Description

通信方法、装置及计算机可读存储介质 技术领域
本公开涉及通信技术领域，尤其涉及一种通信方法、装置及计算机可读存储介质。
背景技术
随着通信技术的发展，通信使用的频率资源向着高频方向发展。在5G和5G之前的通信系统中，频率资源预先配置给接入网设备，由接入网设备进行集中式调度。而在5G以后的通信系统中，频率资源将发展到毫米波频段和太赫兹频段。在使用毫米波频段和太赫兹频段进行通信的通信系统中，能够使用的频段很宽，而接入网设备覆盖范围较小，也即是，一个接入网设备覆盖范围内的终端数量相对较少，若仍然延用5G以及5G之前的通信系统中的频率资源的分配方式，将使得通信效率较低。

可选地，该步骤403可以在第一接入点设备开机时执行或者在第一接入点 设备开启接入点功能时执行。第一接入点设备在开机时，需要先获取频率使用记录信息，并根据频率使用记录信息，从可用频段资源中确定出空闲频率资源，然后从空闲频率资源中选择自身所要使用的频率资源，即工作频率。
在步骤404中，第一接入点设备根据所述第一频率使用记录信息，从可用频段中确定第一频率。
该第一频率属于所述可用频段中未包含在所述第一频率使用记录信息中的频率。
示例性地，第一接入点设备可以根据自身的带宽能力，从剩余频率中确定出与自身带宽能力相匹配的第一频率，也即是，第一频率的频域宽度不超过第一接入点设备支持的带宽。
可替代地，第一接入点设备可以根据运营商授权使用的授权带宽，从剩余频率中确定出与授权带宽相匹配的第一频率，也即是，第一频率的频域宽度不超过第一接入点设备支持的带宽。

在步骤405中，第一接入点设备发送频率占用请求，所述频率占用请求包括第一频率的指示信息。
该频率占用请求用于表示第一接入点设备期望采用该第一频率作为第一接入点设备的工作频率，以便于在该工作频率上与终端进行通信。
示例性地，该第一频率的指示信息包括频率的起始位置和偏移量，该偏移量表示频率的结束位置相对于起始位置的偏移，基于该起始位置和偏移量，可以得到频率的结束位置。
可选地，该频率占用请求中还包括第一接入点设备的标识和时间戳。

在步骤408中，第一接入网设备接收其他接入网设备发送的频率占用请求。
其他接入网设备发送的频率占用请求，是通过其他接入网设备请求频率的其他接入点设备发送的。
在步骤409中，第一接入网设备根据第一接入网设备发送的频率占用请求和其他接入网设备发送的频率占用请求，生成第二频率使用记录信息。
通过该步骤407至409可以实现，该区域内的接入网设备同步频率占用请求，并基于相同的规则，生成第二频率使用记录信息。需要说明的是，若第一接入网设备的覆盖范围内不存在其他接入网设备，则无需执行该步骤407至409。
需要说明的是，接入网设备之间相互发送和接收信息可以通过有线接口或者空中接口实现，该空中接口与接入网设备向接入点设备和终端广播频率使用记录信息的接口不同。
该步骤409可以包括，第一接入网设备根据第一接入点设备发送的频率占用请求和其他接入网设备发送的频率占用请求，确定通过这多个接入网设备接入的接入点设备所请求的工作频率是否存在冲突(即是否存在相同的频率)，当不同接入点设备选择的工作频率之间存在冲突时，可以根据频率占用请求中的时间戳来确定究竟哪个接入点设备可以使用该工作频率，从而保证终端的工作频率不冲突。
示例性地，第一接入网设备可以将时间戳较早的频率占用请求对应的工作频率加入该第二频率使用记录信息中。
在步骤410中，第一接入网设备发送第二频率使用记录信息。
该步骤410可以参见步骤402，在此不再详细描述。
在步骤411中，第一接入点设备接收该第二频率使用记录信息。
在步骤412中，若所述第二频率使用记录信息中包括指示第一接入点设备占用第一频率的使用记录，则执行将第一频率作为工作频率。
若第二频率使用记录信息中不包括该指示第一接入点设备占用第一频率的使用记录，则将该第二频率使用记录信息作为新的第一频率使用记录信息，再次执行步骤404至步骤411，直至确定出工作频率。
这里，所述指示第一接入点设备占用第一频率的使用记录包括所述第一接 入点设备的标识和所述工作频率的标识。
在步骤413中，第一接入点设备在工作频率上发送第一信号。
可选地，该第一信号为导频信号。终端通过接收该导频信号，可以基于该导频信号接入第一接入点设备。
在步骤414中，终端接收该第一信号。
在步骤415中，终端根据该第一信号发送请求信息。

在建立通信连接之后，终端和第一接入点设备即可以在工作频率上进行通信。
可选地，该方法还可以包括：第一接入网设备发送第一频率释放通知，该第一频率释放通知用于指示第一接入点设备释放工作频率。
可选地，第一接入网设备可以广播该频率释放通知，使得通过第一接入网设备接入的接入点设备均能够接收到该第一频率释放通知；或者，第一接入网设备仅向通过第一接入网设备接入的接入点设备中的部分设备发送该第一频率释放通知。
相应地，该方法还可以包括：第一接入点设备接收所述第一接入网设备发送的频率释放通知，第一接入点设备根据该频率释放通知释放工作频率。

可选地，该方法还可以包括：第一接入点设备向第一接入网设备发送第二频率释放通知，所述第二频率释放通知用于告知所述接入网设备所述接入点设备即将释放工作频率。
可选地，第一接入点设备在关机和/或休眠之前，发送该第二频率释放通知。在第一接入点设备不需要使用工作频率的情况下，通过该第二频率释放通知告知第一接入网设备，使得第一接入网设备能够及时将第一接入点设备对应的工作频率纳入可用频段中未被占用的频率，例如将第一接入点设备的工作频率对应的频率使用记录从频率使用记录信息中删除，以便于后续供其他接入点设备使用，提高了频率资源的利用率。
相关技术中，由接入网设备采用集中式资源调度的方式，来控制接入点设 备的工作频率，而在本公开实施例中，接入点设备可以根据被占用频率来选择工作频率，接入网设备仅起到信息传递和信息传递的作用，在可用频段与太赫兹频段至少部分重合的情况下，可用频段的频域范围较宽，且该频段的信号的传输距离较短，能够在该频段工作的接入点设备的覆盖范围较小，所以可以通过分布式资源管理的方式来进行频率资源的调度，提高通信效率，并且简化接入点设备的工作流程。
图6是根据一示例性实施例示出的一种通信方法的流程图。与图5所示实施例的区别在于，图5所示实施例中，第一接入点设备需要从运营商建设的接入网设备获取频率使用记录信息，而在图6所示实施例中，第一接入点设备直接从其他接入点设备获取频率使用记录信息。
参见图6，该方法包括以下步骤：
在步骤501中，第一接入点设备获取第一频率使用记录信息。
关于第一频率使用记录信息的相关内容，可以参见步骤401，在此不再赘述。
可选地，该步骤501可以在第一接入点设备开机时执行，或者，在第一接入点设备开启接入点功能时执行。
可选地，第一接入点设备在设定的广播频率上接收频率使用记录信息。示例性地，设定的广播频率是一个固定频率，处于正常工作状态的第二接入点设备会在该广播频率上周期性地广播频率使用记录信息，以使得新开机的第一接入点设备能够及时获知当前的频率使用记录信息，并且使得各个第二接入点设备之间的频率使用记录信息能够保持同步。
在步骤502中，第一接入点设备根据所述第一频率使用记录信息，从可用频段中确定第一频率。
该第一频率属于所述可用频段中未被占用的频率。
示例性地，第一接入点设备可以根据自身的带宽能力，从剩余频率中确定出与自身带宽能力相匹配的第一频率，也即是，第一频率的频域宽度不超过第一接入点设备支持的带宽。
可替代地，第一接入点设备可以根据运营商授权使用的授权带宽，从剩余频率中确定出与授权带宽相匹配的第一频率，也即是，第一频率的频域宽度不超过第一接入点设备支持的带宽。
这里，剩余频率即为所述可用频段中未被占用的频率。当第一频率使用记 录信息用于指示可用频段中已被占用的频率时，剩余频率为所述可用频段中未包含在所述第一频率使用记录信息中的频率，也即是，可用频段中除了第一频率使用记录信息中包含的频率以外的频率。
在步骤503中，第一接入点设备发送频率占用请求。
第一接入点设备可以广播该频率占用请求。该频率占用请求包括第一频率的指示信息。该频率占用请求用于表示第一接入点设备期望使用该第一频率作为工作频率。
示例性地，第一频率的指示信息可以包括第一频率的起始位置和偏移量。该偏移量表示频率的结束位置相对于起始位置的偏移，基于该起始位置和偏移量，可以得到频率的结束位置。
在步骤504中，第一接入点设备获取第二频率使用记录信息，第二频率使用记录信息是根据所述频率占用请求得到的。
在该步骤504中，第一接入点设备在设定的广播频率上接收第二接入点设备广播的第二频率使用记录信息。第二接入点设备广播的第二频率使用记录信息，是第二接入点设备根据接收到的频率占用请求和第一频率使用记录信息生成的。
第二接入点设备生成第二频率使用记录信息的方式可以参见前述步骤409，在此省略详细描述。
在步骤505中，若所述第二频率使用记录信息中包括指示第一接入点设备占用第一频率的使用记录，则第一接入点设备将该第一频率确定为工作频率。
需要说明的是，若第二频率使用记录信息中不包括该指示第一接入点设备占用第一频率的使用记录，则第一接入点设备将该第二频率使用记录信息作为前述第一频率使用记录信息，再次执行步骤502至504，直至第一接入点设备确定出工作频率。
在步骤506中，第一接入点设备在将第一频率确定为工作频率之后，广播第二频率使用记录信息。
在步骤507中，第一接入点设备在确定出的工作频率上发送第一信号。
可选地，该第一信号为导频信号。终端通过接收该导频信号，可以基于该导频信号接入第一接入点设备。
在步骤508中，终端接收该第一信号。
在步骤509中，终端根据该第一信号发送请求信息。
在步骤510中，第一接入点设备响应于接收到的所述终端发送的请求信息，与所述终端建立通信连接。
在建立通信连接之后，终端和第一接入点设备即可以在工作频率上进行通信。
需要说明的是，若在第一接入点设备执行该步骤501之前，第一接入点设备的覆盖范围内不存在处于正常工作状态的其他接入点设备，则第一接入点设备将接收不到该第一频率使用记录信息。相应地，该方法还包括：若第一接入点设备在设定时长内未接收到第一频率使用记录信息，则直接从所述可用频率中确定第一接入点设备的工作频率。
在一种可能的实施方式中，由于太赫兹频段附近频段的频域范围较宽，频率资源充足，两个接入点设备同时开机且选择的工作频率相互冲突的可能性极低，所以第一接入点设备在设定时长内未接收到第一频率使用记录信息的情况下，可以直接将从可用频段中选择的频率作为工作频率，并在该工作频率上发送第一信号。
在另一种可能的实施方式中，第一接入点设备在设定时长内未接收到第一频率使用记录信息的情况下，可以发送频率占用请求(相关内容参见前述步骤503)；并接收其他接入点设备发送的频率占用请求。若在设定时长内未接收到其他接入点设备发送的频率占用请求时，将第一频率作为工作频率。若在设定时长内接收到其他接入点设备发送的频率占用请求时，按照设定的规则，确定第一接入点设备发送的频率占用请求是否能够生效。若第一接入点设备发送的频率占用请求能够生效，则将第一频率作为工作频率，若第一接入点设备发送的频率占用请求不能生效，则重新选择频率发送相应的频率占用请求。
示例性地，可以按照时间戳来确定生效的频率占用请求，例如，若该第一接入点设备发送的频率占用请求的时间戳早于其他接入点设备发送的频率占用请求的时间戳，则该频率占用请求能够生效。若该第一接入点设备发送的频率占用请求的时间戳晚于其他接入点设备发送的频率占用请求的时间戳，则该频率占用请求不能够生效。
可选地，当第一接入点设备不再需要使用该工作频率时，例如休眠或者关机，该方法还可以包括：发送第二频率释放通知，该第二频率释放通知用于告知该第一接入点设备的工作频率将被释放，也即是，该第二频率释放通知用于告知第一接入点设备即将释放工作频率。
可选地，该方法还可以包括：第一接入点设备接收其他接入点设备发送的第三频率释放通知，所述第三频率释放通知用于告知第二接入点设备的工作频率即将被释放。该第三频率释放通知可以是第二接入点设备不再需要使用对应的工作频率时发送的。
第一接入点设备的覆盖范围内的其他接入点设备在收到该频率释放通知后，会更新频率使用记录信息，例如将第一接入点设备的工作频率对应的频率使用记录从频率使用记录信息中删除。
相关技术中，由接入网设备采用集中式资源调度的方式，来控制接入点设备的工作频率，或者，预先为接入点设备配置好工作频率，而在本公开实施例中，接入点设备可以根据被占用频率来选择工作频率，在可用频段与太赫兹频段至少部分重合的情况下，可用频段的频域范围较宽，且该频段的信号的传输距离较短，能够在该频段工作的接入点设备的覆盖范围较小，所以可以通过分布式资源管理的方式来进行频率资源的分配，提高通信效率，并且简化接入点设备的工作流程。
下面以具体的例子对本公开实施例进行示例性说明。
AP1开机，此时，AP1所在区域内不存在除了AP1之外的其他AP正在工作，AP1从广播频率上未接收到频率使用记录信息，则从可用频段中选择了频率1作为工作频率，并在频率1上发送导频信号；并且，第一设备在广播频率上广播第一频率使用记录信息，该第一频率使用记录信息中包括与频率1相关联的使用记录，该与频率1相关联的使用记录包括AP1的标识、频率1的指示信息和时间戳。
随后，AP2和AP3开机，此时AP1正常工作，AP2和AP3从广播频率上接收到AP1发送的第一频率使用记录信息，AP2从剩余频率中确定AP2的频率2，AP3从剩余频率中确定AP3的频率3。AP2发送携带频率2的指示信息的频率占用请求，AP3发送携带频率3的指示信息的频率占用请求。
AP1接收到该AP2和AP3发送的频率占用请求，若频率2和频率3冲突，则根据AP2和AP3发送的频率占用请求中的时间戳，确定时间戳较早的频率占用请求生效，并生成第二频率使用记录信息，假设频率2对应的占用请求生效，则该第二频率使用记录信息包括频率1和频率2对应的频率使用记录。若频率2和频率3不冲突，则生成第二频率使用记录信息，该第二频率使用记录信息中包括频率1、频率2和频率3对应的频率使用记录。AP1广播第二频率使用记录 信息。
AP2接收第二频率使用记录信息，若第二频率使用记录信息中包括频率2对应的频率使用记录，则在频率2上发送导频信号，以便于终端接入AP2。若第二频率使用记录信息中不包括频率2对应的频率使用记录，则重新选择一个频率2并发送新的频率占用请求，直至接收到的频率使用记录信息中包括AP2发送的频率占用请求中的频率2。
AP3接收第二频率使用记录信息，若第二频率使用记录信息中包括频率3对应的频率使用记录，则在频率3上发送导频信号，以便于终端接入AP3。
此外，AP2和AP3在开始发送导频信号后，会在设定的广播频率上周期性广播该第二频率使用记录信息。
AP4开机，接收到AP1、AP2和AP3中的至少一个广播的第二频率使用记录信息，从剩余频率中确定AP4的频率4，AP4发送携带频率4的指示信息的频率占用请求。AP1、AP2和AP3接收到该频率占用请求后，生成第三频率使用记录信息，该第三频率使用记录信息包括频率1至4对应的频率使用记录。AP1、AP2和AP3广播第三频率使用记录信息。AP4接收到该第三频率使用记录信息后，在频率4上发送导频信号，并周期性广播该第三频率使用记录信息。
