In this case, the service control apparatus 10 provides routing information of the corresponding agent to the switching device from among the agent group to which the short-range incoming service is registered in which the service type and the plurality of destination agent locations are registered in advance. Therefore, the intelligent network service exchanger 20 transmits an outgoing signal to the representative agent by using the information provided by the service control device 10. Accordingly, the representative agent receiving the outgoing signal performs voice or data communication with the fixed terminal. Subsequently, the representative agent finds the subagent closest to the wired terminal that requested the call out of the plurality of subagents that can communicate wirelessly and performs wireless communication when necessary.

However, since such a conventional technology is developed and developed based on a wired network, communication between a user and a representative agent is a wired network, and communication between a representative agent and a plurality of sub-agents is performed using a separate wired or wireless communication network. Both wired and wireless networks are required.

In addition, in order to find the location of the subagent closest to the wired terminal user who wants to contact urgently, wireless communication may be performed between the representative agent and each subagent.

SUMMARY OF THE INVENTION An object of the present invention has been made in view of the above-mentioned problems of the prior art. When an arbitrary terminal requests a wide area short-range incoming service in a cellular / PCS communication network that is currently expanding, a home location register The present invention provides a method for operating a wide-range short-range incoming service in a mobile communication system capable of connecting a call after searching for a called mobile agent located in a location closest to a calling terminal.

According to an aspect of the present invention for achieving the above object, in the mobile communication system, a method for operating a short-range short-range incoming service is to know the location and routing information of the current mobile agent group when calling a destination mobile agent from any terminal; And the step of connecting the call with the mobile agent closest to the terminal using the obtained information.
