Description

信息传输方法、装置及系统
本申请要求于2021年03月11日提交国家知识产权局、申请号为202110268117.8、申请名称为“一种通信方法、终端及网络设备”的中国专利申请的优先权和于2021年03月31日提交国家知识产权局、申请号为202110352707.9、申请名称为“信息传输方法、装置及系统”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域,尤其涉及信息传输方法、装置及系统。
背景技术
随着第五代(5th generation,5G)新无线(new radio,NR)系统的演进,低能力(reduced capability,REDCAP或RedCap)终端被引入。REDCAP终端具有较低的空口能力,例如,支持较小的带宽、较低的调制阶数、具有较少的天线等。
目前,对于REDCAP终端,网络设备可以在系统信息中指示是否允许REDCAP终端驻留在当前小区。进一步,还可以在系统信息中指示当前最高级别(highest ranked)的小区被禁止驻留,或者说为禁止小区时,是否允许REDCAP终端在小区选择或重选时,选择与该禁止小区相同频率的其它小区。例如,可以在系统信息下行控制信息(downlink control information,DCI)中增加指示域,用于小区禁止指示和/或同频选择或重选禁止指示。其中,系统信息DCI为采用系统信息无线网络临时标识(radio network temporary identity,RNTI)加扰的DCI。
在网络设备进行小区禁止指示和/或同频选择或重选禁止指示的情况下,该指示可能发生变更。
发明内容
本申请提供一种信息传输方法、装置及系统,能够使得终端设备及时获取最新的小区禁止信息和/或同频选择信息,降低终端设备使用错误的小区禁止信息和/或同频选择信息的概率,提高用户服务质量。
为达到上述目的,本申请采用如下技术方案:
第一方面,提供了一种信息传输方法,该方法可以由终端设备执行,也可以由终端设备的部件,例如终端设备的处理器、芯片、或芯片系统等执行,还可以由能实现全部或部分终端设备功能的逻辑模块或软件实现,本申请以终端执行该方法为例进行说明。该方法包括:终端设备接收第一信息,第一信息用于指示第一类型终端设备的小区禁止信息和/或同频选择信息;终端设备接收第二信息,第二信息用于指示第一信息发生变更。
基于该方案,在第一类型终端设备的小区禁止信息和/或同频选择信息发生变更的情况下,网络设备可以通过第二信息来指示其发生变更,从而可以使得终端设备根据第二信息获取新的小区禁止信息和/或同频选择信息,进而实现第一类型终端设备对当前网络设备配置的正确理解,降低第一类型终端设备使用错误的小区禁止信息和/或同频选择信息的概率,提高第一类型终端设备的服务质量。
第二方面,提供了一种信息传输方法,该方法可以由网络设备执行,也可以由网络设备的部件,例如网络设备的处理器、芯片、或芯片系统等执行,还可以由能实现全部或部分网络设备功能的逻辑模块或软件实现,本申请以终端执行该方法为例进行说明。该方法包括:网络设备发送第一信息,该第一信息用于指示第一类型终端设备的小区禁止信息 和/或同频选择信息;网络设备发送第二信息,该第二信息用于指示第一信息发生变更。其中,第二方面所带来的技术效果,可参考上述第一方面所带来的技术效果,在此不予赘述。
结合第二方面,在第二方面的某些实施方式中,该方法还包括:网络设备的第一功能实体生成第一信息;网络设备的第一功能实体向网络设备的第二功能实体发送第一信息。
基于该实施方式,网络设备的第二功能实体可以获得第一类型终端设备的小区禁止信息和/或同频选择信息,以便后续根据该第一类型终端设备的小区禁止信息和/或同频选择信息进行配置或控制。
结合第一方面或第二方面,在第一方面或第二方面的某些实施方式中,第一信息承载在系统信息下行控制信息中,系统信息下行控制信息为采用系统信息无线网络临时标识加扰的下行控制信息。
基于该实施方式,网络设备可以通知承载在系统信息下行控制信息中的第一类型终端设备的小区禁止信息和/或同频选择信息发生变更。
结合第一方面或第二方面,在第一方面或第二方面的某些实施方式中,第一类型终端设备的小区禁止信息指示针对第一类型终端设备当前小区是否被禁止;第一类型终端设备的同频选择信息指示当最高级别小区被禁止时,是否允许第一类型终端设备选择或重选同频小区。
基于该实施方式,能够使得终端设备根据小区禁止信息确定是否能够驻留在当前小区,或者,当最高级别小区被禁止时,是否能够选择或重选同频小区,从而使得终端设备选择合适的小区驻留,在该合适的小区中接入网络,提高终端设备的接入网络的成功率。
结合第一方面或第二方面,在第一方面或第二方面的某些实施方式中,第二信息承载在寻呼下行控制信息中,寻呼下行控制信息为采用寻呼无线网络临时标识加扰的下行控制信息;或者,第二信息承载在寻呼消息中。
基于该实施方式,可以通过网络设备对终端设备的寻呼通知终端设备第一信息发生变更。此外,在寻呼消息中承载第二信息,可以减少对现有标准的改动,例如没有改动寻呼下行控制信息的内容,从而可以更好地实现标准兼容。再者,寻呼消息可使用的比特充足,不需要占用寻呼下行控制信息中仅有的几个预留比特,从而不影响寻呼下行控制信息的可扩展性。
结合第一方面或第二方面,在第一方面或第二方面的某些实施方式中,第二信息承载在寻呼下行控制信息中,包括:第二信息承载在寻呼下行控制信息包括的短消息字段中。

基于该实施方式,在第一信息变更前,第一类型终端设备在当前小区未被禁止,从而第一类型终端能够驻留在当前小区,进而在需要发起业务时通过当前小区接入网络。之后,在第一类型终端设备在当前小区被禁止时,网络设备发送第二信息以通知禁止第一类型终端设备驻留在当前小区,可以避免已经驻留在当前小区的第一类型终端设备继续使用变更之前的小区禁止信息,误认为当前小区允许驻留,从而在需要发起业务时仍然执行接入当前小区的操作。也就是说,第一类型终端设备收到第二信息后,不会继续在当前小区接入网络,能够降低终端设备的功耗。此外,在终端设备收到第二信息后,获知当前小区被禁止,从而可以选择其他小区驻留,在需要发起业务时通过其他小区接入网络,相比于当前小区被禁止,仍然在当前小区接入导致接入失败的方案,能够降低终端设备的业务时延,提高用户体验。
结合第一方面或第二方面,在第一方面或第二方面的某些实施方式中,第一类型终端设备为低能力REDCAP终端。
第三方面,提供了一种信息传输方法,该方法可以由终端设备执行,也可以由终端设备的部件,例如终端设备的处理器、芯片、或芯片系统等执行,还可以由能实现全部或部分终端设备功能的逻辑模块或软件实现,本申请以终端执行该方法为例进行说明。该方法包括:终端设备接收第一信息,第一信息承载在系统信息下行控制信息中,系统信息下行控制信息为采用系统信息无线网络临时标识加扰的下行控制信息;终端设备接收第二信息,第二信息用于指示第一信息发生变更。

基于该方案,终端设备在获取第一类型终端设备的第一小区禁止信息和/或第一同频选择信息的情况下,还可以获取第一类型终端设备的第二小区禁止信息和/或第二同频选择信息,相比于现有技术中终端设备获取一次第一类型终端设备的小区禁止信息和/或同频选择信息的方案,能够增加终端设备获取到最新的小区禁止信息和/或同频选择信息的概率,例如,若在接收第一信息和接收第二信息之间第一类型终端设备的小区禁止信息从第一小区禁止信息变更为第二小区禁止信息,和/或,第一类型终端设备的同频选择信息从第一同频选择信息变更为第二同频选择信息,终端设备接收的第二信息即为最新的小区禁止信息和/或同频选择信息的概率,从而实现终端设备对当前网络设备配置的正确理解。
结合第五方面,在第五方面的某些实施方式中,第二信息承载在寻呼下行控制信息中,寻呼下行控制信息为采用寻呼无线网络临时标识加扰的下行控制信息;或者,第二信息承载在寻呼消息中。
基于该实施方式,在寻呼下行控制信息中承载第二信息的情况下,能够使得已经驻留在当前小区的第一类型终端设备在收到寻呼下行控制信息后立即获取新的小区禁止信息和/或同频选择信息,无需先获取系统信息下行控制信息,再从系统信息下行控制信息 中获取新的小区禁止信息和/或同频选择信息,从而降低了已驻留在当前小区的第一类型终端设备获取新的小区禁止信息和/或同频选择信息的时延。在寻呼消息中承载第二信息的情况下,可以减少对现有标准的改动,例如没有改动寻呼下行控制信息的内容,从而可以更好地实现标准兼容。

具体实施方式
为了方便理解本申请实施例的技术方案,首先给出本申请相关技术的简要介绍如下。
1、系统信息:
系统信息是网络设备在广播控制信道(broadcast control channel,BCCH)周期性广播的小区级信息。终端进行小区搜索并完成与小区的下行同步后,需要获取该小区的系统信息,以便接入该小区并在该小区内正确工作。
目前,5G NR的系统信息包括主信息块(master information block,MIB)和多个系统信息块(system information blocks,SIB)。
其中,MIB包括一些必要的物理层信息、小区禁止状态信息、以及同频重选信息。示例性的,MIB可以包括如下信息:
系统帧号:通过systemFrameNumber字段承载,用于终端设备和网络侧的同步。
调度SIB1的物理下行控制信道(physical downlink control channel,PDCCH)配置,通过pdcch-ConfigSIB1字段承载,指示调度SIB1的DCI的控制资源集合(control-resource set,CORESET)0和搜索空间配置信息。
小区禁止指示:通过cellBarred字段承载,用于指示是否允许终端驻留在当前小区。例如,当小区禁止指示为“小区禁止”时,指示不允许终端驻留在当前小区,即终端不能从当前小区接入网络;当小区进行指示为“小区未禁止”时,指示允许终端驻留在当前小区,即终端在需要发起业务时可以从当前小区接入网络。
同频重选指示:通过intraFreqReselection字段承载,指示最高级别的小区被禁止时,是否允许终端选择或重选同频的其他小区。例如,当同频重选指示为“同频重选允许”时,指示最高级别的小区被禁止时,允许终端选择或重选同频的其他小区;当同频重选指示为“同频重选不允许”时,指示最高级别的小区被禁止时,不允许终端选择或重选同频的其他小区。
需要说明的是,本申请仅列举MIB中包括的与本申请相关的信息,实际上,MIB还可以包括其他信息,例如,子载波间隔、子载波偏移、解调参考信号(demodulation reference signal,DMRS)位置信息等,可参考标准中的相关说明,在此不再赘述。
其中,SIB目前包括SIB1-SIB14共14种系统信息块,未来可能会引入更多的SIB。SIB6、SIB7、SIB8用于紧急预警通知。紧急预警通知包括地震海啸告警系统(earthquake and tsunami warning system,ETWS)通知和/或商业移动警示服务(commercial mobile alert service,CMAS)通知。ETWS包括承载在SIB6上的ETWS主(primary)通知和/或承载在SIB7上的ETWS辅(secondary)通知;CMAS通过SIB8承载。
终端在移动至某个小区后,首先获取该小区的MIB,MIB指示了调度SIB1的DCI的资源位置,终端可以进一步获取SIB1,SIB1中指示了接收其他SIB的资源位置,进而可以获取其他SIB(如SIB2-SIB14)。
小区的系统信息发生变更时,终端要重新获取变更后的系统信息以便正常地工作。除了紧急预警通知(SIB6、SIB7、SIB8),其他系统信息根据变更周期进行变更,变更周期在SIB1中配置。在一个变更周期内,网络设备广播的系统信息的内容相同;当网络设备确定改变系统信息时,在当前变更周期或当前变更周期的下一个变更周期中通过寻呼(Paging)下行控制信息(即寻呼DCI)通知终端系统信息发生变更,之后在通知变更的下一个变更周期内,网络设备改变其广播的系统信息的内容,同时终端根据寻呼DCI中的指示在通知变更的下一个变更周期内重新获取变更后的系统信息。
其中,寻呼DCI可以指采用寻呼无线网络临时标识(radio network temporary identity,RNTI)加扰的DCI。
需要说明的是,该变更周期并不影响网络设备广播系统信息的周期。通常情况下,变更周期大于系统信息的广播周期。例如,系统信息的广播周期为5ms,即网络设备每5ms广播一次系统信息。变更周期为10ms,在一个变更周期即10ms内,网络设备共广播两次系统信息,且广播的该两次系统信息的内容相同。若网络设备在当前的变更周期内确定改变系统信息,其在下一个10ms内每间隔5ms广播一次变更后的系统信息。
2、寻呼下行控制信息:
在第三代合作伙伴计划(3rd generation partnership project,3GPP)的技术指标 (technical specification,TS)38.331(即3GPP TS 38.331)中,通过寻呼DCI(即paging DCI)进行寻呼消息的调度和/或指示系统信息发生变更。其中,寻呼消息为物理下行共享信道(physical downlink shared channel,PDSCH)上承载的无线资源控制(radio resource control,RRC)消息,用于向处于RRC空闲态的终端发送呼叫请求,通知该终端进行随机接入。
其中,该寻呼DCI中包括的部分字段如下:
短消息指示(short messages indicator)字段:大小为2比特(bit),内容定义见下表1。其中,状态“00”预留,不使用,即短消息指示为“00”时,该状态无效。
表1
Figure PCTCN2022079382-appb-000001
短消息(short message)字段:大小为8bits,内容定义见下表2。如果上述短消息指示字段指示该DCI中包括寻呼消息的调度信息,不包括短消息,则该字段无效(reserved)。
需要说明的是,本申请实施例中,字段无效指该字段不承载信息,或者终端或网络设备不解析该字段,在此统一说明,下述实施例不再赘述。
表2
Figure PCTCN2022079382-appb-000002
Figure PCTCN2022079382-appb-000003
该短消息字段的第1个比特的取值为“1”时,指示承载在BCCH的系统信息有修改,也可以理解为:指示除SIB6、SIB7和SIB8之外的其他系统信息有更新,但是该比特不能指示更新的系统信息具体为哪些系统信息;该短消息内容字段的第2个比特的取值为“1”时,指示有ETWS和/或CMAS信息,也可以理解为:指示SIB6、SIB7和SIB8中的一项或多项有更新,同样,该比特不能指示SIB6、SIB7、SIB8中更新的SIB具体为哪些SIB。
频域资源分配(frequency domain resource assignment)字段:大小根据频域资源最大数确定,例如,其大小可以满足公式:
Figure PCTCN2022079382-appb-000004
其中,
Figure PCTCN2022079382-appb-000005
为频域最大资源数,或为可分配的频域资源数。如果上述短消息指示字段指示该DCI中不包括寻呼消息的调度信息,则该字段无效。
时域资源分配(time domain resource assignment)字段:大小为4bits。如果上述短消息指示字段指示该DCI中不包括寻呼消息的调度信息,则该字段无效。
虚拟资源块到物理资源块的映射(virtual resource block(VRB)-to-physical resource blocks(PRB)mapping)。
调制编码方案(modulation and coding scheme)字段:大小为5bits。如果上述短消息指示字段指示该DCI中不包括寻呼消息的调度信息,则该字段无效。
传输块缩放(transport block(TB)scaling)字段:大小为2bits。如果上述短消息指示字段指示该DCI中不包括寻呼消息的调度信息,则该字段无效。
预留比特:大小为6bits。
可以理解的是,在寻呼DCI中的短消息字段指示系统信息发生变更后,由于该字段不能指示更新的系统信息具体为哪些系统信息,从而收到该寻呼DCI的终端设备重新接收MIB,再根据MIB接收SIB1,进一步的根据SIB1接收其他SIB,从而确定发生变更的系统信息。
需要说明的是,在3GPP TS 38.212中定义了寻呼下行控制信息包括的字段,在3GPP TS 38.331中定义了寻呼下行控制信息包括的短消息字段的内容,即上述表2所示的内容。
3、寻呼时机(paging occasion,PO):
终端可以周期地接收上述寻呼DCI,该周期即为寻呼周期。终端具体接收该DCI的时刻称为寻呼时机,由网络设备确定并向终端配置。
示例性的,如图1所示,一个寻呼周期内,可以包括多个寻呼帧(paging frame,PF),每个寻呼帧包括多个PO,其中,一个PO对应一个或多个终端,即在一个PO中传输的寻呼DCI可以对一个或多个终端生效。
4、第一类型终端、第一类型终端设备的小区禁止信息、第一类型终端设备的同频选择信息:
第一类型终端设备:指具有较低空口能力的终端。作为一种示例,可以指具有比增强移动宽带(enhanced mobile broadband,eMBB)终端更低的空口能力的终端,eMBB终端 例如为智能手机。
示例性的,空口能力可以包括物理层能力和高层能力,第一类型终端设备具有较低空口能力可以包括:第一类型终端设备具有较低的物理层能力,和/或,具有较低的高层能力。第一类型终端设备具有较低的物理层能力例如可以理解为:第一类型终端设备支持较小带宽、或较低调制阶数、或较少天线、或较低多输入多输出系统(multi-input multi-output,MIMO)层数、或双工方式为半双工方式(Half Duplex Operation,HD-FDD),例如,第一类型终端最大支持20M带宽,和/或,最多支持2个接收天线。
作为一种示例,第一类型终端设备可以为REDCAP终端,REDCAP终端例如包括工业无线传感器(industrial wireless sensors)、视频监控(video surveillance)设备、可穿戴设备(Wearables)、或物联网(internet of things,IoT)中的设备(例如智能水表、智能电表)等。当然,第一类型终端设备也可以有其他名称,本申请对此不予限制。
第一类型终端设备的小区禁止信息:指示针对第一类型终端设备当前小区是否被禁止。或者说,指示是否允许第一类型终端设备驻留在当前小区。或者说,指示第一类型终端设备在当前小区是否被禁止(驻留)。可以相互替换,不予限制。
第一类型终端设备的同频选择信息:指示当最高级别的小区被禁止时,是否允许第一类型终端设备选择或重选同频小区。或者说,指示当最高级别的小区禁止第一类型终端设备驻留时,是否允许第一类型终端选择或重选同频小区。可以相互替换,不予限制。
在一些实施例中,同频选择可以指在小区选择或小区重选时选择或重选同频小区。小区选择可以是终端开机或发生无线链路失败等情况时,终端执行的小区搜索过程。小区重选可以终端的移动过程中,选择信号质量更好的小区的过程。
需要说明的是,最高级别的小区指优先级最高的小区。对于第一类型终端设备来说,在最高级别的小区为当前小区时,第一类型终端设备的同频选择信息有效,同频小区为当前小区的同频小区;否则,第一类型终端设备的同频选择信息对于第一类型终端设备是无效的。
可选的,网络设备可以在广播消息中配置多个小区或小区所在的频点,以及该多个小区中每个小区的优先级或多个频点中每个频点的优先级,终端设备可以根据该配置确定最高级别的小区。
在一些实施例中,除第一类型终端设备的小区禁止信息和第一类型终端设备的同频选择信息之外,本申请还提供第一类型终端设备的频率选择信息,该频率选择信息用于指示是否允许第一类型终端设备选择或重选指定频点(或频带)的小区。该指定频点(或频带)的小区可以与当前小区的同频小区不同。
需要说明的是,本申请下述实施例提供的第一类型终端设备的同频选择信息的特征,也可以适用于第一类型终端设备的频率选择信息。此外,第一类型终端设备的频率选择信息可以有其他名称,本申请对此不作具体限定。
可选的,根据第一类型终端设备的空口能力,可以进一步将第一类型终端设备划分为第一子类型终端设备和第二子类型终端设备,其中,第一子类型终端设备的空口能力大于第二子类型终端设备的空口能力。
可选的,第一类型终端设备的小区禁止信息可以存在如下四种情况:
1)、指示针对第一类型终端设备当前小区是否被禁止;
2)、第一类型终端设备的小区禁止信息包括第一子类型终端设备的小区禁止信 息,指示针对第一子类型终端设备当前小区是否被禁止;
3)、第一类型终端设备的小区禁止信息包括第二子类型终端设备的小区禁止信息,指示针对第二子类型终端设备当前小区是否被禁止;
4)、第一类型终端设备的小区禁止信息包括第一子类型终端设备的小区禁止信息和第二子类型终端设备的小区禁止信息,分别指示针对第一子类型终端设备当前小区是否被禁止,以及针对第二子类型终端设备当前小区是否被禁止。
其中,情况1)可以表示不进一步区分第一类型终端设备,该小区禁止信息对第一类型终端设备都生效,该情况1)也可以理解为,第一子类型终端设备和第二子类型终端设备的小区禁止信息相同。情况4)中,第一子类型终端设备和第二子类型终端设备的小区禁止信息以相同也可以不同,例如,可以指示针对第一子类型终端设备当前小区未禁止,针对第二子类型终端设备当前小区禁止,不予限制。
第一类型终端设备的同频选择信息可以存在如下四种情况:
1)、指示当最高级别的小区被禁止时,是否允许第一类型终端设备选择或重选同频小区;
2)、第一类型终端设备的同频选择信息包括第一子类型终端设备的同频选择信息,指示当最高级别的小区被禁止时,是否允许第一子类型终端设备选择或重选同频小区;
3)、第一类型终端设备的同频选择信息包括第二子类型终端设备的同频选择信息,指示当最高级别的小区被禁止时,是否允许第二子类型终端设备选择或重选同频小区;
4)、第一类型终端设备的同频选择信息包括第一子类型终端设备的同频选择信息和第二子类型终端设备的同频选择信息,分别指示当最高级别的小区被禁止时,是否允许第一子类型终端设备选择或重选同频小区,以及,当最高级别的小区被禁止时,是否允许第二子类型终端设备选择或重选同频小区。
其中,情况1)可以表示不进一步区分第一类型终端设备,该同频选择信息对第一类型终端设备都生效,该情况1)也可以理解为,第一子类型终端设备和第二子类型终端设备的同频选择信息相同。情况4)中,第一子类型终端设备和第二子类型终端设备的同频选择信息可以相同也可以不同,例如,可以指示针对第一子类型终端设备当前小区未禁止,针对第二子类型终端设备当前小区禁止,不予限制。
示例性的,以第一类型终端设备为REDCAP终端为例,根据REDCAP终端支持的最大能力可以将其分为不同的REDCAP终端。例如,REDCAP终端设备可以进一步分为高能力REDCAP终端和低能力REDCAP终端。例如,高能力REDCAP终端支持的最大接收天线数为2,和/或,支持的最大带宽为20M;低能力REDCAP终端支持的最大接收天线数为1,和/或,支持的最大带宽为20M。
其中,高能力REDCAP终端可以理解为上述第一子类型终端设备,低能力REDCAP终端可以理解为上述第二子类型终端设备。从而,REDCAP终端的小区禁止信息可以包括高能力REDCAP终端的小区禁止信息和/或低能力REDCAP终端的小区禁止信息;REDCAP终端的同频选择信息可以包括高能力REDCAP终端的同频选择信息和/或低能力REDCAP终端的同频选择信息。可参考上述描述,在此不予赘述。
目前,以第一类型终端设备为REDCAP终端为例,REDCAP终端的小区禁止信息和/或同频选择信息承载在系统信息DCI中。通过上述对系统信息以及寻呼DCI的介绍 可知,除SIB6、SIB7、SIB8之外的系统信息变更后,网络设备在当前的变更周期中通过寻呼DCI通知终端设备BCCH承载的系统信息发生改变,并未考虑系统信息DCI中的内容是否发生了改变。其中,系统信息DCI也可以称为调度SIB的DCI,可以相互替换,本申请对此不作具体限定。
也就是说,现有技术中,在REDCAP终端的小区禁止信息和/或同频选择信息承载在系统信息DCI中的情况下,若该信息发生变更,网络设备不会通知REDCAP终端小区禁止信息和/或同频选择信息发生变更,导致已驻留在小区中的REDCAP终端无法感知小区禁止信息和/或同频选择信息的变更,从而导致REDCAP终端使用未更新的小区禁止信息和/或同频选择信息。
基于此,本申请提供一种信息传输方法,能够及时通知第一类型终端设备小区禁止信息和/或同频选择信息发生变更,使得第一类型终端设备能够及时获取最新的小区禁止信息和/或同频选择信息,从而保证终端设备对网络设备当前配置的正确理解。

在一些实施例中,本申请涉及的网络设备20也可以是指集中单元(central unit,CU)或者分布式单元(distributed unit,DU),或者,网络设备20也可以是CU和DU组成的。多个DU可以共用一个CU。一个DU也可以连接多个CU。CU和DU可以理解为是对网络设备从逻辑功能角度的划分。其中,CU和DU在物理上可以是分离的,也可以部署在一起,本申请实施例对此不做具体限定。CU和DU之间可以通过接口相连,例如可以是F1接口。
CU和DU可以根据无线网络的协议层划分。例如,RRC层、SDAP层以及PDCP层的功能设置在CU中,RLC层、MAC层、PHY层等的功能设置在DU中。可以理解,对CU和DU处理功能按照这种协议层的划分仅仅是一种举例,也可以按照其他的方式进行划分。
例如,可以将CU或者DU划分为具有更多协议层的功能。例如,CU或DU还可以划分为具有协议层的部分处理功能。在一种设计中,将RLC层的部分功能和RLC层以上的协议层的功能设置在CU,将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。在另一种设计中,还可以按照业务类型或者其他系统需求对CU或者DU的功能进行划分。例如按时延划分,将处理时间需要满足时延要求的功能设置在DU,不需要满足该时延要求的功能设置在CU。在又一种设计中,CU也可以具有核心网的一个或多个功能。一个或者多个CU可以集中设置,也分离设置。例如CU可以设置在网络侧方便集中管理。DU可以具有多个射频功能,也可以将射频功能拉远设置。
在一些设计中,CU可以由CU控制面(CU control plane,CU-CP)和CU用户面(CU user plane,CU-UP)组成,CU-CP和CU-UP可以理解为是对CU从逻辑功能的角度进行划分。

需要说明的是,本申请下述实施例中各个设备之间的消息名字或消息中各参数的名字等只是一个示例,具体实现中也可以是其他的名字,本申请实施例对此不作具体限定。
如图5a所示,为本申请实施例提供的一种信息传输方法,该信息传输方法包括如下步骤:
S501a、网络设备发送第一信息。相应的,终端设备接收第一信息。
其中,第一信息用于指示第一类型终端设备的小区禁止信息和/或同频选择信息。第一类型终端设备的小区禁止信息和同频选择信息可参考前述相关说明,在此不再赘述。
可选的,接收第一信息的终端设备为第一类型终端设备,由于第一信息用于指示第一类型终端设备相关的信息,对第一信息感兴趣或有需求的终端设备需要获取第一信息,因此第一类型终端设备接收第一信息。
可以理解的,第一类型终端设备的小区禁止信息和同频选择信息为小区级别(或者说小区粒度)的信息,即每个小区都有其对应的小区禁止信息和同频选择信息。本实施例中,以终端设备在第一小区的覆盖范围内,网络设备在第一小区发送第一小区对应的第一信息为例进行说明。
也就是说,当前小区为第一小区。第一类型终端设备的小区禁止信息指示针对第一类型终端设备第一小区是否被禁止;或者说,第一类型终端设备的小区禁止信息指示是否允许第一类型终端设备驻留在第一小区;或者说,指示第一类型终端设备在第一小区是否被禁止(驻留)。在最高级别的小区为第一小区时,第一类型终端设备的同频选择信息指示当第一小区被禁止时,是否允许第一类型终端设备选择或重选第一小区的同频小区;或者说,指示当第一小区禁止第一类型终端设备驻留时,是否允许第一类型终端选择或重选第一小区的同频小区。
可选的,第一信息可以承载在系统信息下行控制信息中,该系统信息下行控制信息为采用系统信息无线网络临时标识加扰的下行控制信息。
可选的,本申请中,“系统信息下行控制信息”也可以称为“调度系统信息的下行控制信息”。也就是说,第一信息可以承载在调度系统信息的下行控制信息中。
示例性的,该系统信息下行控制信息可以为调度SIB1的DCI。也就是说,第一信息承载在调度SIB1的DCI中。
可选的,第一信息可以是网络设备周期性广播的。对于终端设备来说接收第一信息,可以是:移动至第一小区的覆盖范围后第一次接收第一信息;或者,可以是:在第一小区开机或发生无线链路失败后第一次接收第一信息;或者,可以是:在第一类型终端设备的小区禁止信息和/或同频选择信息发生变更后重新接收第一信息。本申请对终端设备接收第一信息的场景不作具体限定。
S502a、网络设备发送第二信息。相应的,终端设备接收第二信息。
其中,第二信息用于指示第一信息发生变更,即网络设备能够通知第一信息发生了变更。或者说,第二信息用于指示终端设备获取第一类型终端设备的小区禁止信息和/或同频选择信息。
可选的,第一信息承载在系统信息下行控制信息的情况下,第二信息可以理解为:用于指示终端设备获取(或读取)该系统信息下行控制信息。
可选的,第一信息包括第一类型终端设备的小区禁止信息和同频选择信息的情况下,第一信息发生变更可以为如下三种情况中的一种:
第一类型终端设备的小区禁止信息发生变更,同频选择信息未发生变更;
或者,第一类型终端设备的小区禁止信息未发生变更,同频选择信息发生变更;
或者,第一类型终端设备的小区禁止信息发生变更,同频选择信息也发生变更。
可选的,第一信息包括第一类型终端设备的小区禁止信息的情况下,第二信息用于指示第一信息发生变更,可以包括:第二信息用于指示第一类型终端设备的小区禁止信息从第一指示变更为第二指示。也就是说,第二信息能够指示第一信息的具体变更情况。
示例性的,该第一指示可以为:第一类型终端设备在当前小区未被禁止,或者说,小区未禁止;第二指示信息可以为:第一类型终端设备在当前小区被禁止,或者说,小区禁止。也就是说,第二信息用于指示第一类型终端设备的小区禁止信息从第一类型终端设备在当前小区未被禁止变更为第一类型终端设备在当前小区被禁止,或者,第二信息用于指示第一类型终端设备的小区禁止信息从小区未禁止变更为小区禁止,可以相互替换。
基于该方案,在第一信息变更前,第一类型终端设备在当前小区未被禁止,从而第一类型终端能够驻留在当前小区,从而在需要发起业务时通过当前小区接入网络。之后,在第一类型终端设备在当前小区被禁止时,网络设备发送第二信息以通知禁止第一类型终端设备驻留在当前小区,可以避免已经驻留在当前小区的第一类型终端设备继续使用变更之前的小区禁止信息,误认为当前小区允许驻留,从而在需要发起业务时仍然执行接入当前小区的操作。也就是说,第一类型终端设备收到第二信息后,不会继续在当前小区接入网络,能够降低终端设备的功耗。此外,在终端设备收到第二信息后,获知当前小区被禁止,从而可以选择其他小区驻留,在需要发起业务时通过其他小区接入网络,相比于当前小区被禁止,仍然在当前小区接入导致接入失败的方案,能够降低终 端设备的业务时延,提高用户体验。
可选的,网络设备可以在确定第一信息发生变更的情况下,发送第二信息。或者,网络设备可以在确定第一信息从第一指示变更为第二指示的情况下发送第二信息。
下面,对第二信息的具体承载方式进行说明。本申请主要提供两种承载方式,一种是第二信息承载在寻呼下行控制信息中;另一种是第二信息承载在寻呼消息中。
在第二信息承载在寻呼下行控制信息中的情况下:
在一些实施例中,第二信息可以承载在寻呼下行控制信息包括的短消息(short message)字段中。或者,第二信息可以承载在寻呼下行控制信息包括的第一字段中,该第一字段能够实现3GPP TS 38.331标准中短消息字段的功能。
作为一种实现方式,第二信息可以承载在短消息字段中已经被赋予特定功能的字段中,也就是说,可以复用短消息字段中已经被使用的字段,或者说,为短消息字段中已经被使用的字段追加新的功能。
作为一种示例,短消息字段中被复用的字段可以为系统信息变更字段(systemInfoModification),也就是说,第二信息承载在短消息字段中的系统信息变更字段中。或者,短消息字段中已经被复用的字段为第二字段,该第二字段能够实现3GPP TS 38.331标准中系统信息变更字段的功能,即第二信息承载在短消息字段中的第二字段中。
例如,系统信息变更字段设置为1时,表示第二信息,即指示第一类型终端设备的小区禁止信息和/或同频选择信息发生变更,本申请提供的一种短消息字段的内容定义可以如下表3所示。在第二信息指示第一类型终端设备的小区禁止信息从小区未禁止变更为小区禁止的情况下,本申请提供的一种短消息字段的内容定义可以如下表4所示。
需要说明的是,若复用已有字段,则被复用的字段可以指示原本指示的含义和新的含义,新的含义即用于指示第一信息发生变更。此时,如下表3所示,系统信息变更字段设置为1时,用于指示BCCH承载的除SIB6、SIB7、SIB8之外的系统信息发生变更,或者,指示第一类型终端设备的小区禁止信息和/或同频选择信息发生变更;如下表4所示,系统信息变更字段设置为1时,用于指示BCCH承载的除SIB6、SIB7、SIB8之外的系统信息发生变更,或者,指示第一类型终端设备的小区禁止信息从小区未禁止变更为小区禁止,和/或,指示第一类型终端设备的同频选择信息发生变更。

Figure PCTCN2022079382-appb-000008
可选的,第二信息承载在短消息字段中的系统信息变更字段中时,该系统信息变更字段不能指示具体是系统信息发生变更,还是第一信息发生变更,或者是第一类型终端设备的小区禁止信息从小区未禁止变更为小区禁止,从而终端设备在收到短消息字段后,若短消息字段的系统信息变更字段设置为1,可以再次接收MIB,根据MIB接收调度SIB1的DCI以接收SIB1,再根据SIB1接收其他SIB的DCI以接收其他SIB。
可选的,在终端设备再次接收MIB以及SIB的过程中,终端设备可以接收调度系统信息的DCI中承载的第三信息,该第三信息用于指示第一类型终端设备的小区禁止信息和/或同频选择信息。可以理解的是,第三信息可以认为是变更后的第一信息,承载第三信息的系统信息DCI和承载第一信息的系统信息DCI可以是同一类型的系统信息DCI,例如为调度SIB1的DCI。
其中,第二信息承载在寻呼下行控制信息包括的第一字段的实现方式,可参考第二信息承载在寻呼下行控制信息包括的短消息字段的实现方式,在此不予赘述。
基于该方案,在系统信息变更字段中承载第二信息,对现有标准的改动较小,可以更好的实现标准的兼容。
作为另一种实现方式,可以在短消息字段中定义新的字段以承载第二信息,该新的字段是在已有标准中未被使用或者说未被定义具体功能的字段。
该场景下,新定义的字段可以称为接入控制变更字段,或者,可以称为小区禁止/ 同频选择变更字段,或者,可以称为系统信息DCI变更字段。当然,其也可以有其他名称,本申请对该新定义字段的名称不作具体限定。
作为一种示例,该新的字段可以是3GPP TS 38.331标准中短消息字段中的一个或多个预留比特。例如,该新的字段可以是3GPP TS 38.331标准中短消息字段中的第4-8个比特中的一个比特,即3GPP TS 38.331标准中短消息字段中的第1-4个预留比特中的一个比特。以该新的字段称为系统信息DCI变更字段,是3GPP TS 38.331标准中短消息字段中的第4个比特为例,本申请提供的一种短消息字段的内容定义可以如下表5所示。

Figure PCTCN2022079382-appb-000009
可选的,第二信息承载在短消息字段中新定义的字段中时,若该新定义的字段设置为1,终端设备可以接收第三信息,该第三信息用于指示第一类型终端设备的小区禁止信息和/或同频选择信息。
可以理解的是,第三信息可以认为是变更后的第一信息,承载第三信息的系统信息DCI和承载第一信息的系统信息DCI可以是同一类型的系统信息DCI,例如为调度SIB1的DCI。至于终端设备是否要重新接收MIB以及SIB,可以根据系统信息变更字段来决定,例如系统信息变更字段设置为1时,重新接收MIB以及SIB,否则不接收。
基于该方案,在使用短消息中新定义的字段承载指示第一类型终端设备的小区禁止信息和/或同频选择信息发生变更的第二信息,对于第一类型终端设备来说,可以及时获取新的小区禁止信息和/或同频选择信息,另外,在MIB以及SIB承载的信息未发生变换的情况下,无需再次获取MIB以及SIB,能够节省功耗。对于非第一类型终端设备的其他终端设备,例如非REDCAP终端,无需解析该新定义的字段,也不会导致其他终端设备重复接收相同的MIB以及SIB,降低对非第一类型终端设备的影响,也节省了非第一类型终端设备的功耗。
可选的,在第二信息承载在短消息字段包括的新定义字段中的情况下,本申请提供的方法还包括:网络设备发送第四信息。相应的,终端设备接收第四信息。其中,该第四信息用于指示短消息字段中承载有第二信息,或者说,指示短消息字段中承载有用于指示第一类型终端设备的小区禁止信息和/或同频选择信息是否发生变更的信息;或者,该第四信息可以用于指示3GPP TS 38.331标准中短消息字段中的预留比特的部分或全部比特被使用。
可选的,该第四信息可以承载在寻呼下行控制信息包括的短消息指示(short message indicator)字段中,例如,将短消息指示字段的比特域设置为“00”时,表示第四信息,指示短消息字段中承载有第二信息,或者,指示短消息字段中承载有用于指示第一类型终端设备的小区禁止信息和/或同频选择信息是否发生变更的信息。该场景下,本申请提供的短消息指示字段的内容定义可以如下表6所示。
表6
Figure PCTCN2022079382-appb-000010
基于该方案,第一类型终端设备可以根据第四信息解析短消息字段的后几位比特,从而获取第一类型终端设备的小区禁止信息和/或同频选择信息是否发生变更,在发生变更的情况下,获取新的小区禁止信息和/或同频选择信息。
可选的,无论第二信息承载在短消息字段中已经被使用的字段,或者承载在短消息字段中新定义的字段,在寻呼下行控制信息中包括短消息指示字段的情况下,可以将该短消息指示字段的比特域设置为“01”或“10”,以指示寻呼下行控制信息中包括短消息字段,从而使得终端设备解析该短消息字段以获取短消息字段承载的信息。
在另一些实施例中,可以在寻呼下行控制信息中定义新的字段以承载第二信息,该新的字段是在已有标准中未被使用或者说未被定义具体功能的字段。
需要说明的是,该方案中寻呼下行控制信息中新定义的字段是与短消息字段、短消息指示字段等并列的字段,不包含于短消息字段或短消息指示字段中。
该场景下,新定义的字段可以称为接入控制变更字段,或者,可以称为小区禁止/同频选择变更字段,或者,可以称为系统信息DCI变更字段。当然,其也可以有其他名称,本申请对该新定义字段的名称不作具体限定。
作为一种示例,该新的字段可以是3GPP TS 38.212标准中寻呼下行控制信息中与短消息字段并列的一个或多个预留比特。示例性的,以该新的字段称为系统信息DCI变更字段为例,本申请提供的一种寻呼下行控制信息可以包括:
短消息指示字段;
短消息字段;
频域资源分配字段;
时域资源分配字段;
虚拟资源块到物理资源块的映射字段;
调制编码方案字段;
传输块缩放字段;
系统信息DCI变更字段;
预留比特:大小小于或等于5bits。
需要说明的是,上述列举的寻呼下行控制信息包括的字段中,系统信息DCI变更字段为必选字段,其他字段为可选字段,本申请不限定寻呼下行控制信息中除系统信息DCI变更字段之外必须包括其他字段。
基于该方案,在使用寻呼下行控制信息中新定义的字段承载指示第一类型终端设备的小区禁止信息和/或同频选择信息发生变更的第二信息,对于第一类型终端设备来说,可以及时获取新的小区禁止信息和/或同频选择信息,另外,在MIB以及SIB承载的信息未发生变换的情况下,无需再次获取MIB以及SIB,能够节省功耗。对于非第一类型终端设备的其他终端设备,例如非REDCAP终端,无需解析该新定义的字段,也不会导致其他终端设备重复接收相同的MIB以及SIB,降低对非第一类型终端设备的影响,也节省了非第一类型终端设备的功耗。
在第二信息承载在寻呼消息中的情况下:
可选的,寻呼DCI中的内容可以继承现有标准中的规定。
可选的,可以在寻呼消息中增加新的字段以承载第二信息。例如,在寻呼消息中增加1比特新字段,该1比特设置为第一值的情况下,表示第二信息,即指示第一类型终端设备的小区禁止信息和/或同频选择信息发生变更。或者,指示第一类型终端设备的小区禁止信息从小区未禁止变更为小区禁止,和/或,第一类型终端设备的同频选择信息发生变更。
示例性的,该第一值的取值可以为“0”,也可以为“1”,本申请对第一值的取值不作具体限定。
基于该方案,在寻呼消息中承载第二信息,可以减少对现有标准的改动,例如没有改动寻呼下行控制信息的内容,从而可以更好地实现标准兼容。另外,寻呼消息可使用的比特充足,不需要占用寻呼下行控制信息中仅有的几个预留比特,从而不影响寻呼下行控制信息的可扩展性。
可选的,在本申请的一种实施场景下,网络设备包括第一功能实体和第二功能实体的情况下,上述第一信息可以是第一功能实体生成的,并且网络设备的第一功能实体可以向网络设备的第二功能实体发送该第一信息。示例性的,第一功能实体可以为DU, 第二功能实体可以为CU。
也就是说,由网络设备的第一功能实体生成第一类型终端设备的小区禁止信息和/或同频选择信息的情况下,第一功能实体可以将其生成的第一类型终端设备的小区禁止信息和/或同频选择信息发送给网络设备的第二功能实体。
可选的,在第一信息发生变更的情况下,网络设备的第一功能实体与可以将变更后的第一信息(即第三信息)发送给网络设备的第二功能实体,以便第二功能实体得到最新的第一类型终端设备的小区禁止信息和/或同频选择信息。
基于该方案,网络设备的第二功能实体可以获得第一类型终端设备的小区禁止信息和/或同频选择信息,以便后续根据该第一类型终端设备的小区禁止信息和/或同频选择信息进行配置或控制。
综上,在第一类型终端设备的小区禁止信息和/或同频选择信息发生变更的情况下,网络设备可以通过第二信息来指示其发生了变更,从而可以使得第一类型终端设备根据第二信息获取更新后的小区禁止信息和/或同频选择信息,进而实现第一类型终端设备对当前网络设备配置的正确理解,降低第一类型终端设备使用错误的小区禁止信息和/或同频选择信息的概率,提高第一类型终端设备的服务质量。

可选的,第一信息用于指示第一类型终端设备的小区禁止信息和/或同频选择信息的情况下,接收第一信息的终端设备为第一类型终端设备。
需要说明的是,本申请并不限定第一信息仅用于指示第一类型终端设备的小区禁止信息和/或同频选择信息,第一信息还可以是系统信息下行控制信息中承载的其他信息,例如,第一信息可以是系统信息下行控制信息中承载的与小区的系统信息相关的信息,但是第一信息不包括调度相关的信息(例如频域资源分配、时域资源分配、虚拟资源块到物理资源块的映射、调制编码方案、冗余版本、系统信息指示域中的一个或多个),本实施例对第一信息的功能或内容不予限制。
S502b、网络设备发送第二信息。相应的,终端设备接收第二信息。

可选的,网络设备可以在确定第一信息发生变更的情况下,发送该第二信息。本实施例对网络设备发送第二信息的时机不予限制。
可选的,第一信息用于指示第一类型终端设备的小区禁止信息和/或同频选择信息的情况下,第二信息用于指示第一信息发生变更,可以包括:第二信息用于指示第一类型终端设备的小区禁止信息从第一类型终端设备在当前小区未被禁止变更为第一类型终端设备在当前小区被禁止。
可选的,第一信息是系统信息下行控制信息中承载的与小区的系统信息相关的信息的情况下,第二信息用于指示第一信息发生变更,可以包括:第二信息用于指示系统信息下行控制信息中承载的与小区的系统信息相关的信息发生变更,不用于指示系统信息下行控制信息中承载的调度相关的信息发生变更。可选的,系统信息下行控制信息中承载的调度相关的信息发生变更时,网络设备可以不通知终端设备。
可选的,第二信息可以承载在寻呼下行控制信息中;或者,第二信息可以承载在寻呼消息中。
在第二信息承载在寻呼下行控制信息中的情况下:
在一些实施例中,第二信息可以承载在寻呼下行控制信息包括的短消息(short message)字段中。或者,第二信息可以承载在寻呼下行控制信息包括的第一字段中,该第一字段能够实现3GPP TS 38.331标准中短消息字段的功能。
可选的,第二信息可以承载在短消息字段中已经被赋予特定功能的字段中,例如系统信息变更字段中;或者,可以在短消息字段中定义新的字段以承载第二信息。可参考上述步骤S502a中的相关描述,在此不予赘述。
在另一些实施例中,可以在寻呼下行控制信息中定义新的字段以承载第二信息,该新的字段是在已有标准中未被使用或者说未被定义具体功能的字段。可参考上述步骤S502a中的相关描述,在此不予赘述。
可选的,终端设备收到该第二信息后,可以进一步接收网络设备发送的第三信息,该第三信息承载在系统信息下行控制信息中。
可以理解的是,该第三信息可以认为是变更后的第一信息,承载第三信息的系统信息DCI和承载第一信息的系统信息DCI可以是同一类型的系统信息DCI,例如为调度SIB1的DCI。
基于该方案,在承载在系统信息DCI中的信息发生变更的情况下,网络设备可以通过第二信息来指示该信息发生变更,从而可以使得终端设备根据第二信息重新获取系统信息DCI,以获取更新后的信息,进而实现第一类型终端设备对当前网络设备配置的正确理解。
在图5a所示的方法中,网络设备通知第一类型终端设备的小区禁止信息和/或同频选择信息发生变更后,第一类型终端设备可以进一步获取新的第一类型终端设备的小区禁止信息和/或同频选择信息发生变更。此外,本申请还提供一种信息传输方法,该方法中,网络设备可以快速通知变更后的第一类型终端设备的小区禁止信息和/或同频选择信息。参见图6,为该信息传输方法的流程示意图,该方法包括:

其中,第二信息用于指示第一类型终端设备的第二小区禁止信息和/或第二同频选择信息。
可选的,接收第二信息的终端设备为第一类型终端设备,由于第二信息用于指示第一类型终端设备相关的信息,对第二信息感兴趣或有需求的终端设备需要获取第二信息,因此第一类型终端设备接收第二信息。
可选的,该第二信息与第一信息不同,或者说,第二信息可以理解为变更后的第一信息。

可选的,第二信息和第一信息可以承载在不同的信息或消息中。或者说,第二信息承载于与系统信息下行控制信息不同的信息中,例如,第二信息承载于与调度SIB1的DCI不同的信息中。
可选的,承载该第二信息的信息或消息可以是能够早于系统信息下行控制信息被终端设备接收的信息或消息。基于此,在将第二信息理解为变更后的第一信息的情况下,可以使得已经驻留在当前小区的第一类型终端设备及时获取新的小区禁止信息和/或同频选择信息,降低小区禁止信息和/或同频选择信息的接收时延。

在一些实施例中,第二信息可以承载在寻呼下行控制信息中,该寻呼下行控制信息为采用寻呼无线网络临时标识加扰的下行控制信息。
作为一种实现方式,可以在短消息字段中定义新的字段以承载第二信息,该新的字段是在已有标准中未被使用或者说未被定义具体功能的字段。

以3GPP TS 38.331标准中短消息字段的5个预备比特中,第1个和第2个预留比特分别承载第二小区禁止信息和第二同频选择信息,且分别称为小区禁止字段和同频选择字段为例,本申请提供的一种短消息字段的内容定义可以如下表7所示。

基于该方案,第一类型终端设备可以根据第三信息解析短消息字段的后几位比特,从而获取第一类型终端设备的小区禁止信息和/或同频选择信息是否发生变更,在发生变更的情况下,获取新的小区禁止信息和/或同频选择信息。
可选的,在第二信息承载在短消息字段包括的新定义字段中,寻呼下行控制信息中包括短消息指示字段的情况下,可以将该短消息指示字段的比特域设置为“01”或“10”,以指示寻呼下行控制信息中包括短消息字段,从而使得终端设备解析该短消息字段以获取短消息字段承载的小区禁止信息和/或同频选择信息。

该场景下,新定义的字段可以称为小区接入控制字段,或者,可以称为小区禁止/同频选择字段。当然,其也可以有其他名称,本申请对该新定义字段的名称不作具体限定。
作为一种示例,该新的字段可以是3GPP TS 38.212标准中寻呼下行控制信息中与短消息字段并列的一个或多个预留比特。示例性的,可以使用1个预留比特承载第一类型终端设备的第二小区禁止信息,或者,使用1个预留比特承载第一类型终端设备的第二同频选择信息,或者,使用2个预留比特承载第一类型终端设备的第二小区禁止信息和第二同频选择信息。可参考在短消息字段中定义新字段以承载第二信息的方式,在此不再赘述。
基于上述方案,在寻呼下行控制信息中承载第一类型终端设备的小区禁止信息和/或同频选择信息,能够使得已经驻留在当前小区的第一类型终端设备在收到寻呼下行控制信息后立即获取新的小区禁止信息和/或同频选择信息,无需先获取系统信息下行控制信息,再从系统信息下行控制信息中获取新的小区禁止信息和/或同频选择信息,从而降低了已驻留在当前小区的第一类型终端设备获取新的小区禁止信息和/或同频选择信息的时延。
在另一些实施例中,第二信息可以承载在寻呼消息中。
可选的,该实施例中,寻呼下行控制信息中的内容可以继承现有标准中的规定。
可选的,可以在寻呼消息中增加新的字段以承载第二信息。例如,在寻呼消息中增加1比特新字段,用于承载第二小区禁止信息,和/或,在寻呼消息中增加另1比特新字段,用于承载第二同频选择信息。
示例性的,在承载第二小区禁止信息的1比特设置为第一值的情况下,指示针对第 一类型终端设备当前小区未被禁止,或者说指示允许第一类型终端设备驻留在当前小区;该1比特设置为第二值的情况下,指示针对第一类型终端设备当前小区被禁止,或者说指示不允许第一类型终端设备驻留在当前小区。
在承载第二同频选择信息的1比特设置为第三值的情况下,指示当最高级别小区被禁止时,不允许第一类型终端设备选择或重选同频小区;在该1比特设置为第四值的情况下,指示当最高级别小区被禁止时,允许第一类型终端设备选择或重选同频小区。
基于该方案,在寻呼消息中承载第二信息,可以减少对现有标准的改动,例如没有改动寻呼下行控制信息的内容,从而可以更好地实现标准兼容。
可选的,在本申请的一种实施场景下,网络设备包括第一功能实体和第二功能实体的情况下,上述第一信息可以是第一功能实体生成的,并且网络设备的第一功能实体可以向网络设备的第二功能实体发送该第一信息。示例性的,第一功能实体可以为DU,第二功能实体可以为CU。
也就是说,由网络设备的第一功能实体生成第一类型终端设备的小区禁止信息和/或同频选择信息的情况下,第一功能实体可以将其生成的第一类型终端设备的小区禁止信息和/或同频选择信息发送给网络设备的第二功能实体。
可选的,在第一信息发生变更的情况下,网络设备的第一功能实体与可以将变更后的第一信息(即第二信息)发送给网络设备的第二功能实体,以便第二功能实体得到最新的第一类型终端设备的小区禁止信息和/或同频选择信息。
基于该方案,网络设备的第二功能实体可以获得第一类型终端设备的小区禁止信息和/或同频选择信息,以便后续根据该第一类型终端设备的小区禁止信息和/或同频选择信息进行配置或控制。
可以理解的是,在第一信息为系统信息下行控制信息承载的除第一类型终端设备的小区禁止信息和/或同频选择信息外的其他信息时,上述图6所示的方法也可以适用,用于尽快通知系统信息下行控制信息承载的变更后的信息。
综上,本申请通过改变现有3GPP TS 38.331和3GPP TS 38.212标准中寻呼下行控制信息的内容来通知小区禁止信息和/或同频选择信息发生变更,或者承载小区禁止信息和/或同频选择信息,使得第一类型终端设备能够获取到最新的小区禁止信息和/或同频选择,从而保证第一类型终端设备对当前网络设备配置的正确理解,降低第一类型终端设备使用错误的小区禁止信息和/或同频选择信息的概率,提高第一类型终端设备的服务质量。
可以理解的是,本申请对现有3GPP TS 38.331和3GPP TS 38.212标准中寻呼下行控制信息的内容进行改变后得到的结构,可以理解为申请提供的一种寻呼下行控制信息的结构。
以上,本申请通过通知变更或发送变更后的小区禁止信息和/或同频选择信息,使得第一类型终端设备能够获取到最新的小区禁止信息和/或同频选择。此外,本申请还提供一种方法,通过设置周期使得终端设备周期性地获取第一类型终端设备的小区禁止信息和/或同频选择信息。参见图7,为该信息传输方法的流程示意图,该方法包括如下步骤:
S701、网络设备确定第一周期。
可选的,该第一周期也可以称为第一类型终端设备的小区禁止信息和/或同频选择信息的变更周期,或者,可以称为第一类型终端设备的小区禁止信息和/或同频选择信 息的获取周期,可以相互替换,本申请对此不作具体限定。
可选的,该第一周期可以是网络设备自行确定的,该情况下,网络设备可以将该第一周期通知给终端设备,例如,网络设备可以通过系统信息将该第一周期广播给终端设备;或者,可以是协议约定的,该情况下,第一周期可以是网络设备出厂时存储在网络设备中的,网络设备确定第一周期可以理解为:网络设备读取其存储的第一周期。
可选的,在第一周期由网络设备自行确定的情况下,在不同时间或者不同情况下,网络设备确定的该第一周期的时长是可以不同的。也就是说,该第一周期是可以改变的。例如,当前第一周期可以是10ms,一段时间之后,网络设备可以将该第一周期变更为20ms。
可选的,该第一周期可以为系统信息的变更周期,即第一周期的时长与系统信息的变更周期的时长相同;或者,第一周期可以大于系统信息的变更周期,例如,第一周期为系统信息的变更周期的整数倍。
S702、网络设备在当前第一周期发送第一信息。
其中,该第一信息用于指示第一类型终端设备的第一小区禁止信息和/或第一同频选择信息。
可选的,第一信息承载在系统信息下行控制信息中,该系统信息下行控制信息为采用系统信息无线网络临时标识加扰的下行控制信息。例如,该系统信息下行控制信息为调度SIB1的DCI。
可选的,系统信息为网络设备周期性广播的,从而系统信息下行控制信息也是周期性广播的。也就是说,第一类型终端设备的第一小区禁止信息和/或第一同频选择信息是周期性广播的。为了描述方便,本申请将第一小区禁止信息和/或第一同频选择信息的广播周期称为第二周期,即网络设备按照第二周期广播第一信息。
可以理解的是,第一周期并不影响第一类型终端设备的小区禁止信息和/或同频选择信息的广播周期,即并不影响第二周期。可选的,第一周期大于第二周期。
示例性的,参见图8a,以第二周期为5ms,第一周期为10ms为例。在第一个第一周期和第二个第一周期内,即在0-10ms、以及10ms-20ms内,网络设备按照第二周期广播第一信息,即每间隔5ms广播一次第一信息,也就是说,在0ms、5ms、10ms、15ms、20ms广播第一信息。
S703、网络设备在当前第一周期之后的第一周期发送第二信息。其中,第二信息用于指示第一类型终端设备的第二小区禁止信息和/或第二同频选择信息。
可选的,该第二信息与第一信息不同,或者说,第二信息可以理解为变更后的第一信息。可参考上述步骤S602中的相关说明,在此不予赘述。
也就是说,在同一个第一周期内,网络设备发送的第一类型终端设备的小区禁止信息和/或同频选择信息相同;在不同第一周期内,网络设备发送的第一类型终端设备的小区禁止信息和/或同频选择信息可以相同也可以不同。
可选的,第二信息可以承载在系统信息下行控制信息中,例如承载在调度SIB1的DCI中。
可选的,当前第一周期之后的第一周期,可以是当前第一周期之后的下一个周期,即当前第一周期后的第一个第一周期;或者,可以是当前第一周期之后的第N个第一周期,N为大于1的正整数。
对于网络设备确定将第一信息变更为第二信息的场景:
可选的,网络设备可以是在当前第一周期确定将第一信息变更为第二信息。示例性的,基于图8a所示的示例,以当前第一周期为10ms-20ms,网络设备在10ms-15ms之间确定将第一信息变更为第二信息为例,因为当前第一周期(10ms-20ms)还未结束,而同一个第一周期发送的第一类型终端设备的小区禁止信息和/或同频选择信息相同,那么网络设备在15ms以及20ms广播的仍然为第一信息,在当前第一周期之后的第一周期内,例如当前第一周期的下一个第一周期内,即20ms-30ms内每间隔5ms广播一次第二信息。若在20ms-30ms内网络设备未变更第二信息,后续30ms-40ms内,网络设备仍然每间隔5ms广播一次第二信息,以此类推。
或者,可选的,网络设备可以是在开始发送第二信息的第一周期内确定将第一信息变更为第二信息的。
示例性的,参见图8b,以第二周期为5ms,第一周期为10ms为例。在第一个第一周期和第二个第一周期内,即在0-10ms、以及10ms-20ms内,网络设备按照第二周期广播第一信息,即每间隔5ms广播一次第一信息,也就是说,在0ms、5ms、10ms、15ms、20ms广播第一信息。假设当前第一周期为10ms-20ms,若网络设备在20ms-25ms之间确定将第一信息变更为第二信息,因为20ms-30ms内还未开始发送第一类型终端设备的小区禁止信息和/或同频选择信息,从而网络设备可以在20ms-30ms内按照第二周期发送第二信息,即在25ms、30ms分别广播第二信息。
上面对网络设备的实现进行了描述,下面对该方案中终端设备的实现进行介绍,终端设备的实现可包括如下步骤:
S704、终端设备确定第一周期。
其中,第一周期的说明可参考S701中的相关描述,在此不再赘述。
可选的,该第一周期可以是网络设备向终端设备指示的,终端设备可以通过系统信息接收网络设备广播的该第一周期;或者,该第一周期也可以是协议约定的,该情况下,第一周期可以是终端设备出厂时存储在终端设备中的,终端设备确定第一周期可以理解为:终端设备读取其存储的第一周期。
S705、终端设备按照第一周期获取第三信息。
其中,第三信息用于指示第一类型终端设备的小区禁止信息和/或同频选择信息。可以理解的是,第三信息可以是上述第一信息,在第一信息发生变更的情况下,该第三信息可以是上述第二信息。
可选的,接收第三信息的终端设备为第一类型终端设备,由于第三信息用于指示第一类型终端设备相关的信息,对第三信息感兴趣或有需求的终端设备需要获取第三信息,因此第一类型终端设备接收第三信息。
需要说明的是,终端设备对上述网络设备的内部实现并不感知。也就是说,终端设备不确定网络设备广播第二信息的时间,终端设备仅是按照第一周期获取第三信息,将第三信息指示的内容作为第一类型终端设备的最新的小区禁止信息和/或同频选择信息。
可选的,终端设备按照第一周期获取第三信息,可以理解为:终端设备每间隔第一周期的时间,获取一次第三信息。
示例性的,基于图8a或图8b所示的示例,对于终端设备来说,终端设备在0ms、10ms、20ms、30ms处获取第三信息。其中,0ms、10ms、20ms获取的第三信息用于指示第一类型终端设备的第一小区禁止信息和/或第一同频选择信息(即第一信息), 30ms处获取的第三信息用于指示第一类型终端设备的第二小区禁止信息和/或第二同频选择信息(即第二信息)。
基于该方案,本申请提供第一周期,一方面,网络设备按照第一周期变更小区禁止信息和/或同频选择信息,终端设备按照第一周期获取第一类型终端设备的小区禁止信息和/或同频选择信息,从而使得终端设备能够及时获取最新的小区禁止信息和/或同频选择信息。另一方面,无需额外的信息通知变更或额外发送变更后的小区禁止信息和/或同频选择信息,从而可以降低信令开销。再一方面,在第一周期大于系统信息的变更周期的情况下,使得终端设备获取小区禁止信息和/或同频选择信息的频率降低,从而节省了终端设备的功耗。
可以理解的是,在第一信息为系统信息下行控制信息承载的除第一类型终端设备的小区禁止信息和/或同频选择信息外的其他信息时,上述图7所示的方法也可以适用,使得终端设备能够及时获取系统信息下行控制信息承载的最新信息。

其中,第一信息用于指示第一类型终端设备的小区禁止信息和/或同频选择信息。小区禁止信息和同频选择信息可参考前述相关说明,在此不再赘述。
可选的,该网络设备的第一功能实体可以为DU。
S902、网络设备的第一功能实体向网络设备的第二功能实体发送第一信息。
可选的,该网络设备的第二功能实体可以为CU。
可选的,网络设备的第一功能实体可以通过F1接口建立请求(F1 SETUP REQUEST)消息或gNB-DU配置更新(gNB-DU CONFIGURATION UPDATE)消息向网络设备的第二功能实体发送该第一信息。当然,也可以通过其他消息发送第一信息,本申请对此不予限制。
可选的,在第一类型终端设备的小区禁止信息和/或同频选择信息发生变更的情况下,网络设备的第一功能实体也可以将变更后的小区禁止信息和/或同频选择信息发送给第二功能实体。
基于该方案,网络设备的第二功能实体可以获得第一类型终端设备的小区禁止信息和/或同频选择信息,以便后续根据该第一类型终端设备的小区禁止信息和/或同频选择信息进行配置或控制。
