If it should be noted that be S1 switching in this step, then source base station sends handover request message to MME
(HANDOVER REQUIRED), MME sends handover request message (HANDOVER to target DeNB again
REQUEST)。
Step 402, target DeNB receives handover request message, can therefrom know Target cell and additional reconstruction information list.
If (as a RN under source base station is this DeNB, X2 switches the community of the RN belonged under this DeNB in list
Presumable in additional reconstruction information list in request message is the community that under this DeNB, other RN set up), then DeNB will
As above reconstruction information must forward (not having strict sequential to limit with replying switching request acknowledgement message) to these communities
Corresponding RN (may respectively to should multiple RN under DeNB).If additional reconstruction information list having and belonging to DeNB
The community of self, DeNB can retain these information.
Step 403, if UE is to Target cell handoff failure, then UE reselects community and initiates to rebuild to the community chosen.
If UE selects to have initiated RN community as above to rebuild, then required to the reconstruction of this community because of the existing UE of this RN
Information, then rebuild and be probably successfully (otherwise inevitable failure).
Preferred embodiment three
When performing switching in the network being deployed with RN, source base station (referring to common eNB or RN) is reported choosing by the measurement of UE

Sending handover request message (HANDOVER REQUEST) to DeNB, message includes Target cell and additional reconstruction letter
Breath list.Wherein, Target cell is RN community, may comprise the DeNB belonging to target RN in additional reconstruction information list
Community and this DeNB under the community of other RN, but source base station cannot be distinguished by Liang Zhong community, it is believed that is all DeNB community.
Step 502, when Target cell is RN community, after DeNB receives handover request message, although know Target cell
It is the community of a RN, but still from message, obtains additional reconstruction information list.It is belonged in addition to target RN if list has
The community that he RN sets up, DeNB just will rebuild information forwarding (must not have strict sequential with replying switching request acknowledgement message
Limit) to RN corresponding to these communities (may respectively to should multiple RN under DeNB, if additional reconstruction information list
In have the community belonging to DeNB self, DeNB can retain these information).The handover request that DeNB sends to target RN disappears
Will be free from being not belonging to the community of target RN in additional reconstruction information list in breath.
Step 503, if UE is to the handoff failure of Target cell, then UE reselects community and the community chosen is initiated weight
Build.If UE selects to have initiated potential rebuilding community as above to rebuild, then because of the existing UE weight to this community in base station
Build required information, then rebuild and be probably successfully (otherwise inevitable failure).
Preferred embodiment four
When performing switching in the network being deployed with RN, source base station (referring to common eNB or RN) is reported choosing by the measurement of UE
Select a Target cell, one or more potential rebuilding community.Because the eNB ID of RN with DeNB is identical, no matter target is little
District is really DeNB community or RN community, and at source base station, these communities of selection are all belonging to DeNB's.Also
That is, even if Target cell is RN community, source base station only will be considered that community is DeNB, i.e. will the letter of these communities
Breath is included in handover request message and is sent to target DeNB.
In this case, DeNB can therefrom obtain Target cell and additional reconstruction information list after receiving handover request message,
And according to the information of these communities, by handover request message with rebuild must information be transmitted to respectively RN corresponding to community (if attached

Because current Target cell is RN community, DeNB also can be after receiving handover request message, according to Target cell ID
Directly forward messages to the RN of its correspondence.RN, after receiving handover request message, therefrom obtains additional reconstruction information list,
If wherein there being the community being not belonging to self, RN just by required for the reconstruction of these communities information back to DeNB, then by DeNB
Information must retain rebuilding or be transmitted to the RN of correspondence according to these cell informations.
If UE is to Target cell handoff failure, then UE reselects community and initiates to rebuild to the community chosen.If UE
Select to have initiated potential rebuilding community as above to rebuild, then have the UE required information of reconstruction to this community because of base station,
Then rebuild and be probably successfully (otherwise inevitable failure).
Fig. 6 is the interaction diagrams of the processing method of the community switching according to the preferred embodiment of the present invention four, as it is shown in figure 5, bag
Include the steps 601 to step 603.
Step 601, when source base station initiates X2 switching (being also likely to be S1 switching), source base station sends switching to MME please
Seeking message (HANDOVER REQUIRED), MME sends handover request message (HANDOVER to target DeNB again
REQUEST).In handoff procedure, the message transmission between source base station and target DeNB all can be via MME (as directed switching
Request confirms message), but this has no effect on inventive point content.It should be noted that if source base station is RN, according to Relay
Framework, it can regard affiliated DeNB as MME, i.e. DeNB is that it acts on behalf of the function of MME, say, that MME
The really DeNB belonging to the RN of source, and MME that should be real between this DeNB and target DeNB, the transmission of switching message
Also will be passed through it.
Step 602, when Target cell is RN community, message is turned by DeNB according to Target cell ID in handover request message
Send to target RN.Target RN knows additional reconstruction information list from message, if wherein having the community being not belonging to oneself, RN
Just (strict sequential must not had to limit with replying switching request acknowledgement message to DeNB by information back reconstruction corresponding for these communities
System, in some instances it may even be possible to carry in switching request acknowledgement message).After DeNB receives these information, one's own community is believed
Breath retains, and rebuilds the community belonging to other RN information must be transmitted to the RN that these communities are corresponding.
Step 603, if UE is to the handoff failure of Target cell, then UE reselects community and the community chosen is initiated weight
Build.If UE selects to have initiated potential rebuilding community as above to rebuild, then because of the existing UE weight to this community in base station
Build required information, then rebuild and be probably successfully (otherwise inevitable failure).
