Application example 4
HeMS to HeNB configuration HeNB and eNB between and HeNB and HeNB between X2 connected mode, preferably adopt three kinds of modes in example 2 one of any.
HeNB and adjacent HeNB obtain HeMS to this adjacent HeNB of this adjacent HeNB configuration and the X2 connected mode of other eNB by sign in setting up X2 interface.HeNB is only included in X2 by the X2 connected mode of setting up target eNB that X2 is connected and this adjacent HeNB with this HeNB by sign and sets up and in request message, send to X2GW.
X2GW is setting up in the process that X2 is connected with this target eNB, the X2 connected mode information of this target eNB and above-mentioned adjacent HeNB is sent to this target eNB, to such an extent as to follow-up, if this target eNB to adjacent HeNB need to set up by X2GW act on behalf of X2 connect time, this target eNB can directly be initiated to this adjacent HeNB X2 connect process of establishing.
The scene that the present embodiment is described is: eNB1 sets up direct S1 and is connected to MME, the S1 that HeNB2 sets up agency by HeNB GW is connected to MME, HeNB3 sets up direct S1 and is connected to MME, between eNB1 and HeNB2, need the X2 that sets up agency by X2GW to connect, between eNB1 and HeNB3, need the X2 that sets up agency by X2GW to connect.
In the present embodiment, HeNB2 and HeNB3 are adjacent, HeNB2 and HeNB3 have set up direct X2 interface, and HeNB2 is in setting up X2 interface with HeNB3, HeNB3 by the HeNB of HeMS configuration and eNB between X2 connected mode be transferred to HeNB2.
As shown in figure 10, the idiographic flow of the present embodiment mainly comprises the steps:
Step 701-step 710: identical with step 501-step 510 in application example 2, repeat no more herein.
Step 711: to the X2 connected mode between this HeNB2 and other eNB and the HeNB of HeNB2 configuration, HeNB2 can know between this HeNB2 and eNB1 it is to need the X2 that acts on behalf of setting up by X2GW to connect according to HeMS.HeNB2 sends X2 and sets up request to X2GW.X2 sets up service cell information, HeNB2 adjacent cell information (being the Serving cell of HeNB3), the such as eNB1ID of target eNB 1RNL ID(that request message comprises HeNB2ID, HeNB2).HeNB2 indicates the X2 connected mode of the affiliated HeNB in HeNB2 neighbor cell (being HeNB3 Serving cell) and target eNB 1 in the X2 that sends to X2GW sets up request message by newly-increased mark.X2 sets up the TNL address that request message can comprise the SCTP layer for X2 transmission of messages of the eNB1 receiving in step 710.X2GW is receiving after this X2 message, can preserve the matching relationship of the IP address (or TNL address) of the SCTP layer for X2 transmission of messages of eNB1ID and eNB1.
Step 712-step 715: similar with step 512-step 515.Difference is: in step 713, send to the X2 of eNB1 to set up request message comprised HeNB2ID, HeNB2 service cell information, HeNB2 adjacent cell information (being the Serving cell of HeNB3), such as eNB1ID of target eNB 1RNL ID(at X2GW).In addition, in setting up request message, this X2 utilize newly-increased mark to indicate the X2 connected mode of the affiliated HeNB in the HeNB2 neighbor cell (being HeNB3 Serving cell) obtaining and target eNB 1 in step 711.In step 715, X2GW sends X2 and sets up response message to eNB1, and this X2 sets up the RNL ID that response message comprises eNB1, such as eNB1ID etc.
Step 716-step 719: in the time that eNB1 will be established to the X2 connection of HeNB3, eNB1, according to the HeNB3 receiving in step 713 and the X2 connected mode of eNB1, finds that eNB1 needs to set up and be connected by the X2 that acts on behalf of of X2GW with HeNB3.So eNB1 sends X2 and sets up request message to X2GW, X2GW sends X2 and sets up request message to HeNB3, and HeNB3 replys X2 and sets up response message to X2GW, and X2GW replys X2 and sets up response message to eNB1.X2 sets up the RNL ID that has comprised destination end in request and response message.
It is to be noted, in in above-mentioned four embodiment, that all show is HeNB GW(S1GW) and X2GW be the situation of different physical entity, the present invention is applicable to too S1GW and X2GW is the situation of two logic function bodies in same physical entity, and S1GW and X2GW are the situations of two logic function bodies in HeNB GW.
