Embodiment Construction

[0023] The present invention will be described in further detail below with reference to the accompanying drawings.

[0024] For the two state machines mentioned above, the advantage of the serial processor is that the order of the operating states is clear, but because the operating states have a strict order relationship, the asynchronous operations will be ordered, so that simultaneous operations can be performed. Asynchronous operations become operations that must be performed sequentially, so using a serial state machine to control asynchronous operations results in inefficient use of system resources. The use of parallel state machines to control asynchronous operations can precisely issue multiple non-causal operation requests at the same time, so that these non-causal operations can be performed at the same time, thus saving operation time and improving system resource utilization efficiency. However, when a parallel state machine is used to control asynchronous operat...

Abstract

The invention discloses a method of using state device to control asynchronous operation, according to the complexity and causality of asynchronous operation of a service, decomposing a service process flow into at least above two steps and at least a time sequence segment, configuring corresponding state device for each operating course of each step, where a bottom-layer state device jumps and then feeds state jump result back to a top-layer state device, the top-layer state device makes state jumping according to the state jump result of the bottom-layer state device in a time sequence segment until all the asynchronous operations of the service is completed. It makes the states in the whole service processing course fewer and the control course clear, therefore it has higher control efficiency of asynchronous operation and makes the written program by it easy to maintain and extend.

Description

technical field [0001] The present invention relates to an operation control method in a communication network or a computer network, in particular to a method for controlling a plurality of asynchronous operations with a state machine. Background technique [0002] In a communication network or a computer network, the control of multiple asynchronous operations is often involved. For example, a media gateway in a communication network involves the processing of many call services, such as establishing or dismantling a call resource path, in a certain Play audio, receive numbers or detect dual-tone multi-frequency (DTMF) on the call resource channel. These call processes involve numerous operations, such as applying for a channel, configuring the underlying data forwarding table, etc. These operations are asynchronous, that is, a message sending and receiving mechanism is required between the business processing module and the specific operation driving module. For these as...
