Description

确定驻留小区的方法、用户设备及网络设备 技术领域
本发明实施例涉及通信技术，尤其涉及一种确定驻留小区的方法、用户设备及网络设备。
背景技术
用户设备(User Equipment，简称UE)在开机后即进入空闲模式，为了获取正常服务，当选择公共陆地移动网络(Public Land Mobile Network，简称PLMN)完成之后，UE发起选择一个合适的且属于该PLMN的小区进行驻留，该过程称为小区选择过程。其中，小区选择过程要满足S准则。
服务小区和邻区的信号强度随着UE的移动而改变，所以UE需要重新选择一个最合适的小区驻留，此过程称为重选小区。其中，重选小区时，候选小区同样需要满足S准则，重选小区准则包括质量级别门限标准H和小区排队标准R，对于分层小区结构(Hierarchical Cell Structure，简称HCS)，标准H决定是否根据分层重选小区规则进行按优先级次序排队，如果系统消息指明没有使用HCS，则不使用标准H，而采用标准R。
无论是标准H还是标准R，重选小区涉及的重选参数较多，比如：频率优先级、频率偏移量和重选门限等，且网络覆盖多样性大，可能会导致UE无法满足所有的重选小区条件，从而只能驻留在当前小区。可能会存在一种情况：UE当前所驻留的小区的信号强度或者信号质量不如其他小区的信号强度或者信号质量，因此，相比较于其他小区，当前驻留小区具有较大的脱网率和呼损率等，从而降低通信的可靠性。

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。
本发明适用于在不同类型的通信系统之间确定驻留小区，也适用于在不同类型的通信系统之间确定驻留小区，这里的通信系统可以是2G的全球移动通信系统(Global System for Mobile，简称GSM)、码分多址(CodeDivisionMultipleAccess，简称CDMA)等、或者3G的时分同步码分多址(Time Division-Synchronous Code Division Multiple Access，简称TD-SCDMA)、宽带码分多址(Wideband Code Division Multiple Access，简称WCDMA)等，以及4G的分时长期演进(Time-Division Long Term Evolution，简称TD-LTE)、LTE-FDD，或者4G以后的相关制式系统等。
用户设备UE在开机后进入空闲模式，为了获取正常服务，当选择公共陆地移动网络PLMN完成之后，UE要进入小区选择过程。其中，小区选择过程要满足S准则。
S准则条件如下：
对于频分双工(Frequency Division Duplexing，简称FDD)的小区：Srxlev>0且Squal>0；
对于时分双工(Time Division Duplexing，简称TDD)的小区：Squal>0
其中：
Squal＝Qqualmeas-(Qqualmin+Qqualminoffset)
Srxlev＝Qrxlevmeas-(Qrxlevmin+Qrxlevminoffset)-Pcompensation，具体参数见表1。
表1

Figure PCTCN2015093419-appb-000002
服务小区和邻区的信号强度随着UE的移动而改变，所以UE需要重新选择一个最合适的小区驻留，此过程称为重选小区。其中，重选小区时，候选小区同样需要满足S准则，重选小区准则包括质量级别门限标准H和小区排队标准R，对于分层小区结构HCS，标准H决定是否根据分层重选小区规则 进行按优先级次序排队，如果系统消息指明没有使用HCS，则不使用标准H，而采用标准R。
无论是标准H还是标准R，重选小区涉及的重选参数较多，比如：频率优先级、频率偏移量和重选门限等，且网络覆盖多样性大，可能会导致UE无法满足所有的重选小区条件，从而只能驻留在当前小区。可能会存在一种情况：UE当前所驻留的小区的信号强度或者信号质量不如其他小区的信号强度或者信号质量，因此，相比较于其他小区，当前驻留小区具有较大的脱网率和呼损率等，从而降低通信的可靠性。
为了解决现有技术存在的问题，图1本发明实施例提供一种确定驻留小区的方法的流程图，该方法的执行主体为用户设备UE，如图1所示，该方法具体包括如下流程：
S101：用户设备UE判断是否要进行重选小区；
S102：若否，则UE获取驻留小区的参数信息和至少一个非驻留小区的参数信息；
具体地，对S101和S102进行解释：UE采用标准H或者标准R判断是否要进行重选小区，其中，重选小区的方法与现有技术相同，在此不再赘述。当UE判断不满足重选小区的条件之后，UE获取驻留小区的参数信息和至少一个非驻留小区的参数信息，该参数信息可以是参考信号接收功率(Reference Signal Receiving Power，简称RSRP)或参考信号接收质量(ReferenceSignalReceivingQuality，简称RSRQ)。
S103：UE根据驻留小区的参数信息与任一个非驻留小区的参数信息判断是否满足预设条件；其中，该预设条件用于确保非驻留小区的参数信息大于驻留小区的参数信息；
具体地，该预设条件包括：驻留小区的参数信息小于第一门限值，所述非驻留小区的参数信息大于第二门限值；和/或，，非驻留小区的参数信息与驻留小区的参数信息的差值大于第三门限值。其中，该预设条件可以嵌入至第三代合作伙伴计划(3rd Generation Partnership Project，简称3GPP)304中小区选择/重选过程中，即可以携带在该过程中的任一消息中，或者该预设条件可以是基站通过广播消息、寻呼消息、释放消息或者切换消息等发送给UE的；本发明实施例对该预设条件的获取方法不做限制。需要说明的是，非驻 留小区即为UE在该非驻留小区的覆盖范围内，但是UE并没有在该小区中驻留。
S104：若是，则UE将对应的非驻留小区作为候选小区；
S105：UE在至少一个候选小区中选择对应参数信息最大的小区为新的驻留小区或者选择任一个候选小区为新的驻留小区。
结合S104和S105，比如：参数信息为RSRQ，UE的驻留小区为A，非驻留小区为B、C和D。UE确定驻留小区A的RSRQ小于第一门限值，并且UE确定非驻留小区B和C的RSRQ都大于第二门限值，因此，UE将非驻留小区B和C作为候选小区，最后，UE随机选择B或者C作为新的驻留小区，或者，UE比较B和C的RSRQ，选择较大者对应的小区为新的驻留小区。
本发明实施例提供一种确定驻留小区的方法，包括：用户设备UE判断是否要进行重选小区；若否，则UE获取驻留小区的参数信息和至少一个非驻留小区的参数信息；UE根据驻留小区的参数信息与任一个非驻留小区的参数信息判断是否满足预设条件；若是，则UE将对应的非驻留小区作为候选小区；UE在至少一个所述候选小区中选择对应参数信息最大的小区为新的驻留小区或者选择任一个所述候选小区为新的驻留小区；其中，该预设条件用于确保非驻留小区的参数信息大于驻留小区的参数信息。从而使得UE能够在不满足重选小区的前提下，还能够在驻留小区和非驻留小区中选择较好的小区来驻留，更新后的驻留小区相比较于更新前的驻留小区具有较低的脱网率和呼损率，进而保证通信的可靠性。
图2为本发明一实施例提供的一种确定驻留小区的方法的交互流程图，该方法涉及的网元包括：UE和网络设备，需要说明的是，这里的网络设备可以是基站或者运营支撑系统(Operational Support System，简称OSS)设备。该方法与图1对应方法的区别在于：UE判断驻留小区的参数信息与任一个所述非驻留小区的参数信息满足预设条件之后，UE向网络设备发送指示消息，以使得网络设备根据指示消息对驻留小区进行优化，图3为UE、基站和OSS设备的关系示意图，如图3所示，当网络设备为OSS设备时，UE通过基站与OSS设备进行交互，下面具体介绍确定驻留小区的方法，如图2所示，该方法包括：
S201：用户设备UE判断是否要进行重选小区；
S202：若否，则UE获取驻留小区的参数信息和至少一个非驻留小区的参数信息；
S203：UE根据驻留小区的参数信息与任一个非驻留小区的参数信息判断是否满足预设条件，其中，该预设条件用于确保所述非驻留小区的参数信息大于所述驻留小区的参数信息；
具体地，步骤S201-S203与步骤S101-S103过程相同，在此不再赘述。
S204：若是，则UE向网络设备发送指示消息，该指示消息用于指示驻留小区为差驻留小区或者指示消息用于指示UE为差驻留小区的次数，以使网络设备对驻留小区进行射频(Radio Frequency，简称RF)优化或者对驻留小区的重选参数进行优化；
S205：UE驻留在优化后的驻留小区中。
结合S204和S205，只要UE不满足重选条件，同时还满足上述预设条件，那么UE即为差驻留小区。一种情况：指示消息用于指示驻留小区为差驻留小区；另一种情况：由于UE可能是在不断的移动过程中，因此，它所在的驻留小区可能在一段时间内为差驻留小区，另一段时间内又不是差驻留小区，UE可以在一个预设周期内统计驻留小区为差驻留小区的次数，并将该次数发送给网络设备，以使网络设备对驻留小区进行射频RF优化或者对驻留小区的重选参数进行优化。需要说明的是，上述的指示消息可以是无线资源控制协议(Radio Resource Control，简称RRC)建立请求消息，或者最小化路测(Minimum Driver Test，简称MDT)消息、或者位置区码(Location Area Code，简称LAC)更新消息等。
一种可选方式，RF优化的目的是在优化网络覆盖的同时保证良好的接收质量，同时网络具备正确的邻区关系，从而保证下一步业务优化时无线信号的分布是正常的，为优化工作打下良好的基础。具体地，RF优化可以包括：调整驻留小区的天线下发功率、方向角和下倾角等方式。比如：可以增加天线下发功率，调整方向角或者是增大下倾角等来改变驻留小区的覆盖质量。具体可以采用现有技术中所提供的RF优化方法，本发明对该优化方法不做限制。
另一种可选方式，网络设备可以优化驻留小区的重选参数，比如：频率 优先级、重选小区门限等，优化频率优先级可以通过加大或者减小频率优先级来实现，优化重选小区门限可以通过该减小或者增大小区重选门限来实现，从而达到UE可以选择到更好强度/质量的小区作为驻留小区。比如，重选参数需要重选小区门限可能要大于-105dBm，而目标小区信号质量为-106dBm，驻留小区质量为-125dBm，则当前UE不能到达目标小区。这种情况下可以修改重选门限为-106dBm，这样就可以到目标小区而不必停留在上述驻留小区了。通常可以将优化重选参数的方式和UE自身选择较好的驻留小区的方式称为无线资源管理(Radio Resource Management，简称RRM)优化。
本发明实施例提供一种确定驻留小区的方法，其中UE向网络设备发送指示消息，以使得网络设备可以对驻留小区进行RF优化或者对驻留小区的重选参数，进而保证UE可以在一个RSRP或者RSRQ较好的小区驻留，提高通信的可靠性。
图4为本发明另一实施例提供的一种确定驻留小区的方法的交互流程图，该方法涉及的网元包括：UE和网络设备，该网络设备为基站或者OSS设备。其中该方法与图1对应的方法区别在于：该方法是网络设备根据驻留小区的参数信息与任一个非驻留小区的参数信息判断是否满足预设条件，最后网络设备对驻留小区进行优化。如图4，该方法具体包括如下流程：
S401：网络设备接收用户设备UE发送的第一指示消息，该第一指示消息用于指示UE不满足重选小区的条件；
其中，UE根据H标准或者R标准判断是否满足重选小区的条件。
S402：网络设备获取UE的测量数据，该测量数据包括：UE的驻留小区的参数信息和至少一个非驻留小区的参数信息；
其中，该测量数据可以是MDT数据或者是测量报告(Measurement Report，简称MR)数据，所述参数信息包括：参考信号接收功率RSRP或参考信号接收质量RSRQ。
S403：网络设备根据驻留小区的参数信息与任一个非驻留小区的参数信息判断是否满足预设条件，其中，该预设条件用于确保非驻留小区的参数信息大于驻留小区的参数信息；
具体地，所述预设条件包括：所述驻留小区的参数信息小于第一门限值，所述非驻留小区的参数信息大于第二门限值；和/或，所述非驻留小区的参数 信息与所述驻留小区的参数信息的差值大于第三门限值。
S404：若是，则网络设备对驻留小区进行射频RF优化或者对驻留小区的重选参数进行优化，以使UE驻留在优化后的驻留小区中。
其中，其中网络设备对驻留小区进行射频RF优化或者对驻留小区的重选参数进行优化与S204中的优化方法相同，在此不再赘述。
本发明实施例提供一种确定驻留小区的方法，其中UE向网络设备发送指示消息，以使得网络设备可以对驻留小区进行RF优化或者对驻留小区的重选参数，进而保证UE可以在一个RSRP或者RSRQ较好的小区驻留，提高通信的可靠性。
图5为本发明再一实施例提供的一种确定驻留小区的方法的交互流程图，该方法涉及的网元包括：UE和网络设备，该网络设备为基站或者OSS设备。其中该方法与图1对应的方法区别在于：该方法是网络设备根据驻留小区的参数信息与任一个非驻留小区的参数信息判断是否满足预设条件。如图5，该方法具体包括如下流程：
S501：网络设备接收用户设备UE发送的第一指示消息，该第一指示消息用于指示UE不满足重选小区的条件；
S502：网络设备获取UE的测量报告测量数据，该测量报告测量数据包括：UE的驻留小区的参数信息和至少一个非驻留小区的参数信息；
S503：网络设备根据驻留小区的参数信息与任一个非驻留小区的参数信息判断是否满足预设条件，其中，该预设条件用于确保非驻留小区的参数信息大于驻留小区的参数信息；
S504：若是，则所述网络设备向所述UE发送第二指示消息，所述第二指示消息用于指示所述UE将对应的非驻留小区作为候选小区，以使所述UE在至少一个所述候选小区中选择对应参数信息最大的小区为新的驻留小区或者选择任一个所述候选小区为新的驻留小区。
具体地，S501-S503和步骤S401-S403相同，在此不再赘述，S504步骤中所谓的对应的非驻留小区即为满足预设条件的非驻留小区，最后，UE在候选小区中选择对应参数信息最大的小区为新的驻留小区或者选择任一个所述候选小区为新的驻留小区。
进一步地，UE还可以通知网络设备自己的驻留小区为差驻留小区或者差 驻留小区的次数、或者重选小区的次数等信息，以使得网络设备根据这些信息对各个小区的负载进行优化或者对驻留小区进行优化等。具体地，图6为本发明提供的MDT增强机制的示意图，如图6所示，该机制包括：
S601：判断UE是否满足重选小区条件；若是，则执行步骤S602；若否，则执行步骤S605：
S602：则UE记录重选次数、当前驻留小区的制式、频点、全球小区标识(Global Cell identifier，简称GCI)或者空口识别小区标识，比如，LTE小区标识：物理小区标识(Physical Cell Indentifier，简称PCI)以及小区的RSRP或者RSRQ等可测量到的信息；以及重选小区的制式、频点、GCI或者PCI以及小区的RSRP或者RSRQ等可测量到的信息；
S603：网络设备根据S602得到的各个UE的记录信息获得要进行重选小区的UE个数或者比例等信息；
S604：网络设备根据UE个数或者比例等信息对各个小区进行负载优化；
S605：UE根据驻留小区的参数信息与任一个非驻留小区的参数信息判断是否满足预设条件；若是，则执行S606；若否，则执行S609；
S606：则UE记录差驻留小区的次数、RSRP或者RSRQ；
S607：网络设备根据S606得到的各个UE的记录信息获得差驻留小区对应的UE个数或者比例等信息；
S608：网络设备根据UE个数或者比例等信息进行RF优化或者RRM优化；
S609：UE记录不满足预设条件的小区标识、小区频点、RSRP或者RSRQ；
S610：网络设备根据S609得到的各个UE的记录信息获得不满足预设条件的UE个数或者比例等信息；
S611：网络设备优化不满足预设条件的UE比例。
该MDT机制包括：网络设备根据差驻留小区或者差驻留小区的次数、或者重选小区的次数等信息，来对各个小区的负载进行优化或者对驻留小区进行优化等，从而提高通信可靠性。
