Description

信息获取方法及装置 技术领域
本公开涉及通信领域，尤其涉及信息获取方法及装置。
背景技术
5G即NR(New Radio)网络相关标准化正在3GPP(3rd Generation Partnership Project，第三代合作伙伴计划)中进行。5G系统中，关键系统信息需要通过特定频带的高频波束按照预设调度周期，以扫描方式向基站信号覆盖范围内的各类型终端不停发送，而其他系统信息也采用同样的高频波束扫描方式向各类型终端不停发送。其中，所述关键系统信息是终端随机接入所述基站所需的最少的系统信息，所述其他系统信息是除了所述关键系统信息之外的其他的系统信息。
但是，如果采用上述方式发送其他系统信息，则对于MTC(Machine type communication，机器类型通信)终端而言，由于其自身的低移动性、时间可容忍性等特点，如果与移动终端一样不断监听基站通过波束扫描方式发送的其他系统信息，会造成资源浪费。

本公开实施例中，机器类型通信终端可以在监测到自身存在业务需 求，或监测到需要进行小区切换，即机器类型通信终端需要进行小区切换时，确定满足获取其他系统信息的触发条件。此时，机器类型通信终端会向基站发送获取请求，从而获得基站基于所述获取请求返回的所述其他系统信息。通过上述过程，机器类型通信终端可以在有业务需要或需要进行小区切换时才获取其他系统信息，无需在接收到关键系统信息后保持对其他系统信息的高频率的监听，避免浪费系统资源。

具体实施方式

本公开提供的技术方案适用于5G网络或者其它使用高频波束进行信息传输的网络通信系统。其中，上述高频波束是指频点在6GHz及以上频段的波束。本公开中涉及的执行主体包括：高频波束的发射端和接收端，其中，上述高频波束的发射端可以是设置有大规模天线阵列的基站。上述高频波束的接收端可以是MTC终端，例如智能电表、MTC监控、自动贩卖机等。在实现过程中，高频波束的发射端和接收端各自独立，同时又相互联系，共同实现本公开提供的技术方案。
本公开提供了一种信息获取方法，可以用于5G系统中的MTC终端。参照图1根据一示例性实施例示出的一种信息获取方法流程图，可以包括以下步骤：
在步骤101中，在接收到基站广播的关键系统信息后，检测是否满足获取其他系统信息的触发条件；
在步骤102中，在确定满足所述触发条件时，发送请求获取所述其他系统信息的获取请求到所述基站；
在步骤103中，接收所述基站基于所述获取请求定向发送的所述其他系统信息。
上述实施例中，MTC终端在接收到关键系统信息后，在满足获取其他系统信息的触发条件时，才请求获取所述其他系统信息，更适应于5G中波束扫描的场景，且提高了5G通信系统的效率。
针对上述步骤101，可选地，所述关键系统信息是终端随机接入基站 所需要的最少的系统信息，可以包括MIB(Master Information Block，主要信息块)，也就是说关键系统信息让各个类型的终端可以驻留并发起随机接入。所述其他系统信息是除了所述关键系统信息之外的其他的系统信息，可以包括SIB(System Information Block，系统信息块)。
相关技术中，MTC终端接收到关键系统信息之后，若在某一时刻需要获取其他系统信息，例如SIBn，则MTC终端会在该时刻向基站发送获取请求，同时开始监测基站发送的波束，等待获取SIBn。
本公开实施例中，为了节省系统资源，MTC终端在接收到所述关键系统信息后，自动检测是否满足获取其他系统信息的触发条件。可选地，所述触发条件包括以下条件中的任一个：
监测到有业务需求；
监测到需要进行小区切换。
其中，MTC终端的业务需求可以是由MTC终端自身发起的业务触发或者由其他终端发起的针对所述MTC终端的寻呼触发。例如，MTC终端在检测到自身的业务按键被触发时，确定自身有业务触发。当MTC终端接收到网络侧，例如所述基站转发的针对自身的寻呼请求时，确定存在寻呼触发。
另外，MTC终端虽然具有低移动性，但是一旦发生位置改变等情况，就可能需要进行小区切换。本公开实施例中，如果MTC终端检测到自身需要进行小区切换，则同样确定当前满足获取其他系统信息的触发条件。可选地，MTC终端可以在检测到自身接收到的当前小区的参考信号的强度值低于预设阈值时，确定需要进行小区切换。
本步骤中，MTC终端可以接收基站按照高频波束扫描方式发送的所述关键系统信息后，在检测到业务触发、寻呼触发或当前小区的参考信号的强度值低于预设阈值时，确定满足获取其他系统信息的触发条件。
针对上述步骤102，MTC终端在确定满足所述触发条件时，按照相关技术发送请求获取所述其他系统信息的获取请求到所述基站。
针对上述步骤103，所述基站会基于所述获取请求将所述其他系统信息发送给所述MTC终端，MTC终端直接接收即可。
相关技术中，信道互易性是指系统的上下行链路在相同的频率资源的不同时隙上传输，所以在相对较短的时间之内，可以认为上行链路和下行链路的传输信号所经历的信道衰落是相同的，这就是信道互易性。基于信道互易性，可通过基站的上行接收获得下行发送信号将要经历的信道衰落信息，很好地支持基站的波束赋形(智能天线)功能。波束赋形技术通过基站获取的上行信道信息调整下行信号发送过程中的天线阵列各单元的加权系数，产生具有指向性的波束，从而获得明显的阵列增益，在扩大覆盖范围、改善边缘吞吐量以及干扰抑制、干扰协调等方面都具有较大优势。
本公开实施例中，在MTC终端发送所述获取请求到基站的过程中，基站基于信道互易性，可以定向将所述其他系统信息发送给该MTC终端。
上述实施例中，机器类型通信终端可以在有业务需要或需要进行小区切换时才获取其他系统信息，无需在接收到关键系统信息后保持对其他系统信息的高频率的监听，避免浪费系统资源。
在一实施例中，基站可以为MTC终端配置一个较长的广播其他系统信息的目标周期时长，且该目标周期时长通过关键系统信息发送给MTC终端。可选地，所述目标周期时长超过所述基站广播系统信息块SIB中SIB1的周期时长。
相关技术中，MTC终端接收到关键系统信息，例如MIB后，就开始监听SIB1，SIB1中包括NAS(Network Attached Storage，网络附属存储))系统信息，终端在空闲态和连接态下所使用的定时器和常数信息，SIB1的周期时长是80毫秒。
本公开实施例中，基站为MTC终端配置的目标周期时长可以超过SIB1的周期时长，例如可以是关键系统信息的周期时长的若干倍，MIB的周期时长为40毫秒，目标周期时长如果为MIB周期时长的8倍，则为320毫秒。
相应地，触发条件可以包括以下条件中的任一个：
当前时间点与接收到所述关键系统信息的时间点之间的累计时长达到所述目标周期时长；
在所述累计时长小于所述目标周期时长时，监测到有业务需求；
在所述累计时长小于所述目标周期时长时，监测到需要进行小区切换。
即MTC终端在接收到关键系统信息后，可以根据其中携带的目标周期时长以及自身的需求，来确定发起获取请求的时间点。
其中，在当前时间点与接收到所述关键系统信息的时间点之间的累计时长小于所述目标周期时长时，可以在MTC终端有业务触发、寻呼触发的业务需求，或需要进行小区切换时，确定满足所述触发条件，此时MTC终端会发送获取请求到基站，以便获取其他系统信息。如果所述累计时长达到所述目标周期时长，则即使MTC终端没有业务需求或进行小区切换，也需要发送该获取请求到基站，来获取其他系统信息，从而避免MTC终端长时间不与系统进行交互，而导致系统失去对该MTC终端的监控。
上述实施例中，机器类型通信终端可以根据基站下发的目标周期时长以及自身的需要，确定获取其他系统信息的时间点，避免浪费系统资源，提高了5G通信系统的效率。
本公开还提供了另一种信息获取方法，可以用于5G系统中的基站。参照图2根据一示例性实施例示出的一种信息获取方法流程图，可以包括以下步骤：
在步骤201中，在广播关键系统信息后，接收机器类型通信终端在确定满足获取其他系统信息的触发条件时发送的请求获取所述其他系统信息的获取请求；
在步骤202中，根据所述获取请求，定向发送所述其他系统信息到所述机器类型通信终端。
上述实施例中，基站可以在广播关键系统信息后，基于机器类型通信终端在确定满足获取其他系统信息的触发条件时发送的获取请求，定向发送其他系统信息到所述机器类型通信终端。通过上述过程，可以避免采用高频波束扫描方式向机器类型通信终端不停发送其他系统信息而造成的系统资源浪费的问题，更适应于5G中波束扫描的场景。
针对上述步骤201，基站在通过波束扫描的方式发送了关键系统信息后，可以按照相关技术接收MTC终端在确定满足获取其他系统信息的触发条件时发送的请求获取所述其他系统信息的获取请求。其中，所述关键系统信息是终端随机接入基站所需要的最少的系统信息，可以包括MIB，也就是说关键系统信息让各个类型的终端可以驻留并发起随机接入。所述其他系统信息是除了所述关键系统信息之外的其他的系统信息，可以包括SIB。
MTC终端在监测到自身有业务需求或监测到自身需要进行小区切换时，确定满足所述获取请求，此时MTC终端会发送所述获取请求到基站，基站按照相关技术接收即可。
针对上述步骤202，信道互易性是指系统的上下行链路在相同的频率资源的不同时隙上传输，所以在相对较短的时间之内，可以认为上行链路和下行链路的传输信号所经历的信道衰落是相同的，这就是信道互易性。基于信道互易性，可通过基站的上行接收获得下行发送信号将要经历的信道衰落信息，很好地支持基站的波束赋形(智能天线)功能。波束赋形技术通过基站获取的上行信道信息调整下行信号发送过程中的天线阵列各单元的加权系数，产生具有指向性的波束，从而获得明显的阵列增益，在扩大覆盖范围、改善边缘吞吐量以及干扰抑制、干扰协调等方面都具有较大优势。
本公开实施例中，在MTC终端发送所述获取请求到基站的过程中，基站按照信道互易性，可以基于所述获取请求定向将所述其他系统信息发送给该MTC终端。
在一实施例中，参照图3所示，图3是根据一示例性实施例示出的另一种信息获取方法流程图，上述信息获取方法还可以包括：
在步骤200中，为所述机器类型通信终端配置广播所述其他系统信息的目标周期时长，所述目标周期时长超过所述基站广播系统信息块SIB中SIB1的周期时长。
本步骤中，基站可以针对MTC终端的低移动性、时间可容忍性等特点，为MTC终端配置广播所述其他系统信息的目标周期时长。为了节省系统资源，该目标周期时长可以较长。可选地，可以超过所述基站广播系统信息块SIB中SIB1的周期时长。例如，所述目标周期时长可以为320毫秒甚至1024毫秒等。
进一步地，基站在广播的关键系统信息中携带该目标周期时长。
MTC终端接收后，可以基于该目标周期时长和自身需求，确定发送获取请求的时间点。即MTC终端可以在当前时间点与接收到所述关键系统信息的时间点之间的累计时长达到目标周期时长时，无论是否有业务需求或需要进行小区切换，均发送获取请求到基站，来获取其他系统信息。或者在所述累计时长小于所述目标周期时长时，如果监测到有业务需求或需要进行小区切换时，发送获取请求到所述基站。
上述实施例中，基站可以为机器类型终端配置广播所述其他系统信息的目标周期时长，且该目标周期时长可以较长，超过所述基站广播系统信息块SIB中SIB1的周期时长。基站通过关键系统信息将所述目标周期时长广播出去，当机器类型通信终端接收后，可根据基站下发的目标周期时长以及自身的需要，确定获取其他系统信息的时间点，避免浪费系统资源，提高了5G通信系统的效率。
在本公开实施例中，如果是其他类型终端，例如移动终端与基站进行交互时，由于移动终端对时延要求较高，无法在满足触发条件时才去获取其他系统信息。因此，移动终端可以在接收到基站广播的关键系统信息后，就主动发送请求获取其他系统信息的获取请求，从而获得其他系统信 息。无需在所述累计时长达到所述目标周期时长、或所述累计时长小于所述目标时长，但有业务需求或需进行小区切换时，才去获取其他系统信息。
本公开还提供了另一种信息获取方法，参照图4根据一示例性实施例示出的一种信息获取方法流程图，可以包括以下步骤：
在步骤301中，基站为机器类型通信终端配置广播其他系统信息的目标周期时长。
可选地，目标周期时长可以较长，例如超过所述基站广播系统信息块SIB中SIB1的周期时长。
在步骤302中，基站广播携带所述目标周期时长的关键系统信息。
在步骤303中，MTC终端接收到所述关键系统信息后，检测是否满足获取其他系统信息的触发条件。
可选地，所述MTC终端在当前时间点与接收到所述关键系统信息的时间点之间的累计时长小于所述目标周期时长时，监测是否有业务需求或是否需要进行小区切换。
所述MTC终端在所述累计时长达到所述目标周期时长、或所述累计时长小于所述目标周期时长时，监测到有业务需求、或所述累计时长小于所述目标周期时长时，监测到需要进行小区切换时，均认为满足所述触发条件。此时，继续执行步骤304。
在步骤304中，MTC终端发送请求获取所述其他系统信息的获取请求到所述基站。
在步骤305中，基站根据所述获取请求，定向发送所述其他系统信息到所述MTC终端。
当然，其他类型终端，例如移动终端对时延要求较高，因此，在接收到基站广播的关键系统信息后，立即发送请求获取其他系统信息的获取请求到所述基站，以便获取其他系统信息。
上述实施例中，针对MTC终端的低移动性、时间可容忍性等特点，基站为MTC终端配置了广播其他系统信息的一个较长的目标周期时长。 MTC终端在接收到基站广播的关键系统信息后，所述累计时长小于目标周期时长时，可以基于业务需求或小区切换需求，随时发起请求获取其他系统信息的获取请求到基站，从而获取所述其他系统信息，或者MTC终端在所述累计时长达到所述目标周期时长时，直接发起所述获取请求到所述基站，同样获取所述其他系统信息。通过上述过程，MTC终端在接收到关键系统信息后，可以根据自身的需要或目标周期时长，来确定获取其他系统信息的时间点，无需保持对其他系统信息的高频率的监听，避免浪费系统资源，提高了5G通信系统的效率。
