Description

网络接入处理方法、装置、RAN设备及SGSN 技术领域
本发明涉及通信领域，具体而言，涉及一种网络接入处理方法、装置、无线接入网络(Radio Access Network，简称为RAN)设备及服务通用分组无线服务(General Packet Radio Service，简称为GPRS)支持节点(Serving GPRS Support Node，简称为SGSN)。
背景技术
现有的第二代(2nd Generation，简称为2G)和第三代(3rd Generation，简称为3G)通信网络通常包括RAN和核心网络(Core Network，简称为CN)两部分。其中，核心网络从逻辑上可分为主要处理语音业务的电路交换域(Circuit Switched Domain，简称为CS)和主要处理分组业务的分组交换域(Packet Switched Domain，简称为PS)。
图1是相关技术中2G/3G网络的结构示意图，如图1所示，其包括如下网元：
SGSN为PS域控制面功能实体，临时存储用户数据的服务器，负责管理和存储用户设备(User Equipment，简称为UE)的上下文(例如，UE/用户标识、移动性管理状态、用户安全参数等)，为用户分配临时标识，当UE驻扎在该跟踪区域或者该网络时，负责对该用户进行鉴权；处理SGSN和UE之间的所有非接入层消息；触发在PS域内的寻呼。
移动交换中心(Mobile Switched Center，简称为MSC)为CS域功能实体，负责用户呼叫的建立和释放。
归属位置服务器(Home Location Register，简称为HLR)永久存储用户签约数据，HLR存储的数据包括UE的国际移动用户识别码(International Mobile Subscriber Identification Number，简称为IMSI)。
在实际运营的移动通信网络中，运营商为了节省设备的投资，一个无线接入网络RAN可能被多个运营商共享使用，这个技术称为无线共享(RAN sharing)技术。即使通信网络中使用了RAN sharing技术，但是CS域和PS域还是应该由同一个运营商为用户服务，否则会造成计费复杂及网络中的信令开销更大。图2是相关技术中使同 一个运营商的CS域和PS域网络为UE服务的流程图，如图2所示，该流程包括如下步骤：
步骤S201，UE向无线RAN发送位置区更新请求(Location Area Update Request，简称为LAU request)消息，在2G系统中RAN是BSS，而在3G系统中RAN指RNC；
步骤S202，RAN转发LAU request消息，并在消息中携带重定向尝试指示，查询UE是否已经注册；
步骤S203，MSC向RAN返回重定向指示消息，消息中携带IMSI，CS/PS协作请求，UE未注册的指示；此IMSI可以是由MSC向UE直接获取的；
步骤S204，RAN向所有与之有连接的SGSN发送确认用户是否注册的请求消息，请求消息中携带IMSI；
步骤S205，收到消息的SGSN如果确认用户已经在该SGSN注册，就回复确认用户已经注册消息，并携带用户的IMSI；如果用户没有在该SGSN注册，就回复确认用户未注册消息，消息中携带请求消息中的IMSI；
步骤S206，根据步骤S205中返回的确认用户已经注册消息的SGSN，RAN可以确认UE在PS域所使用的公共陆地移动网络标识(Public Land Mobile Network Identifier，简称为PLMN ID)，从而选择一个合适的MSC，RAN向所选择的MSC转发LAU request消息；如果所有的SGSN都回复确认用户未注册消息，RAN可以任意选择MSC，并向所选择的MSC转发LAU request消息；
步骤S207，MSC接受UE的请求消息，并向RAN返回位置区更新接受消息；消息中携带新分配的临时移动用户标识(Temporary Mobile Subscriber Identity，简称为TMSI)以及UE注册的位置区标识(Location Area Identifier，简称为LAI)；
步骤208，RAN向UE转发位置区更新接受消息。
可见，在相关技术中，为了实现CS域和PS域由同一个运营商服务的目的，在步骤S204中，RAN向所有与之有连接的SGSN都发送消息。从这个过程可以看出，RAN选择同一个运营商的SGSN接入的时间比较长，造成比较差的用户体验；另一方面，RAN向网络侧发送的信令较多，也容易造成网络的拥塞；另外还需要运营商网络中所有的SGSN都进行升级，这就造成了运营商投资成本的增加。
因此，在相关技术中，RAN选择由同一个运营商提供服务的接入时间长，以及资源浪费，成本高的问题。

具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
在本实施例中提供了一种网络接入处理方法，图3是根据本发明实施例的网络接入处理方法的流程图，如图3所示，该流程包括如下步骤：
步骤S302，接收用户设备UE发送的接入请求，其中，该接入请求的类型可以为多种，例如，可以为以下至少之一：位置区更新请求LAU、附着请求、路由区更新请求(Routing Area Update Request，简称为RAU request)；
步骤S304，获取预先存储的UE已经注册接入的第一接入域的第一接入节点所属运营商网络的网络信息；
步骤S306，依据获取的网络信息，选择与第一接入域同属于运营商网络的第二接入域的第二接入节点；

通过上述步骤，依据获取的预先存储的UE已经注册接入的第一接入域的第一接入节点所属运营商网络的网络信息，选择与该第一接入域同属于运营商网络的第二接入域的接入节点，即通过预先存储的信息，可以快速地确定接入UE的第二接入域的接入节点，相对于相关技术中需要搜寻可能的接入节点，RAN选择由同一个运营商提供服务的接入时间长，以及资源浪费，成本高的问题，进而达到了不仅能够有效降低成本，而且提高由同一运营商提供不同接入域服务的效率。
其中，UE已经注册接入的运营商网络的网络信息可以包括多种信息，例如，可以包括以下至少之一：UE已经注册接入的运营商网络的注册接入节点信息、UE已经注册接入的运营商网络的公共陆地移动网络PLMN信息。
优选地，在接收UE发送的接入请求之前，还可以在UE注册接入运营商网络结束后，将UE注册接入的运营商网络的网络信息存储在节点信息寄存器中。
在获取预先存储的UE已经注册接入的第一接入域的第一接入节点所属运营商网络的网络信息时，可以采用多种方式，例如，可以采用以下较为简单快速的处理方式，通过在节点信息寄存器中预先存储的网络信息中查找UE的国际用户识别码IMSI的方式，获取UE已经注册接入的第一接入域的第一接入节点所属运营商网络的网络信息。
优选地，上述第一接入域为电路域时，第二接入域可以为分组域；上述第一接入域为分组域时，第二接入域可以为电路域。
在本实施例中还提供了一种网络接入处理装置，该装置用于实现上述实施例及优选实施方式，已经进行过说明的不再赘述。如以下所使用的，术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。

针对相关技术中的上述问题，在本实施例中提供了一种网络接入处理的方法，该方法包括如下处理：共享RAN在位置区更新结束或者路由区更新结束时并且选择了PLMN，共享RAN将用户的PLMN信息或者节点信息存储在用户节点信息寄存器中；共享RAN在下次用户接入的时候先去用户节点信息寄存器中查询用户已经注册的节点或者PLMN信息，然后根据查询到的节点信息或者PLMN信息进行选择节点；共享RAN将非接入层消息(包括LAU请求，Attach请求，RAU请求)都发送至用户节点信息寄存器，由节点信息寄存器来确定UE是否已经在一个PLMN进行注册，如果未注册，共享RAN任意选择一个PLMN供UE接入，如果已经在一个PLMN注册，共享RAN选择已经注册的PLMN供UE接入。
通过上述处理，不仅解决了相关技术的上述的问题，而且提升了网络运营的效率，提高了用户体验，避免了运营商升级所有的网络设备。
