Abstract

PURPOSE:To provide a virtual protocol control system in which difference in protocols is concealed in the system accommodating plural protocols. CONSTITUTION:A virtual protocol control section 13 is provided between a protocol control section 12 and a basic call control section 14 and the virtual protocol control section 13 normalizes a protocol from the protocol control section 12. The virtual protocol control section 13 selects normalization information from normalized information registered in a form by which an event and a state are selected in the virtual protocol control section and normalizes the protocol based on the normalizing information to make a processing request to a basic call control section 14. Thus, the difference from protocols is concealed and the development of the additional service is facilitated.

2. Description of the Related Art Conventionally, in this type of system, a common primitive has only been defined as a common interface for hiding the difference between primitives for each protocol in the basic call control layer. It had no means of normalizing the differences. Therefore, in order to provide the same supplementary service for different protocols, it was necessary to prepare the supplementary service for each protocol. Moreover, when changing the content of the additional service, it was necessary to change the processing content throughout the system. A system that solves this problem is proposed in Japanese Patent Laid-Open No. 2-48891. In this system, an execution condition data storage means for storing the execution condition of the service in the additional service control unit, and a service execution analysis means for searching the execution condition data corresponding to the requested service and accessing the service execution means. This makes it easy to change or add the contents of additional services.

In the conventional system,
The difference in the procedure for each protocol is not hidden from the basic call control layer, and when showing the procedure in the basic call control layer, not only the protocol needs to be noted but the additional service is provided. When doing so, it is necessary to be aware of the protocol, and there is a drawback that it is difficult to develop an increasing number of additional service software.
