Description

接入方法和装置以及通信系统 技术领域
本申请涉及通信技术领域,尤其是短距离通信。并且更具体地,涉及通信技术领域中的接入方法和装置以及通信系统。
背景技术
随着人们对个性化驾乘体验的要求的不断提高,智能座舱业务在人们的驾乘过程中发挥着越来越重要的作用。智能座舱中通常包括座舱域控制器(cockpit domain controller,CDC)、车载音响、车载麦克、车载显示器、智能终端、其他便携式设备等多种设备,CDC通过有线方式或无线方式与各种设备建立连接,并与这些设备进行通信,从而为人们提供更加丰富的娱乐、音频、视频和办公体验。
在现有的无线通信系统中,多个终端随机达到,并依次通过有限的、固定的时频资源发起随机接入,如基于竞争的随机接入,以实现与网络设备建立连接。
然而,在智能座舱中,当车辆上电后,如果座舱内的车载终端在短时间内统一在上述有限的、固定的时频资源上发起基于竞争的随机接入,就会出现严重的资源碰撞,因此,无法实现车载终端的批量接入。
发明内容
本申请实施例提供一种接入方法和装置以及通信系统,能够支持终端的批量接入。
第一方面,本申请实施例提供一种接入方法。所述方法可以应用于通信系统,该通信系统包括网络控制装置和多个终端。该方法包括:所述网络控制装置发送资源配置信息,所述资源配置信息用于配置用于所述多个终端接入网络的第一时频资源;所述多个终端中的至少一个终端在所述第一时频资源上,向所述网络控制装置发送所述至少一个终端中每个终端的接入信息,所述终端的接入信息包括第一身份信息或状态信息中的至少一项,所述第一身份信息用于标识所述终端,所述状态信息用于指示所述终端的状态;所述网络控制装置在所述第一时频资源上,接收所述至少一个终端中每个终端的接入信息。具体的,上述“接入”为初始接入。

需要说明的是,在所述网络控制装置发送资源配置信息之前,该多个终端处于非连接态,即该多个终端均未接入该网络控制装置、或未与该网络控制装置建立连接。
还需要说明的是,本申请实施例中所述的非连接态可以包括空闲态、去激活态。
也就是说,终端所处的状态可以包括连接态和非连接态,其中,非连接态可以包括空 闲态、去激活态。
可选地,在所述网络控制装置发送资源配置信息之前,所述网络控制装置需要先确定所述第一时频资源。
在一种可能的实现方式中,该第一时频资源是指该网络控制装置所在通信域中可用的时频资源。相比现有的随机接入方式中预配置的有限的、固定的时频资源,该可用的时频资源可以提供更充足的资源以满足多个终端的群接入。
例如:该第一时频资源可以包括该网络控制装置所在通信域中可用的全部时频资源。
需要说明的是,本申请实施例中所述的可用的全部时频资源,或者可以称为可以用于初始接入的全部时频资源。进一步,该全部时频资源占用至少一个时域资源单元(或者说第一时域长度)和至少一个频域资源单元(或者第一频域带宽)。由于在车辆刚上电的情况下,尚未有车载设备接入,因此上述可用的全部时频资源可以作为接入资源使用。

在现有的无线通信系统中,终端采用随机接入的方式,如基于竞争的随机接入方式接入网络设备。由于各终端的达到是随机的,接入需求服从泊松分布,即各终端的接入请求在时间上是近似平均的,在各终端请求随机接入的时候,系统中还有正在服务的其它终端。
网络设备通常将当前可用的时频资源中有限的、固定的一部分时频资源分配用于终端进行随机接入,如可用的时域时隙(slot)中固定的2个符号(symbol)以及可用的频域带宽中固定的2个子载波(subcarrier)用于随机接入,除此之外,其它可用的时频资源都用来维持和保障其它终端的业务。
然而,当车辆上电后,可能存在座舱的通信域内的多个车载终端在短时间内统一向该CDC发起接入请求的场景,在上述终端的批量接入或群接入的场景下,如果该多个车载终端采用现有的随机接入方法,通过固定且有限的、用于随机接入的时频资源进行基于竞争的随机接入,可能会发生严重的资源冲突,导致无法实现车载终端的批量接入或群接入。
本申请实施例提供一种接入方法和装置,能够实现上述场景下终端的批量接入或群接入。
图3示出了本申请实施例提供的接入方法200的示意性流程图,该方法200应用于如图1所示通信系统100,如通信系统100中的通信域110,并适用于车辆的座舱中。
S210,网络控制装置发送资源配置信息,所述资源配置信息用于配置用于多个终端接入网络的第一时频资源。相应地,所述多个终端接收来自所述网络控制装置的资源配置信息。具体的,所述资源配置信息用于配置多个终端进行初始接入。
可选地,该网络控制装置和该多个终端可以为多种形态,本申请实施例对此不作限定。
在一种可能的实现方式中,该网络控制装置可以为车舱中的CDC,该多个终端可以为该车舱内的多个车载终端,车辆制造商将该CDC和该多个车载终端集成于该车舱所在的车辆中。
需要说明的是,在S210之前,该多个终端处于非连接态,即该多个终端均未接入该网络控制装置、或未与该网络控制装置建立连接。
还需要说明的是,本申请实施例中所述的非连接态可以包括空闲态或去激活态。
也就是说,终端所处的状态可以包括连接态和非连接态,其中,非连接态可以包括空闲态或去激活态。
下面将分别介绍一下上述连接态、空闲态和去激活态。
(1)连接态,或称为无线资源控制(radio resource control,RRC)连接态,是指终端与网络控制装置建立了网络连接,可以进行数据传输。
(2)空闲态,或称为RRC空闲态,是指终端与网络控制装置未建立网络连接,且该网络控制装置没有存储该终端的上下文信息。也就是说,如果该终端需要从空闲态进入连接态,则需要发起网络连接建立过程。
(3)去激活态,或称为RRC去激活态,是指终端之前进入了连接态,然后网络控制装置挂起了网络连接,但是该网络控制装置保存了该终端的上下文信息。也就是说,如果 该终端需要从去激活态再次进入连接态,则需要发起网络连接恢复过程(或称为网络连接重建立过程)。需要说明的是,网络连接恢复过程相对于网络连接建立过程来说,时延更短,信令开销更小。但是网络控制装置需要保存该终端的上下文,会占用网络控制装置的存储开销。
可选地,在S210之前,所述网络控制装置需要先确定所述第一时频资源。
在一种可能的实现方式中,该第一时频资源是指该网络控制装置所在通信域中可用的时频资源。相比现有的随机接入方式中预配置的有限的、固定的时频资源,该可用的时频资源可以提供更充足的资源以满足多个终端的群接入。
例如:该第一时频资源可以包括该网络控制装置所在通信域中可用的全部时频资源。
需要说明的是,本申请实施例中所述的可用的全部时频资源,或者可以称为可以用于初始接入的全部时频资源。进一步,该全部时频资源占用至少一个时域资源单元(或者说第一时域长度)和至少一个频域资源单元(或者第一频域带宽)。由于在车辆刚上电的情况下,尚未有车载设备接入,因此上述可用的全部时频资源可以作为接入资源使用。
可选地,上述至少一个时域资源单元(或者说第一时域长度)可以是连续的或离散的,上述至少一个频域资源单元(或者说第一频域带宽)也可以是连续的或离散的,本申请实施例对此不作限定。
需要说明的是,上述时域资源单元可以理解为时域上调度的粒度大小,例如最小粒度,上述频域资源单元可以理解为频域上调度的粒度大小。
具体的,该时域资源单元可以为但是不限于时隙(slot)或帧,其中,帧或slot中包含若干符号(symbol)。例如,上述符号为正交频分复用(orthogonal frequency division multiplexing,OFDM)符号。该频域资源单元可以为但是不限于一个或多个子载波等。
需要说明的是,所述可用的全部时频资源或者用于初始接入的全部时频资源为通信域中可用的、用于传输数据的全部时频资源,即数据信道的时频资源。
可选地,该用于初始接入的全部时频资源中的时域资源可以是有限长度的。
在一种可能的实现方式中,该网络控制装置在该多个终端通过该用于初始接入的全部时频资源完成初始接入之后,可以发送用于指示初始接入已完成的系统广播消息。相应地,后续有接入需求的终端则按照现有的随机接入方法,在预配置的、有限的、用于随机接入的时频资源上进行随机接入。
还需要说明的是,所述可用的全部时频资源或者用于初始接入的全部时频资源不包括通信域中可用的、用于承载系统控制面开销的符号(如承载导频信号,同步信号,控制信号,广播信号等的符号)的时频资源。
也就是说,所述可用的全部时频资源或者用于初始接入的全部时频资源不包括用于控制信息或者控制信号的时频资源,这里的控制信息可以包括用于调度数据的控制信令,如广播信道信息、数据反馈信息等,这里的控制信号可以包括同步信号、接入信道信号、SRS、DMRS等。
采用本申请实施例提供接入方法中,在群接入或批量接入的场景下,由于车辆刚上电,该网络控制装置所在通信域中还没有接入任何的终端,因此,该网络控制装置可以计算或者确定出当前通信域中可用的全部时频资源,并将全部时频资源都分配给这些终端进行群接入或批量接入,能够满足群接入或批量接入的需求,同时可以降低多个终端接入时可能 产生资源冲突的概率。
可选地,该网络控制装置可以通过多种方式确定所述第一时频资源,本申请实施例对此不作限定。
在一种可能的实现方式中,以该网络控制装置和该多个终端属于第一通信域为例,该网络控制装置可以接收来自第二通信域中的第二网络控制装置的系统广播消息,系统广播消息用于指示该第二通信域所占用的全部时频资源;该网络控制装置可以根据该第二通信域所占用的全部时频资源,确定该第一时频资源,其中,该第二通信域所占用的全部时频资源与该第一时频资源不同。
可选地,该第一通信域与该第二通信域可以属于同一车舱或不同车舱,本申请实施例对此不作限定。
需要说明的是,上面仅以该网络控制装置根据第二通信域所占用的全部时频资源,确定该第一时频资源为例,介绍该网络控制装置确定该第一时频资源的方式,但本申请实施例不限于此。
可选地,该网络控制装置还可以根据多个通信域所占用的全部时频资源,确定该第一时频资源,该多个通信域包括该第二通信域,本申请实施例对此不作限定。
在另一种可能的实现方式中,该网络控制装置可以通过更高层的网络设备获取该第一时频资源,该更高层的网络设备能够计算并为每个网络控制装置分配该每个网络控制装置所在通信域可用的全部时频资源。可选的,所述网络控制装置接收来自另一网络设备的指示信息,所述指示信息用于指示所述第一时频资源。
例如,以该网络控制装置为接入网设备为例,该网络控制装置可以向核心网设备发送资源请求,该资源请求用于请求当前该网络控制装置可用的全部时频资源;接收来自该核心网设备发送的资源信息,该资源信息用于指示该第一时频资源。
可选地,S210中,该网络控制装置可以通过多种方式发送该资源配置信息,本申请实施例对此不作限定。
在第一种可能的实现方式中,该网络控制装置可以向该多个终端中的每个终端发送该资源配置信息。
在第二种可能的实现方式中,该网络控制装置可以发送组播消息,该组播消息包括该资源配置信息和组播地址。
需要说明的是,组播地址是指一组终端的地址,针对这个地址发送的消息,可以被这组终端识别并接收。
例如:该多个终端包括终端1和终端2,该终端1和终端2属于第一终端组,该网络控制装置发送的组播消息中包括该资源配置信息和该第一终端组的组播地址;相应地,该终端1和终端2接收根据所在组对应的组播地址接收该组播消息。
可选地,该组播消息还可以包括终端数量信息,该终端数量信息用于指示该组播地址对应的终端数量。
在第三种可能的实现方式中,该网络控制装置可以发送系统广播消息,该系统广播消息包括该资源配置信息。
例如:该系统广播消息可以为主信息块(master information block,MIB)消息或系统信息块(system information block,SIB)消息。
采用本申请实施例提供的接入方法,该网络控制装置将该资源配置信息承载于组播消息或系统广播消息中,能够减少传输时延,从而提高接入效率。

需要说明的是,由于该网络控制装置与该第一终端可以是同一个车辆制造商生产的, 因此,在车辆制造商可以为网络控制装置预先配置用于确定该第一终端对应的第二时频资源的相关信息(如该第一终端的第二身份信息、该第一终端对应的第二时频资源的资源大小、该至少一个数值等)以及第一终端对应的第二时频资源的计算规则,因此,该网络控制装置无需与该第一终端进行额外的信令交互,以获取用于确定该第一终端对应的第二时频资源时所需要的相关信息,能够减少信令的开销,从而降低接入时延。

也就是说,该网络控制装置可以采用与第一终端类似的方法,确定该第一终端对应的第二时频资源。
但是,在上述第一种可能的实现方式中,由于M是该第一终端选择的一个随机数,该网络控制装置无法得知该第一终端随机选择了哪个随机数,因此,该网络控制装置需要在该第一时频资源上接收来自该第一终端上报的接入信息。

需要说明的是,本申请实施例中网络控制装置可以为所属通信域内的每个终端配置软地址,该每个终端的软地址在该通信域内能够唯一标识该每个终端。
在一种可能的实现方式中,该第一终端的软地址可以为该第一终端上一次接入时,该网络控制装置为该第一终端分配的地址。

相应地,由于上述第二种或第三种可能的实现方式中,该网络控制装置可以根据预先配置用于确定该第一终端对应的第二时频资源的相关信息,确定M。因此,该网络控制装置在该第一时频资源上接收该第一终端的接入信息,可以包括:该网络控制装置在该第一终端对应的第二时频资源上,接收该第一终端的接入信息。
采用上述选择资源块的方法,由于该网络控制装置预先配置有每个终端的第二身份信息,通过合理设置该第一数值,能够有效错开不同的终端对应的第二时频资源,即保证不同的终端对应的第二时频资源互不重叠,从而降低产生资源冲突的概率。
可选地,该多个终端中可以存在至少两个终端的属性不同,该网络控制装置可以通过该资源配置信息为不同属性的终端配置不同的子时频资源,其中,该第一时频资源包括不同属性的终端对应的子时频资源。

在另一种可能的实现方式中,可以按照终端的设备类型划分终端的设备优先级。
例如:显示器的设备优先级高于音响的设备优先级,音响的设备优先级高于麦克风的设备优先级。
可选地,该网络控制装置可以通过以下几种方式,为不同属性的终端配置不同的子时频资源。

在一种可能的实现方式中,以该多个终端包括第一属性的第一终端和第二属性的第二终端,该第一终端对应该第一时频资源中的第一子时频资源,该第二终端对应该第一时频资源中的第二子时频资源为例,则S220可以为:该第一终端在该第一子时频资源上,向该网络控制装置发送该第一终端的接入信息;相应地,该网络控制装置在该第一子时频资源上,接收该第一终端的接入信息。
需要说明的是,不同属性的终端对应的子时频资源的时域资源或频域资源中的至少一种资源不同。
也就是说,该第一子时频资源与该第二子时频资源的时域资源或频域资源中的至少一种资源不重叠。
采用本申请实施例提供的接入方法,该网络控制装置针对不同的属性的终端配置不同的子时频资源,使得不同属性的终端通过所属的属性对应的子时频资源进行接入,能够降低不同属性的终端之间接入时产生资源冲突的概率。
需要说明的是,该第一终端在该第一子时频资源上,确定该第一终端对应的第二时频资源的方法可以参照上面所述的在第一时频资源上,确定该第一终端对应的第二时频资源的方法,区别仅在于,将上述第一时频资源的资源大小替换为该第一子时频资源的资源大小,为避免重复,此处不再赘述。

在第二种可能的实现方式中,该网络控制装置可以根据该至少一个第一目标终端中每个第一目标终端的接入信息,确定该至少一个第一目标终端接入成功。
例如,如果终端1和终端2恰好选择了相同的资源块,分别发送了各自的接入信息,网络控制装置可能只能成功解码其中的一个终端的接入信息,或者解码失败,没有获取任何接入信息,这样一来,只有网络控制装置成功解码的接入信息对应的终端接入成功。
