Description

重定向方法、设备及*** 技术领域
本发明实施例涉及通信技术，尤其涉及一种重定向方法、设备及***。
背景技术
长期演进(Long Term Evolution，简称LTE)是由第三代合作伙伴计划(The 3rd Generation Partnership Project，简称3GPP)组织制定的通用移动通信***(Universal Mobile Telecommunications System，简称UMTS)技术标准的长期演进。LTE作为新一代移动通信技术，能够提供更高的用户速率、更低的时延和更丰富的业务，同时大大提高用户体验。但LTE网络的建设是一个漫长的过程，在这个过程中，会存在LTE信号覆盖不好的区域。当用户设备在LTE覆盖不好的区域，会向网络侧发送用户设备当前接入小区的信号质量测量报告，网络为了避免出现业务中断的问题，提高用户良好的业务体验感知，会发送重定向命令要求用户设备(User Equipment，简称UE)重定向到3G网络。
由于用户设备的设计限制和业务冲突等原因，用户设备进行重定向时，会出现无法连接3G网络的情况，导致用户设备无法成功的重定向到3G网络。例如，目前大部分码分多址(Code Division Multiple Access，简称CDMA)终端支持语音和LTE数据并发(Simultaneous Voice and LTE，简称SVLTE)，却不支持语音和EV-DO数据并发(Simultaneous Voice and EV-DO，简称SVDO)，因此当用户设备在通话时，此时用户设备的CDMA模块占有了射频资源，用户设备的3G模块无法获得射频资源，导致用户设备无法连接到3G网络。因此，现有技术中用户设备收到网络侧下发的重定向命令，用户设备根据重定向命令执行重定向操作，由于某种原因导致无法连接到3G网络，将导致用户设备长时间处于没有可用的3G或者LTE网络的状态，严重的影响了用户正常业务的进行。

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。
本发明的实施例可以应用于CDMA、UMTS和LTE网络以及以后演进的网络互操作。重定向是指UE断开与当前网络的连接后接入另一个制式的网络。通常涉及两个过程：1)离开当前网络，UE断开与当前网络连接，进入空闲态，网络侧通过重定向命令指示UE在离开连接态后要尝试驻留到指定的***/频点，重定向命令中会携带目标重定向网络的频点信息，以帮助UE快速接入新的网络；2)接入新的网络，UE根据网络侧提供的目标重定向网络频点信息，进行接入并发起业务。为了更清楚地说明本发明的实施方案，下面以LTE网络重定向至3G网络为例进行详细说明。
图1为一种用于模拟重定向的***示意图，如图1所示，该***包括演进型基站(evolution Node B，简称eNB)和UE。当UE通过处理器12检测到当前接入小区的信号强度变差且低于eNB要求上报重定向门限时，UE将通过发送器11向eNB上报测量报告事件。eNB通过接收器23接收到UE发送的测量报告事件后，eNB的处理器22根据测量报告生成携带目标重定向网络的频点信息的重定向命令，并通过发送器21将重定向命令发送给UE，要求UE重定向到指定的网络。UE通过接收器13收到重定向命令后，处理器12启动重定向定时器，使UE在定时时间内向指定网络发起重定向。
图2为本发明实施例提供的一种重定向方法流程图，如图2所示，本实施例提供的重定向方法包括以下步骤：
S21，用户设备确定当前接入小区的信号质量低于设定门限；
S22，判断所述用户设备是否满足设定条件；
S23，若判断所述用户设备满足所述设定条件，则允许向网络侧发送测量报告，以使所述网络侧根据所述测量报告向所述用户设备发送重定向命令；
S24，接收所述重定向命令，所述重定向命令携带有待重定向的小区的信息；
S25，根据所述重定向命令在定时时间内向所述待重定向的小区发起重定向。
具体的，在本实施例中，可以根据UE所支持的网络制式和业务状态设定判断条件。
示例性的，若UE为CDMA终端，由于目前大部分CDMA终端支持SVLTE模式，却不支持SVDO模式，因此当用户设备在通话时，此时用户设备的CDMA模块占有了射频资源，其3G模块无法获得射频资源，导致无法连接到3G网络。因此，判断UE是否处于通话状态，若UE处于非通话状态，则UE的当前状态适合进行重定向，即可以判定UE满足上报测量报告的设定条件。若UE处于通话状态，还可以进一步判断UE是否支持SVDO模式，若UE支持SVDO模式，则UE的当前状态依然适合进行重定向；若UE不支持SVDO模式，则UE的当前状态不适合进行重定向，即可以判定UE不满足上报测量报告的设定条件。需要说明的是，上述示例仅用于说明本实施中重定向过程中UE的设定条件的设定依据，并非限定性的。对于CDMA终端，还可以有其他的设定条件，例如终端不支持搜索EVDO或者EVDO频点由于接入试探失败等原因被规避，还没有清除等。
可以理解，若UE为支持其他网络制式的终端，如宽带码分多址(Wideband Code Division Multiple Access，简称WCDMA)或时分同步码分多址(Time Division-Synchronous Code Division Multiple Access，简称TD-SCDMA)，同样可以根据用户设备的设计限制和业务状态等条件来判断UE的当前状态适合进行重定向。例如，WCDMA制式的UE，若所插卡不支持WCDAM网络或WCDMA网络鉴权失败，导致不能连接WCDMA，此时应该避免重定向到WCDMA。
在本实施例中，UE接收网络侧发送的重定向命令之后，可以启动一个定时器执行重定向，定时器用于设置执行重定向的定时时间。
作为一种可选的实施方式，可以根据相关技术或UE的设计特性为定时器设置定时时间。可以理解，对于同一用户设备，定时器的定时时间是固定不变的。
作为另一种可选的实施方式，也可以通过网络侧下发的重定向命令来指示UE设置定时器的定时时间。换句话说，重定向命令还可以携带重定向时 间值，UE在接收到重定向命令之后，可以直接根据重定向命令的指示设置定时器的定时时间，并在定时时间内向待重定向的小区发起重定向。
另外需要说明的是，在实际应用中，可以根据UE已接入小区的覆盖范围和UE的移动速度等因素自适应的调节UE检测已接入小区的信号质量的间隔时间ΔT。如果UE已接入小区的覆盖范围较大或UE的移动速度很小时，则ΔT可以相应的调节得较长；如果UE已接入小区的覆盖范围较小或UE的移动速度很大时，则ΔT可以相应的调节得较短。
进一步的，如果ΔT较大时，若在T时刻，UE检测到已接入小区的信号质量低于设定门限，且判断UE不满足设定条件时，则UE不向网络侧发送测量报告。然而在ΔT1(ΔT1<ΔT)时刻后，UE不满足设定条件的状态解除，作为一种可选的实施方式，UE可以确定T+ΔT1时刻与T+ΔT时刻之间的时间间隔Δt(Δt＝ΔT-ΔT1)，若Δt大于设定时间(例如Δt>ΔT/2)，则UE可以继续将T时刻的测量报告发送给网络侧，以使网络侧根据所述测量报告向所述用户设备发送重定向命令。作为另一种可选的实施方式，UE还可在T+ΔT1时刻检测已接入小区的信号质量，若T+ΔT1时刻的信号质量低于设定门限，则将T+ΔT1时刻的测量报告发送给网络侧，以使网络侧根据所述测量报告向所述用户设备发送重定向命令。
根据重定向的基本过程可知，网络侧向UE发送重定向命令，是UE上报当前接入小区的信号强度低于eNB要求上报重定向门限的测量报告触发的。在本实施例中，通过一个事件决策器来决定是否上报测量报告给eNB。当UE检测到当前接入小区的信号质量低于设定门限时，先判断UE的当前状态是否适合进行重定向，即UE是否满足设定条件。如果UE的当前状态适合进行重定向(满足设定条件)，则向网络侧发送重定向请求，此时进行重定向使得重定向的成功率较高，UE可以快速接入网络侧要求重定向的小区。相对于直接触发网络侧向UE发送重定向命令使UE连接至指定的网络，如果UE的当前状态不适合进行重定向，则重定向成功的概率较小，若在重定向定时器设定时间内都无法完成指定网络的注册，则可能导致UE将长时间处于没有网络的状态，本实施例提供的重定向方法，可以提高重定向的成功率，UE可以快速接入网络侧指定的***/频点，有效避免用户长时间处于没有网络的状态，保障用户正常业务的进行。
作为本实施例一种可选的实施方式，若判断所述用户设备不满足所述设定条件，则可以执行S26，禁止向所述网络侧发送所述测量报告。
可以理解，如果UE的当前状态不适合进行重定向，即不满足设定条件，则重定向成功的概率较小，若在重定向定时器设定时间内都无法完成指定网络的注册，则可能导致用户设备将长时间处于没有网络的状态。如果UE的当前状态不适合进行重定向(不满足设定条件)，则暂时不向网络侧发送重定向请求，就不会触发网络侧向UE发送重定向命令，使得UE可以继续驻留在当前接入小区，保障用户正常业务的进行。
在某些情况下，即使UE没有向网络侧发送当前接入小区的信号质量的测量报告，网络侧还可能通过网络侧与UE之间的其他交互信息获知UE需要进行重定向，此时网络侧也会向UE发送重定向命令。本发明实施例为此又提供了一种如图3所示的重定向方法，其中图3为本发明实施例提供的另一种重定向方法流程图。如图3所示，该重定向方法包括以下步骤：
S31，用户设备接收网络侧发送的重定向命令，所述重定向命令携带有待重定向的小区的信息；
S32，判断所述用户设备是否满足设定条件；
S33，若判断所述用户设备不满足设定条件，则在可调节的第一定时时间内根据所述重定向命令向所述待重定向的小区发起重定向。
在本实施例中，UE在接收到重定向命令之后，可以检测UE的当前状态是否适合进行重定向，若UE的当前状态不适合进行重定向，可以启动一个动态定时器执行重定向，动态定时器用于设置可调节的第一定时时间。可以理解，所谓适合重定向的状态，就是UE具有搜索重定向目标网络的条件，比如能获取射频资源进行目标网络搜索、目标网络没有被禁止等，使用户设备可以成功的重定向到3G网络，也就是说，UE满足图2所示实施例中的设定条件。故UE当前处于不适合进行重定向状态是指UE不满足图2所示实施例中的设定条件。
作为一种优选的实施方式，可以根据UE当前接入小区的覆盖范围和所述用户设备的移动速度中的至少一个来确定动态定时器的定时时间。
具体的，可以采用一个分段线性函数
Figure PCTCN2015079369-appb-000007
来确定动态 定时器的定时时间。其中，c表示UE不满足所述设定条件的过程中请求重定向的次数，T1表示初始化所述动态定时器时间，Δ1、Δ2、Δ3和参数A、B具体可以根据所述用户设备当前接入小区的覆盖范围和所述用户设备的移动速度确定，显然B>A。示例性的，如果UE当前接入小区的覆盖范围较大或UE的移动速度较小时，则UE的当前接入小区的信号质量变化较慢，相应的动态定时器的定时时间稍长些；如果UE当前接入小区的覆盖范围较小或UE的移动速度较大时，则UE的当前接入小区的信号质量变化较快，相应的动态定时器的定时时间稍短些。
当UE收到重定向命令后，检测到UE处于不适合执行重定向的状态。若启动静态定时器进行重定向，很可能定时器设定时间内都无法完成待重定向网络的注册，则可能导致用户设备将长时间处于没有网络的状态。反之，若果采用动态的定时器，则可以实现定时器快速到期，进入重定向失败环节，然后UE发起搜索可接入小区，到达快速接入网络的目的，避免用户长时间处于没有网络的状态。
需要说明的是，本实施中之所以没有采用时间较短的静态定时器，而采用动态累加的动态定时器来实现定时器快速到期，是因为如果设置时间较短的静态定时器来实现定时器快速的到期，UE会在短时间内频繁循环的执行重定向、重定向失败、搜网注册可接入小区的过程，如此一来，就会增加UE的功耗和网络的信令负载。
进一步的，作为本实施例一种优选的实施方式，在启动动态定时器进行重定向的过程中，若在动态定时器的定时时间到达之前，UE不适合重定向的状态解除，即UE又满足了设定条件，还可以立即停止动态定时器，使动态定时器到期，直接进入重定向失败环节，然后UE发起搜索可接入小区，到达快速接入网络的目的。
另外，作为一种可选的实施方式，UE在接收到重定向命令之后，若检测到UE当前状态适合进行重定向(满足设定条件)，此时可以执行S34，在固定的第二定时时间内根据所述重定向命令向所述待重定向的小区发起重定向。示例性的，可以启动静态定时器执行重定向，静态定时器用于设置固定的第二定时时间。
进一步的，作为一种可选的实施方式，可以根据图2所示实施例提供的定时器的设定方法为静态定时器设置固定的定时时间。
本实施例提供的重定向方法，在UE接收到重定向命令之后，可以先判断UE的当前状态是否适合进行重定向。如果UE的当前状态适合进行重定向，则启动静态定时器执行重定向，此时执行重定向，使得重定向的成功率较高，UE可以快速接入待重定向的小区；如果UE的当前状态不适合进行重定向，则启动动态定时器执行重定向，实现定时器快速到期，进入重定向失败环节，然后UE发起搜索可接入小区，到达快速接入网络的目的，同时还可以避免增加UE的功耗和网络的信令负载。
本发明还提供了一种图4所示的重定向方法，其中图4为本发明实施例提供的又一种重定向方法流程图。如图4所示，本实施例提供的重定向方法包括如下步骤：
S41，用户设备确定当前接入小区的信号质量低于设定门限；
S42，判断所述用户设备是否满足设定条件；
S43，基于所述判断，若所述用户设备满足所述设定条件，则允许向网络侧发送测量报告，以使所述网络侧根据所述测量报告向所述用户设备发送重定向命令；
S44，接收所述重定向命令，所述重定向命令携带有待重定向的小区的信息；
S45，再次判断所述用户设备是否满足所述设定条件；
S46，基于所述再次判断，若所述用户设备不满足所述设定条件，则在可调节的第一定时时间内根据所述重定向命令向所述待重定向的小区发起重定向。
可以理解，在UE向网络侧发送测量报告之后，UE的业务状态可能发生变化，因此，进一步UE还可以在接收到重定向命令之后，再一次检测UE的当前状态是否适合进行重定向，即UE是否满足设定条件。显而易见的，本实施例中的设定条件与图2和图3所示实施例中的设定条件相同，可以根据用户设备所支持的网络制式和业务状态中的至少一个设定。
作为一种优选的实施方式，在UE确定当前接入小区的信号质量低于设定门限后，若判断所述用户设备不满足所述设定条件，则可以执行S47，禁止向所述网络侧发送所述测量报告。暂不触发网络侧向UE发送重定向命令，使得UE可以继续驻留在当前接入小区，保障用户正常业务的进行。
另外，在UE接收到重定向命令之后，再一次检测UE的当前状态是否适合进行重定向，若判断用户设备适合进行重定向(满足所述设定条件)，则可以执行S48，在固定的第二定时时间内根据所述重定向命令向所述待重定向的小区发起重定向。
具体实施过程中可以参照图3所示实施例提供的启动动态定时器和静态定时器来执行重定向。具体的，动态定时器和静态定时器的定时时长的设定也可以参照3所示实施例提供的设定方法。
值得一提的是，在启动动态定时器进行重定向的过程中，若在动态定时器的定时时间到达之前，UE不适合重定向的状态解除，即UE又满足了设定条件，还可以立即停止动态定时器，使动态定时器到期，直接进入重定向失败环节，然后UE发起搜索可接入小区，到达快速接入网络的目的。
本实施例提供的重定向方法，结合了图2和图3所示实施例，执行两次判断操作，进一步保障重定向的成功率，有效避免用户长时间处于没有网络的状态，保障用户正常业务的进行。

在实际应用中，处理模块52还可以用于若判断所述用户设备不满足所述设定条件，则禁止向所述网络侧发送所述测量报告。

作为一种较佳的实施方式，上述用户设备的设定条件可以根据用户设备所支持的网络制式和业务状态中的至少一个设定。
进一步的，作为一种较佳的实施方式，处理模块62具体可以包括动态定时器621。在接收模块61接收网络侧发送的重定向命令之后，处理模块62判断所述用户设备是否满足设定条件，即判断所述用户设备是否处于适合重定向的状态，若判断用户设备处于不适合重定向的状态(不满足设定条件)，则启动动态定时器621执行重定向，动态定时器621用于设置可调的第一定时时间，在可调的第一定时时间内用户设备根据重定向命令向待重定向的小区发起重定向。
进一步的，作为一种优选实施方式，可以根据用户设备当前接入小区的覆盖范围和用户设备的移动速度中的至少一个设置动态定时器621的第一定时时间。
