Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, in particular to a periodic updating method and device, equipment, storage medium and program product. BACKGROUND

[0002] In the existing NB-IoT (Narrow Band Internet of Things) network, the power consumption of the terminal (i.e. UE) is reduced by implementing the PSM (Power Saving Mode) mechanism.

[0003] After the terminal is registered into the network, it will be in the Connected state (i.e. working state or connected state), at which time the terminal can transmit or receive data with the network side; if the UE in the Connected state has no data interaction with the network side and exceeds the preset time, the terminal will switch to the Idle state (i.e. idle state), at which time the terminal can transmit and receive data, and enter the Connected state again when receiving the downlink data from the network side; if the terminal in the Idle state has no data interaction with the network side and exceeds the preset time, the terminal will switch to the PSM state and enter the PSM period, at which time the terminal will turn off the transceiver signal machine, although the terminal is still registered in the network, the terminal cannot receive the downlink data from the network side until the terminal ends the PSM period and switches to the Connected state. The PSM mechanism can reduce unnecessary signaling interaction between the terminal and the network side, thereby achieving the purpose of reducing the power consumption of the terminal.

[0004] Although the PSM mechanism is quite mature in the related art, the number of terminals accessing the NB-IoT network is huge, and when the NB-IoT network processes concurrent connections of a large number of terminals, since the PSM period of each terminal can be different, a large number of terminals can simultaneously end the PSM period and enter the Connected state, which causes the network resources to be concentratedly used in some time periods, resulting in network uplink congestion, and reducing the network service quality and efficiency. Therefore, how to update the PSM period of the terminal to improve the network service quality of the NB-IoT network has become a problem to be solved.

[0005] At present, there is no efficient PSM period updating method. SUMMARY

[0024] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0025] It should be noted that the present application may involve the use of user data in the embodiments. In actual applications, user-specific personal data can be used in the schemes described herein within the scope permitted by applicable laws and regulations (for example, user explicit consent, actual notification to the user, etc.) in compliance with the applicable laws and regulations of the country.

[0026] Please refer to Figure 1 , Figure 1 is a flowchart of a periodic updating method provided by an embodiment of the present application. In the present embodiment, the periodic updating method is applied to an NB-IoT network side, which includes an NB-IoT base station, an NB-IoT core network element, and an Internet of Things platform. The NB-IoT core network element is provided with a PSM period storage unit and a PSM period arrangement processing unit. The periodic updating method includes steps S110 to S150, and each step is specifically as follows.

[0027] S110: Obtain the timer parameters of each terminal in the base station.

[0028] The timer parameters include T3324 parameters and T3412 parameters.

[0029] Generally, each terminal accessing the NB-IoT network side is configured with multiple timer parameters for setting the Connected period, the Idle period, and the PSM period of the terminal.

[0030] In the existing NB-IoT network, the timer parameters related to the PSM period include a T3324 parameter and a T3412 parameter.

[0031] The T3324 parameter defines the total duration of the Idle period; and the T3412 parameter defines the total duration of the Idle period and the PSM period. Therefore, the duration of the PSM period is the difference between the total duration of the Idle period and the total duration of the Idle period and the PSM period, i.e., the difference between the T3412 parameter value and the T3324 parameter value.

[0032] To adjust and update the PSM period of the terminal, the timer parameters of each terminal in the base station need to be obtained.

[0033] S120: Based on each timer parameter, determine the terminal activation quantity curve.

[0034] Specifically, for each terminal accessing the NB-IoT network side, the PSM period scheduling processing unit of the NB-IoT core network element can predict the number of activated terminals in each NB-IoT base station in a future preset time period by analyzing the two timer parameters of the terminal, i.e., the T3324 parameter and the T3412 parameter, to form a terminal activation quantity curve.

[0035] Optionally, the number of NB-IoT base stations can be multiple; for each NB-IoT base station, there is a corresponding terminal activation quantity curve.

[0036] Please refer to Figure 2 , Figure 2 is a schematic diagram of the terminal activation quantity curve provided by the embodiment of the present application.

[0037] For each base station, the PSM period scheduling processing unit of the NB-IoT core network element can predict the number distribution of activated terminals in the NB-IoT base station in a future preset time period by analyzing the T3324 parameter and the T3412 parameter of each terminal, to form a terminal activation quantity curve.

[0038] Optionally, the future preset time period includes multiple time periods.

[0039] As Figure 2 shown, the future preset time period includes multiple future unit time periods, Figure 2 wherein the unit time is one hour, and the future preset time period can be 24 hours in the future, wherein each hour is one future unit time period, and the future unit time periods are respectively denoted as time 1 to time 24.

[0040] In Figure 2In the graph, the number of activated terminals is presented as a bar chart, with the horizontal axis representing the future unit time period and the vertical axis representing the number of activated terminals in the base station.

[0041] The methods used by the PSM periodic orchestration processing unit to predict data include, but are not limited to, LSTM deep learning algorithms and formulaic methods, where the mathematical formulas in the formulaic method can be manually set by experts.

[0042] Once the terminal activation count curve is generated, it will be sent to the PSM periodic storage unit for storage.

[0043] S130: Based on the terminal activation number curve, determine whether the number of activated terminals in the base station within a future preset time period is greater than or equal to the first preset threshold.

[0044] The activated terminal is the terminal that has ended the PSM cycle. The first preset threshold is determined based on the maximum number of concurrent terminal connections of the base station.

[0045] Specifically, after obtaining the terminal activation number curve, a first preset threshold can be obtained. Based on the terminal activation number curve and the first preset threshold, it is determined whether the number of activated terminals in the base station within a future preset time period is greater than or equal to the first preset threshold, that is, whether the number of activated terminals in the base station within each future unit time period is greater than or equal to the first preset threshold.

[0046] The first preset threshold is determined based on the maximum number of concurrent terminal connections of the base station, and the first preset threshold is the tolerance threshold for the number of active terminals within a unit time period.

[0047] like Figure 2 As shown, the dashed line represents the tolerance threshold for the number of active terminals within a unit of time period.

[0048] S140: If the number of activated terminals in the base station is greater than or equal to the first preset threshold within a future preset time period, then at least one terminal to be adjusted is determined from all terminals.

[0049] Specifically, after setting and obtaining the first preset threshold, if the number of activated terminals in the base station within a future preset time period is greater than or equal to the first preset threshold, the PSM cycle scheduling processing unit can automatically identify and confirm all future unit time periods (i.e., over-limit time periods) that exceed the first preset threshold in terms of the number of activated terminals, and the terminal list corresponding to each future unit time period, based on the terminal activation number curve and the first preset threshold. Each terminal list includes all terminals activated within a future unit time period. At least one terminal to be adjusted is determined from the terminal list to prepare for the adjustment of the next PSM cycle.

[0050] Generally, the number of terminals to be adjusted is the number of terminals that exceeds the first preset threshold.

[0051] For example, the first preset threshold is 10, if the number of activated terminals in a future unit time period is 12, the number of terminals to be adjusted is the number of terminals exceeding the first preset threshold, i.e. 12-10=2, and the number of terminals to be adjusted is 2.

[0052] S150: updating the PSM cycle of the terminal to be adjusted based on the timer parameter of the terminal to be adjusted.

[0053] Specifically, the PSM cycle of the terminal to be adjusted is updated based on the timer parameter of the terminal to be adjusted until the number of activated terminals in the base station in a future preset time period is less than the first preset threshold, avoiding that a large number of terminals end the PSM cycle at the same time period, causing network resources to be concentratedly used in some time periods, resulting in network uplink congestion, and reducing network service quality and efficiency.

[0054] The period updating method provided by the embodiments of the present application obtains the timer parameter of each terminal in the base station; determines the terminal activation quantity curve based on each timer parameter; judges whether the number of activated terminals in the base station in a future preset time period is greater than or equal to the first preset threshold based on the terminal activation quantity curve; the activated terminal is a terminal ending the PSM cycle, and the first preset threshold is determined based on the maximum terminal concurrent connection number of the base station; if the number of activated terminals in the base station in the future preset time period is greater than or equal to the first preset threshold, at least one terminal to be adjusted is determined in all terminals; and the PSM cycle of the terminal to be adjusted is updated based on the timer parameter of the terminal to be adjusted. Through the above manner, the terminal activation quantity curve is determined based on the timer parameter of each terminal in the base station, and then whether the number of activated terminals in the base station in a future preset time period is greater than or equal to the first preset threshold is judged based on the terminal activation quantity curve. If yes, the terminal to be adjusted is determined in all terminals, and the PSM cycle of the terminal to be adjusted is updated based on the timer parameter of the terminal to be adjusted. Since the first preset threshold is determined based on the maximum terminal concurrent connection number of the base station, the network side base station can dynamically adjust the PSM cycle of the terminal according to the network load condition, and the period updating method is scientific and efficient, and can effectively improve the network service quality and efficiency.

[0055] In some embodiments, the timer parameter includes a T3412 parameter.

[0056] The PSM cycle of the terminal to be adjusted is updated based on the timer parameter of the terminal to be adjusted, including: obtaining the T3412 parameter of the terminal to be adjusted, the predicted activation time of the terminal to be adjusted, and the low-load time period of the base station; the predicted activation time is the time when the terminal ends the PSM cycle, and the low-load time period is a future time period in which the number of activated terminals in the base station is less than a second preset threshold; based on the T3412 parameter, the predicted activation time and the low-load time period, the parameter is updated to obtain the T3412 parameter recommendation value of the terminal to be adjusted; and based on the T3412 parameter recommendation value, the PSM cycle of the terminal to be adjusted is updated.

[0057] Specifically, after determining the terminal to be adjusted, for each terminal to be adjusted, the current T3412 parameter Old T3412 of the terminal to be adjusted, the predicted activation time Tj of the terminal to be adjusted, and the low-load time period Td of the base station are obtained.

[0058] Further, for each terminal to be adjusted, based on the T3412 parameter Old T3412, the predicted activation time Tj and the low-load time period Td, the parameter is updated to obtain the T3412 parameter recommendation value New T3412 of the terminal to be adjusted, and the calculation formula of the T3412 parameter recommendation value New T3412 is as follows:

[0059] New T3412 = Old T3412 + Td – Tj;

[0060] Wherein, the T3412 parameter recommendation value New T3412 will be sent to the PSM cycle storage unit for storage.

[0061] Further, for each terminal to be adjusted, based on the T3412 parameter recommendation value, the PSM cycle of the terminal to be adjusted is updated.

[0062] In some embodiments, after updating the PSM cycle of the terminal to be adjusted based on the timer parameter of the terminal to be adjusted, it further includes: updating the terminal activation quantity curve based on the T3412 parameter recommendation value; judging whether the number of activated terminals in the base station in a future preset time period is greater than or equal to a first preset threshold based on the updated terminal activation quantity curve; if the number of activated terminals in the base station in the future preset time period is less than the first preset threshold, stopping updating the PSM cycle of each terminal.

[0063] For each terminal to be adjusted, after updating the PSM cycle of the terminal to be adjusted, the terminal activation quantity curve of the corresponding base station can be updated in real time based on the T3412 parameter recommendation value of the terminal to be adjusted, and the updated terminal activation quantity curve is sent to the PSM cycle storage unit for storage.

[0064] Further, based on the updated terminal activation quantity curve, it is determined whether the number of activated terminals in the base station in a future preset time period is greater than or equal to a first preset threshold.

[0065] If the number of activated terminals in the base station in the future preset time period is less than the first preset threshold, that is, the number of activated terminals in all over-limit time periods is below the tolerance threshold of the number of activated terminals in a unit time period, the PSM period of each terminal is stopped from being updated.

[0066] Preferably, the PSM period update can be performed during a business idle time (for example, early morning every day), and by updating the terminal activation quantity curve and the recommended value of the T3412 parameter of the terminal to be adjusted, it can be ensured that the network side can adapt to the change of network traffic.

[0067] In some embodiments, before obtaining the timer parameter of each terminal in the base station, the method further comprises: setting a PSM period storage unit; wherein the PSM period storage unit is used to store a terminal list, a terminal activation quantity curve, a first preset threshold and a recommended value of a T3412 parameter; and the terminal list is used to record the terminal identifiers of all terminals in the base station that have been pre-configured with the PSM period.

[0068] The PSM period storage unit is arranged at the core network element side, and can store and manage the key information of the terminals that have been configured with the PSM period under each base station in the NB-IoT network.

[0069] Specifically, the PSM period storage unit is used to store the terminal list, the terminal activation quantity curve, the first preset threshold and the recommended value of the T3412 parameter.

[0070] The terminal list is used to record the terminal identifiers of all terminals in each base station that have been pre-configured with the PSM period, so as to facilitate subsequent period update processing.

[0071] The terminal activation quantity curve is calculated by the PSM period scheduling processing unit, and can be used to predict the number trend of activated terminals in the base station in a future preset time period, thereby providing data support for load optimization.

[0072] The first preset threshold is the tolerance threshold of the number of activated terminals in a unit time period, and can be determined based on the maximum number of concurrent terminal connections of the base station (at present, the maximum number of concurrent terminal connections of most base stations is 12). By setting the tolerance threshold of the number of activated terminals in a unit time period, it can be ensured that the network resources are reasonably allocated, and uplink congestion is avoided.

[0073] The recommended value of the T3412 parameter is calculated by the PSM period scheduling processing unit, and is used to guide the sleep-wake period adjustment of the terminal.

[0074] In some embodiments, the method further comprises: receiving a registration request of a terminal to be registered; determining a timer parameter of the terminal to be registered based on the registration request; the timer parameter comprises a T3412 parameter and a T3324 parameter; determining whether the T3412 parameter recommended value of the terminal to be registered is stored in the PSM cycle storage unit; if the T3412 parameter recommended value of the terminal to be registered is not stored in the PSM cycle storage unit, updating the terminal activation quantity curve based on the timer parameter of the terminal to be registered; determining whether the number of activated terminals in the base station in a future preset time period is greater than or equal to a first preset threshold based on the updated terminal activation quantity curve; if the number of activated terminals in the base station in the future preset time period is greater than or equal to the first preset threshold, updating the T3412 parameter of the terminal to be registered based on the timer parameter of the terminal to be registered, and obtaining the T3412 parameter recommended value of the terminal to be registered; and updating the PSM cycle of the terminal to be registered based on the T3412 parameter recommended value of the terminal to be registered.

[0075] Please refer to Figure 3 , Figure 3 is a flowchart of a cycle updating method of a new terminal provided by the embodiments of the present application.

[0076] It can be understood that the NB-IoT network side may continuously accept new terminals to access, and when a new terminal (terminal to be registered) needs to access the NB-IoT network side, a registration request needs to be sent to the NB-IoT network side.

[0077] As shown in Figure 3 , the NB-IoT core network element of the NB-IoT network side first sends an RRC SETUP message to the terminal to be registered; the RRC SETUP message is a message in the Radio Resource Control (RRC) protocol, which is a response of the network side to the RRC request initiated by the terminal, and the message aims to provide detailed configurations required for communication between the terminal and the network side.

[0078] Further, the terminal to be registered sends an Attach Request message to the network side in response to the RRC SETUP message; the Attach Request message is a kind of registration request message, and when the terminal accesses the NB-IoT network for the first time, the Attach Request message needs to be sent to the network side to start the Attach process (i.e. the attachment process), and complete the registration and authentication of the terminal in the network side.

[0079] Among them, the Attach Request message can carry the timer parameter of the terminal to be registered, and the timer parameter comprises a T3412 parameter and a T3324 parameter.

[0080] Further, the network side can receive a registration request of the terminal to be registered, i.e. an Attach Request message, and determine the T3412 parameter and the T3324 parameter of the terminal to be registered based on the registration request.

[0081] Further, after receiving the registration request of the terminal to be registered, the network side needs to perform security authentication with the terminal to be registered through a security authentication message, i.e. an Authentication / Security message, to ensure communication security.

[0082] Further, after completing the security authentication, the NB-IoT core network element first determines whether the T3412 parameter recommended value of the terminal to be registered is stored in the PSM cycle storage unit.

[0083] If the T3412 parameter recommended value New T3412 of the terminal to be registered is stored in the PSM cycle storage unit, the T3412 parameter recommended value New T3412 and the T3324 parameter of the terminal to be registered can be returned to the terminal to be registered.

[0084] If the T3412 parameter recommended value of the terminal to be registered is not stored in the PSM cycle storage unit, the update of the PSM cycle needs to be performed, and the terminal activation quantity curve is updated in real time based on the timer parameter of the terminal to be registered.

[0085] Further, based on the updated terminal activation quantity curve, it is determined whether the number of activated terminals in the base station in a future preset time period is greater than or equal to a first preset threshold.

[0086] If the number of activated terminals in the base station in the future preset time period is greater than or equal to the first preset threshold, the T3412 parameter of the terminal to be registered is updated based on the timer parameter of the terminal to be registered, and the T3412 parameter recommended value of the terminal to be registered is obtained.

[0087] Further, based on the T3412 parameter recommended value of the terminal to be registered, the PSM cycle of the terminal to be registered is updated, and the T3412 parameter recommended value of the terminal to be registered is returned to the terminal to be registered through an Attach Accept message; at the same time, the related data of the PSM cycle storage unit is updated synchronously to ensure the consistency of the data.

[0088] Further, the network side sends an RRC Release message to the terminal to be registered to complete the entire registration process.

[0089] In some embodiments, the method further comprises: receiving a registration request of the terminal to be registered; determining the timer parameters of the terminal to be registered based on the registration request; the timer parameters comprise the T3412 parameter and the T3324 parameter; determining whether the T3412 parameter recommended value of the terminal to be registered is stored in the PSM cycle storage unit; if the T3412 parameter recommended value of the terminal to be registered is not stored in the PSM cycle storage unit, updating the terminal activation quantity curve based on the timer parameters of the terminal to be registered; determining whether the number of activated terminals in the base station in a future preset time period is greater than or equal to a first preset threshold based on the updated terminal activation quantity curve; and if the number of activated terminals in the base station in the future preset time period is less than the first preset threshold, not updating the PSM cycle of the terminal to be registered.

[0090] Specifically, the network side can receive a registration request of the terminal to be registered, i.e., an Attach Request message, and determine the T3412 parameter and the T3324 parameter of the terminal to be registered based on the registration request.

[0091] Further, after receiving the registration request of the terminal to be registered, the network side needs to perform security authentication with the terminal to be registered through a security authentication message, i.e., an Authentication / Security message, to ensure communication security.

[0092] Further, after completing the security authentication, the NB-IoT core network element first determines whether the T3412 parameter recommended value of the terminal to be registered is stored in the PSM cycle storage unit.

[0093] If the T3412 parameter recommended value of the terminal to be registered is not stored in the PSM cycle storage unit, the terminal activation quantity curve is updated based on the timer parameters of the terminal to be registered.

[0094] Further, based on the updated terminal activation quantity curve, it is determined whether the number of activated terminals in the base station in a future preset time period is greater than or equal to a first preset threshold.
