Description

彩铃的播放方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种彩铃的播放方法及装置。
背景技术
随着电信增值业务的推广应用，彩铃系统由于彩铃的购买和使用方便，也被广泛使用。彩铃的试听功能是订购业务流程中不可或缺的部分，给用户提供一个操作简单、友好的用户体验，越来越被很多厂商重视，一方面可以提高业务的服务质量，另一方面可以吸引更多的新用户关注，作为新一代的客户端互联网技术的佼佼者，Adobe公司的Flex这种技术已经被越来越多的公司所采用，被越来越多的用户所接受，据官方API约定(swf_file_format_spec_v10.pdf，第201页)Flex的API采样率仅支持5.5kHz、11kHz、22kHz和44kHz，其中5.5kHz对mp3播放文件不支持，对wav格式的音频文件不支持。而彩铃的文件格式为wav，采样率为8kHz，因此如果要播放彩铃这种格式的文件，显然相关技术是不支持的；尽管可以使用PopForge开源类库能够对Flex很好的扩展，但是对于8kHz的采样率的wav文件播放，采用该方式容易造成失真现象导致播放音质很不理想，可见相关技术中虽然可以缓解失真问题，但是音质不容乐观，依然存在很多弊端，图1是相关技术中彩铃播放过程的示意图，如图1所示，Web服务用于彩铃系统的运行容器，并提供给彩铃系统运行环境，控制铃音订购、播放，列表展示等；流媒体服务用于以流的方式在网络中传输音频、视频和多媒体文件，铃音文件的转换存储；铃音播放模块用于根据铃音文件的URL播放铃音的应用；
其中，彩铃播放过程是由Web服务向流媒体服务定时发出音频文件转换操作请求任务，流媒体服务根据发出的定时任务，将音频文件的格式wav转换为mp3格式，将音频文件的采样率8kHz转换为44kHz，将结果存储在流媒体服务器的硬盘上，Web服务收到HTTP/HTTPS请求播放某铃音的URL后，将请求的铃音参数信息发给流媒体服务会根据参数信息查询转换后的铃音数据，将结果返回给Web服务收到转换后的结果信息后重新封装URL请求，将铃音文件加载到铃音播放模块将铃音信息输出给用户。
采用相关技术中上述方案将会产生如下问题：
1.流媒体服务收到要播放的铃音请求后，而定时任务未完成导致此音频文件转换或转换失败，进而造成转换完后的文件有轻微杂音；
2.流媒体服务转换后的文件占用硬盘空间会很大，需要额外考虑存储空间， 消耗资源和经济成本；
3.流媒体服务新增加的音频文件不能立刻给用户试听和订购，需要等任务执行完后才能使用，一般是需要等到第二天，影响用户体验；
针对相关技术中彩铃音频文件的播放不能立刻给用户试听或订购的问题，目前尚未提出有效的解决方案。

图7是根据本发明可选实施例的基于FLEX铃音播放模块的彩铃播放方法流程图，如图7所示，该方法包括：
步骤S702：将区域内的同类型小小区编号；每个小小区各自为一簇；收集两两小小区间的RSRP较大值；将RSRP列表Q从大到小排序，低于门限值L的RSRP值不予统计入列表；
步骤S704：判断Q集合是否为空集；在Q集为空时，执行步骤S706；在Q集不为空时，执行步骤S708；
步骤S706：分簇完毕；
步骤S708：判断列表中RSRP最大值相对应的两个小小区所在的簇合并后是否超过簇内的小小区个数门限T；判断结果为否时，执行步骤S712，在判断结果为是时，执行步骤S710；
步骤S710：两簇不作调整且该行从列表Q中剔除；
步骤S712：两簇合并，两小小区端点间添加边，且该行从列表Q中剔除。
在图7的基础上结合图8进行相应的说明，图8是根据本发明可选实施例的彩铃播放过程示意图，如图8所示，FLEX铃音播放模块负责彩铃系统中铃音文件的播放，首先是需要动态构建一个wsf(shock wave flash)文件,将获取到的HTTP/HTTPS请求的资源以字节形式加载到wsf文件中，判断读取音频文件字节流数据是否成功，如果成功将数据从音频流压入数据栈中，否则将错误信息返回并记录错误信息日志，然后从数据栈中获取到音频头信息，采用G.711(mu-law)解码，判断被解码的音频数据采样频率是否正确，即判断采样率是否是44kHz，如果不是44kHz需要将采样频率转换为44kHz，然后继续判断采样率采样是否成功，如果失败，则将返回播放失败信息并将结果保留到信息日志，如果成功则输出成44100频率的解码流输出到wav格式文件中，将此wav格式文件内嵌到构造的swf文件中，最后通过类调用资源库的方式，播放此swf内部的wav文件。
本可选实施例中由铃音播放模块完成音频格式转换，采用实时播放和实时转换，将异常处理信息保存起来，便于维护运营商检查铃音文件的正确性，此外在确保了系统可用性的同时，提高了系统处理的实时性和准确性。
上仅为本发明的可选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
工业实用性
通过本发明实施例，采用在获取到待播放彩铃的音频信息之后，判断该音频信息的采样频率是否为预设频率，如果不是则将该音频信息的采样频率转换为预设频率，并将播放采样频率为预设频率的彩铃的方式，此过程中，执行上述步骤的主体可以是Flex铃音播放模块，该Flex铃音播放模块在播放彩铃的过程中并不需要先转换音频文件的格式，只需要转换音频文件的采样频率，当然如果音频文件为预设采样频率时，则不需要转换，当音频文件为预设文件之后直接可以播放该音频文件，解决了相关技术中彩铃音频文件的播放不能立刻给用户试听或订购的问题，提高了用户体验。
