Embodiment
At first make following analysis:
When setting up indirect X2 interface, because the participation of HeNB gateway, some variations have taken place in the SON information access process, and the SON information access process can have two kinds of implementations.
Mode one: HeNB GW replacement target HeNB does and replys, as shown in Figure 5:
Step 1: source base station X sends eNB Configuration Transfer message to MME, wherein comprises ID and the TAI of the indication of SON information request, source base station, the ID and the TAI of target BS, can also comprise the transport layer IP address of source base station;
After step 2:MME receives eNB Configuration Transfer message; ID and TAI through target BS are addressed to the HeNB GW that target BS is connected to, and send to HeNB GW after being carried at the content in the message in the MMEConfiguration Transfer message;
After step 3:HeNB GW receives MME Configuration Transfer message, replace target HeNB Y to do and reply, because this moment, HeNB GW was an agent node, in fact source base station need set up one section X2 with HeNB GW.HeNB GW sends message eNB Configuration Transfer and gives MME, wherein comprises the ID of the indication of SON information response, target HeNB Y, sends the ID of the source base station X that asks and the transport layer IP address of HeNB GW;
Step 4:MME sends to source base station X with the content among the NB Configuration Transfer through MMEConfiguration Transfer; After base station X receives, think that the IP address that obtains is exactly the transport layer IP address of target HeNB Y.
Mode two: the response message that HeNB GW modifying target HeNB returns, as shown in Figure 6:
Step 1: source base station X sends eNB Configuration Transfer message to MME, wherein comprises ID and the TAI of the indication of SON information request, source base station, the ID and the TAI of target BS, can also comprise the transport layer IP address of source base station;
After step 2:MME receives eNB Configuration Transfer message; ID and TAI through target BS are addressed to the HeNB GW that target BS is connected to, and the content in the message is included in the MMEConfiguration Transfer message sends to HeNB GW;
Step 3:HeNB GW intactly is transmitted to target HeNB Y with MME Configuration Transfer message;
After step 4: target HeNB receives MME Configuration Transfer message; Return eNB Configuration Transfer message to HeNB GW, wherein comprise the ID of the indication of SON information response, HeNB Y, the ID that sends the source base station of asking and the transport layer IP address of HeNB Y;
After step 5:HeNB GW receives the response message of HeNB Y, the transport layer IP address of HeNB Y is wherein replaced with the transport layer IP address of HeNB GW, out of Memory is constant, then amended eNB Configuration Transfer message is sent to MME;
Step 6:MME sends to source base station X with content among the eNB Configuration Transfer through MMEConfiguration Transfer message; After base station X receives, think that the IP address that obtains is exactly the transport layer IP address of target HeNB Y.
After getting access to required transport layer IP address, will set up X2 interface.As previously mentioned, X2 interface is made up of two sections X2 interface indirectly, and one section is that HeNB Y follows the X2 interface between the HeNB GW, and another section is that base station X is with the X2 interface between the HeNB GW.
The process of setting up of X2 interface after HeNB Y start, can be known the transport layer IP address of HeNB GW through configuration information as shown in Figure 7 indirectly, so HeNB Y need not initiate the SON information access process, just can be established to the X2 interface of HeNB GW.Afterwards; Through one network operation period, after base station X obtains the transport layer IP address of HeNB Y through aforesaid SON information access process, set up with HeNB GW between transport layer be connected; Send X2 Setup Request message then, carry ID, the Serving cell tabulation of source base station X in the message.Because the transport layer address that base station X obtains is the address of HeNB GW, but not the address of HeNB Y, so this request message finally sends to HeNB GW.HeNBGW receives X2 Setup Request message, returns X2 Setup Response message, wherein comprises the ID of HeNBGW, and is connected to the sub-district of some HeNB of this gateway, comprising the sub-district that HeNB Y is arranged.So far, the indirect X2 interface between base station X and the HeNB Y is set up and is accomplished.
Set up in the process at above indirect X2 interface, the target that the X2 interface that source base station X initiates is set up is HeNB Y, does not set up in the request message though the ID of HeNB Y is included in X2, and base station X knows this point.But the X2 that returns from HeNB GW sets up the ID that the ID that comprises the response message is HeNB GW, is not the ID of HeNB Y.Like this, according to normal handling mechanism, source base station X can be used as this response message an error message, rather than the response of expectation reception, finally causes base station X can't set up to the X2 interface between the HeNBGW.
Therefore; The embodiment of the invention has proposed following SON information transferring method; In this method; Femto gateway is when the MME Configuration Transfer message that response MME sends; The identification information of femto gateway need be sent to MME, make source base station also can access the identification information of femto gateway.
