Abstract: A method for performing a method call from an object in a client to an object in a server when communication protocols of distributed object middlewares in the client and in the server are different is provided. A remote reference obtaining relay object and a class of a remote method calling relay object are provided between the client and the server, and the method includes the steps of: the remote reference obtaining relay object receiving an obtaining request for a remote reference on the object in the server from the client, and sending the obtaining request to the server; the remote reference obtaining relay object receiving, from the server, information used for accessing the object in the server, instantiating the remote method calling relay object corresponding to the object, sending, to the client, information used for accessing the remote method calling relay object.

Abstract: The present invention discloses a communication system in a network system having a plurality of user terminals connected to a communication network and a plurality of network resources accessed by the user terminals, the communication system having a communication part which makes the user terminals accessing the same network resource exchange and share communication information. The communication part has a communication server and a communication controlling part, provided in each user terminal, for obtaining information of the user terminals accessing the same network resource and for exchanging the communication information with the user terminals through the communication server. The communication server groups the user terminals accessing the same network resource as one group on the basis of resource locators notified of by the user terminals, and distributes information of the user terminals of the one group to the user terminals of the one group.

Abstract: The purpose of the invention is to provide a radio-pager that allows a user to set any desired call-sign therein and method of radio-paging that not only conducts person-to-person communication but easily realizes transmission from one person to a plurality (N) of persons such as simultaneous transmission of the same message or commercial massage to a number of pagers. The pager receives radio waves by an antenna, demodulates the received signal into digital data by a radio demodulator and transfers the data to a digital circuit that corrects the data for code transmission error caused by affection of fading. A CPU of the pager examines the correctly reproduced data and extracts a call-sign from the data stream. The CPU 25 reads a call-sign stored in a RAM and examines whether the extracted call-sign corrsponds to the stored call-sign. The pager drives an electronic speaker when the CPU detects that both call-signs are identiacal with each other.
