CROSS REFERENCE TO RELATED APPLICATION

This is a reissue of U.S. patent application Ser. No. 11/652,175, filed on Jan. 10, 2007, now issued as U.S. Pat. No. 7,565,176, which is a divisional patent application of U.S. patent application Ser. No. 10/036,304 filed Dec. 28, 2001, now U.S. Pat. No. 7,184,797.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to communication devices capable of data and/or fax communication and, more particularly, to a system for displaying data transfer rates on a display.

2. Brief Description of Prior Developments

Traditional modems tend to indicate data transmission rates with blinking lights. Mobile communication devices, such as mobile phones, are now capable of acting as modems. Because these mobile communication devices include a more intrinsic display than those available on a traditional modem, there is an ability to portray more useful connection rate information to the user. In the past, Nokia Corp. has manufactured and sold mobile phones which indicate data transmission rates using graphical indicators.

There may be a desire by a first type of user to provide this communication rate information in an alphanumeric form. However, a second type of user might be overwhelmed by the technical nature of the information if communicated in an alphanumeric form. For such second type of user, a graphical display format, such as in the Nokia Corp. mobile phones, might be preferred. For a third type of user, there might be a desire to not display the data transfer rate at all. There is a desire to provide a system which can accommodate at least two and perhaps all three types of these users.

SUMMARY OF THE INVENTION

In accordance with one aspect of the present invention, a device for displaying data transfer rates on a display is provided. The device includes a system for displaying the transfer rates in an alphanumeric mode or an alternative graphics mode; and a system for switching between displaying the transfer rates in the alphanumeric mode and the graphics mode.

In accordance with another aspect of the present invention, a mobile radio communication device is provided having a display and a transceiver for transmitting and receiving data. The improvement comprises means for displaying a data transfer rate of data with the transceiver on the display in an alphanumeric format.

In accordance with another aspect of the present invention, a mobile radio communication device is provided comprising a transceiver, a controller coupled to the transceiver, and a display. The display is coupled to the controller. The controller is adapted to display on the display an indication of a data transfer rate of data by the transceiver. The communication device further comprises a system for inactivating display of the data transfer rate on the display while the transceiver is transmitting or receiving the data.

In accordance with one method of the present invention, a method of displaying a data transfer rate on a display is provided comprising steps of selecting, by a user, a data transfer rate display mode from a plurality of data transfer rate display modes; and displaying the data transfer rate on the display based upon the selected data transfer rate display mode.

The method and screens illustrated in FIG. 4 is only one type of method that could be employed to change the data transfer rate illustration mode. In an alternate embodiment, any suitable type of menus or screens for the user to select or changed the data transfer rate illustration mode could be provided.

In the embodiment shown in FIG. 4, the data rate indicators screen 80 includes a third data transfer rate illustration mode; an OFF or NONE mode. This type of mode prevents the data transfer rate from being displayed. The user can select the OFF mode. If the OFF mode is selected, then the data transfer rate indications 34 and/or 52 will not be displayed on the display 14 during data transfer. Thus, the user can select to turn the displaying feature of the data transfer rate ON or OFF.

The method and screens illustrated in FIG. 4 are generally intended to be used while the phone 10 is not in active communication with the base station 9. Referring now also to FIG. 5, a series of menus displayed on the display 14 for changing the data transfer rate display mode while the phone 10 is in active communication with the base station 9 is shown. When the phone 10 is in active communication with the base station 9, the control indicator section 28 of the display 14 does not list the menu function, but instead lists an “options” function.

The method and screens illustrated in FIG. 5 is only one type of method that could be employed to change the data transfer rate illustration mode while the phone 10 is in active communication with the base station 9. In an alternate embodiment, any suitable type of menus or screens for the user to select or changed the data transfer rate illustration mode while the phone 10 is in active communication with the base station 9 could be provided. For example, in one type of alternate embodiment, during active communication with the base station the display 14 could comprise the “Menu” descriptor for the control indicator section 27 as shown in FIG. 1 and, the menus and screens illustrated in FIG. 4 could be used. Thus, in this alternate embodiment, the method illustrated in FIG. 5 might not be used and the method illustrated in FIG. 4 might be used for both situations; the first situation of when the phone is in active communication with the base station and, the second situation of when the phone is not in active communication with the base station. In alternate embodiments, the phone 10 could be adapted to allow the change in the data transfer rate illustration mode to be made only while the phone is in active communication with the base station, or only while the phone is not in active communication with the base station.

Referring now also to FIGS. 6A, 6B and 6C, an alternate. embodiment of the graphical display mode is shown. In this alternate embodiment, the graphical indicator 90 comprises a plurality of slanted blocks 92. The blocks 92 comprise a darkened center or a non-darkened center. The totality of the blocks (six in the embodiment shown) graphically indicate a maximum transmission rate between the phone 10 and the base station 9. The number of blocks having a darkened center indicate a percentage of the maximum transmission rate actually being used to transmit data from the phone 10 to the base station 9. In the illustration shown in FIG. 6A, three of the six blocks 92 have a darkened center. Thus, in the example illustrated, the phone 10 is transmitting at a data transfer rate of about fifty percent of its maximum transmission rate. The number of blocks having a darkened center and a non-darkened center will increase and decrease as the actual data transfer rate of transmitting data from the phone 10 to the base station 9 increases and decreases.

The graphical indicator 94 comprises a plurality of slanted blocks 96. However, the slanted blocks 96 are slanted in an opposite direction relative to the slanted blocks 92. The blocks 96 comprise a darkened center or a non-darkened center. The darkened and non-darkened centers of the blocks 96 function the same way as the blocks 92 to indicate the actual reception rate versus maximum reception rate of data with the phone. Use of slanted blocks 92, 96 can allow for a greater plurality of indicators in each line. Although only six blocks are shown in each line, if the width of each line is diminished, more than six blocks can be provided.

FIG. 6A generally illustrates data being transmitted and received by the phone 10 at the same time. FIG. 6B generally illustrates transmitting of data by the phone 10 without data being received by the phone at the same time. FIGS. 6C generally illustrates receiving of data by the phone without data being transmitted by the phone at the same time. In the embodiment shown, the blocks 92 darken from left to right and the blocks 96 darken from right to left. However, they could darken in the same direction.

The present invention provides a mechanism whereby the user may select the type of data transmission rate display most appropriate for them. This mechanism also allows the user to shut OFF all data transmission rate displays, in view the standard in-call user interface using active data (or fax) calls. In the alphanumeric display mode, numerical data rates can indicate to the users their current data rate in exact numbers. However, for some less technical users, this information may be overwhelming. Graphical data indicators, on the other hand, are less intimidating for the user, but do not give exact information about the current data rate. Instead, they only provide information about where the current rate falls in relation to the peak rate. The present invention allows the user to choose the display mode based upon their own level of technical information desired. This provides an advantage of greater flexibility and personalization of the telephone's operation for the specific user.

It should be understood that the foregoing description is only illustrative of the invention. Various alternatives and modifications can be devised by those skilled in the art without departing from the invention. Accordingly, the present invention is intended to embrace all such alternatives, modifications and variances which fall within the scope of the appended claims.
