一种建立 X2接口的方法和基站以及信息处理方法和网关 Method and base station for establishing X2 interface, and information processing method and gateway

技术领域 Technical field

本发明涉及无线通讯技术领域，尤其涉及一种建立 X2 (基站与基站）接口的方法和基站装置以及信息处理方法和网关装置。 The present invention relates to the field of wireless communication technologies, and in particular, to a method and a base station apparatus for establishing an X2 (base station and base station) interface, and an information processing method and a gateway apparatus.

背景技术 Background technique

家庭基站是一种小型的低功率基站，作为私人用户的专用资源被部署在家庭、团体、公司或者学校等私人场所，通过电缆、 DSL( Digital Subscriber Line, 数字用户线路）或者光纤等有线接入设备连接到运营商的核心网。家庭基站的主要作用是给用户提供更高的业务速率，并降低使用高速率业务所需要的花费，同时弥补已有分布式蜂窝无线通讯***的覆盖不足。家庭基站的优点包括：低成本、使用方便（即插即用）、低输出功率、节省了运营商架设和维护基站的费用、解决室内覆盖优化等。 The home base station is a small, low-power base station that is deployed as a dedicated resource for private users in private places such as homes, groups, companies, or schools, and is connected by cable, DSL (Digital Subscriber Line), or fiber-optic cable. The device is connected to the carrier's core network. The main role of the home base station is to provide users with higher service rates and to reduce the cost of using high-rate services, while at the same time making up for the inadequate coverage of existing distributed cellular wireless communication systems. The advantages of the home base station include: low cost, easy to use (plug and play), low output power, saving the cost of setting up and maintaining the base station, and solving indoor coverage optimization.

在长期演进（Long Term Evolution, 简称 LTE )***中，演进的家庭基站被称为 HeNB ( Home Evolved NodeB ) 。图 1是相关技术中 HeNB的网络架构示意图。 HeNB下的终端（User Equipment, 简称 UE )是基于相关的空口协议接入演进的家庭基站接入网（ Home Evolved NodeB Access Network, 简称 HeNBAN ) 。 HeNB AN是由 HeNB和演进的家庭基站网关（ Home Evolved NodeB Gateway , 简称 HeNB GW )组成。 HeNB所支持的功能与 eNB基本一致。一个 HeNB下仅连接一个小区。 HeNB GW是可选的网元。 HeNB GW的主要功能为：中继 UE相关的 S1消息，终结非 UE相关的 S1消息，在附着过程中替 UE选择 MME等。 HeNB可以通过 S1接口直接连接到演进的分组核心 ( Evolved Packet Core, 简称 EPC ) ，其中 HeNB通过 SI - U接口连接到服务网关（ Serving Gateway, 简称 S - GW ) , HeNB通过 SI - MME接口连接到移动管理实体（Mobility Management Entity, 简称 MME ) 。 HeNB也可以通过 HeNB GW连接到 EPC, 其中 SI - U接口可以终止在 HeNB GW, 或者终止在 EPC, SI - MME接口经过 HeNB GW到 EPC。 EPC网元包括 MME 和 S - GW。 MME承担着承载管理、移动性管理等相关功能。 S - GW承担着用户面的数据路由等功能。此外，图 1中的演进的家庭基站管理***（HeNB Management System, 简称 HeMS )对 HeNB进行维护和管理，根据运营商的要求配置和控制 HeNB , 其中最主要的是为 HeNB实现配置功能，配置的内容包括位置信息的核实， HeNB的参数，核心网的参数，无线接入网（Radio Access Network, 简称 RAN ) 的参数以及无线频率（Radio Frequency, 简称 RF ) 的参数。安全网关（ Security Gateway, 简称 SeGW ) 支持网络中的安全相关的功能。 In the Long Term Evolution (LTE) system, the evolved home base station is called HeNB (Home Evolved NodeB). FIG. 1 is a schematic diagram of a network architecture of a HeNB in the related art. The User Equipment (UE) is a Home Evolved NodeB Access Network (HeNBAN) that is based on the associated air interface protocol. The HeNB AN is composed of a HeNB and an Evolved NodeB Gateway (HeNB GW for short). The functions supported by the HeNB are basically the same as those of the eNB. Only one cell is connected under one HeNB. The HeNB GW is an optional network element. The main functions of the HeNB GW are: relaying the S1 message related to the UE, terminating the non-UE related S1 message, and selecting the MME for the UE during the attaching process. The HeNB can be directly connected to the Evolved Packet Core (EPC) through the S1 interface, where the HeNB is connected to the Serving Gateway (S-GW) through the SI-U interface, and the HeNB is connected to the S-GW through the SI-MME interface. Mobility Management Entity (MME). The HeNB may also connect to the EPC through the HeNB GW, where the SI-U interface may terminate at the HeNB GW, or terminate at the EPC, and the SI-MME interface passes through the HeNB GW to the EPC. The EPC network element includes an MME and an S-GW. The MME is responsible for related functions such as bearer management and mobility management. S-GW bears User data routing and other functions. In addition, the evolved HeNB Management System (HMS) in FIG. 1 maintains and manages the HeNB, and configures and controls the HeNB according to the requirements of the operator. The most important one is to implement configuration functions for the HeNB. The content includes verification of location information, parameters of the HeNB, parameters of the core network, parameters of the Radio Access Network (RAN), and parameters of the Radio Frequency (RF). The Security Gateway (SeGW) supports security-related functions in the network.

第三代合作伙伴计划（3GPP, 3^rd Generation Partnership Project )在超高速传送规范 Release 10的时候标准化了 HeNB之间用于切换目的的直接 X2 接口，如图 1。 3GPP在 Release 1 1的时候标准化了 eNB和 HeNB之间的用于切换目的的直接 X2接口。由于 HeNB的数量众多，为了减少 eNB需要处理的流控制传输协议 ( SCTP, Stream Control Transmission Protocol )连接的数量， 3GPP将在 Release 12的时候标准化新的功能实体，即 X2网关（ X2 Gateway, 简称 X2 GW ) , 从而来支持 eNB和 HeNB之间或 HeNB和 HeNB之间的通过 X2 GW的 X2连接。将在 Release 12中标准化的 X2 GW,类似于当前标准中的 SI GW (图 1中的 HeNB GW当前仅仅只有 S1接口的代理功能，又称为 SI GW ) , 是可选部署的。 eNB和 HeNB之间、 HeNB和 HeNB之间可以建立直接的 X2接口，也可以通过 X2 GW建立代理的 X2接口。但是 eNB和 HeNB对之间、 HeNB和 HeNB对之间不能同时建立直接的 X2接口和通过 X2 GW建立代理的 X2接口。也即， eNB和 HeNB对之间、 HeNB和 HeNB 对之间要不建立直接的 X2接口，要不建立通过 X2 GW代理的 X2接口。 Third Generation Partnership Project ^{(3GPP, 3 rd Generation Partnership Project} ) ultra high-speed transmission at the time of Release 10 specifications standardized direct X2 interface between the HeNB for switching purposes, as shown. The 3GPP standardizes the direct X2 interface between the eNB and the HeNB for handover purposes at Release 11. Due to the large number of HeNBs, in order to reduce the number of Stream Control Transmission Protocol (SCTP) connections that the eNB needs to process, 3GPP will standardize new functional entities in Release 12, namely X2 Gateway (X2 Gateway, X2 for short). GW ) to support the X2 connection through the X2 GW between the eNB and the HeNB or between the HeNB and the HeNB. The X2 GW to be standardized in Release 12 is similar to the SI GW in the current standard (the HeNB GW in Figure 1 currently only has the proxy function of the S1 interface, also known as the SI GW), which is optionally deployed. A direct X2 interface can be established between the eNB and the HeNB, between the HeNB and the HeNB, and the X2 interface of the proxy can also be established through the X2 GW. However, the direct X2 interface and the X2 interface that establishes the proxy through the X2 GW cannot be established between the eNB and the HeNB, and between the HeNB and the HeNB. That is, a direct X2 interface is not established between the eNB and the HeNB pair, between the HeNB and the HeNB pair, and the X2 interface through the X2 GW proxy is not established.

当前， 3GPP正在讨论两种设计的 X2 GW方案，即 Ml proxy (完全代理）和 X2 routing proxy ( X2路由代理），并将在这两种方案中选择一种作为标准化 X2 GW的最终方案。在 full proxy方案中， X2建立是逐跳（ hop by hop ) 的。 X2建立被完全终止、解读、存储在 X2 GW中。在 X2建立过程中，要建立两段 X2连接，一段建立在 eNB和 X2 GW之间或 HeNB和 X2 GW之间 , 另一段建立在 X2 GW和 HeNB之间，并且这两段 X2连接都是被 X2 GW独立管理的。因此，在 hop by hop的 X2建立中，可能会导致意图建立直接 X2 接口的 eNB和 HeNB对之间或者 HeNB和 HeNB对之间，在还未建立直接 X2接口之前就已经通过 X2 GW建立了代理的 X2连接的问题。下面将对所述问题进行描述。 Currently, 3GPP is discussing two designed X2 GW schemes, namely Ml proxy (full proxy) and X2 routing proxy (X2 routing proxy), and will choose one of the two schemes as the final scheme for standardizing X2 GW. In the full proxy scheme, the X2 build is hop by hop. The X2 build is completely terminated, interpreted, and stored in the X2 GW. In the X2 establishment process, two X2 connections are established, one segment is established between the eNB and the X2 GW or between the HeNB and the X2 GW, and the other segment is established between the X2 GW and the HeNB, and the two X2 connections are both X2. GW is managed independently. Therefore, in the X2 establishment of hop by hop, it may result in the intention of establishing a direct X2 interface between the eNB and the HeNB pair or between the HeNB and the HeNB pair, The X2 interface has previously established the X2 connection of the proxy through the X2 GW. The problem will be described below.

如图 2所示 , eNBl和 HeNB2之间意图通过 X2 GW建立代理的 X2连接， eNBl和 HeNB3之间意图通过 X2 GW建立代理的 X2连接，但是 HeNB2和 HeNB3之间意图建立直接的 X2连接。由于 HeNB2是连接在 X2 GW上的，因此 HeMS便会在 HeNB2上电后，给 HeNB2配置 X2 GW的 IP地址。 HeNB2 获取到 X2 GW的 IP地址后，便会与 X2 GW建立 X2连接。当 eNBl和 X2 GW 之间的 X2接口建立后 , eNBl和 HeNB2之间的通过 X2 GW的代理 X2连接则被建立完成。同样地，由于 HeNB3是连接在 X2 GW上的，因此 HeMS便会在 HeNB3上电后，给 HeNB3配置 X2 GW的 IP地址。 HeNB3获取到 X2 GW 的 IP地址后，便会与 X2 GW建立 X2连接。此时，由于 X2 GW根据其存储的信息判断出自己和 eNBl之间已经存在 X2接口， X2 GW则发送 eNB配置更新（ eNB Configuration Update )消息给 HeNB3。该 eNB配置更新消息的添加的服务小区 Served Cells To Add )信元中包括了 X2 GW中存储的 eNBl 的服务小区信息。同时，因为 X2 GW根据其存储的信息判断出自己和 HeNB2 之间已经存在 X2接口，则 X2 GW在发送给 HeNB3的 eNB配置更新消息的 Served Cells To ¾信元中也会将 HeNB2的服务小区信息通知给 HeNB3。 HeNB3根据接收到的 eNB配置更新消息中的 Served Cells To Add信元，则可以知道 Χ2 GW和 eNB 1之间是有 X2接口的、 X2 GW和 HeNB2之间也是有 X2接口的。继而 HeNB3则会认为自身和 eNBl之间的通过 X2 GW的代理 X2连接是可用的，同时， HeNB3也会认为自身和 HeNB2之间的通过 X2 GW 的代理 X2连接是可用的。由于 HeNB2和 HeNB3之间不能同时建立直接的 X2接口和通过 X2 GW建立代理的 X2接口。则 HeNB2和 HeNB3之间不再会建立直接 X2连接。然而，事实上， HeNB2和 HeNB3之间意图是建立直接的 X2连接的。 As shown in FIG. 2, the X2 connection between the eNB1 and the HeNB2 is intended to be established by the X2 GW. The eNB1 and the HeNB3 intend to establish a proxy X2 connection through the X2 GW, but the H2 and the HeNB3 intend to establish a direct X2 connection. Since HeNB2 is connected to the X2 GW, the HeMS will configure the X2 GW IP address for HeNB2 after HeNB2 is powered on. After HeNB2 obtains the IP address of the X2 GW, it establishes an X2 connection with the X2 GW. After the X2 interface between the eNB1 and the X2 GW is established, the proxy X2 connection between the eNB1 and the HeNB2 through the X2 GW is established. Similarly, since HeNB3 is connected to the X2 GW, the HeMS will configure the X2 GW IP address for HeNB3 after HeNB3 is powered on. After HeNB3 obtains the IP address of the X2 GW, it establishes an X2 connection with the X2 GW. At this time, the X2 GW sends an eNB Configuration Update message to the HeNB 3 because the X2 GW determines that the X2 interface already exists between itself and the eNB1 according to the information stored therein. The added serving cell Served Cells To Add of the eNB configuration update message includes the serving cell information of the eNB1 stored in the X2 GW. At the same time, because the X2 GW determines that the X2 interface exists between itself and HeNB2 according to the information stored by the X2 GW, the X2 GW also sets the serving cell information of the HeNB2 in the Served Cells To3 cell of the eNB configuration update message sent to the HeNB3. Notify to HeNB3. Based on the Served Cells To Add cell in the received eNB configuration update message, the HeNB3 can know that there is an X2 interface between the GW2 GW and the eNB 1, and an X2 interface between the X2 GW and the HeNB2. Then HeNB3 considers that the proxy X2 connection between itself and eNB1 through the X2 GW is available, and HeNB3 also considers that the proxy X2 connection through X2 GW between itself and HeNB2 is available. Since HeNB2 and HeNB3 cannot simultaneously establish a direct X2 interface and an X2 interface that establishes a proxy through the X2 GW. Then a direct X2 connection is no longer established between HeNB2 and HeNB3. However, in fact, the intention between HeNB2 and HeNB3 is to establish a direct X2 connection.

如图 3所示 , HeNB2和 HeNB3意图通过 X2 GW建立代理的 X2连接， eNBl和 HeNB2意图通过 X2 GW建立代理的 X2连接，但是 eNBl和 HeNB3 意图建立直接的 X2连接。由于 HeNB2是连接在 X2 GW上的，因此 HeMS 便会在 HeNB2上电后，给 HeNB2配置 X2 GW的 IP地址。 HeNB2获取到 X2 GW的 IP地址后，便会与 X2 GW建立 X2连接。当 eNBl和 X2 GW之间的 X2接口建立后 , eNBl和 HeNB2之间的通过 X2 GW的代理 X2连接则被建立完成。同样地，由于 HeNB3是连接在 X2 GW上的，因此 HeMS便会在 HeNB3上电后，给 HeNB3配置 X2 GW的 IP地址。 HeNB3获取到 X2 GW的 IP地址后，便会与 X2 GW建立 X2连接。此时，由于 X2 GW根据其存储的信息判断出自己和 HeNB2之间已经存在 X2接口， X2 GW则发送 eNB配置更新消息给 HeNB3。该 eNB配置更新消息的 Served Cells To Add信元中包括了 HeNB2的服务小区信息。同时，因为 X2 GW根据其存储的信息判断出自己和 eNBl之间已经存在 X2接口，则 X2 GW在发送给 HeNB3的 eNB配置更新消息的 Served Cells To Add信元中也会将其存储的 eNB 1的服务小区信息通知给 HeNB3。 HeNB3根据接收到的 eNB配置更新消息中的 Served Cells To Add信元 ,则可以知道 Χ2 GW和 HeNB2之间是有 X2接口的、 X2 GW和 eNB 1 之间也是有 X2接口的。继而 HeNB3则会认为自身和 HeNB2之间的通过 X2 GW的代理 X2连接是可用的，同时， HeNB3也会认为自身和 eNBl之间的通过 X2 GW的代理 X2连接是可用的。由于 eNB 1和 HeNB3之间不能同时建立直接的 X2接口和通过 X2 GW建立代理的 X2接口。则 eNBl和 HeNB3之间不再会建立直接 X2连接。然而，事实上， eNBl和 HeNB3之间意图是建立直接的 X2连接的。发明内容 As shown in FIG. 3, HeNB2 and HeNB3 intend to establish a proxy X2 connection through the X2 GW, and eNB1 and HeNB2 intend to establish a proxy X2 connection through the X2 GW, but eNB1 and HeNB3 intend to establish a direct X2 connection. Since HeNB2 is connected to the X2 GW, the HeMS will configure the X2 GW's IP address for HeNB2 after HeNB2 is powered on. HeNB2 gets After the IP address of the X2 GW, an X2 connection is established with the X2 GW. After the X2 interface between the eNB1 and the X2 GW is established, the proxy X2 connection between the eNB1 and the HeNB2 through the X2 GW is established. Similarly, since the HeNB 3 is connected to the X2 GW, the HeMS configures the H2 address of the X2 GW for the HeNB 3 after the HeNB 3 is powered on. After HeNB3 obtains the IP address of the X2 GW, it establishes an X2 connection with the X2 GW. At this time, the X2 GW sends an eNB configuration update message to the HeNB 3 because the X2 GW determines that the X2 interface already exists between itself and the HeNB 2 according to the information stored therein. The Served Cells To Add cell of the eNB configuration update message includes the serving cell information of the HeNB2. At the same time, because the X2 GW determines that the X2 interface exists between itself and the eNB1 according to the information stored by the X2 GW, the X2 GW also stores the eNB 1 in the Served Cells To Add cell of the eNB configuration update message sent to the HeNB3. The serving cell information is notified to HeNB3. According to the Served Cells To Add cell in the received eNB configuration update message, the HeNB3 can know that there is an X2 interface between the GW2 GW and the HeNB2, and there is also an X2 interface between the X2 GW and the eNB1. HeNB3 then considers that the proxy X2 connection between itself and HeNB2 through the X2 GW is available, and HeNB3 also considers that the proxy X2 connection between itself and eNB1 through the X2 GW is available. Since the direct X2 interface cannot be established between eNB 1 and HeNB 3 and the X2 interface of the proxy is established through the X2 GW. Then a direct X2 connection is no longer established between eNB1 and HeNB3. However, in fact, the intention between eNB1 and HeNB3 is to establish a direct X2 connection. Summary of the invention

方式二：以 HeNB为粒度，配置与该 HeNB建立直接 X2接口的所有 eNB 和 HeNB列表，以及与该 HeNB建立通过 X2 GW代理的 X2接口的所有 eNB 和 HeNB列表。同时，以 eNB为粒度，配置与该 eNB建立直接 X2接口的所有 HeNB列表和与该 eNB建立通过 X2 GW代理的 X2接口的所有 HeNB列表。 Manner 2: Configuring a list of all eNBs and HeNBs that establish a direct X2 interface with the HeNB and a list of all eNBs and HeNBs that establish an X2 interface that is proxied by the X2 GW with the HeNB. At the same time, with the eNB as the granularity, all HeNB lists that establish a direct X2 interface with the eNB and all HeNB lists that establish X2 interfaces through the X2 GW proxy with the eNB are configured.

方式三：以 HeNB为粒度，配置与该 HeNB建立直接 X2接口的所有 eNB 和 HeNB列表，并且以 eNB为粒度，配置与该 eNB建立直接 X2接口的所有 HeNB列表，默认其余不在列表中的 eNB和 HeNB对之间以及 HeNB和 HeNB 对之间需要建立通过 X2 GW代理的 X2接口。或者，仅仅以 HeNB为粒度，配置与该 HeNB建立直接 X2接口的所有 eNB和 HeNB列表，默认其余不在列表中的 eNB和 HeNB对之间以及 HeNB和 HeNB对之间需要建立通过 X2 GW代理的 X2接口。 Manner 3: Configuring a list of all eNBs and HeNBs that establish a direct X2 interface with the HeNB, and configuring all HeNBs that establish a direct X2 interface with the eNB, with the eNB as the granularity, and the rest of the eNBs that are not in the list. An X2 interface through the X2 GW proxy needs to be established between the HeNB pairs and between the HeNB and HeNB pairs. Or, only the HeNB is granular, All eNBs and HeNB lists that establish a direct X2 interface with the HeNB are configured. By default, the remaining X2 interfaces that are not proxyed by the X2 GW need to be established between the eNB and the HeNB pair in the list and between the HeNB and the HeNB pair.

方式四：以 HeNB为粒度，配置与该 HeNB建立通过 X2 GW代理 X2接口的所有 eNB和 HeNB列表，并且以 eNB为粒度，配置与该 eNB建立通过 X2 GW代理 X2接口的所有 HeNB列表，默认其余不在列表中的 eNB和 HeNB 对之间以及 HeNB和 HeNB对之间需要建立直接的 X2接口。或者，仅仅以 HeNB为粒度 ,配置与该 HeNB建立通过 X2 GW代理 X2接口的所有 eNB和 HeNB列表，默认其余不在列表中的 eNB和 HeNB对之间以及 HeNB和 HeNB 对之间需要建立直接的 X2接口。 Manner 4: Configuring, by the HeNB, all the eNBs and HeNBs that are connected to the HeNB through the X2 GW proxy X2 interface, and configuring the HeNB to establish a list of all HeNBs through the X2 GW proxy X2 interface with the eNB as the granularity.

OAM给 X2 GW配置 eNB和 HeNB对之间以及 HeNB和 HeNB对之间的 X2连接方式不仅局限于上述提及的方式。 The OAM configures the X2 GW for the X2 connection between the eNB and the HeNB pair and between the HeNB and the HeNB pair is not limited to the above-mentioned manner.

基于 OAM在 X2 GW处配置的 eNB和 HeNB对之间以及 HeNB和 HeNB 对之间的 X2连接方式。 X2网关可从 OAM的配置中获知任意一对基站之间的 X2连接方式信息， X2 GW向任意基站发送消息时，利用所述消息中携带的信息向该基站表明该基站与其他一个或多个基站对之间的 X2 连接方式信息。 X2 GW发送的消息包括 NB配置更新消息。 The X2 connection mode between the eNB and the HeNB pair and the HeNB and HeNB pair configured based on the OAM at the X2 GW. The X2 gateway can learn the X2 connection mode information between any pair of base stations from the configuration of the OAM. When the X2 GW sends a message to any base station, the X2 GW indicates to the base station the base station and one or more other ones by using the information carried in the message. X2 connection mode information between base station pairs. The message sent by the X2 GW includes an NB configuration update message.

例如， X2 GW判断当任意基站 M和其他一个或多个基站之间需要建立直接的 X2连接，那么 X2 GW可不在 eNB配置更新消息的添加的服务小区 ( Served Cells To Add )信元中包括该其他一个或多个基站的服务小区信息。另一种可行的方式是： X2 GW除了仍在 eNB配置更新消息的 Served Cells To ί信元中包括一个或多个基站的服务小区信息，还在该 eNB配置更新消息中将基站 M与一个或多个基站的 X2连接方式通过指示标识通知给基站 M。 For example, the X2 GW determines that when a direct X2 connection needs to be established between any base station M and one or more other base stations, the X2 GW may not include the Served Cells To Add cell in the eNB configuration update message. Serving cell information of one or more other base stations. Another possible way is: the X2 GW includes the serving cell information of one or more base stations in the Served Cells To ί cells of the eNB configuration update message, and also bases the base station M with one or The X2 connection mode of the plurality of base stations is notified to the base station M by the indication identifier.

上述基站 M可以为 HeNB或 eNB , 其他基站也可以是 HeNB或 eNB ,但一对配置了 X2连接关系的基站中，至少有一个基站为 HeNB。 The base station M may be an HeNB or an eNB, and the other base stations may be HeNBs or eNBs. However, at least one of the base stations in which the X2 connection relationship is configured is the HeNB.

本实施例描述的场景是： eNBl 建立直接 SI连接到 MME, HeNB2通过 HeNB GW建立代理的 S1连接到 MME, HeNB3建立直接 S1连接到 MME, eNBl和 HeNB2之间需要通过 X2 GW建立代理的 X2连接， eNBl和 HeNB3 之间需要通过 X2 GW建立代理的 X2连接，但是 HeNB2和 HeNB3之间需要建立直接的 X2连接，如图 2所示。 The scenario described in this embodiment is: eNB1 establishes a direct SI connection to the MME, HeNB2 establishes a proxy S1 connection to the MME through the HeNB GW, HeNB3 establishes a direct S1 connection to the MME, and an X2 connection needs to be established between the eNB1 and the HeNB2 through the X2 GW. The X2 connection of the proxy needs to be established between the eNB1 and the HeNB3 through the X2 GW, but needs between the HeNB2 and the HeNB3.

如图 7所示，本实施例的具体流程主要包括如下步骤： As shown in FIG. 7, the specific process of this embodiment mainly includes the following steps:

步骤 401： HeNB2上电后与 HeMS交互， HeMS验证 HeNB2后为该 HeNB2 配置参数。因为 HeNB2是连接到 X2 GW的，因此 HeMS给 HeNB2配置 X2 GW的 IP地址。传输网络层（ Transport Network Layer, 简称 TNL )地址为 IP 地址和端口号（port number ) 的组合。由于用于 X2消息传输的 SCTP层的 TNL地址的端口号固定为 36422,因此 HeMS给 HeNB2配置 X2 GW的 IP地址就等于 HeMS给 HeNB2配置 X2 GW的 TNL地址。 HeNB2根据 X2 GW的 TNL地址，与 X2 GW建立用于 X2消息传输的 SCTP连接。 Step 401: After HeNB2 is powered on, it interacts with the HeMS, and the HeMS verifies the HeNB2 and configures parameters for the HeNB2. Since HeNB2 is connected to the X2 GW, the HeMS configures the X2 GW's IP address for HeNB2. The Transport Network Layer (TNL) address is a combination of an IP address and a port number. Since the port number of the TNL address of the SCTP layer for X2 message transmission is fixed to 36422, the HeMS configures the X2 GW IP address for HeNB2 to be equal to the HeMS to configure the X2 GW TNL address for HeNB2. HeNB2 establishes an SCTP connection for X2 message transmission with the X2 GW according to the TNL address of the X2 GW.

步骤 402: HeNB2发送 X2建立请求（ X2 SETUP REQUEST )消息到 X2 GW。 X2建立请求消息中包括了 HeNB2的全局演进节点 B 的标识（Global eNB ID ) HeNB2 ID、 HeNB2的服务小区信息、服务小区的相邻小区信息。 X2 GW在接收到 X2建立请求消息后 ,可以保存 HeNB2 ID和 HeNB2的用于 X2消息传输的 SCTP层的 IP地址（或 TNL地址 ) 的匹配关系。 Step 402: HeNB2 sends an X2 SETUP REQUEST message to the X2 GW. The X2 setup request message includes the identifier (Global eNB ID) of the global evolved Node B of the HeNB2, the HeNB2 ID, the serving cell information of the HeNB2, and the neighbor cell information of the serving cell. After receiving the X2 setup request message, the X2 GW may save the matching relationship between the HeNB2 ID and the IP address (or TNL address) of the SCTP layer of the HeNB2 for the X2 message transmission.

步骤 403: X2 GW回复 X2建立响应（ X2 SETUP RESPONSE ) 消息给 HeNB2。 Step 403: The X2 GW replies to the X2 SETUP RESPONSE message to HeNB2.

步骤 404: 当 eNBl发现相邻的 HeNB2的服务小区，并通过自动邻居关系（ Automatic Neighbor Relation,简称 ANR )获取 HeNB2的 PCI( Physical Cell ID , 物理小区标识）、 ECGI (演进通用陆地无线接入网小区全球标识 ( E-UTRAN Cell Global Identifier ) 、 TAC(Tracking Area Code, 跟踪区域码）、一个或者多个 PLMN ( Public Land Mobile Network,公共陆地移动网络） ID、 CSG ( Closed Subscriber Group, 闭合用户组） ID。源 eNBl准备发起 TNL 地址发现过程来获取目标 HeNB2的用于 X2消息传输的 SCTP层的 TNL地址。 Step 404: When the eNB1 finds the serving cell of the neighboring HeNB2, and acquires the PCI (Physical Cell ID) of the HeNB2, and the ECGI (Evolved Universal Terrestrial Radio Access Network) through the Automatic Neighbor Relation (ANR) E-UTRAN Cell Global Identifier, TAC (Tracking Area Code), one or more PLMN (Public Land Mobile Network) ID, CSG (Closed Subscriber Group) ID. The source eNB1 is ready to initiate a TNL address discovery procedure to obtain the TNL address of the SCTP layer for the X2 message transmission of the target HeNB2.

步骤 405 : 源 eNBl 发送 eNB 配置传输（eNB CONFIGURATION Step 405: The source eNB1 sends an eNB configuration transmission (eNB CONFIGURATION

TRANSFER ) 消息到 MME。 eNB配置传输消息包括了源 eNBl的 eNBl ID、源 eNBl的艮踪区域标识（Tracking Area Identifier, 简称 TAI ) TAI1、目标 HeNB2的 HeNB2 ID、目标 HeNB2的 TAI2。 eNB配置传输消息中也可以携带源 eNBl的用于 X2消息传输的 SCTP层的 TNL地址。 TRANSFER) Message to the MME.

The eNB can also carry the transmission message. The TNL address of the SCTP layer for the X2 message transmission with the source eNB1.

步骤 406: MME在接收到源 eNBl发送的 eNB配置传输消息后，可根据 eNB 配置传输消息中包含的 TAI2 , 发送 MME 配置传输（ MME CONFIGURATION TRANSFER ) 消息到正确的 HeNB GW。 MME配置传输消息包括了 eNBl ID、 TAI1、 HeNB2 ID、 TAI2。 eNB配置传输消息中也可以携带源 eNBl的用于 X2消息传输的 SCTP层的 TNL地址。 Step 406: After receiving the eNB configuration transmission message sent by the source eNB1, the MME may send the MME CONFIGURATION TRANSFER message to the correct HeNB GW according to the TAI2 included in the eNB configuration transmission message. The MME configuration transmission message includes an eNB1 ID, a TAI1, a HeNB2 ID, and a TAI2. The eNB configuration transmission message may also carry the TNL address of the SCTP layer of the source eNB1 for X2 message transmission.

步骤 407 : HeNB GW发送 MME配置传输消息到 HeNB2。 HeNB GW可根据 MME配置传输消息中的 HeNB2 ID确定将 MME配置传输消息发送给 HeNB2。 MME配置传输消息包括了 eNBl ID、 TAI1、 HeNB2 ID、 TAI2。 eNB 配置传输消息中也可以携带源 eNBl的用于 X2消息传输的 SCTP层的 TNL 地址。 Step 407: The HeNB GW sends an MME configuration transmission message to the HeNB2. The HeNB GW may determine to send the MME configuration transmission message to the HeNB 2 according to the HeNB2 ID in the MME configuration transmission message. The MME configuration transmission message includes an eNB1 ID, a TAI1, a HeNB2 ID, and a TAI2. The eNB configuration transmission message may also carry the TNL address of the SCTP layer of the source eNB1 for X2 message transmission.

步骤 408: 目标 HeNB2响应 eNB配置传输消息给 HeNB GW。 eNB配置传输消息中包括了 HeNB2 ID、 TAI2、 eNBl ID、 TAIL 因为 eNBl和 HeNB2 之间需要通过 X2 GW建立代理的 X2连接，所以 HeNB2在发送给 HeNB GW 的 eNB配置传输消息中包括了在步骤 401中获取的 X2 GW的用于 X2消息传输的 SCTP层的 TNL地址。 Step 408: The target HeNB2 responds to the eNB configuration transmission message to the HeNB GW. The eNB configuration transmission message includes the HeNB2 ID, the TAI2, the eNB1 ID, and the TAIL. Because the X2 connection needs to be established between the eNB1 and the HeNB2 through the X2 GW, the HeNB2 includes the eNB configuration transmission message sent to the HeNBGW in step 401. The TNL address of the SCTP layer for X2 GW for the X2 GW obtained in the acquisition.

ID ,发送 MME配置传输消息给 eNBl。 MME配置传输消息包括了 HeNB2 ID、 TAI2、 eNBl ID、 TAI1、 X2 GW的用于 X2消息传输的 SCTP层的 TNL地址。 ID, sending MME configuration transmission message to eNB1. The MME configuration transmission message includes the TNL address of the SCTP layer for X2 message transmission of the HeNB2 ID, TAI2, eNB1 ID, TAI1, X2 GW.

步骤 41 1 : eNBl根据步骤 410中获取的 X2 GW的用于 X2消息传输的 SCTP层的 TNL地址，与 X2 GW建立用于传输 X2消息的 SCTP连接。 Step 41: The eNB1 establishes an SCTP connection for transmitting the X2 message with the X2 GW according to the TNL address of the SCTP layer of the X2 GW for the X2 message transmission obtained in step 410.

步骤 412: eNBl发送 X2建立请求消息到 X2 GW。 X2建立请求消息中包括了 eNBl的 eNBl ID、 eNBl的服务小区信息、服务小区的相邻小区信息等。 X2 建立请求消息中也可以包括目标 HeNB2 的无线网络层标识（Radio Network Layer Identifier, 简称 RNL ID ) , 例如， HeNB2 ID。 X2 GW在接收到 X2建立请求消息后，可以保存 eNBl ID和 eNBl的用于 X2消息传输的 SCTP层的 IP地址（或 TNL地址 ) 的匹配关系。 Step 412: The eNB1 sends an X2 Setup Request message to the X2 GW. The X2 setup request message includes the eNB1 ID of the eNB1, the serving cell information of the eNB1, the neighbor cell information of the serving cell, and the like. The X2 setup request message may also include a Radio Network Layer Identifier (RNL ID) of the target HeNB2, for example, an HeNB2 ID. X2 GW is receiving After the X2 setup request message, the matching relationship between the eNB1 ID and the IP address (or TNL address) of the SCTP layer of the eNB1 for X2 message transmission may be saved.

步骤 413 : X2 GW根据步骤 412中接收到的 X2建立请求消息中的信息与其存储的信息判断出自己和 HeNB2之间已经存在 X2接口，于是发送 eNB 配置更新消息给 HeNB2。在 eNB配置更新消息的 Served Cells To Add信元中包括了 eNBl的服务小区信息。 Step 413: The X2 GW determines that an X2 interface exists between itself and HeNB2 according to the information in the X2 setup request message received in step 412 and the information stored therein, and then sends an eNB configuration update message to HeNB2. The serving cell information of the eNB1 is included in the Served Cells To Add cell of the eNB configuration update message.

较佳地， X2 GW终止 X2建立请求消息，解析 X2建立请求消息中包括的 eNBl的服务小区的相邻小区的 ECGI, 与自身已经保存的 eNBl服务小区的相邻小区列表做比对。因为步骤 412的 X2建立请求消息中的服务小区的相邻小区的 ECGI包括在 X2 GW自身已经保存的 eNBl服务小区的相邻小区列表中，因此， X2 GW向 X2 建立请求消息中的服务小区的相邻小区所属的 HeNB发送 eNB配置更新消息。 Preferably, the X2 GW terminates the X2 setup request message, and parses the ECGI of the neighboring cell of the serving cell of the eNB1 included in the X2 setup request message, and compares it with the neighbor cell list of the eNB1 serving cell that it has already saved. Because the ECGI of the neighboring cell of the serving cell in the X2 setup request message of step 412 is included in the neighbor cell list of the eNB1 serving cell that the X2 GW itself has saved, the X2 GW establishes the serving cell in the request message to X2. The HeNB to which the neighboring cell belongs transmits an eNB configuration update message.

如果步骤 412的 X2建立请求消息中包括了目标的 HeNB2 ID, 那么， X2 GW终止 X2建立请求消息，解析 X2建立请求消息，从而获取目标端的 HeNB2 ID。 X2 GW将获取到的目标的 HeNB2 ID为索引，在自身保存的 HeNB ID和 IP地址（或 TNL地址）匹配列表中搜索，因为 X2 GW中已经有了目标 HeNB2 ID所匹配的 IP地址（或者 TNL地址 ) , 那么 X2 GW要向该目标 HeNB2发送 eNB配置更新消息。 If the X2 setup request message of step 412 includes the HeNB2 ID of the target, the X2 GW terminates the X2 setup request message and parses the X2 setup request message, thereby acquiring the HeNB2 ID of the target end. The X2 GW searches for the HeNB2 ID of the acquired target, and searches for the HeNB ID and IP address (or TNL address) matching list saved by itself, because the X2 GW already has the IP address matched by the target HeNB2 ID (or TNL). Address), then the X2 GW is to send an eNB configuration update message to the target HeNB2.

步骤 414 : HeNB2 发送 eNB 配置更新确认 ( eNB CONFIGURATION UPDATE ACKNOWLEDGE ) 消息给 X2 GW, 来通知 X2 GW请求的信息更新已经成功地完成。 Step 414: HeNB2 sends an eNB CONFIGURATION UPDATE ACKNOWLEDGE message to the X2 GW to notify the X2 GW that the information update requested has been successfully completed.

步骤 415 : X2 GW 回复 X2 建立响应 (X2 SETUP RESPONSE)消息给 eNBl。 Step 415: The X2 GW replies to the X2 SETUP RESPONSE message to the eNB1.

步骤 416: HeNB3上电后与 HeMS交互， HeMS验证 HeNB3后为该 HeNB3 配置参数。因为 HeNB3是连接到 X2 GW的，因此 HeMS给 HeNB3配置 X2 GW的 IP地址。 TNL地址为 IP地址和端口号的组合。由于用于 X2连接的 SCTP层的 TNL地址的端口号固定为 36422 ,因此 HeMS给 HeNB3配置 X2 GW 的 IP地址就等于 HeMS给 HeNB3配置 X2 GW的 TNL地址。 HeNB3根据 X2 GW的 TNL地址，与 X2 GW建立用于 X2消息传输的 SCTP连接。步骤 417: HeNB3发送 X2建立请求消息给 X2 GW。 X2建立请求消息中包括了 HeNB3 ID、 HeNB3服务小区信息、服务小区的相邻小区信息。 X2 GW 在接收到 X2建立请求消息后 , 可以保存 HeNB3 ID和 HeNB3的用于 X2消息传输的 SCTP层的 IP地址（或 TNL地址 ) 的匹配关系。 Step 416: After HeNB3 is powered on, it interacts with the HeMS, and after the HeMS verifies the HeNB3, it configures parameters for the HeNB3. Since HeNB3 is connected to the X2 GW, the HeMS configures the IP address of the X2 GW to HeNB3. The TNL address is a combination of an IP address and a port number. Since the port number of the TNL address of the SCTP layer for the X2 connection is fixed to 36422, the HeMS configures the X2 GW's IP address for HeNB3 to be equal to the HeMS to configure the X2 GW's TNL address for HeNB3. HeNB3 establishes an SCTP connection for X2 message transmission with the X2 GW according to the TNL address of the X2 GW. Step 417: HeNB3 sends an X2 setup request message to the X2 GW. The X2 setup request message includes the HeNB3 ID, the HeNB3 serving cell information, and the neighbor cell information of the serving cell. After receiving the X2 setup request message, the X2 GW may save the matching relationship between the HeNB3 ID and the IP address (or TNL address) of the SCTP layer of the HeNB3 for the X2 message transmission.

步骤 418: X2 GW发送 X2建立响应消息给 HeNB3。 Step 418: The X2 GW sends an X2 setup response message to the HeNB3.

步骤 419: 与步骤 413类似， X2 GW发送 eNB配置更新消息给 eNB 1。在 eNB配置更新消息的 Served Cells 7b ¾信元中包括 HeNB3的服务小区信息。 Step 419: Similar to step 413, the X2 GW sends an eNB configuration update message to the eNB 1. The serving cell information of the HeNB 3 is included in the Served Cells 7b 3 cells of the eNB configuration update message.

OAM给 X2 GW配置 eNB和 HeNB对之间以及 HeN B和 HeNB对之间的 X2连接方式。例如 , 以 HeNB2为粒度，配置与该 HeNB2建立通过 X2 GW 代理 X2接口的所有 eNB和 HeNB列表，在本实施例中，即 eNBl , 同时，配置与该 HeNB2建立直接 X2接口的所有 eNB和 HeNB列表，在本实施例中 , 即 HeNB3。以 HeNB3为粒度，配置与该 HeNB3建立通过 X2 GW代理 X2 接口的所有 eNB和 HeNB列表，在本实施例中 , 即 eNBl , 同时，配置与该 HeNB3建立直接 X2接口的所有 eNB和 HeNB列表，在本实施例中，即 HeNB2。以 eNBl为粒度，配置与该 eNBl建立通过 X2 GW代理 X2接口的所有 HeNB 列表，在本实施例中 , 即 HeNB2和 HeNB3 , 同时，配置与该 eNBl建立直接 X2接口的所有 HeNB列表，在本实施例中，即为空。 The OAM configures the X2 GW for the X2 GW between the eNB and the HeNB pair and between the HeN B and HeNB pairs. For example, with HeNB2 as a granularity, configure all the eNBs and HeNBs that establish an X2 GW proxy X2 interface with the HeNB2. In this embodiment, that is, eNB1, and configure all eNBs and HeNBs that establish a direct X2 interface with the HeNB2. In this embodiment, that is, HeNB3. Configuring, in the present embodiment, eNB1, and configuring all eNBs and HeNBs that establish a direct X2 interface with the HeNB3, in the HeNB3 as a granularity, and configuring a list of all eNBs and HeNBs that establish a direct X2 interface with the HeNB3. In this embodiment, it is HeNB2. In the embodiment, the HeNB2 and the HeNB3 are configured to establish a direct X2 interface with the eNB1, and the HeNB2 and the HeNB3 are configured to establish a direct X2 interface with the eNB1. In the example, it is empty.

由于 X2 GW处存在 OAM配置的 eNB和 HeNB对之间以及 HeNB和 HeNB对之间的 X2连接方式，因此 X2 GW可以获知 eNB 1和 HeNB3之间是需要建立通过 X2 GW的代理 X2接口的。则 X2 GW可在 eNB配置更新消息的 Served Cells To Add信元中包括 HeNB3服务小区信息。或者 X2 GW除了仍在 eNB配置更新消息的 Served Cells 7b ¾信元中包括 HeNB3服务小区信息外，还在 Served Cells To Add信元中增加指示标识，来通知 eNB 1： eNB 1 和 HeNB3之间需要建立通过 X2 GW的代理 X2接口（例如，设置指示标识为 0或者为 1 ) 。 eNBl保存和 HeNB3的 X2连接方式。 Since there is an X2 connection between the eNB and the HeNB pair and the HeNB and the HeNB pair at the X2 GW, the X2 GW can know that the eNB 1 and the HeNB 3 need to establish a proxy X2 interface through the X2 GW. Then, the X2 GW may include the HeNB3 serving cell information in the Served Cells To Add cell of the eNB configuration update message. Or the X2 GW adds the indication identifier to the Served Cells To Add cell in addition to the HeNB3 serving cell information in the Served Cells 7b 3⁄4 cells of the eNB configuration update message, to notify the eNB 1: that the eNB 1 and the HeNB 3 need to be required. Establish a proxy X2 interface through the X2 GW (for example, set the indication ID to 0 or 1). The eNB1 stores the X2 connection mode with the HeNB3.

eNBl 还可以在后续 X2 GW发送的 eNB 配置更新消息中获取与其他 HeNB的 X2连接方式，继而， eNBl可以保存与其他 HeNB的 X2连接方式，用作于决定后续其他 X2消息的发送路径，即是通过到其他 HeNB直接的 X2 接口发送，还是通过到其他 HeNB的代理 X2接口发送。 The eNB1 may also obtain the X2 connection mode with other HeNBs in the eNB configuration update message sent by the subsequent X2 GW, and then the eNB1 may save the X2 connection mode with other HeNBs, and serve as a transmission path for determining subsequent other X2 messages, that is, Passing X2 directly to other HeNBs Whether the interface sends or sends it through the proxy X2 interface of other HeNBs.

步骤 420: eNB发送 eNB配置更新确认消息给 X2 GW, 来通知 X2 GW 请求的信息更新已经成功地完成。 Step 420: The eNB sends an eNB configuration update confirmation message to the X2 GW to notify the X2 GW that the information update requested has been successfully completed.

步骤 421 : X2 GW根据存储的信息判断出自己和 eNBl之间已经存在 X2 接口，自己和 HeNB2之间也已经存在 X2接口了，按相关技术，应该在发送给 HeNB3的 eNB配置更新消息的 Served Cells 7b ¾信元中包括 eNBl的服务小区信息和 HeNB2的服务小区信息。由于 X2 GW处存在 OAM配置的 eNB 和 HeNB对之间以及 HeNB和 HeNB对之间的 X2连接方式，因此 X2 GW可以获知 eNBl和 HeNB3之间是需要建立通过 X2 GW的代理 X2接口的， HeNB2和 HeNB3之间是需要建立直接的 X2接口的。 X2 GW可以仅仅在 eNB 配置更新消息的 Served Cells 7b ¾信元中包括 eNBl的服务小区信息。或者 X2 GW 除了仍在 Served Cells To Add信元中包括 eNBl 服务小区信息和 HeNB2服务小区信息外，还在 Served Cells To Add信元中增加指示标识，来通知 HeNB3 : eNBl和 HeNB3之间需要建立通过 X2 GW的代理 X2接口， HeNB2和 HeNB3之间需要建立直接的 X2接口。从而后续 HeNB3可以发起到 HeNB2的直接的 X2接口的建立。 HeNB3可以保存该 HeNB3与 eNB和 HeNB的 X2连接方式，用作于决定后续其他 X2消息的发送路径，即是通过到其他 eNB或者 HeNB直接的 X2接口发送，还是通过到其他 eNB或者 HeNB 的代理 X2接口发送。 Step 421: The X2 GW determines that the X2 interface exists between itself and the eNB1 according to the stored information, and the X2 interface already exists between the self and the HeNB2. According to the related technology, the Served Cells of the update message should be configured in the eNB sent to the HeNB3. The 7b 3⁄4 cell includes the serving cell information of the eNB1 and the serving cell information of the HeNB2. Since there is an X2 connection between the eNB and the HeNB pair and the HeNB and the HeNB pair at the X2 GW, the X2 GW can learn that the eNB1 and the HeNB3 need to establish a proxy X2 interface through the X2 GW, and the HeNB2 and A direct X2 interface needs to be established between HeNB3. The X2 GW may include the serving cell information of the eNB1 only in the Served Cells 7b3 cells of the eNB configuration update message. Or the X2 GW adds an indication identifier to the Served Cells To Add cell in addition to the eNB1 serving cell information and the HeNB2 serving cell information, to notify the HeNB3 that the eNB1 and the HeNB3 need to be established. The X2 interface of the X2 GW needs to establish a direct X2 interface between HeNB2 and HeNB3. Therefore, the subsequent HeNB3 can initiate the establishment of the direct X2 interface to the HeNB2. The HeNB3 can save the X2 connection mode of the HeNB3, the eNB, and the HeNB, and use it as a transmission path for determining other subsequent X2 messages, that is, whether it is transmitted through the X2 interface directly to other eNBs or HeNBs, or through the proxy X2 to other eNBs or HeNBs. The interface sends.

步骤 422: HeNB3发送 eNB配置更新确认消息给 X2 GW,来通知 X2 GW 请求的信息更新已经成功地完成。 Step 422: The HeNB3 sends an eNB configuration update confirmation message to the X2 GW to notify the X2 GW that the information update requested has been successfully completed.

应用示例 2 Application example 2

HeMS给 HeNB配置该 HeNB和 eNB对之间以及该 HeNB和其他 HeNB 对之间的 X2连接方式。可以釆用以下方式任意之一： The HeMS configures the HeNB for the X2 connection between the HeNB and the eNB pair and between the HeNB and other HeNB pairs. You can use any of the following methods:

方式一： HeMS可以给每个 HeNB配置与该 HeNB建立直接 X2接口的所有 eNB和 HeNB列表，和与该 HeNB建立通过 X2 GW代理的 X2接口的所有 eNB和 HeNB列表。方式二： HeMS可以仅给每个 HeNB配置与该 HeNB建立直接 X2接口的所有 eNB和 HeNB列表，默认不在配置的建立直接 X2接口列表中的其他的 eNB和该 HeNB之间以及其他 HeNB和该 HeNB之间需要建立通过 X2 GW代理的 X2接口。 Manner 1: The HeMS may configure each HeNB with a list of all eNBs and HeNBs that establish a direct X2 interface with the HeNB, and a list of all eNBs and HeNBs that establish an X2 interface with the X2 GW proxy with the HeNB. Manner 2: The HeMS may configure, for each HeNB, only all eNBs and HeNBs that establish a direct X2 interface with the HeNB. By default, it is not configured between other eNBs in the direct X2 interface list and the HeNB, and other HeNBs and HeNBs. An X2 interface through the X2 GW proxy needs to be established.

方式三： HeMS可以仅给每个 HeNB配置与该 HeNB建立通过 X2 GW代理的 X2接口的所有 eNB和 HeNB列表，默认不在配置的建立通过 X2 GW代理的 X2接口列表中的其他的 eNB和该 HeNB之间以及其他 HeNB和该 HeNB 之间需要建立直接的 X2接口。 Manner 3: The HeMS may configure, for each HeNB, only all eNBs and HeNBs that establish an X2 interface through the X2 GW proxy with the HeNB, and the other eNBs and the HeNBs in the X2 interface list that are configured to pass the X2 GW proxy are not configured by default. A direct X2 interface needs to be established between the other HeNBs and the HeNB.

HeMS给 HeNB配置 HeNB和 eNB对之间以及 HeNB和 HeNB对之间的 X2连接方式不仅局限于上述提及的方式。 The HeMS configures the HeNB for the X2 connection between the HeNB and the eNB pair and between the HeNB and the HeNB pair is not limited to the above-mentioned manner.

HeMS给 HeNB配置该 HeNB和 eNB对之间以及该 HeNB和其他 HeNB 对之间的 X2连接方式， HeNB可以在上电后获取到 X2 GW的 TNL地址后与 X2 GW建立 X2连接的 X2建立请求消息中 , 仅将 HeMS配置的该 HeNB和 eNB对之间的 X2连接方式信息发送给 X2 GW。 The HeMS configures the X2 connection mode between the HeNB and the eNB pair and the HeNB and other HeNB pairs, and the HeNB can obtain the X2 connection request message of the X2 connection with the X2 GW after acquiring the TNL address of the X2 GW after power-on. Only the X2 connection mode information between the HeNB and the eNB pair configured by the HeMS is transmitted to the X2 GW.

基于 X2 GW接收到的 HeNB发送的 HeMS配置的该 HeNB和 eNB对之间的 X2连接方式， X2 GW向 eNB发送消息时，利用该消息中携带的信息向 eNB表明该 eNB基站与该 HeNB之间的 X2连接方式信息。 X2 GW发送的消息包括 NB配置更新消息。 Based on the X2 connection mode between the HeNB and the eNB pair of the HeMS configuration sent by the HeNB, when the X2 GW sends a message to the eNB, the information carried in the message is used to indicate to the eNB between the eNB base station and the HeNB. X2 connection method information. The message sent by the X2 GW includes an NB configuration update message.

例如， X2 GW判断当 HeNB和 eNB之间需要建立直接的 X2连接，那么 X2 GW可不在 eNB配置更新消息的 Served Cells To Add信元中包括该 HeNB 月良务小区信息。另一种可行的方式是： X2 GW除了仍在 eNB配置更新消息的 Served Cells To ^ί ί信元中包括 HeNB的服务小区信息，还在 eNB配置更新消息中将 eNB与 HeNB的 X2连接方式通过指示标识通知给 eNB。 For example, the X2 GW determines that when a direct X2 connection needs to be established between the HeNB and the eNB, the X2 GW may not include the HeNB monthly service cell information in the Served Cells To Add cell of the eNB configuration update message. Another possible way is: the X2 GW includes the serving cell information of the HeNB in the Served Cells that are still in the eNB configuration update message, and also passes the X2 connection mode of the eNB and the HeNB in the eNB configuration update message. The indication identifier is notified to the eNB.

本实施例描述的场景是： eNBl 建立直接 SI连接到 MME, HeNB2通过 HeNB GW建立代理的 S1连接到 MME, HeNB3建立直接 S1连接到 MME, eNBl和 HeNB2之间需要通过 X2 GW建立代理的 X2连接， HeNB2和 HeNB3 之间需要通过 X2 GW建立代理的 X2连接，但是 eNBl和 HeNB3之间需要建立直接的 X2连接，如图 3所示。如图 8所示，本实施例的具体流程主要包括如下步骤： The scenario described in this embodiment is: eNB1 establishes a direct SI connection to the MME, HeNB2 establishes a proxy S1 connection to the MME through the HeNB GW, HeNB3 establishes a direct S1 connection to the MME, and an X2 connection needs to be established between the eNB1 and the HeNB2 through the X2 GW. The H2 connection between the HeNB2 and the HeNB3 needs to be established through the X2 GW, but a direct X2 connection needs to be established between the eNB1 and the HeNB3, as shown in FIG. As shown in FIG. 8, the specific process of this embodiment mainly includes the following steps:

步骤 501 : HeNB2上电后与 HeMS交互， HeMS验证 HeNB2后为该 HeNB2 配置参数。因为 HeNB2是连接到 X2 GW的，因此 HeMS给 HeNB2配置 X2 GW的 IP地址。传输网络层（ Transport Network Layer, 简称 TNL )地址为 IP 地址和端口号（port number ) 的组合。由于用于 X2消息传输的 SCTP层的 TNL地址的端口号固定为 36422,因此 HeMS给 HeNB2配置 X2 GW的 IP地址就等于 HeMS给 HeNB2配置 X2 GW的 TNL地址。 HeNB2根据 X2 GW的 TNL地址，与 X2 GW建立用于 X2消息传输的 SCTP连接。 Step 501: After HeNB2 is powered on, it interacts with the HeMS, and the HeMS verifies the HeNB2 and configures parameters for the HeNB2. Since HeNB2 is connected to the X2 GW, the HeMS configures the X2 GW's IP address for HeNB2. The Transport Network Layer (TNL) address is a combination of an IP address and a port number. Since the port number of the TNL address of the SCTP layer for X2 message transmission is fixed to 36422, the HeMS configures the X2 GW IP address for HeNB2 to be equal to the HeMS to configure the X2 GW TNL address for HeNB2. HeNB2 establishes an SCTP connection for X2 message transmission with the X2 GW according to the TNL address of the X2 GW.

步骤 502: HeNB2发送 X2建立请求消息到 X2 GW。 X2建立请求消息中包括了 HeNB2的 HeNB2 ID、 HeNB2服务小区信息、服务小区的相邻小区信息。 X2 GW在接收到 X2建立请求消息后 , 可以保存 HeNB2 ID和 HeNB2的用于 X2消息传输的 SCTP层的 IP地址（或 TNL地址 ) 的匹配关系。 Step 502: HeNB2 sends an X2 setup request message to the X2 GW. The X2 setup request message includes the HeNB2 ID of the HeNB2, the HeNB2 serving cell information, and the neighbor cell information of the serving cell. After receiving the X2 setup request message, the X2 GW may save the matching relationship between the HeNB2 ID and the IP address (or TNL address) of the SCTP layer of the HeNB2 for the X2 message transmission.

步骤 503： X2 GW回复 X2建立响应消息给 HeNB2。 Step 503: The X2 GW replies to the X2 setup response message to the HeNB2.

步骤 504：当 HeNB2发现相邻的 eNB 1下的小区，并通过 ANR获取 eNB 1 小区的 PCI、 ECGI、 TAC、一个或者多个 PLMN ID。源 HeNB2准备发起 TNL 地址发现过程来获取目标 eNBl的用于 X2消息传输的 SCTP层的 TNL地址。 Step 504: When HeNB2 discovers the cell under the neighboring eNB 1, and acquires the PCI, ECGI, TAC, and one or more PLMN IDs of the eNB 1 cell through the ANR. The source HeNB2 is ready to initiate a TNL address discovery procedure to obtain the TNL address of the SCTP layer of the target eNB1 for X2 message transmission.

步骤 505: 源 HeNB2发送 eNB配置传输消息到 HeNB GW。 eNB配置传输消息包括了源 HeNB2的 HeNB2 ID、源 HeNB2的 TAI2、目标 eNBl的 eNBl ID、目标 eNBl的 TAI1。 eNB配置传输消息也可以携带 X2 GW的用于 X2 消息传输的 SCTP层的 TNL地址，从而可以使得 eNBl发起到 X2 GW的 X2 接口的建立。当然，如果 eNBl和 HeNB2需要建立直接的 X2接口， eNB配置传输消息可以携带 HeNB2的用于 X2消息传输的 SCTP层的 TNL地址，从而可以使得 eNBl发起到 HeNB2的直接 X2接口的建立。 Step 505: The source HeNB2 sends an eNB configuration transmission message to the HeNB GW. The eNB configuration transmission message includes the HeNB2 ID of the source HeNB2, the TAI2 of the source HeNB2, the eNB1 ID of the target eNB1, and the TAI1 of the target eNB1. The eNB configuration transmission message may also carry the TNL address of the X2 GW for the SCTP layer of the X2 message transmission, so that the eNB1 may initiate the establishment of the X2 interface to the X2 GW. Of course, if the eNB1 and the HeNB2 need to establish a direct X2 interface, the eNB configuration transmission message may carry the TNL address of the SCTP layer of the HeNB2 for the X2 message transmission, so that the eNB1 may initiate the establishment of the direct X2 interface to the HeNB2.

步骤 506: HeNB GW在接收到源 HeNB2发送的 eNB配置传输消息后，发送 eNB配置传输消息给 MME。 eNB配置传输消息包括了 HeNB2 ID、 TAI2、 eNBl ID、 TAIL eNB配置传输消息也可以携带 X2 GW的用于 X2消息传输的 SCTP层的 TNL地址，从而可以使得 eNBl发起到 X2 GW的 X2接口的建立。 Step 506: After receiving the eNB configuration transmission message sent by the source HeNB2, the HeNB GW sends an eNB configuration transmission message to the MME. The eNB configuration transmission message includes the HeNB2 ID, the TAI2, the eNB1 ID, and the TAIL eNB configuration transmission message may also carry the X2 GW's TNL address of the SCTP layer for the X2 message transmission, so that the eNB1 may initiate the construction of the X2 interface to the X2 GW. Standing.

步骤 507 : MME发送 MME配置传输消息到 eNBl。 MME可以根据 MME 配置传输消息中的 eNB 1 ID确定将 MME配置传输消息发送给 eNB 1。 MME 配置传输消息包括了 HeNB2 ID、 TAI2、 eNBl ID、 TAIL MME配置传输消息也可以携带 X2 GW的用于 X2消息传输的 SCTP层的 TNL地址，从而可以使得 eNBl发起到 X2 GW的 X2接口的建立。 Step 507: The MME sends an MME configuration transmission message to the eNB1. The MME may determine to send the MME configuration transmission message to the eNB 1 according to the eNB 1 ID in the MME configuration transmission message. The MME configuration transmission message includes the HeNB2 ID, the TAI2, the eNB1 ID, and the TAIL MME configuration transmission message may also carry the X2 GW's TNL address of the SCTP layer for the X2 message transmission, so that the eNB1 may initiate the establishment of the X2 interface to the X2 GW. .

步骤 508: 目标 eNBl响应 eNB配置传输消息给 MME。 eNB配置传输消息中包括了 eNBl ID、 TAI1、 HeNB2 ID、 TAI2、 eNBl的用于 X2消息传输的 SCTP层的 TNL地址。 Step 508: The target eNB1 responds to the eNB configuration transmission message to the MME. The eNB configuration transmission message includes the TNL address of the SCTP layer for X2 message transmission of the eNB1 ID, TAI1, HeNB2 ID, TAI2, and eNB1.

步骤 509: MME在接收到 eNBl发送的 eNB配置传输消息后，可根据 eNB配置传输消息中包括的 TAI2 ,将 MME配置传输消息发送到正确的 HeNB GW。 MME配置传输消息中包括了 eNBl ID、 TAI1、 HeNB2 ID、 TAI2、 eNBl 的用于 X2消息传输的 SCTP层的 TNL地址。 Step 509: After receiving the eNB configuration transmission message sent by the eNB1, the MME may send the MME configuration transmission message to the correct HeNB GW according to the TAI2 included in the eNB configuration transmission message. The MME configuration transmission message includes the TNL address of the SCTP layer for X2 message transmission of the eNB1 ID, TAI1, HeNB2 ID, TAI2, and eNB1.

步骤 510: HeNB GW根据从 MME接收的 MME配置传输消息中的 HeNB2 ID , 发送 MME配置传输消息给 HeNB2。 MME配置传输消息中包括了 eNBl ID、 TAI1、 HeNB2 ID、 TAI2、 eNBl的用于 X2消息传输的 SCTP层的 TNL 地址。 Step 510: The HeNB GW sends an MME configuration transmission message to the HeNB 2 according to the HeNB2 ID in the MME configuration transmission message received from the MME. The MME configuration transmission message includes the TNL address of the SCTP layer for X2 message transmission of the eNB1 ID, TAI1, HeNB2 ID, TAI2, and eNB1.

步骤 51 1 : 根据 HeMS给 HeNB2配置的该 HeNB2与其他 eNB和 HeNB 对之间的 X2连接方式， HeNB2可以获知和 eNB 1之间是需要建立通过 X2 GW 的代理 X2连接的。于是 HeNB2可以发送一条 X2消息到 X2 GW, 从而触发 X2 GW发起到 eNBl的 X2接口的建立过程。该条 X2消息可以是 X2建立请求消息。在该条消息中包括了在步骤 510中接收到的 eNBl的用于 X2消息传输的 SCTP层的 TNL地址。该条 X2消息中也可以包括目标 eNBl的无线网络层标识（ Radio Network Layer Identifier, 简称 RNL ID ) , 例如 eNBl ID。 X2 GW在接收到该条 X2消息后 , 可以保存 eNB 1 ID和 eNB 1的用于 X2消息传输的 SCTP层的 IP地址（或 TNL地址 ) 的匹配关系。 Step 51: According to the X2 connection mode between the HeNB2 and the other eNB and the HeNB pair configured by the HeMS to the HeNB2, the HeNB2 can know that the eNB 1 needs to establish a connection through the X2 GW proxy X2. Then HeNB2 can send an X2 message to the X2 GW, thereby triggering the X2 GW to initiate the establishment process of the X2 interface to eNB1. The X2 message can be an X2 setup request message. The TNL address of the SCTP layer for X2 message transmission of the eNB1 received in step 510 is included in the message. The X2 message may also include a Radio Network Layer Identifier (RNL ID) of the target eNB1, such as an eNB1 ID. After receiving the X2 message, the X2 GW may save the matching relationship between the eNB 1 ID and the IP address (or TNL address) of the SCTP layer of the eNB 1 for X2 message transmission.

步骤 512: X2 GW根据步骤 51 1中获取的 eNBl的用于 X2消息传输的 SCTP层的 TNL地址，发起与 eNBl的用于传输 X2消息的 SCTP连接的建立。步骤 513: X2 GW可以根据步骤 511中获取的 eNBl ID来发送 X2建立请求消息到 eNBl。 X2建立请求消息中包括了 X2 GW ID、 X2 GW的服务小区信息（即 HeNB2的服务小区信息）、服务小区的相邻小区信息等。 Step 512: The X2 GW initiates establishment of an SCTP connection with the eNB1 for transmitting the X2 message according to the TNL address of the SCTP layer for the X2 message transmission of the eNB1 acquired in the step 51 1. Step 513: The X2 GW may send an X2 setup request message to the eNB1 according to the eNB1 ID obtained in step 511. The X2 setup request message includes the X2 GW ID, the serving cell information of the X2 GW (ie, the serving cell information of the HeNB 2), the neighbor cell information of the serving cell, and the like.

步骤 514: eNBl回复 X2建立响应消息给 X2 GW。 X2建立响应消息中包括了 eNBl的 eNBl ID、 eNBl的服务小区信息、服务小区的相邻小区信息。在 X2建立响应消息中可以包括 HeNB2的 RNL ID,例如， HeNB2 ID。 X2 GW 可以在接收到 X2建立响应消息后，取代步骤 511中所提及的，保存 eNBl ID 和 eNBl的用于 X2消息传输的 SCTP层的 IP地址（或 TNL地址 ) 的匹配关系。 Step 514: The eNB1 replies to the X2 setup response message to the X2 GW. The X2 setup response message includes the eNB1 ID of the eNB1, the serving cell information of the eNB1, and the neighbor cell information of the serving cell. The RNL ID of HeNB2, for example, the HeNB2 ID, may be included in the X2 Setup Response message. The X2 GW may, after receiving the X2 Setup Response message, replace the matching relationship between the eNB1 ID and the IP address (or TNL address) of the SCTP layer of the eNB1 for the X2 message transmission, as mentioned in step 511.

步骤 515: 与步骤 511对应， X2 GW回复一条 X2消息给 HeNB2 , 从而通知 HeNB2关于 X2 GW和 eNBl之间的 X2接口已经建立完成。该 X2消息可以是 X2建立响应消息。 Step 515: Corresponding to step 511, the X2 GW replies with an X2 message to the HeNB2, thereby notifying the HeNB2 that the X2 interface between the X2 GW and the eNB1 has been established. The X2 message can be an X2 setup response message.

步骤 516: HeNB3上电后与 HeMS交互， HeMS验证 HeNB3后为该 HeNB3 配置参数。因为 HeNB3是连接到 X2 GW的（ HeNB3和 HeNB2是通过 X2 GW 建立代理 X2连接的），因此 HeMS给 HeNB3配置 X2 GW的 IP地址。 TNL 地址为 IP地址和端口号的组合。由于用于 X2连接的 SCTP层的 TNL地址的端口号固定为 36422, 因此 HeMS给 HeNB3配置 X2 GW的 IP地址就等于 HeMS给 HeNB3配置 X2 GW的 TNL地址。 HeNB3根据 X2 GW的 TNL地址，与 X2 GW建立用于 X2消息传输的 SCTP连接。 Step 516: After the HeNB3 is powered on, it interacts with the HeMS, and after the HeMS verifies the HeNB3, it configures parameters for the HeNB3. Since HeNB3 is connected to the X2 GW (HeNB3 and HeNB2 are connected by the X2 GW to establish a proxy X2), the HeMS configures the X2 GW's IP address for HeNB3. The TNL address is a combination of an IP address and a port number. Since the port number of the TNL address of the SCTP layer for the X2 connection is fixed to 36422, the HeMS configures the X2 GW IP address for HeNB3 to be equal to the HeMS to configure the X2 GW TNL address for HeNB3. HeNB3 establishes an SCTP connection for X2 message transmission with the X2 GW according to the TNL address of the X2 GW.

步骤 517: HeNB3发送 X2建立请求消息给 X2 GW。 X2建立请求消息中包括了 HeNB3 ID、 HeNB3服务小区信息、服务小区的相邻小区信息。 X2 GW 在接收到 X2建立请求消息后 , 可以保存 HeNB3 ID和 HeNB3的用于 X2消息传输的 SCTP层的 IP地址（或 TNL地址 ) 的匹配关系。 Step 517: HeNB3 sends an X2 setup request message to the X2 GW. The X2 setup request message includes the HeNB3 ID, the HeNB3 serving cell information, and the neighbor cell information of the serving cell. After receiving the X2 setup request message, the X2 GW may save the matching relationship between the HeNB3 ID and the IP address (or TNL address) of the SCTP layer of the HeNB3 for X2 message transmission.

HeMS给 HeNB3配置该 HeNB3和 eNB对之间以及该 HeNB3和其他 HeNB对之间的 X2连接方式。例如 , HeMS给 HeNB3配置与该 HeNB3建立直接 X2接口的所有 eNB和 HeNB列表，在本实施例中，即 eNBl , 和与该 HeNB3建立通过 X2 GW代理的 X2接口的所有 eNB和 HeNB列表，在本实施例中，即 HeNB2。 The HeMS configures the X2 connection mode between the HeNB3 and the eNB pair and between the HeNB3 and other HeNB pairs to the HeNB3. For example, the HeMS configures HeNB3 with all eNBs and HeNB lists that establish a direct X2 interface with the HeNB3. In this embodiment, eNB1, and all eNBs and HeNBs that establish an X2 interface with the X2 GW proxy with the HeNB3, In the embodiment, it is HeNB2.

HeNB3可以在 X2建立请求消息中，仅仅将 HeMS配置的该 HeNB3与 eNB对之间的 X2连接方式通过指示标识发送给 X2 GW。例如，基于 HeNB3 处 HeMS的配置的该 HeNB3与其他基站之间的 X2连接方式， HeNB3服务小区的相邻小区是 eNBl服务小区， HeNB3和 eNBl需要建立直接的 X2接口，那么， HeNB3则在服务小区的相邻小区信息中通过标识来将 HeNB3和 eNBl 需要建立直接的 X2接口的信息通知给 X2 GW。或者， HeNB3可以在发送给 X2 GW的 X2建立请求消息中，包括与该 HeNB3建立直接 X2接口的 eNB列表，在本实施例中，即 eNBl , 和与该 HeNB3建立通过 X2 GW代理的 X2接口的 eNB列表，在本实施例中，为空。 X2 GW保存 HeNB发送的 HeMS配置的该 HeNB与 eNB对之间的 X2连接方式。 HeNB3 may only use the HeNB3 configured by the HeMS in the X2 setup request message. The X2 connection mode between the eNB pairs is sent to the X2 GW through the indication identifier. For example, based on the X2 connection mode between the HeNB3 and other base stations in the configuration of the HeMS at the HeNB3, the neighboring cell of the HeNB3 serving cell is the eNB1 serving cell, and the HeNB3 and the eNB1 need to establish a direct X2 interface, then the HeNB3 is in the serving cell. The information of the neighboring cell information is used to notify the X2 GW of the information that the HeNB3 and the eNB1 need to establish a direct X2 interface by using the identifier. Alternatively, HeNB3 may include, in an X2 setup request message sent to the X2 GW, an eNB list that establishes a direct X2 interface with the HeNB3, in this embodiment, that is, eNB1, and an X2 interface that establishes an X2 interface with the HeNB3 through the X2 GW. The eNB list, in this embodiment, is empty. The X2 GW saves the X2 connection mode between the HeNB and the eNB pair configured by the HeMS and transmitted by the HeNB.

步骤 518: X2 GW发送 X2建立响应消息给 HeNB3。 Step 518: The X2 GW sends an X2 setup response message to the HeNB3.

步骤 519: X2 GW发送 eNB配置更新消息给 eNBl。按相关技术，应该在发送给 eNBl 的 eNB 配置更新消息的 Served Cells To Add信元中包括 HeNB3的服务小区信息。由于根据 X2 GW处接收到 HeNB3发送的 HeMS配置的 eNB和 HeNB对之间的 X2连接方式，可以获知 HeNB3和 eNBl之间是需要建立直接的 X2接口的，则 X2 GW不在 eNB配置更新消息的 Served Cells 7b ί信元中包括 HeNB3服务小区信息，即为空。或者 X2 GW仍在 eNB配置更新消息的 Served Cells To ¾信元中包括 HeNB3服务小区信息，同时在 Served Cells To Add信元中增加指示标识，来通知 eNB 1： eNB 1和 HeNB3之间需要建立直接的 X2接口。从而后续 eNBl 可以发起到 HeNB3 的直接的 X2接口的建立。 Step 519: The X2 GW sends an eNB configuration update message to the eNB1. According to the related art, the serving cell information of the HeNB 3 should be included in the Served Cells To Add cell of the eNB configuration update message transmitted to the eNB1. Since the X2 connection mode between the eNB and the HeNB pair of the HeMS configuration transmitted by the HeNB3 is received at the X2 GW, it can be known that the direct X2 interface needs to be established between the HeNB3 and the eNB1, and the X2 GW is not in the Served configuration update message. The Cells 7b ί cell includes HeNB3 serving cell information, that is, it is empty. Or the X2 GW still includes the HeNB3 serving cell information in the Served Cells To3 cell of the eNB configuration update message, and adds an indication identifier to the Served Cells To Add cell to notify the eNB 1: that the eNB 1 and the HeNB 3 need to be directly established. The X2 interface. Therefore, the subsequent eNB1 can initiate the establishment of a direct X2 interface to HeNB3.

eNBl 还可以在后续 X2 GW发送的 eNB 配置更新消息中获取与其他 HeNB的 X2连接方式，继而 eNBl可以保存与其他 HeNB的 X2连接方式，用作于决定后续其他 X2消息的发送路径，即是通过到其他 HeNB直接的 X2 接口发送，还是通过到其他 HeNB的代理 X2接口发送。 The eNB1 may also obtain the X2 connection mode with other HeNBs in the eNB configuration update message sent by the subsequent X2 GW, and then the eNB1 may save the X2 connection mode with other HeNBs, and use it as a transmission path for determining other subsequent X2 messages, that is, Send to the X2 interface of other HeNBs directly, or by sending it to the proxy X2 interface of other HeNBs.

步骤 520: eNB发送 eNB配置更新确认消息给 X2 GW, 来通知 X2 GW 请求的信息更新已经成功地完成。 Step 520: The eNB sends an eNB configuration update confirmation message to the X2 GW to notify the X2 GW that the information update requested has been successfully completed.

步骤 521： X2 GW发送 eNB配置更新消息给 HeNB3。由于 X2 GW根据存储的信息判断出自己和 eNB 1之间已经存在 X2接口、自己和 HeNB2之间也已经存在 X2接口了，则在 eNB配置更新消息的 Served Cells To Add信元中包括 eNBl 的服务小区信息和 HeNB2的服务小区信息。 HeNB3可以根据 HeMS配置的该 HeNB3与其他 eNB和 HeNB对之间的 X2连接方式，后续仍可发起到 eNBl的直接的 X2接口的建立。 Step 521: The X2 GW sends an eNB configuration update message to the HeNB 3. Since the X2 GW determines that the X2 interface already exists between itself and the eNB 1, and the X2 interface already exists between itself and the HeNB 2 according to the stored information, the Served Cells To Add cell of the eNB configuration update message is configured. The serving cell information of the eNB1 and the serving cell information of the HeNB2 are included. The HeNB3 can still initiate the establishment of the direct X2 interface to the eNB1 according to the X2 connection mode between the HeNB3 and other eNB and HeNB pairs configured by the HeMS.

当然，由于 X2 GW根据接收到 HeNB3发送的 HeMS配置的 eNB和 HeNB 对之间的 X2连接方式，可以获知 HeNB3和 eNBl之间是需要建立直接的 X2 接口的， X2 GW可以仅仅在 eNB配置更新消息的 Served Cells To Add信元中包括 HeNB2的服务小区信息。或者 X2 GW除了在 Served Cells To Add信元中包括 eNBl的服务小区信息和 HeNB2的服务小区信息夕卜，还在 Served Cells To Add信元中增加指示标识 , 来通知 HeNB3： eNBl和 HeNB3之间需要建立直接的 X2接口， HeNB2和 HeNB3之间需要建立通过 X2 GW代理的 X2接口。步骤 522: HeNB3发送 eNB配置更新确认消息给 X2 GW,来通知 X2 GW 请求的信息更新已经成功地完成。 Of course, because the X2 GW receives the X2 connection between the eNB and the HeNB pair configured by the HeMS configured by the HeNB3, it can be known that a direct X2 interface needs to be established between the HeNB3 and the eNB1, and the X2 GW can only configure the update message in the eNB. The Served Cells To Add cell includes the serving cell information of the HeNB2. Or the X2 GW includes the serving cell information of the eNB1 and the serving cell information of the HeNB2 in the Served Cells To Add cell, and adds an indication identifier to the Served Cells To Add cell to notify the HeNB3 that the eNB1 and the HeNB3 need to be required. A direct X2 interface is established, and an X2 interface through the X2 GW proxy needs to be established between HeNB2 and HeNB3. Step 522: The HeNB3 sends an eNB configuration update confirmation message to the X2 GW to notify the X2 GW that the information update requested has been successfully completed.

应用示例 3 Application example 3

在本示例中 HeMS给 HeNB配置该 HeNB和 eNB对之间以及该 HeNB和其他 HeNB对之间的 X2连接方式。可选地，可釆用如示例 2中的三种方式任意之一，此处不再赘述。 In this example, the HeMS configures the HeNB for the X2 connection between the HeNB and the eNB pair and between the HeNB and other HeNB pairs. Optionally, any one of the three methods in the example 2 may be used, and details are not described herein again.

The HeNB may configure the HeNB and the eNB configured by the HeMS in the X2 setup request message for establishing an X2 connection with the X2 GW. The X2 connection mode information is sent to the X2 GW.

基于 X2 GW接收到的 HeNB发送的 HeMS配置的该 HeNB和 eNB对之间的 X2连接方式， X2 GW向 eNB发送消息时，利用该消息中携带的信息向 eNB表明该 eNB基站与该 HeNB之间的 X2连接方式信息。 X2 GW发送的消息包括 X2建立请求消息。 Based on the X2 connection mode between the HeNB and the eNB pair of the HeMS configuration sent by the HeNB, when the X2 GW sends a message to the eNB, the information carried in the message is used to indicate to the eNB between the eNB base station and the HeNB. X2 connection method information. The message sent by the X2 GW includes an X2 setup request message.

例如， X2 GW判断当 HeNB和 eNB之间需要建立直接的 X2连接，那么 X2 GW可不在 X2建立请求消息的 Servei Ceto信元中包括该 HeNB服务小区信息。另一种可行的方式是： X2 GW除了仍在 X2建立请求消息中的 &rw?i Ceto信元中包括 HeNB的服务小区信息，还在 X2建立请求消息中将 eNB与 HeNB的 X2连接方式通过指示标识通知给 eNB。 For example, the X2 GW determines that when a direct X2 connection needs to be established between the HeNB and the eNB, the X2 GW may not include the HeNB serving cell in the Servei Ceto cell of the X2 Setup Request message. Information. Another possible way is: the X2 GW includes the serving cell information of the HeNB in the &rw?i Ceto cell in the X2 setup request message, and the X2 connection mode of the eNB and the HeNB is also indicated in the X2 setup request message. The identity is notified to the eNB.

步骤 601-步骤 610: 与应用示例 2中步骤 501-步骤 510相同，此处不再赘述。 Step 601 - Step 610: The same as Step 501 - Step 510 in Application Example 2, and details are not described herein again.

步骤 61 1-步骤 613 : 此时 HeNB3开机了。与应用示例 2中步骤 516-步骤 518相同，此处不再赘述。 Step 61 1-Step 613: At this time, HeNB3 is powered on. The same as step 516-step 518 in the application example 2, and details are not described herein again.

步骤 614-步骤 618: 与应用示例 2中步骤 51 1-步骤 515部分相同，不同之处在于：在步骤 616中，由于 X2 GW处接收到 HeNB3发送的 HeMS配置的 eNB和 HeNB对之间的 X2连接方式，可以获知 HeNB3和 eNBl之间是需要建立直接的 X2接口的， X2 GW可以仅仅在 X2建立请求消息的 Served Cells 信元中包括 HeNB2的服务小区信息。或者 X2 GW仍在 X2建立请求消息的 Served Cells信元中包括 HeNB3的服务小区信息，同时在 Served Cells信元中增加指示标识，来通知 eNBl : eNBl和 HeNB3之间需要建立直接的 X2接口。 Step 614-Step 618: The same as Step 51 1-Step 515 in Application Example 2, except that: In step 616, X2 between the eNB and the HeNB pair of the HeMS configuration transmitted by HeNB3 is received at the X2 GW. In the connection mode, it can be known that the direct X2 interface needs to be established between the HeNB3 and the eNB1, and the X2 GW can include the serving cell information of the HeNB2 only in the Served Cells of the X2 setup request message. Or the X2 GW still includes the serving cell information of the HeNB3 in the Served Cells of the X2 setup request message, and adds an indication identifier to the Served Cells to notify the eNB1 that a direct X2 interface needs to be established between the eNB1 and the HeNB3.

步骤 619-步骤 620: 与应用示例 2中步骤 521-步骤 522相同，此处不再赘述。应用示例 4 Step 619 - Step 620: The same as Step 521 - Step 522 in Application Example 2, and details are not described herein again. Application example 4

HeNB与相邻 HeNB在建立 X2接口的时候通过指示标识获取 HeMS给该相邻 HeNB配置的该相邻 HeNB与其他 eNB的 X2连接方式。 HeNB仅将与该 HeNB建立 X2连接的目标 eNB和该相邻 HeNB的 X2连接方式通过指示标识包括在 X2建立请求消息中发送给 X2 GW。 The HeNB and the neighboring HeNB obtain the X2 connection mode of the neighboring HeNB and other eNBs configured by the HeMS to the neighboring HeNB by using the indication identifier when establishing the X2 interface. The HeNB only sends the X2 connection mode of the target eNB that establishes the X2 connection with the HeNB and the neighboring HeNB to the X2 GW through the indication of the indication in the X2 setup request message.

X2 GW在与该目标 eNB建立 X2连接的过程中，将该目标 eNB和上述相邻 HeNB的 X2连接方式信息发送给该目标 eNB , 以至于后续，如果该目标 eNB到相邻 HeNB需要建立通过 X2 GW的代理 X2连接的时候，该目标 eNB可以直接发起到该相邻 HeNB的 X2连接建立过程。 The X2 GW sends the X2 connection mode information of the target eNB and the neighboring HeNB to the target eNB in the process of establishing an X2 connection with the target eNB, so that if the target eNB needs to establish an X2 to the neighboring HeNB, When the proxy X2 of the GW is connected, the target eNB may directly initiate an X2 connection establishment process to the neighboring HeNB.

本实施例描述的场景是： eNBl 建立直接 SI连接到 MME, HeNB2通过 HeNB GW建立代理的 S1连接到 MME, HeNB3建立直接 S1连接到 MME, eNBl和 HeNB2之间需要通过 X2 GW建立代理的 X2连接， eNBl和 HeNB3 之间需要通过 X2 GW建立代理的 X2连接。 The scenario described in this embodiment is: eNB1 establishes a direct SI connection to the MME, HeNB2 establishes a proxy S1 connection to the MME through the HeNB GW, HeNB3 establishes a direct S1 connection to the MME, and an X2 connection needs to be established between the eNB1 and the HeNB2 through the X2 GW. The X2 connection of the proxy needs to be established between the eNB1 and the HeNB3 through the X2 GW.

Transfer to HeNB2.

如图 10所示，本实施例的具体流程主要包括如下步骤： As shown in FIG. 10, the specific process of this embodiment mainly includes the following steps:

步骤 701-步骤 710: 与应用示例 2中步骤 501-步骤 510相同，此处不再赘述。 Step 701-Step 710: The same as Step 501-Step 510 in Application Example 2, and details are not described herein again.

步骤 711 : 根据 HeMS给 HeNB2配置的该 HeNB2与其他 eNB和 HeNB 之间的 X2连接方式， HeNB2可以获知该 HeNB2和 eNBl之间是需要建立通过 X2 GW的代理 X2连接的。 HeNB2发送 X2建立请求到 X2 GW。 X2建立请求消息中包括 HeNB2 ID、 HeNB2的服务小区信息、 HeNB2相邻小区信息 (即为 HeNB3的服务小区）、目标 eNBl RNL ID (例如， eNBl ID ) 。 HeNB2 在发送给 X2 GW的 X2建立请求消息中通过新增标识来指示 HeNB2相邻小区（即 HeNB3服务小区）所属 HeNB与目标 eNBl的 X2连接方式。 X2建立请求消息可以包括步骤 710中接收到的 eNBl的用于 X2消息传输的 SCTP层的 TNL地址。 X2 GW在接收到该条 X2消息后 , 可以保存 eNB 1 ID和 eNB 1 的用于 X2消息传输的 SCTP层的 IP地址（或 TNL地址 ) 的匹配关系。 Step 711: According to the X2 connection mode between the HeNB2 and the other eNBs and HeNBs configured by the HeMS to the HeNB2, the HeNB2 can know that the HeNB2 and the eNB1 need to establish a connection through the X2 GW proxy X2. HeNB2 sends an X2 setup request to the X2 GW. The X2 setup request message includes the HeNB2 ID, the serving cell information of the HeNB2, the HeNB2 neighbor cell information (that is, the serving cell of the HeNB3), and the target eNB1 RNL ID (for example, the eNB1 ID). HeNB2 indicates that HeNB2 is adjacent by adding a new identifier in the X2 setup request message sent to the X2 GW. The X2 connection mode of the HeNB to which the zone (ie, the HeNB3 serving cell) belongs and the target eNB1. The X2 Setup Request message may include the TNL address of the SCTP layer for the X2 message transmission of the eNB1 received in step 710. After receiving the X2 message, the X2 GW may save the matching relationship between the eNB 1 ID and the IP address (or TNL address) of the SCTP layer of the eNB 1 for the X2 message transmission.

步骤 712-步骤 715: 与步骤 512-步骤 515类似。不同之处在于：在步骤 Step 712 - Step 715: Similar to step 512 - step 515. The difference is: in the steps

713中，在 X2 GW发送给 eNBl的 X2建立请求消息中包括了 HeNB2 ID、 HeNB2服务小区信息、 HeNB2相邻小区信息（即为 HeNB3的服务小区 ) 、目标 eNBl RNL ID (例如 eNBl ID ) 。此外，在该 X2建立请求消息中利用新增标识来指示在步骤 711中获取的 HeNB2相邻小区（即 HeNB3服务小区 ) 所属 HeNB与目标 eNBl的 X2连接方式。在步骤 715中， X2 GW发送 X2 建立响应消息给 eNB 1 ,该 X2建立响应消息包括 eNB 1的 RNL ID ,例如， eNB 1 ID等。 In 713, the X2 setup request message sent by the X2 GW to the eNB1 includes the HeNB2 ID, the HeNB2 serving cell information, the HeNB2 neighbor cell information (that is, the serving cell of the HeNB3), and the target eNB1 RNL ID (for example, the eNB1 ID). In addition, the new identifier is used in the X2 setup request message to indicate the X2 connection mode of the HeNB and the target eNB1 to which the HeNB2 neighboring cell (ie, the HeNB3 serving cell) acquired in step 711 belongs. In step 715, the X2 GW sends an X2 Setup Response message to the eNB 1, the X2 Setup Response message including the RNL ID of the eNB 1, for example, the eNB 1 ID, and the like.

步骤 716-步骤 719: 当 eNBl要建立到 HeNB3的 X2连接的时候， eNBl 根据在步骤 713中接收到的 HeNB3与 eNBl的 X2连接方式，发现 eNBl需要和 HeNB3建立通过 X2 GW的代理 X2连接。于是 eNBl发送 X2建立请求消息到 X2 GW, X2 GW发送 X2建立请求消息到 HeNB3 , HeNB3回复 X2 建立响应消息到 X2 GW, X2 GW回复 X2建立响应消息到 eNBl。 X2建立请求和响应消息中都包括了目标端的 RNL ID。 Step 716: Step 719: When the eNB1 is to establish an X2 connection to the HeNB3, the eNB1 finds that the eNB1 needs to establish a proxy X2 connection with the HeNB3 through the X2 GW according to the X2 connection mode of the HeNB3 and the eNB1 received in step 713. Then, the eNB1 sends an X2 setup request message to the X2 GW, the X2 GW sends an X2 setup request message to the HeNB3, the HeNB3 replies with the X2 setup response message to the X2 GW, and the X2 GW replies with the X2 setup response message to the eNB1. The RNL ID of the target is included in both the X2 setup request and the response message.

需要指出的是，在上述四个实施例中的中，均显示的是 HeNB GW ( S1 GW )和 X2 GW是不同的物理实体的情况，本发明实施例也同样适用于 SI GW 和 X2 GW是同一个物理实体中的两个逻辑功能体的情况，即 SI GW和 X2 GW是 HeNB GW中的两个逻辑功能体的情况。 It should be noted that, in the above four embodiments, the case where the HeNB GW (S1 GW ) and the X2 GW are different physical entities is shown, and the embodiment of the present invention is also applicable to the SI GW and the X2 GW. The case of two logical functions in the same physical entity, that is, the case where the SI GW and the X2 GW are two logical functions in the HeNB GW.
