Device and method for compatible public network and private network calling in personal hand-held telephone system

Technical Field

The present invention relates to a PHS (Personal handyphone System) communication network, and more particularly, to an exchange.

Background

Currently, personal hand-held telephone systems have been greatly developed as extensions and complements to landline telephones. With the increasing popularization of PHS services, the requirements of telecommunication users on the mobility and quality of services provided by PHS networks are becoming stricter. On one hand, when the traditional PHS mobile phone is used in PHS public network, when a user enters an office building, a market and other indoor places, because the coverage effect of wireless signals in the indoor is relatively limited, the communication signals are poor.

On the other hand, when the PHS communication technology is applied inside an enterprise, although the work efficiency can be greatly improved, the enterprise needs to purchase, install, manage and maintain an internal extension system based on the PHS private network mode, so that the high cost and the complex maintenance and management are hard to bear by most enterprises. Moreover, for the operators, the operators are reluctant to share the initial network construction cost and the later network management and maintenance for the enterprises because the PHS network used inside the enterprises cannot expand and improve the PHS network coverage of the operators.

Disclosure of Invention

Aiming at the defects of the PHS communication technology, the invention provides an enterprise-level switch compatible with public network calling and private network calling.

According to one aspect of the invention, a processing method of an enterprise-level switch compatible with public network calls and private network calls is provided. The method can be realized by the following steps:

(1) the enterprise-level switch receives a call request initiated by a mobile phone and judges the network type of a calling party according to the call request;

(2) if the calling party belongs to a private network user, the enterprise-level switch performs user validity check on the calling party, and if the user validity check is passed, communication connection is established between the calling party and the called party; and

(3) if the calling party belongs to a public network user, the base station controller forwards the request to the public network, and if the user validity is checked, a communication connection is established between the calling party and the called party.

Preferably, when the call of the calling party is initiated from the public network mode or the public network channel of the dual-mode base station, the enterprise-class switch is configured as a base station controller. More specifically, when the enterprise switch is configured as a base station controller, it is connected to a gateway or a remote device of a wireless local telephone system based on a wireless network protocol standard in the PHS public network through an interface of the base station controller.

Preferably, the enterprise switch is configured as a private switch unit when a call from a calling party originates from a private network mode or a private network channel of a dual mode base station. More specifically, when configured as a private branch exchange unit, the enterprise-class switch is connected to the public switched telephone network through the private branch exchange unit's basic rate interface.

According to another aspect of the invention, a processing method of an enterprise-level personal handphone system switch compatible with public network calls and private network calls is provided. The method can be realized by the following steps:

(1) the enterprise-level switch judges the network type of the called party according to the incoming call route of the enterprise-level switch and broadcasts the call request;

(2) the called party sends a call response to the enterprise-level switch;

(3) if the called party belongs to a private network user, the enterprise-level switch completes user validity check on the called party, and if the user validity check is passed, communication connection is established between the called party and a calling party; and

(4) if the called party belongs to a public network user and the called party is paged through the public network, user validity check is completed through the public network, and if the user validity check is passed, communication connection is established between the calling party and the called party.

Preferably, when the communication terminal as the called party is from the public network, the enterprise-class switch pages the call request on the public network channel of the public network mode base station or the dual-mode base station.

Preferably, when the communication terminal as the called party comes from a private network, the enterprise-class switch pages the call request on a private network channel of its private network mode base station or dual-mode base station.

According to yet another aspect of the present invention, a switch compatible with public network calls and private network calls in a personal, hand-held telephone system is provided. It comprises the following steps:

the base station controller is configured to be connected with a gateway or remote equipment of a public network through an interface of the base station controller to establish communication connection for a communication terminal in the public network; and

and the user switch unit is configured to be connected with the public switched telephone network through the basic rate interface and establish communication connection for the communication terminal in the private network.

Preferably, the enterprise-class switch is connected with the public network mode base station, the private network mode base station and the dual-mode base station through the base station interfaces so as to provide network coverage of the public network and the private network at the same time. Further, the dual-mode base station comprises a public network channel and a private network channel.

Preferably, when the communication terminal in the public network is used as a calling party, the enterprise-class switch is used as a base station controller to initiate a call request on a public network mode base station or a public network channel of a dual-mode base station; when the communication terminal in the private network is used as a calling party, the enterprise-class switch is used as a user switch unit to initiate a calling request on a private network mode base station or a private network channel of a dual-mode base station.

Preferably, when a call is incoming to the enterprise switch from a base station controller interface connected to a gateway or remote device of the public network, the called terminal is paged at a public network mode base station or public network channel of the dual mode reference. When the user is called as the terminal user in the enterprise private network, the user is paged on the private network channel of the private network mode base station or the dual-mode base station.

The invention relates to a device and a method for compatible public network calling and private network calling of a personal hand-held telephone system, wherein an enterprise-level switch can judge the network type in real time and process the public network calling and the private network calling.
