Description

Wireless communication system with automatic response

The present invention relates to a wireless communication system, and more particularly, to a wireless communication system having an autoresponder function capable of performing an autoresponder function by storing a transmission message of a caller in a large memory attached to a handset. .

Conventionally, due to the limitation of the memory capacity of the memory installed in the handset, the large memory chip size, and the limitation of implementing the memory function in the handset, the size and weight of the handset, the limitation of the handset itself due to the functional processing, etc. It was difficult to add the auto-response function to the memory, and the software lacked the message compression technique.

As shown in Fig. 1, in the conventional wireless communication system, when an incoming call arrives, the voice mail system is switched to an environment where an incoming call cannot be answered or received.

When an incoming call occurs, the called party responds, but in an environment where the called party cannot receive a response, the call is switched to the voice mail system. An environment that cannot receive a response may include a caller's terminal malfunctioning or a call being heard, and if the terminal is turned off without a power-off message, it may not be answered even if the ring is ringing. This operation is made. Of course, the caller can use the voicemail system to leave a message to the called party. There are several ways to operate the voicemail system. An exemplary call processing path in which the conventional voicemail system operates is shown in FIG. When an incoming call occurs, the called party responds, but in an environment where the called party cannot receive a response, the call is switched to the voice mail system.

However, in the conventional wireless communication system described above, when an incoming call is received, the voice mail system is operated and stored in the voice mail system even though the called party cannot receive the call. In order to listen, there was an inconvenience that the called user had to restore the voice mail system. Accordingly, the user must check the message by restoring the voice mail system, so that the user must pay more fees and suffer the inconvenience of restoring the system.

The present invention has been made in view of the above-described problems of the prior art, and has a wireless response function capable of performing an automatic response function by storing the transmission message of the caller in a large memory added to the handset. Its purpose is to provide a communication system.

Wireless communication system with an automatic answering function of the present invention for achieving the above object, voice mail system for storing a voice message for a call when a call, exchange for connecting all the external calls, repeaters A fixed set consisting of a plurality of repeater control means for controlling, a plurality of channel control means for controlling the channel of the caller and the called party, respectively, and a large memory and a memory memory capable of compressing and storing the caller's voice message for the automatic response. In a wireless communication system composed of a plurality of handsets having a control unit for response control, when a caller's call request is made, the exchange sends a ringing tone to the called party's handset, and the caller's handset sounds as a ringing tone. ACK) to the exchange and repeat this to the handset of the called party. If there is no answer, it determines that the ring is locked and operates the answering machine so that the exchange sends the answering machine operation tone and the answering machine operation signal to the called party's handset and the caller's handset answering machine, respectively, and sends a message sent from the called party to the caller's side. Compressed and stored in the large-capacity memory, the message is completed and the message is sent to the exchange when the caller sends a message storage end message is characterized in that the exchange has an automatic response function to send a message storage confirmation signal to the callee's handset.

In the large memory of the handset, the voice message of the caller is converted into a digital signal using a vocoder, compressed and stored. When the large memory of the handset is saturated and the automatic response function is difficult to perform, the voice mail system can be operated.

Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

3 is a flowchart illustrating an automatic response operation process of a wireless communication system according to the present invention, and FIG. 4 is a view showing a call processing process when there is no response in a ring locked state in the wireless communication system according to the present invention. 5 is a block diagram of a wireless communication system having an automatic answering function according to the present invention.

The wireless communication system of the present invention immediately goes to the voice mail system when the conventional handset is not received even when the ring rings, but the present invention adds a function of automatically responding instead of the voice mail system.

When the auto-response function is executed, it controls to send the greeting simply and then records the caller's message in the memory. At this time, the memory function can be converted to a digital signal using a vocoder and compressed to perform an automatic response function more efficiently. Of course, if the memory is saturated and it is difficult to perform the auto-response function, it can be determined to operate as a voice mail system.

Wireless communication system with an automatic answering function of the present invention, as shown in Figure 5, the voice mail system (VMS) 510 that stores a voice message for the call when a call is received, by connecting all the external calls A switch (TC) 520 for giving, a plurality of repeater control means (RCU 1, ..., RCU N; 531, 532) for controlling the repeaters, and a plurality of channel control means (CCU 1) for controlling the channels of the caller and the called party, respectively. (CCU 2, ..., CCU N; 541, 542, 543), and a plurality of handsets having a control unit for controlling the memory and automatic memory response and a large memory capable of compressing and storing the caller's voice message for automatic response ( 551, 552, and as shown in FIG. 3, two incoming calls have an automatic response function added to the contents of the countermeasure, and require a message (audio, video, data) compression technique. In this case, an analog handset requires a vocoder chip for converting a voice signal into a digital signal.

Call processing of the wireless communication system with an automatic answering function of the present invention, as shown in Figure 4, when the caller's call request is sent from the exchange to the caller's handset, the caller's handset ringing The caller sends an acknowledgment signal (ACK) to the exchange. If there is no response from the called party's handset, the answering machine determines that the ring is locked and operates the answering machine so that the exchange responds to the called party's handset and the caller's handset answering machine. The exchanger sends the answering machine operation signal and the answering machine operation signal, respectively, to compress and store the message transmitted from the called party to the mass memory of the caller side, and after the completion of storing the message, the exchange sends the message storage end message to the exchange side. Automatic response by sending a message save confirmation signal to the caller's handset. Let's do it.

In the large memory of the handset, the voice message of the caller is converted into a digital signal using a vocoder, compressed and stored. When the large memory of the handset is saturated and the automatic response function is difficult to perform, the voice mail system can be operated. In addition, it is necessary to secure a memory capacity for storing the incoming call contents in the handset, and a function for controlling the incoming call should be added.

When the caller requests a call, the exchange sends a ringing tone to the called party's handset, sends a call acknowledgment (ACK) to the exchange with a ringing tone on the called party's handset, and the call is returned from the handset on the called party's side. If not, the answering machine determines that the ring is locked and operates the answering machine so that the exchange sends an answering machine operation tone and an answering machine operation signal to the called party's handset and the caller's handset answering machine, respectively, and sends a message to the called party. When the compressed message is stored in the large memory, the message is completed and the caller sends the message save end message to the exchange, the exchange sends a message store confirmation signal to the callee's handset to terminate all operations.

According to the present invention as described above, in addition to providing convenience to the user by applying an automatic answering function to a cellular or TRS handset, in the case of a pager, when a message is received, the caller is usually connected to the caller using a public telephone. If you are not around, or if you have a public phone, but there are a lot of people to use it, it may be difficult to check the message of the voice mail system, but it can be easily overcome by using the automatic response function.
