Description

网页页面预读方法、中转服务器和网页页面预读***
本发明涉及移动互联网领域，更为具体地，涉及一种网页页面预读方法、中转服务器以及具有该中转服务器的网页页面预读***。
随着社会的进步和技术的发展，人们越来越多地使用移动终端来以无线的方式接入网络来获取信息。在普通的页面浏览流程中，用户在当前页面点击前进到链接页面，即时加载，但对于目前的通过移动终端尤其是手机上网方式来说，由于终端硬件以及网络接口的限制，在点击了加载前进页面后到加载完成之前，用户难免有十到二十秒的等待网页加载过程，这个过程将浪费一定用户时间，消耗用户的耐心。针对这种情况，网页的预读技术逐渐得到广泛的应用。
技术问题
关于网页的预读，现有技术中存在的普遍做法如下：
服务器基于客户端终的用户历史浏览行为和网页排版预测哪些文件需要被预先装载，当用户进行网页浏览的时候根据所预先装载的文件实现网页的预读功能，这样，用户就不需要等待网页加载的过程而很快地从服务器获得需要加载的页面内容。
美国US7284035(B2)号专利申请中就披露了类似的技术方案：决定网页的某些特定子页被用户获取，如果决定了就优选预读这些被确定的子页，对子页的偏好通过分析用户之前访问的网页来产生，这种分析所参考的因素包括某个用户对某一网页的子页的访问历史、访问过去的天数、在本页中有多少个子页等等。例如，当一个用户每天早上访问同一个新闻网站并总是阅读政治、计算机、旅游和阅读栏目的文章的时候，根据该专利，则当新闻网页被访问时，这些喜好将会被决定，而那些与政治、计算机、旅游和阅读栏目的文章将被比其他栏目更加优先的被加载入浏览器的缓存。
但是，上述现有技术对特定子页的预读，用户仍需要进行子页的翻页操作才能从客户端的缓存中逐一获得这些子页，对于需要浏览含有多个子页的网页（如连载小说）的用户来说，虽然预读能够在一定程度上缩短用户的等待时间，但频繁的翻页操作也会给连续的浏览体验带来不便。
申请号为200910313007.8的中国专利提出了一种用于移动通讯设备终端的网页页面预读及整合浏览***及其应用方法，采用预先操作读取当前网页的子页并保存的预读模块和用于把当前网页和子页组合成一个组合网页的网页组合模块，并对预读页面进行多层搜索，将对获取的子页与当前页面进行重新组合成一个统一的网页显示给用户，提高用户的浏览感受。
但申请号为200910313007.8的中国专利所提出预读整合方案只是简单地以网页上的如“下一页”/“下一章”/“下一节”关键词为激发预读的热点进行相应子页的获取和组合，对于含有复杂子页结构的网页（如连载小说中同时存在“下一页”和“下一章”链接的情形）来说无法进行精确的预读，并且该申请号为200910313007.8的中国专利预读的规则单一，缺乏对用户浏览喜好的考虑，友好性较差。

 本发明的实施方式
以下将结合附图对本发明的具体实施例进行详细描述。
为了能够灵活地获取有效的子页并对所获得的子页进行合并重排处理，本发明采用基于关键字的优先级和用户行为的多子页合并预读方案，并且把预读的操作和重排版及合并处理放在中转服务器中处理，仅将网页渲染显示的最后步骤放到客户端，以最大化地减轻移动通讯设备终端的负担。
需要说明的是，在对本发明技术方案的表述中，网页的子页是相对于用户浏览的当前页面来说的，具体的可以是当前浏览页面中超链接所指向的其他页面，比如下一页等。
另外，本发明采用客户端-服务器的基本构架，虽然本发明主要是针对以移动终端作为网页浏览客户端来设计的，但也不排除将本发明应用到除手机等移动终端之外的接入性客户端，如PC、特定服务提供终端（如机场、车站的查询终端）等，因此，在下文的表述中，“移动终端”、“终端”、“客户端”等表述均指与用户直接交互的接入性客户端。
图1示出了根据本发明的基于中转服务器的网页页面预读方法的流程图。
如图1所示，当移动终端用户浏览网页页面时，移动终端即将用户的网页页面访问提交给中转服务器，而中转服务器则根据移动终端的页面访问请求向相应的网络资源服务器请求相应的页面数据（S110）；在中转服务器收到从网络资源服务器返回页面数据后，从所获取的该页面的页面数据开始，执行下述预读过程，直到从所述网络资源服务器预读该页面的预定层数的子页面的页面数据：对当前从所述网络资源服务器返回的页面数据或预读的子页面数据进行预读关键字分析，以获得所述当前返回的页面数据或子页面数据中包含的预读关键字；根据所述获得的预读关键字中的具有最高优先级的预读关键字，从所述网络资源服务器预读该当前页面或子页面的下一子页面的页面数据（步骤S120）。具体地，例如，在一个示例中，如图2所示，首先，对从网络资源服务器返回的页面数据进行预读关键字的分析（S121）；然后根据所获得的预读关键字的优先级从网络资源服务器获取所请求页面的子页面的URL（S123）；在获取到子页面的URL之后，中转服务器根据所述获取的URL，从所述网络资源服务器预读要预读的子页面的页面数据（S125），然后，在步骤S127，判断是否已经经过预定层数的子页面页面数据预读。如果没有经过预定层数的子页面页面数据预读，则返回到步骤S121，在步骤S121，对当前预读的子页面的页面数据进行预读关键字分析。随后重复执行步骤S121到S127的处理，直到在步骤S127判断为已经进行预定层数的子页面页面数据预读为止。这里，所述预定层数可以根据终端的硬件配置确定，也可以由用户自主设定。在预读层数的控制方面，可以通过计数器或者其他本领域技术人员所悉知的数量控制方式来实现。
在预读完规定层数的子页面之后，中转服务器就对所述预读出的预定层数的子页面进行合并重排（S130）；最后将合并重排后的组合页面数据发送给移动终端（S140），从而实现对用户所需要的网页页面预读及整合浏览。
通过上述中转服务器对用户请求的网页的子页进行的预读及整合浏览的处理，用户在点击当前浏览页面上的上述根据预读关键字的优先级所确定的关键字或最常访问页面链接的时候，移动终端就能够直接调取缓存中多子页合并后的预读页面进行显示，从而不需要任何的翻页操作就能够浏览到适当数量的子页内容。
其中，预读关键字的优先级从左到右，依次降低：
下页、[下页]、下一页、[下一页]、下页|、>>下页、>>下页|、下一张、[下一张]、[->]、>、[>]、[->>]、>>、[>>]、下章、[下章]、下一章、[下一章]、下节、[下节]
中转服务器在判断网页上关键字的优先级的过程中，选取优先级最高的关键字，将该关键字链接指向的网页的子页及该子页的同一关键字链接指向的子页等都保存下来，例如一篇新闻的首页只有新闻的摘要内容，该页面的最高优先级关键字是“下页”，该新闻的正文一共有5页，且每一页的下方都有关键字“下页”，则中转服务器会将该新闻的第2页到第5都作为首页的子页进行预读。
除了上述关键字优先级的引入，在本发明的一个优选实施方式中，还将海量用户行为纳入预读的考虑因素之中，即在步骤S123获取了子页面的URL之后，进一步判断所述子页面的URL与根据海量用户行为统计得到的在访问所述页面之后最常访问的页面URL是否相同，如果相同，则继续步骤S125的预读流程；如果不相同，则根据所述最常访问的页面URL的跳转访问率，确定是否预读所述最常访问的页面。
如果所述跳转访问率超过预设阈值，则根据所述最常访问的页面URL，预读所述最常访问的页面；否则，如果所述跳转访问率没有超过预设阈值，则不进行任何预读操作。
在本发明的技术方案中，中转服务器的海量用户行为统计就是记录所有用户的访问行为，并基于这些行为的记录得出与用户的访问行为相关的额各种统计参数，例如访问频率（即一天访问多少次）、某页面跳转到另外一个页面的几率等，这些都是基于用户的访问行为记录统计出来的。
具体来说，根据海量用户对上述子页的历史访问行为的统计数据得到该网页被访问之后最常被访问的网页（其中包括该网页的子页以及其他跳转的网页），如果根据关键字优先级预读到的子页的URL和该网页被访问之后最常被访问的网页的URL是一样的，则可以判定用户很希望对该新闻进行连续阅读，于是将根据关键字预读到的所有子页进行合并重排处理后发送到移动终端进行缓存。
组合的子页数量可以根据终端的硬件配置确定，也可以由用户自主设定，但考虑到用户的浏览习惯和大多数移动终端的终端配置，组合的子页数一般不超过四层，优选地对2～3层的子页进行合并重排。
如果根据关键字优先级预读到的子页和该网页被访问之后最常被访问的网页是不同的，则根据海量用户的历史访问行为的统计数据判断该网页被访问之后最常被访问的网页的跳转访问率来确定是否进行跳转访问的预读。该跳转访问率可根据经验值设定，如60%～80%之间的数值。在本发明的一个具体实施方式中，如果这个网页的跳转访问率达到70%，就对最常被访问的网页进行预读，如果这个网页的跳转访问率没有达到70%，则不进行任何后续预读。
这种海量用户行为统计信息的比较判断可以在仅第一层子页面的预读过程中引入，也可以在每一次子页面的预读过程中均将子页面的URL与海量用户行为统计得到的跳转页面URL进行比较，以使得中转服务器所预读的每一页面都更加贴近用户的浏览需求。
具体的，作为示例，在每一次子页面的预读过程中均将子页面的URL与海量用户行为统计得到的跳转页面URL进行比较的过程如下：在每次获取一个子页面的URL之后，都判断该子页面的URL与根据海量用户行为统计得到的在访问该子页面的上一页面之后最常访问的页面URL是否相同，如果相同，则继续上述步骤S125的预读操作；否则根据海量用户行为统计所确定的最常访问的页面URL的跳转访问率确定是否预读该最常访问的页面。同样，如果该跳转访问率超过预设阈值，则根据最常访问的页面URL预读所述最常访问的页面；如果所述跳转访问率没有超过预设阈值，则不进行任何预读操作，仅就已经预读的子页面进行合并重排处理。
下面以两个具体的实施方式来对本发明提供的上述基于中转服务器的网页页面预读及整合浏览方法做示例性说明。
实施例一
在网页的版面编排设计方面，对基于同一内容的各子页说来，它们的页面结构都是一样的：使用相同的标记语言，相同的网页标题等等，因此就可以根据这一特点来对子页的内容进行组合重排。具体来说，就是把网页根据网页标记语言分成标题部分和正文部分，把各子页的正文部分内容抽取，并组合成新组合网页的正文部分，新组合网页的标题部分采用各子页标题的相同部分，用户浏览时直接输出组合后的整页内容即可。
图3为对相同结构的子页进行组合重排的简单结构示意图。如图3所示，假设用户当前浏览的页面为Pagef，其各子页分别为子页1、子页2、子页3和子页4。
子页1的正文部分为text01，标题为abc1；
子页2的正文部分为text02，标题为abc2；
子页3的正文部分为text03，标题为abc3；
子页4的正文部分为text04，标题为abc4；
中转服务器通过预读将子页1到子页4获取并保存后，经过海量用户行为统计后发现，在用户访问历史行为统计中对当前浏览的页面为Pagef进行访问完之后，最常被访问的页面就是子页1，因此就可以将pagef所有子页合并重新排版成组合网页5。
如图3所示，在组合重排后，组合网页5的正文部分为子页1，子页2，子页3和子页4的正文部分的结合，因此组合网页5的正文部分为：text01，text02，text03和text04的连续组合；组合网页5的标题为子页1，子页2，子页3和子页4的标题的相同部分，即为abc。组合完成之后，中转服务器将该组合重排后的网页5发送给客户端。
当用户点击当前页面pagef上的超链接“下一页”时，客户端将组合网页5进行渲染显示。这样，客户不必进行繁琐的翻页操作即可获得与当前页面相衔接的更多的浏览内容，从而获得更好的浏览体验。
实施例二
对于涉及网络连载小说的网页来说，由于小说的章节需要，网页上能激发预读操作的链接不仅“下一页”，还可能会同时存在“下一节”、“下一章”甚至“下一卷”的情形，对于这种多个预读热点关键字同时存在的情况，就需要首先对该网页上关键字的优先级进行判断。
比如在某网络小说的网页中，“下一页”的优先级“下一章”的优先级高，而“下一章”的优先级又会高于“下一卷”的优先级。假如用户现在正在读第二章第1页（假如第二章一共有7页），那么中转服务器就会根据关键字的优先级，在获得第二章第1页之后，预读第二章第2页到第7页，然后分析所有用户当浏览完第1页后通常最常访问的那个页面（海量用户行为统计），如果该最常访问的页面是第2页，那么就将这7页的内容或者第2页到第4页的内容进行合并重排处理并发送给移动终端的缓存，当用户点击当前网页上的关键字“下一页”时，移动终端直接调取合并后的页面缓存数据进行显示。如果中转服务器根据分析，发现所有用户当浏览完第1页后最常访问的那个页面不是第2页，而是最后一章的倒数第3页，那么中转服务器将对最后一章的倒数第3页以及第3页后的若干子页进行预读，直至预读的子页数量达到规定层数，然后中转服务器将所预读的所有页面进行合并重排处理并发送给移动终端。如果中转服务器根据分析，发现所有用户当浏览完第1页后都最常访问的那个页面不是第2页，也是不该小说的任何一页，而是另外一个内容不相关的页面，且从该网络小说的页面链接到该内容不相关的页面的跳转访问率高达70%，则中转服务器将预读该内容不相关的页面及其子页，并进行页面合并重排处理后发送给移动终端。
在本发明中，进行合并处理时通常考虑到子页之间的相似程度，可以通过判断子页URL的方式进行各种合并重排，当然也可以通过判断子页排版的相似程度进行合并重排。
在本发明的预读逻辑中，有基于关键字的预读和基于统计（海量用户行为统计）的预读两种。按照一般的逻辑，针对关键字的预读的优先级大于基于统计的预读的优先级，在上述对本发明技术方案的表述中，都是针对有关键字的预读，也就是说，对于有预读关键字的页面，优先预读关键字；没有预读关键字的页面，根据中转服务器的海量用户行为统计结果进行预读。
如上参照图1和图2描述了根据本发明的基于中转服务器的网页页面预读及整合浏览方法。本发明的上述基于中转服务器的网页页面预读及整合浏览方法，可以采用软件实现，也可以采用硬件实现，或采用软件和硬件组合的方式实现。
与上述方法相对应，本发明还提供了一种用于网页页面预读及整合浏览的中转服务器，图4示出了根据本发明的用于网页页面预读的中转服务器400的方框示意图。如图4所示，用于网页页面预读的中转服务器400包括接收单元410、预读关键字分析单元420、页面预读单元430、判断单元440、预读页面组合单元450和发送单元460。
其中，接收单元410用于从移动终端接收针对具有多个子页面的页面的页面数据的页面访问请求，以及响应于所述页面访问请求，从网络资源服务器接收所请求的页面的页面数据。
预定关键字分析单元420用于对当前从所述网络资源服务器返回的页面数据或预读的子页面数据进行预读关键字分析，以获得所述当前返回的页面数据或子页面数据中包含的预读关键字。页面预读单元430用于根据所述获得的预读关键字中的具有最高优先级的预读关键字，从所述网络资源服务器预读该当前页面或子页面的下一子页面的页面数据。所述判断单元440用于判断是否已经预读预定层数的子页面的页面数据。其中，在从所述网络资源服务器获取该页面的页面数据后，从所获取的该页面的页面数据开始，重复执行所述预定关键字分析单元420和页面预读单元430的处理，直到所述判断单元440判断为已经从所述网络资源服务器预读该页面的预定层数的子页面的页面数据。预读页面组合单元450用于对所述页面预读单元预读的所有预定层数的子页面的子页面数据进行合并重排。发送单元460将经过合并重排后的组合页面数据发送给移动终端。
在本发明的一个示例中，如图5所示，所述页面预读单元430还可以包括：URL地址获取模块431，用于根据所述预读关键字分析单元获得的预读关键字中的具有最高优先级的预读关键字，从所述网络资源服务器获取该要预读的子页面的URL地址；以及页面数据获取模块433，用于根据所述获取的URL地址，从所述网络资源服务器预读要预读的子页面数据。
在预读关键字分析单元420中，所设定的预读关键字的优先级从高至低依次为：下页、[下页]、下一页、[下一页]、下页|、>>、下页、>>下页|、下一张、[下一张]、[->]、>、[>]、[->>]、>>、[>>]、下章、[下章]、下一章、[下一章]、下节、[下节]。
结合图4和图5，中转服务器逐层预读子页面的过程如下：在页面预读单元430中的页面数据获取模块433根据子页面的URL和预读关键字的优先级从网络资源服务器预读第一层子页面之后，预读关键字分析单元420进一步分析第一层子页面并获得该第一层子页面上包含的预读关键字，然后，页面预读单元430中的页面数据获取模块431根据预读关键字的优先级从网络资源服务器获取第一层子页面的下一层子页面的URL。接着，页面预读单元430继续根据下一层子页面的URL从网络资源服务器预读下一层子页面，然后由预读关键字分析单元420继续针对下一层子页面进行分析，直至预读规定层数的所有子页面。
考虑到用户的浏览习惯和大多数移动终端的终端配置，组合的子页数一般不超过四层，优选地对2～3层的子页进行合并重排。
为了使预读页面更加符合用户的浏览意向，在本发明的一个优选实施方式中，还将海量用户行为纳入预读的考虑因素之中，即中转服务器400还包括海量用户行为统计单元470，用于根据海量用户的网页浏览行为统计用户访问每一页面的历史访问行为、访问频率以及跳转访问率。海量用户行为统计单元470记录所有用户的访问行为，并基于这些行为的记录得出各种统计参数，如访问频率（即一天访问多少次）、某页面跳转到另外一个页面的几率等，这些都是基于用户的访问行为记录统计出来的。
此外，所述中转服务器400还可以包括确定单元（未示出），用于在所述URL地址获取模块从所述网络资源服务器获取要预读的子页面的URL地址之后，确定所述获取的URL地址与根据所述海量用户行为统计单元统计470得到的在访问所述页面之后最常访问的页面URL是否相同。如果相同，则所述页面预读单元430中的页面数据获取模块433根据所述已经预读的上一页面或上一子页面的下一子页面的URL，从所述网络资源服务器获取所述要预读的子页面的页面数据。如果不相同，则所述页面预读单元根据所述最常访问的页面URL的跳转访问率进行预读操作。其中，如果跳转访问率超过预设阈值，则所述页面预读单元430将最常访问的页面URL确定为从网络资源服务器获取的子页面的URL，从而从该URL获取页面数据；否则，如果所述跳转访问率没有超过预设阈值，则所述页面预定单元430不执行任何预读操作。
跳转访问率的预设阈值可根据经验值设定，如60%～80%之间的数值在本发明的一个优选实施方式中，预设阈值为70%，即如果这个网页的跳转访问率达到70%，就对最常被访问的网页进行预读，如果这个网页的跳转访问率没有达到70%，则不进行任何后续预读。
再一方面，本发明还提供一种包括移动终端、网络资源服务器和前述中转服务器的网页页面预读***，其方框图如图6所示。
这里要说明的是，上述实施例仅仅是例示性的，而不是限制性。本领域技术人员要明白的是，还可以对上述实施例进行各种修改。
例如，在一个示例中，图1中的合并和重排过程可以省略。同样，图4中的预读页面组合单元450以及海量用户行为统计单元470也可以省略。
此外，在根据所述获得的预读关键字中的具有最高优先级的预读关键字，从所述网络资源服务器预读该当前页面或子页面的下一子页面的页面数据，除了上述实施例中公开的方式之外，也可以采用本领域的其它公知方式。
本发明结合关键字的优先级、海量用户行为分析，对预读的页面进行契合用户浏览意向的选择，并对多个预读的页面进行合并重排版，不能使终端用户能够在不需要多次翻页的前提下一次性浏览到更多的网页内容，还从预读内容上使用户的浏览满意度得大大改善，从而更有效地提升了用户的网页浏览体验。
此外，根据本发明的方法还可以被实现为由CPU执行的计算机程序。在该计算机程序被CPU执行时，执行本发明的方法中限定的上述功能。
此外，上述方法步骤以及***单元也可以利用控制器或处理器以及用于存储使得控制器或处理器实现上述步骤或单元功能的计算机程序的计算机可读存储设备实现。
此外，应该明白的是，本文所述的计算机可读存储设备（例如，存储器）可以是易失性存储器或非易失性存储器，或者可以包括易失性存储器和非易失性存储器两者。作为例子而非限制性的，非易失性存储器可以包括只读存储器（ROM）、可编程ROM（PROM）、电可编程ROM（EPROM）、电可擦写可编程ROM（EEPROM）或快闪存储器。易失性存储器可以包括随机存取存储器（RAM），该RAM可以充当外部高速缓存存储器。作为例子而非限制性的，RAM可以以多种形式获得，比如同步RAM（DRAM）、动态RAM（DRAM）、同步DRAM（SDRAM）、双数据速率SDRAM（DDR SDRAM）、增强SDRAM（ESDRAM）、同步链路DRAM（SLDRAM）以及直接Rambus RAM（DRRAM）。所公开的方面的存储设备意在包括但不限于这些和其它合适类型的存储器。
本领域技术人员还将明白的是，结合这里的公开所描述的各种示例性逻辑块、模块、电路和算法步骤可以被实现为电子硬件、计算机软件或两者的组合。为了清楚地说明硬件和软件的这种可互换性，已经就各种示意性组件、方块、模块、电路和步骤的功能对其进行了一般性的描述。这种功能是被实现为软件还是被实现为硬件取决于具体应用以及施加给整个***的设计约束。本领域技术人员可以针对每种具体应用以各种方式来实现所述的功能，但是这种实现决定不应被解释为导致脱离本发明的范围。
结合这里的公开所描述的各种示例性逻辑块、模块和电路可以利用被设计成用于执行这里所述功能的下列部件来实现或执行：通用处理器、数字信号处理器（DSP）、专用集成电路（ASIC）、现场可编程门阵列（FPGA）或其它可编程逻辑器件、分立门或晶体管逻辑、分立的硬件组件或者这些部件的任何组合。通用处理器可以是微处理器，但是可替换地，处理器可以是任何传统处理器、控制器、微控制器或状态机。处理器也可以被实现为计算设备的组合，例如，DSP和微处理器的组合、多个微处理器、一个或多个微处理器结合DSP核、或任何其它这种配置。
结合这里的公开所描述的方法或算法的步骤可以直接包含在硬件中、由处理器执行的软件模块中或这两者的组合中。软件模块可以驻留在RAM存储器、快闪存储器、ROM存储器、EPROM存储器、EEPROM存储器、寄存器、硬盘、可移动盘、CD-ROM、或本领域已知的任何其它形式的存储介质中。示例性的存储介质被耦合到处理器，使得处理器能够从该存储介质中读取信息或向该存储介质写入信息。在一个替换方案中，所述存储介质可以与处理器集成在一起。处理器和存储介质可以驻留在ASIC中。ASIC可以驻留在用户终端中。在一个替换方案中，处理器和存储介质可以作为分立组件驻留在用户终端中。
