Description

Technical Field

[0001] The present application belongs to the field of wireless communication technology, and specifically relates to a UE capability change method, a terminal and a network side device. Background Art

[0002] Multi-card terminals can reside in multiple networks at the same time. There are many ways to implement multi-card terminals. Some multi-card terminals can send and receive on multiple networks at the same time without affecting each other. Some multi-card terminals, although they can reside on multiple networks at the same time, may reside on two networks in a time-division manner, that is, they reside on network A for a period of time to listen to the paging of network A, and reside on network B for a period of time to listen to the paging of network B. Or they connect to send and receive data on network A for a period of time, and receive paging on network B for a period of time. Or they receive data on network A for a period of time, and establish a connection or send and receive data on network B for a period of time. Some multi-card terminals that support dual-transmission and dual-reception can send and receive on multiple networks at the same time on a specific frequency band without affecting each other. On some other frequency bands, they may use time-division to send and receive data on two networks.

[0003] In specific applications, a multi-card terminal may need to transfer from network A to network B to perform tasks. For a multi-card terminal that supports multiple transmissions (Tx) or multiple receptions (Rx), while residing or maintaining a connection state on network A, it may be necessary to use some resources such as Tx or Rx channels to perform tasks on network B. However, the current capabilities or configurations of the terminal on network A may cause the user equipment (UE) to be unable to use some resources to meet its multi-card task requirements on network B. For this situation, there is a lack of corresponding solutions in the prior art. Summary of the invention

[0032] The following is a detailed description of the UE capability change method provided in the embodiment of the present application through some embodiments and their application scenarios in combination with the accompanying drawings.

[0033] Figure 2 A flow chart of a method for changing the capability of a UE in an embodiment of the present application is shown. The method 200 can be executed by a terminal. In other words, the method can be executed by software or hardware installed on the terminal. Figure 2 As shown, the method may include the following steps.

[0034] S210 , the UE determines that a capability change and / or configuration preference is required.

[0035] In an embodiment of the present application, a multi-card terminal may include multiple UEs, which are referred to as Multi-SIM UEs. It should be noted that a UE can be considered as a contracting entity. Multiple contracting entities can be configured on a terminal device. The contracting entity can be embodied by a subscriber identity module (Subscriber Identity Module, SIM) card. One SIM card corresponds to the contracting entity of one network. The SIM card stores the identifier of the contracting entity, that is, the identifier of the UE, such as the Subscription Permanent Identifier (SUPI), or the International Mobile Subscription Identity (IMSI). Therefore, when multiple SIM cards are inserted into a terminal or multiple electronic SIM card information is configured, the terminal and different contracting entities can constitute different UEs.

[0036] In an embodiment of the present application, a network-side device may initiate a capability transmission process to a UE in a connected state, thereby obtaining the wireless access capability information of the UE. For example, after receiving a UE capability query message (UECapabilityEnquiry), the UE sends a UE capability information message (UECapabilityInformation). During the communication process, the UE determines that a capability change and / or configuration preference is required. For example, for a multi-card terminal that supports multiple Tx or multiple Rx, the UE may need to utilize part of the Tx or Rx path to perform tasks on network B while residing or maintaining a connected state on network A. In order to meet this requirement, the UE determines that a capability change and / or configuration preference is required.

[0037] S212, the UE sends first request information, where the first request information is used to request a capability change and / or configuration preference from a network side device.

[0038] Optionally, the first request information may carry at least one of the following information (1) to (4).

[0039] (1) Configuration preference information. The configuration preference information is used to indicate the configuration desired by the UE. For example, the configuration preference information may include at least one of the following:

[0040] i. Configuration upper limit: that is, the UE expects the network configuration not to exceed the configuration preference.

[0041] ii. Time information of the configuration preference, wherein the time information includes one of the following: duration, cycle, start time, that is, the time when the UE expects the configuration preference to take effect.

[0042] iii. Periodic configuration switching request information. That is, the UE requests periodic configuration switching (Configuration Switching). For example, the network (NW) A sends two sets of configurations to the UE, and the UE switches the configurations in NW A according to the period.

[0043] iv. Multiple card configuration preference indication information, wherein the multiple card configuration preference indication information indicates that the configuration preference information is used for multiple cards. In other words, the configuration preference is used for multiple card purposes.

[0044] (2) Capability change requirement information: The capability change requirement information is used to indicate that the UE needs a capability change. The UE expects the network configuration to not exceed the changed capability.

[0045] (3) Reconfiguration indication information. The reconfiguration indication information is used to indicate that the network side device needs to reconfigure the UE, or the reconfiguration indication information is used to indicate that the network side device does not need to reconfigure the UE. For example, the reconfiguration indication information indicates that reconfiguration is required, that is, the configuration preference and / or capability change requirements may require the network to reconfigure the UE. For example, the current configuration has dual connectivity (MR-DC SCG), the UE capability is changed to not support dual connectivity, and the network is expected to release the SCG connection. The reconfiguration indication information indicates that reconfiguration is not required, that is, the configuration preference and / or capability change requirements may not require the network to reconfigure the UE. For example, dual connectivity (MR-DC SCG) is not configured in the current configuration, and the UE sends a first request message to expect the network not to configure dual connectivity. At this time, the network does not need to initiate reconfiguration of the corresponding first request message.

[0046] (4) Purpose indication information. The purpose indication information is used to indicate that the first request information is for a multi-card purpose requesting a capability change and / or configuration preference. That is, the UE sends the first request for a multi-card purpose, not for power saving or overheating, etc., and therefore expects the network side device to respond.

[0047] In a possible implementation of an embodiment of the present application, the first request message may be sent via a UE assistance information message. In the related art, for the purpose of saving power or preventing overheating, the UE may send a preference indication to the network in a UE assistance information message. The network decides whether to change the configuration of the UE. For example: the UE recommends that the network configure fewer carriers, fewer MIMO layers, or a longer DRX cycle. The network may adjust the configuration of the UE accordingly. Therefore, in an embodiment of the present application, the UE assistance information message may be multiplexed, and the first request message may be sent in the UE assistance information message to request capability changes and / or configuration preferences for multi-card purposes.

[0048] In another possible implementation, the first request message may also be sent via a UE capability information (UECapability Information) message. In related technologies, a network-side device may initiate a capability transmission process to a UE in a connected state to obtain UE wireless access capability information. After receiving a UE capability query message (UECapabilityEnquiry) sent by a network-side device, the UE sends a UE capability information message (UECapabilityInformation) to the network, wherein the UE capability information message may carry the UE capability information. In an embodiment of the present application, the UE capability information message may be multiplexed, and a first request message may be sent in the UE capability information message to request capability changes and / or configuration preferences for multiple card purposes.

[0049] In another possible implementation of the embodiment of the present application, the first request information may also be sent via a radio resource control (RRC) connection establishment completion message (RRC Setup Complete). That is, the first request information is sent in the RRC connection establishment completion message sent by the UE to the network side device when the RRC connection establishment with the network side is completed.

[0050] In the above possible implementation, the RRC connection establishment complete message carries the first capability information of the UE, wherein the first capability information is different from the second capability information, the second capability information is the capability information most recently reported by the UE, or the second capability information is the capability information reported during the UE registration network, or the second capability information is the maximum capability information of the UE. For example, the second capability is 4MIMO and the first capability is 2MIMO. Alternatively, the second capability supports dual connectivity and the first capability does not support dual connectivity.

[0051] In the above possible implementation, the capability information of the UE is the first capability information during the RRC connection state corresponding to the RRC connection establishment complete message. That is, the capability of the UE is the first capability during this RRC connection state and remains unchanged.

[0052] S214: The UE performs corresponding processing based on the response of the network side device.

[0053] After the UE sends the first request message to the network side device, the UE performs corresponding processing based on the response of the network side device to the first request message.

[0054] After receiving the first request message, the network side device may respond to the first request message. Therefore, in a possible implementation, step S214 may include:

[0055] The UE monitors a response message sent by the network side device;

[0056] In case of monitoring the response message, the UE performs corresponding processing based on the response message.

[0057] In the above possible implementation manner, the above response message may be an RRC reconfiguration message, that is, the network side device reconfigures the terminal after receiving the first request message.

[0058] Alternatively, the response message may also be other messages, which may carry at least one of the following information:

[0059] (1) Acceptance information, wherein the acceptance information indicates that the network side device accepts the first request information; that is, it indicates that the network side device accepts the first request information sent by the terminal.

[0060] (2) Reconfiguration information: The network side device may reconfigure the UE according to the first request information. For example, the reconfiguration meets the capability requirements of the UE, or the reconfiguration does not exceed the capability requested by the UE.

[0061] In the above possible implementations, optionally, when the UE performs corresponding processing based on the response message, in the case where the response message carries the acceptance information, the UE applies the requested capability change and / or the configuration preference. That is, the capability change and / or configuration preference requested by the UE takes effect.

[0062] Alternatively, when the response message carries the reconfiguration information or the response message is an RRC reconfiguration message, the UE performs a reconfiguration process based on the reconfiguration information or the RRC reconfiguration message.

[0063] Alternatively, the capability change and / or configuration preference requested by the UE may take effect when the UE receives the response message. That is, by default, the capability change and / or configuration preference takes effect after the UE receives the response message from the network.

[0064] In a possible implementation, the network side device may configure a first timer, or the protocol may agree on the first timer, and the UE may monitor the response message sent by the network side device, which may include: after sending the first request information, the UE starts the first timer, wherein the duration of the first timer is configured by the first configuration information, or the duration of the first timer is pre-agreed; during the operation of the first timer, the UE monitors the response message sent by the network side device. That is, in this possible implementation, the UE monitors the response of the network side device within a predetermined time period after sending the first request information.

[0065] In the above possible implementation, the UE starts the first timer including: when it is determined that the network side device needs to be reconfigured, the UE starts the first timer after sending the first request information. That is, if the capability change and / or preference configuration requested by the first request information sent by the UE requires the network side device to be reconfigured, the UE starts the first timer to listen to the response of the network side device.

[0066] Optionally, the UE determines that the network side device needs to be reconfigured, which may include at least one of the following: the first request information includes reconfiguration indication information, the first request information includes reconfiguration indication information and the reconfiguration indication information indicates that the network side device needs to reconfigure the UE, the UE requests a capability change, and the UE current configuration does not meet the preferred configuration requested by the UE. For example, the UE capability becomes smaller after the capability change, but the current configuration is greater than the capability after the UE capability change, so the network side device needs to reconfigure the UE.

[0067] Optionally, during the operation of the first timer, the UE is not allowed to send the first request information again; or, during the operation of the first timer, the UE is not allowed to send a second request information requesting a capability change and / or configuration preference, and the second request information is different from the first request information. That is, during the operation of the first timer, the UE monitors the response message of the network, and during the operation of the first timer, the UE cannot send the same first request information again, or the UE cannot send a second request information requesting a capability change and / or configuration preference.

[0068] In a possible implementation, after starting the first timer, the method further includes: during the running of the first timer, the UE stops the first timer in one of the following situations:

[0069] (1) receiving the response message sent by the network side device;

[0070] (2) The response message sent by the network side device is received, and the response message satisfies the configuration preference of the UE. For example, if the response message includes reconfiguration information, then if the reconfiguration information satisfies the configuration preference of the UE, the first timer is stopped. Alternatively, if the response message is a reconfiguration message, then if the reconfiguration message satisfies the configuration preference of the UE, the first timer is stopped.

[0071] That is, if the first timer is running, the conditions for the UE to stop the timer include one of the following:

[0072] (1) The UE receives a response message (eg, a reconfiguration message) from the network, and the UE stops the first timer.

[0073] (2) The UE receives a reconfiguration message or reconfiguration information sent by the network, and the reconfiguration message or reconfiguration information satisfies the configuration preference of the UE, and the UE stops the first timer.

[0074] In a possible implementation, the UE performs corresponding processing based on the response of the network side device, further comprising: when the first timer times out, the UE performs a first operation. For example, before the first timer times out, the UE does not receive a response message from the network side device, or the received reconfiguration message or reconfiguration information does not meet the UE's configuration preference, then the UE performs the first operation.

[0075] Optionally, the first operation includes but is not limited to at least one of the following:

[0076] (1) Enabling the preference configuration and / or capability change of the UE; the preference configuration and / or capability change may be requested by the first request information, or may not be requested by the first request information.

[0077] (2) Enabling the configuration and / or capability corresponding to the first request information; for example, the preferred configuration requested by the first request information, or the capability change requested by the first request information, that is, the changed capability.

[0078] (3) Deactivate the secondary cell group (SCG) connection;

[0079] (4) Release the SCG connection; that is, the UE releases the SCG connection locally.

[0080] (5) Reduce the number of multiple-input multiple-output (MIMO) layers; for example, fall back from 4MIMO to 2MIMO.

[0081] (6) Reducing the number of downlink carrier aggregation (DL CA); for example, reducing DL CA from 6 carrier aggregation (CA) to 5 CA.

[0082] (7) Reduce the number of uplink carriers (UL CA);

[0083] (8) resending the first request information;

[0084] (9) Performing a network switching operation. For example, switching from network A to network B. For example, based on the purpose of network switching, the UE sends a first request message to the network side device. When the first timer times out, the UE does not receive a response from the network side device, and the UE automatically switches from network A to network B.

[0085] In the above possible implementation, a processing scheme for the UE is given when the network does not respond to or satisfy the UE's request after the UE requests a capability change or configuration preference for multi-card purposes, which effectively improves the capability change or configuration negotiation and improves the performance of multi-card UE network conversion.

[0086] In a possible implementation, if the UE monitors a response message sent by the network side device before the first timer expires, the UE performs corresponding processing based on the response message. Optionally, the processing that can be performed includes one of the following:

[0087] (1) when the response message satisfies the configuration preference of the UE, the UE performs a second operation;

[0088] The second operation may include at least one of the following:

[0089] a) when the first timer is running, the UE stops the first timer;

[0090] b) The UE performs a reconfiguration process based on the response message; for example, performs a reconfiguration process based on the reconfiguration information carried in the response message, or performs a reconfiguration process based on the received reconfiguration message.

[0091] c) The UE performs network switching after the reconfiguration process is completed.

[0092] For example, the UE requests to deactivate the SCG in the first request information, and the network side device sends a reconfiguration message to deactivate the SCG. The UE can execute: if the first timer is running, the UE stops the first timer; the UE executes the reconfiguration process; and executes the network conversion after the reconfiguration process is completed.

[0093] (2) If the response message does not meet the configuration preference of the UE, if the first timer is running, the UE stops the first timer and performs the first operation; for example, if the reconfiguration information carried in the response message or the reconfiguration message returned by the network side device does not meet the configuration preference of the UE, if the first timer is running, stop the timer and perform the above-mentioned first operation.

[0094] (3) If the response message does not satisfy the configuration preference of the UE, and if the first timer is running, the UE performs the first operation after the first timer times out. For example, if the reconfiguration information carried in the response message or the reconfiguration message returned by the network side device does not satisfy the configuration preference of the UE, and if the first timer is running, the UE does not stop the timer, but waits for the first timer to time out before performing the above-mentioned first operation.

[0095] The above (2) and (3) give the UE's processing method if the network does not meet the UE's request after the UE requests capability change and / or configuration preference for multi-card purposes, which effectively improves the solution for capability change and / or configuration negotiation and improves the performance of multi-card UE network conversion.

[0096] In a possible implementation, the network side device may also send first configuration information to the UE to indicate whether the UE is allowed to send the first request information, that is, whether the UE is allowed to request a capability change and / or configuration preference. Therefore, before S210, the method may also include: receiving the first configuration information sent by the network side device, wherein the first configuration information is used to indicate that the UE is allowed to send the first request information. After receiving the first configuration information, the UE sends the first request information to the network side device when there is a need for capability change and / or configuration preference.

[0097] Optionally, the first configuration information may include at least one of the following information:

[0098] (1) First indication information, wherein the first indication information indicates support for configuration preference and / or capability change of the terminal; for example, the first configuration information includes an indication bit, through which the network side device indicates whether the configuration preference and / or capability variable of the terminal is supported.

[0099] (2) Duration of the first timer. Alternatively, the duration of the first timer may be a protocol agreement. In the case where the duration of the first timer is included, the first configuration information may not include the first indication information, that is, if the duration of the first timer is configured in the first configuration information, it is assumed that the network side device supports the configuration preference and / or capability change of the terminal.

[0100] Optionally, the first configuration information may be sent via a system information (SI) message, or may be sent via an RRC reconfiguration message. For example, the first configuration information is carried in the OtherConfig IE of the RRC reconfiguration message.

[0101] In the embodiment of the present application, a negotiation scheme for capability change and / or configuration preference of multi-card UE is provided. After the UE requests capability change or configuration preference for multi-card task, corresponding processing can be performed according to the response of the network side device. The UE processing operation is provided in the case that the network does not respond to or does not meet the UE's request, which effectively improves the capability change or configuration negotiation and improves the performance of multi-card UE network conversion.

[0102] Figure 3 Another flow chart of the method for changing the capability of a UE provided in an embodiment of the present application is shown. The method 300 can be executed by a network-side device. In other words, the method can be executed by software or hardware installed on the network-side device. Figure 3 As shown, the method may include the following steps.

[0103] S310, a network side device receives first request information sent by a UE, wherein the first request information is used to request a capability change and / or configuration preference of the UE.

[0104] The UE may send the first request information according to method 200 , and the first request information is the same as the first request information in method 200 , and details may refer to the description in method 200 .

[0105] S312: The network side device responds to the first request information.

[0106] In an embodiment of the present application, the network side device may respond to the first request information according to its own operation status, for example, a response message may be sent to the UE, the response message indicating acceptance of the first request information and / or carrying reconfiguration information, or a reconfiguration message may be sent to the UE. The reconfiguration information or the reconfiguration message may or may not satisfy the configuration preference of the UE.

[0107] In a possible implementation, the first request information may carry at least one of the following information:

[0108] Configuration preference information, wherein the configuration preference information is used to indicate a configuration desired by the UE;

[0109] Capability change requirement information, wherein the capability change requirement information is used to indicate that the UE needs capability change;

[0110] Reconfiguration indication information, wherein the reconfiguration indication information is used to indicate that the network side device needs to reconfigure the UE, or the reconfiguration indication information is used to indicate that the network side device does not need to reconfigure the UE;

[0136] Optionally, the first request message includes at least one of the following contents:

[0137] (1) Configuration Preference, which indicates the configuration desired by the UE, for example:

[0138] a) Configuration upper limit: That is, the UE expects the network configuration not to exceed the configuration preference.

[0139] b) Configure preferred time information, including duration, period, start time, etc.

[0140] c) UE requests periodic configuration switching. For example, NW A sends two sets of configurations to the UE. The UE switches the configurations at NW A according to the period.

[0141] d) Multi-card configuration preference: This configuration preference is used for multi-card purposes.

[0142] (2) Capability change requirement: The capability change requirement indicates that the UE needs to change its capabilities. The UE expects the network configuration to not exceed the capability.

[0143] (3) Reconfiguration indication. The reconfiguration requirement indication indicates that the UE requires the network to reconfigure the UE. For example:

[0144] a) Reconfiguration required: Configuration preference or capability change requirement may require the network to reconfigure the UE. For example, the current configuration has dual connectivity (MR-DC SCG), the UE capability is changed to not support dual connectivity, and the network is expected to release the SCG connection.

[0145] b) No reconfiguration required: Configuration preference or capability change requirements may not require the network to reconfigure the UE. For example, dual connectivity (MR-DC SCG) is not configured in the current configuration. The UE sends a first request message to expect the network not to configure dual connectivity. At this time, the network does not need to initiate a reconfiguration of the corresponding first request message.

[0146] (4) Multi-SIM purpose: The UE indicates that the first request message is for multi-SIM purpose, not for power saving or overheating.

[0147] Optionally, the first request information may be carried by the following message:

[0150] -RRC connection establishment is completed (RRC Setup Complete). When the first request information is carried by the RRCSetupComplete message, the UE's capability information is the first capability information, and the first capability information may be different from the UE's second capability. For example, the second capability may be the original capability of the terminal or the capability reported last time. Optionally, the UE's capability is the first capability during this RRC connection state and remains unchanged. The original capability of the UE corresponds to the capability reported by the UE during the registration network, or the maximum capability of the UE. For example:

[0151] a) The original capability is 4MIMO and the first capability is 2MIMO.

[0152] b) The original capability supports dual connections, but the first capability does not support dual connections.

[0153] S412: The network sends a response message to the UE.

[0154] The response message may include one or more of the following information:

[0155] -The network accepts the first request message.

[0156] - Reconfiguration information. The network reconfigures the UE according to the request information, for example, to ensure that the configuration meets the capability requirements of the UE or to avoid configuration that exceeds the capability requested by the UE.

[0202] a) If the first timer is running, the UE stops the first timer;

[0203] b) UE performs reconfiguration process
