[0002] In the field of communication technologies, messages are transmitted using channels as the medium, and terminal devices obtain messages from channels to achieve communication. However, when encountering adverse channel conditions, such as when a terminal device is placed in a backpack, pocket, or in an environment such as an elevator, it may cause the terminal device to miss messages, affecting the effectiveness of communication.

Currently, some examples of terminal devices include: mobile phones, tablet computers, laptop computers, handheld computers, mobile internet devices (abbreviated as MID), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical surgery, wireless terminals in smart grid, wireless terminals in transportation safety, wireless terminals in smart city, wireless terminals in smart home, cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDA), handheld devices with wireless communication capabilities, computing devices, or other processing devices connected to a wireless modem, vehicle-mounted devices, wearable devices, terminal devices in a 5G network, or terminal devices in a future evolved public land mobile network (PLMN), etc. This application is not limited thereto.

[0158] By way of example and not limitation, in the present application, the terminal device may be a terminal device in an Internet of Things (IoT) system. The Internet of Things is an important part of the future development of information technology. Its main technical feature is to connect objects to the network through communication technology, so as to realize an intelligent network of human-machine interconnection and object-object interconnection. Exemplarily, the terminal device in the embodiments of the present application may be a wearable device. A wearable device, also known as a wearable intelligent device, is a general term for devices developed by applying wearable technology to the intelligent design of daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that can be directly worn on the body or integrated into the user's clothes or accessories. A wearable device is not only a hardware device, but can also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable intelligent devices include those with complete functions and large sizes that can achieve complete or partial functions without relying on a smart phone, such as smart watches or smart glasses, etc., and those that only focus on a certain type of application function and need to cooperate with other devices such as smart phones, such as various smart bracelets and smart jewelry for physical sign monitoring.

[0159] By way of example and not limitation, in the embodiments of the present application, the terminal device may also be a terminal device in machine type communication (MTC). In addition, the terminal device may also be an in-vehicle module, in-vehicle module group, in-vehicle component, in-vehicle chip, or in-vehicle unit built into a vehicle as one or more components or units. The vehicle can implement the method provided in the present application through the built-in in-vehicle module, in-vehicle module group, in-vehicle component, in-vehicle chip, or in-vehicle unit. Therefore, the embodiments of the present application can also be applied to vehicle networking, such as vehicle-to-everything (V2X), long term evolution-vehicle (LTE-V), vehicle-to-vehicle (V2V) technology, etc.

[0160] Exemplarily, the elastic notification signal transmitted on the elastic notification channel is used to prompt the terminal device of missed messages.

[0161] As shown in the scenario example, communication signals such as calls and text messages of the terminal device are transmitted through the paging channel. When the channel condition of the paging channel is poor, the conventional paging method may not be able to reliably deliver the prompt message to the terminal, and the terminal device may miss the message, such as incoming calls, text messages, etc. The elastic notification channel is an independent channel, and the elastic notification signal is transmitted on the elastic notification channel. The elastic notification signal has different frequencies to ensure that the elastic notification signal has stronger transmission ability compared to the conventional paging signal, thereby effectively improving the messages missed by the terminal device.

[0162] Optionally, the elastic notification signal enhances the transmission ability by means of amplitude gain, waveform change, or coding scheme change.

[0163] However, the elastic notification channel is a non-resident channel. To save energy consumption, the terminal device cannot frequently monitor the elastic notification channel, and there may be a problem of missing the elastic notification signal in the elastic notification channel, resulting in the problem of the terminal device missing the message, and further resulting in the problem of low communication reliability.

[0164] It should be noted that the channel monitoring method, device, electronic device, storage medium, and program product of the present application can be used in the field of communication technology, and can also be used in any field other than the communication technology. The application field of the channel monitoring method, device, electronic device, storage medium, and program product of the present application is not limited.

[0165] The channel monitoring method provided by the present application aims to solve the above technical problems in the prior art.

[0166] The following uses specific embodiments to describe in detail the technical solution of the present application and how the technical solution of the present application solves the above technical problems. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the drawings.

[0167] Figure 2 It is a schematic flowchart of a channel monitoring method provided by an embodiment of the present application. The method includes the following steps:

[0168] S201. Receive configuration parameters, where the configuration parameters are used for the terminal device to determine the monitoring opportunity of the elastic notification channel, and the monitoring opportunity of the elastic notification channel is the target frame for monitoring the elastic notification channel.

[0169] Exemplarily, the monitoring opportunity corresponds to the sending opportunity of the elastic notification signal.

[0170] Exemplarily, the configuration parameters are determined by the network device, that is, the access network device and / or the core network device according to the sending opportunity of the elastic notification signal, and sent to the terminal device.

[0171] Combined with a scenario example, the network device generates configuration parameters according to the transmission timing of the elastic notification signal and sends the configuration parameters to the terminal device, so that the terminal device determines the listening timing according to the configuration parameters. The listening timing corresponds to the transmission timing, that is, during the listening timing, there is a transmission of the elastic notification signal on the elastic notification channel, so that when the terminal device listens to the elastic notification channel, it can accurately listen to the elastic notification signal.

[0172] Exemplarily, the access network device sends an elastic notification signal on the target frame, and the target frame is also the wireless frame used by the terminal device for listening. The terminal device starts the listening function on the target frame to listen to the elastic notification channel to accurately obtain each elastic notification signal. The terminal device turns off the listening function on non-target frames to save the energy consumption of the terminal device.

[0173] As an example, the access network device sends an elastic notification signal on the target frame according to a preset condition, for example, the terminal device's paging fails, or the access network device sends an elastic notification signal according to an indication from the core network. When the preset condition is met, it is necessary to prompt the terminal device of the missed message through the elastic notification signal. When the preset condition is not met, the terminal device can receive the message normally, and at this time, the access network device does not send an elastic notification signal, which can reduce the energy consumption.

[0174] Exemplarily, the target frame can be one or more, and there can be a periodicity between multiple target frames.

[0175] In this feasible implementation manner, by determining the target frame, the terminal device can clarify the listening period, thereby improving the accuracy of listening to the elastic notification channel.

[0176] S202. Listen to the elastic notification channel according to the listening timing.

[0177] Optionally, the listening timing has a periodicity. Listen to the elastic notification channel according to the period corresponding to the listening timing. Thus, receiving the configuration parameters once can achieve multiple listenings, reduce the number of times the network device sends the configuration parameters, and further reduce the communication overhead.

[0178] Optionally, the period corresponding to the listening timing corresponds to the period corresponding to the transmission timing, ensuring that the listening timing of each period covers the transmission timing to avoid missing the elastic notification signal.

[0179] Combined with a scenario example, if the period corresponding to the transmission timing is period A, the configuration parameters are determined according to period A, and the period determined by the terminal device according to the configuration parameters is also period A. When the network device sends the elastic notification signal according to period A, the terminal device can listen to the elastic notification channel according to period A, so that when the network device sends the elastic notification signal, the terminal device can receive the elastic notification signal, thereby avoiding missing the elastic notification signal.

[0180] Optionally, the terminal device may monitor the flexible notification channel when the channel quality or other preset conditions are met.

[0181] Illustrated with a scenario example, for instance, when the channel quality is poor, the terminal device monitors the flexible notification channel according to the monitoring opportunity. When the channel quality is poor, the terminal device is more likely to miss messages. At this time, monitoring the flexible notification channel can effectively determine the missed messages. When the channel quality is good, the terminal device is less likely to miss messages. Therefore, there is no need to monitor the flexible notification channel, which can save the energy consumption of the terminal device.

[0182] Optionally, the schemes of periodically monitoring the flexible notification channel and monitoring the flexible notification channel according to the channel quality can be executed simultaneously.

[0183] Exemplarily, determine the period for monitoring the flexible notification channel according to the configuration parameter, detect the channel quality in each period. If the channel quality is good, it indicates that the terminal device can communicate normally, and the current period is skipped. If the channel quality is poor, it indicates that the terminal device cannot communicate normally, and the flexible notification channel is monitored in the current period to obtain the missed messages of the terminal device.

[0184] The channel monitoring method provided in the embodiments of this application receives a configuration parameter, which is used for the terminal device to determine the monitoring opportunity of the flexible notification channel. The monitoring opportunity of the flexible notification channel is the target frame for monitoring the flexible notification channel; monitor the flexible notification channel according to the monitoring opportunity. In the above scheme, the monitoring opportunity is the time period when there is a flexible notification signal in the flexible notification channel. By receiving the configuration parameter, the terminal device can accurately determine the monitoring opportunity. The terminal device monitoring the flexible notification channel according to the monitoring opportunity can effectively avoid missing the flexible notification signal, thereby improving the reliability of communication.

[0185] A feasible implementation manner is that the configuration parameter includes at least one of the following at least one item: flexible notification period, or flexible notification identifier.

[0186] Next, Figure 3 The grouped monitoring of the flexible notification channel is described.

[0187] Figure 3 This is a schematic diagram of the grouped monitoring of the flexible notification channel provided in the embodiments of this application. As Figure 3 shown, the network device sends a configuration parameter to the terminal device. The terminal device determines the monitoring opportunity according to the configuration parameter, and the terminal device monitors the flexible notification channel in groups according to the monitoring opportunity. Among them, in the scheme of grouped monitoring of the flexible notification channel, the configuration parameter includes at least one of the following at least one item: flexible notification period, or flexible notification identifier.

[0188] Exemplarily, the flexible period is the period for the network device to send the flexible notification signal. The flexible notification identifier is an identifier assigned by the network device to the terminal device.

[0189] Exemplarily, multiple terminal devices are grouped by an elastic notification period and an elastic notification identifier. Each terminal device corresponds to a target frame, and each terminal device listens to an elastic notification channel according to the corresponding target frame, so as to stagger the target frames of multiple terminal devices, thereby reducing the congestion of the elastic notification channel.

[0190] Optionally, the access network device sends the elastic notification period to the terminal device.

[0191] In this feasible implementation, the terminal devices are grouped, and the target frames of multiple terminal devices are staggered according to the grouping, so as to reduce the congestion of the elastic notification channel, thereby improving the communication reliability of the terminal devices.

[0192] A feasible implementation, the target frame is the first frame; the first frame satisfies the following formula:

[0193]

[0194] where SFN1 is the first frame, P is the elastic notification period, and RID is the elastic notification identifier.

[0195] Exemplarily, the result of taking the modulus of the elastic notification identifier by the elastic notification period is the same as the result of taking the modulus of the first frame by the elastic notification period.

[0196] Combined with the scenario example, through the modulo operation, different elastic notification identifiers are grouped. Among them, the elastic notification identifiers that differ by an integer multiple of the elastic notification period are divided into a group, and each group corresponds to a first frame. For example, the multiple elastic notification identifiers corresponding to multiple terminal devices are 10, 11, 12, 13, 14, and 15 respectively, and the elastic notification period is 5. The results of taking the modulus operation are 0, 1, 2, 3, 4, and 0 respectively. Through the formula corresponding to the first frame, it can be calculated that the terminal devices with elastic notification identifiers 10 and 15 are in a group corresponding to a first frame, and the terminal devices with elastic notification identifiers 11, 12, 13, and 14 respectively correspond to different first frames, thereby realizing the grouping process of multiple terminal devices.

[0197] Combined with the scenario example, if multiple elastic notification signals occur simultaneously, through the modulo assignment of the elastic notification identifier, the multiple elastic notification signals will be sent in different radio frames in sequence, reducing the probability of signal interference.

[0198] In this feasible implementation, by grouping the terminal devices, the first frames of multiple terminal devices can be staggered, making the first frames of multiple terminal devices more dispersed, thereby reducing the congestion of the elastic notification channel and improving the communication reliability.

[0199] In a feasible implementation manner, the configuration parameter further includes RF_offset, where RF_offset is the radio frame offset; the first frame satisfies the following formula:

[0200]

[0201] Exemplarily, based on the formula of the first frame above, the radio frame offset is introduced, and the first frame is dynamically offset by the radio frame offset. The position of the first frame can be flexibly adjusted by the radio frame offset, further avoiding signal interference that may be caused by modulo operation.

[0202] Combined with a scenario example for illustration, in a scenario of dense deployment, for example, when multiple network devices are densely deployed, or when co-channel interference occurs due to radio frame synchronization in adjacent cells or devices, the first frame can be staggered by dynamically adjusting the radio frame offset, thereby avoiding signal interference.

[0203] Optionally, the radio frame offset is sent to the terminal device through system information or Radio Resource Control (RRC) signaling.

[0204] In this feasible implementation manner, the first frames of different terminal devices can be dynamically staggered by the radio frame offset, thereby further reducing the congestion of the flexible notification channel and improving the reliability of communication.

[0205] A feasible implementation manner, the configuration parameter further includes a flexible notification offset, and the target frame is the second frame; the second frame satisfies the following formula:

[0206]

[0207] Wherein, SFN2 is the second frame, P is the flexible notification period, RID is the flexible notification identifier, and K is the flexible notification offset.

[0208] Optionally, the flexible notification offset is sent from the access network device to the terminal device.

[0209] Exemplarily, through perform the first-layer grouping, and then through perform the second-layer grouping to obtain a more dispersed second frame.

[0210] In this feasible implementation manner, through multi-layer grouping, the second frame can be made more dispersed, which can further reduce the congestion of the flexible notification channel and improve the reliability of communication.

[0211] A feasible implementation manner, the configuration parameter further includes RF_offset, where RF_offset is the radio frame offset; the second frame satisfies the following formula:

[0212] .

[0213] Exemplarily, based on the formula of the above second frame, a wireless frame offset is introduced, and the second frame is dynamically offset by the wireless frame offset. The position of the second frame can be flexibly adjusted by the wireless frame offset, further avoiding signal interference that may be caused by modulo operation.

[0214] In this feasible implementation, the second frames of different devices can be dynamically staggered by the wireless frame offset, thereby further reducing the congestion of the flexible notification channel and improving the reliability of communication.

[0215] A feasible implementation, the configuration parameter further includes the number of wireless frames in each flexible notification period, and the target frame is the third frame; the third frame satisfies the following formula:

[0216]

[0217] Wherein, SFN3 is the third frame, P is the flexible notification period, N is the number of wireless frames in each flexible notification period, and RID is the flexible notification identifier.

[0218] Next, Figure 4 the periodic listening of the flexible notification channel will be described.

[0219] Figure 4 The figure is a schematic diagram of the periodic listening of the flexible notification channel provided by the embodiment of the present application. As Figure 4 shown, the network device sends configuration parameters to the terminal device, the terminal device determines the listening opportunity according to the configuration parameters, and the terminal device periodically listens to the flexible notification channel according to the listening opportunity.

[0220] Optionally, the access network device sends the number of wireless frames in each flexible notification period to the terminal device.

[0221] Exemplarily, by grouping the terminal devices, the number of groups is the same as the number of wireless frames in the flexible notification period, and by determining the interval between wireless frames, the position of the third frame corresponding to the terminal device is accurately determined through grouping and interval.

[0222] Combined with a scenario example for illustration, for example, N is 2, indicating that there are 2 wireless frames in a flexible notification period. By calculation, multiple flexible notification identifiers can be evenly distributed in 2 wireless frames. For example, RID is 22 and 23. By the calculation results are 0 and 1 respectively, then the terminal device with RID 22 is assigned to the first wireless frame in the flexible notification period, and the terminal device with RID 23 is assigned to the second wireless frame in the flexible notification period. For example, P is 32, The result is 16, indicating that the interval between adjacent radio frames within one period is 16. By calculation, it can be obtained that the position of the first radio frame in the flexible notification period is 16, and the position of the second radio frame in the flexible notification period is 32. By determining the positions of each terminal device in the flexible notification period, multiple third frames corresponding to multiple terminal devices can be determined.

[0223] In this feasible implementation manner, multiple third frames of multiple terminal devices are evenly distributed in N frames within the flexible notification period, and N radio frames of flexible notifications are evenly distributed within the flexible notification period, which can reduce the congestion of the flexible notification channel and improve the reliability of communication.

[0224] A feasible implementation manner, the configuration parameter further includes RF_offset, and RF_offset is the radio frame offset; the third frame satisfies the following formula:

[0225] .

[0226] Exemplarily, based on the formula of the above third frame, a radio frame offset is introduced, and the third frame is dynamically offset by the radio frame offset. The position of the third frame can be flexibly adjusted by the radio frame offset, further avoiding signal interference that may be caused by modulo operation.

[0227] In this feasible implementation manner, the third frames of different devices can be dynamically staggered by the radio frame offset, thereby further reducing the congestion of the flexible notification channel and improving the reliability of communication.

[0228] A feasible implementation manner, the target frame is a paging frame, and the configuration parameter includes at least one of the following: discontinuous reception period, the number of paging frames in each discontinuous reception period, terminal device identifier, or offset of the paging frame; listening to the flexible notification channel includes: listening to the flexible notification channel in the paging frames of each paging period; alternately listening to the flexible notification channel and the paging channel in the paging frames of adjacent paging periods; or, listening to the flexible notification channel in the adjacent frames of the paging frames of each paging period.

[0229] Exemplarily, the paging frame is a specific radio frame within the System Frame Number (SFN) period, and is used to determine the time window for a terminal device in the RRC idle state or RRC inactive state to wake up and listen for paging messages.

[0230] Exemplarily, listening to the flexible notification channel in the paging frames of each paging period, that is, when the channel quality or other preset conditions are met, changing to listen to the flexible notification channel in the paging frame.

[0231] Combined with scenario examples, when the channel quality or other preset conditions are met, the communication quality is poor, and even if the paging channel is monitored, messages will be missed. Switching to monitoring the flexible notification channel can effectively obtain the missed messages.

[0232] Exemplarily, in adjacent paging cycles, the flexible notification channel and the paging channel are alternately monitored in the paging frames, that is, the flexible notification channel and the paging channel are alternately monitored. If the flexible notification channel is monitored in the previous cycle, the paging channel is monitored in the current cycle. If the paging channel is monitored in the previous cycle, the flexible notification channel is monitored in the current cycle.

[0233] Next, Figure 5 an explanation of the alternate monitoring of the flexible notification channel will be given.

[0234] Figure 5 is a schematic diagram of the alternate monitoring of the flexible notification channel provided by the embodiment of the present application. As Figure 5 shown, the flexible notification channel and the paging channel are alternately monitored according to the paging cycle of the paging frame, and different channels are monitored in adjacent paging frames.

[0235] Combined with scenario examples, when multiplexing paging frames, alternately monitoring the flexible notification channel and the paging channel can effectively isolate the receiving time periods of the flexible notification channel and the paging channel, thereby avoiding signal interference.

[0236] Exemplarily, the flexible notification channel is monitored in adjacent frames of the paging frames in each paging cycle, where the adjacent frames can be the previous frame or the next frame of the paging frame.

[0237] Next, Figure 6 an explanation of monitoring the flexible notification channel in adjacent frames will be given.

[0238] Figure 6 is a schematic diagram of monitoring the flexible notification channel in adjacent frames provided by the embodiment of the present application. As Figure 6 shown, the paging channel is monitored in each paging frame, and the flexible notification channel is monitored in one of the adjacent frames of each paging frame.

[0239] Combined with scenario examples, when multiplexing paging frames, by monitoring the flexible notification channel in adjacent frames of the paging frame, the receiving time periods of the flexible notification channel and the paging channel can be effectively isolated, thereby avoiding signal interference.

[0240] In this feasible implementation, the paging frame is a wireless frame necessary for the communication of the terminal device. By multiplexing the paging frame to determine the timing of monitoring the flexible notification channel, the existing standards can be relied on to reduce the deployment cost.

[0241] A feasible implementation, the paging frame satisfies the following formula:

[0242]

[0243] Wherein, SFN4 is a paging frame, T is a discontinuous reception period, M is the number of paging frames in each discontinuous reception period, UE_ID is the identifier of the terminal device, and PF_offset is the offset of the paging frame.

[0244] Exemplarily, the discontinuous reception period is the time interval for the terminal device to wake up and monitor the paging channel. The offset of the paging frame is used to dynamically adjust the position of the paging frame.

[0245] Exemplarily, by grouping the terminal devices, the number of groups is the same as the number of paging frames in the discontinuous period, and by distributing multiple terminal devices evenly among multiple paging frames in the discontinuous reception period. By determining the interval between paging frames. The position of the paging frame corresponding to the terminal device is accurately determined through grouping and the interval.

[0246] Exemplarily, the paging frames corresponding to different terminal devices can be dynamically staggered through the offset of the paging frame.

[0247] In this feasible implementation, through grouping and adjustment of the offset of the paging frame, the multiple paging frames corresponding to multiple terminal devices can be made more dispersed, thereby reducing the congestion of the flexible notification channel and improving the reliability of communication.

[0248] A feasible implementation, the configuration parameters further include: flexible notification time slot offset and / or flexible notification symbol offset; monitoring the flexible notification channel includes: monitoring the flexible notification channel in a target time slot, where the target time slot is calculated from a target frame according to the flexible notification time slot offset; or, monitoring the flexible notification channel in a target symbol, where the target symbol is calculated from a target frame or a target time slot according to the flexible notification symbol offset.

[0249] Exemplarily, the access network device sends the flexible notification time slot offset and / or the flexible notification symbol offset to the terminal device.

[0250] Exemplarily, the flexible notification time slot offset is used to indicate the number of time slots of the target time slot, and the flexible notification symbol offset is used to indicate the symbol position of the target symbol.

[0251] Exemplarily, after determining the target frame, the monitoring opportunity is further located to a time slot or a symbol through the flexible notification time slot offset and / or the flexible notification symbol offset.

[0252] Exemplarily, after determining the target frame, first determine the number of time slots of the target time slot through the time slot offset, and then, based on the target time slot, determine the symbol position of the target symbol through the symbol offset.

[0253] Illustrated with a scenario example, for instance, if the elastic notification time slot offset is 7, the target time slot is the 7th time slot of the target frame. For example, if the elastic notification symbol offset is 13, the target symbol is the 13th symbol of the target time slot.

[0254] In this feasible implementation, by positioning the listening opportunity at the time slot level or symbol level, the listening opportunities of different terminal devices can be effectively isolated, thereby reducing the congestion of the elastic notification channel and enhancing the reliability of communication. Moreover, by positioning the listening opportunity at the time slot level or symbol level, the duration for the terminal device to listen to the elastic notification channel can be effectively shortened, thus reducing the power consumption of the terminal device.

[0255] A feasible implementation, the elastic notification identifier is one of the following: Temporary Mobile Subscriber Identity; Hash value of the Temporary Mobile Subscriber Identity; Cell Radio Network Temporary Identifier; or, a dedicated elastic notification identifier for the terminal device.

[0256] Exemplarily, the Temporary Mobile Subscriber Identity can be 5G-S-TMSI, and the hash value of the Temporary Mobile Subscriber Identity can be 5G-S-TMSI mod 1024.

[0257] Exemplarily, the core network device or the access network device sends the elastic notification identifier to the terminal device.

[0258] Optionally, the core network device sends the Temporary Mobile Subscriber Identity to the terminal device and the access network device.

[0259] Optionally, the terminal device receives the dedicated elastic notification identifier for the terminal device through Non-Access Stratum (NAS) signaling, or the terminal device receives the dedicated elastic notification identifier for the terminal device through RRC signaling.

[0260] In this feasible implementation, with multiple types of elastic notification identifiers, the listening opportunity of the terminal device can be determined in multiple ways, thereby adapting to different application scenarios and enhancing the comprehensiveness of channel listening.

[0261] A feasible implementation, the channel listening method further includes: sending the capability information of the terminal device to the access network device, and the capability information is used to indicate that the terminal device has the capability to listen to the elastic notification channel.

[0262] Optionally, the capability information includes but is not limited to: supported frequency bands, carrier aggregation capability, Multiple-Input Multiple-Output (MIMO) configuration, or information such as supported radio access technologies (e.g., supporting NR, LTE, etc.).

[0263] Optionally, the terminal device actively reports the capability information of the terminal device to the access network device during the initial access and handover processes.

[0264] Optionally, the terminal device receives an indication from the network device and reports the capability information of the terminal device to the access network device according to the indication.

[0265] Combined with a scenario example, it is illustrated that by indicating through the capability information that the terminal device has the ability to monitor the flexible notification channel, on this basis, the core network allocates a dedicated flexible notification identifier for the terminal device, which can ensure the normal use of the dedicated flexible notification identifier of the terminal device on the terminal device.

[0266] In this feasible implementation manner, it can be clearly indicated through the capability information whether the terminal device has the ability to monitor the flexible notification channel, enabling the network device to accurately allocate the dedicated flexible notification identifier for the terminal device according to the capability information, thereby improving the reliability of communication.

[0267] A feasible implementation manner is that the dedicated flexible notification identifier of the terminal device is a dedicated flexible notification identifier allocated by the core network device for the terminal device; or, the dedicated flexible notification identifier of the terminal device is a dedicated flexible notification identifier allocated by the access network device for the terminal device.

[0268] Next, Figure 7 the allocation of the dedicated flexible notification identifier for the terminal device will be described.

[0269] Figure 7 FIG. is a schematic diagram of the allocation of the dedicated flexible notification identifier provided by the embodiment of the present application. As Figure 7 shown, the terminal device sends capability information to the network device, the network device allocates a dedicated flexible notification identifier for the terminal device according to the capability information, and the network device sends the dedicated flexible notification identifier of the terminal device to the terminal device. Among them, the network device can be an access network device or a core network device.

[0270] Exemplarily, the capability information includes the flexible notification capability of the terminal device.

[0271] As an example, the core network device allocates a dedicated flexible notification identifier for the terminal device according to the subscription information of the terminal device. Among them, the subscription information includes the flexible notification parameters of the terminal device.

[0272] Exemplarily, the flexible notification parameters include at least one of the following: whether the terminal device uses flexible notification, the service type of the terminal device using flexible notification, or the list of allowed callers using flexible notification.

[0273] Illustrated with a scenario example, for instance, the service types for which the terminal device uses elastic notifications can include: voice services, data services, or SMS services, etc. In the calling party's allowed list, for example, if the list contains the number 1XXXXXXXXXX, then when the calling party's number is the above number, an elastic notification signal is sent; when the calling party's number is other numbers, no elastic notification signal is sent. Another example is that if the list contains 10.10.10.*, then when the calling party's IP address is a website in the above network segment, an elastic notification signal is sent; when the calling party's address is other websites, no elastic notification signal is sent.

[0274] In this feasible implementation manner, through various allocation methods of dedicated elastic notification identifiers for terminal devices, different application scenarios can be adapted, thereby enhancing the comprehensiveness of channel monitoring.

[0275] Figure 8 This is a schematic structural diagram of a channel monitoring device provided by an embodiment of the present application. As Figure 8 shown, the channel monitoring device 80 may include: a first receiving module 81, a first monitoring module 82, a first execution module 83, and a first sending module 84, where

[0276] The first receiving module 81 is configured to receive configuration parameters, where the configuration parameters are used for the terminal device to determine the monitoring timing of the elastic notification channel, and the monitoring timing of the elastic notification channel is the target frame for monitoring the elastic notification channel;

[0277] The first monitoring module 82 is configured to monitor the elastic notification channel according to the monitoring timing.

[0278] It should be noted that the channel monitoring device shown in the embodiment of the present application can execute the technical solutions shown in the above method embodiments, and its implementation principle and beneficial effects are similar, which will not be elaborated here.

[0279] In a possible implementation manner, the configuration parameters at least include at least one of the following: elastic notification period, or elastic notification identifier.

[0280] In a possible implementation manner, the target frame is the first frame; the first frame satisfies the following formula:

[0281]

[0282] where SFN1 is the first frame, P is the elastic notification period, and RID is the elastic notification identifier.

[0283] In a possible implementation manner, the configuration parameter further includes RF_offset, and RF_offset is the radio frame offset; the first frame satisfies the following formula:

[0284] .

[0285] In a possible implementation, the configuration parameter further includes an elastic notification offset, and the target frame is the second frame; the second frame satisfies the following formula:

[0286]

[0287] where SFN2 is the second frame, P is the elastic notification period, RID is the elastic notification identifier, and K is the elastic notification offset.

[0288] In a possible implementation, the configuration parameter further includes RF_offset, and RF_offset is the radio frame offset; the second frame satisfies the following formula:

[0289] 。

[0290] In a possible implementation, the configuration parameter further includes the number of radio frames in each elastic notification period, and the target frame is the third frame; the third frame satisfies the following formula:

[0291]

[0292] where SFN3 is the third frame, P is the elastic notification period, N is the number of radio frames in each elastic notification period, and RID is the elastic notification identifier.
