Description

Information interception method, communication device and storage medium

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on March 1, 2024, with application number 202410240018.2 and application name “Information Interception Method, Communication Device and Storage Medium”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to an information interception method, a communication device, and a storage medium. Background Art

[0003] In a communication network, network equipment can send an alert to a terminal, indicating a paging failure. Upon receiving the alert, the terminal can remind the user to relocate the terminal to an area where the antenna is not significantly obstructed, allowing the terminal to receive the paging message from the network equipment and proceed normally. However, currently, terminals must continuously listen for alerts to receive these messages, which significantly consumes the terminal's battery. Summary of the Invention

[0004] In order to solve the above technical problems, the embodiments of the present application provide an information monitoring method, a communication device and a storage medium to prevent the terminal from continuously monitoring the alarm information, thereby reducing the power consumption of the terminal.

[0005] In a first aspect, a method for monitoring information is provided. The method can be executed by a first terminal, or by a component of the first terminal, such as a processor, chip, or chip system of the first terminal, or by a logic module or software that can implement all or part of the first terminal. The following description uses the method performed by the first terminal as an example. The method for monitoring information includes: obtaining a first time domain resource and monitoring first indication information on the first time domain resource, wherein the first time domain resource is a time domain resource for the first terminal to monitor the first indication information, and the first indication information is used to indicate a paging failure.

[0006] In an embodiment of the present application, the first terminal can obtain a first time domain resource for listening to the first indication information, and listen to the first indication information on the first time domain resource. In this way, the first terminal only needs to listen to the first indication information on the first time domain resource, and does not need to continuously listen to the first indication information, thereby avoiding a large amount of power consumption of the terminal.

[0007] In combination with the above-mentioned first aspect, in a possible implementation method, the first time domain resource includes at least one time domain resource in a first time domain resource set, and the first time domain resource set includes time domain resources shared by multiple terminals for listening to the first indication information. The multiple terminals include the first terminal, that is, the first terminal can share the time domain resources for listening to the first indication information with other terminals, so that resource utilization can be improved as much as possible.

[0008] Alternatively, the first time domain resource includes at least one time domain resource in the second time domain resource set, and the second time domain resource set includes the time domain resource allocated to the first terminal for listening to the first indication information. That is to say, different terminals have their own corresponding time domain resources for listening to the first indication information. This can avoid conflicts in the process of each terminal listening to the first indication information as much as possible, and thus ensure that each terminal can listen to the first indication information normally as much as possible.

[0009] Alternatively, the first time domain resource includes at least one time domain resource in a third time domain resource set, and the third time domain resource set includes time domain resources allocated to the first terminal for listening to paging information. That is to say, the first terminal can reuse the time domain resources corresponding to the first terminal for listening to paging information to listen to the first indication information. In this way, there is no need to separately configure time domain resources for the first indication information, and conflicts in the process of each terminal listening to the first indication information are avoided as much as possible. Therefore, while saving time domain resources, it is also guaranteed as much as possible that each terminal can listen to the first indication information normally.

[0010] In combination with the above-mentioned first aspect, in a possible implementation method, obtaining the first time domain resource includes: receiving second indication information from a network device, the second indication information is used to indicate the first time domain resource, so that the first terminal can directly obtain the first time domain resource through the second indication information, thereby saving the computational burden of the first terminal in determining the first time domain resource.

[0011] In combination with the foregoing first aspect, in a possible implementation manner, obtaining the first time domain resource includes: determining the first time domain resource according to preconfigured time domain resource allocation information.

[0012] That is to say, in addition to directly obtaining the first time domain resource, the first terminal can also determine the first time domain resource based on the pre-configured time domain resource allocation information. In this way, when the network device is unable to provide the first time domain resource for the first terminal, the first terminal can also determine the first time domain resource by itself based on the pre-configured time domain resource allocation information. In other words, another implementation method for obtaining the first time domain resource is provided, thereby improving the reliability of the first terminal in determining the first time domain resource.

[0013] In combination with the above-mentioned first aspect, in a possible implementation manner, the method provided in an embodiment of the present application also includes: obtaining a second time domain resource, the second time domain resource including a time domain resource after the first time domain resource, in which the first terminal listens to paging information; and listening to paging information on the second time domain resource.

[0014] That is to say, after the first time domain resource, the first terminal can be informed of the paging failure through the first indication information heard, and then the first terminal can remind the user to place the first terminal in an area where the antenna is not severely blocked, that is, in the subsequent process, the first terminal can receive the paging information normally. In view of this, the first terminal can obtain the second time domain resource for listening to the paging information, and listen to the paging information on the second time domain resource, so that the first terminal only needs to listen to the paging information on the second time domain resource to normally obtain the paging information, without the need to continuously listen to the paging information, thereby saving the power of the first terminal while enabling the state of the first terminal to be switched from the idle state to the connected state.

[0015] In combination with the above-mentioned first aspect, in a possible implementation method, obtaining the second time domain resource includes: receiving third indication information from the network device, the third indication information is used to indicate the second time domain resource, so that the first terminal can directly obtain the second time domain resource through the third indication information, thereby saving the computational burden of the first terminal in determining the second time domain resource.

[0016] In combination with the above first aspect, in a possible implementation manner, obtaining the second time domain resource includes: determining the second time domain resource according to the first time domain resource and / or the preset time domain resource.

[0017] That is to say, in addition to directly obtaining the second time domain resources, the first terminal can also determine the second time domain resources based on the first time domain resources and / or the preset time domain resources. In this way, when the network device is unable to provide the second time domain resources for the first terminal, the first terminal can also determine the second time domain resources based on the first time domain resources and / or the preset time domain resources. In other words, another implementation method for obtaining the second time domain resources is provided, thereby improving the reliability of the first terminal in determining the second time domain resources.

[0018] In combination with the above-mentioned first aspect, in a possible implementation method, the preset time domain resources are determined based on the third time domain resources and / or the fourth time domain resources, the third time domain resources include the time domain resources for the network device to send the paging information of the first terminal, and the fourth time domain resources include the time domain resources separated between the first time domain resources and the time domain resources for the network device to send the paging information of the first terminal.

[0019] That is to say, the third time domain resource and the fourth time domain resource are both time domain resources related to the time domain resources of the network device sending the paging information of the first terminal. The first terminal determines the preset time domain resource based on the third time domain resource and / or the fourth time domain resource, so that the preset time domain resource is also related to the time domain resource of the network device sending the paging information of the first terminal. In this way, the second time domain resource determined based on the preset time domain resource can be closer to the time domain resource of the network device sending the paging information of the first terminal. That is to say, the overlap between the above-mentioned second time domain resource and the time domain resource of the network device sending the paging information of the first terminal can be increased as much as possible, thereby ensuring that the first terminal can hear the paging information on the second time domain resource as much as possible.

[0020] In combination with the above-mentioned first aspect, in a possible implementation method, the method provided in an embodiment of the present application also includes: receiving fourth indication information from a network device, the fourth indication information being used to indicate a third time domain resource, so that the first terminal can directly obtain the third time domain resource through the fourth indication information, so that the first terminal can subsequently determine the preset time domain resource based on the third time domain resource, thereby providing effective data preparation.

[0021] In combination with the above-mentioned first aspect, in a possible implementation method, the method provided by the embodiment of the present application also includes: when the signal quality of the first terminal is greater than the first threshold, determining that it is necessary to listen to the paging information on the second time domain resources, that is, when the signal quality of the first terminal is good, the first terminal has the ability to normally receive the paging information, so that it is determined that it is necessary to listen to the paging information on the second time domain resources, thereby avoiding the situation where the first terminal does not have the ability to normally receive the paging information, and still causes the first terminal to listen to the paging information, thereby avoiding the first terminal's power being consumed by redundant operations.

[0022] In combination with the above-mentioned first aspect, in a possible implementation method, the method provided by the embodiment of the present application also includes: the access layer AS of the first terminal receives fifth indication information from the upper layer of the AS of the first terminal, and the fifth indication information is used to instruct the first terminal to listen to paging information; the AS of the first terminal determines, based on the fifth indication information, that it is necessary to listen to paging information on the second time domain resources.

[0023] That is to say, if the AS of the first terminal receives the fifth indication information for instructing to listen to the paging information, the first terminal will determine that it needs to listen to the paging information on the second time domain resources, thereby avoiding the first terminal listening to the paging information when the first terminal does not have the ability to receive the paging information normally, thereby avoiding the first terminal's power being consumed by redundant operations.

[0024] In combination with the above-mentioned first aspect, in a possible implementation method, the first indication information is also used to indicate paging reason information, and the paging reason information is used to indicate that the paging information of the first terminal is triggered by a voice service; the method provided in the embodiment of the present application also includes: initiating a random access process to the network device.

[0025] That is to say, if the first indication information is also used to indicate the paging reason information, it means that the network device will not send the paging information again, so that the first terminal can directly initiate the random access process, so that when the network device no longer resends the paging, the first terminal can still change the state of the first terminal from the idle state back to the connected state.

[0026] In combination with the above-mentioned first aspect, in a possible implementation method, the method provided in the embodiment of the present application also includes: when the first terminal receives a short message but the first terminal cannot receive system information, the AS of the first terminal sends a sixth indication message to the upper layer of the AS of the first terminal, and the sixth indication information is used for the failure to receive the system information, wherein the short message is used to indicate that the system information has changed.

[0027] That is to say, after the first terminal receives the short message, if the antenna of the first terminal is severely blocked, it is very likely that the first terminal will not be able to receive the system information, and thus the system information of the first terminal needs to be updated but cannot be updated normally. In this case, the AS of the first terminal can send sixth indication information to the upper layer of the AS of the first terminal. The sixth indication information is used for the failure to receive the system information. In this way, the upper layer of the AS of the first terminal can be informed of the failure to receive the system information, so that the upper layer of the AS of the first terminal can remind the user to move the first terminal to an area where the antenna is not severely blocked, so that the first terminal can receive the system information normally, and thus the system information update process can proceed normally.

[0028] In a second aspect, an information interception method is provided. The method can be executed by a network device, or by a component of the network device, such as a processor, chip, or chip system of the network device, or can be implemented by a logic module or software that can implement all or part of the network device. The following description takes the method executed by the network device as an example. The information interception method includes: determining a first time domain resource, and sending first indication information to a first terminal on the first time domain resource, wherein the first time domain resource is a time domain resource for the first terminal to intercept the first indication information, and the first indication information is used to indicate a paging failure.

[0029] In combination with the above-mentioned second aspect, in a possible implementation method, the first time domain resource includes at least one time domain resource in a first time domain resource set, the first time domain resource set includes time domain resources shared by multiple terminals for listening to first indication information, and the multiple terminals include the first terminal; or, the first time domain resource includes at least one time domain resource in a second time domain resource set, the second time domain resource set includes time domain resources allocated to the first terminal for listening to the first indication information; or, the first time domain resource includes at least one time domain resource in a third time domain resource set, and the third time domain resource set includes time domain resources allocated to the first terminal for listening to paging information.

[0030] In combination with the above-mentioned second aspect, in a possible implementation manner, the method provided in an embodiment of the present application further includes: sending second indication information to the first terminal, where the second indication information is used to indicate the first time domain resource.

[0031] In combination with the above-mentioned second aspect, in a possible implementation method, the method provided in an embodiment of the present application also includes: determining a third time domain resource, and sending paging information of the first terminal on the third time domain resource, wherein the third time domain resource includes the time domain resource to which the network device sends the paging information of the first terminal after the first time domain resource.

[0032] In combination with the above-mentioned second aspect, in a possible implementation method, the method provided in an embodiment of the present application also includes: sending third indication information to the first terminal, the third indication information is used to indicate a second time domain resource, and the second time domain resource includes a time domain resource after the first time domain resource, and the first terminal listens to the paging information.

[0033] In combination with the above-mentioned second aspect, in a possible implementation method, the method provided in an embodiment of the present application also includes: sending fourth indication information to the first terminal, the fourth indication information is used to indicate the third time domain resources and / or the fourth time domain resources, and the fourth time domain resources include the time domain resources separated by the first time domain resources and the time domain resources for the network device to send the paging information of the first terminal.

[0034] In combination with the above-mentioned second aspect, in a possible implementation method, the first indication information is also used to indicate paging reason information, and the paging reason information is used to indicate that the paging information of the first terminal is triggered by a voice service; the method provided in the embodiment of the present application also includes: responding to the random access process initiated by the first terminal.

[0067] To facilitate understanding of the technical solutions provided by the embodiments of this application, a brief introduction to the relevant technologies of this application is first given. The brief introduction is as follows:

[0068] 1. Non-terrestrial network (NTN)

[0069] NTN has the advantages of wide coverage, long communication distance, high reliability, great flexibility, and high throughput. It is also unaffected by geographical environment, climatic conditions, and natural disasters. Therefore, NTN has been widely used in aviation communications, maritime communications, and other fields.

[0070] With the widespread use of NTN, terminals can combine NTN with the fifth generation mobile communication technology (5G) to obtain a new type of communication network (which can be recorded as an NTN-based 5G network). The above-mentioned NTN-based 5G network can provide communication services for terminals in areas that are difficult to cover by terrestrial networks (for example, oceans, forests, etc.), allowing terminals located on transportation vehicles such as trains and airplanes to use more stable and higher-quality communication services. In addition, the above-mentioned NTN-based 5G network can also provide more data transmission resources and support a larger number of communication connections, thereby enhancing the reliability of 5G communications.

[0071] Furthermore, generally, a 5G network based on NTN may include a radio access network (RAN), a 5G core network (CN), and a data network (DN).

[0072] The following uses satellite communications as an example to illustrate the functions provided by satellites in the RAN. Optionally, the functions provided by satellites in the RAN can be categorized into the following four scenarios: Scenario 1: The satellite acts as a transparent forwarding unit, providing terminals with services such as radio frequency filtering, frequency conversion, and amplification; Scenario 2: The satellite acts as an access network device, providing terminals with all services supported by the access network device; Scenario 3: The satellite acts as a device with only next-generation NodeB (gNB)-distributed unit (DU) functionality, providing terminals with a subset of services supported by the access network device, such as physical layer message processing; and Scenario 4: The satellite acts as a device integrating gNB-DU functionality and integrated access and backhaul (IAB) functionality, providing terminals with a subset of services supported by the access network device, as well as services that enable direct communication with terrestrial core network elements. The different functions provided by satellites in the RAN will lead to different RAN network architectures, and consequently, different network architectures for 5G networks based on NTNs. Therefore, the following describes the network architectures for 5G networks based on NTNs in each of the four scenarios described above.

[0073] Case 1: The satellite acts as a transparent forwarding unit, providing wireless frequency filtering, frequency conversion, and amplification services to the terminal.

[0074] In scenario 1, as shown in Figure 1, a schematic diagram of the structure of a 5G network based on NTN is provided in an embodiment of the present application. Figure 1 illustrates an example of a 5G network based on NTN 100 including a terminal 101, a RAN 102, a core network 103, and a data network 104. RAN 102 includes a satellite 1021, a gateway 1022, and terrestrial access network equipment 1023.

[0075] In an NTN-based 5G network 100, terminal 101 can communicate with satellite 1021 via a Uu interface. Satellite 1021 can communicate with gateway 1022 via a microwave link between the satellite and the gateway. Gateway 1022 can communicate with terrestrial access network equipment 1023 via a wired link. Terrestrial access network equipment 1023 can communicate with core network 103 via an NG interface. Core network 103 can communicate with DN 104 via an NG interface.

[0076] It's understandable that in scenario 1, the satellite can be understood as the remote radio unit (RRU) in the terrestrial access network equipment, providing only simple physical signal coverage. The satellite needs to communicate with the terrestrial access network equipment through a gateway and a microwave link between the satellite and the gateway. Furthermore, during signal transmission from the terminal to the terrestrial access network equipment, the transmitted signal does not require any protocol layer processing, nor does it require the establishment of any new logical interfaces.

[0077] Case 2: Satellites serve as non-terrestrial access network devices, providing terminals with all services supported by access network devices.

[0078] In scenario 2, as shown in Figure 2, another schematic diagram of the structure of an NTN-based 5G network provided in an embodiment of the present application is provided. Figure 2 illustrates an example of an NTN-based 5G network 200 including a terminal 201, a RAN 202, a core network 203, and a data network 204. RAN 102 includes a satellite 2021 and a gateway 2022.

[0079] Compared to the NTN-based 5G network shown in Figure 1, in the NTN-based 5G network shown in Figure 2, since satellite 2021 has all the functions supported by access network equipment, that is, satellite 2021 can directly provide all services supported by access network equipment to terminals, RAN 102 does not need to include terrestrial access network equipment. In this case, the microwave link between the satellite and the gateway can be called the link corresponding to the satellite radio interface (SRI).

[0080] It is understandable that other descriptions about the NTN-based 5G network shown in Figure 2 can be understood by referring to the description of the NTN-based 5G network shown in Figure 1, and will not be explained here.

[0081] It should be noted that in the NTN-based 5G network shown in Figure 2, satellites cannot communicate with each other. In view of this, Figure 3 shows a schematic diagram of the structure of another NTN-based 5G network provided in an embodiment of the present application. In the NTN-based 5G network shown in Figure 3, satellites can communicate with each other. Specifically, Figure 3 uses the NTN-based 5G network 300 as an example, including two terminals 301, two RANs 302, two core networks 303, and two data networks 304. In addition, Figure 3 uses one RAN 302 including one satellite 3021 and one gateway 3022 as an example.

[0082] Compared to the NTN-based 5G network shown in FIG2 , in the NTN-based 5G network shown in FIG3 , satellites 3021 can communicate with each other via inter-satellite wireless links. In this case, the inter-satellite wireless links for communication are referred to as inter-satellite links (ISLs).

[0083] It can be understood that other descriptions about the NTN-based 5G network shown in Figure 3 can be understood by referring to the description about the NTN-based 5G network shown in Figure 1 and the description about the NTN-based 5G network shown in Figure 2, and will not be explained here.

[0084] Case 3: The satellite, as a device with only gNB-DU functionality, provides the terminal with some services supported by the access network equipment, such as services for processing physical layer messages.

[0085] In scenario 3, as shown in Figure 4, a schematic diagram of the structure of another NTN-based 5G network provided in an embodiment of the present application is provided. In Figure 4, the NTN-based 5G network 400 includes a terminal 401, a RAN 402, a core network 403, and a data network 404. The RAN 402 includes a satellite 4021, a gateway 4022, and a ground-based centralized unit (CU) 4023.

[0086] Compared to the NTN-based 5G network shown in Figure 1 , in the NTN-based 5G network shown in Figure 4 , since satellite 4021 only has gNB-DU functionality, RAN 402 also needs to include a ground-based CU 4023 . Gateway 4022 can communicate with ground-based CU 4023 .

[0087] It can be understood that other descriptions about the NTN-based 5G network shown in Figure 4 can be understood by referring to the description of the NTN-based 5G network shown in Figure 1, and will not be explained here.

[0088] Case 4: Satellites, as devices integrating gNB-DU and IAB functions, provide terminals with some services supported by access network devices, as well as services that can directly communicate with terrestrial core network elements.

[0089] In scenario 4, as shown in Figure 5, a schematic diagram of the structure of another NTN-based 5G network provided in an embodiment of the present application is provided. In Figure 5, the NTN-based 5G network 500 includes a terminal 501, a RAN 502, a core network 503, and a DN 504. The RAN 502 includes a satellite 5021 and a terrestrial access network device 5022.

[0090] Compared with the NTN-based 5G network shown in Figure 4, in the NTN-based 5G network shown in Figure 5, since the satellite 5021 is not only deployed with a module with gNB-DU function, but also deployed with a mobile terminal (mobile termination, MT) module for performing IAB function, the satellite 5021 can directly connect to the ground access network device 5022 without the need for transit through the signal gateway station.

[0091] It can be understood that other descriptions about the NTN-based 5G network shown in Figure 5 can be understood by referring to the description about the NTN-based 5G network shown in Figure 1 and the description about the NTN-based 5G network shown in Figure 4, and will not be explained here.

[0092] It should be noted that the higher the orbital altitude of non-terrestrial communication equipment (e.g., satellites, drones, etc.) in the NTN, that is, the higher the altitude of the location point in the orbit from the ground, the larger the coverage area of ​​the non-terrestrial communication equipment, but the longer the communication delay between the non-terrestrial communication equipment and the ground terminal. Generally speaking, the orbits of non-terrestrial communication equipment are divided into the following three orbits according to the distance from the ground: low Earth orbit (LEO), medium Earth orbit (MEO), and geostationary orbit (GEO). Among them, the orbital altitude of low orbit is within the range of 160 kilometers (km)-2000km, the orbital altitude of medium orbit is within the range of 2000km-35786km, and the orbital altitude of geostationary orbit is 35786km. In addition, non-terrestrial communication equipment operating in geostationary orbit can be unaffected by the rotation of the earth.

[0093] 2. Paging message

[0094] Paging information can be used to trigger the terminal's state to transition from the IDLE state back to the connected state. Paging information can also be used to update system information (for example, earthquake and tsunami warning system (ETWS) information or commercial mobile alert system (CMAS) information). Typically, paging information is carried on the Physical Downlink Service Channel (PDSCH). If a terminal wants to normally receive paging information carried on the PDSCH, it needs to obtain the time-frequency resource location corresponding to the PDSCH in advance. The downlink control information (DCI) used to indicate the time-frequency resource location corresponding to the PDSCH is carried on the physical downlink control channel (PDCCH) scrambled by the paging-record new temporary identity (P-RNTI). That is, if the terminal wants to normally receive the paging information carried on the PDSCH, it needs to periodically listen to the PDCCH channel scrambled by the P-RNTI to receive the DCI and parse the DCI to determine the time-frequency resource location corresponding to the PDSCH. The terminal listens to and receives the paging information based on the time-frequency resource location corresponding to the PDSCH.

[0095] Optionally, the DCI used to indicate the time-frequency resource position corresponding to the PDSCH may include at least one of the following: a short message indicator, a short message, a frequency domain resource assignment, a time domain resource assignment, a virtual resource block (VRB) to a physical resource block (PRB) mapping, a modulation and coding scheme, a transport block (TB) scaling, or reserved bits. Of course, the above is only an exemplary description of DCI, and DCI may also include other information, and the embodiments of the present application do not impose any restrictions on this.

[0096] Furthermore, optionally, the network device may reserve up to 8 bits for the short information field. As shown in Table 1 below, the first bit in the short information field is used to indicate a change in system information other than system information block (SIB) 6 / 7 / 8. If the value of the first bit is 1, the first bit is used to indicate a change in system information other than SIB6 / 7 / 8 (If set to 1: indication of aBCCH modification other than SIB6, SIB7 and SIB8). The second bit in the short information field is used to indicate a change in SIB6 / 7 / 8, which is specifically used to broadcast ETWS information or CMAS information. If the value of the second bit is 1, the second bit is used to indicate a change in SIB6 / 7 / 8 (If set to 1: indication of an ETWS primary notification and / or an ETWS secondary notification and / or a CMAS notification). Bits 3-8 in the short information field are not used, and the terminal can directly ignore bits 3-8 in the short information field (Not used, and shall be ignored by UE if received).

[0097] Table 1

[0098] As mentioned above regarding "paging information", paging information can be used to trigger the terminal's state to switch from IDLE state back to connected state. Paging information can also be used to update system information (for example, ETWS information or CMAS information, etc.).

[0099] If the paging information is used to update the system information, the DCI corresponding to the paging information may include a short message, but may not include other information other than the short message in the above example (for example, frequency domain resource allocation, time domain resource allocation, virtual resource block to physical resource module mapping, modulation and coding scheme, TB scaling, and reserved bits, etc.). After the terminal receives the DCI, the terminal will receive system information (for example, SIB6 / 7 / 8, etc.) from the network device in the next modification period, and the terminal does not need to listen to and receive the paging information.

[0100] If the paging information is used to update system information, the DCI corresponding to the paging information cannot include a short message, but may include other information except the short message in the above example. After the terminal receives the DCI, the terminal parses the DCI to obtain the time-frequency resource position corresponding to the PDSCH, and receives the paging information from the network device at the time-frequency resource position corresponding to the PDSCH. The terminal parses the paging information to obtain the terminal identifier carried by the paging information, and when the terminal identifier carried by the paging information is the identifier of the terminal, determines that the network device is currently paging itself to initiate random access and then enter the connected state; when the terminal identifier carried by the paging information is not the identifier of the terminal, determines that the network device is not currently paging itself to maintain an idle state.

[0101] In addition, under normal circumstances, the frequency domain resources corresponding to the PDSCH are fixed, while the time domain resources corresponding to the PDSCH are dynamically changing. Paging information is carried on the PDSCH. Therefore, the frequency domain resources corresponding to the paging information are fixed, while the time domain resources corresponding to the paging information are dynamically changing. In order to save power consumption of the terminal, the network device will only send paging information to the terminal on a specific paging occasion (PO) in a specific paging frame (PF) within the paging cycle configured for the terminal. Correspondingly, the terminal will only listen for paging information on a specific PO in a specific PF within the paging cycle configured for the terminal. Among them, the PF includes one or more POs.

[0102] Optionally, the position of the specific PF and specific PO corresponding to the terminal is determined by performing rounding and remainder operations on the terminal identifier, the number of PFs in the paging cycle, and the number of POs in the PF. In other words, the position of the specific PF and specific PO corresponding to the terminal is related to the terminal identifier, but since the rounding and remainder may have the same value, the position of the specific PF and specific PO corresponding to different terminals may also be the same. In view of this, if the paging information is used to update the system information, then after the terminal receives the paging information on the specific PO, it is also necessary to determine whether the network device is currently paging itself based on the terminal identifier carried in the paging information.

[0103] In addition, if the paging information is used to update system information, the paging information is usually broadcast to all terminals, that is, the network device will send the paging information on the PO corresponding to all terminals, so that the terminals do not need to perform further verification on the paging information.

[0104] As mentioned above regarding "NTN," NTN offers advantages such as wide coverage, long communication distance, high reliability, great flexibility, and high throughput. Due to these advantages, NTN is often used in areas difficult to reach by terrestrial networks (e.g., oceans, forests, etc.). However, these areas may be subject to significant obstruction, which can easily block the terminal's antenna. Alternatively, users in these areas often have difficulty walking and may carry their terminals in backpacks, which can also easily block the terminal's antenna.

[0105] However, the downlink control information corresponding to the paging information usually occupies a large bandwidth, resulting in poor penetration of the downlink control information corresponding to the paging information. If the terminal is located in an area with severe antenna obstruction, it is very likely that the terminal will not be able to properly receive the downlink control information corresponding to the paging information, resulting in paging failure.

[0106] In order to avoid paging failure as much as possible, the network device can send an alarm message to the terminal device, and the alarm message can be used to indicate paging failure. After the terminal receives the alarm message, it can remind the user to move the terminal to an area where the antenna is not blocked. Since the above-mentioned alarm message occupies a smaller bandwidth than the downlink control information corresponding to the paging message, and thus has stronger penetration, after the network device reminds the terminal through the alarm message, the terminal can move to an area where the antenna is not severely blocked, so that it can normally receive the DCI corresponding to the paging information from the network device, and then can receive the paging information from the network device based on the DCI, thereby ensuring the normal progress of the paging process as much as possible, that is, helping the terminal to switch from the idle state to the connected state as much as possible or ensuring the normal transmission of service information as much as possible.

[0107] However, the above solution only records how the network device sends the alarm information. For the terminal, the terminal cannot know the time when the network device sends the alarm information, resulting in the terminal needing to continuously listen to the alarm information before receiving the alarm information, resulting in a large amount of terminal power being consumed.

[0108] Based on this, an embodiment of the present application provides an information listening method, in which the first terminal can obtain a first time domain resource for listening to the first indication information, and listen to the first indication information on the first time domain resource. In this way, the first terminal only needs to listen to the first indication information on the first time domain resource, and there is no need to continuously listen to the first indication information, thereby avoiding a large amount of power consumption of the terminal.

[0109] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0110] In order to facilitate understanding of the embodiments of the present application, the following explanations are made before introducing the embodiments of the present application.

[0111] 1. In the embodiments of the present application, for ease of description, when numbering, the numbers may be consecutively numbered starting from 1, consecutively numbered starting from 0, or starting from any parameter. It should be understood that the above are all settings for the convenience of describing the technical solution 2 provided in the embodiments of the present application, and are not intended to limit the scope of the embodiments of the present application.

[0112] 2. In the embodiment of the present application, "indication" may include direct indication and indirect indication, and may also include explicit indication and implicit indication. The information indicated by a certain information (such as the first indication information below) is called information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, wherein the other information and the information to be indicated have an association relationship. A part of the information to be indicated can also be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can also be achieved by means of the arrangement order of each piece of information agreed in advance (such as specified in the protocol), thereby reducing the indication overhead to a certain extent. At the same time, the common parts of each piece of information can also be identified and indicated uniformly to reduce the indication overhead caused by indicating the same information separately.

[0113] In addition, the specific indication method can also be various existing indication methods, such as but not limited to the above-mentioned indication methods and various combinations thereof. The specific details of the various indication methods can be referred to the prior art and will not be repeated herein. As can be seen from the above, for example, when it is necessary to indicate multiple information of the same type, there may be a situation where the indication methods for different information are different. In the specific implementation process, the required indication method can be selected according to specific needs. The embodiment of the present application does not limit the selected indication method. In this way, the indication method involved in the embodiment of the present application should be understood to cover various methods that can enable the party to be indicated to obtain the information to be indicated.

[0114] It should be understood that the information to be indicated can be sent as a whole or divided into multiple sub-information and sent separately, and the sending period and / or sending time of these sub-information can be the same or different. The specific sending method is not limited in the embodiments of this application. Among them, the sending period and / or sending time of these sub-information can be predefined, for example, predefined according to a protocol, or can be configured by the transmitting device by sending configuration information to the receiving device. Among them, the configuration information can include, for example, but not limited to, radio resource control signaling.

[0115] 3. "Pre-definition" or "pre-configuration" can be achieved by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in a device (for example, including a first terminal or a network device). The embodiments of the present application do not limit the specific implementation method. Among them, "saving" can mean saving in one or more memories. One or more memories can be set separately or integrated in an encoder or decoder, a processor, or a communication device. One or more memories can also be partially set separately and partially integrated in a decoder, a processor, or a communication device. The type of memory can be any form of storage medium, which is not limited by the embodiments of the present application.

[0116] 4. The “protocol” involved in the embodiments of the present application may refer to a standard protocol in the field of communications, for example, it may include a long term evolution (LTE) protocol, a new radio (NR) protocol, and related protocols used in future communication systems. The embodiments of the present application are not limited to this.

[0117] 5. In the embodiments of the present application, descriptions such as "when...", "in the case of...", "if" and "if" all mean that the device (such as the first terminal or network device) will make corresponding processing under certain objective circumstances. It does not limit the time, and does not require the device (such as the first terminal or network device) to perform a judgment action when implementing it, nor does it mean that there are other limitations.

[0118] 6. In the description of this application, unless otherwise specified, " / " indicates that the objects associated with each other are in an "or" relationship. For example, A / B can represent A or B. "And / or" in the embodiments of this application is a kind of association relationship that describes the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. A and B can be singular or plural. In addition, in the description of the embodiments of this application, unless otherwise specified, "multiple" refers to two or more than two. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, and c can be single or multiple. In addition, in order to facilitate the clear description of the technical solutions of the embodiments of this application, in the embodiments of this application, words such as "first" and "second" are used to distinguish between identical or similar items with basically the same functions and effects. Those skilled in the art will understand that words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit differences. At the same time, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or design. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete way for easy understanding.

[0119] The embodiments of the present application can be applied to LTE systems or NR systems (also referred to as 5G systems), vehicle to everything (V2X) systems, LTE and NR hybrid networking systems, or device to device (D2D) systems, machine to machine (M2M) communication systems, Internet of Things (IoT) systems (such as narrowband Internet of Things (NB-IoT) systems), and other next-generation communication systems. Alternatively, the communication system may also be a non-3rd Generation Partnership Project (3GPP) communication system without limitation.

[0120] In addition, the communication architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. Ordinary technicians in this field can know that with the evolution of the communication architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0121] Figure 6 is a schematic diagram illustrating a possible, non-limiting system. As shown in Figure 6, communication system 6000 includes RAN 600 and core network 700. RAN 600 includes at least one RAN node (e.g., 610a and 610b in Figure 6, collectively referred to as 610) and at least one terminal (e.g., 620a-620j in Figure 6, collectively referred to as 620). RAN 600 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment (not shown in Figure 6). Terminal 620 is wirelessly connected to RAN node 610. RAN node 610 is wirelessly or wiredly connected to core network 700. The core network equipment in core network 700 and RAN node 610 in RAN 600 may be separate physical devices, or they may be the same physical device that integrates core network logical functions and radio access network logical functions.

[0122] The RAN 600 may be a 3GPP-related cellular system, such as a 4G or 5G mobile communication system, or a future-oriented evolutionary system (such as a 6G mobile communication system). The RAN 600 may also be an open access network (O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless fidelity (WiFi) system. The RAN 600 may also be a communication system that integrates two or more of the above systems.

[0123] For example, taking RAN 600 as an O-RAN, as shown in FIG7 , the O-RAN may include a gNB-CU or gNB-DU, and an intelligent controller (RAN intelligent controller, RIC). The RIC is used to collect network information and perform necessary optimization tasks. The RIC can communicate with the gNB-CU or gNB-DU via the E2 interface and / or the F1 interface. Specifically, the RIC can communicate with the gNB-DU via the E2 interface, and the RIC can communicate with the gNB-DU via the E2 interface, and can also communicate with the gNB-DU via the E2 interface, the F1 interface, and the gNB-CU. The gNB-CU or gNB-DU can communicate with the terminal.

[0124] The RAN node 610, which may also sometimes be referred to as access network equipment, RAN entity or access node, etc., constitutes a part of the communication system to help terminals achieve wireless access. The multiple RAN nodes 610 in the communication system 6000 may be nodes of the same type or different types. In some scenarios, the roles of the RAN node 610 and the terminal 620 are relative. For example, the network element 620i in Figure 6 may be a helicopter or a drone, which may be configured as a mobile base station. For those terminals 620j that access the RAN 600 through the network element 620i, the network element 620i is a base station; but for the base station 610a, the network element 620i is a terminal. The RAN node 610 and the terminal 620 are sometimes referred to as communication devices. For example, the network elements 610a and 610b in Figure 6 may be understood as communication devices with base station functions, and the network elements 620a-620j may be understood as communication devices with terminal functions.

[0125] In one possible scenario, a RAN node can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a gNB, a next-generation base station in a sixth-generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. A RAN node can be a macro base station (such as 610a in Figure 6 ), a micro base station or an indoor station (such as 610b in Figure 6 ), a relay node or a donor node, or a wireless controller in a CRAN scenario. Alternatively, a RAN node can be a server, a wearable device, a vehicle, or an onboard device. For example, the access network device in vehicle-to-everything (V2X) technology can be a roadside unit (RSU).

[0126] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, and different RAN nodes implement part of the functions of the base station respectively. For example, the RAN node can be a CU, DU, CU-control plane (CP), CU-user plane (UP), or radio unit (RU). The CU and DU can be set separately, or they can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0127] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (Open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application uses CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0128] For a terminal, in one possible scenario, the terminal may be a device for implementing wireless communication functions, such as a terminal or a chip that can be used in a terminal, etc. The terminal may be a user equipment (UE), an access terminal, a terminal unit, a terminal station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a wireless communication device, a terminal agent, or a terminal device, etc. in a 5G network or a future evolved public land mobile network (PLMN). The access terminal may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device or a wearable device, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical care, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, etc. In one possible implementation, the terminal may be mobile or fixed.

[0129] In a possible implementation, the network device and terminal in the embodiment of the present application may also be referred to as a communication device, which may be a general device or a dedicated device, and the embodiment of the present application does not specifically limit this.

[0130] In one possible implementation, the relevant functions of the terminal or network device in the embodiments of the present application can be implemented by a single device, or by multiple devices together, or by one or more functional modules within a single device, and the embodiments of the present application do not specifically limit this. It is understood that the above functions can be network elements in hardware devices, software functions running on dedicated hardware, a combination of hardware and software, or virtualized functions instantiated on a platform (e.g., a cloud platform).

[0131] Optionally, the communication system 6000 may further include the Internet 800. Exemplarily, the Internet 800 may be a DN.

[0132] It should be noted that since the method described in the embodiment of the present application may be applied not only to the terrestrial network, but also to the NTN, specifically, the method described in the embodiment of the present application can be specifically applied to the NTN-based 5G network shown in Figures 1 to 5 above, the communication system described in the embodiment of the present application can be adaptively changed with reference to the network architecture shown in Figures 1 to 5 above, and will not be repeated here.

[0133] For example, the relevant functions of the terminal or network device in the embodiments of the present application can be implemented by the communication device 810 in Figure 8. Figure 8 shows a schematic diagram of the structure of a possible communication device. It is understood that the communication device 810 includes necessary means such as modules, units, elements, circuits, or interfaces, which are appropriately configured together to implement the present solution. The communication device 810 can be the RAN node, terminal, core network device, or other network device in Figure 6, or a component (such as a chip) in these devices, used to implement the methods described in the following method embodiments. The communication device 810 includes one or more processors 811 and a transceiver 815. The processor 811 can be a general-purpose processor or a dedicated processor. For example, it can be a baseband processor or a central processing unit. The baseband processor can be used to process communication protocols and communication data, and the central processing unit can be used to control the communication device (such as a RAN node, terminal, or chip), execute software programs, and process software program data. The processor 811 is sometimes also referred to as a processing unit, which controls the communication device (such as a RAN node or terminal). The transceiver 815 may also sometimes be referred to as a transceiver unit, a transceiver, a transceiver circuit, or a transceiver, etc., and is used to implement the transceiver function of the communication device through the antenna 816.

[0134] Optionally, in one design, the processor 811 may include a program 813 (sometimes also referred to as code or instructions), which may be executed on the processor 811 to cause the communication device 810 to perform the methods described in the following embodiments. In yet another possible design, the communication device 810 includes a circuit (not shown in FIG8 ) configured to implement the information interception functionality described in the following embodiments.

[0135] Optionally, the communication device 810 may include one or more memories 812 on which a program 814 (sometimes also referred to as code or instructions) is stored. The program 814 can be run on the processor 811 so that the communication device 810 performs the method described in the following method embodiment.

[0136] Optionally, the processor 811 and / or the memory 812 may include AI modules 817 and 818, which are used to implement AI-related functions. The AI ​​module may be implemented using software, hardware, or a combination of software and hardware. For example, the AI ​​module may include a real-time information processing (RIC) module. For example, the AI ​​module may be a near-real-time RIC or a non-real-time RIC.

[0137] Optionally, data may be stored in the processor 811 and / or the memory 812. The processor and the memory may be provided separately or integrated together.

[0138] Optionally, the communication device 810 may further include an antenna 816 .

[0139] The information interception method provided in the embodiment of the present application will be described in detail below with reference to FIG9 .

[0140] It should be noted that in the following embodiments of the present application, the names of the information between the various network elements, the names of the various parameters, or the names of the various information are only examples. In other embodiments, they may also be other names, and the methods provided in the embodiments of the present application are not specifically limited to this. It is understandable that in the embodiments of the present application, each network element may perform some or all of the steps in the embodiments of the present application. These steps or operations are examples, and the embodiments of the present application may also perform other operations or variations of various operations. In addition, the various steps may be performed in a different order than those presented in the embodiments of the present application, and it may not be necessary to perform all of the operations in the embodiments of the present application.

[0141] Figure 9 is an example of an information interception method provided by an embodiment of the present application. The method is illustrated by taking the interaction between the first terminal and the network device as an example. Of course, the subject that executes the action of the first terminal in the method can also be a device / module in the first terminal, such as a chip, processor, processing unit, etc. in the first terminal, and the subject that executes the action of the network device in the method can also be a device / module in the network device, such as a chip, processor, processing unit, etc. in the network device. The embodiment of the present application does not make specific limitations on this. For example, as shown in Figure 9, the information interception method includes the following steps:

[0142] S901. A first terminal obtains a first time domain resource.

[0143] The first time domain resource is a time domain resource for the first terminal to monitor the first indication information. The first indication information is used to indicate a paging failure.

[0144] It can be understood that the first indication information is used to indicate paging failure, which can be understood as the antenna of the first terminal being blocked, or the signal quality of the first terminal being poor, or the signal quality of the first terminal needing to be improved, or the first terminal wants to establish a connection with the communication network but cannot establish a connection with the communication network. The embodiments of the present application do not impose any restrictions on this.

[0145] For example, the time domain resources described in the embodiments of the present application may be at least one frame, at least one time slot, or at least one orthogonal frequency division multiplexing (OFDM) symbol. Of course, the above is only an exemplary description of the time domain resources described in the embodiments of the present application. The time domain resources described in the embodiments of the present application may also be other time domain resources, and the embodiments of the present application do not impose any restrictions on this.

[0146] S902. The network device sends first indication information to the first terminal on a first time domain resource.

[0147] It should be noted that, before S902, the network device can normally send paging information of the first terminal according to the preconfigured paging cycle. In the event of a paging failure, the network device generates first indication information and sends the first indication information to the first terminal on the first time domain resource. The paging information of the first terminal refers to the paging information used to paging the first terminal.

[0148] Optionally, if the first time domain resource is a time domain resource shared by multiple terminals, the network device may further send the first indication information to the multiple terminals respectively on the first time domain resource. This embodiment of the present application does not impose any limitation on this.

[0149] Exemplarily, the network device described in the embodiments of the present application may be a terrestrial access network device, a non-terrestrial access network device, a non-terrestrial satellite that serves only as a transparent forwarding unit, a non-terrestrial satellite that has only a gNB-DU function, or a non-terrestrial satellite that has only a gNB-DU function and an IAB function. The relevant descriptions of terrestrial access network devices, non-terrestrial access network devices, non-terrestrial satellites that serve only as transparent forwarding units, non-terrestrial satellites that have only a gNB-DU function, and non-terrestrial satellites that have only a gNB-DU function and an IAB function can be understood by referring to the descriptions of the corresponding positions above, and will not be repeated here. Of course, the above is only an exemplary description of the network device described in the embodiments of the present application. The network device described in the embodiments of the present application may also be other communication devices, and the embodiments of the present application do not impose any restrictions on this.

[0150] S903: The first terminal listens for first indication information on a first time domain resource.

[0151] In an embodiment of the present application, the first terminal can obtain a first time domain resource for listening to the first indication information, and listen to the first indication information on the first time domain resource. In this way, the first terminal only needs to listen to the first indication information on the first time domain resource, and does not need to continuously listen to the first indication information, thereby avoiding a large amount of power consumption of the terminal.

[0152] The first time domain resource is described below.

[0153] In one possible implementation, the first time domain resource includes at least one time domain resource in a first time domain resource set, the first time domain resource set includes time domain resources shared by multiple terminals for listening to first indication information, and the multiple terminals include the first terminal. That is, the first terminal can share the time domain resources for listening to the first indication information with other terminals, so that resource utilization can be improved as much as possible.

[0154] Further, optionally, in this case, the network device may determine the first time domain resource by summing up the time domain resources that can be occupied by multiple terminals and allocating the time domain resources that can be occupied by multiple terminals based on the type of information to determine the first time domain resource. Exemplarily, assuming that the time domain resources that can be occupied by multiple terminals include time domain resources 1 to time domain resources 5, the network device may allocate time domain resources 1 to time domain resources 3 for the first indication information. In other words, the first time domain resources include time domain resources 1 to time domain resources 3.

[0155] In another possible implementation, the first time domain resource includes at least one time domain resource in the second time domain resource set, and the second time domain resource set includes a time domain resource allocated to the first terminal for listening to the first indication information. That is, different terminals have their own corresponding time domain resources for listening to the first indication information. For example, the time domain resource for the terminal to listen to the first indication information is related to the terminal's identifier (for example, a temporary mobile station identifier (TMSI)). In this way, conflicts in the process of each terminal listening to the first indication information can be avoided as much as possible, thereby ensuring that each terminal can listen to the first indication information normally as much as possible.

[0156] Further, optionally, in this case, the implementation process of the network device determining the first time domain resource may include: the network device may determine the time domain resources that the first terminal can occupy, and allocate the time domain resources that the first terminal can occupy based on the type of information to determine the first time domain resource. Exemplarily, assuming that the time domain resources that the first terminal can occupy include time domain resources 6 to time domain resources 8: the network device may allocate time domain resources 6 and time domain resources 7 for the first indication information, that is, the first time domain resources include time domain resources 6 and time domain resources 7.

[0157] Optionally, in this case, the implementation process of the network device determining the first time domain resources can also be: the network device can determine the time domain resources that can be occupied by the first terminal, and determine the first time domain resources from the time domain resources that can be occupied by the first terminal based on the identifier of the first terminal, the number of PFs in the time domain resources that can be occupied by the first terminal, and the number of POs in the PF.

[0158] In another possible implementation, the first time domain resource includes at least one time domain resource in the third time domain resource set, and the third time domain resource set includes the time domain resource allocated to the first terminal for listening to paging information. The first terminal can reuse the time domain resource corresponding to the first terminal for listening to paging information to listen to the first indication information. In this way, there is no need to separately configure time domain resources for the first indication information, and conflicts in the process of each terminal listening to the first indication information are avoided as much as possible. Therefore, while saving time domain resources, it is also guaranteed as much as possible that each terminal can listen to the first indication information normally.

[0159] Further, optionally, in this case, the network device may determine the first time domain resource by: the network device may determine the time domain resources available for the first terminal, and allocate the time domain resources available for the first terminal based on the type of information to determine the first time domain resource. Exemplarily, assuming that the time domain resources available for the first terminal include time domain resources 9 to time domain resources 11, the network device may allocate time domain resources 9 to time domain resources 11 for the paging information. In other words, the first time domain resources include time domain resources 9 to time domain resources 11.

[0160] In addition, the network device may also determine the first time resource based on the aforementioned implementation method of the network device determining the PF and PO for monitoring paging information, which will not be described in detail here.

[0161] It should be pointed out that in this implementation method, the first terminal can listen to the first indication information on the time domain resources used to listen to paging information. In this way, after the first terminal listens to and receives the information on the first time domain resources, it parses and processes the above information normally, and determines that the above information is the first indication information or paging information through the information content obtained by parsing.

[0162] Of course, the above is only an exemplary description of the network device determining the first time domain resource. The network device can also determine the first time domain resource from the time domain resources that can be occupied by the first terminal in other ways. The embodiment of the present application does not impose any restrictions on this.

[0163] The following describes an implementation method in which the first terminal obtains the first time domain resource as described in S901 above.

[0164] Optionally, the first terminal may obtain the first time domain resource in the following two ways: Method 1 is that the first terminal obtains the first time domain resource from another device; Method 2 is that the first terminal independently determines the first time domain resource. Of course, the above is only an exemplary description of the implementation method for the first terminal to obtain the first time domain resource. The first terminal may also obtain the first time domain resource in other ways, and this embodiment of the application does not impose any limitation on this.

[0165] The following is a detailed description of the above methods 1 and 2:

[0166] Method 1 is that the first terminal obtains the first time domain resource from other devices. As shown in FIG10 , in method 1, the above S901 can be implemented through S1001.

[0167] S1001. A network device sends second indication information to a first terminal. Correspondingly, the first terminal receives the second indication information from the network device.

[0168] The second indication information is used to indicate the first time domain resource.

[0169] It is understandable that the first terminal can obtain the second indication information for indicating the first time domain resource from the network device, so that the first terminal can directly obtain the first time domain resource through the second indication information, thereby saving the computational burden of the first terminal in determining the first time domain resource.

[0170] In the second approach, the first terminal determines the first time domain resource by itself. As shown in FIG10 , in the second approach, the above S901 can be implemented through S1002 .

[0171] S1002. The first terminal determines a first time domain resource according to preconfigured time domain resource allocation information.

[0172] In one possible implementation, the preconfigured time domain resource allocation information may be used to indicate the time domain resource corresponding to each indication information. In this case, the first terminal may determine the time domain resource corresponding to the first indication information based on the preconfigured time domain resource allocation information, and determine the time domain resource corresponding to the first indication information as the first time domain resource.

[0173] In another possible implementation, the preconfigured time domain resource allocation information may be used to indicate the time domain resources corresponding to each terminal and / or the time domain resources corresponding to each indication information. In this case, the first terminal may determine the time domain resources corresponding to the first terminal based on the time domain resources corresponding to each terminal indicated by the preconfigured time domain resource allocation information, and determine the time domain resources corresponding to the first indication information based on the time domain resources corresponding to each indication information indicated by the preconfigured time domain resource allocation information. The first terminal determines the overlapping time domain resources between the time domain resources corresponding to the first terminal and the time domain resources corresponding to the first indication information as the first time domain resources.

[0174] In another possible implementation, the preconfigured time domain resource allocation information may be used to indicate the time domain resources corresponding to each terminal and / or the time domain resources corresponding to each indication information. In this case, the first terminal may determine the time domain resources corresponding to the first terminal based on the time domain resources corresponding to each terminal indicated by the preconfigured time domain resource allocation information, and determine the time domain resources corresponding to the paging information based on the time domain resources corresponding to each indication information indicated by the preconfigured time domain resource allocation information. The first terminal determines the overlapping time domain resources between the time domain resources corresponding to the first terminal and the time domain resources corresponding to the paging information as the first time domain resources.

[0175] In another possible implementation, the preconfigured time domain resource allocation information may be used to indicate a method for determining the first time domain resource. In this case, the first terminal may determine the first time domain resource based on the method for determining the first time domain resource and the parameters required by the method. For example, if the preconfigured time domain resource allocation information indicates that the method for determining the first time domain resource is a specific algorithm, the first terminal may determine the first terminal's identifier as the parameter required by the algorithm and process the first terminal's identifier using the specific algorithm to determine the first time domain resource.

[0176] Optionally, the identifier of the first terminal can be a permanent identifier (for example, a user permanent identifier (SUPI), a general public subscription identifier (GPSI)), and the identifier of the first terminal can also be a temporary identifier (for example, a temporary mobile station identity (TMSI)). The embodiments of the present application do not impose any restrictions on this.

[0177] It can be understood that in addition to directly obtaining the first time domain resource, the first terminal can also determine the first time domain resource based on the pre-configured time domain resource allocation information. In this way, when the network device is unable to provide the first time domain resource for the first terminal, the first terminal can also determine the first time domain resource by itself based on the pre-configured time domain resource allocation information. In other words, another implementation method for obtaining the first time domain resource is provided, thereby improving the reliability of the first terminal in determining the first time domain resource.

[0178] Optionally, the first terminal can be informed of the paging failure through the first indication information intercepted, so that the first terminal can remind the user to place the first terminal in an area where the antenna is not severely blocked, so that the first terminal can subsequently receive the paging information from the network device, so that the paging process can proceed normally. In other words, the role of the first indication information is still to ensure that the paging process of the first terminal can proceed normally. In view of this, an embodiment of the present application provides another information interception method to intercept paging information, as shown in Figure 11, the information interception method includes the following steps:

[0179] S1101. A network device determines a third time domain resource.

[0180] The third time domain resource includes a time domain resource for the network device to send paging information of the first terminal.

[0181] It should be noted that the above-mentioned third time domain resources may include at least one time domain resource for the network device to send paging information of the first terminal. That is to say, the embodiment of the present application does not impose any restriction on the number of time domain resources included in the third time domain resources.

[0182] In a possible implementation, the third time domain resource may include at least one paging cycle, so that the network device may periodically send paging information of the first terminal within the at least one paging cycle.

[0183] In another possible implementation, the third time domain resource may be a limited number of time domain resources, such that the network device sends the paging information of the first terminal within the limited number of time domain resources. Furthermore, if the network device fails to send the paging information of the first terminal after sending the paging information of the first terminal within the third time domain resource, the network device stops sending the paging information of the first terminal, thereby avoiding the increase in energy consumption and signaling overhead caused by the network continuously sending the paging information of the first terminal.

[0184] Furthermore, in this implementation, in one example, the limited number of time domain resources includes multiple time domain resources after the first time domain resource, so that the network device can send the paging information of the first terminal on the multiple time domain resources respectively.

[0185] In another example, the limited number of time domain resources is a time domain resource after the fifth time domain resource, so that the network device can send paging information of the first terminal on the time domain resource, wherein the fifth time domain resource is after the first time domain resource and is separated from the first time domain resource by at least one time domain resource.

[0186] Of course, the above is only an exemplary description of the third time domain resource. The network device can also set the third time domain resource through other methods, and the embodiment of the present application does not impose any limitation on this.

[0187] S1102. The network device sends paging information of the first terminal on a third time domain resource.

[0188] Optionally, the network device may send the paging information of the first terminal on the third time domain resource in the form of a broadcast. Of course, the above is only an exemplary description of the implementation process of the network device sending the paging information of the first terminal on the third time domain resource. The network device may also send the paging information of the first terminal on the third time domain resource in other ways, and the embodiments of the present application do not impose any restrictions on this.

[0189] In addition, if the network device sends the first indication information to multiple terminals respectively, the network device can send paging information for each of the multiple terminals, and can also send paging information for the terminals among the multiple terminals that need to switch back to the connected state. This embodiment of the present application does not impose any restrictions on this. In other words, the network device can adaptively send paging information for the terminals that need to switch back to the connected state, so that the terminals that need to switch back to the connected state can initiate a random access process based on the paging information and then switch back to the connected state, thereby avoiding redundant operations for terminals that do not need to switch back to the connected state.

[0190] It should be noted that after S1102, if the state of the first terminal still cannot be converted back to the connected state, the network device will not continue to send paging information to save signaling overhead and also save the power consumption of the first terminal continuously listening to paging information.

[0191] S1103. The first terminal obtains a second time domain resource.

[0192] The second time domain resource includes a time domain resource after the first time domain resource, in which the first terminal monitors the paging information.

[0193] It should be noted that the above-mentioned second time domain resources may include at least one time domain resource after the first time domain resource, in which the first terminal listens to the paging information. That is, the embodiment of the present application does not impose any restriction on the number of time domain resources included in the second time domain resources.

[0194] It should be noted that, in the case where the first terminal can obtain the time domain resource (i.e., the third time domain resource) in which the network device sends the paging information of the first terminal, the third time domain resource and the second time domain resource can be the same time domain resource, so that the first terminal can normally listen to the paging information of the first terminal sent by the network device. However, in the case where the first terminal may not be able to obtain the time domain resource in which the network device sends the paging information of the first terminal, the first terminal cannot set the third time domain resource as the second time domain resource and can only determine the second time domain resource by itself. However, in this case, there needs to be an overlapping part between the third time domain resource and the second time domain resource so that the first terminal can normally listen to the paging information of the first terminal sent by the network device.

[0195] It should be noted that the embodiment of the present application does not limit the execution order between S901, S1101, and S1103. The execution order shown in Figure 11 is only an example, and the present application does not impose any restrictions on this.

[0196] S1104. The first terminal listens to paging information on the second time domain resources.

[0197] It is understandable that after the first time domain resource, the first terminal can be informed of the paging failure through the first indication information heard, and then the first terminal can remind the user to place the first terminal in an area where the antenna is not severely blocked, that is, in the subsequent process, the first terminal can receive the paging information normally. In view of this, the first terminal can obtain the second time domain resource for listening to the paging information, and listen to the paging information on the second time domain resource, so that the first terminal only needs to listen to the paging information on the second time domain resource to obtain the paging information normally, without the need to continuously listen to the paging information, thereby saving the power of the first terminal while enabling the state of the first terminal to be switched from the idle state to the connected state.

[0198] It should be noted that before the first terminal listens to the paging information on the second time domain resource, the first terminal can pre-determine whether it needs to listen to the paging information on the second time domain resource, so that the first terminal can listen to the paging information when appropriate to avoid unnecessary consumption of the power of the first terminal.

[0199] Optionally, the first terminal may determine whether it needs to listen to paging information on the second time domain resources in the following two ways: In the third way, the first terminal determines whether it needs to listen to paging information on the second time domain resources based on the signal quality of the terminal device; in the fourth way, the access stratum (AS) of the first terminal determines whether it needs to listen to paging information on the second time domain resources based on the indication information obtained from the upper layer of the AS of the first terminal. Of course, the above is only an exemplary description of the implementation method of the first terminal determining whether it needs to listen to paging information on the second time domain resources. The first terminal may also determine whether it needs to listen to paging information on the second time domain resources in other ways, and the embodiments of the present application do not impose any restrictions on this.

[0200] The following is a detailed description of the above-mentioned method 3 and method 4:

[0201] Mode 3 is that the first terminal determines whether it needs to listen to paging information on the second time domain resource according to the signal quality of the terminal device. As shown in FIG12 , in Mode 3, the implementation process of the first terminal determining whether it needs to listen to paging information on the second time domain resource may include the following S1201.

[0202] S1201: When the signal quality of the first terminal is greater than a first threshold, the first terminal determines that it needs to listen to paging information on a second time domain resource.

[0203] Exemplarily, the signal quality may include at least one of the following: reference signal receiving power (RSRP), reference signal received quality (RSRQ), or signal to interference plus noise ratio (SINR). Of course, the above is only an exemplary description of signal quality, and the signal quality may also include other information, which is not limited in the embodiments of the present application.

[0204] Optionally, the first threshold value may be set by the network device based on actual network conditions. For example, the network device may set the first threshold value to -85 decibels per milliwatt (dBm). Of course, the above is only an exemplary description of the first threshold value. The first threshold value may also be other values, and the embodiments of the present application do not impose any limitation on this.

[0205] It can be understood that when the signal quality of the first terminal is good, the first terminal has the ability to normally receive paging information, so it is determined that it is necessary to listen to the paging information on the second time domain resources, thereby avoiding the situation where the first terminal does not have the ability to normally receive paging information, causing the first terminal to listen to the paging information, thereby avoiding the first terminal's power being consumed by redundant operations.

[0206] In mode 4, the AS of the first terminal determines whether it needs to listen for paging information on the second time domain resource based on the indication information obtained from the upper layer of the AS of the first terminal. As shown in Figure 12, in mode 4, the implementation process of the first terminal determining whether it needs to listen for paging information on the second time domain resource may include the following S1202 to S1203.

[0207] S1202. The upper layer of the AS of the first terminal sends fifth indication information to the AS of the first terminal. Correspondingly, the AS of the first terminal receives the fifth indication information from the upper layer of the AS of the first terminal.

[0208] The fifth indication information is used to instruct the first terminal to listen to the paging information.

[0209] Exemplarily, the upper layer of the AS of the first terminal may be the non-access stratum (NAS) of the first terminal. Of course, the above is only an exemplary description of the upper layer of the AS of the first terminal. The upper layer of the AS of the first terminal may also be other layers of the first terminal, and the embodiments of the present application do not impose any restrictions on this.

[0210] Optionally, if after the first terminal receives the first indication information, the first terminal will perform a ringing operation to remind the user to place the first terminal in an area where the antenna is not severely blocked, so that the first terminal can subsequently receive paging information normally, then the upper layer of the AS of the first terminal can generate a fifth indication information in response to the user's cancel ringing operation to instruct the first terminal to listen to the paging information.

[0211] S1203. The AS of the first terminal determines, according to the fifth indication information, that it needs to listen to paging information on the second time domain resources.

[0212] It can be understood that if the AS of the first terminal receives the fifth indication information for instructing to listen to the paging information, the first terminal will determine that it needs to listen to the paging information on the second time domain resources, thereby avoiding the first terminal listening to the paging information when the first terminal does not have the ability to normally receive the paging information, thereby avoiding the first terminal's power being consumed by redundant operations.

[0213] In a possible implementation, the first terminal may also determine whether it is necessary to listen to the first indication information on the first time domain resource by the method described in the above-mentioned method three and method four. Specifically, the first terminal determines that it is necessary to listen to the first indication information on the first time domain resource when the signal quality of the first terminal is less than or equal to the first threshold; or, the AS of the first terminal determines that it is necessary to listen to the first indication information on the first time domain resource based on the indication information indicating that the antenna is blocked obtained from the upper layer of the AS of the first terminal. The relevant description of the first terminal determining whether it is necessary to listen to the first indication information on the first time domain resource by the method described in the above-mentioned method three and method four can be understood by referring to the relevant description of the first terminal determining whether it is necessary to listen to the paging information on the second time domain resource by the method described in the above-mentioned method three and method four, and will not be repeated here.

[0214] Optionally, the first terminal can obtain the second time domain resource through the following two methods: Method 5 is that the first terminal obtains the second time domain resource from another device; Method 6 is that the first terminal independently determines the second time domain resource. Of course, the above is only an exemplary description of the implementation method of the first terminal obtaining the second time domain resource. The first terminal can also obtain the second time domain resource through other methods, and this embodiment of the application does not impose any restrictions on this.

[0215] The following is a detailed description of the above methods 5 and 6:

[0216] Mode 5 is that the first terminal obtains the second time domain resource from other devices. As shown in FIG13 , in Mode 5, the above S1103 can be implemented through S1301.

[0217] S1301. A network device sends third indication information to a first terminal. Correspondingly, the first terminal receives the third indication information from the network device.

[0218] The third indication information is used to indicate the second time domain resource.

[0219] Optionally, the network device may send the second indication information and the third indication information at the same time, or may send the second indication information and the third indication information separately. This embodiment of the present application does not impose any restrictions on this.

[0220] It is understandable that the first terminal can obtain the third indication information for indicating the second time domain resource from the network device, so that the first terminal can directly obtain the second time domain resource through the third indication information, thereby saving the computational burden of the first terminal in determining the second time domain resource.

[0221] Mode 6 is that the first terminal determines the second time domain resource by itself. As shown in FIG13 , in Mode 6, the above S1103 can be implemented through S1302.

[0222] S1302. The first terminal determines a second time domain resource based on the first time domain resource and / or the preset time domain resource.

[0223] It can be understood that in addition to directly obtaining the second time domain resources, the first terminal can also determine the second time domain resources based on the first time domain resources and / or the preset time domain resources. In this way, when the network device is unable to provide the second time domain resources for the first terminal, the first terminal can also determine the second time domain resources based on the first time domain resources and / or the preset time domain resources. In other words, another implementation method for obtaining the second time domain resources is provided, thereby improving the reliability of the first terminal in determining the second time domain resources.

[0224] In one possible implementation, the preset time domain resource is preconfigured. For example, the preset time domain resource can be determined by the first terminal according to the actual network situation. The embodiment of the present application does not impose any restrictions on this. In this case, the implementation process of S1302 can be: the first terminal uses the time when the signal quality is greater than the first threshold or the time when the AS layer receives the fifth indication information as the starting time domain resource, or the first terminal can also use a time domain resource after the first time domain resource (for example, the first time domain resource after the first time domain resource) as the starting time domain resource, and determine it as the second time domain resource based on the starting time domain and the preset time domain resource. Specifically, the second time domain resource can be the preset time domain resource after the starting resource.

[0225] However, the second time domain resource including multiple time domain resources can also be understood as the first terminal will continue to listen to the paging information for a period of time. In addition, optionally, if the first terminal still does not receive the paging information after listening to the paging information for a period of time, it stops listening to the paging information.

[0226] In another possible implementation, the preset time domain resource may be determined based on a dynamically changing time domain resource. For example, the preset time domain resource may be determined based on a third time domain resource and / or a fourth time domain resource. The fourth time domain resource includes the time domain resource between the first time domain resource and the time domain resource used by the network device to send paging information for the first terminal. In this case, the implementation process of S1302 may be: the first terminal may directly determine the preset time domain resource as the second time domain resource.

[0227] Further, optionally, the implementation process of S1302 may be: the first terminal may directly determine the third time domain resource as the preset time domain resource.

[0228] Optionally, the implementation process of S1302 may be: the first terminal may use the first time domain resource after the first time domain resource as the starting time domain resource, and determine the preset time domain resource based on the above starting time domain resource and the fourth time domain resource.

[0229] It can be understood that the third time domain resource and the fourth time domain resource are both time domain resources related to the time domain resources of the network device sending the paging information of the first terminal. The first terminal determines the preset time domain resource based on the third time domain resource and / or the fourth time domain resource, so that the preset time domain resource is also related to the time domain resource of the network device sending the paging information of the first terminal. In this way, the second time domain resource determined based on the preset time domain resource can be closer to the time domain resource of the network device sending the paging information of the first terminal. That is to say, the overlap between the above-mentioned second time domain resource and the time domain resource of the network device sending the paging information of the first terminal can be increased as much as possible, thereby ensuring that the first terminal can hear the paging information on the second time domain resource as much as possible.

[0230] Of course, the above is only an exemplary description of the first terminal determining the preset time domain resources and the second time domain resources. The first terminal can also determine the preset time domain resources or the second time domain resources according to other methods, and the embodiments of the present application do not impose any restrictions on this.

[0231] In addition, in order for the first terminal to obtain the third time domain resource, so that the first terminal can determine the preset time domain resource based on the third time domain resource, and determine the second time domain resource based on the preset time domain resource, as shown in FIG13, the information monitoring method further includes the following steps:

[0232] S1303: The network device sends fourth indication information to the first terminal. Correspondingly, the first terminal receives the fourth indication information from the network device.

[0233] The fourth indication information is used to indicate the third time domain resource and / or the fourth time domain resource.

[0234] It is understandable that the first terminal can obtain fourth indication information for indicating the third time domain resources and / or the fourth time domain resources from the network device, so that the first terminal can directly obtain the third time domain resources through the fourth indication information, so that the first terminal can subsequently determine the preset time domain resources based on the third time domain resources, thereby providing effective data preparation.

[0235] As described above, the methods shown in Figures 11 to 13 are all performed on the basis that the network device will also send the paging information of the first terminal after sending the first indication information. However, the network device may also not send the paging information of the first terminal after sending the first indication information. However, in this case, the first terminal may also initiate a random access process to the network device so that the state of the first terminal can be changed from the idle state to the connected state. In view of this, another information listening method provided in an embodiment of the present application is shown in Figure 13, and the information listening method includes the following steps:

[0236] S1304: When the first indication information is also used to indicate paging reason information, the first terminal initiates a random access procedure to the network device. Correspondingly, the network device responds to the random access procedure initiated by the first terminal.

[0237] The paging reason information is used to indicate that the paging information of the first terminal is triggered by a voice service.

[0238] It can be understood that if the first indication information is also used to indicate the paging reason information, it means that the network device will not send the paging information again, so that the first terminal can directly initiate the random access process, so that when the network device no longer resends the paging, the first terminal can still change the state of the first terminal from the idle state back to the connected state.

[0239] In addition, if the antenna of the first terminal is severely blocked after the first terminal receives the short message, it is very likely that the first terminal receives the short message but cannot receive the system information, which in turn causes the first terminal's system information to be unable to be updated normally. In order to enable the first terminal's system information to be updated normally as much as possible, in view of this, an embodiment of the present application provides another information monitoring method, as shown in Figure 14, which includes the following steps:

[0240] S1401. When the first terminal receives a short message but cannot receive system information, the AS of the first terminal sends sixth indication information to the upper layer of the AS of the first terminal. Correspondingly, the upper layer of the AS of the first terminal receives the sixth indication information from the AS of the first terminal.

[0241] The sixth indication information is used for failure to receive system information, and the short message is used to indicate changes in system information.

[0242] For example, the system information may be SIB6, SIB7, or SIB8. Of course, the above is only an exemplary description of the system information, and the system information recorded in the embodiment of the present application may also be other system information, and the embodiment of the present application does not impose any limitation on this.

[0243] In one possible implementation, the upper layer of the AS of the first terminal instructs the first terminal to perform a ringing operation to remind the user to place the first terminal in an area where the antenna is not severely blocked, so that the first terminal can subsequently receive system information normally.

[0244] Optionally, when the AS of the first terminal determines that the signal quality is greater than the first threshold or the AS of the first terminal receives indication information from an upper layer of the AS of the first terminal, and the indication information is used to instruct to listen to system information, the first terminal may listen to and receive system information from the network device. The implementation method of the first terminal re-listening to and receiving system information from the network device can be understood by referring to the relevant description of the above-mentioned method three and method four, and will not be repeated here.

[0245] It should be understood that the system information and short messages can be understood by referring to the descriptions of the corresponding positions above, which will not be repeated here.

[0246] It should be pointed out that the method recorded in Figure 14 can be combined with the method shown in Figures 9 to 13 above, or it can not be combined with the method shown in Figures 9 to 13 above, that is, it exists alone, and the embodiments of the present application do not impose any restrictions on this.

[0247] It is understandable that after the first terminal receives the short message, if the antenna of the first terminal is severely blocked, it is very likely that the first terminal will not receive the system information, and thus the system information of the first terminal needs to be updated but cannot be updated normally. In this case, the AS of the first terminal can send sixth indication information to the upper layer of the AS of the first terminal. The sixth indication information is used for the failure to receive the system information. In this way, the upper layer of the AS of the first terminal can be informed of the failure to receive the system information, so that the upper layer of the AS of the first terminal can remind the user to move the first terminal to an area where the antenna is not severely blocked, thereby enabling the system information update process to proceed normally.

[0248] It should be noted that the methods illustrated in Figures 9 to 14 above are all described using a common base station as an example. However, the network device can also be an O-RAN. As previously mentioned regarding "O-RAN," an O-RAN can include a gNB-CU or gNB-DU, as well as an RIC. The following describes an information interception method for an O-RAN network device. Therefore, as shown in Figure 15, the information interception method includes the following steps:

[0249] S1501. The RIC sends the seventh indication information to the gNB-CU or gNB-DU through the E2 interface and / or the F1 interface. Correspondingly, the gNB-CU or gNB-DU receives the seventh indication information from the RIC through the E2 interface and / or the F1 interface.

[0250] The seventh indication information is used to instruct the gNB-CU or gNB-DU to send the second indication information to the first terminal.

[0251] As mentioned above regarding "O-RAN," the RIC can communicate with the gNB-CU or gNB-DU via the E2 interface and / or the F1 interface. Specifically, the RIC can communicate with the gNB-DU via the E2 interface, and the RIC can communicate with the gNB-DU via the E2 interface, or can communicate with the gNB-DU via the E2 interface, the F1 interface, and the gNB-CU. In other words, the RIC can send the seventh indication information to the gNB-DU via the E2 interface, and the RIC can send the seventh indication information to the gNB-DU via the E2 interface, or can send the seventh indication information to the gNB-CU via the E2 interface, and the gNB-CU can send the seventh indication information to the gNB-DU via the F1 interface.

[0252] S1502: The gNB-CU or gNB-DU sends second indication information to the first terminal. Correspondingly, the first terminal receives the second indication information from the gNB-CU or gNB-DU.

[0253] S1503. The RIC sends the eighth indication information to the gNB-CU or gNB-DU through the E2 interface and / or the F1 interface. Correspondingly, the gNB-CU or gNB-DU receives the eighth indication information from the RIC.

[0254] Among them, the eighth indication information is used to instruct the gNB-CU or gNB-DU to send paging information of the first terminal on a specific PO.

[0255] S1504. The gNB-CU or gNB-DU sends paging information of the first terminal on a specific PO. Accordingly, the first terminal listens to the paging information on the specific PO.

[0256] S1505. The RIC determines that the paging fails.

[0257] S1506. The RIC sends the ninth indication information to the gNB-CU or gNB-DU through the E2 interface and / or the F1 interface. Correspondingly, the gNB-CU or gNB-DU receives the ninth indication information from the RIC through the E2 interface and / or the F1 interface.

[0258] The ninth indication information is used to instruct the gNB-CU or gNB-DU to send the first indication information to the first terminal on the first time domain resources.

[0259] S1507: The gNB-CU or gNB-DU sends first indication information to the first terminal on the first time domain resources. Correspondingly, the first terminal listens for the first indication information on the first time domain resources.

[0260] S1508. The RIC sends the tenth indication information to the gNB-CU or gNB-DU via the E2 interface and / or the F1 interface. Correspondingly, the gNB-CU or gNB-DU receives the tenth indication information from the RIC via the E2 interface and / or the F1 interface.

[0261] The tenth indication information is used to instruct the gNB-CU or gNB-DU to send paging information of the first terminal on the third time domain resources.

[0262] S1509: The gNB-CU or gNB-DU sends paging information of the first terminal on the third time domain resources. Accordingly, the first terminal listens to the paging information on the third time domain resources.

[0263] It can be understood that other descriptions about the information monitoring method shown in Figure 15 can be understood by referring to the descriptions involved in Figures 9 to 14 above, and will not be repeated here.
