TH331A3 - Mobile phone battery charger with forwarding device for forwarding incoming calls from the mobile phone to the fixed phone. - Google Patents

Abstract

Mobile phone battery charger (3) with a switcher (1) that allows users to answer calls. The incoming call of a cell phone (4) made by a stationary phone (21) has been revealed. A switching device (1) is incorporated by two leased lines (L1, L2) that are connected to the network. Public Telecom Two fixed telephone cables (P1, P2) to connect stationary telephones (21). Two telephone cables (R1, R2) that are physically connected. The power is supplied to the headphone output connector (3f ?, 3e?) Of the mobile phone (4) through a contact device (3f, 3e) respectively, and two microphone connection cables (T1, T2) received. Connect to the connector The microphone output (3c ', 3d') of the mobile phone (4) through the contact device (3c, 3d) respectively, the user can receive the incoming call of the mobile phone (4) by the fixed telephone. At (21) under the control of the switching device (1)

Claims (3)

1. Cell phone battery charger (3), which is provided with a recessed area (31) that has been arranged to contain more than one contact device (3a, 3b, 3c, 3d , 3e, 3f) corresponding to the output connectors (3a \ ', 3b \', 3c \ ', 3d \', 3e \ ', 3f \') that are arranged on the mobile phone (4). Was put in Going into the recessed area (31), which has been characterized as The battery charger (3) is provided with an interchange device (1) consisting of two leased lines (L1, L2) that are connected to the public telecommunication network, a telephone connection line. that Two fixed installations (P1, P2) for connecting stationary telephones (21). Listen to the number of two wires (R1, R2) that are electrically connected to the headphone output connector (3f \ ', 3e \') of the mobile phone (4) via a contact device (3f, 3e). Respectively, and two microphone cables (T1, T2) that are connected to the microphone output connector (3c \ ', 3d \') of the mobile phone (4) via a contact device (3c, 3d) respectively so that the user can answer the incoming calls. The acquisition of the cell phone (4) is achieved by the fixed telephone (21) under the control of the switching device (1). 2. Mobile phone battery charger according to claim 1, where the battery charger The battery consists of a circuit for charging a battery (5) for charging the mobile phone battery, which is attached to the Cell phone 3. Mobile phone battery charger as claimed in claim 1, where the switching device It consists of - Central Processing Unit (15) - Communication loop switching circuit (11) that is connected to the leased line (L1, L2) and the fixed telephone link (P1). , P2) - relay (16) provided with two supplied contact switching devices (RY1, RY2). Arranged in a communication loop switching circuit (11), can be controlled by the central processing unit (15) - Incoming call detection circuit (18) with the input line (S2) received. Connect to the cable Connect the headphones (R1) to detect the incoming call of the mobile phone (4) and the output call (S3) that has been connected to the processor (15) capable of transmission. Output signal To the processor (15) via an output line (S3) when it detects an incoming call - buzzer generation circuit (17) for generating a simulated ring signal that can be controlled by Central Processing Unit (15) - DTMF decoding circuit (13) that is connected to the communication loop switch circuit (11) to receive and decode the DTMF signal transmitted by the phone installed. Stationary (21) and transmits the decoded DTMF signal to the central processing unit (15) - the audio codec (14) is used to convert the mobile phone audio signal (4) that is transmitted. From the headphone interface cable (R1, R2) and the microphone interface cable (T1, T2) to a pattern. The appropriate audio signal is connected to the stationary telephone (21) through the output wires (R, T) and the -Power circuit (12) that is connected during the loop switching circuit. Communication (11) and output lines (R, T) of the audio converter circuit (14) to supply power to the switching device (1).
