Abstract

一种必要系统信息获取失败时的处理方法及装置。所述方法应用于终端设备侧，所述方法包括：在终端设备进行小区重选评估的过程中，或者，在终端设备应用系统信息获取过程中，当所述终端设备在一个非授权的频率上的至少一个小区无法获取必要系统信息时，所述终端设备认为在预定义的第一时间内，在所述频率上的所有小区被禁止，或者，在预定义的第一时间内，所述频率是最低优先级的频率。

Description

必要系统信息获取失败时的处理方法及装置 技术领域
本发明涉及通信领域。
背景技术
在新无线(NR，New Radio)系统中，终端设备应用系统信息获取过程以获取AS(access，接入)和NAS(non-access，非接入)信息，该过程适用于空闲态、非连接态和连接态的终端设备。
当终端设备进行小区选择时(例如开机时)、小区重选时、从无覆盖返回时、同步重配完成后、从另一个RAT(radio access technology，无线接入技术)进入网络后、收到系统信息改变的指示时、收到PWS(Public Warning System，公共预警系统)通知时以及一旦终端没有有效版本的存储的系统信息块(System Information Block，SIB)，终端设备将会应用系统信息获取过程。
图1是NR中的系统信息获取过程的一示意图。如图1所示，网络设备向终端设备发送主信息块(Master Information Block，MIB)，还可以发送SIB1(System Information Block Type1)，另外，也可以是终端设备向网络设备发送系统信息请求(System Information Request)，网络设备再向终端设备发送系统信息消息(System Information Messages)。
当终端设备处于空闲态或非激活态或连接态下定时器T311正运行时，当终端设备在一个小区无法获得MIB时，则终端设备将会将该小区看作禁止且MIB中的intraFreqReselection当作设置为允许执行禁止；当终端设备获得了MIB而无法获得SIB1时，终端设备将会将该小区看作禁止；当MIB中的intraFreqReselection设置为不允许，终端设备将会认为与禁止小区相同频率上的其他小区的小区重选是不允许的；当MIB中的intraFreqReselection设置为允许时，终端设备将会认为与禁止小区相同频率上的其他小区的小区重选是允许的。
应该注意，上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
频率资源问题是通信技术讨论中重要的课题之一。为了解决频率资源问题，除了提高资源利用率，3GPP也尝试使用更多的频带，包括未授权频段的使用，例如基于NR在非授权频段上的接入机制(NR based access to unlicensed spectrum,NR-U)。
在NR-U里，由于网络设备和/或终端设备在进行通信前，需要进行信道监听，即通过先听后说(Listen Before Talk，LBT)和/或空闲信道评估(Clear Channel Assessment，CCA)机制，确定信道是否空闲。当信道空闲时，网络设备进行下行传输，例如传输MIB和/或SIB1等。
但是，发明人发现，在NR-U里，由于LBT和/或CCA，在网络设备监听到信道忙碌的情况下，下行传输不能进行，这样网络设备可能无法传输MIB和/或SIB1，在这种情况下终端设备无法获得MIB/SIB1。并且，在相同频率的所有小区很可能都无法传输MIB和/或SIB1。而按照NR的准则，当终端设备在一个小区无法获取MIB时，该小区被禁300秒(s)；当终端设备获取了MIB而无法获取SIB1时，取决于MIB里的intraFreqReselection，该小区或该小区所在频率被禁300秒。这意味着终端设备可能一直在相同频率的小区里尝试获取MIB和/或SIB1，但由于该频率处于忙碌的状态，终端设备将会一直无法获得MIB和/或SIB1。这会导致终端设备耗电增加，并且终端设备驻留到服务小区的时间过长。
为了解决上述问题中的一个或多个，本发明实施例提供了一种必要系统信息获取失败时的处理方法及装置。

根据本发明实施例的第七方面，提供了一种用于必要系统信息获取的参数配置方法，所述方法应用于网络设备侧，所述方法包括：向终端设备配置作为至少一个小区的小区数量的第一数量，或者，向终端设备配置用于确定所述第一数量的第二数量，以使得终端设备在进行小区重选评估的过程中，或者，在应用系统信息获取过程中，当所述终端设备在一个非授权的频率上的至少一个小区无法获取必要系统信息时，所述终端设备认为在预定义的第一时间内，在所述频率上的所有小区被禁止，或者，在预定义的第一时间内，所述频率是最低优先级的频率。

根据本发明实施例的第十一方面，提供一种存储有计算机可读程序的存储介质，其中所述计算机可读程序使得用于必要系统信息获取的参数配置装置或网络设备执行本发明实施例的第七方面所述的用于必要系统信息获取的参数配置方法。

在本实施例中，例如，在终端设备进行小区选择(例如开机)、小区重选、从无覆盖返回、同步重配完成后、从另一个RAT进入网络后、收到系统信息改变的指示、收到PWS通知以及一旦终端设备没有有效版本的存储的SIB中的至少一个的情况下，终端设备将会应用系统信息获取过程。
在本实施例中，在一个非授权的频率上的至少一个小区也可以称为至少一个非授权小区，“非授权”例如是指NR-U；另外，“对于NR-U”可以是指“当该小区是NR-U小区时”，或者，“对于NR-U”也可以是指“当该频率是NR-U频率”。
在步骤301中，当该终端设备在一个非授权的频率上的至少一个小区无法获取必要系统信息时，该终端设备进行适当的处理，对于该终端设备进行检查而确定法获取必要系统信息的小区数量，也就是至少一个小区的小区数量，本发明实施例不进行限制。
在本实施例中，例如，该至少一个小区的小区数量是第一数量，该第一数量可以是由网络设备配置的、预定义的或者由终端设备确定的。
例如，网络设备配置的第一数量为2，该终端设备在一个非授权频率上的小区中检查是否能够获取必要系统信息时，在该频率上的2个小区中进行检查，如果在该频率上的2个小区都无法获取必要系统信息，则进行步骤301中的处理。
在本实施例中，又例如，该至少一个小区的小区数量是第一数量，该第一数量大于或等于第二数量，该第二数量为大于或等于1的整数，该第二数量可以是由网络设备配置的、预定义的或者由终端设备确定的。
例如，网络设备配置的第二数量为2，该终端设备在一个非授权频率上的小区中检查是否能够获取必要系统信息时，可以在该频率上的大于等于2的数量的小区中进行检查，例如，在该频率上的3个小区中进行检查，如果在该频率上的3个小区都无 法获取必要系统信息，则进行步骤301中的处理。
在步骤301中，例如，根据小区数量是1个还是多个(即至少2个)，以及处理方式是该终端设备认为在预定义的第一时间内，在该频率上的所有小区被禁止，还是该终端设备认为在预定义的第一时间内，该频率是最低优先级的频率，组合为不同的方案。
例如，当该终端设备在一个非授权的频率上的一个小区无法获取必要系统信息时，该终端设备认为在预定义的第一时间内，在该频率上的所有小区被禁止；
又例如，当该终端设备在一个非授权的频率上的一个小区无法获取必要系统信息时，该终端设备认为在预定义的第一时间内，该频率是最低优先级的频率；
又例如，当该终端设备在一个非授权的频率上的至少2个小区无法获取必要系统信息时，该终端设备认为在预定义的第一时间内，在该频率上的所有小区被禁止；
又例如，当该终端设备在一个非授权的频率上的至少2个小区无法获取必要系统信息时，该终端设备认为在预定义的第一时间内，该频率是最低优先级的频率。
在本实施例中，该必要系统信息可以包括传输所必要的各种系统信息，例如，包括MIB和SIB1中的至少一个。
在本实施例中，该第一时间是预定义的，例如，该第一时间小于或等于第一阈值，该第一阈值例如是300秒。
例如，该第一时间是300秒，或100秒，或50秒，或10秒。
在本实施例中，例如，小区被禁止可以是指示小区状态“被禁止”或当作小区状态是“被禁止”，该小区被禁止的行为例如是：该小区不是小区选择或重选的候选，也就是说，排除该小区作为选择或重选的候选。
在本实施例中，对于无法获取作为该必要系统信息的MIB和SIB1，可以采用相同或不同的解决方案，也就是说，对于作为该必要系统信息的MIB和SIB1，该至少一个小区的小区数量可以相同或不同，和/或，该终端设备可以采用在该频率上的所有小区被禁止和该频率是最低优先级的频率中的相同或不同的处理方式。
例如，当该终端设备在一个非授权的频率上的N个小区无法获取MIB时，该终端设备认为在预定义的第一时间内，在该频率上的所有小区被禁止；和/或，当该终端设备在一个非授权的频率上的N个小区无法获取SIB1时，该终端设备认为在预定义的第一时间内，在该频率上的所有小区被禁止，N为大于或等于1的整数。
例如，当该终端设备在一个非授权的频率上的N个小区无法获取MIB时，该终端设备认为在预定义的第一时间内，在该频率上的所有小区被禁止；和/或，当该终端设备在一个非授权的频率上的M个小区无法获取SIB1时，该终端设备认为在预定义的第一时间内，在该频率上的所有小区被禁止。
例如，当该终端设备在一个非授权的频率上的N个小区无法获取MIB时，该终端设备认为在预定义的第一时间内，在该频率上的所有小区被禁止；和/或，当该终端设备在一个非授权的频率上的N个小区无法获取SIB1时，该终端设备认为在预定义的第一时间内，该频率是最低优先级的频率，N为大于或等于1的整数。
例如，当该终端设备在一个非授权的频率上的N个小区无法获取MIB时，该终端设备认为在预定义的第一时间内，在该频率上的所有小区被禁止；和/或，当该终端设备在一个非授权的频率上的M个小区无法获取SIB1时，该终端设备认为在预定义的第一时间内，该频率是最低优先级的频率，N和M是不同的正整数。
例如，当该终端设备在一个非授权的频率上的N个小区无法获取MIB时，该终端设备认为在预定义的第一时间内，该频率是最低优先级的频率；和/或，当该终端设备在一个非授权的频率上的N个小区无法获取SIB1时，该终端设备认为在预定义的第一时间内，在该频率上的所有小区被禁止，N为大于或等于1的整数。
例如，当该终端设备在一个非授权的频率上的N个小区无法获取MIB时，该终端设备认为在预定义的第一时间内，该频率是最低优先级的频率；和/或，当该终端设备在一个非授权的频率上的M个小区无法获取SIB1时，该终端设备认为在预定义的第一时间内，在该频率上的所有小区被禁止。
例如，当该终端设备在一个非授权的频率上的N个小区无法获取MIB时，该终端设备认为在预定义的第一时间内，该频率是最低优先级的频率；和/或，当该终端设备在一个非授权的频率上的N个小区无法获取SIB1时，该终端设备认为在预定义的第一时间内，该频率是最低优先级的频率，N为大于或等于1的整数。
例如，当该终端设备在一个非授权的频率上的N个小区无法获取MIB时，该终端设备认为在预定义的第一时间内，该频率是最低优先级的频率；和/或，当该终端设备在一个非授权的频率上的M个小区无法获取SIB1时，该终端设备认为在预定义的第一时间内，该频率是最低优先级的频率，N和M是不同的正整数。
以下，针对各种可能的情况进行示例性的说明。
示例1)当该终端设备在一个非授权的频率上的至少一个小区无法获取MIB和SIB1中的至少一个时，该终端设备认为与该至少一个小区在相同频率上的其他小区在该第一时间内不是小区选择或重选的候选。
对于至少一个小区的小区数量为1的情况，例如，对于NR-U，当终端设备已经发现无法获取MIB和SIB1中的至少一个时，终端设备可以或者将会认为该小区相同频率上的其他小区在最多300秒内不是小区选择或重选的候选。
对于至少一个小区的小区数量为多个，即至少2个的情况，例如，对于NR-U，当终端设备已经发现一个频率上至少2个小区无法获取MIB和SIB1中的至少一个时，终端设备可以或将会认为该至少2个小区相同频率上的其他小区在最多300秒内不是小区选择或重选的候选。

例如，当指示小区状态“被禁止”或当作小区状态是“被禁止”处理时，(1)当一个小区由于无法获得MIB、当作小区状态是“被禁止”来处理、且该小区是NR-U小区时，终端设备可以或将会排除该小区作为小区选择或重选的候选最多300秒，可以或将会排除相同频率上的其他小区作为小区选择或重选的候选最多300s；(2)否则，即获得了MIB时，当一个小区由于无法获得SIB1、当作小区状态是“被禁止”处理、且该小区是NR-U小区时，终端设备可以或将会排除该小区作为小区选择或重选的候选最多300秒，和/或，终端设备可以或将会排除相同频率上的其他小区作为小区选择或重选的候选最多300秒。上述处理(1)和(2)可以分别执行，也可以一起执行。

示例4)在该终端设备处于空闲态或非激活态或连接态下定时器T311正运行的情况下，当该终端设备在一个非授权的频率上的至少一个小区无法获取MIB时，该终端设备将该至少一个小区看作禁止且MIB中的intraFreqReselection当作设置为不允许执行禁止；和/或，在该终端设备处于空闲态或非激活态或连接态下定时器T311正运行的情况下，当该终端设备在一个非授权的频率上的至少一个小区获取了MIB而无法获取SIB1时，终端设备将该至少一个小区看作禁止且MIB中的intraFreqReselection当作设置为不允许执行禁止。
对于至少一个小区的小区数量为1的情况，例如，对于NR-U，当终端设备处于空闲态或非激活态或连接态下定时器T311正运行时，(1)当终端设备在一个小区无法获得MIB时，则终端设备可以或将会将该小区看作禁止且intraFreqReselection当作设置为不允许执行禁止；(2)当终端设备在一个小区获取了MIB而无法获得SIB1 时，终端设备可以或将会将该小区看作禁止；且终端设备可以或将会将该小区看作禁止且intraFreqReselection当作设置为不允许执行禁止，而不管MIB里的intraFreqReselection的实际值。上述处理(1)和(2)可以分别执行，也可以一起执行。

示例5)当该终端设备在一个非授权的频率上的至少一个小区无法获取MIB和SIB1中的至少一个时，该终端设备认为该至少一个小区所在的该频率在该第一时间内的优先级最低。
对于至少一个小区的小区数量为1的情况，例如，对于NR-U，当终端设备已经发现在一个小区无法获得MIB和SIB1中的至少一个时，终端设备可以或将会认为该小区所在频率在最多300秒内优先级最低。
对于至少一个小区的小区数量为多个，即至少2个的情况，例如，对于NR-U，当终端设备已经发现在一个频率上的至少2个小区无法获得MIB和SIB1中的至少一个时，终端设备可以或将会认为该小区所在频率在最多300秒内优先级最低。
示例6)当指示小区状态“被禁止”或当作小区状态是“被禁止”处理时，当在一个小区由于无法获得MIB、当作小区状态是“被禁止”来处理，且该小区是NR-U小区时当所述终端设备在一个非授权的频率上的一个小区无法获取MIB时，所述终端设备在所述第一时间内排除认为所述小区作为在所述第一时间内不是小区选择或重选的候选，或者，认为所述小区所在的所述频率在所述第一时间内的优先级最低；和/或，当指示小区状态“被禁止”或当作小区状态是“被禁止”处理时，当获得了MIB时，当在一个小区由于无法获得SIB1、当作小区状态是“被禁止”处理，且该小区是NR-U小区时所述终端设备在一个非授权的频率上的一个小区获取了MIB而 无法获取SIB1时，所述终端设备在所述第一时间内排除认为所述小区在所述第一时间内不是作为小区选择或重选的候选，或者，认为所述小区所在的所述频率在所述第一时间内的优先级最低。

实施例2
本发明实施例提供了一种用于必要系统信息获取的参数配置方法，该方法应用于网络设备侧，其对应于实施例1所述的应用于终端设备侧的必要系统信息获取失败时的处理方法，相同的内容不再重复说明。

在本实施例中，网络设备可以使用广播方式和/或专用方式配置参数，例如，上述第一数量或第二数量。
例如，在使用广播方式配置时，可以作为同频或异频公共的参数，包括在SIB2里；或者，作为频率特定的参数，同频包括在SIB3、异频包括在SIB4中。
例如，在使用专用方式配置时，可以由RRCReconfiguration消息传递，例如包括在IE UE-TimersAndConstants里。
例如，当广播方式和专用方式都支持时，可以在未收到专用方式配置的参数前使用广播方式配置的参数，一旦收到专用方式配置的参数则应用专用方式配置的参数；当终端设备离开连接状态或进入空闲态或进入非激活态时，终端设备使用专用方式，直到：1)重选到其他小区；或2)定时器T3xx超时，T3xx可以重用LTE里T350，也可以定义新的定时器。当T3xx是新定时器时，那么当终端设备离开连接状态或进入空闲态或进入非激活态时，启动该定时器；进入连接态或小区重选时停止该定时器。
在本实施例中，如图4所示，该方法还可以包括：
步骤402：网络设备在一个非授权频率上进行信道监听；
在步骤402中，网络设备例如通过LBT和/或CCA进行信道监听，且在监听到信道忙碌的情况下，不进行下行传输，即不发送系统信息。
在本实施例中，步骤401和步骤402之间没有时序关系，即，在执行步骤401和步骤402时不对各个步骤的先后顺序进行限制。
由上述实施例可知，在终端设备进行小区重选评估的过程中，或者，在终端设备应用系统信息获取过程中，当终端设备在一个非授权的频率上的至少一个小区无法获取必要系统信息时，该终端设备认为在预定义的第一时间内，在该频率上的所有小区被禁止，或者，在预定义的第一时间内，该频率是最低优先级的频率。这样，终端设备能够避免在相同的非授权频率上一直尝试获取必要系统信息，从而节省终端设备的耗电并尽快找到合适小区进行驻留。

在步骤502中，网络设备例如通过LBT和/或CCA进行信道监听，且在监听到信道忙碌的情况下，不进行下行传输，即不发送系统信息。
在本实施例中，步骤501至步骤504之间没有时序关系，即，在执行步骤501至步骤504时不对各个步骤的先后顺序进行限制。
在本实施例中，步骤501至步骤504的具体实施可以参照实施例1和实施例2的记载，此处不再重复说明。
由上述实施例可知，在终端设备进行小区重选评估的过程中，或者，在终端设备应用系统信息获取过程中，当终端设备在一个非授权的频率上的至少一个小区无法获取必要系统信息时，该终端设备认为在预定义的第一时间内，在该频率上的所有小区被禁止，或者，在预定义的第一时间内，该频率是最低优先级的频率。这样，终端设备能够避免在相同的非授权频率上一直尝试获取必要系统信息，从而节省终端设备的耗电并尽快找到合适小区进行驻留。
