Description

一种建立本地网络连接的方法、终端和网络设备
本申请要求了2017年4月19日提交的、申请号为201710257325.1、发明名称为“一种建立本地网络连接的方法、终端和网络设备”的中国申请的优先权，以及2018年2月13日提交的、申请号为201810148817.1、发明名称为“一种建立本地网络连接的方法、终端和网络设备”的中国申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信技术领域，尤其涉及一种建立本地网络连接的方法、终端和网络设备。
背景技术
本地网络是指覆盖特定局部区域的网络，如覆盖企业园区、校园、机场、火车站、大型购物中心或体育馆等场所的网络。用户设备(User Equipment，UE)通过无线接入网访问本地网关，从而直接访问对应的本地网络，避免绕到外部数据网络，从而减少了访问应用的时延和对骨干网络的带宽。如体育馆提供现场VR直播，校园内提供园区通信，访问校园内学习资源，企业园区提供工业控制通信，商场提供本地购物优惠推送和实时位置导航等。
在新一代通信***中，随着移动边缘计算(Mobile Edge Computer，MEC)的兴起，网关位置的下移，为了使用户获得更好的业务体验以及配合内容源的本地化部署，这种本地网络的业务会越来越多。但是由于本地网络只覆盖特定的局部区域，UE并不知道在哪些特定区域覆盖有哪些本地网络，所以需要网络侧下发本地网络的相关信息以通知UE。但是又由于网络侧在向UE下发消息时，用户在空闲状态下，如果UE的位置发生移动，则不能准确地定位UE的当前位置以及当前位置所对应的小区，进而难以准确地将本地网络推送给UE。
目前采用的网络侧下发本地网络相关信息的方法中，UE在接收到网络侧下发的相关信息后，根据这些相关信息以及当前所在的位置确定其是否处于本地网络覆盖的区域。但是，由于当前本地网络覆盖区域的粒度没有定义，可能是Cell粒度也可能是跟踪区(Tracking Area，TA)粒度，并且本地网络区域的位置类型也可能存在多种类型，如3GPP类型或Non-3GPP类型，进而导致UE判断本地网络覆盖区域时需要理解不同的位置粒度和类型，增加了UE处理复杂度。
此外，由于MEC兴起，后续还会存在很多的本地网络，这样UE需要保存大量的本地网络和对应的本地网络覆盖区域信息，但实际UE在判断自己当前位置是否处于本地网络覆盖区域时，只需要当前位置支持的本地网络信息即可，所以UE保存大量本地网络相关信息还会占用大量的存储资源。
发明内容
本申请提供了一种建立本地网络连接的方法、终端和网络设备，以降低UE处理的复杂度。
第一方面，本申请提供了一种建立本地网络连接的方法，所述方法包括如下步骤：终端，例如UE获取基站发送的广播信息；判断该广播信息中是否包括第一本地数据网络LDN列表，其中，所述第一LDN列表由至少一个本地网络标识组成，如果所述广播信息中包括所述第一LDN列表，则根据该第一LDN列表确定一个本地网络标识作为目标本地网络标识，并利用该目标本地网络标识与所述目标本地网络标识对应的本地网络建立会话连接。
本方面提供的方法，UE通过获取基站发送的广播信息，由于该广播信息中包括由至少一个本地网络标识组成LDN列表，使得UE可以基于当前位置获取的这些本地网络标识，确定建立会话连接的目标本地网络标识，并快速地建立会话连接。避免了UE保存大量本地网络覆盖区域的相关信息，节约了UE的存储资源，并且还降低了UE在判断本地网络的覆盖区域时处理的复杂度，提高了连接本地网络的效率。
结合第一方面，在第一方面第一种实现方式中，所述终端在根据第一LDN列表确定目标本地网络标识的过程中具体包括：所述终端根据本地策略在所述第一LDN列表中选择一个本地网络标识，所述终端将所述选择的本地网络标识作为所述目标本地网络标识。其中，所述本地策略包括本地配置LDN的优先级顺序等，本方面不具体限定。
结合第一方面，在第一方面第二种实现方式中，在终端根据第一LDN列表确定目标本地网络标识的过程中具体还包括：所述终端获取来自网络侧，例如控制面节点的第二LDN列表，所述第二LDN列表可以由用户签约的所有本地网络标识组成，或者还可以包括基于该终端所在位置区域的签约的本地网络标识；所述终端根据所述第一LDN列表和所述第二LDN列表确定所述目标本地网络标识。
结合第一方面第二种实现，在第一方面三种实现方式中，在终端根据所述第一LDN列表和第二LDN列表确定所述目标本地网络标识的过程中具体包括：终端比较所述第一LDN列表和所述第二LDN列表是否存在交集，即是否包括至少一个公共的本地网络标识；如果存在交集，则在所述交集中确定一个本地网络标识作为所述目标本地网络标识。进一步地，如果交集中只有一个本地网络标识，则将该本地网络标识作为所述目标本地网络标识；如果交集中包括两个或两个以上的本地网络标识，则根据本地策略手动或者自动选择目标本地网络标识。
本方面的实现方式控制只对签约用户的LDN发起建立会话请求。比如企业园区的LDN只对企业员工开放，外面的人进入企业园区不允许访问。进而避免外部接入后再被拒绝访问导致无效的信令交付流程的增加。
结合第一方面第二种实现，在第一方面四种实现方式中，终端获取来自网络侧的第二LDN列表的过程具体包括：所述终端向所述网络侧发送注册请求消息；所述终端接收所述网络侧反馈的注册应答消息，所述注册应答消息中包括所述第二LDN列表。在本实现方式中网络侧通过注册应答消息携带第二LDN列表，使得终端在注册过程中就获取用户签约的至少一个本地网络标识，避免网络侧单独发送第二LDN列表的流程，节约了信令交互的开 销。
第二方面，本申请还提供了一种建立本地网络连接的装置，该装置可以配置在终端中，所述终端包括用于执行第一方面及第一方面各种实现方式中方法步骤的单元或模块。

具体实施方式
为方便后续描述并清楚地对本申请进行说明，以下首先对本申请可能用到的概念做简要说明：
本申请提供的方法应用于各种网络***，以新一代移动通信技术(例如5G)为例，参见图1，为本申请实施例示出的一种本地网络部署的架构示意图。其中，所述本地网络是指覆盖特定局部区域的网络，例如覆盖园区企业网、校园、机场、火车站、体育馆、大型购物中心等网络。进一步地，所述本地网络覆盖区域可以是跟踪区(tracking area，TA)列表或Cell列表，一个TA列表包含多个跟踪区标识(tracking area identity，TAI)，而一个TA包含多个小区，因此一个TA列表一般比较大，通常包括百多个小区，而一个本地网络覆盖区域一般比较小，一般只覆盖几个小区。
图1所示的网络架构包括：接入网(access network，AN)、控制面(control plane，CP)节点、用户面(uontrol plane，UP)节点、本地用户面节点、校园企业网和报文数据网络。其中，在本申请各个实施例中，至少一个终端，例如UE可以经接入网或者无线接入网(radio access network，RAN)与一个或多个核心网进行通信。
终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或车载的移动装置，它们与无线接入网交换语言和或数据。例如，个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(session initiation protocol，SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)等设备。所述终端也可以称为订户单元(subscriber unit，SU)、订户站(subscriber station，SS)，移动站(mobile station，MS)、远程站(remote station，RS)、接入点(access point，AP)、远端设备(remote terminal，RT)、接入终端(access terminal，AT)、用户终端(user terminal，UT)、用户代理(user agent，UA)、用户设备(user equipment，UE)。
所述接入网或无线接入网可以是基站(NodeB)、增强型基站、或具有调度功能的中继、或具有基站功能的设备等。其中，基站可以是网络***中的演进型基站(evolved NodeB，eNB)，也可以其他***中的基站，本申请实施例并不限定。
本申请提供的技术方案主要针对终端如何获知其当前位置所包括的本地网络，解决UE在感知本地网络覆盖区域时运算量大，占用资源多的问题。
由于本地网络的覆盖区域可能是几个TA或几个小区，所以从规划上基站侧是可以获取当前小区是否支持本地网络，以及支持哪些本地网络的服务，因此可以在小区的无线广播信道中携带支持的本地网络标识，当用户在小区重选时，就可以在广播信道中获取支持的本地网络标识，并建立网络会话连接，下面对本申请提供的一种建立本地网络连接的方法做具体的说明。
实施例一
如图2所示，为本实施例提供的一种建立本地网络连接的方法的信令流程图。以UE、基站和网络设备，如控制面节点为例，对本方法的各个步骤进行说明，具体的，包括如下步骤：
步骤201：基站获取其所在位置区域所支持的第一本地数据网络(local data network，LDN)列表，所述位置区域为该基站位于本地网络的覆盖区域，所述LDN列表由至少一个本地网络标识组成。
所述本地网络标识又可以称为网络标识(data network name，DNN)，是指部署在本地的网络，为了区分正常的网络，所以称为本地网络标识，类似于4G中的接入点名称(access point name，APN)。
当基站处于本地网络的覆盖区域时，获取其所在位置区域所支持的第一LDN列表，该第一LDN列表中包括1个或多个本地网络标识。其中，基站获取所述第一LDN列表的方式可以通过操作管理维护(operations administration maint，OAM)方式自己配置生成，或者，通过与核心网控制面节点之间的信令交方式获取所述第一LDN列表。进一步地，如 果采用信令交互的方式获取，则基站需要向控制面节点发送请求消息，该控制面节点接收请求消息后向基站下发响应消息，所述响应消息中包括该基站所在区域的至少一个本地网络标识。另外，基站还可以通过其他方式获取第一LDN列表，本申请对此不做限制。
另外，本方法还包括UE通过基站注册到网络的步骤，该注册的流程与现有的UE注册流程一致，所以可以参考现有的UE注册流程。本实施例所述的网络可以是控制面节点，还可以是其他网络设备，例如移动管理实体(mobile managenment entity，MME)等。
步骤202：基站广播发送广播信息，所述广播信息中可以携带所述第一LDN列表，还可以不携带该第一LDN列表。例如，当基站所在的位置区域未处于本地网络的覆盖区域时，则广播信息中不包括第一LDN列表。换言之，即可根据基站是否处于本地网络的覆盖区域判断其发送的广播信息是否包括LDN列表。
步骤203：UE获取基站发送的广播信息，并判断该广播信息中是否包括第一LDN列表或者是否包括本地网络标识。
步骤204：如果所述广播信息中包括第一LDN列表，则根据该第一LDN列表确定目标本地网络标识。
具体地，UE根据第一LDN列表确定目标本地网络标识包括：UE根据本地策略在第一LDN列表中选择一个本地网络标识，并将该选择的本地网络标识作为目标本地网络标识。其中，所述本地策略即本地配置，具体可以包括本地配置LDN的优先级策略等。一种UE选择目标本地网络标识的实现方式是，按照本地配置LDN优先级由高到低的顺序，自动选择或者手动选择优先级最高的本地网络标识作为目标本地网络标识。或者，还可以根据用户的当前需求情况手动选择一个DNN作为目标本地网络标识，对此本实施例不做具体限制。
其中，如果UE接收的广播信息中不包括第一LDN列表或者本地网络标识，则UE不触发后续的方法步骤。
可选的，步骤203中还包括UE保存第一LDN列表中的至少一个本地网络标识。
步骤205：UE利用目标本地网络标识建立会话连接。
具体地，UE通过基站与控制面节点建立到本地网络的会话连接，控制面节点再通过控制本地用户面节点实现UE访问本地网络。具体UE与网络侧建立会话连接的过程与现有的会话建立过程相同，不再赘述。
本实施例提供的方法，基站通过无线广播信道广播当前基站所在位置区域所支持的本地网络标识，使得UE可以基于当前位置获取的这些本地网络信息，确定建立会话连接的目标本地网络标识，并快速地建立会话连接。避免了在UE保存大量本地网络覆盖区域的相关信息，节约了UE的存储资源，并且还降低了UE在判断本地网络的覆盖区域时处理的复杂度，提高了连接本地网络的效率。
实施例二
如图3所示，本实施例提供的方法包括如下步骤：
步骤301和步骤302与实施例一中的步骤201和步骤202相同，参见实施例一中的过程描述，不再赘述。
在步骤301与步骤302之间还包括步骤3011：UE注册到网络的步骤。
具体地包括：UE向网络侧控制面节点发送注册请求消息，所述注册请求消息包括初始 注册流程，位置更新的重注册流程。所述初始注册流程即终端开机后的第一次注册，位置更新的重注册流程是指除初始注册流程外的其他注册流程，例如包括注册定时器超时的重注册流程，或由于UE位置变化导致的重注册流程等。
控制面节点根据该注册请求消息生成注册应答消息，并下发给UE，其中，该注册应答消息中包括第二LDN列表，该第二LDN列表由用户签约的所有本地网络标识组成，或者包括基于UE其所在位置区域(TAI列表)下的签约的本地网络标识。
可选的，所述网络侧控制面节点可以从统一数据管理库(united data management，UDM)中获取该用户签约的第二LDN列表，还可以通过其它方式获取第二LDN列表，本实施例对此不做限制。
可选的，UE保存用户签约的第二LDN列表。
步骤303：UE从基站的无线广播信道中获取广播信息，并判断该广播信息中是否包括第一LDN列表。
步骤304：如果包括第一LDN列表，则比较注册应答消息中的第二LDN列表和广播信息中的第一LDN列表是否存在交集，所述交集中包括至少一个相同的本地网络标识。
步骤305：如果存在交集，则在所述交集中确定一个本地网络标识作为所述目标本地网络标识。例如在该交集中，UE根据本地策略手动或自动选择一个本地网络标识作为目标网络标识。
步骤306：UE利用目标本地网络标识建立会话连接，具体建立会话连接的过程与实施例一的步骤205相同。
需要说明的是，本实施例中如果基站下发的广播信息中包括第一LDN列表，但是该第一LDN列表中的所有本地网络标识都与用户签约的本地网络标识不同，即第一LDN列表与第二LDN列表之间不存在交集，则UE不能对该第一LDN列表所对应的本地网络标识发起会话连接。
本实施例提供的方法，网络侧通过注册应答消息向UE下发用户签约的LDN列表，使得UE能够根据其签约的LDN列表和广播信息中携带的LDN列表进行比较，并从交集的本地网络标识集合选择一个发起会话连接，只建立对于用户签约的本地网络的会话连接，从而可以控制只对签约用户的LDN发起建立会话请求。比如企业园区的LDN只对企业员工开放，外面的人进入企业园区不允许访问。如果不根据用户签约的LDN来取交集，则导致外部的人每次进入企业园区都发起会话连接，最后网络侧再拒绝访问，增加无效的信令交付流程。
相对于上面的方法实施例，本申请实施例还提供了相应的终端、网络设备等装置实施例。
参见图4，为本申请实施例提供的一种终端的结构示意图，该终端可以为前述实施例中的UE，也可以设置在其他终端上，用于执行图2或图3所对应的本地网络连接方法。
如图4所示，该终端包括：获取单元401、处理单元402和发送单元403。
其中，获取单元401用于获取基站发送的广播信息，所述广播信息中可以携带第一LDN列表，也可以不携带本地网络标识。
处理单元402用于检测如果广播信息中包括第一LDN列表，则根据所述第一LDN列表 确定目标本地网络标识，其中，所述第一LDN列表由至少一个本地网络标识组成，并利用所述目标本地网络标识与所述目标本地网络标识对应的本地网络建立会话连接。
可选的，在本申请实施例的一种具体实现方式中，处理单元402具体用于根据本地策略在所述第一LDN列表中选择一个本地网络标识，并将所述选择的本地网络标识作为所述目标本地网络标识。
可选的，在本申请实施例的另一种具体实现方式中，获取单元401还用于获取来自网络侧的第二LDN列表，所述第二LDN列表由用户签约的至少一个本地网络标识组成。相应的，处理单元402，具体用于根据所述第一LDN列表和所述第二LDN列表确定所述目标本地网络标识。
可选的，在本申请实施例的另一种具体实现方式中，处理单元402用于根据所述第一LDN列表和所述第二LDN列表确定所述目标本地网络标识，具体用于比较所述第一LDN列表和所述第二LDN列表是否存在交集，如果存在交集，则在所述交集中确定一个本地网络标识作为所述目标本地网络标识。
可选的，在本申请实施例的另一种具体实现方式中，发送单元403用于向所述网络侧发送注册请求消息。相应的，获取单元401具体用于接收所述网络侧反馈的注册应答消息，所述注册应答消息中包括所述第二LDN列表。
可选的，在本申请实施例的另一种具体实现方式中，所述终端还可以包括存储单元，用于存储第一LDN列表、第二LDN列表等信息。
与本实施例提供的终端相对应，本实施例还提供了一种网络设备。该网络设备可以为前述实施例中的基站，也可以是其它网络设备，例如RAN等，用于执行图2或图3所对应的本地网络连接方法。
参见图5，为所述网络设备的一个结构示意图。该网络设备包括获取单元501和发送单元502，此外，还可以包括处理单元、存储单元等。
其中，获取单元501用于获取其所在位置区域所支持的第一LDN列表，所述位置区域为所述设备位于本地网络的覆盖区域，所述第一LDN列表由至少一个本地网络标识组成；发送单元502用于将所述第一LDN列表通过广播信息携带的方式发送。
可选的，在本申请实施例的一种具体实现方式中，获取单元501具体用于通过OAM配置所述第一LDN列表，或者通过与网络侧之间的信令交互方式获取所述第一LDN列表；还可以通过处理器配置生成第一LDN列表，本实施例并不限制。
本实施例提供的终端和网络设备，在实现上述方法实施例的建立本地网络连接的过程中，网络设备通过无线广播信道广播其所在位置区域所支持的本地网络标识，使得接收端终端UE可以基于当前位置获取的这些本地网络信息，确定建立会话连接的目标本地网络标识，并快速地建立会话连接。避免了在UE保存大量本地网络覆盖区域的相关信息，节约了UE的存储资源，并且还降低了UE在判断本地网络的覆盖区域时处理的复杂度，提高了连接本地网络的效率。

其中，基站为UE当前所处位置区域对应的基站。所述接入请求包括附着请求，位置更新请求(如，TAU Request)或者注册请求等，其中注册请求包括初始注册导致的注册请求，或者移动注册更新(即，位置区域发生变化)导致的注册请求
其中，所述接入指示信息用于指示UE是否允许接入本地网络或者用于指示请求方UE是否想要获取本地网络服务。具体地，可以包括以下各种形式来指示：
一种可能的方式是，所述接入指示信息中携带有第一指示符号或字段，用于指示所述UE允许接入到本地网络。例如所述第一指示符号或字段为“1”，如果接入指示信息中携带有“1”的指示符号，则表示该UE允许接入到本地网络。
另一种可能的方式是，所述接入指示信息中还可以携带有第二指示符号或字段，用于指示UE不允许/禁止接入到本地网络。例如所述第二指示符号或字段为“0”，如果接入指示信息中携带有“0”的指示符号，则表示该UE不允许接入到本地网络。
或者，通过接入指示信息中是否携带有特定的指示符号或字段来指示UE是否允许接入本地网络，例如，如果所述接入指示信息中携带有第一指示字段，则指示该UE允许接入；如果未携带第一指示字段，则指示该UE不允许接入本地网络。
可以理解地，所述本地网络接入指示信息可以指示用户的意愿。实际应用中，可以在UE中设置一个“同意”和/或“拒绝”选项，用于指示用户是否同意所使用的用户设备接入本地网络。当检测到对“同意”选项的触发操作时，即可在接入请求中携带指示该UE允许接入本地网络的本地网络接入指示信息，当检测到对“拒绝”选项的触发操作时，即可在接入请求中携带指示该UE不允许接入本地网络的本地网络接入指示信息。
此外，还可以通过在所述接入指示信息中设置其它符号、字段或信息来指示UE是否允许接入到本地网络，本实施例对此不予限制。

本实施例提供的方法，增加了终端用户设备意愿的灵活性，用户设备可以自主选择接受控制面节点发送的本地网络信息，即在用户不愿意发起本地网络服务时，避免控制面节点发送本地网络信息，达到节约信令交互的目的，同时可以节约终端设备的内存。
方案二
本实施例提供了一种本地网络信息发送方法，该方法中的控制面设备根据本地网络的标识信息和UE当前所在的位置区域标识来确定所述UE的本地网络信息。具体方法包括以下步骤：
如图9所示，步骤901：UE经由基站向控制面节点发送接入请求，接入请求中携带了一个或多个本地网络的标识信息。
其中，本地网络的标识信息用于唯一的标识一个本地网络，例如可以是本地网络的名称。此外，该本地网络的标识信息也可用于指示所述UE期望获取该本地网络的对应的服务范围信息，或者该UE后续期望接入的本地网络。
步骤902：基站接收到用户设备发送的接入请求时，确定该UE当前所处的位置区域标识。
所述UE当前位置区域标识与方案一中的位置区域标识相同，参见方案一中的描述本实施例不再赘述。
步骤903：基站向控制面节点发送所述接入请求，或者发送接入请求和所述UE当前所处的位置区域标识。
所述接入请求中的至少一个本地网络的标识信息还可以通过第一信息携带。
步骤904：控制面节点接收基站发送的接入请求和UE当前所处的位置区域标识，根据所述接入请求中携带的本地网络的标识信息确定需要UE可用的本地网络信息，或者，根据控制面节点获取的本地网络信息、以及所述本地网络的标识信息和UE当前所处的位置区域标识确定UE可用的本地网络信息。其中，所述本地网络信息可以是仅包括本地网络的服务范围信息，也可以是包括本地网络标识和对应的服务范围信息。
具体地，第一种实现方式，控制面节点根据本地网络的标识信息确定UE可用的本地网络信息，包括：
控制面节点从存储的本地网络信息中查找是否有无包含与所述本地网络标识对应的服务范围信息，如果包括，则将该本地网络标识对应的服务范围信息作为所述UE可用的本地网络信息。
可选的，第二种实现方式，控制面节点根据获取的本地网络信息、以及本地网络的标识信息和UE当前所处的位置区域标识确定UE可用的本地网络信息，包括：
方式一：所述控制面节点从配置的或存储的本地网络信息中查找是否包含所述本地网络的标识信息对应的本地网络；
如果包含，则进一步判断该本地网络对应的服务范围信息中是否包括UE当前所处的位置区域标识，如果包括，则确定所述本地网络对应的服务范围信息为所述UE可用的本地网络信息；如果不包括，则确定控制面节点的本地网络信息中没有UE所请求的本地网络信息。
其中，所述不包括可以理解为，判断本地网络信息中是否包含本地网络的标识信息对应的本地网络，和，判断本地网络对应的服务范围信息中是否包括UE当前所处的位置区域标识，两个条件中至少有一个条件不满足。
方式二：该控制面节点可以从配置的或存储的本地网络信息中查找是否有包括所述UE的位置区域标识对应的本地网络信息；
