实施例1
本发明实施例提供了一种数据获取方法。
图1是根据本发明实施例的数据获取方法的流程图。如图1所示，该数据获取方法包括步骤如下：
步骤S102，接收终端设备发送的标识信息。
具体的，本发明实施例提供的数据获取方法可以适用于由终端设备、基站、鉴权服务器、大数据服务器和内容服务器组成的数据获取系统，其中，图1所示的数据获取方法可以适用于基站侧，在实现本发明实施例提供的数据获取方法时，当基站检测到有终端设备接入所覆盖的范围时，基站接收终端设备发送的标识信息，为实现本发明实施例提供的数据获取方法，基站的类型可以为基站(Base Station，简称BS)、宏基站(Macro Base Station)、微基站(Pico Base Station)、3G移动基站Node B、增强型基站(Evolution Node B，简称ENB)、家庭增强型基站(Femto eNB或HENB)、电子运算处理器(Application Processor，简称AP)、无线路由器、中继站、射频拉远单元(Radio Remote Unit，简称RRU)、射频拉远头(Remote Radio Head，简称RRH)中的一种；
这里终端设备可以为以下至少之一：移动电话机(或手机)，或者其它能够发送或接收无线信号的设备，包括个人数字助理(Personal Digital Assistant，简称PDA)、无线调制调解器、无线通信装置、手持装置、膝上型计算机、无绳电话、无线本地回路(WLL)站、能够将移动信号转换为无线保真(Wireless Fidelity，简称wifi)信号的客户终端设备(Customer Premise Equipment，简称CPE)或便携式宽带无线装置Mifi、智能家电、或其它不通过人的操作就能自发与移动通信网络通信的机器或设备；当终端设备为智能手机时，终端设备发送的标识信息可以包括以下至少之一：可以是智能手机的手机号、客户识别模块(Subscriber Identity Module，简称SIM)卡编号、国际移动用户识别码(International Mobile Subscriber Identification Number，简称IMSI)、移动设备国际身份码(International Mobile Equipment Identity，简称IMEI)、或与智能手机或SIM卡唯一对应的其它编号。
步骤S104，依据标识信息，向预先建立通信连接的鉴权服务器发送鉴权请求，鉴权请求用于判断是否接受终端设备接入当前网络。
具体的，基于步骤S102中接收到的终端设备的标识信息，基站向预先与该基站建立通信连接的鉴权服务器发送鉴权请求，其中鉴权请求除了用于指示鉴权服务器是否接受终端设备接入当前网络外，还用于依据终端设备的标识信息判断终端设备类型或终端设备发送的标识信息为哪一个运营商提供的，以便鉴权服务器将根据该标识信息接入该标识信息对应的运营商所提供的网络中。
例如，假设终端设备中的标识信息为第一运营商提供的SIM卡编号，基站在接收该SIM编号后，将该编号发送至鉴权服务器，鉴权服务器根据该SIM卡编号进行鉴权，得到该SIM卡编号为第一运营商提供，进而将该SIM卡编号对应的终端设备接入由第一运营商提供的网络中。本发明实施例提供的标识信息以SIM卡编号为例进行说明， 以实现本发明实施例提供的数据获取方法为准，具体不做限定，除SIM卡编号外，步骤S102中提供的IMSI、IMEI以及终端设备或SIM卡唯一对应的其他编号中的一个或至少两个的组合均能作为标识信息发送至鉴权服务器，以使得鉴权服务器进行鉴权，其中，鉴权服务器的鉴权方式可以为全球移动通信系统(Global System for Mobile Communication，简称GSM)、宽带码分多址(Wideband Code Division Multiple Access，简称WCDMA)、长期演进型(Long Term Evolution，简称LTE)系统中的鉴权方法，这里对鉴权方法不做限定。
步骤S106，在鉴权结果为是的情况下，接收大数据服务器发送的对应标识信息的偏好数据。
具体的，结合步骤S104，当基站得到的鉴权服务器的鉴权结果为是时，基站接收大数据服务器发送的对应标识信息的偏好数据。其中，对应标识信息的偏好数据可以为终端设备常用的应用程序软件包信息，或者，依据终端设备的历史浏览记录得到的数据权重，该数据权重可以用于指示终端设备常被用于显示的网络媒体数据类型，名称等信息；或者，该历史信息还可以为该终端设备常用于显示的网络媒体数据的统一资源定位符(Uniform Resource Locator，简称URL)，该URL可以表示为该终端设备所访问的网址。
步骤S108，依据偏好数据生成数据请求，数据请求包括以下至少一种：终端设备的标识信息、基站的标识信息。
具体的，基于步骤S106中基站接收到的大数据服务器发送的对应标识信息的偏好数据，生成用于向内容服务器获取网络媒体数据的数据请求，其中，数据请求可以携带终端设备的标识信息，或，携带了分别对应基站与终端设备的标识信息。
这里数据请求可以为以下两种形式：
方式一，数据请求中携带终端设备的标识信息；
基站为了减少发送数据请求时产生的数据量，仅将该终端设备的标识信息封装至数据请求，从而使得内容服务器能够依据该标识信息提供对应该标识信息的网络媒体数据；此时，可以通过其它方式确定该基站的标识以便将对应该标识信息的网络媒体数据发送至该基站，例如连接基站与内容服务器的路由器或其它网络设备来确定，或者在数据请求之后的后续流程中交互基站的标识信息，等等。
方式二，数据请求中分别携带终端设备和基站的标识信息；
若基站将自身的标识信息与终端设备的标识信息同时封装至数据请求，能够使得内容服务器在依据终端设备的标识信息提取对应的网络媒体数据外，依据基站的标识信息能够获知该网络媒体数据是由哪个基站请求的，能够使得内容服务器在依据数据请求时针对基站的标识信息，将该网络媒体数据返回至该基站，以便基站将该网络媒体数据在终端设备发送网络媒体数据请求时，将该网络媒体数据发送至终端设备。
步骤S110，向内容服务器发送数据请求，数据请求用于获取偏好数据对应的网络媒体数据。
具体的，在步骤S108依据偏好数据生成数据请求，向内容服务器发送该数据请求，这里依据偏好数据生成数据请求中的偏好数据以步骤S108中提供的URL为例进行说明，若向内容服务器发送该数据请求可以理解为：基站依据该URL访问内容服务器，提取对应该URL的网络媒体数据。
步骤S112，接收内容服务器依据数据请求返回的网络媒体数据。
其中，基站接站接收到的内容服务器依据数据请求返回的网络媒体数据可以为以下至少一种：视频、音频、文字、图片。
步骤S114，缓存网络媒体数据。
具体的，基于上述步骤S112，基站接收内容服务器依据数据请求范围的网络媒体数据，基站将该网络媒体数据进行缓存，以使得当终端设备发起对网络媒体数据请求时，基站可以直接从缓存的网络媒体数据中进行提取，省去了在接收到终端设备发送的对网络媒体数据请求后，基站仍需向大数据服务器以及内容服务器进行数据请求的过程，提升了数据获取效率。
这里本发明实施例提供的鉴权服务器、大数据服务器、内容服务器可以为一个服务器中的对应的鉴权功能的模块、大数据匹配模块以及内容提取模块，还可以为一个服务器集群中具备鉴权功能的服务器、大数据服务器和提取网络媒体数据的内容服务器，本发明实施例仅以鉴权服务器、大数据服务器和内容服务器为例进行说明，以实现本发明实施例提供的数据获取方法为准，具体不做限定。
本发明实施例提供的数据获取方法，通过接收终端设备发送的标识信息；依据标识信息，向预先建立通信连接的鉴权服务器发送鉴权请求，鉴权请求用于判断是否接受终端设备接入当前网络；在鉴权结果为是的情况下，接收大数据服务器发送的对应标识信息的偏好数据；依据偏好数据生成数据请求，数据请求包括以下至少一种：终 端设备的标识信息、基站的标识信息；向内容服务器发送数据请求，数据请求用于获取偏好数据对应的网络媒体数据；接收内容服务器依据数据请求返回的网络媒体数据；缓存网络媒体数据，解决了由于时延较大，导致在移动通信服务过程中耗时过长，降低了通信效率的问题，达到了提升通信效率的效果。
基于上述步骤S102至步骤S114提供的数据获取方法，由于上述偏好数据是经过对终端设备的历史浏览记录分析得到的，该终端设备将会有大概率会访问上述偏好数据，因此本发明实施例提供的数据获取方法使得从用户操作终端设备打开终端设备中安装的应用程序并获取对应的历史浏览记录开始就能很快从基站直接获取对应的网络媒体数据，能够明显降低了终端设备获取网络媒体数据的时延，提升数据获取效率。由于鉴权、获取终端设备的偏好数据、数据缓存的操作都是基于该终端设备对应的标识信息(例如上面提到的IMSI)，用户本人无需参与(不需要像Wifi一样需要选择Wifi节点并输入用户名和密码等)，从而节省了输入选取过程。此外，本发明实施例提供的数据获取方法还可以应用于机器到机器(Machine to Machine，简称M2M)通信中；对于M2M通信来说，通信的双方都是机器，如果通过Wifi等方式进行通信的话，需要内置Wifi的SSID和密码，或者进行其他鉴权操作或配置才行；而使用了本发明实施例提供的数据获取方法，只要机器中包括有SIM卡或者SIM卡等效的装置或信息，就可以不需人为参与就可以自动实现M2M通信，例如包括有某公司传感器的机器通常会在每天固定时候访问该公司的服务器获取数据，使用本发明实施例提供的数据获取方法就可以根据大数据分析的结果、从该公司的服务器获取内容并提前缓存到基站的存储空间中，当该固定时间到达，该机器就可以快速地与基站完成通信，此时还能降低该通信对无线资源的占用，从而避免了大量的M2M终端在同一时刻向服务器请求数据造成的延时大、网络拥塞的可能问题。此外，本发明将移动通信系统中的标识信息(例如IMSI、SIM卡相关信息等)作为获取其它信息的凭证，从而无需用户手动输入用户名和密码就可以自动获取这些信息，并且还可以使缓存的内容也具备移动性，例如用户更换了该标识信息的终端(例如用户将SIM卡从第一手机取出并插入第二手机，或将SIM卡从手机取出并插入平板电脑等等)，基站仍然会缓存该标识信息对应的内容。进一步，本发明的核心是基站，具有较高的智能性，能够与大数据服务器、内容服务器直接通信并将内容缓存在基站(接入设备，并非移动通信系统的核心网设备)，也就是最接近UE的设备，比其它现有技术能更好地降低UE获取内容的时延。
在本发明实施例提供的数据获取方法中，一旦终端设备向基站发送对该基站所存储的网络媒体数据的访问请求，基站就将所存储的网络媒体数据发送给终端设备。也即是，终端设备向基站发送的访问请求包括待访问的内容的地址，在现有技术中，基站会根据该访问请求访问相应地址并获取网络媒体数据再发送给UE；而在本发明实施 例提供的数据获取方法中，基站收到终端设备的访问请求之后，若判断终端设备欲访问的网络媒体数据已经缓存在基站的存储空间，则直接从存储空间获取网络媒体数据再发送给终端设备，从而使该终端设备对该网络媒体数据的访问得到加速，提高了数据的获取效率，降低了终端设备与基站、基站与服务器间的访问时延的出现几率。
相比现有相关技术中由于时延较大，导致在移动通信服务过程中耗时过长，降低了通信效率的问题，本申请提供的方案达到了降低耗时，提升通信效率的效果。
本发明实施例提供的数据获取方法中，在步骤S106接收大数据服务器发送的对应标识信息的偏好数据时，存在以下方式：
方式一，通过鉴权服务器的鉴权成功指示，向大数据服务器发送对应标识信息的偏好数据请求，从而接收对应该偏好数据请求的偏好数据。具体如下：
作为优选的实施例，步骤S106中接收大数据服务器发送的对应标识信息的偏好数据的步骤包括：
步骤S1061，接收鉴权服务器发送的鉴权成功指示；
具体的，基站接收由鉴权服务器发送的鉴权成功指示，通过该鉴权成功指示使得终端设备通过基站与网络建立通信连接，并对终端设备提供对应的通信服务。
步骤S1062，依据鉴权成功指示生成偏好数据请求；
具体的，结合步骤S1061在接收到鉴权服务器发送的鉴权成功指示后，依据该鉴权成功指示生成偏好数据请求，该偏好数据请求用于向大数据服务器请求终端设备对应的偏好数据。
步骤S1063，向大数据服务器发送偏好数据请求；
其中，基于步骤S1062生成的偏好数据请求，基站将该偏好数据请求发送至大数据服务器。
步骤S1064，接收大数据服务器依据偏好数据请求返回的偏好数据。
具体的，基站接收的大数据服务器返回的偏好数据可以为该标识信息对应的历史浏览记录，或，依据该历史浏览记录由大数据服务器计算得到的对应该标识信息的浏览数据权重，或，与该浏览数据权重向同或相似的偏好数据，即，预测该标识对应的终端设备将显示的网络媒体数据类型、名称，具体可以表现为该标识信息对应的终端 设备上常用于显示的网络媒体数据类型和名称，例如，历史浏览记录可以为：在某月的10号至15号，晚8:00至10：00，使用该终端设备显示视频、该视频为电视剧、该电视剧的名称为《XXXX》，以此为例，基站接收到的偏好数据可以为大数据服务器根据上述信息进行大数据分析之后确定的数据。具体如表1示出了输入大数据服务器的用户的历史浏览记录信息的例子：
表1：
Figure PCTCN2015079306-appb-000001
其中，如表1所示，可以为大数据服务器获取的偏好数据，即X月10日至15日晚上20:00～22:00使用平板电脑或智能手机(使用同一个标识信息，例如SIM卡)观看名为《XXXX》的视频的历史浏览记录。由此可以得出使用了该标识信息的终端设备为智能手机时，很可能在16日之后仍旧在上述日期、时间观看名为《XXXX》的视频，从而大数据服务器向基站发送的该用户对应的偏好数据即是名为《XXXX》的视频的信息，基站收到之后再根据该信息向内容服务器请求该信息对应的视频，内容服务器就在16日的20:00之前、将《XXXX》的视频发送给基站。
或者，基站接收的大数据服务器返回的偏好数据可以为依据该历史浏览记录由大数据服务器计算得到的对应该终端设备的浏览数据权重，该权重可以为如下两种情况：情况一，显示终端设备显示网络媒体数据的习惯；情况二，展示终端设备可能会显示的网络媒体数据；具体如下举例：
情况一，假设终端设备的历史浏览记录为在1号至15号均播放电视剧《某某故事》，24次；在上述日期内播放了8次多部喜剧类电影：电影1、电影2、电影3、电影4、电影5、电影6、电影7和电影8；新闻和视频短片在上述日期播放了7次；以权重值为10做最高值，因此可以得到如下权重：
1号至15号，电视剧《某某故事》的权重值可以设定为8；
喜剧类电影的权重值可以为7；
新闻和视频短片的权重值可以分别为5；
若基站从大数据服务器获取如上述权重值，则在向内容服务器发送偏好数据请求后，内容服务器返回的网络媒体数据可能会是《某某故事》的后续电视剧集数、终端设备未播放过的喜剧类电影以及新闻和视频短片中的一种或至少两种的组合；其中，当内容服务器返回的网络媒体数据为一种时，内容服务器可以以依据权重值最大的网络媒体数据作为标准，获取该网络媒体数据，并发送至基站。
情况二，仍旧以情况一的假设为例，若基站从大数据服务器获取上述权重值，则在向内容服务器发送偏好数据请求后，内容服务器可以依据上述权重值，对权重值最大的网络媒体数据获取相关的网络媒体数据，并将该相关的网络媒体数据发送至基站，例如，电视剧《某某故事》，内容服务器在获知该电视剧的权重值为8，且为最大权重值，因此在获取网络媒体数据时除获取《某某故事》外，还可以获取《某某故事》第二季、《某某故事》第三季；
或者，依据情况一中的权重值，分别对电视剧《某某故事》匹配提取同类型的电视剧；
对喜剧类电影匹配提取同类型电影得到：电影9、电影10……；
对1号至15号新闻提取当天新闻；
对视频短片匹配提取同类型的视频短片。
除此之外，若基站向大数据服务器发送的偏好数据请求中携带有终端设备的设备类型，则大数据服务器可以依据该偏好数据请求，向基站返回对应终端设备类型的偏好数据，该偏好数据在基站向内容服务器发送数据请求后，可以用于指示内容服务器针对终端设备类型提取对应的网络媒体数据，假设终端设备为智能手机，该智能手机既能显示蓝光品质的视频也可以显示1080p的视频，还可以显示780p的视频，但是针对上述类型视频品质的不同，视频的数据大小也会不同，且该数据大小依次降低，由此可知在保障智能手机播放视频的情况下，780p的视频由于数据小，不会对信道的数据传输产生大的压力，由此则可以避免在数据传输过程中由于没有针对终端类型而传输的数据过大，使得对信道的数据传输造成了传输压力，降低了数据传输速率的问题，相反，若针对终端设备类型获取对应的网络媒体数据，则可以降低信道的数据传输压力，提升数据传输速度。
结合上述步骤S1061至步骤S1064接收偏好数据的过程，基站依据鉴权服务器发送的鉴权成功指示向大数据服务器请求偏好数据的过程可以为：鉴权服务器向基站发送鉴权成功指示，其中，该鉴权成功指示包括：大数据服务器的标识信息(例如大数据服务器的IP地址等)，基站就可以根据大数据服务器的标识信息向大数据服务器发送该终端设备的标识信息，从而使得大数据服务器根据该终端设备的标识信息获取该终端设备的偏好数据，并将该偏好数据返回给基站；或者，该大数据服务器的标识信息提前存储在基站侧，基站就可以直接向大数据服务器请求该UE的大数据信息。
其中，偏好数据请求中可以包括终端设备和基站的标识信息。这里的标识信息可以不仅限制与终端设备的标识信息。
这里，本发明实施例提出了智能基站，该智能基站不仅实现了传统基站的基本的无线接入的功能，还可以主动与大数据服务器通信，从而更好地降低延时。
方式二，直接接收大数据服务器发送的偏好数据。具体如下：
作为优选的实施例，步骤S106中接收大数据服务器发送的对应标识信息的偏好数据的步骤包括：
接收大数据服务器发送的偏好数据，偏好数据为在鉴权服务器鉴权结果为是的情况下，鉴权服务器指示大数据服务器发送对应标识信息的偏好数据。
其中，区别于方式一中需要向大数据服务器发送偏好数据请求的方法，进一步获取偏好数据的过程，方式二中提出了在鉴权服务器对终端设备的标识信息鉴权成功后，鉴权服务器与大数据服务器通过预先建立的通信连接进行通信，将该终端设备鉴权成功的信息发送至大数据服务器，指示大数据服务器可以向基站发送对应该终端设备的偏好数据，其中，鉴权服务器发送至大数据服务器的鉴权成功信息可以携带该终端设备的标识信息。
基于上述接收大数据服务器发送的偏好数据的过程具体可以为：鉴权服务器向大数据服务器发送该终端设备的标识信息(例如当该终端设备为智能手机时，智能手机的手机号、IMSI、IMEI、IP地址等)和/或基站的标识信息(例如基站的IP地址等)，大数据服务器就根据终端设备的标识信息获取其中存储的该终端设备对应的偏好数据，再将该偏好数据发送给基站。
除此之外，本发明实施例提供的数据获取方法中，在接收大数据服务器发送的偏好数据中还包括：
在本发明中，基站还可以具有智能性，一旦基站与鉴权服务器对终端设备鉴权通过，则基站就主动向大数据服务器发送对该终端设备对应的偏好数据的请求，而不需等待终端设备或者其它设备发送任何请求来触发，这样能够快速获取所需要缓存的网络媒体数据。具体地，基站可以根据提前存储在基站内部的或者由其它网络设备(例如归属用户服务器(Home Subscriber Server，简称HSS)或其它网管设备)发送的偏好数据(例如其编号、IP地址等)确定该偏好数据的访问地址，并向内容服务器发送数据请求，再从该内容服务器获取网络媒体数据。
作为优选的实施例，在步骤S114缓存网络媒体数据之后，本发明实施例提供的数据获取方法还可以包括：
步骤S116，检测终端设备是否处于连接状态；
具体的，基站检测终端设备是否与自身处于连接状态，可以通过周期性的检测信令，检测是否存在终端设备返回的对应检测信令的响应反馈；还可以通过其它方式，例如判断该终端设备是否处于LTE标准规范所定义的RRC_idle状态并超过预定的时间，等等。
步骤S118，当检测到的终端设备的连接状态为断开时，执行断开后的处理操作；
具体的，当基站检测到终端设备的连接状态为断开时，基站执行在断开后的操作，即，基于上述步骤S116中，若基站没有接收到终端设备反馈的对应检测信令的响应反馈，或者该终端设备处于RRC_idle状态并超过预定的时间，等等，则判断该终端设备与基站的连接断开。
其中，具体如何执行步骤S118中的处理操作，可以为以下至少一种方式：
方式一，删除标识信息对应的偏好数据和/或对应偏好数据的网络媒体数据；
具体的，本发明实施例提供数据获取方法主要应用于移动通信系统中，由于终端设备具有移动性，因此终端设备很可能移动离开当前基站的覆盖区域，例如终端设备切换到其它基站的覆盖区域；此外也可以存在其它终端设备与基站失去连接的情况，例如终端设备电池耗尽，或者终端设备发生故障等。此时，若基站检测到该终端设备离开当前基站的覆盖区域，基站就删除该标识信息对应的偏好数据和/或网络媒体数据，以便于存储其它终端设备的标识信息对应的偏好数据和/或网络媒体数据。
除此之外，本发明实施例提供的标识信息除表示终端设备中SIM卡、IMSI码或IMEI码之外，还可以用于表示终端设备的唯一机器编码或编号，本发明实施例仅以上 述SIM卡、IMSI码或IMEI码中的一种或至少两种的组合为例进行举例，以实现本发明实施例提供的数据获取方法为准，具体不做限定。
方式二，当检测到终端设备由当前基站接入至第一基站时，将标识信息对应的偏好数据和/或对应偏好数据的网络媒体数据发送至第一基站；
具体的，当终端设备切换到其它基站覆盖区域时，基站将该终端设备的偏好数据发送给第一基站，这样就避免第一基站再向大数据服务器请求该终端设备的偏好数据的过程。其中，当前基站与第一基站可以建立通信连接(例如LTE标准规范中所定义的X2接口或S1接口，或者直接是因特网的连接等等)，以使得在终端设备由该当前基站移动至第一基站覆盖的范围时，当前基站能够将该终端设备的偏好数据和/或网络媒体数据发送至第一基站，这里第一基站可以为一个或多个基站，本发明实施例以实现数据获取方法为准，具体不做限定。
方式三，当检测到终端设备由当前基站接入至第一基站时，依据终端设备驻留在当前基站下的历史浏览记录，修改标识信息对应的偏好数据和/或对应偏好数据的网络媒体数据；
将修改后的偏好数据和/或对应偏好数据的网络媒体数据发送至第一基站。
具体的，在本发明实施例提供的在断开连接后基站的执行操作过程中，基站还可以具有大数据计算功能，从而能够修改标识信息对应的偏好数据；例如，该终端设备在该基站的覆盖区域长时间访问了XX视频网站，则基站可以将XX视频网站对应的标识信息添加到该终端设备的偏好数据中，并发送给大数据服务器更新对应该终端设备的偏好数据；或者，在终端设备切换到其它基站覆盖区域时，将对应该终端设备的修改后的偏好数据发送给其它基站更新，便于其他基站为用户提供更新后的缓存服务。
上述三个方式具有多方面的好处，具体如下：一方面，本发明实施例提供的数据获取方法中基站缓存网络媒体数据之后的步骤，将大数据计算功能放在基站侧，减少了大数据服务器或其它网络设备的复杂度；另一方面，该方法还可以降低基站向网络反馈的数据量，例如基站可以不用向其它网络设备发送大量的终端设备的通信行为信息，而只反馈偏好数据的更新信息即可，从而减少了基站的反馈量；此外，该方法对于使用local breakout(本地分流)方法的基站来说尤为重要。对于传统的移动通信网络来说，基站连接到核心网(包括S-GW、P-GW、MME等设备)，终端设备通过基站进行的所有通信内容都需要经过核心网连接，从而能够便于对终端设备的通信内容进行计费；而对于具有小覆盖区域的小基站来说，例如小基站部署在通信热点地区，在这些地区的通信流量通常很大，按照传统的方式连接可能会导致核心网压力较大，因 此提出本地分流的方法，即小基站直接连接到因特网，从而终端设备通过小基站访问的内容就不需经过核心网连接，就减少了对核心网的压力；因此，对于使用了本地分流技术的系统来说，用户的通信内容是不会经过核心网，由基站来进行偏好数据分析，并更新终端设备的偏好数据就能够同样避免数据再经过大数据服务器而导致的传输延时，还能够减轻在数据传输过程中步骤的复杂度。
