Embodiment two
The embodiment of the invention two provides the method for switching between a kind of system, switching to the UTRAN system with UE by E-UTRAN (Evolved Universal Terrestrial Radio Access Network, the universal land radio access web of evolution) system is that example describes.
Suppose a bimodulus UE in the E-UTRAN system, in its moving process, satisfied the condition that switches to the UTRAN system, by source eNB (evolved NodeB, the base station of evolution) sends handoff request message by corresponding core net node to Target RNC, Target RNC sends switching request acknowledgement message to source eNB after receiving handoff request, has carried multicarrier or many cell configuration in this switching request acknowledgement message.In E-UTRAN and UTRAN system, represent the base station with eNB, corresponding with user UE.Source eNB sends switching command according to switching request acknowledgement message to UE, and UE finishes after the access of Target RNC, sends handoff completion message to Target RNC, and whole handoff procedure is finished.Switch UE can be in Target RNC on-line operation in multicarrier (TDD) or many sub-districts (FDD) pattern, for UE provides the higher data transmission rate.
Concrete, shown in Fig. 2 B, this method may further comprise the steps:
Concrete, source eNB is according to ability, the data rate of UE, and information such as the adjacent system version in adjacent sub-district send to UE measures configuration.For example UE supports bimodulus, the support multi-carrier mode, and message transmission rate is higher, and the adjacent system in adjacent sub-district also supports multicarrier, and then the measurement of source eNB configuration need be considered the metrical information of other carrier waves of acquisition destination node.
Concrete, can carry following one or more information in the handoff request message that source eNB sends:

B, source eNB carry necessary UE multi-carrier capability information in mailing to the handoff request message of Target RNC, for example whether support multicarrier or many sub-districts, the frequency point information of support etc.;
C, source eNB select other carrier waves of this destination node that measurement result satisfies condition in the frequency range that this UE supports, and the label information or the frequency point information of other carrier waves is included in the handoff request message that mails to Target RNC; For example, candidate cell or frequency list information are carried in the handoff request message send to Target RNC;
D, source eNB are included in label information or the frequency point information of measurement result by other carrier waves of this destination node of descending in the handoff request message that mails to Target RNC in the frequency range that this UE supports; Descending only is a kind of specific implementation, can also be other arrangement modes, and the embodiment of the invention does not limit this.
E, source eNB are included in the handoff request message that mails to Target RNC through the measurement result of other carrier waves of this destination node in the frequency range that this UE supports.
The condition that measurement result satisfies in the above-mentioned option can be provided with according to actual needs, for example is set to signal strength threshold, and promptly the measurement result of signal strength signal intensity more than threshold value belongs to and satisfy condition.
Source eNB mails to Target RNC with handoff request message by core net node.
Concrete, Target RNC can but be not limited to distribute multicarrier/many cell configuration for switching UE according to following manner:
1), according to the ability information of the UE that carries in the handoff request message and/or the metrical information of other carrier waves of this node (being Target RNC), and the service rate requirement of UE, the occupation condition of self node etc. are to switch UE to distribute suitable multicarrier/many cell configuration;
2), according to other carrier informations that carry in the handoff request message, require and the occupation condition of self node etc. in conjunction with the UE service rate, in carrier list, distribute suitable multicarrier/many cell configuration for switching UE;
3), according to other carrier informations that carry in the handoff request message and order, require and the occupation condition of self node etc. in conjunction with the UE service rate, in listed carrier list, distribute suitable multicarrier/many cell configuration for switching UE;
4), according to the measurement result of carrying in the handoff request message, require and the occupation condition of self node etc. in conjunction with the UE service rate, the carrier wave that satisfies condition is chosen as multicarrier/many sub-districts of UE, and generates the configuration information of these carrier wave/sub-districts.
Switch finish after, source eNB deletes information such as the resource of this UE and context.Target RNC admits the switching of UE to finish order, directly communicates in multicarrier/many sub-districts and UE.
Wherein, before switching, UE need report the ability information of self to source eNB, and for example whether UE supports UTRAN TDD or FDD, whether supports multicarrier, and whether the frequency point information of support is supported to the switching of the PS of UTRAN multicarrier etc.
Wherein, the concrete form of Handover to UTRAN Command is as shown in table 1.
Table 1
