Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, and below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
The mutual of message is realized by the application layer protocol (S1Application Protocol, S1-AP) between eNodeB and MME between MME and evolution base station (evolved NodeB, eNodeB).
Subscriber equipment (User Equipment, UE) be in the caller process under ECM-CONNECTED (there is Non-Access Stratum signaling link between UE and core net) state, support the flow process of the CSFB that PS switches between MME and eNodeB as shown in Figure 1.
1a, UE allow MME trigger CSFB process by sending expansion service request (Extended Service Requset) message to MME.
1b, MME sends S1-AP UE context modification request (ContextModification Request) message to eNodeB, comprising information element (Information Elements, IE) CSFB Indicator, instruction eNodeB carries out CSFB business.
1c, eNodeB reply S1-AP UE contextual modifications response (ContextModification Response) message to MME.
Now eNodeB may according to the configuration of self, and the CSFB Indicator carried in 1b, selects to perform the CSFB process supporting that PS switches.(eNodeB does not also know the CSFB process whether core net supports PS to switch).
UE is in the caller process under ECM-CONNECTED state, does not support the flow process of the CSFB that PS switches also as shown in Figure 1 between MME and eNodeB.
Difference is, after 1c, eNodeB may according to the configuration of self, and the CSFB Indicator carried in 1b, selects to perform the CSFB process not supporting PS to switch.(eNodeB does not also know the CSFB process whether core net supports PS to switch).
Above-mentioned process description, whether MME carries out CSFB process by S1-AP UE Context Modification Request message informing eNodeB, but only have priority level to indicate inside this message, whether core net does not support the IE of the CSFB that PS switches, and the handoff procedure that eNodeB carries out PS can only lean in advance manually local configuration or attempt carrying out the switching of PS.
UE is in the caller process of ECM-IDLE (there is not Non-Access Stratum signaling link between UE and core net) state, CSFB between MME and eNodeB can multiplexing above-mentioned UE be under ECM-CONNECTED state caller process in flow process, difference is that the S1AP UE Context Modification Request message between MME and eNodeB uses S1-AP initial user equipment context to set up request (Initial UE Context Setup Request) message and substitutes, S1-AP UEContext Modification Response message uses S1-AP initial user equipment context to set up response (Initial UE Context Setup Response) message and substitutes.
It is the same here that the called process of UE carries out CSFB with caller process at triggering eNodeB, is also divided into UE at ECM-IDLE state and UE in ECM-CONNECTED state.UE is under ECM-IDLE state, notify that UE carries out CSFB process by S1-AP Initial UE Context Request message, UE, under ECM-CONNECTED state, is notify that UE carries out CSFB process by UE ContextModification Request message.
Protocol stack between MME and eNodeB is S1 protocol stack, to carry out between MME and eNodeB communicating, S1 link must be set up, in the Establishing process of S1 link, MME and eNodeB needs mutual ability each other mutually, as shown in Figure 2, eNodeB sets up request (Setup Request) message by S1 and the ability of eNodeB is carried to MME, and MME sets up response (Setup Response) message by S1 and the ability of MME itself and configuration data are carried to eNodeB.
If the ability of MME needs to upgrade, then by MME config update (ConfigurationUpdate) message, the ability after renewal is carried to eNodeB, as shown in Figure 3, eNodeB returns MME config update confirmation (Configuration Update Acknowledge) message to MME.
Technical solution of the present invention is not modified to agreement flow process, when considering agreement back compatible, conditionity IE is increased in Initial Context Setup Request message and UE Context Modification Request message---CSFB performance (Capacity), to distinguish the CSFB process whether core net supports PS to switch.
The definition of above-mentioned conditionity IE is as shown in table 1.
The amendment of Initial Context Setup Request message and UE Context Modification Request message structure body, as table 2, with addition of CSFB Capacity IE.
Indicated whether the CSFB supporting that PS switches by CSFB Capacity, only carry in CSFB process, and consider the compatibility of agreement, definition CSFB Capacity is optional IE.
Consider that the ability of core net is the ability of equipment, and the UE relation itself switched little, therefore can increase the CSFB ability whether MME support PS to switch by CSFB Capacity and be carried to eNodeB in S1Setup Response message.
In the completeness considering agreement, and the development of subsequent network, if do not support the CSFB that PS switches before core net, follow-uply to support, needs to inform eNodeB, therefore need to increase CSFB Capacity in MMEConfiguration Update message.
