Description

无线通信接入方法、通信装置、无线终端及系统 技术领域
本发明实施例涉及通信技术，尤其涉及一种无线通信接入方法、通信装置、无线终端及系统。
背景技术
随着移动通信技术的不断发展，第五代无线通信系统(5G，the 5th Generation of wireless communication system)将支持接入多种类型的终端设备，包括人与人通信的设备(例如智能手机)、机器类型设备、汽车、无人机、机器人等等。不同终端具有不同的业务类型需求，同一终端在不同场景下也有不同的业务类型需求，例如智能手机在娱乐环境下会发起语音/视频通话与数据业务，在车载环境下又会发起导航与自动驾驶控制业务。不同的设备类型或业务类型对移动通信网络有不同的通信业务服务质量(QoS，Quality of Service)要求，如语音/视频通话与数据业务要求高速率、较低时延的QoS，而导航与自动驾驶控制业务则要求较高速率、超低时延的QoS。
同时，5G系统还将支持多种类型的接入网络，例如第三代合作伙伴计划(3GPP，3rd Generation Partnership Project)网络、非第三代合作伙伴计划(如蓝牙、WLAN等)网络等。接入网络的接入节点有多种，例如基站、支持设备间通信(D2D，Device to Device)的终端、无线访问接入点(AP，Wireless Access Point)等。不同接入网络的接入节点所支持的通信类型不同，如超宽带无线通信(Ultra Broadband Wireless Communication，或称增强的移动宽带通信enhanced Mobile Broadband)、机器类型设备通信(MTC，Machine Type Communications))等。因此，不同类型的接入网络所提供的QoS不同，同一接入网络的不同接入节点所提供的QoS也不同。
在现有无线通信系统中，终端根据网络的信号状况，如信号功率、信号质量等，来选择接入网络的服务小区，但终端选择的服务小区可能由于不支持特定的通信类型，而无法支持终端的业务需求。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
首先，对以下各实施例中的用词和术语进行解释:
当本发明实施例中提及“第一”、“第二”等序数词时，除非根据上下文其确实表达顺序之意，应当理解为仅仅是起区分之用。
本发明实施例提供的技术方案应用于无线终端更换接入节点接入网络的场景。以无线终端发起注册请求为例：核心网设备收到接入节点发送的无线终端的注册请求后，根据无线终端的设备类型和/或业务类型，以及该无线终端本地可接入的接入节点的设备能力，确定设备能力能够支持该无线终端的设备类型和/或业务类型的接入节点作为目标接入节点。如果确定的目标接入节点和原接入节点为同一接入节点，则由原接入节点继续完成该无线终端的注册事务，如果确定的目标节点和原接入节点不是同一接入节点，则指示由目标接入节点代替原接入节点完成该无线终端的注册事务，即该无线终端由原接入节点更换至目标接入节点，进行注册。
在实际应用中，无线终端可以是手机、平板电脑、智能家居、远程医疗设备、无人驾驶汽车等能够接入无线通信网络的多种通信设备。
在本发明实施例中提及“无线通信网络”时，是指可被与其他公共网或专用网互连互通，以使无线终端传送和接收信息的广域通信网络。该无线通信网络中的通信主体包括无线终端、一个或多个接入节点、以及与接入节点通信连接的核心网设备。
在本发明实施例中提及“接入节点”时，是指在无线通信网络中，为无线终端提供无线通信链路的网络接入设备，具体包括无线通信网络的接入网设备、支持设备到设备(Device-to-Device，简称D2D)通信的无线终端设备。接入节点可以是一个单独的物理设备，也可以是安装在某一物理设备上的软件，例如基站、支持D2D功能的手机等。
在本发明实施例中提及“第一接入节点”时，是指接收无线终端发送的第一连接请求的接入节点，即无线终端在首次发起连接请求时，所接入的接入节点。
在本发明实施例中提及“可接入的接入节点”时，是指无线终端在本地可连接的接入节点。
在本发明实施例中提及“目标接入节点”时，是指无线终端本地可接入的，设备能力能够支持无线终端的设备类型和/或业务类型的接入节点。

在本发明实施例中提及“设备类型”时，是指根据无线终端的主要功能预先设置的属性值。5G系统中的通信设备将不仅仅局限于智能手机、平板电脑等无线终端，智能家居、穿戴设备、无人驾驶车辆、远程医疗机器等各种具备无线通信功能的通信设备均将接入至5G系统的无线通信网络。不同的通信设备具有不同的设备类型，不同的设备类型对无线通信网络的服务质量要求不同，例如工厂中通过安装在工厂内部或附近的基站进行相互通信的机器，其设备类型为机器类型设备(Machine Type Device)，无人驾驶车辆的设备类型为车载类型设备(Vehicle Type Device)。其中，一个无线终端可以对应一个设备类型，也可以同时对应多个设备类型，例如手机可包括通信设备、车载类型设备等多种设备类型。
在本发明实施例中提及“业务类型”时，是指根据无线终端发起业务所要求的无线网络通信的服务质量，而预先设置的属性值。例如无人驾驶车辆发起无人驾驶业务时，无人驾驶业务对无线网络通信具有超低时延要求，因此预设无人驾驶业务的业务类型为超低延迟业务(ultra-low latency service)；再如，工厂中的机器通过工厂内部或附近的基站进行相互通信，预设此类业务的业务类型为本地机器类型通信业务(Local Machine Type Communication service)等。一个无线终端可以对应一个业务类型，也可以对应多个业务类型，如手机在发起语音通信业务时，其业务类型为语音通话业务(Voice Communication service)，如手机在发起车载导航业务时，其业务类型为超低延迟业务。

下面以具体的实施例对本发明的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
实施例1
图1为本发明实施例1中一种无线通信接入方法的流程示意图。如图1所示，本实施例的无线通信接入方法的执行主体为核心网设备，该方法包括：
S101：接收第一接入节点发送的第一连接请求；
S103：根据所述无线终端的设备类型和/或业务类型，以及所述无线终端可接入的接入节点的设备能力，确定目标接入节点；
S105：指示由所述目标接入节点将所述无线终端接入网络。
具体地，无线终端发送第一连接请求至第一接入节点，第一接入节点发送该第一连接请求至核心网设备。其中第一连接请求中携带无线终端的设备类型和/或业务类型(即设备类型和业务类型中的至少一个)。
可选地，核心网设备接收第一接入节点发送的第一连接请求之后，核心网设备对该无线终端进行鉴权。具体地，第一连接请求中还可以携带无 线终端的标识，核心网设备通过无线终端的标识，查询该无线终端所对应的用户签约数据，根据签约数据确定该无线终端支持的鉴权方式，然后对该无线终端进行鉴权。或者，第一连接请求中携带无线终端的标识、无线终端的设备类型和/或业务类型，核心网设备根据该无线终端的设备类型和/或业务类型确定该无线终端支持的鉴权方式，然后对该无线终端进行鉴权。或者，第一连接请求中还携带该无线终端支持的鉴权方式和鉴权参数，核心网设备根据该终端支持的鉴权方式和鉴权参数对该无线终端进行鉴权。鉴权通过后，核心网设备根据签约数据中该无线终端支持的安全信息，对该无线终端进行加密和/或完整性保护，建立安全连接。
核心网设备收到第一连接请求后，确定该无线终端可接入的接入节点，无线终端可接入的接入节点至少有一个，即第一接入节点；可接入的接入节点也可以有多个，即第一接入节点和一个或多个第二接入节点。具体地，第一连接请求还携带所述无线终端的位置信息，核心网设备根据无线终端的位置信息，确定该无线终端在本地可接入的接入节点，然后获取无线终端可接入的接入节点的设备能力。当然，核心网设备还可以通过其他方式确定无线终端可接入的接入节点，在此不作具体限定。
可选地，核心网设备确定本地可接入的接入节点后，获取接入节点的设备能力的方法有多种，在此不作具体限定。例如核心网设备从接入节点发送给核心网设备的消息中携带的接入节点设备能力信息中获取；或从本地存储的接入节点设备能力信息中查询获取；或从核心网云平台存储的接入节点设备能力信息中获取；或从其他核心网设备(如网络配置管理设备)存储的接入节点设备能力信息中获取。
接入节点的设备能力是指接入节点或接入节点所服务的接入网络支持的具有不同服务质量的通信类型，进一步地，接入节点的设备能力还可以包括接入节点支持的核心网管理能力，如会话管理功能(Session Management)。当接入节点的设备能力包括核心网管理能力时，核心网设备可根据接入节点所支持的核心网管理能力，确定下发至接入节点的信令。例如：若接入节点支持会话管理功能，则核心网设备发给接入节点的信令中不仅可以携带无线接入承载相关的信息，还可以携带供接入节点解析的会话管理相关的信息，例如PDN Connection Context(分组数据网络连 接上下文)；若接入节点支持车载通信，则核心网设备发给接入节点的信令中可以携带供接入节点解析的车载通信会话相关信息。
一个接入节点可支持一种设备能力，也可以支持多种设备能力，具体表现形式有多种，例如，接入节点A的设备能力情况如下表所示，其中Bit N代表一种设备能力，1代表support(支持)，0代表not support(不支持)：
Bit6 Bit5 Bit4 Bit3 Bit2 Bit1
1 0 0 1 1 0
Bit 6:Session Management(会话管理),1-support(支持)；
Bit 5:Ultra Reliable Communication(超可靠通信),0-not support；
Bit 4:Ultra Broadband Communication(超宽带通信),0-not support；
Bit 3:V2X Communication(车辆通信),1-support；
Bit 2:D2D Communication(设备间通信),1-support；
Bit 1:xx Communication(xx通信),0-not support；
根据上表可知，接入节点A的设备能力包括会话管理、车辆通信和设备间通信。
核心网设备获取接入节点的设备能力后，根据无线终端的设备类型和/或业务类型，以及所述无线终端可接入的接入节点的设备能力，在无线终端可接入的接入节点中，确定设备能力能够支持该无线终端的设备类型和/或业务类型的接入节点作为目标接入节点。核心网设备指示由目标接入节点将该无线终端接入无线通信网络。
进一步地，核心网设备确定目标接入节点的方式有三种，择一使用：
1、根据无线终端的设备类型和无线终端可接入的接入节点的设备能力，在无线终端可接入的接入节点中，确定设备能力能够支持该无线终端的设备类型的接入节点作为目标接入节点。
例如：无线终端UE1的设备类型为车载类型设备(Vehicle Type Device)，UE1可接入的接入节点有两个，分别为基站A和基站B，其中基站A的设备能力为超宽带通信(Ultra Broadband Communication)，基站B的设备能力为车辆通信(V2X Communication)，其中基站B的设备能力能够支 持UE1的设备类型，由此，核心网设备确定基站B作为UE1的目标接入节点。
2、根据无线终端的业务类型和无线终端可接入的接入节点的设备能力，在无线终端可接入的接入节点中，确定设备能力能够支持该无线终端的业务类型的接入节点作为目标接入节点。
例如：无线终端UE1发起导航业务，导航业务所对应的业务类型为超低延迟业务(ultra-low latency service)，该无线终端UE1可接入的接入节点有两个，分别为基站C和支持设备到设备(Device-to-Device，简称D2D)通信的无线终端设备UE2，基站C的设备能力为超低延迟通信(ultra-low latency Communication)，UE2的设备能力为超可靠通信(Ultra Reliable Communication)，其中基站C的设备能力能够支持UE1的设备类型，由此，核心网设备确定基站C作为UE1的目标接入节点。
3、根据无线终端的设备类型和业务类型，以及无线终端可接入的接入节点的设备能力，在无线终端可接入的接入节点中，确定设备能力能够支持该无线终端的设备类型和业务类型的接入节点作为目标接入节点。
例如：无线终端UE1的设备类型为机器类型设备(Machine Type Device)，业务类型为本地机器类型通信(Local Machine Type Communication)，UE1可接入的接入节点为基站D，基站D的设备能力为本地机器类型通信(Local Machine Type Communication)，基站D的设备能力能够支持UE1的设备类型和业务类型，由此，核心网设备确定基站D作为UE1的目标接入节点。
确定接入节点的设备能力是否支持无线终端的设备类型和/或业务类型的方法有多种，例如在核心网设备中预设无线终端的设备类型和/或业务类型与接入节点的设备能力之间的关系映射表，根据无线终端的设备类型和/或业务类型、接入节点的设备能力以及该关系映射表，确定该接入节点的设备能力是否支持该无线终端的设备类型和/或业务类型；或者，根据无线终端的设备类型和/或业务类型所要求的服务质量和接入节点的设备能力所支持的服务质量进行匹配，确定该接入节点的设备能力是否支持该无线终端的设备类型和/或业务类型，本发明实施例中并不限制具体的确定方法。
需要说明的是，当无线终端可接入的接入节点有多个时，即包括第一接入节点和一个或多个第二接入节点时，核心网设备可以先确定第一接入 节点的设备能力是否支持无线终端的设备类型和/或业务类型，如果第一接入节点的设备能力支持该无线终端的设备类型和/或业务类型，则直接确定第一接入节点为目标接入节点，不再对第二接入节点进行确定。如果第一接入节点的设备能力不支持该无线终端的设备类型和/或业务类型，再确定第二接入节点的设备能力是否支持该无线终端的设备类型和/或业务类型。
或者，核心网设备确定所有无线终端可接入的接入节点是否支持无线终端的设备类型和/或业务类型，如果存在一个设备能力支持无线终端的设备类型和/或业务类型的接入节点，则确定该接入节点作为目标接入节点。如果存在多个设备能力支持无线终端的设备类型和/或业务类型的接入节点，则随机选择一个接入节点作为目标接入节点，或者选择无线终端接入时信号强度或信号质量(信号质量为信号强度与噪声强度的比值)最优的接入节点作为目标接入节点，或者选择能够为无线终端提供最佳QoS的接入节点作为目标接入节点，或者直接选择第一接入节点作为目标接入节点(第一接入节点的设备能力支持无线终端的设备类型和/或业务类型)。具体确定方法在此不做限定。
在本发明实施例中，核心网设备根据无线终端的设备类型和/或业务类型、以及无线终端可接入的接入节点的设备能力，确定设备能力能够支持无线终端的设备类型和/或业务类型的接入节点作为目标接入节点，并指示目标接入节点将该无线终端接入网络。将不同设备类型或业务类型的终端，接入符合其业务需求的接入节点，实现了为无线终端提供更优质的通信质量。
图2为本发明实施例1中另一种无线通信接入方法的流程示意图。如图2所示，本实施例的无线通信接入方法的执行主体为核心网设备，该方法包括：
S201：接收第一接入节点发送的第一连接请求；
S203：根据所述无线终端的设备类型和/或业务类型，以及所述第一接入节点的设备能力，确定所述第一接入节点的设备能力是否支持所述无线终端的设备类型和/或业务类型；
如果所述第一接入节点的设备能力支持所述无线终端的设备类型和/或业务类型，则进入步骤S205；如果所述第一接入节点的设备能力不支持所述无线终端的设备类型和/或业务类型，则进入步骤S207；
S205：将所述第一接入节点作为所述目标接入节点；进入步骤S217；
S207：根据所述无线终端的设备类型和/或业务类型，以及所述第二接入节点的设备能力，确定所述第二接入节点的设备能力是否支持所述无线终端的设备类型和/或业务类型；
如果所述第二接入节点的设备能力支持所述无线终端的设备类型和/或业务类型，则进入步骤S209；如果所述第二接入节点不支持所述无线终端的设备类型和/或业务类型，则进入步骤S211；
S209：将所述第二接入节点作为所述目标接入节点；进入步骤S217；
S211：将所述无线终端的设备类型和/或业务类型所要求的服务质量，与所述无线终端可接入的接入节点所提供的服务质量进行匹配，计算服务质量匹配程度；
S213：确定所述服务质量匹配程度最高的接入节点作为次目标接入节点；进入步骤S215；
S215：指示由所述次目标接入节点将所述无线终端接入网络；
S217：指示由所述目标接入节点将所述无线终端接入网络。
具体地，无线终端发送第一连接请求至第一接入节点，第一连接请求中携带无线终端的设备类型和/或业务类型。第一接入节点转发该第一连接请求至核心网设备，其中，第一接入节点可以将第一接入节点的设备能力携带于该第一连接请求中发送至核心网设备。
一方面，核心网设备接收第一接入节点发送的第一连接请求之后，核心网设备对该无线终端进行鉴权。具体地，第一连接请求中可以携带无线终端的标识，核心网设备通过无线终端的标识，查询该无线终端所对应的用户签约数据，根据签约数据确定该无线终端支持的鉴权方式，然后对该无线终端进行鉴权。或者，第一连接请求中携带无线终端的设备类型和/或业务类型，根据该无线终端的设备类型和/或业务类型确定该无线终端支持的鉴权方式，然后对该无线终端进行鉴权。或者，第一连接请求中携带该无线终端支持的鉴权方式和鉴权参数，核心网设备根据该终端支持的鉴权方式和鉴权参数对该无线终端进行鉴权。鉴权通过后，对该无线终端进行加密和/或完整性保护，建立安全连接。
另一方面，在接收第一接入节点发送的第一连接请求之后，核心网设 备获取第一接入节点的设备能力，具体的获取方法有多种，例如：核心网设备根据第一接入节点的标识，在核心网服务器中预存储的接入节点设备能力中查询第一接入节点的设备能力；或者，第一接入节点在转发无线终端发送的第一连接请求时，将第一接入节点的设备能力携带于第一连接请求中发送至核心网设备，本实施例并不限定核心网设备获取第一接入节点的设备能力的具体方式。
进一步地，接入节点的设备能力除包括接入节点支持的具有不同服务质量的通信类型外，还包括设备能力支持的核心网管理能力，如会话管理功能(Session Management)。当接入节点的设备能力包括核心网管理能力时，核心网设备可根据接入节点所支持的核心网管理能力，确定下发至接入节点的信令。例如：若接入节点支持会话管理功能，则核心网设备发给接入节点的信令中不仅可以携带无线连接承载相关的信息，还可以携带供接入节点解析的会话管理相关的信息，例如PDN Connection Context(分组数据网络连接上下文)；若接入节点支持车载通信，则核心网设备发给接入节点的信令中可以携带供接入节点解析的车载通信会话相关信息。
核心网设备根据无线终端的设备类型和/或业务类型，以及第一接入节点的设备能力，确定第一接入节点是否支持无线终端的设备类型和/或业务类型。具体的确定方式有三种，即根据无线终端的设备类型和第一接入节点的设备能力，确定第一接入节点是否支持无线终端的设备类型；或根据无线终端的业务类型和第一接入节点的设备能力，确定第一接入节点是否支持无线终端的业务类型；或根据无线终端的设备类型和业务类型，以及第一接入节点的设备能力，确定第一接入节点是否支持无线终端的设备类型和业务类型；具体方式与上述实施例中的确定方式相似，在此不再赘述。
如果第一接入节点的设备能力支持无线终端的设备类型和/或业务类型，则确定第一接入节点作为目标接入节点，即由第一接入节点继续接入无线终端，无线终端无需更换接入节点。
如果第一接入节点的设备能力不支持无线终端的设备类型和/或业务类型，则进一步确定该无线终端可接入的除第一接入节点以外的接入节点是否支持该无线终端的设备类型和/或业务类型，即确定第二接入节点是否支持该无线终端的设备类型和/或业务类型。
进一步地，核心网设备预先获取第二接入节点的设备能力，具体获取第二接入节点的设备能力的方式为：第一连接请求中还携带所述无线终端的位置信息，核心网设备根据无线终端的位置信息确定该无线终端还有哪些可接入的其他接入节点，即确定第二接入节点，然后获取第二接入节点的设备能力。
第二接入节点可能为一个，也可能为多个，当第二接入节点为多个时，则分别确定每个第二接入节点的设备能力是否支持该无线终端的设备类型和/或业务类型。
确定第二接入节点的设备能力是否支持无线终端的设备类型和/或业务类型的方式有三种，分别为：根据无线终端的设备类型和第二接入节点的设备能力，确定第二接入节点是否支持无线终端的设备类型；或根据无线终端的业务类型和第二接入节点的设备能力，确定第二接入节点是否支持无线终端的业务类型；或根据无线终端的设备类型和业务类型，以及第二接入节点的设备能力，确定第二接入节点是否支持无线终端的设备类型和业务类型；具体方式与上述实施例中的确定方式相似，在此不再赘述。
如果第二接入节点支持无线终端的设备类型和/或业务类型，则确定该第二接入节点为目标接入节点。指示由该第二接入节点将该无线终端接入无线通信网络。此时，无线终端需要由第一接入节点更换为第二接入节点接入网络。
进一步地，如果存在多个支持无线终端的设备类型和/或业务类型的第二接入节点，则确定哪个第二接入节点作为目标接入节点的方式有多种，例如：随机选择一个第二接入节点作为目标接入节点；或者，获取无线终端对多个第二接入节点进行测量的测量报告，根据测量报告选择无线终端接收信号强度或信号质量最强的第二接入节点作为目标接入节点，本发明实施例并不限制当存在多个支持无线终端的设备类型和/或业务类型的第二接入节点时，确定目标接入节点的方式。
如果第一接入接入节点不支持该无线终端的设备类型和/或业务类型，且第二接入节点也不支持该无线终端的设备类型和/或业务类型，则说明不存在支持该无线终端的设备类型和/或业务类型的接入节点，则将无线终端的设备类型和/或业务类型与可接入的接入节点所提供的服务质量进行匹 配，确定服务质量匹配程度最高的接入节点作为次目标接入节点。指示由该服务质量匹配程度最高的接入节点将无线终端接入网络。如果该服务质量匹配程度最高的接入节点为第一接入节点，则继续由第一接入节点将该无线终端接入网络，无需更换接入节点；如果该服务质量匹配程度最高的接入节点为第二接入节点，则由第二接入节点将该无线终端接入网络，即无线终端需要由第一接入节点更换至第二接入节点接入网络，核心网设备指示由次目标接入节点将无线终端接入无线网络的执行方法可以和核心网设备指示由目标接入节点将无线终端接入无线网络的执行方法相同。
需要说明的是，当第一接入节点不支持无线终端的设备类型和/或业务类型，且该无线终端不存在其他可接入的接入节点，即不存在第二接入节点时，也属于不存在支持无线终端的设备类型和/或业务类型的接入节点的情况，此时可以将无线终端的设备类型和/或业务类型与可接入的接入节点所提供的服务质量进行匹配，确定服务质量匹配程度最高的接入节点作为次目标接入节点接入无线终端，也可以继续由第一接入节点将该终端接入网络。
在本发明实施例中，核心网设备根据无线终端的设备类型和/或业务类型、以及无线终端可接入的接入节点的设备能力，确定设备能力能够支持无线终端的设备类型和/或业务类型的接入节点作为目标接入节点，并指示目标接入节点将该无线终端接入网络。将不同设备类型或业务类型的终端，接入符合其业务需求的接入节点，实现了为无线终端提供更优质的通信质量。
实施例2
图3为本发明实施例2中另一种无线通信接入方法的流程示意图。如图3所示，本实施例的无线通信接入方法的执行主体为核心网设备，该方法包括：
S301：接收第一接入节点发送的第一连接请求；
其中，第一连接请求中携带无线终端的设备类型和/或业务类型。
S303：根据所述无线终端的设备类型和/或业务类型，以及所述无线终端可接入的接入节点的设备能力，确定目标接入节点；
其中，核心网设备根据无线终端的设备类型和/或业务类型，以及该无 线终端可接入的接入节点的设备能力，确定设备能力能够支持无线终端的设备类型和/或业务类型的第二接入节点作为目标接入节点。步骤301和步骤303的执行过程参照上述实施例中对应的方法步骤，具体实现过程基本相同，在此不再赘述。
可选地，核心网设备接收第一接入节点发送的第一连接请求之后，核心网设备对该无线终端进行鉴权。具体地，第一连接请求中可以携带无线终端的标识，核心网设备通过无线终端的标识，查询该无线终端所对应的用户签约数据，根据签约数据确定该无线终端支持的鉴权方式，然后对该无线终端进行鉴权。或者，第一连接请求中携带无线终端的设备类型和/或业务类型，根据该无线终端的设备类型和/或业务类型确定该无线终端支持的鉴权方式，然后对该无线终端进行鉴权。或者，第一连接请求中携带该无线终端支持的鉴权方式和鉴权参数，核心网设备根据该终端支持的鉴权方式和鉴权参数对该无线终端进行鉴权。鉴权通过后，核心网设备根据签约数据中该无线终端支持的安全信息，对该无线终端进行加密和/或完整性保护，建立安全连接。
核心网设备指示由该第二接入节点将该无线终端接入无线通信网络，因此无线终端需要由第一接入节点更换至第二接入节点接入网络，具体步骤如下：
S305：发送第一连接响应至所述第一接入节点；
其中，第一连接响应为核心网设备响应于第一连接请求的响应消息，其中携带指示所述无线终端连接至所述第二接入节点的重定向信息。
S307：接收所述第二接入节点发送的第二连接请求；
其中第二连接请求为无线终端根据第一连接响应中携带的重定向信息，向第二接入节点重新发起的连接请求，第二连接请求和第一连接请求为同一连接请求事务。第二接入节点收到第二连接请求后，转发该第二连接请求至核心网设备。
S309：根据所述第二连接请求，发送第二连接响应至所述第二接入节点。
其中，第二连接响应为核心网设备响应于第二连接请求的响应消息。
具体地，核心网设备根据无线终端的设备类型和/或业务类型、以及无 线终端可接入的接入节点的设备能力，确定第二接入节点作为目标接入节点后，核心网设备发送携带指示无线终端连接至第二接入节点的重定向信息的第一连接响应至第一接入节点。其中，该重定向信息包含第二接入节点的标识。
第一接入节点收到携带该重定向信息的第一连接响应后，发送该第一连接响应至无线终端。进一步地，第一连接响应中还可以携带第一接入节点拒绝该无线终端的第一连接请求的标识。
无线终端收到该第一连接响应后，根据该第一连接响应中携带的重定向信息，确定需要通过第二接入节点接入网络。无线终端根据该重定向信息，发送第二连接请求至第二接入节点。其中第二连接请求中可以携带该无线终端中的设备类型和/或业务类型，也可以根据重定向信息确认第二接入节点为重定向后的目标接入节点，因此确定不在第二接入节点中携带该无线终端中的设备类型和/或业务类型，以节省信令开销。
第二接入节点转发该第二连接请求至核心网设备。可选地，第二接入节点收到第二连接请求后，可以默认设置与第一接入节点的行为模式相同，即第二接入节点将其设备能力携带于第二连接请求中，发送至核心网设备。
进一步地，无线终端可以在第二连接请求中携带指示所述第二连接请求与所述第一连接请求属于同一连接事务的事务标识。以供第二接入节点根据该事务标识确定该第二连接请求为重定向的终端连接请求，而无需在第二连接请求中携带其设备能力发送至核心网设备。或者，以供核心网设备根据该事务标识确定该第二连接请求为重定向的终端连接请求，核心网设备无需对发送第二连接请求的无线终端再次进行目标接入节点的确定。该事务标识可以替换为指示第二接入节点为目标接入节点的指示信息，或指示核心网设备无需执行目标接入节点的确定操作的指示信息。
核心网设备收到第二连接请求后，根据连接请求的具体事务不同，核心网设备分别作以下不同的处理：
1、当第二连接请求为注册请求时，核心网设备收到第二连接请求后，为无线终端建立承载，存储终端上下文。
核心网设备对无线终端进行注册，并为该无线终端建立承载，该承载 为核心网内部网关(例如4G网络中服务网关S-GW与分组数据网络网关PDN GW)之间的承载。具体地，核心网设备获取无线终端的签约数据，确定签约数据中是否存在与该无线终端的设备类型和/或业务类型对应的QoS，如果有对应的QoS，则根据该对应的QoS为该无线终端建立承载，如果没有对应的QoS，则根据该无线终端的设备类型和/或业务类型确定QoS，然后建立承载。或者直接根据该无线终端的设备类型和/或业务类型确定QoS，建立承载。该QoS可以是不保证比特率(Non-GBR:Non-Guaranteed Bit Rate)的,也可以是保证比特率(GBR:Non-Guaranteed Bit Rate)的，即该承载可以是GBR承载或Non-GBR承载。
2、当第二连接请求为位置更新请求或终端上下文更新请求或业务请求时，核心网设备根据第二连接请求，完成该无线终端的位置更新或终端上下文更新或业务请求。由于核心网设备已经为无线终端建立了承载，因此无需重新建立承载。
核心网设备发送响应于第二连接请求的第二连接响应至第二接入节点，第二连接响应用于指示核心网设备接受无线终端的第二连接请求。根据连接请求的具体事务不同，第二连接响应中分别携带不同的信息：

或者，第二连接响应中仅携带指示核心网设备接受该无线终端注册请求的指示信息，不携带为无线终端建立无线连接承载的配置信息。第二接入节点收到该第二连接响应后，第二接入节点通知无线终端其注册请求已被核心网设备接受，暂时不建立无线连接承载和用于传输数据的无线承载。
2、当第二连接请求为位置更新请求或终端上下文更新请求时，第二连接响应中携带核心网设备接受位置更新请求或终端上下文更新请求的信息、以及核心网设备确定的第二接入节点为无线终端建立无线连接承载的配置信息，以供第二接入节点根据第二连接响应中携带的为无线终端建立无线连接承载的配置信息，为无线终端建立无线连接承载。
或者，第二连接响应中携带核心网设备接受位置更新请求或终端上下文更新请求的信息，以供第二接入节点收到该第二连接响应后，通知无线终端其位置更新请求或终端上下文更新请求已被核心网设备所接受，暂时不建立无线连接承载和用于传输数据的无线承载。
