- the mobile Relay node needs to measure the Un port signal quality and switch between different donor cells/donor base stations according to the measurement result.
- LTE-A Long Term Evolution-Advanced
- a fixed Relay node is introduced.
- an important feature of the fixed Relay node is that its position does not change after the power is turned on.

- the donor node information of the relay node is configured by the operator through the OAM system of the relay node.
- the boot process of a fixed relay node is shown in Figure 2 and can be divided into the following two phases:
- Phase I The relay node is attached to the network in the role of the UE to obtain pre-configured parameters.
- the relay node selects a cell (not necessarily a cell supporting the relay), uses the same attach procedure as the UE, attaches to the network, and establishes a data connection with the Relay OAM system.
- the initial configuration parameters are then obtained from the Relay OAM system.
- the initial configuration parameters include: a list of donor cells that can be selected by the relay.
- the Relay node After obtaining the initial configuration parameters, the Relay node uses the same Detach procedure as the UE to detach from the network and trigger Phase II operations.
- Phase II The Relay node is attached to the network in the Relay role and starts working.
- the relay node selects an appropriate donor cell access network according to the donor cell list obtained in phase I, and completes the attach process as a relay.

- the target eNB/Cell of the handover is determined by the currently serving DeNB.
- the DeNB cannot know whether the target eNB/Cell can allow the Relay node to access. This will cause the current DeNB of the mobile Relay node to select a target eNB/Cell that cannot allow the Relay node to access for the mobile Relay node, thereby causing the handover to fail.

- the mobile relay node can only measure the information of the notified donor cell.
- the mobile relay node can perform the measurement result of all the cells that meet the reporting condition.
- the upper condition is configured by the eNB 1 in step 4.
- Step 6 The eNB determines the target donor cell according to the measurement result reported by the mobile relay node.
- the eNB1 only needs to determine the target donor cell according to the measurement result.
- the eNB1 needs to determine the target donor cell to be switched by the relay node according to the measurement result and the donor attribute of the neighboring eNB.
- step 2 in Fig. 8A is as shown in Fig. 8B:
- Step 1 The eNB2 notifies the eNB 1 of its own donor attribute obtained from its own OAM system; the process may be triggered periodically or triggered by an event.
- the triggering event may be: eNB2 initially downloads its own donor attribute from its OAM; or eNB2 obtains its own updated donor attribute from its OAM; or in the response message to eNB1 The own donor attribute is notified to the eNB 1.
- eNB1 is a neighboring eNB of eNB2:
- the specific process of step 2 in Figure 8A may also be as shown in Figure 8C:
- Step 1 eNB2 notifies eNB 1 of its own donor attribute obtained from its own OAM system;
- Step 2 eNB l returns a response message to eNB2, informing eNB2 that it successfully received the message sent in step 1.
- This process can be triggered periodically or by an event.
- the triggering event may be: eNB2 initially downloads its own donor attribute from the OAM; or e B2 obtains its own updated donor attribute from the OAM.
- eNB1 is the neighboring eNB of eNB2:
- eNB1 may return its own donor attribute to eNB2 in the response message. If the donor attribute is notified by the procedure shown in 8C, the existing protocol procedure can be reused, such as the X2 setup process shown in Figure 8D and the eNB configuration update procedure shown in Figure 8E. That is, the donor attribute information can be carried by extending the existing: X2 setup request message, X2 setup response message, eNB configuration update message, and eNB configuration update acknowledge message.
- step 2 in FIG. 8A is as shown in FIG. 8F:
- Step 1 e B2 notifies the MME of its own donor attribute obtained from its own OAM system; in the message sent by e B2, it needs to carry its own identification information and identification information of the target eNB;
- Step 2 The MME forwards the message sent by the eNB2 to the eNB1;
- This process can be triggered periodically or by an event.
- the triggering event may be: eNB2 initially downloads its own donor attribute from its own OAM; or eNB2 obtains its own updated donor attribute from its own OAM.
- eNB l is the neighboring eNB of e B2:
- step 2 in FIG. 8A may also be as shown in FIG. 8G:
- Step 1 The eNB2 notifies the MME of its own donor attribute obtained from its OAM system; in this message, it needs to carry the identity information of itself (ie, e B2 ) and the identification information of the target eNB (ie, eNB1);
- Step 2 MME forwards the message sent by eNB2 to eNB 1;
- Step 3 eNB1 returns a response message to the MME, and confirms that it successfully receives the message sent in step 2; in the message, it needs to carry the identity information of itself (ie, eNB1) and the identity information of the target eNB (ie, e B2 ); Step 4 The MME forwards the message sent by the eNB1 to the eNB2.
- This process can be triggered periodically or by an event.

- eNB1 is a neighboring eNB of eNB2:
- the eNB 1 may return its own donor attribute to the MME in the response message (message 3).
- Step 0 The eNB 1 sends a donor attribute query message to the eNB2, requesting the eNB2 to return its own donor attribute information.
- the eNB2 donor attribute interaction process in FIG. 8C, FIG. 8F, and FIG. 8G may also be triggered by the eNB 1 by sending a donor attribute query message.
- the donor attribute query message sent by the eNB 1 needs to be transited by the MME and sent to the eNB2.
- the eNB l may send a donor attribute query message to obtain the donor attribute of the neighbor eNB/Cell when it becomes the De B of the mobile relay.
- the attribute information of the relay node such as the type of the relay node, may be carried. If the donor attribute query message contains the attribute information of the relay node, e B2 only needs to feedback the donor attribute that matches the attribute of the relay node. For example, the eNB indicates in the donor attribute query message that: the inband relay related donor attribute needs to be queried, and e B2 only needs to reply in the notification donor attribute message: whether the eNB2 can serve as the DeNB of the inband relay node (or which Cell can serve as The donor cell of the inband relay node; there is no need to indicate whether it can act as the DeNB of the outband relay node (or which cells can act as the donor cell of the outband relay node).

Description
目标小区选取方法、 系统和设备 本申请要求在 2011年 2月 14日提交中国专利局、 申请号为 201110037545.6、发明名称 为"目标小区选取方法、 系统和设备"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
本发明涉及无线通信技术领域, 尤其涉及一种目标小区选取方法、 系统和设备。 背景技术
为了改善在高速移动场景下的移动通信服务的质量, 引入了移动中继(Relay )技术。 移动 Relay的网络架构与固定 Relay的网络架构类似, 如图 1所示, 移动 Relay节点 通过无线接口连接到其归属基站下辖的小区, 再经过有线网络连接到核心网。 将该基站称 为移动 Relay节点的施主基站(DeNB ), 将该小区称为移动 Relay节点的施主小区 (donor Cell )。
图 1中共有如下 3个无线接口: 移动 Relay节点与施主基站之间的 Un接口; 归属于 移动 Relay节点的用户终端 ( R-UE )与移动 Relay节点之间的 Uu接口; 用户终端( UE ) 与施主基站之间的 Uu接口。移动 Relay节点在 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。
需要指出的是, 并不是所有的基站( eNB )都适合作为 Relay节点的 DeNB。在现有机 制中, Relay节点的 DeNB和 /或 donor Cell是需要由 Relay节点的操作维护( Operation And Maintenance, OAM ) 系统预先配置给 Relay节点。
移动 Relay节点具有以下一些关键特征:
移动 Relay节点属于网络側节点, 由运营商部署、 管理和维护;
移动 Relay节点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 Relay节点与所服务的用户终端相对静止;
在用户终端看来, 移动 Relay节点就是一个普通基站; 移动 Relay节点管理独立的小 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 Relay 节点的用户终端直接从移动 Relay节点接收调度和控制信令, 并直接向移动 Relay节点发 送上行数据、 控制和反馈信息;
在施主基站看来, 移动 Relay节点类似一个用户终端: 移动 Relay节点通过施主基站 与核心网交互数据;
移动 Relay节点需要对 Un口信号质量进行测量, 并根据测量结果在不同的施主小区 / 施主基站之间切换。
在长期演进升级( Long Term Evolution-Advanced, LTE-A ) 系统中, 引入了固定 Relay 节点, 与移动 Relay节点相比, 固定 Relay节点的一个重要特点是在开机后, 其位置不会 发生变化。
在网络中, 并非所有的 e B都可以作为 Relay节点的 De B, 对于一个 DeNB, 其所 辖的小区也并不一定都可以作为某个 Relay节点的 donor CelL 为了确定哪些 eNB/Cell可 以作为 DeNB/donor Cell, Relay节点在启动后, 开始为 UE服务前, 需要先获知本节点能 够接入的 DeNB/donor Cell信息。
作为一个网络侧节点, Relay节点的 donor Cell信息由运营商经过 Relay节点的 OAM 系统进行配置。 固定 Relay节点的开机流程如图 2所示, 可以分为如下两个阶段:
阶段 I: Relay节点以 UE角色附着到网络, 获取预配置参数;
具体的, 在开机后, Relay节点选择一个小区(不必是支持 Relay的小区), 采用与 UE 相同的附着过程 ( Attach procedure ), 附着到网络, 并建立与 Relay OAM系统的数据连接。 然后从 Relay OAM系统获取初始配置参数,初始配置参数中包括:可供 Relay选择的 donor Cell列表。
在获取初始配置参数后, Relay节点使用与 UE相同的去附着过程 ( Detach procedure ), 从网络去附着, 并触发阶段 II操作。
阶段 II: Relay节点以 Relay角色附着到网络, 开始工作;
具体的, Relay节点根据在阶段 I中获得的 donor Cell列表,选择一个合适的 donor Cell 接入网络, 并以 Relay身份完成附着过程。 在完成一系列的准备工作, 如: 为 Relay节点 选择支持 Relay的移动管理实体 ( MME )、 建立 Relay节点与 DeNB之间的 S1接口和 X2 接口、 建立 Relay节点连接到 Relay OAM系统的数据连接、 建立 Relay节点的用户面承载 等后, Relay节点启动 Uu口, 开始为 R-UE提供服务。
一旦固定 Relay节点进入阶段 Π, 除非出现异常情况, 如 Relay节点重启动、 Un口的 无线链路盾量急剧恶化, 固定 Relay节点将始终处于连接状态。 固定 Relay节点在连接状 态不会变更 donor Cell。
现有技术中存在以下技术问题:
移动 Relay节点在初始开机过程中, 可以重用错误! 未找到引用源。 中所示的流程, 确定并连接到网络预配置的 DeNB/donor CelL 但是, 在移动 Relay节点切换过程中, 切换 的目标 eNB/Cell是由当前服务的 DeNB所确定的。 在目前的协议中, DeNB是无法获知目 标 eNB/Cell是否是可以允许 Relay节点接入的。 这将导致移动 Relay节点的当前 DeNB可 能为移动 Relay节点选择了不能允许 Relay节点接入的目标 eNB/Cell,从而造成切换失败。 发明内容

下面对本发明进行具体说明:
为了描述方便, 定义 eNB的 donor属性可以包括但不限于:
e B是否可以作为 Relay节点的 DeNB;
eNB的哪几个 cell可以作为 Relay节点的 donor Cell;
当网络中存在多种 Relay节点时, 该 eNB可以作为哪几种 Relay节点的 DeNB; 当网络中存在多种 Relay节点时,该 eNB可以做为 donor Cell的小区分别可以为哪几 种 Relay节点服务。
本发明的主要思想: eNB获取邻接 eNB的 donor属性, 以便供移动 Relay节点进行切 换时, 选择目标 DeNB/donor Cell使用。
本发明只涉及 Relay节点为 R-UE提供正常工作后, 在 DeNB之间切换过程中, 目标 donor cell的确定方法。对于 Relay节点开机后, 第一次选择 donor Cell接入到网络的过程, 本专利不做限定。即移动 Relay节点可以采用错误!未找到引用源。所示方法获取初始 donor eNB/Cell列表, 也可以以其他方式确定 donor Cell。
eNB的 OAM系统行为包括:
eNB 的 OAM系统将每个 eNB的 donor属性配置到对应的 eNB;
当 eNB的 donor属性需要变更时, eNB的 OAM将变更后的 eNB donor属性通知给对 应的 e B。
eNB侧行为包括:
eNB从 eNB的 OAM系统获取其 donor属性;
eNB与相邻的 eNB之间交互 donor属性;
当 eNB的 donor属性发生变更时, 需要通过相应的属性更新过程通知邻 eNB;
eNB可以对 Relay节点的测量进行控制, 即 eNB对 Relay节点进行测量配置, 要求 Relay节点只对可以故 donor cell的邻小区进行测量;
若 eNB不限制 Relay节点所需测量的邻小区,则服务 DeNB需要根据 Relay节点的测
量上报结果和邻小区的 donor属性, 确定可以作为目标小区的邻小区。
本发明实施例如下:
如图 8A所示。 eNBl是移动 Relay节点的当前服务 DeNB , eNB2是 eNBl的邻 e B。 eNBl确定移动 Relay节点的目标施主小区的过程如下:
步骤 1 : eNB2从自己的 OAM系统下载配置参数, 配置参数中包括 eNB的 donor属 性;
步骤 2: eNB2与邻接的所有 eNB (图中的 eNBl )交互 donor属性。通过该过程: eNBl 获得 e B2的 donor属性; 通过与不同邻 eNB的多次交互过程, eNBl可以获取所有邻接 eNB的 donor属性。
该过程由 eNB2发起,发起时间可以是 eNB2初次从自己的 OAM处获得自己的 donor 属性后, 还可以是 e B2从自己的 OAM处获得自己更新的 donor属性后。
步骤 3: eNB 1可以根据获得的邻 eNB的 donor属性,将自己以及邻 eNB可以作为 donor cell的小区信息发送给移动 Relay节点; 该步骤为可选步骤。
所述 donor cell的小区信息可能是: 小区标识信息、 小区频点信息、 小区归属的 eNB 的标识信息等。
步驟 4: eNB 1为移动 Relay节点配置测量参数;
步骤 5: 移动 Relay节点根据 eNB l的配置, 上报测量结果:
如果 eNBl曾将 donor cell的信息发送给移动 Relay节点,移动 Relay节点可以只上 4艮 对所通知的 donor cell的测量信息;
如果 eNBl没有将 donor cell的信息发送给移动 Relay节点,移动 Relay节点可以上^ ¾ 所有满足上报条件的小区的测量结果;
所述上 4艮条件由 eNB l在步骤 4中进行配置。
步骤 6: eNB l根据移动 Relay节点上报的测量结果, 确定目标 donor Cell。
如果移动 Relay节点只上报对所通知的 donor cell的测量信息, eNBl只需要根据测量 结果即可确定目标 donor cell。
如果移动 Relay节点上报了所有满足上报条件的小区的测量结果, eNBl 需要根据测 量结果和邻 eNB的 donor属性, 确定 Relay节点切换的目标 donor cell。
在该实施例中, 图 8A中步骤 2的具体流程如图 8B所示:
步驟 1: eNB2将从自己的 OAM系统处获得的自身的 donor属性通知给 eNB 1; 该过程可以周期性触发,也可以事件触发。 当该过程由事件触发时,触发事件可以是: eNB2初始从自己的 OAM下载自己的 donor属性; 或 eNB2从自己的 OAM处获得自己更 新的 donor属性; 或是在给 eNB 1的响应消息中将自身的 donor属性通知给 eNB 1。
图 8B中, eNBl是 eNB2的相邻的 eNB:
图 8A中步驟 2的具体流程还可能如图 8C所示:
步骤 1: eNB2将从自己的 OAM系统处获得的自身的 donor属性通知给 eNB 1; 步骤 2: eNB l向 eNB2返回响应消息, 通知 eNB2其成功接收步骤 1中发送的消息。 该过程可以周期性触发,也可以事件触发。 当该过程由事件触发时,触发事件可以是: eNB2初始从 OAM下载自己的 donor属性; 或 e B2从 OAM处获得自己更新的 donor属 性。
图 8C中, eNBl是 eNB2的邻 eNB:
作为一种可选优化, eNBl可能在响应消息中将自己的 donor属性返回给 eNB2。 如果采用 8C所示的流程通知 donor属性, 可以重用现有的协议过程, 如图 8D所示 的 X2建立过程和图 8E所示的 eNB configuration update过程。 即: donor属性信息可以通 过扩展现有的: X2 setup request消息 , X2 setup response消息, eNB configuration update消 息 , eNB configuration update acknowledge消息来携带。
当 eNB 1和 e B2之间没有 X2接口或 X2接口不可用时, 该实施例中, 图 8A中步驟 2的具体流程如图 8F所示:
步骤 1 : e B2将从自己的 OAM系统处获得的自身的 donor属性通知给 MME;在 e B2 发出的消息中, 需要携带自己的标识信息和目标 eNB的标识信息;
步骤 2: MME将 eNB2发出的消息转发给 eNB 1;
该过程可以周期性触发,也可以事件触发。 当该过程由事件触发是,触发事件可以是: eNB2初始从自己的 OAM下载自己的 donor属性; 或 eNB2从自己的 OAM处获得自己更 新的 donor属性。
图 8F中, eNB l是 e B2的邻 eNB:
当 eNB 1和 eNB2之间没有 X2接口或 X2接口不可用时, 该实施例中, 图 8A中步骤 2的具体流程还可能如图 8G所示:
步驟 1: eNB2将从自己的 OAM系统处获得的自身的 donor属性通知给 MME; 在该 消息中, 需要携带自己 (即 e B2 ) 的标识信息和目标 eNB (即 eNBl ) 的标识信息; 步驟 2: MME将 eNB2发出的消息转发给 eNB 1;
步骤 3 : eNBl 向 MME返回响应消息, 确认其成功接收步骤 2中发送的消息; 在该 消息中, 需要携带自己 (即 eNBl ) 的标识信息和目标 eNB (即 e B2 ) 的标识信息; 步驟 4: MME将 eNBl发出的消息转发给 eNB2。
该过程可以周期性触发,也可以事件触发。 当该过程由事件触发是,触发事件可以是: eNB2初始从自己的 OAM下载自己的 donor属性; 或 eNB2从自己的 OAM处获得自己更 新的 donor属性。
图 8G中, eNBl是 eNB2的邻 eNB:
作为一种可选优化, eNB l可能在响应消息(消息 3 ) 中将自己的 donor属性返回给 MME。
在图 8B、 图 8C、 图 8F、 图 8G中, eNB2发出的通知 donor属性可以由 eNB l触发。 例如, 如图 8H中步骤 0的 "donor属性查询过程" 所示:
步骤 0: eNB 1向 eNB2发送 donor属性查询消息, 要求 eNB2返回自身的 donor属性 信息。
同理, 图 8C、 图 8F、 图 8G中的 eNB2 donor属性交互过程也可以是由 eNB l通过发 送 donor属性查询消息触发。 在图 8F、 图 8G中对应的过程中, 由 eNB l发出的 donor属 性查询消息需要经过 MME中转后, 发送到 eNB2。
eNB l可以在成为移动 Relay的 De B时,发送 donor属性查询消息,获取邻 eNB/Cell 的 donor属性。
作为一种优化 ,在 donor属性查询消息中,可以携带 Relay节点的属性信息 ,例如 Relay 节点的类型。 如果 donor属性查询消息中包含 Relay节点的属性信息, 则 e B2只需要反 馈与该 Relay节点的属性相匹配的 donor属性。例如: eNB l在 donor属性查询消息中指示: 需要查询 inband Relay相关的 donor属性, e B2在通知 donor属性消息中, 就只需回复: eNB2是否可以作为 inband Relay节点的 DeNB (或哪些 Cell可以作为 inband Relay节点的 donor Cell ); 而无需指示其是否可以作为 outband Relay节点的 DeNB (或哪些 Cell可以作 为 outband Relay节点的 donor Cell )。
