Description

为移动中继节点配置施主基站或施主小区的方法和设备 本申请要求于 2011 年 2 月 12 日提交中国专利局, 申请号为 201110036886.1 , 发明名称为 "为移动中继节点配置施主基站或施主 小区的方法和设备"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
本发明涉及通信技术领域,特别是涉及一种为移动中继节点配置 施主基站或施主小区的方法和设备。 背景技术
作为一种高性价比的网络覆盖扩展方式, Relay (中继 )技术被 引入到移动通信系统中。 为了改善在高速移动场景下, 移动通信服务 的质量, 引入了移动 Relay技术。 引入移动 Relay技术以后的无线通 信网络架构可以如图 1所示, 移动 RN ( Relay Node, 中继节点) 以 无线的方式连接到 DeNB ( Donor evolved Node B, 施主基站 )所管辖 的一个小区, 该小区被称为 RN的 Donor Cell (施主小区), 再经过有 线网络连接到核心网。移动 RN共有 2个无线接口:移动 RN与 DeNB 之间的接口为 Un接口, 归属移动 RN的用户终端 (R-UE )与移动 RN之间的接口为 Uu接口。 移动 RN在 Uu和 Un接口之间提供信号 接收、 解码、 协议转换和数据转发等处理功能。
移动 RN具有以下一些特征:
( 1 )移动 RN属于网络侧节点, 由运营商部署、 管理和维护。
( 2 )移动 RN可被安装于交通工具上, 为交通工具内部的用户 终端提供服务。 移动 RN与所服务的用户终端相对静止。
( 3 )在用户终端看来, 移动 RN就是一个普通基站。 移动 RN 管理独立的小区, 并拥有独立的物理层小区标识, 发送独立的同步信 号、 参考符号等。 归属到移动 RN的用户终端直接从移动 RN接收调 度和控制信令, 并直接向移动 RN发送上行控制和反馈信息。
( 4 )在 DeNB看来, 移动 RN类似一个用户终端。 移动 RN通 过 DeNB与核心网交互数据; 移动 RN需要对 Un口信号质量进行测 量,并根据测量结果在不同的 DeNB/Donor CelK即 DeNB或 /和 Donor Cell, 以下同)之间切换。
并不是所有的 eNB都适合作为移动 RN的 DeNB。 移动 RN的 DeNB和 Donor Cell是需要预先进行配置给移动 RN。 作为一个网络 侧节点,类似于位置固定的 RN (以下称固定 RN ),移动 RN的 Donor Cell由运营商经过 RN的 OAM ( Operation And Maintenance, 操作维 护) 系统进行配置。
固定 RN的开机流程可以分为两个阶段:
P介段一: RN开机后, 选择一个小区 (不必是支持 RN的小区), 采用与 UE( User Equipment,用户设备)相同的附着过程附着到网络, 然后从 OAM处获取初始配置参数, 例如, DeNB/Donor Cell列表等 参数, 并非所有的 eNB ( evolved Node B , 演进型基站) /Cell (小区) 都适合做 RN 的 DeNB/Donor Cell, 为了使 RN知道其可以接入的 DeNB/Donor Cell, 需要为 RN预配置 DeNB/Donor Cell。 在该配置完 成后, RN采用与 UE相同的去附着过程, 从网络去附着。 并触发阶 段二的操作。
P介段二: RN节点根据在阶段一中获得的 DeNB/Donor Cell列表, 选择一个合适的 DeNB/Donor Cell进行接入。 在完成一系列的准备工 作(例如, 建立 S1和 X2接口, 连接 OAM, 建立用户面承载等)后, RN开始为 UE提供服务。 在 RN开始正常工作以后, 除非出现关机 或异常情况(例如, RN重启动, 或 RN与 DeNB间接口的无线链路 出现严重问题 ) , RN将始终处于连接状态,而且 RN的位置不会改变, 也不会变更 DeNB/Donor CelL
在实现本发明的过程中, 发明人发现现有技术至少存在如下问 题:
现有技术以 RN是固定的为前提,所以, RN的 DeNB/Donor Cell 是始终不变的。 在引入了移动 RN以后, 移动 RN在移动的过程中, 经常会需要切换 DeNB/Donor Cdl, 而根据现有技术,无法为移动 RN 配置新的可接入的 DeNB/Donor Cdl。 发明内容

下面将结合本发明中的附图, 对本发明中的技术方案进行清楚、 完整的描述, 显然, 所描述的实施例是本发明的一部分实施例, 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 有做出创造性劳动的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。
实施例一
本实施例中, 移动 RN在移动过程中, 移动 RN的 OAM可获得 该移动 RN 的当前位置, 并可根据该移动 RN 的位置, 确定备选的 DeNB/Donor Cell列表并发送给该移动 RN的月良务 DeNB, 或通过该 移动 RN发送给该移动 RN的 良务 DeNB, 以供该移动 RN的 务 DeNB根据该移动 RN的备选 DeNB/Donor Cell列表为该移动 RN选 择目标 DeNB/Donor Cdl。
在上述过程中, 移动 RN侧的行为可包括:
移动 RN上报自己的位置, 例如上报当前 Donor Cell的 ID信息 或上报地理位置信息(如 GPS ( Global Positioning System, 全球定位 系统 )所测得的定位信息 )等;从 OAM侧接收 OAM根据该移动 RN 的位置所确定出的备选 DeNB/Donor Cell列表,将接收的 DeNB/Donor Cell列表通知当前的服务 DeNB; 以及, RN根据 DeNB配置的测量 参数进行测量和上报。
OAM侧的行为可包括: 根据移动 RN上报的位置信息, 查找该 移动 RN 周边的 DeNB/Donor Cell , 生成该移动 RN 的备选 DeNB/Donor Cell列表并发送给该移动 RN或该移动 RN的 DeNB。
移动 RN的月良务 DeNB侧的行为可包括:
为移动 RN 配置切换测量参数; 以及, 根据移动 RN 上报的 DeNB/Donor Cell列表为该移动 RN选择切换目标 DeNB/Donor Cdl。
参见图 2, 为本发明实施例提供的为移动 RN配置 DeNB/Donor Cell的流程示意图, 如图 2所示, 该流程可包括:
步骤 201 , 移动 RN的 OAM系统获取移动 RN的位置信息。 具体的, 移动 RN的位置信息可以是移动 RN自己直接上报给该 移动 RN的 OAM的,也可以是移动 RN的 DeNB上报给 eNB的 OAM, 然后由 eNB OAM通知移动 RN的 OAM的。 上述两种情况下的位置 上报过程可以是周期触发的 (上报周期间隔可配置), 也可以是事件 触发的。 如果是周期触发, 则移动 RN 可每隔一段时间, 向该移动
RN的 OAM上报一次自己的位置信息;或者,该移动 RN的服务 DeNB 每隔一段时间上报移动 RN的位置给 eNB OAM, 再由 eNB OAM通 知移动 RN的 OAM。 如果是事件触发的, 则移动 RN可以在切换时 上报自己的位置给移动 RN OAM; 或者, 在移动 RN切换时, 该移动 RN的目标 DeNB上4艮移动 RN的位置给 eNB OAM,再由 eNB OAM 通知移动 RN的 OAM。
其中, 移动 RN的位置信息可以是该移动 RN的地理位置信息, 该地理位置信息可以由移动 RN上的定位装置获得, 如 GPS装置, 也可以基于移动 RN 的定位算法得出, 还可以基于 RN 当前的服务 DeNB的定位算法得出; 移动 RN的位置信息也可以是移动 RN所属 的 DeNB/Donor Cell 的标识信息或频点信息等能够唯一标识该 DeNB/Donor Cell的信息; 移动 RN的位置信息还可以是上述信息的 组合。
步骤 202, 移动 RN的 OAM根据移动 RN的位置信息确定该移 动 RN可以接入的备选 DeNB/Donor Cdl。
RN 的 OAM 系统可先根据 RN 的地理位置或 RN 所属的 DeNB/Donor Cell确定符合一定条件 (例如, 与 RN所在位置相邻近) 的所有 eNB/Cdl , 由于并非所有的 eNB/Cdl 都适合做 RN 的 DeNB/Donor Cell , 因此再在这些 eNB/Cdl 中选择适合做 RN 的 DeNB/Donor Cell的 eNB/Cell, 最终选择出的 DeNB/Donor Cell即为 该移动 RN的备选 DeNB/Donor Cell。
步骤 203, 移动 RN的 OAM系统将备选 DeNB/Donor Cell通过 移动 RN指示给移动 RN的月良务 DeNB。
具体的,移动 RN可采用显式方式或隐式方式将备选 DeNB/Donor Cell指示给移动 RN的服务 DeNB。 所谓显式方式是指移动 RN的 OAM系统可以将备选 DeNB/Donor Cell的标识信息或频点信息发送 给该移动 RN 的服务 DeNB , 或者移动 RN 的 OAM 系统将备选 DeNB/Donor Cell的信息发送给该移动 RN的月良务 DeNB。 所谓隐式 方式可以是: 移动 RN的 OAM将备选 DeNB/Donor Cell信息发送给 移动 RN, 移动 RN在向其服务 DeNB上报小区测量结果时, 只上报 对备选 DeNB/Donor Cell的测量结果,从而使服务 DeNB可在上报测 量结果的 DeNB/Donor Cell 中选择移动 RN 的切换的目标 DeNB/Donor Cdl。 此后, 该移动 RN的 良务 DeNB就可以根据该移动 RN的备选 DeNB/Donor Cell为该移动 RN选择切换的目标 DeNB/Donor Cell了。 根据现有技术, 在 DeNB 为移动 RN选择切换目标时, 可参照移动 RN上报的小区测量结果进行选择。

在上述过程中, 移动 RN侧的行为可包括: 移动 RN根据 DeNB 配置的测量参数进行测量和上报测量结果。 可选的, 如果在 DeNB配 置的测量参数中, 包含备选的 DeNB/Donor Cell列表信息, 移动 RN 可以只对备选的 DeNB/Donor Cell列表所指示的备选目标小区进行测 量。 DeNB通知给移动 RN的信息可以是: 备选 DeNB/Donor Cell的 标识信息, 例如, DeNB ID或者 Donor Cell的小区 ID等, 也可以备 选 DeNB/Donor Cell的特征信息, 如小区频点信息等, 还可以是前述 两种信息的组合信息等。

参见图 3, 为本发明实施例提供的为移动 RN配置 DeNB/Donor Cell的流程示意图, 如图 3所示, 该流程可包括:
步骤 301 , eNB的 OAM系统获取移动 RN的位置信息。
具体的,移动 RN的位置信息可以是移动 RN的 DeNB上报给 eNB 的 OAM的。位置上报过程可以是周期触发的(上报周期间隔可配置 ), 也可以是事件触发的。 如果是周期触发, 则移动 RN的服务 DeNB每 隔一段时间上报移动 RN的位置给 eNB OAM。 如果是事件触发的, 则在移动 RN切换完成后, 移动 RN的目标 DeNB上报移动 RN的位 置给 eNB OAM。
其中, 移动 RN的位置信息可以是该移动 RN的地理位置信息, 也可以基于移动 RN 的定位算法得出, 还可以基于 RN 当前的服务 DeNB的定位算法得出; 移动 RN的位置信息也可以是移动 RN所属 的 DeNB/Donor Cell 的标识信息或频点信息等能够唯一标识该 DeNB/Donor Cell的信息; 移动 RN的位置信息还可以是上述信息的 组合。
步骤 302, eNB的 OAM根据移动 RN的位置信息确定该移动 RN 可以接入的备选 DeNB/Donor Cdl。
步骤 303, eNB的 OAM系统将备选 DeNB/Donor Cell指示给移 动 RN的服务 DeNB。
具体的, OAM系统可以将备选 DeNB/Donor Cell的标识信息或 频点信息发送给移动 RN的服务 DeNB。
此后, 该移动 RN的 良务 DeNB就可以根据该移动 RN的备选 DeNB/Donor Cell为该移动 RN选择切换的目标 DeNB/Donor Cell了。 根据现有技术, 在 DeNB 为移动 RN选择切换目标时, 可参照移动 RN上报的小区测量结果进行选择。 通过以上流程可以看出, eNB的 OAM系统根据移动 RN的位置 信息为移动 RN选择可接入的备选 DeNB/Donor Cell, 从而, 实现了 在移动 RN的移动过程中为移动 RN配置 DeNB/Donor Cdl。
实施例三
本发明实施例对于安装在列车等有固定线路的交通工具上的移 动 RN , OAM 可以在移动 RN 接入阶段将沿途所需要经过的 DeNB/Donor cell以列表形式一次性发送给移动 RN, 这样移动 RN就 可以根据其当前位置等信息和该 DeNB/Donor cell列表选择可接入的 备选 DeNB/Donor cell了,然后再将该备选 DeNB/Donor cell指示给其 服务 DeNB,以供服务 DeNB为该移动 RN选择切换目标 DeNB/Donor cdl。
在此过程中, RN侧的行为可包括: 在接入过程的阶段一, 上报 自己的运行线路, 并获取对应的 DeNB/Donor cell列表。 在阶段二, 根据当前的 DeNB/Donor cell, 运行方向信息, 以及在阶段一获得的 DeNB/Donor Cell列表, 确定备选 DeNB/Donor Cell列表, 并将确定 的备选 DeNB/Donor Cell列表通知当前的服务 DeNB。
OAM侧的行为可包括: 根据移动 RN上报的运行线路信息, 生 成对应的 DeNB/Donor Cell列表并发送给移动 RN。
服务 DeNB 侧的行为可包括: 根据移动 RN 上报的备选 DeNB/Donor Cell 列表信息为移动 RN选择切换目标 DeNB/Donor Cdl。
参见图 4, 为本发明实施例提供的为移动 RN配置 DeNB/Donor Cell的流程示意图。 其中, 移动 RN上存储有其运行线路上可接入的 DeNB/Donor Cell列表, 列表中 DeNB/Donor Cell可按照该移动 RN 的运行线路进行排序。 如图 4所示, 该流程可包括:
步骤 401 , 移动 RN 根据其运行状态等信息以及存储的 DeNB/Donor Cell列表, 确定备选 DeNB/Donor Cell。
具体的, 移动 RN可根据自己当前的月良务 DeNB/Donor Cell, 以 及其存储的按移动线路顺序排列的可接入的 DeNB/Donor Cell列表, 确定备选 DeNB/Donor Cell, 如可根据可接入的 DeNB/Donor Cell列 表, 选取当前的服务 DeNB/Donor Cell 之前和之后的若干个 DeNB/Donor Cell作为备选 DeNB/Donor Cdl。移动 RN还可以根据自 己当前的服务 DeNB/Donor Cell, 运行方向和其存储的按移动线路顺 序排列的可接入的 DeNB/Donor Cell 列表, 确定备选 DeNB/Donor Cell, 具体的, 根据移动 RN的运行方向, 移动 RN可以在其存储的 按移动线路顺序排列的可接入的 DeNB/Donor Cell列表中选取当前的 服务 DeNB/Donor Cell的下一个或几个 DeNB/Donor Cell作为备选 DeNB/Donor Cdl。
步骤 402, 移动 RN将备选 DeNB/Donor Cell指示给移动 RN的 服务 DeNB。
具体的,移动 RN可采用显式方式或隐式方式将备选 DeNB/Donor Cell指示给移动 RN的服务 DeNB。 所谓显式方式是指移动 RN可以 将备选 DeNB/Donor Cell的标识信息或频点信息发送给该移动 RN的 服务 DeNB。 所谓隐式方式可以是: 移动 RN在向其服务 DeNB上报 小区测量结果时, 只上报对备选 DeNB/Donor Cell的测量结果, 从而 使服务 DeNB可在上报测量结果的 DeNB/Donor Cell中选择移动 RN 的切换的目标 DeNB/Donor Cdl。
此后, 该移动 RN的 良务 DeNB就可以根据该移动 RN的备选 DeNB/Donor Cell为该移动 RN选择切换的目标 DeNB/Donor Cell了。 根据现有技术, 在 DeNB 为移动 RN选择切换目标时, 可参照移动 RN上报的小区测量结果进行选择。
上述流程中, 预先在移动 RN 上配置其运行线路对应的 DeNB/Donor Cell列表的另一种替代方式为: 通过人工方式将其运行 线路对应的 DeNB/Donor Cell列表存储到移动 RN中。
通过以上流程可以看出, OAM系统根据移动 RN的运行线路为 移动 RN确定其沿途可接入的 DeNB/Donor Cell, 进而由移动 RN根 据其位置以及其沿途可接入的 DeNB/Donor Cell , 确定备选 DeNB/Donor Cell,从而实现了在移动 RN的移动过程中为移动 RN配 置 DeNB/Donor Cdl。
实施例四
对于实施例一、 二或三, 在移动 RN进行 DeNB/Donor Cell切换 过程中, 在移动 RN的服务 DeNB获得备选 DeNB/Donor Cell后, 还 可以进一步将移动 RN的备选 DeNB/Donor Cell通知给该移动 RN的 切换目标 DeNB。
具体的, 服务 DeNB可以通过 X2接口或 S1接口向目标 DeNB 发送上述通知。 下面对 X2接口和 S 1接口进行筒单的介绍。
在实际部署网络时, LTE ( Long Term Evolution, 长期演进) 系 统中的基站应用环境, 对于 eNB ( Evolved Node B, 基站) 的实现方 案, eNB与 eNB之间为 X2链路、 eNB与 MME( Mobility Management Entity, 移动性管理实体) /S-GW ( Serving Gateway, 服务网关)之 间为 S1链路;而且 eNB与 eNB之间的 X2链路、 eNB与 MME/S-GW 之间的 S1链路均要采用 SCTP( Stream Control Transmission Protocol, 流控制传输协议)。
X2链路位于 eNB与 eNB之间, SI链路位于 eNB与 MME/S-GW 之间。 S1 链路提供访问无线接入网中的无线资源, 包括控制平面功 能和用户平面功能; S1链路的控制面接口 (S1-MME )提供 eNB与 MME之间的应用协议以及用于传输应用协议消息的信令承载功能; S1链路的用户面接口 ( S1-U )提供 eNB与 S-GW之间的用户面数据 传输功能。 X2链路存在的主要目的是支持 LTE-ACTIVE状态下的 UE 的移动性管理功能; 除此之外, X2链路主要功能还包括负载管理功 能; 小区干扰协调功能; 一般的 X2管理和错误控制功能等。
服务 DeNB可以通过 X2接口,使用 X2-AP( Application Protocol, 应用协议 )消息直接将备选 DeNB/Donor Cell的标识信息或特征信息 发送给目标 DeNB , 如可以使用 X2-AP 消息中的 HANDOVER REQUEST (切换请求) 消息, 即对 HANDOVER REQUEST消息进 行扩展,使其可以携带备选 DeNB/备选 Donor Cell的标识信息或特征 信息。 还可以采用 SI接口,如当不存在 X2接口或 X2接口不可用的情 况下,服务 DeNB可以通过 S1接口,使用 S1-AP消息(如 HANDOVER REQUARE )将备选 DeNB/备选 Donor Cell的标识信息或特征信息发 送给 MME, 再由 MME使用 S1-AP消息转发给目标 DeNB, 如可以 使用 S1-AP 消息中的 HANDOVER REQUEST 消息, 即对 HANDOVER REQUEST 消息进行扩展, 使其可以携带备选 DeNB/Donor Cell的标识信息或特征信息。
在实际操作的过程中, 可能会出现一种情况, 移动 RN刚刚切换 到目标 DeNB, 又需要进行下一次切换。 本发明实施例在移动 RN刚 切换到目标 DeNB且未来得及上报 DeNB/Donor Cell列表就要进行下 一次切换, 此时, 如果目标 DeNB存有 DeNB/Donor Cell列表, 将帮 助其选择目标小区。
