本发明实施例提供了一种协作传输的方法,用于视频、音频等流行数据文件的传输过程中,其流程图如图2所示,包括:
101、获取用户终端当前使用的目标分块文件以及与所述目标分块文件使用顺序相邻连续的已缓存完的,用户终端未使用的若干分块文件。
其中,确定某个分块文件为目标分块文件包括两种可能的:第一种是,当用户终端应用某个文件时,该用户终端正使用到该文件的某一点时,而该点在该文件的某个分块文件上,则该分块文件即为目标分块文件;第二种是,当该用户终端正在使用的该文件的某一点,正好在该文件的相邻两个文件分块的交界处,为了能够准确计算该文件目前可以连续使用的剩余时间,选择两个分块文件中使用顺序靠后的分块文件作为目标分块文件。
为了更加形象具体的描述目标分块文件,假设用户正在下载观看某个视频文件,具体举例说明。
第一种可能:假设该视频文件播放到12分40秒这一时间点,该视频文件按照时间原则分块,每5分钟为一分块文件。因此,12分40秒这一时间点在该视频文件播放时间为10至15分这个时间段对应的分块文件中,所以播放时间在10至15分这个时间段对应的分块文件即为目标文件;
第二种可能:假设该视频文件播放到10分00秒这一时间点,这一时间点正海为播放时间在5到10分这个时间段对应的分块文件与播放时间在10到15分这个时间段对应的分块文件的交界点,选 择播放时间在10到15分这个时间段对应的分块文件为目标分块文件。
102、根据所述的目标分块文件以及与所述目标分块文件使用顺序相邻的若干连续的已缓存完,用户终端未使用的若干分块文件,计算用户终端当前可连续使用的已缓存完的分块文件的第一使用时间。
其中,第一使用时间是文件当前使用进程到该进程之后并且与该进程相邻的用户可用的进程时间。因此,第一使用时间包括目标分块文件剩余的未使用的部分的可用的时间以及使用顺序在目标分块文件之后的并且与目标分块文件相邻的若干连续的已缓存完分块文件可用的时间的总和。
103、获取传输第一指定基站中在所述目标分块文件使用顺序相邻连续的已缓存完的若干分块文件之后的相邻下一个未传输的第二指定分块文件需要的第一传输时间以及传输当前传输速率最快的第二基站中的与所述目标分块文件对应的未传输的第三指定分块文件需要的第二传输时间。
104、比较所述第一传输时间以及第二传输时间的总和与所述第一使用时间。
需要说明的是,当传输速率最快的基站传输与该目标分块文件对应的未传输的第三指定分块文件与按使用顺序需要传输的下一个未传输的第二指定分块文件是同一分块文件时,则直接传输该分块文件,不需后续的比较。
105、当所述第一传输时间以及第二传输时间的总和大于所述第一使用时间时,将传输第二基站中的第三指定分块文件。
需要说明的是,基站在向用户终端传输某个文件的分块文件时,用户终端可能也在同时使用这个文件,即该文件以下载完的可供用户连续使用的时间在变化。为了不影响用户的使用效果,保证用户使用该传输的文件时的流畅度,在当前传输速率最快的基站传输完上述第三指定分块文件之后,需要保证此时剩余的用户可连续使用 的时间段内仍可以完成上述第二指定分块文件的传输。
106、当所述第一传输时间以及第二传输时间的总和小于所述第一使用时间时,将传输第一基站中的第二指定分块文件。
本发明提供的传输的方法,通过获取用户终端的目标分块文件以及与所述目标分块文件使用顺序相邻连续的已缓存完的分块文件,从而计算出当前用户可以连续使用该文件的剩余时间,然后比较剩余可连续使用的时间与按使用顺序传输下一个传输分块文件的时间以及当前传输速度最快的基站传输下一个未传输的分块文件的时间,根据比较结果确定传输那个分块文件。因此,本发明实施例实现文件传输的过程中,综合考虑到按照使用顺序传输下一个未传输分块文件的时间,保证该分块文件能够在剩余可连续使用的时间内传输完,同时也考虑了存储某个文件的分块文件的若干基站的实时传输的速率,将存储某个文件的分块文件的若干基站采用协调传输的方式,保证了用户使用文件的流程度,提升各个分块文件对应的整体文件的传输速率,减小用户等待时间。
进一步,基于上述方法流程,本发明实施例还提供了另一种可能的实现方式,如图3所示,在执行步骤101获取用户当前使用的目标分块文件以及与所述目标分块文件使用顺序相邻连续的已缓存完的分块文件之前还包括:
107、将文件分成若干分块文件,并按照使用顺序对所述若干分块文件分配标识,其中,使用顺序为第n的分块文件分配第n标识。
当用户终端在若干个基站的覆盖范围共同的覆盖范围内,为了实现若干个基站协作为该用户终端提供文件传输服务,先将整个文件分成L个分块文件,这L个分块文件每一个分块文件都有各自的缓存控制变量q,根据缓存控制变量q的大小将这些分块文件分成两个部分,将缓存控制变量q大于某一指定的值的分块文件存储于移动通信网络中的若干小蜂窝基站中,将缓存控制变量q小于某一指定的值的分块文件存储于移动通信网络的宏蜂窝基站中。其中,缓存控制变量q是分块文件的流行度的衡量指标,缓存控制变量q越 大,该分块文件的流行度越高。
需要说明是的,移动通信网络系统只需要对存储在上述小蜂窝基站中的分块文件分配标识,不需对宏蜂窝基站中存储的分块文件按其使用顺序分块标识。
108、将所述若干分块文件分别随机不重复的存储于指定范围内的若干指定基站的缓存资源中。
其中,指定范围内的若干基站在基站的覆盖范围上存在一种覆盖重叠的关系即必须保证该指定范围内的若干基站存在某一共同覆盖的范围,从而可以保证在这一共同覆盖范围内的用户终端可以通过该若干基站协作完成文件传输。
109、根据指定基站中的分块文件分配的标识,对所述分块文件进行堆栈存储,将分块文件标识小的分块文件保存在所述指定基站的缓存资源的堆栈的前端,分块文件标识大的分块文件存储在指定基站的缓存资源的堆栈的后端。
具体举例说明,假设指定基站中存储着某一整体文件中标识为3、9、11、6的分块文件,按照上述存储方式进行堆栈保存后,该基站的缓存资源中存储这些分块文件的格式如下:3、6、9、11。其中,标识为3的分块文件为该基站缓存资源的栈顶,标识为11的分块文件为该基站缓存资源的栈底。
需要说明的是,越靠近栈顶的分块文件越早传输,也就是说,该基站最先传输的是标识为3的分块文件,其次传输标识为6的分块文件,以此类推,最后传输的标识为11的分块文件。
进一步,为了避免所述基站传输的分块文件重复,保证基站传输的分块文件为未传输的分块文件,基于此目的,本发明实施例还提供了另一种可能的实现方式,该方法的方法流程如图4所示,当所述第一传输时间以及第二传输时间的总和大于所述第一使用时间时,将传输第二基站中的第三指定分块文件之后,该方法还包括以下步骤:
110、将所述传输的指定分块文件移至指定基站中与所述传输的 指定分块文件对应的堆栈的最后,并将指定基站中标识仅小于所述传输的指定分块文件的标识的分块文件转移至堆栈最前端。
为了更加形象描述,具体举例说明,假设某个文件被分成16个分块文件,在某个指定范围内部署4个小蜂窝基站A、B、C、D,并且这4个小蜂窝基站有共同一个覆盖空间。这16个分块文件随机分配到这4个小基站中,假设某一时刻这16个分块文件在4个基站中的存储方式如表1所示,在该时刻后,小基站B将标识为3的分块文件传输给用户终端,传输完该分块文件之后,标识为3的分块文件由B基站的栈顶转移至B基站的栈底,这16个分块文件的存储状态如表2所示。
表1传输标识为3的分块文件前的状态
基站A 5 7 1 2
基站B 3 6 9 11
基站C 4 10 13 16
基站D 8 12 14 15
表2传输标识为3的分块文件后的状态
基站A 5 7 1 2
基站B 6 9 11 3
基站C 4 10 13 16
基站D 8 12 14 15
进一步,不同基站的传输速率不同,并且基站的传输速率是变化的,获取当前传输速率最快的基站中的分块文件时,需要先确定存储着相应文件分块的若干基站当前的传输速率,针对于此,本发明实施例提供了一种可能的实现方式,如图5所示,该方法包括:
201、获取所述各个基站的当前时刻的信道的状态
202、根据所述各个基站的当前时刻的信道状态,确定当前传输速率最快的基站。

可选的是,如图8所示,该装置还包括:
转移单元40,用于将所述传输的指定分块文件移至指定基站中与所述传输的指定分块文件对应的堆栈的最后,并将指定基站中标识仅小于所述传输的指定分块文件的标识的分块文件转移至堆栈最前端。
