How to Set Up Additional Functions in a Wireless Telephone in a Wireless Private Switching System

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless private switching system, and more particularly, to a method for setting a number of additional functions used in a conventional landline telephone.

The conventional Private Automatic Branch eXchange System is configured to accommodate a single line phone (SLP) or a digital phone (DGP). The private exchange system typically provides an incoming call function, an outgoing function, and the like to such a general telephone or a digital telephone to enable a call service. In addition to these typical functions, the private exchange system provides various convenient functions these days so that subscribers can feel more convenient during the call or city.

On the other hand, the private exchange system of today is evolving to accommodate not only ordinary telephones and digital telephones but also wireless telephones such as 2nd generation cordless telephones (CT-2). 1 is a view showing a connection configuration of a private telephone exchange system that accommodates CT-2 as well as a general telephone or digital telephone.

Referring to FIG. 1, the CTM 10 performs call processing in the SLP module 20 or the DGP module 30 when the corresponding phone number is a general extension (wired telephone) during incoming or outgoing processing. 2 Calls are processed in module 40. As shown in FIG. 1, the landline phone and the wireless phone are each composed of separate modules. In the case of the existing extension telephone module (SLP 20, DGP 30), the basic incoming and outgoing functions, as well as additional functions such as MLP (Muti-Line Phone) function 21 or automatic call distribution (ACD) Call Distribution) is also used to provide 22. On the other hand, the CT-2 40, which is a wireless telephone, is used in a limited form in that it provides only basic incoming and outgoing functions. Therefore, in the case of the CT-2 40, it would be desirable to use various additional functions used in the existing landline telephone. However, when the wired and the wireless are configured as separate modules as shown in FIG. 1, there is a hassle that the operation for adding a new function for the CT-2 40 should be performed separately from the wired telephone module.

Accordingly, it is an object of the present invention to provide a method in which each task is performed in an integrated module instead of an independent module when adding a new function in a wireless private exchange system.

It is another object of the present invention to provide a method for improving the efficiency of work when adding a function to a wireless telephone module in a wireless private switching system.

Still another object of the present invention is to provide a method of improving the reliability of a system by integrating a wired telephone module and a wireless telephone module in a wireless private switching system.

In order to achieve the above object, the present invention is to configure a multi-line telephone (MLP) or automatic call distribution (ACD) telephone together with a wired telephone module because the CT-2 is composed of its own module in the existing wireless private switching system. Considering the fact that it is not possible, we propose a method for integrating wired or wireless telephones into a single module to share a loop key (LPS) key and to configure the same ACD group. The present invention has the effect of allowing the registration of the functional telephone and the functions that can be used by existing wired subscribers can be used even in the wireless.

Figure 2 is a diagram showing the configuration of a wireless private exchange system according to the present invention.

3A and 3B are diagrams illustrating an incoming and outgoing processing flow of a next generation wireless telephone (CT-2) according to the present invention.

DETAILED DESCRIPTION A detailed description of preferred embodiments of the present invention will now be described with reference to the accompanying drawings. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted. In addition, the terms to be described below are terms defined in consideration of functions in the present invention, which may vary according to the intention or custom of the user or chip designer, and the definitions should be made based on the contents throughout the present specification.

2 is a view showing the configuration of a wireless private switching system according to the present invention, the wireless private switching system has a self-module independent of the CT-2 in the existing wireless private switching system multi-line phone with a wired telephone module This is to solve the problem that could not be configured as a (MLP: Multi-Line Phone) or an Automatic Call Distribution (ACD) phone. That is, the wireless private switching system according to the present invention can share a loop key (LPS) key by integrating a wired telephone or a wireless telephone into one module, and can be configured as the same automatic call distribution (ACD) group. As a result, registration of existing function phones and functions that can be used by existing wired subscribers can be used in wireless phones.

Referring to FIG. 2, the wireless private exchange system according to the present invention includes a CTM 100, an ATC 200, an STN 300, and a TRK 400. Compared to the conventional wireless private exchange system according to the present invention, the wireless private exchange system according to the present invention is a wired telephone (SLP, DGP) module and a wireless telephone (CT-2) module are integrated in the station (STN) station 300 , CTM-W block is included in the interior of the CTM 100. At this time, the function of CT-2 can be classified into wireless unique function, call unique function and additional function. Wireless unique function is processed in CTM-W (Wireless) block inside CTM 100, and call unique function is processed in STN 300. do. The add-on is handled in the CTM-W block as much as possible and, if not possible, in the STN 300. The CT-2's unique features include location registration, handover, and incoming / outgoing collision. Call-specific features include incoming, outgoing, trunk line calls, and dedicated line calls. Additional features include FWD (Forwarding), CAMP, Camp On Busy, and Pick-Up.

By configuring the wireless private switching system as shown in FIG. 2, it is possible to set a CT-2 telephone, which cannot be conventionally configured as a subscriber group, an MLP, or an ACD group, as a function phone. In the past, the CT-2 phone was used as a landline phone. In order to receive a call to the CT-2 phone, a separate phone number was assigned or the call was processed after the No Answer Time. However, since the present invention can implement a CT-2 phone as an MLP, if the LPS key is shared by configuring the MLP as a wireline phone, the ringing will ring simultaneously to the wired phone and the CT-2 phone for incoming calls. Accordingly, even when the subscriber is absent from his / her seat, the incoming call can be immediately answered using the CT-2 telephone.

In addition, when the CT-2 phone is configured as an ACD phone and registered as an ACD group, various services provided by the ACD phone can be provided through the CT-2 phone.

The operation of setting the CT-2 phone as a function phone is performed by designating the CT-2 phone as an MLP or ACD phone on the port synthesis screen in which the subscriber specifies the characteristics of each phone. At this time, wired telephones such as SLP and DGP can be designated as MLP or ACD telephones just like CT-2 telephones.

If the CT-2 phone is set to MLP, specify the CT-2 phone and the landline phone as the LPS key in the digital phone (DGP) information, enter the telephone number of the landline phone in the CT-2 phone, and press CT- in the landline phone. 2 Register the phone number with the LPS key so that the phone is shared with each other by the LPS key. In this configuration, when a call is received by MLP, a message previously provided only to a wired telephone is provided to a corresponding wireless base station (CFP: Cordless Fixed Part) by a wireless protocol, and this CFP is a CT that shares an LPS key. -2 Provide a message to the telephone so that the corresponding CT-2 telephone is called. When calling, if the CT-2 phone only catches the channel of a specific base station, the STN module 300 can handle all the calls, thus enabling the use of all the functions of the fixed line phone.

When the CT-2 phone is set as an ACD phone, it is set as an ACD phone by inputting the CT-2 phone as a member of the ACD group to be designated. In this configuration, since the CT-2 telephone becomes a member as long as the ACD service is provided, the incoming call is performed in a predetermined order when the incoming ACD representative number is received. That is, when the order of the CT-2 telephones is established, the existing ringing message is converted to the wireless protocol and provided to the corresponding CT-2 telephone, so that the ACD group can answer the incoming call. In the case of a call origination, as with the MLP, if only the radio channel of a specific base station is caught, the call is processed in the same way as the flow performed in the conventional fixed line telephone.

3A and 3B are diagrams showing the processing flow for call origination and reception performed when the CT-2 telephone is set as an MLP or ACD telephone as described above.

Referring to FIG. 3A, when a call is originated, the CFP transmits an ID_OUTCALL_REQ message to the CTM-W block of the CTM 100 and transmits an FA message. In response, the CTM-W block sends a FI message and a CC_IND message to the corresponding CFP. The CFP transmits a CC_ACK message in response to the transmitted CC_IND message. In this case, the CTM-W block transmits a HOFF message to the STN 300 in response to the transmission of the CC_ACK message, the CFP transmits the KP message to the CTM-W, and the CTM-W transmits the DIGIT to the STN 300 for call origination. To lose.

Referring to FIG. 3B, when a call is received, the STN 300 transmits INCALLIND_MSG to the corresponding CFP. In this state, when the CFP transmits INCALL_REL_MSG to the CTM-W, the CTM-W responds to the SIG_MSG message, the FI message, the BAS_CAP message, and the CC_IND message in sequence, and the CFP sends the CC_ACK message, and then the CTM-W. Calls the incoming call by sending a HOFF message to the STN 300.

As described above, the present invention, unlike the conventional CT-2 telephone has an independent call processing module can perform only a simple call function, by integrating into a single module like a general landline telephone, many of the conventional landline telephone provided Allow additional functions to be performed on the CT-2 phone. In particular, if the MLP can be configured and the wired telephone and CT-2 telephone are configured as MLP to share the LPS key, calls received by the wire telephone are also received by the CT-2 telephone, and calls received by the CT-2 telephone are It is also called by landline. Accordingly, there is an advantage that the subscriber can respond to the call that is received by wire in the absence using the CT-2 telephone. In addition, since the CT-2 phone can be configured as an ACD phone, there is an advantage that the ACD function can be performed in the CT-2 phone.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. For example, in the detailed description of the present invention, the wireless telephone is described as CT-2, but the present invention can also be used for a wireless telephone such as DECT. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.
