Abstract
The present invention relates to a mobile telephone with answering and recording functions. The mobile telephone comprises a speech encoding/demoding circuit, a multiplexer, a channel encoding/demoding circuit, a microprocessor and a memory, wherein the multiplexer is connected with the speech encoding / demoding circuit through a first data line; the channel encoding/demoding circuit is connected with the multiplexer through a second data line; the microprocessor outputs control signals and is connected with the multiplexer through a third data line; the memory is connected with the microprocessor through a fourth data line, wherein the microprocessor stores information from the first data line in a memory in response to a first user instruction; in response to a second user instruction, the microprocessor sends the information in the memory to a caller through the second data line and stores the caller's information in the memory.
Description
The relevant a kind of mobile phone of the present invention, the mobile phone that especially refers to have the answer phone function.
Mobile phone (being commonly called as mobile telephone) is universal day by day, but the mobile phone machine of tool answer phone function is not arranged at present on the market as yet.Sometimes, the user is inconvenient to receive calls in session or during rest, can turn off jingle bell, and open functional circuit of the present invention, the phone of coming in can be recorded, in order to avoid miss important information.
The object of the present invention is to provide a kind of mobile phone of tool answer phone function.
The object of the present invention is achieved like this.
The mobile phone of tool answer phone function provided by the invention comprises
One audio coding/decoding circuit;
One multiplexed apparatus, it links by one first data wire and audio coding/decoding circuit;
One channel coding/decoding circuit, it links by one second data wire and multiplexed apparatus;
One microprocessor, export a plurality of multiplexed apparatuses that control signal to, and by one the 3rd data wire and the binding of multiplexed apparatus, the microprocessor control signal bus is connected to above-mentioned audio coding/decoding circuit, multiplex machine, channel coding/decoding device, and storage arrangement;
One storage arrangement, it links by one the 4th data wire and microprocessor;
Wherein, first instruction according to a user, microprocessor can be stored in storage arrangement with an information of first data wire, second instruction according to the user, microprocessor can be given a speaker by second data wire with the information in the memory, and will come across speaker's information storage on second data wire in storage arrangement.
Now with embodiment in conjunction with the accompanying drawings, the present invention will be described.
Brief Description Of Drawings
Fig. 1 is a functional circuit block diagram of the present invention.
As shown in Figure 1, the present invention comprises radio circuit 11 (RF transmitter/receiv-er), channel coding/decoding circuit 13 (channel encoder/decoder), audio coding/decoding circuit 15 (voice encoder/decoder), multiplexer element 20 (multiplexer), pulse-code modulation/demodulator circuit 19 (PCM--pulse coded modula-tion/demodulation), digital-to-analog, A/D conversion circuit 21 (D/A, A/D), microprocessor 23, identification module 25 (subscriber identity module), memory 27, key device 29, display unit 28.Identification module 25 similar phone credits cards can insert in the different mobile phones and use, and expense is then collected to the account number of this card.
As the people who has the knack of wireless communication technique knows, and radio circuit 11 comprises the function that radio frequency receives and radio frequency transmits; Channel coding/decoding circuit 13 comprises chnnel coding and channel-decoding function, and the chnnel coding purpose is being given the ability of signal error corrigendum, and channel-decoding is then done the work of decoding; Audio coding/decoding circuit 15 comprises decoding and encoding function, speech coding is according to the RPE-LTP method (RegularPulse Excited-Long Term Prediction) as GSM (Global system Mobile) suggestion, the digital signal 150 of input is made speech coding, and tone decoding is then done opposite action; Pulse-code modulation/demodulator circuit 19 comprises pulse-code modulation (PCM) and pulse code demodulation, G.711, as consult the instruction committee (CCITT) with the international telegram phone is standard, then the data transfer rate of its output 150 is 64KbS, and as G.721 being standard with CCITT, then data transfer rate of its output 150 is 32KbS; Conversion between 21 responsible signal samplings of D/A conversion circuit (sampler) and digital signal, the analog signal; In addition, element 31 is microphone (Mic), and element 32 is earphone (Earphone); Microprocessor 23 is according to various states in the system, and output control signal 231,232,233,234,235,236,237,238,239 is to each relevant elements, with the running of control mobile telephone system.
Tool one multiplexer element 20 of the present invention, it can be a data-signal switch or is a demultiplexer (demultiplexer), link with first data signal line 202 and audio coding/decoding circuit 15, link with second data signal line 200 and channel coding/decoding circuit 13, link with the 3rd data signal line 201 and microprocessor 23.Multiplexer element 20 is also imported a plurality of control signals 234.
When the user desires to record the information of " request message ", can import first order of recording message earlier, this requirement is after holding wire 291 is informed microprocessor 23, microprocessor 23 can send control signal 234 and remove to control multiplexer element 20, the digital signal of the request message that appears on first holding wire 202 is sent on the 3rd holding wire 201, and be not sent on the secondary signal line 200, after microprocessor 23 is received signal, it is stored in the interior a certain sector address of memory 27 by the 4th holding wire 230.
When the user set mobile phone in the answer phone pattern, microprocessor sent control signal 234, and set predetermined loud number.When phone is come in, and when surpassing predetermined louds number, microprocessor 23 is connected circuit automatically, and takes out " requiring to leave a message " information from memory 27, sends the speaker to by holding wire 230,201,200,130,110.
After the information that finishes " requiring message ", if the other side leaves word, the information of then leaving word then is stored in another sector address of memory 27 by holding wire 110,130,200,201,230.And after message interrupts, microprocessor 27 cuts off the circuit of mobile phone.
And when the user imported second order of playing message, 27 in microprocessor took out calling side's message information to memory 27, played back by holding wire 230,201,202,150,190 and via earphone 32.
If prevent delay (delay) effect that causes by microprocessor, can adopt microprocessor with direct memory access (DMA) control (DMA) function.Memory 27 is if also can go into the message unloading memory in the identification module 25 (subscriber identity module) when not enough.
