Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

An embodiment of the present invention provides a base station access method, as shown in FIG. 1, the method includes:

101. When detecting that the mobile terminal is in a coverage area of multiple base stations, the mobile terminal sends a connection initialization request to multiple base stations covering the area.

Wherein, the coverage area of multiple base stations refers to an overlapping area among coverage areas of multiple different base stations. The connection initialization request sent by the mobile terminal is used to send the mobile terminal's own information and required service conditions to the base station, and the base station calculates and feeds back the corresponding index parameters, so that the mobile terminal selects a current best service among multiple base stations according to these index parameters. A suitable base station establishes the connection.

102. In response to the base station receiving the connection initialization request sent by the mobile terminal, the base station calculates various index parameters based on the connection initialization request.

103. The mobile terminal receives various index parameters respectively sent by each of the base stations.

104. The mobile terminal selects a target base station from among the multiple base stations based on various index parameters corresponding to the base stations, and sends a connection establishment request to the target base station.

Compared with the existing technology, the embodiment of the present invention can comprehensively consider the channel signal-to-noise ratio, base station computing resources, user QoS, and mobile terminal standby time when establishing a connection between an industrial Internet-oriented terminal device and a base station in a 5G communication network. By processing data volume and other factors, the target base station with the best data processing effect can be selected among multiple base stations to establish a communication connection, which can make full use of network resources and improve user service quality.

Another embodiment of the present invention provides a base station access method, as shown in FIG. 2, the method includes:

201. When detecting that the mobile terminal is in an area covered by multiple base stations, the mobile terminal sends a connection initialization request to multiple base stations covering the area.

Wherein, the coverage area of multiple base stations refers to an overlapping area among coverage areas of multiple different base stations. Exemplarily, in the network scenario shown in FIG. 2 , a terminal device (UE 1 ) is covered by two base stations (Cell 1 and Cell 2 ). This figure only shows two base stations as an example, and it can be understood that the number of coverage overlapping areas is the number of base stations actually covered by this location.

Wherein, the connection initialization request carries the location information of the mobile terminal, the amount of data to be processed by the mobile terminal, and the required QoS service level. As shown in Figure 2, UE 1 can send connection initialization requests to Cell1 and Cell 2 respectively, and the request message includes the size of the data to be processed carried by the terminal D, the geographic location of the terminal (X1, Y1), and the QoS to be provided grade information, etc.

202. In response to the base station receiving the connection initialization request sent by the mobile terminal, the base station calculates various index parameters based on the connection initialization request and the computing resources of the mobile edge computing MEC server of the base station .

Wherein, the various index parameters include: any one or any combination of signal-to-noise ratio, time required for service completion, and whether QoS service level can be satisfied.

For the embodiment of the present invention, after receiving the user connection initialization request, the base station parses the initialization request message to obtain basic data information about the user terminal. Then, the base station calculates corresponding indicators based on its remaining MEC server storage resources, memory and other information, such as whether it can meet the QoS required by the user, or the time required to process the user's data.

In the embodiment of the present invention, MEC (Mobile Edge Computing, mobile edge computing technology) refers to deploying MEC servers with IT service environment and computing and storage capabilities at the edge of the network closest to users to reduce network operations and service interactions delay and improve user service quality.

The base station calculates the time required for the completion of the service, including: the base station calculates a first time based on the current operating status of the MEC server, and the first time is used to represent the waiting time required for the MEC server to process new data The base station calculates a second duration based on the amount of data to be processed by the mobile terminal and the computing resources of the MEC server, and the second duration is used to characterize the duration required for the base station to process the amount of data to be processed; The base station uses the sum of the first duration and the second duration as the duration required for the completion of the service.

Exemplarily, the calculation of the service delay by the base station is taken as an example below to describe a feasible method adopted by the base station for calculating indicators, and other indicators can be deduced in the same way.

Assuming that the current MEC server of the base station Cell 1 is already operating at full capacity, it takes a waiting time t1 to provide computing resources to process requests from new connection terminals. After its resources are released, the time required to process the requested data can be calculated by the following formula: t ₂ =f(D,χ), where χ is the computing resource of the MEC server.

It can be further inferred that in the function f, the variable t2 has an inverse correlation with the size of the data D to be processed, and a positive correlation with the computing resource χ.

Therefore, if the user is connected to the base station, the total time t required to complete the service can be calculated according to the formula: t=t ₁ +t ₂ .

It should be noted that, in order to simplify the calculation, the waiting time and calculation time are mainly considered here, and the communication round-trip consumption delay and other time are omitted, which can be superimposed to the total time by referring to the algorithm.

203. The mobile terminal receives various index parameters respectively sent by each of the base stations.

For the embodiment of the present invention, the base station encapsulates these data in the response message according to the agreed format, and returns it to the user terminal, and the user terminal maintains a base station list {C ₁ , C ₂ ,...,C _n }( n represents the number of base stations covering the terminal equipment).

204. For each of the base stations, the mobile terminal performs a weighted score on each index parameter of the base station.

其中，m表示终端设备参考的指标数量，X表示该基站当前所处状态对于终端设备的得分情况。然后用户终端向得分最高的基站发起连接请求，完成后续的数据交互通信。For the embodiment of the present invention, weighted scoring or further mathematical processing is performed according to various index data returned by the base station. For example, the terminal can score the base station according to the linear weighting model. Assuming that the index parameters returned by the base station are x ₁ , x ₂ ,...,x _m , and the weighting system assigned by the terminal to each index is w ₁ , w ₂ ,...,w _m , then the weighted sum X can be calculated according to Formula calculation:

Wherein, m represents the number of indicators referenced by the terminal device, and X represents the score of the current state of the base station for the terminal device. Then the user terminal initiates a connection request to the base station with the highest score to complete the subsequent data interactive communication.

205. The mobile terminal uses the base station with the highest weighted score value as the target base station.

206. The mobile terminal sends a connection establishment request to the target base station.

207. Establish a communication connection between the mobile terminal and the target base station.

Optionally, when the duration of establishing a communication connection reaches a preset duration, or the location of the mobile terminal changes beyond a preset range, the mobile terminal resends a connection initialization request to multiple base stations covering the current area, and based on each The target base stations are reselected among the plurality of base stations according to various index parameters corresponding to the base stations.

Exemplarily, when the mobile terminal establishes a connection with the current base station for 5 minutes, the connection initialization request is resent to each base station covered by the current area, so that the mobile terminal reselects the most suitable base station in the current state to establish a connection; or, when When the position of the mobile terminal has changed by more than 20 meters, the connection initialization request is resent to each base station covered by the current area, so that the mobile terminal reselects the most suitable base station in the current state to establish a connection.

In the embodiment of the present invention, when the preset condition is satisfied, the mobile terminal resends the connection initialization request to each base station, and reselects the most suitable base station in the current state to establish a connection, so that the mobile terminal can avoid the connection with the base station all the time after the connection is established. A connection is established and the base station is not currently the most suitable base station for establishing the connection.

The embodiment of the present invention comprehensively considers factors such as channel signal-to-noise ratio, base station computing resources, and user QoS when establishing a connection between an industrial Internet-oriented terminal device and a base station in a 5G communication network. Compared with the current technical solution, it can make full use of network resources and improve user service quality.

Exemplarily, as shown in FIG. 4 , it shows a specific time sequence in which the mobile terminal requests data. When the mobile terminal enters the overlapping coverage area of multiple base stations, the terminal detection module finds multiple base stations, and then sends a connection initialization request to the multiple base stations respectively, and the message of the connection initialization request carries the location information of the mobile terminal and the data to be calculated Quantity information, etc., as shown in step 1 in Figure 4. After base station 1 receives the connection initialization request message, the corresponding module is activated, and combined with the resources of its own MEC server, it calculates indicators such as "return time", as shown in step 2 in Figure 4. Secondly, the base station returns the calculation result to the mobile terminal, as shown in step 3 in FIG. 4 . For different base stations, the mobile terminal repeats the above steps 1-3, and finally obtains the information of all base stations in the area. Finally, the mobile terminal scores each base station according to the returned data, maintains a list of base stations locally, and selects the base station with the highest score to establish a communication connection with it, as shown in step 4 in Figure 4 . At the same time, the mobile terminal sends a communication connection establishment request to the optimal base station, as shown in step 5 in FIG. 4 .

The embodiment of the present invention discloses a method for selecting a base station by an industrial Internet terminal device in a next-generation communication network system, which belongs to the technical field of future networks.

An embodiment of the present invention provides a method for selecting a base station based on edge computing for the industrial Internet in a 5G communication network system. By sending data such as load information, location information, and requested QoS of the terminal to the MEC server of the base station, the base station can more accurately obtain the needs of the terminal. Then according to its own capabilities (such as computing memory size, server storage resources), analyze and calculate various technical indicators that can be provided to the terminal. After the mobile terminal acquires the data covering the base stations, it chooses the most suitable base station and establishes a communication connection. In this way, the goal of optimizing network resources and improving user service quality is achieved.

Compared with the existing technology, the embodiment of the present invention can comprehensively consider the channel signal-to-noise ratio, base station computing resources, user QoS, and mobile terminal standby time when establishing a connection between an industrial Internet-oriented terminal device and a base station in a 5G communication network.
