Description

自组织网络信息传输方法、 系统和设备 本申请要求在 2011年 9月 30日提交中国专利局、 申请号为 201110301981. X、 发明名称为
"自组织网络信息传输方法、 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领域,尤其涉及一种自组织网络信息 SON传输方法、 系统和设备。 背景技术
在长期演进 ( Long Term Evolution, LTE )系统中, 宏基站( e B )直接连接到核心网, 家庭基站( Home eNodeB, He B )既可以直接连接到核心网, 也可以通过一个称为 He B 网关( HeNB Gateway )的设备连接到核心网。 由于该设备的引入,导致了网络拓朴的改变, 使得 X2接口有两种形式。 一种是直接 X2接口, 一种是间接 X2接口。
所谓直接 X2接口,是指两个基站之间建立的点到点的 X2接口,这两个基站可以是两 个宏 eNB, 也可以是两个 HeNB, 也可以是一个宏基站和一个 He B。
所谓间接 X2接口,是指两个基站之间通过 HeNB网关建立的 X2接口,故也称为 HeNB 网关代理的 X2接口, 这两个基站中至少有一个基站是 He B。 这种 X2接口实际上是由两 个基站分别跟 HeNB 网关建立的点到点的 X2接口组成的。 在协议应用层, 这两个基站将 这种 X2接口作为一个逻辑接口, 跟直接 X2接口的功能是一样的。
两个宏 eNB之间不可能建立间接 X2接口, 只有其中至少一个连接到 HeNB网关的两 个 HeNB之间, 或者, 一个宏 eNB与一个连接到 HeNB 网关的 HeNB之间, 才可能建立 间接 X2接口。
图 1为直接 X2接口的示意图, 两个基站之间有点到点连接的 X2接口。
图 2为间接 X2接口的示意图, 即一个宏 eNB (或者直接连接到核心网的 HeNB )跟 HeNB网关有一段 X2接口, 而 HeNB网关到 HeNB还有另一段 X2接口。但无论是宏 eNB 还是 HeNB都将这两段接口组合在一起看作一条逻辑 X2接口。
在现有标准协议中, X2接口的建立是通过两个信令过程实现的, 一个是自组织网络 ( Self Organising Networks , SON )信息获取过程 , 一个是 X2接口建立过程。 SON信息获 取过程, 是为了获取对方基站的传输层 IP地址, 只有获得传输层 IP地址后, 两个基站才 能建立传输层连接 , 并且在此基础上建立 X2接口。 SON信息获取过程如图 3所示:
步骤 1 : 源基站 X发送基站配置传输(eNB Configuration Transfer ) 消息到移动性管 理实体 (Mobility Management Entity, MME ), 该消息中包含源基站的标识 (ID )和跟踪 区标识( TAI )、 目标基站的 ID和 TAI, 还可以包含源基站的传输层 IP地址;
步骤 2: MME 收到 eNB Configuration Transfer消息后, 通过目标基站的 ID寻址到目 标基站, 将携带 SON 信息请求指示及以上信息的移动性管理实体配置传输 (MME Configuration Transfer ) 消息发送给目标基站;
步骤 3: 目标基站 Y收到 MME Configuration Transfer消息后, 可以保存基站 X的 IP 地址, 然后向 MME发送 eNB Configuration Transfer消息, 其中包含 SON信息响应指示、 自身 ID、 发送请求的基站 X的 ID , 以及自身的传输层 IP地址;
步骤 4: MME将响应消息的内容通过 MME Configuration Transfer 消息发送给基站 X; 基站 X收到消息后就获得了基站 Y的传输层 IP地址。
当基站 X获得目标基站 Y的传输层 IP地址后, 即可建立传输层连接及 X2接口。 传 输层连接建立是已有方法, 不在本专利讨论范围内。 X2接口建立的信令过程如图 4所示: 步骤 1 : 基站 X在建好的传输层链路上向目标基站 Y发送 X2建立请求( X2 Setup
Request ) 消息, 其中包含了基站 X的 ID、 服务小区列表, 还可以包含每个本地服务小区 的邻区列表;
步骤 2:基站 Y收到 X2 Setup Request消息后,向对端基站返回 X2建立响应( X2 Setup Response ) 消息, 其中包含了基站 Y的 ID和服务小区列表, 也可以包含每个本地小区的 邻区列表。
在实现本发明的过程中, 发明人发现现有技术中存在以下技术问题:
现有技术中并没有针对间接 X2接口建立的 SON信息获取过程的具体实现方案,进而使 得如何建立间接 X2接口也没有具体实现方案。 发明内容

首先做出如下分析:
在建立间接 X2接口时,由于 HeNB 网关的参与, SON信息获取过程发生了一些变化,
SON信息获取过程可以有两种实现方式。
方式一: HeNB GW代替目标 HeNB做应答, 如图 5所示:
步骤 1: 源基站 X 向 MME发送 e B Configuration Transfer消息,其中包含 SON信息 请求指示、 源基站的 ID和 TAI、 目标基站的 ID和 TAI, 还可以包含源基站的传输层 IP地 址;
步骤 2: MME 收到 eNB Configuration Transfer消息后, 通过目标基站的 ID及 TAI寻 址到目标基站连接的 HeNB GW, 将消息中的内容携带在 MME Configuration Transfer消息 中后发送到 HeNB GW;
步骤 3: HeNB GW收到 MME Configuration Transfer消息后, 要代替目标 HeNB Y做 应答, 因为此时 HeNB GW是一个代理节点, 源基站实际上需要跟 HeNB GW建立一段 X2。 HeNB GW发送消息 eNB Configuration Transfer给 MME, 其中包含 SON信息响应指 示、 目标 HeNB Y的 ID , 发送请求的源基站 X的 ID、 以及 HeNB GW 的传输层 IP地址; 步骤 4: MME将 NB Configuration Transfer中的内容通过 MME Configuration Transfer 发送给源基站 X 基站 X收到后,认为获得的 IP地址就是目标 HeNB Y的传输层 IP地址。
方式二: HeNB GW修改目标 HeNB返回的响应消息, 如图 6所示:
步骤 1: 源基站 X 向 MME发送 eNB Configuration Transfer消息,其中包含 SON信息 请求指示、 源基站的 ID和 TAI、 目标基站的 ID和 TAI, 还可以包含源基站的传输层 IP地 址;
步骤 2: MME 收到 eNB Configuration Transfer消息后, 通过目标基站的 ID及 TAI寻 址到目标基站连接的 HeNB GW,将消息中的内容包含在 MME Configuration Transfer 消息 中发送到 HeNB GW; 步骤 3 : HeNB GW将 MME Configuration Transfer消息原封不动地转发给目标 HeNB
Y;
步骤 4: 目标 HeNB收到 MME Configuration Transfer 消息后, 向 HeNB GW返回 eNB Configuration Transfer消息, 其中包含 SON信息响应指示、 HeNB Y的 ID、 发送请求的源 基站的 ID、 以及 HeNB Y的传输层 IP地址;
步骤 5: HeNB GW收到 HeNB Y的响应消息后, 将其中 HeNB Y的传输层 IP地址替 换为 HeNB GW 的传输层 IP地址, 其它信息不变, 然后将修改后的 eNB Configuration Transfer消息发送给 MME;
步骤 6: MME将 eNB Configuration Transfer中内容通过 MME Configuration Transfer 消息发送给源基站 X 基站 X收到后, 认为获得的 IP地址就是目标 HeNB Y的传输层 IP 地址。
在获取到所需的传输层 IP地址后, 就要建立 X2接口。 如前所述, 间接 X2接口是由 两段 X2接口组成, 一段是 HeNB Y跟 HeNB GW之间的 X2接口, 另一段是基站 X跟 HeNB GW之间的 X2接口。
间接 X2接口的建立过程如图 7所示, 在 HeNB Y开机后, 可以通过配置信息获知
HeNB GW的传输层 IP地址, 所以 HeNB Y不需要发起 SON信息获取过程, 就可以建立 到 HeNB GW 的 X2接口。 之后, 经过一段网络运行时间, 基站 X通过前述的 SON信息 获取过程获得 HeNB Y的传输层 IP地址后, 建立与 HeNB GW间的传输层连接, 然后发送 X2 Setup Request 消息, 消息中携带源基站 X的 ID、服务小区列表。 由于基站 X获得的传 输层地址是 HeNB GW的地址,而非 HeNB Y的地址,因此这条请求消息最终发送到 HeNB GW。 HeNB GW收到 X2 Setup Request消息,返回 Χ2 Setup Response消息,其中包含 HeNB GW 的 ID , 及连接到这个网关的一些 HeNB 的小区, 其中包括有 HeNB Y的小区。 至此, 基站 X与 HeNB Y之间的间接 X2接口建立完成。
在以上间接 X2接口建立过程中, 源基站 X发起的 X2接口建立的目标是 HeNB Y, 虽 然 HeNB Y 的 ID没有包含在 X2建立请求消息中,但基站 X知道这一点。但是, 从 HeNB GW返回的 X2建立响应消息中包含的 ID是 HeNB GW 的 ID ,不是 HeNB Y的 ID。这样, 按照正常的处理机制, 源基站 X会将此响应消息当作一条错误消息, 而不是期望接收的响 应, 最终导致基站 X到 HeNB GW之间的 X2接口无法建立。
因此, 本发明实施例提出了如下 SON信息传输方法, 本方法中, 家庭基站网关在响 应 MME发送的 MME Configuration Transfer消息时,需要将家庭基站网关的标识信息发送 给 MME, 使得源基站也能够得到家庭基站网关的标识信息。 参见图 8,本发明实施例提供的用于实现家庭基站网关代理的 X2接口建立的 SON信 息传输方法中, 针对家庭基站网关侧的具体流程如下:
步骤 80: 家庭基站网关接收 MME发送的 MME Configuration Transfer消息,该 MME Configuration Transfer消息中携带源基站的标识信息和目标家庭基站的标识信息;
步骤 81: 家庭基站网关向 MME发送 eNB Configuration Transfer消息, 以指示 MME 将该 eNB Configuration Transfer消息中携带的信息发送给所述源基站;该 eNB Configuration Transfer 消息中携带源基站的标识信息、 目标家庭基站的标识信息、 家庭基站网关的传输 层 IP地址和家庭基站网关的标识信息。
进一步的, 在家庭基站网关接收 MME发送的 MME Configuration Transfer消息之后、 并且向所述 MME发送 eNB Configuration Transfer消息之前, 家庭基站网关可以将步骤 80 中接收到的 MME Configuration Transfer消息发送给目标家庭基站;然后接收目标家庭基站 返回的 eNB Configuration Transfer消息, 接收到的 eNB Configuration Transfer消息中携源 基站的标识信息、 目标家庭基站的标识信息和目标家庭基站的传输层 IP地址信息;
相应的, 步骤 81中家庭基站网关向 MME发送 eNB Configuration Transfer消息, 其 具体实现如下:
家庭基站网关对接收到的 eNB Configuration Transfer消息进行如下修改: 将接收到的 eNB Configuration Transfer消息中携带的目标家庭基站的传输层 IP地址信息, 替换为家庭 基站网关的传输层 IP地址信息, 并在接收到的 eNB Configuration Transfer消息中增加家庭 基站网关的标识信息; 然后, 家庭基站网关向 MME 发送修改后的 eNB Configuration Transfer消息。
本方法中, 源基站可以为宏基站或者直接连接到核心网的家庭基站。
参见图 9,本发明实施例提供的用于实现家庭基站网关代理的 X2接口建立的 SON信 息传输方法中, 针对 MME侧的具体流程如下:
步骤 90 : MME 接收源基站发送的 eNB Configuration Transfer 消息, 该 eNB Configuration Transfer消息中携带源基站的标识信息和目标家庭基站的标识信息;
步骤 91 : MME 向目标家庭基站连接到的家庭基站网关发送 MME Configuration Transfer消息, 该 MME Configuration Transfer消息中携带源基站的标识信息和目标家庭基 站的标识信息;
步骤 92: MME接收家庭基站网关发送的用于响应步骤 91 中的 MME Configuration Transfer消息的 eNB Configuration Transfer消息,该家庭基站网关发送的 eNB Configuration Transfer 消息中携带源基站的标识信息、 目标家庭基站的标识信息、 家庭基站网关的传输 层 IP地址和所述家庭基站网关的标识信息;
步骤 93: MME向源基站发送 MME Configuration Transfer消息,该 MME Configuration Transfer 消息中携带源基站的标识信息、 目标家庭基站的标识信息、 家庭基站网关的传输 层 IP地址和家庭基站网关的标识信息。
本方法中, 源基站可以为宏基站, 或者直接连接到核心网的家庭基站。
参见图 10, 本发明实施例提供的用于实现家庭基站网关代理的 X2接口建立的 SON 信息传输方法中, 针对源基站侧的具体流程如下:
步骤 101 :源基站向 MME发送 eNB Configuration Transfer消息,该 e B Configuration Transfer消息中携带源基站的标识信息和目标家庭基站的标识信息;
步骤 102:源基站接收 MME发送的 MME Configuration Transfer消息,并保存该 MME
Configuration Transfer消息中携带的信息; 该 MME Configuration Transfer消息中携带源基 站的标识信息、 目标家庭基站的标识信息、 家庭基站网关的传输层 IP地址和家庭基站网关 的标识信息。
进一步的, 在源基站保存该 MME Configuration Transfer消息中携带的信息后, 可以 记录所述家庭基站网关与所述目标家庭基站具有代理关系, 比如通过设置标志位的方式来 记录代理关系; 然后, 源基站可以在使用家庭基站网关的传输层 IP地址, 与家庭基站网关 建立传输层连接后, 发起 X2接口建立过程:
源基站向家庭基站网关发送 X2建立请求消息;
源基站接收所述家庭基站网关发送的 X2建立响应消息, 该 X2建立响应消息中携带 家庭基站网关的标识信息以及目标家庭基站的小区信息;
源基站在根据记录的信息确定所述家庭基站网关与所述目标家庭基站具有代理关系 后, 确定成功建立与目标家庭基站间的 X2接口。
本方法中, 源基站可以为宏基站, 或者直接连接到核心网的家庭基站。
下面对本发明进行具体说明:
本发明主要思想是在间接 X2 建立前的 SON信息获取过程中, He B GW在收到
MME发来的 SON信息请求消息后, 在响应消息中除了包含目标 HeNB的 ID、 源基站的 ID 夕卜, 还要包含 HeNB GW 自己的 ID。
具体实现方式一, HeNB GW在收到 MME发来的 SON信息请求消息后, HeNB GW 代替目标 HeNB做应答, 在响应消息中除了包含目标 HeNB的 ID、 源基站的 ID 夕卜, 还包 含 He B GW 自己的 ID, 如图 11A所示。
具体实现方式二, HeNB GW在收到 MME发来的 SON信息请求消息后, 将请求消 息原封不动地转发给目标 HeNB , 在 HeNB GW在收到目标 HeNB返回的响应消息后, 将 响应消息中目标 HeNB的传输层 IP地址替换为自己的 IP地址, 并且在消息中增加 HeNB GW 的 ID, 然后将修改后的响应消息发送给 MME, 如图 11B所示。
当源基站收到响应消息后, 发现除了源基站和目标基站的 ID, 还有一个 HeNB GW 的 ID, 则源基站知道这个响应是由 HeNB GW代理应答或做了修改, 记录这个 HeNB GW 与目标 HeNB具有代理关系。随后,源基站发起 X2建立,其目标可以是原来的目标 HeNB, 也可以是 HeNB GW, 返回的 X2 建立响应消息中包含的是 HeNB GW ID, 这是源基站所 期望的响应。 以上机制保证了请求基站跟 HeNB GW之间能够正确建立 X2接口。
以下通过实施例说明本发明方法。

步骤 6. MME将 eNB Configuration Transfer中的信息通过 MME Configuration Transfer 消息发送给基站 A。基站 A收到后,认为获得的 HeNB GW T的 IP地址就是 HeNB B的传 输层 IP地址, 并记录 HeNB GW T与 HeNB B具有代理关系。 步骤 7. eNB A根据获得的 HeNB GW T的 IP地址与 HeNB GW T 建立传输层连接, 然后发送 X2 建立请求消息。

步骤 9. eNB A收到 X2 建立响应消息,发现其中包含 HeNB GW T的 ID ,还有 HeNB
