Description

选择驻留小区的方法和装置 技术领域
本发明实施例涉及通信领域，并且更具体地，涉及选择驻留小区的方法和装置。
背景技术
目前，无线蜂窝***中开始考虑通过使用免许可(Unlicensed)频段(如2.4GHz、5.8GHz)扩展蜂窝***的使用频率，主要手段包括授权辅助接入(License Assisted Access，简称为“LAA”)与长期演进(Long Term Evolution，简称为“LTA”)/无线保真(Wireless Fidelity，简称为“WiFi”)聚合两种。这两种聚合手段的主要特点包括：(1)聚合资源属于免许可频段，仅作为普通许可频段的辅助频段使用；(2)免许可频段的使用不仅受限于基站调度，也受限于该频段的负载，即需要经过竞争机制才能够使用。因此与许可频段相比，终端的接入时间要求越短越好，这样才能在有限的时间里充分利用免许可频段资源，提高资源利用率。
在现有阶段，免许可频段还仅是作为许可频段的补充存在，例如LAA技术中免许可频段尽管可以采用LTE的工作方式，但是只能作为许可频段的辅载波存在。未来LAA可以像WLAN一样采用独立工作方式，此时终端在无数据连接的空闲态时可以驻留在使用许可频段的小区，也可以驻留在使用免许可频段的小区，但由于免许可频段小区接入需要使用先听后讲(Listen Before Talk，简称为“LBT”)机制对无线信道进行侦听和检测，并在竞争到之后需要向WLAN一样在传输一段时间后回到侦听状态继续侦听并竞争信道，因此无法像许可频段小区一样保证终端接入的时延、丢包率等性能。然而免许可频段也有频段资源丰富，带宽较宽等优势，终端可以灵活选择信道条件较好的免许可频段信道进行接入。因此如何使终端设备灵活的驻留在许可频段小区和免许可频段小区是目前需要解决的问题。
发明内容
本发明实施例提供一种选择驻留小区的方法和装置，使得终端设备可以驻留在许可频段小区或免许可频段小区中，并能在许可频段与免许可频段之间获得最佳的接入性能。

第二方面，提供了一种选择驻留小区的方法，包括：网络设备向终端设备发送配置信息，以便于所述终端设备根据所述配置信息对许可频段和免许可频段进行测量，以及根据对所述许可频段和所述免许可频段进行测量的测量结果，确定驻留小区；其中，所述配置信息包括信道信号质量测量信息和/或信道干扰水平测量信息，其中，所述信道质量测量信息包括参考信号接收功率RSRP参数和/或参考信号接收质量RSRQ参数，所述信道干扰水平测量信息包括接收信号强度指示RSSI参数。
第三方面，提供了一种终端设备，包括：测量模块，用于根据配置信息对许可频段和免许可频段进行测量，所述配置信息包括信道信号质量测量信息和/或信道干扰水平测量信息，其中，所述信道质量测量信息包括参考信号接收功率RSRP参数和/或参考信号接收质量RSRQ参数，所述信道干扰水平测量信息包括接收信号强度指示RSSI参数；确定模块，用于根据所述测量模块对所述许可频段和所述免许可频段进行测量的测量结果，确定驻留小区。
第四方面，提供了一种网络设备，包括：发送模块，用于向终端设备发送配置信息，以便于所述终端设备根据所述配置信息对许可频段和免许可频段进行测量，以及根据对所述许可频段和所述免许可频段进行测量的测量结果，确定驻留小区；其中，所述配置信息包括信道信号质量测量信息和/或信道干扰水平测量信息，其中，所述信道质量测量信息包括参考信号接收功率RSRP参数和/或参考信号接收质量RSRQ参数，所述信道干扰水平测量信息包括接收信号强度指示RSSI参数。

图1是根据本发明实施例的选择驻留小区的方法的示意性流程图，如图1所示，方法100包括：
S110，终端设备根据配置信息对许可频段和免许可频段进行测量，所述配置信息包括信道信号质量测量信息和/或信道干扰水平测量信息，其中，所述信道质量测量信息包括参考信号接收功率RSRP参数和/或参考信号接收质量RSRQ参数，所述信道干扰水平测量信息包括接收信号强度指示RSSI参数；
S120，所述终端设备根据对所述许可频段和所述免许可频段进行测量的测量结果，确定驻留小区。
因此，本发明实施例中，终端设备可以根据配置信息对许可频段和免许可频段进行测量，并根据测量的结果选择驻留小区，由此，终端设备可以驻留在许可频段小区或免许可频段小区中，并能在许可频段与免许可频段之间获得最佳的接入性能。
需要说明的是，在本发明实施例中，许可频段小区指的是许可频段对应的小区，免许可频段小区指的是免许可频段对应的小区，对许可频段和免许可频段进行测量包括对许可频段和免许可频段的信道进行测量以及对许可频段小区和免许可频段小区进行测量。
在本发明实施例中，可选地，所述配置信息，可以是网络设备向终端设备发送的，所述配置信息还可以是终端设备自身具有的默认配置信息。本发明对此不作限定。
可选地，如图2所示，所述方法100还包括：
S130，所述终端设备接收网络设备发送的所述配置信息。
可选地，所述终端设备可以接收网络设备发送的广播消息，所述广播消息包括所述配置信息，其中，所述广播消息可以是主信息快(Master Information Block，简称为“MIB”)携带的广播消息，或称为MIB消息。所述广播消息还可以为***信息块(System Information Block，简称为“SIB”)携带的广播消息，或称为SIB消息，所述广播消息还可以是其他广播消息，本发明对此不作限定。
优选地，所述广播消息为SIB消息，例如可以是现有通信标准中的SIB4消息或SIB5消息，还可以是新引入的与现有技术中的SIB消息不同的新的SIB消息，例如可以命名为SIBX消息。具体地，网络设备可以通过在现有技术中的SIB4消息或SIB5消息中添加信息元(Information Element，简称为“IE”)的方式实现SIB4消息或SIB5消息中包括配置信息，还可以在新的SIB消息中包括与配置信息相对应的IE。
在本发明实施例中，可选地，所述配置信息还包括测量触发条件信息和/或测量窗口信息。
具体地，所述测量触发条件信息可以为测量周期，此时，终端设备可以按照测量周期进行许可频段和免许可频段的测量；所述触发条件信息还可以为触发测量的事件，例如，触发测量的事件可以为许可频段服务小区测量值低于门限值，或，免许可频段服务小区测量值低于门限值。
所述测量窗口信息指示每次测量的时间长度，所述测量窗口可以是一个固定的时间长度也可以为一个变化的时间长度，比如，如果终端设备在之前的测量结果情况比较明确，例如接收信号强度指示(Received Signal Strength Indicator，简称为“RSSI”)远高于或远低于门限值，终端设备可以使用较短 的测量窗口；若终端设备在之前的测量结果情况不好，即信道较为复杂，例如RSSI接近门限值，则测量窗口可以进行相应扩展。
在本发明实施例中，可选地，所述配置信息可以是由核心网配置，并通过非接入层(Non-access stratum，简称为“NAS”)信令下发给终端设备的。换句话说，所述终端设备接收核心网设备发送的非接入层NAS信令，所述NAS信令包括所述配置信息。
优选地，在S110中，所述配置信息还包括频段优先级信息，所述频段优先级信息用于指示不同的频段能够作为所述终端设备的驻留频段的顺序。
具体来说，频段优先级信息具体指示许可频段和免许可频段的优先级，以及免许可频段中各个免许可频段的优先级。
相应地，在所述频段优先级信息指示所述免许可频段的优先级高于所述许可频段的优先级时，S120具体为：在确定所述免许可频段中的第一免许可频段的RSSI值低于第一预设门限值，且所述第一免许可频段对应的免许可频段小区中的至少一个免许可频段小区的RSRP值和/或RSRQ值高于第二预设门限值时，将所述至少一个免许可频段小区中质量最好的免许可频段小区确定为所述驻留小区。
也就是说，在配置了频段优先级且免许可频段优先级高于许可频段优先级时，按照以下流程和相应参数进行频段信道选择及小区重选：当终端测量的某一免许可频段RSSI质量，包括RSSI均值及RSSI发生概率等信息，低于门限值A1，且该频率至少有一个小区的参考信号功率(Reference Signal Receiving Power，简称为“RSRP”)/参考信号质量(Reference Signal Receiving Quality，简称为“RSRQ”)值高于门限值B1；则判断终端设备可以选择该频段该小区进行驻留，否则终端设备不能选择该频段进行驻留，如果该免许可频段对应的小区中只有一个小区的RSRP/RSRQ值高于门限值B1，则将该小区确定为驻留小区，如果该免许可频段对应的小区中有多个小区的RSRP/RSRQ值高于门限值B1，则可以将该多个小区中的任意一个小区确定为驻留小区，优选地，将该多个小区中质量最好的小区确定为驻留小区。
可选地，在所述频段优先级信息指示所述免许可频段的优先级低于所述许可频段的优先级时，S120具体为：在确定所述许可频段对应的许可频段小区的RSRP值和/或RSRQ值低于第三预设门限值，且所述免许可频段中的第二免许可频段的RSSI值低于第四预设门限值，且所述第二免许可频段 对应的免许可频段小区中的至少一个免许可频段小区的RSRP值和/或RSRQ值高于第五预设门限值时，将所述至少一个免许可频段小区中质量最好的免许可频段小区确定为所述驻留小区。
也就是说，在配置了频段优先级，且免许可频段优先级低于许可频段优先级时，按照以下流程和相应参数进行频段信道选择及小区重选：在终端设备的许可频段中所有小区的RSRP/RSRQ值低于门限值C2，且当终端测量的某一免许可频段的RSSI质量，包括RSSI均值及RSSI发生概率等信息，低于门限值A2，且该免许可频段对应的小区中至少有一个小区的RSRP/RSRQ值高于门限值B2，则终端设备可以选择该频段该小区进行驻留，否则终端设备不能选择该频段进行驻留。如果该免许可频段对应的小区中只有一个小区的RSRP/RSRQ值高于门限值B2，则将该小区确定为驻留小区，如果该免许可频段对应的小区中有多个小区的RSRP/RSRQ值高于门限值B2，则可以将该多个小区中的任意一个小区确定为驻留小区，优选地，将该多个小区中质量最好的小区确定为驻留小区。
可选地，在所述频段优先级信息指示所述免许可频段的优先级等于所述许可频段的优先级时，S120具体为：在确定所述许可频段对应的许可频段小区的RSRP值和/或RSRQ值低于第六预设门限值，且所述免许可频段中的第三免许可频段的RSSI值低于第七预设门限值，且所述第三免许可频段对应的免许可频段小区中的至少一个免许可频段小区的RSRP值和/或RSRQ值高于第八预设门限值时，将所述至少一个免许可频段小区中质量最好的免许可频段小区确定为所述驻留小区。
换句话说，在配置了频段优先级，且免许可频段优先级等于许可频段优先级时，按照以下流程和相应参数进行频段信道选择及小区重选：在终端设备的许可频段中所有小区的RSRP/RSRQ值低于门限值C3，当终端测量的某一免许可频段的RSSI质量，包括RSSI均值及RSSI发生概率等信息，低于门限值A3，且该频段至少有一个小区的RSRP/RSRQ值高于门限值B3，则终端设备可以选择该频段该小区进行驻留，否则终端设备不能选择该频段进行驻留。如果该免许可频段对应的小区中只有一个小区的RSRP/RSRQ值高于门限值B3，则将该小区确定为驻留小区，如果该免许可频段对应的小区中有多个小区的RSRP/RSRQ值高于门限值B3，则可以将该多个小区中的任意一个小区确定为驻留小区，优选地，将该多个小区中质量最好的小区确定 为驻留小区。
可选地，在没有配置频段优先级时，S120具体为：在确定所述许可频段对应的许可频段小区的RSRP值和/或RSRQ值低于第九预设门限值，且所述免许可频段中的第四免许可频段的RSSI值低于第十预设门限值，且所述第四免许可频段对应的免许可频段小区中的至少一个免许可频段小区的RSRP值和/或RSRQ值高于第十一预设门限值时，将所述至少一个免许可频段小区中质量最好的免许可频段小区确定为所述驻留小区。
也就是说，在没有配置频段优先级时，可以根据上文中描述的配置了频段优先级，且免许可频段优先级低于许可频段优先级时的流程和相应参数进行频段信道选择及小区重选。
应理解，上文中提到的相关门限值，可以是根据实际经验设置的任意合理数值，本发明对此不作限定。并且，上文中的“第一”、“第二”等只是为了进行区分而不对其描述的参数构成限定。
需要说明的是，在本发明实施例中，可以根据小区的RSRQ判断小区质量的好坏，可以根据小区的RSRP判断小区质量的好坏，可以根据小区的干扰的大小判断小区质量的好坏，还可以根据以上参数的综合结果判断小区质量的好坏，本发明对此不作限定。
可选地，本发明实施例中的终端设备还可以根据在所有许可频段小区无法驻留的情况下才考虑驻留在免许可频段小区的重选规则进行驻留小区的选择，此时，可以通过调节门限值，调整终端设备接入免许可频段小区的概率。
在本发明实施例中，可选地，终端设备在对许可频段或免许可频段进行测量时，可以采用持续测量一段时间或者持续测量一定次数的方式进行，相应地，终端设备在根据测量结果进行小区重选时，可以根据测量结果在超过门限值的时间或者次数或者概率进行判断，本发明对此不作限定。
在本发明实施例中，可选地，所述配置信息还包括重选规则信息；
相应地，S120具体为：根据对所述许可频段和所述免许可频段进行测量的结果和所述重选规则信息，确定驻留小区。
可选地，所述重选规则信息包括免许可频段重选偏移量和重选门限值。并且，可以设置1个或多个免许可频段重选偏移量以及1个或多个重选门限值。
具体来说，免许可频段重选偏移量可以包括RSRQ/RSRQ的偏移量Qoffset和/或RSSI的偏移量Woffset，此时，终端设备在确定驻留小区时可以考虑加入Qoffset和/或Woffset，重选偏移量可以选取的值可以为：-3dB、-2dB、-1dB、0dB、1dB、2dB、3dB等，例如，在考虑Woffset时，终端设备可以按照以下流程确定驻留小区：在一段时间(timer)内或者满足一定次数(N)时，在免许可频段小区信号质量高于门限值1与Woffset的和，且许可频段小区信号质量低于门限值2，且免许可频段的RSSI满足占有率及信号强度均值要求时，可以选取该免许可频段对应的免许可频段小区作为驻留小区；或者，在一定timer条件下和/或满足一定次数(N)时，在免许可频段小区信号质量高于许可频段小区信号质量与Woffset的和，且许可频段小区信号质量低于门限值2，且免许可频段的RSSI满足占有率及信号强度均值要求时，可以选取该免许可频段对应的免许可频段小区作为驻留小区。
下面将结合具体实施例详细描述根据本发明实施例的选取驻留小区的方法，应注意，这些例子只是为了帮助本领域技术人员更好的理解本发明实施例，而并非限制本发明实施例的范围。
