技术领域
本公开涉及通信技术领域，特别涉及一种接入方法、网络设备及移动通信终端。
背景技术
在相关的移动通信系统中，TDD(Time Division Duplexing，时分双工)技术的上下行频段的频率范围相同，且频率带宽相等；FDD(Frequency Division Duplexing，频分双工)技术的上下行频段的频率带宽相等，频率范围不同，上下行配对使用。因此，在相关技术中一个小区的上下行频段的频率范围都是对应出现的，且频率带宽都是相同的。在长期演进LTE-Advanced技术中，其引入了载波聚合，通过上行或者下行载波聚合，可以配置上下行载波的带宽不同，但是载波聚合应用于小区间聚合时，每个参与载波聚合的小区仍然需要上下行频率对应且带宽相同，不支持上下行频率范围不对应且带宽不同的传输方式。
第五代移动通信技术(5th-Generation，简称5G)系统中，新频谱以高频和毫米波为主。然而，频段的频率越高，其抗摔落性越差，导致其覆盖性能越差，由上可知，5G的覆盖性能较差。随着大规模天线和波束赋形技术的应用，网络设备的下行频段的覆盖范围得到了一定增强，但针对移动通信终端的上行频段的覆盖范围较弱的问题，由于相关技术中不支持一个小区内上下行频率范围不对应且带宽不同的传输方式，因此，尚未提出有效的解决方案，且随着下行增强技术的应用，上下行频段的覆盖范围之间的差异越来越大。

具体实施方式
下面将结合本公开中的附图，对本公开中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
本公开提供了一种接入方法，网络设备发送一个下行频率范围和至少两个上行频率范围的频率信息和物理随机接入信道参数，移动通信终端接收网络设备发送的一个下行频率范围和至少两个上行频率范围的频率信息和物理随机接入信道参数；在所述至少两个上行频率范围中的一个目标上行频率范围上，利用目标物理随机接入信道参数发起随机接入。通过在现有频段的基础上增加至少一个低频段的上行频率范围，将低频段的上行频率范围和高频段的上行频率范围配对使用，可以利用低频段的上行覆盖范围对高频段上行覆盖范围的不足进行补偿，从而增强移动通信终端的上行覆盖范围，进而减小上下行频谱的覆盖范围之间的差异，提高系统的整体性能。
在此，应该说明的是，本公开具体实施例中的至少两个上行频率范围和相关技术的多个子载波等不同，本公开具体实施例中的至少两个上行频率范围对应于上下行非对称传输技术，而相关技术中的上行载波或者是上行频段都是与下行频段成对出现。
参见图1，图1表示本公开提供的接入方法的流程图，本实施例的接入方法用于网络设备，所述网络设备支持在一个下行频率范围和至少两个上行频率范围上工作，如图1所示，包括以下步骤101。
步骤101、发送一个下行频率范围和至少两个上行频率范围的频率信息和物理随机接入信道参数。
本公开中，以网络设备可以通过小区的广播消息向移动通信终端发送信息和/或参数进行举例说明，但本公开不因此限制网络设备向移动通信终端发送信息和/或参数的方式。另外，该步骤中的所述至少两个上行频率范围中的任一上行频率范围分别对应一个频段。
也就是说，本公开的接入方法用于网络设备，所述网络设备支持在一个下行频率范围和至少两个上行频率范围上工作，所述接入方法包括：发送频率指示信息和物理随机接入信道参数，所述频率指示信息包括一个下行频率范围和至少两个上行频率范围的频率信息。
所述物理随机接入信道参数用于终端从至少两个上行频率范围中选择接入上行频率范围，所述物理随机接入信道参数包括用于终端接入的上行频率范围的中心频点。
本公开的网络设备可以是基站。
在长期演进(Long Term Evolution，简称LTE)系统中，网络设备的任一小区的上行传输方向和下行传输方向，分别只支持一个频率范围，且上行传输方向支持的频率范围和下行传输方向支持的频率范围对应出现。为方便理解，参见图2，如图2所示，上行传输方向仅支持频率范围为U，下行传输方向仅支持频率范围为D，且频率范围U和频率范围D对应出现，其中，频率范围U的中心频率可以为3.5GHz，频率范围D的中心频率可以为3.5GHz，但不仅限于此。因此，小区仅广播其支持的频段编号，且该频段编号仅携带一个上行频率范围和一个下行频率范围。
但在本公开中，网络设备支持在一个下行频率范围和至少两个上行频率范围上工作。考虑到频段的频率与频段的覆盖性能成反比，即频段的频率越高，则频段的覆盖性能越弱，因此，可以理解的，所述至少两个上行频率范围中的至少一个上行频率范围的频段低于5G系统中的上行频率范围的频段，从而可以利用低频段的上行覆盖范围对高频段上行覆盖范围的不足进行补偿，从而增强移动通信终端的上行频段的覆盖范围，进而减小上下行频段的覆盖范围之间的差异，提高系统的整体性能。为方便理解，请参见图3，如图3所示，上行传输方向支持两个频率范围，分别为频率范围U1和频率范围U2，下行传输方向仅支持频率范围D，从而实现上下行非对称传输，其中，频率范围U1的中心频率可以为3.5GHz，频率范围U2的中心频率可以为900MHz，频率范围D的中心频率可以为3.5GHz，但不仅限于此，需要说明的是，图3中的上行频率范围的个数仅为示意，并不因此限制上行方向支持的上行频率范围个数，本公开具体实施例的方案可以应用于两个或两个以上的上行频率 范围。因此，本实施例的小区的广播消息中携带有所述至少两个上行频带范围和一个下行频带范围的频率信息。
具体地，小区可以在FBI(Frequency band indicator，频率波段指示器)中广播一个新的频段编号，该新频段编号携带有所述至少两个上行频带范围和一个下行频带范围，例如：下行频率范围的中心频率为3.5GHz，上行频率范围的中心频率分别为3.5GHz和900MHz。
小区也可以在FBI中广播一个传统频段编号，同时广播其支持的纯上行(Supplemental Uplink，简称SUL)频率范围，其中，该传统频段编号携带一个上行频率范围和一个下行频率范围。例如：该传统频段编号携带的上行频率范围的中心频率为3.5GHz，下行频率范围的中心频率为3.5GHz，在Multi Band Info List(多波段信息列表)中广播其支持的中心频率为900MHz的SUL频率范围。
小区也可以在FBI中广播一个传统频段编号，同时广播其支持的纯上行(Supplemental Uplink，简称SUL)频率范围，其中，该传统频段编号仅携带一个下行频率范围。例如：该传统频段编号携带的下行频率范围的中心频率为3.5GHz，在multi Band Info List(多波段信息列表)中广播其支持的中心频率为900MHz和中心频率为3.5GHz的SUL频率范围。
当然，小区也可以通过其他方式将所述至少两个上行频带范围和一个下行频带范围的频率信息携带在广播信息中，如通过广播信息中的保留字段，在此不做限定。
在本实施例中，小区的广播消息中还包括物理随机接入信道参数，以使移动通信终端利用该物理随机接入信道参数向网络设备发起随机接入。其中，物理随机接入信道参数可以是多组随机接入资源，但不仅限于此。针对多组随机接入资源，其每一组随机接入资源对应不同的上行频率范围，例如：中心频率为900MHz和3.5GHz的上行频率范围分别分配了不同的随机接入资源。
本公开中，网络设备可以与移动通信终端建立通信，且网络设备和移动通信终端均支持在一个下行频率范围和至少两个上行频率范围上工作。其中，网络设备可以是eLTE网络设备，也可以是5G网络设备，但不仅限于此。移动通信终端可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑 (Laptop Computer)、个人数字助理(personal digital assistant，简称PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等终端侧设备，但不仅限于此。
本公开提供的接入方法，网络设备发送一个下行频率范围和所述至少两个上行频率范围的频率信息和物理随机接入信道参数，以使移动通信终端接收到一个下行频率范围和所述至少两个上行频率范围的频率信息和物理随机接入信道参数后，可以在所述至少两个上行频率范围中的一个目标上行频率范围上，利用目标物理随机接入信道参数发起随机接入。通过在现有频段的基础上增加至少一个低频段的上行频率范围，将低频段的上行频率范围和高频段的上行频率范围配对使用，可以利用低频段的上行覆盖范围对高频段上行覆盖范围的不足进行补偿，从而增强移动通信终端的上行频段的覆盖范围，进而减小上下行频段的覆盖范围之间的差异，提高系统的整体性能。
可选的，所述接入方法还包括：发送选择参数、第一优先级参数、第二优先级参数和接入概率参数中的至少一个；所述选择参数用于移动通信终端从所述至少两个上行频率范围中确定接入上行频率范围，或从接收到的所述物理随机接入信道参数中选择接入物理随机接入信道参数；所述第一优先级参数用于指示所述至少两个上行频率范围对应的优先级；所述第二优先级参数用于指示所述物理随机接入信道参数对应的优先级；并且所述接入概率参数用于指示所述至少两个上行频率范围对应的接入概率。
在本公开中，同一个小区对应了至少两个上行频率范围，而至于终端如何确定目标上行频率范围和目标物理随机接入信道参数，则可以通过多种方式实现。
在一种方式下，可以由网络侧进一步发送其他的参数来控制终端确定目标上行频率范围和目标物理随机接入信道参数，对此进一步说明如下。
本公开具体实施例中，该方法还可以包括：发送选择参数、第一优先级参数、第二优先级参数和接入概率参数中的至少一个；所述选择参数用于移动通信终端从所述至少两个上行频率范围中确定接入上行频率范围，或从接收到的所述物理随机接入信道参数中选择接入物理随机接入信道参数；所述第一优先级参数用于指示所述至少两个上行频率范围对应的优先级；所述第 二优先级参数用于指示所述物理随机接入信道参数对应的优先级；所述接入概率参数用于指示所述至少两个上行频率范围对应的接入概率。
当通过广播消息发送时，即：小区的广播消息中进一步携带选择参数、第一优先级参数、第二优先级参数和接入概率参数中的至少一个，以使移动通信终端在接收到网络设备发送的上述参数后，基于上述至少一个参数，从所述至少两个上行频率范围中选择一个上行频率范围，并在该上行频率范围上向网络设备发起随机接入，从而提高移动通信终端随机接入成功的几率。
该步骤中，所述选择参数可以为频率范围选择参数，用于移动通信终端从所述至少两个上行频率范围中选择接入上行频率范围，即移动通信终端可以在该接入上行频率范围上发起随机接入；所述选择参数也可以是物理随机接入信道选择参数，用于移动通信终端从接收到的所述物理随机接入信道参数中选择接入物理随机接入信道参数，以使移动通信终端在基于该接入物理随机接入信道参数对应的上行频率范围上，发起随机接入，从而提高移动通信终端随机接入成功的几率。
可选的，所述选择参数为最低下行信号门限。具体地，所述选择参数为允许移动通信终端接入某上行频率范围的最低下行信号门限，以使移动通信终端基于测量到的下行信号质量，和接收到的各上行频率范围的最低下行信号门限，判断其所处的上行频率范围的覆盖范围。具体地，若移动通信终端测量到的下行信号质量大于某上行频率范围的最低下行信号门限，则可以说明移动通信终端在该上行频率范围的覆盖范围之内，移动通信终端可通过该上行频率范围接入。其中，最低下行信号门限可以是小区的RSRP(Reference Signal Receiving Power，参考信号接收功率)、RSRQ(Reference Signal Receiving Quality，参考信号接收质量)、SINR(Signal to Interference plus Noise Ratio，信号与干扰加噪声比)中的一种或者多种。这样，移动通信终端可以在其可以接入的上行频率范围中的一目标上行频率范围上，向网络设备发起随机接入，从而可以提高移动通信终端随机接入成功的几率。
进一步地，所述至少两个上行频率范围中，除覆盖范围最大的频率范围之外，每一个频率范围具有各自对应的允许接入的最低下行信号门限，覆盖范围越小的频率范围对应的最低下行信号门限越高。为方便理解，请参见图 4，如图4所示，该上行传输方向支持三个上行频率范围，分别为上行频率范围U1、上行频率范围U2和上行频率范围U3，其中，上行频率范围U1的覆盖范围最小，上行频率范围U2的覆盖范围次之，上行频率范围U3的覆盖范围最大。最低下行信号门限T1为允许移动通信终端通过上行频率范围U1接入的最低下行信号门限，最低下行信号门限T2为允许移动通信终端通过上行频率范围U2接入的最低下行信号门限，由上可知，最低下行信号门限为T1大于最低下行信号门限为T2。
若测量到的下行信号值高于最低下行信号门限T1，即测量到的下行信号值与最低下行信号门限T1的差值大于0，由最低下行信号门限为T1大于最低下行信号门限为T2可得测量到的下行信号值高于最低下行信号门限为T2，即测量到的下行信号值与最低下行信号门限T2的差值大于0，则表示移动通信终端可接入上行频率范围U1、上行频率范围U2和上行频率范围U3，其处在上行频率范围U1、上行频率范围U2和上行频率范围U3的覆盖范围内。
若测量到的下行信号值低于最低下行信号门限T1但高于最低下行信号门限T2，则表示移动通信终端可接入上行频率范围U2和上行频率范围U3，其处在上行频率范围U2和上行频率范围U3的覆盖范围内。
若测量到的下行信号值低于最低下行信号门限T2，则表示移动通信终端可接入上行频率范围U3，其处在上行频率范围U3的覆盖范围内。
该步骤中，所述第一优先级参数用于指示所述至少两个上行频率范围对应的优先级。进一步地，一种方式中，上行频率范围的中心频率越大，该上行频率范围的优先级越高。例如：中心频率为3.5GHz的上行频率范围的优先级较高，中心频率为900MHz的上行频率范围的优先级较低。这样，移动终端在接收到至少两个上行频率范围的频率信息后，可以根据每个上行频率范围的优先级，优先从所述至少两个上行频率范围中选择优先级别较高的上行频率范围，并在该上行频率范围上，向网络设备发起随机接入，从而提高移动通信终端随机接入成功的几率。
该步骤中，所述第二优先级参数用于指示所述物理随机接入信道参数对应的优先级。进一步地，一种方式中，上行频率范围的中心频率越大，该上行频率范围对应的物理随机接入信道参数的优先级越高。例如：中心频率为 3.5GHz的物理随机接入信道参数的优先级较高，中心频率为900MHz的物理随机接入信道参数的优先级较低。这样，移动终端在接收到至少两个上行频率范围的频率信息后，可以根据每个上行频率范围对应的物理随机接入信道参数的优先级，优先从所述至少两个上行频率范围中选择接入物理随机接入信道参数的优先级别较高的上行频率范围，并在该上行频率范围上，向网络设备发起随机接入，从而提高移动通信终端随机接入成功的几率。
该步骤中，所述接入概率参数用于指示所述至少两个上行频率范围对应的允许移动通信终端接入网络设备的概率，以使移动通信终端基于检测到的接入随机数，和各个上行频率范围对应的接入概率进行比较，判断移动通信终端向网络设备发起随机接入的接入上行频率范围，在接入上行频率范围中选择一目标上行频率范围，向网络设备发起随机接入，从而提高移动通信终端随机接入成功的几率，其中，上行频率范围接入随机数介于0和1之间。
具体地，若检测到的接入随机数小于某上行频率范围对应的接入概率,则移动通信终端可以在该上行频率范围上发起随机接入；反之则继续用相同的方法判断是否可以在其他上行频率范围上发起随机接入。进一步地，所述接入概率参数可以是所述至少两个上行频率范围中的每个上行频率范围对应一个接入概率P，进一步地，也可以是每个上行频率范围的不同类型对应一个接入概率P，上行频率范围的不同类型和接入概率P的映射关系如表1所示。
表1：上行频率范围的不同类型和接入概率P的映射关系表
  业务类型一 业务类型二 业务类型三
上行频率范围U1 P1-1 P1-2 P1-3
上行频率范围U2 P2-1 P2-2 P2-3
可选的，该方法还包括：发送频率范围指定参数；所述频率范围指定参数用于指定所述至少两个上行频率范围中的至少一个频率范围。
在本公开中，同一个小区对应了至少两个上行频率范围，因此，该步骤中，小区的广播消息中进一步携带频率范围指定参数，以使移动通信终端在接收到网络设备发送的频率范围指定参数后，基于频率范围指定参数在所述至少两个上行频率范围中指定的至少一个上行频率范围中，选择一个目标上行频率范围作为接入上行频率范围，并在该目标上行频率范围上向网络设备 发起随机接入，从而提高移动通信终端随机接入成功的几率。例如：小区广播允许移动通信终端在中心频率为900MHz的上行频率范围上发起随机接入，即频率范围指定参数指定的上行频率范围的中心频率为900MHz，则移动通信终端仅可以在中心频率为900MHz的上行频率范围上发起随机接入，不可以在其他上行频率范围上，如中心频率为3.5GHz的上行频率范围上发起随机接入，由于中心频率为900MHz的上行频率范围为网络设备指定的上行频率范围，因此，在该上行频率范围上发起随机接入时，由于该目标上行频率范围为网络设备指定的上行频率范围之一，因此网络设备在接收到随机接入响应之后即可随机接入成功，从而可以提高随机接入成功的几率。
本公开还提供一种接入方法，该接入方法用于移动通信终端。图5表示本公开提供的接入方法的另一流程图，如图5所示，该接入方法包括以下步骤501-502。
步骤501、接收网络设备发送的一个下行频率范围和至少两个上行频率范围的频率信息和物理随机接入信道参数。
需要说明的是，本实施例作为上述实施例对应的移动通信终端的实施方式，该实施例中关于“网络设备发送的所述至少两个上行频率范围的频率信息和物理随机接入信道参数”的描述可参见上述实施例的相关说明，为了避免重复说明，在此不再赘述。
步骤502、在所述至少两个上行频率范围中的一个目标上行频率范围上，利用目标物理随机接入信道参数发起随机接入。
该步骤中，移动通信终端可以随机在所述至少两个上行频率范围中选择一个上行频率范围作为目标上行频率范围，并利用该目标上行频率范围对应的目标物理随机接入信道参数发起随机接入；当然，移动通信终端也可以基于预设的规则在所述至少两个上行频率范围中选择一个上行频率范围作为目标上行频率范围，并利用该目标上行频率范围对应的目标物理随机接入信道参数发起随机接入，在此不作限定。
本实施例的接入方法，接收网络设备发送的一个下行频率范围和所述至少两个上行频率范围的频率信息和物理随机接入信道参数；在所述至少两个上行频率范围中的一个目标上行频率范围上，利用目标物理随机接入信道参 数发起随机接入。通过在现有频段的基础上增加至少一个低频段的上行频率范围，将低频段的上行频率范围和高频段的上行频率范围配对使用，可以利用低频段的上行覆盖范围对高频段上行覆盖范围的不足进行补偿，从而增强移动通信终端的上行频段的覆盖范围，进而减小上下行频段的覆盖范围之间的差异，提高系统的整体性能。
可选的，该方法还包括：接收所述网络设备发送的选择参数、第一优先级参数、第二优先级参数和接入概率参数中的至少一个；所述选择参数用于移动通信终端从所述至少两个上行频率范围中选择接入上行频率范围，或从接收到的所述物理随机接入信道参数中选择接入物理随机接入信道参数；所述第一优先级参数用于指示所述至少两个上行频率范围对应的优先级；所述第二优先级参数用于指示物理随机接入信道参数对应的优先级；所述接入概率参数用于指示所述至少两个上行频率范围对应的接入概率。
需要说明的是，本实施例作为上述实施例对应的移动通信终端的实施方式，该实施例中关于“网络设备发送的选择参数、第一优先级参数、第二优先级参数和接入概率参数中的至少一个”以及各参数的描述可参见上述实施例的相关说明，为了避免重复说明，在此不再赘述。
可选的，所述在所述至少两个上行频率范围中的一个目标上行频率范围上，利用目标物理随机接入信道参数发起随机接入具体包括：依据接收到的选择参数从所述至少两个上行频率范围中确定所述接入上行频率范围；从所述接入上行频率范围中确定目标上行频率范围，并确定目标物理随机接入信道参数；以及在所述目标上行频率范围上，利用所述目标随机接入信道参数发起随机接入。
该步骤中，移动通信终端依据接收到的选择参数，和其自身测量到的信号值进行比较，从所述至少两个上行频率范围中确定所述接入上行频率范围，其中，所述选择参数可以为最低下行信号门限，对应地，信号值可以为下行信号值。为方便理解，本步骤结合图4进行举例说明，如图4所示，该上行传输方向支持三个上行频率范围，分别为上行频率范围U1、上行频率范围U2和上行频率范围U3，其中，上行频率范围U1的覆盖范围最小，上行频率范围U2的覆盖范围次之，上行频率范围U3的覆盖范围最大。最低下行信号 门限T1为允许移动通信终端通过上行频率范围U1接入的最低下行信号门限，最低下行信号门限T2为允许移动通信终端通过上行频率范围U2接入的最低下行信号门限，其中，最低下行信号门限为T1大于最低下行信号门限为T2。若测量到的下行信号值低于最低下行信号门限T1但高于最低下行信号门限T2，则表示移动通信终端处在上行频率范围U2和上行频率范围U3的覆盖范围内，即接入上行频率范围为上行频率范围U2和上行频率范围U3。
该步骤中，在移动通信终端选择接入上行频率范围，或从接收到的所述物理随机接入信道参数中选择接入物理随机接入信道参数后，可以随机在接入上行频率范围中选择一个上行频率范围作为目标上行频率范围，并利用该目标上行频率范围对应的目标物理随机接入信道参数发起随机接入；当然，移动通信终端也可以基于预设的规则在接入上行频率范围中选择一个上行频率范围作为目标上行频率范围，并利用该目标上行频率范围对应的目标物理随机接入信道参数发起随机接入，在此不作限定。例如：移动通信终端根据其所处的上行覆盖范围区域在固定上行频率发起接入，如图4所示，同时处于上行频率范围U1、上行频率范围U2和上行频率范围U3的覆盖范围内的移动通信终端在上行频率范围U1上发起随机接入，同时处于上行频率范围U2和上行频率范围U3的覆盖范围内的移动通信终端在上行频率范围U2上发起随机接入，仅处于上行频率范围U3的覆盖范围内的移动通信终端在上行频率范围U3上发起随机接入。
可选的，从所述接入上行频率范围中确定目标上行频率范围具体包括：从所述接入上行频率范围中随机选择一个上行频率范围作为目标上行频率范围。
该步骤中，若接入上行频率范围为上行频率范围U2和上行频率范围U3，则移动通信终端既可以选择上行频率范围U2作为目标上行频率范围，也可以选择上行频率范围U3作为目标上行频率范围，在此不作限定。
可选的，从所述接入上行频率范围中确定目标上行频率范围，并确定目标物理随机接入信道参数具体包括：依据接收到的所述第一优先级参数、第二优先级参数和接入概率参数中的至少一个确定目标上行频率范围和/或目标物理随机接入信道参数。
该步骤中，在选择接入上行频率范围，或从接收到的所述物理随机接入信道参数中选择接入物理随机接入信道参数后，移动通信终端可进一步依据接收到的所述第一优先级参数、第二优先级参数和接入概率参数中的至少一个确定目标上行频率范围和/或目标物理随机接入信道参数。
具体地，在选择接入上行频率范围，或从接收到的所述物理随机接入信道参数中选择接入物理随机接入信道参数后，移动通信终端可进一步依据接收到的所述第一优先级参数确定目标上行频率范围，进而确定目标上行频率范围对应的物理随机接入信道参数作为目标物理随机接入信道参数。例如：若选择接入上行频率范围，或从接收到的所述物理随机接入信道参数中选择接入物理随机接入信道参数为上行频率范围U2和上行频率范围U3，则可依据指示上行频率范围U2和上行频率范围U3对应的优先级确定目标上行频率范围，由上述实施例可知，上行频率范围的中心频率越大，该上行频率范围的优先级越高，因此，若上行频率范围U2的中心频率大于上行频率范围U3的中心频率，则表示上行频率范围U2的优先级较高，从而可选择上行频率范围U2作为目标上行频率范围。
具体地，在选择接入上行频率范围，或从接收到的所述物理随机接入信道参数中选择接入物理随机接入信道参数后，移动通信终端可进一步依据接收到的所述第二优先级参数确定目标物理随机接入信道参数，进而确定目标物理随机接入信道参数对应的上行频率范围作为目标上行频率范围。例如：若选择接入上行频率范围，或从接收到的所述物理随机接入信道参数中选择接入物理随机接入信道参数为上行频率范围U2和上行频率范围U3，则可依据指示上行频率范围U2的物理随机接入信道参数和上行频率范围U3的物理随机接入信道参数对应的优先级确定目标上行频率范围，由上述实施例可知，上行频率范围的中心频率越大，该上行频率范围的物理随机接入信道参数的优先级越高，因此，若上行频率范围U2的中心频率小于上行频率范围U3的中心频率，则表示上行频率范围U3的物理随机接入信道参数对应的优先级较高，从而可选择上行频率范围U3的物理随机接入信道参数作为目标物理随机接入信道参数。
具体地，在选择接入上行频率范围，或从接收到的所述物理随机接入信 道参数中选择接入物理随机接入信道参数后，移动通信终端可进一步依据接收到的所述接入概率参数确定目标上行频率范围，进而确定目标上行频率范围对应的物理随机接入信道参数作为目标物理随机接入信道参数。例如：若选择接入上行频率范围，或从接收到的所述物理随机接入信道参数中选择接入物理随机接入信道参数为上行频率范围U2和上行频率范围U3，则可依据指示所述至少两个上行频率范围对应的允许移动通信终端接入网络设备的概率确定目标上行频率范围，由上述实施例可知，若检测到的接入随机数小于某上行频率范围对应的接入概率,则移动通信终端可以在该上行频率范围上发起随机接入；反之则继续用相同的方法判断是否可以在其他上行频率范围上发起随机接入。因此，若上行频率范围U2的接入概率为0.5，移动终端检测到的接入随机数为0.4，则表示移动通信终端可以在上行频率范围U2上发起随机接入。
进一步地，若符合接入概率要求的上行频率范围有多个，移动通信终端你可以随机选择一个上行频率范围发起随机接入，或者结合所述第一优先级参数、第二优先级参数，选择一个上行频率范围发起随机接入，在此不作限定。
可以理解的，在选择接入上行频率范围，或从接收到的所述物理随机接入信道参数中选择接入物理随机接入信道参数后，移动通信终端可进一步依据所述第一优先级参数、第二优先级参数和接入概率参数中的任意两个的组合，或者所有三个参数的组合，从所述接入上行频率范围中确定目标上行频率范围，并确定目标物理随机接入信道参数。
可选的，所述选择参数为最低下行信号门限，所述至少两个上行频率范围中，除覆盖范围最大的频率范围之外，每一个频率范围具有各自对应的允许接入的最低下行信号门限，覆盖范围越小的频率范围对应的最低下行信号门限越高；所述接入上行频率范围对应的最低下行信号门限；或对应的最低下行信号门限与一补偿值的和值小于下行信号测量值。
需要说明的是，本实施例作为上述实施例对应的移动通信终端的实施方式，该实施例中关于“所述选择参数”的描述可参见上述实施例的相关说明，为了避免重复说明，在此不再赘述。
该步骤中，考虑不同的移动通信终端的类型，例如不同功率等级的，不同发射功率等级的移动通信终端检测到的上行覆盖范围不同。因此终端在确定接入上行频率范围时，需要引入一个补偿值，以表征不同接入上行频率范围类型所对应的上行增益。具体地，若移动通信终端测量到的下行信号质量大于某上行频率范围的最低下行信号门限与移动通信终端补偿值的和值，则可以说明移动通信终端可接入该上行频率范围，移动通信终端在该上行频率范围的覆盖范围之内即该上行频率范围为接入上行频率范围。其中，补偿值可以为网络设备允许的移动通信终端最大发射功率，但不仅限于此。
可选的，该方法还包括：接收网络设备发送的频率范围指定参数，用于指定所述至少两个上行频率范围中的至少一个上行频率范围；所述目标上行频率范围为所述至少一个上行频率范围中的一个。
需要说明的是，本实施例作为上述实施例对应的移动通信终端的实施方式，该实施例中关于“频率范围指定参数”的描述可参见上述实施例的相关说明，为了避免重复说明，在此不再赘述。
该步骤中，移动通信终端基于频率范围指定参数，选择接入上行频率范围，或从接收到的所述物理随机接入信道参数中选择接入物理随机接入信道参数，若接入上行频率范围的个数大于1，则可在接入上行频率范围随机选择一个上行频率范围作为目标上行频率范围，或者进一步依据选择参数、第一优先级参数、第二优先级参数和接入概率参数中的至少一个从接入上行频率范围随机选择一个上行频率范围作为目标上行频率范围。可选的，所述至少一个频率范围为所述至少两个上行频率范围中覆盖范围最大的上行频率范围。但不仅限于此。这样，移动通信终端在该目标上行频率范围上发起随机接入时，由于该目标上行频率范围为网络设备指定的上行频率范围之一，因此网络设备在接收到随机接入响应之后即可随机接入成功，从而可以提高随机接入成功的几率。
本公开还提供一种网络设备，网络设备支持在一个下行频率范围和至少两个上行频率范围上工作。图6表示本公开提供的网络设备的示意图，如图6所示，网络设备600包括发送器601，用于发送所述至少两个上行频率范围的频率信息和物理随机接入信道参数。

可选的，所述选择参数为最低下行信号门限。
可选的，所述至少两个上行频率范围中，除覆盖范围最大的频率范围之外，每一个频率范围具有各自对应的允许接入的最低下行信号门限，覆盖范围越小的频率范围对应的最低下行信号门限越高。

本公开还提供一种移动通信终端，移动通信终端支持在一个下行频率范围和至少两个上行频率范围上工作。图7表示本公开提供的移动通信终端的示意图，如图7所示，移动通信终端700包括接收器701和处理器702。
其中，接收器701，用于接收网络设备发送的所述至少两个上行频率范围的频率信息和物理随机接入信道参数；处理器702，用于在所述至少两个 上行频率范围中的一个目标上行频率范围上，利用目标物理随机接入信道参数发起随机接入。
可选的，接收器701，还用于接收所述网络设备发送的选择参数、第一优先级参数、第二优先级参数和接入概率参数中的至少一个；所述选择参数用于移动通信终端从所述至少两个上行频率范围中选择接入上行频率范围，或从接收到的所述物理随机接入信道参数中选择接入物理随机接入信道参数；所述第一优先级参数用于指示所述至少两个上行频率范围对应的优先级；所述第二优先级参数用于指示物理随机接入信道参数对应的优先级；所述接入概率参数用于指示所述至少两个上行频率范围对应的接入概率。
可选的，处理器702用于所述至少两个上行频率范围中的一个目标上行频率范围上，利用目标物理随机接入信道参数发起随机接入时，具体用于：依据接收到的选择参数从所述至少两个上行频率范围中确定所述接入上行频率范围；从所述接入上行频率范围中确定所述目标上行频率范围，并确定所述目标物理随机接入信道参数；在所述目标上行频率范围上，利用所述目标随机接入信道参数发起随机接入。
