Abstract

The invention provides a wireless internal system and an internal base station. The PHS internal terminal of a PHS indoor coverage system is cut off from a common network when switching to the public CS during the internal communication. The overall calling sectional numbers 212 of the internal CS of the PHS indoor coverage system are set with a value which is different from the surrounding public CS. Each calling in the CSS is based on the called number from a terminal, the internal calling is determined if providing with an internal particular number or the external calling is determined, and then results are noticed to the base station side. The internal calling terminal of the base station sets the TCH switching function type of the TCH switching information factor of the functional reclaim responding information into a re-calling type connection function excluding other CS in the overall calling section, thereby preventing the PHS internal terminal in the internal communication from switching into the public CS.

Description

technical field [0001] The present invention relates to a wireless extension system and an extension base station, and relates to a wireless extension system and an extension base station which prevent a PHS extension terminal from switching to a surrounding PHS public base station (hereinafter referred to as a public CS) during an extension call and cut off the call. Background technique [0002] PHS (Personal phone System) indoor coverage system is an extension system using public radio frequency. The PHS indoor coverage system uses the PHS public terminal for internal exchange and connection to the PHS network. The PHS indoor coverage system consists of an extension base station (hereinafter referred to as extension CS (cellStation)) and an extension control device. Here, the PHS extension terminal is a PHS public terminal that anyone can purchase and sell on the market. PHS public terminals (PHS extension terminals) logged into the PHS indoor coverage system can be use...
