Description

网络接入配置方法、网络接入方法、通信设备及存储介质
本申请基于申请号为201610395362.4、申请日为2016年06月06日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本发明涉及无线通信领域的接入技术，尤其涉及一种网络接入配置方法、网络接入方法、通信设备及存储介质。
背景技术
移动互联网以及机器类型到机器类型(Machine to Machine，M2M)用户设备的盛行引发大量的移动数据应用，极大的改变了数据包的传输特点。例如，M2M用户设备的通信引发大量的突发小数据包业务；进而导致在通信网络中出现了大量的通信小数据包，并且即时通信以及更多的“永远在线”业务产生了大量保活小数据包。然而，现有移动网络的基础是基于“面向网络连接”的方式来实现通信的；尽管这种“面向连接”的服务方式能够很好解决传统的更偏电路域的流状(Streaming)业务的高效传输，例如视频业务、文件共享、话音等等，这种通信方式难以适配新兴的小数据包业务传递，造成大量的传输开销。
这里的小数据包通常是指数据包长度很小的数据包，且这些数据包的信令比性能很低。这里的数据信令比，是有效数据同信令的比值。这里的信令包含网络信令：无线资源连接(Radio Resource Connection，RRC)层的连接建立信令、切换信令、网络MAC层的资源请求信令，以及底层的测量反馈信令等。对于即时消息(Instant Massage，IM)业务，由于经常伴随心跳保活信息的传输以支持永远在线(Always on)用户体验，其信令开销 还包括心跳保活消息以及对应引发的网络信令开销)。显然地，如果延续既有的蜂窝传输协议框架，大量涌现的短突发业务势必给移动网络传输带来巨大的信令负担。
现有流业务有一个明显的会话开始和中断：当会话中断之后，也就代表了一个会话的结束，业务不存在明显拖尾；用户设备在会话中断后也就很自然地进入休眠态。而对于一个突发型业务，会话的开始和中断则要模糊很多，会话中的数据包相对没那么连续，导致很难区分清楚一个用户设备数据包之间的间隔是发生在一个会话之内，还是一个会话之外。并且了解到网络会根据数据包之间间隔时间长短来考虑是否需要先释放一个连接、实现用户设备的节电，当会话和数据包模糊化之后，移动用户设备面向网络的连接释放从一个会话一次，到一个数据包一次，而一次连接完成的数据量从一个会话的数据量变成为一个数据包的数据量。此外，在长期演进系统(Long Term Evolution，LTE)系统中，一次连接释放包含安全激活、专用信令以及数据承载的建立，涉及10余次信令交互、能够产生约为256字节的信令负荷。考虑到即时通信小数据包的短突发特征，传输单位数据的信令开销显然增大了。而用户设备长期在休眠和激活两个状态来回变换，也很难实现有效的休眠节电。
第三代合作伙伴项目(the 3rd Generation Partnership Project，3GPP)的通信协议版本12(简称R12)、增强的机器类通信(enhance Machine Type Communication，eMTC)的通信协议以及通信协议版本13(简称R13)，均有面向利用机器类通信(Machine Type Communication，MTC)小数据服务提供优化的解决方案。主要MTC的弱移动性、业务单一性，弱化移动支持信令以及承载的沟通信令。通过默认承载以及由网络附属存储(Network Attach Storage，NAS)信令携带完成小数据包的传输。该方案是在考虑高层协议上尽可能适配既有LTE协议框架提出来的，从本质上讲，目前MTC 解决方案考虑的是有调度的方案。但是，经研究发现，在特定的业务和网络场景下，调度方案不一定是最有效的。
发明内容
有鉴于此，本发明实施例期望提供一种网络接入配置方法、网络接入方法、通信设备及存储介质，以解决同一调度方案导致的无线资源的有效利用低的问题。

具体实施方式
以下结合说明书附图及具体实施例对本发明的技术方案做进一步的详细阐述，应当理解，以下所说明的优选实施例仅用于说明和解释本发明，并不用于限定本发明。
实施例一：
如图1所示，本实施例提供一种网络接入配置方法，包括：
步骤S110：获取网络状况信息；
步骤S120：根据所述网络状况信息，配置网络接入策略及对应的接入资源，形成网络接入策略及接入资源配置信息；
步骤S130：将所述接入资源配置信息和所述网络接入策略，发送给用户设备。
本实施例所述的网络接入配置方法，可为应用于基站中的方法。本实施例所述的网络接入配置方法，还可为运用于各种无线网络中的网络接入配置方法。
在步骤S110中，基站会获取网络状况信息，这的网络状况信息可用于表征当前网络的闲忙状况的信息，也可以为表征当前网络可用资源数量与接入需求之间的比值关系等。
在本实施例的步骤S110中基站可以按照预定时间间隔，获取所述网络状况信息，例如周期性的获取所述网络状况信息；具体如，周期性的读取网络负载，或网络负载率等信息。
在步骤S120中，基站可以根据所述网络状况信息，确定出与当前的网络状况条件相适应的接入资源配置及网络接入策略。这样基站就能够完成 无线资源的配置，以及根据网络接入策略控制用户设备(User Equipment，UE)的接入。所述接入资源配置信息可为对基站对接入资源配置结果对应的接入资源配置信息。所述网络接入策略可包括在不同网络状况下对应制定的各种接入方案。这里的接入方案可包括接入方式及接入格式参数等各种限制UE接入的参数。
在步骤S130中会将步骤S120中确定得到的接入资源配置信息和网络接入策略发送给UE，由UE根据从基站接收的接入资源配置信息和网络接入策略进行网络接入，也可以仅将所述网络状况信息发送给UE，这样UE接收到所述网络状况信息之后，通过查询预先存储在UE中的网络状况信息与接入资源配置信息和网络接入策略的对应关系，确定出适用于当前网络状况的网络接入配置和网络接入策略，再根据查询确定的网络接入配置和网络接入策略，进行网络接入。
在本实施例中所述网络接入策略可以用网络接入策略映射表来表示，表1为所述网络接入策略映射表的一个示例：
业务类型和数据包长度 网络接入方式
业务类型1和数据包长度1 接入方式一
业务类型2和数据包长度2 接入方式二
业务类型2和数据包长度3 接入方式三
表1
在本实施例中所述接入资源配置可包括对随机接入序列的配置，包括对上行传输资源的配置。例如，将一个或多个时频资源分配给对应的业务类型进行数据传输。UE根据所述接入资源配置信息，及自身需要发送给的业务类型，可以确定采用哪些在哪些时频资源上进行数据传输。例如，基站根据当前的网络状况信息，确定出频段A用于传输超高可靠性低时延通信(Ultra-Reliable and Low Latency Communication，URLLC)，并形成对应 的接入资源配置信息；UE在接收到该接入资源配置信息时，在自己需要发送URLLC业务时，就采用频带A来上传数据。
总之，本实施例提供了一种动态的根据当前的网络状况信息，确定接入资源配置及网络接入策略的方法，这样能够确定出最适合当前网络状况的网络接入方式，以更有效的利用无线资源，提升数据传输的效率。
所述网络状况信息包括网络负载状况信息。在本实施例中所述网络负载状况信息可包括网络负载值或网络负载率。在本实施例中所述网络负载值可为一个小区或一个基站当前的负载；所述网络负载率可理解为网络负载值与小区或基站的最大负载的比值。
所述网络接入策略包括接入方案及所述接入方案的采用条件。所述接入方案包括：接入方式；其中，所述接入方式用于指示用户设备采用以何种方式接入。
所述接入方案包括接入方式；
所述接入方式包括：免调度传输方式、短突发接入方式、脉冲调度接入方式及退避接入方式的至少其中之一；
其中，免调度传输方式为：基站在不为用户设备调度专属资源时，用户设备直接抢占资源进行数据传输的接入方式；
所述短突发接入方式为：基站在不为用户设备调度资源时，用户设备抢占资源进行接入原因和/或数据包长度指示和/或用户设备标识和/或缓存状态报告等数据包信息传输的接入方式；
所述脉冲调度接入方式为：基站为用户设备调度专属资源的接入方式；
所述退避接入方式为：发生接入冲突时进行退避，并在退避后默认选择所述脉冲调度接入的接入方式。
接入方式可分为两大类，分别为第一类接入方式和第二类接入方式；其中，第一类接入方式和第二类接入方式的都可包括上述任意一种接入方 式。例如，第一类接入方式和第二类接入方式都可包括免调度传输方式等。第一类接入方式和第二类接入方式的不同点在于，用户设备在接入基站之前，采用第一类接入方式需要先发送同步信号与基站进行同步；而采用第二类接入方式接入时，无需先发送同步信号进行同步。例如，当用户设备A采用第一类接入方式中的免调度传输进行接入时，先向基站发送同步信号，然后再利用所述免调度传输方式进行接入和数据传输。若用户设备A采用第二类接入方式中的免调度传输进行接入时，直接利用所述免调度传输方式进行接入和数据传输。
所述接入方案还包括接入格式参数；
所述接入格式参数至少能够用于指示接入时需要携带的信息；所述接入时需要携带的信息包括：接入原因、传输的数据包长度、用户设备标识及缓存状态报告信息的至少其中之一。此外，所述接入格式参数还包括：信息的调制编码方式及信息占用资源数量的至少其中之一。
在本实施例中接入方式与接入格式参数之间可以没有固定的对应关系，不同的接入方式可以对应于相同的接入格式进行接入。例如，脉冲调度接入方式和退避接入方式都可以发送以同样的调制编码方式形成的数据包。
当然不同的接入方式与资源配置信息也相同，即不同的接入方式可以共用同样的通信资源进行通信。
在本实施例中所述接入方式可包括短突发接入方式、脉冲调度接入方式或退避接入方式等。这里的所述脉冲调度接入方式为：基站为用户设备调度专属资源的接入方式。所述短突发接入方式可包括和携带接入原因和/或数据包长度指示的接入方式。这里的免调度传输方式，则UE无需基站为不专门为该UE参与资源调度或不专门向该UE发送调度信息的情况下，直接抢占通信资源进行数据传输。
以下提供结合上述网络接入策略映射表，提供几个能够表征接入方案与采用条件的对应关系表。
表2为当前负载率低于A％时，确定的网络接入策略；
表3为当前负载率低于B％时，确定的网络接入策略；
表4为当前负载率低于C％时，确定的网络接入策略；
表5为当前负载率高于C％时，确定的网络接入策略。
所述A的取值可为10，15或25等取值；所述B的取值可为50、60或55等取值；所述C的取值可为70或75等取值；总之，上述A、B及C的取值都尽是一个示例，不局限于上述值，在具体实现时，还可以根据需要调整上述值进行调整。结合表2至表4的内容，上述A、B及C的取值，满足A小于B，且B小于C。

表4
表2和表3中的免调度数据传输为基站在不为UE调度专属资源，UE直接抢占无线资源进行数据传输。
表2至表4中的脉冲调度接入是指：脉冲调度接入可包括基站为用户设备调度专属资源的接入方式。
表4中的退避接入可以包括随机退避接入，这里的随机退避为UE随即退避一个时间长度之后，再次进行随机接入。
表2至表4中A1、B1及C1的取值，可以为任意值，在本实施例中所述A1可为30，所述B1和C1的取值可为10。但是A1、B1及C1的取值不局限于上述取值，通常所述A1大于所述B1。
在本实施例中所述非低时延URLLC和低时延的URLLC代表两种不同 业务类型的URLLC，所述低时延URLLC的业务的时延要求高于非低时延的URLLC的时延要求。一个URLLC业务是否为低时延的URLLC或非低时延的URLLC，可以将该URLLC业务的时延要求与预设的时延阈值比较来划分。
通过表2可知，在网络负载率较低时，对于数据包长度较小时，数据包可以采用免调度传输。若网络负载率较低时，对于数据包长度加大的数据包可以允许采用短突发接入，一方面可以满足小数据包的数据包个数多，传输需求次数大，传输时延块的特点，针对于数据包长度较大的数据包，允许采用短突发接入，可以满足数据传输效率高的特点。
通过表3和表4可知，低时延的业务类型优先选用能够时延性低的接入方式进行接入；而非低时延的业务类型可以选用时延较大一些的接入方式进行接入。这样避免部分业务类型，不区分不同业务类型的时延性，采用统一接入方式，接入冲突及接入的效率低的现象。
作为本实施例的进一步改进，所述步骤S120可包括：
所述接入格式参数还包括：信息的调制编码方式及信息占用资源数量的至少其中之一。
在本实施例中同时所述接入格式参数还会限定信息的数据长度、调制编码方式及信息占用资源数量等信息格式，UE接收到上述信息格式之后，根据上述信息格式进行上行数据的传输。例如，将上行数据分割成上述数据长度，利用上述调制编码方式对上行数据进行编码等。这里的数据长度可为数据量的多少。这样的话，基站在接收到UE发送按照上述信息发送的上行数据之后，能够快速的进行信息的解调和解码，提升基站的信息解码和解调效率，降低基站因解调和解码消耗的系统资源。
基站在向UE发送数据时，可以采用广播、多播或单播中的任意一种，在本实施例中所述步骤S130可选为：利用广播消息或多播消息或随机接入 响应消息，向用户设备发送所述接入资源配置信息和所述网络接入策略。
在本实施例中可以利用随机接入响应来发送上述接入资源配置信息和网络接入策略。当然在具体实现时，基站还可以利用无线资源控制(Radio Resource Controller，RRC)信息等用户专属信息来发送步骤S130中需要发送的信息。总之在具体实现过程中，基站向UE发送数据的方式有多种，不局限于上述任意一种。在具体的实现过程中，还可以采用广播、多播和单播任意两种结合的方式进行。
例如，若一个信息需要发送给小区内所有的UE，则优选采用广播，若一个信息需要发送给UE组，则可以采用组播，若仅需发送个别的UE，则可以采用单播。
在本实施例中，若步骤S130中发送的网络状况信息，则优选为采用广播消息来发送。为了减少基站的信息发送量，可以将某一个业务类型的网络接入策略和资源接入资源配置信息，采用组播的发送给有该业务类型的UE。故在具体实现时，可以结合广播、组播和单播中任意两种方式进行信息的发送。
作为本实施例的进一步改进，所述步骤S120可包括：
将网络负载与预设负载阈值进行比较，根据比较结果选择接入方式。
例如，所述将网络负载与预设负载阈值进行比较，根据比较结果选择接入方式，包括：若所述网络负载大于所述预设负载阈值，则确定允许所述用户设备采用脉冲调度接入方式接入网络。再例如，所述将网络负载与预设负载阈值进行比较，根据比较结果选择接入方式，还包括：若所述网络负载小于所述预设负载阈值，则确定允许所述用户设备采用数据包长度不大于第一长度阈值的数据包以免调度传输，或者确定允许所述用户采用短突发接入方式接入网络；其中，所述短突发接入方式包括用户设备抢占资源进行接入原因和/或数据包长度指示和/或用户设备标识和/或缓存状态 报告等数据包信息传输的接入方式。
以下结合上述实施例，给出一个具体的示例，假设所述预设负载阈值包括多个，分别为以下的第一负载阈值至第四负载阈值。
所述步骤S120可包括：
若网络负载大于第一负载阈值，则确定采用发生接入冲突时进行退避并在退避之后默认选择脉冲调度接入方式进行接入；其中，所述脉冲调度接入方式为：基站为用户设备调度专属资源的接入方式。
可选地，若所述网络负载大于第二负载阈值且小于所述第一负载阈值，则确定允许所述用户设备采用脉冲调度接入方式接入网络；其中，所述脉冲调度接入方式为：基站为用户设备调度专属资源的接入方式。
可选地，若所述网络负载大于第三负载阈值且小于所述第二负载阈值，则确定允许所述用户设备采用数据包长度不大于第一长度阈值的数据包以短突发接入方式接入网络；其中，所述短突发接入方式包括携带接入原因和/或数据包长度指示的接入方式。
此外，若所述网络负载大于第四负载阈值且小于所述第三负载阈值，则确定允许所述用户设备采用数据包长度不大于第二长度阈值的数据包以短突发接入方式接入网络。
在上述实施例中，所述第一负载阈值大于所述第二负载阈值；所述第二负载阈值大于所述第三负载阈值，所述第三负载阈值大于所述第四负载阈值；
所述第一长度阈值小于所述第二长度阈值。
在本实施例中所述网络负载可为负载值或负载率。在本实施例中具体提供一个如何确定网络接入策略的方案，具有实现简单的特点。
总之，本实施例所述的网络接入配置方法，会根据网络状况信息，来确定网络当前的网络资源配置及网络接入策略，以提高网络接入效率，更 有效的利用网络资源。
值得注意的是：上述方法的执行流程不局限于图1所示的流程，若基站向UE发送网络状况信息，则基站可以在执行完步骤S110后向UE发送所述网络状况信息，即所述步骤S120和步骤S130可以没有一定的先后顺序。
实施例二：
如图2所示，本实施例提供一种网络接入方法，包括：
步骤S210：获取用户特征信息和业务特征信息；
步骤S220：接收基站发送的信息；其中，所述基站发送的信息包括接入资源配置信息和所述网络接入策略；
步骤S230：根据所述用户特征信息、所述业务特征信息及基站发送的信息，进行网络接入。
本实施例所述网络接入方法可为应用于UE中的方法。
在步骤S210中所述用户特征信息可包括用户设备的特征信息，例如，用户设备的类型；不同的用户设备有不同的通信能力，最适合的接入方式也不同。所述业务特征信息，不同的业务有不同的业务特点，有些业务对应的数据量大，上下文关联性很大；而有些业务确很零散，需要由多个小数据包来发送。
在步骤S220中接收基站发送的信息，基站发送的信息可包括网络状况信息，还可能是接入资源配置信息和网络接入策略。值得注意的是，本实施例中所述步骤S210和步骤S220没有一定的先后顺序，两个步骤可以同时执行，也可以步骤S210位于步骤S220之前，也可以是步骤S220在步骤S210之前执行，仅需确保步骤S210和步骤S220都在步骤S230之前即可。
故在步骤S220中UE可能直接收到基站根据网络状况信息确定的接入资源配置信息和网络接入策略。UE还可能接收的网络状况信息，再查询存 储在UE内部的网络状况信息与接入资源配置信息和网络接入策略的对应关系，确定出与当前的网络状况信息相对应的接入资源配置信息和网络接入策略。
在步骤S230中，将根据所述接入资源配置信息和网络接入策略，进行网络接入，这样就可以很好的控制UE的接入，一方面能够更好的利用无线资源，提升资源的有效利用率；同时还能够通过资源的更好利用，提升数据传输效率。
在本实施例中，步骤S230中，UE根据自身当前需要发送的数据的业务特征信息，查询所述接入资源配置信息和所述网络接入策略，确定出接入方案；基于该接入方案进行网络接入。在本实施例中所述业务特征信息可包括数据的业务类型、数据的时延容忍特性，数据包长度等信息。所述时延容忍特性可以表明该数据是低时延业务类型，还是非低时延业务类型。
在步骤S230中可以将用户特征信息和业务特征信息，与从基站接收的信息进行匹配，选择出最合适的接入方案。
例如，根据业务特征信息，发现UE目前需要传输多个数据量较小的数据包，此时，根据基站接收的信息，确定出免调度传输方式适合数据量较小的数据包直接传输，则在步骤S230中通过这种匹配，将选择免调度传输方式进行接入。当然以上仅是一个示例，不能解释为对步骤S230的全部限定。
例如，UE根据当前的网络状况信息，查询所述接入策略，确定出请求接入的业务类型对应的接入方案；根据当前的网络状况信息，确定出请求传输的数据包长度对应的接入方案；根据当前的网络状况信息，确定出请求接入的业务类型及数据包长度对应的接入方案。
值得注意的是本实施例中所述接入资源配置信息、网络接入策略及网络状况信息的详细内容和对应关系都可以参照实施例一，在此就不重复了。
总之，本实施例所述的UE会根据基站根据当前的网络状况信息码，确定的接入资源配置信息和网络接入策略，这样以更有效率的利用无线资源，同时提升数据传输的整体效率。

总之，本实施例提供的UE，在进行网络接入时，具有能够采用适宜于当前的网络状况的接入方式或接入方案来接入，从而能够达到更好的利用无线资源和更有效率的进行数据传输。
以下结合上述任意实施例提供几个具体示例：
示例一：
网络侧的设备，例如基站，能够根据网络不同的网络状态，动态地为用户设备配置不同的接入资源以及/或者网络接入策略，并能够将这些信息传递给用户；用户设备进一步根据自身的不同数据发送需求，差异化选用网络提供的接入资源以及/或者接入策略。这只不同的接入资源即为进行接入资源配置。
第一步：根据网络状况信息，比如网络负载，调整接入资源配置以及网络接入策略。所述网络接入策略可包括如前述实施例提供的网络接入策 略映射表。并将接入资源配置的接入资源配置信息和网络接入策略信息，分别或者一起发送给用户设备，比如通过广播、多播或者单播发送给用户设备。
第二步：UE收到网络接入策略，基于网络接入策略，在对应接入资源执行差异化的网络接入操作。可选地，不同业务类型可以执行不同的接入方式。不同的业务类型可能对应不同的数据包长度，也可以对应着不同的时延要求。比如，国际电信联盟(International Telecommunication Union，ITU)定义的第五代合作伙伴项目5G三大场景：增强的移动宽带、低功耗大连接(mMTC)以及低时延高可靠(URLLC)，可能涉及到本案提出的不同的接入方式。再比如，业务是首次接入，还是接入失败后重新接入，首次接入和非首次接入可能需要携带的信息内容不同，或者首次接入和重新接入采用的接入方式不同。上述接入方式可包括免调度传输方式、短突发接入方式、脉冲调度接入方式及退避接入方式等等。短突发接入可能携带用户标识信息、用户设备的缓冲状态包括(Buffer Status Report，BSR)及用户数据等；脉冲调度接入方式类似传统LTE的接入方式，由基站进行同步的数据调度传输。可选地，不同的网卡接入策略还可包括指示用户设备上传的信息格式，方便网络端解调。所述信息格式可能包括信息的位数、信息的调制编码方式、信息占用资源数目等等。
基站在向UE发送数据时，可以采用广播资源信息。一般地，广播资源消息发送可以通过公共系统消息来发送。可选地，无线资源的使用方式包括脉冲调度接入、携带比如数据块尺寸等信息的短突发接入，以及直接携带数据的免调度传输。该广播消息显性或者隐性地携带接入的判定方式，显性的方式，比如通过专用几个比特指示具体的接入方式；隐性的方式，可以通过系统默认约定，执行对应的网络接入操作。此外，基站同时显性广播了脉冲调度接入和短突发接入资源，用户设备基于接入信息或者数据 包长度，是否满足一定条件，判定具体选择何种资源进行接入。比如，当用户数据包长度小于既定的阈值Pthresh，则可以选择采用突发接入的方式进行接入或者传输。Pthresh可以是网络和用户设备预定义的数据包长度的门限值，或者由网络通过广播或者单播传递给用户的信息。Pthresh可能是一个值或者是对应不同接入指示的一组值。
当然基站向用户设备发送接入资源配置信息或网络接入策略，还可以采用多播方式。多播资源消息发送至少适配如下例子。用户设备接入之后、冲突解决之前的多播资源分配，在长期演进(Long Term Evolution，LTE)就是随机接入响应消息msg2；面向一组用户的资源池预调度。
前述退避参数、网络负载、数据包长度可以是预接入资源配置信息、广播信息、Msg2传递信息，或者通过用户专属信令(比如RRC信息等)传递的信息，也可以是用户通过不同的方式，可以获得的信息，比如网络负载是一个广播信息，但是数据包长度、退避参数可能是通过用户专属信令配置。图中，L1>L2>L3>L4，P1<P2.注意：不同场景，比如eMBB，mMTC以及URLLC采用的具体参数可能会有区别，比如对于低时延URLLC，退避参数会设置更小，或者取消，以保证数据的快速传输；当然，也可以采用相同的参数，通过资源调控的方式，分割不同场景使用的资源，并始终保持低时延URLLC场景拥有更充裕的资源，更低的负载率。
示例二：
如图5所示，本示例提供一种随机接入方法，包括：
步骤S1：基站广播网络接入策略；这里的网络接入策略是根据当前的网络状况信息确定的。
步骤S2：用户设备基于网络接入策略，判定接入方式，并执行网络接入操作。
示例三：
如图6所示，本示例提供一种随机接入方法，包括：
步骤S11：基站多播的接入资源配置信息；这里的接入资源配置信息是根据表征当前网络状况的网络状信息确定的。
步骤S12：用户设备判断接入方式，并在所述接入资源配置信息对应的接入资源上进行接入退避或进行数据传输。
示例四：
如图7所示，本示例提供一种网络接入方法，包括：
步骤S31：用户设备发送随机接入请求Msg1，通常所述Msg1中可包括导频。
步骤S32：接收随机接入响应消息Msg2；所述Msg2可携有网络接入策略或网络负载状态信息等；所述网络接入策略可包括退避参数及接纳的数据包长度。这里接纳的数据包长度可为基站将接收的数据包长度。
步骤S33：用户设备基于预配置或广播消息或者Msg2，决策接入方式。
所述步骤S33可包括：
步骤S331：若网络负载>L1，执行动作选项1：根据退避参数随机退避；
步骤S332：若网络负载>L2，执行动作选项2：发送脉冲调度接入请求；即进行脉冲调度接入；
步骤S333：若网络负载>L3，执行动作选项3：采用短突发接入，并携带用户设备标识、接入原因或BSR等信息，信息长度不大于P1(字节)；
步骤S334：若网络负载>L4，执行动作选项4：采用免调度接入，发送的数据包长度不大于P2。
步骤S34：接收后续资源调度的调度信息，或数据传输确认信息。
所述上述实施例中，终端先导频同步，而后选择对应的接入方式；当网络接入策略是多播或者广播时，终端也可以先接听接入策略，再综合选择是否同步以及选择什么样的接入策略。
