The processing unit 503, as stated above, includes the device controller 511, the connection manager 513, the exchange network manager 515, and the call manager 517. These components are described below.
The connection manager 513 serves to manage connections with one or more mobile terminals 201 and 207 and the external device 209. For connections with mobile terminals 201 and 207 and the external device 209, an exchange of information such as the initial unique identifier is needed. Once their information is registered in the connection manager 513, mobile terminals and other devices may be automatically connected without the need for re-registration if they move to a pertinent area from outside the area.
The exchange network manager 515 configures an extension telephone network between two or more connected mobile terminals 201 and 207 in addition to managing connections and services between the mobile terminals 201 and 207. To this end, one or more mobile terminals could be connected to the connection manager 513. Otherwise, the exchange network manager 515 repeats searches for mobile terminals, other devices, or for a wireless network until the desired conditions are satisfied. Also, if a connection is made to an external telephone network, such as an IP network supporting a VoIP phone, the exchange network manager 515 may configure the extension telephone network including the external telephone network, and manage connections and services between mobile terminals 201 and 207 and the VoIP phone. In addition, if a new incoming call request is received at the second mobile terminal 207 connected to the connection manager 513 while a call is being processed by controlling the first mobile terminal 201 connected to the terminal stand 203, the exchange network manager 515 may perform call waiting or call forwarding depending on the user's preference.
The call manager 517 serves to manage and process incoming/outgoing calls received from mobile terminals 201 and 207. The call manager 517 manages and processes the incoming/outgoing call received from the first mobile terminal 201 connected to the terminal stand 203, and may also manage and process the incoming/outgoing call from the second mobile terminal 207 connected to the connection manager 513. If a new incoming call request is received at the second mobile terminal 207 connected to the connection manager 513 while a call is being processed by controlling the first mobile terminal 201 connected to the terminal stand 203, the call manager 517 may inform the exchange network manager 515 of the receipt of the incoming call request.
The device controller 511 controls functions of mobile terminals 201 and 207 and the external device 209 connected to the connection manager 513 and replies to incoming/outgoing calls received from the call manager 517, and if two or more incoming calls are received at the same time, the device controller 511 controls them.
The sensor unit 505 serves to recognize, handle and process information from various sensors including a position sensor, an acceleration sensor, and a pressure sensor. The sensor unit 505 is controlled by the device controller 511 in the processing unit 503, and its sensors may be used in additional applications supplied in or downloaded by mobile terminals 201 and 207, like games.
The input/output interface 507 includes a keyboard, a mouse, a touch screen, a digital TV, a computer monitor, etc. During data input, the input/output interface 507 is used to input desired user information to connected mobile terminals 201 and 207. During data output, the input/output interface 507 is used to exhibit the original content of mobile terminals 201 and 207 or to exhibit the content after changing a user interface or a resolution so as to be suitable for the output screen. The call interface 509 includes a speaker and a microphone, and is used for voice calls with another party when it is connected to other mobile terminals or an external device 209.
A process of controlling mobile terminals and external devices using the above components will be described in conjunction with
In step 605, the multifunction remote control device 211 can control basic functions of the first mobile terminal 201. The basic functions of the first mobile terminal 201 include the call sending/receiving function 301 and the control function 303. The user may make a phone call using the multifunction remote control device 211 instead of the first mobile terminal 201, and control and enjoy content of the first mobile terminal 201 on the secondary display 205.
In step 607, the user can perform additional functions of the first mobile terminal 201 by means of the multifunction remote control device 211. Performance of the additional functions is determined depending on the connection status between devices, the requested service, and the operation conditions. For example, if two or more mobile terminals are connected to the multifunction remote control device 211, or the external device 209 is connected to the multifunction remote control device 211, the additional functions may be performed. The additional functions include a control function 305 for the external device 209 such as a VoIP phone, a call exchange, or a PBX function 307 for enabling calls between mobile terminals connected to the multifunction remote control device 211, and a sensor & game control function 309 for providing convenience to the user by controlling the sensors, and any other additional functions for user convenience.
If the user determines to perform the additional functions in step 607, the multifunction remote control device 211 selects one of the multiple additional functions in step 611, and manages and controls the selected additional function in step 613. In step 615, the multifunction remote control device 211 determines whether there is a change in the service environment, for example, whether the first mobile terminal 201 is disconnected from the terminal stand 203 or powered off. In the case of a change in the service environment, the multifunction remote control device 211 ends its operation, returning to the previous service environment in which the first mobile terminal 201 was disconnected from the terminal stand 203. However, in the absence of a change in the service environment, the multifunction remote control device 211 returns to step 613 and continues to manage and control the selected additional function.
If the user determines not to perform the additional functions in step 607, the multifunction remote control device 211 determines in step 609 whether there is a change in the service environment. In the case of a change in the service environment, the multifunction remote control device 211 ends its operation, returning to the previous service environment in which the first mobile terminal 201 was disconnected from the terminal stand 203. However, in the absence of a change in the service environment, the multifunction remote control device 211 returns to step 605 and continues to control the basic functions of the first mobile terminal 201.
As is apparent from the foregoing description, the present invention can simultaneously remotely control the key functions and the additional functions of mobile terminals, and can provide outputs to a digital TV or a PC monitor, enabling convenient use of the functions that the user couldn't enjoy on the small screen of the mobile terminal.
While the invention has been shown and described with reference to certain exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
