- the first contention detection indication is set to ‘false’
- the first contention detection indication is set to ‘true’
- the second contention detection indication is set to ‘false’
- the second contention detection indication is set to'true'.
- the terminal device when the network device only detects the MsgA preamble, but fails to detect/decode the MsgA payload, the terminal device will receive the fallbackRAR and perform Msg3 transmission according to the instructions in the fallbackRAR.
- the possible reasons for the payload not being detected/decoded successfully are:
- Interference for example, when multiple preambles correspond to one PUSCH resource unit, the network device receives payloads sent by multiple terminal devices on the same time-frequency resource, which constitutes interference with each other; or between two adjacent PUSCH resource units in the frequency domain
- the interval setting of is small, which causes interference between different PUSCH resource units;
- the transmit power cannot reach the appropriate power level.
- the power control parameter configuration is unreasonable, or the threshold setting for the access type selection is unreasonable, so that the terminal equipment with poor channel status chooses two-step random access, which results in sending MsgA payload
- the transmission power does not reach the appropriate power level.
- the two-step random access PUSCH resource link performance is poor.
- the terminal device feeds back the fallback in the two-step random access process to the network device.
- the network device further combines resource configuration, number of attempts and other information to determine the reason for the fallback of the terminal device, and then optimizes the resource configuration of PRACH and PUSCH, and adjusts Power control parameters. Combine PUSCH resource information.
- the network device can optimize the number of PUSCH resource configurations through nrofMsgA-PO-FDM and a fallback indication. For example: in a certain PUSCH configuration, nrofMsgA-PO-FDM is set to 2, and a total of N users initiate random access in this configuration and the final access is successful. According to the random access parameters reported by the N terminal devices, the network device finds that 80% of the terminal devices have undergone a fallback process before the access is successful, and the number of PUSCH resources multiplexed in the frequency domain is small.
- the network device can determine that the reason for the higher probability of backoff of the terminal device may be due to the low PUSCH resource configuration, which causes multiple preambles to be associated with a PUSCH resource unit.
- the network equipment can adjust nrofMsgA-PO-FDM, such as increasing to 6, to reduce the probability of fallback of terminal equipment.
- the network device may also optimize the packet threshold through frequencyStartMsgA-PUSCH and nrofPRBs-PerMsgA and fallback indication.
- the network equipment configures different preamble groups for the terminal equipment, where preamble groupA corresponds to PUSCH configuration #1, the frequency start point is frequencyStartMsgA-PUSCH#1, nrofPRBs-PerMsgA is 8, and preamble groupB corresponds to PUSCH configuration #2, the frequency start point It is frequencyStartMsgA-PUSCH#2, and nrofPRBs-PerMsgA is 16.
- the data volume threshold ra-MsgASizeGroupA used to select preamble group A is 48 bits.
- the terminal equipment with a total number of N selects groupA or groupB and the corresponding PUSCH resource to initiate a two-step random access, and finally access is successful.
- the network equipment found that among the terminal devices that initiated random access on the PUSCH resource corresponding to groupA, 80% of them were notified by the network to fall back, and did it on the PUSCH resource corresponding to groupB. Only 30% of random access terminal devices are notified by the network to fall back.
- the network device determines that the number of terminal devices belonging to group A is too large, and then reduces the data volume threshold ra-MsgASizeGroupA used for preamble group A selection, for example, to 40 bits to balance the user data under the two preamble group groups and reduce Probability of rollback occurrence.
- the network device may also optimize the PUSCH resource frequency domain interval through guardPeriodMsgA-PUSCH and a back-off indication. For example: in a certain PUSCH configuration, guardPeriodMsgA-PUSCH is 0, and a total of N users initiate random access in this configuration and the final access is successful. According to the random access parameters reported by N terminal devices, the network equipment finds that 80% of the terminal devices have undergone a fallback process before the access is successful, and guardPeriodMsgA-PUSCH is set to 0.
- the network device can determine that the reason for the higher probability of the fallback of the terminal device may be due to the interference between adjacent PUSCH resources in the frequency domain, which affects the successful detection/decoding of the PUSCH by the network and triggers the fallback process. Therefore, network equipment can set guardPeriodMsgA-PUSCH to reduce the probability of fallback of terminal equipment.
- the random access parameter list stored by the terminal device and whether there are random access type switching parameters can include the following situations:

- the successfully completed two-step random access process parameters and the four-step random access process parameters are stored as the third list item in the random access parameter list, including the two-step random access process parameters.
- the storage order can be in chronological order, that is, the third list item includes both the two-step random access process parameters and the four-step random access process parameters.
- the two-step random access process parameters and the four-step random access process parameters are stored in the random access parameter list as one access process, and type information needs to be introduced to distinguish two different accesses in the same list item. Entry type.
- the first list item and/or the third list item include: the received power of the reference signal referenced by the downlink path loss.
- the received power of the reference signal referenced by the downlink path loss is used to indicate the threshold for the selection of the optimized random access type.
- the reasons for the terminal's access type switching may be:
- the two-step random handover has fewer resources, or the threshold setting for the selection of the access type is unreasonable, causing more users to choose the two-step random access;
- the transmit power cannot reach the appropriate power level.
- the threshold setting for the selection of access type is unreasonable, the terminal device with poor channel status selects two-step random access, or the power control parameter configuration is unreasonable, causing the terminal device to fail Climb to an appropriate power level within the maximum number of random access attempts in two steps.
- the wireless link performance of the two-step random access resource is poor.
- the terminal equipment records and reports the type switching that occurs during the two-step random access process and the specific access information under the corresponding type, which can assist the network equipment to guess the cause of the two-step random access access problem in the terminal equipment, and then optimize the two-step random access Random access resource configuration, select the threshold of the access type and power control parameters.
- the network optimizes the access type selection threshold through RSRP (Reference Signal Receiving Power) used for downlink path loss reference and handover indication.
- RSRP Reference Signal Receiving Power
- the threshold used for random access type selection is -60dBm
- the threshold used for random access type selection is -60dBm
- select two-step random access otherwise, select four-step Random access.
- the network equipment found that half of the users who selected two-step random access had random access type switching, and the RSRP used for downlink path loss reference reported by the switched users Both are relatively low.
- the network equipment determines that because the access type selection threshold is set low, users with poor channel status choose two-step random access, and then increase the threshold for random access type selection, for example, adjust to -40dBm, Ensure that users with better channel conditions choose two-step random access to reduce the probability of handover.

基站A向安全信息成功激活的处于连接态的终端设备B发送UEInformationRequest(终端设备信息请求)消息,UEInformationRequest消息中包含基站A需要终端设备B上报的信息类型。当各个参数域对应的取值为”ture(真)”时,表示基站A需要终端设备B上报该参数域对应的信息,例如:connEstFailReportReq(连接失败报告请求):指示终端设备B是否需要上报连接失败相关信息;logMeasReportReq(注册测量报告请求):指示终端设备B是否需要上报注册测量相关信息;mobilityHistoryReportReq(移动历史报告请求):指示终端设备B是否需要上报移动历史信息;ra-ReportReq(随机接入报告请求):指示终端设备B是否需要上报随机接入过程相关信息;rlf-ReportReq(无线链路失败报告请求):指示终端设备B是否需要无线链路失败相关信息。
终端设备B通过UEInformationResponse(终端设备信息响应)消息将记录的信息反馈给基站A,响应基站A发起的UEInformationRequest。
终端设备B可以将每次随机接入尝试信息按照时间顺序记录到perRAInfoList(每个随机接入信息列表)中对于每次随机接入尝试,记录的信息包含:所选SSB(Synchronization Signal Block,同步信号块)/CSI-RS(Channel Status Indicator Reference Signal,信道状态指示参考信号)索引,所选SSB/CSI-RS对应的下行波束质量,以及竞争检测。其中,下行波束质量通过布尔值指示所选SSB/CSI-RS对应的测量结果是否高于网络侧配置的阈值;竞争检测通过布尔值指示是否在接收到的Msg4(第四消息)中检测到了其他用户的CRID(Contention Resolution Identity,竞争解决标识)。
两步随机接入(2-step Random Access Channel)过程是NR(new radio,新无线)Rel-16引入的新特性,旨在降低四步随机接入(4-step Random Access Channel)过程中的时延和信令开销。
在两步随机接入过程中,MsgA(消息A)包含有在PRACH(Physical Random Access Channel,物理随机接入信道)上传输的preamble(前导码)和在PUSCH(Physical Uplink Shared Channel,物理上行共享信道)上传输的负载信息(Msg3,第三消息),在MsgA传输后,终端设备B在配置的窗口内监听基站A的响应,如果收到基站A下发的竞争解决成功的指示,则终端设备B结束随机接入过程;如果在MsgB(消息B)中收到回退指示,则终端设备B执行Msg3的传输并监听竞争解决结果;若Msg3传输后竞争解决失败,则终端设备B继续尝试MsgA的传输。此外,基站A可以终端设备B配置两步随机接入的最大尝试次数‘N’,当终端设备B尝试了‘N’次两步随机接入后仍未接入成功,则终端设备B可以切换到四步随机接入过程继续进行接入尝试。
MsgA发送后,终端设备B侧的接收可能存在以下几种情况:
1、在接收窗口内,没有接收到基站A侧的响应;
2、在接收窗口内,接收到基站A发送的fallbackRAR(回退随机接入响应),回退到msg3的传输;
2.1、Msg3传输后,在接收窗口内没有接收到基站A的响应;
2.2、Msg3传输后,在接收窗口内接收到Msg4,通过CRID判断竞争解决失败;
2.3、Msg3传输后,在接收窗口内接收到Msg4,通过CRID判断竞争解决成功;
3、在接收窗口内,接收到基站A发送的successRAR(成功随机接入响应),通过CRID判断竞争解决成功;
4、在接收窗口内,接收到基站A发送的successRAR,通过CRID判断竞争解决失败。
但现有的随机接入上报的方法和内容都是基于四步随机接入设计的,因此现有的上报随机接入的流程并不能体现两步随机接入过程,因此无法根据两步随机接入过程的相关参数,对两步随机接入过程的参数配置进行适应的优化,存在着两步随机接入过程的参数配置优化较差的技术问题。
本申请以下具体实施方式将详细描述如何获取两步随机接入过程的相关参数,保证可以根据两步随机接入过程的相关参数,对两步随机接入过程的参数配置进行适应的优化。

上述方案1与方案2仅作实例用于说明是如何对信令结构进行优化,是实现可以是针对不同的随机接入类型,分别发送随机接入参数列表的。但是上述示例并不用于限定本申请的具体实现方式。该具体实施方式中,网络设备可以根据优化需求,有针对性地向终端设备发起上报请求。
关于第一消息的信令结构,也可以是不区分类型,请求终端设备上报全部可以上报的随机接入参数列表。具体的,包括以下可选方式:

方式3:
如图7所示,图7是本申请具体实施方式一的一种上报随机接入过程的方法的交互图。可选的,第一消息包括请求参数。
步骤1131,网络设备通过请求参数指示终端设备上报随机接入参数列表,随机接入参数列表包括两步随机接入参数列表和/或四步随机接入参数列表。对应的,终端设备发送第一响应参数和第二响应参数。

其中,当请求参数配置为真时,此时终端设备侧若存在可上报的四步随机接入参数列表,则通过UEInformationResponse中的第一响应参数,将四步随机接入参数列表上报给网络设备,否则终端设备不进行响应;终端设备侧若存在可上报的两步随机接入参数列表,则通过UEInformationResponse中的第二响应参数,将可上报的两步随机接入参数列表上报给网络设备,否则终端设备不进行响应。
上述不区分类型,请求终端设备上报全部可以上报的随机接入参数列表的具体实施方式中,终端设备接收到网络设备侧的请求后,上报全部随机接入参数列表,因此网络设备无需提前获取终端设备侧随机接入参数列表的类型。
当第一消息不区分类型,请求终端设备上报全部可以上报的随机接入参数列表时,如上述实施例所示,终端设备是分别上报两步随机接入参数列表与四步随机接入参数列表,还是一起上报两步随机接入参数列表与四步随机接入参数列表,可根据两步随机接入参数列表与四步随机接入参数列表的存储方式而定。如,当两步随机接入参数列表与四步随机接入参数列表分别存储于不同的列表项中时,则分别由不同的响应参数分别上报,如果两步随机接入参数列表与四步随机接入参数列表存储于同一个列表项中,则由一个响应参数一起上报。两步随机接入参数列表与四步随机接入参数列表的存储方式会在下面的内容中详细阐述。
可选的,该随机接入资源参数包括:
两步随机接入的随机接入机会资源的频域起始点;和/或,
两步随机接入的随机接入机会资源在频域上的复用个数;和/或,
两步随机接入的随机接入机会资源对应的子载波间隔;和/或,
物理上行共享信道资源的频域起始点;和/或,
物理上行共享信道资源在频域上的复用个数;和/或,
每个物理上行共享信道资源单元在频域上占用的物理资源块个数;和/或,
物理上行共享信道资源单元在频域上的保护间隔。
其中,两步随机接入包含用于preamble(前导码)传输的PRACH资源和用于payload(有效载荷)传输的PUSCH资源。网络设备为了优化各个BWP(Bandwidth Part,部分带宽)上的两步随机接入的资源配置,需要终端设备接入过程中对应的物理资源配置,从而根据接入性能进行相应的调整。因此,需要终端设备上报每次两步随机接入过程所用的随机接入资源参数。
图8是随机接入资源参数的示意图。如图8所示,随机接入资源参数可以包括:
两步随机接入的随机接入机会资源的频域起始点(msgA-RO-FrequencyStart),用于基于竞争的随机接入和基于非竞争的随机接入的RO(RACH Occasion,随机接入机会)资源在频域上是可以是不同的,和/或在不同时间点的配置也可以是不同的,网络设备可通过msgA-RO-FrequencyStart追溯随机接入发生的频域位置,并基于不同PRACH配置下的接入情况优化资源配置;
两步随机接入的随机接入机会资源在频域上的复用个数(msgA-RO-FDM),若RO资源配置的个数较少,可能导致碰撞概率增大;
两步随机接入的随机接入机会资源对应的子载波间隔(msgA-SubcarrierSpacing),与msgA-RO-FrequencyStart和msgA-RO-FDM共同确定PRACH资源所占用的频域范围;
物理上行共享信道资源的频域起始点(frequencyStartMsgA-PUSCH),不同的preamble group(前导码组)对应不同的PUSCH配置,不同的PUSCH配置对应不同的frequencyStartMsgA-PUSCH。网络设备可通过frequencyStartMsgA-PUSCH确定不同PUSCH配置,根据不同PUSCH配置下的接入情况,优化资源配置;
物理上行共享信道资源在频域上的复用个数(nrofMsgA-PO-FDM),若PUSCH资源单元配置的个数较少,可能导致多个preamble关联一个PUSCH资源单元,当多个终端设备在同一时频资源上发送MsgA payload时,彼此之间会产生干扰,影响网络成功检测/解码PUSCH,触发fallback(回退)流程,网络可以通过调整nfMsgA-PO-FDM,降低终端发生fallback的概率,PO为物理上行共享信道资源时机(PUSCH Occasion);
每个物理上行共享信道资源单元在频域上占用的物理资源块个数(nrofPRBs-PerMsgA),PRB(Physical Resource Block,物理资源块)个数影响终端设备可传输的数据量大小,MCS(Modulation and Coding Scheme,调制与编码策略)一定的情况下,PRB越大,终端设备可传输的数据量越大。在对preamble进行分组时,preamble group B通常对应较大的PRB。网络设备可通过nrofPRBs-PerMsgA确定不同preamble分组,并结合不同preamble group下的接入情况,优化分组标准、资源配置、功率控制参数等;
物理上行共享信道资源单元在频域上的保护间隔(guardPeriodMsgA-PUSCH),若guardPeriodMsgA-PUSCH设置过小,则利用频域上相邻两个PUSCH资源进行数据传输时可能造成彼此之间的干扰,进而导致网络设备无法成功检测/解码PUSCH,触发fallback流程,网络设备可通过配置guardPeriodMsgA-PUSCH,降低终端设备发生fallback的概率。
msgA-RO-FrequencyStart,msgA-RO-FDM和msgA-SubcarrierSpacing用于反映PRACH资源的频域信息,三者可用于共同确定PRACH在BWP上的起始位置,个数及所占频带宽度,frequencyStartMsgA-PUSCH,nrofMsgA-PO-FDM,nrofPRBs-PerMsgA和guardPeriodMsgA-PUSCH用于反映PUSCH资源的频域信息,四者可用于共同确定PUSCH资源在BWP上的起始位置,个数及所占频带宽度。
可选的,竞争检测及回退指示参数包括:
竞争检测指示,用于指示终端设备是否检测到竞争解决失败;和/或,
回退指示,用于指示终端设备是否接收到网络设备发送的回退随机接入响应。
其中,对于每次两步随机接入尝试,MsgA发送后,终端设备侧的接收可能存在以下几种情况:
1、在接收窗口内,没有接收到网络设备侧的响应;
2、在接收窗口内,接收到网络设备侧发送的fallbackRAR,回退到Msg3的传输;
2.1、Msg3传输后,在接收窗口内没有接收到网络设备侧的响应;
2.2、Msg3传输后,在接收窗口内接收到Msg4,通过CRID判断竞争解决失败;
2.3、Msg3传输后,在接收窗口内接收到Msg4,通过CRID判断竞争解决成功;
3、在接收窗口内,接收到网络设备侧发送的successRAR(成功随机接入响应),通过CRID判断竞争解决成功;
4、在接收窗口内,接收到网络设备侧发送的successRAR,通过CRID判断竞争解决失败。
配置竞争检测指示和回退指示。竞争检测指示用于指示MsgA和/或Msg3发送后,终端设备是 否能检测到竞争解决失败,回退指示用于指示终端设备是否接收到网络设备发送的fallbackRAR。
对于上述情况1、3:竞争检测指示设置为‘false(否)’,回退指示设置为‘false’;
对于上述情况4:竞争检测指示设置为‘true’,回退指示设置为‘false’;
对于上述情况2.1、2.3:竞争检测指示设置为‘false’,回退指示设置为‘true’;
对于上述情况2.2:竞争检测指示设置为‘true’;回退指示设置为‘true’。
可选的,竞争检测指示包括:
第一竞争检测指示,用于指示终端设备是否在两步随机接入过程中检测到竞争解决失败;和/或,
第二竞争检测指示,用于指示发生回退时,终端设备是否在四步随机接入过程中检测到竞争解决失败。
其中,可以只配置竞争检测指示,竞争检测指示可以包括第一检测指示和第二检测指示,第一检测指示用于指示是否在两步随机接入过程中的MsgB中检测到竞争解决失败,第二竞争检测指示用于指示发生回退时,是否在Msg4中检测到竞争解决失败,可以通过第二竞争检测指示隐式的指示终端设备发生了回退过程。
对于上述情况1、3:第一竞争检测指示设置为‘false’;
对于上述情况4:第一竞争检测指示设置为‘true’;
对于上述情况2.1、2.3:第二竞争检测指示设置为‘false’;
对于上述情况2.2:第二竞争检测指示设置为‘true’。
在两步随机接入过程中,当网络设备只检测到MsgA preamble,而未能成功检测/解码MsgA payload时,终端设备会收到fallbackRAR,并根据fallbackRAR中的指示进行Msg3的传输。导致payload没有成功检测/解码的原因可能为:
干扰,如多个preamble对应一个PUSCH资源单元的情况,网络设备在同一时频资源上接收多个终端设备发送的payload,彼此之间构成干扰;或频域上相邻两个PUSCH资源单元之间的间隔设置较小,导致不同PUSCH资源单元之间产生干扰;
发射功率无法达到合适的功率水平,如功率控制参数配置不合理,或用于接入类型选择的阈值设置不合理,使信道状态较差的终端设备选择了两步随机接入,导致发送MsgA payload的发送功率没有达到合适的功率水平。
两步随机接入PUSCH资源链路性能较差。
终端设备将两步随机接入过程中的回退情况反馈给网络设备,网络设备进一步结合资源配置、尝试次数等信息,判断终端设备发生回退的原因,进而优化PRACH和PUSCH的资源配置,调整功率控制参数。结合PUSCH资源信息。
在具体实施方式中,网络设备可以通过nrofMsgA-PO-FDM和回退指示优化PUSCH资源配置个数。例如:在某PUSCH配置下,nrofMsgA-PO-FDM设置为2,总数为N的用户在该配置发起随机接入且最终接入成功。网络设备根据N个终端设备上报的随机接入参数,发现存在80%终端设备在接入成功前发生过回退过程,且PUSCH资源在频域上的复用个数较少。网络设备据此可判断终端设备发生回退概率较高的原因可能由于PUSCH资源配置较少,导致多个preamble关联一个PUSCH资源单元,当多个终端设备在同一时频资源上发送MsgA payload时,彼此之间会产生干扰,影响网络设备成功检测/解码PUSCH,触发fallback流程。因此,网络设备可以通过调整nrofMsgA-PO-FDM,如增加到6,以降低终端设备发生fallback的概率。
在具体实施方式中,网络设备还可以通过frequencyStartMsgA-PUSCH和nrofPRBs-PerMsgA和回退指示优化分组阈值。例如:网络设备为终端设备配置不同的preamble分组,其中,preamble groupA对应PUSCH配置#1,频率起始点为frequencyStartMsgA-PUSCH#1,nrofPRBs-PerMsgA为8,preamble groupB对应PUSCH配置#2,频率起始点为frequencyStartMsgA-PUSCH#2,nrofPRBs-PerMsgA为16。用于选择preamble group A的数据量阈值ra-MsgASizeGroupA为48bits。
总数为N的终端设备根据自身待传输的MsgA paylaod大小与数据量阈值的关系,选择groupA或groupB以及对应的PUSCH资源发起两步随机接入,并最终接入成功。网络设备根据N个终端设备上报的随机接入参数,发现在groupA对应的PUSCH资源上发起随机接入的终端设备中,有80%被网络告知回退,而在与groupB对应的PUSCH资源上做随机接入终端设备只有30%被网络告知回退。网络设备据此判定属于groupA的终端设备数目过多,继而将用于preamble group A选择的数据量阈值ra-MsgASizeGroupA调小,例如调整到40bits,以平衡两个preamble group分组下的用户数据,降低回退发生概率。
在具体实施方式中,网络设备还可以通过guardPeriodMsgA-PUSCH和回退指示优化PUSCH资源频域间隔。例如:在某PUSCH配置下,guardPeriodMsgA-PUSCH为0,总数为N的用户在该配置发起随机接入且最终接入成功。网络设备根据N个终端设备上报的随机接入参数,发现存在80%终端设备在接入成功前发生过回退过程,且guardPeriodMsgA-PUSCH设置为0。网络设备据此可判断终端设备发生回退概率较高的原因可能由于频域上相邻的PUSCH资源之间的干扰,影响网络成功检测/解码PUSCH,触发fallback流程。因此,网络设备可以通过设置guardPeriodMsgA-PUSCH,以降低终端设备发生fallback的概率。
可选的,本申请的具体实施方式中,当终端设备在随机接入过程中,发生过随机接入类型切换时,该终端设备存储的随机接入参数列表以及是否存在随机接入类型切换参数,可以包括以下情形:
情形1:
图9为随机接入参数列表的示意图。如图9所示,可选的,当存在随机接入类型切换,且不同的随机接入过程参数分别存储于不同的随机接入参数列表的列表项中。例如:两步随机接入过程参数作为第一列表项存储于两步随机接入参数列表,四步随机接入过程参数作为第二列表项存储于四步随机接入参数列表中时,随机接入类型切换参数包括:
两步随机接入参数列表的切换指示,存储于第一列表项中,用于指示第二列表项的索引;和/或,
四步随机接入参数列表的切换指示,存储于第二列表项中,用于指示第一列表项的索引。
其中,随机接入类型切换参数包括:两步随机接入参数列表的切换指示和四步随机接入参数列表的切换指示。
切换指示可以设置为第一列表项和第二列表项的索引,两步随机接入参数列表的第一列表项中存储两步随机接入过程参数,当该两步随机接入发生了接入类型切换时,切换后的四步随机接入过程参数存储于四步随机接入参数列表的第二列表项,则第一列表项中的两步随机接入参数列表的切换指示设置为第二列表项的索引;第二列表项中的四步随机接入参数列表的切换指示设置为第一列表项的索引。从而将切换前后的列表项关联,可以辅助网络了解完整的随机接入过程。两步随机接入过程参数可以包括两步随机接入的资源信息,类型信息,波束信息,竞争解决信息,四步随机接入过程参数可以包括四步随机接入的资源信息,类型信息,波束信息,竞争解决信息。
该具体实施方式将两步随机接入过程参数和四步随机接入过程参数分别存储,因此可以保持各个列表中类型的统一性。
情形2:
图10为随机接入参数列表的示意图。如图10所示,可选的,当存在随机接入类型切换时,不同的随机接入过程参数作为同一列表项存储于两步随机接入参数列表或四步随机接入参数列表的同一列表项中。例如:两步随机接入过程参数与四步随机接入过程参数均作为第三列表项存储于随机接入参数列表中。
其中,当存在随机接入类型切换时,将成功完成的两步随机接入过程参数与四步随机接入过程参数均作为第三列表项存储于随机接入参数列表中,包括两步随机接入参数列表或四步随机接入参数列表,存储顺序可以按照时间顺序,即第三列表项中既包括两步随机接入过程参数,还包括四步随机接入过程参数。
该具体实施方式将两步随机接入过程参数和四步随机接入过程参数整体作为一次接入过程存储在随机接入参数列表中,需要引入类型信息区分同一列表项中的两种不同的接入类型。
可选的,第一列表项和/或第三列表项包括:下行路损参考的参考信号接收功率。
其中,该下行路损参考的参考信号接收功率用于指示优化随机接入类型选择的阈值。
终端发生接入类型切换的原因可能为:
进行两步随机切换尝试时存在严重的竞争,如两步随机切换资源较少,或用于接入类型选择的阈值设置不合理,导致较多用户选择了两步随机接入;
发射功率无法达到合适的功率水平,如用于接入类型选择的阈值设置不合理,使信道状态较差的终端设备选择了两步随机接入,或功率控制参数配置不合理,导致终端设备无法在两步随机接入最大尝试次数内攀升到合适的功率水平。
两步随机接入资源无线链路性能较差。
终端设备记录并上报两步随机接入过程中发生的类型切换以及对应类型下的具体接入信息,可以辅助网络设备推测终端设备存在两步随机接入接入问题的原因,进而优化对两步随机接入的资源配置,选择接入类型的阈值及功率控制参数。
在具体实施方式中,网络通过用于下行路损参考的RSRP(Reference Signal Receiving Power,参考信号接收功率)和切换指示优化接入类型选择阈值。例如:假设用于随机接入类型选择的阈值为-60dBm,若终端设备用于下行路损参考(downlink pathloss reference)的RSRP大于-60dBm,则选择两步随机接入,否则,则选择四步随机接入。网络设备根据终端设备上报的随机接入参数列表,发现选择了两步随机接入的用户中,有一半发生了随机接入类型切换,且发生切换的用户上报的用于下行路损参考的RSRP均比较低。网络设备基于此判定由于接入类型选择阈值设置较低,导致信道状态较差的用户选择了两步随机接入,继而将用于随机接入类型选择的阈值调大,例如调整到-40dBm,保证信道状态较好的用户去选择两步随机接入,降低切换发生的概率。
此实施方式一接收网络设备发送的第一消息,该第一消息用于指示终端设备向网络设备上报随机接入参数列表,随机接入参数列表包括两步随机接入参数列表和/或四步随机接入参数列表;根据第一消息,向网络设备上报随机接入参数列表。从而使得终端设备向网络设备上报随机接入参数列表,保证网络设备可以获取到两步随机接入的参数列表,进一步可根据两步随机接入过程的相关参数,对两步随机接入过程的参数配置进行适应的优化,解决了两步随机接入过程的参数配置优化较差的技术问题。
