技术领域
本公开涉及移动通信接入技术，特别是一种接入处理方法、基站及移动通信终端。
背景技术
移动通信已经深刻地改变了人们的生活，但人们对更高性能的移动通信的追求从未停止。为了应对未来爆炸性的移动数据流量增长、海量的设备连接以及不断涌现的各类新业务和应用场景，第五代移动通信系统将应运而生。
国际电信同盟ITU定义了第五代移动通信系统典型的三大应用场景并制定了八个关键指标能力的需求。如何满足这些场景和关键能力的需求成为摆在通信产业界面前的关键问题，综合考虑需求、技术发展趋势以及网络平滑演进等因素，第五代移动通信系统应该同时存在新空口和第四代移动通信系统演进空口两条路线。在第五代移动通信系统商用之前，第四代移动通信系统将会持续演进以满足日益增长的容量需求。因此，第四代移动通信演进系统和第五代移动通信系统将在很长一段时间内共存和互操作。
考虑到相关技术中的第四代移动通信系统向第五代移动通信系统的演进，如图1所示，传统接入至第四代移动通信演进系统的核心网EPC的长期演进基站LTE eNB需要同时连接至EPC和第五代移动通信系统的新核心网。
然而，从演进的角度来看，未来的移动通信终端应该能够同时支持EPC的接入和5G新核心网的接入，而LTE eNB和演进后的eLTE eNB也是共存的状态。因此，有必要提供一种技术方案，实现能够同时连接至EPC和5G新核心网的移动通信终端到核心网的接入。

具体实施方式
本公开实施例中，同时能够连接到第一网络和第二网络的移动通信终端发送携带有目标非接入层NAS消息的接入请求后，基站会向自己所连接的目标核心网发送该目标NAS消息，由目标核心网依据其中目标NAS消息决定是否允许接入。因此，本公开实施例中，能够连接到多种核心网的移动通信终端能通过不同的基站接入到核心网，为用户提供服务。
本公开的一些实施例的接入处理方法，用于一基站时，如图2所示，所述接入处理方法包括：
步骤201，接收能够连接到第一网络和第二网络的移动通信终端发送的携带有目标非接入层NAS消息的接入请求；所述目标NAS消息包括对应于所述第一网络的第一NAS消息和/或对应于所述第二网络的第二NAS消息；
步骤202，确定目标核心网，所述目标核心网为对应于所述第一网络的第一核心网和对应于所述第二网络的第二核心网中所述基站能够连接的核心网；
步骤203，向所述目标核心网发送所述目标NAS消息。
本公开的一些实施例中，同时能够连接到第一网络和第二网络的移动通信终端发送携带有目标非接入层NAS消息(可以是对应于所述第一网络的第一NAS消息，也可以是对应于所述第二网络的第二NAS消息，还可以同时包括第一NAS消息和第二NAS消息)的接入请求后，基站会向自己所连接的目标核心网发送该目标NAS消息，由目标核心网依据其中目标NAS消息决定是否允许接入。通过上述的流程，能够连接到多种核心网的移动通信终端能通过不同的基站连接到核心网，由核心网决定是否允许接入。
在本公开的一些实施例中，由于所述目标NAS消息可以是第一NAS消息和第二NAS消息中的任意一个或两个，而仅就NAS消息而言，其属于非接入层的消息，对属于接入层的基站而言是不可知的。因此有可能基站确定的目标核心网对应的网络与目标NAS消息对应的网络并不相同，这种情况下，目标核心网会拒绝接入，为保证移动通信终端能够接入到合适的核心网，本公开的一些实施例的接入处理方法中，将该接入拒绝消息返回给移动通信终端，以通知移动通信终端更换NAS消息重新发起接入流程。
如图3所示，本公开的一些实施例的接入处理方法包括：
步骤201，接收能够连接到第一网络和第二网络的移动通信终端发送的携带有目标非接入层NAS消息的接入请求；所述目标NAS消息包括对应于所述第一网络的第一NAS消息和/或对应于所述第二网络的第二NAS消息；
步骤202，确定目标核心网，所述目标核心网为对应于所述第一网络的第一核心网和对应于所述第二网络的第二核心网中所述基站能够连接的核心网；
步骤203，向所述目标核心网发送所述目标NAS消息。
步骤204，接收所述目标核心网在所述目标NAS消息对应的网络和所述目标核心网对应的网络不同时返回的接入拒绝消息；
步骤205，发送接入拒绝消息到所述移动通信终端，通知所述移动通信终端更换NAS消息重新发起接入流程。
本公开的一些实施例的接入处理方法中，当基站确定的目标核心网对应的网络与目标NAS消息对应的网络不相同(即NAS不匹配)时，基站会转发目标核心网发送的接入拒绝消息到移动通信终端，而由移动通信终端选择新的NAS消息重新发起接入流程，实现到目标核心网的接入。
对此举例说明如下。
假定而终端发送的接入请求携带的是对应于第二网络的第二NAS消息，而基站选择的目标核心网是对应于所述第一网络的第一核心网(可能是由于基站仅能连接对应于所述第一网络的第一核心网，也可能是基站能够同时连接第一核心网和第二核心网，但基于选择策略选择的第一核心网)，此时由于基站确定的目标核心网对应的第一网络与目标NAS消息对应的第二网络并不相同，因此第一核心网会拒绝接入。
而终端在收到该接入拒绝消息后，重新发送的接入请求携带的是对应于第一网络的第一NAS消息，此时基站确定的目标核心网对应的第一网络与目标NAS消息对应的第一网络相同，因此移动通信终端能够接入第一核心网，并为用户提供服务。
在上述的实施例中，当基站确定的目标核心网对应的网络与目标NAS消息对应的网络不相同时，通过利用新的NAS消息重新接入，保证移动通信终端能够接入到合适的核心网，为用户提供服务。
但从本公开的一些实施例的流程可以发现，其可能会导致多次接入流程，降低接入速度。其中一种导致接入失败的情况是：基站仅能连接一种核心网，而移动通信终端发送的NAS消息对应的网络恰好与基站所能连接的唯一核心网对应的网络不同。
因此，在本公开的一些实施例中，为避免由于上述情况导致的重新接入，由基站告知移动通信终端基站能够连接的核心网对应的网络的网络信息，使得移动通信终端在发起接入流程时能够选择所述基站能够连接的核心网对应的网络所对应的NAS消息。
如图4所示，本公开的一些实施例接入处理方法，包括：
步骤206，发送指示所述基站能够连接的核心网对应的网络的网络信息；
步骤201，接收能够连接到第一网络和第二网络的移动通信终端发送的携带有目标非接入层NAS消息的接入请求；所述目标NAS消息为：所述移动通信终端根据所述网络信息从所述第一NAS消息和第二NAS消息中，选择的对应的网络为基站能够连接的核心网对应的网络的NAS消息；
步骤202，确定目标核心网，所述目标核心网为对应于所述第一网络的第 一核心网和对应于所述第二网络的第二核心网中所述基站能够连接的核心网；
步骤203，向所述目标核心网发送所述目标NAS消息。
在本公开的一些实施例中，由于基站预先告知其能够连接的核心网对应的网络的网络信息，使得移动通信终端能够选择基站能够连接的核心网对应的网络对应的NAS消息，避免了基站唯一能够连接的核心网对应的网络与目标NAS消息对应的网络不一致导致的重新接入流程，加快了接入速度。
如基站仅能连接到第一核心网，则在移动通信终端获悉所述基站仅能连接到第一核心网时，则只会选择第一网络对应的NAS消息发起接入，而不会选择第二网络对应的NAS消息发起接入。反之同样如此。
从本公开的一些实施例的流程可以发现，如果目标NAS消息和目标核心网随机选择，可能会出现重新接入。而本公开的一些实施例解决了其中一种情况，而在另一种情况下，基站同时能够连接到第一核心网和第二核心网，但基于选择策略选择的核心网对应的网络和目标NAS消息对应的网络不一致所导致的重新接入，本公开的一些实施例并不能解决。
为解决上述问题，本公开的一些实施例中，由移动通信终端在接入请求中携带有所述目标NAS消息对应的网络的网络标识，使得基站能够选择匹配的核心网(即核心网对应的网络和NAS消息对应的网络相同)，避免接入失败。
如图5所示，本公开的一些实施例的接入处理方法包括：
步骤206，发送指示所述基站能够连接的核心网对应的网络的网络信息；
步骤207，接收能够连接到第一网络和第二网络的移动通信终端发送的携带有目标非接入层NAS消息和所述目标NAS消息对应的网络的网络标识的接入请求；所述目标NAS消息为：所述移动通信终端根据所述网络信息从所述第一NAS消息和第二NAS消息中选择的对应的网络为基站能够连接的核心网对应的网络的NAS消息；
步骤208，确定所述网络标识指示的网络对应的核心网为所述目标核心网；
步骤203，向所述目标核心网发送所述目标NAS消息。
在本公开的一些实施例中，由于基站预先告知其能够连接的核心网对应的网络的网络信息，使得移动通信终端能够选择对应于基站能够连接的核心网对应的网络的NAS消息，首先就能够避免了基站唯一能够连接的核心网对应的网 络与目标NAS消息对应的网络不一致导致的重新接入流程，加快了接入速度。而同时由于接入请求携带了所述目标NAS消息对应的网络的网络标识，因此基站能够确定所述网络标识指示的网络对应的核心网为所述目标核心网，因此基站确定的目标核心网和目标NAS消息对应的网络相同，保证了移动通信终端能够通过一次接入流程完成到核心网的接入，提高了接入速度。
本公开的一些实施例中，基站能够连接的核心网对应的网络的网络信息可以通过系统信息块SIB或无线资源控制RRC信令携带所述网络信息。
与上述的方法相对应，本公开实施例还提供了用于移动通信终端侧的接入处理方法。
如图6所示，本公开的一些实施例的接入处理方法用于能够连接到第一网络和第二网络的移动通信终端，包括：
步骤301，选择目标非接入层NAS消息，所述目标NAS消息为对应于所述第一网络的第一NAS消息和/或对应于所述第二网络的第二NAS消息；
步骤302，发送携带有目标非接入层NAS消息的接入请求到基站，以通过所述基站发送所述目标NAS消息到一目标核心网，所述目标核心网为对应于所述第一网络的第一核心网和对应于所述第二网络的第二核心网中，所述基站能够连接的核心网；
步骤303，通过所述基站接收目标核心网返回的响应消息。
本公开的一些实施例中，同时能够连接到第一网络和第二网络的移动通信终端发送携带有目标非接入层NAS消息(可以是对应于所述第一网络的第一NAS消息，也可以是对应于所述第二网络的第二NAS消息，还可以同时包括第一NAS消息和第二NAS消息)的接入请求后，基站会向自己所连接的目标核心网发送该目标NAS消息，由目标核心网依据其中目标NAS消息决定是否允许接入。通过上述的流程，能够连接到多种核心网的移动通信终端能通过不同的基站连接到核心网，由核心网决定是否允许接入。
在本公开的一些实施例中，由于所述目标NAS消息可以是第一NAS消息和第二NAS消息中的任意一个或两个，而仅就NAS消息而言，其属于非接入层的消息，对属于接入层的基站而言是不可知的。因此有可能基站确定的目标核心网对应的网络与目标NAS消息对应的网络并不相同，这种情况下，目标核心网 会拒绝接入，为保证移动通信终端能够接入到合适的核心网，本公开的一些实施例的接入处理方法中，移动通信终端接收到该接入拒绝消息后会更换NAS消息重新发起接入流程。
如图7所示，本公开的一些实施例的接入处理方法包括：
步骤301，选择目标非接入层NAS消息，所述目标NAS消息为对应于所述第一网络的第一NAS消息和/或对应于所述第二网络的第二NAS消息；
步骤302，发送携带有目标非接入层NAS消息的接入请求到基站，以通过所述基站发送所述目标NAS消息到一目标核心网，所述目标核心网为对应于所述第一网络的第一核心网和对应于所述第二网络的第二核心网中，所述基站能够连接的核心网；
步骤303，通过所述基站接收目标核心网返回的响应消息。
步骤304，在所述响应消息为指示目标NAS消息对应的网络和所述目标核心网对应的网络不同的接入拒绝消息时，从所述第一NAS消息和第二NAS消息中选择与目标NAS消息不同的NAS消息作为新的目标NAS消息，重新发起接入流程。
本公开的一些实施例的接入处理方法中，当基站确定的目标核心网对应的网络与目标NAS消息对应的网络不相同(或者可称之为NAS不匹配)时，基站会转发目标核心网发送的接入拒绝消息到移动通信终端，而移动通信终端会在接收到接入拒绝消息后选择新的NAS消息重新发起接入流程，实现到目标核心网的接入。
同样，为了解决上述的重新接入流程，本公开的一些实施例分别针对导致重新接入流程的两种情况进行对应改进，描述如下。
本公开的一些实施例的接入处理方法如图8所示，包括：
步骤305，接收所述基站发送的网络信息，所述网络信息指示所述基站能够连接的核心网对应的网络；
步骤306，根据所述网络信息从所述第一NAS消息和第二NAS消息中选择对应的网络为基站能够连接的核心网对应的网络的NAS消息作为所述目标NAS消息；
步骤302，发送携带有目标非接入层NAS消息的接入请求到基站，以通过 所述基站发送所述目标NAS消息到一目标核心网，所述目标核心网为对应于所述第一网络的第一核心网和对应于所述第二网络的第二核心网中，所述基站能够连接的核心网；
步骤303，通过所述基站接收目标核心网返回的响应消息。
在本公开的一些实施例中，由于基站预先告知其能够连接的核心网对应的网络的网络信息，使得移动通信终端能够选择对应于基站能够连接的核心网对应的网络的NAS消息，避免了基站唯一能够连接的核心网对应的网络与目标NAS消息对应的网络不一致导致的重新接入流程，加快了接入速度。
本公开的一些实施例的接入处理方法如图9所示，包括：
步骤305，接收所述基站发送的网络信息，所述网络信息指示所述基站能够连接的核心网对应的网络；
步骤306，根据所述网络信息从所述第一NAS消息和第二NAS消息中选择对应的网络为基站能够连接的核心网对应的网络的NAS消息作为所述目标NAS消息；
步骤307，发送携带有目标非接入层NAS消息和所述目标NAS消息对应的网络的网络标识的接入请求到基站，以通过所述基站发送所述目标NAS消息到一目标核心网，所述目标核心网所述网络标识指示的网络所对应的核心网；
步骤303，通过所述基站接收目标核心网返回的响应消息。
在本公开的一些实施例中，由于基站预先告知其能够连接的核心网对应的网络的网络信息，使得移动通信终端能够选择对应于基站能够连接的核心网对应的网络的NAS消息，首先能够避免了基站唯一能够连接的核心网对应的网络与目标NAS消息对应的网络不一致导致的重新接入流程，加快了接入速度。而同时由于接入请求携带了所述目标NAS消息对应的网络的网络标识，因此基站能够确定所述网络标识指示的网络对应的核心网为所述目标核心网，因此基站确定的目标核心网和目标NAS消息对应的网络相同，保证了移动通信终端能够通过一次接入流程完成到核心网的接入，提高了接入速度。
所述接收所述基站发送的网络信息的步骤中，通过系统信息块SIB或无线资源控制RRC信令接收所述网络信息。
本公开的一些实施例的方法为另一种可以避免重新接入流程的方法，其中， 所述目标NAS消息包括对应于所述第一网络的第一NAS消息和对应于所述第二网络的第二NAS消息，所述接入处理方法如图10所示，包括：
步骤308，选择第一NAS消息和对应于所述第二网络的第二NAS消息作为目标NAS消息；
步骤302，发送携带有目标NAS消息的接入请求到基站，以通过所述基站发送所述目标NAS消息到一目标核心网，所述目标核心网为对应于所述第一网络的第一核心网和对应于所述第二网络的第二核心网中，所述基站能够连接的核心网；
步骤303，通过所述基站接收目标核心网返回的响应消息；
步骤309，根据返回的响应消息的格式确定接入的目标核心网。
对此说明如下。
当目标NAS消息包括两个时，其处理过程如下所述：
移动通信终端发送的接入请求中同时携带第一NAS消息和第二NAS消息；
基站接收到接入请求后随机选择目标核心网；
目标核心网根据自己对应的网络选择第一NAS消息和第二NAS消息中的一个进行处理，并向终端返回所述响应消息；
而终端则根据返回的响应消息的格式确定接入的目标核心网。
对于LTE eNB，则只能将NAS消息转发给EPC，EPC收到接入请求消息，使用第一NAS消息与终端进行安全认证，终端接收NAS消息，发现是EPC格式NAS消息，表示基站将其接入EPC，后续将使用EPC NAS消息进行交互；
而对于eLTE eNB，网络可以选择将终端NAS消息转发给EPC或5G新核心网，EPC或5G新核心网收到接入请求消息，使用各自对应的NAS消息与终端进行安全认证，终端接收NAS消息，发现是EPC格式NAS消息，则表示基站将其接入EPC，后续将使用EPC NAS消息进行交互。而发现是5G cN格式的NAS消息，则表示基站将其接入5G cN，后续将使用5G cN NAS消息进行交互。

为避免从接入的发起，在本公开的一些实施例的基础上，本公开的一些实施例的移动通信终端，还包括：
第四接收模块，用于接收所述基站发送的网络信息，所述网络信息指示所述基站能够连接的核心网对应的网络；
所述第二选择模块具体用于根据所述网络信息从所述第一NAS消息和第二NAS消息中选择对应的网络为基站能够连接的核心网对应的网络的NAS消息作为所述目标NAS消息。
在本公开的一些实施例的基础上，为进一步避免重新接入，本公开的一些实施例的移动通信终端中，所述接入请求还携带有所述目标NAS消息对应的网络的网络标识，以指示所述基站确定所述网络标识指示的网络所对应的核心网为所述目标核心网。
上述的移动通信终端，所述第四接收模块具体用于通过系统信息块SIB或无线资源控制RRC信令接收所述网络信息。
在本公开的一些实施例的基础上，为避免重新接入，本公开的一些实施例的移动通信终端中，所述目标NAS消息为对应于所述第一网络的第一NAS消息和对应于所述第二网络的第二NAS消息，所述移动通信终端还包括：
目标核心网确定模块，用于根据响应消息对应的网络确定所述目标核心网。
以下以第一网络为第四代移动通信网络，第二网络为第四代移动通信网络为例对本公开的一些实施例的方案说明如下。
其中目标NAS消息只有一个时，涉及到如下的几种情况：
1、目标NAS消息为对应于第四代移动通信网络的NAS消息，基站为第四 代移动通信系统中的长期演进基站LTE eNB，目标核心网为对应于第四代移动通信网络的EPC；
2、目标NAS消息为对应于第四代移动通信网络的NAS消息，基站为第五代移动通信系统中的eLTE eNB，目标核心网为对应于第四代移动通信网络的EPC；
3、目标NAS消息为对应于第四代移动通信网络的NAS消息，基站为第五代移动通信系统中的eLTE eNB，目标核心网为对应于第五代移动通信网络的核心网5G CN；
4、目标NAS消息为对应于第五代移动通信网络的NAS消息，基站为第四代移动通信系统中的长期演进基站LTE eNB，目标核心网为对应于第四代移动通信网络的EPC；
5、目标NAS消息为对应于第五代移动通信网络的NAS消息，基站为第五代移动通信系统中的eLTE eNB，目标核心网为对应于第四代移动通信网络的EPC；
6、目标NAS消息为对应于第五代移动通信网络的NAS消息，基站为第五代移动通信系统中的eLTE eNB，目标核心网为对应于第五代移动通信网络的核心网5G CN。
上述的六种情形是目标NAS消息和目标核心网均随机选择的情况下的所有可能的组合。
对于第1、2和6种情形，由于目标NAS消息对应的网络和目标核心网对应的网络相同，因此移动通信终端能够实现最终的接入。
而对于第3、4和5种情形，由于目标NAS消息对应的网络和目标核心网对应的网络不同，因此，移动通信终端第一次接入无法接入，而在更换目标NAS消息后，新的目标NAS消息对应的网络和目标核心网对应的网络相同，因此移动通信终端能够实现最终的接入。
而当基站告知移动通信终端基站能够连接的核心网对应的网络的网络信息，使得移动通信终端在发起接入流程时能够选择对应于所述基站能够连接的核心网对应的的网络的NAS消息，上述的6种情形简化为5种情形，即上述的第4种情形不再存在，而这种情形恰好是需要发起重新接入流程的情况。
上述的网络信息的发送可以结合如图13所示的接入流程来实现，如通过图12中初始接入时基站发送的RRc信令RRc连接建立信令告知终端，也可以通过SIB消息发送。
当基站告知移动通信终端基站能够连接的核心网对应的网络的网络信息，使得移动通信终端在发起接入流程时能够选择所述基站能够连接的核心网对应的网络对应的NAS消息，而移动通信终端在此基础上在接入请求还携带有所述目标NAS消息对应的网络的网络标识时，上述的6种情形简化为5种情形，即上述的3、4和5不再存在，而3、4和5这三种情形恰好是需要发起重新接入流程的情况。
上述的各种情况中，移动通信终端可以直接在无线资源控制RRC连接建立完成消息中携带的附着请求消息中携带NAS消息，而NAS消息的标识也可以在此消息中携带，如图14所示，而无线接入网的网元(如基站)则可以根据NAS消息的标识选择对应的核心网。
而当其中目标NAS消息包括两个时，其处理过程如下所述：
移动通信终端发送的接入请求中同时携带第一NAS消息和第二NAS消息；
基站接收到接入请求后随机选择目标核心网；
目标核心网根据自己对应的网络选择第一NAS消息和第二NAS消息中的一个进行处理，并向终端返回对应格式的NAS消息；
而终端则根据返回NAS消息的格式确定接入的目标核心网。
对于LTE eNB，则只能将NAS消息转发给EPC，EPC收到接入请求消息，使用第一NAS消息与终端进行安全认证，终端接收NAS消息，发现是EPC格式NAS消息，表示基站将其接入EPC，后续将使用EPC NAS消息进行交互；
而对于eLTE eNB，网络可以选择将终端NAS消息转发给EPC或5G新核心网，EPC或5G新核心网收到接入请求消息，使用各自对应的NAS消息与终端进行安全认证，终端接收NAS消息，发现是EPC格式NAS消息，则表示基站将其接入EPC，后续将使用EPC NAS消息进行交互。而发现是5G cN格式的NAS消息，则表示基站将其接入5G cN，后续将使用5G cN NAS消息进行交互。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者 装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。
