It can correctly interact with the UE for being continuing with the function.
Accordingly, it is considered to be cut how source eNB and target eNB is handled when using for example different protocol version or release
It changes (HO).Substantially, example of the invention provides a kind of mechanism, to indicate which kind of RRC (radio used in the eNB of source
Resources control) protocol version (release), and therefore new parameter can be added to such as handover preparation information message, and
Target eNB can be able to decide whether that complete signaling or delta signalings is needed to successfully complete HO based on this, and be referred to
Show to UE.In other words, it means that this indicator can inform that UE (user equipment) targets eNB is to use the configuration sides delta
Method or complete configuration method, and mean switch prepare during by determining RRC releases version from source eNB signals
It is sent to target eNB, can determine which kind of method used or should use for target eNB.If target eNB RRC agreements
Version is equal to source eNB RRC protocol versions currently in use or compared with update, then delta signalings can be supported.
In order to use complete signaling, propose that for example the RRC connections in (onwards) reconfigure and disappear in Rel-8 or forward
It include a such as indicating bit in breath.Thus, in the case where " complete signalling indicator " is set as "Yes", UE can understand
Know that the RRC connections reconfigure message not based on delta signalings in ground.Due to the RRC protocol issuance versions in source eNB
May need this complete signaling when RRC protocol issuance versions higher than target eNB, thus Rel-8 forward in there is " complete letter
Enable indicator " it can solve the problems, such as this.
Described in deciding whether to incite somebody to action " complete signalling indicator " is set as "Yes", and target eNB can be for example in HO
It makes decision during preparation, because this information unit can be made for example to be reconfigured in message included in RRC connections, Huo Zheke
It is for example sent to source eNB with switching request acknowledgement message.
In other words, it is proposed that source eNB can indicate the publication of the RRC agreements of source eNB during switching preparation to target eNB
Version.Can be contained in RRC containers, or can by X2 in X2 and/or S1 Application Protocol and/or S1 to it with believing
Number send.After target eNB recognizes source eNB RRC protocol issuances versions currently in use, and if the release is higher than
Target eNB releases currently in use or target eNB do not understand the release (for example, since source eNB RRC agreements are sent out
What cloth version indicator was supported higher than target eNB), then complete signaling may be used in target eNB.If source eNB RRC agreements
Release is less than or equal to target eNB RRC protocol issuance versions, then so-called delta signalings may be used in eNB.
In other words, the signaling of the first protocol version can be for example executed by RRC containers or X1/S1 message.The letter
Order itself may be unrelated with delta signalings or complete signaling.Source eNB can be by its RRC container (for example, handover preparation information
Message) or X1/S1 message (message needed for switching request message/switching) instruction such as its RRC protocol issuance version.And it can be with
The RRC containers are gradually encapsulated in X1/S2 message.Thus, the switching command can be RRC information, and described
Switching request acknowledgement message can be X2 message.The switching command can be encapsulated in switching request acknowledgement message, and
The switching command can be sent to UE by the source eNB, because the switching command message can have the UE that can locate
The form of reason.Finally, complete/delta signalings can be related with the switching command message, and the switching command message is in target
It is built in eNB, and UE is sent to by source eNB.It is therefore possible to use in identical message (i.e. switching command message)
One indicator, to which UE can properly configure parameter.
