Definitions

  • the present invention relates to the field of remote control of devices in networks.
  • the present invention is concerned with remotely controlling devices and data transmission from devices over wireless networks.
  • the present 3G mobile telephony systems have made wireless video telephony possible.
  • the communication terminal or terminal is generally used for face to face video recording and presentation between calling parties.
  • Each user has control of the outgoing video transmission from its terminal, and can decide what to show to the remote party.
  • current solutions for remote control are static, in that the terminal has to be configured for the particular system which it is intended to control. If, for instance, the user wants to control a remote surveillance system from a portable communication terminal, the terminal has to be pre-configured for the remote system services and how to access them before calling the system.
  • a general object of the invention is therefore to provide means for improved capabilities for remote control in video communications. Particularly, it is an object to provide means for remote video call control without requiring pre-configuration of the terminal.
  • this object is fulfilled by a method for remotely controlling a device from a communication mobile terminal through a telecommunication network, comprising the steps of:
  • the method comprises the step of transmitting said data message from said device as a text string.
  • said text string comprises remote menu content, comprising title data for one or more menu levels, and menu item data for one or more of said menu levels.
  • said menu item data comprises said action command and a label for said action.

  • the method comprises the step of transmitting said service request signal as a text string.
  • said device system is included in a remote mobile terminal.
  • said data message is an xml message.
  • said device system is a video system.
  • the method comprises the steps of:
  • the video system is devised to switch from transmitting said first image data to transmitting said second image data, upon receiving said action command.
  • the video system is devised to transmit said second image data in addition to said first image data, upon receiving said action command.
  • said first and second camera are comprised in a camera surveillance system.
  • said first and second camera are comprised in one and the same mobile terminal.
  • At least one of said first and second image data represent moving pictures.
  • At least one of said first and second image data represent real time video.
  • the method comprises the steps of:
  • said first video content data is video data for a first television station
  • said second video content data is video data for a second television station.
  • said device is a software supplier means in said telecommunication network
  • said data message includes information on a downloadable software item
  • the step of triggering said action initiates download of said software item from the software supplier means to the terminal through said telecommunication network.
  • the method comprises the steps of:
  • the method comprises the steps of:
  • a mobile communications terminal comprising radio signal transmitting and receiving means for mobile communication with a device, and a user control input, and comprising means for remotely controlling said device, including means for receiving a data message, comprising an action command to which said device system is responsive for performing a certain action, and means for triggering said action in the device by transmitting said action command to the device.
  • said means for receiving a data message is devised to receive data messages in the form of text strings.
  • said text string comprises remote menu content, comprising title data for one or more menu levels, menu item data for one or more of said menu levels, and an action command with an associated label, for at least one menu item

  • radio terminal or communication terminal also denoted terminal in short in this disclosure, includes all mobile equipment devised for radio communication with a radio station, which radio station also may be mobile terminal or e.g. a stationary base station. Consequently, the term radio terminal includes mobile telephones, pagers, communicators, electronic organisers, smartphones, PDA:s (Personal Digital Assistants), laptop computers, and DECT terminals (Digital Enhanced Cordless Telephony). Further, the present invention is equally applicable to stationary devices, and for radio transmission to and from stationary devices. Such stationary devices include e.g. desktop computers. Furthermore, it should be emphasised that the term comprising or comprises, when used in this description and in the appended claims to indicate included features, elements or steps, is in no way to be interpreted as excluding the presence of other features elements or steps than those expressly stated.
  • Fig. 1 illustrates in a schematic way how signals are transmitted between a radio terminal 100 and a video system 110, according to an embodiment of the invention.
  • Terminal 100 includes a display for presenting still and moving pictures to a terminal user.
  • connection has to be established between terminal 100 and video system 110.
  • terminal 110 is typically a mobile phone, whereas video system 200 may e.g. be another mobile phone, or a video service provider connected to a mobile telephony network, which terminal 110 is devised to access.
  • video system 110 may transmit video content 120 to terminal 100.
  • the video content may be live video data, or a video recording.
  • the video content 120 is received in terminal 100, for presentation on its display.
  • the user of terminal 100 may control the video system 110, e.g. for making adjustments or settings in the video system, or for controlling the video content 120 transmitted to terminal 100.
  • terminal 100 preferably transmits a service request signal 130 to video system 110.
  • video system 110 Upon receipt of service request signal 130, video system 110 transmits a data message 140 to terminal 100.
  • data message 140 may be transmitted together with video content 120, in which case the service request signal is not needed.
  • the communication starts with the transmission of the service request signal 140, before any video content is transmitted from video system 110 to terminal 100.
  • the received data message 140 comprises menu items for remote control of video system 110, which menu items are usable for building a menu structure in terminal 100.
  • the terminal user may see which type of services and possibilities that are available for remotely controlling the video system 110, by presenting them in the menu system on the terminal display. With this method, the user and his terminal 100 do not need to know anything about what is at the far end, nor how to access and control the services, and it can be presented in a way generic for that client.
  • the user enters the menu built up from the received data message 140.
  • the menu comprises one or more menu labels, and for each one or more labels there is an associated action command.
  • a certain action in the remote video system is triggered by selecting the appropriate menu label in the displayed menu.
  • the selection of a menu label in the remote control menu causes terminal 100 to transmit the associated action command 150 to video system 110.
  • action command signal 150 is received, responsive to which the action to which the command 150 is associated is carried out.
  • the desired action is to affect or change the video content sent to terminal 100.
  • video system 110 is therefore forced to send new or amended video content 160 to terminal 100, for presentation on the terminal display.
  • Fig. 2 illustrates schematically different ways of carrying out the invention.
  • a terminal 100 in the form of a mobile phone is used.
  • Mobile phone 100 is connectable by means of radio transmission to a base station 210 of a mobile telephony network 200.
  • One way of using the invention is to communicate with another mobile phone 230, through a base station 220 of network 200.
  • Terminal 230 then constitutes the video system, i.e. a device capable of providing video services to terminal 100, and which can be remotely controlled by terminal 100 to a certain extent, according to the invention.
  • mobile phones 100 and 230 may just as well be connected through different mobile networks, which networks are in turn communicatively connected to each other.
  • One example of such an embodiment comprises two Sony Ericsson z1010 radio terminals; terminal 100 and terminal 230.
  • the z1010 follows the 3G324m standard and supports the UserInputIndication in H.245.
  • the UserInputIndication protocol can be used for transmitting text between the clients of the terminals, through an information channel. This is e.g. used for handshaking in video calls, but may also be used for transmitting e.g. DTMF tones.
  • This information channel is parallel to the data channel on which e.g. video data is transmitted during a video call.
  • a remote menu may be distributed by using this protocol, preferably using the information channel.
  • the calling phone 100 is devised to send a service request signal, see 130 in Fig. 1, comprising a text string asking for what services the remote party offers and how to control them.
  • the text string may e.g. simply be a transmitted string "GetService”.
  • phone 130 Upon receiving the service request signal 130, phone 130 is devised to return an xml-styled response in a data message, see 140 of Fig. 1.
  • the xml text string thereof is interpreted by the client of the phone, and is further devised to build a menu for controlling phone 230 at the far end.
  • the service-providing phone 230 may transmit the data message with its text string without a preceding request from the service-receiving phone 100. From the received text the client of phone 100 can tell that the other party, i.e. phone 230, supports a Remote Menu Service. Since the client of phone 100 knows that type of service, it can continue to read the text in order to build the menu. The title of the menu is extracted with the help of the title tags.
  • the title can preferably be used as an entry in the actual menu structure to the remote menu.
  • An example of this is schematically illustrated in Figs 3-8.
  • Fig. 3 illustrates shows a display 300 of phone 100.
  • a picture 301 of a person operating the far end phone 230 is presented on display 300.
  • picture 301 is a video signal captured by a built-in camera in far end phone 230, and picture data for picture 301 is transmitted to phone 100 in a video call between the user of phone 100 and the user of phone 230.
  • User control means are included in phone 100, including buttons and/or a touch-sensitive display screen.
  • so called soft keys 302 are used, which indicate a function on display 300 and are selected by means of an associated key, joystick, or the like.
  • a centre soft key 303 is used to display a menu.
  • a data message comprising a text string with menu items has already been received in phone 100 from the remote phone 230.
  • the menu is built by the received menu items, where an item comprises a label and an action command.
  • the label is presented in the menu, whereas the action command is sent back as a text string to the remote end phone 230 to perform the action described by the label.
  • menu key 303 has been activated, whereupon a main menu 400 is presented on display 300.
  • Main menu 400 includes a number of titles for menu items, of which 402 and 403 are related to operation of phone 100.
  • a menu item title 401 for remote controlling is displayed, which may be selected to control remote phone 230.
  • the user of phone 100 uses a display control device, such as arrow keys or a jog ball, to move a selection indicator 404 to menu title 401, and e.g. a soft key 302 to select and trigger remote control.
  • Fig. 5 illustrates an example of a how a menu 500 under the main menu 400 may be built up and presented when menu title 401 is selected.
  • the received text string from phone 230 has been interpreted and used to control operating software of phone 100 to implement menu labels 501-503, which relate to remote control of far end phone 230.
  • selection indicator 404 By placing selection indicator 404 on e.g. menu label 501, and selecting that label, transmission of the associated action command "doCameraSwitch" is made to phone 230.
  • Fig. 6 illustrates the effect of selection of menu label 501.
  • Phone 230 includes, or is connected to, at least two cameras, and receipt of the transmitted action command causes phone 230 to send picture data from another camera than the camera sending the previous pictures.
  • a similar label and command may be used, where picture data from both the first and the second camera are transmitted, and subsequently presented in a split screen on display 300 of phone 100.
  • the camera switch command forces phone 230 to switch from transmitting pictures taken by a first camera towards the phone user, to transmitting pictures taken from a second camera on an opposite side of phone 230, aimed away from the user of phone 230, or vice versa.
  • Fig. 6 illustrates such a scenario, where the camera switch cause a picture 600 of a landscape, captured by a second camera of phone 230, is received in phone 100 and presented on display 300.
  • Fig. 7 illustrates again remote controlling menu 500, where instead menu label 502, zoom in, is selected.
  • Fig. 8 finally, illustrates how the selection of menu label 502 triggers transmission of a zoom in command to phone 230, where receipt of that command triggers the camera capturing picture 600 to zoom in.
  • the user of phone 100 may communicate more freely with the far end user controlling phone 230, by selecting to see the other user or to see what that other user sees. This kind of communication is more natural, as it is normal to choose for yourself what to look at.
  • a surveillance system 240 includes one or more cameras 241-243.
  • control surveillance system 240 may e.g. include camera switching, zooming in and out, panning, activation of night vision systems, etc.
  • surveillance system 240 is the video system, even though it does always have to capture and transmit moving pictures.
  • Video system 250 may be a switching system, taking in picture signals from a plurality of sources 251-253, such as online television stations, recorded movies, music videos, live cameras, chat rooms, and so on.
  • sources 251-253 such as online television stations, recorded movies, music videos, live cameras, chat rooms, and so on.
  • a menu can also comprise several sub-menus.
  • An example of a text string usable for building up such a menu, with submenus, is presented below.
  • a menu is provided where, in a first level, TV channels or movies are selectable labels, under which separate menus including different TV channels and different movies, respectively, are selectable.
  • such an embodiment is similar to a portal, from which a multitude of different video services may be reached.
  • the video system becomes very easy to handle, since a menu type which the phone user is familiar with is used.
  • the remote controlling does not necessarily have to relate to the picture sent back, such that it is perceivable by the user of phone 100.
  • the action command transmitted may e.g. be "record", whereby a certain live television show or a surveillance camera is set to record captured pictures to a recording medium in the video system, for instance for subsequent download to phone 100.
  • the actual meaning of the menu labels is not known to phone 100, it merely reacts upon selection of a certain label by transmitting the associated command to the video system.
  • that video system is also the video system from which the data message containing the text string with the menu items originally came from.
  • the data message containing the text string with the menu items is transmitted from one device, but are associated with address data to another device, to which action commands are sent upon selection of associated menu labels in the remote controlling menu.
  • a surveillance company is contracted to install surveillance equipment, typically cameras 241-243, but potentially also microphones, IR detectors, and so on, to monitor a certain object or area (not shown).
  • the surveillance company may also provide a service for remote control of the surveillance equipment, by transmitting a text message from a central communications device 250 to a communication terminal 100 of the user wanting to take part of surveillance data, typically the owner or caretaker of the object or area. From the received text message, a menu for remote control is automatically incorporated in the standard menu of terminal 100. For reasons of secrecy, the user may however want to have exclusive rights to see the data output from the surveillance equipment, or to control the equipment.
  • a local surveillance control box 244 is preferably installed on site at the object or area, connected to the surveillance equipment 241-243.
  • the action commands received in the text message from central communications device 250 are therefore associated with address data, preferably included in the received text message, to the local control bow 244. Selection of an action command therefore initiates transmission of the action command to the associated address, i.e. to the local control box 244, even though the text message was originally received from the central communications device, e.g. a server system as indicated by 250.
  • transmission of the action command may e.g. be devised to initiate transmission of surveillance data to the terminal 100, either live or recorded, or for instance to make adjustments in a surveillance setup. Such adjustments may e.g.
  • a data message preferably a text message
  • the data message includes information on a downloadable software item, and an associated action command for initiating download of that item by transmission of that action command to an associated address included in the data message.
  • the software item may e.g. be freeware from commercial enterprises, such as movie clips, in which case a menu item may have a title reflecting the name of a new movie, with different labels for downloading movie clips and for ordering the movie.
  • Another example is software items provided by the network operator, such as patches or new applications for installation in the terminal, e.g. for optimizing the performance of the terminal in the network or simply adapting the terminal to adjustments made in the network.
  • Fig. 9 describes the overall features of an embodiment of the present invention.
  • communicative connection is established between a first mobile terminal 100 and a device 110 in step 910.
  • terminal 100 receives a data message including a text string, preferably from device 110, comprising an action command for triggering an action in the device or elsewhere.
  • action command is transmitted to an address associated with the action command, e.g. device 110, in which an action corresponding to the command is taken.
  • Fig. 10 illustrates a more detailed embodiment of a method according to the invention, starting from step 1000, related to remote control of a video system.
  • connection is established, for instance by simple dialing by phone 100 to a video system 110.
  • video content is received in phone 100 over the established connection, which video content is displayed on phone 100.
  • the user of phone 100 transmits a service request signal to video system 110 in step 1003, preferably using a channel parallel to a data channel over which the video content was sent.
  • video system 110 sends back a data message comprising a text string in step 1004, preferably also over the channel parallel to the data channel.
  • step 1005 the text string is interpreted in terminal 100 by its operation software to extract menu items, including menu labels and related action commands, and in step 1006 a menu is built up from the extracted menu items, in phone 100.
  • the user browses the menu in step 1007 of phone 100, in which the remote control menu built up has now been included.
  • step 1008 a certain menu label is selected in phone 100, upon which the associated action command is automatically transmitted in step 1009.
  • transmission addresses relevant for the particular action commands were included in the received data message. Possibly, different addresses may be included for different action commands, alternatively only one address is transmitted in the data message, valid for all action commands of the data message.
  • the communication address of the sender of the data message is also used as the address data to which the action command is transmitted. Transmission is in this case made back to video system 1110.
  • video system 110 When video system 110 has received the action command, it performs the associated action, such as changing video content to be transmitted to phone 100 over the data channel, and in step 1010 the changed or added video content is received in phone 100 from video system 110, and shown on a display of phone 100, whereby the method ends at step 1011.
  • the basic problem behind the invention is that today, mobile phone clients have to be pre-configured for different services in order to control or access them on the remote side.
  • remote video call control the client just builds the menu structure transmitted in the xml-form, it does not need to know anything about the services.
  • the information of different services and how to control them are sent to the client as xml formatted text.
  • the text can e.g. be transferred between the parties by using a simple text protocol, e.g. T.140 or the Userlnputlndication in H.245 which is supported by all H.324 video conferencing clients. Consequently, an important feature of the invention is that the video system transmits a complete menu system with a label and a corresponding action command to the client.
  • the client can then easily integrate the information in its own menu structure and it does not need to know what type of services the other party serves.
  • the video system can for instance easily tell the client how to control its camera. A comparison can be the case where clients control cameras by using the H.281 Far end camera control protocol. Then both the client and server has to support H.281. By supporting remote video call control, this and other services can be enabled in both directions.
  • an ordinary communication channel may be used for communication purposes, whereas SMS (Short Message Service) may be used for communicating data messages including text messages with menu data, to the terminal, and for sending action commands from the terminal.
  • SMS Short Message Service
