Description

通信方法和通信装置
本申请要求于2017年9月27日提交中国专利局、申请号为201710890691.0、申请名称为“通信方法和通信装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，特别涉及通信领域中的通信方法和通信装置。
背景技术
为了提高无线网络的传输速率，增强用户体验，第三代合作伙伴计划(3rd generation partnership project，3GPP)组织正在讨论新一代无线通信技术新无线(New Radio，NR)的标准，即第五代移动通信技术(5-generation，5G)标准。在5G的第一阶段标准化工作中，将主要发展基于长期演进(Long Term Evolution，LTE)的5G技术，即LTE-NR双连接(LTE-NR dual connectivity，LTE-NR DC)。
LTE系统中的基站称为eNB，NR系统中的基站称为gNB，在LTE-NR DC场景下，LTE eNB的覆盖范围较大，但是资源相对比较稀缺，而NR gNB的覆盖范围较小，但是拥有较为丰富的高频段载波。因此，一般将LTE eNB作为主基站(master eNB，MeNB)，而将NR gNB作为辅基站(secondary gNB)。在MeNB下可以有多个小区，可以从该多个小区中选一个小区作为主小区(primary cell，PCell)为终端设备提供服务，而其他小区可以作为辅小区(secondary cell，SCell)，SgNB下的小区一般都作为SCell为终端设备提供服务。另外，在LTE-NR DC场景下，SgNB不能直接接入到核心网，所以NR gNB小区通常是不能支持接入的，必须依附于LTE eNB工作。由于gNB不能直接接入到核心网，所以gNB的小区是无法支持终端设备驻留的。
在LTE-NR DC场景下，通常在LTE的系统信息块(system information block，SIB)中增加一个指示信息，指示终端设备当前网络支持LTE-NR DC，以使得该终端设备一旦检测到SIB中的该指示信息，就显示NR标志(或5G标志)。但是，当前网络支持LTE-NRDC并不是能够针对该网络下的所有终端设备的，由于SIB是LTE的eNB广播的，这样可能导致终端设备并不支持LTE-NR DC，但却显示了NR标志。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
图1示出了本申请实施例应用的通信系统100。该通信系统100可以包括至少两个网络设备：第一网络设备110和第二网络设备120。第一网络设备110和第二网络设备120可以是与终端设备通信的设备，如基站或基站控制器等。每个网络设备可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域(小区)内的终端设备(例如UE)进行通信。在该至少两个网络设备中，第一网络设备110与第二网络设备120采用不同的无线接入技术，具体地，第一网络设备110可以是LTE系统中的演进型基站(evolutional node B，eNB或eNodeB)，第二网络设备120可以是5G系统中的基站gNB。
该无线通信系统100还包括位于网络设备110覆盖范围内的至少一个终端设备130。该终端设备130可以是移动的或固定的。该终端设备130可以指接入终端、用户设备(user equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、未来5G网络中的终端设备或者未来演进的公共陆地移动网络(public land mobile network，PLMN)中的终端设备等。
在LTE-NR DC场景下，第一网络设备的覆盖范围较大，但是资源相对比较稀缺，而第二网络设备的覆盖范围较小，但是拥有较为丰富的高频段载波。因此，以第一网络设备为eNB，第二网络设备为gNB为例，可以将eNB作为主基站(master eNB，MeNB)，而将gNB作为辅基站(secondary gNB)。在MeNB下可以有多个小区，可以从该多个小区中选一个小区作为主小区(primary cell，PCell)为终端设备提供服务，而其他小区可以作为辅小区(secondary cell，SCell)，SgNB下的小区一般都作为SCell为终端设备提供服务。另外，在LTE-NR DC场景下，SgNB不能直接接入到核心网，所以gNB小区通常是不能支持接入的，必须依附于eNB工作。由于gNB不能直接接入到核心网，所以gNB的小区是无法支持终端设备驻留的。
图1示例性地示出了两个网络设备和一个终端设备，可选地，该通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备，本申请实施例对此不做限定。
可选地，该无线通信系统100还可以包括网络控制器、移动管理实体等其他网络实体，本申请实施例不限于此。
图2示出了本申请实施例的通信方法的示意性流程图200。该方法200可以应用于图1所示的通信系统100，但本申请实施例不限于此。
S210，第一网络设备确定控制信息，所述控制信息用于指示第二网络设备的信息，所述第二网络设备与所述第一网络设备采用不同的无线接入技术，所述终端设备驻留在所述第一网络设备的小区上，且所述第二网络设备的小区不支持所述终端设备驻留或不支持所述终端设备初始接入；
具体地，所述终端设备驻留在一个小区，就是指该终端设备已经完成了小区选择或重选择的过程，选择了一个小区并在该小区监听系统信息和寻呼消息，并且在有业务时，可以从该小区执行接入。终端设备选择一个小区作为可驻留小区的评判准则可以包括下列条件：1、该小区是选择的公共陆地移动网络(public land mobile network，PLMN)、注册的PLMN或者等价的PLMN列表中的一个PLMN；2、该小区不是被禁止接入的小区(barred小区)；3、该小区的信号质量满足小区选择的准则；4、该小区是属于一个跟踪区域(tracking area，TA)中的一部分，并且该TA不属于被禁止漫游的TAs，但本申请实施例对此不作限定。应理解，初始接入包括终端设备为了与所选择的小区建立无线资源控制(radio resource control，RRC)连接而发起的接入。举例而言，需要通过随机接入的方式请求接入到所选择的小区。在本申请实施例中，第二网络设备的小区不支持终端设备初始接入包括该终端设备无法通过随机接入的方式请求接入该第二网络设备的小区。
S220，所述第一网络设备向终端设备发送所述控制信息；
则对应地，所述终端设备接收所述第一网络设备发送的所述控制信息；
S230，所述终端设备根据所述控制信息，显示第一标志，所述第一标志为与所述第二网络设备所采用的无线接入技术对应的标志。
具体地，第一网络设备与第二网络设备采用不同的无线接入技术，并且终端设备可以驻留在第一网络设备的小区，不能驻留在第二网络设备的小区或不能接入第二网络设备的小区，在这种情况下，第一网络设备可以向终端设备发送用于指示第二网络设备的信息的控制信息，该终端设备接收该控制信息，并根据该控制信息显示与该第二网络设备所采用的无线接入技术对应的第一标志。
上述控制信息可以为第二网络设备的NR频率信息，也可以为第二网络设备的NR小区信息，还可以为用于指示显示与第二网络设备的无线接入技术对应的标志的指示信息，本申请实施例对此不作限定。该NR频率信息用于指示能够与所述第一网络设备通过长期演进-新无线双连接LTE-NR DC模式提供服务的NR频率，该NR小区信息用于指示能够与所述第一网络设备通过LTE-NR DC模式提供服务的NR小区。
应理解，该第一网络设备可以是LTE网络设备，例如，eNB，该第二网络设备可以是NR网络设备，例如，gNB，对应地，第一网络设备的小区可以为LTE小区，第二网络设备的小区可以为NR小区，但本申请实施例对此不作限定。还应理解，上述第一标志可以为5G标志，也可以为NR标志，本申请实施例对此也不作限定。
在LTE-NR DC场景中，一般情况下，可以在LTE的系统信息块(system information block，SIB)中增加一个指示信息，指示终端设备当前网络支持LTE-NR DC，以使得该终端设备一旦检测到SIB中的该指示信息，就显示NR标志(或5G标志)。但是，当前网络支持LTE-NR DC并不是能够针对该网络下的所有终端设备的，由于SIB是LTE的eNB广播的，这样可能导致终端设备并不支持LTE-NR DC，但却显示了NR标志。
而本申请实施例的通信方法，通过第一网络设备向终端设备发送用于指示第二网络设备的控制信息，能够使得终端设备根据该控制信息显示与第二网络设备所采用的无线接入技术对应的标志，有利于提高终端设备显示无线接入技术的标志的准确性，从而提高用户的满意度。
作为一个可选的实施例，所述控制信息为所述第二网络设备的NR频率信息或所述第 二网络设备的NR小区信息，所述NR频率信息用于指示能够与所述第一网络设备通过长期演进-新无线双连接LTE-NR DC模式提供服务的NR频率，所述NR小区信息用于指示能够与所述第一网络设备通过LTE-NR DC模式提供服务的NR小区，
所述终端设备根据所述控制信息，显示所述第一标志，包括：
所述终端设备根据所述NR频率信息或所述NR小区信息，显示所述第一标志；或
所述终端设备根据所述NR频率信息或所述NR小区信息，以及所述终端设备的能力，显示所述第一标志。
具体地，上述控制信息可以为第二网络设备的NR频率信息或第二网络设备的NR小区信息，即第一网络设备可以告知该终端设备能够为该终端设备提供的NR频率或NR小区，该终端设备接收到该NR频率信息或NR小区信息之后，可以直接显示上述第一标志，也可以确定是否要显示上述第一标志，在确定要显示该第一标志的情况下，显示该第一标志。即该终端设备可以根据该NR频率信息或NR小区信息来显示该第一标志，该终端设备也可以根据该NR频率信息或NR小区信息，以及该终端设备的能力来显示该第一标志，本申请实施例对此不作限定。
应理解，该NR频率信息中可以包括频率配置信息、参考信号配置信息等。且该NR频率信息所指示的NR频率，可以对应一个NR小区，也可以对应多个NR小区，本申请实施例对此不作限定。该NR小区信息可以包括该NR小区的频率信息，还可以包括该NR小区的小区标识信息、该NR小区的参考信号配置信息等等，本申请实施例对此也不作限定。
在一种可能的实现方式中，第一网络设备向终端设备发送上述NR频率信息或NR小区信息，该终端设备接收到该NR频率信息或NR小区信息之后，显示该第一标志。具体地，该终端设备的接入层可以在接收到第一网络设备发送的NR频率信息或NR小区信息之后，向该终端设备的高层指示显示该第一标志。
在另一种可能的实现方式中，第一网络设备向终端设备发送上述NR频率信息或NR小区信息，该终端设备接收到该NR频率信息或NR小区信息之后，需要判断是否显示该第一标志。在该终端设备确定可以显示该第一标志的情况下，该终端设备才会显示该第一标志。应理解，该终端设备可以通过多种方式确定是否需要显示该第一标志，本申请实施例对此不作限定。
作为一个可选的实施例，所述终端设备根据所述NR频率信息或所述NR小区信息，以及所述终端设备的能力，显示所述第一标志，包括：

在所述终端设备的能力支持通过所述NR频率或所述NR小区进行LTE-NR DC模式工作的情况下，所述终端设备显示所述第一标志。
具体地，该终端设备可以先确定自身的能力，即该终端设备能够支持的频率，并判断自身是否能够支持该NR频率或该NR小区，若该终端设备无法支持第一网络设备发送的NR频率信息所指示的NR频率，或无法支持该第一网络设备发送的NR小区信息所指示的NR小区(具体可以为不支持该NR小区的频率)，那么该终端设备可以不显示该第一标志。换句话说，该终端设备只有在自身的能力支持上述NR频率信息所指示的NR频率 或自身的能力支持上述NR小区信息所指示的NR小区的情况下，才显示该第一标志。这样，能够提高终端设备显示第一标志的准确性，从而提高用户的满意度。
可选地，该终端设备可以在确定自身的能力之后，进一步地确定该终端设备的能力是否同时支持LTE频率和NR频率，即确定该终端设备的能力是否支持该NR频率下的LTE-NR DC模式，若该终端设备无法支持通过该NR频率进行LTE-NR DC模式工作，那么该终端设备可以不显示该第一标志。即该终端设备只有在自身的能力支持通过上述NR频率进行LTE-NR DC模式工作的情况下，才显示该第一标志。这样，能够提高终端设备显示第一标志的准确性，从而提高用户的满意度。
可选地，该终端设备可以在确定自身的能力之后，进一步地确定该终端设备的能力是否同时支持LTE频率和该NR小区信息所指示的NR小区的频率，若该终端设备无法支持通过该NR小区进行LTE-NR DC模式工作，那么该终端设备可以不显示该第一标志。即该终端设备只有在自身的能力支持通过上述NR小区进行LTE-NR DC模式工作的情况下，才显示该第一标志。这样，能够提高终端设备显示第一标志的准确性，从而提高用户的满意度。

具体地，该终端设备进行信号测量，确定是否能够检测到该NR频率或该NR小区的信号，在能够在检测到该NR频率或该NR小区的信号的情况下，才显示该第一标志。或者，该终端设备可以在能够检测到该NR频率或该NR小区的信号并且该NR频率或该NR小区的信号的质量大于第一阈值的情况下，才显示该第一标志，本申请实施例对此不作限定。这样，能够提高终端设备显示第一标志的准确性，从而提高用户的满意度。
应理解，上述第一阈值可以是该终端设备自身确定的，也可以是该第一网络设备预先配置给该终端设备的，例如，该第一网络设备在发送给该终端设备的系统信息中携带该第一阈值，也可以是该第一网络设备在向终端设备发送上述NR频率信息该上述NR小区信息的时候，将该第一阈值一起发送给该终端设备，本申请实施例对此不作限定。

作为一个可选的实施例，所述NR频率信息携带在所述第二网络设备的NR小区信息中。
具体地，上述NR频率信息可以携带在第二网络设备的NR小区信息中，该NR小区信息用于指示能够与该第一网络设备通过LTE-NR DC模式提供服务的NR小区，因此，该NR小区信息可以包括该NR小区的频率，即上述NR频率信息。应理解，该NR小区 信息所指示的NR小区可以是一个小区，也可以是多个小区，本申请实施例对此也不作限定。
作为一个可选的实施例，所述控制信息携带在系统信息SI中。
具体地，该第一网络设备可以将上述控制信息携带在系统信息(system information，SI)中，由于系统信息是第一网络设备进行广播的，这样，该终端设备可以在接入该第一网络设备之前，通过该系统信息获取该控制信息，进而获取该第二网络设备的信息，显示出该第一标志。
