摘要： A method is proposed for a mobile terminal in mobile communication systems to transfer non-speech data in voice channel, comprising steps of: encapsulating the non-speech data to be sent to another mobile terminal into IBD frames; storing said IBD frames in a buffer; detecting whether a speech burst sent to said another mobile terminal is over; checking whether there is non-speech data to be sent to said another mobile terminal if detecting that said speech burst is over; sending at least one non-speech data to said another mobile terminal via voice channel if there is non-speech data to be sent. By modifying the SID frame and silence speech frame, this method realizes transmission of non-speech via voice channel rather than via dedicated data channel, so as to save radio resources of the system.

摘要： The present invention provides a wireless network system that enables direct wireless delivery of a multimedia message from a first MMS user agent to a second MMS user agent. In accordance with one embodiment of the invention, the wireless network system includes a MMS server that receives, from the first MMS user agent, a request to send a multimedia message to the second MMS user agent. The request includes an identification (ID) number of the second MMS user agent. From a core network, for example, the MMS server obtains an Internet address of the second MMS user agent based on the ID number of the second MMS user agent, if the ID number is not an Internet address of the second MMS user agent. Then the MMS server forwards the Internet address to the first MMS user agent to enable the first MMS user agent to wirelessly deliver the multimedia message directly to the second MMS user agent using the Internet address. Therefore, by not involving a MMS server in delivering multimedia messages, a substantial amount of network resources is saved, and delivery speed of multimedia messages is significantly increased. As a result, the performance of the overall network system is greatly improved.

摘要翻译： 本发明提供一种无线网络系统，其能够将多媒体消息从第一MMS用户代理直接无线传送到第二MMS用户代理。 根据本发明的一个实施例，无线网络系统包括MMS服务器，其从第一MMS用户代理接收向第二MMS用户代理发送多媒体消息的请求。 请求包括第二MMS用户代理的标识（ID）号码。 例如，从核心网络，如果ID号不是第二MMS用户代理的因特网地址，则MMS服务器基于第二MMS用户代理的ID号获取第二MMS用户代理的因特网地址。 然后，MMS服务器将互联网地址转发到第一MMS用户代理，以使得第一MMS用户代理能够使用因特网地址将多媒体消息无线地直接传送到第二MMS用户代理。 因此，通过不涉及MMS服务器传送多媒体消息，节省了大量的网络资源，显着提高了多媒体消息的传送速度。 因此，整个网络系统的性能大大提高。

摘要： The invention allows a portion of a multimedia message, usually the beginning part of the message to be delivered to and stored on a mobile terminal beforehand. When a user wants to view the message, the portion of the message stored locally will be played back immediately, while at the same time a user agent residing in the mobile terminal will contact a media server for the remaining contents using the streaming technology. This would give the user an impression that the whole message is stored locally since there is nearly no noticeable delay in the playback, thus providing a much better user experience. The partial contents down-loaded can be a portion of the whole multimedia message, or an muntrelated rich-media message provided by a third party as an advertisement. In this way, the usage of the local storage space on the mobile terminal will be much more efficient.
