Description

一种直接接口选择建立的方法及系统 技术领域
本发明涉及无线蜂窝通信系统, 尤其涉及一种直接接口选择建立的方 法及系统。 背景技术
家用基站是一种小型、 低功率的基站, 部署在家庭及办公室等室内场 所, 主要作用是为了给用户提供更高的业务速率并降低使用高速率服务所 需要的费用, 同时弥补已有分布式蜂窝无线通信系统覆盖的不足。 家用基 站的优点是实惠、 便捷、 低功率输出、 即插即用等。
在长期演进(LTE ) 系统或通用移动通信系统(UMTS )下, 家庭基站 用户通过家庭基站接入网连接到核心网网络, 如图 1 所示。 家庭基站接入 网由家庭基站和家庭基站网关共同组成。 家庭基站网关主要执行的功能为: 验证家庭基站的安全性, 处理家庭基站的注册和接入控制, 负责交换核心 网和家庭基站的数据。 家庭基站管理系统对家庭基站进行运行维护管理, 根据运营商要求配置和控制家庭基站, 最主要为家庭基站实现配置管理功 能, 其中包括位置信息的核实、 为家庭基站进行参数配置, 主要涉及到核 心网 (CN )级别的参数配置、 无线接入网 (RAN, Radio Access Network ) 侧的参数配置以及射频 (RF, Radio frequency ) 的参数配置。
家庭基站可以部署于学校、 商场等公共场所。 对于同一个企业内部, 可能部署很多的家庭基站。 为了加快切换的速度, 需要考虑家庭基站之间 的直接接口。 对于企业级场景, 建立家庭基站之间的直接接口是合理的, 因为这样不仅仅可以加快切换还可以减轻核心网的负担, 并且直接接口的 建立以及维护也方便。以下对现有普通的 X2直接接口建立的流程简单介绍 下:
如图 2所示的现有普通的 X2直接接口建立的流程中, 首先: eNB 1在 没有目标基站 eNB2 的地址信息时, 根据自动邻区关系 (ANR )或者操作 管理维护系统(OAM ) 配置的邻区或者 eNB2的信息获取 eNB2 IP地址所 需的信息, 包括 eNB ID以及 eNB所在的跟踪区标识(TAI )。 然后, eNBl 向移动管理实体 ( MME )发送 ENB配置传输消息( ENB CONFIGURATION TRANSFER ), 该消息里面包含 eNBl的标识以及 eNBl的 TAI、 eNB2的标 识以及 eNB2的 TAI, 以及 IP获取请求指示; MME收到该消息后根据里面 的 eNB2 的 TAI 进行路由, 然后使用 MME 配置传输消息 ( MME CONFIGURATION TRANSFER ) 进行消息重新封装后发送到目标基站 eNB2。 eNB2收到 MME CONFIGURATION TRANSFER消息后, 读取里面 的信息, 判断是否是 IP 地址获取请求, 生成 ENB CONFIGURATION TRANSFER, 里面携带自己的 IP地址, 并且表明是对 IP地址获取的响应, 并且包含 eNBl和 eNB2的 TAI和基站标识, 发送该消息到 MME。 MME 根据目标基站 eNB 1的 TAI信息,使用 MME CONFIGURATION TRANSFER 封装后发送到 eNBl , eNBl收到 MME CONFIGURATION TRANSFER消息 后, 根据 IP地址响应内容获取到 eNB2的 IP地址。 eNBl在收到了 eNB2 的传输地址以后,向 eNB2发送 X2建立请求消息, eNB2收到 X2建立请求 消息后判断是否要建立 X2直接接口,如果要建立 X2直接接口,则向 eNBl 发送 X2建立响应消息。 完成 X2直接接口的建立, 否则, 向 eNBl发送 X2 建立失败消息。
宏基站间的 X2直接接口的建立相对简单,因为每个小区都隶属于某一 特定的宏基站。 引入了家庭基站概念以后, 由于家庭基站网关的存在, 打 破了原先扁平的网络结构。 家庭基站网关既有宏基站功能, 同时又是所属 家庭基站的管理网元。 因此源 eNB与家庭基站网关所管辖的家庭基站的直 接接口建立, 可以选择建立在源 eNB和家庭基站网关之间, 此时家庭基站 网关执行类似代理的功能而与其所管辖的家庭基站交互; 或者, 源 eNB与 家庭基站网关所管辖的家庭基站的直接接口建立, 也可以选择直接建立在 源 eNB与家庭基站之间, 此时家庭基站网关仅可选的执行对直接接口上的 消息的路由。 引入了家庭基站后, 在家庭基站通过家庭基站网关接入核心 网网元时, 目前尚未存在可选的直接接口建立方案以便进行多种直接接口 建立方案的选择, 即: 目前迫切需要一种直接接口选择建立的方案。 发明内容
有鉴于此, 本发明的主要目的在于提供一种直接接口选择建立的方法 及系统, 能实现可选的直接接口建立, 以便进行多种直接接口方案的选择。
为达到上述目的, 本发明的技术方案是这样实现的:
一种直接接口选择建立的方法, 该方法包括: 目标网元通过目标网关 接入核心网网元时, 由源侧或目标侧选择与目标网关和 /或目标网元建立直 接接口。

本发明的基本思想是: 目标网元通过目标网关接入核心网网元时, 由 源侧或目标侧选择与目标网关和 /或目标网元建立直接接口。 本文的核心网 网元包括 LTE系统下的 MME、 或 UMTS系统下的移动交换中心( MSC ) I 服务 GPRS支持节点 ( SGSN ), 不作赘述。
下面结合附图对技术方案的实施作进一步的详细描述。
一种直接接口选择建立的方法, 该方法主要包括以下内容:
目标网元通过目标网关接入核心网网元时, 由源侧或目标侧选择与目 标网关和 /或目标网元建立直接接口。 其中, 源侧包括源网元; 目标侧包括 目标家庭基站网关或目标家庭基站。
下面以目标网元的类型为家庭基站, 目标网关的类型为家庭基站网关 的情况进行说明:
家庭基站通过家庭基站网关连入核心网网元时的直接接口选择建立的 过程中, 可以由源侧或者目标侧选择直接接口的建立, 可选的与家庭基站 网关和 /或家庭基站建立直接接口。
这里, 在家庭基站通过家庭基站网关连入核心网网元时, 源侧可以根 据可选的直接接口建立方式的信息, 选择不同的直接接口建立方式, 该直 接接口建立方式包括: 与家庭基站网关建立直接接口、 或者与家庭基站建 立直接接口、 或者与家庭基站网关和家庭基站都建立直接接口。 以下针对 源侧或者目标侧所选择的不同的直接接口建立方式进行具体阐述。
情况一: 由源侧选择直接接口建立方式。 此种情况下, 所述可选的直 接接口建立方式的信息为: 目标家庭基站网关和 /或目标家庭基站的地址信 息。
在源侧获取目标家庭基站传输层 (TNL )地址的过程中, 可以同时获 得目标家庭基站网关和 /或目标家庭基站的地址信息。 源侧根据获得的所述 地址信息, 选择与目标家庭基站网关和 /或目标家庭基站建立直接接口, 并 发起直接接口的建立。
这里, 目标家庭基站网关和目标家庭基站对网元发送的获取 TNL地址 响应时,可以由目标家庭基站网关和目标家庭基站分别在 TNL地址获取响 应中填写各自的信息; 也可以由目标家庭基站网关填写目标家庭基站网关 自身和目标家庭基站的信息。 其中, 填写的所述信息, 即: 目标家庭基站 网关以及目标家庭基站的信息: 包括目标家庭基站网关的标识、 目标家庭 基站网关的传输层地址、 目标家庭基站的标识、 目标家庭基站的传输层地 址中的至少一种; 填写的所述信息除了以上信息中的至少一种外, 可选的 还可以包括目标网元的类型, 目标网元的类型可以与以上信息中的至少一 种配合使用。 目标网元为目标家庭基站或目标家庭基站网关。 本文的传输 层地址包括网际协议(IP )地址, 不作赘述。
情况二: 由目标侧选择直接接口建立方式。 此种情况下, 所述可选的 直接接口建立方式的信息为: 目标家庭基站网关和 /或目标家庭基站的地址 信息。
在目标侧获取目标家庭基站 TNL地址的过程中, 目标侧选择向源侧返 回选定的目标家庭基站网关和 /或目标家庭基站的信息; 源侧根据获得的所 述信息, 向目标侧选定的网元发起直接接口的建立。 其中, 选定的目标家 庭基站网关和 /或目标家庭基站的信息是为了用于指向目标侧选定的网元, 所述选定的网元可以为目标家庭基站网关和 /或目标家庭基站。
这里, 选定的目标家庭基站网关和 /或目标家庭基站的信息包括: 目标 家庭基站网关的标识、 目标家庭基站网关的传输层地址、 目标家庭基站的 标识、 目标家庭基站的传输层地址、 目标网元的类型中的至少一种。
这里需要指出的是: 情况一和情况二的主要区别是: 情况一在源侧选 择时, 目标侧在返回的信息中可以包含多个地址信息, 由源侧从中自行选 择后再对选择的网元发起直接接口的建立; 而情况二目标侧选择时, 在返 回的信息中包含的是目标侧已选定的地址信息, 由目标侧直接向选定的地 址信息所指向的选定网元发起直接接口的建立。 源侧为源网元, 目标侧为目标网元时, 无论是针对源网元还是针对目 标网元, 二者的网元类型都可以包括: 宏基站或家庭基站。
以下对本发明进行举例阐述。
方法实施例 1: 源侧判断选择目标网元建立直接接口的流程。
本方法实施例描述的是在地址获取阶段, 目标网元返回地址信息后, 由源侧决定向目标家庭基站还是家庭基站网关建立直接接口的情况。 为了 描述方便,我们用 eNBl来表示源基站、 eNB2来表示目标基站,其中 eNBl 可以是普通的宏基站也可以是家庭基站以及家庭基站网关, eNB2 通过 HeNB GW接入 MME。 其中 Cell2属于 eNB2的管理。 如图 3所示, 本方法 实施例选择建立直接接口的流程包括以下步骤:
步骤 101 : eNBl根据 ANR, 获取到 Cell2的信息。
这里, 信息中包含了 Cell2所属的 TAI、 公众陆地移动通信网( PLMN ) 以及 Cell2的小区标识。 eNBl决定向 Cell2所属的 eNB2建立 X2直接接口, 通过配置的路由信息, 或者从 Cell2的小区标识中获得 eNB2的标识。
步骤 102: eNBl向 MME发送 eNB CONFIGURATION TRANSFER消 息, 该消息里面包含 eNB2的标识以及 TAI , 以及 IP获取请求指示。
步骤 103: MME在收到 eNB CONFIGURATION TRANSFER消息后, 根据其中 eNB2 的 TAI 进行路由, 向目标基站 eNB2 发送 MME CONFIGURATION TRANSFER。 该消息用来封装 eNB CONFIGURATION TRANSFER消息里面的内容。
步骤 104a: HeNB GW收到 MME CONFIGURATION TRANSFER, 如 果 HeNB GW保存有 eNB2的 IP地址及 eNB ID等建立直接接口必要的信息, 可以由 HeNB GW此时构造 eNB CONFIGURATION TRANSFER消息, 并 在消息中同时填写 HeNB GW本身以及 eNB 2的 IP地址等建立直接接口必 要的信息, 比如 HeNB ID、 HeNB IP Address、 HeNB GW ID, HeNB GW IP Address。 消息发送给 MME, 其中目标基站标识为 eNBl的标识。
步骤 104b: HeNB GW收到 MME CONFIGURATION TRANSFER后, 将该消息转发到 eNB2, 获取 eNB2的用于建立直接接口的传输地址;
步骤 105: eNB2通过 ENB CONFIGURATION TRANSFER消息, 向 HeNB GW返回自己用于建立直接接口的传输地址。 该消息中包括: HeNB ID、 HeNB IP Address„
步骤 106: HeNB GW在收到了包含 eNB2的地址的步骤 105中的消息 后,重新构造 ENB CONFIGURATION TRANSFER,里面新增 HeNB GW的 信息, 其中包括: HeNB ID、 HeNB IP Address, HeNB GW ID、 HeNB GW IP Address, 以及可选的包括用来标识是家庭基站网关还是家庭基站的指示信 息, 然后将该消息发往 MME, 其中目标基站标识为 eNBl的标识。
步骤 107 : MME 在收到步骤 104a 或者步骤 106 返回的 ENB CONFIGURATION TRANSFER消息后,重新使用 MME CONFIGURATION TRANSFER将其里面的内容进行封装 , 然后发送 MME CONFIGURATION TRANSFER到 eNB 1。 该消息中包括: HeNB ID、 HeNB IP Address、 HeNB GW ID, HeNB GW IP Address„
步骤 108: eNBl在收到 MME CONFIGURATION TRANSFER消息后, 解析其中的内容, 根据 HeNB GW的信息以及、 eNB2的信息以及自身的配 置, 对建立 X2直接接口的网元进行选择判断, 即: 判断是选择向家庭基站 网关还是向家庭基站建立直接接口。
步骤 109: eNBl向家庭基站网关或者家庭基站发送 X2建立请求消息。 步骤 110: 目标网元向 eNBl返回 X2建立响应消息, 完成 eNBl和目 标网元的直接接口的建立。 其中, 目标网元为家庭基站网关或者家庭基站。
以上流程中, 发起直接接口建立的网元可以是宏基站或者家庭基站以 及家庭基站网关, 为了描述简单, 在这里不再赘述。 方法实施例 2: 目标侧判断选择建立直接接口的流程。
本方法实施例描述的是由目标侧来选定是向目标家庭基站还是家庭基 站网关建立直接接口并返回相对应的选定的地址信息, 源侧根据返回的选 定的地址信息建立 X2直接接口的情况。 为了描述方便, 我们用 eNBl来表 示源基站、 eNB2来表示目标基站, 其中 eNB 1可以是普通的宏基站也可以 是家庭基站以及家庭基站网关, eNB2通过家庭基站网关 HeNB GW接入 MME。 如图 4所示, 本方法实施例选择建立直接接口建立流程包括以下步 骤:
步骤 201到步骤 203同方法实施例 1中的步骤 101到步骤 103的描述, 在这里不再赘述。
步骤 204: HeNB GW在收到 MME CONFIGURATION TRANSFER消 息后, 判断直接接口建立的网元, 即: 判断是否允许源网元和自己或者是 自己管理的 eNB2建立直接接口。
这里, 如果 HeNB GW仅允许源网元和自己建立直接接口则直接向 MME返回 ENB CONFIGURATION TRANSFER,里面携带自己的用来建立 直接接口的地址信息, 并且可选的指明是家庭基站网关类型的地址信息, 然后转到步骤 207; 否则到步骤 205。
步骤 205: HeNB GW 向 eNB2 发送 MME CONFIGURATION TRANSFER或者其他的消息获取 eNB2的 IP地址。
步骤 206 : eNB2 向家庭基站网关返回 ENB CONFIGURATION TRANSFER消息或者其他消息将自己的 IP地址传递给家庭基站网关。该消 息中包括: HeNB ID、 HeNB IP Address。
步骤 207: 家庭基站网关在收到了 eNB2的地址后, 将 eNB2的 IP 地址通过 ENB CONFIGURATION TRANSFER消息传递至 MME。该消息中 包括: 目标网元 ID、 目标网元 IP Address。 步骤 208: MME在收到 ENB CONFIGURATION TRANSFER消息后, 然后发送 MME CONFIGURATION TRANSFER到 eNBl。 该消息中包括: 目标网元 ID、 目标网元 IP Address。
步骤 209: eNBl在收到 MME CONFIGURATION TRANSFER消息后, 解析其中的内容, 根据该消息里面携带的网源的地址建立直接接口, eNBl 向家庭基站网关或者家庭基站发送 X2建立请求消息。
步骤 210: 目标网元向 eNBl返回 X2建立响应消息, 完成 eNBl和目 标网元的直接接口的建立。 其中, 目标网元为家庭基站网关或者家庭基站。
