Description

一种信息交互的方法、设备和服务器以及系统

技术领域
本申请涉及通信技术领域，尤其涉及一种信息交互的方法、设备和服务器以及系统。
背景技术
传统的频谱资源主要通过授权方式以及免授权方式进行分配。一般来说，授权方式通过监管机构向主用户颁发牌照获得某一频谱资源的排他使用权，主用户也需要保证服务质量。免授权方式则不需要颁发特定的牌照，对接入的用户或运营商不做限制，通过尽力而为的方式提供服务并且没有服务质量的要求。
随着各类无线通信技术的不断发展，找到没有使用的新频谱已经变得越来越困难。对于已经规划的一些频段，由于短期内无法完成对其它无线通信业务的清频工作，应用排他式的授权接入方式面临极大的困难。因此，为了提供更多的可接入频谱，频谱共享接入方式已经开展了广泛的研究。频谱共享接入方式是指通过预先定义的协作条件实现和主用户的频谱共享，比如当主用户在特定区域或特定时间没有使用频谱时，允许其它业务共享接入该频谱。
在基于LBT的LTE系统(LAA和MF)和传统TDD-LTE系统共存的通信环境下，还未引入频谱共享的接入机制，因此，亟需一种可行的方案实现频谱共享。

具体实施方式
为了更好的理解本申请的技术方案，下面结合附图对本申请实施例进行详细描述。
应当明确，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
在本申请实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本申请。在本申请实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。
应当理解，本文中使用的术语“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
本申请实施例提供了一种信息交互的方法，用于解决基于LBT的LTE系统与传统TDD-LTE系统之间的频谱共享资源交互问题，以实现频谱资源的共享协商。该方法涉及基于LBT的LTE系统内的设备(例如，CBSD(citizen broadband radio service device，公民带宽无线服务设备)或者其代理设备)以及SAS(Spectrum Access System，频谱接入系统)服务器之间的交互。其中，SAS用于管理和分配至少包括基于LBT的LTE系统和传统TDD-LTE系统在内的各类LTE系统的共享频谱资源。该方法通过基于LBT的LTE系统内的设 备与SAS服务器进行交互，以实现SAS对基于LBT的LTE系统可使用的共享频谱资源的分配。在该方法中，该共享频谱资源至少包括基于LBT的LTE系统与TDD—LTE系统之间存在的共享频谱资源。总体流程如图1所示，包括：
101、设备向服务器发送第一指定信令消息，所述指定信令消息中携带有先听后说LBT相关信息。
102、服务器向设备返回第二指定信令消息对应的响应消息，所述响应消息中携带有LBT能量检测门限信息。
本申请实施例提供的信息交互方法，通过将有关基于LBT实现频谱共享所需的相关信息携带在指定信令在设备与服务器之间进行交互，以实现服务器对设备频谱接入能力的认知以及对可行LBT能量检测门限的选择，这样设备就可以基于服务器给出的LBT能量检测门限以及相应的已有接入机制完成频谱共享。因此，该方法弥补了在基于LBT的LTE系统(LAA和MF)和传统TDD-LTE系统共存的通信环境下，还未引入频谱共享的接入机制的缺失。
进一步需要说明的是，上述第一指定信令消息和第二指定信令消息可以是同一信令消息，也可以是不同的。
若第一指定信令消息和第二指定信令消息是相同的，则在本申请实施例中可以理解为完成一次频谱共享分配所需的LBT信息均在同一阶段的通信流程内完成，此处提到的通信流程可以为注册流程、频谱获取流程、授权流程以及心跳交互流程中的一个。
此时，第一指定信令消息和第二指定信令消息可均为包括注册请求消息、频谱获取请求消息、授权请求消息以及心跳消息这四种消息在内的各类请求消息中的一种。
若第一指定信令消息和第二指定信令消息是不同的，则在本申请实施例中可以理解为完成一次频谱共享分配所需的LBT信息至少需要在两个阶段以上的通信流程内才能交互完成。此处提到的两个阶段以上的通信流程可以包括注册流程、频谱获取流程、授权流程以及心跳交互流程中的两个或更多。
此时，第一指定信令消息和第二指定信令消息可以为包括注册请求消息、频谱获取请求消息、授权请求消息以及心跳消息这四种消息在内的各类请求消息中的任意两个或更多。

另外，本申请实施例在第一指定信令消息和第二指定信令消息不同的前提下，针对指定信令消息及其响应信息的实现，提供了以下几种可行的实现方式。下文中与前述描述内容相同的部分可参照前述描述，本申请实施例不再赘述。
第一种实现方式，如图6所示，该方式以注册流程和频谱获取流程为基础实现，具体如下：
601、所述设备通过注册请求消息发送指定信令消息，该注册请求消息携带有LBT相关信息。
602、所述服务器通过注册请求消息对应的注册响应消息向设备 返回所述指定信令消息对应的响应消息。该注册响应消息可以不携带任何与LBT相关的信息。
603、所述设备通过频谱获取请求消息发送指定信令消息，该频谱获取请求消息可以不携带任何与LBT相关的信息。
604、所述服务器通过频谱获取请求消息对应的频谱获取请求响应消息向设备返回所述指定信令消息对应的响应消息，该响应消息中携带有LBT能量检测门限信息。
以上步骤601至604描述了结合两个阶段的通信流程完成LBT信息交互的方案，在该方案中，涉及上报流程的步骤有601和603，而涉及下达流程的步骤有602和604。本方案仅在前一次上报步骤601和后一次下达步骤604交互与LBT有关的信息。
因此，其实现原理可以理解为在前一次通信流程的上报步骤完成LBT相关信息的上报，在后一次通信流程的下达步骤完成LBT检测能量门限信息的下达。
当然此处提及的注册流程和频谱获取流程仅是示例，任何时间上具有先后次序的通信流程都可以适用于上述方案所表达的实现原理。例如，注册流程和授权流程、注册流程和心跳交互流程、授权流程和心跳交互流程等等的流程组合都可以适用于本申请实施例。
并且，本申请实施例并不要求两个通信流程在时间上是连续的，因此在完成前一次通信流程后，即完成前述步骤601和602后，还可以执行其它与LBT交互不相关的通信流程，之后在启动频谱获取流程时再继续完成后一次通信流程，即执行前述步骤603和604。
在此补充说明的是，前述方案仅依靠两个通信流程完成LBT信息交互，在本申请实施例中也可以依靠多个通信流程的上报流程分多次完成前述LBT相关信息的上报，也可以依靠多个通信流程的下达流程分多次完成LBT能量检测门限信息的下达。
第二种实现方式，如图7所示，该方式以注册流程和频谱获取流程为基础实现，具体如下：
701、所述设备通过注册请求消息发送指定信令消息，该注册请 求消息携带有LBT相关信息。
702、所述服务器通过注册请求消息对应的注册响应消息向设备返回所述指定信令消息对应的响应消息，该响应消息中携带有LBT能量检测门限信息。
703、所述设备通过频谱获取请求消息发送指定信令消息，该频谱获取请求消息中携带有LBT相关信息。
704、所述服务器通过频谱获取请求消息对应的频谱获取请求响应消息向设备返回所述指定信令消息对应的响应消息，该响应消息中携带有LBT能量检测门限信息。
在该第二种实现方式中，步骤701、703上报的LBT相关信息一般不相同，在各步骤上报的LBT相关信息不同的前提下，步骤702、704下达的LBT能量检测门限信息一般也是不相同的。
与前述第一种实现方式不同，该第二种实现方式会存在多次交互的情况，在该第二种实现方式中并不要求在同一通信流程或两个通信流程内就完成LBT信息的交互，而是允许存在多次交互的情况。而且，每个通信流程中所涉及的LBT信息的交互可以预先配置其传输内容类型或传输信息格式等内容，或者，根据实际情况动态调整。
需要补充说明的是，与前述第一种实现方式类似，此处提及的注册流程和频谱获取流程仅是示例，任何时间上具有先后次序的多个通信流程都可以适用于上述方案所表达的实现原理。例如，注册流程和授权流程、注册流程和心跳交互流程、授权流程和心跳交互流程等等的两两流程的组合，或者可能存在的更多数量流程的组合都可以适用于本申请实施例。
以上两种实现方式均允许完成一次频谱共享分配所需的LBT信息在多个通信流程中完成传输。
进一步来说，为了能够降低传统TDD-LTE系统和基于LBT的LTE系统之间的干扰，本申请实施例在前述步骤的基础上还提供了以下调整流程，具体如图6所示，还包括：
103、所述服务器根据所述服务器所在的目标接入系统的发送功 率、带外辐射以及目标接入系统与待接入系统之间的地理位置信息，调整所述目标接入系统的发送功率、两系统之间的隔离带宽以及待接入系统的LBT能量检测门限三者中的至少一个。
其中，目标接入系统在本申请实施例中可以为传统的TDD-LTE系统，相应的待接入系统可以为基于LBT的LTE系统。有关目标接入系统和待接入系统的配置和选择可以根据实际情况预先设定，或者由SAS服务器进行配置。
补充说明的是，该调整流程中可以执行在频谱共享过程中的任意时机，具体时机的设置可以根据实际需要进行配置。
基于CBSD系统的带外辐射要求，在此举例说明本申请实施例所提供的调整LBT能量检测门限的方法。
CBSD系统的带外辐射要求为在占用信道的边界之外0-10MHz的带外辐射低于-13dBm/MHz，10MHz以外的带外辐射低于-25dBm/MHz,在可用频带之外，低于3530MHz或者高于3720MHz的带外辐射低于-40dBm/MHz。
假设两系统距离较近，隔离度MCL(Maximum Coupling Loss)为50dB,当隔离带宽为0MHz的情况下，目标接入系统辐射到待接入系统的信号强度为-13dBm/MHz–50dB＝-63dBm/MHz,需要设置待接入系统的LBT能量检测门限高于-63dBm/MHz,这样待接入系统的LBT才可能成功。当隔离带宽为10MHz及以上的情况下，目标接入系统辐射到待接入系统的信号强度为-25dBm/MHz–50dB＝-75dBm/MHz,需要设置待接入系统的LBT能量检测门限高于-75dBm/MHz,这样待接入系统的LBT才可能成功。假设两系统距离较远，隔离度MCL(Maximum Coupling Loss)为100dB,当隔离带宽为0MHz的情况下，目标接入系统辐射到待接入系统的信号强度为-13dBm/MHz–100dB＝-113dBm/MHz,需要设置待接入系统的LBT能量检测门限高于-113dBm/MHz。
有关所述目标接入系统的发送功率、两系统之间的隔离带宽的调整方法也可以参照上述对LBT能量检测门限的调整方法，可根据 实际需要进行设计。
另外，除了目标接入系统的发送功率、带外辐射以及目标接入系统与待接入系统之间的地理位置信息外，所述服务器还可以根据待接入系统中不同牌照的接入优先级，为不同牌照的系统配置相应的LBT能量检测门限。例如给高优先级牌照(如PAL)的系统配置较高的LBT能量检测门限，给低优先级牌照(GAA)的系统配置较低的LBT能量检测门限。简化情况下可以只设置LBT开启或LBT关闭两者制式。
另外，当待接入系统的设备即支持TDD-LTE协议也支持基于LBT的LTE协议时，除了目标接入系统的发送功率、带外辐射以及目标接入系统与待接入系统之间的地理位置信息外，所述服务器还可以根据待接入系统可能受到的干扰情况，为待接入系统的设备配置协议标准。例如，当受到TDD-LTE系统较大的干扰时，将待接入系统的设备配置为TDD-LTE系统，具体的子帧配置，特殊子帧配比以及同步信号都与干扰源的TDD-LTE系统相同。当受到TDD-LTE系统较小的干扰时，将待接入系统的设备配置为基于LBT的LTE系统。
进一步来说，当所述服务器检测到新的待接入系统时，修改所述服务器所在的目标接入系统的共享频谱使用范围和/或最大发送功率和/或LBT能量检测门限和/或协议标准。
