In the technical scheme provided by the embodiment of the invention, aiming at the terminal with the residual electric quantity being greater than the set threshold value, the base station determines the times of dispatching the terminal by the base station through the energy efficiency of the terminal, and dispatches the terminal based on the times of dispatching the terminal by the base station, wherein the lower the energy efficiency of the terminal is, the fewer the times of dispatching the terminal by the base station are, the residual electric quantity of the terminal is saved, and the endurance time of the terminal is prolonged.
The base station related to the embodiment of the invention can comprise a plurality of cells. A base station may also be referred to as an access point, or a terminal in an access network that communicates over the air-interface, through one or more sectors, with wireless terminal devices, or by other names, depending on the particular application. The base station may be configured to interconvert received air frames with Internet Protocol (IP) packets as a router between the wireless terminal device and the rest of the access network, which may include an Internet Protocol (IP) communications network. The base station may also coordinate management of attributes for the air interface. For example, the Base station may be a network terminal (BTS) in Global System for Mobile Communications (GSM) or Code Division Multiple Access (CDMA), may be a network terminal (NodeB) in Wideband Code Division Multiple Access (WCDMA), may be an evolved Node B (eNB) in LTE, or an e-NodeB, and is not limited in the embodiment of the present invention.
The terminal of the internet of things related to the embodiment of the invention can be a handheld device with a wireless connection function or other processing devices connected to a wireless modem. For example, a wireless terminal device may communicate with one or more core networks via a Radio Access Network (RAN). The wireless terminal device may be a mobile terminal device, such as a computer with a mobile terminal device, a portable, pocket, handheld, computer-embedded or vehicle-mounted mobile device, an intelligent monitoring device, and an intelligent security device, which are not limited in the embodiments of the present invention.
The following detailed description of various embodiments of the invention refers to the accompanying drawings. It should be noted that the display sequence of the embodiment of the present invention only represents the sequence of the embodiment, and does not represent the merits of the technical solutions provided by the embodiments.
As shown in fig. 1, an embodiment of the present invention provides a method for scheduling an internet of things terminal, where the method includes:
s101, the base station determines the residual capacity of the terminal of the Internet of things.
In this embodiment, the terminal of the internet of things is a device with a wireless communication function, such as an intelligent monitoring device and an intelligent security device. Hereinafter, the "terminal of the internet of things" is simply referred to as "terminal".
The remaining power of the terminal may be reported from the terminal to the base station, and the base station may periodically receive the remaining power of the terminal reported from the terminal, and may also send a request for obtaining the remaining power of the terminal to the terminal. The base station may also determine the remaining power of the terminal in other manners, which is not limited in this embodiment.
S102, if the residual capacity of the terminal is larger than a set threshold, the base station calculates the energy efficiency of the terminal, and determines the times of scheduling the terminal by the base station based on the energy efficiency of the terminal, wherein the energy efficiency of the terminal is the data volume which can be transmitted by the terminal consuming unit transmission energy in unit time, and the lower the energy efficiency of the terminal is, the fewer the times of scheduling the terminal by the base station are.
In this embodiment, the energy efficiency of the terminal may be expressed as a ratio of the throughput of the terminal per unit time to the transmission energy of the terminal per unit time. According to the definition of the energy efficiency of the terminal, the method for the base station to calculate the energy efficiency of the terminal specifically includes: the base station calculates the throughput of the terminal in unit time and the transmission energy of the terminal in unit time, and calculates the energy efficiency of the terminal according to the calculated throughput of the terminal in unit time and the transmission energy of the terminal in unit time by a formula 1:
Figure BDA0001233964880000081
in the publication 1, EE denotes energy efficiency of the terminal, T denotes throughput of the terminal per unit time, and E denotes transmission energy of the terminal per unit time. The throughput of the terminal per unit time is the amount of data transmitted per unit time by the terminal, and may be expressed in bytes or bits. In practical applications, the energy efficiency of the terminal may also be calculated by other methods, which is not limited in this embodiment.
Assuming that the amount of data transmitted by terminal a and terminal B is the same in unit time, if the energy efficiency of terminal a is lower than that of terminal B, since the energy efficiency of terminal is the amount of data that can be transmitted by terminal B consuming unit transmission energy in unit time, the amount of data that can be transmitted by terminal a consuming unit transmission energy in unit time is lower than that of terminal B consuming unit transmission energy in unit time, and the energy consumed by terminal a transmitting unit data in unit time is higher than that consumed by terminal B transmitting unit data in unit time. That is, the lower the energy efficiency of the terminal, the lower the amount of data that can be transmitted by the terminal consuming unit transmission energy per unit time, and the higher the energy consumed by the terminal in transmitting unit data per unit time. Therefore, the base station can enable the terminal to transmit more data when the base station schedules the terminal with lower energy efficiency each time by reducing the times of scheduling the terminal with lower energy efficiency, and the purposes of saving the residual electric quantity of the terminal and prolonging the endurance time of the terminal are achieved.
Based on the principle, compared with the method for determining the number of times that the base station schedules the terminal based on a Proportional Fair (PF) algorithm in the existing scheduling technical scheme for the terminal of the internet of things, in S102, when the remaining power of the terminal is greater than a set threshold, the base station determines the number of times that the base station schedules the terminal based on the energy efficiency of the terminal, the lower the energy efficiency of the terminal is, the fewer the number of times that the base station schedules the terminal is, the number of times that the base station schedules the terminal with lower energy efficiency is reduced by the base station, the remaining power of the terminal is saved, and the endurance time of the terminal is prolonged.
Preferably, when the remaining power of the terminal is greater than the set threshold, the base station calculates the energy efficiency of the terminal, determines the scheduling priority of the terminal based on the energy efficiency of the terminal, and the lower the energy efficiency of the terminal is, the lower the scheduling priority of the terminal is. And the base station determines the times of the base station for scheduling the terminal based on the scheduling priority of the terminal according to the corresponding relation between the preset scheduling priority and the scheduling times, wherein the lower the scheduling priority is, the fewer the scheduling times are. Compared with a terminal with higher energy efficiency, the terminal with lower energy efficiency corresponds to a lower scheduling priority, and the time interval for the base station to schedule the terminal with lower energy efficiency is longer, so that data needing to be transmitted on the terminal with lower energy efficiency is gathered, and then more data are transmitted by the terminal when the base station schedules the terminal with lower energy efficiency each time, thereby meeting the scheduling requirement of the base station on the terminal and reducing the times for scheduling the terminal with lower energy efficiency.
The method for determining the scheduling priority of the terminal by the base station based on the energy efficiency of the terminal specifically comprises the following steps: the base station calculates the spectrum efficiency and the transmitted data amount of the terminal, and calculates the scheduling priority of the terminal according to formula 2:
Figure BDA0001233964880000091
wherein, P is the scheduling priority of the terminal, M is the spectral efficiency of the terminal, N is the transmitted data volume of the terminal, and k is a positive integer. k is determined according to the use environment of the terminal. As can be seen from equation 2, the lower the energy efficiency of the terminal, the lower the scheduling priority of the terminal.
S103, the base station sends scheduling information to the terminal based on the times of scheduling the terminal by the base station.
The scheduling information is used for instructing the terminal to perform data transmission.
In S103, the lower the energy efficiency of the terminal is, the fewer the number of times the base station schedules the terminal is, so for the terminal with lower energy efficiency, the fewer the number of times the base station schedules the terminal based on the determined number of times the base station schedules the terminal, and for the terminal with higher energy efficiency, the number of times the base station schedules the terminal with lower energy efficiency is reduced, the number of times the air interface schedules is reduced, and the control channel load is reduced, thereby achieving the purposes of saving the remaining power of the terminal and prolonging the endurance time of the terminal.
Optionally, after determining the remaining power of the terminal of the internet of things, if the remaining power of the terminal is less than or equal to the set threshold, the base station may send, to the terminal, indication information for indicating that the terminal is in a dormant state within a first preset time period. Because the power consumed by the terminal in the dormant state is low, the base station can further save the residual power of the terminal and prolong the endurance time of the terminal by indicating the terminal to enter the dormant state.
Because the terminal in the dormant state cannot receive and transmit data, when the base station needs to schedule the terminal in the dormant state, the terminal cannot receive the scheduling information sent by the base station. Optionally, after the base station sends, to the terminal, indication information for indicating that the terminal is in the dormant state within the first preset time period, the base station sends, using the sending indication information as a starting time, scheduling information to the terminal after the first preset time period, where the terminal is in the awake state. For example, the base station sets a timing duration of a timer of the base station to be a first preset duration, when the base station needs to schedule the terminal, the base station takes the sending indication information as a starting time, and when the timer of the base station times out, the base station sends the scheduling information to the terminal.
For example, as shown in fig. 2, a method for scheduling an internet of things terminal by a base station according to the embodiment includes:
the method comprises the following steps: and the base station receives the residual electric quantity of the terminal reported by the terminal.
Step two: and the base station judges whether the residual electric quantity of the terminal is greater than a set threshold value. And if the residual capacity of the terminal is greater than the set threshold value, executing a step three. And if the residual capacity of the terminal is less than or equal to the set threshold, executing the step four.
Step three: the base station calculates a scheduling priority of the terminal based on the energy efficiency of the terminal, and transmits scheduling information to the terminal based on the scheduling priority of the terminal. And the base station completes the scheduling of the terminal.
The specific method for the base station to calculate the scheduling priority of the terminal based on the energy efficiency of the terminal is as follows: and the base station calculates the throughput in unit time of the terminal and the transmission energy in unit time of the terminal, and calculates the energy efficiency of the terminal according to the throughput in unit time of the terminal and the transmission energy in unit time of the terminal. The base station calculates the spectral efficiency of the terminal and the data volume sent by the terminal, and calculates the scheduling priority of the terminal according to the spectral efficiency of the terminal, the data volume sent by the terminal and the energy efficiency of the terminal, wherein the lower the energy efficiency of the terminal is, the lower the scheduling priority of the terminal is.
Step four: the base station sends indication information for indicating that the terminal is in a dormant state within a first preset time length to the terminal, and sets the timing time length of a timer of the base station as the first preset time length by taking the sent indication information as an initial time.
Step five: the base station judges whether the timer of the base station is overtime. And if the timer of the base station is overtime, executing step six. If the timer of the base station is not overtime, the base station continuously judges whether the timer of the base station is overtime.
Step six: and if the base station needs to schedule the terminal, the base station sends scheduling information to the terminal, and the base station finishes scheduling the terminal. And if the base station does not need to schedule the terminal, executing the step four.
In the scheduling method of the terminal of the internet of things provided by the embodiment of the invention, the base station determines the residual electric quantity of the terminal of the internet of things, calculates the energy efficiency of the terminal for the situation that the residual electric quantity of the terminal is larger than the set threshold value, determines the times for scheduling the terminal by the base station based on the energy efficiency of the terminal, and sends scheduling information to the terminal based on the times for scheduling the terminal by the base station. The lower the energy efficiency of the terminal is, the fewer the times of dispatching the terminal by the base station is, and the times of dispatching the terminal by the base station is determined by the base station through the energy efficiency of the terminal obtained by calculation, so that the times of dispatching the terminal with the lower energy efficiency by the base station are reduced, the times of dispatching the terminal by the air interface are reduced, and the control channel load is reduced, thereby achieving the purposes of saving the residual electric quantity of the terminal and prolonging the endurance time of the terminal.
As shown in fig. 3, an embodiment of the present invention provides a method for scheduling an internet of things terminal, where the method includes:
s301, the terminal of the Internet of things receives scheduling information sent by the base station.
And the residual capacity of the terminal is greater than a set threshold value.

Optionally, before the terminal receives the scheduling information sent by the base station, the terminal reports the remaining power of the terminal to the base station. The terminal may report the remaining power of the terminal to the base station periodically, or report the remaining power of the terminal to the base station after the base station sends a request for obtaining the remaining power of the terminal to the terminal, which is not limited in this embodiment.

In the scheduling process of the terminal of the internet of things, the terminal receives scheduling information sent by a base station and carries out data transmission according to the scheduling information, wherein the scheduling information is sent to the terminal when the base station schedules the terminal based on the times of scheduling the terminal by the base station.

Preferably, after the terminal receives the indication information indicating that the terminal is in the dormant state within the first preset time period, although the terminal of the internet of things is allowed to have a certain time delay during data transmission in practical application, the base station still needs to transmit data through the terminal. After the terminal enters the awakening state, whether the base station sends scheduling information is monitored through the detection channel, and when the terminal monitors that the base station sends the scheduling information through the detection channel, the terminal receives the scheduling information and carries out data transmission according to the scheduling information.
Preferably, after the terminal enters the wake-up state and monitors whether the base station sends the scheduling information, when the terminal does not monitor that the base station sends the scheduling information after the terminal enters the wake-up state as an initial time and the terminal experiences a second preset duration, the terminal enters the sleep state from the wake-up state in order to save the remaining power of the terminal and prolong the endurance time of the terminal.
