Detailed ways

In order for those skilled in the art to better understand the technical solution of the present disclosure, the waiting time determination method, server and computer-readable medium provided by the present disclosure will be described in detail below with reference to the accompanying drawings.

The method for determining the waiting time provided in the present disclosure can be used to set the waiting time for each registered terminal to send the IP multimedia system registration request again according to the user priority.

The waiting time determination method can be applied to the information system (IOM) side. Specifically, when the user terminal supports the long-term evolution voice bearer function and turns on the corresponding switch, a reverse subscription will be triggered. If the first registration is enabled or the registration fails, the network side will send a message with a waiting time to the user terminal while signing the contract. Registration failure message, the user terminal registers again after a waiting time to complete the opening of the service function.

Among them, on the network side, after receiving the registration request sent by the user terminal, the home subscriber server (Home Subscriber Server, HSS) will initiate a call to the corresponding service of the front-end processor of the information system, and report to the first registration activation or registration failure The user terminal sends a registration failure message. Because in the existing solution, the waiting time attached to the registration failure message is the default time, such as 5 minutes, all user terminals that need to resend the registration request are sent after the default time. When there are many registration requests at the same time, it will cause After the corresponding default time, there are many repeated registration requests, forming message congestion between the application server (Application Server, referred to as AS) and the information system, accumulating a large amount of request information, which brings a large burden to the network side, and at the same time cannot effectively To register and open.

Fig. 1 is a flowchart of a method for determining a waiting time provided by an embodiment of the present disclosure. As shown in Figure 1, it can be applied to the information system side, and the method includes:

Step S1. Obtain the user priority corresponding to each newly arrived registered terminal.

In step S1, the user priority can be automatically generated on the network side using the corresponding rule algorithm. Specifically, it can be obtained according to the user package information, user membership level, registration time and repeated registration times, etc., and can also be manually set. Generally, User priority can be set directly according to user membership level.

In some embodiments, the user priority is obtained from the home subscriber server.

Step S2: Determine the waiting time for each registered terminal to resend an IP Multimedia System (IP Multimedia Subsystem, IMS for short) registration request according to the user priority.

Wherein, the registration terminal sends the IP multimedia system registration request, which means that the user terminal side opens the long-term evolution voice bearer function or subscribes to the long-term evolution voice bearer service, the registration terminal receives the waiting time, and sends the IP multimedia system registration request to the network side again after the waiting time .

In some embodiments, step S2, the step of determining the waiting time for each registered terminal to send the IP multimedia system registration request again according to the user priority, specifically includes:

For the first registered terminal whose user priority is less than the preset priority threshold, the following formula is used:

The waiting time corresponding to each first registered terminal is determined.

表示当前的负荷值；该公式体现为：该第一注册终端的注册位次和系统每秒处理请求数量相除并向下取整得到位次附加值，等待时间由位次附加值与当前的负荷值相加计算得到。由此可根据系统每秒处理请求数量和负荷值分批次地实现对大量注册请求的处理，满足系统负荷的同时最大限度使用处理能力，合理规划用户终端等待时间，减少阻塞现象，增加注册请求处理效率。Among them, T _iretry represents the corresponding waiting time when the first registered terminal is the newly arrived i-th registered terminal, M is the total number of registered terminals queued in the system, N is the number of requests processed by the system per second,

Indicates the current load value; the formula is expressed as: dividing the registration number of the first registered terminal by the number of requests processed by the system per second and rounding down to obtain the additional value of the ranking, and the waiting time is determined by the additional value of the ranking and the current Calculated by adding load values. In this way, a large number of registration requests can be processed in batches according to the number of requests processed by the system per second and the load value, to meet the system load and maximize the use of processing capacity, reasonably plan the waiting time of user terminals, reduce blocking phenomena, and increase registration requests Processing efficiency.

In some embodiments, for the second registered terminal whose user priority is greater than or equal to the priority threshold, when the load value is less than or equal to the preset load threshold, the waiting time of each second registered terminal is set within the default waiting interval .

Specifically, when it is determined that the current load value is relatively small, the waiting time of all second registered terminals can be directly set within the default waiting interval, and the right endpoint value of the default waiting interval is relatively small, such as 1 minute, so as to achieve When it is small, the waiting time for sending the corresponding registration request is reduced, and the request processing efficiency is increased. In addition, the waiting time of each second registered terminal can be selected in a random or sequential manner according to specific circumstances within the default waiting interval.

In some embodiments, for the second registered terminal, when the load value is greater than the preset load threshold, based on the preset first correspondence table, the corresponding waiting interval is determined according to the user priority of each second registered terminal; Wherein, the first correspondence table records different user priorities and corresponding waiting intervals.

Specifically, the higher the user preference level, the smaller the left endpoint value of the waiting interval. Generally, for the convenience of value selection and verification, each interval can take the same length, for example, one interval per minute.

In some embodiments, for the second registered terminal, when the load value is greater than the preset load threshold, the corresponding waiting time is determined according to the user priority of each second registered terminal; wherein, the second correspondence table records Different user preferences and their corresponding waiting times.

Specifically, the higher the user preference level, the shorter the corresponding waiting time. Generally, for the convenience of value selection and verification, the waiting time corresponding to each user priority level can be taken at the same time interval. For example, each user The waiting time corresponding to the priority level is one minute apart.

The embodiment of the present disclosure provides a waiting time determination method, which can be used to set the waiting time for each registered terminal to send the IP multimedia system registration request again according to the user priority, and also consider the registration time and network congestion when determining the waiting time, While ensuring the timeliness and success rate of specific user registration, it improves the overall efficiency of registration request processing, improves the efficiency of service registration activation, and reduces the network burden.

Fig. 2 is a flow chart of another method for determining a waiting time provided by an embodiment of the present disclosure. As shown in FIG. 2 , the method is a practical alternative implementation based on the method shown in FIG. 1 . Specifically, after step S2, further include: step S3.

Step S3, sending the determination result of the waiting time of each registered terminal to an interrogating session call control function entity (Interrogating Call Session Control Function, ICSCF for short).

In step S3, the determination result of the waiting time of each registered terminal is sent to the query session call control function entity, for the query session call control function entity to respond to the registration failure message sent to each registration terminal according to the determination result The first Retry-After is set. Wherein, the registration failure message is a 404 response message, or a registration "404 Not Found" response.

The method for determining the waiting time provided by the present disclosure will be described in detail below in combination with practical applications. Specifically, it includes the user terminal side and the network side, the user terminal side corresponds to the registered terminal, and the network side includes the home subscriber server, the Mobility Management Entity (MME for short), the information system, and the inquiry session call control function entity , full service platform and base station subsystem.

The registered terminal performs the first registration and activation of the long-term evolution voice bearer service. After completing the pre-embedding of the IP multimedia system access point (APN), it sends an IP multimedia system registration request to the home subscriber server through the mobility management entity, and accesses the IP multimedia system System Data Network (PDN).

After receiving the registration request, the home subscriber server invokes the corresponding service of the front-end processor of the information system, and sends the user priority of the registered terminal to the information system; the information system sends the registration request to the full-service platform, according to The user priority determines the waiting time for each registered terminal to resend the registration request, and sends the determined waiting time to the query session call control function entity. For the specific determination process, refer to the above-mentioned embodiment. Thereafter, a registration failure message is sent to the registered terminal via the inquiry session call control function entity, mobility management entity and base station.

After receiving the registration request, the full-service platform determines and sends the registration request to the base station subsystem corresponding to the registration terminal according to the corresponding user information, performs forward provisioning of the long-term evolution voice bearer service, and sends the subscription service to the home subscriber after the provisioning is completed. The server returns a response. Thereafter, the registration terminal can receive the registration success message by sending the IP multimedia system registration request again after the waiting time, and thus completes the registration and provisioning of the long-term evolution voice bearer service of the registration terminal.
