Abstract

The present invention is a method and system, with the system comprising an CPNS server and an end-point terminal for connecting the end-point terminal to a plurality of mobile communication terminals for providing the end-point terminal with a variety of services in a CPNS environment. The CPNS server makes a request for a CPNS service via a second mobile communication terminal, analyzes the request as transmitted to provide the end terminal with the service. The end-point terminal is connected to the first mobile communication terminal through a short-range wireless communication network for performing the CPNS service and is connected to a second mobile communication terminal through short-range wireless communication during the performance of the CPNS server to request and receive specific CPNS service from the CPNS server. Since the end-point terminal is connected to a plurality of mobile communication terminals and provided with CPNS services, the end-point terminal can simultaneously provide a variety of services.
