured or is not expected to be configured as a service band.

[0047] In some embodiments of the present application, the above-mentioned target cell may be configured by a network-side device for the UE.

[0048] In some embodiments of the present application, when the UE has capability limitation or capability limitation update, the UE sends first information to the network side device; or, when the UE has capability limitation or capability limitation update, the UE sends second information to the network side device; or, when the UE has capability limitation or capability limitation update, the UE sends third information to the network side device; or, when the UE has capability limitation or capability limitation update, the UE sends first information and second information to the network side device; or, when the UE has capability limitation or capability limitation update, the UE sends first information and third information to the network side device; or, when the UE has capability limitation or capability limitation update, the UE sends second information and third information to the network side device; or, when the UE has capability limitation or capability limitation update, the UE sends first information, second information and third information to the network side device.

[0049] It should be noted that when there is a capability limitation and the network side allows reporting of capability limitation information, the UE sends at least one of the first information, the second information, and the third information to the network side device. When sending, the UE can decide to send one or more of the first information, the second information, and the third information. It is understandable that after the UE sends the first information, since the first information is related to the service cell in which the UE is currently working, the UE cannot immediately remove the capability, and the UE will start a wait timer. After the wait timer expires, the UE will automatically switch the relevant capabilities indicated in the first information to other USIM cards. If the UE receives a configuration release command from the network side device during the waiting timer, the UE can stop the waiting timer. After the UE sends the second information, since the second information is not related to the currently working configuration / resources, the UE does not need to start the waiting timer. As a UE implementation, after confirming that the second information has been successfully sent, the UE can switch the corresponding capabilities to other USIM cards.

[0050] In some embodiments of the present application, when the UE sends the first information to the network side device, the UE sends the second information to the network side device.

[0051] It is understandable that when the UE sends the first information to the network side device, it must send the second information.

[0052] It is understandable that if the UE only sends the first information to the network side device, when the network side releases the service cell or service cell group indicated in the first information, as a network implementation (implementation method 1), the network side will discard the first information, because the content indicated by the first information no longer has actual meaning. In this case, the network side does not have the stored UE capability restriction information, and when the UE has no capability restriction, the UE does not need to indicate to the network side that there is no capability restriction; as another network implementation (implementation method 2), the network side generates the second information based on the first information (or generates the actual capability restriction information of the UE). In this case, the network side has the stored UE capability restriction information, and when the UE has no capability restriction, the UE does not need to indicate to the network side that there is no capability restriction. It should be noted that, considering the possibility of different network side implementations, the UE can send the second information when sending the first information to ensure that the network side has the capability restriction information of the UE, and when the UE has no capability restriction, it indicates to the network side that there is no capability restriction.

[0053] In some embodiments of the present application, when the first information includes the cell identifier of the service cell that the UE expects to be released, the second information includes the frequency information of the service cell that the UE expects to be released, and the frequency information includes at least one of the following: frequency point, frequency band, and frequency range; or, when the first information includes indication information for indicating that the UE expects the secondary cell group SCG to be released, the second information includes indication information for indicating that the UE does not support DC.

[0054] In some embodiments of the present application, the capability reporting method provided in the embodiments of the present application may further include the following step 200.

[0055] Step 200: The UE receives first configuration information from a network-side device.

[0056] The first configuration information is used to indicate whether the UE should send the second information simultaneously with sending the first information.

[0057] In some embodiments of the present application, if the network device supports implementation mode 2, the network device may send first configuration information to the UE, indicating that the UE does not need to send the second information when sending the first information. In this way, the UE's reporting can be reduced, saving signaling overhead. Optionally, after receiving the first configuration information, if the UE has reported capability restriction information, when the UE has no capability restriction, the UE needs to report that there is no capability restriction.

[0058] In some embodiments of the present application, step 200 may be performed before step 201. In some embodiments of the present application, if the UE only sends the second information to the network-side device, the UE may send the first information to the network-side device, or may not send the first information to the network-side device. This is not specifically limited in the embodiments of the present application.

[0059] In some embodiments of the present application, the UE may first send the first information to the network side device, and then send the second information to the network side device; or it may send the first information and the second information to the network side device at the same time. The embodiments of the present application are not specifically limited. In this way, the UE can, based on the first configuration information, indicate to the network side device that the UE has no capability restrictions when the UE no longer has capability restrictions. Since the network side device has received the capability information related to the configuration information expected to be released sent by the UE, it can confirm that the capability information is configurable after receiving the UE's indication of no capability restrictions, so that the network side device can smoothly learn about the UE's removal of capability restrictions or capability restriction updates, thereby improving the effect of the network side device updating the terminal's restricted capabilities. In some embodiments of the present application, the capability reporting method provided in the embodiments of the present application may also include the following steps 202 or 203.

[0060] Step 202: After the UE has sent the fourth information to the network-side device and the UE no longer has capability restrictions, the UE sends the first indication information to the network-side device.

[0061] Step 203: When the UE has sent the first information to the network side device but has not sent the second information and the third information, and the UE no longer has capability restrictions, the UE does not send the first indication information to the network side device.

[0062] The fourth information includes at least one of the following: the second information, the third information; the first indication information is used to indicate that the UE has no capability restriction.

[0063] It can be understood that, when the UE has sent the second information to the network side device and the UE no longer has capability restrictions, the UE sends the first indication information to the network side device; or, when the UE has sent the third information to the network side device and the UE no longer has capability restrictions, the UE sends the first indication information to the network side device; or, when the UE has sent the second information and the third information to the network side device and the UE no longer has capability restrictions, the UE sends the first indication information to the network side device.

[0064] In some embodiments of the present application, after receiving the first indication information sent by the UE, the network side device can confirm whether the second information and / or third information stored on the network side is still valid, that is, whether the UE still has the capability limitations indicated in the second information and / or third information.

[0065] In some embodiments of the present application, after receiving the UAI sent by the UE, the network-side device can release the configuration of the corresponding SCell based on the SCell indicated in the UAI. It can be understood that since the SCell indicated in the UAI has been released, the network-side device will directly discard the UAI. If the network-side device reconfigures a secondary cell after a period of time, and the secondary cell UE still does not support it, the UE needs to re-report the UAI to request the release of the corresponding resources; if the configuration sent by the network-side device does not exceed the capability of the UE, the UE can directly apply the configuration to work normally. That is to say, when the UE has sent the first information to the network-side device, but has not sent the second information and the third information, and the UE no longer has capability restrictions, the UE does not send the first indication information to the network-side device. Optionally, the network can configure the UE whether to not send the first indication information to the network-side device when the UE has sent the first information to the network-side device, but has not sent the second information and the third information, and the UE no longer has capability restrictions.

[0066] In some embodiments of the present application, the UE may indicate to the network side device that there is no capability restriction by sending a MUSIM UAI that does not carry specific capability restriction information to the network side device.

[0067] The capability reporting method provided in the embodiment of the present application can, when there is capability limitation or capability limitation update, report to the network side device at least one of the information for indicating the service cell or service cell group that the UE expects to be released, the UE's capability limitation information, and the information of the target cell for indicating that the UE has capability limitation, so that when there is capability limitation or capability limitation update, the UE can accurately indicate to the network side device, so that the network side device can smoothly know that the UE has capability limitation or capability limitation update, so that the UE can report the capability limitation information to the network side device, avoiding problems such as abnormal UE transmission or waste of network side device resources.

[0068] In some embodiments of the present application, the above-mentioned third information may include at least one of the following: preference information of at least one service cell being set as a candidate cell; preference information of at least one candidate cell being set as a service cell; preference information of at least one service cell group being set as a candidate service cell group; and preference information of at least one candidate cell group being set as a service cell group.

[0069] In some embodiments of the present application, the above preference information may indicate the operation that the UE expects or does not expect the network side device to perform. For example, when there is a capability restriction on a serving cell, the network side device may be instructed that the serving cell is expected to be set as a candidate cell. If the network side sets the serving cell as a candidate cell, and the capability restriction information of the UE changes at a certain moment, and there is still a capability restriction on the candidate cell, the UE indicates that it does not expect the candidate cell to be set as a serving cell.

[0070] In some embodiments of the present application, the network-side device may configure at least one of a candidate cell and a candidate cell group for the UE, so that the UE may report capability limitation information corresponding to the candidate cell.

[0071] In some embodiments of the present application, when the UE has capability limitations or the UE has capability limitation updates on candidate configurations, the UE can indicate to the network side device that the UE has capability limitations on the candidate configurations through third information.

[0072] In this way, the UE can report the capability limitation through the serving cell configured by the network side device, thereby improving the flexibility of the UE in reporting the capability limitation and ensuring that the network side device can smoothly know when the UE removes or updates the capability limitation.

[0073] In some embodiments of the present application, after "UE sends third information to the network side device" in the above step 201, the capability reporting method provided in the embodiment of the present application may further include the following step 204 or step 205.

[0074] Step 204: The UE receives second indication information from the network side device.

[0075] The second indication information may be used to indicate at least one of the following: the UE sets at least one serving cell as a candidate cell, and the UE sets at least one serving cell group as a candidate cell group.

[0076] Step 205: The UE receives third indication information from the network side device.

[0077] The third indication information may be used to indicate at least one of the following: the UE sets at least one candidate cell as a serving cell, and the UE sets at least one candidate cell group as a serving cell group.

[0078] In some embodiments of the present application, the second indication information may be used to instruct the UE to set the currently applied serving cell or serving cell group as a candidate configuration. That is, after receiving the second indication information, if the capability corresponding to the currently applied serving cell or serving cell group is limited, the UE may not release the first configuration, but may set the first configuration as a candidate configuration to indicate that the first configuration is unavailable to the UE.

[0079] It can be understood that the UE setting the currently applied service cell or service cell group configuration as a candidate configuration can also be understood as the UE setting the currently applied service cell or service cell group configuration to a deactivated state or deconfigured or disabled to indicate that the currently applied service cell or service cell group configuration is not available to the UE.

[0080] In this way, since the UE can receive indication information from the network side device to set the currently applied serving cell and serving cell group as candidate cells or candidate cell groups, the UE can indicate to the network side device to remove the capability restriction through the candidate configuration configured by the network side device.

[0081] In some embodiments of the present application, when the UE removes capability restriction or updates capability restriction, the UE may receive third indication information from a network side device, and the third indication information may instruct the UE to apply the candidate cell or candidate cell group to restore the configuration of the restricted capability.

[0082] In some embodiments of the present application, after sending the third indication information to the UE, the network side device may also apply the candidate cell or candidate cell group to restore the configuration of the limited capability of the UE.

[0083] In this way, the UE can directly apply the candidate cell or candidate cell group to restore the configuration of the restricted capability based on the instructions of the network side device, so that the configuration of the restricted capability can be restored conveniently, and the network side device can smoothly learn that the UE has removed the capability restriction or updated the capability restriction, so that the UE can report the capability restriction information to the network side device, avoiding problems such as abnormal UE transmission or waste of network side device resources.

[0084] In some embodiments of the present application, the capability reporting method provided in the embodiments of the present application may further include the following step 206.

[0085] Step 206: The UE receives second configuration information from the network-side device, where the second configuration information is used to configure at least one of the following: at least one candidate cell and at least one candidate cell group.

[0086] In some embodiments of the present application, the network side device may instruct the UE to restore the configuration of the restricted capability by configuring at least one of the at least one candidate cell and the at least one candidate cell group through the second configuration information.

[0087] In this way, the network side device can instruct the UE through the second configuration information that it can configure at least one of the at least one candidate cell and at least one candidate cell group, thereby avoiding problems such as abnormal UE transmission or waste of network side device resources.

[0088] The capability reporting method provided in the embodiments of the present application is described below in conjunction with specific embodiments.

[0089] In some embodiments of the present application, the capability reporting method provided by the embodiments of the present application may include the following embodiment 1, embodiment 2, embodiment 3, embodiment 4 and embodiment 5.

[0090] Embodiment 1: defining the execution conditions of the UAI removal operation.

[0091] Taking the example that the UE includes card A and card B, and the UE's card B initiates an RRC connection, so that the UE's card A cannot work in band A, and the band A is configured as SCell 1, the message sending method provided in the embodiment of the present application may include the following steps S11 to S16.

[0092] Step S11: The UE reports the first UAI to the network-side device, requesting to release SCell 1.

[0093] Step S12: The UE determines whether to indicate to the network device that band A where SCell 1 is located is a forbidden band.

[0094] Step S12: The network-side device receives the first UAI sent by the UE, confirms that band A of the UE cannot be configured, and releases the configuration of band A.

[0095] Step S13: The network-side device sends an RRC reconfiguration message to the UE based on the first UAI.

[0096] Step S14: The UE receives the RRC reconfiguration message sent by the network-side device, and releases SCell1 based on the RRC reconfiguration message.

[0097] Step S15: When the service of card B is terminated and card A has no capability restriction, if the UE does not report band A as a prohibited frequency band in step S12, the UE does not need to report the second UAI; if the UE reports band A as a prohibited frequency band in step S12, the UE reports the second UAI to the network side device.

[0098] In some embodiments of the present application, the second UAI may be a MUSIM UAI, which does not carry specific capability restriction information. In other words, the second UAI may be a null UAI.

[0099] Step S16: The network-side device receives the second UAI sent by the UE and confirms that band A of the UE can be configured.

[0100] Embodiment 2: Based on the control of the network-side device, when the UE requests to release the configuration of the SCell, the capability information of the SCell and the configuration information of the SCell must be provided.

[0101] Taking the example that the UE includes card A and card B, and the UE's card B initiates an RRC connection, so that the UE's card A cannot work in band A, and the band A is configured as SCell 1, the message sending method provided in the embodiment of the present application may include the following steps S21 to S28.

[0102] Step S21: The network-side device corresponding to the card A of the UE sends first configuration information to the UE.

[0103] Step S22: The UE receives first configuration information from the network-side device.

[0104] Step S23: The UE reports the first UAI to the network-side device, requests the release of SCell 1, and indicates that the band where SCell 1 is located is band A.

[0105] Step S24: The network-side device receives the first UAI sent by the UE, and confirms that band A of the UE cannot be configured.

[0106] Step S25: The network-side device sends an RRC reconfiguration message to the UE based on the first UAI.

[0107] Step S26: The UE receives the RRC reconfiguration message sent by the network-side device, and releases SCell1 based on the RRC reconfiguration message.

[0108] Step S27: When the service of card B is terminated and card A has no capability restriction, the UE reports the second UAI to the network side device.

[0109] In some embodiments of the present application, the second UAI may be a MUSIM UAI, which does not carry specific capability restriction information. In other words, the second UAI may be a null UAI.

[0110] Step S28: The network-side device receives the second UAI sent by the UE and confirms that band A of the UE can be configured.

[0111] Embodiment 3: The UE indicates to the network side device that the UE has no capability restriction through the candidate cell configured by the network side device.

[0112] Taking the UE including card A and card B as an example, the message sending method provided in the embodiment of the present application may include the following steps S31 to S38.

[0113] Step S31: The network-side device sends second configuration information to the UE, where the second configuration information includes information related to candidate serving cells.

[0114] Step S32: The UE obtains second configuration information.

[0115] Step S33: The UE reports the first UAI to the network-side device based on the second configuration information, requesting to release the current partial configuration.

[0116] For example, it is assumed that the network-side device configures serving cell 1, serving cell 2, and serving cell 3 for card A of the UE, and the UE requests to release serving cell 1 and serving cell 2.

[0117] Step S34: The network-side device receives the first UAI sent by the UE and releases the corresponding configuration.

[0118] Step S35: The network-side device sends an RRC reconfiguration message to the UE based on the first UAI.

[0119] Step S36: The UE receives the RRC reconfiguration message sent by the network side device, and releases the corresponding configuration based on the RRC reconfiguration message.

[0120] Step S37: When there is no capability restriction or capability restriction update, the UE reports a second UAI to the network side device through at least one item of the candidate cell information to indicate to the network side device that the UE has no capability restriction or capability restriction update.

[0121] For example, consider a case where a UE requests the network device to release serving cell 1 and serving cell 2, and band 1 is configured as serving cell 1 and band 2 as serving cell 2. Therefore, "UE capability restriction is not limited" may indicate that the UE can operate on both band 1 and band 2 again. "UE capability restriction update" may indicate that band 1 is no longer limited while band 2 remains limited, or that band 2 is no longer limited while band 1 remains limited.

[0122] As can be understood, for example, if band 1 is no longer restricted but band 2 is still restricted, the UE can report at least one of the following candidate cell information: serving cell index 2, candidate frequency information corresponding to the actually released serving cell 2, and the cell index value of the candidate cell corresponding to the actually released serving cell 2. In this way, the UE can indicate to the network device that band 2 is still restricted and remove the capability restriction on band 1.

[0123] It should be noted that when the UE needs to remove all capability restrictions, it can report an empty UAI that does not include capability restriction information to the network side device. For example, if the network side device releases service cell 1 and service cell 2, and the terminal removes the capability restriction information of service cell 1 and service cell 2, the terminal can report a UAI to the network side device, wherein the UAI does not contain any of the index values of service cell 1 and service cell 2, frequency information, or cell index values in their corresponding candidate cells. At this time, after receiving the UAI, although the network side device has released the relevant configurations of service cell 1 and service cell 2, it can determine which specific restriction configuration information has been removed by comparing the relevant information of the candidate cells.

[0124] Step S38: The UE receives the RRC reconfiguration message sent by the network-side device and restores the corresponding restricted capability configuration.

[0125] Exemplarily, the UE may receive an RRC reconfiguration message sent by the network-side device, and the serving cell 1 that is no longer restricted may continue to be configured as the serving cell.

[0126] Embodiment 4: Setting a configuration with limited capabilities as a candidate configuration.

[0127] Taking the UE including card A and card B, the network side device configures service cell 1, service cell 2 and service cell 3 for the UE, and the UE requests to release service cell 1 and service cell 2 as an example, the message sending method provided in the embodiment of the present application may include the following steps S41 to S45.

[0128] Step S41: The UE reports third information to the network-side device, requesting that serving cell 1 and serving cell 2 be set as candidate cells.

[0129] Step S42: The UE receives second indication information sent by the network side device, where the second indication information is used to instruct the UE to change serving cell 1 and serving cell 2 into candidate cells.

[0130] It is understandable that after receiving the second indication information, the UE may not release the configuration of serving cell 1 and serving cell 2, but may set the configuration information to a candidate configuration or a deactivated state to indicate that the configuration information is unavailable to the UE.

[0131] It is understandable that the network side device will not release the configuration of serving cell 1 and serving cell 2, but will set the configuration information of serving cell 1 and serving cell 2 to a deactivated state or candidate configuration.

[0132] Step S43: When there is no capability restriction or capability restriction update, the UE reports first indication information to the network side device to indicate to the network side device that the UE has no capability restriction or capability restriction update.

[0133] Step S44: The network side device may send third indication information to the UE, where the third indication information is used to instruct the UE to set candidate cells 1 and 2 as serving cells.

[0134] Step S45: The UE receives the third indication information and sets candidate cells 1 and 2 as serving cells.

[0135] For example, after step S42, assuming that candidate cell 1 is no longer restricted but candidate cell 2 is still restricted, the UE may report third information to the network device, indicating that candidate cell 2 is restricted. The network device then knows that candidate cell 2 cannot be restored as a serving cell, but candidate cell 1 can be restored as a serving cell.

[0136] Embodiment 5: The UE release restricted capability configuration is not interpreted as corresponding capability restriction.

[0137] Taking the UE including card A and card B, the network side device configures service cell 1, service cell 2 and service cell 3 for the UE, and the UE requests to release service cell 1 and service cell 2 as an example, the message sending method provided in the embodiment of the present application may include the following steps S51 to S56.

[0138] Step S51: The UE reports a first UAI to the network-side device, requesting to release serving cell 1 and serving cell 2.

[0139] Step S52: The network-side device receives the first UAI.

[0140] It should be noted that after the network device releases the configuration of serving cell 1 and serving cell 2, it does not consider the corresponding capabilities to be restricted. In other words, the network device will continue to configure serving cell 1 and serving cell 2 for the UE.

[0141] Step S53: The UE receives the first RRC reconfiguration message and releases the configuration of serving cell 1 and serving cell 2.

[0142] Step S54: The network-side device sends a second RRC reconfiguration message to the UE. The second RRC reconfiguration message reconfigures serving cell 1 and serving cell 2 for the UE.

[0143] Step S55: When the UE has removed the capability restriction of at least one of serving cell 1 and serving cell 2, the UE directly applies the configuration based on the second RRC reconfiguration message.

[0144] Step S56: If the UE does not remove the capability restriction of at least one of serving cell 1 and serving cell 2, the terminal triggers reporting of the first information or the third information.

[0145] In this way, when reporting configuration information that is expected to be released due to capability limitation to the network device, the UE can send capability information related to the configuration information to the network device; or, the UE can indicate to the network device that the UE has capability limitation on the candidate configuration; or, when at least one of the frequency information in the capability limitation state and the indication information that DC is not supported has been reported, the UE can indicate to the network device that there is no capability limitation. In this way, the UE can accurately indicate to the network device when removing capability limitation or updating capability limitation, so that the network device can smoothly learn about the situation that the UE removes capability limitation or updates capability limitation, thereby improving the effect of the network device in updating the terminal's limited capability. Figure 3 A flow chart of a capability reporting method provided in an embodiment of the present application is shown as follows: Figure 3 As shown, the capability reporting method may include the following step 301.

[0146] Step 301: A network-side device receives at least one of the following from a UE: first information, second information, and third information.

[0147] Among them, the first information is used to indicate the service cell or service cell group that the UE expects to be released; the second information includes the UE's capability limitation information; the third information is used to indicate the target cell where the UE has capability limitations, and the target cell includes at least one of the following: at least one service cell, at least one service cell group, at least one candidate cell, and at least one candidate cell group.

[0148] In some embodiments of the present application, the network side device may receive first information from the UE; or, the network side device may receive second information from the UE; or, the network side device may receive third information from the UE; or, the network side device may receive first information and second information from the UE; or, the network side device may receive first information and third information from the UE; or, the network side device may receive second information and third information from the UE; or, the network side device may receive first information, second information, and third information from the UE.

[0149] It should be noted that, for a detailed description of step 301, reference may be made to the relevant descriptions in steps 201 to 206. To avoid repetition, details will not be given here.

[0150] In the capability reporting method provided in the embodiments of the present application, a network device can receive information sent by a UE indicating a serving cell or serving cell group that is expected to be released due to capability limitations, and the UE's capability limitation information; or, the network device can receive information sent by the UE indicating that the UE has capability limitations in a candidate configuration; or, the network device can receive information sent by the UE indicating a target cell with capability limitations. This enables the UE to report capability limitation information to the network device, avoiding problems such as UE transmission anomalies or waste of network device resources.

[0151] In some embodiments of the present application, the capability reporting method provided in the embodiments of the present application may further include the following step 302.

[0152] Step 302: The network-side device receives first indication information from the UE, where the first indication information is used to indicate that the UE has no capability restriction.

[0153] In some embodiments of the present application, the capability reporting method provided in the embodiments of the present application may further include the following step 303.

[0154] Step 303: The network-side device sends first configuration information to the UE, where the first configuration information is used to indicate whether the UE should send the second information simultaneously with the first information.

[0155] In some embodiments of the present application, when the first information includes the cell identifier of the service cell that the UE expects to be released, the second information includes the frequency information of the service cell that the UE expects to be released, and the frequency information includes at least one of the following: frequency point, frequency band, and frequency range; or, when the first information includes indication information for indicating that the UE expects the SCG to be released, the second information includes indication information for indicating that the UE does not support DC.

[0156] In this way, the network side device can instruct the UE whether to send the second information at the same time when sending the first information, and report the restricted capabilities under the control of the network side device. Therefore, when the UE has capability limitations or capability limitation updates, the network side device can better understand the capability limitations or capability limitation updates of the UE, thereby improving the effect of the network side device in updating the terminal's restricted capabilities.

[0157] In some embodiments of the present application, the third information includes at least one of the following: preference information of at least one service cell being set as a candidate cell; preference information of at least one candidate cell being set as a service cell; preference information of at least one service cell group being set as a candidate service cell group; and preference information of at least one candidate cell group being set as a service cell group.

[0158] In this way, the UE can report the capability limitation through the serving cell configured by the network side device, thereby improving the flexibility of the UE in reporting the capability limitation and ensuring that the network side device can smoothly know when the UE removes or updates the capability limitation.

[0159] In some embodiments of the present application, after "the network-side device receives the third information from the UE" in the above step 301, the capability reporting method provided in the embodiment of the present application may further include the following step 304 or step 305.

[0160] Step 304: The network side device sends second indication information to the UE, where the second indication information is used to indicate at least one of the following: the UE sets at least one serving cell as a candidate cell, and the UE sets at least one serving cell group as a candidate cell group.

[0161] Step 305: The network side device sends third indication information to the UE, where the third indication information is used to indicate at least one of the following: the UE sets at least one candidate cell as a serving cell, and the UE sets at least one candidate cell group as a serving cell group.

[0162] In some embodiments of the present application, the capability reporting method provided in the embodiments of the present application may further include the following step 306.

[0163] Step 306: The network-side device sends second configuration information to the UE, where the second configuration information is used to configure at least one of the following: at least one candidate cell and at least one candidate cell group.

[0164] In this way, on the one hand, the UE can receive indication information from the network-side device to set the currently applied service cell and service cell group as candidate cells or candidate cell groups, so that the UE can indicate to the network-side device through the candidate configuration configured by the network-side device to remove the capability restriction. On the other hand, based on the indication of the network-side device, the UE can directly apply the configuration of the candidate cell or candidate cell group to restore the restricted capability, so that the configuration of the restricted capability can be restored conveniently, and the network-side device can smoothly learn about the UE's removal of capability restriction or capability restriction update. In this way, the UE can report capability restriction information to the network-side device, avoiding problems such as abnormal UE transmission or waste of network-side device resources.

[0165] Figure 4 A schematic diagram of an interaction process of a capability reporting method provided in an embodiment of the present application is shown. Figure 4 As shown, the capability reporting method may include the following steps 401 and 402.

[0166] Step 401: When a user equipment (UE) has capability limitation or capability limitation update, the UE sends at least one of the following to a network side device: first information, second information, and third information.

[0167] Among them, the first information is used to indicate the service cell or service cell group that the UE expects to be released; the second information includes the UE's capability limitation information; the third information is used to indicate the target cell where the UE has capability limitations, and the target cell includes at least one of the following: at least one service cell, at least one service cell group, at least one candidate cell, and at least one candidate cell group.

[0168] Step 402: The network-side device receives at least one of the following from the UE: first information, second information, and third information.

[0169] The capability reporting method provided in the embodiment of the present application can, when there is capability limitation or capability limitation update, report to the network side device at least one of the information for indicating the service cell or service cell group that the UE expects to be released, the UE's capability limitation information, and the information of the target cell for indicating that the UE has capability limitation, so that when there is capability limitation or capability limitation update, the UE can accurately indicate to the network side device, so that the network side device can smoothly know that the UE has capability limitation or capability limitation update, so that the UE can report the capability limitation information to the network side device, avoiding problems such as abnormal UE transmission or waste of network side device resources.

[0170] In some embodiments of the present application, the capability limitation information of the UE includes at least one of the following: frequency information of the UE having capability limitation, and indication information that the UE temporarily does not support dual connectivity DC.

[0171] In some embodiments of the present application, the capability reporting method provided in the embodiments of the present application may further include the following steps 403 and 404, or include the following steps 405 and 404.

[0172] Step 403: When the UE has sent the fourth information to the network-side device and the UE no longer has capability restrictions, the UE sends the first indication information to the network-side device.

[0173] Step 405: When the UE has sent the first information to the network side device but has not sent the second information and the third information, and the UE no longer has capability restrictions, the UE does not send the first indication information to the network side device.

[0174] Step 404: The network-side device receives first indication information from the UE.

[0175] The fourth information includes at least one of the following: the second information, the third information; the first indication information is used to indicate that the UE has no capability restriction.

[0176] In some embodiments of the present application, the capability reporting method provided in the embodiments of the present application may further include the following steps 406 and 407.

[0177] Step 406: The network-side device sends first configuration information to the UE, where the first configuration information is used to instruct the UE whether to send the second information simultaneously with the first information.

[0178] Step 407: The UE receives first configuration information from the network-side device.

[0179] In some embodiments of the present application, when the first information includes the cell identifier of the service cell that the UE expects to be released, the second information includes the frequency information of the service cell that the UE expects to be released, and the frequency information includes at least one of the following: frequency point, frequency band, and frequency range; or, when the first information includes indication information for indicating that the UE expects the secondary cell group SCG to be released, the second information includes indication information for indicating that the UE does not support DC.

[0180] In some embodiments of the present application, the third information includes at least one of the following: preference information of at least one service cell being set as a candidate cell; preference information of at least one candidate cell being set as a service cell; preference information of at least one service cell group being set as a candidate service cell group; and preference information of at least one candidate cell group being set as a service cell group.

[0181] In some embodiments of the present application, after "the network side device receives the third information from the UE" in the above step 402, the capability reporting method provided in the embodiment of the present application may also include the following steps 408 and 409, or may also include the following steps 410 and 411.

[0182] Step 408: The network side device sends second indication information to the UE, where the second indication information is used to indicate at least one of the following: the UE sets at least one serving cell as a candidate cell, and the UE sets at least one serving cell group as a candidate cell group.

[0183] Step 409: The UE receives second indication information from the network side device.

[0184] Step 410: The network-side device sends third indication information to the UE, where the third indication information is used to indicate at least one of the following: the UE sets at least one candidate cell as a serving cell, and the UE sets at least one candidate cell group as a serving cell group.

[0185] Step 411: The UE receives third indication information from the network side device.

[0186] In some embodiments of the present application, the capability reporting method provided in the embodiments of the present application may further include the following steps 412 and 413.

[0187] Step 412: The network-side device sends second configuration information to the UE, where the second configuration information is used to configure at least one of the following: at least one candidate cell and at least one candidate cell group.

[0188] Step 413: The UE receives second configuration information from the network-side device.

[0189] In this way, on the one hand, the UE can receive indication information from the network-side device to set the currently applied service cell and service cell group as candidate cells or candidate cell groups, so that the UE can indicate to the network-side device through the candidate configuration configured by the network-side device to remove the capability restriction. On the other hand, based on the indication of the network-side device, the UE can directly apply the configuration of the candidate cell or candidate cell group to restore the restricted capability, so that the configuration of the restricted capability can be restored conveniently, and the network-side device can smoothly learn about the UE's removal of capability restriction or capability restriction update. In this way, the UE can report capability restriction information to the network-side device, avoiding problems such as abnormal UE transmission or waste of network-side device resources.

[0190] Each of the above-mentioned method embodiments, or various possible implementation methods in each method embodiment, can be executed separately, or any two or more of them can be executed in combination with each other. The specific implementation can be determined according to actual usage requirements, and the embodiments of this application do not limit this.

[0191] The capability reporting method provided in the embodiment of the present application can be executed by a capability reporting device. In the embodiment of the present application, the capability reporting device provided in the embodiment of the present application is described by taking the capability reporting method executed by the capability reporting device as an example.

[0192] The embodiment of the present application provides a capability reporting device 50, such as Figure 5 As shown, the capability reporting device 50 includes: a first sending module 51.

[0193] Among them, the first sending module 51 is used to send at least one of the following items to the network side device when the UE has capability limitation or capability limitation update: first information, second information and third information; wherein, the first information is used to indicate the service cell or service cell group that the UE expects to be released; the second information includes the UE's capability limitation information; the third information is used to indicate the target cell where the UE has capability limitation, and the target cell includes at least one of the following items: at least one service cell, at least one service cell group, at least one candidate cell, and at least one candidate cell group.

[0194] In a possible implementation, the capability limitation information of the UE includes at least one of the following: frequency information of the UE having capability limitation, and indication information that the UE temporarily does not support dual connectivity DC.

[0195] In a possible implementation, the first sending module 51 is further configured to send the first indication information to the network side device when the UE has sent the fourth information to the network side device and the UE no longer has capability restrictions;

[0196] or,

[0197] The first sending module 51 is further configured to not send the first indication information to the network side device if the UE has sent the first information to the network side device but has not sent the second information and the third information, and the UE no longer has capability restrictions;

[0198] The fourth information includes at least one of the following: the second information, the third information; the first indication information is used to indicate that the UE has no capability restriction.

[0199] In a possible implementation, the first sending module 51 is further configured to send second information to the network-side device when the UE sends the first information to the network-side device.

[0200] In a possible implementation, the apparatus further includes: a first receiving module;

[0201] The first receiving module is configured to receive first configuration information from a network-side device, where the first configuration information is used to indicate whether the UE should send the second information simultaneously with the first information.
