物联网(Internet of things,IOT)实现了物与物之间的通信。与传统的人与人之间通信相比,物联网对终端设备的能耗提出了更高的要求,需要尽量降低终端设备能耗,从而保证设备超长的待机时间,降低更换电池的人力成本。
考虑到物联网通信具有业务低速率、周期长的特点,对于处于空闲态的终端设备配置较长的非连续接收(discontinuous reception,DRX)周期,以达节电、延长终端设备待机时间的目的。
物联网可基于蜂窝网络实现,比如:基于长期演进(Long Term Evolution,LTE)系统实现物联网通信。LTE系统中通常通过寻呼消息通知终端设备系统消息(System Information)变更,即在一个系统消息变更周期内,发送寻呼消息通知终端设备:在下一个系统消息变更周期系统消息会变更,终端设备在该下一个系统消息变更周期读取变更后的系统消息。
通常,如图1所示,LTE系统中系统消息变更周期为寻呼消息发送的周期,即寻呼周期的整数倍,这样当系统消息变更时,处于无线资源控制空闲(Radio Resource Control IDLE,RRC_IDLE)状态(以下简称“空闲态”)的终端设备在系统消息变更周期内只要读取到一个寻呼消息,即可获知系统消息即将变更,通过在下一个系统消息变更周期读取系统消息,完成系统消息的更新,其中,终端设备在系统消息变更周期中成功完成系统消息更新后,就不必再读取该周期中后续发送的系统消息。
通常,LTE系统中,寻呼周期与DRX周期相等。当基于LTE系统实现物 联网通信时,由于长DRX周期的使用,可能导致寻呼周期大于系统消息变更周期,如图2所示,此时处于空闲态的终端设备可能无法收到用于指示系统消息变更的寻呼消息,因此无法实现系统消息的更新。
因此,在诸如物联网通信等无线通信过程中,当终端设备的DRX周期大于系统消息变更周期时,可能导致终端设备无法正常更新系统消息。
发明内容
有鉴于此,本申请提供一种系统消息传输装置、方法和系统,用于解决终端设备的DRX周期大于系统消息变更周期,导致终端设备可能无法正常更新系统消息的问题。
第一方面,本申请提供一种终端设备,包括:
接收模块,用于接收所述终端设备所在小区的第一系统消息;
处理模块,用于获取所述接收模块接收的所述第一系统消息中的第一指示信息,所述第一指示信息包括用于更新除了所述第一系统消息之外的其他系统消息的信息;并根据获取的所述第一指示信息,针对除了第一系统消息之外的其他系统消息进行更新;
其中,所述第一系统消息周期性发送,且占用的物理资源位置固定。
第二方面,本申请提供一种网络设备,包括:
处理模块,用于确定第一系统消息,所述第一系统消息中包括第一指示信息,所述第一指示信息包括用于更新除了所述第一系统消息之外的其他系统消息的信息;
发送模块,用于将所述处理模块确定的所述第一系统消息在小区内发送;
其中,所述第一系统消息周期性发送,且占用的物理资源位置固定。
第三方面,本申请提供一种更新系统消息的方法,包括:
第一终端设备接收所在小区的第一系统消息;
所述第一终端设备从所述第一系统消息中获取第一指示信息,所述第一指示信息包括用于更新除了所述第一系统消息之外的其他系统消息的信息;
所述第一终端设备根据获取的所述第一指示信息,针对除了第一系统消息之外的其他系统消息进行更新;
其中,所述第一系统消息周期性发送,且占用的物理资源位置固定。
第四方面,本申请提供一种更新系统消息的方法,包括:
网络设备确定第一系统消息,所述第一系统消息中包括第一指示信息,所述第一指示信息包括用于更新除了所述第一系统消息之外的其他系统消息的信息;
所述网络设备将确定的所述第一系统消息在小区内发送;
其中,所述第一系统消息周期性发送,且占用的物理资源位置固定。
第五方面,本申请提供一种无线通信系统,包括:
网络设备,用于在小区内发送所述第一系统消息,所述第一系统消息中包括第一指示信息,所述第一指示信息包括用于更新除了所述第一系统消息之外的其他系统消息的信息;
终端设备,用于接收所述网络设备发送的所述第一系统消息,从所述第一系统消息中获取第一指示信息,根据获取的所述第一指示信息,针对除了第一系统消息之外的其他系统消息进行更新;
其中,所述第一系统消息周期性发送,且占用的物理资源位置固定。
上述任一方面中,第一指示信息是在第一系统消息中发送的,而不是在寻呼消息中发送,由于第一系统消息是周期性发送,且占用的物理资源位置固定,因此终端设备可根据该指示信息对除了第一系统消息之外的其他系统消息进行更新,从而实现对所有系统消息的更新。与目前通过寻呼消息获知系统消息变更的方案相比,避免了终端设备的DRX周期大于系统消息变更周期,终端设备可能无法收到用于指示系统消息变更的寻呼消息,进而无法实现系统消息的更新的问题。
结合上述任一方面,在第一种可能的实现方式中,除了所述第一系统消息之外的其他系统消息包括:第二系统消息,至少两个第三系统消息,所述至少两个第三系统消息包括至少一个常规类第三系统消息和至少一个激活类 第三系统消息;
所述第二系统消息,包括所述至少两个第三系统消息的调度信息;
所述激活类第三系统消息,包括所述小区的特定功能激活时所述小区内的终端设备需要获取的系统消息;所述常规类第三系统消息为所述至少两个第三系统消息中除了激活类第三系统消息之外的其他所述第三系统消息。
其中,将第三系统消息进行进一步细分,分为激活类第三系统消息和常规类第三系统消息,因此,当更新这些系统消息时,可采用更为灵活的指示方式,终端设备进行系统消息更新的方法更灵活。
结合上述任一方面的第一种可能的实现方式,在第二种可能的实现方式中,
所述第一指示信息包括:第二指示信息,所述第二指示信息用于指示所述小区当前使用的所述第二系统消息和所述至少一个常规类第三系统消息的组合的配置版本,在一个系统消息更新周期内,所述第二系统消息和所述至少一个常规类第三系统消息中的任何一个或多个系统消息更新,所述配置版本变化一次时,
若所述第二指示信息指示的所述配置版本与终端设备已记录的所述配置版本不同,则终端设备更新所述第二系统消息;
若所述第二指示信息指示的所述配置版本与终端设备已记录的所述配置版本相同,则终端设备确定无需更新所述第二系统消息。
其中,终端设备可根据第二指示信息即可判断是否需要读取系统消息,能够降低能耗,节省处理能力。
结合上述任一方面的第二种可能的实现方式,在第三种可能的实现方式中,所述第二系统消息中包括至少一个第三指示信息,一个所述第三指示信息对应于一个所述常规类第三系统消息,用于指示相对于最近一次所述配置版本变化,对应的所述常规类第三系统消息是否已更新时,在更新所述第二系统消息之后,从所述第二系统消息中获取所述至少一个第三指示信息;
若所述第二指示信息指示的所述配置版本与所述终端设备已记录的所述 配置版本不同,但两个所述配置版本中间不存在其他不同的所述配置版本,则执行如下操作:
若所述至少一个第三指示信息中每一个所述第三指示信息均指示相对于最近一次所述配置版本变化,对应的所述常规类第三系统消息并未更新,则确定无需更新所述至少一个常规类第三系统消息中的任何一个系统消息;
若所述至少一个第三指示信息中存在一个或多个所述第三指示信息,指示相对于最近一次所述配置版本变化,对应的所述常规类第三系统消息已更新,则针对每一个已更新的所述常规类第三系统消息,按照更新后的所述第二系统消息中该常规类第三系统消息的调度信息,控制所述接收模块读取该常规类第三系统消息。
其中,针对每一个常规类第三系统消息进行,指示该消息是否更新,一方面,终端设备可仅针对更新了的常规类第三系统消息进行系统消息更新,降低能耗,节省处理能力;另一方面,终端设备也可根据各个第三指示信息在确定所有常规类第三系统消息未更新时,确定无需更新常规类第三系统消息,也能够降低能耗,节省处理能力。
结合上述任一方面的第三种可能的实现方式,在第四种可能的实现方式中,若所述第二指示信息指示的所述配置版本与终端设备已记录的所述配置版本中间存在其他不同的所述配置版本,则
针对每一个所述常规类第三系统消息,按照更新后的所述第二系统消息中该常规类第三系统消息的调度信息,控制所述接收模块读取该常规类第三系统消息。
其中,若所述第二指示信息指示的所述配置版本与终端设备已记录的所述配置版本中间存在其他不同的所述配置版本,则仅根据第三指示信息无法正确判断对应的常规类第三系统消息是否已更新,此时,终端设备需要更新所有的常规类第三系统消息。
结合上述任一方面的第一种至第四种可能的实现方式中的任一种,在第五种可能的实现方式中,所述第一指示信息还包括:至少一个第四指示信息, 一个所述第四指示信息对应于一个所述激活类第三系统消息,用于指示所述小区内的终端设备是否需要更新对应的所述激活类第三系统消息时,
若所述第四指示信息指示所述小区内的终端设备需要更新对应的所述激活类第三系统消息,则终端设备更新对应的所述激活类第三系统消息;
若所述第四指示信息指示所述小区内的终端设备无需更新对应的所述激活类第三系统消息,则终端设备确定无需更新对应的所述激活类第三系统消息。
其中,针对每一个激活类第三系统消息,指示该系统消息是否需要更新,并且由于激活类第三系统消息是所述小区的特定功能激活时所述小区内的终端设备需要获取的系统消息,因此,在指示激活类第三系统消息是否需要更新时,是通知终端设备所述小区的特定功能已激活,不同于常规类第三系统消息,终端设备无需再结合其他指示信息判断是否需要进行系统消息更新,当第四指示信息指示对应的激活类第三系统消息需要更新时,则终端设备确定需要更新该激活类第三系统消息,当第四指示信息指示对应的激活类第三系统消息无需更新时,则终端设备确定无需更新该激活类第三系统消息,与前述的常规类第三系统消息的更新机制不同。
第六方面,本申请提供一种终端设备,包括:
接收模块,用于接收所述终端设备所在小区的第一系统消息;所述小区的系统消息包括:所述第一系统消息、第二系统消息和至少一个第三系统消息;所述第一系统消息周期性发送,且占用的物理资源位置固定;所述第二系统消息包括所述至少一个第三系统消息的调度信息;所述至少一个第三系统消息中包括与寻呼有关的系统消息;
处理模块,用于获取所述接收模块接收的所述第一系统消息中的第一指示信息,所述第一指示信息用于指示所述与寻呼有关的系统消息是否已更新;以及若所述第一指示信息指示所述与寻呼有关的系统消息未更新,则控制所述接收模块按照已记录的所述与寻呼有关的系统消息接收寻呼消息,并根据所述接收模块接收的所述寻呼消息中与系统消息更新有关的第二指示信息进 行系统消息更新。

所述小区的系统消息包括:所述第一系统消息、第二系统消息和至少一个第三系统消息;所述第一系统消息周期性发送,且占用的物理资源位置固定;所述第二系统消息包括所述至少一个第三系统消息的调度信息;所述至少一个第三系统消息中包括与寻呼有关的系统消息。
上述第六方面至第十方面的任一方面中,由于网络设备在周期性发送的第一系统消息中指示与寻呼有关的系统消息是否已更新,如果没有更新,则终端设备仍可以按照已记录的与寻呼有关的系统消息来正常接收寻呼消息, 进而从寻呼消息中获得与系统消息更新有关的指示信息,并按照从寻呼消息中获得的该指示信息更新系统消息。这样,即使DRX周期大于系统消息更新周期,由于已知与寻呼消息有关的系统消息未更新,则终端设备仍能按照已记录的与寻呼有关的系统消息正确接收寻呼消息,从而能够成功地从寻呼消息中获得与系统消息更新有关的指示信息,进而能够成功更新系统消息。

具体实施方式
为了更好地理解本申请的上述目的、方案和优势,下文提供了详细描述。 该详细描述通过使用框图、流程图等附图和/或示例,阐明了装置和/或方法的各种实施方式。在这些框图、流程图和/或示例中,包含一个或多个功能和/或操作。本领域技术人员将理解到:这些框图、流程图或示例内的各个功能和/或操作,能够通过各种各样的硬件、软件、固件单独或共同实施,或者通过硬件、软件和固件的任意组合实施。
一方面,本申请提供一种更新系统消息的方案,该方案中,网络设备在发送的第一系统消息中携带指示信息,终端设备在收到该第一系统消息后,根据该指示信息对除了第一系统消息之外的其他系统消息进行更新;其中,第一系统消息周期性发送,且占用的物理资源位置固定。
该方案中,指示信息是在第一系统消息中发送的,而不是在寻呼消息中发送,终端设备可根据该指示信息对除了第一系统消息之外的其他系统消息进行更新,从而实现对所有系统消息的更新。与目前通过寻呼消息获知系统消息变更的方案相比,避免了终端设备的DRX周期大于系统消息变更周期,终端设备可能无法收到用于指示系统消息变更的寻呼消息,因此无法实现系统消息的更新的问题。
另一方面,本申请提供另一种更新系统消息的方案,该方案中,网络设备在发送的系统消息包括:第一系统消息、第二系统消息和至少一个第三系统消息,其中,第一系统消息周期性发送,且占用的物理资源位置固定;第二系统消息包括至少一个第三系统消息的调度信息;至少一个第三系统消息中包括与寻呼有关的系统消息;其中,网络设备在发送第一系统消息时,携带指示信息,该指示信息用于指示第三系统消息中与寻呼有关的系统消息是否已更新。若指示信息指示与寻呼有关的系统消息未更新,则终端设备按照已记录的所述与寻呼有关的系统消息,接收寻呼消息,并根据接收的寻呼消息中与系统消息更新有关的指示信息进行系统消息更新。
该方案中,由于网络设备在周期性发送的第一系统消息中指示与寻呼有关的系统消息是否已更新,如果没有更新,则终端设备仍可以按照已记录的与寻呼有关的系统消息来正常接收寻呼消息,进而从寻呼消息中获得与系统 消息更新有关的指示信息,并按照从寻呼消息中获得的该指示信息更新系统消息。这样,即使DRX周期大于系统消息更新周期,由于已知与寻呼消息有关的系统消息未更新,则终端设备仍能按照已记录的与寻呼有关的系统消息正确接收寻呼消息,从而能够成功地从寻呼消息中获得与系统消息更新有关的指示信息,进而能够成功更新系统消息。
再一方面,本申请提供再一种更新系统消息的方案,该方案针对能够正常接收寻呼消息的场景,比如:系统消息更新周期为DRX周期的整数倍。该方案中,网络设备在发送寻呼消息时,寻呼消息中携带的系统消息更新指示信息分别针对第一系统消息、第二系统消息、至少一个第三系统消息,指示第一终端设备是否需要更新该系统消息;终端设备根据系统消息更新指示信息进行系统消息更新;其中,第一系统消息周期性发送,且占用的物理资源位置固定;第二系统消息,包括至少一个第三系统消息和的调度信息。
该方案中,通过在寻呼消息携带针对每一个系统消息的指示信息,该指示信息用于指示对应的系统消息是否需要更新,终端设备可根据各个指示信息的具体情况,确定如何进行系统消息更新。比如:第二系统消息的指示信息指示第二系统消息无需更新,则终端设备在进行至少一个第三系统消息更新时,仅需根据已记录的第二系统消息进行更新,无需再重新读取第二系统消息,提高了终端设备更新系统消息的效率。
又一方面,本申请提供一种系统消息的发送方案,网络设备在发送一个系统消息时,在整个系统消息的两次发送之间的时间间隔内,发送其他一个或多个系统消息。
目前,每一个系统消息只能在一个SI窗口(SI-window)中发送,在该系统消息窗中可以发送多次,一个系统消息的SI窗口和另一个系统消息的SI窗口相邻,但一个SI窗中仅能发送一个系统消息,终端设备在一个SI窗口中收到系统消息后,必须要等到下一个SI窗口收下一个系统消息。而本申请提供的该方案中,由于在一个系统消息的两次重复发送过程中,网络设备还发送其他系统消息,这样终端设备在收完一个系统消息后,无需等待系统消息 窗的到来,可以收其他系统消息,提高了系统消息更新的效率。
下面,为了便于理解,介绍本申请涉及的基本概念。
1、CIoT
蜂窝物联网(Cellular Internet of Things,CIoT),是指基于蜂窝网络实现的物联网。
为了应对未来爆炸性的移动数据流量增长、海量的设备连接、不断涌现的各类新业务和应用场景,产生了第五代移动通信(5th Generation,5G)系统。物联网可作为5G系统的组成部分,其市场需求增长迅猛,预测显示,到2022年基于5G系统实现的物联网中,连接数将会达到180亿。
目前,第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)正在研究基于蜂窝网络的物联网,设计新的空口(也称为“空中接口”或“无线接口”)技术来承载物联网的业务。
本申请中提出的系统消息传输方案可用于IoT中,也可用于CIoT中,用以解决物联网中,当终端设备的DRX周期大于系统消息变更周期时,可能导致终端设备无法正常更新系统消息的问题,但并不意味着只能应用于IoT中。实际上,只要终端设备的DRX周期大于系统消息变更周期,均可能导致终端设备无法正常更新系统消息,本申请提出的方案用于解决由于终端设备的DRX周期大于系统消息变更周期导致的终端设备无法正常更新系统消息的问题,对所应用的系统或网络并不做限定。
2、系统信息
系统信息是无线通信系统中,网络设备,比如基站,向一个小区内的终端设备发送的消息,消息中包括该小区的小区级别的信息,对于接入该小区的所有终端设备有效。通常,网络设备采用广播方式发送系统信息。
按照系统信息的内容和重要程度等,可将系统信息进一步细分。下面,以目前LTE系统中的系统消息为例,对系统信息的组成加以说明,其他系统虽然划分方式略有不同,但原理基本相同,这里不再赘述。
LTE系统中,系统信息可分为主信息块(MasterInformationBlock,MIB) 和多个系统信息块(SystemInformationBlock,SIB),其中SIB由分为SIB1和其他SIB。每个系统信息包含了与某个功能相关的一系列参数集合。
LTE系统中,有3种类型的RRC消息用于传输系统信息,分别为:
1)MIB消息,用于传输MIB;
2)SIB1消息,用于传输SIB1;
3)一个或多个SI消息,用于传输除了SIB1之外的其他SIB。
其中,MIB消息在物理广播信道(Physical Broadcast CHannel,PBCH)上传输,时频资源固定。若存在SIB1,则由物理下行控制信道(Physical Downlink Control CHannel,PDCCH)信令来调度用于传输SIB1消息的频域资源,用于传输SIB1消息的时域资源固定。
与MIB消息所在的时频位置固定不同,SIB1消息和SI消息均在物理下行共享信道(Physical Downlink Shared CHannel,PDSCH)上传输,且SIB1消息和SI消息所占的资源块(Resource Block,RB)(频域上的位置)及其传输格式等均是动态调度的,由PDCCH信令来指示。UE通过在一个子帧的PDCCH上盲检来确定该子帧是否存在SI消息(SIB1在时域上的位置固定)。
演进节点B(evloved NodeB,eNB)可以根据具体情况灵活地改变SIB1消息和SI消息所占的带宽、使用的RB集合以及传输格式等。每个SI消息包含了一个或多个除SIB1外的SIB,这些SIB具有相同的调度需求,(比如:相同的传输周期)。
SIB1消息中指定了SI消息中包含了哪些SIB,以及该SI消息的周期、调度信息等。
本申请中,将系统消息进行如下划分:
1)、第一系统消息:在物理广播信道(比如:LTE系统中的PBCH)上周期发送,占用的物理资源位置固定(比如:对于LTE系统,占用的时域资源位置和频域资源位置固定)。通常第一系统消息的发送周期小于系统消息更新周期。
对于LTE系统,该第一系统消息可为MIB消息,发送周期为40ms。
2)、第二系统消息:在业务信道(比如:LTE系统中的PDSCH)上发送,占用的物理资源位置不固定(或者仅时域位置固定,频域位置通过调度信令指示),该第二系统消息中包括至少一个第三系统消息的调度信息。第二系统消息可周期发送,若周期发送,通常第二系统消息的发送周期小于系统消息更新周期,且大于第一系统信息的发送周期。
对于LTE系统,该第二系统消息可为SIB1消息,用于传输SIB1,SIB1消息周期发送,发送周期为80ms。
3)、至少一个第三系统消息:在业务信道(比如:LTE系统中的PDSCH)上发送,占用的物理资源位置不固定。
比如:对于LTE系统,第三系统消息为SI消息。
在实施例一中,系统消息中包括至少两个第三系统消息,该至少两个系统消息包括至少一个常规类第三系统消息和至少一个激活类第三系统消息。
其中,激活类第三系统消息为小区特定功能激活时小区内的终端设备需要获取的系统消息,常规类第三系统消息为上述至少两个系统消息中,除了激活类第三系统消息之外的其他系统消息。
以LTE系统为例,所有SI消息中,用于传输SIB 10、SIB11、SIB12、SIB14的SI消息可为激活类第三系统消息,SI消息中的其他系统消息为常规类第三系统消息。
可选地,一个常规类第三系统消息可传输至少一个系统信息,当其中的一个或多个系统信息发生变更时,则认为传输该系统信息的常规类第三系统消息需要更新;一个激活类第三系统消息也可传输至少一个系统信息,当其中的一个或多个系统信息发生变更时,则认为传输该系统信息的激活类第三系统消息需要更新。此时,可将第三系统消息和系统信息之间的关系称为一对多的关系。
或者,可选地,一个常规类第三系统消息可传输至少一个系统信息,当其中的一个或多个系统信息发生变更时,则认为传输该系统信息的常规类第三系统消息需要更新;一个激活类第三系统消息只传输一个系统信息,当该 一个系统信息发生变更时,则认为传输该系统信息的激活类第三系统消息需要更新。此时,可将常规类第三系统消息和系统信息之间的对应关系称为一对多的关系,可将激活类第三系统消息和系统信息之间的对应关系称为一对一的关系。
再或者,可选地,一个常规类第三系统消息仅传输一个系统信息,当该一个系统信息发生变更时,则认为传输该系统信息的常规类第三系统消息需要更新;一个激活类第三系统消息可传输至少一个系统信息,当其中的一个或多个系统信息发生变更时,则认为传输该系统信息的激活类第三系统消息需要更新。此时,可将常规类第三系统消息和系统信息之间的对应关系称为一对一的关系,可将激活类第三系统消息和系统信息之间的对应关系称为一对多的关系。
再或者,可选地,一个常规类第三系统消息仅传输一个系统信息,当该一个系统信息发生变更时,则认为传输该系统信息的常规类第三系统消息需要更新;一个激活类第三系统消息仅传输一个系统信息,当该一个系统信息发生变更时,则认为传输该系统信息的激活类第三系统消息需要更新。此时,可将第三系统消息和系统信息之间的对应关系称为一对一的关系。
目前LTE系统中,当终端设备通过读取寻呼消息获知需要进行系统信息更新时,需要读取所有的系统消息。而本申请中,针对不同的系统消息,指示该系统消息是否需要更新,则终端设备无需读取不需要更新的系统消息,降低了能耗,节省了处理能力。特别当系统消息与系统信息是一对一的关系时,可以细化到每一个系统信息,只要当一个系统信息发生变更时,终端设备才需要读取对应的系统消息,与系统消息与系统信息一对多的关系相比,划分更细致,能够进一步降低终端设备的能耗和处理能力,但这要求网络设备在指示系统信息变更时,需要更多的信息比特,相对提高了控制信息的开销。
对于第一系统消息和第二系统消息,由于系统消息中仅包括一个系统信息,所以可认为是系统消息与系统信息之间是一对一的对应关系。
所以,本申请中,为了便于理解,在系统消息与系统信息是一对一的对应关系时,认为系统信息变更,则对应的系统消息需要更新;在系统消息与系统信息是一对多的对应关系时,认为任何一个或多个系统信息变更,则对应的系统消息需要更新。后面的描述中,不再明确区分系统信息的更新和系统消息的更新。
3、目前LTE系统中通知系统消息变更的方案
目前,LTE系统中,通过寻呼和ValueTag两种方式通知终端设备即将到来的系统消息变更,其中,以寻呼方式为主。当小区即将修改某些系统信息时,基站会先对当前系统消息变更周期内的所有寻呼消息中的systemInfoModification字段置1,指示系统消息即将发生变化(但并不发送更新后的内容),然后在紧接着的下一个系统消息变更周期,小区才会发送更新后的系统信息。终端通过接收寻呼消息并检测字段systemInfoModification,可以预知系统消息即将改变,进而在下一系统消息变更周期开始时重新接收所有系统消息。
对于处于空闲态的终端来说,为节约终端能耗,在绝大多数时间处于休眠状态。但是会每隔一段时间(DRX周期)醒来一次,接收系统周期发送的寻呼消息,然后再进入休眠状态。其中,DRX周期就等于寻呼周期。在LTE系统中,系统消息变更周期为寻呼周期的整数倍,也就是说,当系统信息改变之前,终端有多次机会接收寻呼消息,并读取其中的systemInfoModification字段,以获取系统信息是否改变的信息。若systemInfoModification=1,该终端将在下一系统消息变更周期开始处,按以下顺序读取系统信息:
1)、读取MIB。
2)、监听物理下行控制信道(Physical Downlink Control CHannel,PDCCH),根据由系统消息-无线网络临时标识(System Information-Radio Network Temporary Identity,SI-RNTI)加扰的PDCCH信息,获取SIB1的频域调度信息,并根据固定的时域调度信息,确定SIB1的时频位置,读取SIB1;
3)、通过SIB1中包括的各SI的周期、调度信息以及SI与其他各SIB的 映射关系等信息,确定各系统消息的资源位置;
4)、读取所有SI消息。
对于处于空闲态的终端来说,系统消息变更周期是寻呼周期的整数倍,也就是说,在一次系统消息变更周期内,终端会有数次机会接收寻呼消息,因此,目前LTE系统中通过寻呼消息指示系统消息变更是可靠的。
但是,如前所述,若使用长DRX周期,比如在CIoT中,由于长DRX周期的使用,寻呼周期可能会大于系统消息变更周期,当终端醒来准备接收寻呼消息时,系统信息(特别是关于寻呼的系统信息)可能已经发生变更,此时对于终端来说,并不能保证能够成功接收系统消息。
因此,在诸如CIoT的长DRX系统中,目前的以寻呼方式为主的通知系统消息变更的方式并不可靠。
除此之外,SIB并不是在每次变更周期都会同时变化,可能仅有部分变化发生,单独的systemInfoModification指示,只能指示是否变化,不能指示哪些变化,因此目前LTE系统中要求终端重收所有系统消息,比较费电。
4、SI窗口(SI-window)和SI消息的调度
目前LTE系统中,每个SI消息只在一个SI窗口中传输。其中:
1)一个SI消息跟一个SI窗口相关联,该SI窗口内只能发这个SI消息且可以重复发送多次(发多少次,在哪些子帧上发送等,取决于基站的实现),但不能发送其它SI消息;
2)SI窗口之间是紧挨着的(如果相邻的话),既不重叠,也不会有空隙;
3)所有SI消息的SI窗口长度都相同;
4)不同SI消息的周期是相互独立的。
目前LTE系统中,MIB和SIB1的时域调度是固定的,SI消息的时域调度过程如下:
1)终端确认每个SI消息对应的SI窗口的起始位置以及SI窗口的长度。
SI窗口的长度由SIB1的si-WindowLength字段指定,其以ms为单位。
SIB1的schedulingInfoList指定了SI消息的列表,每个SI消息在该列表 中的顺序以n表示(从1开始)。
此时每个SI消息有一个x=(n-1)*w,其中w为si-WindowLength。可以看出,x是以ms为单位的。
则SI窗口的起始帧满足SFN%T=FLOOR(x/10),其中T为对应的SI消息的周期,由si-Periodicity指定(以系统帧为单位,即以10ms为单位)。通过SFN%T的运算,保证了不同SI的窗是紧挨着的,FLOOR(x/10)确定SI窗口在周期内的起始系统帧(一个系统帧为10ms,所以有x/10)。其中,%表示取余运算,FLOOR表示返回小于或者等于表达式的最大整数,/表示除法。
SI窗口的起始子帧为#a,其中a=x%10。
从上述公式可以看出,x决定了SI窗口在该SI周期内的起始帧和起始子帧;SFN%T保证了SI窗口在SI周期内只出现一次;而x=(n-1)*w保证了SI窗口之间紧挨(如果相邻的话),不重叠,没有空隙。
SI窗口确定了以后,基站会决定在该SI窗口内调度多少次同一SI,不同厂商的实现可能不同,但某些子帧不能用于调度SI消息,这些子帧包括:
1)SFN%2=0的系统帧内的子帧5,该子帧用于SIB1的传输;
2)任一多播/组播单频网络(Multimedia Broadcast multicast service Single Frequency Network,MBSFN)子帧;
3)时分双工(Time Division Duplexing,TDD)LTE系统中的上行子帧。

图3示出了本申请提供的无线通信系统,该无线通信系统的架构适用于本申请各实施例。
如图3所示,该无线通信系统包括:网络设备301以及至少一个终端设备302。
该网络设备301在一个小区内发送系统消息,至少一个终端设备302接收网络设备301发送的系统消息。

其中,终端设备302可以是无线终端,无线终端可以是指向用户提供语音和/或数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线 调制解调器的其他处理设备。无线终端可以经无线接入网(例如,RAN,Radio Access Network)与一个或多个核心网进行通信,无线终端可以是移动终端,如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。例如,个人通信业务(PCS,Personal Communication Service)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(WLL,Wireless Local Loop)站、个人数字助理(PDA,Personal Digital Assistant)等设备。无线终端也可以称为订户单元(Subscriber Unit)、订户站(Subscriber Station),移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、接入点(Access Point)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device)、或用户装备(User Equipment)。

【实施例二】
如图5所示,实施例二提供的系统消息更新流程包括如下步骤:
S501:网络设备301在小区内发送第一系统消息,第一系统消息中携带第一指示信息,该第一指示信息与系统消息更新有关;
S502:终端设备302在收到该第一系统消息后,获取第一系统消息中的第一指示信息,并根据该第一指示信息对除了第一系统消息之外的其他系统消息进行更新。
其中,第一系统消息是周期性发送的,且占用的物理资源位置固定,终端设备302可处于空闲态,且预先知道第一系统消息的发送周期、发送时刻和物理资源位置,终端设备302可在每个DRX周期内,在醒来时读取第一系统消息。可选地,终端设备302可在醒来后,读取寻呼消息前读取第一系统消息。
第一系统消息的发送周期可依据产品实现而定,比如:40ms。
可选地,若所述第一指示信息指示需要更新除了第一系统消息之外的其他系统消息,则终端设备302确定需要进行系统消息更新,并进行系统消息;若所述第一指示信息指示无需更新除了第一系统消息之外的其他系统消息,则终端设备302确定无需进行系统消息更新,这样通过读取第一系统消息中的第一指示信息,无需读取其他系统消息即可确定是否要读取除了第一系统消息之外的其他系统消息,达到了省电和节省处理能力的目的。
下面,举例介绍第一指示信息的几种可选实现方案。
可选方案一
该第一指示信息可通过一个ValueTag指示所有的系统消息是否需要更 新,比如:该ValueTag取值范围为0~31,系统消息每更新一次,ValueTag值加1。这里,系统消息每更新一次,是指在一个系统消息更新周期内,只要除了第一系统消息之外的其他系统消息中有发生改变的,则系统消息更新一次,且不管有几个系统消息发生改变,ValueTag值仅加1。这样,终端设备302在第一指示信息的ValueTag值发生改变时,确定需要更新系统消息,若ValueTag值未变,则确定无需更新系统消息。
可选方案二
该第一指示信息包括:(1+M)个ValueTag,该(1+M)个ValueTag中,一个用于指示第二系统消息是否需要更新,M个ValueTag分别对应于M个常规类第三系统消息,每一个用于指示对应的常规类第三系统消息是否需要更新,这(1+M)个ValueTag的设置可同可选方案一中ValueTag的设置,M为正整数。
此外,第一指示信息还可包括N个激活指示信息,该N个激活指示信息分别用于指示N个激活类第三系统消息中每一个系统消息是否需要更新,当取值为“1”时,表明需要更新,当取值为“0”时,表明无需更新,N为正整数。
可选方案三
可选地,第一指示信息包括:第二指示信息;
第二指示信息用于指示小区当前使用的第二系统消息和至少一个常规类第三系统消息的组合的配置版本,在一个系统消息更新周期内,第二系统消息和至少一个常规类第三系统消息中的任何一个或多个系统消息更新,版本变化一次;
步骤S502中,终端设备302在获取第一指示信息后,若其中的第二指示信息指示的配置版本与终端设备302已记录的配置版本不同,则终端设备302更新第二系统消息;若第二指示信息指示的配置版本与终端设备302已记录的配置版本相同,则终端设备302确定无需更新第二系统消息。可选地,该第二指示信息也可以采用ValueTag的方式实现。
可选地,第二系统消息中包括M个第三指示信息分别对应于M个常规类第三系统消息。第三指示信息用于指示相对于最近一次配置版本变化,对应的常规类第三系统消息是否已更新;在终端设备302更新第二系统消息之后,从第二系统消息中获取至少一个第三指示信息。
这里区分第二指示信息指示的配置版本,可有如下多种情况:
情况一、
第二指示信息指示的配置版本与终端设备302已记录的配置版本不同,但两个配置版本中间不存在其他不同的配置版本。
在情况一下,若至少一个第三指示信息中每一个第三指示信息均指示相对于最近一次配置版本变化,对应的常规类第三系统消息并未更新,则终端设备302确定无需更新至少一个常规类第三系统消息中的任何一个系统消息;
在情况一下,若至少一个第三指示信息中存在一个或多个第三指示信息,指示相对于最近一次配置版本变化,对应的常规类第三系统消息已更新,则针对每一个已更新的常规类第三系统消息,终端设备302按照更新后的第二系统消息中该常规类第三系统消息的调度信息,读取该常规类第三系统消息。
情况二、
第二指示信息指示的配置版本与终端设备302已记录的配置版本中间存在其他不同的配置版本。
在情况二下,终端设备302针对每一个常规类第三系统消息,按照更新后的第二系统消息中该常规类第三系统消息的调度信息,读取该常规类第三系统消息。
在情况二下,终端设备302要更新每一个常规类第三系统消息,这是因为:第二指示信息指示的配置版本与终端设备302已记录的配置版本中间存在其他不同的配置版本,并且第二指示信息用于指示小区当前使用的第二系统消息和至少一个常规类第三系统消息的组合的配置版本,这表明终端设备302可能错过了至少一次的系统消息更新过程。比如:如果一个常规类第三系统消息较上一个配置版本并没有变化,但是较再之前的配置版本有变化,则 对应的第三指示信息取值仍为“0”,这时根据第三系统消息确定是否需要更新该常规类第三系统消息是不准确的。因此,终端设备302为保证所保存的系统消息有效性,在情况二下,需要更新每一个常规类第三系统消息。
可选地,在可选方案三中,第一指示信息还可包括:N个第四指示信息,N个第四指示信息分别对应于N个激活类第三系统消息,用于指示小区内的终端设备是否需要更新对应的激活类第三系统消息;
此时,若第四指示信息指示小区内的终端设备需要更新对应的激活类第三系统消息,则终端设备302更新对应的激活类第三系统消息;若第四指示信息指示小区内的终端设备无需更新对应的激活类第三系统消息,则终端设备302确定无需更新对应的激活类第三系统消息。
需要说明的是,以上几种可选方案仅为举例说明,实施例一在实现长DRX周期的终端设备302更新系统消息时,关键是网络设备301通过了周期性发送的,且占用的物理资源位置固定的第一系统消息来指示终端设备302是否需要更新系统消息,从而避免了采用寻呼消息指示终端设备302是否需要更新系统消息,这样,即使终端设备302无法及时读取寻呼消息,也能够实现系统消息的及时更新。
下面,以LTE系统为例,通过图6所示的流程举例说明可选方案三。
图6所示的流程中,第一系统消息为MIB消息,第二系统消息为SIB1消息,至少一个第三系统消息为SI消息,至少一个第三系统消息用于传输除了SIB1之外的其他SIB,其中包括:SI_NORM,即前述的常规类第三系统消息为,激活类第三系统消息为SI_ACT,比如:LTE系统中SIB14,主要用于实现扩展接入控制(Extended Access Barring,EAB)功能,该功能开启时,终端设备302才需要读取相关SIB。
MIB和SIB1的资源位置及重复次数固定。
SIB1以外的其他SIB包含在SI消息中。一个SI消息中可以包含一个SIB,也可以包含多个SIB。若包含多个SIB,必须是同周期、同种类的SIB。可选地,由常规类SIB组成的SI消息称为常规类SI消息,由激活类SIB组成的 SI消息成为激活类SI消息。
第二指示信息为MIB中的ValueTag;SIB1和常规SI消息每变更一次(无论一个变更周期中有几个改变),该ValueTag的值加1。
SIB1中包含SI消息的调度信息、周期以及其中分别包含哪些SIB。M个第三指示信息为SIB1中的M个SI_NORM_IND,取值为0表示对应的常规类第三系统消息未更新,取值为1表示对应的常规类第三系统消息已更新。该M个SI_NORM_IND可由bitmap实现,该bitmap包括至少M bit,每一个bit对应一个常规类第三系统消息。
N个第四指示信息为MIB中N个SI_ACT_IND,取值为0表示对应的激活类第三系统消息无需更新,取值为1表示对应的激活类第三系统消息需要更新。该N个SI_ACT_IND也可由bitmap实现,该bitmap包括至少N bit,每一个bit对应一个激活类第三系统消息。
终端设备302维护ValueTagMS,该ValueTagMS的值为上一次系统信息更新时从MIB中读取并记录下来的ValueTag的值。
其中,采用ValueTag的方式指示系统消息是否需要更新的原因是,在终端设备302休眠时,系统消息可能发生了多次变化,仅用1比特信息,如果系统消息变换了偶数次,则无法指示系统消息已经发生变化。ValueTag适用于指示第二系统消息和常规类第三系统消息或它们组合的变化情况。
而对于激活类第三系统消息,只要对应的激活指示信息置“1”,则终端设备302就要读取该激活类第三系统消息,不论是否发生变化,已经变化几次。
如图6所示,该流程包括如下步骤:
S601:处于空闲态的终端设备302从休眠状态醒来后,接收MIB,其中,可选地,终端设备302的DRX周期大于系统信息变更周期;
S602:终端设备302判断所有的SI_ACT_IND的值是否均为0;若均为0,则执行步骤S603,若存在部分SI_ACT_IND值为1,则执行步骤S604;
S603:终端设备302确定无需读取任何一个SI_ACT;
S604:终端设备302判断MIB中的ValueTag值是否变化(即比较读取的MIB中的ValueTag与自身记录的ValueTagMS值是否相等),若变化则执行步骤S606,如未变,则执行步骤S605;
S605:终端设备302根据记录的原有SIB1中的调度信息,读取SI_ACT_IND值为1的SI_ACT;
S606:终端设备302读取SIB1;
S607:终端设备302根据步骤S606中读取的SIB1中的调度信息,读取SI_ACT_IND值为1的SI_ACT;
S608:终端设备302判断MIB中的ValueTag值的变化;若没有变化,则执行步骤S609,若有变化,则执行步骤S610;
S609:终端设备302确定无需读取SIB1和任何一个SI_NORM;
S610:终端设备302判断MIB中的ValueTag值是否比自身记录的原有ValueTag值大1(即判断是否满足MIB中读取的ValueTag=ValueTagMS+1),若大1,则执行步骤S611,否则(即MIB中读取的ValueTag<ValueTagMS或MIB中读取的ValueTag>ValueTagMS+1)执行步骤S612;
S611:终端设备302读取SIB1,按照SIB1中的SI_NORM的调度信息,读取所有SI_NORM;

S615:终端设备302根据读取的SIB1中的SI_NORM_IND值为1的SI_NORM的调度信息,读取SI_NORM_IND值为1的SI_NORM。
实施例二中,终端设备302可在确定需要更新某个系统消息时,立即读取该系统消息,或者在下一个系统消息更新周期读取该系统消息。
实施例二中,针对具有长DRX周期(即DRX周期大于系统消息更新周期)的终端设备,提供了一种系统消息更新方案,该方案中,终端设备根据 第一系统消息中的第一指示信息进行系统消息更新,使得使用长DRX周期的空闲态终端设备可以及时准确地获取系统消息变更。
并且,在一种可选实现方案中,网络设备在第一系统消息中携带第二指示信息、第四指示信息,以及在第二系统消息携带第三指示信息,使得终端尽量只读取必需的系统消息,降低了终端设备的能耗。
在部分可选方案中,将第三系统消息分为常规类第三系统消息和激活类第三系统消息,第二指示信息仅指示第二系统消息和常规类第三系统消息的变更,对于激活类第三系统消息使用单独的第四指示信息指示消息变更。使得终端设备尽量只读取必需的系统消息,降低了终端能耗。
需要说明的是,实施例二可解决长DRX周期的终端设备无法及时读取寻呼消息,而导致的系统消息更新失败的问题,但实施例二也可适用于普通DRX周期的终端设备,提供了另一种系统消息更新的机制,采用该机制中的可选方案,比如:网络设备发送第二指示信息、第三指示信息和第四指示信息,可避免终端设备读取所有的系统消息,而是仅读取需要更新的系统消息,这样可降低终端设备的能耗。
【实施例三】
需要说明的是,实施例三中的部分指示信息虽然与实施例二中命名相同,但它们可能表示不同的含义,具体含义以实施例中的描述为准。
如图7所示,实施例三提供的系统消息更新流程包括如下步骤:
S701:网络设备301在小区内发送第一系统消息;
S702:终端设备302获取第一系统消息中的第一指示信息,第一指示信息用于指示与寻呼有关的系统消息是否已更新,若第一指示信息指示与寻呼有关的系统消息未更新,则执行步骤S703和步骤S704;
S703:终端设备302按照已记录的与寻呼有关的系统消息,接收网络设备301发送的寻呼消息;
S704:终端设备302根据接收的寻呼消息中与系统消息更新有关的第二指示信息进行系统消息更新。
其中,第一系统消息、第二系统消息和第三系统消息可参考前面基本概念部分的描述。
实施例三提供的系统消息更新方案,也可解决长DRX终端设备无法及时读取寻呼消息,从而导致的系统消息更新失败的问题。首先,终端设备302通过周期性发送,且占用的资源固定的第一系统消息读取第一指示信息,根据第一指示信息判断与寻呼有关的系统消息是否变更,这样,当终端设备302在确定与寻呼有关的系统消息未变更时,就可以成功接收寻呼消息,进一步再根据寻呼消息中的第二指示信息进行系统消息更新。
可选地,第二指示信息包括:第三指示信息、第四指示信息和至少一个第五指示信息;
第三指示信息,用于指示小区当前使用的第二系统消息和至少一个第三系统消息的组合的配置版本,在一个系统消息更新周期内,第二系统消息和至少一个第三系统消息中的任何一个或多个系统消息更新,配置版本变化一次;
第四指示信息,用于指示相对于最近一次配置版本变化,第二系统消息是否已更新;
一个第五指示信息对应于一个第三系统消息,用于指示相对于最近一次配置版本变化,对应的第三系统消息是否已更新。
可选地,若第三指示信息指示的配置版本与终端设备302已记录的配置版本相同,则确定无需进行系统消息更新;
若第三指示信息指示的配置版本与终端设备302已记录的配置版本不同,但两个配置版本中间没有其他不同的配置版本,则:
在第四指示信息指示相对于最近一次配置版本变化,第二系统消息已更新时,终端设备302更新第二系统消息;
在第四指示信息指示相对于最近一次配置版本变化,第二系统消息未更新时,终端设备302确定无需更新第二系统消息。
可选地,若第三指示信息指示的配置版本与终端设备302已记录的配置 版本不同,但两个配置版本中间没有其他不同的配置版本,则:
在至少一个第五指示信息中每一个第三指示信息均指示相对于最近一次配置版本变化,对应的第三系统消息并未更新时,终端设备302确定无需更新至少一个第三系统消息中的任何一个系统消息;
在至少一个第五指示信息中存在一个或多个第五指示信息,指示相对于最近一次配置版本变化,对应的第三系统消息已更新时,终端设备302针对每一个已更新的第三系统消息进行更新。
可选地,若第三指示信息指示的配置版本与终端设备302已记录的配置版本不同,且两个配置版本中间没有其他不同的配置版本,则:
终端设备302更新第二系统消息;
终端设备302按照更新后的第二系统消息中的至少一个第三系统消息的调度信息,更新每一个第三系统消息。
可选地,若第一指示信息指示与寻呼有关的系统消息已更新,则终端设备302更新第二系统消息;
获取第二系统消息中的第六指示信息和至少一个第七指示信息;
第六指示信息,用于指示小区当前使用的第二系统消息和至少一个第三系统消息的组合的配置版本,在一个系统消息更新周期内,第二系统消息和至少一个第三系统消息中的任何一个或多个系统消息更新,配置版本变化一次;
一个第七指示信息对应于一个第三系统消息,用于指示相对于最近一次配置版本变化,对应的第三系统消息是否已更新;
终端设备302根据第六指示信息和至少一个第七指示信息进行系统消息更新。
可选地,若第六指示信息指示的配置版本与终端设备302已记录的配置版本不同,但两个配置版本中间没有其他不同的配置版本,则终端设备302针对至少一个第七指示信息指示的每一个已更新的第三系统消息,对该第三系统消息进行更新;
若第六指示信息指示的配置版本与终端设备302已记录的配置版本不同,且两个配置版本中间存在其他不同的配置版本,则终端设备302针对至少一个第三系统消息中的每个系统消息进行更新。
下面,以LTE系统为例,说明实施例三提供的系统消息更新的方案。
其中,第一系统消息为MIB消息,第二系统消息为SIB1消息,至少一个第三系统消息为SI消息,至少一个第三系统消息用于传输除了SIB1之外的其他SIB。
MIB和SIB1的资源位置固定及重复次数固定。
SIB1以外的其他SIB包含在SI消息中。一个SI消息中可以包含一个SIB,也可以包含多个SIB。若包含多个SIB,必须是同周期、同种类的SIB。
第一指示信息为MIB中的ValueTagPaging,和寻呼相关的系统消息每变更一次,ValueTagPaging值加1。
第二指示信息包括寻呼消息中的第三指示信息、第四指示信息和至少一个第五指示信息,其中:
第三指示信息为ValueTag,用于指示小区当前使用的SIB1消息和至少一个SI消息的组合的配置版本,在一个系统消息更新周期内,SIB1消息和至少一个SI消息中的任何一个或多个系统消息更新,配置版本变化一次。
第四指示信息为1比特的SIB1变化指示信息,用于指示相对于上述配置版本的最近一次变化,SIB1是否已更新;
至少一个第五指示信息为K个SI_IND,取值为0表示对应的SI消息未更新,取值为1表示对应的SI消息已更新。该K个SI_IND可由bitmap实现,该bitmap包括至少K bit,每一个bit对应一个SI消息。
SIB1中包括第六指示信息和至少一个第七指示信息,其中:
第六指示信息为SIB1中的ValueTag,与寻呼消息中的ValueTag含义相同;
至少一个第七指示信息为SIB1中的K个SI_IND,含义与寻呼消息中的K个SI_IND相同。
终端设备302维护ValueTagMS和ValueTagPagingMS,该 ValueTagPagingMS的值为上一次系统消息更新时从MIB中读取并记录下来的ValueTagPaging的值,ValueTagMS的值为上一次系统消息更新时,从寻呼消息或第二系统消息中读取并记录下来的ValueTag的值。
其中,采用ValueTag的方式指示系统消息是否需要更新的原因是,在终端设备302休眠时,系统消息可能发生了多次变化,仅用1比特信息,如果系统消息变换了偶数次,则无法指示系统消息已经发生变化。
下面,以处于空闲态的终端设备302为例,说明系统消息更新的过程:
处于空闲态的终端从休眠状态醒来后,读取MIB;
下面,按照MIB中读取的ValueTagPaging的取值不同,分情况加以说明:
情况一、ValueTagPagingMS=MIB中读取的ValueTagPaging;
终端设备302接收寻呼消息,下面,区分从寻呼消息中读取的ValueTag的不同取值加以说明:
子情况一、寻呼消息中读取的ValueTag=ValueTagMS+1
在情况一的子情况一下,若从寻呼消息中读取的SIB1变化指示信息指示SIB1变更,则终端设备302读取SIB1;若寻呼消息中读取的K个SI_IND指示某一SI消息变更,则根据SIB1中的SI调度信息读取发生变更的SI消息,并设置ValueTagMS=ValueTag。
子情况二、从寻呼消息中读取的ValueTag<ValueTagMS或寻呼消息中读取的ValueTag>ValueTagMS+1
在情况一的子情况二下,终端设备302读取SIB1,根据其中SI消息调度信息,重新读取所有SI消息,并设置ValueTagMS=ValueTag。
情况二、ValueTagPagingMS≠MIB中读取的ValueTagPaging
在情况二下,终端设备302读取SIB1,根据SIB1中读取的ValueTag的取值,区分如下两种子情况:
子情况一、SIB1中读取的ValueTag=ValueTagMS+1
在情况二的子情况一下,终端设备302根据SIB1中K个SI_IND和SI调度信息,读取发生变化的SI消息,并设置ValueTagMS=SIB中读取的 ValueTag。
子情况二、SIB1中读取的ValueTag<ValueTagMS或SIB1中读取的ValueTag>ValueTagMS+1
在情况二的子情况二下,终端设备302重新读取所有SI消息,并设置ValueTagMS=SIB1中读取的ValueTag。
此外,在情况二下,终端设备302设置ValueTagPagingMS=MIB中读取的ValueTagPaging。
实施例三中,针对具有长DRX周期(即DRX周期大于系统消息更新周期)的终端设备,提供了一种系统消息更新方案,该方案中,处于空闲态的终端设备在寻呼相关的系统消息未改变的前提下,也可以通过寻呼消息获取系统消息变更信息。
并且,在实施例三的部分方案中,对终端设备读取系统消息的机制进行优化,通过在寻呼消息中携带多个指示信息,在SIB1消息中携带多个指示信息,使得终端尽量只读取必需的系统消息,以减少终端能耗。
需要说明的是,虽然实施例三可以解决长DRX周期的终端设备无法正常更新系统消息的问题,但是,对于短DRX周期的终端设备,也提供了一种新的系统消息更新的方案,能够提高系统消息更新的成功率。
【实施例四】
如图8所示,实施例四提供的系统消息更新流程包括如下步骤:
S801:网络设备301在小区内发送寻呼消息;
S802:终端设备302接收网络设备301发送的上述寻呼消息,从寻呼消息获取系统消息更新指示信息;
系统消息更新指示信息中包括:分别针对第一系统消息、第二系统消息和至少一个第三系统消息中的每一个系统消息,指示终端设备302是否需要更新该系统消息;
S803:终端设备302根据获取的系统消息更新指示信息进行系统消息更新。
其中,第一系统消息、第二系统消息和第三系统消息可参考前面基本概念部分的描述。
实施例二和实施例三均能解决长DRX周期的终端设备302的系统消息更新的问题。实施例四中,针对短DRX周期(DRX周期不大于系统消息更新周期,进一步地,系统消息更新周期可为DRX周期的整数倍)的终端设备302,提出了一种新的系统消息更新方案,其中,寻呼消息中的系统消息更新指示信息是分别针对每一个系统消息设置的,即分别针对第一系统消息、第二系统消息和至少一个第三系统消息中的每一个系统消息设置,因此可以精确地指示每一个系统消息的变化情况,这样终端设备302在进行系统消息更新时,仅需更新针对发生变化的系统消息进行更新,降低了设备能耗。
可选地,各系统消息的系统消息更新指示信息可由bitmap实现,每一比特对应一个系统消息,当一个比特为0时,表示对应的系统消息未变,当该比特为1时,表示对应的系统消息改变。
可选地,至少一个第三系统消息可包括激活类第三系统消息和常规类第三系统消息,可选地,针对第一系统消息、第二系统消息和常规类第三系统消息,当对应的系统消息更新指示信息为1时,终端设备302可在下一个系统消息更新周期中,读取对应的系统消息;针对激活类第三系统消息,当对应的系统消息更新指示信息为1时,终端设备302可立即读取该激活类第三系统消息。
【实施例五】
如图9A所示,实施例五提供的系统消息传输流程包括如下步骤:
S901:网络设备301对于要发送的每一个系统消息,确定该系统消息的发送的起始位置、发送周期和重复次数;
S902:终端设备302确定要接收的每一个系统消息的发送起始位置、发送周期和重复次数;
S903:网络设备301对于每个要发送的系统消息,按照确定的该系统消息的发送的起始位置、发送周期和重复次数,发送该系统消息,终端设备302 按照确定的每一个系统消息的发送起始位置、发送周期和重复次数,接收系统消息;
其中,一个系统消息的两次发送之间的时间间隔内,包括其他一个或多个系统消息。
实施例五提供的方案,适用于前面任何一个实施例,网络设备301的两次重复发送过程中发送其他系统消息,这样终端设备302在收完一个系统消息后,无需等待系统消息窗的到来,可以收其他系统消息,提高了系统消息更新的效率。
下面,分别介绍可选方案一和可选方案二,通过对比两种可选方案,说明实施例四的具体实现和效果。
可选方案一、网络设备301在一个SI窗口中重复发送同一个系统消息的方案;
可选方案二、网络设备301在一个系统消息的两次发送之间的时间间隔内,发送其他系统消息。
下面,参照图9B说明可选方案一。
可选方案一
可选方案一的一个应用场景是,为了实现CIoT中对于覆盖增强的要求,网络设备301需要在一个SI窗口内对同一SI消息进行重复发送。
可选方案一中,假设SI消息传输的频域资源固定,调制编码方式等也固定,只需进行时域调度。
SIB1中携带的调度信息只包括SIn,n=1,2,...,N的大小(根据系统消息SIn的大小Sn,可以得出为保证覆盖增强所需进行的重复次数Mn)以及SI消息调度的起始帧号T0以及起始子帧号t0,N为正整数。
可选方案一种,SI窗口顺序排列,中间无交叠无间隔。
在相应的窗口内对SIn,n=1,2,...,N传输Mn次所需子帧数为
Figure PCTCN2015094062-appb-000001
其中,r为固定频域资源和调制编码方式下一个子帧可以传输的比特数目。
SIn,n=1,2,...,N的起始帧号为
Figure PCTCN2015094062-appb-000002
起始子帧号为
Figure PCTCN2015094062-appb-000003
结束帧号为
Figure PCTCN2015094062-appb-000004
结束子帧号为
Figure PCTCN2015094062-appb-000005
在上述时域空间内,终端可以对SIn进行接收。其中,offseti为偏移子帧数,因为系统中有部分子帧是固定使用的,如用于传递MIB和SIB1的子帧等,需要剔除,这种规定对于终端设备302和网络设备301来说都是固定的,依系统设计可以算出具体的偏移子帧数。
结合图9B,从上述描述可见,可选方案一中,SI消息的调度在时间上是完全顺序的。对于覆盖较好的终端设备而言,可能只需接收很少的几次甚至一次重复,就可以得到某个SI。但是为了接收某一个系统消息,必须等候前面所有的系统消息重复都传输完毕。不宜于终端设备(特别是覆盖较好的终端设备)节电。因此,可选方案二给出了使用交叠SI窗口的系统消息发送方案。如图9C所示。
可选方案二
可选方案二中,以子帧为单位,系统消息SIn,n=1,2,...,N顺序排列,N为正整数。
终端设备302可以在帧号为:
Figure PCTCN2015094062-appb-000006
的数据帧中的第(t0+n+i*N-1+offsetn,i)mod10子帧上对SIn进行接收。其 中,
Figure PCTCN2015094062-appb-000007
offsetn,i为SIn的第i次重复的偏移子帧数。
采用可选方案二,对于覆盖较好的终端,可能只需要几个子帧,就可以完成对系统消息的接收。对于此类终端,可选方案二的调度方案除了能够实现资源定位以及为覆盖增强而进行足够的重复传输之外,还有利于覆盖等级较好终端的节电性能。

综上,一方面,本申请提供一种更新系统消息的方案,该方案中,网络设备在发送的第一系统消息中携带指示信息,终端设备在收到该第一系统消息后,根据该指示信息对除了第一系统消息之外的其他系统消息进行更新; 其中,第一系统消息周期性发送,且占用的物理资源位置固定。
该方案中,指示信息是在第一系统消息中发送的,而不是在寻呼消息中发送,终端设备可根据该指示信息对除了第一系统消息之外的其他系统消息进行更新,从而实现对所有系统消息的更新。与目前通过寻呼消息获知系统消息变更的方案相比,避免了终端设备的DRX周期大于系统消息变更周期,终端设备可能无法收到用于指示系统消息变更的寻呼消息,因此无法实现系统消息的更新的问题。
另一方面,本申请提供另一种更新系统消息的方案,该方案中,网络设备在发送的系统消息包括:第一系统消息、第二系统消息和至少一个第三系统消息,其中,第一系统消息周期性发送,且占用的物理资源位置固定;第二系统消息包括至少一个第三系统消息的调度信息;至少一个第三系统消息中包括与寻呼有关的系统消息;其中,网络设备在发送第一系统消息时,携带指示信息,该指示信息用于指示第三系统消息中与寻呼有关的系统消息是否已更新。若指示信息指示与寻呼有关的系统消息未更新,则终端设备按照已记录的所述与寻呼有关的系统消息,接收寻呼消息,并根据接收的寻呼消息中与系统消息更新有关的指示信息进行系统消息更新。
该方案中,由于网络设备在周期性发送的第一系统消息中指示与寻呼有关的系统消息是否已更新,如果没有更新,则终端设备仍可以按照已记录的与寻呼有关的系统消息来正常接收寻呼消息,进而从寻呼消息中获得与系统消息更新有关的指示信息,并按照从寻呼消息中获得的该指示信息更新系统消息。这样,即使DRX周期大于系统消息更新周期,由于已知与寻呼消息有关的系统消息未更新,则终端设备仍能按照已记录的与寻呼有关的系统消息正确接收寻呼消息,从而能够成功地从寻呼消息中获得与系统消息更新有关的指示信息,进而能够成功更新系统消息。
再一方面,本申请提供再一种更新系统消息的方案,该方案针对能够正常接收寻呼消息的场景,比如:系统消息更新周期为DRX周期的整数倍。该方案中,网络设备在发送寻呼消息时,寻呼消息中携带的系统消息更新指示 信息分别针对第一系统消息、第二系统消息、至少一个第三系统消息,指示第一终端设备是否需要更新该系统消息;终端设备根据系统消息更新指示信息进行系统消息更新;其中,第一系统消息周期性发送,且占用的物理资源位置固定;第二系统消息,包括至少一个第三系统消息和的调度信息。
该方案中,通过在寻呼消息携带针对每一个系统消息的指示信息,该指示信息用于指示对应的系统消息是否需要更新,终端设备可根据各个指示信息的具体情况,确定如何进行系统消息更新。比如:第二系统消息的指示信息指示第二系统消息无需更新,则终端设备在进行至少一个第三系统消息更新时,仅需根据已记录的第二系统消息进行更新,无需再重新读取第二系统消息,提高了终端设备更新系统消息的效率。
又一方面,本申请提供一种系统消息的发送方案,网络设备在发送一个系统消息时,在整个系统消息的两次发送之间的时间间隔内,发送其他一个或多个系统消息。
目前,每一个系统消息只能在一个SI窗口(SI-window)中发送,在该系统消息窗中可以发送多次,一个系统消息的SI窗口和另一个系统消息的SI窗口相邻,但一个SI窗中仅能发送一个系统消息,终端设备在一个SI窗口中收到系统消息后,必须要等到下一个SI窗口收下一个系统消息。而本申请提供的该方案中,由于在一个系统消息的两次重复发送过程中,网络设备还发送其他系统消息,这样终端设备在收完一个系统消息后,无需等待系统消息窗的到来,可以收其他系统消息,提高了系统消息更新的效率。
