Description

Terminal capability control method, terminal and base station

Technical Field

The present invention relates to the field of communications, and in particular, to a terminal capability control method, a terminal, and a base station.

Background

In an LTE-DC scenario, that is, when an MN (Master Node) is an LTE eNB and an SN (Secondary Node) is also an LTE eNB scenario, the MN is responsible for the configuration of the MN and the SN, and the MN does not need to negotiate the UE capability and configuration with the SN, and the MN can completely understand the UE capability and the configuration at the SN side. The MN is the only controlling node.

An EN-DC scenario, namely MN is LTE eNB and SN is NR gNB. The UE may report LTE capability and NR capability of the UE respectively, when the network configures the UE, the MN side and the SN side at least need to negotiate band combination (band combining Access RATs) across RATs (Radio Access technologies) and capability of caching a buffer across layer 2 of RATs, and for the capability that needs to negotiate, the network MN may also trigger negotiation through interface signaling between networks by the SN, and the network MN makes a final decision. The network side MN and the SN do not need to understand the UE configuration of the other side mutually. The SN can be independently responsible for partial configuration of the SN, and the MN side is no longer the only control node.

The design of the capability of the proposed NR at RAN2 #97 conference requires consideration of three issues:

1: the hardware sharing is that NR shares hardware with other hardware such as WLAN (Wireless Local Area Network), BT (bluetooth), GPS (Global Positioning System), etc.

2: interference, i.e. interference of NR with other, e.g. WLAN, BT, GPS etc.

3: other UE problems, such as an overheating problem.

The prior art only provides a solution for temporarily limiting the capability of the UE for an overheating scenario of LTE single connection. But for dual-connection or multi-connection scenarios, such as EN-DC scenarios, the UE side may be faced with both overheating due to configuration from the network side MN and/or SN, or hardware sharing and interference issues with WLAN, BT, GPS, etc. due to configuration at the SN side. There is currently no clear solution to elaborate how to control the temporary limit UE capability in a multi-connection scenario, such as an EN-DC scenario.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

In some embodiments of the present invention, referring to fig. 1, a terminal capability control method is provided, which is applied to a terminal and includes:

step 101, sending a request message for requesting to limit the capability of the terminal UE to the network side, wherein the content of the request message comprises a request for limiting the configuration of the UE main base station MN side and/or the auxiliary base station SN side.

The first RAT may be LTE, the second RAT may be NR, that is, MN is an LTE base station, and SN is an NR base station, that is, an EN-DC scenario. Or the first RAT may be NR and the second RAT is NR, i.e. both MN and SN are NR base stations.

Of course, the first RAT and the second RAT are not limited to the above two cases, and other radio access technologies may be adopted, which are not described herein.

The terminal capacity control method of the embodiment of the invention aims at multiple connection scenes such as EN-DC and the like, UE sends a request message for requesting to limit the capacity of the UE to a network side, and the content of the request message comprises a request for limiting the configuration of an MN side and/or an SN side of the UE, thereby providing a specific method for temporarily limiting the capacity of the UE, solving the problems of overheating, strong interference, hardware sharing and the like of the EN-DC scene, and being applicable to other multiple connection scenes.

Optionally, the step 101 includes:

step 1011, always sending a request message for requesting to limit the UE capability to the network side through the signaling bearer of the MN side, where the content of the request message includes a request for limiting the configuration of the UE MN side and/or the SN side.

Here, for any scenario, the UE always sends a request message requesting to limit the UE capability to the network side through a signaling bearer SRB (signaling Radio Bearers) on the MN side, and requests to limit the configuration on the MN side and/or the SN side of the UE.

For example, in an EN-DC scenario, when the UE detects that the device is overheated and meets a condition of reporting a request for limiting the UE capability triggered by overheating, the UE always sends a request message requesting to limit the UE capability to the network side through the SRB of the MN side, and requests to limit the configuration of the MN side and/or the SN side of the UE.

When the UE detects that strong interference exists between SN and WLAN, BT, GPS and the like or between SN and MN and meets the condition that the strong interference triggers and reports the request for limiting the terminal capability, the UE always sends a request message for limiting the UE capability to the network side through the SRB of the MN side to request to limit the configuration of the MN side and/or the SN side of the UE.

When the UE detects that the SN is shared with hardware such as a WLAN, a BT, a GPS and the like, the hardware sharing comprises the sharing of the hardware such as an antenna, a processor and the like, and meets the condition that the hardware sharing triggers the reporting of the request for limiting the UE capacity, the UE always sends a request message for limiting the UE capacity to a network side through an SRB of the MN side, and the request is for limiting the configuration of the MN side and/or the SN side of the UE.

Alternatively, the step 101 includes:

step 1012, sending a request message for requesting to limit the UE capability to the network side through the signaling bearer of the MN side or the signaling bearer of the SN side, where the content of the request message includes a request for limiting the configuration of the SN side of the UE.

Here, when requesting a request message for restricting the configuration of the SN side of the UE, the UE may request to restrict the configuration of the SN side of the UE by transmitting a request message for restricting the UE capability to the network side through a signaling bearer of the MN side or a signaling bearer of the SN side.

For example, in an EN-DC scenario, when the UE detects that the device is overheated and meets a condition for triggering reporting of a request for limiting the UE capability by overheating, the UE requests to limit the configuration of the SN side only, and the UE may send a request message for limiting the UE capability to the network side through the signaling bearer SRB of the MN side to request to limit the configuration of the SN side of the UE, or if the signaling bearer SRB3 of the SN side is configured, the UE may send a request message for limiting the UE capability to the network side through the SBR3 to request to limit the configuration of the SN side of the UE.

When the UE detects that strong interference exists between SN and WLAN, BT, GPS and the like or between SN and MN and meets the condition that the strong interference triggers and reports the request for limiting the terminal capability, the UE can send a request message for limiting the UE capability to the network side through the signaling bearing SRB of the MN side to request to limit the configuration of the SN side of the UE, or if the signaling bearing SRB3 of the SN side is configured, the UE can send a request message for limiting the UE capability to the network side through SBR3 to request to limit the configuration of the SN side of the UE.

When the UE detects that the SN is shared with hardware such as a WLAN, a BT, a GPS and the like, the hardware sharing comprises the sharing of the hardware such as an antenna, a processor and the like, and meets the condition that the hardware sharing triggers and reports the request for limiting the UE capacity, the UE can send a request message for limiting the UE capacity to the network side through the signaling bearing SRB of the MN side to request to limit the configuration of the SN side of the UE, or if the signaling bearing SRB3 of the SN side is configured, the UE can send the request message for limiting the UE capacity to the network side through the SBR3 to request to limit the configuration of the SN side of the UE.

The conditions for triggering reporting of the request for limiting the UE capability are not limited, and any condition that the request for limiting the UE capability needs to be reported can be used in the present invention, which is not described herein. For example, when the temperature of the UE is greater than a certain threshold value within a period of time and a certain high-order configuration exists, it is determined that a condition for reporting a request for limiting the UE capability by triggering overheating is satisfied; when a certain index in a signal measured by the UE is abnormal, determining that the condition of reporting a request for limiting the UE capability triggered by strong interference is met.

Optionally, before step 101, the method further includes:

step 1001, when it is detected that the terminal UE meets the condition of reporting the request for limiting the UE capability through overheat triggering, according to the current configuration information of the UE MN side and the configuration information of the SN side, determining whether to request to limit the configuration of only the UE MN side or the SN side or to limit the configuration of both the UE MN side and the SN side.

Here, when the UE detects that the condition of reporting the request for limiting the UE capability is met by the overheat trigger, the UE sends a request message for limiting the UE capability to the network side, and the UE can determine whether to request to limit only the configuration of the UE MN side or the SN side or to limit the configurations of the UE MN side and the SN side at the same time according to the configuration information of the current MN side and the configuration information of the SN side.

The configuration information of the MN side at least includes one or more of the number of MIMO layers, modulation schemes, and Carrier Aggregation (CA) number supported by the UE configured on the MN side; the configuration information of the SN side at least comprises one or more items of MIMO layer number, modulation scheme and carrier number supported by the UE configured by the SN side.

Further, when the UE detects that the condition of limiting the UE capability request by triggering reporting is met due to overheating, the UE sends a request message for limiting the UE capability to the network side, and at this time, the UE may report the capability level category of the MN side and/or the SN side separately, or in an EN-DC scenario, if the EN-DC category is defined, the UE may report the EN-DC category. As described in detail below.

Optionally, the method further includes:

and 102, reporting the reduced capability level reduced category of the UE MN side and/or the reduced capability level reduced category of the UE SN side to the network side through the request message.

At this time, when the UE detects that the condition of reporting the UE capability restriction request triggered by overheating is satisfied, the UE reports a reduced category of the MN side and/or a reduced category of the SN side separately.

For example, when the UE requests to limit the configuration of the MN side, the UE provides a reduced category of the MN side in the request message. When the UE requests to restrict the configuration of the SN side, the UE provides a reduced category of the SN side in a request message. At this time, the request message is always sent to the network side through the SRB of the MN side, or if the SRB3 of the SN side is configured, the request message may be sent to the network side through the SRB3 of the SN side or the SRB of the MN side when only the configuration of the SN side is limited.

Optionally, the reduced capability level reduced category of the MN side at least includes one or more of a terminal capability level UE category defined by the MN side, a number of MIMO layers supported by the UE, and a modulation scheme supported by the UE; the reduced capability level reduced category of the SN side at least comprises one or more of a terminal capability level UE category defined by the SN side, a number of MIMO layers supported by the UE, and a modulation scheme supported by the UE.

Here, when the MN is an LTE base station and the SN is an NR base station, the MN side at least includes one or more of a UE category defined by LTE, a number of MIMO layers supported by UE, and a modulation scheme supported by UE, and the reduced category of the SN side at least includes one or more of a UE category defined by NR, a number of MIMO layers supported by UE, and a modulation scheme supported by UE.

Optionally, the method further includes:

103, reporting the reduced EN-DC capability level reduced by the UE to a network side through the request message; or reporting the UE reduced EN-DC category and the indication information for limiting the configuration of the UE MN side and/or the SN side to the network side through the request message.

At this time, if an EN-DC category is defined, which defines UE capabilities on the UE MN side and the SN side for the EN-DC scenario, when the UE detects that a condition for triggering reporting a request to limit the UE capabilities due to overheating is satisfied, the UE may report the reduced EN-DC category, or report the reduced EN-DC category and indication information for limiting the configuration on the UE MN side and/or the SN side. At this time, the request message is always sent to the network side through the SRB of the MN side.

In the embodiment of the invention, when the UE detects that the overheating problem is removed, the UE can apply to the network side to remove the limitation on the UE capability and recover the UE capability, and the flow is the same as the flow of applying to limit the UE capability by the UE side.

Optionally, the method further includes:

step 104, reporting the maximum capability level of the MN side and/or the SN side supported by the UE to the network side through the request message; or reporting the identifier indicating the capability of the recovery terminal to the network side by the MN side and/or the SN side implicitly or displaying the identifier through the request message.

At this time, when the UE detects that the overheating problem is resolved, the UE sends a request message for limiting the UE capability to the network side, and the UE may carry the maximum capability level category of the MN side and/or the SN side supported by the UE in the request message, or carry a special value agreed by the network side and the UE in the request message to implicitly notify the network side to recover the UE capability configuration, or carry a explicit identifier in the request message to notify the network side to recover the UE configuration.

Optionally, the step 101 includes:

Here, when the UE detects that there is strong interference between the SN and the WLAN, BT, GPS, etc., or that there is strong interference between the SN and the MN, and meets the condition that the strong interference triggers reporting of the request for limiting the UE capability, the UE sends a request message requesting to limit the UE capability to the network side, requesting to limit the configuration of the SN side of the UE. At this time, the UE may always send a request message requesting to limit the UE capability to the network side through the signaling bearer SRB of the MN side, requesting to limit the configuration of the SN side of the UE, or if the signaling bearer SRB3 of the SN side is configured, the UE may send a request message requesting to limit the UE capability to the network side through the SBR3 of the SN side or the SRB of the MN side, requesting to limit the configuration of the SN side of the UE.

In the embodiment of the invention, when the UE detects that the strong interference problem is removed, the UE can apply to the network side to remove the limitation on the UE capability and recover the UE capability, and the flow is the same as the flow of applying to limit the UE capability by the UE side.

Optionally, the method further includes:

step 105, reporting the frequency point information needing to be limited and/or the frequency point information needing to be recovered to a network side through the request message; and reporting the information of the frequency points to be limited and recovered and the limit or recovery indication information corresponding to each frequency point to a network side through the request message.

At this time, when the UE detects that the condition of reporting the request for limiting the UE capability is met by strong interference trigger, the UE sends a request message requesting to limit the UE capability to the network side, and requests to limit the configuration of the SN side of the UE, and the UE may carry frequency point information to be limited in the request message, such as a first frequency point capability list, where the list includes the frequency point information to be limited, or the UE may carry the frequency point information to be limited and restored and limitation or restoration indication information corresponding to each frequency point, such as a second frequency point capability list and limitation or restoration indication information corresponding to each frequency point included in the list, where the list includes the frequency point information to be limited and restored.

When the UE detects that the strong interference problem is relieved, the UE sends a request message requesting to limit the UE capacity to a network side and requests to recover the configuration of the SN side of the UE, the UE can carry frequency point information needing to be recovered in the request message, such as a third frequency point capacity list, wherein the list comprises the frequency point information needing to be recovered, or the UE can carry the frequency point information needing to be limited and recovered and limitation or recovery indication information corresponding to each frequency point in the request message, such as a second frequency point capacity list and limitation or recovery indication information corresponding to each frequency point in the list, wherein the list comprises the frequency point information needing to be limited and recovered.

Optionally, the step 101 includes:

Here, when the UE detects that there is hardware sharing between the SN and the WLAN, BT, GPS, etc., the hardware sharing includes sharing of hardware such as an antenna, a processor, etc., and meets a condition that the hardware sharing triggers reporting of a request for limiting UE capability, the UE sends a request message requesting to limit UE capability to the network side, requesting to limit configuration of the SN side of the UE. At this time, the UE may always send a request message requesting to limit the UE capability to the network side through the signaling bearer SRB of the MN side, requesting to limit the configuration of the SN side of the UE, or if the signaling bearer SRB3 of the SN side is configured, the UE may send a request message requesting to limit the UE capability to the network side through the SBR3 of the SN side or the SRB of the MN side, requesting to limit the configuration of the SN side of the UE.

In the embodiment of the invention, when the UE detects that the hardware sharing problem is removed, the UE can apply to the network side to remove the limitation on the UE capability and recover the UE capability, and the flow is the same as the flow applying to limit the UE capability by the UE side.

Optionally, the method further includes:

step 106, reporting the information of the shared hardware or the frequency point which needs to be limited and/or the information of the shared hardware or the frequency point which needs to be recovered to a network side through the request message; and reporting the information of the shared hardware or the frequency point which needs to be limited and recovered and the limitation or recovery indication information corresponding to each shared hardware or frequency point to a network side through the request message.

At this time, when the UE detects that the condition of reporting the request for limiting the UE capability is met by hardware sharing trigger, the UE sends a request message requesting to limit the UE capability to the network side, the request message requests to limit the configuration of the SN side of the UE, and the UE may carry shared hardware (such as an antenna or a processor) or frequency point information that needs to be limited in the request message, such as a first shared list, where the list includes the shared hardware or frequency point information that needs to be limited, or the UE may carry the shared hardware or frequency point information that needs to be limited and recovered and limitation or recovery indication information corresponding to each shared hardware or frequency point in the request message, such as a second shared list and limitation or recovery indication information corresponding to each shared hardware or frequency point in the list, where the list includes the shared hardware or frequency point information that needs to be limited and recovered.

When the UE detects that the hardware sharing problem is resolved, the UE sends a request message requesting to limit the UE capability to the network side, and requests to recover the configuration of the SN side of the UE, where the UE may carry shared hardware (such as an antenna or a processor) or frequency point information to be recovered in the request message, such as a third shared list, where the list includes the shared hardware or frequency point information to be recovered, or the UE may carry the shared hardware or frequency point information to be limited and recovered and limitation or recovery indication information corresponding to each shared hardware or frequency point in the request message, such as a second shared list and limitation or recovery indication information corresponding to each shared hardware or frequency point in the list, where the list includes the shared hardware or frequency point information to be limited and recovered.

In the embodiment of the invention, after the network side receives the request message which is sent by the UE and requests to limit the capability of the UE, the network side can determine whether to accept the request of the UE. If the content of the request message contains a request for limiting the configuration of the MN side of the UE, the MN side can judge whether to accept the request of the UE or not, and reconfigure the configuration of the MN side of the UE when accepting the request of the UE. If the configuration change of the MN side needs to be negotiated with the SN side, the MN negotiates with the SN side, the negotiation result is determined by the MN, and the MN generates the reconfiguration message of the MN side according to the negotiation result. If the configuration of the MN side is changed and the SN side needs to be reconfigured, the SN generates a reconfiguration message of the SN side. If the content of the request message contains a request for limiting the configuration of the SN side of the UE, if the request message can be successfully analyzed by the MN, the MN can decide whether to accept the request of the UE and send the request message to the SN, if the request message can not be successfully analyzed by the MN, the request message is sent to the SN, whether to accept the request of the UE is judged by the SN, and the SN reconfigures the configuration of the MN side of the UE when the request of the UE is accepted. If the UE reconfiguration needs the negotiation between the SN and the MN side, the SN triggers the negotiation with the MN side and makes a final decision, and the SN reconfigures the configuration of the SN side of the UE according to the negotiation result.

If the MN side and the SN side need to be reconfigured after negotiation, the SN generates reconfiguration information of the SN side, the MN generates reconfiguration information of the MN side, the SN sends the reconfiguration information of the SN side to the MN, and the MN encapsulates the reconfiguration information of the SN side and the reconfiguration information of the MN side together and sends the reconfiguration information of the SN side and the reconfiguration information of the MN side to the UE through the SRB of the MN side. If only the reconfiguration message of the SN side exists and the MN side does not need to reconfigure, the reconfiguration message of the SN side may be sent to the UE through the SRB of the MN side or through the SRB3 of the SN side (if the SRB3 is configured). If only the reconfiguration message of the MN side exists, the reconfiguration message of the MN side is sent to the UE through the SRB of the MN side.

Optionally, the method further includes:

step 111, receiving a reconfiguration message of the UE MN side and/or the SN side sent by the network side;

and 112, reconfiguring the configuration of the MN side and/or the SN side of the UE according to the reconfiguration message.

At this time, the UE receives a reconfiguration message of the MN side and/or the SN side sent by the network side, and when the reconfiguration message of the MN side exists, the UE reconfigures the configuration of the MN side according to the reconfiguration message of the MN side, and when the reconfiguration message of the SN side exists, the UE reconfigures the configuration of the SN side according to the reconfiguration message of the SN side.

And after the reconfiguration is successful, generating a corresponding reconfiguration completion message according to the reconfiguration message, and sending the reconfiguration completion message to the network side through the same SRB as the SRB for receiving the reconfiguration message.

The scenarios that the UE reporting request is triggered to limit the UE capability under the EN-DC scenario include overheating, sharing of SN with hardware such as WLAN, BT and GPS, or existence of strong interference. As shown in fig. 2, the method for controlling terminal capability according to the embodiment of the present invention provides a method for limiting UE capability in EN-DC scenarios, where steps 1-a and 1-b are two possible ways for a UE to report a request message requesting to limit UE capability, the UE may report the request message limiting UE capability to a network side through an SRB of an MN side, and if the request message limiting SN side configuration is included, the MN sends the request message to an SN, or when the content of the request message only includes a request limiting SN side configuration and the UE configures an SN side SRB3, the request message limiting UE capability may be reported to the network side through an SN side SRB 3. Step 2 is that when the SN side needs to negotiate with the MN side, the MN or the SN triggers a capability negotiation process. And 3-a and 3-b are two ways for the network side to reconfigure the UE according to the request reported by the UE. Step 3-a is that MN sends the reconfiguration message of MN side and/or SN side to UE through SRB of MN side, UE reconfigures according to the reconfiguration message, and sends the reconfiguration complete message to MN through SRB of MN side, MN receives the reconfiguration complete message sent by UE, if the reconfiguration complete message includes the reconfiguration complete message of SN side, then sends the reconfiguration complete message of SN side to SN through interface message between MN and SN. And 3-b, sending the reconfiguration message of the SN side to the UE through the SRB3 of the SN side for the SN, carrying out reconfiguration by the UE according to the reconfiguration message of the SN side, and sending the reconfiguration completion message of the SN side to the SN through the SRB3 of the SN side. The UE requests the capability to be recovered and the UE capability is limited to use the same request message and the same flow, except that the content assignment of the request message is different.

The following describes a specific application flow of the terminal capability control method according to the embodiment of the present invention with reference to a specific application scenario.

In a first scenario and an EN-DC overheating scenario, UE independently reports categories of an MN side and an SN side, and configuration of the MN side of the UE is limited:

UE-side behavior:

and 11, the UE detects that the equipment is overheated and meets the condition that overheating triggers the request for reporting the limitation of the UE capacity, and the UE prepares to report a request message for requesting the limitation of the UE capacity.

12, the UE detects that the configuration of the SN side does not have a condition of reporting the request for limiting the UE capability through overheating trigger, that is, the SN side does not have a configuration of high-order MIMO, high-order CA, or high-order modulation scheme, but the configuration of the MN side meets the condition of reporting the request for limiting the UE capability through overheating trigger, that is, the SN side is not a main source of overheating, and the MN side is a main source of overheating, so the UE sends a request message requesting to limit the UE capability to the network side, and the content of the request message includes a configuration requesting to limit only the MN side of the UE.

And 13, the UE carries the recommended reduced category of the MN side in the request message according to the configuration of the current MN side and the capability of the UE. The request message is sent to the network side through the SRB of the MN side.

And 14, the UE receives a reconfiguration message sent by the network side from the SRB of the MN side, wherein the reconfiguration message comprises the reconfiguration message of the MN side of the UE, and the UE reconfigures the configuration of the MN side of the UE according to the reconfiguration message. If the reconfiguration message contains the reconfiguration message of the SN side of the UE, the UE reconfigures the configuration of the SN side of the UE according to the reconfiguration message of the SN side. If the UE is successfully reconfigured, the UE sends a reconfiguration complete message to the network side, and the message is sent through the SRB of the MN side.

And 15, when the UE detects that the overheating problem is relieved, applying for relieving the temporary UE capacity limitation to the network side to recover the UE capacity, wherein the flow is the same as the flow for applying for limiting the UE capacity by the UE side, and the UE can implicitly inform the network side to recover the UE capacity configuration by carrying the maximum category supported by the UE MN side or a special value agreed by the network side and the UE side in the request message or implicitly inform the network side to recover the UE capacity configuration by carrying a dominant identifier in the request message.

Network side behavior:

21. the method comprises the steps that a network side MN receives a request message which is sent by UE and requests to limit the capability of the UE, detects that the request message only carries reduced category of the MN side, and the MN judges whether to accept the request of the UE.

22. If the MN accepts the request of the UE, the MN reconfigures the UE according to the reduced category of the MN side sent by the UE, and the process is decided by the MN side. If the configuration of the MN side is changed and the SN side needs to be reconfigured, the MN negotiates with the SN side, the MN determines a negotiation result, the SN generates a reconfiguration message of the SN side according to the negotiation result, and the MN encapsulates the reconfiguration message of the SN side and the reconfiguration message of the MN side into the reconfiguration message of the MN side.

And 23, the MN sends the reconfiguration message to the UE through the SRB of the MN side.

And 24, the MN receives a reconfiguration complete message sent by the UE, and if the reconfiguration complete message contains a reconfiguration complete message at the SN side, the reconfiguration complete message is sent to the SN through an interface message between the MN and the SN.

25. If the MN receives a request message requesting to limit the UE capability sent by the UE, where the request message carries a maximum category supported by the UE MN or a special value agreed by the network side and the UE side implicitly indicates that the UE side requests to recover the UE capability, or the request message carries an explicit identifier requesting the network side to recover the UE capability, the network side MN may determine whether to reconfigure the UE, and the flow is the same as the flow for limiting the UE capability.

And in a scene II and an EN-DC overheating scene, independently reporting the categories of the MN side and the SN side by the UE, and limiting the configuration of the SN side of the UE:

UE-side behavior:

and 31, the UE detects that the equipment is overheated and meets the condition that overheating triggers the request for reporting the limitation of the UE capacity, and the UE prepares to report a request message for requesting the limitation of the UE capacity.

32, the UE detects that the configuration of the MN side does not have a condition for triggering the request for limiting the UE capability by reporting too much, that is, the MN side does not have a configuration of a high-order MIMO, a high-order CA, or a high-order modulation scheme, but the configuration of the SN side satisfies the condition for triggering the request for reporting the UE capability by too much, that is, the SN side is a main source of overheating, so the UE side sends a request message for limiting the UE capability to the network side, and the content of the request message only includes a request for limiting the configuration of the SN side.

And the UE carries a recommended reduced category of the SN side in the request message according to the configuration of the current SN side and the capability of the UE, wherein the reduced category comprises the UE category defined by the NR, the MIMO layer number, the modulation scheme and the like. The request message is always transmitted to the network side through the MN-side SRB, or if the UE configures the SN-side SRB3, the message may be transmitted to the network side through the MN-side SRB or through the SN-side SRB 3.

And 34-a.UE receives a reconfiguration message sent by a network side from SRB of the MN side, wherein the reconfiguration message comprises a reconfiguration message of the SN side, and the UE reconfigures the configuration of the SN side of the UE according to the reconfiguration message. If the reconfiguration message contains the reconfiguration message of the MN side at the same time, the UE reconfigures the configuration of the MN side at the same time. If the UE is successfully reconfigured, the UE sends a reconfiguration complete message to the network side, and the message is sent through the SRB of the MN side.

And 34-b.the UE receives a reconfiguration message sent by the network side from the SRB3 of the SN side, wherein the reconfiguration message comprises the reconfiguration message of the SN side, and the UE reconfigures the configuration of the SN side of the UE according to the reconfiguration message. If the UE is successfully reconfigured, the UE sends a reconfiguration complete message to the network side, and the message is sent through the SRB3 of the SN side.

And 35, when the UE detects that the overheating problem is relieved, applying for relieving the temporary UE capacity limitation to the network side to recover the UE capacity, wherein the flow is the same as the flow for applying for limiting the UE capacity by the UE side, and the UE can implicitly inform the network side to recover the UE capacity configuration by carrying the maximum category supported by the SN side of the UE or a special value agreed by the network side and the UE side in the request message or inform the network side to recover the UE capacity configuration by carrying an explicit identification in the request message.

Network side behavior:

41. if the network side MN receives a request message which is sent by UE and requests to limit the capability of the UE, and detects that the request message only carries reduced category of the SN side, the reduced category comprises the UE category defined by NR, MIMO layer number, modulation scheme and the like.

If the MN can successfully resolve the reduced category, the MN determines whether to accept the UE's request. If the MN accepts the request message of the UE, the MN sends the reduced category to the SN through an inter-network node interface message between the MN and the SN. And the SN reconfigures the configuration of the SN side of the UE according to the reduced category sent by the MN.

If the MN can not successfully resolve the reduced category, the reduced category is sent to the SN through an interface message between network nodes between the MN and the SN, and the SN determines whether to accept the request of the UE. If the SN accepts the request of the UE, the SN reconfigures the configuration of the SN side of the UE according to the reduced category sent by the UE.

42. If the network side SN receives a request message which is sent by the UE and requests to limit the capability of the UE through the SRB3, and detects that the request message only carries reduced category of the SN side, wherein the reduced category comprises the UE category defined by the NR, the MIMO layer number, the modulation scheme and the like. If the SN accepts the request of the UE, the SN reconfigures the UE according to the reduced category sent by the UE.

43. If the change of the UE configuration requires the SN to negotiate with the MN, the SN triggers the capability negotiation with the MN, and the negotiation result is decided by the MN. And the SN generates a reconfiguration message of the SN side, if the MN side also needs reconfiguration, the MN generates the reconfiguration message of the MN side, packages the reconfiguration message of the SN side and the reconfiguration message of the MN side together, and sends the reconfiguration message of the SN side and the reconfiguration message of the MN side to the UE through the SRB of the MN side. If the MN side does not need to be reconfigured, the SN generates a reconfiguration message of the SN side, the reconfiguration message is sent to the UE through the SRB of the MN side, or if the UE is configured with the SRB3 of the SN side, the reconfiguration message can be sent to the UE through the SRB of the MN side or can be sent to the UE through the SRB3 of the SN side.

And the MN receives a reconfiguration completion message sent by the UE, and if the reconfiguration completion message contains a reconfiguration completion message on the SN side, the reconfiguration completion message is sent to the SN through an interface message between the MN and the SN.

SN receives the reconfiguration complete message sent by UE.

45. If MN or SN receives the request message of request to limit UE ability sent by UE, the request message carries the maximum category supported by UE SN side or some special value agreed by network side and UE side to indicate UE side to request to restore UE ability implicitly, or the request message carries explicit identification to request network side to restore UE ability. The UE capability recovery procedure is the same as the UE capability restriction procedure.

And a third scenario and an EN-DC overheating scenario, wherein the UE independently reports the category of the MN side and the SN side to limit the UE capacity of the MN side and the SN side:

UE-side behavior:

and 51, the UE detects that the equipment is overheated and meets the condition that overheating triggers the request for reporting the limitation of the UE capacity, and the UE prepares to report a request message for requesting the limitation of the UE capacity.

And 52, the UE detects that the configuration of the MN side and the configuration of the SN side have the condition of triggering the request for limiting the UE capacity by reporting the overheating at the same time, namely that both the MN side and the SN side have the configurations of high-order MIMO, high-order CA or high-order modulation scheme and the like, the UE sends a request message for limiting the UE capacity to the network side, and the content of the request message comprises the configuration of limiting the MN side and the SN side of the UE.

53. according to the current SN side configuration and its own ability, the UE carries the recommended reduced category of SN side in the request message, the reduced category contains NR defined UE category and MIMO layer number and modulation scheme.

And 54, carrying the recommended reduced category of the MN side in the request message by the UE side according to the configuration and the self capability of the current MN side.

55. The request message is sent to the network side through the SRB of the MN side.

And 56-a.UE receives a reconfiguration message sent by a network side from an MN side, and if the reconfiguration message comprises a reconfiguration message of an SN side, the UE reconfigures the configuration of the SN side according to the reconfiguration message. If the message contains the reconfiguration message of the MN side, the UE reconfigures the configuration of the MN side at the same time. If the UE is successfully reconfigured, the UE sends a reconfiguration complete message to the network side, and the message is sent through the SRB of the MN side.

And 56-b.the UE receives the reconfiguration message sent by the network side from the SN side, and the UE reconfigures the configuration of the SN side of the UE according to the reconfiguration message. If the UE is successfully reconfigured, the UE sends a reconfiguration complete message to the network side, and the message is sent through the SRB3 of the SN side.

And 57, when the UE detects that the overheating problem is relieved, applying for relieving the temporary UE capacity limitation to the network side to recover the UE capacity, wherein the flow is the same as the flow for applying for limiting the temporary UE capacity at the UE side, and the UE can carry the maximum category supported by the MN side and the SN side of the UE or a special value agreed by the network side and the UE side in the request message to implicitly inform the network side to recover the UE capacity configuration or carry a certain explicit identification in the request message to inform the network side to recover the UE capacity configuration.

Network side behavior:

61. if the network side MN receives a request message which is sent by UE and requests to limit the capability of the UE, and detects that the request message carries reduced category of the SN side, the reduced category comprises the UE category defined by NR, MIMO layer number, modulation scheme and the like. The request message carries a reduced category at the MN side at the same time. The MN judges whether to accept the request which is sent by the UE and limits the configuration of the MN side.

If the MN can successfully resolve the reduced category of the SN side, the MN judges whether to accept the request of the UE for limiting the configuration of the SN side. If the MN accepts the request of UE to limit the configuration of the SN side, the MN sends the reduced category of the SN side to the SN through the network node interface message between the MN and the SN. And the SN reconfigures the configuration of the SN side of the UE according to the reduced category sent by the MN.

And 62-b, if the MN can not successfully analyze the reduced category on the SN side, sending the reduced category on the SN side to the SN through an interface message between network nodes between the MN and the SN, and determining whether to accept the request of limiting the configuration on the SN side by the UE or not by the SN. If the SN accepts the request of limiting the configuration of the SN side by the UE, the SN reconfigures the configuration of the SN side of the UE according to the reduced category sent by the UE.

63. the MN can decide the configuration of the MN side, the SN side decides the configuration of the SN side, if the change of the UE configuration requires the SN to negotiate with the MN, the SN negotiates with the MN for the capability and is finally decided by the MN. If the SN side needs to be reconfigured, the SN generates a reconfiguration message of the SN side, and if the MN side needs to be reconfigured, the MN generates a reconfiguration message of the MN side.

If the SN-side reconfiguration and the MN-side reconfiguration coexist, the SN-side reconfiguration message and the MN-side reconfiguration message are encapsulated together and transmitted to the UE through the MN-side SRB.

If only the MN side reconfiguration exists, the MN side reconfiguration message is sent to the UE through the MN side SRB.

If there is only the reconfiguration of the SN side, the reconfiguration message of the SN side is transmitted to the UE through the SRB of the MN side, or if the SRB3 of the SN side is configured, the message may be transmitted to the UE through the SRB3 of the SN side or may be transmitted to the UE through the SRB of the MN side.

And the 64-a.MN receives the reconfiguration completion message sent by the UE, and if the reconfiguration completion message contains the reconfiguration completion message at the SN side, the reconfiguration completion message is sent to the SN through an interface message between the MN and the SN.

And the SN receives a reconfiguration completion message sent by the UE.

65. If the MN receives a request message for limiting the UE capability, the request message carries the maximum category supported by the MN side and the SN side of the UE or a special value agreed by the network side and the UE side implicitly indicates that the UE side requests to recover the UE capability, or the request message carries an explicit identification to request the network side to recover the UE capability. The UE capability recovery procedure is the same as the UE capability restriction procedure.

And a fourth scenario, an overheating scenario of EN-DC, wherein the UE reports EN-DC category:

if an EN-DC category is defined, the category indicates in detail the maximum capability of the MN side and the SN side supported by the UE in the EN-DC scenario. The UE can report the EN-DC category to inform the network side of the UE capability in the EN-DC scene.

UE-side behavior:

71. the UE detects the device overheating and meets the condition that overheating triggers the request for reporting restriction UE capability, the UE prepares to report a request message requesting restriction UE capability.

And 72, the UE judges whether the configuration of only one side needs to be limited or the configuration of both sides needs to be limited simultaneously according to the configurations of the MN side and the SN side.

73. according to the current MN side and SN side configuration and its own ability, the UE carries the recommended reduced EN-DC category in the request message, or carries the recommended reduced EN-DC category and the indication mark for limiting the UE MN side and/or SN side configuration in the request message.

75. The request message is sent to the network side through the SRB of the MN side.

And 76-a.UE receives a reconfiguration message sent by the SRB of the MN side from the network side, and if the reconfiguration message contains the reconfiguration message of the SN side, the UE reconfigures the configuration of the SN side of the UE according to the reconfiguration message. And if the reconfiguration message contains the reconfiguration message of the MN side, the UE reconfigures the configuration of the MN side at the same time. If the UE is successfully reconfigured, the UE sends a reconfiguration complete message to the network side, and the message is sent through the SRB of the MN side.

And 76-b.UE receives a reconfiguration message sent by the network side from the SRB3 of the SN side, wherein the reconfiguration message carries the reconfiguration message of the SN side, the UE reconfigures the configuration of the SN side according to the reconfiguration message, and if the UE is successfully reconfigured, the UE sends the reconfiguration message to the network side, and the message is sent through the SRB3 of the SN side.

77. when detecting the overheat problem is removed, the UE applies for removing the temporary UE ability limitation to the network side and recovers the UE ability, the flow is the same as the flow of applying for limiting the temporary UE ability at the UE side, the UE can carry the maximum EN-DC category supported by the UE or a special value agreed by the network side and the UE side in the request message to implicitly inform the network side to recover the UE ability configuration or carry a dominant mark in the request message to inform the network side to recover the UE ability configuration.

Behavior on the network side:

81. if the network side MN receives a request message which is sent by the UE and requests to limit the capability of the UE, the request message is detected to carry reduced EN-DC category, or the request message carries reduced EN-DC category and an indication mark for limiting the configuration of the MN side and/or the SN side of the UE. And the MN judges whether to accept the request for limiting the UE capability sent by the UE.

82-a. if the request message carries only reduced EN-DC category, the MN determines whether to accept the UE's request. If the MN accepts the request of the UE, the MN sends the reduced EN-DC category to the SN through an interface between the MN and the SN. And the SN reconfigures the configuration of the SN side of the UE according to the reduced EN-DC category sent by the MN. And the MN reconfigures the configuration of the MN side of the UE according to the reduced EN-DC category.

If the request message carries reduced EN-DC category and indication mark for limiting UE MN side and/or SN side configuration, MN judges whether to accept the request.

If the indication indicates that only the MN side configuration needs to be restricted, the MN reconfigures the UE MN side configuration according to the reduced EN-DC category sent by the UE.

If the indication indicates that only configuration on the SN side needs to be restricted, the MN sends the reduced EN-DC category to the SN via an inter-network node interface message between the MN and the SN. And the SN reconfigures the configuration of the SN side of the UE according to the reduced EN-DC category sent by the MN.

If the indication indicates that the MN side and SN side configuration need to be restricted, the MN decides on a reconfiguration message for the MN side. The MN sends the reduced EN-DC category to the SN through an interface between the MN and the SN. And the SN reconfigures the configuration of the SN side of the UE according to the reduced EN-DC category sent by the MN.

The MN can decide the configuration of the MN side, the SN side decides the configuration of the SN side, and if the change of the UE configuration requires the SN to negotiate with the MN, the SN negotiates the capability with the MN and is finally decided by the MN. The SN generates a reconfiguration message of the SN side of the UE, and the MN generates a reconfiguration message of the MN side of the UE.
