Embodiment Construction

[0009] Referring to Figure 1, under the UML tool, in order to realize the synchronization of call status data between the active and standby modules, the following two parts are included:

[0010] (1) In the main processing module 101, for any call, the value records of the internal attributes corresponding to the current states are saved in the object instance processing the call, and these information are synchronized to the corresponding standby module .

[0011] (2) When the main processing module 101 fails, as shown by the arrow 102, the calls made from this module 101 will be moved to the corresponding standby module 103 for processing. At this moment, the standby module 103 receives a message, and is informed that the active module has broken down, so that the standby module is set as a new active processing module and performs call processing; As shown in block 106, first obtain the object instance and corresponding information for processing the call, that is, the va...

Abstract

Objects in a class for processing specific calling flow are defined by using UML tool. Corresponding state information is change through changing internal attribute values of the object. In main processing module for protocol calling, internal attribute values in object instance of processing the calling flow are recorded for any calling, and recorded values are synchronized to corresponding spare module. When fault happens in main module, the callings in the main processing module are transferred to spare module, or the spare module becomes new main module. In the new main module, internal attribute values recorded in step are read out to replace corresponding internal attribute values in instance of the object for any calling. Thus, synchronization of state data between main module and spare module is realized.

Description

technical field [0001] The invention belongs to the field of communication equipment manufacturing, and specifically relates to a method for realizing synchronization of call state data between active and standby modules by using UML tools. Background technique [0002] The Unified Modeling Language (UML for short) is an intuitive, explicit, and visual general-purpose modeling language, initiated by world-renowned object-oriented technology experts Grady Booch, Jim Rumbaugh and Ivar Jacobson, in the OMT (Object-oriented Modeling Technology , object-oriented modeling technology) method and OOSE (Object-Oriented Software Engineering, object-oriented software engineering) method developed on the basis of. In fact, UML tools (such as Rhapsody, Rational Rose) integrate analysis, design and development and are a powerful tool. In UML tools, a state diagram is a very important model diagram that can be used to describe all possible states of a class of objects and the conditions r...
