BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally relates to wireless communication networks, and more particularly to wireless network systems and methods for efficiently transmitting multimedia information. [Prior Art] Mobile terminals (e.g., mobile phones, PDAs, etc.) have become common devices for contacting others. Various forms of information such as sound, text, image, image 'audio, video, etc. can be transmitted and received by the mobile terminal. Mobile terminals are becoming more popular and popular, and many functions have been added and enhanced on mobile terminals. One of the functions is to allow interworking of multimedia information between mobile terminals. Multimedia information relies on high speed transmission. With the introduction of advanced wireless communication technologies, such as GPRS (General Packet Radio Service) and 3G (Third Generation Mobile System) technology, it has become a reality to send and receive media information. Several industry standards have been proposed in the transmission and acceptance of multimedia messages. One of the standards is Multimedia Information Service (MMS), which is defined in accordance with the technical specifications of 3GPP (Third Generati〇n Partnership Project '3rd Generation Partnership Project). The technical specification of multimedia information refers to 3GPP TS22.140, 3GPP TS23. .140 and 3GPP TS 26.140. Such standards allow users to send and receive formatted texts and images by a multimedia information consumer agent using a mobile terminal supporting multimedia information standards and an internet site having a web server supporting multimedia information standards. , multimedia information in photo images, audio and video clips. The multimedia information user agent refers to a user equipment (UE), a mobile station (MS) or a mobile terminal or a peripheral device that performs a multimedia information specific operation in terms of using 0\89\89389 DOC • 6 - 1336578. An application. In this case, the media proxy user agent can be an application that exists on a mobile phone or even a web server. Multimedia information standards support standard image formats (eg GIF (Graphics)

Interchange Format, Graphic Interchange Format) and JPeg ( j〇int

Photographic Expert Group 'Joint Photographic Experts Group)), video formats (such as MPEG (Motion Pictures Experts Group) 4) 'and audio formats (such as μρκμρεο) Audi〇Layer_3, audio compression format) and MIDI (Musical Instrument Digital Interface, instrument digital interface)). Thereby, the video sequence, the audio clip and the high-quality image can be downloaded from the WAP (Wireless Application Protoco) site to the mobile terminal, and transmitted to the mobile terminal by attached accessory components such as a digital camera, or Received as a multimedia message, photos, audio and video clips can be stored in the mobile terminal for later use. The media can also be sent to another mobile terminal that can accept multimedia information or sent to an email address. site. Figure 1 shows a multimedia media reference structure defined in accordance with the Third Generation Partnership Project (3Gpp). This is a developing 3G system specification structure.

〇AS9\89389 DOC 1336578 Servers 42 to 48. The multimedia messaging/server 20 is also coupled to an external multimedia messaging/server 40 located in another Multimedia Messaging Service Environment (MMSE). This environment is different from the Multimedia Information Service Environment (MMSE) in which the multimedia information relay/server 20 exists. Multimedia Information Service Environment (MMSE) refers to a collection of multimedia information specific network components under a single administrative control and may include more than one multimedia information relay/server. The multimedia information relay/4 division is connected to the 0 0, and the multimedia information user agent a in a multimedia information service environment (MMSE) and the multimedia information user agent b in the other MMSE Communication. Figure 2 is a simplified diagram showing how multimedia information can be transferred between two multimedia information user agents in the same Multimedia Information Service (MMSE) in a conventional manner. A multimedia information user agent provides the following application layer. Initiating a request to transmit a MM to another multimedia message, user agent, multimedia information (MM) retrieval, terminal capability negotiation, multimedia message (MM) selective combination , the submission of multimedia information, the display of multimedia information MM, and the like. On the other hand, a multimedia message relay/server is responsible for providing storage, generating notifications and reports, and general information processing. A multimedia message relay/server also provides other functions, such as generating charging data records (cDR) for billing purposes. As shown in Fig. 2, the multimedia information user agent A can transmit a multimedia message to another multimedia information user agent c by means of the multimedia information/server 2, and vice versa. For example, a multimedia

〇 \89\89389 DOC 1336578 Information User Agent A submits a multimedia message MM to the multimedia information relay/feeder via WAP or TCP/IP. The multimedia message relay/feeder 20 will forward the multimedia information mm to the user agent c. Figure 3 is a simplified schematic diagram showing how multimedia information can be transferred between two multimedia information consumer agents in different Multimedia Information Service Environments (MMSEs) in a conventional manner. As shown in FIG. 3, a multimedia message user agent A can send a multimedia information MM to a multimedia information user agent via the multimedia information relay/server 20 via WAP or Tcp/Ip. 2. The multimedia information MM will be forwarded by the multimedia information relay/server 40 to the user agent & different users in the same or different multimedia information service environment (MMSE) as described elsewhere There are some conventional methods for communicating multimedia information between agents. The most important lack is the waste of baby's network resources, especially for multimedia messaging/servers, which is due to the need for multimedia messaging/server processing and forwarding of many multimedia messages between user agents. Huge multimedia information exchange. All multimedia information sent or driven by a multimedia information consumer agent must pass through at least one multimedia information relay/server. For example, the multimedia information relay/feeder must receive the multimedia information sent from the multimedia information user agent and transfer the information to the other multimedia information user agent, even if it is a user of two multimedia information. This must also be the case when the agent is located in the same Multimedia Information Service Environment (MMSE). Therefore, at least two processes need to be performed, that is, a multimedia information is transmitted by a multimedia information user agent.

〇\S9W9389D〇C 1336578 to the multimedia information relay/server, and then the same multimedia information MM is forwarded to another multimedia information user agent by the multimedia information relay/server. If the two multimedia information user agents are located in two different multimedia information service environments (MMSE), __ additional processing is required to transfer the multimedia information MM from the multimedia information relay/feeder to another multimedia. Information relay/server. This will inevitably produce considerable delays in delivering multimedia information. Furthermore, since the multimedia information MM usually has a large capacity, it is necessary to store a high-performance server with a very large capacity. In this way, providers of multimedia information services have to add very high costs to configure and maintain the network. Therefore, it is very necessary to provide a wireless network system to enable multimedia information to be effectively transmitted, thereby not only saving valuable network resources, but also speeding up the transmission speed of multimedia information MM between two multimedia information user agents. . _. SUMMARY OF THE INVENTION The present invention provides a wireless network system capable of directly transmitting multimedia information from an originating multimedia information user agent to a destination multimedia information user agent. According to an embodiment of the invention, the wireless network system includes a multimedia information feeding device that receives a request from the originating multimedia information user agent to send the multimedia information to the destination multimedia information user agent.
