Embodiment 1
[0100] In this embodiment, a macro base station (called eNB A) establishes an indirect X2 interface with a HeNB (called HeNB B) connected to the HeNB gateway (called HeNB GW T), and the HeNB gateway adopts the way of SON information proxy response.
[0101] Step 1. HeNB B obtains configuration information after starting up, which includes the IP address of HeNB GW T, and HeNB B establishes an X2 interface with HeNB GW T according to the IP address of HeNB GW T.
[0102] Step 2. At a certain moment, a certain UE under the cell of macro eNB A discovers the cell of HeNB B and reports that the cell of macro eNB A is a neighboring cell. Macro eNB A hopes to establish an X2 interface to HeNB B, but does not The transport layer IP address of HeNB B is known.
[0103] Step 3. The macro eNB A sends the eNB Configuration Transfer message to the MME, which contains the SON information request indication, the ID and TAI of the base station A, the ID and TAI of the target HeNB B, and may a...
Embodiment 2
[0111] In this embodiment, a macro eNB (referred to as eNB A) establishes an indirect X2 interface with a HeNB (referred to as HeNB B) connected to the HeNB gateway (referred to as HeNB GW T), and the HeNB gateway adopts the method of modifying the SON information returned by the target HeNB way of responding.
[0112] Steps 1 to 4 are the same as in Embodiment 1.
[0113] Step 5. After HeNB GW T receives the MME Configuration Transfer message, it forwards the MMEConfiguration Transfer message to the target HeNB B intact, and the target HeNB B returns the eNB Configuration Transfer message, which contains the ID of HeNB B, the ID of source base station A, Transport layer IP address of HeNB B;
[0114] Step 6. After HeNB GW T receives the eNB Configuration Transfer message, it replaces the transport layer IP address of HeNB B with the IP address of HeNB GW T, and adds HeNB GW T's own ID in the message, and then transfers the modified eNB The Configuration Transfer message is ...
Embodiment 3
[0117] In this embodiment, a HeNB directly connected to the core network establishes an indirect X2 with a HeNB connected to the HeNB gateway, and the HeNB gateway uses the SON information agent to reply.
[0118] The implementation process is the same as that in Embodiment 1, except that the source base station is not a macro eNB, but a HeNB directly connected to the core network.

Abstract
Disclosed are a self-organizing network (SON) information transmission method, system and device, relating to the technical field of wireless communications, for solving the problem of how to realize the SON information acquisition process when establishing an X2 interface of a Home eNodeB gateway proxy. In the present application, a Home eNodeB gateway receives a mobile management entity configuration transfer (MME Configuration Transfer) message sent by a mobile management entity (MME), with the identification information about a source eNB and identification information about a target Home eNodeB being carried therein; the Home eNodeB gateway sends an eNB configuration transfer (eNB Configuration Transfer) message to the MME, with the identification information about the source eNB, identification information about the target Home eNodeB, the IP address of the transport layer of the Home eNodeB gateway, and the identification information about the Home eNodeB gateway being carried therein. The present application can be applied to solve the above-mentioned problem.
Description
technical field [0001] The present invention relates to the field of wireless communication, in particular to a self-organizing network information SON transmission method, system and equipment. Background technique [0002] In the long-term evolution (LTE) system, the macrobase station (eNB) is directly connected to the core network, and the home base station (HeNB) can be directly connected to the core network or connected to the core through a device called HeNB Gateway (HeNB Gateway). network. Due to the introduction of this device, the network topology has changed, so that the X2 interface has two forms. One is a direct X2 interface and the other is an indirect X2 interface. [0003] The so-called direct X2 interface refers to the point-to-point X2 interface established between two base stations. The two base stations can be two macro eNBs or two HeNBs; [0004] The so-called indirect X2 interface refers to the X2 interface established between two base stations thro...
