In the embodiment of the present application, the "protocol" may refer to a standard protocol in the field of communications, and for example, the "protocol" may include an LTE protocol, an NR protocol, and a related protocol applied in a future communication system, which is not limited in this application.

For better understanding of the embodiments of the present application, the dual connection related to the present application will be described.

After being configured with dual connectivity, the terminal device can simultaneously perform data transmission with a Master Node (MN) and a Secondary Node (SN), thereby improving transmission efficiency. Dual connectivity is a mode of operation when the terminal device is in a connected state, in which the network device configures the terminal device with a Master Cell Group (MCG) and a Secondary Cell Group (SCG), wherein a set of serving cells associated with the MN, called MCG, and a set of serving cells associated with the SN, called SCG.

When the terminal device is already in the dual connectivity operation mode, there are several methods for releasing the SN:

mode 1, a network device initiates a release SN flow. As shown in fig. 2, the MN sends a reconfiguration message to the UE releasing the SN; and the UE sends a reconfiguration message completion for releasing the SN to the MN so as to release the connection with the SN.

And in the mode 2, the terminal equipment reports the SCG failure message to the network side and triggers the network side to release the SN.

In the event of SCG failure, the terminal device will maintain the current measurement configuration control (from the MN and SN), and will continue to make measurements if possible. Through the measurement configuration of the SN configured by the MN, the terminal equipment can continue to report the measurement result after the SCG fails. The terminal device sends the available measurement results to the MN via an SCG failure message, and the MN decides the next action on the SN according to this message, possibly holding the SN, or changing the SN, or releasing the SN, as shown in fig. 3.

In the mode 3, the terminal device triggers a Radio Resource Control (RRC) reestablishment procedure of the MCG, so as to release the connection with the SCG.

And 4, the terminal equipment reports the A2 event of the SCG side and triggers the network side to release the SN.

Mode 5, 5G is closed via the user interface.

The above mode 1 is that the network triggers the release of SCG, and the UE cannot actively release SCG.

The above mode 2 is a processing mode for SCG failure, and after receiving the SCG failure message, the network node may not necessarily select to release the SN, and may continue to maintain the current SN or select to change the SN.

The above-mentioned mode 3 is a processing mode of MCG failure, and SCG can be released. Some manufacturers have adopted this method to release SCG, for example: after the network configures the dual connectivity, when the terminal considers that the terminal does not need the SCG (it is not that the MCG connection is really abnormal), the terminal actively triggers the RRC reestablishment procedure, thereby releasing the SCG. The disadvantages of this approach: the RRC reestablishment process needs to inform the network of the reason for reestablishment in the reestablishment message, where the reason for reestablishment includes Radio Link failure/Radio Link Control (RLC) retransmission times reaching the maximum, which generally indicates that a problem occurs in the underlying Link, and if the MCG is in normal service, the terminal sends the RRC reestablishment process to the network node, and the reporting of the reasons to the network is misleading to the network side, which affects the key performance index of the network device, and is not favorable for subsequent scheduling of the network. In addition, the re-establishment procedure may also cause interruption of service delivery. Finally, after the reestablishment process is successful, the network may also add the SN to the terminal again.

In the above mode 4, when the cell signal quality of the SCG is lower than a certain threshold, an event at the SCG side A2 is reported to the network, so as to trigger the network side to release the SN. The disadvantage of the method 4 is the same as that of the method 3, and if the terminal intentionally reports A2 to the network at the SCG side to trigger SN release, the misleading is caused to the network side, which affects the key performance index of the network device and is not beneficial to the subsequent scheduling of the network.

In the above mode 5, turning off the 5G triggers a Tracking Area Update (TAU) procedure, or a detach (detach) procedure followed by an attach (attach) procedure. In this process, the traffic of the intermediate terminal is interrupted.

The research shows that when the terminal device is in the Dual-connection working mode, 2 network nodes (MN and SN) need to be monitored and measured simultaneously, if the terminal device is in the Multi-RAT Dual-connection (MR-DC), 2 network systems need to be monitored simultaneously, taking EN-DC (LTE NR DC) as an example, MCG is an Evolved Universal Radio Access (E-UTRA) cell, and an NR cell during SCG, so that the power consumption of the terminal device in the Dual-connection working mode is large, and some 5G base bands adopt the plug-in mode, so that the power consumption is relatively large and the heat generation is more serious. While dual connectivity brings high rates, it brings some adverse effects at the terminal: increased temperature, increased power consumption, etc. The schemes for releasing the SN described in the above modes 1 to 5 are triggered by the network side, and the terminal side has no autonomy, which is not favorable for the terminal device to control the dual connectivity.

Based on the above problem, the present application provides a scheme for a terminal device to actively trigger and release a part of wireless connections held by the terminal device, which can eliminate or reduce adverse effects caused by dual connections directly or indirectly.

The technical solution of the present application is detailed below by specific examples.

Or, the network device may determine, based on the connection release reason, whether to send measurement configuration information to the terminal device after the timer expires, where the measurement configuration information is used to trigger an addition procedure of the wireless connection.

Optionally, in some embodiments, the terminal device may be triggered to send the first information by some abnormal event or a specific event. The scheme for the terminal device to send the first information is detailed below by examples 1 to 3.

Example 1, in a case that the temperature of the terminal device is greater than a first threshold, or in a case that a temperature change rate of the terminal device within a first time period is greater than a second threshold, the terminal device sends the first information, and the connection release reason is that the temperature of the terminal device is too high.

That is, an abnormal event that may be caused by the temperature of the terminal device triggers the terminal device to transmit the first information.

Note that the temperature of the terminal device may be detected by a temperature sensor.

Optionally, the first threshold may be configured by the network device, or the first threshold is determined by the terminal device (in this case, the terminal device needs to report the first threshold to the network device), or the first threshold is preconfigured or agreed by a protocol.

Optionally, the second threshold may be configured by the network device, or the second threshold is determined by the terminal device (in this case, the terminal device needs to report the second threshold to the network device), or the second threshold is preconfigured or agreed by the protocol.

It should be noted that the temperature change rate of the terminal device in the first time period can be represented by a slope k of the temperature change in the first time period. For example, as shown in table 1, at time t1, the temperature of the terminal device is TEMP1; at time t2, the temperature of the terminal equipment is TEMP2; at time t3, the temperature of the terminal equipment is TEMP3; at time t4, the temperature of the terminal equipment is TEMP4; at time t5, the temperature of the terminal equipment is TEMP5; at time t6, the temperature of the terminal device is TEMP6. The rate of temperature change k = (TEMP 2-TEMP 1)/(t 2-t 1) of the terminal device for the time period t1 to t 2.

Optionally, in example 1, the network device starts the timer after receiving the first information, and does not add a wireless connection to the terminal device during the timer running.

Optionally, in example 1, in a case that the timer expires, the network device sends measurement configuration information to the terminal device, where the measurement configuration information is used to trigger an addition procedure of the wireless connection.

The specific flows S11-S16 of example 1 can be seen in fig. 5, assuming that the terminal device is in dual connectivity mode.

S11, establishing double connection between the terminal equipment and the network equipment;

s12, the temperature of the terminal equipment is too high, for example, the temperature of the terminal equipment is greater than a first threshold, or the temperature change rate of the terminal equipment is greater than a second threshold in a first time period;

s13, the terminal equipment sends SN release request information to the network equipment, wherein the SN release request information at least comprises relevant information (time information) of Timer1 and overhigh temperature (connection release reason) of the terminal equipment;

s14, after receiving the SN release request information, the network equipment sends RRC reconfiguration information to the terminal equipment, wherein the RRC reconfiguration information is used for indicating the release of the connection between the terminal equipment and the SCG;

s15, the network equipment starts a Timer (Timer) 1, and does not add SCG connection to the terminal equipment during the running period of the Timer 1;

and S16, after the time 1 is overtime, the network equipment sends measurement configuration information to the terminal equipment, and the measurement configuration information is used for triggering the subsequent SN adding process.

That is, in case the temperature of the terminal device is too high, the terminal in the dual connection operation mode can control the release of the SCG connection by itself. Through this kind of mode, when guaranteeing that terminal equipment's service can normally go on, can alleviate terminal organism temperature rising trend, prevent the damage of high temperature to the terminal organism, promote user experience.

Example 2, in a case that the battery power of the terminal device is lower than the third threshold, or in a case that the battery power of the terminal device is lower than the third threshold and the power saving mode is triggered to be turned on, the terminal device sends the first information, and the connection release reason is that the battery power of the terminal device is insufficient.

That is, the terminal device may be triggered to transmit the first information by a specific event caused by the battery level of the terminal device.

Optionally, the third threshold may be configured by the network device, or the third threshold is determined by the terminal device (in this case, the terminal device needs to report the third threshold to the network device), or the third threshold is preconfigured or agreed by a protocol.

For example, assuming that the terminal device is in the dual connectivity mode, when the battery power level of the terminal device is lower than the third threshold, the user may be prompted by a prompt box whether to start the power saving mode, and if the user selects yes, the terminal device sends SN release request information to the network device, as shown in fig. 6.

Optionally, in example 2, the network device starts the timer after receiving the first information, and does not add a wireless connection to the terminal device during running of the timer.

Optionally, in example 2, in a case that the timer expires, the network device sends measurement configuration information to the terminal device, where the measurement configuration information is used to trigger an addition procedure of the radio connection.

Optionally, in example 2, in a case where the timer times out and the battery power of the terminal device is not lower than a third threshold, or in a case where the timer times out and the power saving mode is turned off, the network device sends measurement configuration information to the terminal device, where the measurement configuration information is used to trigger an addition procedure of the wireless connection.

The specific flows S21-S26 of example 2 can be seen in fig. 7, assuming that the terminal device is in dual connectivity mode.

S21, establishing double connection between the terminal equipment and the network equipment;

s22, the battery power of the terminal device is insufficient, for example, the battery power of the terminal device is lower than a third threshold, or the battery power of the terminal device is lower than the third threshold and the power saving mode is triggered to be turned on;

s23, the terminal equipment sends SN release request information to the network equipment, wherein the SN release request information at least comprises relevant information (time information) of Timer2 and insufficient battery power (connection release reason) of the terminal equipment;

s24, after receiving the SN release request information, the network device sends RRC reconfiguration information to the terminal device, where the RRC reconfiguration information is used to instruct to release the connection between the terminal device and the SCG;

s25, the network equipment starts the Timer2, and does not add SCG connection to the terminal equipment during the running period of the Timer 2;

and S26, after the Timer2 is overtime, the network equipment sends measurement configuration information to the terminal equipment, and the measurement configuration information is used for triggering the subsequent SN adding process.

That is, the terminal in the dual connection operation mode can autonomously control the release of the SCG connection in case the battery power of the terminal device is insufficient. By the method, the power consumption of the terminal equipment can be reduced, the standby time of the terminal equipment is prolonged and the user experience is improved while the service of the terminal equipment can be normally carried out.

Example 3, the terminal device sends the first information in case there is voice traffic on the first wireless connection and the Reference Signal Received Power (RSRP) of the serving cell measured by the terminal device is less than a fourth threshold and/or the Reference Signal Received Quality (RSRQ) of the serving cell measured by the terminal device is less than a fifth threshold, and the connection release reason is guaranteed by the voice traffic on the first wireless connection.

That is, the terminal device may be triggered to transmit the first information by a specific event caused by a voice service of the terminal device. In this case, the first information may not include time information.

Optionally, the fourth threshold may be configured by the network device, or the fourth threshold is determined by the terminal device (in this case, the terminal device needs to report the fourth threshold to the network device), or the fourth threshold is preconfigured or agreed by a protocol.

Optionally, the fifth threshold may be configured by the network device, or the fifth threshold is determined by the terminal device (in this case, the terminal device needs to report the fifth threshold to the network device), or the fifth threshold is preconfigured or agreed by a protocol.

It should be noted that, in the EN-DC dual connectivity mode, there is a scenario in which data transmission and VoLTE are concurrent, as shown in fig. 8, the maximum uplink power is limited to 20dB, which is 3dB lower than the uplink loss of the conventional 4G voice, and thus the edge user experience is affected. If the SCG connection is conditionally deleted while the VoLTE occurs, a gain of about 3dB is generated on the LTE of the terminal, and the voice call quality of the VoLTE under a weak coverage scene is favorably ensured. Therefore, when VoLTE occurs in a weak coverage scenario, the terminal device may actively send SN release request information to the network device. And under the condition that the RSRP of the serving cell measured by the terminal equipment is smaller than a fourth threshold and/or the RSRQ of the serving cell measured by the terminal equipment is smaller than a fifth threshold, the terminal equipment is in a weak coverage mode, and at the moment, the terminal equipment actively sends SN release request information to the network equipment.

Optionally, in example 3, the network device does not add a wireless connection to the terminal device until the voice service is over.

Optionally, in example 3, after the voice service is ended, the network device may send measurement configuration information to the terminal device, where the measurement configuration information is used to trigger an addition procedure of the wireless connection.

The specific flows S31-S36 of example 3 can be seen in fig. 9, assuming that the terminal device is in dual connectivity mode.

S31, establishing double connection between the terminal equipment and the network equipment;

s32, the terminal device performs VoLTE call based on MCG connection and performs data transmission based on SCG connection, for example, as shown in fig. 8;

s33, triggering a VoLTE call guarantee, for example, RSRP of the serving cell measured by the terminal device is smaller than a fourth threshold and/or RSRQ of the serving cell measured by the terminal device is smaller than a fifth threshold;

s34, the terminal device sends SN release request information to the network device, wherein the SN release request information at least comprises VoLTE call guarantee (connection release reason);

s35, after receiving the SN release request information, the network device sends RRC reconfiguration information to the terminal device, where the RRC reconfiguration information is used to instruct to release the connection between the terminal device and the SCG;

and S36, after the VoLTE call is finished, the network equipment sends measurement configuration information to the terminal equipment, wherein the measurement configuration information is used for triggering a subsequent SN adding process.

That is, in the case where it is necessary to guarantee VoLTE call over MCG connection, the terminal in the dual connection operation mode can control the release of SCG connection by itself. By the method, the service of the terminal equipment can be normally carried out, the VoLTE call quality under the weak coverage mode is favorably improved, and the user experience is improved.

Therefore, in the embodiment of the present application, the terminal device can trigger to release at least one wireless connection other than the first wireless connection in the plurality of wireless connections that the terminal device holds, and since the terminal device also holds at least the first wireless connection, normal service of the terminal device can be ensured. Therefore, the user experience can be improved under the condition that the reason for releasing the connection triggers the terminal equipment to release at least one wireless connection kept by the terminal equipment. For example, under the condition that the connection release reason is that the temperature of the terminal device is too high, the terminal device triggers and releases at least one wireless connection except the first wireless connection in a plurality of wireless connections kept by the terminal device, so that the service of the terminal device can be normally performed, the temperature rising trend of the terminal body can be relieved, the damage to the terminal body caused by the too high temperature can be prevented, and the user experience can be improved. For another example, when the reason for releasing the connection is that the battery power of the terminal device is insufficient, the terminal device triggers to release at least one wireless connection other than the first wireless connection in the plurality of wireless connections that the terminal device maintains, so that the service of the terminal device can be performed normally, the power consumption of the terminal device can be reduced, the standby time of the terminal device can be increased, and the user experience can be improved. For another example, when the connection release reason is that the voice service on the first wireless connection needs to be ensured, the terminal device triggers to release at least one wireless connection, except the first wireless connection, of the multiple wireless connections that the terminal device maintains, so that the service of the terminal device can be ensured to be performed normally, and the voice call quality in the weak coverage mode is facilitated to be improved, and the user experience is improved.
