Description

Personal wireless base station and its call processing method {Method of Call Processing for Private Base Station and Apparatus of the same}

The present invention relates to a private base station (PBS) and a call processing method thereof, and includes a called number in a hybrid terminal (hereinafter referred to as a hybrid terminal) that can be used in combination with mobile communication and a wireless telephone. The present invention relates to a personal radiotelephone base station and a call processing method thereof for connecting a local telephone call even when the called number includes a local area code when the call is input from the hybrid terminal to the personal radiotelephone base station.

Here, the personal wireless telephone base station is a device that is connected to a wired telephone network and provides a call to a user's wireless terminal, and receives a radio wave carrying a voice signal from the wireless terminal in a cordless telephone 1 (CT1) home. It transmits a signal through a wired telephone network.

The hybrid terminal can be used by changing the mutual setting in the mobile communication and wireless telephone mode. When the user is moving, the mobile terminal can be connected to the mobile communication network through the mobile communication base station. It can be connected to a wired telephone network.

When the user wants to use the mobile communication and the wireless telephone at the same time, the hybrid terminal can support both communication methods as one hybrid terminal even though the terminal is not separately provided for the two communication methods. It offers economical advantages and eliminates the inconvenience of carrying two terminals.

However, in the related art, there is a problem that occurs when a landline telephone call is made through a personal wireless telephone base station with a telephone number including a local area code stored in an address book of a hybrid terminal. In more detail, the phone number stored in the address book of the hybrid terminal generally includes a local number to use mobile communication even if it is a local phone number. However, when trying to make a call from downtown to downtown, if the area code is included in the local telephone number, the call cannot be connected.

For example, suppose the telephone number stored in the address book of the user's hybrid terminal is "02-565-6727" and the user's residential area is Seoul (the user's personal wireless telephone base station is connected to the landline network in the Seoul area). . At this time, the number "02" is a value representing the area code of Seoul. If the user wants to make a telephone call through a personal wireless telephone base station connected to a wired telephone network in the Seoul area in the hybrid terminal, the area code of the city of Seoul becomes an unnecessarily attached number and such a call attempt fails.

That is, the telephone number stored in the address book of the hybrid terminal is generally stored including the area code, so that the user calls through the personal wireless telephone base station connected to the wired telephone network of the same area as the area code with the telephone number stored in the hybrid terminal. There was a lot of inconvenience in doing.

Another inconvenience arises when a personal radiotelephone base station is used in an office equipped with a private exchange. In general, when there is a private exchange in the premises, an attempt should be made to include the external line identification number in the telephone number. Therefore, when a user wants to make a call to "02-565-6727" in such an office, the user may include the external line identification number "9" (here, the external line identification number is "9"). You should try to call 02-565-6727 ".

Therefore, in the conventional method of processing a call by a personal wireless telephone base station, a user cannot use a telephone number including an area code stored in a hybrid terminal as it is, and when used in an office, the user includes a telephone line by including an external line identification number. There was an inconvenience to try.

An object of the present invention is to solve the above problems, when a user wants to make a call through a wired telephone network connected to a personal wireless telephone base station as a hybrid terminal, the user modifies the phone number stored in the hybrid terminal The present invention provides a personal wireless telephone base station and a call processing method thereof so that they can be used without modification.

Another object of the present invention is that when a personal wireless telephone base station is used in an office equipped with a private exchange, a telephone number or a user stored in a hybrid terminal regardless of whether an external line identification number is included in a telephone number that a user wants to call. The present invention provides a personal wireless telephone base station and a call processing method for making a call to an input telephone number.

In order to achieve the object as described above, the call processing method of a personal radiotelephone base station in which a mobile communication and wireless telephone combined terminal according to the present invention is used, receiving a called number from the hybrid terminal, from the called number; Extracting an area code, determining whether the extracted area code matches a preset area code, if the area code is the same as a preset area code, removing the area code from the called number and the area Characterized in that it comprises the step of calling to the called party number is removed.

In the case where the personal radiotelephone base station is connected to the private exchange, the call processing method of the personal radiotelephone base station according to the present invention determines whether the called number is an external line number, and when the called number is an external line number, And inserting a predetermined external line identification number into the called number.

The personal wireless telephone base station apparatus according to the present invention includes a processing function setting unit for setting an area code of a wired telephone network to which the personal wireless phone base station is connected, a memory for storing the set area code, and a called number received from the hybrid terminal. Called number processing unit for extracting the area code from the area code to remove the area code overlapping with the preset area code, wired telephone network transmitter for transmitting voice signals to the wired telephone network, wired telephone network receiver for receiving voice signals from the wired telephone network, And a wireless terminal receiver for transmitting a voice signal from a wireless terminal transmitter for transmitting a voice signal and a hybrid terminal.

When the private radiotelephone base station is connected to the private exchange, the processing function setting unit may further perform a function of setting an external line identification number for identifying the external line of the private exchange, and the memory may be configured to identify the external line of the private exchange. An external line identification number is further stored to store an external line identification number for the receiver. The called number processor is configured to set an external line in advance when the called number is an external line number and the called number does not include an external line identification number. And a function of inserting a recognition number into the called number is further performed.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view illustrating a telephone connection of a mobile communication and wireless telephone composite terminal through a mobile communication network and a wired telephone network according to the present invention.

Referring to FIG. 1, the mobile communication network may simply include a base station 110, a base station controller 120, a wireless switching center 130, a gateway station 140, and the like. The wired telephone network may include a personal wireless telephone base station 150. And private exchange office 160. Here, the private exchange office 160 is a device for configuring a private telephone network separately or simultaneously using a wired telephone network in an office used by a large number of people, and may not be used in a general home.

The wireless switching center 130 may include a mobile switching center (MSC), a home location register (HLR), a visitor location register (VLR), and the like. In addition, the gateway station 140 performs a function of interconnecting different networks such as a mobile communication network and a public switched telephone network (PSTN) or a mobile communication network and an internet data communication network.

The hybrid terminal 100 may be provided with a voice call or other communication service through a mobile communication network connected to the base station 110 when the mobile terminal is set to a mobile communication mode according to a user's request. When the personal wireless phone base station mode is set, a voice call or other communication service may be provided through a wired telephone network connected to the personal wireless phone base station 110. Here, when the personal radiotelephone base station 110 is used in an office equipped with a private switching center, it is connected to a wired telephone network through the private switching center 160.

As such, the hybrid terminal provides various conveniences to the user. For example, a user using a hybrid terminal does not need to have a separate terminal for mobile communication and a wireless telephone. If using a landline telephone is cheaper in consideration of call rates, a user has a separate terminal at home or at the office. You can use a cheap and convenient landline phone without having to.

2 is a diagram illustrating an example in which a hybrid terminal according to an embodiment of the present invention is used.

Referring to FIG. 2, when a user wants to make a call through a wired telephone network instead of a mobile communication network, when the user makes a call from the hybrid terminal 200, the personal wireless telephone base station 210 receiving the signal of the hybrid terminal calls the user. To connect to a wired telephone network.

The personal radiotelephone base station 210 may be used in a general home, but may also be used in an office or the like. However, in an environment shared by a large number of users, such as an office, a private exchange is generally provided to connect an premises or an external line. Therefore, the personal radiotelephone base station 210 is configured to be used in an office as well as a general home.

Since the user's call request is performed using the called party number which is the other party's phone number, the user may attempt to call the called party number previously stored in the address book of the hybrid terminal 200.

The personal wireless telephone base station 210 according to the present invention may perform a function of connecting a user's call to the called number regardless of the area code even if the called number desired by the user includes the area code.

More specifically, if the personal wireless telephone base station 210 is connected to a wired telephone network in the Seoul area and the user calls the hybrid terminal 200 in the personal wireless telephone base station mode, the user may read the address book of the hybrid terminal 200. One called number stored in advance may be used, and even if the called number includes the area code of Seoul, the personal wireless telephone base station 210 according to the present invention may provide a call to the user.

For example, if a called number that a user wants to call is stored as "02-565-6727" in the address book of the hybrid terminal, and the personal wireless telephone base station 210 is connected to the wired telephone network of the Seoul area, Should dial the called number "565-6727". However, in the personal wireless telephone base station of the present invention, even if the user makes a call to the called number "02-565-6727", regardless of this, the called number "565-6727" can be correctly connected.

Looking at another function, when the personal radiotelephone base station 210 is used in an office equipped with a private exchange, the user generally has to make an outgoing call including an external line identification number indicating the external line. However, the personal wireless telephone base station 210 of the present invention can connect the call to the called number according to the user's request even if the called number does not include the external line identification number.

3 is a functional block diagram of a personal radiotelephone base station according to an embodiment of the present invention.

Referring to FIG. 3, the personal wireless telephone base station according to the present invention includes a memory 325, a called number processor 320, a processing function setting unit 310, a wired telephone network transceiver 330, and a wireless terminal transceiver 340. It may include. Each functional block will be described below.

The processing function setting unit 310 may include an area code and an external line recognition number setting function according to a user's request.

First, the area code is to set the area code of the wired telephone network to which the personal wireless phone base station is connected. When the personal wireless phone base station is used in the Seoul area, the user may set the area code of Seoul. Currently, the area code of Seoul, South Korea is "02", so that the user can select and set the area code "02" in the personal wireless telephone base station.

The reason for setting such an area code is that if the set area code and the destination number received from the hybrid terminal include the same area code, the area code included in the destination number is not available because the call is not possible when the same area code is sent to the destination number. This is to remove the.

And, when a personal radiotelephone base station is used in an office, the connection of an external line generally has to go through a private exchange provided in the office. Therefore, when the user makes an outgoing call, the external line identification number must be included in the called number so that the private exchange knows that it is the outside line. In general, the external line identification number will be understood that "9" is used.

Therefore, the processing function setting unit 310 allows the user to further set the external line identification number. The external line identification number set in the personal radiotelephone base station is the external line identification number set in the called party received from the hybrid terminal in the personal radiotelephone base station even if the user makes a call without including the external line identification number in the called terminal. By inserting, the call is possible.

The memory 325 stores an area code, an external line identification number, and the like of the wired telephone network set by the processing function setting unit. In addition, it will be appreciated that the memory 325 may further store information for the personal wireless telephone base station to determine whether the called number is the extension number or the external line number.

The called number processor 320 performs a function of making a call possible with respect to a called number received from the hybrid terminal. These performing functions are performed corresponding to various setting factors set by the processing function setting unit 310.

For example, by comparing and determining whether the area code is included in the called number received from the hybrid terminal and the area code set in the personal wireless telephone base station, the area included in the called number when the received called number and the set area code are the same. Remove the number and make the call to make the call possible.

In addition, when a private wireless telephone base station is connected to an external line through a private switch, it is determined whether the external line identification number is included in the called number and the external line is not included in the called number when the external number is not included in the called number. The call can be made by inserting the identification number.

The wired telephone network transceiver 330 transmits and receives a voice signal through a wired telephone network. When the voice signal is transmitted and received through a wired telephone network, it is modulated to a carrier wave and transmitted or received. Therefore, the wired telephone network transmitter / receiver 330 receives a carrier carrying a voice signal of the other party from a wired telephone network to which a personal wireless telephone base station is connected, and extracts a voice signal, and transmits the user's voice signal by modulating it on the carrier. Perform the function.

The wireless terminal transceiver 340 transmits and receives a carrier wave from the hybrid terminal. The carrier uses a frequency in the 900 MHz band between the hybrid terminal and the personal radio base station. In a hybrid terminal, a user's voice signal is modulated to such a carrier and transmitted to a personal wireless telephone base station. The carrier cannot be directly transmitted through a wired telephone network.

In the DCN mobile communication wireless network, a carrier of 800 MHz band is used between a mobile communication terminal and a base station. A carrier in the 40 MHz band or the 900 MHz band is used between the wireless telephone and the personal wireless telephone base station. However, considering the similarity of the propagation characteristics of these two communication methods in the hybrid terminal used for mobile communication and wireless telephone, the 900MHz band that can similarly configure the RF (Radio Frequency) module that processes radio frequency It is preferable to use a carrier of.

Therefore, the reason why the carrier of the 900MHz band is used is that the configuration of the RF module changes little when the communication method is switched from the hybrid terminal to the mobile communication and the radiotelephone, and thus the implementation thereof is simple and inexpensive.

Accordingly, the wireless terminal transceiver 340 extracts the user's voice signal from the carrier received from the hybrid terminal, and the extracted voice signal is modulated by the wired telephone network transceiver 330 and transmitted through the wired telephone network. In addition, the voice signal of the other party received from the wired telephone network is modulated by the wireless terminal transceiver 340 and transmitted to the hybrid terminal.

4 is a diagram illustrating a processing procedure of a processing function setting unit of a personal radiotelephone base station according to an embodiment of the present invention.

Each step of the processing function setting section will be described below.

In step S410, the area code of the wired telephone network to which the personal wireless telephone base station is connected is set. For example, if a personal wireless telephone base station is connected to a wired telephone network in Seoul, the area code is set to "02".

In step S420, it is determined whether the external line is connected via the private exchange. If the private radiotelephone base station is connected to an external line via a private switch, the flow proceeds to step S430. In this step S430, the external line identification number is set. For example, if the external line identification number of the private exchange is "9", it is set. This external line identification number can of course be changed depending on the setting of the private exchange.

In step S440, the area code set in step S410 is stored, and if the personal radiotelephone base station is connected to an external line via a private switchboard, the external line identification number set in step S430 is stored and the procedure of the processing function setting unit ends.

5 is a diagram illustrating a processing procedure of a called number processing unit of a personal radiotelephone base station according to an embodiment of the present invention.

Hereinafter, each step of the procedure for processing the called number in the called number processing unit of the personal wireless telephone base station.

In step S510, the personal wireless telephone base station receives the called number from the hybrid terminal. The called number may be a user input directly to the hybrid terminal and may be a telephone number stored in the hybrid terminal.

That is, the user may make a call using the called number including the area code pre-stored in the address book of the hybrid terminal. If the wired telephone network recognizes the area code or the external line identification number in advance, the user may directly call the hybrid terminal. You can also call by entering the correct destination number.

In step S520, it is determined whether the called number received in step S510 is a called number of an office equipped with a private exchange. Such a telephone number in the office is generally referred to as an "extension number." In step S520, it is determined whether the received called number is an extension number by using information about the extension number preset in the personal wireless telephone base station.

Here, assuming that there are several offices separated from each other in one company, each office may have a separate private exchange. At this time, each private exchange may include a unique identification number.

For example, if Company A has Office A, Office B, and Office C, and the Private Exchange is Recognition Number "100", Recognition Number "200", and Recognition Number "300", respectively, the extension is such an editorial. It may include an exchange identification number.

In step S530, when the called number received from the hybrid terminal is an external telephone number, it is determined whether the called number includes the external line identification number. The external line identification number can be arbitrarily set at the private exchange, and generally uses "9". This external line identification number allows the private exchange to recognize that the called number is an external telephone number when the private wireless telephone base station is connected to the external line through the private exchange.

Therefore, when the external line identification number is not included in the called number, the external line identification number can not be transmitted to the outside. In step S530, it is determined whether the external line identification number is included, and when it is included, the process immediately proceeds to step S550.

In step S540, when the called number does not include the external line identification number, the private wireless telephone base station inserts the external line identification number so that the private exchange can call the called number.

Steps S520, S530, and S540 are steps required when the private wireless telephone base station is connected to an external line through a private switch, and it can be found that the steps can be omitted for a private wireless telephone base station used in a typical home. Put it.

In step S550, it is determined whether the called number includes an area code. If the area code is included, the process proceeds to step S560. If the area code is not included, the process proceeds to step S580.

In step S560, it is determined whether the area code included in the called number matches the area code preset in the personal wireless telephone base station. If the outside line of the personal wireless telephone base station is connected to the Seoul area and the area code of Seoul is set in advance in the personal wireless telephone base station, the personal wireless telephone base station determines whether the area code included in the called number is the same as the Seoul area code. do.

In step S570, when the area code preset in the personal wireless telephone base station and the area code included in the called number are the same in step S560, the area code included in the called number is removed. In general, if the area code included in the personal wireless telephone base station and the area code included in the called number are the same, the user requests “local call”, and therefore, the area code included in the called number is unnecessary, and the user must remove the area code. The call is correctly connected to the called party number.

In step S580, the personal wireless telephone base station performs steps S520 to S570 to connect to the changed called number.

The above-described steps will be described with practical examples. Here, it is assumed that the personal wireless telephone base station is connected to an external line via a private switch, and the external line is a wired telephone network in Seoul.

First, when a user makes a call to the telephone number "02-565-6727" stored in the address book of the hybrid terminal, the personal wireless telephone base station receives this number as the called number. Since the called number is a number using an external line rather than an extension number, the personal wireless telephone base station inserts an external line identification number "9" into the called number. Therefore, the personal wireless telephone base station receives the called number "02-565-6727" from the hybrid terminal and finally changes the called number to "9-565-6727" to meet the user's request.

As described in FIG. 5, if the user directly inputs the called number into the hybrid terminal, the area code and the external line recognition number may be recognized and included in the called number, and the present invention may be related to the presence or absence of such recognition by the user. You can make a call to the destination number you requested.

That is, if the user makes a call through the conventional wireless wireless base station, the user must modify the called number including the area code stored in the address book of the hybrid terminal. Called number by presence can be sent without modification.

The dial tone corresponding to the voice signal and the called number of the user between the hybrid terminal and the personal wireless telephone base station is modulated and demodulated using a carrier of 900 MHz band (hereinafter referred to as a wireless carrier). It is not suitable for the wireless carrier received from to be transmitted directly over the wired telephone network.

That is, since the wired telephone network and the wireless telephone network use carriers having different frequencies, the wireless carrier that modulates the voice signal from the wireless telephone network cannot be transmitted to the wired telephone network as it is. Therefore, the voice signal must be extracted from the carrier and modulated to suit the carriers (wireless carrier and wire carrier) of each of the wired telephone network and the wireless telephone network.

The wireless terminal receiver 640 receives a wireless carrier carrying a modulated voice signal from the hybrid terminal and extracts the user's voice signal from the wireless carrier. The voice signal of the user is modulated to be suitable for a carrier wave (hereinafter, referred to as a wire carrier) of a wireline telephone network by the wireline transmission unit 610 and transmitted through a wireline telephone network.

Dually, the wired line receiver 620 receives a wired carrier carrying the voice signal of the other party received through the wired telephone network, and extracts the voice signal of the other party from the wired carrier. The voice signal of the other party is modulated to be suitable for the wireless carrier by the wireless terminal transmitter 630 and transmitted to the hybrid terminal through the wireless telephone network.

Hereinafter, a description will be given with reference to a process in which a user makes a call to a called number using the hybrid terminal 660 and a process in which a call with a counterpart corresponding to the called number is connected and a mutual call is connected between the user and the counterpart.
