这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
相关技术中,在5G系统中,随机接入分为基于竞争的随机接入和基于非竞争的随机接入。其中,基于竞争的随机接入分为4个步骤。
步骤1:用户设备(UE)发送随机接入前导码(preamble),以请求随机接入。
步骤2:基站反馈随机接入响应消息(Random Access Technology,RAR)。UE利用随机接入无线网络临时标识(Random Access Radio Network Temporary Identifier,RA-RNTI)对所述RAR进行解码。
步骤3:UE发送随机响应消息3。随机响应消息3可以包括临时小区无线网络临时标识(Temporary Cell Radio Network Temporary Identifier,TC-RNTI)。
步骤4:基站反馈随机响应消息4。随机响应消息4包括小区无线网络临时标识(Cell Radio Network Temporary Identifier,C-RNTI)。
在5G非授权频谱独立组网设计上,需要遵循LBT(先听后说)机制。即,在随机接入过程中,无论上下行,在发送消息之前,都需要监听信道。如果没有可用的时频资源,则导致时延增加,影响随机接入的效率。因此,一种可能的方案是将基于竞争的随机接入改为2步实现,即,将步骤1和步骤3中的信息合并为一个消息发送。将步骤2和步骤4中的信息合并为一个消息发送。这样,基站可能即支持2步竞争随机接入又支持4步竞争随机接入,或者仅支持4步竞争随机接入。这就带来一个问题,UE不知道应该采用哪种竞争随机接入过程。
为解决上述问题,本实施例对系统消息进行了改进,增加了指示信息,用于指示采用2步竞争随机接入的触发原因。
图1是根据一示例性实施例示出的一种传输随机接入指示信息的方法的流程图,该传输随机接入指示信息的方法用于基站等接入网设备。如图1所示,该方法包括以下步骤101-102。
在步骤101中,生成关于随机接入的指示信息;所述指示信息用于指示采用2步竞争随机接入的触发原因。
在步骤102中,向用户设备广播系统消息,所述系统消息包括所述指示信息。
本实施例中基站可以周期性的或者根据实际需要广播系统消息,即广播触发原因。以指示UE在满足触发原因时采用2步竞争随机接入。不满足触发原因时采用4步竞争随机接入。本实施例适用于支持2步竞争随机接入的UE。
在一个实施例中,所述触发原因包括业务类型和/或应用场景。
本实施例中的触发原因可以包括对时延敏感的触发原因。业务类型包括对时延敏感的业务类型,如视频直播等。应用场景包括对时延敏感的应用场景,如连接恢复等。上述触发原因均对时延要求比较高,希望尽量减少时延,因此更适于采用2步竞争随机接入。
例如,UE在有新的视频直播业务而需要发起随机接入时,则采用2步竞争随机接入。又如,UE在需要进行连接恢复而发起随机接入时,则采用2步竞争随机接入。
在一个实施例中,所述指示信息包括数值n,所述数值n是指预先配置的m种触发原因中的前n种触发原因,其中,n和m为预设参数,均为整数。
本实施例中,系统预先为基站和UE配置触发原因列表,一个实例如表1所示。
表1
序号 | 触发原因 |
1 | 视频直播 |
2 | 连接恢复 |
3 | 视频电话 |
…… | …… |
m | …… |
表1中的触发原因可以按照重要程度和频繁程度等因素进行由高到低排序。基站根据需要选择前n种触发原因。通过系统消息向UE广播指示信息n。n的最小值是0,表示没有一种触发原因适用于2步竞争随机接入,即只能采用4步竞争随机接入;最大值是m,即所有触发原因均适用于2步竞争随机接入。
UE在收到指示信息n后,查询表1,确定前n种触发原因。在满足前n种触发原因中的至少一种时,采用2步竞争随机接入。
如果表1发生变更,需要系统重新对基站和UE进行配置。
在一个实施例中,所述系统消息包括用于承载所述指示信息的指示位,指示位用来表示 数值n,所述指示位占用的比特数是根据预先配置的触发原因的总数m确定的。
本实施例中由指示位来表示指示信息。指示位所占用的比特数是根据m确定的。例如,m=8,则指示位占3位。指示位所占用的比特数可以是表示m所需的最少比特数。所述指示信息包括数值n,无论n取值是多少,指示位的长度不变。例如,m=8,n=4,则指示位的值为011。
以上介绍了基站侧的实现过程。相应的,UE侧也有改进,下面对UE侧的实现过程进行介绍。
图2是根据一示例性实施例示出的一种传输随机接入指示信息的方法的流程图,该传输随机接入指示信息的方法用于UE,其中,UE可以是移动电话,计算机,数字广播终端,消息收发设备,游戏控制台,平板设备,医疗设备,健身设备,个人数字助理等。如图2所示,该方法包括以下步骤201-202。
在步骤201中,接收基站广播的系统消息,所述系统消息包括指示信息;所述指示信息用于指示采用2步竞争随机接入的触发原因。
在步骤202中,在满足所述触发原因时,执行2步竞争随机接入。
本实施例中,基站可以周期性的或者根据实际需要广播系统消息。UE可以周期性的或临时性的接收系统消息。UE在需要进行随机接入时,确定当前随机接入的触发原因,判断该触发原因是否满足最近一次系统消息所指示的触发原因,如果满足,则执行2步竞争随机接入。如果不满足,则执行4步竞争随机接入。
在一个实施例中,所述触发原因包括业务类型和/或应用场景。
UE在需要进行随机接入时,确定当前随机接入的触发原因,该触发原因可能包括业务类型的原因和应用场景的原因。至少其中一种原因满足系统消息所指示的触发原因,便确定满足条件,则执行2步竞争随机接入。当然,也可以是业务类型的原因和应用场景的原因均满足系统消息所指示的触发原因,便确定满足条件,则执行2步竞争随机接入。
在一个实施例中,所述指示信息包括数值n,所述数值n是指预先配置的m种触发原因中的前n种触发原因,其中,n和m为预设参数,均为整数。
所述步骤202包括:步骤A。
在步骤A中,在满足所述指示信息所指示的前n种触发原因中的至少一种触发原因时,执行2步竞争随机接入。
继续前面的例子,系统预先为UE配置了表1。UE在需要进行随机接入时,确定当前随机接入的触发原因,以及确定最近一次系统消息所发送的数值n。通过该数值n查询表1,确定基站所指示的前n种触发原因。判断当前随机接入的触发原因是否满足这前n种触发原因中的至少一种,如果满足,则执行2步竞争随机接入。如果不满足,则执行4步竞争随机接入。
在一个实施例中,所述系统消息包括用于承载所述指示信息的指示位,指示位用来表示数值n,所述指示位占用的比特数是根据预先配置的触发原因的总数m确定的。
继续前面的例子,系统预先为UE配置了表1。因此UE已知总数m的取值,便可确定指 示位的长度。例如,m=8,则指示位占3位。UE在解析系统消息时便可读取已知长度的指示位,以便识别指示信息,解析出数值n。
下面结合基站和UE两侧来介绍实现过程。
图3是根据一示例性实施例示出的一种传输随机接入指示信息的方法的流程图。如图3所示,该方法包括以下步骤301-304。
在步骤301中,基站生成关于随机接入的指示信息;所述指示信息用于指示采用2步竞争随机接入的触发原因。
在步骤302中,基站向用户设备广播系统消息,所述系统消息包括所述指示信息。
在步骤303中,用户设备接收基站广播的系统消息,所述系统消息包括指示信息;所述指示信息用于指示采用2步竞争随机接入的触发原因。
在步骤304中,用户设备在满足所述触发原因时,执行2步竞争随机接入。
还可以有另外一种实现方式,系统预先为基站和UE配置了表1。基站不需要向UE广播系统消息。默认满足表1中的任一种触发原因,UE便执行2步竞争随机接入。相当于n=m的情况。参见下面的实施例。
图4是根据一示例性实施例示出的一种传输随机接入指示信息的方法的流程图,该传输随机接入指示信息的方法用于UE,其中,UE可以是移动电话,计算机,数字广播终端,消息收发设备,游戏控制台,平板设备,医疗设备,健身设备,个人数字助理等。如图4所示,该方法包括以下步骤401-402。
在步骤401中,判断是否满足预设的触发原因。
在步骤402中,在满足所述触发原因时,执行2步竞争随机接入。
本实施例中,UE在需要进行随机接入时,确定当前随机接入的触发原因,判断该触发原因是否满足系统配置的其中一种触发原因,如果满足,则执行2步竞争随机接入。如果均不满足,则执行4步竞争随机接入。
上述实施例可以根据实际需要进行自由组合。
下述为本发明装置实施例,可以用于执行本发明方法实施例。
