Description

一种网络接入方法及装置
本申请要求于2016年05月31日提交中国专利局、申请号为201610380289.3、发明名称为“一种网络接入方法及装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本发明涉及网络技术领域,尤其涉及一种网络接入方法及装置。
背景技术
随着移动终端的增加以及用户业务种类的多样化,未来移动通信网络对容量的需求越来越大,单纯的蜂窝网络或无线局域网(WirelessLocalAreaNetworks,WLAN)已经不能满足需求,业界提出开放无线网络架构(Open Wireless Architecture,OWA)技术,整合所有的无线(甚至包括有线)技术和网络,融合各种接入网络为终端提供统一的接入和一致的使用体验。而在OWA多网络统一控制的模式下,如何让用户选择合适的接入网络并达到良好的用户体验,需要有统一的控制机制。
现有***移动通信***(Long Term Evolution,LTE)中终端设备(terminal Equipment,UE)分为两个状态RRC-connected状态和RRC_Idle;当UE在RRC-connected状态时,UE当前所连接的基站(Base Station,BS)可以配置UE进行测量上报,从而支持对UE移动性控制,实现接入网络切换。具体实现包括:
首先,BS将测量配置下发给UE;其中,测量配置可包括测量对象(如所测量的小区列表及关联参数,如载频及偏移量等)、UE上报的准则和测量间隙等等;
UE则根据测量配置进行测量得到测量报告,并将测量报告上报给BS;
BS根据UE上报的测量报告判断是否控制UE进行接入网络切换。
如图1所示,如果BS根据该测量报告确定将UE从源小区切换到相邻的目标小区;以目标小区与源小区属于不同BS但属于同一移动性管理实体(Mobility Management Entity,MME)的情况为例,源小区属于的源BS向目标小区所属的目标BS发送切换请求,并在切换请求中携带UE当前的业务信息;目标BS则根据接收的UE业务信息进行准入控制和无线资源配置后,回复切换确认消息给源BS,消息中包括准入结果和无线资源配置信息;源BS则将切换确认消息转发给UE,并命令UE进行切换,UE则根据无线资源配置信息在目标BS完成接入。
在OWA多网络统一控制的模式下,若沿用上述接入网络切换方法,根据测量报告选择信号质量最好的小区,则UE需要同时对所有网络进行测量上报,会浪费大量的功率资源和信令资源。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚,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,所描述的实施例是本发明一部分实施例,而不是全部的实施例。
实施例一
因为在OWA中需要整合所有的无线(甚至包括有线)技术和网络,本发明实施例提供的方案将各种接入网络进行融合,为终端提供统一的接入和一致的使用体验。本发明实施例提供一种网络接入方法,该方法应用在OWA中,该方法包括(如图2所示):
步骤201,网络侧设备接收第一网络对应的第一网络节点发送的切换触发信息;其中,所述切换触发信息用于触发判断是否切换第一网络节点所连接的UE的接入网;
步骤202,所述网络侧设备根据所述切换触发信息判断需要将所述UE切换到第二网络时,则控制所述第二网络对应的第二网络节点与所述UE建立连接;其中,所述第一网络与所述第二网络的类型不相同。
在该实施例中,第一网络和第二网络分别可以是蜂窝网络、集群网、专用网、无线局域网等。
下面以无线局域网与蜂窝网络之间的切换为例,对本发明实施例所提供的网络接入方法做进一步详细的说明,具体包括:
方式一、当所述第一网络为无线局域网,所述第二网络为蜂窝网络时,则该方法的具体实现为终端设备由无线局域网切换到蜂窝网络,网络侧设备可以根据网络的信号质量判断是否进行UE的接入网切换,其中具体实现方式可以是:
所述网络侧设备接收到所述切换触发信息后,确定所述第一网络的信号质量是否满足所述UE的服务需求,如果不能满足,则确定需要将所述UE切换到第二网络。
其中,在该实施例中检测网络的信号质量是否满足UE的服务需求可以通过判断一下参数中的一个或者是几个的组合:
如参考信号接收功率(RSRP:Reference Signal Receiving Power),参考信号接收质量(RSRQ:Reference Signal Receiving Quality),接收信号强度指示(RSSI:Received Signal Strength Indicator),信干噪比(SINR:Signal to I nterference Noise Ratio),参考信号信干噪比(RS-SINR:RS-Signal to Interference Noise Ratio)等等。
在该方式中,切换触发信息可以是所述UE发起的呼叫事件;也可以是第一测量报告,所述第一测量报告指示所述第一网络的信号质量不满足所述UE的服务需求;其中,所述第一测量报告根据UE的测量上报或者第一网络节点测量所述UE发送的导频信号生成。
在该方式中,为了将UE切换到满足条件的网络节点,在该方式下控制所述第二网络对应的第二网络节点与所述UE建立连接之前,还通过以下方式确定第二网络节点,具体包括:
A,根据UE上报的网络节点信息中确定第二网络节点:
所述网络侧设备从所述切换触发信息中获取所述第二网络的网络节点信息;
所述网络侧设备根据所述网络节点信息从所述第二网络对应的网络节点中确定所述第二网络节点。
B,可以直接通过定位方式确定第二网络节点;另外,也可以是经过方式A筛选后,还有多个可选的网络节点则还可以进一步通过定位方式确定一个确定的网络节点作为第二网络节点;具体实现可以是:
所述网络侧设备获取所述UE的定位信息;
所述网络侧设备根据所述定位信息从所述第二网络对应的网络节点中确定信号覆盖所述UE的至少一个网络节点作为所述第二网络节点。
技术上述方式确定了某一个网络节点为第二网络节点后,可以通过以下方式将UE切换到第二网络节点,控制所述第二网络对应的第二网络节点与所述UE建立连接包括:
所述网络侧设备发送服务通知消息到所述第二网络节点;其中,所述服务通知消息用于指示所述第二网络节点为所述UE分配网络资源;
所述网络侧设备接收所述第二网络节点为所述UE分配的网络资源的配置信息;
网络侧设备通过所述第一网络节点发送所述配置信息到所述UE,使得所述UE根据所述配置信息指示的网络资源与所述第二网络节点建立连接。
二、当所述第一网络为蜂窝网络,所述第二网络为无线局域网,因为无线局域网对于大部分用户来说都具有传输速度快、费用低的优点,所以UE所处的环境中有信号质量符合要求的无线局域网,即使当前蜂窝网络信号质量满足条件的情况下,最优化的方式也是切换到无线局域网;所以UE当前与蜂窝网络连接,则会实时的检测周围无线局域网的新到质量。所以在该方式中:
所述切换触发信息可以是第二测量报告,所述第二测量报告指示所述第二网络的信号质量满足所述UE的服务需求。
在该方式中,控制所述第二网络对应的第二网络节点与所述UE建立连接之前,进一步包括:
因为在第二测量报告中可以携带的信息信号质量满足所述UE的服务需求的第二网络的网络节点的标识,网络侧设备可以根据该标识直接确定第二网络节点,具体实现可以是:
所述网络侧设备从所述第二测量报告中获取所述第二网络对应的至少一个蜂窝网络节点;
从所述至少一个蜂窝网络节点中确定至少一个网络节点作为所述第二网络节点。
在该实施例中,如果第二测量报告中只包括第二网络的一个网络节点,网络侧设备则可以直接将该网络节点确定为UE连接的第二网络节点;如果从第二测量报告中确定了第二网络对应的多个网络节点,则在该方法中还可以通过网络节点的负载信息、信号强度与UE之间的距离等信息从多个中确定至少一个网络节点作为第二网络节点,下面以负载信息为例对确定第二网络节点的具体实现做详细说明,包括:
确定所述至少一个蜂窝网络节点的负载信息;
根据所述负载信息从所述至少一个蜂窝网络节点中确定负载小于设定阈值的网络节点作为所述第二网络节点。
实施例二
如图3所示,在该实施例中,基于网络节点侧设备实现一种网络接入方法,该方法应用在OWA中,该方法包括:
步骤301,第一网络对应的第一网络节点发送切换触发信息到网络侧设备;其中,所述切换触发信息用于所述网络侧设备判断是否对所述第一网络节点所连接的UE的接入网进行切换;
步骤302,所述第一网络节点当接收到所述网络侧设备反馈的切换命令,则将所述切换命令转发到所述UE,使得所述UE根据所述切换命令与第二网络对应的第二网络节点建立连接;其中,所述第一网络与所述第二网络的类型不相同。
下面以无线局域网与蜂窝网络之间的切换为例,对本发明实施例所提供的网络接入方法做进一步详细的说明,具体包括:
方式一、当所述第一网络为无线局域网,所述第二网络为蜂窝网络时;
第一网络对应的第一网络节点发送切换触发信息到网络侧设备具体实现方式可以是:
A,当所述第一网络节点接收到所述UE发送的呼叫,则根据所述呼叫发送切换触发信息到所述网络侧设备。
B,所述第一网络节点根据所述UE发送的测量上报或测量所述UE发送的导频信号,确定自身信号质量不满足所述UE的服务需求,则发送所述切换触发信息到所述网络侧设备。
方式二、当所述第一网络为蜂窝网络,所述第二网络为无线局域网时;
因为无线局域网络相对于蜂窝网络有传输速度快、费用低的优点,所以UE在选择接入网时,优先选择符合条件的无线局域网,即使UE当前正通过蜂窝网络进行数据传输,也同时扫描区域范围内的无线局域网络,如果扫描信号质量满足UE需求的无线局域网络,则请求切换到扫描到的无线局域网络,具体实现可以是:
第一网络节点将UE上报的无线局域网络信息上报至网络侧;其中,无线局域网络信息包括无线局域网网络节点的ID,无线局域网的信号质量测量报告,UE的信息,包括UE的ID,UE当前的业务信息等;
实施例三
如图4所示,在该实施例中,基于终端设备实现一种网络接入方法,该方法应用在OWA中,该方法包括:
步骤401,UE通过当前连接的第一网络的第一网络节点发送切换触发信息到网络侧设备;其中,所述切换触发信息用于所述网络侧设备判断是否对所述UE的接入网进行切换;
步骤402,UE接收到所述网络侧设备发送的到所述网络侧设备反馈的切换命令,则根据所述切换命令与第二网络对应的第二网络节点建立连接;其中,所述第一网络与所述第二网络的类型不相同。
可选的,当所述第一网络为无线局域网,所述第二网络为蜂窝网络时,UE通过当前连接的第一网络的第一网络节点发送切换触发信息到网络侧设备之前,可以通过以下方式生成切换触发信息:
A,UE检测到所述第一网络的当前信号质量低于设定的第一门限,则检测蜂窝网络,并根据检测到的蜂窝网络生成所述切换触发信息。
B,UE检测无线局域网络的信号质量,如果检测到的无线局域网络的信号质量高于预设的第二门限,则生成所述切换触发信息。
基于上述方式网络侧设备为UE选择了具体的第二网络节点之后,UE可以通过以下方式与第二网络节点建立连接,包括:
所述UE接收到所述切换命令,根据所述切换命令中携带的资源配置信息与所述第二网络对应的第二网络节点。
以下实施例结合UE、网络节点以及网络侧设备三方交互流程,对本发明实施例提供的一种网络接入方法作进一步详细的说明:
实施例四
如图5所示,第一网络为WiFi网络、第二网络为蜂窝网络融合的通信***架构,本 发明实施例提供的一种网络接入方法的具体实现包括:
步骤501:当UE驻留在WiFi网络中,UE向第一网络节点(即WiFi AP)发送切换触发信息;
在该实施例中,该切换触发信息可以包括两种情况:
1、UE发起的呼叫,在UE发起呼叫时需要有对应的网络给UE提供网络资源,所以这个时候网络侧设备可以根据各网络的信号质量确定将UE连接到信号质量好的网络,对应的则会触发网络侧设备对UE的接入网进行切换判断。其中,该呼叫中可以携带UE ID、UE的信道测量报告,UE请求的服务类型,UE的定位信息等内容。
2、UE驻留在第一网络时,如果第一网络的信号质量低于一定的门限值时,则会对应的检测可以提供服务的蜂窝信号,当检测到信号质量满足条件的蜂窝网络,则基于检测到的蜂窝网络的生成切换触发信息。在该实施例中,因为UE驻留在第一网络的情况包括连接态和空闲态,所以该实现方式中不管UE与第一网络节点处于数据交互状态下或者是空闲状态下,只要第一网络的信号质量低于一定的门限值,UE则可以检测满足服务需求的蜂窝网络。
步骤502:WiF i AP向网络侧上报切换触发信息;该切换触发信息中可以携带UE信息,信道质量等信息;
步骤503:若网络侧根据WiFi AP上报的内容判断WiFi网络不能为UE提供服务,网络侧设备根据WiFi AP上报的内容决策将UE切换至蜂窝网络,并选取一个或多个蜂窝节点为UE提供服务;
步骤504:网络侧向选取的蜂窝节点发送服务UE的请求;
步骤505:蜂窝节点收到请求后进行资源配置,并发送至网络侧;
步骤506:网络侧将蜂窝网络配置发送至原WiFi AP,通知将UE切换至蜂窝网络;
步骤507:WiFi AP向UE发送切换至蜂窝网络的命令,并将蜂窝网络配置转发给UE,以使UE接入选取的蜂窝节点
实施例五
如图6所示,该实施例中第一网络为蜂窝网络,第二网络为WiFi网络,则当UE使用蜂窝网络进行通信的过程中,检测到WiFi网络的信号质量达到满足服务的需求,则将UE切换到WiFi网络具体实现包括:
步骤601:当UE连接到蜂窝节点正在进行数据通信,UE同时检测WiFi信号,当WiFi信号满足一定条件时上报至当前连接的蜂窝节点;
步骤602:蜂窝节点将WiFi网络信息上报至网络侧,可上报包括WiFi AP的ID,WiFi信道质量测量报告,并携带UE的信息,包括UE的ID,UE当前的业务信息;
步骤603:网络侧接收到蜂窝节点上报的WiFi信道质量报告,判断是否将UE切换至WiFi网络;
其中,可以根据WiFi网络的负载判断是否切换至WiFi网络,若满足服务信号质量的WiFi AP当前的负载低于一定门限,则确定将UE切换至满足条件的WiFi AP;
步骤604:若网络侧决策将UE切换至WiFi网络,则向当前连接的蜂窝节点发送切换WiFi网络的命令;
步骤605:蜂窝节点向UE发送切换WiFi网络的命令;
步骤606:UE中断蜂窝网络连接,接入到WiFi网络;
步骤607:UE连接的WiFi AP通知网络侧UE已连接到WiFi网络。
实施例六

接收单元701,用于接收第一网络对应的第一网络节点发送的切换触发信息;其中,所述切换触发信息用于触发判断是否切换第一网络节点所连接的UE的接入网;
处理单元702,用于根据所述切换触发信息判断需要将所述UE切换到第二网络时,则控制所述第二网络对应的第二网络节点与所述UE建立连接;其中,所述第一网络与所述第二网络的类型不相同。
可选的,当所述第一网络为无线局域网,所述第二网络为蜂窝网络时,所述处理单元具体用于接收到所述切换触发信息后,确定所述第一网络的信号质量是否满足所述UE的服务需求,如果不能满足,则确定需要将所述UE切换到第二网络。
