Method and device used for providing timing function

Abstract

The invention aims to provide a technology of providing a timing function for a processing and data separation system. A cloud timer is newly introduced in the technology. The cloud timer at least comprises a first node and a second node. The first node is used for receiving a timer starting request from processing, wherein the timer starting request comprises a timer identifier, expiration time and a notifier identifier. The second node is used for sending a timer timeout notification to a network entity corresponding to the notifier identifier when the expiration time of the timer is up. Compared with the prior art, the technology has the advantages that a design principle of a Worker-State model is not destroyed, a starter of the timer can specify a notification object when the timer expires and information carried in the timer timeout notification, and the defects in the prior art are made up for. The design of the cloud timer adopts a multi-node redundant backup principle, which conforms to a basic thought of a cloud computing environment.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a technology for providing a timing function. Background technique [0002] In traditional applications where processing and data are not separated, timers are a local resource. Figure 1(a) shows a schematic diagram of a traditional application model. As shown in Figure 1(a), in traditional applications, timers are embedded into each application instance along with service logic and status information. Traditional applications have relatively poor elasticity, that is, it is difficult to change the size, location, etc. of the application. In a cloud computing environment, elasticity is a must-have feature for cloud applications. Without elasticity, applications will not be able to enjoy various advantages of the cloud computing environment. [0003] Currently, there is a solution to improve the flexibility of traditional applications, that is, to evolve the traditional ap...

Problems solved by technology

Obviously, the first type of cloud database cannot meet such demands

Although the second type of cloud database can send a data deletion notification message to the processing, the notification message is only used to inform the processing that the data has been deleted, and does not have any information about the data, which will result in incomplete data Used to notify the S-CSCF of the UE's registration timeout

[0016] 1) Reserving the timer on the processing side violates the design principle that processing is stateless in the Worker-State model, and in some cases, when the processing is completed, the resource cannot be completely released because the timer started by it is still running. Undoubtedly a waste of resources

[0017] 2) Due to the need to save and update the corresponding relationship between timers and processing in the cloud database, the complexity of the system is increased

[0018] 3) Due to the migration of the timer, the accuracy of the timer will be reduced

[0019] It can be seen that there is no technical solution in the prior art that can well solve the timer problem in the Worker-State model
