- FIG. 1 is a view illustrating a network configuration of a system for providing a terminal switching service between a telematics terminal and a mobile terminal according to an embodiment of the present invention.
- the terminal switching service system comprises a mobile terminal 110, a telematics terminal 120, a base transceiver station 130, a mobile switching center 140, a mobile communication network 150, a home location register 160 and a terminal switching server 170.
- a subscriber gets in a vehicle and drives the vehicle, if the subscriber receives a mobile communication service with the mobile terminal 110, the likelihood of an accident is large, and thus when the subscriber gets in the vehicle, the subscriber may switch the mobile terminal 110 to the telematics terminal 120.
- the subscriber can receive a call destined for the mobile terminal 110 using the telematics terminal 120 and communicate with other subscriber through an external speaker and an external microphone of the telematics terminal 120.
- the mobile terminal 110 includes PDA (Personal Digital Assistant), a cellular phone, a PCS (Personal Communication Service) phone, a GSM (Global System for Mobile) phone, a WCDMA (Wideband CDMA) phone, a CDMA (Code Division Multiple Access)-2000 phone or an MBMS (Multimedia Broadcast and Multicast Service) phone.
- the telematics terminal 120 provides a typical telematics service, and in particular, provides a mobile communication service through an embedded mobile communication module. That is, the telematics terminal 120 is assigned a separate phone number and provides a subscriber with a mobile communication service in the same way as the mobile terminal 110.
- the subscriber in the vehicle connects to the terminal switching server 170 using the telematics terminal 120, selects a desired mobile terminal 110 for terminal switching, and requests profile switching (i.e. terminal switching).
- the terminal switching server 170 provides the telematics terminal 120 with a list of a plurality of mobile terminals, and receives selection of any one mobile terminal among the list from the subscriber.
- a family having one vehicle subscribes to a terminal switching service sets the telematics terminal 120 as an object for terminal switching, and stores information of mobile terminals 110 of each member of the family.
- the driver connects to the terminal switching server 170 using the telematics terminal 120, selects his/her mobile terminal among the mobile terminal list of the family provided from the terminal switching server 170 and requests terminal switching.
- an electronic control unit mounted in the vehicle may recognize a starting activation and transmit a terminal switching activation trigger signal to the telematics terminal 120, and the telematics terminal 120 may recognize the terminal switching activation trigger signal and request profile switching (i.e. terminal switching) to the terminal switching server 170.
- the subscriber may request terminal switching to the terminal switching server 170 by directly inputting a telephone number of his/her mobile terminal 110 into the telematics terminal 120. This can be variously applied according to change in design by persons skilled in the art.
- the telematics terminal 120 requests terminal switching, the mobile terminal
- the telematics terminal 120 is activated, so that the subscriber can use a mobile communication service with the telematics terminal 120, not with the mobile terminal 110.
- the base transceiver station 130 (BSC/RNC) is connected with the mobile terminal
- the base station controller/radio network controller controls the base transceiver station 130, and performs wireless channel assignment and release on the mobile terminal 110 and the telematics terminal 120, transmitter power control of the terminals 110 and 120 and the base transceiver station 130, determination of soft handoff and hard handoff between cells, transcoding and vocoding, or management and maintenance and repair of the base transceiver station 130
- the mobile switching center 140 performs basic and additional service processing, processing of incoming and outgoing calls of a subscriber, location registration and handoff, or interworking with other network, i.e. a public network or an intelligent network system. In particular, when terminal switching is made, the mobile switching center 140 intercepts a call originated from the mobile terminal 110 and provides the telematics terminal 120 with a voice/video call or a data call destined for the mobile terminal 110.
- the mobile switching center 140 stores and manages an inactive information of the mobile terminal 110 to intercept a service of the mobile terminal 110, and stores an identification information (for example, MSISDN) of the mobile terminal 110 corresponding to IMSI (International Mobile Subscriber Identity) of the telematics terminal 120 and provides the telematics terminal 120 with a mobile communication service destined for the mobile terminal 110 using the identification information.
- MSISDN International Mobile Subscriber Identity
- the mobile switching center 140 intercepts all calls originated from the mobile terminal 110 after terminal switching, but may not intercept an outgoing call for a specific function. For example, when the subscriber uses the telematics terminal 120 after terminal switching, although the subscriber wants to release the terminal switching, call origination of the mobile terminal 110 is intercepted, so it is not possible to release the terminal switching with the mobile terminal 110. Therefore, in the case that an outgoing call for terminal switching release is transmitted from the mobile terminal 110, the mobile switching center 140 allows origination of the corresponding call, so that terminal switching is released.
- the mobile switching center 140 stores and manages a function code information for terminal switching release, and when an outgoing call including the function code is transmitted from the mobile terminal 110, the mobile switching center 140 refers to the function code and allows origination of the corresponding call.
- the mobile communication network 150 is connected with the mobile switching center 140, the home location register 160 and the terminal switching server 170, and provides interface and signaling between each network equipment.
- the mobile communication network includes No. 7 network, and each network equipment operates while being connected to the No. 7 network.
- the home location register (HLR) 160 is a database for storing a service profile about a subscriber information of the mobile terminal 110 and the telematics terminal 120, and stores and manages identification numbers (IMSI or MSISDN), additional information and location information of the mobile terminal 110 and the telematics terminal 120, and information necessary for terminal switching according to the present invention.
- the home location register 160 stores and manages location information of the mobile terminal 110 and the telematics terminal 120, and in the case that the subscriber requests to switch from the mobile terminal 110 to the telematics terminal 120, the home location register 160 inactivates information of the mobile terminal 110 and activates information of the telematics terminal 120, so that a mobile communication service (for example, a voice/video call or a data call) provided to the mobile terminal 110 is provided to the telematics terminal 120.
- a mobile communication service for example, a voice/video call or a data call
- the home location register 160 activates information of the mobile terminal 110 and inactivates information of the telematics terminal 120, so that a mobile communication service (for example, a voice/video call or a data call) provided to the mobile terminal 110 is provided to the mobile terminal 110 as originally provided.
- a mobile communication service for example, a voice/video call or a data call
- FIG. 3 is a view illustrating an example of a table stored in the home location register
- the home location register 160 activates/inactivates a location information of the mobile terminal 110 used by the subscriber (that is, sets a terminal switching flag to T or '0'), according to terminal switching request of the subscriber.
- the home location register 160 that stores a profile information of the mobile terminal 110 of the corresponding subscriber, inactivates a location information (RNl) of the mobile terminal 110 (sets a terminal switching flag to '0') and activates a location information of the telematics terminal 120 (sets a terminal switching flag to T) by setting a location information (RN2) of the telematics terminal 120 to a location information of the mobile terminal 110.
- the home location register 160 inactivates a location information (RN2) of the telematics terminal 120 (sets a terminal switching flag to '0') and activates a location information (RNl) of the mobile terminal 110 (sets a terminal switching flag to T).
- RN2 location information
- RNl location information
- the terminal switching server 170 According to terminal switching request of the subscriber, the terminal switching server 170 provides terminal switching to the subscriber, and stores and manages information according to terminal switching. Preferably, when receiving a terminal switching request from the subscriber, the terminal switching server 170 inactivates information of the mobile terminal 110, and activates information of the telematics terminal 120 by the home location register 160. And, when receiving a terminal switching release request from the subscriber, the terminal switching server 170 activates information of the mobile terminal 110 and inactivates information of the telematics terminal 120 by the home location register 160.
- FIG. 2 is a flow chart illustrating a terminal switching step in the terminal switching service system according to an embodiment of the present invention.
- a subscriber requests terminal switching to the terminal switching server 170 using the telematics terminal 120.
- the telematics terminal 120 transmits to the mobile switching center 140 a terminal switching request signal including an identification information (for example, MSISDN) of the mobile terminal 110 and IMSI of the telematics terminal 120 via a wireless section (S201). That is, the telematics terminal 120 transmits to the mobile switching center 140 a terminal switching request signal including an identification information of the mobile terminal 110, received from the subscriber.
- the mobile switching center 140 transmits to the terminal switching server 170 the terminal switching request signal including the identification information of the mobile terminal 110 and the IMSI of the telematics terminal 120, received from the telematics terminal 120 (S203).
- the mobile switching center 140 transmits the terminal switching request signal to the home location register 160, receives a routing information toward the terminal switching server 170 in response to the terminal switching request signal, and transmits to the terminal switching server 170 the terminal switching request signal including the identification information of the mobile terminal 110 and the IMSI of the telematics terminal 120.
- a subscriber certification step may be performed between the telematics terminal 120 and the terminal switching server 170. That is, the terminal switching server 170 requires the telematics terminal 120 to input a password, and compares the inputted password with a terminal switching service subscriber information to perform subscriber certification.
- the terminal switching server 170 receives the terminal switching request signal as mentioned above, and inquires out IMSI of the corresponding mobile terminal 110 to a terminal information DB (S205). That is, the terminal switching server 170 inquires out IMSI of the mobile terminal 110 in the terminal information DB using the identification information (for example, MSISDN) of the mobile terminal 110 included in the terminal switching request signal.
- the terminal switching server 170 requests a location information of the telematics terminal 120 (for example, the mobile switching center (MSCl of FIG. 2) 140 information) to the home location register (HLRl of FIG. 2) 160 that stores a profile information of the telematics terminal 120, and receives a response to the request (S207 and S209). That is, the terminal switching server 170 transmits the IMSI of the telematics terminal 120 to the home location register (HLRl) 160 and receives a routing information of the mobile switching center (MSCl) 140 in response to the request.
- a location information of the telematics terminal 120 for example, the mobile switching center (MSCl of FIG. 2) 140 information
- HLRl of FIG. 2 160 home location register
- the terminal switching server 170 transmits the IMSI of the telematics terminal 120 to the home location register (HLRl) 160 and receives a routing information of the mobile switching center (MSCl) 140 in response to the request.
- the terminal switching server 170 transmits a terminal switching command including the location information (for example, the mobile switching center (MSCl of FIG. 2) 160 information) of the telematics terminal 120 to the home location register (HLR2 of FIG. 2) 160 that stores a profile information of the mobile terminal 110 (S211).
- location information for example, the mobile switching center (MSCl of FIG. 2) 160 information
- HLR2 of FIG. 2 home location register
- the home location register (HLR2) 160 that stores a profile information of the mobile terminal 110 receives the terminal switching command from the terminal switching server 170, inactivates a location information of the mobile terminal 110 stored and managed therein, and sets and activates the location information of the telematics terminal 120 included in the terminal switching command (S213). That is, not an actual location information of the mobile terminal 110, but the location information of the telematics terminal 120 is set as a location information of the mobile terminal 110 in the home location register (HLR2) 160 that stores a profile information of the mobile terminal 110, so that a service signal destined for the mobile terminal 110 is transmitted to the telematics terminal 120.
- the home location register (HLR2) 160 that stores a profile information of the mobile terminal 110 transmits the profile information of the mobile terminal 110 to the mobile switching center (MSCl) 140 where the telematics terminal 120 exists (S215).
- the mobile switching center (MSCl) 140 receives the profile information of the mobile terminal 110, and changes the profile information of the telematics terminal 120 into the received profile information of the mobile terminal 110 (S217). That is, the mobile switching center (MSCl) 140, where the telematics terminal 120 exists, maps an identification information (for example, MSISDN) of the mobile terminal 110 to IMSI of the telematics terminal 120, and stores and manages the mapping information.
- the information of the telematics terminal 120 is stored and managed in a visitor location register (VLR).

- the mobile switching center (MSCl) 140 searches for IMSI of the telematics terminal 120 in the mapping information using a called party information (for example, MSISDN of the mobile terminal 110) of the transmitted call, detects the telematics terminal 120 using the searched IMSI, and transmits to the telematics terminal 120 an incoming call to be transmitted to the mobile terminal 110.
- a called party information for example, MSISDN of the mobile terminal 110
- the home location register (HLR2) 160 that stores a profile information of the mobile terminal 110 transmits a mobile terminal inactivation command to the mobile switching center (MSC2 of FIG. 2) 140, where the mobile terminal 110 exists (S219).
- the mobile switching center (MSC2) 140 intercepts a service destined for the mobile terminal 110 and intercepts a call originated from the mobile terminal 110, so that the subscriber can not use a service with the mobile terminal 110.
- the subscriber can be provided with a service destined for the mobile terminal 110 through the telematics terminal 120, instead of the mobile terminal 110. Therefore, when the subscriber gets in a vehicle, the subscriber receives a mobile communication service of the mobile terminal 110 by the telematics terminal 120, and thus the subscriber can drive the vehicle safely.
- FIG. 4 is a flow chart illustrating a step for releasing terminal switching according to an embodiment of the present invention.
- an electronic control unit mounted in a vehicle senses that a subscriber is not in a driving state, for example stop of a vehicle during driving, trouble in the engine or stop of starting, and requests terminal switching release to the telematics terminal 120 (S401). That is, when the subscriber is not in a driving state, the subscriber releases the terminal switching to the telematics terminal 120 to use the mobile terminal 110 again. And, for privacy protection of the subscriber, i.e. to prevent another passenger from listening to a telephone conversion, in the case that there is another passenger in the vehicle, the electronic control unit may sense another passenger and request terminal switching release to the telematics terminal 120.
- the electronic control unit may request terminal switching release to the telematics terminal 120.
- the sensing of another passenger may be made by proximity reading using RFID (Radio Frequency IDen- tification) of the telematics terminal 120. That is, if the terminal-switched telematics terminal 120 senses a signal (that is, RFID) of a mobile terminal of a passenger other than the driver's mobile terminal 110, the telematics terminal 120 may request terminal switching release to the terminal switching server 170.
- RFID Radio Frequency IDen- tification
- terminal switching restoration according to a specific state of the subscriber's vehicle is made by the subscriber's setting. That is, in the case that the subscriber in a stopped state during driving does not set terminal switching restoration through setting of the telematics terminal 120, the subscriber can continuously use a mobile communication service with the telematics terminal 120.
- the telematics terminal 120 receives the terminal switching release request from the electronic control unit, and requests terminal switching release to the terminal switching server 170.
- the telematics terminal 120 requests terminal switching release to the terminal switching server 170
- the telematics terminal 120 transmits to the mobile switching center (MSCl of FIG. 4) 140 a terminal switching release request signal including IMSI and an identification information (for example, MSISDN) of the telematics terminal 120 via a wireless section (S403).
- the mobile switching center 140 transmits to the terminal switching server 170 the terminal switching release request signal received from the telematics terminal 120 (S405).
- the mobile switching center 140 transmits the terminal switching release request signal to the home location register 160, receives a routing information toward the terminal switching server 170 in response to the release request signal, and transmits the terminal switching release request signal to the terminal switching server 170.
- the terminal switching server 170 receives the terminal switching release request signal, and may perform subscriber certification with the telematics terminal 120. That is, the terminal switching server 170 may require the telematics terminal 120 to input a password, compare the inputted password with a terminal switching service subscriber information to perform subscriber certification, and perform terminal switching restoration.
- the terminal switching server 170 transmits the terminal switching release request signal to the home location register (HLRl of FIG. 4) 160 that stores a profile information of the telematics terminal 120 (S407). Then, the home location register (HLRl) 160 that stores a profile information of the telematics terminal 120 transmits the profile information of the telematics terminal 120 to the mobile switching center (MSCl) 140 where the telematics terminal 120 exists (S409).
- the mobile switching center (MSCl) 140 receives the profile information of the telematics terminal 120, and restores a profile information of the telematics terminal 120 stored therein using the received profile information of the telematics terminal 120 (S411). That is, the mobile switching center (MSCl) 140, where the telematics terminal 120 exists, mapped an identification information (for example, MSISDN) of the mobile terminal 110 to IMSI of the telematics terminal 120 in a profile information of the terminal- switched telematics terminal 120, and stored and managed the mapping information. However, according to terminal switching release of the subscriber, the mobile switching center (MSCl) 140 restores the identification information of the mobile terminal 110 mapped to the IMSI of the telematics terminal 120 to an identification information of the telematics terminal 120.
- MSISDN identification information
- the terminal switching server 170 transmits the terminal switching release request signal to the home location register (HLR2) 160 that stores a profile information of the mobile terminal 110 (S413). That is, the terminal switching server 170 extracts information of the mobile terminal 110 of the subscriber using a terminal switching service subscriber information stored and managed therein and information of the telematics terminal 120, and transmits the terminal switching release request signal to the home location register (HLR2) 160 that stores a profile information of the mobile terminal 110 based on the extracted information.
- HLR2 home location register
- the home location register (HLR2) 160 that stores a profile information of the mobile terminal 110 receives the terminal switching release request signal from the terminal switching server 170, activates a location information of the mobile terminal 110 stored and managed therein, and inactivates a location information of the telematics terminal 120 (S415). That is, not an actual location information of the mobile terminal 110, but the location information of the telematics terminal 120 was set as a location information of the mobile terminal 110 to the home location register (HLR2) 160 that stores a profile information of the mobile terminal 110, but the location information of the mobile terminal 110 is restored to an actual location information of the mobile terminal 110. Thus, a service signal destined for the mobile terminal 110 can be normally transmitted to the mobile terminal 110.
- the home location register (HLR2) 160 that stores a profile information of the mobile terminal 110 transmits a mobile terminal activation command to the mobile switching center (MSC2 of FIG. 4) 140 where the mobile terminal 110 is located (S417).
- the mobile switching center (MSC2) 140 transmits to the mobile terminal 110 a service destined for the mobile terminal 110, and accepts a call originated from the mobile terminal 110 to provide an original service.
- the electronic control unit senses the specific situation and transmits a terminal switching restoration trigger signal to the telematics terminal 120, so that terminal switching is automatically restored to the mobile terminal 110.
- the subscriber may request terminal switching release to the terminal switching server 170 by inputting a separate function code and a phone number of the telematics terminal 120 into the mobile terminal 110.
- the subscriber may request terminal switching release to the terminal switching server 170 by inputting
- the telematics terminal 120 transmits a terminal switching setting request/terminal switching release request through a voice/video traffic channel, and the terminal switching setting signal/the terminal switching release request signal is transmitted to the mobile switching center 140.
- an activation or inactivation information of the mobile terminal 110 is set to the mobile switching center 140, and thus the mobile switching center 140 accepts or intercepts a channel switching signal destined for the mobile terminal 110.
- the profile information of the mobile terminal 110 is stored in the mobile switching center 140 as a profile information of the telematics terminal 120, and thus the mobile switching center 140 transmits to the telematics terminal 120 a circuit switching signal transmitted to the mobile terminal 110.
- the present invention is not limited in this regard, and the present invention may be applied to a packet switching signal in the same way. That is, the telematics terminal 120 may set or release terminal switching through a packet switching network.
- a terminal switching setting signal/terminal switching release request signal is transmitted to SGSN (Serving GPRS Support Node) that provides a packet service, consequently to the terminal switching server 170, and in the same way as the mobile switching center 140, an activation/inactivation information of the mobile terminal 110 may be set to the SGSN and a profile information of the telematics terminal 120 may be set to the SGSN.
- the SGSN intercepts or accepts a packet service provided to the mobile terminal 110, so that the packet service provided to the mobile terminal 110 is provided to the telematics terminal 120.
- FIG. 5 is a view illustrating a configuration of a telematics terminal according to an embodiment of the present invention.
- a GPS unit 501 continuously communicates with a GPS satellite and transmits a received GPS signal to a telematics module 503. Then, the telematics module 503 checks a location information of a vehicle at the current point of time based on the GPS signal, computes a moving direction and a moving speed of the vehicle, and transmits to a control unit 507 a location information according to movement of the vehicle.
- a mobile communication module 505 provides a general communication function of the mobile terminal 110.
- the mobile communication module 505 includes a terminal switching request unit 505a and a terminal switching release request unit 505b, and performs terminal switching/terminal switching release between the telematics terminal 120 and the mobile terminal 110. That is, the mobile communication module 505 requests terminal switching or terminal switching release to the terminal switching server 170 according to signal received from the control unit 509.

And, the control unit 507 receives a key information inputted by the subscriber from a key input unit 513 and processes the key information. And, the control unit 507 receives a specific key information representing a terminal switching (or terminal switching release) command from the key input unit 513 and transmits a terminal switching (or terminal switching release) signal to the mobile communication module 505.
- the control unit 507 receives the terminal switching signal or terminal switching release signal from a sensor unit 515 and transmits the terminal switching signal or terminal switching release signal to the mobile communication module 505. That is, when the control unit 507 receives a starting activation signal from the sensor unit 515, the control unit 507 transmits the terminal switching signal to the mobile communication module 505. And, when the control unit 507 receives from the sensor unit 515 a sensor signal of stop of a vehicle during driving, trouble in the engine, stop of starting or existence of another passenger, the control unit 507 transmits the terminal switching release signal to the mobile communication module 505.
- the memory 509 includes EEPROM (Electrically Erasable and Programmable Read
- a flash memory stores various information including a map information, location of a vehicle, or RFID (Radio Frequency IDentification) or a telephone directory of the mobile terminal 110 of the subscriber.
- RFID Radio Frequency IDentification
- the display unit 511 has typically an LCD (Liquid Crystal Display), and displays various information by control of the control unit 507.
- the key input unit 513 includes various keys, for example a number key, a connection key or a menu key, and transmits to the control unit 517 a key information inputted by the subscriber.
- the key input unit 513 may be incorporated as a touch pad, and included in the display unit 511.
- the sensor unit 515 is connected to the electronic control unit mounted in the vehicle, and checks the state of the vehicle.
- the sensor unit 515 senses an overall signal of the vehicle, for example activation of starting, stop of the vehicle during driving, trouble in the engine or stop of starting, and transmits the signal to the control unit 507. And, when the sensor unit 515 senses a predetermined weight on a passenger seat other than a driver's seat, the sensor unit 515 transmits a sensor signal to the control unit 507. Further, when the sensor unit 515 senses a mobile terminal other than the driver's mobile terminal 110, the sensor unit 515 may transmit a sensor signal to the control unit 507. The sensing of another passenger is made by proximity reading using RFID.
- a sending/receiving unit 517 receives a decoded PCM signal from the control unit
- the sending/receiving unit 517 receives an input analog voice signal from the subscriber and transmits the analog voice signal to the control unit 509.
- the sending/receiving unit 517 may be connected to an external speaker and an external microphone of the vehicle.
- the above-mentioned present invention may be incorporated as a computer readable code in a computer readable medium.
- the computer readable medium includes all kinds of storage devices for storing data readable by a computer system.
- the computer readable medium is CD-ROM (Compact Disc Read Only Memory), RAM (Random Access Memory), ROM (Read Only Memory), a floppy disc, a hard disc or a magneto-optical disc.
- CD-ROM Compact Disc Read Only Memory
- RAM Random Access Memory
- ROM Read Only Memory
- floppy disc a floppy disc
- hard disc or a magneto-optical disc.
- the present invention facilitates terminal switching between a telematics terminal and a mobile terminal and automatically switches from the telematics terminal to the mobile terminal depending on another passenger to prevent another passenger from listening to a telephone conversation of a subscriber, thereby protecting privacy of the subscriber.
