## Title
Supporting a setup of a wireless connection

## Abstract

A BluetoothTM enabled device comprises a contact database arranged for storing BluetoothTM identifiers identifying other BluetoothTM enabled devices. This allows setting-up a BluetoothTM connection to another BluetoothTM enabled device based on a BluetoothTM identifier stored in this contact database and identifying the other BluetoothTM enabled device. New BluetoothTM identifiers identifying another BluetoothTM enabled device may be stored in the contact database of said first BluetoothTM enabled device.

## Background
FIELD OF THE INVENTION
The invention relates to a BluetoothTM enabled device and to methods for supporting in such a BluetoothTM enabled device a setup of a BluetoothTM connection. The invention relates equally to software program products storing software codes for supporting in a BluetoothTM enabled device a setup of a BluetoothTM connection.
BACKGROUND OF THE INVENTION
Various electronic devices support a communication via a BluetoothTM connection as specified in the “BLUETOOTH SPECIFICATION Version 2.0+EDR [vol 0]” 4 Nov. 2004.
The BluetoothTM specification contains information required to ensure that diverse electronic devices supporting the BluetoothTM wireless technology can communicate with each other worldwide via short-range radio links. The specification is aimed at providing a standard for low complexity low-cost wireless connections between portable and/or fixed devices, in particular devices which are located within a range of 10 meters to each other. An example for the employment of such a BluetoothTM short-range radio link is a wireless connection between a laptop and a printer, or between two mobile phones.
To each BluetoothTM enabled device, a unique identifier is associated, which is referred to for instance as BluetoothTM Identifier (BT-ID) or BluetoothTM Address. A BluetoothTM enabled device has to known the BT-ID of another BluetoothTM enabled device, in order to be able to setup a connection to this other BluetoothTM enabled device by means of a paging procedure.
Inquiry procedures enable a device to determine the BT-ID of all devices within its range to which a connection would be possible. In these procedures, a first device that wishes to establish a connection to some other device periodically transmits an inquiry message as broadcast message. The inquiry message has the form of an identity packet (ID packet) and might also include an indication of the type of devices that are to respond.
All devices that are willing to establish upon an inquiry a connection to some other device perform a scanning for such inquiry messages in an inquiry scan substate. The length of a scan period in which such a scanning is performed is denoted Tw—inquiry—scan and should lie in a range of 10.625 ms to 2.56 s. The scan interval between two consecutive scans is denoted Tinquiry scan and has a maximum value of 2.56 s. Alternatively, a continuous scanning could be carried out.
When a scanning device detects an inquiry message for which it was scanning, it will respond with a response message, more specifically with a Frequency Hop Synchronization (FHS) packet, carrying parameters of the device. These parameters comprise e.g. the BT-ID of the scanning device. However, in order to avoid a conflict when several devices are responding to an inquiry message at the same time, a further protocol is employed, before a response message is allowed to be transmitted. A similar problem may occur with colliding inquiring messages at a scanning device, when several devices are inquiring at the same time for other device to which they might establish a connection. According to this protocol, when a device detects an inquiry message, it generates a random number RAND between 0 and 1023. The device will then go back to sleep or to some other preceding state for the duration of a number of slots corresponding to the generated random number RAND. The duration of such a back-off is thus 0-0.64s. After the at least RAND time slots, the device will return to the inquiry scan substate and scan again for the same inquiry message detected before. Only when such a further inquiry message is received, the device turns into an inquiry response substate and transmits an FHS packet to the inquiring device, before returning again to the inquiry scan substate.
In between the transmissions of the inquiry message, the inquiring device scans for inquiry response messages. With the information in the received response messages it is then able to establish a connection to the responding device.
An additional problem with the setup time arises when two or more devices receive the ID packet. Then it is possible that during the inquiry procedure, the inquiring device receives multiple FSH packets and begins the paging process, which is used for establishing a connection with a specific device, which may at first be the ‘wrong’ device.
On the whole, setting up a BluetoothTM connection may take a considerable time.
In some situations, the time required for the setup may be particular annoying. For example, if a user of a first BluetoothTM enabled device desires to send some files to a second BluetoothTM enabled device belonging to a friend via a BluetoothTM connection, the user has to search the second device every time, even if a BluetoothTM connection has been used several times before between exactly these two devices, and if the user knows that the second device is near, that BluetoothTM is switched on in the second device and that the required services are available.
Usually, previously found devices are presented in a BluetoothTM search list. Thus, with some luck the user might find the desired device from this list. Nevertheless, in many cases, the user will have to perform a full search again.
Further, if there is a large number of BluetoothTM enabled devices in the environment during a search, it might be almost impossible for a user to find the desired one among all found devices, in particular if some of these devices are not recognizable to the user.
SUMMARY OF THE INVENTION
It is an object of the invention to enhance the setup of a BluetoothTM connection.
A BluetoothTM enabled device is proposed, which comprises a contact database arranged for storing BluetoothTM identifiers identifying other BluetoothTM enabled devices.
Moreover, a contact database for a BluetoothTM enabled device is proposed, which is arranged for storing BluetoothTM identifiers identifying other BluetoothTM enabled devices.
According to one aspect of the invention, moreover a first method for supporting in a first BluetoothTM enabled device a setup of a BluetoothTM connection is proposed. The method comprises setting-up a BluetoothTM connection to another BluetoothTM enabled device based on a BluetoothTM identifier stored in a contact database of the first BluetoothTM enabled device and identifying the other BluetoothTM enabled device.
For this aspect of the invention, moreover a first software program product is proposed, in which a software code for supporting in a first BluetoothTM enabled device a setup of a BluetoothTM connection is stored. When being executed by a processing unit of the first BluetoothTM enabled device, the software code realizes the first proposed first method.
According to another aspect of the invention, a second method for supporting in a first BluetoothTM enabled device a setup of a BluetoothTM connection is proposed. This method comprises storing a BluetoothTM identifier identifying another BluetoothTM enabled device in a contact database of the first BluetoothTM enabled device.
For this aspect of the invention, moreover a second software program product is proposed, in which a software code for supporting in a first BluetoothTM enabled device a setup of a BluetoothTM connection is stored. When being executed by a processing unit of the first BluetoothTM enabled device, this software code realizes the proposed second method.
The invention proceeds from the consideration that repeated searches by a first BluetoothTM enabled device for a particular other BluetoothTM enabled device can be avoided by storing its BT-ID permanently in the first BluetoothTM enabled device. It is therefore proposed that the contact database of a device is extended to allow storing BT-IDs, for example in a similar manner as phone numbers and email-addresses.
It is an advantage of the invention that it is suited to accelerate the setup of a BluetoothTM connection significantly. When sending a file via a BluetoothTM connection, for example, conventionally most of the time is spend in the search for BT-ID of the device that is to receive the file. Thus, with the invention, the entire communication can be speeded up significantly.
Further, the invention allows providing a user with a list only of known BluetoothTM enabled devices, which facilitates the user selection.
The processing means of the first BluetoothTM enabled device can be realized by hardware and/or software. They may include for instance a processor executing software code.
The software program products can be for instance a separate memory component, a memory for implementation in a BluetoothTM enabled device, a buffer used by a processor when executing the software code, etc.
In one embodiment of the invention, each BluetoothTM identifier is stored in the contact database in the scope of a respective contact card, for instance in a dedicated BT-field of a contact card. Such contact cards may be enabled for a respective contact person or for a respective device.
In one embodiment of the invention, the first proposed method may comprise searching in a contact database for stored BluetoothTM identifiers identifying other BluetoothTM enabled devices. The method may further comprise presenting to a user a list of entries associated in the contact database to BluetoothTM identifiers found in the search. The method may further comprise enabling a user to select of one of the presented entries for setting-up a BluetoothTM connection to another BluetoothTM enabled device, which other BluetoothTM enabled device is identified by a BluetoothTM identifier that is associated to the selected entry.
The listed entries may comprise for instance a contact person name, a device type and/or a device name. If the BT-ID of other BluetoothTM enabled devices is associated in the list to the name of the user and/or to a freely selected device name, the user does not have to know the name of the other BluetoothTM enabled device as used by the other BluetoothTM enabled device.
Once a listed entry has been selected by a user, a BluetoothTM connection may be set up to another BluetoothTM enabled device, which other BluetoothTM enabled device is identified by a BluetoothTM identifier that is associated to the selected entry.
In some cases, a plurality of BluetoothTM identifiers may be associated to an entry constituting a main entry. For example, for one contact person of whom the name is stored as a main entry, BluetoothTM identifiers for various devices may be stored. The names of these devices may then be stores as subentries in the contact database. In this case, the list may comprise a separate entry for each combination of the main entry and each associated subentry. Alternatively, the list may comprise at first only the main entries. Only in a next step, a list of subentries may be presented upon a user selection of the main entry. The user may then be enabled to select of one of the presented subentries for setting-up a BluetoothTM connection to another BluetoothTM enabled device, which other BluetoothTM enabled device is identified by a BluetoothTM identifier that is associated to the selected subentry.
In case no BluetoothTM identifier is found in the contact database during the search, the first method may further comprise performing an inquiry procedure for obtaining BluetoothTM identifiers of BluetoothTM enabled devices in the vicinity of the first BluetoothTM enabled device. A BluetoothTM enabled device for which a BluetoothTM identifier has been obtained may then be presented to a user. Finally, a BluetoothTM identifier that is associated to a BluetoothTM enabled device may be stored in the contact database upon a request by a user.
In one embodiment of the invention, also the proposed second method comprises performing an inquiry procedure for obtaining BluetoothTM identifiers, which identify BluetoothTM enabled devices located in the vicinity of the first BluetoothTM enabled device. The method may further comprise presenting a BluetoothTM enabled device for which a BluetoothTM identifier has been obtained to a user. The method may further comprise storing a BluetoothTM identifier that is associated to a BluetoothTM enabled device in the contact database upon a request by a user.
In this case, the inquiry procedure may also be initiated by a user, for example, though not exclusively, while having called a contact card from the contact database. A BluetoothTM identifier associated to a selected BluetoothTM enabled device may then be stored in the contact database as a part of the contact card.
After an inquiry procedure in either of the first method and the second method, the BluetoothTM enabled devices for which a BluetoothTM identifier has been obtained may be presented for instance one after the other to a user for storage or discarding. Alternatively, a list of all BluetoothTM enabled devices for which a BluetoothTM identifier has been obtained may be presented to a user, from which a user may select one for storage of the associated BluetoothTM identifier in the contact database. The user may also be prompted to enter a name that is to be associated in the contact database to this BluetoothTM identifier.
It has to be noted that BluetoothTM identifiers for storage may further be obtained in various other ways than in an inquiry procedure. For instance, when another BluetoothTM enabled device is trying to establish a BluetoothTM connection to the first BluetoothTM enabled device or has established a BluetoothTM connection to the first BluetoothTM enabled device, it will have provided its own BluetoothTM identifier to the first BluetoothTM enabled device. In this case, an option may be offered to a user of the first BluetoothTM enabled device to store a BluetoothTM identifier of the other BluetoothTM enabled device. In case the user requests thereupon a storage of the BluetoothTM identifier, the BluetoothTM identifier may be stored in the contact database.
Processing means of the proposed BluetoothTM enabled device may be adapted to carry out the steps of one or both of the presented methods and of any of the embodiments of the presented methods.
The invention may be implemented in any BluetoothTM enabled device, for example, though not exclusively, in mobile devices like mobile phones or laptops.
Other objects and features of the present invention will become apparent from the following detailed description considered in conjunction with the accompanying drawings. It is to be understood, however, that the drawings are designed solely for purposes of illustration and not as a definition of the limits of the invention, for which reference should be made to the appended claims. It should be further understood that the drawings are not drawn to scale and that they are merely intended to conceptually illustrate the structures and procedures described herein.



BRIEF DESCRIPTION OF THE FIGURES
FIG. 1 is a schematic block diagram of a system with a device according to an embodiment of the invention;
FIG. 2 is a flow chart illustrating a first operation in the system of FIG. 1; and
FIG. 3 is a flow chart illustrating a second operation in the system of FIG. 1.



DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a schematic block diagram of an exemplary system supporting facilitated and accelerated BluetoothTM communications in accordance with an embodiment of the invention.
The system comprises a BluetoothTM enabled device in which the invention is implemented. By way of example, the device is assumed to be a mobile phone 1. The system further comprises a plurality of other BluetoothTM enabled devices 2, 3, 4, 5, which are located in the vicinity of the mobile phone 1.
The mobile phone 1 comprises a conventional display 11, conventional user input means 12 and a conventional BluetoothTM interface BT-I/F 13. The input means 12 comprise softkeys which can be used for selecting options presented on the display 11 in specific Command Button Areas (CBA).
The mobile phone 1 further comprises a processor 20 which is adapted to run various software code components. The implemented software code components include a BT selection component 21 and a BT search component 22. The mobile phone 1 further comprises a memory 30. The processor 20 is adapted to access the display 11, the input means 12, the BluetoothTM interface 13 and the memory 30.
The memory 30 stores a contact database 31. The contact database 31 is designed to include a plurality of electronic visiting cards (vCard) 32 and a plurality of other contact cards 33.
The vCard 32 may be enhanced conventional vCards. Each vCard 32 may comprise fields for the name of a contact person and for various other information, like phone numbers of this contact person, etc. According to an embodiment of the invention, the vCards 32 comprise moreover additional BT-fields for storing BluetoothTM related information. Each BT-field may comprise a BT-ID and an optional device name or type. For instance, in a vCard for a contact person ‘A’, a first BT-field may comprise a first BT-ID ‘a’ and the device name ‘mobile phone’, while a second BT-field may comprise a second BT-ID ‘b’ and the device name ‘laptop’. In a vCard for a contact person ‘B’, a single BT-field may comprise a BT-ID ‘c’ and the device name ‘mobile phone’. In a vCard for a contact person ‘B’, a single BT-field may comprise a BT-ID ‘d’ and the device name ‘mobile phone’, etc.
The other contact cards 33 may be provided for contact information for devices which are not associated to a particular contact person. Each contact card 33 comprises at least a field for a device name and a BT-field for a BT-ID of the device. For instance, for a first printer, a first contact card may comprise as a device name the entry ‘printer X’ and a BT-ID ‘x’, while for another printer, another contact card may comprise as a device name the entry ‘printer Y’ and a BT-ID ‘y’.
The other BT enabled devices may comprise for instance a mobile phone 2 with BT-ID ‘a’ of user ‘A’, a laptop 3 with BT-ID ‘b’ of user ‘A’, a printer ‘X’ 4 with BT-ID ‘x’, and various other, unknown BluetoothTM enabled devices. Each of these BluetoothTM enabled devices is provided with a respective Bluetooth interface 41, 42, 43, 44.
A first operation in the system of FIG. 1 will now be described with reference to FIG. 2. FIG. 2 is a flow chart illustrating a selection procedure performed by the BT selection component 21 of mobile device 1.
A user of mobile phone 1 wants to send a file using a Bluetooth connection and selects a corresponding option using the input means 12. The user might want to send the file for example to a friend for further use or to a printer for a printout.
The BT selection component 21 detects that a user requests a BluetoothTM connection, for instance for sending a file (step 101).
It searches thereupon in the contact database 31, and more specifically in the BT-fields of all available vCards 32 and of all available contact cards 33, for stored BT-ID entries (step 102). The search of step 102 could also be initiated by a search procedure, as will be explained further below with reference to FIG. 3. Therefore, step 101 is indicated with dashed lines.
In case no BT-ID entry is found (step 103), the BT selection component 21 causes the BT search component 22 to start a search procedure, which will be described further below with reference to FIG. 3.
In case at least one BT-ID entry is found (step 103), a list is presented to the user of mobile phone 1 on the display 11 (step 104). The list comprises for each BT-ID entry found in the vCards 32 the contact person name and the device name or device names that are associated in the vCard to the found BT-IDs. The list comprises for each BT-ID entry found in the contact cards 33 the device name that is associated in the contact card to the found BT-ID. The list may thus comprise for example the entries ‘user A, mobile phone’, ‘user A, laptop’, ‘user B, mobile phone’, ‘user C, mobile phone’, ‘printer X’ and ‘printer Y’. In addition, the BT selection component 21 presents on the display 11 a ‘selection’ option in a first CBA and a ‘search’ option in a second CBA. Either option may be selected with a respectively associated softkey of the input means 12.
The user may now mark one device in the displayed list and use the ‘selection’ option for setting up a BluetoothTM connection to the marked device.
In case the user does not select one of the devices in the list for a BluetoothTM connection (step 105), but selects the ‘BT-search’ option (step 106), for instance because the user does not find a desired device in the list, the BT selection component 21 causes the BT search component 22 to start a search procedure, which will be described later on with reference to FIG. 3.
In case the user uses the ‘selection’ option for one of the indicated devices in the list (step 105), the BT selection component 21 tries to establish a BluetoothTM connection with the selected device (step 107). The user knows devices 2, 3 and 4 to be in the vicinity and selects therefore one of these devices.
In case the BluetoothTM connection could be established successfully (step 108), it may now be used for a BluetoothTM, for instance for transmitting a file to the selected device (step 109).
In case the BluetoothTM connection could not be established successfully (step 108), for example because the selected device is currently not located in the vicinity, the BT selection component 21 displays an error message on the display 11 (step 110).
It is to be noted that in the above example for step 104, the list could alternatively comprise only the main entries ‘user A’, ‘user B’, ‘user C’, ‘printer’. In an intermediate step, the user could then select one of these entries, upon which subentries are presented, if any. For example, upon selection of entry ‘user A’, a list with the subentries ‘mobile phone’ and ‘laptop’ would be presented, from which the user may now chose (step 105). Upon selection of entry ‘user B’, either a single subentry ‘mobile phone’ could be presented, or the procedure could proceed immediately with step 105.
A second operation in the system of FIG. 1 will now be described with reference to FIG. 3. FIG. 3 is a flow chart illustrating the search procedure mentioned above and performed by the BT search component 22.
The menu of the mobile phone 1 enables a user to initiate a BluetoothTM search. For instance, while the user is viewing a vCard that is available for a particular contact person, and a BT-field of the vCard is active, a CBA option ‘BT search’ may be presented to a user on the display 11. The option ‘BT search’ may then be selected by an associated softkey of the input means 12 for initiating BluetoothTM search.
In case the BT search component 22 detects that a user initiated a BluetoothTM search, for example by selecting a ‘BT search’ option (step 201), the BT search component 22 performs a conventional inquiry procedure for all BT enabled device in the vicinity, as described above (step 202). It has to be noted that the inquiry procedure may also be initiated by the BT selection component 21 during a selection procedure described with reference to FIG. 2, namely in step 103 or step 106. Therefore step 201 is indicated with dashed lines.
The BT search component 22 presents a list with all BluetoothTM enabled devices found in the inquiry procedure on the display 11. The list may comprise for instance the respective device type and/or a device name selected by the user of the device. In addition, it offers an ‘add to contact’ option in a CBA on the display 11.
When the user marks one of the BluetoothTM enabled devices in the displayed list and selects the ‘add to contact’ option by an associated softkey (step 204), the BT search component 22 adds the BT-ID corresponding to the selected BluetoothTM enabled device to the BT-field of a vCard 32 or a contact card 33 (step 205).
The user may add a device name to the vCard 32 or to the contact card 33, respectively, for instance before the search procedure. In case no device name is entered before the search, a device name and/or a device type received by the respective device in the search (step 202) can be employed provisionally and be amended by the user as desired. Further, in case the search procedure is not started proceeding from a displayed vCard 32 or contact card 33, for example because the search is initiated by the BT selection component 21, the user may first be asked whether the BT-ID that is associated to the selected device is to be added to a vCard 32 or to a contact card 33.
Once the BT-ID and any other desired information has been added in the contact database 30, the BT search component 22 causes the BT selection component 22 to start a selection procedure presented with reference to FIG. 2—starting off with step 102. In this procedure, the updated list of BluetoothTM enabled devices with available BT-IDs is presented to a user. The user may then select the correct BluetoothTM enabled device from the list.
It is to be understood that in addition, a user may be enabled to enter a known BT-ID manually to a vCard 32 or to a contact card 33. Further, a BT-ID could be transmitted, for instance via Infrared or via a short message service (SMS), in the scope of a vCard from one device to the other. Further, an option to store a BT-ID of another device 2, 3, 4, 5 in a contact card or vCard could be offered automatically to a user, whenever such another device 2, 3, 4, 5 is trying to create or has already created a BluetoothTM connection to the mobile phone 1, for example in order to transmit a file to the mobile phone 1. FIG. 3 indicates the latter option (step 301) followed by a possible user selection (step 302) with dashed lines. It has to be noted that in this case, the selection procedure should rather not be called upon the storage in step 205.
With the presented methods, a user may easily select known BluetoothTM enabled devices from a list, and also update the list in an easy manner. The overall time required for a Bluetooth communication is reduced.
While there have been shown and described and pointed out fundamental novel features of the invention as applied to preferred embodiments thereof, it will be understood that various omissions and substitutions and changes in the form and details of the devices and methods described may be made by those skilled in the art without departing from the spirit of the invention. For example, it is expressly intended that all combinations of those elements and/or method steps which perform substantially the same function in substantially the same way to achieve the same results are within the scope of the invention. Moreover, it should be recognized that structures and/or elements and/or method steps shown and/or described in connection with any disclosed form or embodiment of the invention may be incorporated in any other disclosed or described or suggested form or embodiment as a general matter of design choice. It is the intention, therefore, to be limited only as indicated by the scope of the claims appended hereto.
