Abstract
本发明公开了一种跨基站RRC连接重建方法及系统，上述方法在目标基站收到UE上报的RRC Connection Re-establishment Request消息后，向MME请求上述UE的上下文；MME将目标基站的请求传递给UE所属的源基站，并将源基站返回的上下文传递给目标基站；目标基站收到UE的上下文后，通知UE进行RRC连接重建，并在UE完成RRC连接重建后，为UE分配物理资源，通知UE进行RRC资源重配。本发明使得目标小区与源小区异基站的情况下，UE侧的应用层业务扔可正常完成接续，缩短了业务中断时间，提高了用户体验。
The invention discloses a cross-base station RRC connection re-establishment method and system. After the target base station receives the RRC Connection Re-establishment Request message reported by the UE, the method requests the context of the UE from the MME; the MME passes the request of the target base station to the The source base station to which the UE belongs, and transfers the context returned by the source base station to the target base station; after receiving the context of the UE, the target base station notifies the UE to perform RRC connection re-establishment, and after the UE completes the RRC connection re-establishment, allocates physical resources for the UE, and notifies The UE performs RRC resource reconfiguration. In the present invention, when the base station of the target cell and the source cell are different, the application layer service on the UE side can normally complete the connection, shortens the service interruption time, and improves user experience.
Description
Technical field
The present invention relates to the 4th third-generation mobile communication LTE (the Long Term Evolution of the communications field, Long Term Evolution) system, relate in particular to a kind of across base station RRC (Radio Resource Control, Radio Resource is controlled) connection reconstruction method and system.
Background technology
In 3GPP TS 36.331, RRC connection reconstruction flow process has been carried out clear and definite definition,, will initiate RRC and rebuild request when satisfying following condition when terminal (UE):
Radio Link Failure detected;
The intra-system handover failure;
The intersystem handover failure;
The integrity checking failure;
The RRC reconfiguration failure.
when UE detect satisfy above-mentioned condition after, to carry out cell search process, reselect persistent district (being Target cell) with initiating random access procedure, random successfully backward resident base station (being target BS) transmission RRC Connection Re-establishment Request message that accesses, the indicating target base station is that UE redistributes physical resource, and carry PCI (the Physical Cell Identity of cell-of-origin (being the resident residential quarter of UE before RRC rebuilds) in described message, Physical Cell Identifier), the UE sign, rebuild the information such as reason.
The RRC of protocol definition rebuilds flow process and comprises that RRC rebuilds normal flow and abnormal flow process.In actual applications, UE is carrying out the residential quarter when selecting, the Target cell of selection may with cobasis station, cell-of-origin, also may different base station.Under the scene at Target cell and cobasis station, cell-of-origin, Target cell can obtain UE in the communication context information of cell-of-origin, is successfully completed the RRC process of reconstruction; Under the scene of the different base station of Target cell and cell-of-origin, Target cell can't obtain UE in the communication context information of cell-of-origin, therefore can't complete normal RRC process of reconstruction, can only send the reestablishment rejected message of RRC to UE, and UE discharges RRC and connects.
For cobasis station scene, UE side application layer business is complete connection normally, and service outage duration is shorter.For different base station scene, connect because base station side discharges RRC fully, cause UE need to base station side initiating business request process again, again assign business by core net, could continue by finishing service, the application layer business continuing time is longer, affect the user and experiences.
Summary of the invention
The objective of the invention is, provide a kind of across base station RRC connection reconstruction method and system, to solve prior art in the situation that Target cell and small difference base station, source, the problem that can only continue by the ability of UE initiating business request again finishing service.
The invention provides a kind ofly across base station wireless resource control RRC connection reconstruction method, said method is:
After target BS is received the RRC Connection Re-establishment Request message that terminal UE reports, to the context of the above-mentioned UE of MME (mobile management entity) request of core net;
Above-mentioned MME passes to source base station under above-mentioned UE with the request of above-mentioned target BS, and the context transfer that above-mentioned source base station is returned is to above-mentioned target BS;
After above-mentioned target BS is received the context of above-mentioned UE, notify above-mentioned UE to carry out the RRC connection reconstruction;
After above-mentioned UE completed the RRC connection reconstruction, above-mentioned target BS was that above-mentioned UE distributes physical resource, and notifies above-mentioned UE to carry out RRC resource reprovision.
The present invention further provides and a kind ofly comprised target BS, MME and source base station across base station RRC connection reconstruction system,
Above-mentioned target BS is used for when receiving the RRC Connection Re-establishment Request message that UE reports, by the context of UE Context Switch Request message to the above-mentioned UE of above-mentioned MME request; And after receiving the context of above-mentioned UE, notify above-mentioned UE to carry out the RRC connection reconstruction; After above-mentioned UE completes the RRC connection reconstruction, for above-mentioned UE distributes physical resource, and notify above-mentioned UE to carry out RRC resource reprovision;
Above-mentioned MME, be used for by UE Context Switch Request Forward message, the contextual UE Context of above-mentioned target base station requests UE Switch Request message being passed to source base station under above-mentioned UE, and the context transfer that above-mentioned source base station is returned is to above-mentioned target BS;
Above-mentioned source base station is used for by Handover Required message, the context of above-mentioned UE being sent to above-mentioned MME.
The target BS of the present invention by receiving RRC Connection Re-establishment Request message initiated reorientation flow process based on the S1 mouth to the source base station of preserving the UE contextual information, and after receiving the contextual information that source base station returns, complete RRC in the target BS side and connect the RRC connection reconstruction that the reprovision process realizes UE, make in the situation of the different base station of Target cell and cell-of-origin, the application layer business of UE side is thrown away normally complete connection, shorten service outage duration, improved user's experience.
