Method for handling phone numbers in mobile station and mobile station

The invention relates to the method defined in the preamble of claim 1 for handling phone numbers in a mobile station and to the mobile station defined in the preamble of claim 6.

From the prior art it is known to store numbers and corresponding names or the like in mobile stations or their memory cards. A phone number and a corresponding text code are stored. A number can be dialled browsing either the numbers or the codes. As a call comes in to the mobile station, a text code is displayed.

The problem with the known devices is that there is no distinction between numbers as regards call reception. Only the name associated with the number can be seen.

An object of the invention is to eliminate the disadvantages described above.

The method according to the invention is characterised in what is expressed in claim 1. The apparatus according to the invention is characterised in what is expressed in claim 6. Preferred embodiments of the invention are presented in the sub-claims.

The invention relates to a method for handling phone numbers in a mobile station. According to the invention, numbers are handled in groups 1a, 1b, 1c which have different attributes 2a, 2b, 2c.

In an embodiment of the invention the attributes 2a, 2b, 2c are rights to generate a ringing tone 7, 8, 9, 10. In an operating mode, only a call belonging to a group which in that operating mode may call the mobile station will generate a ringing tone.

In an embodiment of the invention the attributes 2a, 2b, 2c are different ringing tones 7, 8, 9. The ringing tones are specific to groups, each indicating the type of a group.

In an embodiment of the invention the attributes 2a, 2b, 2c are symbols indicating a group 1a, 1b, 1c on the display of the mobile station. The symbols are specific to groups, each indicating the type of a group.

In an embodiment of the invention the symbols 19a representing the groups 1a, 1b, 1c on the mobile station's display are dynamic. Such a dynamic symbol 19a is e.g. a throbbing heart.

The invention also relates to a mobile station 18. In accordance with the invention it comprises a processor 11 for handling number groups and determining attributes and a memory 12 for storing number groups. Such a mobile station is possibly fully voice-controlled and thus requires no other input means.

According to an embodiment of the invention it also comprises an audio part 15 for producing a group-specific ringing tone.

According to an embodiment of the invention it also comprises a keypad 14 for entering and selecting numbers and number groups. This represents an ordinary basic model of a mobile station.

According to an embodiment of the invention it further comprises a display 13 for displaying the symbol 19a of a number group. This represents an ordinary mobile station having a display.

According to an embodiment of the invention it further comprises an IR link 16, 18b, 19b for loading the number group symbol 19a to the mobile station 18.

An advantage of the invention is that attributes are defined in a mobile station according to a number and its group. These attributes preferably are ringing tones and symbols characteristic to a group as well as other specifications in the mobile station.

The invention is described in more detail with reference to the accompanying drawing wherein <dl id="dl0001" compact="compact"><dt>Fig. 1</dt><dd>shows groups according to the invention,</dd><dt>Fig. 2</dt><dd>shows in the form of flow diagram the method according to the invention,</dd><dt>Fig. 3</dt><dd>shows in the form of block diagram the essential elements of an apparatus according to the invention,</dd><dt>Fig. 4</dt><dd>shows the transfer of a group symbol according to the invention to a mobile station,</dd><dt>Fig. 5</dt><dd>shows in the form of flow diagram a method according to the invention for inputting numbers, and</dd><dt>Fig. 6</dt><dd>shows the structure of a called party's data element in the memory of the apparatus.</dd></dl>

Fig. 1 shows number groups according to the invention. Group 1a comprises home numbers, 1b office numbers, and lc customers' numbers. Group attributes 2a, 2b, 2c are shown on the left-hand side of the group tables 1a, 1b, 1c. The groups contain numbers 3a, 3b, 3c.

Fig. 2 shows in the form of flow diagram the method according to the invention as regards the indication of an incoming call. As a call arrives 4 in a mobile station, the network provides the caller's number. The mobile station checks 5 whether the caller's number is included in a group. This is indicated such that a group code is associated in the memory with a number belonging to a group. If the caller's number belongs to a group, operation branches 6 according to the group number and a ringing tone 7, 8, 9 is generated according to the group. If the caller's number does not belong to any group, a standard ringing tone 10 is generated.

Fig. 3 shows in the form of block diagram essential parts of a mobile station according to the invention. A processor 11 executes in the memory 12 a program which includes a function for making groups. A group symbol is displayed on the display 13, numbers and groups are input on the keyboard 14, and a group-specific ringing tone is generated in the audio part 15. The group symbol can be loaded via an infrared (IR) link. The elements are interconnected through an internal communication bus 17 in the mobile station.

Fig. 4 shows the transfer of a group symbol 19a according to the invention in the form of bitmap 18a from a microcomputer 18 to a mobile station 19 via an IR link 18b, 19b. The hearts 18a, 19a shown in this Figure represent the family and friends symbol and they are created on the large display of the microcomputer 18. The mobile station's 19 display is smaller and thus the heart symbol 18a, 19a is also shown smaller.

Let us consider by way of example how a group symbol 19a is produced on a mobile station 19. Preferably the group symbol 19a is drawn up as a bitmap 18a on a microcomputer 18 using a drawing program. When finished, the bitmap 18a is transferred via an IR link 16, 18b, 19b from the microcomputer 18 to the mobile station 19. The microcomputer's IR transmitter 18b sends the information in the form of modulated light to the mobile station's IR receiver 19b. In the mobile station 19 the bitmap 18a is associated with a certain group la, 1b, lc as group symbol. In advanced mobile stations the bitmap can be created using the apparatus' own software and keypad.

The group symbol is e.g. a heart, a happy/sad face or a stick figure. The group symbol is static or dynamically changing, comprising several images. The group ringing tone is advantageously created using a microcomputer 18 and sent via a link to a mobile station 19. Different ringing tones include e.g. beeps of various durations and musical melodies.

As a second example, let us consider a call from home to mobile station 19. A call is made from the mobile station user's home to the mobile station so that the mobile station 19 detects on the basis of the caller's number that the call is coming from home. The mobile station's display possibly shows the name associated with the number but additionally, in the manner according to the invention, the display also shows a group symbol, e.g. a heart 19a, and a group-specific ringing tone is sounded. So, the user knows even without looking at the apparatus, on the basis of the ringing tone, that the call is coming from the group in question, e.g. the family numbers group la. The ringing tone may thus be softer and melodic, representing a family matter, whereas a more traditional ringing tone is used for business matters.

Fig. 5 illustrates how numbers are input in groups in a manner according to the invention. First, a number saving mode is selected 20 using the push-buttons of the mobile station. Then, a number is selected 21 using the keypad and the selection is advantageously terminated by pressing a certain function key. A name is selected 22 and the selection is terminated in the same manner. A group code is selected, which preferably is an ordinal number. The ordinal number can advantageously be seen on the selection list of number groups which can be shown on the display. The data input are saved 24 by pressing a certain function key. A question is displayed on the display of the mobile station regarding the saving of additional numbers 25. If the answer is affirmative, the procedure returns to step 21 in which a number is selected. If the answer is negative, the saving mode is terminated.

Fig. 6 shows the structure of a table element for storing numbers and associated data in the memory of the apparatus. The table element comprises the called party's and/or caller's phone number 26, a name 27 and a group code 28. The phone number 26 advantageously comprises dialled digits fed to the mobile network, the name 27 alphabetical characters and the group code 28 one character only.

The groups may include e.g. VIPs, business, family, friends, etc. Advantageously the user creates the groups by means of the keypad and a menu.

The user may also define the attributes of the mobile station 19 such that only calls belonging to certain groups la, 1b, 1c will generate a ringing tone on the mobile station 19 during an important meeting, for example. In normal operating mode, numbers that do not belong to any group will generate the standard ringing tone.

The invention is not limited to the embodiments described above but many modifications are possible within the scope of the inventional idea defined by the claims set forth below.
