Description

设备识别方法以及装置 技术领域
本申请实施例涉及通信技术领域。
背景技术
与传统的3G(第三代移动通信技术)、4G(第四代移动通信技术)系统相比，5G(第五代移动通信技术)系统能够提供更大的带宽以及更高的数据率，并且能够支持更多类型的终端和垂直业务。为此，5G系统的部署频率通常明显高于3G和4G系统。例如，5G系统可以部署在毫米波波段。
然而，承载频率越高，信号在传输过程中遇到的衰落越严重。因此，在5G系统的实际部署中，特别是在毫米波段，如何更好的增强小区覆盖，成为亟待解决的问题。
应该注意，上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
为了更好的解决蜂窝移动通信系统在实际部署中的覆盖问题，采用射频中继器(RF Relay/Repeater)放大和转发终端设备与网络设备之间的通信信号，是比较常用的部署手段。射频中继器在3G系统和4G系统的实际部署中具有较为广泛的应用。通常来说，射频中继器是一种在射频域放大和转发网络设备与终端设备往来信号的设备。
针对5G系统在部署中遇到的覆盖问题，采用射频中继器进行覆盖增强是可行的解决方案之一。但是，传统中继器不具备与网络设备通信的能力，不能从网络设备处获得上下行配置的相关信息。因此，这样的中继器配置在5G系统中，虽然能够帮助增强信号强度，但是不够灵活而无法应对复杂的环境变化，进而无法达到在3G系统和4G系统中部署相同射频中继器的同等效果。
智能中继器(smart repeater)是对传统射频中继器的一种增强，具有接收和处理来自网络的边控制信息(side control information)的能力。边控制信息能允许智能中 继器以更有效的方式执行其放大和转发操作。由此可以减少不必要的噪声放大、有更好的空间方向性的传输和接收以及简化的网络集成。
但发明人发现，对于部署了智能中继器的场景，在智能中继器接入网络的过程中，目前还没有识别智能中继器的方法，即，目前还没有智能中继器的确定方法。
针对上述问题的至少之一，本申请实施例提供一种设备识别方法以及装置。

接收单元，其接收第一设备发送的第一信息，其中，
所述第一信息用于指示所述第一设备是中继器或确定所述第一设备作为中继器接入网络；或者，所述第一信息是中继器特定的第一信息；或者，所述第一信息在第一资源上发送，所述第一资源是中继器特定的第一资源。
根据本申请实施例的另一个方面，提供一种设备识别装置，应用于第一设备，其特征在于，所述装置包括：
发送单元，其所述第一设备向第一网络设备发送第一信息，所述第一信息用于指示所述第一设备是中继器或确定所述第一设备作为中继器接入网络；或者，所述第一信息是中继器特定的第一信息；或者，所述第一信息在第一资源上发送，所述第一资源是中继器特定的第一资源。
本申请实施例的有益效果之一在于：根据第一信息和/或第一资源能够使得网络设备确定第一设备是智能中继器或者确定第一设备作为智能中继器接入网络，进一步的能够使得网络设备可以识别并且区分第一设备是中继器还是常规终端设备，以便网络对中继器的接入、消息传输、认证以及鉴权等进行单独处理，从而达到中继器的灵活部署，降低网络部署成本。

对于部署了智能中继器的场景，在智能中继器与网络设备进行通信时，网络设备需要识别出智能中继器以便与智能中继器进行后续的通信。此外，如果智能中继器直接沿用当前通信标准中识别常规的终端设备的方法，那么，网络设备仍然无法区分智能中继器与常规的终端设备。因此，需要为智能中继器引入特定的识别方法。
针对上述问题，下面结合附图对本申请实施例的各种实施方式进行说明。这些实施方式只是示例性的，不是对本申请的限制。
第一方面的实施例
本申请实施例提供一种设备识别方法，从第一网络设备侧进行说明。
图4是本申请实施例的设备识别方法的一示意图，如图4所示，该方法包括：
401：接收第一设备发送的第一信息；
其中，该第一信息用于指示该第一设备是中继器或确定该第一设备作为中继器接入网络；或者，该第一信息是中继器特定的第一信息；或者，该第一信息在第一资源上发送，该第一资源是中继器特定的第一资源。
由此，根据第一信息和/或第一资源能够使得第一网络设备确定第一设备是智能中继器或者确定第一设备作为智能中继器接入网络，进一步的能够使得第一网络设备可以识别并且区分第一设备是中继器还是常规终端设备，进一步的以便网络对中继器的接入、消息传输、认证以及鉴权等进行单独处理，从而达到中继器的灵活部署，降低网络部署成本。
值得注意的是，以上附图4仅对本申请实施例进行了示意性说明，但本申请不限于此。例如还可以增加其他的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图4的记载。
在一些实施例中，该第一信息和/或第一资源可以是随机接入过程中的第一信息和/或随机接入过程中使用的第一资源，或者，该第一信息也可以是随机接入过程完成后的第一信息，为了便于理解，以下先对随机接入过程进行示例性的说明。
在一些实施例中，在部署了智能中继器的场景下，智能中继器需要通过随机接入 过程接入网络。例如，通过4步(4-step)的随机接入过程，或者2步(2-step)随机接入过程。随机接入过程包括基于竞争的随机接入过程和/或基于非竞争的随机接入过程；随机接入过程还包括初始随机接入过程和/或无线资源控制重建(Radio Resource Control，RRC Reestablishment)过程中的随机接入和/或切换(Handover)过程中的随机接入等，本申请不对此进行限制。
以下对于中继器与第一网络设备进行4步(4-step)的随机接入过程以及2步(2-step)随机接入过程进行简单举例。
例如，以基于竞争的随机接入过程为例，4-step随机接入过程包括：步骤1，中继器在随机接入资源上发送消息1(MSG1)给第一网络设备，例如发送随机接入前导码(preamble)；步骤2，第一网络设备发送消息2(MSG2)给中继器，例如发送随机接入回复(random access response,RAR)，其可以指示临时无线网络标识(Temporory RadioNetworkTemporaryIdentifier，TC-RNTI)，并且为后续的消息3(MSG3)分配资源等；步骤3，中继器发送消息3(MSG3)给第一网络设备，例如调整上行定时等；步骤4，第一网络设备发送消息4(MSG4)给中继器，指示基于竞争的随机接入成功，并且将TC-RNTI升级成为C-RNTI等。在完成上述4-step随机接入过程后，中继器可以进一步发送随机接入过程完成后的第一消息，例如可以称为消息5(MSG5)，进而中继器可以与第一网络设备进行后续的信令传输。在一些实施例中，上述MSG1-MISG5的具体内容可参考现有技术，本申请对此不进行一一列举。
例如，以基于竞争的随机接入过程为例，2-step随机接入过程包括：步骤A，中继器在随机接入资源上发送消息A(MSGA)给第一网络设备，例如发送随机接入前导码(preamble)和/或上行数据；步骤B，第一网络设备发送消息B(MSGB)给中继器，例如发送随机接入回复(random access response,RAR)，其可以指示基于竞争的随机接入成功等。在完成上述2-step随机接入过程后，中继器可以与第一网络设备进行后续的信令传输。在一些实施例中，上述MSGA-MSGB的具体内容可参考现有技术，本申请对此不进行一一列举。

在一些实施例中，第一网络设备在收到第一设备发送的UE能力信息(UECapabilityInformation)消息或UE辅助信息(UEAssistanceInformation)消息时，确定是否携带了该第二指示信息，和/或确定该第二指示信息的值，以此确定第一设备是否为中继器作为中继器接入网络。
由此，该第二指示信息可以显式的指示第一设备为中继器或确定该第一设备作为中继器接入网络，第一网络设备在接收到上述第二指示信息后，即可识别出第一设备为中继器或确定该第一设备作为中继器接入网络。由此，实现了中继器的识别过程。
例如，该第三指示信息是该UE能力信息(UECapabilityInformation)消息或该UE辅助信息(UEAssistanceInformation)消息中指示第一能力的信息，该第一能力是中继器特定的能力，包括，在UE能力信息(UECapabilityInformation)消息或UE辅助信息(UEAssistanceInformation)消息中现有或新增比特字段(域)，来指示该第一设备具备第一能力。例如，该比特字段的取值类型包括多种能力，该多种能力中至少包括一种能力是中继器特定的能力，第一网络设备在收到第一设备发送的UE能力信息(UECapabilityInformation)消息或UE辅助信息(UEAssistanceInformation)消息中的第三指示信息时，在该第三指示信息的取值为中继器特定的能力(第一能力)对应的类型时，确定第一设备是否为中继器或作为中继器接入网络。
由此，该第三指示信息通过指示中继器特定的第一能力，可以隐式的指示第一设备为中继器或确定该第一设备作为中继器接入网络，第一网络设备在接收到上述第三指示信息后，即可识别出第一设备是否具备中继器特定的第一能力，进而即可识别出第一设备为中继器或确定该第一设备作为中继器接入网络。由此，实现了中继器的识别过程。
