Embodiment
First make following analysis:
When setting up indirect X2 interface, due to the participation of HeNB gateway, some have occurred SON information access process changes, and SON information access process can have two kinds of implementations.
Mode one: HeNB GW replaces target HeNB to reply, 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 ID of the indication of SON information request, source base station and TAI, target BS, can also comprise the transport layer IP address of source base station;
Step 2:MME receives after eNB Configuration Transfer message, ID and TAI by target BS are addressed to the HeNB GW that target BS is connected to, and send to HeNB GW after the content in message is carried in MMEConfiguration Transfer message;
Step 3:HeNB GW receives after MME Configuration Transfer message, replace target HeNB Y to reply, because now HeNB GW is an agent node, in fact source base station needs to set up one section of X2 with HeNB GW.HeNB GW sends message eNB Configuration Transfer to MME, wherein comprises the ID of the indication of SON information response, target HeNB Y, the ID of the source base station X sending request and the transport layer IP address of HeNB GW;
Step 4:MME sends to source base station X by the content in NB Configuration Transfer by MMEConfiguration Transfer; After base station X receives, think that the IP address obtaining 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 ID of the indication of SON information request, source base station and TAI, target BS, can also comprise the transport layer IP address of source base station;
Step 2:MME receives after eNB Configuration Transfer message, ID and TAI by target BS are addressed to the HeNB GW that target BS is connected to, and the content in message is included in MMEConfiguration Transfer message and sends to HeNB GW;
Step 3:HeNB GW is intactly transmitted to target HeNB Y by MME Configuration Transfer message;
Step 4: target HeNB receives after MME Configuration Transfer message, to HeNB GW, return to eNB Configuration Transfer message, wherein comprise the indication of SON information response, the ID of HeNB Y, the ID of source base station sending request and the transport layer IP address of HeNB Y;
Step 5:HeNB GW receives after the response message of HeNB Y, the transport layer IP address of HeNB Y wherein replaced with to the transport layer IP address of HeNB GW, and out of Memory is constant, then amended eNB Configuration Transfer message is sent to MME;
Step 6:MME sends to source base station X by content in eNB Configuration Transfer by MMEConfiguration Transfer message; After base station X receives, think that the IP address obtaining is exactly the transport layer IP address of target HeNB Y.
Getting behind required transport layer IP address, will set up X2 interface.As previously mentioned, X2 interface is comprised of two sections of X2 interface indirectly, and one section is that HeNB Y follows the X2 interface between HeNB GW, and another section is that base station X is with the X2 interface between HeNB GW.
The process of establishing of X2 interface as shown in Figure 7, after HeNB Y start, can be known by configuration information the transport layer IP address of HeNB GW indirectly, so HeNB Y does not need to initiate SON information access process, just can be established to the X2 interface of HeNB GW.Afterwards, through one network operation period, base station X obtains by aforesaid SON information access process behind the transport layer IP address of HeNB Y, and foundation is connected with the transport layer between HeNB GW, then send X2 Setup Request message, in message, carry ID, the Serving cell list of source base station X.The transport layer address obtaining due to base station X is the address of HeNB GW, but not the address of HeNB Y, therefore this request message finally sends to HeNB GW.HeNBGW receives X2 Setup Request message, returns to X2 Setup Response message, wherein comprises the ID of HeNBGW, and is connected to the community of some HeNB of this gateway, comprising the community that has HeNB Y.So far, the indirect X2 interface between base station X and HeNB Y has been set up.
In above X2 interface process of establishing indirectly, the target that the X2 interface that source base station X initiates is set up is HeNB Y, although the ID of HeNB Y is not included in X2, sets up in request message, and base station X knows this point.But the X2 returning from HeNB GW sets up the ID that the ID comprising response message is HeNB GW, not the ID of HeNB Y.Like this, according to normal treatment mechanism, source base station X can be used as this response message an error message, rather than expects the response receiving, and finally causes base station X cannot set up to the X2 interface between HeNBGW.
Therefore, the embodiment of the present invention has proposed following SON information transferring method, in this method, femto gateway is when the MME Configuration Transfer message of response MME transmission, the identification information of femto gateway need to be sent to MME, make source base station also can obtain the identification information of femto gateway.
