Description

System transmission receiver and method for transmitting and receiving character image including voice {System transmitter receiver and method for transmission receive character image comprise of voice}

The present invention relates to the transmission and reception of character images and voices, and more particularly to a character image transmission and reception system and a method for transmitting and receiving a character image and voice synthesized at the calling terminal and adapted to receive the same at the called terminal. It is about.

In general, character mail is transmitted by using text on bit images. Character service uses SIS (Simple Image Service) to transfer still or moving images to mobile terminal background and short message. It is a service to use.

Short Message Service Center (Short Message Service Center) is a communication service that is delivered in the form of a character (short text) of a limited size between the mobile terminal and the mobile terminal or between the mobile terminal and the Short Message Entity (SME). It is a system that has the function to store and forward the short message transmitted to the called subscriber terminal which cannot be received at the subscriber until the subscriber can receive it, and also deliver it to the incoming caller. .

Originally, the short message service was first proposed by the European Telecommunication Standard Institute (ETSI) by defining a point-to-point service that can transmit and receive up to 155 bytes of characters between incoming and outgoing terminals for application to European digital cellular communication systems. .

The characteristics of the short message service is that the short message can be delivered in the form of a database character using the access channel and the paging channel as well as the traffic channel, so that the service can be performed regardless of the operating state of the terminal.

SMSC can be used in both GMS (Group Special Mobile) and IS-41C networks. SMSC is an independent node with its own SPC (Signalling Point Code) in SS7 (Signalling System 7) network. It is connected to Home Location Register (HLR) and Mobile Service Center (MSC). It has a function of detecting the location of the receiver and delivering a short message to mobile subscribers via PLMN (Pubilc Land Mobile Network).

SMSC can send and receive numbers and letters in both directions between various text delivery systems (PC communication system, internet server system, mobile phone, etc.) and subscribers using mobile communication network. Of course, the mobile subscriber can also send a short message through a mobile terminal (generally a mobile phone), and the length of the short message that can be sent depends on the environment in which the SMSC is used. You can send short messages up to 160 characters (US) in the GSM environment and up to 200 characters (100 characters) in the IS-41C environment.

The SMSC implements the protocols and functions defined in GSM Technical Specification 03.40 and 09.02 and in TIA / EIA Technical Specification IS-41C (SP3588) and IS-136-A (TDMA).

The method of conveying a message by using text in such a character image does not have the effect that the character image is alive and the image itself speaks.

Accordingly, an object of the present invention has been made in view of the above-mentioned problems of the prior art, and synthesizes a voice to a character image and transmits the character, so that a character including a voice capable of transmitting a lively character image upon reception at a called terminal. It relates to an image transmission and reception system and a transmission and reception method.

Such a method of synthesizing and transmitting a character image and a voice includes accessing a wireless Internet, downloading a desired character image to a calling terminal, recording a voice to the calling terminal, and downloading the downloaded character image and the recorded voice. Synthesizing the character image, transmitting the synthesized character image and the recorded voice to a called terminal, separating the received character image and the voice from the called terminal, and separating the separated character image into the called terminal browser. And at the same time the voice is output through the speaker.

According to another feature of the present invention for achieving the above object, the calling party mobile terminal for downloading a character image and synthesized the voice image and the voice recording and transmitting the voice using a WAP protocol, and the character image Character server that provides a variety of character images to download the character image and the character image and voice data received from the calling mobile terminal is separated and the character image is displayed on the browser and the voice is output through the speaker is configured as a mobile terminal do.

Hereinafter, the configuration and operation according to the preferred embodiment of the present invention will be described with reference to the accompanying drawings.

1 is a view showing a character image transmission and reception system including a voice according to the present invention.

Character image transmission and reception system including a voice according to the present invention is the calling party mobile terminal 10 for downloading the character image, recording the voice, synthesizes the character image and the voice and transmits using the WAP protocol, and the calling party The caller's mobile terminal 11, which separates the character image received from the mobile terminal and the voice data and displays the character image on the browser and outputs the voice to the speaker, is connected to the mobile network. It is configured to be connected to the character server 12 and the swap gateway 11 to provide a variety of character images to download the character image.

First, a calling mobile terminal and a called mobile terminal are composed of a mobile terminal, a base station, a base station controller, and a mobile switching center in a mobile communication system according to a conventional mobile communication network. The mobile terminal is a digital cellular network (DNC). A mobile terminal (PCS), such as a personal communication service (PCS), and the base station changes the signal format between the mobile terminal and the base station controller to be suitable for the wireless link and the wired link. It is a means of access between each element function and cell operator, base station operation management, hardware and software service state management in base station, resource allocation and configuration for call traffic, information collection about base station operation, and mobile switching center Is the same as the base station controller management and mobile communication network. Configure an access point for user traffic with the mobile switching center of the mobile communication system.

Then, the calling mobile terminal receives the character image provided by the character server through the WAP through the browser of the calling mobile terminal. At this time, the WAP (Wireless Application Protocol Gateway) converts the WAP protocol and the Internet Transmission Control Protocol / Internet Protocol (IP / IP) in between. That is, all the mobile device's Internet service needs to go through the WAP gateway. The gateway requests the service again through the existing Internet wired network according to the swap protocol. Subsequently, the swap gateway receives the response from the Internet server and sends it back to the mobile terminal that originally requested the service using the swap protocol. Therefore, it automatically converts HTML (Hyper Text Markup Language) for desktop PCs, which are character servers, into WML (Wireless Markup Language) for mobile terminals such as pagers, portable personal digital assistants (PDAs), and mobile phones. .

The calling mobile terminal receives the character image provided by the character server, selects a desired character image, and downloads it to the character image storage device of the calling mobile terminal through a swap gateway.

Here, Download refers to an operation of transferring a program or a file from a storage device of a computer to another storage device having limited resources through a communication network.

Then, the voice is recorded in the calling mobile terminal, and the recorded voice and the character image selected and downloaded by the calling mobile terminal are synthesized into a data packet.

Herein, a data packet refers to a transmission unit of information transmitted with a predetermined maximum length, and a data packet includes a header including user data, an identification number, a source and destination address, and, in some cases, error control data. It consists of a binary number representing. The standard for packet exchange is specified in ITU-T Recommendation X.25.

Then, the synthesized character image and voice are transmitted to the called party's mobile terminal using a swap protocol.

At this time, the swap protocol structure is composed of a wireless application environment (WAE), a wireless session protocol (WSP), a wireless transaction protocol (WTP), a wireless transport layer security (WTLS), a wireless datagram protocol (WDP), and a wireless application environment (WAE). Defines a standard for the application environment for developing general and multi-purpose applications, and defines a WML (Wireless Markup Language), WMLScript, etc., to develop a small browser that can be applied to mobile devices, WSP (wireless session protocol) Defines HTTP / 1.1 equivalent function, defines session for long time use, provides suspend / resumer function for session management, and enables negotiation of protocol function. In addition, the WTP (Wireless Transaction Protocol) provides a transactional data transmission function, provides a reliable and unreliable transmission function, and also performs a retransmission function for error recovery. Wireless Datagram Protocol (WDP) provides security services based on TLS of the Internet, and provides security services such as authentication, non-repudiation, integrity, and security, and WDP (Wireless). Datagram Protocol provides port addressing for end-to-end transmission, and functions like the Internet's User Datagram Protocol (UDP).

Then, the character image and the voice received by the called party's mobile terminal are separated from the called party's mobile terminal. In this case, the separated character image is displayed through the called mobile terminal browser, and the voice data are decoded and demodulated together with the image to be output through the speaker.

As described above, the present invention synthesizes a character image and a voice, and transmits mails in different voices to various images, so that a character image utters as if a person moves and speaks.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention.

Therefore, the technical scope of the present invention should not be limited to the contents described in the examples, but should be defined by the claims.
