Finally, example of the invention further relates to a kind of system, may include the source eNB of above-mentioned example according to the present invention 2021, target eNB 2022 and UE 201.

Fig. 3 shows the data structure 300 for determining hand off signaling scheme of example according to the present invention.

As shown in Figure 3, data structure 300 may include the first signaling schemes of instruction（For example, delta signaling schemes）With Second signaling schemes（For example, complete signaling schemes）One of the information unit 301 used, first and second signaling schemes One of use be based on first protocol version（For example, being for example sent to target eNB with signal during switching preparation The RRC protocol versions of 2021 source eNB 2021）With external second protocol version（For example, configuring target eNB 2022 to The RRC protocol versions supported）It determines.

In addition, the data structure may include optional header 302, optional payload portions 303 and optional Telegram end 304.

With regard to for the relevant exploitation of the data structure, the data structure can be by switching request acknowledgement message structure At.In addition, first signaling schemes can be utilized in radio resource control specification（For example, handover preparation information message）In The radio resource control container of definition.In such a case, it is possible to which described information unit is set as yes affirmative.In addition, In this case, first protocol version（For example, the RRC protocol versions of source eNB 2021）Second protocol version can be higher than This（For example, the RRC protocol versions of target eNB 2022）.Alternatively, the second signaling schemes can be utilized in X2 application protocols Specification（For example, switching request message）Or S1 Application Protocol specification（For example, message needed for switching）Defined in message.This In the case of, described information unit can be set as to non-affirmative.In addition, in this case, first protocol version can be with Equal to or less than second protocol version.However, identical information should be transmitted from source eNB 2021 to target eNB 2022, without How is pipe signaling schemes.In addition, the protocol version can be made of protocol issuance version.In addition, described information unit can be by At least one composition.In addition, the switching request acknowledgement message can be connected by radio resource control reconfigures message structure At, or the message can be encapsulated.In addition, first agreement can be by the radio resource control agreement of switching source entity It constitutes, and the instruction of first protocol version can be cited information unit.In addition, the second protocol can be by cutting The radio resource control agreement for changing target entity is constituted.Finally, complete configuration or the switching command message of delta configurations can It is constituted with reconfiguring message by radio resource control connection, and radio resource control container can be by handover preparation information Message is constituted.

In the case of following details in being not limited to the part, the example of the present invention can be summarized as follows：

For example, if the new channel quality indicator defined in Rel-9（CQI）Report Parameters, and with the sources Rel-9 New CQI report parameter in eNB configures UE, then should issue this new CQI report parameter in switching Give Rel-8 ENB.However, since Rel-8 eNB do not support this functionality, thus it will be unable to discharge this functionality, It cannot 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 used in the eNB of source（Radio 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 UE（User equipment）Target 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 for example in Rel-8 or forward（onwards）In RRC connections reconfigure and disappear 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 pass through its RRC container（For example, handover preparation information Message）Or X1/S1 message（Message needed for switching request message/switching）Indicate 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 identical message（That is switching command message）In One indicator, to which UE can properly configure parameter.
