Abstract

The present application relates to the technical field of wireless communications, particularly to a method, a system, and a device for the establishment of an X2 interface, for use in a network structure having a home evolved-node base (eNB) gateway (HeNB GW), allowing the establishment of the X2 interface between the HeNB GW and the eNB. In the method, a first network-side device acquires the X2 transport address of a second network-side device via a mobility management entity (MME) (501); on the basis of the X2 transport address of the second network-side device, the first network-side device establishes an X2 interface with the second network-side device (502). As the first network-side is capable of acquiring the X2 transport address of the second network-side device, an X2 interface is established between the first network-side device and the second network-side device. For a network structure having a HeNB GW, this allows for the establishment of an X2 interface between the eNB and the HeNB GW, thereby improving the network-side performance.

The second network side device 20 is configured to send the X2 transport address of the second network side device 20 to the MME 30.

其中，如果第一网络侧设备 10是 eNB，则第二网络侧设备 20是 He B GW; 如果第一网各侧设备 10是 HeNB GW, 则第二网络侧设备 20是 eNB。 If the first network side device 10 is an eNB, the second network side device 20 is a He B GW; if the first network side device 10 is a HeNB GW, the second network side device 20 is an eNB.

方式一、第一网络侧设备 10是 eNB, 第二网络侧设备 20是 HeNB GW。 Manner 1: The first network side device 10 is an eNB, and the second network side device 20 is a HeNB GW.

具体的， eNB向 MME发送 eNB ID和 HeNB GW ID; Specifically, the eNB sends an eNB ID and a HeNB GW ID to the MME.

HeNB GW在收到 MME发送的 eNB ID和 HeNB GW ID后，将自身的 X2传输地址、 eNB ID和 HeNB GW ID发送给 MME; After receiving the eNB ID and the HeNB GW ID sent by the MME, the HeNB GW sends its own X2 transport address, eNB ID, and HeNB GW ID to the MME;

MME将来自 HeNB GW的 X2传输地址、 eNB ID和 HeNB GW ID转发给 eNB ID对应的 e B。 The MME forwards the X2 transport address, the eNB ID, and the HeNB GW ID from the HeNB GW to the e B corresponding to the eNB ID.

在实施中， eNB可以通过下列方案获取 HeNB GW ID: In an implementation, the eNB may obtain the HeNB GW ID by using the following scheme:

eNB确定与 HeNB GW连接的 HeNB的第一信息，并向 MME发送 eNB ID和第一信息，其中第一信息是 HeNB的 TAI和 /或 HeNB的 ΠΧ TAI和 /或 ID的意思是可以是 TAI, 也可以是 ID, 还可以是 TAI和 ID, 具体第一信息中携带什么信息可以根据需要设定，但是要保证 MME可以根据第一信息找到对应的 HeNB。下面文中的出现的 "和 /或" 以及第二、第三信息与上述意思类似，不再重复解释）； The eNB determines the first information of the HeNB connected to the HeNB GW, and sends the eNB ID and the first information to the MME, where the first information is the TAI of the HeNB and/or the TeNB and/or the ID of the HeNB means that the TAI may be It can also be an ID, and can also be a TAI and an ID. What information is carried in the specific first information can be set as needed, but it is ensured that the MME can find the corresponding HeNB according to the first information. The "and/or" and second and third information appearing in the following text are similar to the above, and will not be repeated.)

MME根据第一信息，确定 HeNB所属的 HeNB GW的 HeNB GW ID , 并将 HeNB GW ID返回给 eNB ID对应的 eNB。 The MME determines the HeNB GW ID of the HeNB GW to which the HeNB belongs according to the first information, and returns the HeNB GW ID to the eNB corresponding to the eNB ID.

如果第一信息是 ID, 则可以直接根据 ID确定对应的 HeNB , 并进一步确定 HeNB所属的 HeNB GW的 HeNB GW ID; If the first information is an ID, the corresponding HeNB may be directly determined according to the ID, and the HeNB GW ID of the HeNB GW to which the HeNB belongs is further determined;

如果第一信息是 TAI, MME保存有 TAI与 HeNB GW的 HeNB ID的映射关系，可以通过 TAI信息寻址到 HeNB GW的 HeNB GW ID; If the first information is the TAI, the MME stores the mapping relationship between the TAI and the HeNB ID of the HeNB GW, and can be addressed to the HeNB GW ID of the HeNB GW by using the TAI information;

如果第一信息是 ID和 TAI, 则可以选择任意一个确定 HeNB GW ID。 If the first information is ID and TAI, any one of them may be selected to determine the HeNB GW ID.

后面出现的第二信息和第三信息的查找方式与第一信息类似，不再赞述。 The second information and the third information appearing later are similar to the first information and are not mentioned.

eNB可以通过 ANR过程获取与 HeNB GW连接的 HeNB的相关信息，然后根据相关信息确定第一信息。相关信息包括但比限于下列信息中的一种或多种： The eNB may acquire related information of the HeNB connected to the HeNB GW through an ANR process, and then determine the first information according to the related information. Relevant information includes but is limited to one or more of the following information:

E-CGK PCI和 TAI, 其中 TAI包括公共陆地移动网络（Public Land Mobile Network, PLMN )信息和 TAC信息。 E-CGK PCI and TAI, where TAI includes Public Land Mobile Network (PLMN) information and TAC information.

MME还可以根据第一信息，确定 HeNB所属的 HeNB GW的 TAI ,在向 eNB近回 HeNB GW ID的同时还可以返回 HeNB GW的 TAI，此信息可以作为 eNB邻区关系列表中的参数保存，供后续切换以及相关过程使用。 The MME may further determine, according to the first information, a TAI of the HeNB GW to which the HeNB belongs, and return the HeNB to the eNB. The GW ID can also be returned to the TAI of the HeNB GW. This information can be saved as a parameter in the eNB neighbor relationship list for subsequent handover and related procedures.

方式二、第一网络侧设备 10是 eNB , 第二网络侧设备 20是 HeNB GW。 Manner 2: The first network side device 10 is an eNB, and the second network side device 20 is a HeNB GW.

具体的， eNB向 MME发送与 HeNB GW连接的 HeNB的第一信息和 eNB的第二信息，其中第一信息是 HeNB的 TAI和 /或 HeNB的 ID ,第二信息是 eNB的 TAI和 /或 eNB的 ID; Specifically, the eNB sends the first information of the HeNB connected to the HeNB GW and the second information of the eNB to the MME, where the first information is the TAI of the HeNB and/or the ID of the HeNB, and the second information is the TAI and/or the eNB of the eNB. ID

MME将第一信息和第二信息转发给第一信息对应的 HeNB所属的 HeNB GW; The MME forwards the first information and the second information to the HeNB GW to which the HeNB corresponding to the first information belongs;

HeNB GW在收到 MME发送的第一信息和第二信息后，将自身的 X2传输地址、第一信息和第二信息发送给 MME; After receiving the first information and the second information sent by the MME, the HeNB GW sends its X2 transmission address, the first information, and the second information to the MME;

MME将来自 HeNB GW的 X2传输地址、第一信息和第二信息转发给第二信息对应的 e肌 The MME forwards the X2 transport address, the first information, and the second information from the HeNB GW to the e muscle corresponding to the second information.

在实施中， eNB确定第一信息的方案与方式一中 eNB确定第一信息的方案相同，在此不再赘述。 In the implementation, the scheme for determining the first information by the eNB is the same as the scheme for determining the first information by the eNB in the first mode, and details are not described herein again.

在方式二中， _eNB 向 MME发送第一信息， MME此时不是把第一信息直接路由给 HeNB, 而是路由到 HeNB的上层节点，即 HeNB GW。 In the second approach, _e NB transmits a first message to the MME, the MME is not the case the first routing information directly to the HeNB, but routed to the upper node HeNB, i.e. HeNB GW.

具体的， MME在收到第一信息后，判断该第一信息对应的 HeNB是否有上层节点，如果有，则将第一信息发送给上层节点；否则，发送给第一信息对应的 HeNB。 Specifically, after receiving the first information, the MME determines whether the HeNB corresponding to the first information has an upper node, and if yes, sends the first information to the upper node; otherwise, sends the first information to the HeNB corresponding to the first information.

比如， eNB通过 eNB 配置传输 ( eNB configuration transfer )消息发送第一信息，则 MME收到 eNB的 eNB configuration transfer消息后，如果有上层节点，则将其中的自组织网络配置传输信元（ SON Configuration transfer IE )传输到指定的 eNB (或 HeNB )所属的上层节点；如果没有上层节点，则将其中的 SON Configuration transfer IE传输到指定的 eNB (或 HeNB )。 For example, the eNB sends the first information by using an eNB configuration transfer message, and after receiving the eNB configuration transfer message of the eNB, if the MME has an upper node, the eNB is configured to transmit the cell (SON Configuration transfer). IE) transmits to the upper node to which the designated eNB (or HeNB) belongs; if there is no upper node, transmits the SON Configuration transfer IE to the designated eNB (or HeNB).

方式三、第一网络侧设备 10是 HeNB GW, 第二网络侧设备 20是 eNB。 Manner 3: The first network side device 10 is a HeNB GW, and the second network side device 20 is an eNB.

具体的， HeNB GW获取与 HeNB GW连接的 HeNB的第一信息和第二信息，并向 MME 发送第一信息和 eNB的第二信息，其中第一信息是 HeNB的 TAI和 /或 HeNB的 ID, 第二信息是 eNB的 TAI和 /或 eNB的 ID; Specifically, the HeNB GW acquires the first information and the second information of the HeNB that is connected to the HeNB GW, and sends the first information and the second information of the eNB to the MME, where the first information is the TAI of the HeNB and/or the ID of the HeNB. The second information is an TAI of the eNB and/or an ID of the eNB;

MME将第一信息和第二信息转发给第二信息对应的 eNB; The MME forwards the first information and the second information to the eNB corresponding to the second information;

MME将来自 eNB的 X2传输地址、第一信息和第二信息转发给第一信息对应的 HeNB 所属的 HeNB GW。在实施中， He B GW可以通过与 HeNB GW连接的 HeNB获得第一信息和第二信息。具体的，与 HeNB GW连接的 HeNB通过 ANR过程获取 eNB的相关信息，然后根据相关信息确定第二信息。相关信息包括但比限于下列信息中的一种或多种： e B ID、 PCI 和 TAL The MME forwards the X2 transport address, the first information, and the second information from the eNB to the HeNB GW to which the HeNB corresponding to the first information belongs. In an implementation, the He B GW may obtain the first information and the second information through the HeNB connected to the HeNB GW. Specifically, the HeNB connected to the HeNB GW acquires related information of the eNB through an ANR process, and then determines the second information according to the related information. Relevant information includes but is limited to one or more of the following: e B ID, PCI, and TAL

然后，与 HeNB GW连接的 HeNB向 HeNB GW发送 HeNB的第一信息和第二信息。在具体实施中，与 HeNB GW连接的 HeNB可以通过 S1AP消息或 X2AP消息发送第一信息和第二信息。 Then, the HeNB connected to the HeNB GW transmits the first information and the second information of the HeNB to the HeNB GW. In a specific implementation, the HeNB connected to the HeNB GW may send the first information and the second information by using an S1AP message or an X2AP message.

如果通过 X2AP消息发送第一信息和第二信息，则与 HeNB GW连接的 HeNB在传输之前需要和 HeNB GW之间建立 X2接口。 If the first information and the second information are sent through the X2AP message, the HeNB connected to the HeNB GW needs to establish an X2 interface with the HeNB GW before the transmission.

方式四、第一网络侧设备 10是 HeNB GW, 第二网络侧设备 20是 eNB。 Mode 4: The first network side device 10 is a HeNB GW, and the second network side device 20 is an eNB.

GW。 GW.

在实施中， HeNB GW获得第一信息和第二信息的方案与方式三中 HeNB GW获得第一信息和第二信息的方案相同，在此不再赘述。 In the implementation, the scheme in which the HeNB GW obtains the first information and the second information is the same as the scheme in which the HeNB GW obtains the first information and the second information in the third method, and details are not described herein again.

在方式四中， MME将收到的第二信息和第三信息透传给第二信息对应的 eNB, 如果其他节点收到第二信息和第三信息，则传输给更高的节点。 In the fourth method, the MME transparently transmits the received second information and the third information to the eNB corresponding to the second information, and if the other node receives the second information and the third information, transmits the information to the higher node.
