条件确定单元73，用于在所述接收方终端登录鉴权通过后，判断所述接收方终端是否有临时文件需要接收；若有，则确定所述接收方终端满足再次接收文件条件。
本发明实施例还提供了一种点对点文件传输的系统，如图8所示为本发明实施例所提供点对点文件传输的系统结构示意图，所述系统包括：上述实施例所述的终端和服务器中的各个单元。
值得注意的是，上述终端、服务器和系统实施例中，所包括的各个单元只是按照功能逻辑进行划分的，但并不局限于上述的划分，只要能够实现相应的功能即可；另外，各功能单元的具体名称也只是为了便于相互区分，并不用于限制本发明的保护范围。
本发明的终端（包括发送方终端和接收方终端）可以为手机、计算机、固话终端；服务器可以为任何网络硬件设备，如计算机，基站等。
另外，本领域普通技术人员可以理解实现上述方法实施例中的全部或部分步骤是可以通过程序来指令相关的硬件完成，相应的程序可以存储于一种计算机可读存储介质中，上述提到的存储介质可以是只读存储器，磁盘或光盘等。
综上所述，本发明实施例能够提高点对点文件传输的效率，提升用户体验，并减少了网络带宽资源浪费。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明实施例揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应该以权利要求的保护范围为准。
