A mobile Worldwide Interoperability for Microwave Access (WiMax) network system having a private network and a mobile Internet Protocol (IP) terminal processing method thereof are provided. A private access control router performs an initial access procedure for a WiMax terminal requesting initial access. When a mobile IP address is set in the WiMax terminal, a mobile IP registration procedure for the WiMax terminal is performed according to a mobile IP standard. When the WiMax terminal is a local subscriber WiMax terminal, a virtual IP address for accessing the private network mapped to the mobile IP address is registered in an IP mapping table. A single private access control router can process a local intranet service and a public Core Network (CN) service without an additional access control router and a local subscriber WiMax terminal can receive simultaneously the local intranet service and the public CN service without any special operation.

Mobile WIMAX network system having private network and mobile IP terminal processing method thereof

An apparatus and method for controlling a wireless terminal, including parameter information to control a camera function of the wireless terminal is set, a camera control message to automatically control the camera function is set to be transmitted through a message transmission unit, the wireless terminal obtains the camera control message periodically transmitted from the message transmission unit, and a camera mode is automatically converted through parameter information of the obtained camera control message, so that it is possible to protect the camera function of the wireless terminal from malicious use.

Apparatus and method for controlling wireless terminal

A call processing method and apparatus in a private wireless communication system or WPBX, by which when the WPBX service subscriber originates a PLMN voice call in the private wireless communication service zone without inputting the preset identification number, the call is forwarded to the PSTN and/or wired/wireless Internet linked to the WPBX instead of being sent to the PLMN so that the WPBX service subscriber can be provided with a more convenient communication service at a cheaper price when he/she wants to be provided with the PLMN service.

Call processing method and apparatus in a private communication system

A hybrid base station transceiver has an ATM matching unit for connecting a wireless terminal to an ATM-based communication network; an IP matching unit for connecting a wireless terminal to an IP-based communication network; a channel and RF processor for performing physical connection protocol processing and RF transceiving processing with the wireless terminal; and a routing processor for determining which network to which the wireless terminal is to connect to by analyzing a signal of OSI Layeror Layerreceived from the wireless terminal and for connecting the wireless terminal to the ATM-based or IP-based communication network through the channel and RF processor according to the analysis.
