Description

Communication system and method for operating such a system

The present invention provides a communication system and communication system in which each communication device is capable of communicating with a communication network, wherein both communication devices comprise first and second communication devices connectable to each other via a data link for information transmission. It relates to a method of operation.

International Publication No. WO 02/089449 A2 discloses a radiotelephone system comprising a first and a second radiotelephone, such as a mobile phone and a car phone, in which the second radiotelephone is a first radiotelephone. When connected to the second wireless telephone may use the actual connection parameters and SIM information of the first wireless telephone to establish a connection to the communication network without performing the usual channel search procedures and the like. Therefore, the connection of the first wireless telephone to the communication network can be switched to the second wireless telephone.

Thus, for example, a user of a communication network that owns a mobile phone and a car can use his car in his vehicle instead of his mobile phone after switching the connection, but someone with the subscriber number of the mobile phone You can be contacted by

Similar wireless systems include portable wireless telephones equipped with the ability to communicate with each other using a local wireless connection such as a low powered radio frequency (LPRF) link, a Bluetooth connection, or other communication means such as an infrared link. It is known from WO 02/21867 A2, which relates to management. Through the wireless link, one wireless telephone is within the coverage of the wireless link function to enable one wireless telephone to perform the same function as the SIM of another wireless telephone is inserted into one wireless telephone by itself. Information may be obtained from a SIM included in the wireless telephone. Thus, a wireless telephone using the SIM information of another wireless telephone is regarded as the remaining telephone in the communication network since all calls made to the other wireless telephone are received by the wireless telephone using the information of the remaining wireless telephone. In addition, any calls made to one wireless telephone are billed by appearing to be made by the other wireless telephone. Moreover, it should be noted here that one wireless telephone can be used by more than one user each user has his own (portable) wireless telephone.

EP 0 406 985 B1 discloses a first mobile cellular wireless telephone and a second hand portable cellular which can be connected to the first mobile cellular wireless telephone via a fixed wired electrical data link, an optical data link, or a wireless data link. Related to cordless phones

When two wireless telephones are connected to each other, the first mobile cellular wireless telephone is in a subscriber number search form, that is, a number assignment module that is compatible with a subscriber identification module (SIM) of the second hand portable cellular wireless telephone. (number assignment module; NAM) but using the RF of the second hand portable cellular radio telephone The circuits are switched off. According to one particular embodiment information from the NAM of the second hand portable wireless telephone may be downloaded into the memory of the first mobile cellular wireless telephone. The microprocessor of the first mobile cellular radiotelephone coupled to the memory or the NAM of the second hand portable radiotelephone is configured to cause the first mobile cellular radiotelephone to employ identification information of the second hand portable cellular radiotelephone. 2 Use the NAM information of the hand portable wireless telephone.

In addition, both wireless telephones may be provided with RAM for variable data, such as speed dial codes, frequent source telephone numbers, or other data. In this case, the variable data stored in the RAM of the second hand portable wireless telephone can be downloaded into the RAM of the first mobile cellular wireless telephone and the first mobile cellular wireless telephone is identification information of the second hand portable wireless telephone. It can be used with the first mobile cellular radiotelephone after employing.

Furthermore, due to the Bluetooth SIM Access Protocol (SAP), when both wireless phones are within the Bluetooth range of less than 10 meters, one mobile wireless phone can remotely access the SIM card inserted in the other wireless phone. have. This feature is a specific Bluetooth profile standardized in a car working group under the Bluetooth Special Interest Group (BT SIG).

The main operations according to this particular Bluetooth profile are as follows: The first mobile radiotelephone is registered with identification information from a local SIM card in a cellular network, ie a wireless communication network. Both wireless telephones can be triggered automatically or manually in the so-called remote SIM mode when the second mobile radio telephone enters a range of less than approximately 10 meters (Bluetooth range). In this mode a first mobile radio phone with a local SIM card escapes the wireless communication network while the second mobile radio phone can access the SIM card of the first mobile radio remotely via a Bluetooth radio data link. . In addition, the first mobile radio telephone deactivates all functions related to wireless communication. In other words, the first mobile radio telephone deactivates its radio. Within this mode the second mobile radiotelephone uses the SIM information obtained through SIM access via Bluetooth to register with the same user identification information within the cellular network. Finally, the second mobile radio telephone becomes an active radio telephone but the first mobile radio telephone becomes inactive while the remote SIM mode is active.

Both remote telephones return to local mode when the remote SIM mode is suspended, in which case the first mobile radio telephone is now active again.

If the first mobile wireless phone is a mobile phone and the second mobile wireless phone is a car phone, a seamless "handle from mobile phone radio to car phone radio" when the user boards the vehicle without using two different SIM cards. Hand over ". Since the mobile phone becomes active again when the remote SIM mode is suspended, it is a problem, for example, when it is necessary to switch off either radio in the vicinity of patrol stations or other areas where explosive materials are handled. The reason for this is that in this case both wireless phones are returned to local mode and consequently the mobile phone is reactivated so that switching to the simple off state of the car phone does not switch all the phones to the off state. Because it does not. Thus, the mobile phone is not switched off at the same time as the car phone.

Another problem that may exist is the loss of received information when an active second mobile radio, such as a car phone, has less functionality than the first mobile radio, such as a mobile phone. The mobile phone may be capable of receiving SMS, MMS, calendar lists (vCal) and business cards, etc. but the car phone does not support such features. Therefore, the received information by these features can be lost. When a user of a first cordless phone that needs to use a second mobile cordless phone instead of a first mobile cordless phone needs to use a cordless phone built into a vehicle, the contact card, phonebook list, calendar information, stored in his or her mobile phone, Another problem exists when one wants to use his own user specific data in the form of voice text, notes and the like.

It is an object of the present invention to provide a communication system and a method of operating such a system that allows the use of an improved and convenient communication system.

This object is achieved by the communication system of claim 1 and the methods of claims 3, 8, 12 and 14. Improvements and developments of the invention are described in the respective dependent claims.

It includes a step.

In order to prevent information stored in the second communication device from being used without permission, access to personal information from the first communication device stored in the second communication device is broken by the first and second communication devices. If allowed, it is not allowed.

According to a preferred embodiment of the present invention, the personal information from the first communication device stored in the second communication device is determined from the other first communication device when the other first communication device is first connected to the second communication device. Will be replaced with your personal information. This is particularly useful when the second communication device is installed in a rental vehicle with a large number of customers. In this case, it is possible to make the rental vehicle related information permanently stored in the second communication device, but only when the same user uses the rental vehicle and the second communication device of the rental vehicle, user personal information is stored in a separate memory area. Stored within.

If the second communication device is built into a vehicle used by a group of people, such as a family with whom the family shares a vehicle or an office worker who uses the same company vehicle alternately, It would be advantageous if first personal information from the other first communication device was stored in the second communication device separately from other personal information of the other first communication devices when the first communication device is connected to the second communication device.

Whenever the first and second communication devices are connected to each other, the first and second communication devices are configured so that the personal information stored in the first communication device is the same personal information as the personal information stored in the second communication device.

Therefore, after the communication device (telephone) is used by another user with different personal preferences, each user first inputs his personal phone data (configuration, phone book list, etc.) and then the communication device You can choose your own personal phone data without having to reset it. As a result, by simply selecting the respective personal information stored for each logical communication device, the user may again employ the communication device (telephone) in the manner in which the user is using his or her phone number, or in a preferred configuration. It is possible.

According to a preferred embodiment of the present invention, the first communication device is connected to a second communication device assigned internally to one of the logical communication devices via a data link for information transmission, and the personal information of the first communication device. Is communicated to the second communication device as personal information related to the second communication device, and wherein the personal information transferred from the first communication device is used internally with the assigned logical communication device. Are stored in. Thus, each user who owns a suitable mobile phone has his or her personal telephone data (SIM, preferences, stored in the mobile phone via the data link) to make such data available to the second communication device in a convenient manner. Phonebook, etc.).

For the operation of a communication system, each communication device comprises first and second communication devices capable of communication with a communication network, wherein both communication devices are connectable to each other via a data link for information transmission. Is provided with the logical communication devices in the second communication device, a first communication device connected to the second communication device via the data link is assigned to one of the logical communication devices, and the first and second communication devices.

In either case, in other words, the transmission of data improves the reliability of data reception even if the data has been provided in advance or the data could not be processed or manipulated by the second communication device, Data loss is prevented especially when including less functionality than the first communication device.

Hereinafter, the present invention will be described in more detail in connection with the embodiments shown in the drawings.

1 is a block diagram schematically showing a communication system according to the present invention.

As shown in FIG. 1, a communication system according to the invention comprises first and second communication devices 11, 12, each of which is capable of communicating with a communication network 10.

)와 같은 제어 유닛(13), 상기 통신 네트워크(10)와의 통신용 무선 링크(15,15')를 확립하기 위한 무선(R.F.)부(14), 상기 제1 및 제2 통신 장치들의 접속용 데이터 링크(17)를 확립하기 위한 저전력 무선(LPRF)부(16), 및 사용자 인터페이스(18)를 포함한다. 각각의 통신 장치의 사용자 인터페이스(UI; 18)는 키패드, 턴 푸시 버튼, 조그 다이얼, 전용 제어 버튼(18'), 온/오프 스위치, 음성 인식 수단 등등과 같은 사용자 커맨드들의 입력 수단, 및 디스플레이 및 라우드스피커와 같은 출력 수단을 포함한다.Each of the first and second communication devices 11 and 12 may be a microprocessor (

Control unit 13, a radio (RF) unit 14 for establishing a radio link 15, 15 ′ for communication with the communication network 10, and data for connection of the first and second communication devices. A low power radio (LPRF) portion 16 for establishing a link 17, and a user interface 18. The user interface (UI) 18 of each communication device comprises a means for inputting and displaying user commands, such as a keypad, turn push button, jog dial, dedicated control button 18 ', on / off switch, voice recognition means, and the like; Output means such as loudspeakers.

Furthermore, the first communication device 11 may include other identification means suitable for identifying a dedicated communication device as a communication device of a dedicated subscriber, such as a subscriber identification module (SIM) card 19 or a number assignment module (NAM). Subscriber Identity Module (SIM) is provided. The first communication device 11 further includes a memory for storing user data, such as a phone book list, a contact card, calendar information, a short message service message or information, voice text, memo and the like. This memory may be part of the SIM card 19 and / or the memory 20 provided separately from the SIM card 19 in the communication device 11.

The second communication device generally includes a SIM card 19 and a memory (MEM I) 20 like the first communication device. However, when using the features of the remote SIM access profile, the second communication device 12 does not necessarily need its own subscriber identity module, because the second communication device 12 does not have SIM information. The first communication device 11 causes the data link 17 to acquire and establish a wireless communication link 15 ′ with the communication network 10 and to employ identification information of the first communication device 11. This is because the second communication device 12 may use the subscriber identification information of the first communication device 11 when the second communication device 12 is connected to the second communication device 12 through.

Furthermore, according to the present invention, the second communication device 12 has a dedicated memory area (MEM II) 21 for storing personal information obtained from the first communication device 11, and for example the control as a dedicated application unit. It includes dedicated comparator means 22, which can be included in the microprocessor of the unit 13.

According to the first embodiment of the present invention, the dedicated memory area 21 is a dedicated area for storing personal information or user data from one first communication device 11, in which case the dedicated memory area 21 is located within the dedicated memory area 21. The information and / or data stored is only accessible while each first communication device 11 is connected to the second communication device 12 via the data link 17. As soon as the data link 17 is interrupted, the dedicated memory area 21 is not allowed any access to the information stored therein.

When the other first communication device 11 is first connected, the dedicated memory area 21 is erased and new personal information obtained from such a new first communication device 11 is stored in this dedicated memory area 21. do.

According to another embodiment of the present invention, the dedicated memory area 21 is for storing personal information so that other parts of the dedicated memory area 21 can be used for the other first communication device 11. At least two separate parts.

In order to explain the operation of the communication system of the present invention, it is assumed that the first communication device 11 is a portable wireless telephone or a mobile telephone, but the second communication apparatus 12 is a car phone or a wireless telephone installed in a vehicle. However, the communication system of the present invention is not limited to such a scenario and includes all cases in which the second communication device 12 which can be used by the user more conveniently than the first communication device 11 can be used. For example, if a user owns two communication devices and one of them is convenient to carry, but the other is more convenient to use within the user's office, the user may have his second communication device (eg, Nokia). Even if you use your second communication device to use subscriber identification information of its first communication device via a communicator, the user can always use the user identification information of his first communication device (e.g., a small mobile phone). have.

In addition, in the following description, contact data is used as an example. There are many other possible data that can be manipulated in the same way. When the user carrying the mobile phone as the first communication device 11 rides in a vehicle equipped with a car phone set to be connected to another communication device via the data link 17 in the same manner as the user's mobile phone, The first and second communication devices 11, 12, in other words the mobile phone and the car phone, are connected to each other via the data link 17.

When a connection between both devices is first established, contact information contained in the mobile phone is copied from the mobile phone to the car and stored in the dedicated memory area 21. The data in this dedicated memory area 21 can only be obtained while the mobile phone from which the data is leaked is connected to the car phone.

While the mobile phone is connected to the car, the user can use the contact data of the mobile phone currently stored in the dedicated memory area 21 or the contact data of the car phone stored in the corresponding memory area 20. You can choose whether to use. The important point here is that only one data memory is selected by the user at a time. This may be for example a menu selection in the car phone user interface. The selection of the active data storage area is important because the selection of the active data storage area has a special meaning when the dedicated memory area 21 is active. In this case, all changes of the contact data are continuously synchronized between the communication devices 11, 12, that is to say the memories 21, 20 of the mobile phone and the car phone. Thus, when a contact is added using the car phone user interface 18, the resulting contact is stored in the dedicated memory area 21 and then automatically copied to the memory 20 of the mobile phone.

When the user gets out of the vehicle with his mobile phone, the data link 17 is terminated. As a result, the data in the car phone's dedicated memory area 21 is no longer available, but this data is not erased. In particular, it should be noted that the data in the dedicated memory area 21 can be used while the first communication device 11 from which data is leaked is not connected to the second communication device 12, ie the car. It is not.

When the same mobile phone is reconnected to the car via the data link 17 using the respective LPRF sections 16, the comparator means 22 of the control unit 13 has the same information in both memories. The data stored in the mobile phone is compared with the data stored in the specific memory area 21 of the car to check whether or not it is stored in (20, 21). If some of the information stored in the mobile phone is changed, only such changes are copied to the dedicated memory area 21 of the car phone. Thus, instead of copying all contact data from the mobile phone to the car, this data is only synchronized so that the data memories are then matched. Operation after synchronization continues as mentioned above.

When another user boards a vehicle with another mobile phone that can be connected to the car via data link 17, the microprocessor or control unit 13 of the car has priority over the mobile phone connected to the car. Check if it is connected. Therefore, according to the first embodiment of the present invention, the contact data of the new mobile phone is copied to the dedicated memory area 21 of the car so that the contact information leaked from the old mobile phone is erased and replaced with the contact information of the new mobile phone. do.

According to another embodiment of the invention, the dedicated portion of the dedicated memory area is such that the new mobile phone can be stored in another portion of the dedicated memory area 21 without the contact information being duly erased. Is assigned to.

In this case, it is not possible at all to use the contact data of the mobile phone not connected to the car.

Synchronization of the data to match the data of the mobile phone and the mobile phone stored in the car is performed in the same manner as mentioned above.

According to another embodiment of the present invention, the second communication device comprises first physical communication devices 11 or SIM cards 19 to logical communication devices provided to the second communication device 12, respectively. To allow allocation. Specifically, the logical communication devices are stored in a dedicated memory area of the second communication device, such as a dedicated memory area 21, and all data associated with the communication device, such as a user preference, a phone book such as a phone book and the like. Include relevant data. In this way, the use of personalized multiple users of a single wireless telephone is allowed.

When a first communication device 11, for example a mobile phone, is connected to the second communication device 12, for example a car, via the data link 17, the mobile phone is connected to the second communication device 12, in other words It is assigned to one of the logical communication devices in the car. The corresponding phone data of the mobile phone, such as user preferences and phone book listings, are then automatically or correspondingly entered by the user to provide the user of the car phone with all the phone related data known from his own mobile phone. The second communication device 12, in other words the car phone, is transmitted over the data link in response to a command.

In addition, one SIM card 19 provided in one first communication device 11 and the same first communication device 11 or the first communication device 11 or the second communication device 12 and It is also possible to assign the same SIM card 19 to different logical communication devices. Thus, in order to allow each user to select his or her own preferences, a dedicated first communication device 11 or a mobile phone or second communication device 12, i. It is possible to share a local SIM card provided by users.

As assumed above, when the first communication device is a mobile phone and the second communication device 12 is a car phone, the present invention provides a plurality of mobile phones with different mobile phones and / or other phone data or preferred phone preferences. Allow users to use their car without any mistake. Each user does not have to adopt the car phone by exchanging SIM cards or resetting the car to adapt their car to their preferred phone preferences or the way they are used to use their mobile phone. Personal phone data may be provided, such as a SIM card, phone preferences, phone book and the like.

When the mobile telephone 11 is first connected to the car automatically via a data link or upon user request, all the telephone 11 related data is transmitted to the car. In the car phone, the mobile phone related data is assigned to a specific logical phone provided in the car phone. Each logical phone can then be automatically selected for further operation of the car to allow the user of the mobile phone to use the car in exactly the same way as his mobile phone.

When the mobile phone is connected to the car again, the corresponding logical phone containing all the mobile phone related data can be selected automatically or according to user requirements.

When another mobile phone of another user is first connected with the car phone, the other mobile phone is assigned to another logical phone within the car phone. In this case the operation of the system is exactly the same as mentioned above.

However, which logical phone should be used with a new mobile phone, i.e. a dedicated logical phone with a given preference or a new preference or with another (new) logical phone with no preference or with a default preference? It is also possible to inform the user of the connection of the new mobile phone to the car to determine. If another logical phone is to be used, personal data, in particular phone preferences, may be recovered from the new mobile phone or entered by the user.

Furthermore, the local SIM card 19 of the car phone 12 may be provided with other logic provided within the car phone 12 to enable other users of the car phone to use the car in other ways without having to use the mobile phone. Can be assigned to the phone. In this case, the phone preferences and the phonebook list must be entered via the user interface 18 of the second communication device. However, although it is possible to use the local SIM card 19 of the car 12, the personal information provided in the mobile phone 11 can be easily transferred to the car and also the local SIM card 19 in the car. It is also possible to enter personal information, ie phone preferences, contact data and the like, via a data link 17 established between the car phone and the mobile phone 11 for use with the.

Upon switching to the on state, the car phone enters the operating state of the last operating period. When the car phone is operated by user A using a local SIM card 19 and preference A (ie, local preferences) stored only within the car phone, the car phone is configured with the local SIM card 19 and preferences. A is used again to enter the same state and preferably notifies the user to confirm the selected operating state or to select another operating state. If the mobile phone is connected via the data link 17 such a configuration (remote configuration, ie it may or may not be stored in the car, but only a mobile phone out of which the configuration is leaked) is connected to the car. If the local SIM card 19 was last used with the preferences provided by the mobile phone to ensure that only those preferences (which can only be accessed while being set) are accessible, the car phone will return to the corresponding operating state. Attempt to enter. In this case the operating state is considered to be confirmed if the corresponding mobile phone is accessible via the data link 17. However, if the mobile phone is not available, the user is informed to select a suitable operating state, that is to say a suitable preference. When the car is finally used with the remote SIM card 19, the car phone 12 attempts to access each SIM card 19. When this connection is made successfully, the car phone operates with identification information according to each SIM card 19. If the connection is not successful, the user is informed to select a suitable state.

In either case, in other words, whether using a local SIM card 19 with local preferences, a local SIM card 19 with remote preferences, or a remote SIM card 19, the phone preferences are It may be entered or modified by the user via the car phone's user interface 18.

According to another embodiment of the present invention, the second communication device 12, such as a car phone, may be provided with a dedicated standby mode (either through manual selection using a menu of the user interface 18 or as a dedicated part of the user interface 18). can be selected via a stand-by button 18 '.

When the standby mode is selected, the connection between the first communication device 11 and the second communication device 12, that is, the data link 17 remains active, but the The radio 14 of the second communication device 12 is switched off so that the radio 14 and the radio 14 of the second communication device 12 are simultaneously switched off. Thus, it is possible to deactivate the radios 14 of both communication devices 11 and 12, but the data link 17 is located near a patrol station which is not allowed to use the communication devices. Within the regions it is particularly active to prevent the first communication device 11 from initiating establishing a radio link 15 for the communication network 10.

To prevent data loss when the second communication device 12 has less functionality than the first communication device 11, such as not supporting calendar or multimedia messaging service (MMS) features. The second communication device 12 may include the communication network 10 when the second communication device 12 is connected to the first communication device 11 and uses identification information of the first communication device 11. ) Transmits data received from the first communication device 11 via the data link 17. In this way the user always has all received data on his first communication device. This feature is particularly important when the second communication device cannot display or process the received data.

In this case, specific data is received by the second communication device 12 and transmitted to the first communication device 11 so that a user is immediately notified and the first communication device 11 is sent to the second communication device. It is preferable to be displayed to the user so as to select whether or not to access specific data by disconnecting from (12).

In this way data loss can be reliably prevented and the user can confirm the received information or data in the inbox as if the information had been received directly via the communication network 10. Thereafter, typical processing and / or manipulation of the received data may be performed in a conventional manner.
