Description
Technical field
The present invention relates to communication technical field, particularly a kind of method for processing business and equipment.
Background technology
Multimedia priority service is the calling allowing state security department or urgent preparation department user to be used high priority by public network.For this kind of business, even if network is in special state, as congestion state, the transmission of this kind of business also to be ensured.Individual, urgent management organization or other individuals authorized of the user of this kind of business normally government authorization.
The multimedia service of evolution supports IMS (IP Multimedia Subsystem, IP Multimedia System) processed of business, EPS (Evolved Packet System, the evolved packet system) processed of business and the processed of circuit domain business.For eMPS (enhancement forMultimedia Priority Service, the multimedia priority service strengthened) caller or called service, network provides processed end to end, comprise NAS (Non-Access-Stratum, Non-Access Stratum) and AS (Access-Stratum, Access Layer) signaling connection establishment process and core net and wireless network side for the resource allocation process of carrying.
Emergency bearing business is used for the IMS emergent session that provides support, and emergency bearing business may be used for the UE (User Equipment, subscriber equipment) of normal attachment, also may be used for the UE being in unrestricted model state.Even if when UE can not be resident to a suitable cell (suitable community), or UE does not insert SIM (Subscriber Identity Module, user identification module) card, or when UE have received response message (as being designated as " illegal UE ") of some position registration, UE still may initiate emergency bearing business.
LTE (Long Time Evolved, Long Term Evolution) system only provides PS (Packet Switched, packet switching) business, at 2G (2nd Generation, second generation mobile communication system)/3G (3thGeneration, 3-G (Generation Three mobile communication system)) CS (Circuit Switched, circuit switching) business in system cannot directly realize in LTE system.But; for the current operator with the 2G/3G network of large scale deployment; they wish the investment as far as possible protecting its existing network; also need to consider that existing user is to circuit-switched service demand on the other hand; therefore, wish that the LTE multimode terminal of support circuit switched service also can be initiated or the receiving circuit reciprocal exchange of business after being linked into LTE system.
At present, for this problem, in LTE system, introduce CS Fallback (circuit switching rollback) mechanism.The essence of CS Fallback is the multimode terminal residing in LTE network when needing the session of setting up CS territory, and UE return back in the CS territory network of 2G/3G by network.In the whole voice conversation stage, UE is always positioned at CS territory network.After voice service terminates, UE just can turn back in LTE network.
Circuit-switched service can be initiated after UE return back to CS territory, but its packet switching service activated in LTE system then cannot continue to keep in the cs domain.If terminal and rollback system can support the handoff procedure of packet switching, then when there is CS Fallback, the packet switching service carrying that UE can be activated in LTE is switched in the PS territory network of rollback system.If terminal or rollback system do not support the handoff procedure of packet switching, then once there is CS Fallback process, the packet switching service that UE activates will be terminated.
Realizing in process of the present invention, applicant finds that prior art at least exists following problem:
If UE has activated or when being about to an activation high-priority service, if UE has initiated CS Fallback process, then UE must return back in 2G/3G system.If rollback system does not support that PS switches, then once the PS business that after there is CS Fallback, UE activates will be terminated, the high-priority service of activation also will be terminated, and have a strong impact on the continuity of high-priority service.

Accompanying drawing explanation
Fig. 1 is the schematic flow sheet of a kind of method for processing business that the embodiment of the present invention proposes;
The structural representation of a kind of eNB that Fig. 2 proposes for the embodiment of the present invention.
Embodiment
As stated in the Background Art, in LTE system, introduce the high-priority service such as eMPS and IMS emergence call service, compared with general service, network has higher priority when processing eMPS and IMS emergency business, when network be in higher load condition or overload can not keep the connection of general service time, these high-priority service still can normally be linked in network.
In addition, in order to the UE residing in LTE system still can receive CS territory business, in LTE system, introduce CS Fallback mechanism.
After UE initiatively initiates or receives the paging in CS territory, UE will return back to 2G/3G system receiver circuit territory business.If network does not support the PS handoff procedure from source base station to target BS, after CS Fallback, the connection being released in LTE community is reselected to Target cell by UE, and sets up CS territory with Target cell and be connected.Now, UE can only receive the business in CS territory, and can not receive the business in PS territory.
According to foregoing description, if UE has had high-priority service that is that activate or that activating, and now UE has initiated the business in CS territory, or when have received the called of CS territory and be redirected to 2G/3G system, high-priority service will be terminated, and have impact on the continuity of high-priority service.
In order to address this problem, the embodiment of the present invention gives the terminal equipment current high-priority service that whether there is activation or activating that need perform the Indication message of CS Fallback process corresponding to of a kind of eNB according to receiving, and this needs whether the Indication message performing CS Fallback process is that high-priority service triggers, determine whether the method for processing business performing CS Fallback process.
As shown in Figure 1, be the schematic flow sheet of a kind of method for processing business that the embodiment of the present invention proposes, be applied in LTE system, the method specifically comprises the following steps:
Step S101, eNB receive the Indication message needing to perform CS Fallback process that MME sends.
Step S102, eNB judge that the terminal equipment corresponding to Indication message needing to perform CS Fallback process is current and whether there is the high-priority service activating or activating.
If need the current high-priority service that there is not activation or activating of the terminal equipment corresponding to Indication message performing CS Fallback process, perform step S105;
If need the current high-priority service that there is activation or activating of the terminal equipment corresponding to Indication message performing CS Fallback process, perform step S103.
In concrete application scenarios, the concrete processing procedure of this step is:
The ARP information corresponding with terminal equipment that eNB is sent by MME, judges that terminal equipment is current and whether there is the high-priority service activating or activating.
In actual applications, the corresponding information of the business that MME can carry out in the terminal equipment corresponding to eNB sends to eNB, wherein, comprise the ARP information of the business corresponding to terminal equipment, and general service and high-priority service can use different ARP, so according to the particular content of ARP information, eNB directly can determine that this terminal equipment is current and whether there is the high-priority service having activated or activated.
Because ARP information is directly sent to eNB by MME when there being service condition change or have service needed to activate, so, after eNB receives the Indication message needing to perform CS Fallback process, directly according to the current already present ARP information corresponding with this terminal equipment, the current judgement that whether there is the high-priority service activated or activating of this terminal equipment can be carried out.
Step S103, eNB judge whether carry high priority indication information in the Indication message needing to perform CS Fallback process.
If judged result is need to carry high priority indication information in the Indication message of execution CS Fallback process, perform step S105;
If judged result is need not carry high priority indication information in the Indication message of execution CS Fallback process, perform step S104.
The information of the Target cell that the terminal equipment corresponding to Indication message that step S104, eNB perform CS Fallback process as required reports, determines whether to perform CS Fallback process to terminal equipment.
In actual applications, the processing procedure that this step is concrete is as follows:
If now terminal equipment has the high priority carrying of setting up, so network by continued high priority carrying process of establishing after continuous operation after execution; If now terminal equipment has established high priority carrying, then the information of the Target cell that the terminal equipment corresponding to Indication message that eNB performs CS Fallback process as required reports, has judged whether Target cell supports that PS switches.
Such judgement object be to determine that if this terminal equipment performs CS Fallback process, the PS service bearer of the high priority that whether this terminal equipment can have been activated in LTE is switched in the PS territory network of rollback system.
If judged result is for supporting, then eNB performs the Indication message of CS Fallback process as required, performs CS Fallback process to terminal equipment.
If judged result is not for support, then eNB refusal performs CS Fallback process to terminal equipment, thus ensures that the PS service bearer of high priority that is that this terminal equipment activates in LTE or that activate can not be interrupted because of CS Fallback process.
Step S105, eNB perform the Indication message of CS Fallback process as required, perform CS Fallback process to this terminal equipment.
Wherein, in the processing procedure of above each step, high-priority service specifically comprises emergency (promptly) business in CS territory or eMPLL (enhanced Multi-Level Precedence andPreemption, the multipriority of enhancing and take the lead) business.
It is pointed out that and above-mentioned step S104, eNB refusal is specially the operation that this terminal equipment performs CSFallback process:
ENB sends failed Indication message to MME, carries corresponding failure cause indication information in failed Indication message, notice MME, the instruction failure of its execution CS Fallback process initiated;
Wherein, failure cause indication information is specially and there is high-priority service with present terminal equipment and can not carry out the corresponding cause information of CS Fallback process.
Further, in the operation of reality, after eNB have sent unsuccessfully Indication message to MME, also comprise following two kinds of situations:
The triggering reason that what received by situation one, eNB, MME sent need performs the Indication message of CS Fallback process is caused by the business initiated by terminal equipment
MME sends Service Reject (service denial) message to terminal equipment, carries corresponding Reason For Denial indication information in this Service Reject message.
In concrete application scenarios, above-mentioned Reason For Denial indication information is specially CS domaintemporarily not available (CS territory temporarily can not be applied) information, or there is high-priority service with current and can not carry out the corresponding cause information of CS Fallback process.
Wherein, with current to there is high-priority service and can not carry out the corresponding cause information of CS Fallback process can be default a kind of new cause value information; its concrete content can need to set according to the scene of reality, and such change does not affect protection scope of the present invention.
The triggering reason that what received by situation two, eNB, MME sent need performs the Indication message of CS Fallback process is MT CS Fallback or MT 1xCS Fallback process
MME receive eNB send carry the failed Indication message of corresponding failure cause indication information after, MME sends refuse information to MSC, carry corresponding Reason For Denial indication information in refuse information, suspend to make MSC and send to MME the paging request message that common CS territory business triggers.
In concrete application scenarios, Reason For Denial indication information is specially Mobile terminating CSFallback call rejected by the user (calling of MT CS rollback is refused by user) information, or there is high-priority service with present terminal equipment and can not carry out the corresponding cause information of CS Fallback process.
Wherein, with current to there is high-priority service and can not carry out the corresponding cause information of CS Fallback process can be default a kind of new cause value information; its concrete content can need to set according to the scene of reality, and such change does not affect protection scope of the present invention.
It is further noted that; because the interface between eNB and MME is S1 interface; so; what the MME that aforesaid eNB receives sent needs the Indication message performing CS Fallback process; S1 instruction can be presented as in practical application scene; the change of such type of message, can't affect protection scope of the present invention.

Below, in conjunction with concrete enforcement scene, the technical side that the embodiment of the present invention proposes is described in detail.
When eNB receives the S1 message needing execution CS fallback to indicate containing MME transmission, eNB needs to judge that this needs the current high-priority service carrying whether having activation or activating of UE performed corresponding to CS fallback instruction, as eMPS business or IMS urgency traffic etc.
By the value of ARP, eNB can judge whether UE has high-priority service.
If exist, then eNB judges whether this CS fallback process is triggered by high-priority service further, according to corresponding judged result, comprises following two kinds of situations:
If do not carry high priority instruction in situation A S1 message, then the Target cell in the eNB measurement result that can report according to UE determines whether initiating to continue to perform CS Fallback process.
If Target cell supports that PS switches, then eNB continues to perform CS fallback process, if Target cell does not support that PS switches, then eNB returns failed message to MME, and in failed message, carries cause value instruction MME due to now UE and have high-priority service CS territory temporarily unavailable.Return service reject message to UE after MME receives the failed message carrying this instruction, and carry cause#39 instruction " CS domain temporarily not available ".
If now caused by MT business procedure, MME also needs to return paging refuse information to MSC, and indicates " Mobile terminating CS fallback call rejected by the user ".Or use new cause value notice MSC to have high priority PS business CS fallback call temporarily can not use at present due to UE.Will suspend within a period of time after MSC receives this new cause and send to MME the paging request that common CS business causes.
If carry high priority instruction in situation B S1 message, then eNB continues to perform CS fallback process.
