Description
Technical Field
The invention belongs to the technical field of mobile networks, and particularly relates to a multi-line dynamic optimization method and a multi-line dynamic optimization system for a terminal mobile network.
Background
At present, most terminal apps need to be connected with a server through a network, but due to the complicated network conditions of cities of various countries around the world, software developers can not deploy the server in each country/city. A typical software developer centrally deploys servers, such as silicon valley in the united states, in conjunction with the CDN, to ensure that users can access the silicon valley servers in every country/city. And at the moment, the connection from the user terminal to the developer server is that the user terminal < - > is a local CDN server < - > and the developer global server.
Some strong software developers may deploy servers in major data centers around the world (e.g., silicon valley, middle part of europe, tokyo of asia, saint paul of south america), and then cooperate with the CDN to connect users to nearby servers. At the moment, the connection between the user terminal and the developer server is that the user terminal < - > is a local CDN server < - > and the developer is a nearby city server.
Many times, for content that the CDN can statically cache: such as web pages/pictures/sound/video, this approach is very effective because most users can get the content on the CDN. However, for some dynamic contents which cannot be statically cached, each interaction between the user terminal and the developer server is a complete end-to-end interaction.
In the localization and complexity of the CDN providers, a software developer must select different CDN providers for different countries/cities, and the selection rule is to select a CDN provider with a higher ranking for the country city. However, even if the former CDN providers are selected for a country, it cannot be guaranteed that the providers rank the same in quality in each city and can connect to the CDN providers on a national scale because the connection quality of the CDN providers is a dynamically changing situation, which is related to regions, time, and scenes.

The first embodiment is as follows:
a multi-line dynamic optimization method of a terminal mobile network, referring to fig. 1, includes the following steps:
s1: a plurality of access lines and the long-term quality and the medium-term quality of each access line are built in the terminal; the access line is selected from a line table preset on the server;
the access lines comprise global access lines, national access lines and/or urban access lines, and the reliability of the global access lines, the national access lines and/or the urban access lines is greater than a preset value; the long-term quality is the average quality of the access line in the industry; the interim quality is an average quality of the access line over a period of time.
Specifically, selecting an access line is selecting a CDN provider. Since it is not possible to predict from which country or city the user of the terminal application is, in order to ensure the accessibility of the terminal, a highly reliable access line is first built into the user terminal.
The route table preset on the server includes access routes with high reliability on a global scale, see table 1.
Table 1:
| access line | Long term quality | Short term quality |
| akamai | 100.0 | 50.0 |
| cloudfront | 80.0 | 50.0 |
| cloudflare | 60.0 | 50.0 |
The long-term quality represents the average quality ranking coefficient of the access line in the industry, and can be represented in a 100-score mode, and data is derived from CDN evaluation websites around the open world. The medium-term quality represents the overall quality of the access line over a period of time (typically within 1 day) in the entire terminal application range, and can be represented by a 100-point system, and the medium-term quality can be uniformly initialized to 50 at the beginning. After the operation for a period of time, the medium-term quality can be corrected and updated according to the data uploaded by the terminal.
The route table on the server may also refer to CDN evaluation websites of some countries, including country-wide access routes ranked top, so that when a terminal connects to a network, the network of the country where the terminal is located may be preferentially connected, see table 2.
Table 2:
| access line | State of the country | Long term quality | Middle term quality |
| CDN77 | USA | 100.0 | 50.0 |
| KeyCDN | USA | 90.0 | 50.0 |
| Azure | USA | 70.0 | 50.0 |
| Aliyun (Aliyun) | China | 100.0 | 50.0 |
| Tengcong cloud | China | 85.0 | 50.0 |
| Huashi cloud | China | 80.0 | 50.0 |
In order to ensure that the user uses the access line at the city level, the line table on the server may also add city information to the access line, so that the line table obtained on the server is shown in table 3.
Table 3:
| access line | State of the country | City | Long term quality | Middle term quality |
| akamai | 100.0 | 50.0 | ||
| cloudfront | 80.0 | 50.0 | ||
| cloudflare | 60.0 | 50.0 | ||
| CDN77 | USA | 100.0 | 50.0 | |
| KeyCDN | USA | 90.0 | 50.0 | |
| Azure | USA | 70.0 | 50.0 | |
| Aliyun (Amiyun) | China | 100.0 | 50.0 | |
| Tengcong cloud | China | 85.0 | 50.0 | |
| Huashi cloud | China | 80.0 | 50.0 |
At the beginning, the data in the line list is insufficient and cannot cover all countries and all cities, but when the method is operated for a period of time, the line list can be slowly improved.
S2: when a terminal is connected with a network (including that the terminal application needs to be connected with the network after being started or needs to be reconnected after the current network of the terminal application is disconnected), evaluating built-in access lines according to a preset evaluation algorithm to obtain the quality of each access line, arranging the access lines according to the quality to form a connection sequence table, and starting connection from the access line with the optimal quality in the connection sequence table until the terminal is connected with a previous access line;
specifically, the terminal of the method selects the optimal access line comprehensively according to the existing access line, the corresponding long-term quality and medium-term quality, and the quality condition of each access line recently of the terminal.
Preferably, the evaluating the built-in access lines according to a preset evaluation algorithm to obtain the quality of each access line, and forming the access lines into a connection sequence table according to quality arrangement specifically includes:
the terminal acquires a currently available access line, and calculates a first line score of the access line by using the following formula;
the first line score is (long-term weight × long-term quality + medium-term weight × medium-term quality + short-term weight × short-term quality) × regional weight;
wherein the long-term weight, the medium-term weight, the short-term weight and the regional weight are set values; for example, the long term weight is 10, the medium term weight is 30, and the short term weight is 60, and if the access line is an urban access line, the regional weight is 3; if the access line is a national access line, the regional weight is 2; if the access line is a global access line, the regional weight is 1. The short-term quality is the average quality of the access line in a preset latest running period; the currently available access lines comprise the remaining access lines in the terminal after the access lines which are not connected recently are removed;
and arranging the access lines from high to low according to a first line score to form the connection sequence table, wherein the higher the first line score is, the better the quality of the access lines is.
Specifically, it is assumed that the access line built in the terminal is referred to table 4.
Table 4:
| access line | State of the country | City | Long term quality | Middle term quality | Short term quality |
| akamai | 100.0 | 50.0 | 50.0 | ||
| cloudfront | 80.0 | 50.0 | 50.0 | ||
| cloudflare | 60.0 | 50.0 | 50.0 | ||
| Aliyun (Aliyun) | China | 100.0 | 50.0 | 50.0 | |
| ... |
In table 4, the short-term quality represents the total quality of the access line during the last operation period (typically 1 hour), and the short-term quality can be uniformly initialized to 50 at the beginning. The short-term quality may be obtained by summing the scores of the last hour, with 0.0 being less than 0.0 and 100.0 being greater than 100.0. For example, access line 1 generated a +3 point record during the timing quality test, and access line 1 also had the following points in 1 hour: +5, -3, +2, +5, +2, +3, -1 then the short-term quality of access line 1 is equal to the sum of the above-mentioned fractions. When the method is operated for a period of time, the access line in the terminal is updated, see table 5.
Table 5:
| access line | State of the country | City | Long term quality | Short term quality | Short term quality |
| cloudfront | 80.0 | 60.0 | 32.0 | ||
| Aliyun (Aliyun) | China | 100.0 | 82.0 | 62.0 | |
| Tengcong cloud | China | 85.0 | 75.0 | 83.0 | |
| Baidu cloud | China | Guangzhou province | 85.0 | 68.0 | 77.0 |
| Huashi cloud | China | Guangzhou province | 80.0 | 57.0 | 89.0 |
| Mountain clouds | China | Guangzhou province | 100.0 | 72.0 | 38.0 |
It can be seen that table 5 contains 3 city access lines, 2 country access lines, 1 global access line. When the terminal is connected with the access line, the access line with the highest score of the first line is connected firstly, if the terminal is connected with the access line, the score of the access line is recorded as +5.0 scores, and meanwhile, the short-term quality of the access line is updated. If not, recording the score of the access line as-5.0 scores, and simultaneously updating the short-term quality of the access line to define the access line as the access line which is not connected recently. And then repeating the steps to connect the access lines with the first line scores.
S3: when detecting that the terminal is connected to the network, the server issues a plurality of access lines to the terminal according to the country or city where the terminal is located, and the method specifically includes:
the server searches the line table according to cities and countries in sequence, and sequentially sends a plurality of city access lines, country access lines and/or global access lines with the highest second line score in the line table to the terminal;
wherein the urban second line score is long-term weight multiplied by long-term quality + medium-term weight multiplied by medium-term quality; the city access line, the country access line and the global access line are different. The long term weight is 10 and the medium term weight is 30.
Specifically, the server may send down the line when the terminal first connects to the network each day. In the method, the server queries an IP database according to the IP address accessed by the terminal application and determines the country or city where the terminal is located. When the server issues the access lines, the server first issues city access lines, for example, according to a city lookup line table, the first 3 city access lines with the best score of the second line are searched, and if the first access lines are found, the found access lines are stored in a line result. And secondly, issuing a national access line, finding the first (5-the number of line results) national access lines with the best score of the second line in the line according to a national lookup line table, wherein the national access lines cannot be repeated with the access lines in the line results, for example, the line results comprise 'Aliyun', the 'Aliyun' cannot be selected at the moment, and if the national access line is found, the found access line is stored in the line results. And finally, issuing global access lines, searching the line table, finding the first (6-line result number) access lines with the best second line score in the line table, and storing the found access lines into the line result, wherein the access lines cannot be repeated with the access lines in the line result. And the server sends the line result to the terminal.
Typically, the access lines in the line result include 3 city access lines, 2 country access lines, and 1 global access line. If there are insufficient city access lines, the access lines include 5 national access lines and 1 global access line. If there are insufficient national access lines, the return line includes 6 global access lines. See table 6 for example for the line results issued.
Table 6:
in conclusion, the method is characterized in that access lines with high reliability are built in the terminal in a global range, the optimal access line is estimated according to the quality of each access line for the terminal to connect, and finally the server issues the corresponding access line to the terminal according to the geographic position of the terminal, so that the user terminal can be ensured to connect with the line with the optimal quality, and the global accessibility of a network is ensured.
Example two:
example two on the basis of the above example, the following contents are added:
after the terminal is connected with an access line, the method also comprises the following steps:
when detecting that the preset test time is up, the terminal is connected with all built-in access lines at the same time;
and updating the short-term quality of each access line according to the connection time of each access line.
Specifically, the terminal of the method can also perform connection test on the existing access line periodically, and evaluate, correct and update the short-term quality of the access line according to the test result. For example, all access lines are connected simultaneously every 5 minutes, ordered from fast to slow in connection time: the score of the 1 st access line is recorded as +3.0 points, the score of the 2 nd access line is recorded as +2.0 points, and the score of the access line after the 3 rd access line is recorded as +1.0 points. For an access line with no connection, the score of the access line is recorded as-3.0.
Preferably, after the server issues a plurality of access lines to the terminal according to the country or city where the terminal is located, the method further includes:
when detecting that the preset updating time is up, the terminal sends the short-term quality of each access line to the server;
and the server corrects the corresponding medium-term quality according to the short-term quality of each access line.
Specifically, the update time may be set to 1 time per day. The terminal sends the short-term quality of all access lines to the server. The server firstly groups all access lines according to the line + country + city, calculates the medium-term quality of each city group, the medium-term quality is the sum of all short-term qualities in the group/the number of data in the group, the updated line table of the server refers to table 7, if the original line table has the updated access line, the updated access line is directly updated; otherwise, a record is created.
Table 7:
| access line | State of the country | City | Middle term quality |
| Aliyun (Aliyun) | China | Shenzhen (Shenzhen medicine) | 62.0 |
The server then groups all the access lines according to the line + country, calculates the medium-term quality of each country group, the medium-term quality is the sum of all the short-term qualities in the group/the number of data pieces in the group, and the updated line table of the server refers to table 8.
Table 8:
| access line | State of the country | City | Middle term quality |
| Aliyun (Aliyun) | China | 73.0 |
The server finally groups all the access lines according to the lines, calculates the medium-term quality of each global group, the medium-term quality is the sum of all the short-term qualities in the group/the number of data strips in the group, and the updated line table of the server refers to the table 9.
