When being not limited to the following details in this part, example of the present invention can be summarized as follows:
Such as, if define new CQI (CQI) Report Parameters in Rel-9, and by the new CQI parameter in the eNB of Rel-9 source, UE being configured, so when switching, this new CQI parameter should being distributed to Rel-8 ENB.But because Rel-8 eNB does not support that this is functional, thus it cannot discharge that this is functional, can not correctly use the UE of described function to interact with continuation.
Therefore, consider how to process switching (HO) at source eNB and target eNB when using such as different protocol versions or issuing version.Substantially, example of the present invention provides a kind of mechanism, in the eNB of source, which kind of RRC(radio resource is adopted to control in order to instruction) protocol version (issue version), and therefore can add new parameter to such as handover preparation information message, and target eNB can determine successfully to complete HO the need of complete signaling or delta signaling based on this, and is indicated to UE.In other words, this means that this designator can inform UE(subscriber equipment) target eNB adopts delta collocation method or complete configuration method, and mean that between the switching preparatory stage, the RRC determined being issued version version is sent to target eNB from source eNB signal, can determine adopt or should adopt which kind of method for target eNB.If target eNB RRC protocol version equals RRC protocol version that source eNB using or than renewal, so can support delta signaling.
In order to adopt complete signaling, the RRC proposed such as at Rel-8 or forward (onwards) connects to reconfigure in message and comprises a such as indicating bit.Thus, when " complete signalling indicator " is set as "Yes", UE can know clearly that described RRC connects and reconfigure message not based on delta signaling.Due to this complete signaling may be needed when RRC protocol issuance version higher than target eNB of the RRC protocol issuance version of source eNB, thus Rel-8 forward in there is " complete signalling indicator " can address this problem.
In order to determine whether described " complete signalling indicator " should be set as "Yes", target eNB can such as be made decision between the HO preparatory stage, because this information unit can be made such as to be included in RRC connection reconfigure in message, or it such as can be sent to source eNB with switching request acknowledgement message.
In other words, propose source eNB and can switch the issue version to the RRC agreement of target eNB instruction source eNB between the preparatory stage.Can be included in RRC container, or by X2 and/or S1 in X2 and/or S1 Application Protocol, it can be sent with signal.After target eNB recognizes the RRC protocol issuance version that source eNB is using, and if the issue version that described issue version is using higher than target eNB, or target eNB does not understand described issue version (such as, because source eNB RRC protocol issuance version designator is supported higher than target eNB), so target eNB can adopt complete signaling.If source eNB RRC protocol issuance version is less than or equal to target eNB RRC protocol issuance version, so eNB can adopt so-called delta signaling.
In other words, the signaling of the first protocol version such as can be performed by RRC container or X1/S1 message.Described signaling itself may have nothing to do with delta signaling or complete signaling.Source eNB can by its RRC container (such as, handover preparation information message) or X1/S1 message (the required message of handover request message/switching) instruction such as its RRC protocol issuance version.And described RRC container little by little can be encapsulated in X1/S2 message.Thus, described switching command can be RRC information, and described switching request acknowledgement message can be X2 message.Described switching command message described switching command can be encapsulated in switching request acknowledgement message, and described switching command can be sent to UE by described source eNB, because can have the form that described UE can process.Finally, complete/delta signaling can be relevant with this switching command message, and described switching command message builds in target eNB, and be sent to UE by source eNB.Therefore, a designator in identical message (i.e. switching command message) can be adopted, thus UE can correctly configuration parameter.
