为了降低回传链路的部署复杂性，在5G项目的研究讨论中，提出了前传回传一体化的方案，也即基站和用户设备(User Equipment，简称为UE)之间的数据传输与基站和核心网之间的数据传输都采用相同的无线通信系统协议通过无线链路进行传输，为了实现前传回传一体化，针对5G系统需要提出一种新的无线回传实现方案，来确保只具备无线回传能力的基站也可以通过具备有线回传能力的基站实现回传。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
本公开提供的技术方案中，核心网覆盖范围内可以具有两种类型的基站，参见图1B，图1B中核心网覆盖范围内有具备有线回传能力的基站，如标记11所指示的基站，具备有线回传能力的基站与核心网之间部署了有线回传链路；核心网覆盖范围内还有具备无线回传能力的基站，如标记12所指示的基站为具备无线回传能力的基站， 具备无线回传能力的基站与核心网之间没有部署有线回传链路，需要通过建立与具备有线回传能力的基站之间建立无线连接来实现无线回传。
图1A是根据一示例性实施例示出的一种无线回传的实现方法的流程图，图1B是根据一示例性实施例示出的一种无线回传的实现方法的应用场景图一，图1C是根据一示例性实施例示出的一种无线回传的实现方法的应用场景图二；该无线回传的实现方法可以应用在具备有线回传能力的基站上，如图1A所示，该无线回传的实现方法包括以下步骤101-103：
在步骤101中，接收接入请求消息，接入请求消息中携带有身份标识信息。
在一实施例中，接入请求消息可以为相关技术中的随机接入流程的第一个消息MSG1或者随机接入流程的第三个消息MSG3，可在接入请求消息中携带设备的身份标识信息，身份标识信息用于指示请求接入的设备的设备类型；在一实施例中，设备类型可以为具备无线回传能力的基站或者为用户设备。在一实施例中，若请求接入的设备为具备无线回传能力的基站，则可在接入请求消息中携带身份标识信息，若请求接入的设备为普通的用户设备，则可不在接入请求消息中携带身份标识信息。
在一实施例中，接入请求消息还可以为新定义的一个专属消息，用于具备无线回传能力的基站在请求建立与具备有线回传能力的基站之间的无线连接时使用，接入请求消息中还可以携带身份标识信息，指示请求接入的为具备无线回传能力的基站。
在步骤102中，在基于身份标识信息确定请求接入的设备为只具备无线回传能力的第一基站时，基于与核心网之间的有线回传链路的可用有线带宽确定是否允许第一基站接入。
在一实施例中，具备有线回传能力的第二基站可基于与核心网设备之间的有线回传链路的可用有线带宽可以基于有线回传链路的总的有线带宽与已用带宽的差值得到，例如，有线回传链路的总带宽为6.4GB/s，而已用带宽为3.2GB/s，则剩余的可用有线带宽为3.2GB/s。
在一实施例中，基于与核心网之间的有线回传链路的可用有线带宽确定是否允许第一基站接入的实现方式可参见图2和图3所示实施例的描述，这里先不详述。
在步骤103中，向第一基站返回响应消息，响应消息用于指示是否允许第一基站接入。
在一实施例中，若接入请求消息为随机接入流程中的第一个消息MSG1，则响应消息对应为第二个消息MSG2，其中携带有是否允许第一基站接入的指示信息；在一实施例中，若接入请求消息为随机接入流程中的第三个消息MSG3，则响应消息可 以为随机接入流程的第四个消息MSG4，其中携带有是否允许第一基站接入的指示信息，基于该第四个消息MSG4，即可建立第一基站和第二基站之间的无线连接，也即数据和信令连接。
在一实施例中，若接入请求消息为新定义的一个专属消息，则该响应消息也可以为该专属消息对应的一个新的响应消息。
在一实施例中，若具备有线回传能力的第二基站允许具备无线回传能力的第一基站接入，则第一基站可与第二基站建立无线连接，第一基站可通过该无线连接将回传数据发送至第二基站，第二基站再通过有线回传链路，如光纤链路传输至核心网设备，由此实现第一基站的无线回传。
在一示例性场景中，如图1C所示，包括具备无线回传能力的第一基站10、具备有线回传能力的第二基站20、核心网设备30，其中，第二基站20与核心网设备30之间具有有线回传链路，第二基站20可接收到接入请求消息，并且基于接入请求消息中的身份标识信息确定出请求接入的设备为具备无线回传能力的第一基站10时，第二基站20可基于自己的当前状态，如当前的可用有线带宽确定时否允许第一基站10接入，在确定允许第一基站10接入时，第一基站10通过与具备有线回传能力的第二基站20之间的无线连接实现无线回传。
本实施例通过上述步骤101-步骤103，具备有线回传能力的第二基站在接收到接入请求消息后，若基于接入请求消息中的身份标识信息确定出请求接入的设备是具备无线回传能力的第一基站，则可基于与核心网之间的有线回传链路的可用有线带宽确定是否允许第一基站接入，并基于判断结果返回对应的响应消息，由此可以实现只具备无线回传能力的第一基站与具备有线回传能力的第二基站之间的建立无线连接，实现无线回传。
具体如何实现无线回传的，请参考后续实施例。
下面以具体实施例来说明本公开实施例提供的技术方案。
图2是根据一示例性实施例示出的又一种无线回传的实现方法的流程图；本实施例利用本公开实施例提供的上述方法，以具备有线回传能力的基站如何确定是否允许具备无线回传能力的基站接入为例进行示例性说明，如图2所示，包括如下步骤：
在步骤201中，接收接入请求消息，接入请求消息中携带有身份标识信息。
在步骤202中，在基于身份标识信息确定请求接入的设备为只具备无线回传能力的第一基站时，基于与核心网之间的有线回传链路的可用有线带宽确定是否允许第一基站接入，执行步骤203或者步骤205。
在一实施例中，步骤201和步骤202的描述可参见图1A所示实施例的步骤101和步骤102的描述，这里不再详述。
在步骤203中，若可用有线带宽高于预设门限值，确定允许第一基站接入，执行步骤204。
在一实施例中，预设门限值可以为一个固定值，由系统预先配置或者由基站自身设置。由于具备有线回传能力的第二基站也需要服务用户设备，为了服务已接入或者待接入的用户设备，第二基站需要预留不低于预设门限值的有线带宽。例如，第二基站的有线回传链路的可用有线带宽为3.2GB/s，预设门限值为1.6GB/s，则第二基站可以确定允许第一基站接入。
在一实施例中，预设门限值可以为一个动态变化的值，由第二基站基于自己当前接入的用户设备的数量和/或基于历史接入信息确定出的待接入的用户设备的数量，确定出的用于服务用户设备的有线带宽确定，例如，第二基站基于已接入的用户设备的数量和/或待接入的用户设备的数量确定出服务用户设备的有线带宽为3.2GB/s，而当前已经用于服务用户设备的有线带宽为1.8GB/s，则可设置预设门限值为1.4GB/s，当前的可用有线带宽为3.2GB/s，高于1.4GB/s，因此第二基站可以确定允许第一基站接入。
在步骤204中，向第一基站返回响应消息，响应消息指示允许第一基站接入，流程结束。
在一实施例中，步骤204的描述可参见图1A所示实施例的步骤103的描述，这里不再详述。
在步骤205中，若可用有线带宽不高于预设门限值，确定拒绝第一基站接入。
在一实施例中，关于预设门限值的描述，可参见步骤203的描述，这里不再详述。
在步骤206中，向第一基站返回响应消息，响应消息用于指示不允许第一基站接入。
本实施例中，具备有线回传能力的第一基站在接收到具备无线回传能力的第二基站发送的接入请求后，可基于可用有线带宽与预设门限值的比较结果确定是否允许第一基站接入，预设门限值可以为一个固定值，也可以为一个动态变化的值，由第二基站为已接入的或者待接入的用户设备预留，由此可以实现第二基站在确定不会影响服务用户设备的前提下决定是否允许第一基站接入，以避免第二基站在自身情况不允许第一基站接入时接入第一基站所导致的第一基站和第二基站均不能正常服务用户设 备的问题。
图3是根据一示例性实施例示出的一种无线回传的实现方法的流程图；本实施例利用本公开实施例提供的上述方法，以具备有线回传能力的基站如何确定是否允许具备无线回传能力的基站接入为例进行示例性说明，如图3所示，包括如下步骤：
在步骤301中，接收接入请求消息，接入请求消息中携带有身份标识信息。
在步骤302中，在基于身份标识信息确定请求接入的设备为只具备无线回传能力的第一基站时，基于与核心网之间的有线回传链路的可用有线带宽确定是否允许第一基站接入，执行步骤303或者步骤305。
在一实施例中，步骤301和步骤302的描述可参见图1A所示实施例的步骤101和步骤102的描述，这里不再详述。
在步骤303中，若可用有线带宽高于最小回传带宽，确定允许第一基站接入，执行步骤304。
在一实施例中，接入请求消息中还可以携带有第一基站所需的最小回传带宽，如第一基站所需的最小回传带宽为0.8GB/s，而第二基站剩余的可用有线带宽为1.6GB/s，则第二基站可以确定允许第一基站接入。
在步骤304中，向第一基站返回响应消息，响应消息指示允许第一基站接入，流程结束。
在一实施例中，步骤204的描述可参见图1A所示实施例的步骤103的描述，这里不再详述。
在步骤305中，若可用有线带宽不高于最小回传带宽，确定拒绝第一基站接入。
在步骤306中，向第一基站返回响应消息，响应消息用于指示不允许第一基站接入。
本实施例中，第二基站可以基于请求接入的第一基站的最小回传带宽和可用有线带宽确定是否允许第一基站接入，以实现在允许第一基站接入后能为第一基站提供不低于最小回传带宽的回传带宽，保证第一基站在接入第二基站后，能实现正常的无线回传，保证数据传输的效率。
图4是根据一示例性实施例示出的一种无线回传的实现方法的流程图；本实施例的无线回传的实现方法可应用在具备无线回传能力的基站上，如图4所示，包括以下步骤401-403：
在步骤401中，在搜寻到具备有线回传能力的第二基站时，向第二基站发送接入请求消息，接入请求消息中携带身份标识信息。
在一实施例中，身份标识信息用于指示第二基站自己为一个具备无线回传能力的基站，而不是一个普通的用户设备。
在一实施例中，接入请求消息可以为相关技术中的随机接入流程的第一个消息MSG1或者随机接入流程的第三个消息MSG3。
在一实施例中，接入请求消息还可以为新定义的一个专属消息，用于具备无线回传能力的基站在请求建立与具备有线回传能力的基站之间的无线连接时使用，接入请求消息中还可以携带身份标识信息，指示请求接入的为具备无线回传能力的基站。
在步骤402中，监听第二基站基于身份标识信息返回的响应消息。
在一实施例中，若接入请求消息为随机接入流程中的第一个消息MSG1，则响应消息可以为随机接入流程中的第二个消息MSG2；在一实施例中，若接入请求消息为随机接入流程中的第三个消息MSG3，则响应消息可以为随机接入流程的第四个消息MSG4。
在一实施例中，若接入请求消息为新定义的一个专属消息，则该响应消息也可以为该专属消息对应的一个新的响应消息。
在步骤403中，在监听到允许接入的响应消息时，建立与第二基站之间的无线连接，无线连接用于实现第一基站的无线回传。
在一实施例中，具备有线回传能力的第二基站为与核心网之间具有有线传输链路，如光纤链路；而具备无线回传能力的第一基站为与核心网之间不具有有线传输链路，可借助与具备有线回传能力的第二基站之间的无线连接实现无线回传的基站。
在一示例性场景中，如图1C所示，包括具备无线回传能力的第一基站10、具备有线回传能力的第二基站20、核心网设备30，其中，第一基站10可在开机后搜寻周边具备有线回传能力的第二基站20，并在搜寻到第二基站20后向第二基站20发送接入请求消息，在接入请求消息中指示第二基站20自己为具备无线回传能力的基站，在监听到第二基站20基于接入请求消息返回的允许接入的响应消息时，建立与第二基站之间的无线连接，并通过该无线连接实现无线回传。
本实施例中，通过步骤401-步骤403，具备无线回传能力的基站可建立与具备有线回传能力的基站的无线连接，进而实现无线回传。

在步骤501中，在搜寻到具备有线回传能力的第二基站时，向第二基站发送接 入请求消息，接入请求消息中携带身份标识信息。
在步骤502中，监听第二基站基于身份标识信息返回的响应消息，执行步骤503或者步骤504。
在一实施例中，步骤501-步骤502的描述可参见图4所示实施例的步骤401-步骤402的描述，这里不再详述。
在步骤503中，在监听到拒绝接入的响应消息时，继续搜寻具备有线回传能力的其他基站，执行步骤501。
在一实施例中，在监听到拒绝接入的响应消息时，第一基站可以继续搜寻具备有线回传能力的基站，并在搜寻到具备有线回传能力的其他基站时，向搜寻到的其他基站发送接入请求消息，尝试接入具备有线回传能力的其他基站。
在一实施例中，第一基站在成功接入具备有线回传能力的基站之前，不能发送发送广播消息，以免有接入需求的用户设备接入而不能为其提供服务。
在步骤504中，在监听到允许接入的响应消息时，建立与第二基站之间的无线连接，无线连接用于实现第一基站的无线回传。
在步骤505中，在建立与第二基站之间的无线连接之后，发送广播消息，广播消息用于有接入需求的用户设备接入。
本实施例中，公开了具备无线回传能力的第一基站如何尝试建立与具备有线回传能力的基站之间的无线连接以实现无线回传，并且禁止第一基站在成功建立与具备有线回传能力的基站之间的无线连接之前发送广播消息，以免有接入需求的用户设备接入而不能为其提供服务。
