From above-mentioned example, the changing method that the present invention is based on carrier aggregation is divided into two large implementation phases: handoff preparation phase and handover execution stage.Below two implementation phases are summarized explanation:
Handoff preparation phase, content is mainly as follows:
LTE system broadcast basic parameter is set, ensures that SeNB selects Cell1-1 as the PCell of all UE under this base station in Cell1-1, Cell1-2, Cell1-3, and specify PCell to be scheduling carrier wave; LTE system broadcast basic parameter is set, ensures that TeNB selects Cell2-1 as the PCell of all UE under this base station in Cell2-1, Cell2-2, Cell2-3), and specify PCell to be scheduling carrier wave; Arrange LTE system broadcast basic parameter, be then only used for as SCell by other Cell, under responsible corresponding PCell, the data dispatch of UE, does not allow UE to carry out selecting or this community of gravity treatment; Each community is set up and is activated successfully, respectively by the reserved resource of the UE rank of SCell dispensed, and notifies that PCell preserves, and object is the SCell resource can directly learnt on PCell under this base station;
Further, base station SeNB and TeNB can draw neighboring BS relationship and adjacent area parameter by X2 link, and sets up base station Neighboring Cell List with this, and also indicating which community in the Neighboring Cell List of base station is the PCell community specified under adjacent base station, and which is SCell community.
PCell under SeNB and TeNB of base station records the broadcast message of its lower SCell separately respectively, is mainly used in the SCell resource information of configuration UE.Object directly to learn the resource of SCell on PCell, need not wait for that SCell returns results.UE can only select Cell1-1 community to access under SeNB base station, and using Cell1-1 as its PCell, only for scheduling carrier wave, the resource taken is little, can increase throughput of system; Select Cell1-2 and Cell1-3 as its SCell simultaneously, carry out transfer of data, the data throughout of UE can be increased, improve UE peak rate.
Handover execution stage, content is mainly as follows:
Along with UE moves to TeNB coverage, source base station SeNB can receive the covering measurement report of UE, when determining that need carry out base station switches, triggers UE and switches.
During source base station SeNB select target community, if the Target cell of initial option is the SCell of TeNB, then according to neighboring station information change Target cell, the PCell only under selection TeNB is as Target cell; Source base station SeNB, also according to the SCell list of TeNB, selects to exist only in the community alternatively SCell in the covering measurement report that UE reports, and measurement result is sent to target BS TeNB together with candidate SCell; SCell information under present for UE SeNB also can be sent to target BS TeNB by source base station SeNB.Concrete, the SCell configuration information that UE is using directly can be obtained in the PCell of SeNB;
The candidate SCell that the PCell of Target Station TeNB provides according to source station, select to have reserved resource as target SCell, and directly take out the reserved resource of the target SCell stored from the PCell of TeNB.Also can distribute new reserved resource and be supplied to other UE and use by request target SCell simultaneously;
UE carries out carrier aggregation switching according to the target SCell selected and SCell to be deleted.UE can only select Cell2-1 to access under TeNB, and using Cell2-2 and Cell2-3 as SCell, only for transmitting data information.If switching achievement, after the PCell of TeNB receives the handover success message that UE sends, notice MME handover success, MME reinforms source base station SeNB and discharges all resources of this UE in SeNB base station side, comprises PCell and the SCell resource that this UE uses under SeNB base station.If after this handoff failure, also without the need to reclaiming the reserved resource of SCell, this resource directly can be kept for other to switch subscriber equipment and use, and reclaims until the reserved number of resources of SCell exceedes setting quantity again, object is the operation of minimizing system, elevator system performance.
