Description

       Auto Re-Calling Control Method At The Internal wired, wireless network Co-Service System in wired / wireless integrated service system based on complex wireless terminal

The present invention relates to an automatic call forwarding method, and in particular, when an incoming call fails for a complex wireless terminal providing a function of a wireless telephone and a cellular phone, the caller automatically attempts to receive a call through another network. The present invention relates to an automatic call forwarding method in a wired / wireless integrated service system based on a complex wireless terminal that enables a call without retrying call setup.

The most deemed closest communication in life to the general public is a landline telephone using a public telephone network.

In addition to such landline telephones, home communication devices that can only be moved in residential areas of users began to appear in Korea since the late 1970s, and are commonly referred to as cordless phones.

This radiotelephone has a frequency range of 46 / 49Mhz, an indoor communication distance of 50m, a channel spacing of 25khz, and FM modulation. MCA (Multi Channel Access) method, which is called a request channel method, is commercially available.

In the 1990s, wireless phones in the 900 MHz band appeared in consideration of the improvement of call quality.

As described above, a cordless telephone that is made to be used only in a residential area by wirelessizing the handset of a home general telephone is called CT-1 (First Generation Cordless Phone).

CT-1 can only be used at home, so it cannot be used in public places. In order to improve this point, the first generation cordless phone (CT-2) system, called the outgoing cell phone, was first proposed in the UK in 1989. Has been adopted as a European standard and is currently being serviced in several countries.

If you express the features of CT-2, you can express it as a pedestrian wireless public telephone that can be used as a CT-1 at home and can walk while walking within the 200m radius used as a public telephone in public places.

The disadvantage of CT-2 is that there is no incoming call, no handover. The system that emerged to compensate for these shortcomings is called CT-3 (Third Generation Cordless Phone).

CT-3 can be classified into private network and public network according to the purpose of use, and can be explained mainly from private exchange system (PBX).

Conventionally, private communication system is mainly used for communication system used for business in building, and wireless system is emerged as wireless communication system (Wireless PBX) which makes this system wireless and enables mobile communication in building. DECT can also be seen as a system.

The DECT (Digital European Cordless Telephone) system, a representative example of the CT-3 system, was adopted as a European standard in March 1992 by the European Telecommunications Standards Institute (ETSI).

The main characteristic of this system is that the wireless access method is TDMA method and uses 2Ghz band and the channel bandwidth is 1.73Mhz and has 12 time slots per channel.

By developing the CT-3 system to the public network level by supplementing system functions such as handover and roaming, low-tier PCS, a personal communication system evolved from wireless telephones, a system that realizes personal communication that enables communication with anyone, anytime, anywhere (Personal Communication Service) has emerged.

Low Tier Personal Communication Service (PCS) allows wireless and pedestrian and indoor services to be provided as a basis, such as DECT in Europe, Personal Hand-phone System (PHS) in Japan, and PACS in the United States. (Personal Access Communication Service).

On the other hand, there is a high tier Personal Communication Service (PCS) that is microcelled to provide vehicle-oriented services including pedestrians by developing analog cellular technology as a counterpart to the low tier Personal Communication Service (PCS).

Analog cellular, which is the foundation of High Tier Personal Communication Service (PCS), was introduced in October 1983 by AMPS (Advanced Mobile Phone Service) developed by Bell Lab, and introduced the cell concept in the 824 ~ 894Mhz band. The channel band is 30kHz and the modulation method FM.

Analog cellular systems have been used in Europe such as NMT (Nordic Mobile Telephone), TACS (TAC), and NTT.

However, as the number of mobile subscribers increases rapidly in the late 80s, the system has emerged as a way to improve the limitations of capacity and the deterioration of communication quality and various demands of services.

In order to improve capacity, communication quality and data service, which is a disadvantage of analog cellular, Korea developed narrowband CDMA method and started commercial service since early 1996. In the United States, IS-95 CDMA was standardized in July 1993. Both IS-54 TDMA schemes have been developed.

In addition, the GSM (Groupe Special Mobile) method, which used TDMA in Europe in pan-Europe, began earlier than others, and it is characterized by interconnection between European countries.

And in Japan, in early 1993, PDC (Public Digital Communications) method using TDMA was commercialized.

However, such a digital cellular system can be regarded as having solved the call quality and a certain amount of capacity, but can not be regarded as a system that can be used by everyone in the public at low cost, that is, it is not suitable for providing a universal service.

Therefore, what has evolved to become a universal service for digital vehicle mobile phone systems can be called High Tier Personal Communication Service (PCS), which has the advantages of high speed mobility, simple network configuration, and the use of digital cellular technology.

High Tier Personal Communication Service (PCS) systems include Up-band IS-95 CDMA, which evolved from IS-95 CDMA, and DSC-1800 (Digital Communication System), which evolved from GSM.

Meanwhile, as described above, the development of a personal communication service (PCS) system can be divided into a high tier personal communication service (PCS) and a low tier personal communication service (PCS). It is progressing to accommodate the tier method, and the low tier method is also progressing to accommodate the high tier method and ultimately is being integrated into IMT-2000 (FPLMTS, Future Public Land Mobile Telecommunication System).

The communication network of IMT-2000 is a structure of interworking structure by integrating wired and wireless. A network capable of high speed data transmission (384kbps) from low speed data transmission (14.4kbps), which is a wireless environment, is constructed. Many experts predict that the activation of the Internet will become visible.

Recently, various wired / wireless integrated service systems have been developed to integrate wired and wireless networks such as public telephone networks and mobile communication networks, which are already established as a preliminary stage of the IMT-2000, to enable wired and wireless integrated services.

In addition, in recent years, as a wireless terminal having a complex function capable of simultaneously providing a wireless telephone function and a mobile communication function in terms of a terminal, a wireless telephone service through a public telephone network can be provided using a single wireless terminal. At the same time, mobile communication services can be provided using a mobile communication network.

However, the conventional method using a wireless terminal having a complex function has a problem that the called party has to retry setting up a call to another network when a call fails in one network because the general public telephone network and the mobile communication network are separated.

Accordingly, the present invention has been made to solve the above problems, and when the incoming call fails to receive the complex wireless terminal providing the wireless telephone function and the mobile communication function through the other network automatically when the incoming call fails An object of the present invention is to provide an automatic call forwarding method in a wired / wireless integrated service system based on a composite wireless terminal that allows a caller to make a call without retrying a call setup to another network.

It is done.

Now, with reference to the drawings of Figure 1 will be described in detail a preferred embodiment of the present invention.

1 is a network structure diagram of a wired / wireless integrated service system based on a composite wireless terminal to which the present invention is applied.

Referring to the drawings, the wired / wireless integrated service system based on the composite wireless terminal to which the present invention is applied, the composite wireless terminals 110 and 112, the wireless telephone access device 120, the switchboard 130 of the public telephone network, the wired / wireless integrated service control The station 140, the base station controller 150, and the base station 160 are provided.

The composite wireless terminals 110 and 112 may receive a wireless telephone service through the wireless telephone access device 120 and may receive a mobile communication service through the base station 160 of the mobile communication network.

The composite wireless terminals 110 and 112 are provided with two radio frequency (RF) modules to receive a mobile communication service through the base station 160 with one RF module and a wireless telephone access device with another RF module. Through 120, a wireless telephone service may be provided.

The hybrid radio terminals 110 and 112, which are provided with two RF modules and receive a mobile communication service and a radiotelephone service, are called hybrid hybrid radio terminals.

The hybrid hybrid wireless terminal 110 and 112 generally includes a wireless telephone cellular phone unit provided with a wireless telephone service and a mobile communications cellular phone unit provided with a mobile communication service. It consists of the main control part.

Here, the wireless telephone cellular phone unit is composed of a wireless telephone frequency processing unit and a wireless telephone control unit. The wireless telephone frequency processing unit is provided with a separate antenna, unlike an antenna provided by the mobile communication cellular phone unit. 120) to communicate with.

In addition, the mobile communication cellular phone unit is also provided with a separate antenna, and performs communication with the base station 160 by using a dedicated mobile communication frequency using the provided antenna.

That is, in the hybrid type hybrid wireless terminal 110 and 112, when communicating with the radiotelephone access device 120 embedded in the landline, the frequency band of the radiotelephone is used, but the communication with the base station 160 is performed. By using the frequency used for mobile communication, two different band frequencies are used.

In general, it is advantageous for a user to receive a wireless telephone service because a wireless telephone service through a public telephone network is cheaper than a mobile communication service using a general mobile communication network.

Therefore, a holder of the hybrid hybrid wireless terminal 110, 112 can designate that only the wireless telephone can be used by using the built-in user menu when moving to an area where the wireless telephone is available.

In addition, there is another type of composite wireless terminal (110, 112) is a composite wireless terminal of the dedicated Frequency Assignment (FA) method, the composite FA terminal of the dedicated FA method is only an RF module that processes the signal of the frequency band of the mobile communication network In addition, the mobile communication service may be provided through the base station 160 of the mobile communication network as well as the wireless telephone service through the wireless telephone access device 120.

In this case, the frequency used by the dedicated FA terminal 110 and 112 uses a frequency band of a general mobile communication network instead of a conventional wireless telephone frequency band.

When the dedicated FA type composite wireless terminal 110 or 112 moves to an area in which a wireless telephone service is provided, the composite wireless terminal 110 or 112 starts to receive an RF signal emitted by the wireless dial-up device 120 or a dedicated pilot. When the reference pilot is taken, the composite wireless terminals 110 and 112 automatically recognize that they have entered the wireless telephone service area and switch to the wireless telephone mode.

Therefore, in the dedicated FA composite wireless terminals 110 and 112, when the user carries the composite wireless terminals 110 and 112 and moves to an area where the wireless telephone service is provided, the mobile communication service is not provided.

In general, it is advantageous for a user to receive a wireless telephone service because a wireless telephone service through a public telephone network is cheaper than a mobile communication service using a general mobile communication network.

However, when a user wants to receive a mobile communication service using a mobile communication network even in a region where a wireless telephone service is available, when the user selects a mobile communication service providing mode using a menu provided in the composite wireless terminals 110 and 112, the wireless telephone is provided. Mobile communication service can be provided even in the area where the service is provided.

Next, a hybrid hybrid wireless terminal 110, 112, which is a hybrid of a hybrid scheme and a dedicated FA scheme, may be implemented. The hybrid hybrid wireless terminal 110, 112 may be an RF module capable of processing a frequency used for a mobile communication network service. When moving to an area that provides a wireless telephone service to provide a dedicated FA for wireless telephone service and FA for general mobile communication services at the same time to provide a wireless communication service as well as to provide a mobile communication service.

The hybrid hybrid wireless terminal 110, 112 starts receiving the RF signal emitted by the wireless dial-up device 120 when the mobile telephone service is moved to an area where a wireless telephone service is provided, or sets a dedicated pilot as its reference pilot. If a reference pilot is set, the composite wireless terminals 110 and 112 automatically recognize that they have entered the wireless telephone service area, so that the wireless telephone service can be used by driving an RF module for the wireless telephone.

Of course, if it is still possible to receive the service from the base station 160 of the mobile communication network hybrid composite wireless terminal (110, 112) provides a mobile communication service at the same time.

In general, it is advantageous for a user to receive a wireless telephone service because a wireless telephone service through a public telephone network is cheaper than a mobile communication service using a general mobile communication network.

Therefore, the user of the hybrid hybrid wireless terminal 110, 112 can be set using a built-in menu so that only the wireless telephone can be used when moving to an area where the wireless telephone is available.

On the other hand, the wireless telephone connection device 120 is embedded in a wired telephone and includes a wireless circuit portion, a baseband circuit portion, a telephone network connection portion, a control circuit portion, and a power supply circuit portion.

In general, the baseband circuit portion of the radiotelephone connection device 120 compresses and expands a voice signal for wireless transmission, modulates and demodulates a connection sequence control signal with the composite wireless terminals 110 and 112, and synthesizes a voice signal and a control signal. Separation and so on.

The radio circuit unit modulates and demodulates a baseband signal to a radio frequency, amplifies a transmit / receive signal at an antenna, oscillates a carrier frequency, detects signal levels of other channel frequencies, and the like.

The control circuit has overall control and includes a call name storage device, an identification device, a carrier sense circuit, and the like, which are essential as a control device of a radio station facility. The power supply circuit converts the necessary DC voltage into a commercial power supply and backs it up to the battery in case of power failure.

In addition, the wireless telephone access device 120 should further include a device capable of generating and controlling a frequency signal dedicated to a mobile communication network when using the composite wireless terminals 110 and 112 using a dedicated FA method.

Next, the wired / wireless integrated service control station 140 is an apparatus for providing interworking between a public telephone network and a mobile communication network, and provides subscriber information on subscribers of a wired / wireless integrated service system supporting a complex wireless terminal and a current callable telephone for each subscriber. The number is being saved.

Here, the subscriber information stored in the wired / wireless integrated service control station 140 includes a mobile communication telephone number used for a mobile communication network service, a telephone number of a home wireless telephone receiving a service through a public telephone network, and a telephone number of a business wireless telephone. , Landline phone, etc.

Of course, when the wired / wireless integrated service control station 140 stores the telephone number of the business wireless telephone, the extension number of the subscriber's business wireless telephone must be stored, and (Table 1) shows that the wired / wireless integrated service control station 140 It shows subscriber information that is being saved.

Subscriber Name / Phone Number Mobile phone number Home Wireless Phone Number Business wireless telephone number (extension number) Current call number Hong Gil Dong 016-111-1111 02-333-3333 02-334-3334 (112) 02-333-3333 Gil Sun Hong 016-111-1112 02-333-3334 02-334-3335 (114) 02-334-3335 (114)

Giljun Hong ...... ...... ...... ......

As can be seen from Table 1, for example, Hong-Gil-Dong has a mobile phone number of 016-111-1111, but it can be seen that the current area is 02-333-3333, which is a home wireless phone number. You can see that it is located.

In the following example, Hong Gil-soon can be found that the mobile communication phone number is 016-111-1112, but it is currently located in the workplace as a telephone call number 02-334-3335 (114).

In addition, as the currently available telephone number stored in the wired / wireless integrated service control station 140, the user designates a telephone number that can be called using his / her composite wireless terminal (110, 112). If you move to an area that provides wireless telephony service from a possible area, the user can register using ARS (Auto Recevier Service) or send a phone number change message to the wired / wireless integrated service control station 140 to change the phone number. have.

In this case, when the telephone number is changed by transmitting the telephone number change message, the composite wireless terminal 110 or 112 automatically transmits the telephone number change message to change the telephone number, or the user changes the telephone number. The telephone number change message can be transmitted and changed by a menu operation.

Of course, at this time, if only one subscriber can be designated as a telephone number to be provided with the wireless telephone service, it is not necessary to repeat this change unnecessarily.

Next, the switch 130 of the public telephone network performs a call setup operation from / to the composite wireless terminal 110 through the wireless telephone connection device 120 to enable a call.

The switch 130 of the public telephone network may perform a wired / wireless integrated service when an incoming call attempt to the composite wireless terminals 110 and 112 fails while performing a call setup operation for the composite wireless terminals 110 and 112. The control station 140 inquires whether the wired / wireless integrated service subscriber based on the composite wireless terminal.

When the switch 130 of the public telephone network receives a response signal of a wired / wireless integrated service subscriber based on a complex wireless terminal from the wired / wireless integrated service control station 140, the switch 130 requests transmission of a telephone number that is currently available for telephone and wired / wireless integrated service control. An incoming call is attempted using a currently available telephone number for the combined wireless terminal 110 or 112 received from the station 140. At this time, the wired / wireless integrated service control station 140 may transmit the service subscriber confirmation signal including the telephone number.

For example, when the exchange 130 receives a call setup signal to the business wireless telephone for Hong Gil-dong of (Table 1), the exchange attempts to receive the business wireless telephone, and if the incoming attempt fails, the wired / wireless integrated service control station 140 Attempt to make a call to 02-333-3333, the current phone number in).

Of course, at this time, if the exchange 130 attempts to call the current telephone number 02-333-3333, but also fails to receive the call can be implemented to try to call to the mobile communication number.

Next, the base station controller 150 of the mobile communication network performs a call setup operation from / to the composite wireless terminal 112 through the base station 160, so that the call is possible.

The base station controller 150 of the mobile communication network integrates wired and wireless when an incoming call attempt to the combined wireless terminals 110 and 112 fails (including no response) while performing a call setup operation for the combined wireless terminals 110 and 112. The service control station 140 inquires whether the wired / wireless integrated service subscriber based on the composite wireless terminal.

When the base station controller 150 receives the response signal of the wired / wireless integrated service subscriber based on the complex wireless terminal from the wired / wireless integrated service control station 140, the base station controller 150 requests the transmission of a telephone number that is currently available for the call. The incoming call is attempted using the currently available telephone number for the composite wireless terminal 110, 112 received from the 140.

For example, when the base station controller 150 receives a call setup signal to the mobile communication telephone number for Hong Gil-dong of Table 1, the base station controller 150 attempts to receive the mobile communication telephone number, and if the incoming attempt fails, the wired / wireless integrated service control. Attempt to call the current telephone number 02-333-3333 in the station 140.

Of course, at this time, if the base station controller 150 attempts an incoming call to 02-333-3333, which is a current phone number, and fails to do so, the base station controller 150 may implement the call to a business wireless telephone.
