Description

一种热扩容POI设备以及方法 技术领域
本发明涉及POI(POINT OF INTERFACE，多系统合路平台)设计领域，尤其涉及一种热扩容POI的设备以及方法。
背景技术
POI(多系统接入平台或多系统合路平台)作为一种通信设备，在国内已经有了15年以上的历史，POI的出现是共建共享理念的结果，POI因为是多系统接入，基本的主要指标有接入频段、插损、驻波、隔离、功率和互调等，频段是衡量POI接入能力的指标，所以一旦接入频段或者制式发生变化，原POI将不能使用，必须研制生产新的设备，POI是多系统合路设备，抗干扰能力是核心指标，隔离和互调是抗干扰能力的具现，同样任何一个指标的变化也会导致原设备不能使用。
移动通信技术的更迭迅速，原有的业务和频段随着技术的进步逐步的不能适应，技术每一年都在改变中，而无源系统设备20万小时的寿命远远超过了技术更新期，所以老设备的继续服役是每个建设方的诉求，是业界发展到今天的难题，热扩容成了很多运营商和建设方的现实需求，尤其是长时间的脱网会严重影响用户感知，影响品牌知名度。所谓的热扩容：指不中断覆盖的情况下实现扩容、改造或升级。
现有技术中，即使有POI的设计，已不能满足目前更多系统、更多制式、差异化扩容的场景，不能保证全业务的接入能力；且由于其单个抽屉承载的业务较多，改造升级等工作量较大。
综上描述，传统的POI不能很好的解决热扩容的问题。
发明内容
本发明的目的是提供一种热扩容POI设备。
本发明的另一目的是提供一种采用热扩容POI设备的方法。
为了实现上述目的，本发明提供以下技术方案：
本发明涉及的一种热扩容POI设备，用于更换不同频段的接入，其包括扩展模块和基础模块，所述扩展模块，用于对接入信号进行分类且各分类信号形成相互独立的通路，然后再对所述各通路进行整合；所述基础模块，用于所述扩展模块经过分类并整合的信号进行合路，然后再混频输出。
进一步，所述对接入信号进行分类，是指依照所述基础模块的支持通信频段信号类别对接入信号进行分类。
进一步，所述对各属于同一支持通信频段信号进行整合，是指对属于同一个支持的通信频段且独立、零散的频段进行整合。
进一步，所述扩展模块包括用于不同支持通信频段的扩展子模块。
进一步，所述扩展子模块包括对应接入同一业务信号的滤波器。
进一步，所述扩展子模块包括对应接入不同业务信号合路的合路器。相比现有技术，本发明的方案具有以下优点：
与传统的POI设备，其利用了其中基础模块对每个输入端口都对应输入各自的支持通信频段的特性，在接入基础模块1之前，对应基础模块1的每个输入端加装先对其相应业务信号滤波或合路的扩展子模块。当接入新业务信号时，只需更换或调整新业务信号相应的扩展子模块内的分类结构，以免信号传输因脱网时长而影响用户使用。
本发明涉及的采用上述热扩容POI设备的方法，包括以下步骤：对接入信号进行分类且各分类信号形成相互独立的通路；对所述各通路信号进行整合，并输出各相互独立的整合信号；对各整合信号进行合路，并混频输出。进一步，所述对接入信号进行分类，是指依照所述基础模块的支持通信频段信号类别对接入信号进行分类。
进一步，所述对各属于同一支持通信频段信号进行整合，是指对属于同一个支持的通信频段的独立、零散的频段进行整合。
进一步，所述形成相互独立的通路，是指对接入信号进行分类后进行独立传输。
进一步，当需要更换接入新业务信号时，暂停传输其相应接入的通路； 接入新业务信号后，对新业务信号进行滤波。
进一步，当需要接入新业务信号时，暂停传输其相应接入的通路；接入新业务信号后，对新增业务信号和原业务信号进行合路。
相比现有技术，本发明的方案具有以下优点：对原POI设备直接对接入信号合路再混频输出的传统方式前，先分类在整合的方式，使接入信号可分，当不同分类信号许接入新业务信号时，只需暂停新业务信号所对应接入端的信号传输，不影响其他接入端的信号传输，以免因脱网而影响用户体现。
本发明附加的方面和优点将在下面的描述中部分给出，这些将从下面的描述中变得明显，或通过本发明的实践了解到。
附图说明
本发明上述的和/或附加的方面和优点从下面结合附图对实施例的描述中将变得明显和容易理解，其中：
图1为本发明提供的热扩容POI设备的实物图；
图2为本发明提供的热扩容POI设备的电路原理图。
具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本发明，而不能解释为对本发明的限制。
如图1所述的热扩容设备，其包括基础模块1和扩展模块2，用于对接入移动通信信号以及向天馈分布系统输出信号。扩展模块2形成各相互独立的通路向所述基础模块1进行传输。具体地，扩展模块2包括若干个扩展子模块，扩展子模块间形成相互独立的通路对基础模块1进行信号传输，且可以更换其中的某个或者若干个扩展子模块而不影响其他扩展子模块的运作。当需要业务升级时，只需更换接入新业务信号的所对应扩展子模块，其它扩展子模块业务正常运行，无需改变或者停止运行。而基础模 块1能够提供从DC到2.7GHz的接入能力(DC指频率低至0Hz的信号，通信行业通常用DC表示)，涵盖了主要移动通信接入的业务频段，是扩展、升级和改造的基础，通过扩展子模块提供了具体业务的接入，改变扩展子模块可改变的相应接入业务。扩展模块2的灵活性结合基础模块1的强大接入能力保证了扩容升级业务的顺利接入。
所述扩展模块2的每个扩展子模块提供相互独立的通路，在频段整合、载波聚合、升级换代时，在对应的扩展子模块上即可实施。
所述热扩容POI设备接入的信号来自不同的运营商，其频段不同，基础模块1对接入信号的支持通信频段类别进行分类接入，如表1所示，基础模块1的每个输入端口都对应输入同一支持通信频段，因此，基础模块1的每个输入端口对应接入的各个扩展子模块需依照支持通信频段的划分，对接入信号设定不同的支持通信频段范围，以作调试或更换相应的扩展子模块的依据。
所述热扩容POI设备，基础模块1可提供接入制式和频段如表1。
Figure PCTCN2017119549-appb-000001
基于不同的支持通信频段对应有相应的频段和不同的制式，使得每个扩展子模块对接入信号分类再将各自属于同一个支持的通信频段且独立、零散的频段(甚至是不同制式的接入信号)整合到一起，进行载波聚合。同时，载波聚合对独立、零散的频段需等于高于5MHz，最佳情况的是大 于10MHz。
因此，载波聚合时涉及到同一支持的通信频段的零散频段先进行整合，形成一个联通的大于5MHz的频段，再和属于同一支持通信频段的其它承载的业务信号的频段进行载波聚合。在本实施例中，本扩展模块分为4组，每组有4个扩展子模块，共有4*4个扩展子模块(201-216)，如图2所示，每个扩展子模块间为相互独立的通路。当上述载波聚合的情况发生，以接入其中第一扩展子模块201为例，此时其接入能力发生了变化，新业务接入，需要对扩展子模块201调试或者更换相应的传输机构，使之支持新要求。具体如下：
当需要将原业务信号更换为新的业务信号接入时，暂停新业务信号所对应接入的扩展子模块的信号传输，将该扩展子模块由原业务信号对应的滤波器更换为新业务信号对应的滤波器。在一实施例中，第一扩展模块201原业务信号为GSM900，因业务升级需更换为LTE700的业务信号，此时，第一扩展子模块201抽出，，如图1所示，将其内部的GSM滤波器更换为LTE滤波器。
当需要增加新的业务信号接入时，暂停新业务信号所对应接入的扩展子模块的信号传输，将该扩展子模块更换为对新业务信号与该扩展子模块对应接入的原业务信号进行合路的合路器，所述原业务信号和新业务信号属于同一支持通信频段。在另一实施例中，第一扩展模块201原来的接入信号为GSM900的业务信号，因业务升级需增加LTE700的业务信号，此时，第一扩展子模块201抽出，如图1所示，将其内部的GSM滤波器更换为可接入700MHz和900MHz对应的合路器。
在上述的两种更换第一扩展子模块201相应传输机构的过程中，第二至第十六扩展子模块(202-216)依然正常运行，不受第一扩展子模块201内部变动的影响。
基础模块1由4个合路器102组成，每个合路器102可提供如表1的4个支持通信频段接入，即基础模块1可提供4*4的支持通信频段接入，相同的支持通信频段在该基础模块1的4个合路器中可接入最多4组。电桥101是集成耦合器103的4进4出电桥，该部分也可如图2表示的4个 电桥组成，提供4进4出的分合路功能，作用是将16路信号混频后引入天馈分布系统，同时将接受到的天馈信号反馈回信源。
本发明提供一种采用上述热扩容POI设备的方法，其对该技术方案的贡献是当需要接入新业务信号时，新业务信号对应接入通路暂停传输，当接入新业务信号后，就可恢复对应接入通路的传输。这样，无需停止所有接入通路的传输，待接入新业务信号后才能恢复全部传输。
该方法的方案是先对接入信号分类，各类别的信号为独立的通路，互不干扰，且可以更换其中某一个或若干个的通路而不影响其他通路的运作。然后再对分类后的信号进行整合，形成各相互独立的整合信号，最后分别各整合信号进行合路、混频输出至天馈分布系统，该技术方案的技术效果是即使接入信号增加新业务信号，也不会影响其他业务信号的传输。
该方案的具体方案是依照基础模块1的支持通信频段类别，在接入基础模块1之前先对接入信号分成不同支持通信频段的传输通路，相互间独立传输，互不干扰。然后，再对分类后的属于同一支持通信频段的信号进行整合。该根据表1可知，即使同一支持通信频段的信号也包括来自相应的频段以及不同的业务制式，即可能来自不同的运营商或者公共机构，因此，属于同一支持通信频段包括独立且零散的频段，在基础模块1合路前，要对这些同一支持通信频段的独立且零散的频段进行整合，进行载波聚合。然后再向通过基础模块1进行合路和混频输出。其中，载波聚合对独立、零散的频段需等于高于5MHz，最佳情况的是大于10MHz。
因此，载波聚合时涉及到同一支持的通信频段的零散频段先进行整合，形成一个联通的大于5MHz的频段，再和属于同一支持的通信频段的其它承载业务的频段进行载波聚合。根据上述的热扩容POI设备，当接入新业务信号时，适应地调试或更换为对新业务信号的传输，具体地如下:
当需要将原业务信号更换为新业务信号接入时，暂停新业务信号所接入的通路的传输。接入新业务信号后，由原来对原业务信号进行滤波更换为对新业务信号进行滤波。在一实施例中，原业务信号为GSM900，因业务升级需更换为LTE700的业务信号，此时，将业务信号的接入方式为对LTE700的滤波处理，再进行传输。
当需要增加新的业务信号接入时，暂停新业务信号所接入的通路的传输，。接入新业务信号后，将新增加的业务信号与该通路原业务信号进行合路传输，所述原业务信号和新业务信号属于同一支持通信频段。在一实施例中，原业务信号为GSM900，因业务升级需增加LTE700的业务信号，此时，将对这两路业务信号进行合路传输。
在上述的两种调整新业务信号所接入通路的过程中，其他通路的运作不受影响。
经过对接入信号分类、整合以及分频段的独立传输后，基础模块1需要对所述不同的相互独立的通路进行合路和混频后，最后向天馈分布系统输出。基础模块1对不同通路进行对应分组接入并且合路，形成多路合路信号后，再经过混频后在想天馈分布系统输出，同时将接受到的天馈信号反馈回信源。在本实施例中，与扩展模块2对应，基础模块1中有4个合路电路，每个合路电路有4个合路输入，即基础模块1可提供4*4的支持通信频段接入。
本发明提供的一种热扩容POI设备以及方法，其是利用基础模块1的每个输入端口相互间输入不同的支持通信频段的特性，在接入基础模块1之前，先对各业务信号滤波或合路来分类，使分类后的信号形成相互独立的各个通路传输，达到其中的某个或若干个通路暂停传输而不影响其他通路传输的技术效果。这样，在需要接入新业务信号时，只需暂停新业务信号所接入通路的信号传输，无需停止所有通路的传输，以避免因长时间的脱网会严重影响用户使用。
以上所述仅是本发明的部分实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
