Description

一种终端接入基站的方法及装置
技术领域
本发明涉及通信技术领域, 特别涉及一种终端接入基站的方法及装置。 背景技术
目前, 数据信令分离网络由于能够有效提升网络容量、 降低网络信令开 销, 因此, 是未来无线网络演进的重要方向。 其中, 数据信令分离是指 CP ( Control Plane, 控制面)和 UP ( User Plane, 用户面)分离。 与传统的蜂窝 网络相比,数据信令分离网络的最大特点在于,将传统的 BS ( Base Station,基 站), 或者, eNB ( Evolved Node B )在物理上分割成两个部分: CBS ( Control
BS, 控制基站)和 DBS ( Data BS , 数据基站), 具体如图 1所示。
一般情况下, 终端在开机后不会有所在基站的信息, 因此, 终端在开机 后, 需要先接入基站, 进而实现终端与基站以及与其它终端间的通信。
现有技术中, 终端在数据信令分离网络中接入基站的主要过程如下: 步骤 a: DBS在资源块上周期性地发送同步信号 (PSS ( Primary
Synchronized Signal , 主同步信号 ) /SSS ( Secondary Synchronization Signal, 辅同步信号) ) ;
步骤 b: 终端 侦听同步信号读出 DBS所覆盖小区的 Cell lD ( Identity, 标 识) , 并根据读出的 Cell ID进行小区选择;
步骤 c: 终端与 DBS进行时间和频率同步后, 读取系统信息;
步骤 d: 终端按照读取的系统信息, 在选择的小区中向 CBS发起随机接 入, 然后, 建立与 CBS的 RRC ( Radio Resource Control, 无线资源控制 )连 接。
但是上述过程存在如下缺陷:
( 1 )此种方法不能应用于发送的同步信号中不包括 Cell ID的情况 在信令和数据分离的网络中, BS所覆盖小区可能没有独立的 Cell ID, 在 这种情况下, 上述终端接入基站的方法由于不能在侦听到的同步信号中读出 Cell ID, 就无法进行小区的选择, 因此, 也就无法接入基站, 进而无法实现 终端与基站以及与其它终端间的通信;
( 2 ) 资源浪费较严重、 接入过程复杂度较高
目前, 随着技术的发展, 小区数量在逐步提升, 小区密度也进一步提高, 此时, 终端从同步信号中读出的 DBS所覆盖小区的 Cell ID的数量较多, 终 端要对数量众多的 Cell ID进行运算才能选择出小区, 因此, 选择小区的复杂 度较高, 进而终端接入基站的复杂度也就较高, 同时, 由于要对数量众多的 Cell ID进行运算才能选择出小区, 需要消耗终端设备内部一定的处理资源, 因此, 资源浪费较严重。 发明内容

为使本发明实施例的目的、 技术方案和优点更加清楚, 下面将结合本发 明实施例中的附图, 对本发明实施例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发明一部分实施例, 而不是全部的实施例。 基于 本发明中的实施例, 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, 都属于本发明保护的范围。
本文中术语"和 /或", 仅仅是一种描述关联对象的关联关系, 表示可以存 在三种关系, 例如, A和 /或 B, 可以表示: 单独存在 A, 同时存在 A和 B, 单独存在 B这三种情况。 另外, 本文中字符" /,,, 一般表示前后关联对象是一 种"或"的关系。
下面结合附图对本发明优选的实施方式进行详细说明。
参阅图 2所示, 本发明实施例中, 终端接入基站的第一详细流程如下: 步骤 200: CBS接收终端发送的接入请求消息, 接入请求消息携带终端 的标识信息;
步骤 210: 根据接收到的终端的标识信息, 以及 DBS ID与终端的标识信 息的对应关系 , 确定接入终端的 DB S ID;
步骤 220: 接收 DBS ID对应的 DBS为终端分配的接入资源信息; 步骤 230: 发送接入资源信息至终端, 指示终端基于接入资源信息接入 DBS ID对应的 DBS。
本发明实施例中, 在步骤 220之前, 即在接收 DBS ID对应的 DBS为终 端分配的接入资源信息之前, 进一步包括如下操作:
将接入请求消息转发至 DBS ID对应的 DBS , 以请求 DBS为终端分配接 入资源。
本发明实施例中, CBS在确定接入终端的 DBS ID之前, CBS中要维护 DBS ID与终端的标识信息的对应关系, 该对应关系是 DBS接收终端发送的 探测信号, 并将探测信号中的终端标识信息上报给 CBS之后, CBS得到的, 在实现过程中, 可以为: 接收 DBS上报的携带终端的标识信息的探测信号, 以维护 DBS ID与终端的标识信息的对应关系。
例如: 终端 1与 CBS1完成时频同步后, 向 CBS1随机接入请求; CBS1 向终端 1 发送携带用于传输探测信号的资源信息的系统信息, 该系统信息中 携带资源块 5的系统信息, 则终端 1在资源块 5上每 5s发送携带终端 1的标 识信息的探测信号,与 CBS1相对应的 DBS1侦听到的携带终端 1的标识信息 的探测信号时, 将从侦听到的探测信号中解析出终端 1 的标识信息上报至 CBS1 ,进而 CBS1维护终端 1的标识信息与上 ^艮的 DBS1的 ID之间的对应关 系。
上述实施例只是讲述了与 CBS对应的一个 DBS上报终端的标识信息,在 实际应用中, 还可能有与 CBS对应的多个 DBS上报终端的标识信息。
例如: 终端 1与 CBS1完成时频同步后, 向 CBS1随机接入请求; CBS1 向终端 1 发送携带用于传输探测信号的资源信息的系统信息, 该系统信息中 携带资源块 5的系统信息, 则终端 1在资源块 5上每 5s发送携带终端 1的标 识信息的探测信号, 与 CBS1相对应的 DBS1、 DBS2侦听到的携带终端 1的 ID的探测信号时, 将从侦听到的探测信号中解析出终端 1的标识信息上报至 CBS1 , 进而 CBS1分别维护终端 1的标识信息与上 ^艮的 DBS1的 ID、 DBS2 的 ID之间的对应关系。
上述过程只是 CBS获取对应关系的两个实施例, 在实际应用中, 还有其 他多种实现方式, 在此不再进行——详述。
本发明实施例中, 终端获取发送探测信号的资源信息的方式有多种, 例 如, 终端可以与网络侧预先约定用于传输探测信号的资源信息, 此时, 终端 获取预先约定的资源信息的方式有多种, 例如, 终端先与 CBS完成时频同步 后, 向 CBS发送随机接入请求, 然后, 接收 CBS在接收到随机接入请求后, 返回的携带用于传输探测信号的资源信息的系统信息。
又例如, 确定预设的与终端的标识信息相对应的用于传输探测信号的资 源信息。
上述过程只是终端获取发送探测信号的资源信息其中的两个实施例, 在 实际应用中, 还有其他多种实现方式, 在此不再进行——详述。
本发明实施例中, 终端发送探测信号的方式有多种, 例如, 可以周期性 的发送, 或者, 可以在某一触发条件下发送, 在实际应用中, 有多种实现发 送的方式, 在此不再进行——详述。
本发明实施例中, 由于 DBS会周期性地或者多次上报从侦听到的探测信 号中解析出的终端的标识信息, 因此, CBS中维护的终端标识信息与 DBS的 ID的对应关系不是一成不变的, 会进行更新, 更新方式可以为: 对原有的终 端标识信息与 DBS的 ID的对应关系进行覆盖, 或者, 也可以为: 原有的终 端标识信息与 DBS的 ID的对应关系仍然保留, 再新增终端标识信息与 DBS 的 ID的对应关系。
例如, 在第一周期中, DBS1将从侦听到的探测信号中解析出的终端 1的 标识信息上 ^艮至 CBS1 , 则 CBS1将终端 1的标识信息与 DBS1的 ID的对应 关系进行维护,在第二周期中,若 DBS1和 DBS2均将从侦听到的探测信号中 解析出的终端 1的标识信息上 "^至 CBS1 , 则 CBS1将维护的终端 1的标识信 息与 DBS1的 ID的对应关系保留, 并新增终端 1的标识信息与 DBS2的 ID 的对应关系; 若仅 DBS2从侦听到的探测信号中解析出的终端 1 的标识信息 上报至 CBS1 , 则 CBS1将维护的终端 1的标识信息与 DBS1的 ID的对应关 系删除, 新增终端 1的标识信息与 DBS2的 ID的对应关系, 也就是说, 用终 端 1的标识信息与 DBS2的 ID的对应关系替代终端 1的标识信息与 DBS1的 ID的对应关系。
本发明实施例中, CBS接收上报终端的标识信息的 DBS可能不止一个, 此时, CBS将接收到的接入请求转发至上报终端标识信息的多个 DBS中的至 少一个 DBS即可, 然后,将接收到的上述至少一个 DBS的接入资源信息转发 至终端, 终端基于这些接入资源信息接入至少一个 DBS。
例如, 终端 1与 CBS1完成时频同步后, 向 CBS1随机接入请求; CBS1 向终端 1 发送携带用于传输探测信号的资源信息的系统信息, 该系统信息中 携带资源块 5的系统信息, 则终端 1在资源块 5上每 5s发送携带终端 1的标 识信息的探测信号, 与 CBS1相对应的 DBS1、 DBS2、 DBS3、 DBS4、 DBS5、 DBS6、 DBS7、 DBS8、 DBS9、 DBS10侦听到的携带终端 1 的标识信息的探 测信号时, 分别将从侦听到的探测信号中解析出终端 1 的标识信息上报至 CBS1 , 进而, CBS1分别维护终端 1的标识信息与 DBS1的 ID、 DBS2的 ID、 DBS3的 ID、 DBS4的 ID、 DBS5的 ID、 DBS6的 ID、 DBS7的 ID、 DBS8的 ID、 DBS9的 ID、 DBS10的 ID之间的对应关系 , 但是, CBS1将接入请求转 发至 DBS1的 ID对应的 DBS1、 DBS2的 ID对应的 DBS2、 DBS3的 ID对应 的 DBS3 , 并接收 DBS1、 DBS2、 DBS3分别返回的接入资源, 然后, CBS1 将 DBS1、 DBS2、 DBS3 分别对应的接入资源发送至终端, 以使得终端接入 DBS1、 DBS2、 DBS3。
本发明实施例中,由于 CBS从接入请求消息中确定出终端的标识信息后, 才艮据 DBS ID与终端的标识信息的对应关系,确定接入终端的 DBS ID, DBS ID 对应的 DBS为终端分配接入资源信息, 然后, 该终端根据接入资源信息接入 DBS即可, 因此, 即使 DBS所覆盖小区没有 Cell ID, 终端也能接入 DBS, 因此, 避免了终端在数据信令分离网络中接入基站时存在的无法接入的问题, 以及由于不存在对多个 Cell ID进行运算的过程, 因此, 解决了接入过程复杂 度较高, 及浪费终端处理资源的问题。
本发明实施例中, 终端的标识信息有多种形式, 例如, 终端的 ID, 还有 其他方式, 在此不再进行——详述。
参阅图 3所示, 本发明实施例中, 终端接入基站的第二详细流程如下: 步骤 300: DBS为终端分配接入资源信息, 其中, 接入资源信息是 DBS 在 CBS接收终端发送的接入请求消息, 根据接入请求消息携带终端的标识信 息, 以及 DBS ID与终端的标识信息的对应关系, 确定出 DBS ID后分配的; 步骤 310: 向 CBS发送接入资源信息, 以使得 CBS将接入资源信息发送 至终端, 指示终端基于接入资源信息接入 DBS。
本发明实施例中, 在 DBS为终端分配接入资源信息之前, 进一步包括: 接收 CBS转发的接入请求消息,接入请求消息用于请求 DBS为终端分配 接入资源。
本发明实施例中, 在接收 CBS转发的接入请求消息之前, 进一步包括: 接收终端发送的探测信号, 并将探测信号中的终端标识信息上报给 CBS, 以 使 CBS维护 DBS ID与终端的标识信息的对应关系。
例如: 终端 1与 CBS1完成时频同步后, 向 CBS1随机接入请求; CBS1 向终端 1 发送携带用于传输探测信号的资源信息的系统信息, 该系统信息中 携带资源块 5的系统信息, 则终端 1在资源块 5上每 5s发送携带终端 1的标 识信息的探测信号,与 CBS1相对应的 DBS1侦听到的携带终端 1的标识信息 的探测信号时, 将从侦听到的探测信号中解析出终端 1 的标识信息上报至 CBS1 ,进而 CBS1维护终端 1的标识信息与上 ^艮的 DBS1的 ID之间的对应关 系。
上述实施例只是讲述了与 CBS对应的一个 DBS上报终端的标识信息,在 实际应用中, 还可能有与 CBS对应的多个 DBS上"¾终端的标识信息, CBS 确定出与终端的标识信息对应的多个 DBS ID时, 对于任意一个 DBS ID对应 的 DBS, 接入终端时, 都可以执行步骤 300-步骤 310来实现终端的接入。
本发明实施例中, 终端获取发送探测信号的资源信息的方式有多种, 例 如, 终端可以与网络侧预先约定用于传输探测信号的资源信息, 此时, 终端 获取预先约定的资源信息的方式有多种, 例如, 终端先与 CBS完成时频同步 后, 向 CBS发送随机接入请求, 然后, 接收 CBS在接收到随机接入请求后, 返回的携带用于传输探测信号的资源信息的系统信息。
又例如, 确定预设的与终端的标识信息相对应的用于传输探测信号的资 源信息。
上述过程只是终端获取发送探测信号的资源信息其中的两个实施例, 在 实际应用中, 还有其他多种实现方式, 在此不再进行——详述。
本发明实施例中, 终端发送探测信号的方式有多种, 例如, 可以周期性 的发送, 或者, 可以在某一触发条件下发送, 在实际应用中, 有多种实现发 送的方式, 在此不再进行——详述。
在该实施例中, 由于 CBS从接入请求消息中确定出终端的标识信息后, 才艮据 DBS ID与终端的标识信息的对应关系,确定接入终端的 DBS ID, 然后, 该 DBS ID对应的 DBS为终端分配接入资源信息, 最后, 终端接收 CBS发送 的接入资源信息, 根据接入资源信息接入 DBS即可, 因此, 即使 DBS所覆盖 小区没有 Cell lD, 终端也能接入 DBS, 因此, 避免了终端在数据信令分离网 络中接入基站时存在的无法接入的问题, 以及由于不存在对多个 Cell ID进行 运算的过程, 因此, 解决了接入过程复杂度较高, 及浪费终端处理资源的问 题。
为了更好地理解本发明实施例, 以下给出具体应用场景, 针对终端接入 基站的过程, 做出进一步详细描述, 参阅图 4所示:
步骤 400:终端 1与 CBS1完成时频同步后,向 CBS1发送随机接入请求; 步骤 410: CBS1在接收到随机接入请求后, 向终端 1发送系统信息; 在该步骤中, 系统信息携带用于终端 1传输探测信号的资源信息。 步骤 420: 终端 1从接收到的系统信息中确定出资源信息, 并在确定的资 源信息对应的资源块上周期性的发送探测信号;
在该步骤中, 探测信号中携带终端 1的标识信息。
步骤 430: DBS1、 DBS2、 DBS3、 DBS4、 DBS5分别从用于传输探测信 号的资源上侦听到的携带终端 1 的标识信息的探测信号中读取出终端 1的标 识信息, 并分别将读取出的终端 1 的标识信息发送至 CBS1 ;
步骤 440: CBS1将终端 1 的标识信息分别与 DBS1、DBS2、DBS3、DBS4、 DBS5分别对应的 ID的对应关系,添加到已经维护的终端的标识信息与 DBS 的 ID的对应关系中;
步骤 450: 终端 1向 CBS1发送携带终端 1 的标识信息的接入请求消息, 接入请求中携带终端 1 的标识信息;
步骤 460: CBS1才艮据终端 1的标识信息、 终端的标识信息与 DBS的 ID 的对应关系 , 确定接入终端 1的 DBS1、 DBS2分别对应的 DBS ID;
步骤 470: CBS1接收 DBS1、DBS2返回的为终端 1分配的接入资源信息; 步骤 480: CBS1将接入资源信息发送至终端 1 , 以使得终端 1基于接入 资源信息接入 DBS1、 DBS2。
在该实施例中,由于 CBS1从接入请求消息中确定出终端 1的标识信息后, 才艮据 DBS ID与终端的标识信息的对应关系, 确定接入终端 1的 DBS 1 ID和 DBS2 ID,然后,该 DBS1 ID对应的 DBS1和 DBS2 ID对应的 DBS2为终端 1 分配接入资源信息, 最后, 终端接收 CBS1发送 DBS1和 DBS2为终端 1分配 的接入资源信息, 终端 1根据接入资源信息接入 DBS1、 DBS2即可, 因此, 即使 DBS1、 DBS2所覆盖小区没有 Cell ID, 终端 1也能接入 DBS1、 DBS2, 因此, 避免了终端在数据信令分离网络中接入基站时存在的无法接入的问题, 以及由于不存在对多个 Cell ID进行运算的过程, 因此, 解决了接入过程复杂 度较高, 及浪费终端处理资源的问题。

接收单元 10033 , 用于接收 CBS转发的接入请求消息, 接入请求消息用 于请求 DBS为终端分配接入资源。
综上所述, 本发明实施例中提供了一种终端接入基站的方法, 在提供的 这种方案中, CBS在接收到终端发送的接入请求消息后, CBS根据接收到的 终端的标识信息, 以及 DBS ID与终端的标识信息的对应关系, 确定接入终端 的 DBS ID, 然后, 与 DBS ID对应的 DBS为终端分配接入资源信息, 最后, 终端接入该 DBS即可, 因此, 即使 DBS所覆盖小区没有 Cell ID, 终端也能 接入 DBS, 避免了终端在数据信令分离网络中接入基站时存在的无法接入的 问题, 以及由于不存在对多个 Cell ID进行运算的过程, 因此, 解决了接入过 程复杂度较高, 及浪费终端处理资源的问题。
本发明是参照根据本发明实施例的方法、 设备(系统) 、 和计算机程序 产品的流程图和 /或方框图来描述的。 应理解可由计算机程序指令实现流程 图和 /或方框图中的每一流程和 /或方框、 以及流程图和 /或方框图中的流 程和 /或方框的结合。 可提供这些计算机程序指令到通用计算机、 专用计算 机、 嵌入式处理机或其他可编程数据处理设备的处理器以产生一个机器, 使 得通过计算机或其他可编程数据处理设备的处理器执行的指令产生用于实现 在流程图一个流程或多个流程和 /或方框图一个方框或多个方框中的功能的 装置。
这些计算机程序指令也可存储在能引导计算机或其他可编程数据处理设 备以特定方式工作的计算机可读存储器中, 使得存储在该计算机可读存储器 中的指令产生包括指令装置的制造品, 该指令装置实现在流程图一个流程或 多个流程和 /或方框图一个方框或多个方框中的功能。
这些计算机程序指令也可装载到计算机或其他可编程数据处理设备上, 使得在计算机或其他可编程设备上执行一系列操作步骤以产生计算机实现的 处理, 从而在计算机或其他可编程设备上执行的指令提供用于实现在流程图 一个流程或多个流程和 /或方框图一个方框或多个方框中的功能的步骤。
尽管已描述了本发明的优选实施例, 但本领域内的技术人员一旦得知了 基本创造性概念, 则可对这些实施例作出另外的变更和修改。 所以, 所附权 利要求意欲解释为包括优选实施例以及落入本发明范围的所有变更和修改。 脱离本发明实施例的精神和范围。 这样, 倘若本发明实施例的这些修改和变 型属于本发明权利要求及其等同技术的范围之内, 则本发明也意图包含这些 改动和变型在内。
