The base station may support networks with the same or different access technologies. The embodiments of the present application do not limit the specific technology and specific device form adopted by the network equipment.

[0038] A base station can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move according to the location of the mobile base station. In other examples, a helicopter or drone can be configured to act as a device that communicates with another base station.

[0039] In some deployments, the network device may refer to a CU or a DU; or, the network device includes a CU and a DU. Optionally, the gNB may include an AAU.

[0040] The network equipment and terminal equipment can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on the water surface; they can also be deployed on aircraft, balloons and satellites in the air. The embodiments of the present application do not limit the scenarios in which the network equipment and terminal equipment are located.

[0041] In Release 17 (R17) of 3GPP, multi-card technology is introduced, that is, a terminal device can be installed with two subscriber identity modules (SIM) cards, so that it can work in two networks, and there is no interaction process between the two networks. Due to the limited hardware capabilities of the terminal device, the terminal device only works in one of the networks at the same time. For example, the terminal device can work in the network provided by the first network device and the second network device. At the same time, the terminal device either works in the network of the first network device or in the network of the second network device, but cannot work in the network of the first network device and the network of the second network device at the same time. In other words, at the same time, the terminal device can transmit data with one of the first network device and the second network device, but cannot transmit data with the first network device and the second network device at the same time. In the embodiment of the present application, the first network device and the second network device are network devices of different operators, and there is no interface between the first network device and the second network device.

[0042] Assume that the terminal device is in a radio resource control (RRC) connection state (RRC CONNECT) in the network provided by the first network device, and is in an RRC idle state (IDLE) or an inactive state (INACTIVE) in the network provided by the second network device. At this time, the terminal device needs to periodically receive paging messages from the second network device, so the first network device needs to configure a time interval (GAP) for the terminal device to receive paging messages from the second network device. During the GAP period, the first network device does not transmit data with the terminal device. However, the specific moment of the paging occasion (PO) for transmitting paging messages between the terminal device and the second network device is only known to the terminal device and the second network device, and the first network device does not know it. Therefore, the terminal device needs to notify the first network device of the GAP information, and then the first network configures the corresponding GAP for the terminal device.

[0043] GAP can be divided into two categories, namely periodic GAP and non-periodic GAP. Periodic GAP occurs periodically; non-periodic GAP occurs only once, and its start time is requested by the terminal device and configured by the first network device, and the end time is not configured. After the terminal device completes the task in the second network, it returns to the first network to establish an RRC connection. Since PO occurs periodically, the first network device usually configures a periodic GAP for the terminal device to monitor the paging message sent by the second network device.

[0044] As an example, Figure 2 The working process of the terminal device in the dual-SIM scenario is shown, wherein in step 110, the terminal device performs data transmission with the first network device.

[0045] In step 120, the terminal device sends a GAP request to the first network device.

[0046] In step 130, the first network device configures a GAP for the terminal device.

[0047] If the first network device configures a periodic GAP for the terminal device, then execute steps 140 to 160 ; if the first network device configures an aperiodic GAP for the terminal device, then execute step 170 .

[0048] In step 140, the terminal device monitors the paging message based on the periodic GAP.

[0049] It can be understood that, in addition to monitoring paging messages, the periodic GAP may also have other functions, such as measurement of inter-frequency cells.

[0050] In step 150, data is transmitted between the terminal device and the first network device.

[0051] In step 160, the terminal device monitors the paging message based on the periodic GAP.

[0052] In step 170, the terminal device monitors the paging message based on the aperiodic GAP.

[0053] Alternatively, when the second network device has service data to be sent, the terminal device may receive the service data based on the non-periodic GAP.

[0054] In Release 19 (R19) of 3GPP, a power saving mode terminal device was introduced. This terminal device has two independent receivers, namely the main receiver (MR) and the low power receiver (LR). Among them, LR can work when the wireless signal is higher than the threshold, and its working power is lower. MR corresponds to the original receiver, and its working power is higher than LR, and it can work when the wireless signal is lower than the threshold. The working modes of this type of terminal device in IDLE state and INACTIVE state can be referred to Figure 3 .

[0055] As an example, Figure 3 As shown, if the terminal device is in the edge area of ​​the cell, that is, Figure 3 In the gray area shown in , the strength or quality of the wireless signal is lower than the second threshold, and the terminal device monitors the paging message through the MR on the PO, such as Figure 3 If the terminal device is in the center area of ​​the cell, that is, Figure 3 The white area shown in the figure has a wireless signal strength or quality higher than the first threshold. At this time, the terminal device can monitor the paging notification through the LR at the time position before the PO. The paging notification is used to indicate that there is a paging message for the terminal device on the subsequent PO. Among them, if a paging message is to be transmitted, the network device will issue a paging notification within the LR working time to indicate that a paging message is to be transmitted. If the terminal device receives the paging notification through the LR, the terminal device monitors the paging message through the MR on the subsequent PO. Otherwise, the terminal device does not start the MR. Figure 3 As shown in (b) in FIG. 1 , since most of the PO opportunities, for example, about 98% of the POs, do not have paging messages for the terminal device, the paging message is adopted. Figure 3 In the manner shown, the terminal device can reduce the number of times the MR is started, thereby achieving the purpose of saving the power consumption of the terminal device.

[0056] In the current multi-card scenario, only terminal devices configured with MR are considered, and terminal devices configured with LR in power saving mode are not considered. If a terminal device configured with LR in power saving mode works in a multi-card scenario, the terminal device applies for GAP to the first network device in order to monitor the paging message of the second network device, and periodically monitors the paging message sent by the second network device through MR, and the probability of not monitoring the paging message sent by the second network device is high, which is unnecessary. For this reason, in an embodiment of the present application, in some cases, for example, the terminal device is in the central area of ​​the cell in the second network provided by the second network device, and its signal strength or quality is higher than the first threshold, such terminal devices can monitor the paging notification sent by the second network device before PO through LR, and transmit data with the first network device through MR, and receive the paging message through MR only when the paging notification is monitored through LR, thereby greatly reducing the GAP duration of stopping data transmission between the terminal device and the first network device, and improving the data transmission rate between the terminal device and the first network device per unit time.

[0057] Figure 4 A schematic flow chart of a communication method according to an embodiment of the present application is shown. Figure 4 The method 200 shown may be performed by a terminal device and a first network device, wherein the terminal device supports dual SIM cards, i.e., two SIM cards, and can work in networks of two different operators, such as networks provided by the first network device and the second network device of different operators.

[0058] like Figure 4 As shown, method 200 may include some or all of the following steps.

[0059] In step 210, the terminal device sends a first request message to the first network device.

[0060] Accordingly, in step 220, the first network device receives the first request message sent by the terminal device.

[0061] The first request message is used to request the first network device to configure the first time interval, or to apply for the first time interval from the first network device. The first request message is carried in RRC signaling, such as UE assistance information.

[0062] In an embodiment of the present application, the terminal device includes an LR and an MR, the LR is used to monitor the paging notification sent by the second network device, the paging notification is used to indicate that there is a paging message sent by the second network device on the subsequent PO, and the MR is used to receive the paging message within a first time interval.

[0063] In the case where the terminal device includes MR and LR and supports dual cards, the terminal device can apply to the first network device to configure the first time interval, so that the terminal device monitors the paging notification sent by the second network device based on the LR, and when the terminal device monitors that the paging notification indicates that there is a paging message sent by the second network device to the terminal device on the PO after it, it stops the data transmission between the first network device and the first network device within the first time interval and uses the MR to receive the paging message sent by the second network device. Based on the collaborative work of LR and MR, the paging notification is monitored by the LR, and the paging message is received by the MR when the paging message is monitored, which reduces the power consumption of the terminal device, and increases the duration of data transmission between the terminal device and the first network device through the MR, reduces the impact on the data transmission between the terminal device and the first network device, increases the data transmission volume, and improves the throughput.

[0064] The terminal device can send a first request message to the first network device at any time to instruct the first network device to configure a first time interval for it. For example, the terminal device can request the first network device to configure the first time interval during initial access, so that when the paging notification is subsequently monitored through the LR, the paging message is received through the MR within the first time interval.

[0065] Optionally, the first request message may include time-related information of the paging message, so that the first network device can receive the paging message within the first time interval configured. For example, the time-related information of the paging message includes one or more of the following: a system frame number (SFN) corresponding to the paging message, an offset value corresponding to the paging message, and a duration corresponding to the paging message.

[0066] As an example, assuming that there are paging messages at positions such as SFN=0, 128, 256, the first request message can carry information of SFN=0, SFN=128, SFN=256; assuming that there are paging messages at positions such as SFN=1, SFN=129, SFN=257, the first request message can also carry information with an offset value of 1; assuming that the time to measure the wireless signal of the second network device and the time to monitor the paging message require 5ms, the first request message can also carry 5ms of information.

[0067] Optionally, the first request message may also include the reason why the terminal device requests to configure the first time interval. Since the terminal device may apply to the first device for configuring the time interval based on a variety of reasons, carrying the reason for requesting to configure the first time interval in the first request message is helpful for the network device to determine how to configure a suitable time interval for the terminal device. The reason why the terminal device requests to configure the first time interval includes, for example, capability information of the terminal device, and the capability information includes, for example, that the terminal device supports MR and LR and supports dual SIM cards.

[0068] In some implementations, the method 200 may further include, the terminal device receiving configuration completion information of the first time interval sent by the first network device. Accordingly, the configuration completion information may also include the reason why the first network device configures the first time interval. The reason why the first network device configures the first time interval, for example, includes capability information of the terminal device, and the capability information, for example, includes that the terminal device supports MR and LR and supports dual SIM cards.

[0069] In some implementations, the first time interval is a semi-static time interval. That is, after the first time interval is configured, it is activated based on the request of the terminal device. The activation described here can also be called starting or taking effect. At this time, when the LR monitors the paging notification, such as Figure 5 As shown, method 200 may further include step 230 and step 240 .

[0070] In step 230, the terminal device sends a second request message to the first network device.

[0071] Correspondingly, in step 240, the first network device receives the second request message sent by the terminal device.

[0072] The second request message is used to instruct the first network device to activate the first time interval, and the MR is used to receive a paging message sent by the second network device within the activated first time interval.

[0073] The second request message is carried, for example, in a media access control control element (MAC CE), or in a physical uplink control channel (PUCCH), such as a specific notification on the PUCCH.

[0074] If the first time interval is a semi-static time interval, it is assumed that the current terminal device is in an idle state or an inactive state in the network provided by the second network device, and is in a connected state in the network provided by the first network. At this time, the terminal device interacts with the first network device through the MR, and monitors the paging notification sent by the second network device through the LR. When the terminal device detects that the paging notification indicates that there is a paging message sent by the second network device to the terminal device on the corresponding PO, the terminal device sends a second request message to the first network device to instruct the first network device to activate the first time interval, so as to receive the paging message through the MR within the activated first time interval.

[0075] In the related art, the terminal device requests the first network device to configure a periodic GAP or aperiodic GAP through RRC signaling, and the configuration takes effect immediately without activation or deactivation operations. In an embodiment of the present application, if the LR of the terminal device receives a paging notification sent by the second network device, and then applies to the first network device for a non-periodic GAP through an RRC message, and the first network device then configures a non-periodic GAP for the terminal device through RRC signaling, then the process takes a long time and may not meet the time interval requirement between the paging notification sent by the second network device and the PO indicated by it, so that the terminal device does not have time to receive the paging message. If the terminal device applies to the first network device for a periodic GAP through RRC signaling, the first network device configures a periodic GAP for the terminal device through RRC signaling and the periodic GAP takes effect immediately, that is, regardless of whether the LR of the terminal device receives a paging notification in the second network device, the periodic GAP between the terminal device and the first network device is valid. Obviously, this is unreasonable because the probability that the LR of the terminal device receives a paging notification is not high.

[0076] In this embodiment, the terminal device requests the first network device to configure a semi-static first time interval, and when the LR of the terminal device listens to the paging notification, it requests to activate the first time interval through a second request message carried on the MAC CE or PUCCH, so that the first time interval can be used more quickly to receive the paging message through the MR.

[0077] For the listening time of the paging notification, if the LR of the terminal device does not listen to the paging notification during the listening time, the terminal device does not notify the first network device, that is, does not send the second request message, and the first network device and the terminal device can perform data transmission within the first time interval; if the LR of the terminal device listens to the paging notification during the listening time, the terminal device notifies the first network device and sends the second request message to the first network device to request activation of the first time interval. When the first network device receives the second request message, it may not perform data transmission with the terminal device within the first time interval after the activation moment, and the terminal device receives the paging message sent by the second network device through the MR within the first time interval.

[0078] In this case, when configuring the first time interval, the first request message may also carry indication information for indicating that the first time interval is semi-static. In this way, the first network device may assume that the first time interval will not take effect immediately after configuration, and will take effect only when the terminal device requires it to take effect.

[0079] In some implementations, the first time interval is a periodically configured time interval, that is, the first time interval includes multiple periodic time windows, wherein the second request message is used to activate part or all of the time windows in the first time interval.

[0080] The time windows activated in the first time interval may be determined based on one or more of the following, for example: the position of the first activated time window; the number of activated time windows.

[0081] The position of the time window in the first time interval corresponds to the position of the PO. Since the paging notification can indicate whether there is a paging message on the first PO after it, or whether there is a paging message on the Nth PO after it, where N is a positive integer greater than 1, the position of the first activated time window in the first time interval can be the first time window or the Nth time window after the first network device receives the second request message. N can be agreed upon by the protocol or configured by the network, for example.

[0082] Specifically, the first network device may not transmit data with the terminal device in the next time window after receiving the second request message, so that the terminal device can receive the paging message sent by the second network device through MR in the next time window; or, the first network device may not transmit data with the terminal device in the Nth time window after receiving the first request message, so that the terminal device can receive the paging message sent by the second network device through MR in the Nth time window.

[0083] The terminal device may activate one or more time windows in the first time interval through the second request message. If the MR of the terminal device can successfully receive the paging message of the second network device once, it may only activate one of the time windows, that is, request the first network device not to transmit data with it within a time window. At this time, if the MR fails to successfully receive the paging message sent by the second network device once, it may request the first network device to activate the first time interval again.

[0084] Generally, the network device may also send paging messages in a plurality of consecutive POs, so the terminal device may also request the first network device not to transmit data with it in M ​​time windows, M>1. In this way, the terminal device may not transmit data with the first network device in M ​​consecutive time windows, but listen to the paging messages sent by the second network device. M may be agreed upon by the protocol or configured by the network, for example.

[0085] Optionally, information about the time windows activated in the first time interval, such as the position of the first activated time window and the number of activated time windows, may be carried in the second request information and / or indicated by the first network device.

[0086] In other implementations, the second request message may not carry the number of activated time windows. In this case, the terminal device may send a deactivation request to the first network device after correctly receiving the paging message of the second network device, so as to instruct the first network device to deactivate the first time interval, thereby resuming data transmission with the terminal device. In other words, the number of activated time windows in the first time interval is determined by the activation indication and deactivation indication of the terminal device.

[0087] In the embodiment of the present application, how to activate the first time interval can be determined based on the quality of the wireless signal of the second network device. The quality of the wireless signal described below can also be replaced by related parameters such as the strength of the wireless signal.

[0088] For example, the quality of the wireless signal of the second network device is higher than the first threshold value, the terminal device monitors the paging notification through the LR, and sends a second request message to the first network device when the paging notification is monitored to activate the first time interval, and does not transmit data with the first network device during the activated first time interval, but monitors the paging message sent by the second network device. The first threshold value is notified to the terminal device by the second network device, for example, carried in the system information of the second network device. At this time, the partial time window in the first time interval can be activated by the aforementioned various methods.

[0089] For another example, the quality of the wireless signal of the second network device is lower than the second threshold, and the terminal device cannot monitor the paging notification through the LR, that is, it no longer uses the working mode of "LR monitoring paging notification + MR receiving paging message", but switches to monitoring the paging message at each PO through the MR. Among them, the second threshold is, for example, notified to the terminal device by the second network device, such as carried in the system information of the second network device. In this case, optionally, the terminal device can send a second request message to the first network device, and request to continuously enable the first time interval, or instruct the first network device to reconfigure the first time interval as a semi-static time interval through another request message such as a third request message. After receiving the second request message, the first network device considers that the working mode of the first time interval is equivalent to the periodic GAP in the related technology, that is, the first network device does not transmit data with the terminal device in each time window in the first time interval, and the terminal device monitors the paging message sent by the second network device on the PO through the MR in each time window in the first time interval.

[0090] If the quality of the wireless signal of the second network device subsequently reaches or exceeds the first threshold, the working mode of "LR monitoring paging notification + MR receiving paging message" can be used again, and the terminal device can instruct the first network device to restore the semi-static working mode of the first time interval through the corresponding indication information. After receiving the indication information, the first network device believes that the terminal device will not use MR to receive the paging message sent by the second network device in the first time interval. As long as the terminal device does not notify the first network device to activate the first time interval through the second request message, the first network device can transmit data with the terminal device lower than the first time interval.

[0091] The terminal device may, for example, notify the first network device to continuously enable the first time interval through MAC CE, specific notification on PUCCH, etc.; or may notify the first network device to continuously enable the first time interval through RRC signaling such as auxiliary information.

[0092] In other implementations, the first time interval may be one of multiple time intervals configured by the first network device for the terminal device, wherein the multiple time intervals may have different identifiers, such as GAP IDs.

[0093] If the terminal device applies to the first network device for configuring a set of time intervals, namely the first time interval, the first network device can configure only the first time interval for the terminal device. In this way, the terminal device only needs to send a second request message to the first network device to instruct the first network device to activate the first time interval.

[0094] If the terminal device applies to the first network device for configuring multiple sets of time intervals, the first network device can configure multiple sets of time intervals for the terminal device. At this time, the second request message sent by the terminal device to the first network device needs to carry identification information to indicate which set of time intervals the first network device activates. In addition, if multiple sets of semi-static time intervals are configured, in the case where the time interval needs to be enabled continuously, the second request message also needs to carry identification information to notify the first network device which set of time intervals are enabled continuously.

[0095] When the first network device is configured with two or more sets of time intervals, the types of the multiple sets of time intervals can be the same, for example, they are all semi-static time intervals, or the types of the multiple sets of time intervals can be different, for example, respectively configuring semi-static time intervals and statically configured periodic GAPs in related technologies.

[0096] For example, the first network device configures two sets of time intervals for the terminal device, namely the first time interval and the second time interval. Among them, the first time interval is a semi-static time interval, that is, the terminal device determines whether to activate the first time interval according to whether the LR monitors the paging notification; the second time interval is a periodic GAP in the relevant technology, that is, the terminal device periodically monitors the paging message on the PO through the MR or performs other operations such as the measurement of the heterofrequency cell. At this time, the activation of the set of time intervals can be determined according to the quality of the wireless signal of the second network device. If the quality of the current wireless signal of the second network device is greater than the first threshold, for example, the terminal device is currently in the central area of ​​the cell, the terminal device can instruct the first network device to activate the first time interval; if the quality of the current wireless signal of the second network device is less than the second threshold, for example, the terminal device is currently in the edge area of ​​the cell, the terminal device can no longer use the LR to monitor the paging notification, but needs to monitor the paging message through the MR, then the terminal device can instruct the first network device to activate the second time interval, so as to monitor the paging message through the MR in each time window in the second time interval.

[0097] Optionally, the quality of the wireless signal of the second network device may be obtained in one or more of the following ways: measurement by the terminal device; prediction by the terminal device based on artificial intelligence (AI).

[0098] As mentioned above, after the LR of the terminal device monitors the paging notification, it needs to send a second request information to the first network device to activate the first time interval. Therefore, the second time interval between the paging notification and its corresponding PO cannot be small, otherwise the paging message transmitted on the PO may be missed due to insufficient time to activate the first time interval.

[0099] To this end, an embodiment of the present application also provides a configuration scheme for a terminal device, which enables the terminal device to implement the above-mentioned working mode of "LR monitoring paging notification + MR receiving paging message" by configuring the identification information of the terminal device.

[0100] For example, Figure 6 As shown, before the aforementioned steps 210 to 240 , method 200 may further include steps 251 to 256 .

[0101] In step 251, the terminal device sends capability information of the terminal device to the second network device.

[0102] Correspondingly, the second network device receives the capability information of the terminal device sent by the terminal device.

[0103] In step 252, the second network device sends the capability information of the terminal device to the core network device.

[0104] Correspondingly, the core network device receives the capability information sent by the second network device.

[0105] Among them, the capability information of the terminal device is used by the core network device to configure identification information for the terminal device, and the identification information is used to determine the second time interval between the paging notification sent by the second network device and the PO indicated by it.

[0106] In the embodiment of the present application, the capability information of the terminal device is associated with the information of the receiver and SIM card supported by the terminal device. For example, the capability information of the terminal device includes one or more of the following: the terminal device supports MR and LR, and supports communication with different networks; the terminal device supports MR and LR, and supports MR and LR working with different networks at the same time, for example, when the MR works in another network while the LR monitors the paging notification of one network; the terminal device supports MR and LR, and the activation time information of the first time interval.

[0107] The activation time information of the first time interval of the terminal device may include, for example, one or more of the following: a threshold of the activation time of the first time interval; and a type of the terminal device.

[0108] The activation time threshold of the first time interval can be, for example, the lower limit of the activation time of the first time interval, that is, the minimum time required for the terminal device to activate the first time interval, such as 10ms. The type of terminal device is associated with the activation time of the first time interval. For example, for a certain type of terminal device, it must be prepared for a period of time in advance before it can get the first time interval to receive the paging message of the second network device. Therefore, the activation time of the first time interval also needs to consider the preparation time of this type of terminal device. At this time, the core network device can determine the corresponding activation time according to the type of the terminal device, so as to configure appropriate identification information for it.

[0109] The identification information of the terminal device should be configured so that the second time interval satisfies the condition for the first network device to configure the first time interval, for example, the second time interval is greater than or equal to the activation time of the first time interval. In this way, after the LR of the terminal device monitors the paging notification, it has enough time to activate the first time interval, and after the first time interval is activated, it promptly receives the paging message sent by the second network device through the MR.

[0110] The activation time of the first time interval may, for example, refer to the time from when the LR of the terminal device monitors the paging notification to when the first time interval is activated, i.e., it can be used by the MR to receive the paging message. For example, it may also be the time from when the terminal device sends the second request message to when the first time interval is activated.

[0111] In some implementations, the identification information of the terminal device includes a device identifier (UE ID) of the terminal device and a group identifier (UE group ID) of the terminal device. The device identifier of the terminal device is used to determine the PO, and the group identifier of the terminal device is used to determine the listening position of the paging notification.

[0112] The identification information of the terminal device is assigned by the core network device. For example, the PO is calculated based on the device identification of the terminal device assigned by the core network device. Another example is that the listening time of the paging notification is calculated based on the group identification of the terminal device assigned by the core network device. Usually, the network device can page multiple terminal devices on one PO, and the paging list of the paging message sent on the PO can carry the device identification of multiple terminal devices to be paged, where up to 32 terminal devices can be paged, for example. A group of terminal devices with the same group identification can listen to the paging notification and determine which terminal devices in the group will be paged in subsequent POs.

[0113] When the core network device allocates the device ID and group ID to the terminal device, it does not know the position of the listening time of the PO and paging notification calculated based on the device ID and group ID of the terminal device. Therefore, the second network device and / or the terminal device needs to calculate it.

[0114] For example, Figure 6 As shown, method 200 may further include steps 253 to 255 .

[0115] In step 253, the core network device sends the identification information configured for the terminal device.

[0116] In step 254, the second network device determines a second time interval.

[0117] The second network device receives the identification information of the terminal device sent by the core network, and calculates the second time interval based on the identification information, and executes step 255 when the second interval is greater than or equal to the activation time of the first time interval.

[0118] In step 255, the second network device sends confirmation information of the identification information to the core network device.

[0119] The confirmation information is used to indicate that the identification information configured for the terminal device can meet the activation time requirement of the first time interval. Otherwise, when the second time interval is less than the activation time of the first time interval, the second network device sends update information of the identification information to the core network device, and the update information is used to instruct the core network device to reconfigure the identification information of the terminal device so that the second time interval is greater than or equal to the activation time of the first time interval.

[0120] After the core network device receives the confirmation information sent by the second network device, it considers that the identification information configured for the terminal device meets the activation time requirement of the above-mentioned first time interval. After the core network device receives the update information sent by the second network device, it considers that the identification information configured for the terminal device cannot meet the activation time requirement of the above-mentioned first time interval, and it will re-allocate the device identification and / or group identification to the terminal device to increase the second time interval.

[0121] In addition, optionally, the core network device may also transparently transmit the identification information configured for the terminal device to the terminal device through a non-access stratum (NAS) message, etc. At this time, the terminal device executes step 256 .

[0122] In step 256, the terminal device calculates a second time interval.

[0123] Among them, if the terminal device calculates that the second interval is less than the activation time of the first time interval, it will not request the first network device to configure the first time interval, because the second time interval is not enough for the terminal device to activate the first time interval, and when the LR monitors the paging notification, it is too late to use the first time interval to receive the paging message on the corresponding PO; if the terminal device calculates that the second interval is greater than or equal to the activation time of the first time interval, indicating that it has the conditions for configuring the first time interval, it can execute the subsequent step 210 and request the first network device to configure the first time interval.

[0124] Of course, step 256 may not be performed, that is, the terminal device does not need to calculate the second time interval by itself, but instead notifies the terminal device through the second network device that the activation time requirement of the first time interval is not currently met. In this case, the terminal device will not apply for the first time interval from the first network device; otherwise, the terminal device may apply for a time interval from the first network device.

[0125] In other implementations, if the capability information of the terminal device does not include the activation time of the first time interval, then the capability information of the terminal device may be associated with the activation time of the first time interval. For example, if the capability information of the terminal device includes that the terminal device supports MR and LR and supports communication with multiple networks, then according to the capability of the terminal device, the activation time of the corresponding first time interval may be determined through the association relationship, thereby determining whether the second time interval meets the activation time requirement of the first time interval.
