- Step 201 After measuring the strong signal of the neighboring eNB cell, the UE in the HeNB cell sends a measurement report to the HeNB, where the measurement report may include PCI, ECGI, TAC, PLMN list, and the like.
- the HeNB After obtaining the ECGI (PLMN ID + cell ID) of the neighboring cell, the HeNB determines that it is a macro cell by using information such as PCI or ECGI or CSG ID, and takes the first 20 bits of its cell ID as its eNB ID; The cell takes all 28 bits of its cell ID as its eNB ID.
- the HeNB After obtaining the eNB ID and TAI (PLMN + TAC) of the neighboring base station, the HeNB needs to initiate a TNL address discovery process to obtain its transport layer address for establishing the X2 connection.
- Step 202 The HeNB sends an eNB configuration transfer message (eNB configuration transfer) to the MME.
- the HeNB uses the HeNB GW as the SI proxy and the MME.
- the SI connection is established, so the eNB configuration transfer message is first sent to the He B GW.
- the message includes the eNB ID and TAI of the source and target base stations, and an indication that the request type is a TL address. If the HeNB is not connected to the HeNB GW, the message is sent directly to the MME without passing through the HeNB GW.

If the X2 GW receives the X2 base station configuration update message in step 208, it sends an X2 base station configuration update acknowledgement or an X2 base station configuration update failure message to the HeNB, where the indication information is carried.

- Step 211 After receiving the indication information, the HeNB may determine, according to the indication information and the local configuration information, whether to establish a direct connection with the eNB. If it is determined that the direct X2 connection is established with the eNB, the X2 setup request message is directly sent to the eNB, where the serving cell, the neighboring cell, and the MME pool information of the HeNB are carried. If it is determined that a direct X2 connection is not established with the eNB, the X2 setup procedure is not initiated.

- Step 309 After obtaining the address of the newly discovered eNB by the HeNB, the X2 GW determines that the SCTP connection or the X2 connection cannot be established with the eNB. For example, the X2 GW fails to establish an SCTP connection or an X2 connection with the eNB, and the X2 GW determines not to initiate an SCTP connection or an X2 connection establishment with the eNB according to the operator policy or the local configuration information.
- the X2 GW may locally store the information of the eNB for subsequent X2 connection type determination. For example, if another HeNB of the X2 GW discovers the eNB and sends an X2 setup request message to the X2 GW, where the eNB ID and/or address of the eNB is carried, the X2 GW may directly reply to the X2 setup failure message, where the indication is carried.

- Step 407 After receiving the eNB configuration transfer message, the MME sends an MME configuration transfer message to the HeNB according to the eNB ID and the TAI of the target base station, where the message includes the indication information and the transport layer address of the eNB for establishing the X2 connection.
- the HeNB establishes an SI connection with the MME through the HeNB GW as the SI proxy, and therefore the MME configuration transfer message is first sent to the HeNB GW.
- Step 408 After receiving the message, the HeNB GW sends the message to the HeNB, where the message includes the indication information and the transport layer address of the eNB for establishing the X2 connection.
- Step 409 After receiving the indication information, the HeNB may follow the indication information and the local configuration information. Determine whether to establish a direct connection with the eNB. If it is determined that the direct X2 connection is established with the eNB, the X2 setup request message is directly sent to the eNB, where the serving cell, the neighboring cell, and the MME pool information of the HeNB are carried. If it is determined that a direct X2 connection is not established with the eNB, the X2 setup procedure is not initiated.
- Step 410 The eNB returns an X2 setup response message to the HeNB, where the eNB carries the serving cell, the neighboring cell, and the MME pool information. At this point, the X2 connection establishment process between the eNB and the HeNB is completed.
- FIG. 5 is a schematic flowchart of Embodiment 4 of a connection establishment method according to the present invention. As shown in FIG. 5, the connection establishment method of this example includes the following steps:
- Step 501 After measuring the strong signal of the neighboring eNB cell, the UE in the HeNB cell sends a measurement report to the HeNB, where the measurement report may include PCI, ECGI, TAC, PLMN list, and the like.
- the HeNB After obtaining the ECGI (PLMN ID + cell ID) of the neighboring cell, the HeNB determines that it is a macro cell by using information such as PCI or ECGI or CSG ID, and takes the first 20 bits of its cell ID as its eNB ID; The cell takes all 28 bits of its cell ID as its eNB ID.
- the HeNB After obtaining the eNB ID and TAI (PLMN + TAC) of the neighboring base station, the HeNB needs to initiate a TNL address discovery process to obtain its transport layer address for establishing the X2 connection.
- Step 502 The HeNB sends an S1 interface eNB configuration transfer message to the MME.
- the HeNB establishes an SI connection with the MME through the HeNB GW as the SI proxy, and therefore the eNB configuration transfer message is first sent to the HeNB GW.
- the message includes the X2 transport layer address of the X2 GW of the HeNB, and the X2 transport layer address of the HeNB.
- the message also includes the eNB ID and TAI of the source and destination base stations, and an indication that the request type is a TNL address. If the HeNB is not connected to the HeNB GW, the message is sent directly to the MME without passing through the HeNB GW. Optionally, the message may further include an X2 connection establishment indication.
- Step 503 After receiving the eNB configuration transfer message, the HeNB GW sends the eNB configuration transfer message to the MME.
- Step 504 After receiving the eNB configuration transfer message, the MME sends an MME configuration transfer message to the eNB.
- the MME may determine the target base station that sends the MME configuration transfer message according to the eNB ID and TAI of the target base station in the eNB configuration transfer message.
- Step 505 After obtaining the address of the X2 GW of the HeNB, the eNB determines that the SC2 connection or the X2 connection cannot be established with the X2 GW, or cannot register with the X2 GW. For example, the SCTP connection or X2 connection establishment or X2 registration of the eNB with the X2 GW fails, and the eNB determines not to initiate an SCTP connection or X2 connection establishment or X2 registration with the X2 GW according to the operator policy or the local configuration information.
- Step 506 The eNB returns an eNB configuration transfer message to the MME.
- the message includes an indication.
- the indication information is used to indicate that the eNB is unable to establish an SCTP connection or an X2 connection with the X2 GW, or cannot register with the X2 GW, or instruct the HeNB to establish a direct X2 connection with the eNB.
- Step 507 After receiving the eNB configuration transfer message, the MME sends an MME configuration transfer message to the HeNB according to the eNB ID and the TAI of the target base station.
- the HeNB establishes an SI connection with the MME through the HeNB GW as the SI proxy, and therefore the MME configuration transfer message is first sent to the HeNB GW.
- Step 508 After receiving the HeNB, the GW sends the message to the HeNB.
- Step 509 the eNB determines that the SC2 connection or the X2 connection cannot be established with the X2 GW, or fails to register with the X2 GW, and determines to establish a direct X2 connection with the HeNB, and directly sends an X2 setup request message to the HeNB, where the serving cell of the eNB is carried. Adjacent cell, MME pool information.
- the message includes an indication. The indication information is used to indicate that the eNB cannot establish an SCTP connection or an X2 connection with the X2 GW, or indicate that the HeNB should establish a direct X2 with the eNB. connection. Step 509 here may be performed before or after step 506.
- Step 510 The HeNB may determine, according to the local configuration information and/or the indication information, whether to accept the direct connection establishment request of the eNB, and if yes, reply the X2 setup response message to the eNB, where the serving cell, the neighboring cell, and the MME pool information of the HeNB are carried. . At this point, the X2 connection establishment process between the eNB and the HeNB is completed. If not, the X2 setup failure message is returned to the eNB.

Description
连接建立方法与装置、 系统、 存储介质 技术领域
本发明涉及连接建立技术, 尤其涉及一种基站之间的连接建立方法与 装置、 系统、 存储介质。 背景技术
家庭基站是一种 '』、型低功率基站 , 主要用于家庭和办公室等小范围室 内场所。 家庭基站通过室内的电缆、 DSL 或光纤等有线接入设备连接到移 动运营商核心网, 为特定用户提供基于无线移动通信网络的接入业务。 是 对现有网络部署的有效补充, 能有效提高室内语音和高速数据业务覆盖。 具有很多优点, 如低成本、 低功率、 接入简单、 即插即用、 节省回传、 与 现有终端兼容, 提高网络覆盖等。
第三代伙伴组织计划 ( 3GPP, Third Generation Partnership Project )标 准组织定义的长期演进(LTE, Long Term Evolution ) 系统中家庭基站被称 为 HeNB ( Home eNB )。 HeNB所支持的功能与 eNB基本一致, HeNB与演 进分组核心 (EPC, Evolved Packet Core ) 网之间的进程和 eNB与 EPC之 间基本一致。 由于 HeNB 的布署通常没有经过移动运营商的网络规划、 覆 盖范围小且数量众多。 为了更方便地管理并为了支持更多数量的 HeNB,在 E-UTRAN ( Evolved UTRAN ) 架构下, 在 HeNB与 EPC的 S1连接之间引 入一个新的网元家庭基站网关(HeNB GW, Home eNB Gateway )。 HeNB 可通过 HeNB GW 作为 SI 代理连接移动管理实体 ( MME , Mobility Management Entity )。 在 LTE RIO版本中, HeNB之间仅存在 X2直接接口 (即不通过其它节点如代理节点建立的 X2接口), 可用于负荷均衡, 切换 优化, 信息交互等, 而宏基站 eNB和家庭基站 HeNB间不支持 X2接口。
而在 LTE R11中,引入新的功能实体 X2网关(X2 GW, X2 GW与 HeNB GW类似, 为可选部署, eNB和 HeNB之间、 HeNB和 HeNB之间可通过 X2 GW建立代理的 X2接口,或者不通过 X2 GW建立直接的 X2接口。 HeNB 只能与一个 X2 GW连接。 HeNB上电后可通过 HeMS获得其 X2 GW和 HeNB GW的地址。 HeNB获得 X2 GW地址后可向该 X2 GW注册, 用于 X2 GW获取该 HeNB的 eNB ID和用于建立 X2连接的 IP地址信息。当 HeNB 发现新的相邻 (H)e B小区后且想要与该相邻基站建立 X2连接, 可直接向 所连接的 X2 GW发送 X2建立请求消息,其中携带目标 (H)e B的 eNB ID , X2 GW接收到后若本地已经保存该目标 (H)eNB的 eNB ID及用于建立 X2 连接的地址映射信息 , 则可根据该消息中 eNB ID将该 X2建立请求消息路 由至目标 (H)e B。若 X2 GW本地尚未保存该目标 eNB的 eNB ID及用于建 立 X2连接的地址映射信息,则 HeNB与该目标 eNB间的 X2连接建立过程 无法顺利完成。 可通过 HeNB发起的 TNL过程获得 eNB地址后发送给 X2 GW, 由 X2 GW发起与目标 eNB的 SCTP或 X2连接建立来解决。 或通过 HeNB在其发起的 T L过程中将 X2 GW地址发送给 eNB , 由 eNB发起向 X2 GW的注册或 X2连接建立来解决。 但是若 eNB与 X2 GW间注册或连 接建立失败, 则该 HeNB与新发现的相邻 eNB间的 X2连接建立无法顺利 进行。 发明内容

具体实施方式
为使本发明的目的、 技术方案和有点更加清楚明白, 下文中将结合附 图对本发明的实施例进行详细说明。 需要说明的是, 在不沖突的情况下, 本申请中的实施例及实施例中的特征可以相互任意组合。
图 1为 X2网关部署情况下的家庭基站网络架构示意图, 如图 1所示, HeNB可通过 HeNB GW作为 S 1代理连接 MME ,在 LTE l 1版本中, HeNB 还可通过 X2网关( X2 GW )作为 X2代理连接相邻基站(家庭基站或宏基 站)。 其中 HeNB GW和 X2 GW均为可选部署。 如图 1所示, eNB 1通过 X2 GW与 HeNB2和 HeNB3建立代理的 X2接口, HeNB2和 He B3间通 过 X2 GW建立代理的 X2接口。 e B l还可以与 HeNB l建立直接的 X2接 口。 需要注意的是, 本发明的技术方案不局限于 LTE HeNB系统, 还可适 用于 3G HNB系统。
方法实施例一
本实施例描述的是 HeNB通过 X2接口消息获得指示信息并确定发起直 接 X2连接建立的方法。图 2为根据本发明的连接建立方法实施例一的流程 示意图, 如图 2所示, 本示例的连接建立方法包括以下步骤:
步骤 201 , HeNB小区下的 UE测量到相邻 eNB小区的较强信号后, 发 送测量艮告给 HeNB , 其中测量报告中可包括 PCI, ECGI, TAC, PLMN list 等。 HeNB获得该相邻小区的 ECGI ( PLMN ID + cell ID ) 后, 通过 PCI或 ECGI或 CSG ID等信息判断其为宏小区 , 则取其 cell ID的前 20比特作为 其 eNB ID;若为家庭基站小区,则取其 cell ID的全部 28比特作为其 eNB ID。 HeNB获得相邻基站的 eNB ID和 TAI ( PLMN + TAC )后, 需要发起 TNL 地址发现过程以获得其用于建立 X2连接的传输层地址。
步骤 202 , HeNB发送 S1接口基站配置传输消息(eNB configuration transfer )给 MME,该实施例中 HeNB通过 HeNB GW做为 SI代理与 MME
建立 SI连接,因此该 eNB configuration transfer消息首先发送至 He B GW。 该消息中包含源和目标基站的 eNB ID和 TAI , 和请求类型为 T L地址的 指示。 若 HeNB不与 HeNB GW相连, 则该消息不经过 HeNB GW, 直接发 送至 MME。
步骤 203 , HeNB GW接收到 eNB configuration transfer消息后,将其发 送至 ΜΜΕ。
步骤 204 , MME接收 eNB configuration transfer消息后, 发送 MME configuration transfer 消息给 eNB。 其中 MME可才艮据 eNB configuration transfer消息中目标基站的 eNB ID和 TAI确定其发送 MME configuration transfer消息的目标基站。
步骤 205 , eNB接收到 MME configuration transfer消息后, 回复 eNB configuration transfer消息给 MME ,该消息中包含 eNB的用于建立 X2连接 的传输层地址。
步骤 206 , MME接收到 eNB configuration transfer消息后, 根据其中的 目标基站的 eNB ID和 TAI发送 MME configuration transfer消息给 HeNB , 该消息中包含 eNB 的用于建立 X2 连接的传输层地址。 由于该实施例中 HeNB通过 HeNB GW做为 SI代理与 MME建立 SI连接, 因此, 该 MME configuration transfer消息首先发送至 HeNB GW。
步骤 207 , HeNB GW接收到后将该消息发送到 HeNB , 该消息中包含 eNB的用于建立 X2连接的传输层地址。
步骤 208 , HeNB通过 T L地址发现过程获得 eNB的地址之后, 发送 X2建立请求消息给 X2 GW, 该消息中携带其通过 T L地址发现过程获得 的 eNB的 X2传输层地址, 以触发 X2 GW与 eNB的 SCTP连接或 X2连接 建立, 该消息中还可以包含 HeNB的 X2接口应用层配置信息, 包括 HeNB 的 eNB ID, HeNB下的服务小区信息, 服务小区的相邻小区信息, 所连接
的 MME池信息。
或者, HeNB通过 TNL地址发现过程获得 e B的地址之后, 发送 X2 基站配置更新消息给 X2 GW,该消息中携带其通过 T L地址发现过程获得 的 eNB的 X2传输层地址, 以触发 X2 GW与 eNB的 SCTP连接或 X2连接 建立。
