Description

一种通信方法及相关设备
本申请要求于2018年08月25日提交中国国家知识产权局、申请号为201810976575.5、发明名称为“一种通信方法及相关设备”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
本申请涉及通信技术领域，并且更具体地，涉及一种随机接入的通信方法及相关设备。
背景技术
随机接入过程一般是终端设备在接入网络时需要执行的第一个流程。因此，随机接入过程使用的配置参数对随机接入的性能以及系统的性能有着关键的影响。
随机接入配置参数决定了随机接入的冲突概率，而随机接入的冲突概率又是影响呼叫建立时延，上行失步的恢复时延和切换时延的关键因素。随机接入的冲突概率同时还影响呼叫建立的成功率以及切换成功率。不合适的随机接入配置还有可能导致较低的前导码检测率，使出现系统覆盖受限的问题。
长期演进(long term evolution，LTE)移动通信系统的随机接入配置参数优化的主要功能可以包括：分组随机接入信道(packet random access channel，PRACH)资源配置的优化；随机接入通道(random access channel，RACH)资源配置优化，可以包括随机接入前导码(preamble)分组的优化，随机接入功率控制参数的优化。
第五代通信(fifth generation,5G)中存在波束和补充上行载波，还存在控制单元(control unit，CU)和分布式单元(distributed unit，DU)，无线接入网设备可以按照协议层划分为至少一个分布式单元和连接到该至少一个分布式单元的至少一个控制单元。该分布式单元可以包括无线链路控制(radio link control，RLC)层功能，MAC层功能和物理(physical，PHY)层功能。该控制单元可以包括分组数据汇聚层协议(packet data convergence protocol，PDCP)层功能，业务数据适配协议(service data adaptation protocol，SDAP)层功能以及无线资源控制(radio resource control，RRC)层功能，其中，CU和DU组成的网络架构可以称之为CU-DU架构。
目前尚没有好的机制来及时准确地进行随机接入信道优化。
发明内容
在随机接入过程中，由于来自邻接小区的物理上行共享信道(physical uplink shared channel，PUSCH)的干扰，随机接入信道的负载(可以包括呼叫到达率，入切换率，跟踪区域更新)的变化，PUSCH信道的负载的变化，网络配置的改变(如天线倾角的优化，小区发射功率的改变)等，导致随机接入过程中的配置参数变的不再合适。比如，如果终端设备处于波束覆盖的边缘或者上行载波覆盖的边缘时，波束或者上行载波的参考信号接收功率可能会存在波动，这就导致了终端设备在根据随机接入的配置参数选择波束，或者上行载波或者带宽部分时，会在不同波束，或者不同的上行载波，或者不同的带宽部分之间频繁的进行随机接入尝试。
有鉴于此，本申请提供了一种的随机接入配置参数的优化方法，终端设备对随机接入信道的性能进行测量记录，并将该测量记录报告发送给无线接入网设备，使得无线接入网设备可以根据终端设备的测量记录报告的内容，比如基于波束或者上行载波等进行及时准确地优化随机接入配置参数，从而提高系统的接入成功率，减少随机接入过程的时延，降低随机接 入尝试次数，降低竞争接入的冲突概率，以及提高终端设备在随机接入过程中的用户体验。
第一方面，本申请提供了一种通信方法，该方法可以包括：第一无线接入网设备接收来自于终端设备的第一信息，该第一信息可以包括：该终端设备进行随机接入所使用的波束的标识以及该终端设备在该波束的随机接入信息，该第一无线接入网设备基于该第一信息的内容进行随机接入信道的优化。通过本设计，示例性的有益效果包括：可以使得无线接入网设备针对不同的波束进行及时准确的随机接入信道的优化，提高系统的接入成功率，减少随机接入过程的时延，降低随机接入尝试次数，降低竞争接入的冲突概率，从而提高终端设备在随机接入过程中的用户体验。
