Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
The present disclosure provides an information transmission method for an application server in the internet of things to send downlink information to a terminal, and some embodiments of the communication method of the present disclosure are described below with reference to fig. 1.
Fig. 1 is a flow chart of some embodiments of the disclosed communication method. As shown in fig. 1, the method of this embodiment includes: steps S102 to S108.
Step S102, the platform of the Internet of things acquires downlink information sent by the application server to the terminal.
Each application server sends downlink information to the connected terminal, and the downlink information can firstly reach the platform of the Internet of things. The platform of the internet of things can determine an application server from which the downlink information comes, and can determine terminals to which the downlink information is sent according to the destination address. In some cases, the application server may send a command to all terminals connected to the application server, for example, instruct all terminals to report current location information, temperature information, and the like. In this case, the internet of things platform may determine which receiving terminals of the downlink information are through registration information or binding information of the terminal and the application server. That is, the internet of things platform may determine, for each piece of downlink information, an application server and a terminal corresponding to the downlink information, and may determine application servers and terminals corresponding to all pieces of acquired downlink information.
As shown in table 1, the internet of things platform may determine application servers, such as application servers 1-m, to which downlink information relates, and may also determine to which terminals each application server sends the downlink information, such as application server m sends the downlink information to terminals m1 to mk, for k terminals in total.
TABLE 1
| Application server 1 | Terminal 11 | Terminal 12 | …… | Terminal 1n |
| Application server 2 | Terminal 21 | Terminal 22 | …… | Terminal 2l |
| …… | …… | …… | …… | …… |
| Application server m | Terminal m1 | Terminal m2 | …… | Terminal mk |
And step S104, the Internet of things platform determines a base station corresponding to the downlink information according to the connection relation between the terminal and the base station.
The internet of things platform can determine downlink information corresponding to the base station according to the terminal corresponding to the downlink information and the base station corresponding to the terminal. Namely, the internet of things platform can determine downlink information corresponding to the base station according to the connection relationship between the terminal and the base station. For example, the internet of things platform may determine a base station corresponding to the terminal according to the received uplink information of the terminal. Uplink information sent by the terminal to the application server needs to be sent to the base station first, the uplink information can carry information such as base station identification, and then the internet of things platform can determine base station information corresponding to the terminal. The terminal can also report the information of the base station connected with the terminal to the platform of the Internet of things. The Internet of things platform can acquire the base station corresponding to the terminal through uplink information or active report of the terminal and determine downlink information corresponding to the base station, so that the problems that the corresponding relation between the terminal and the base station cannot be obtained and information issuing cannot be carried out on the base station cannot be achieved by the Internet of things platform at present are solved.
Further, the internet of things platform can determine the relationship among the base station, the terminal and the application (or the application server) corresponding to all the acquired downlink information. As shown in table 2, the internet of things platform may determine each base station, for example, base station 1 — base station w, corresponding to the downlink information. The internet of things platform may determine an application and a terminal pair corresponding to each base station, for example, an application and a terminal pair related to downlink information corresponding to a base station w include: application 1-terminal 11, application 1-terminal 1n, application m-terminal mk, etc. That is, the downlink information corresponding to the base station w includes: downlink information transmitted from the application 1 to the terminal 11, downlink information transmitted from the application 1 to the terminal 1n, downlink information transmitted from the application m to the terminal mk, and the like.
TABLE 2
And S106, dividing downlink information corresponding to the base station into different groups by the platform of the Internet of things according to the processing capacity of the base station corresponding to the terminal.
In some embodiments, the processing capability of the base station includes a maximum amount of parallel processing of downlink information by the base station. The maximum amount of the downlink information processed by the base station in parallel can be determined according to the resource amount of the base station. The resource amount information of the base station may be determined according to a record of the base station when deployed. The Internet of things platform determines the quantity of downlink information in each group corresponding to the base station according to the maximum quantity of the downlink information processed by the base station in parallel and the total quantity of the downlink information corresponding to the base station; and the Internet of things platform divides the downlink information corresponding to the base station into different groups according to the quantity of the downlink information in each group corresponding to the base station.
For example, the internet of things platform determines the number of packets according to the ratio of the total number of downlink information corresponding to the base station to the maximum number of downlink information processed by the base station in parallel, and the number of downlink information in each packet is less than or equal to the maximum number of downlink information processed by the base station in parallel. For example, the total amount of the downlink information corresponding to the base station is 100, the maximum amount of the downlink information processed in parallel by the base station is 20, and the internet of things platform may divide the downlink information corresponding to the base station into 5 groups, where each group includes 20 pieces of downlink information.
In some embodiments, the internet of things platform may disperse downlink information corresponding to each application server in each group as much as possible, and each group may include downlink information corresponding to a plurality of application servers. The internet of things platform can determine the amount of downlink information of each application server contained in each group according to the amount of the downlink information in each group corresponding to the base station and the amount of the application servers corresponding to the base station. For example, if the number of downlink information in each group corresponding to the base station is 20 and there are 10 application servers corresponding to the base station, each group may include 2 pieces of downlink information of the 10 application servers.
In some embodiments, the internet of things platform may further divide downlink information corresponding to the base station into different groups according to the processing capability and the application priority of the base station.
Further, the internet of things platform determines the quantity of downlink information in each group corresponding to the base station according to the processing capacity of the base station, and determines the downlink information contained in each group according to the application priority. Wherein, the higher the priority of the application is, the downlink information corresponding to the application is divided into packets which are sent preferentially. The application corresponds to an application server. Different packets may be scheduled to be transmitted at different times, for example, the downlink information corresponding to the application with the highest application priority may be scheduled in the earliest transmitted packet.
As shown in table 3, the internet of things platform may group downlink information corresponding to each base station. For example, packet 1 of base station 1 includes: downlink information transmitted by the application 1 to the terminals 11 and 12, downlink information transmitted by the application m to the terminals m1 and m2, and the like.
TABLE 3
Step S108, the platform of the Internet of things sends downlink information in different groups to the base station at different moments, so that the base station sends the received downlink information to the terminal at different moments.
The downlink information for a base station is divided into different packets, each packet corresponding to a different transmission time instant. In some embodiments, the internet of things platform may send each packet to the corresponding base station at preset time intervals.
In some embodiments, the sending time interval of the downlink information of different packets corresponding to the base station may be determined according to the processing capability of the base station. For example, the processing capability of the base station includes the time for the base station to process the downlink information. And the Internet of things platform sends the downlink information in different groups to the base station according to the time interval corresponding to the base station. The time for the base station to process the downlink information may be determined according to the historical statistics. The internet of things platform can determine the time for the base station to process the downlink information according to the time from the transmission of the downlink information to the reception of the corresponding uplink response information. For example, the internet of things platform may count 20 pieces of downlink information sent to the base station, and on average, 0.1s may receive 20 corresponding uplink replies, so that it may be determined that the time for the base station to process 20 pieces of downlink information in parallel is 0.1s, and further, the time interval of each packet is set to 0.1s.
In some embodiments, the internet of things platform sends downlink information in a next packet to the base station in response to receiving a preset number of uplink responses corresponding to the downlink information in the current packet. The internet of things platform can dynamically adjust the sending time of each group according to the received uplink response state. And when the Internet of things platform receives the condition that the uplink response corresponding to the current group reaches the preset number, sending downlink information of the next group to the base station. For example, the internet of things platform may send downlink information of a next packet to the base station when receiving all uplink responses corresponding to the current packet.
In some embodiments, the internet of things platform may further adjust the number of downlink information in the current packet according to the number of uplink responses corresponding to the downlink information in the previous packet that is not received, and send the downlink information in the current packet to the base station. For example, there are 5 uplink responses corresponding to the downlink information in the previous packet that the internet of things platform has not received, the number of the downlink information in the current packet may be adjusted from 20 to 15, and the reduced 5 downlink information in the current packet may be adjusted to other packets that do not reach the maximum number, or adjusted to the last packet to be sent. And under the condition of considering the application priority, adjusting the grouping of the downlink information according to the application priority. And preferentially adjusting the downlink information corresponding to the application with the lower priority into the subsequently sent packet.
The internet of things platform can have different grouping numbers aiming at the grouping mode of each base station, and the time for sending the grouping by each base station can also be different. The success rate of downlink information transmission can be effectively improved by grouping downlink information by considering the capability of the base station for processing the information in parallel and arranging the transmission time of different groups according to the processing condition of the base station.
In the method of the embodiment, after receiving the downlink information sent by the application server, the internet of things platform divides the downlink information corresponding to the base station into different groups according to the processing capacity of the base station, and issues the different groups to the base station at different times. Therefore, a large amount of concurrent downlink information can be dispersedly sent to the base station, the probability of occurrence of the condition that the large amount of information cannot be processed by the base station is reduced, the sending success rate of the downlink information sent to the terminal by the application server in the networking is improved, the retransmission times of the downlink information are reduced, the system resources are saved, and the information sending efficiency is improved.
