MOBILE PHONE SWITCHBOARD

Abstract: The mobile phone switchboard is a central unit, which operates as a mobile phone which is attached to other internal units (1, 2, 3, ..., 9) or more. It is similar to the usual mobile phone handsets and it is equipped with 4 illuminating lights (Inq., Tran., I, II). With the mobile phone switchboard it becomes possible for a third party to operate mobile phones (such as disabled people or even more children and so on), with controlled operation costs. At anytime parents are able to communicate with their children and vice versa, with controlled cost via the central unit. Additionally, the mobile phone switchboard has the following specifications: 1. modification of the central unit to operate in Direct Inward Dialing (D.I.D) for higher benefit of the mobile phone network; 2. call transfer to other telephone units/numbers; 3. simultaneous conversation with several calls.

Description: DESCRIPTION TITLE: MOBILE PHONE SWITCHBOARD Technical field where invention aims This invention refers to a mobile phone unit which consists of keyboards for dialing, registering, selection of the operation menus of the unit, screen, aerial, and rechargeable battery. Level of previous technology and assessment of it Equipment of such type is already known. These devices are loaded with a secret PIN code, for example 5555, and a calling code for example 094 - 802350. Use of this device is restricted to only one person at a time, therefore resulting to a high fixed operation cost and on the other hand control on the cost of use can only be performed by the person which operates it. The above results to the fact that this device cannot be used by third party, such as disabled people or children and so on, with controlled operation costs. Introduction of the invention The mobile phone switchboard consists of a central unit (handset) which operates as a mobile switching centre connected to several phone handsets 1 , 2, 3,...9 or more. It is similar to the existing mobile phone devices and is equipped with 4 extra illuminated buttons (Inq., Tran., I. II). The ing . for the Inquiry button is used to block every Incoming call to: a. Change the communication of the calls. b. Pick a new number of a connected phone unit or another mobile or conventional (wired) telephone number. The Tran button, for transfer, can transfer incoming calls to an internal or external phone unit that we have selected. The button i illuminates with the first incoming or outgoing call. The button _ illuminates with the second incoming or outgoing call. The mobile phone switchboards are capable of: 1. Handling a conversation with more than one internal or external telephone lines. 2. Receive and transfer, if it is required, calls from internal phone units 1 , 2, 3,...9 or other mobile or conventional telephone numbers. 3. To select the phone units that can directly accept incoming calls. (Not through the switchboard). 4. To select which internal units can remain available to communicate with other internal or external phone units, (not through the switchboard). 5. To cut off all communications of all connected units by operating the Off button on the central unit. 6. To display on the central unit: a. The number of the unit that is engaged. b. The total cost of the call. Advantages of the invention With the introduction of the mobile switchboard, the use of mobile phones is extended to third party, such as disabled people and specially children, with controlled operation cost. Parents can communicate at anytime with their children and vice versa with controlled cost through the central unit. I There is an opportunity for the mobile phone makers to increase their business by introducing new products in their range, (Portable switching handsets- switchboards- of mobile phones), while the existing mobile phones will be used as internal units or stand alone units. There is an increased efficiency in the use of the existing telephone network under a lower operating cost by introducing a multiple connection point of mobile phone units.(Multiple use of mobile phones via one or more numbers). Increased number of users and the market for mobile phones. Reduced operation costs for consumers (i.e. the fixed cost for the central unit plus a small fee for any extra unit attached to it). How it works MOBILE PHONE SWITCHBOARD PIN DIALING NUMBER Central unit 5550 094-802380 Internal unit No. 1 5551 094-802381 Internal unit No. 2 5552 094-802382 Internal unit No. 9 5559 094-802389 1. INCOMING CALL a) Regardless the number which is called 094-802380...094-802389, all incoming calls pass through the central unit i.e. switchboard (dialing number 094-802380). In the case in which the central unit operator wishes to transfer the incoming call to another internal unit, either mobile phone or conventionally wired phone, presses the button Inq., selects the number of the unit or the phone number to which wishes to transfer the call (for example internal unit No 3, 094-802383) and transfers the call by pressing the button Tran. b) Through menu (for example No 2), the central unit can operate as Direct Inward Dialing (D.I.D), i.e. the central unit can let free access to the telephone network to as many internal units as it wishes from No. 1 to...No. 9 in order to receive direct calls not through the central unit. Example: 1 )Press the button Menu and the button 21 to let access to internal unit No. 1. 2) Press the button Menu and the button 22 to let access to internal unit No. 2. 3) Press the button Menu and the button 29 to let access to internal unit No. 9. 4) Press the button Menu and the button 20 to let access to all internal units. In this way somebody can directly select the unit on which wishes to be connected. (For example unit No. 3 calls 094-802383.) 2. OUTGOING CALL a) All the internal units communicate through the central switching unit (dialing number 094- 802380). The central unit can transfer the call to another internal unit or telephone number by pressing of the buttons Ing. & Tran. Like in the example __a b) Through menu (For example No 3), the central unit can let as many internal units as it wishes starting from No 1.. No. 9, to be able to make direct calls that are not controlled by the central unit. Example: 1)Press the button Menu and the button 31 in order to let the internal unit No.1 to make outgoing calls. 2) Press the button Menu and the button 32 to let the internal unit No. 2 to make outgoing calls. 3) Press the button Menu and the button 39 to let the internal unit No. 9. 4) Press the button Menu and the button 30 in order to let ail the internal units attached to the central unit to be able to make outgoing calls. By the use of menu No. 2 and menu No. 3 the central unit can block or let through incoming or outgoing calls or both to pre - selected internally attached units. (For example by pressing menu 23 and menu 33 the internal unit becomes autonomous to incoming or outgoing calls. 3. CONVERSATION WITH MORE THAN ONE CALLS With the first incoming call, button I illuminates. If there is a second call then button H . illuminates too. When the user does not want to speak with incoming call No. 1 and wishes to speak with incoming call No. 2, presses button __ to block incoming call No. 1 and then by pressing the button 11 speaks with the 2nd call. In case he wishes to come back to call No. 1 , presses the button ___, blocks the 2nd call and by pressing the button [ speaks to the 1st call. If he wishes to keep the 1st line and speak with a new line, presses the button ing.., blocks the 1st line and then selects the new number of the line with which wishes to speak.

Claims: CLAIMS Previous situation The mobile phone switchboard is an extension in the use of mobile phone handsets which consists of keyboards for dialing and registering, selection of the operation menus of the unit, display, aerial and rechargeable battery. Equipment of such type is already known. These devices are loaded with a secret PIN code, for example 5555, and a calling code for example 094 - 802350. Use of this device is restricted to only one person at a time, therefore resulting to a high fixed operation cost and on the other hand control on the cost of use can only be performed by the person which operates it. The above results to the fact that this device cannot be used by third party, such as disabled people or children and so on, with controlled operation costs. 1st Claim The mobile phone switchboard consists of a central unit (handset) which operates as a mobile switching centre with controlled operation costs and it is connected to several phone handsets 1 , 2, 3,...9 or more. The internally connected (slave) handsets can be used by third party, such as disabled people or children and so on, with total control on the operation costs. It is similar to the existing mobile phone handsets and is equipped with 4 extra illuminating buttons (Inq.Tran., I, II). The ing for the Inquiry button is used to block every incoming call to: a. Change the communication of the calls. b. Pick a new number of a connected phone unit or another mobile or conventional (wired) telephone number. The Tran button, for transfer, can transfer incoming calls to an internal or external phone unit that we have selected. The button i illuminates with the first incoming or outgoing call. The button M illuminates with the second incoming or outgoing call. In addition through the menu the central unit handset can let through incoming or outgoing calls or both for any internally connected (slave) handset unit. In this way the chosen slave units can communicate directly with the network and not through the central unit. (Direct Inward Dialing D.I.D). The mobile phone switchboards are capable of: 1. Handling a conversation with more than one internal or external telephone lines. 2. Receive and transfer, if it is required, calls from internal phone units 1 , 2, 3,...9 or other mobile or conventional telephone numbers. 3. To select the phone units that can directly accept incoming calls. (Not through the switchboard). 4. To select which internal (slave) units can remain available to communicate with other internal or external phone units, (not through the switchboard). 5. To cut off all communications of all connected units by operating the Off button on the central unit. 6. To display on the central unit: a. The number of the unit that is engaged. b. The total cost of the call. Therefore the introduction of the use of the central switchboard handset unit in mobile telephony, aims to offer operation of several mobile phone handsets under the absolute control of operation costs. In addition the use of Direct Inward Dialing (D.I.D.) in mobile phones aims to a more efficient use of the existing telephone networks, thus taking the most, in terms of actual operating time with reduced costs. (Ability of multiple use of one or several mobile phone numbers). 2nd Claim As it was described in the 1st Claim the mobile phone switchboard handset is characterised by the fact that it can transfer calls to either mobile phones or conventional with the attachment of two new buttons In ;. and Tran. or via the Menu display of the central mobile switchboard handset unit. When the central handset unit wishes to transfer the call to another internally connected (slave) handset unit, mobile or wired phone, presses the Ing ^ button, selects the number of the unit or the telephone number (mobile or conventional) and transfers the call by pressing the button Tran. 3rd Claim As it was described in the 1st Claim, the mobile phone switchboard handset is capable to perform conversation with more than one calls in mobile telephony, with the attachment of two new buttons i and M or via the Menu display of the central mobile switchboard handset unit. When the central handset unit wishes to block the first call and allow conversation with the second, presses the button ing,. to block the first incoming call and by pressing the button M. speaks with the second call. In case he wishes to come back to the first call, presses the button ing ^ blocks the second call and by pressing the button i speaks to the first call. If he wishes to keep the first line and speak with a new line, presses the button Ing., blocks the 1st line and then selects the new number of the line with which wishes to speak. The same operation can be performed via choices available in the menu of the central mobile switchboard handset unit.
