Detailed ways

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

FIG. 1 is a schematic block diagram of a system framework 100 provided by an embodiment of the present application.

As shown in FIG. 1 , the system framework 100 may include the Internet 110, servers 121-125, and users 131-135. The Internet 110 can provide various application services to the users 131-135 through the servers 121-125. Internet 110 may include servers provided by Internet vendors. The servers 121 to 125 may be servers of respective operators. Illustratively, taking the application as an example of products such as cloud conferencing provided by Internet manufacturers, the Internet 110 may provide products such as cloud conferencing to users 131 - 135 through servers 121 - 125 . For example, the Internet 110 may provide various application services to the user 131 through the servers 121-123. For another example, the Internet 110 may provide various application services to the user 132 through the server 123 . For another example, the Internet 110 may provide various application services to the user 133 through the servers 123-124. For another example, the Internet 110 may provide various application services to the user 134 through the server 124 . For another example, the Internet 110 may provide various application services to the user 135 through the server 125 .

For example, the Internet 110 may provide audio and video conference services to the users 131-135 through the servers 121-125. In other words, the audio and video conferencing service can be understood as an online multi-person conversation activity carried out by means of Internet 110 facilities using multimedia data such as voice and video as a carrier.

It should be understood that FIG. 1 is only an example of the present application, and should not be construed as a limitation of the present application.

For example, in some embodiments of the present application, the system framework 100 may further include multiple access points. Based on this, the users 131 to 135 may use the access points to access the servers 121 to 125 based on their own terminals. The corresponding server is used to convert public network data transmission into private line data transmission, thereby reducing data delay and packet loss, and further ensuring the signal transmission quality on the user side as much as possible. For example, the access point may be the first service server that the user connects to. However, given the cost and the distribution of the operator's room infrastructure, access points can only be established in a limited number of cities. Based on this, the distribution center needs to schedule appropriate access points for users according to a certain scheduling policy, and the access point distribution policy will directly affect the end-to-end service quality.

As shown in FIG. 2 , the system framework 200 may include: a client 210 , a distribution server 220 , a statistics server 230 and a database 240 . It should be noted that the function of the statistics server 230 or the function of the database 240 may be integrated into the distribution server 220 .

The client (Client) 210 may also be called a workstation (Workstation). For example, a computer connected to a network can control and manage the client 210 through a network server, so that the client 210 can share various resources on the network. For example, the web server may be the servers 121 to 125 shown in FIG. 1 .

The distribution server 220 may be integrated with any apparatus for scheduling access points provided in the embodiments of the present application, and is configured to execute the method for scheduling access points provided in the embodiments of the present application. For example, the distribution server 220 may be configured to collect the indicators used to characterize the access quality of all the access points in the preset set by the mobile terminal, and determine the optimal access point list according to the indicators used to characterize the access quality, and then The access points of the mobile terminal are scheduled based on the optimal access point list.

In addition, the client 210 may schedule the target access point to be accessed through the distribution server 220 . For example, a request message can be sent to the distribution server 220, wherein the request message carries the IP address of the client 210, and then the distribution server 220 queries the optimal access point list according to the IP address of the client 210 to obtain the optimal access point list. Schedule access points, and schedule the access points of the client 210 based on the optimally scheduled access points, that is, the client 210 can access the network server through the optimally scheduled access points, such as sending an access request to web server, etc. It should be understood that when the distribution server 220 schedules the access points of the client 210, it can also be understood that the distribution server 220 schedules the access points of the users, and it can also be understood that the distribution server 220 schedules the access points of the terminals corresponding to the users. Schedule.

The database (Database) 240 can be regarded as an electronic filing cabinet. As a place for storing electronic files, users can perform operations such as adding, querying, updating, and deleting data in the files. The database 240 may include collections of data that are stored together in a manner that can be shared with multiple users, have as little redundancy as possible, and are independent of applications.

The database (Database) 240 may also be understood as a database management system (Database Management System, DBMS). DBMS can be understood as a computer software system designed for database management, which generally has basic functions such as storage, interception, security assurance, and backup. A database management system can be classified according to the database model it supports, such as relational, Extensible Markup Language (XML); or according to the type of computer it supports, such as server clusters, mobile phones; or Classification according to the query language used, such as Structured Query Language (SQL), XQuery; or classification according to the focus of performance impulse, such as maximum scale, maximum running speed; or other classification methods. Regardless of the classification method used, some DBMSs are capable of cross-classification, for example, simultaneously supporting multiple query languages.

Of course, the information sent by the client 210 may also be stored in the database 210 in a cloud storage manner.

Cloud Storage is a new concept extended and developed from the concept of cloud computing. Distributed cloud storage system (hereinafter referred to as storage system) refers to functions such as cluster application, grid technology and distributed storage file system. A storage system that integrates a large number of different types of storage devices (also called storage nodes) in the network through application software or application interfaces to work together to provide external data storage and service access functions.

For example, the storage method of the storage system is to create a logical volume, and when the logical volume is created, a physical storage space is allocated to each logical volume, and the physical storage space may be composed of the disks of a certain storage device or several storage devices. The client stores data on a logical volume, that is, the data is stored on the file system. The file system divides the data into many parts, each part is an object, and the object contains not only data but also data identification (ID, ID entity) and other additional information, the file system writes each object into the physical storage space of the logical volume, and the file system records the storage location information of each object, so that when the client requests to access data, the file system can The storage location information of the object allows the client to access the data.

The process of allocating physical storage space by the storage system to the logical volume, specifically: according to the capacity estimation of the objects stored in the logical volume (this estimation often has a large margin relative to the actual capacity of the objects to be stored) and independent redundant disks Array (RAID, Redundant Array of Independent Disk) group, which divides the physical storage space into strips in advance, and a logical volume can be understood as a stripe, thereby allocating physical storage space for the logical volume.

In some embodiments of the present application, the statistics server 230 may be configured to obtain statistical data from the database 240 and process the statistical data, and the processing result of the statistical data may be used to assist the distribution server 220 in scheduling the access point of the client 210 .

The statistics server 230 may be a physical server capable of performing computing processing, or may be a cloud device capable of performing computing processing.

For example, the distribution server 220 may have a device with cloud computing (Cloud Computing) function. Cloud computing is a computing mode that can distribute computing tasks on a resource pool composed of a large number of computers, so that various application systems can obtain computing power as required. , storage space and information services. The network that provides the resources may be referred to as the "cloud". The resources in the "cloud" are infinitely expandable in the eyes of users, and can be obtained at any time, used on demand, expanded at any time, and paid for according to usage. A cloud computing resource pool can be established through a cloud computing basic capability provider, and the cloud computing resource pool can also be called an Infrastructure as a Service (IaaS) platform. Various types of virtual resources can be deployed in the cloud computing resource pool for external customers to choose and use. In other words, the cloud computing resource pool may include: computing devices, storage devices, and network devices. Optionally, the computing devices in the cloud computing resource pool may be virtualization devices, for example, may include operating system virtualization devices.

SaaS can be deployed directly on IaaS. PaaS is a platform on which software runs, such as databases and web containers. SaaS is a variety of business software, such as web portals, SMS group senders, etc. Generally speaking, SaaS and PaaS are upper layers relative to IaaS.

In addition, the statistics server 230 may also acquire the results of the statistics data by means of big data.

Big data can be understood as a collection of data that cannot be captured, managed and processed by conventional software tools within a certain time frame. It is a massive, high-growth process that requires new processing modes to have stronger decision-making power, insight discovery power, and process optimization capabilities. rate and diversification of information assets.

FIG. 3 is a schematic block diagram of a method 300 for scheduling an access point provided by an embodiment of the present application. The method 300 may be executed by a server, and the embodiment of the present application is described by taking the server as an allocation server as an example. For example, the distribution server is the distribution server 220 shown in FIG. 2 .

As shown in FIG. 3, the method 300 may include:

The above S310, that is, determining at least one quality index between the terminal and at least one access point respectively, the quality index is used to represent the access quality expected by the terminal after accessing the corresponding access point, wherein each The quality indicator corresponds to the access quality between the terminal and an access point.

S320: The allocation server schedules the target access point to be accessed by the target user based on the at least one quality indicator, where the at least one quality indicator is used to represent the access quality of the target type of the target user relative to the at least one access point, respectively. At least one access point includes the target access point.

In the above S320, that is, based on the at least one quality indicator, the target access point is scheduled to the terminal from the at least one access point. Optionally, the at least one quality index may be at least one quality index value. Optionally, the at least one quality index belongs to the same type of index.

For example, the distribution server determines a user of the target type, and determines the access point corresponding to the user of the target type as the at least one access point, so as to obtain at least one quality indicator corresponding to the at least one access point, and then can be based on The at least one quality indicator determines the target access point. For example, the allocation server may determine an optimal access point list based on the at least one quality indicator, and may then schedule the target user's access points based on the optimal access point list.

Optionally, the distribution server determines the access point with the highest quality index as the target access point.

Optionally, the allocation server sorts each access point based on the quality index in descending order, selects the access point located at the top of the ranking and adds it to the list of optimal access points, and selects the access point from the optimal access point. An access point is randomly selected from the list as the target access point.

For example, the distribution server may perform summary statistics on the access indicators of the target type of users with respect to the at least one access point on a periodic basis (hours or days) to generate the at least one quality indicator.

By constructing the at least one quality indicator as the access quality of the user of the target type relative to the at least one access point; equivalently, using the user type as the granularity to quantify the access quality of the at least one access point, avoiding the use of The user is the granularity, and the access quality of each user relative to the at least one access point is quantified; on the one hand, it can not only simplify the division granularity of the at least one quality index to reduce the scheduling complexity and scheduling cost, but also can be a quality index Provide enough reference information to improve the accuracy of the at least one quality indicator, and further improve the end-to-end communication quality, correspondingly, it can improve user experience and user satisfaction; The network environment of the target user or the user environment of the target user is complex and changeable. Through at least one quality indicator corresponding to the user of the target type, the complex and changeable attributes of the network environment or the user environment can be reflected in real time, so as to further improve the end-to-end The communication quality of the terminal, correspondingly, further improves the user experience and user satisfaction.

To sum up, scheduling the target access point to be accessed by the target user based on the at least one quality index can improve the end-to-end communication quality while reducing the scheduling complexity and scheduling cost, and accordingly, the user experience and user satisfaction can be improved. Spend.

Especially, for high-traffic scenarios such as audio and video communication, it can improve the end-to-end communication quality while reducing the scheduling complexity and scheduling cost, and accordingly, improve user experience and user satisfaction.

In some embodiments of the present application, the target type includes at least one of a target area or a target operator. In one example, the target type includes only a target area, for example, the target area is accurate to a country, a province, a city, or , the target area is accurate to countries, provinces, cities, municipal districts, etc. The embodiment of this application does not specifically limit the division accuracy of the target area; in another example, the target type only includes the target operator, and the target operator refers to The operator to which the terminal corresponding to the user accesses, the number of target operators may be one or more, and the embodiment of this application does not specifically limit the number of target operators; in another example, the target type includes both the target area It also includes target operators, which can divide the types of terminals corresponding to users from more dimensions.

For example, the distribution server may be divided according to several dimensions of country, province, city, and operator, and collect statistics on the access indicators of the target type of users relative to the at least one access point to generate the at least one quality indicator.

In some embodiments of the present application, the target region includes regions divided by country, province or city.

The at least one quality index is exemplarily described below with reference to Table 1.

Table 1

As shown in Table 1, at least one quality index corresponding to at least one access point can be quantified with the user of the target type as the granularity. For example, the access qualities of the users in the first area to the first access point, the second access point, and the third access point are a1, b2, and c1, respectively. Of course, different types of users may also correspond to different access points. For example, the access qualities of the users of the first operator to the first access point and the third access point are a3 and c3. For another example, the access qualities of the users of the second operator relative to the first access point and the second access point are a4 and b4.

In some embodiments of the present application, the S310 may include:

determine the target type;

The above process means that the distribution server determines the target type corresponding to the terminal of the user; based on the mapping relationship information, determines at least one quality index corresponding to the target type, wherein the mapping relationship information includes at least one type of terminal respectively. A quality indicator with the at least one access point, the at least one type includes the target type. In this case, it is precisely because terminals of the same type have the same quality indicators for the same access point. Therefore, if you want to obtain various quality indicators of the terminal, you only need to determine the target type corresponding to the terminal, and query the Each quality index corresponding to the target type is sufficient, in other words, all terminals belonging to the target type use each quality index corresponding to the target type to perform access point scheduling.

For example, the distribution server may determine the target type based on the IP address of the target user, and then determine the at least one quality indicator based on the type of the target type and the mapping relationship information. It should be understood that the IP address of the target user can also be understood as the IP address of the client 210 shown in FIG. 2 .

In some embodiments of the present application, the allocation server receives a request message, where the request message is used to request to schedule an access point for the target user, in other words, the request message is used to schedule an access point for a terminal corresponding to the target user; Then, the distribution server may determine the target type based on the access information in the request message. As an example, the distribution server may receive the request message sent by the client 210 as shown in FIG. 1 . For example, the access information may include the target user's IP address so that the distribution server may determine the target type based on the target user's IP address.

In some embodiments, the mapping relationship information may be information generated based on feedback information of each user. The feedback information may include an indicator for feeding back the access quality of the access point serving the user, or the feedback information may include an indicator for feeding back the end-to-end communication quality.

It should also be understood that the embodiments of the present application do not limit the specific implementation manner of the mapping relationship information, for example, the mapping relationship information may be in the form of a table, or may be in other forms.

For example, the mapping relationship information is a quality index matrix, and the same row in the quality index matrix is used to represent the quality indexes of the same type of users in the at least one type of users with respect to the at least one access point, respectively. The same column is used to represent the quality indicators of the same access point in the at least one access point with respect to the at least one type of user respectively. That is to say, the same row in the quality indicator matrix is used to characterize the quality indicator between a terminal of the same type and the at least one access point, and the same column in the quality indicator matrix is used to characterize the same access point A quality indicator with the at least one type of terminal.

In some embodiments of the present application, the method 300 may further include:

Establish or update the mapping relationship information.

For example, the distribution server establishes or updates the mapping relationship information, and determines the at least one quality indicator based on the established or updated mapping relationship information.

In some embodiments of the present application, the S310 may include:

For example, the distribution server sends the query message to the statistics server, and receives a response message to the query message sent by the statistics server.

In other words, the statistics server may determine the at least one quality indicator based on the query message and the mapping relationship information. It should be noted that, the implementation manner of determining the at least one quality indicator by the statistics server may refer to the implementation manner of determining the at least one quality indicator by the distribution server, and details are not described here to avoid repetition.

For example, the statistics server receives the query message, determines the target type based on the access information in the query message, and then determines the at least one access point and the at least one access point based on the target type and the above-mentioned mapping relationship information corresponding at least one quality index, and then send a response message to the query message. Based on this, the statistics server can also be used to establish or update the above-mentioned mapping relationship information.

In some embodiments of the present application, each of the at least one quality index is an index determined based on at least one type of quality index.

In other words, each of the at least one quality index may be an index determined based on at least one type of quality index. For example, the at least one type of quality indicators may be one or more types of quality indicators fed back by users of the target type.

In some embodiments of the present application, each quality index in the at least one quality index is a quality index determined according to the following formula:

Wherein, Q _j represents the j-th quality index in the at least one quality index, X _i represents the i-th quality index in the at least one type of quality index, and _xi represents the i-th quality in the at least one type of quality index The weight corresponding to the indicator, m represents the number of types of the at least one type of quality indicator.

Certainly, the determination of each quality index in the at least one quality index by the weight of each type of quality index in the at least one type of quality index is only an example, which is not specifically limited in this application. For example, in other alternative embodiments, each quality index of the at least one quality index may be determined by a maximum value or a minimum value or the like.

In some embodiments of the present application, the at least one type of quality indicator includes at least one of the following indicators: sound quality, voice freeze, video clarity, video freeze, end-to-end delay, or quality of service (Quality of Service) , QoS), for example, for multi-person audio calls, the selected indicators include sound quality, voice freeze, end-to-end delay and QoS, and for multi-person video calls, the selected indicators include: sound quality, voice freeze, For video definition, video freeze, end-to-end delay, and QoS, the embodiment of the present application does not specifically limit which indicators are selected.
