移动终端下载数据及移动终端间数据共享的方法和系统 Mobile terminal downloads the data between the mobile terminal and a method and system for data sharing

技术领域 FIELD

[0001] 本发明涉及信息通信技术领域,具体地说,涉及移动终端下载数据的方法,以及移动终端间数据共享的方法和系统。 [0001] The present invention relates to the field of information communication technology, specifically, the method relates to a mobile terminal to download the data, and a method and system for data sharing between mobile terminals.

背景技术 Background technique

[0002] 随着移动通信技术的发展,移动终端除了基本的通信功能外,还可用于娱乐,如看电影,下载大型软件。 [0002] With the development of mobile communication technology, mobile terminals in addition to basic communication functions, may also be used for entertainment, such as movies, software download large. 由于移动终端方便携带,如果能够利用移动终端进行娱乐,可增加人们的娱乐空间,如人们在野外旅游或在偏远地区(只要能够提供移动服务的地区)时,不仅可以利用移动终端通过因特网浏览各种新闻,查阅各种信息,还可利用移动终端观看电影。 Since the portable mobile terminal, if the mobile terminal can use for entertainment, it can increase people's entertainment space, as people travel in the wild or in remote areas (as long as they provide mobile services in the region), not only can take advantage of each mobile terminal browser via the Internet of news, access to a variety of information, but also watch movies using a mobile terminal.

[0003] 在现有技术中,移动终端可以通过GPRS(通用分组无线业务)或拨号上网,以媒体流的方式下载电影以便欣赏其内容,然而,在这种下载技术中,每部移动终端只能各自下载各自的内容,这时若有多部移动终端都希望观看同一部电影,就需要每一部移动终端下载该部电影,从而造成重复下载,并浪费带宽的现象。 [0003] In the prior art, the mobile terminal can be GPRS (General Packet Radio Service), or dial-up, so as to download a movie to stream the media to appreciate the contents, however, this downloading technique, every mobile terminal only can download their own content, then if multiple mobile terminal wants to watch the same movie, you need every mobile terminal to download the movie, resulting in duplicate downloads, and bandwidth-wasting phenomenon. 另外,在上述下载技术中,其下载速度通常小于播放速度,使得电影的观看效果不佳。 Further, in the above-described downloading technique, which is generally less than the download speed playback speed, so that the poor viewing a movie. 再者,每个人都重复下载,需要占用大量的带宽,同时也增加了占用带宽资源的时间,从而其资费也会增加。 Furthermore, everyone repeat the download, you need a lot of bandwidth, while also increasing the bandwidth resources of time, which will increase its tariffs.

[0004] 流媒体是一种新兴的网络传输技术,该技术简单来说就是应用流技术在网络上传输多媒体文件,而流技术就是把连续的影像和声音信息经过压缩处理后放上网站服务器, 让用户一边下载一边观看、收听,而不需要等整个压缩文件下载到自己机器后才可以观看的网络传输技术。 [0004] Streaming is a new network transmission technology, the technology is simply the application streaming technology to transmit multimedia files on the network, and streaming technology is the continuous video and audio information after the compression process put web server, allowing users to download side side view, listen to, without the need to wait for the entire compressed file downloaded to your machine after the network transmission technology that can be viewed.

[0005] 随着无线技术的发展,无线数据访问的带宽不断增加,移动终端处理能力不断增强,各种优质的流媒体业务已经比较成熟。 [0005] With the development of wireless technology, bandwidth wireless data access continues to increase, the mobile terminal processing capabilities continue to increase, a variety of high-quality streaming media business has been more mature. 通过流媒体的平台,移动终端可以进行低码率、 低速率的语音和视频流的新闻、电影或音乐等流式播放,以及可以进行直播业务的流式媒体播放;移动终端可以下载业务,下载媒体文件。 By streaming media platform, mobile terminals may be low bit rate voice and video news streams low rates, such as movies or music streaming, and streaming media players can live service; you can download mobile terminal business, download media files. 同时媒体文件可以通过DRM(数字版权保护)技术进行版权保护。 At the same time the media file can be copyright protected by DRM (Digital Rights Management) technology.

[0006] 在现有技术中,移动终端播放流媒体的主要方法为:移动终端首先与网络建立连接,然后,移动终端一边从网络测下载流媒体的数据流,一边实时地播放该数据流。 [0006] In the prior art, the main method of a mobile terminal to play streaming media are as follows: First, the mobile terminal establishes a connection to the network, then the mobile terminal while the data stream from the network to download the measured streaming media, while playing the data stream in real time. 该方法的主要特点为实时性、对网络带宽占有较大。 The main feature of this method is real-time, to account for a large network bandwidth.

[0007] 在实际应用中,经常会遇到两个用户需要同时收看同一个流媒体的情况。 [0007] In practical applications, often encounter two users need to watch the situation with a streaming media. 根据上面所述的方法,此时,该两个用户需要分别和网络建立连接。 The method described above, at this time, and the two network user needs to establish a connection. 如图1所示。 As shown in Figure 1. 然后,该两个用户分别建立一条空中信道,从该空中信道的空口进行流媒体的下载,之后,分别在本地进行播放。 Then, each of the two users to establish an air channel, downloading streaming media from the air channel air interface, and thereafter, were performed in the local playback.

[0008] 上面所述现有技术的移动终端播放流媒体的方法, The method of streaming media [0008] The above prior art mobile terminal displays,

[0009] 如果在同一时间进行流媒体下载、收看的用户过多,会造成网络侧设备负担过重。 [0009] If the streaming media download at the same time, users watch too much will cause the network side device overburdened.

[0010] 占用资源太多。 [0010] taking up too much resources. 如果上述两个用户实际距离相距并不远,在一个基站小区内,它们同时下载同样的内容,将造成一定的资源浪费。 If the actual distance of the two users not far apart, a base station in the cell, they are simultaneously download the same content, it will result in some waste of resources. 而且,在同一小区内不宜建立太多个数据连接。 Moreover, within the same cell should not create too many data connections. [0011] 在一定程度上限制了用户收看流媒体的积极性,因为用户既要购买版权文件,同时又要支付下载费用。 [0011] limit the enthusiasm of the user to watch streaming media to a certain extent, because the user is necessary to buy the copyright file, at the same time have to pay for the downloads.
