The following specification particularly describes the invention and the manner in which it is to be performed:
1 5 DEC 2006
The present invention relates to a mobile communications device.
This invention relates to a method of presenting menu information, relating to the operation of an accessory unit is used with a base unit. The invention also relates to a base unit and an accessory unit suitable for such use. For example, the base unit may be a mobile phone.
BACKGROUND OF THE INVENTION
Devices such as mobile phones have user interfaces, which allow their users to receive information relating to the status of the device. For example, the user interface may present such information in the form of a menu of available options, which allows the user to scroll through a list of headings, each of which may provide access to a list of sub-headings or available features, eventually selecting a desired feature. Such devices are commonly used with accessory devices which have no user interface.
There is therefore a need for a system which allows a user to select operating features of an accessory devices, through a menu structure presented on a user interface of a base device.
Advantageously, the base device should be able to support a range of accessory devices, including accessory devices which have not been conceived of when the base.device is designed.
W098/00993 discloses a method and a device for handling user menu
information in a mobile telephone. The mobile telephone stores at least
one standard menu. When an accessory is connected to the mobile
it can send a signal selecting a standard menu and
including data for adaptation of the standard menu.
For example, it may be preferable to include text which
identifies the type of accessory in use.
5 In devices such as mobile telephones, it is a
constant concern to minimise the size and weight of the device. This means that it is desirable to minimise the memory usage requirements of such devices. It is therefore desirable to avoid the need to store standard 10 menu structures, as described above with reference to the prior art. SUMMARY OF THE INVENTION
According to aspects of the invention., there are provided ba.se- devices, accessories, and methods of
15 operation of accessories in combination with base
devices.! A base device is able to support an interface updating protocol. An accessory is able to operate the same protocol. When the accessory is connected to the base device, the base device interface can provide the
20 user with an interface which allows him to control operating features of the accessory.
Preferably, the base device is a mobile phone. Preferably, the interface of the base device includes a display, which lists available operating features in a
25 menu structure, and a user input means, for example in the form of a keyboard.
In preferred embodiments of the invention, all menus, relating to the accessory, are stored dynamically within the base device. Thus, there is no
3 0 permanently available menu structure stored within the base device. Rather, when an accessory is first connected to a base device, a first menu is sent from the accessory to the base device. The menu is displayed for user selection. When the user has made a
35 selection, a sub-menu may be sent from the accessory to
WO 00/45571 PCT/EP00/00507
the base device and displayed. When the user has made a selection from the sub-menu, a control signal is returned to the accessory, but information relating to the sub-menu may no longer be stored in the base 5 device.
Advantageously, therefore, all subsequently developed accessories can be made compatible with existing base devices, by incorporation therein of suitable routines in the selected interface updating
Moreover, the use of dynamic storage of the menu items within the base device means that the requirement for usage of memory within the base device is greatly reduced.
15 Preferably, communications between the base device
and the accessories take place using the well-known AT protocol. This has the advantage that, when the base device is" a computing device, such as a hand-held computer, or PDA (personal digital assistant), which
20 will need to be able to support this protocol for other reasons, there will be no additional requirement for protocol support.
Although the AT protocol is known for controlling modems when they are connected to computers, the
25 preferred embodiments of this invention use the AT
protocol for controlling accessories other then modems. In particular, although the use of the AT protocol is known in computers for controlling modems, that is a wired accessory which connects the computer to a
30 network, the present invention contemplates the use of the AT protocol in a radio communications device for controlling a non-wired accessory that is an accessory which relates to the radio communications. For example, the non-wired accessory may use or control or
35 be controlled by or retransmit signals transmitted over
the radio communications link of the radio communications device. BRIEF DESCRIPTION OF/E?RAWTNGS
Figure 1 shows a telephone and accessory in 5 accordance with the invention.
Figure 2 is a block schematic diagram of the devices of Figure 1.
Figure 3 is a flow chart showing a first exemplary
operation in accordance with the invention.
10 Figure 4 is a flow chart showing a second
exemplary operation in accordance with the invention. DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Figure 1 shows a base device, in this case a mobile phone 2, having an accessory, in this case a
15 silent alerter 4, connected thereto, while Figure 2 is a block schematic diagram of the functional elements of the combination.
It will be appreciated that the illustration of a mobile phone and a silent alerter is only exemplary.
20 The base device can be any device which allows user
interaction. For example, it may advantageously be a computing device, such as a PDA (personal digital assistant), palm-top computer, or communicator, with computing and radio communications functions. Further,
25 the accessory could be any device intended to work with the base device, which in use of the invention does not require its own user interface. For example, the accessory could be a FM-radio receiver, a wireless headset, an electronic dictionary/translator, or a
3 0 device which connects to a radio communications device to act as a web-browser using the Wireless Application Protocol.
Moreover, although there is illustrated only a single accessory, two or more such accessories can be
connected at any time.
The phone 2 has a socket 6, while the alerter 4
has a matching plug-in connector 8 which allows it to
be connected to the phone.
5 The phone 2 has a display 10, for example in the
form of an LCD, for displaying information to a user. As will be described in more detail below, the displayed information can include a menu of available phone features.
10 Further, the phone has a keypad 12, by means of
which the user can input information to the phone. As is conventional, the keypad 12 includes numeric keys 14 and function, keys 16. The function keys allow the user to scroll through items in a menu displayed on the LCD
15 10, and allow the user to select an item from such a menu for activation.
It will be appreciated that the description of a user interface with a display and a keypad is purely exemplary. For example, the user interface may take
20 the form of a voice synthesizer output and a voice recognition input.
As is conventional, the phone has a memory 14 which stores menu information relating to features of the phone 2. Thus, when a phone is first switched on,
25 a first menu of available functions may be presented to the user. Selection of an item from that list may produce a sub-menu, which may contain specific features and/or further sub-menu headings.
However, in accordance with the invention, the
3 0 phone is also able to provide, dynamically, menu
information relating to features of the alerter 4. This is achieved by providing both the phone and the alerter with means for supporting a designated protocol for exchanging the required information. In this case,
35 as is described in more detail below, the protocol
which is used is the well-known AT protocol.
All features of the phone 2 operate under the control of a central processor 18, and all features of the accessory 4, for example a motor 2 0 which causes 5 the device to vibrate, operate under the control of a central processor 22.
For as long as the phone 2 is switched on and the alerter 4 remains connected thereto, the phone will store in the memory 14 information relating to a menu
10 item which refers specifically to the alerter. Similarly, if there is more than one accessory connected to the phone, the phone will store in the memory 14 information relating to a menu item which refers specifically to each such accessory.
15 Then, one of the items in the phone"s menu can be
a heading "Additional Menus", for example. Selection of this item brings up a list of sub-menu headings, each relating to one accessory which is connected to the phone. Selection of one of those sub-menu headings
20 then brings up a further sub-menu containing a list of items relating to functions of that accessory. The list may contain specific features, or may contain further sub-menu headings.
When required, information relating to an
25 accessory function is thus available for display to the user, in the same way as information relating to functions of the phone. If the menu option is selected by the user, a signal is returned to the accessory, which can then either control the accessory as
30 required, or can send information relating to a sub¬menu of accessory functions.
However, to minimise the requirement to store data in the memory 14, data relating for example to sub¬menus of accessory functions are not stored in the
35 phone, but rather are supplied dynamically from the
accessory to the phone when required. For example, if a user selects an accessory function using the keypad, data relating to the required subsequent LCD display are transmitted at that time from the accessory to the 5 phone.
By contrast, the initial information about the presence of the accessory, available under the heading "Additional Menus", is preferably stored in the phone for as long as the accessory remains connected. This
10 is because data transmission speeds between the phone and the accessories are rather slow (for example 2.4 kbit/s), with the result that the appearance of the items on the "Additional Menus" list would be rather slow if there were several items connected and such
15 information was not stored in the phone but needed to be sent from the respective accessories.
In order to be able to provide this functionality, it is necessary that the phone and each accessory be able to support a common interface updating protocol.
20 As mentioned.,previously, the protocol used in the
illustrated embodiment of the invention is the AT
It is also necessary to define a number of
standard format commands, which allow messages to be
25 passed between the—phone and any accessory connected thereto.
The definition of the protcol, and of a number of commands^ means that a given accessory can be used to obtain the same functionality with any phone which
30 supports the same protocol. Moreover, it means that any accessory which supports the protocol can obtain the same functionality with a given phone. Thus, the user interface of a phone.can be used to control an accessory connected thereto, _eyen if the accessory is
35 one which had not been designed or even thought of at
the time of manufacture of the phone.
There will now be described in more detail the
commands which are available for communication between
the phone and accessories.
5 In particular, there is described here a method
which defines four commands which may be sent from an accessory to a phone, each command instructing the phone to create a particular type of display on its LCD", and "being sent from the accessory to the phone
10 with associated information which forms part of the
display. Further, the method defines three responses, also sometimes referred to herein as commands, which may be sent from the phone to the accessory, based on user inputs in operation of the menu system.
15 A first command, which is sent from accessory to
phone, is a Menu Creation command. This relates to the creation of a persistent menu item, namely an item which is to be stored in the memory 14 of the phone for as long as the accessory is connected and the phone is
20 switched on. As mentioned above, it is the item which appears under the "Additional Menus" heading.
The command has the defined parameter
25 When the -phone receives this command it must:
create the additional menu if it is not already present; and add an item with the text specified in the parameter
A second command, which is sent from accessory to
30 phone, is a Submenu Creation command. This relates to the creation of a dynamic submenu, namely an item which is to be stored in the memory 14 of the phone only when it is being displayed. A dynamic submenu must have a parent menu item, which can be either a persistent menu
35 item which appears under the "Additional Menus" heading
or another dynamic submenu.
The command has the defined parameters:
10 when the list is first presented to the user for his
