具体实施方式
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，对于处于非激活态或空闲态的用户设备(UE)，用户设备需要向核心网发送数据时，或者核心网需要向用户设备发送数据或信令时，用户设备需要先完成随机接入过程。随机接入过程包括基于竞争的随机接入和基于非竞争的随机接入。对于基于竞争的随机接入，用户设备有一定的几率接入失败，导致连接建立时延。
为解决上述问题，本实施例中基站在收到核心网向非激活态的用户设备发送的消息时，基站通过寻呼信令向用户设备发送前导码(preamble)，用户设备可根据该前导码进行基于非竞争的随机接入，提高随机接入的成功率，以便用户设备接收该消息。
图1是根据一示例性实施例示出的一种传输前导码的方法的流程图，该传输前导码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101-103。
在步骤101中，接收核心网发送的消息，所述消息指向非激活态的用户设备。
在步骤102中，生成寻呼信令，所述寻呼信令包括为所述用户设备分配的前导码。
在步骤103中，发送所述寻呼信令。
本实施例中，用户设备的状态包括空闲态、非激活态和激活态。对于非激活态的用户设备，其在移动过程中不会与核心网保持实时同步。因此，接收核心网发送的消息的基站，是核心网根据本地保存的用户设备的上下文，确定的最后一个服务该用户设备的基站。
所述消息可以是通知消息，通知基站发送寻呼信令。通知消息和寻呼信令均包括所述用户设备的标识。或者，所述消息是核心网要向用户设备发送的消息，在一个实施例中，所述消息包括用于传输数据的消息，和/或，用于传输信令的消息。
基站收到该消息后，先不向用户设备发送该消息，因为基站不知道该用户设备是否在自己的覆盖区域内，所以本实施例中基站先向用户设备发送寻呼信令，所述寻呼信令包括为所述用户设备分配的前导码，可触发用户设备进行基于非竞争的随机接入。待用户设备接入小区后，即用户设备处于激活态后，向用户设备发送所述消息。
本实施例中基站可以通过寻呼方式向用户设备发送前导码，使用户设备进行基于非竞争的随机接入，提高了随机接入的成功率，有助于用户设备更及时的与网络侧通信。
在一个实施例中，所述方法还包括下列之一：步骤A1、步骤A2和步骤A3。
在步骤A1中，接收核心网发送的前导码。
本实施例中核心网可以在所述消息中携带前导码，该前导码用于该消息所指向的用户设备。或者，核心网向基站发送一个或多个前导码。当基站需要生成寻呼信令时，从中选择一个前导码。核心网可以在发送所述消息之前向基站发送前导码，也可以在发送所述消息之后发送前导码。如果是在发送所述消息之后发送前导码，那么基站在接收到前导码之后才能生成寻呼信令。
在步骤A2中，为所述用户设备分配前导码。
本实施例中基站可以为所述消息所指向的用户设备分配前导码。
在步骤A3中，接收运行、管理和维护设备(Operations,Administration and Maintenance，OAM)发送的前导码。
本实施例中，OAM可以预先向基站发送一个或多个前导码。当基站需要生成寻呼信令时，从中选择一个前导码。
在一个实施例中，所述步骤103包括：步骤B1和/或步骤B2。
在步骤B1中，向覆盖范围内的用户设备发送所述寻呼信令。
在步骤B2中，通过基站间接口向其它基站发送所述寻呼信令。
本实施例中，基站会向覆盖范围内的用户设备发送所述寻呼信令。但是，处于非激活态的用户设备，可能移动到其它位置，超出该基站的覆盖范围，因此，为了使寻呼信令可以更好的到达用户设备，基站还可以向其它基站发送所述寻呼信令。基站间传输寻呼信令可以通过基站间接口(如Xn接口)。所述基站与所述其它基站属于同一RNA(RAN Notification Area， 无线通知区域)。收到寻呼信令的其它基站可以继续向自身覆盖范围内的用户设备发送所述寻呼信令，以及通过基站间接口向其它基站发送所述寻呼信令。相当于本实施例可以在RNA内发送寻呼信令。便于用户设备及时收到寻呼信令。
基站还可以向其它基站发送所述消息，以便用户设备随机接入成功后，其它基站(也就是当前服务该用户设备的基站)可以向用户设备发送所述消息。
下面通过实施例详细介绍实现过程。
图2是根据一示例性实施例示出的一种传输前导码的方法的流程图，该传输前导码的方法用于基站等接入网设备。如图2所示，该方法包括以下步骤201-205。
在步骤201中，接收核心网发送的消息，所述消息指向非激活态的用户设备。
在步骤202中，为所述用户设备分配前导码。
在步骤203中，生成寻呼信令，所述寻呼信令包括为所述用户设备分配的前导码。
在步骤204中，向覆盖范围内的用户设备发送所述寻呼信令。
在步骤205中，通过基站间接口向其它基站发送所述寻呼信令。
本实施例所述的基站是接收核心网发来的消息的基站，在其它场景下，该基站也可以作为其它基站，即接收寻呼信令的基站。下面针对该场景的实现过程进行介绍。
图3是根据一示例性实施例示出的一种传输前导码的方法的流程图，该传输前导码的方法用于基站等接入网设备。如图3所示，该方法包括以下步骤301-302。
在步骤301中，通过基站间接口接收其它基站发送的寻呼信令，所述寻呼信令包括前导码。
在步骤302中，发送所述寻呼信令。
本实施例中，基站在收到寻呼信令后，可立刻转发该寻呼信令，以便该寻呼信令更及时的到达用户设备。
在一个实施例中，所述步骤302包括：步骤C1和/或步骤C2。
在步骤C1中，向覆盖范围内的用户设备发送所述寻呼信令。
在步骤C2中，通过基站间接口向其它基站发送所述寻呼信令。
本实施例中，基站会向覆盖范围内的用户设备发送所述寻呼信令。但是，处于非激活态的用户设备，可能移动到其它位置，超出该基站的覆盖范围，因此，为了使寻呼信令可以更好的到达用户设备，基站还可以向其它基站发送所述寻呼信令。以便实现在RNA内发送寻呼信令。
以上介绍了基站侧的实现过程，相对的，用户设备侧也有相应的改进，下面针对用户设备侧的实现过程进行介绍。
图4是根据一示例性实施例示出的一种传输前导码的方法的流程图，该传输前导码的方法用于用户设备中，其中，用户设备可以是移动电话，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，接收基站发送的寻呼信令，所述寻呼信令包括前导码。
在步骤402中，向基站发送随机接入请求，所述随机接入请求包括所述前导码。
本实施例中，用户设备为处于非激活态的用户设备，可以接收和解析携带有前导码的寻呼信令。在该寻呼信令的触发下，进行基于非竞争的随机接入，在发送的随机接入请求消息中携带该前导码。提高了用户设备随机接入的成功率，以便用户设备更及时的接收后续的消息。
图5是根据一示例性实施例示出的一种传输前导码的方法的流程图，该传输前导码的方法用于核心网设备。如图5所示，该方法包括以下步骤501-502。
在步骤501中，向基站发送消息，所述消息指向非激活态的用户设备。
在步骤502中，向基站发送为所述用户设备分配的前导码。
本实施例中，核心网在需要向非激活态的用户设备发送消息时，向基站发送为所述用户设备分配的前导码。本实施例中的核心网有向基站发送前导码的功能。步骤501和步骤502可以通过一个消息实现，即所述消息携带前导码。也可以通过两个消息实现。并且执行顺序可以互换。
以上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。
