Abstract: In an application cooperation apparatus for supporting configuration/reconfiguration of a business process support system, node class object information defining a logical AP object as an object class for each common process item and attribute and defining an inheritance relationship between object classes as a tree structure is provided to define interactively with a user a logical process model having logical AP objects as business components. Next, by referring to logical-physical object correspondence relationship information, an implementation process model for the logical process model is developed to generate execution control scripts in a definition language of this model.

Abstract: A public key cryptosystem is used for the authentication of a personal station (PS) which subscribes for a plurality of radio communication exchange systems. A public key of PS is registered into a public key DB of a public key management device. A private key is registered into PS. When PS moves into a service area of a certain radio communication exchange system, an exchange in that radio communication exchange system requests the public key management device for a public key of PS and makes a check for authentication of PS based on the public key cryptosystem by use of the received public key. Thereafter, when PS moves into a service area of another radio communication exchange system, an exchange in the other radio communication exchange system similarly requests the public key management device for a public key of PS and receives the same public key.

Abstract: In a mobile radio communication system of a multi-layer cell structure for covering service areas in layers with cells of different sizes, an enquiry originating mobile terminal transmits enquiry information in an enquiry frame to the N-th layer exchange through the N-th layer base station. The exchange discriminates a kind of the enquiry frame at processing, selects at processing, a minimum cell for covering a distribution area or a minimum number of cells which can cover the distribution area from the state of geographical distribution of the enquiry destinations, fills the numbers of the base stations for forming these cells and the numbers of the exchanges for covering these base stations in the enquiry frame, and transmits this enquiry frame to the corresponding exchange. The exchange checks the numbers of the base stations of the enquiry frame and transmits the enquiry frame to the corresponding base stations.
