The solutions proposed in the embodiments of this application are mainly applied to terminal devices configured with a discontinuous reception (DRX) mechanism or terminal devices configured with an extended discontinuous reception (eDRX) mechanism to monitor paging messages Scenes. In this scenario, the terminal device periodically enters the sleep mode (sleep mode) and does not monitor the paging message; and wakes up from the sleep state (wake up) in another period of the cycle to monitor the paging message through decoding The paging message is used to perform corresponding operations or update related parameters. Taking FIG. 1 as an example, the communication system includes an access network device 101, a terminal device 102, and a core network device 103.

Whether as a device or as a chip, the terminal device 102 can be manufactured, sold, or used as an independent product.

The user plane function (UPF) network element is not specifically limited here.

Based on the foregoing system architecture and application scenarios, the flow of the paging method will be introduced below, as shown in Figure 2, including the following steps:

201. The access network device configures the first parameter for the terminal device.

Specifically, the access network device may send the first parameter to the terminal device through dedicated signaling. For example, dedicated signaling such as a radio resource control release (RRC release) message; or, the access network device may broadcast the first parameter to the terminal device, which is not specifically limited here.

Among them, the terminal device is converted from the RRC connected state to the inactive state (inactive state) after the RRC release process. When the terminal device is in the inactive state, the access network device stores the context of the terminal device, and the context Refers to the link established between functional entities for information transmission. In addition, the access network device also stores connection information between the terminal device and the core network device. If the last access network device serving the terminal device receives downlink data from a UPF network element or downlink signaling from an AMF network element, the access network device is in the radio access network notification area (RAN). The aforementioned terminal equipment is paged in all cells in the notification area (RNA). Among them, the RNA area refers to the range where the access network device can page to the terminal device. Specifically, it can be understood that when the terminal device is located in the RNA area, the movement of the terminal device may not be reported to the core network. Only when the RNA timer of the terminal device expires or the terminal device moves out of the RNA range, the The terminal device only needs to initiate an RNAU (RAN-based notification area update) process to report to the core network device. In this embodiment, the RNA area may be one or more cells under the access network device, and the RNA area may also be composed of multiple cells under multiple access network devices, which is not specifically limited here. When the RNA area is composed of multiple cells under multiple access network devices, the access network device can send XnAP-RAN-Paging messages to other access network devices in the RNA area through the Xn port.

In addition, the first parameter is a parameter related to an eDRX period (eDRX period) or a paging time window (paging time window, PTW). Among them, the relationship between the eDRX cycle and PTW is shown in Figure 3. The terminal device configured with eDRX starts to monitor the paging occasion (paging occasion, PO) at the start position (PTW_start) of the PTW configured by the core network device for the terminal device. ) Until the end position (PTW_stop) of the PTW stops monitoring, or until a paging message containing the non-access stratum identification (NAS ID) of the terminal device is received during the PTW. It should be noted that the end of the monitoring paging time of the terminal device is the time corresponding to the end position (PTW_stop) of the aforementioned PTW and the time corresponding to the receipt of the aforementioned paging message containing the NAS ID, whichever is the earlier time. Prevail. The terminal device will try to receive a paging message (paging message) from the access network device at each PO in the PTW. It should be noted that what the terminal device monitors in each of the aforementioned POs is that the physical downlink control channel (PDCCH) is scrambled by the paging radio network temporary identity (P-RNTI). If the aforementioned paging downlink control information is monitored, it will further receive the paging message on the physical downlink shared channel (PDSCH). Therefore, the terminal device can control the flexibility of the terminal device to receive paging messages by adjusting the length of the PTW or the length of the eDRX cycle.

In this embodiment, the first parameter is used to adjust the ratio of the paging time window PTW to the eDRX cycle.

Optionally, the first parameter may be used to adjust the paging time window PTW parameter of the terminal device to obtain the target PTW. At this time, the first parameter may be a PTW scaling factor (PTW scaling factor), which is used to adjust the duration of the PTW of the terminal device to determine the duration of the target PTW; the first parameter may also be directly the target PTW In addition, the first parameter can also modify the duration of the PTW in other ways, for example, indicating a value in the predefined PTW length value list through a sequence number, which is not specifically limited here.

Optionally, the first parameter may also be used to adjust the eDRX cycle of the terminal device to obtain the target eDRX cycle. At this time, the first parameter may be an eDRX period scaling factor (eDRX period scaling factor), which is used to adjust the length of the eDRX period of the terminal device to determine the target eDRX period; the first parameter may also be directly It is the target eDRX cycle. In addition, the first parameter can also be used to modify the eDRX cycle in other ways. For example, a sequence number is used to indicate a value in a predefined eDRX cycle value list, which is not specifically limited here. .

In addition, it should also be understood that the access network device may configure the aforementioned first parameter for the terminal device when any of the following preset conditions are met:

In an optional preset condition, the preset condition for configuring the foregoing first parameter may be set according to the time synchronization between the access network devices in the RNA area. Optionally, when the time between each access network device in the RNA area is synchronized, PTW parameters can be configured to shorten the duration of the target PTW; when the time between each access network device in the RNA area is not During synchronization, PTW parameters can be configured to extend the duration of the target PTW. In addition, the time synchronization between the aforementioned two access network devices can be understood as that the time deviation between the two access network devices is within a certain threshold range; the time between the aforementioned two access network devices is not Synchronization can be understood as the time deviation between the two access network devices is greater than a certain threshold. For example, the terminal device is located in a cell under the candidate access network device in the RNA area, and the time between the access network device and the candidate access network device is synchronized. At this time, since the aforementioned access network device is the last connected access network device of the terminal device, the access network device retains the context of the terminal device. If the time of the access network equipment is synchronized with other access network equipment in the RNA area (ie, the aforementioned candidate access network equipment), the length of the PTW can be adjusted to control the terminal equipment to monitor the paging downlink control information and receive the paging The flexibility of the message. For example, shortening the duration of the aforementioned PTW can save the energy consumption of the terminal device; extending the aforementioned PTW can ensure that the terminal device will not easily miss the PO after moving or the terminal device after cell reselection. It is also possible to adjust the eDRX cycle to control the flexibility of the terminal equipment to monitor the paging downlink control information and receive the paging message. For example, extend the aforementioned eDRX cycle to save energy consumption of the terminal device; shorten the aforementioned eDRX cycle to speed up the time when the terminal device enters the next monitoring PO.

In another optional preset condition, the RNA area is a cell under the access network device. In other words, the terminal device only moves in a certain cell under the access network device. Since the terminal device does not miss the PO due to cell reselection, the access network device can shorten the PTW duration by configuring the first parameter to achieve the effect of energy saving.

In another optional preset condition, the terminal device is in a stationary state, or the moving track of the terminal device is relatively fixed and far from the edge of the cell. Wherein, whether the terminal device is far from the edge of the cell or close to the center of the cell can be measured by the signal quality of the terminal device. The signal quality of the terminal equipment can be determined by reference signal receiving power (RSRP), reference signal receiving quality (RSRQ), or signal to interference plus noise ratio (signal to interference plus noise ratio, SINR) At least one of them. For example, when the signal quality of the terminal device is greater than the second preset value, it can be considered that the terminal device is far away from the edge of the cell. Moreover, if the moving trajectory of the terminal device is relatively fixed, it can be understood that the terminal device will hardly perform cell reselection and will not miss the PO due to cell reselection. Therefore, the access network device can configure the first One parameter shortens the PTW to achieve the effect of energy saving.

It should be understood that the aforementioned first preset value and second preset value may be adjusted according to actual application scenarios, and this embodiment does not limit the specific data of the first preset value and second preset value.

202. The terminal device monitors the paging downlink control information from the access network device based on the first parameter.

In this embodiment, after the terminal device receives the first parameter from the access network device, the terminal device can listen to the access network device in a certain time window within the target eDRX cycle determined by the first parameter Paging the downlink control information and receive the paging message; or monitor the paging downlink control information from the access network device in the target PTW determined by the first parameter and receive the paging message; or, in the aforementioned target eDRX cycle The target PTW monitors the paging downlink control information from the access network device and receives the paging message. It can also be understood that the terminal device can listen to the paging downlink control information from the access network device and receive the paging message in several POs within the target eDRX cycle determined by the first parameter.

It should be understood that after the terminal device monitors the aforementioned paging downlink control information, it will also receive a paging message from the network device. Therefore, in some embodiments, it can also be interpreted as that the terminal device monitors the paging message from the access network device. In this embodiment and subsequent embodiments, the terminal device monitors the paging downlink control information and receives the paging message as an example for introduction.

203. The access network device sends the first parameter to the core network device.

In this embodiment, step 203 is an optional step. When the access network device executes step 203, there is no clear time sequence limitation for step 202 and step 203. That is to say, the step of the access network device sending the first parameter to the core network device is relatively independent of the step of the terminal device monitoring the paging downlink control information. It can be understood that the access network device may first send the first parameter to the core network device, and then the access network device sends a paging message to the terminal device based on the first parameter, so the terminal device may be based on the aforementioned The first parameter monitors the paging downlink control information from the access network device. It can also be understood that, while the access network device sends the aforementioned first parameter to the core network device, the access network device also sends a page to the terminal device based on the first parameter, and then the terminal device is based on the The first parameter monitors the paging downlink control information from the access network device, which is not specifically limited here.

After step 203 is performed, the core network device may obtain the first parameter, and determine the subsequent target PTW and/or target eDRX cycle according to the first parameter. In addition, when interacting with an access network device, the core network device can deliver the aforementioned target PTW and/or target eDRX cycle to the access network device through downlink data from UPF or downlink signaling from AMF.

In this embodiment, since the access network device can configure the first parameter for the terminal device, the first parameter can adjust the duration of the PTW or the length of the eDRX cycle, and further, can adjust the ratio of the duration of the PTW to the eDRX cycle. Therefore, the access network device can flexibly control the duration and timing of the paging process, that is, the flexibility of the paging process between the terminal device and the access network device is improved.

The following will further introduce the flow of the paging method, as shown in Figure 4, including the following steps:

401. The core network device configures a paging time window PTW for the terminal device.

In this embodiment, the core network device may send the length of the paging time window (PTW length) to the terminal device through signaling interaction with the terminal device. Optionally, when the core network device is an AMF network element, the core network device may configure PTW for the terminal device in the attach procedure. For example, the core network device carries the length of the paging time window in an attach accept message based on an attach request. Optionally, when the core network device is a UPF network element, the core network device may configure PTW for the terminal device in the terminal device tracking process. For example, the core network device carries the length of the paging time window in a tracking area update accept (tracking area update accept, TAU accept) message based on a tracking area update request (tracking area update request, TAU request). It should be understood that the foregoing only lists some common procedures that can be used to configure PTW for terminal devices, and other signaling procedures can also be reused in practical applications, which are not specifically limited here.

402. The core network device configures an inactive state conversion reporting mechanism for the terminal device for the access network device.

Among them, the reporting mechanism for the inactive state transition of the terminal device refers to that the access network device reports the inactive state transition situation of the terminal device to the core network device. The inactive state transition condition of the terminal device is used to indicate whether the terminal device has entered the inactive state. Optionally, the inactive state transition of the terminal device can be configured through the RRC Inactive Transition Report Request IE (RRC Inactive Transition Report Request IE). When the transition report is configured, the access network device will When the terminal device undergoes an inactive state transition, it notifies the core network through an RRC inactive transition report (RRC inactive transition report).

In this embodiment, the core network device may send the RRC Inactive Transition Report Request IE to the access network device through signaling interaction with the access network device. Optionally, the core network device may carry the RRC Inactive Transition Report Request IE in a context modification request (context modification request). At this time, the access network device may reply a context modification response (context modification response) message to the core network device to notify the core network device that the configuration is successful. Optionally, the core network device may carry the RRC Inactive Transition Report Request IE in an initial context setup request (initial context setup request). At this time, the access network device may reply an initial context setup response (initial context setup response) message to the core network device to notify the core network device that the configuration is successful.

In addition, in practical applications, the core network device may also configure the inactive state transition reporting mechanism for the terminal device for the access network device in other signaling, which is not specifically limited here. It should be understood that, after the core network device configures the access network device with the inactive state transition reporting mechanism for the terminal device, if the terminal device enters the inactive state, the access network device can report to the core The network device reports, that is, the access network device can send the inactive state transition status of the terminal device to the core network device

It should be understood that the access network device can report multiple times. For example, whenever the state of the terminal device changes from the idle state to the inactive state or from the connected state to the inactive state, the access network device can report the state of the terminal device to the core network device so that the The core network device can learn that the terminal device has entered an inactive state.

In this embodiment, when the first parameter in the foregoing embodiment corresponding to FIG. 2 is used to adjust the paging time window PTW configuration of the terminal device, the first parameter may be a PTW scale factor. At this time, the access network device will execute step 403a. When the first parameter in the embodiment corresponding to FIG. 2 is used to adjust the eDRX cycle of the terminal device, the first parameter may be an eDRX cycle scale factor. At this time, the access network device will execute step 403b.

403a. The access network device sends the PTW scale factor to the terminal device.

Wherein, the PTW scale factor is used to adjust the PTW duration of the terminal device. Optionally, the PTW scale factor is used to determine the target PTW, and the target PTW adopts the adjusted duration. Optionally, the product of the PTW scale factor and the duration of the initial PTW may determine the duration of the target PTW, that is, determine the target PTW. Therefore, the access network device can use the PTW scale factor to adjust the timing when the terminal device monitors the paging downlink control information and receives the paging message.

Optionally, the PTW scale factor is greater than 0 and less than 1. It can be understood that the access network device instructs the terminal device to shorten the duration of the PTW; it can also be understood that the access network device controls the terminal device to determine a shorter PTW as the target PTW. Since the terminal equipment monitors the paging downlink control information and receives the paging message requires power consumption, shortening the duration of the PTW shortens the time period for the terminal equipment to monitor the paging downlink control information in an eDRX cycle. Therefore, it is conducive to saving terminal equipment. It consumes energy and prolongs the standby time of the terminal equipment.

403b. The access network device sends the eDRX cycle scale factor to the terminal device.

Wherein, the eDRX cycle scale factor is used to adjust the eDRX cycle of the terminal device. Optionally, the eDRX cycle scale factor is used to determine the target eDRX cycle. Optionally, the product of the eDRX cycle scale factor and the initial eDRX cycle may determine the target eDRX cycle. Therefore, the access network device can use the eDRX cycle scale factor to adjust the frequency of sending access network paging messages (RAN-paging).

404a. The terminal device determines the target PTW based on the PTW scale factor, and monitors the paging downlink control information from the access network device in the target PTW.

In this embodiment, after the access network device performs step 403a, the terminal device will perform step 404a.

Specifically, please refer to the related introduction in step 403a, which will not be repeated here.

404b. The terminal device determines the target eDRX cycle based on the eDRX cycle scale factor, and monitors the paging downlink control information from the access network device in the PTW in the target eDRX cycle.

In this embodiment, after the access network device performs step 403b, the terminal device will perform step 404b.

Specifically, please refer to the related introduction in step 403b, which will not be repeated here.

405a. The access network device sends the PTW scale factor to the core network device.

Step 405a is an optional step. When the access network device executes step 405a, there is no clear time sequence limitation for step 405a and steps 403a to 404a. That is to say, the steps of the access network device sending the PTW scale factor to the core network device are independent of the steps of the terminal device determining the target PTW based on the PTW scale factor and monitoring the paging downlink control information from the access network device. It can be understood that the access network device may perform step 405a first, and then perform step 403a, and then the terminal device performs step 404a. It can also be understood that the access network device performs step 403a and step 405a at the same time, and then the terminal device performs step 404a.

After the access network device performs step 403a, the access network device may perform step 405a.

Optionally, the access network device may send the PTW scale factor to the core network device through an RRC inactive transition report (RRC inactive transition report). In addition, the access network device may also use other signaling with the core network device to transmit the PTW scale factor to the core network device, which is not specifically limited here.

In this embodiment, after the access network device sends the aforementioned PTW scale factor to the core network device, the core network device will also determine the target PTW based on the PTW scale factor, and submit paging to the access network device according to the target PTW information. Therefore, it is beneficial to ensure that the time range for the core network device to submit the paging message to the access network device is consistent with the time range for the terminal device to monitor the paging message from the access network device, and to ensure that the terminal device can be within the target PTW. The paging downlink control information from the access network device is monitored and the paging message is received.

405b. The access network device sends the eDRX cycle scale factor to the core network device.

Step 405b is an optional step. When the access network device executes step 405b, there is no clear time sequence limitation for step 405b and steps 403b to 404b. In other words, the step of the access network device sending the eDRX cycle scale factor to the core network device is mutually exclusive with the step of the terminal device determining the target eDRX cycle based on the eDRX cycle scale factor and monitoring the paging downlink control information from the access network device. independent. It can be understood that the access network device may perform step 405b first, and then perform step 403b, and then the terminal device performs step 404b. It can also be understood that the access network device performs step 403b and step 405b at the same time, and then the terminal device performs step 404b.

After the access network device performs step 403b, the access network device may perform step 405b.

Optionally, the access network device may send the eDRX cycle scale factor to the core network device through an RRC inactive transition report (RRC inactive transition report). In addition, the access network device may also use other signaling with the core network device to transmit the eDRX cycle scale factor to the core network device, which is not specifically limited here.

In this embodiment, after the access network device sends the aforementioned eDRX cycle scale factor to the core network device, the core network device will also determine the target eDRX cycle based on the eDRX cycle scale factor. At this time, the access network equipment and the core network equipment use the same cycle, which is conducive to data synchronization. If the target eDRX cycle is greater than the initial eDRX cycle, it is beneficial to save energy consumption of the terminal device and prolong the standby time of the terminal device.

Optionally, when the target eDRX cycle is any one of the optional eDRX cycle set, the access network device may not perform step 405b.

When executing 403b but not executing 405b, the core network still delivers downlink data from UPF network elements or downlink signaling from AMF network elements according to the original cycle, or sends core network paging (CN-paging) messages, but the access network The device can flexibly change the frequency of sending RAN-paging messages.

When 405b is executed, it can be understood that the access network device has modified the eDRX cycle parameters of the terminal device and the core network side at the same time. Optionally, the eDRX cycle scale factor is greater than 1. It can be understood that the access network device instructs the terminal device to extend the eDRX cycle; it can also be understood that the access network device reduces the number of times the terminal device monitors the paging downlink control information within a period of time; it can also be understood as access The network equipment controls the terminal equipment to determine a longer eDRX cycle as the target eDRX cycle. Since the terminal equipment monitors the paging downlink control information and receives the paging message requires power consumption, the longer eDRX cycle makes the terminal equipment prolong the time in the dormant state, and the ratio of the PTW duration of the terminal equipment to the eDRX cycle decreases, Compared with this, the time period that the terminal device needs to monitor the downlink control information of paging in the eDRX cycle is shortened. Therefore, it is beneficial to save the energy consumption of the terminal device and prolong the standby time of the terminal device.

It should be understood that the aforementioned steps 403a to 405a and steps 403b to 405b are independent of each other. That is to say, the PTW scale factor sent by the access network device to the terminal device does not affect the eDRX cycle scale factor sent by the access network device to the terminal device. The terminal device adjusts the duration of the PTW and/or the eDRX cycle based on the received first parameter. When the access network device only performs steps 403a and 403b, the terminal device will also perform steps 404a and 404b. At this time, the terminal device can determine the target PTW and the target eDRX cycle, that is, the terminal device will monitor the target PTW in the target eDRX cycle for the paging message from the access network device.

Optionally, when the first parameter is the duration of the target PTW, the PTW scale factor in the foregoing step 403a can be directly replaced with the duration of the target PTW. At this time, the terminal device in step 404a can directly use the target PTW without performing other calculations, that is, directly monitor the paging message from the access network device in the target PTW.

Optionally, when the first parameter is the target eDRX cycle, the eDRX cycle scale factor in the foregoing step 403b can be directly replaced with the duration of the target eDRX cycle. At this time, the terminal device in step 404b can directly use the target eDRX cycle without performing other calculations, that is, directly monitor the information from the access network device in the time window (for example, the paging time window) in the target eDRX cycle. Paging message.

Based on the foregoing system architecture and application scenarios, an embodiment of the present application also proposes a system information update method. The following will introduce the process of the system information update method, as shown in Figure 5, including the following steps:

501. A terminal device receives a first message from an access network device.

In this embodiment, when the system information in the access network device changes, the access network device may send the first message to the terminal device. Then, the terminal device can receive the first message from the access network device. The first message includes at least first indication information, and the first indication information is used to instruct the terminal device to obtain updated system information (that is, new system information) at a certain time after receiving the first message. Specifically, the first indication information is used to instruct the terminal device to obtain updated system information immediately, or to instruct the terminal device to obtain updated system information after a first offset time (offset time), or to indicate that the terminal device is broadcasting The control channel (broadcast control channel, BCCH) modifies the cycle boundary to obtain updated system information.

Optionally, the first indication information may be located in the paging downlink control information (paging downlink control information, paging DCI) scrambled by the paging radio network temporary identity (P-RNTI), at this time , The first message may be paging downlink control information. Alternatively, the first indication information may also be carried in a short message (short message) in the paging downlink control information. In this case, the first message may be the aforementioned short message. Alternatively, the first indication information may be located in a paging message (paging message) carried on a physical downlink shared channel (PDSCH). At this time, the first message may be the aforementioned paging message. In addition, in 5G NR or subsequent evolution standards, the first indication information may also be carried in other messages or signaling. Specifically, the embodiment of the present application does not limit the message that carries the first indication information.

502. The terminal device obtains updated system information according to the first message.

In this embodiment, the terminal device will obtain updated system information based on the content indicated by the foregoing first indication information. In other words, the terminal device can obtain updated system information immediately, or after the first offset duration, or obtain updated system information on the BCCH modification period boundary of the broadcast control channel.

Specifically, refer to the foregoing step 501, which will not be repeated here.

In this embodiment, since the terminal device can immediately obtain updated system information based on the first indication information or obtain updated system information after the first offset duration, compared to the prior art, it must be after the eDRX system message obtains the boundary. In the solution for obtaining updated system information, this embodiment advances the range in which the terminal device can obtain updated system information, which is beneficial to improve the flexibility of the terminal device to obtain updated system information, and is beneficial to shorten the time required for the terminal device to obtain updated system information. Time delay.

Based on the foregoing embodiment, the system information update method will be further introduced below. Specifically, as shown in Figure 6, the system information update method includes the following steps:

601. A terminal device receives a first message from an access network device.

Wherein, the first message includes at least first indication information, and the first indication information is used to indicate that the system information in the access network device is about to change, so that the terminal device can obtain the information at a certain time after receiving the first message. Updated system information. Specifically, reference may be made to the relevant introduction in the foregoing step 501, which will not be repeated here.

In this embodiment, the first message may further include other indication information in different scenarios, so that the terminal device obtains updated system information at different times based on the aforementioned different indication information. The following are introduced separately:

In an optional implementation manner, the first message includes first indication information and second indication information. Wherein, the first indication information is used to indicate to the first terminal device the modification of the broadcast control channel BCCH, and the second indication information is used to indicate to the second terminal device the modification of the BCCH. That is to say, the aforementioned first indication information and second indication information are for indicating different terminal devices, and the content of the indication is that the BCCH of the access network device is modified, so that the aforementioned different terminal devices will be at a later time. Get updated system information. Wherein, the eDRX cycle of the first terminal device is longer than the BCCH modification cycle. That is, the first terminal device is a terminal device configured with an eDRX mechanism, and the eDRX cycle is longer than the BCCH modification cycle, that is, the eDRX cycle is longer than the system information modification cycle. In addition, the second terminal device is a terminal device that is not configured with an eDRX cycle. For example, the second terminal device is a terminal device other than the first terminal device, or a terminal device configured with only a DRX mechanism.

In addition, it can also be understood that the first indication information is used to indicate that the system information of the terminal device configured with the eDRX mechanism is changed, and the second indication information is used to indicate that the system information of the terminal device configured with the DRX mechanism is changed.

In addition, similar to the foregoing first indication information, the second indication information may be located in the paging DCI scrambled by the P-RNTI. In this case, the first message may be paging downlink control information. Alternatively, the first indication information may also be carried in a short message (short message) in the paging downlink control information. In this case, the first message may be the aforementioned short message. Alternatively, the second indication information may be located in a paging message (paging message) carried on the PDSCH. In addition, in 5G NR or subsequent evolution standards, the second indication information may also be carried in other messages or signaling. In addition, in 5G NR or subsequent evolution standards, the second indication information may also be carried in other messages or signaling. Specifically, the embodiment of the present application does not limit the message that carries the second indication information.

Optionally, the first indication information is systemInfoModification-eDRX; the second indication information is systemInfoModification. It should be understood that, in actual applications, other characters or fields may also be used to represent the foregoing first indication information and second indication information, which is not specifically limited here.

In this embodiment, when the terminal device determines that the first message includes the foregoing first indication information and second indication information, the terminal device will execute step 602a.

In another optional implementation manner, the first message includes only the first indication information and does not include the second indication information. The first indication information is used to indicate to the first terminal device the modification of the broadcast control channel BCCH. The eDRX cycle of the first terminal device is longer than the BCCH modification cycle. It can also be understood that the first indication information is used to notify the eDRX-configured terminal device that the system information of the terminal device has changed. Optionally, the first indication information is systemInfoModification-eDRX. Specifically, reference may be made to the introduction of the first indication information in the foregoing embodiment, and details are not described herein again.

In this embodiment, when the terminal device determines that the first message only includes the aforementioned first indication information and does not include the second indication information, the terminal device will perform step 602b.

In another optional implementation manner, the first message includes the first offset duration. Optionally, the first indication information is the first offset duration; or, the first message includes the first indication information and the first offset duration.

Wherein, when the first indication information is the first offset duration, the position carried by the first offset duration may refer to the related description of the position carried by the first indication information, which will not be repeated here.

When the first message includes the first indication information and the first offset duration, the first offset duration may be carried in the same message as the first indication information, or may be carried in a different message from the first indication information. In the message, there is no specific limitation here. For example, the first indication information is carried in a short message in the paging downlink control information, and the first offset duration is carried in the paging downlink control information, but is not in the short message. In practical applications, there may also be other bearing forms, and the details are not listed here.

In this embodiment, when the terminal device determines that the first message includes the first offset duration, the terminal device will perform step 602c.

602a. The terminal device obtains updated system information at the boundary of the BCCH modification period.

In this embodiment, when the first message includes the first indication information and the second indication information, the terminal device will obtain the updated system information at the boundary of the BCCH modification period. Or, it can also be understood that the terminal device can obtain the updated system information at the boundary of the BCCH modification period at the earliest. Since the length of the eDRX system message acquisition period is multiple times the length of the BCCH modification period, there may be multiple BCCH modification period boundaries before the eDRX system message acquisition period boundary. Therefore, it should also be understood that the aforementioned BCCH modification period boundary refers to the next BCCH modification period boundary after the terminal device receives the first message. It can also be understood as the most recent BCCH modification period boundary after the terminal device receives the first message. The BCCH modifies the cycle boundary. For ease of understanding, take FIG. 7A as an example for introduction. If the terminal device receives the aforementioned first message at time T4, and the aforementioned first message includes the first indication information and the second indication information, the terminal equipment is the earliest at time T2. Then you can get updated system information.

Therefore, the time at which the aforementioned terminal device obtains the updated system information is no earlier than the BCCH modification period boundary, and no later than the aforementioned eDRX system message acquisition boundary. In other words, the terminal device will obtain updated system information at the BCCH modification period boundary or after the BCCH modification period boundary. For ease of understanding, Figure 7A is still used as an example for introduction. If the first message received by the terminal device includes the foregoing first indication information and the second indication information, the terminal device can determine that the time when the first message is received is within the nth BCCH modification period (that is, time T1 to time T2) Scope), and the access network device will send updated system information to the terminal device at the beginning of the n+1th BCCH modification period (that is, after time T2). At this time, the terminal device can determine that the updated system information can be obtained at time T2. However, the terminal device has not yet determined the time interval between the current time and the T2 time. Therefore, the terminal device needs to calculate the exact position of the T2 time, which can also be understood as calculating the time difference between the time when the terminal device receives the first message and the time T2, that is, the time difference between the time T4 and the time T2 . When the terminal device determines the exact location at time T2, the terminal device can obtain updated system information from time T2 to time T3. Therefore, the range of system information that can be updated is [T2, T3].

In this embodiment, since the terminal device can obtain updated system information at the BCCH modification period boundary, the BCCH modification period boundary is generally earlier than the eDRX system message acquisition boundary. Compared with the prior art solution in which the updated system information must be obtained after the eDRX system message acquisition boundary, this embodiment advances the range in which the terminal device can obtain the updated system information, which is beneficial to improve the terminal device's ability to obtain the updated system information. flexibility. In addition, compared with the prior art, which must check the validity of system information before access and obtain updated system information when the system information becomes invalid, it is beneficial to shorten the time delay introduced by the terminal device in obtaining updated system information before access.

602b. The terminal device immediately obtains updated system information.

In this embodiment, when the first message includes the first indication information but does not include the second indication information, the terminal device immediately obtains the updated system information.

For ease of understanding, take Fig. 7B as an example for introduction. If the first message received by the terminal device only includes the aforementioned first indication information but not the second indication information, the terminal device can determine that the time of receiving the first message is later than the beginning of the n+1th BCCH modification period. Start position (that is, after time T2). For example, the terminal device receives the first message at time T5. At this time, the terminal device can immediately obtain updated system information. Optionally, the terminal device can obtain updated system information between time T5 and time T3. Therefore, the range in which the terminal device may obtain updated system information is [T5, T3].

In this embodiment, since the terminal device can obtain updated system information as soon as possible based on the aforementioned first message, in addition to improving the flexibility of the terminal device to obtain updated system information, it can further shorten the time required for the terminal device to obtain updated system information before accessing. Time delay caused by system messages.

602c. The terminal device obtains updated system information after receiving the first offset duration of the first message.

Wherein, the first indication information is the first offset duration; or, in addition to the aforementioned first indication information or the second indication information, the first message also includes the first offset duration.

When the first indication information is the first offset duration, the terminal device obtains the updated system information after receiving the first offset duration in the first message. Taking Figure 7C as an example, if the terminal device receives the first message at the time T6 and indicates the first offset duration, the terminal device can be at the first offset duration after the T6 time (that is, the T7 time ) Get updated system information. It can also be understood that the terminal device can acquire the updated system information at the first offset duration of the aforementioned first message (that is, time T7) at the earliest.

In addition, in addition to the first offset duration, the first message may also include the aforementioned at least one kind of indication information.

Optionally, the first message includes first indication information, second indication information, and first offset duration. Because when the first message includes the foregoing first indication information and the second indication information, the terminal device obtains updated system information at the boundary of the BCCH modification period. (For details, please refer to the foregoing step 602a) Therefore, the first offset duration is the duration between the moment when the terminal device receives the first message and the BCCH modification period boundary. Taking FIG. 7C as an example, the first offset duration is the duration between time T4 and time T2. In this implementation manner, the terminal device can directly determine the earliest time when the updated system information can be obtained according to the first offset time, without calculation, which is beneficial to reduce the calculation amount of the terminal device and save the energy consumption of the terminal device. .

Optionally, the first message includes the first indication information and the first offset duration, and does not include the second indication information. At this time, the terminal device obtains the updated system information at a time corresponding to the first offset duration after receiving the first message. In particular, the first offset duration may be 0. In this case, the terminal device can immediately obtain the updated system information. In this implementation manner, it is possible to flexibly control the time when the terminal device obtains updated system information by adjusting the first offset duration, which is beneficial to improve the flexibility of the terminal device to obtain updated system information, and is beneficial to reduce the time for the terminal device to access the cell. Extension.

It should be understood that the terminal device can perform any one of the foregoing step 602a, step 602b, and step 602c. The terminal device may also execute the foregoing step 602a and step 602c at the same time; or, the terminal device may execute the foregoing step 602b and step 602c at the same time, which is not specifically limited here.

Based on the foregoing embodiment, for a system information change, the access network device may send the foregoing first message multiple times in succession. Therefore, the terminal device may receive the first message multiple times, and the terminal device may mistakenly believe that the system information has occurred. Multiple changes and repeated acquisition of updated system information cause unnecessary power consumption. In this regard, in some optional implementation manners, the aforementioned first message may further include third indication information, and the third indication information is used to indicate whether the updated system information has been changed. Optionally, the third indication information may be carried in a short message. For example, if 1 bit is set in the short message, if the bit in the third indication message currently received by the terminal device is not overturned compared to the bit in the third indication message received by the terminal device last time, the terminal device It may be determined that the third indication information indicates the last system information modification, or the terminal device determines that the repeated first message has been received. If the bits in the third indication information currently received by the terminal device are flipped compared to the bits in the third indication information received by the terminal device last time, the terminal device will obtain the updated information according to the aforementioned first message. system message. In such an embodiment, it is beneficial to prevent the terminal device from repeatedly acquiring the same system information and causing power consumption.
