相关申请的交叉引用
本申请主张在2017年9月29日在中国提交的中国专利申请号No.201710906531.0的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，特别是指一种本地数据网的发现、配置方法、终端、核心网设备及基站。
背景技术
近年来，随着移动互联网业务的快速发展，人们越来越多地使用移动终端进行网络浏览、电影下载和在线视频聊天等宽带业务，同时虚拟现实、增强现实等新兴业务的不断涌现，对移动网络的数据传输速率和端到端时延都提出了更高的要求，给移动通信网络带来了极大的挑战：当前移动网络如4G，业务数据的传输需要通过传输网路由器和核心网网关的多跳转发，端到端时延较长；互联网业务的爆发性增长使以集中化为特征的核心网和回传网络面临巨大的压力，数据的路由和转发可能成为提升网络性能和用户体验的瓶颈。
相关技术中提出了在靠近无线网网络侧部署边缘计算节点，比如本地转发/缓存模块，将业务内容提供节点更加靠近用户，一方面可以缓解核心网回传压力，降低业务端到端的时延，提升用户体验；另一方面可以让运营商开辟新的商业模式，比如通过互联网向用户提供各种应用服务(Over The Top，OTT)内容提供商服务器部署更靠近用户，以提升用户访问体验，从而向OTT内容提供商收取费用。
3GPP在4G标准中引入了相关标准化方案，包括本地IP存取(Local IP Access，LIPA)/选择IP流量卸除(Selected IP Traffic Offload，SIPTO)以及4G演进中进一步提出的控制面和转发面分离(Control Plane and User Plane Seperation，CUPS)方案。
相关技术中方案有如下问题：
LIPA/SIPTO：本地业务的分流需要通过建立端到端PDN(公用数据网)的连接实现，且该PDN连接的建立需要通过配置APN(接入点名称)实现，需要终端用户手动操作，且受限于终端操作系统。此外，APN能够支持分流的数量和灵活度有限。
CPUS：标准化方案同样依赖与APN配置，本地分流的数据仍需要通过额外网关，会带来额外时延和复杂度。
针对4G支持本地网技术方案的缺陷，目前正在3GPP开展的5G端到端网络架构标准化在设计初始便将边缘计算作为功能和需求考虑，支持业务向本地数据网的分流，且制定了三种方案分别为：基于数据网络接入点(data network name，DNN)的多协议数据单元(Protocol Data Unit，PDU)会话本地网方案、基于上行分流器(UL classifier)的本地网方案、基于多链路(Multi-homing)的本地网方案。
无论上述哪种方案，均需要终端感知当前是否有本地数据网可以使用以及该本地数据网的范围多大，相关技术中方案是基于跟踪区定义本地数据网的范围，但考虑到跟踪区范围配置不够灵活且往往范围太大，未来本地数据网的应用模式更多是很小范围的，故相关技术中方案无法适用。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
如图1所示，本公开实施例提供一种本地数据网的发现方法，应用于终端，所述发现方法包括：
步骤11，接收核心网络发送的所述核心网注册区域内支持的本地数据网的信息。
本步骤中，核心网维护支持本地数据网的信息，虽然本地数据网可以部署在基站上或者基站附近，但是多个本地数据网的使用策略仍需要由核心网掌控。
步骤12，接收基站发送的与所述基站或小区绑定的本地数据网的信息。
本步骤中，与所述基站或小区绑定的本地数据网的信息可以通过基站的系统信息携带，即服务节点周期性或非周期性广播系统信息，该系统信息中携带与所述基站或小区绑定的本地数据网的信息；还可以通过专用信令向终端发送，即专用信令中携带与所述基站或小区绑定的本地数据网的信息。
步骤13，根据所述核心网注册区域内支持的本地数据网的信息和与所述基站或小区绑定的本地数据网的信息，确定是否存在终端当前能够使用的本地数据网。
本步骤中，终端根据所述核心网注册区域内支持的本地数据网的信息和与所述基站或小区绑定的本地数据网的信息，能够感知附近可用的本地数据网。
进一步的，为了实现更细粒度的本地网管理，本公开的上述实施例中所述核心网注册区域内支持的本地数据网是基于小区粒度的，或者所述核心网注册区域内支持的本地数据网是基于基站粒度。
较佳的，若核心网注册区域内支持的本地数据网是基于基站粒度的，即只有接入或驻留在与本地数据网对应的基站的终端才能够利用该本地数据网进行分流；例如，支持本地数据网A与基站B绑定或对应，则当终端接入该基站B或终端驻留在该基站B时，若终端需发起针对本地数据网的业务，此时终端可以激活该本地数据网A，并通过该本地数据网A的本地网通道传输。而当终端接入基站C或者终端驻留在基站C时，即使基站C的覆盖范围内包 含本地数据网点A，终端发起的业务也不能通过本地数据网A的本地网通道传输。
进一步的，若核心网注册区域内支持的本地数据网是基于小区粒度的，即只有接入或驻留在与本地数据网对应的小区的终端才能够从该本地数据网的本地数据网进行分流；例如，支持本地数据网D与小区E绑定，则当终端接入该小区E或终端驻留在该小区E时，若终端需发起针对本地数据网的业务，此时终端可以激活该本地数据网D，并通过该网络节点D的本地网通道传输。而当终端接入小区F或者终端驻留在小区F时，即使小区F的覆盖范围内包含本地数据网D，终端发起的业务也不能通过本地数据网D的本地网通道传输。
需要说明的是，若核心网注册区域内支持的本地数据网的基于小区粒度或者基站粒度的，此时可通过基站ID或小区ID表示，在此不作详细描述。本公开的上述实施例中，为了更清晰的展示基站或小区与本地数据网的对应关系，上述核心网注册区域内支持的本地数据网的信息可以通过列表的形式呈现。且进一步需要说明的是，本公开的上述实施例所述的绑定只是为了指示基站/小区与支持本地数据网的对应关系，其并没有实际绑定的含义；核心网仅配置基站/小区与支持本地数据网的网络节点之间的对应关系(或映射关系)，或者用其他方式指示其绑定关系，均适用于本申请，在此不一一枚举。
服务基站可以发送与其包含的多个小区分别绑定的本地数据网的信息，也可以发送与该基站绑定的本地数据网的信息(此时表明接入该基站下的任意一个小区的终端均可以使用其基站对应的本地数据网进行本地数据分流)。而服务小区一般仅发送与本小区帮的能够的本地数据网的信息，即接入本小区的终端才能够利用与本小区绑定的本地数据网进行本地数据分流。
进一步的，本公开的上述实施例中步骤13包括：
若存在至少一个目标本地数据网，所述目标本地数据网与终端的服务基站或服务小区绑定，且所述目标本地数据网是所述核心网注册区域内支持的本地数据网，确定存在终端当前能够使用的本地数据网；否则，确定不存在终端当前能够使用的本地数据网。
例如，存在一本地数据网P，该本地数据网P与终端的服务基站绑定(即 能够从终端的服务基站发送的与终端绑定的本地数据网的信息中得到本地数据网P)；且该本地数据网P为核心网注册区域内支持的本地数据网；则该本地数据网P为终端当前能够使用的本地数据网。
需要说明的是，目标本地数据网的数量可以为1个、2个、3个或者更多，核心网或者基站可以为这些目标本地数据网设置优先级，终端选择优先级高的进行数据传输；或者核心网或基站通过其他信令告知终端其选择的目标本地数据网，在此不作具体限定。
进一步的，本公开的上述实施例中，若存在终端当前能够使用的本地数据网，所述方法还包括：
若终端需要发送针对所述目标网络节点的业务，终端触发针对所述目标网络节点的分组数据单元会话的建立；
所述分组数据单元会话建立完成之后，所述终端与所述目标网络节点之间进行业务传输。
进一步的，本公开的上述实施例中步骤11包括：
步骤111，向核心网发送注册请求消息；
步骤112，接收核心网反馈的注册接受消息，所述注册接受消息中携带所述核心网注册区域内支持的本地数据网的信息。
本公开的具体实施例中，终端开机发起注册流程，发起注册请求，则在核心网的AMF(认证管理功能实体)发往终端的注册接受消息中携带所述核心网注册区域内支持的本地数据网的信息。该核心网注册区域内支持的本地数据网的信息可以是基于终端的签约等信息制定的，在此不作具体限定。
进一步的，若所述核心网注册区域内支持的本地数据网的信息发生更新，所述发现方法还包括：
所述终端在配置更新过程中或者在跟踪区更新过程中获取更新后的所述本地数据网的信息。
综上，本公开的上述实施例提供的本地数据网的发现方法中，核心网向终端发送核心网注册区域内支持本地数据网的信息，基站向终端发送与所述基站或小区绑定的本地数据网的信息，终端则根据所述核心网注册区域内支持的本地数据网的信息和与所述基站或小区绑定的本地数据网的信息，确定 是否存在终端当前能够使用的本地数据网，该方案能够辅助终端感知附近可用的支持本地数据网的网络节点，并实现更细粒度的本地网管理，提升用户体验。
