In the embodiment of the invention, the network equipment can determine the resource allocation sequence corresponding to the plurality of service data by determining the service type of each service data and configuring different resource allocation priorities for the services of three different service types, thereby improving the reliability of service transmission and the efficiency of resource allocation.
The method and the device for resource allocation provided by the embodiment of the invention can be applied to a wireless communication system, and take the wireless communication system as a 5G communication system as an example, as shown in fig. 1, the 5G communication system comprises an internet of things terminal 101, an internet of things terminal 102, an internet of things terminal 103 and network equipment 104. In general, in practical applications, the connection between the above-mentioned devices or service functions may be a wireless connection, and for convenience and intuitiveness, the connection relationship between the devices is schematically shown by a solid line in fig. 1.
The internet of things terminal (including the internet of things terminal 101, the internet of things terminal 102 and the internet of things terminal 103) may send a resource allocation request message to the network device 104, and specifically, the resource allocation request message sent by the internet of things terminal 101 to the network device 104 includes the size of the service data requested to be reported by the internet of things terminal 101.
The network device 104 may determine a service type of a service corresponding to the internet of things terminal 101 according to a size of service data requested to be reported by the internet of things terminal (for example, the internet of things terminal 101), and may determine a resource allocation sequence corresponding to each service data in the plurality of service data after determining the service type of the service data. In the embodiment of the present invention, the network device 104 may also determine whether the channel quality indicator (channel quality indication, CQI) corresponding to a certain data reporting service is less than or equal to a CQI threshold, etc.
By way of example, taking the network device 104 in fig. 1 as a commonly used base station, the hardware structure of the network device 104 provided in the embodiment of the present invention is described. As shown in fig. 2, a base station provided by an embodiment of the present invention may include: 20 parts and 21 parts.

The resource allocation method and the resource allocation device provided by the embodiment of the invention are applied to the scene that a plurality of terminals of the Internet of things request network equipment to allocate resources for the terminals. After the plurality of terminals of the internet of things send the resource allocation request to the network device, the network device may determine the service types corresponding to the plurality of service data based on the sizes of the service data included in the plurality of resource allocation request messages, so as to determine the resource allocation sequence of the plurality of service data, that is, determine which service is allocated with resources first and then which service is allocated with resources.
As shown in fig. 3, the resource allocation method provided in the embodiment of the present invention may include S101-S103.
S101, network equipment acquires resource allocation request messages sent by a plurality of Internet of things terminals.
The resource allocation request message sent by one internet of things terminal comprises the size of the service data requested to be reported by the internet of things terminal.
It should be understood that the terminal of the internet of things can comprise meters such as a water meter, an electric meter and a gas meter, can also comprise lighting equipment such as a street lamp, and can also comprise a bicycle, a tracker and the like.
S102, the network equipment determines the service type of each service data in the plurality of service data according to the size of the service data requested to be reported by each Internet of things terminal in the plurality of Internet of things terminals.
Wherein the service type of one service data comprises one of the following: event reporting service, heartbeat reporting service or data reporting service.
It can be understood that one internet of things terminal corresponds to one service, that is, service data included in a resource allocation request message sent by one internet of things terminal may correspond to one service.
The data reporting service is a service of periodically sending service data, for example, a certain ammeter can send electricity consumption and/or residual electricity to the network device every 1 day, and the sent service data volume is greater than the event reporting service and the heartbeat reporting service.
The event reporting service is a service for sending service data in a non-periodic manner, for example, when a certain voltage value is smaller than a voltage threshold value, or the shell of the internet of things terminal is damaged, the internet of things terminal can actively report the data corresponding to the situations.
The heartbeat reporting service is also a service for periodically sending service data, the heartbeat reporting service is used for informing the network equipment whether the terminal of the internet of things is in a normal state, when the network equipment determines that the terminal of the internet of things is in the normal state, the network equipment can determine that the service data corresponding to the data reporting service and/or the event reporting service are correct data, and the data volume corresponding to the heartbeat reporting service is smaller than the data volume corresponding to the event reporting service.
In an implementation manner of the embodiment of the present invention, S102 specifically includes: step A-step B.
And step A, the network equipment determines whether the size of service data corresponding to the target service is smaller than or equal to a first data volume threshold value.
The size of the service data corresponding to the target service is the size of the service data requested to be reported by the target internet of things terminal, and the target internet of things terminal is one of a plurality of internet of things terminals, namely the target service is one of a plurality of services.
And B, under the condition that the size of the service data corresponding to the target service is smaller than or equal to the first data volume threshold, the network equipment determines that the service type of the target service is the heartbeat reporting service.
In one implementation, when the size of the service data corresponding to the target service is greater than the first data volume threshold, the network device may further determine whether the service data corresponding to the target service is less than the second data volume threshold, and in particular, the first data volume threshold is less than the second data volume threshold.
In connection with the above description of the embodiments, it should be understood that the data volume corresponding to the heartbeat reporting service < the data volume corresponding to the event reporting service < the data volume corresponding to the data reporting service. Based on this, when the network device determines that the service data corresponding to the target service is smaller than the second data volume threshold (before that, the network device has determined that the service data corresponding to the target service is greater than the first data volume threshold), the network device may determine that the target service is an event reporting service; otherwise, the network device determines that the target service is the data reporting service when the service data corresponding to the target service is greater than or equal to the second data volume threshold.
In an implementation manner of the embodiment of the present invention, the network device may further determine a service type of each service data in the plurality of service data according to an international mobile equipment identification code (international mobile equipment identity, IMEI) of each of the plurality of internet of things terminals.
Specifically, the resource allocation request message sent by the one internet of things terminal may further include an IMEI of the internet of things terminal, and the network device may determine a service type corresponding to each IMEI according to the IMEI of each internet of things terminal in the plurality of internet of things terminals and a corresponding relationship between the plurality of IMEIs stored in the network device and service types, user power consumption and event requirements, that is, determine a service type of each service data.
Thus, the network device may determine a service type of each service data in the plurality of service data.
S103, the network equipment determines the resource allocation sequence corresponding to the plurality of service data according to the service type of each service data in the plurality of service data.
The resource allocation priority of the event reporting service is higher than the resource allocation priority of the heartbeat reporting service, and the resource allocation priority of the heartbeat reporting service is higher than the resource allocation priority of the data reporting service.
It should be understood that the resource allocation priority of the event reporting service is higher than that of the heartbeat reporting service, which means that the network device allocates resources for the event reporting service first, then allocates resources for the heartbeat reporting service, and similarly allocates resources for the data reporting service after allocating resources for the heartbeat reporting service.
It should be noted that, through the step S103, the network device is equivalent to dividing the plurality of service data into three different resource allocation priorities, and in the case that the service types of two certain service data are different, the network device may directly determine which service is allocated with the resources preferentially; when the service types of some two services are the same, the network device may determine which service is preferentially allocated with resources through the following steps.
According to the resource allocation method provided by the embodiment of the invention, network equipment firstly acquires resource allocation request messages sent by a plurality of Internet of things terminals, wherein the resource allocation request message sent by one Internet of things terminal comprises the size of service data requested to be reported by the Internet of things terminal; then, the network device determines the service type of each service data in the plurality of service data according to the size of the service data requested to be reported by each of the plurality of internet of things terminals, wherein the service type of one service data is one of the following: event reporting service, heartbeat reporting service or data reporting service; furthermore, the network device may determine, according to the service type of each service data in the plurality of service data, a resource allocation sequence corresponding to the plurality of service data, where a resource allocation priority of an event reporting service is higher than a resource allocation priority of a heartbeat reporting service, and the resource allocation priority of the heartbeat reporting service is higher than the resource allocation priority of the data reporting service, that is, the network device may determine to allocate resources for the event reporting service first, allocate resources for the heartbeat reporting service, and allocate resources for the data reporting service at last. In the embodiment of the invention, the network equipment can determine the resource allocation sequence corresponding to the plurality of service data by determining the service type of each service data and configuring different resource allocation priorities for the services of three different service types, thereby improving the reliability of service transmission and the efficiency of resource allocation.
In one implementation manner of the embodiment of the present invention, the step S103 specifically includes step C-step D.
And C, the network equipment determines whether CQI corresponding to each data reporting service in the plurality of data reporting services is smaller than or equal to a CQI threshold value, and whether energy consumption corresponding to each data reporting terminal in the plurality of data reporting terminals is smaller than or equal to an energy consumption threshold value.
The data reporting services are services of which the service types are data reporting services in the plurality of service data, and the plurality of data reporting terminals are Internet of things terminals corresponding to the plurality of data reporting services.
It should be understood that, for an internet of things terminal, if the service type corresponding to the service data included in the resource allocation request message sent by the internet of things terminal is the data reporting service, the internet of things terminal is the data reporting terminal.
And D, when the CQI corresponding to the first data reporting service is smaller than or equal to the CQI threshold value and the energy consumption corresponding to the first data reporting terminal is smaller than or equal to the energy consumption threshold value, the network equipment determines that resources are preferentially allocated to the first data reporting service in the plurality of data reporting services.
The first data reporting service is one of the plurality of data reporting services, and the first data reporting terminal is an internet of things terminal corresponding to the first data reporting service.
It can be understood that the CQI corresponding to the first data reporting service being less than or equal to the CQI threshold indicates that the channel quality corresponding to the first data reporting service is poor; the fact that the energy consumption corresponding to the first data reporting terminal is smaller than or equal to the energy consumption threshold value indicates that the energy consumption requirement of the first data reporting terminal is lower. In the embodiment of the invention, the network equipment can allocate resources for the data reporting service with poor channel quality and lower corresponding terminal energy consumption requirement preferentially in a plurality of data reporting services, so that the accuracy of data transmission is improved, and the number of times of error retransmission is reduced.
In another implementation manner, when the energy consumption corresponding to the first data reporting terminal is greater than the energy consumption threshold, the network device may determine to put the resource allocation sequence of the first data reporting service back, for example, allocate resources for the first data reporting service last in the multiple data reporting services.
In an implementation manner of the embodiment of the present invention, the network device may further determine a resource allocation sequence of each of the plurality of data reporting services based on a priority value corresponding to the data reporting service in the plurality of data reporting services. Specifically, the method can be realized through the following steps E-G.
And E, the network equipment determines the priority value corresponding to each data reporting service in the plurality of data reporting services.
Wherein, the priority value corresponding to one data reporting service satisfies:
specifically, pri represents a priority value corresponding to the data reporting service, C represents a CQI corresponding to the data reporting service, re represents an average resource occupation amount corresponding to the data reporting service, and W represents a weight coefficient.
It should be understood that the average resource occupation amount corresponding to the data reporting service is an average value of resource amounts required by the internet of things terminal corresponding to the data reporting service to perform the data transmission service for multiple times.
And F, the network equipment determines whether the priority value corresponding to the second data reporting service is larger than the priority value corresponding to the third data reporting service.
The second data reporting service and the third data reporting service are one of the plurality of data reporting services.
And G, when the priority value corresponding to the second data reporting service is greater than the priority value corresponding to the third data reporting service, the network equipment determines that the resource allocation priority of the second data reporting service is higher than the resource allocation priority of the third data reporting service.
In the embodiment of the present invention, when the priority value corresponding to the second data reporting service is greater than the priority value corresponding to the third data reporting service, the network device may determine that the resource allocation priority of the second data reporting service is higher than the resource allocation priority of the third data reporting service, that is, between the second data reporting service and the third data reporting service, the network device preferentially allocates resources for the second data reporting service;
when the priority value corresponding to the second data reporting service is smaller than the priority value corresponding to the third data reporting service, the network device may determine that the resource allocation priority of the second data reporting service is lower than the resource allocation priority of the third data reporting service, that is, before the second data reporting service and the third data reporting service, the network device is limited to allocate resources for the third data reporting service.
In an implementation manner, in combination with the step D, when the CQI corresponding to the fourth data reporting service is less than or equal to the CQI threshold and the energy consumption corresponding to the fourth data reporting terminal (i.e., the internet of things terminal corresponding to the fourth data reporting service) is less than or equal to the energy consumption threshold, the network device may also determine, based on the step E-the step G, to allocate resources preferentially for the first data reporting service or the fourth data reporting service. Specifically, when the priority value corresponding to the first data reporting service is greater than the priority value corresponding to the fourth data reporting service, the network device preferentially allocates resources for the first data reporting service.
Similarly, the second data reporting service and the third data reporting service may be data reporting services with CQI greater than a CQI threshold and/or corresponding energy consumption greater than an energy consumption threshold.
In one implementation manner of the embodiment of the present invention, after the step G, the method for allocating resources provided by the embodiment of the present invention further includes a step H-step I.
And step H, the network equipment determines whether the position information of the second data reporting terminal changes.
The second data reporting terminal is an internet of things terminal corresponding to the second data reporting service.
It should be understood that the network device may determine (or acquire) the location information of the second data reporting terminal by using a preset time interval, so as to determine whether the location information of the second data reporting terminal changes.
And step I, under the condition that the position information of the second data reporting terminal is unchanged, the network equipment determines that the priority value corresponding to the second data reporting service is unchanged.
It can be understood that the position information of the second data reporting terminal is unchanged, which indicates that the second data reporting terminal is a static internet of things terminal, such as an ammeter, a water meter, a gas meter, and the like, and further indicates that the channel environment of the second data reporting terminal is unchanged. As can be seen by combining the formula in the step E, the average resource occupation amount (Re) corresponding to the second data reporting service is unchanged, and the network device may determine that the Pri of the second data reporting service is unchanged, that is, the priority value corresponding to the second data reporting service is unchanged.
In another implementation manner, in the case that the location information of the second data reporting terminal changes, the network device may determine (or update) the priority value corresponding to the second data reporting service before allocating resources for the second data reporting terminal each time or determining the resource allocation sequence of the plurality of service data each time.
It should be noted that, in the step H-step I, the second data reporting service is taken as an example for illustration, and it should be understood that all the data reporting services (including the third data reporting service) may execute the related method provided by the present invention according to the above step H-step I.
In the embodiment of the invention, for the service with the service type of event reporting service or heartbeat reporting service, the network equipment can determine the resource allocation sequence of different services in the same service type based on the emergency degree of different services in the same service type. Specifically, the method can comprise the steps J-K.
And step J, the network equipment determines whether the emergency degree corresponding to the first event reporting service is higher than the emergency degree corresponding to the second event reporting service.
The first event reporting service and the second event reporting service are services of which the service types in the plurality of service data are event reporting services.
And step K, under the condition that the emergency degree corresponding to the first event reporting service is higher than that corresponding to the second event reporting service, the network equipment determines that the resource allocation priority of the first event reporting service is higher than that of the second event reporting service.
It should be understood that the resource allocation priority of the first event reporting service is higher than the resource allocation priority of the second event reporting service, which indicates that the network device allocates resources for the first event reporting service first and then allocates resources for the second event reporting service. In the embodiment of the invention, in a plurality of event reporting services, network equipment firstly allocates resources for the event reporting service with the highest emergency degree.
Similarly, in the multiple heartbeat reporting services, the network device allocates resources for the heartbeat reporting service with the highest emergency degree at first.
It should be appreciated that, each time resources are allocated to a plurality of event reporting services, the resource allocation priority of the plurality of event reporting services is unchanged, for example, in a case where it is determined that the emergency degree of the first event reporting service is higher than the emergency degree of the second event reporting service, the resource allocation priority of the first event reporting service is always higher than the resource allocation priority of the second event reporting service. Similarly, when resources are allocated to the plurality of heartbeat reporting services, the priority of resource allocation of the plurality of heartbeat reporting services is also unchanged.
For easy understanding, the resource allocation method provided by the embodiment of the present invention is described in the following as a complete example.
The network device is assumed to acquire resource allocation request messages sent by 8 internet of things terminals, as shown in table 1 and table 2, the 8 internet of things terminals correspond to 8 services, and the service types of the network device are determined to be a first event reporting service, a second event reporting service, a first heartbeat reporting service, a second heartbeat reporting service, a first data reporting service, a second data reporting service, a third data reporting service and a fourth data reporting service.
The respective emergency degrees of the 2 event reporting services and the 2 heartbeat reporting services shown in table 1 are shown, the emergency degree of the first event reporting service is high, the emergency degree of the second event reporting service is low, and it is indicated that the emergency degree of the first event reporting service is higher than the emergency degree of the second event reporting service.
The priority value corresponding to each data reporting service in the 4 data reporting services and whether the CQI corresponding to the 4 data reporting services is less than or equal to the CQI threshold are shown in table 2, where yes indicates that the CQI corresponding to the data reporting service is less than or equal to the CQI threshold, and whether the energy consumption of the data reporting terminal corresponding to the 4 data reporting services is less than or equal to the energy consumption threshold, where yes indicates that the energy consumption corresponding to the data reporting terminal is less than or equal to the energy consumption threshold.

As can be seen from table 1, since the emergency degree corresponding to the first event reporting service is higher than the emergency degree corresponding to the second event reporting service, the network device preferentially allocates resources for the first event reporting service in the 2 event reporting services, and similarly, the network device preferentially allocates resources for the second heartbeat reporting service in the 2 heartbeat reporting services.
As can be seen from table 2, since the CQI corresponding to the third data reporting service is less than or equal to the CQI threshold, and the energy consumption corresponding to the third data reporting terminal (i.e., the internet of things terminal corresponding to the third data reporting service) is less than or equal to the energy consumption threshold, and when there are the 4 data reporting services and only the third data reporting service meets the two conditions (i.e., CQI and energy consumption), the network device determines that resources are preferentially allocated to the third data reporting service in the 4 data reporting services; and because the priority value corresponding to the fourth data reporting service is greater than the priority value corresponding to the first data reporting service, the priority value corresponding to the first data reporting service is greater than the priority value corresponding to the second data reporting service, so that the network equipment determines that the sequence of resource allocation in the 4 data reporting services is the third data reporting service, the fourth data reporting service, the first data reporting service and the second data reporting service in sequence.
In combination with table 1 and table 2, since the resource allocation priority of the event reporting service is higher than the resource allocation priority of the heartbeat reporting service, the resource allocation priority of the heartbeat reporting service is higher than the resource allocation priority of the data reporting service, the network device determines that the resource allocation order of the 8 services is the first event reporting service, the second heartbeat reporting service, the first heartbeat reporting service, the third data reporting service, the fourth data reporting service, the first data reporting service and the second data reporting service in sequence.
