Description
Technical field
The present invention relates to the communications field, method, the Apparatus and system of handling failure in particularly a kind of evolvement network.
Background technology
In the existing evolution network framework and deposited a plurality of wireless access systems (RAT system) with different radio access technologies, consult shown in Figure 1, described evolution network framework comprises and belongs to long-term evolving network (Long-term evolution, LTE) evolution wireless access network (Evolved RAN, E-RAN), belong to System Architecture Evolution network (System Architecture Evolution, SAE) evolution block core net (Evolved Packet Core, EPC), belong to the GPRS core net (GPRS Core) and GSM EDGE wireless access network (the GSM EDGE Radio Access Network that leave over conventional wireless communication systems/GPRS (UMTS/GPRS) network, GERAN) and UMTS (land radio access web UMTS Terrestrial Radio Access Network, UTRAN).
As shown in Figure 1, mobile management entity in EPC (Mobility Management Entity, function MME) is to preserve user's face context of subscriber equipment (UE), as user's sign, mobility management states, tracking area information etc., and UE authenticated; (UserPlane Entity, function UPE) is the downlink data of termination idle condition UE to user entity, triggers paging simultaneously, preserves user's face context of UE, as the IP address of UE and routing iinformation etc.User's face anchor point (InterAS Anchor is the user planeanchor for mobility between different access systems, IASA) be user's face anchor point that the user is linked into Packet Data Network, function with grouping route and forwarding, and finish the policy and charging enforcement function (Policy and Charging Enforcement Function, PCEF) and collecting charging information etc.(Home Subscriber Server HSS) is used for storing user subscription information to home subscriber server.
Based on above-mentioned evolution network framework, when UE is mobile between different RAT system (as UTRAN/GERAN network and the LTE/SAE evolvement network of 2G/3G), UE can be because of being stationed the ping-pong that causes frequent network registration process at different networks, thereby cause the waste of interface-free resources.At this phenomenon, consult shown in Figure 2, under the prior art, when UE moves to RAT2 again and carries out network registry once more after the RAT1 registration, to set up the associated context of a UE between the corresponding network node of two kinds of RAT systems, described associated context comprises the lane place of user ID, casual user sign, UE registration of UE and network node information etc., like this, UE just need not initiate any registration process when mobile again between the registration area (route district RA or tracking area TA etc.) of these two network node correspondences.
In above-mentioned gradual network system, when a certain network node breaks down, the network node of adjacency is found the fault network node by heartbeat message (as the echo detect-message in user's face tunnel between two network nodes, the heart-beat heartbeat message during perhaps SCTP connects etc.); Wherein, the network node of adjacency and fault network node belong to same RAT system, perhaps belong to two kinds of different RAT systems.
When finding the fault network node in evolvement network, the method that prior art is continued to use two kinds of handling failures in the UMTS network solves problem.
First method is: UE is reorientated or is registered in another network node, though make in this way transferring user effectively, but related procedure can only be by the UE triggering that initiatively sends a request message, if before UE initiatively sends a request message, there is the downlink data of UE to arrive, then this downlink data will be dropped, this can cause UE promptly can not do not received business by normal paging.
Second method is: the network node of N work is divided into a backup group, the alternate device that one (or several) are used for disaster tolerance carries out static backup to the data of this group, when certain network node breaks down, the data of alternate device load fault network node are taken over this network node and are carried out work; Though make the normal paging that does not influence UE in this way, owing to need Backup Data, thereby need to reserve certain Internet resources, this will take the network equipment of some, thereby cause the wasting of resources.
By a little as seen, the method for handling failure and be not suitable for evolvement network in the UMTS network, thereby the method that proposes a kind of handling failure of suitable evolvement network has just become the problem of current needs solution.

Embodiment
In the embodiment of the invention, when first network node in the evolvement network determines that second network node breaks down, described first network node carries out corresponding handling process according to the residing wireless access system of second network node, make by this handling process and on described second network node, to set up the contextual user terminal of user's face and nullify from described second network node, wherein, described cancellation comprises user terminal is separated from described second network node, perhaps user terminal is transferred to other network nodes from described second network node.
Below in conjunction with accompanying drawing to a preferred embodiment of the present invention will be described in detail.
Consult shown in Fig. 3 A, in the embodiment of the invention, communication system comprises that (Radio Access Technology, RAT) system are called RAT A and RAT B for 2G/3G network and these two kinds of wireless access technologys of LTE/SAE network.Access network node among the RAT A is called access node a1, access node a2......, core net node among the RAT A is called network node A1, network node A2......, in like manner, access network node among the RAT B is called access node b1, access node b2......, core net node among the RAT B is called network node B1, network node B2......, and in RAT A and RAT B, have shared user's face anchor point, this user's face anchor point may be same physical entity with some network nodes, or physical entity independently.
Consult shown in Fig. 3 B, in the communication system network node (can be network node A1, or network node B1) comprise communication unit, judging unit and processing unit.Described communication unit is used for carrying out information interaction with other network nodes or user terminal; Described judging unit is used for determining that according to heartbeat detection message another network node breaks down; Described processing unit is used for carrying out corresponding handling process according to the residing wireless access system of network node that breaks down, make by this handling process and on the network node of described fault, to set up the information that the contextual user terminal of user's face is deleted this network node, and, perhaps described user terminal is transferred to other network node with of the network node separation of described user terminal from described fault.
Based on the above-mentioned network architecture, in the present embodiment, set up the associated context of certain user terminal (UE) between network node A1 and the network node B1, when network node A1 detects network node B1 and breaks down by heartbeat message, network node A1 obtains the network address of this UE according to the associated context of UE, and to UE initiation separation (Detach) process, pressure separates UE from the wireless access system RAT B at network node B1 place, promptly indicate UE to delete all information relevant with network node B1 in this locality.
Consult shown in Figure 4ly, network node A1 is as follows to the detailed process that UE initiates separation process:
Step 400: network node A1 initiates detach request message to UE, and indication UE separates from RAT B.
Generally, network node A1 can't learn that the wireless access system at the current place of UE is RAT A or RAT B, so network node A1 directly sends detach request message to UE in RAT A; In RAT B, select a network node B2 simultaneously, B2 transmits detach request message to UE by network node, the information that comprises UE self in the described detach request message, user ID, casual user's sign, other UE signature identifications (as the IP address) of comprising UE, and the location area information of UE in RAT B etc.Certainly, if network node A1 can know in advance that the residing wireless access system of UE is RAT A or RATB, then network node A1 can select the described detach request message of a kind of transmission in the above-mentioned dual mode.
If before network node A1 sends detach request message, user's face anchor point receives the downlink data that sends to UE and initiates the data notification request message to network node A1, and then network node A1 also will notify UE to have downlink data to arrive when sending detach request message.
Step 401: network node A1 initiates user's face updating context flow process of UE to user's face anchor point.
In this process, user's face anchor point activates user's face context of the local UE relevant with network node B1 and deletes the information that UE and network node B1 are correlated with in this locality.
Step 402: network node A1 is to home subscriber server (Home Subscriber server, HSS) send the separation Indication message, carry the relevant information of RAT B in this message, network node B1 and the deletion of the related information between the UE that the HSS server is preserved this locality.
On the other hand, network node A1 also will delete the information of network node B1 in this locality.
Step 403:UE separates this UE after receiving the detach request message that is sent by network node A1 from network node B1, UE deletes the relevant information of network node B1 in this locality simultaneously, and returns separation to network node A1 and accept message when end of operation.
UE can accept message with described separation and directly be sent to network node A1, also can be sent to network node B2 earlier, is forwarded to network node A1 by network node B2.
Step 404: if the current place of UE wireless access system is RAT A, then UE is in the information of this locality deletion network node B1 and upgrade self communication context, and receives described downlink data when finding downlink data is arranged; If the wireless access system at the current place of UE is RAT B, the information of UE deletion network node B1 then, and re-register new network node to the RAT B, and upgrade the communication context of self, if find that downlink data is arranged, then receive described downlink data.
Be different from the foregoing description, network node A1 can also initiate heavily to register (Re-RAU/TAU Re-attach) flow process when finding that network node B1 breaks down, and request UE re-registers another network node among the RAT B.Consult shown in Figure 5ly, the detailed process that network node A1 indication UE registers again is as follows:
Step 500: network node A1 sends heavy login request message to UE, and (Re-RAU/Re-TAU, Re-attach), request UE re-registers in another new network node among the RAT B.Equally, network node A1 directly sends heavy login request message to UE, transmit this heavy login request message by the network node B2 among the RAT B simultaneously, user ID, casual user sign and other UE signature identifications (as the IP address) of comprising UE in the described heavy login request message, and UE is in the location area information of this RAT system registry etc.
Step 501: if UE is just quartering at RAT A, then UE replys heavy registration reply message to network node A1 earlier after receiving heavy login request message, send login request message to corresponding network node B again, the described relevant information that includes UE in the heavy registration reply message and whether be registered to RAT B (for example be about to initiate maybe wouldn't initiate heavily register at RAT B etc.) of stating.
If UE is just quartering at RAT B, then UE directly initiates register requirement to network, the network node that UE is registered to may be network node B2, it also may be other network node, promptly transmitting the network node of heavy registration reply message and the network node that UE re-registers can be the consolidated network node, also can be different network nodes.In the present embodiment, the situation that is registered to network node B2 with UE is that example describes.
Step 502: network node B2 obtains the communication context (comprising or multinomial information in MM Context, user's face context and the associated context of UE) of UE to network node A1, and carries out network registry to HSS; In registration process, HSS deletes the related information of UE and network node B1 in this locality, and sends the user signing contract information of UE to network node B2.
Step 503: network node B2 replys registration to UE and receives message, carries casual user's sign that network node B2 distributes in this message.
Step 504:UE replys registration to network node B2 and finishes message.
Step 505:UE initiates user's face updating context flow process between network node A1, network node B2 and user's face anchor point.In this process, UE, network node A1 and user's face anchor point write down the relevant information of network node B2 simultaneously, and network node B2 are in the relevant informations of local record UE in the related information information of this locality deletion UE and network node B1.
When UE found downlink data is arranged, no matter UE was at RATA or RAT B, can receive described downlink data by network node A1 or network node B2.
In addition, network node A1 can also be transferred to UE another network node among the RAT B when finding that network node B1 breaks down.In the present embodiment, network node A1 shifts and can realize by two kinds of methods UE.
First method is: network node A1 selects another network node B2 in RAT B, initiates the casual user by network node B2 and identifies heavy assigning process, and new casual user's sign is sent to UE, shifts to carry out UE.Consult shown in Figure 6ly, the detailed process of described first method is as follows:
Step 600: network node A1 selects another new network node B2 in RAT B, and send the user's transfer request message be used to shift UE to network node B2, comprise user ID (IMSI) and casual user sign (P-TMSI, information such as S-TMSI) in described user's transfer request message.This user's transfer request message can initiatively be initiated by network node A1, also can need initiate when network node B1 transmits the downlink data of UE in network A 1.
Step 601: network node B1 obtains the communication context of UE to network node A1, then set up the associated context of UE on network node B1 and the network node A1, and network node B1 carries out network registry to HSS, in the process of registration, HSS deletes the related information of UE and network node B1 in this locality, and sends the user signing contract information of UE to network node B1.
Step 602: network node B2 returns user's transfer response message to network node A1.
Step 603: network node B2 initiates the casual user and identifies heavy allocation flow, and in this flow process, network node B2 sends to UE with new casual user's sign.
Initiate the contextual more new technological process of user's face of UE between step 604:UE, network node A1, network node B2 and the user's anchor point.More in the new technological process, UE, network node A1 and user's face anchor point write down the relevant information of network node B2 simultaneously, and network node B2 are in the relevant informations of local record UE at the related information of this locality deletion UE and network node B1 at this.
When UE found downlink data is arranged, no matter UE was at RATA or RAT B, can receive described downlink data by network node A1 or network node B2.
Second method is: network node A1 resolves the Temporary Mobile Subscriber Identity of UE, UE is transferred to new network node B2, network node B2 is that UE distributes new signature identification, and the access node b1 in relevant position district (TA/RA) among the notice RATB, between the signature identification that the signature identification and the network node B2 of network node B1 distribution distribute, set up related by this access node b1, if the allocative abilities of described access node b1 can not be set up related between described two kinds of signature identifications, then access node b1 informing network Node B 2 is re-registered in RAT B by network node B2 indication UE.
Consult shown in Figure 7ly, in the present embodiment, the detailed process of described second method is as follows:
Step 700: network node A1 is sent to network node B2 with the communication context of UE.
In described process, network node A1 at first resolves the Temporary Mobile Subscriber Identity of UE, then selects new network node B2 in RAT B, and the communication context of UE is sent to network node B2.
Step 701: network node B2 is that UE distributes new signature identification (being called B2), and notifies the access node b1 in relevant position district among the RATB; By access node b1 between signature identification (being called B1) that network node B1 distributes and B2, set up related.
Step 702: network node B2 informing network node A1 has received the communication context of UE, then sets up the associated context of UE on network node B2 and the network node A1.
Step 703: initiate the contextual more new technological process of UE user's face between network node B2, network node A1 and the user's face anchor point.More in the new technological process, network node A1 and user's face anchor point write down the relevant information of network node B2 simultaneously, and network node B2 are in the relevant informations of local record UE in the related information information of this locality deletion UE and network node B1 at this.
Step 704: network node B2 carries out network registry to obtain the user signing contract information of UE, the related information of HSS between this locality deletion UE and network node B1 to HSS.
If UE is current in RAT A, then UE initiate to insert request message to network node A, and network node A1 return accept message after, upgrade user's face context of this locality, at this moment, UE can the active request business service or has been received the corresponding downstream data.
If UE is current in RAT B, then UE sends to access node b1 and inserts request message, after access node b1 resolves the Temporary Mobile Subscriber Identity of UE, according to the related information between B1 and the B2, described access request message is forwarded to network node B2, and UE upgrades local user's face context receiving after access that network node B2 returns accepts message, at this moment, UE can the active request business service or has been received the corresponding downstream data.
In above-mentioned several embodiment, network node A1 is in (RAT A and RAT B) in the different wireless access systems respectively with network node B1, and when being in another network node A2 among the RAT A together and breaking down with network node A1, if the current UE of having quarters at the lane place (being the user's face context that has UE on the network node A2) of network node A2 correspondence, then network node A1 is transferred to the present networks node with described UE, and the alternate network node A2 provide business service for UE.
Consult shown in Figure 8ly, when downlink data arrived, it is as follows that network node A1 shifts the detailed process of UE:
Step 800: user's face anchor point is received the downlink data of UE,
Step 801: user's face anchor point sends data notification to network node A2, and definite network node A2 can't reply response message.
Step 802: user's face anchor point sends paging request message to network node A1, and this paging request message comprises the user ID (IMSI and/or P-TMSI etc.) of UE and location area information etc.
Step 803: network node A1 sends paging request message in the lane place at UE place to UE, carry the user ID (IMSI and/or P-TMSI etc.) of UE in this message, if network node A1 can't know the Acceditation Area at UE place, paging UE in all lane place of all lane place of the network node pond at network node A2 place correspondence or network node A2 administration then, and have the identify label (IMSI) of UE, casual user's sign that network node A1 distributes etc.
After step 804:UE receives described paging request message, upgrade local casual user's sign, and reply page-response message, carry the information of UE self in this message to network node A1.
Step 805: network node A1 initiates the security authentication process to UE, determines promptly whether UE has the authority of using corresponding business service.
Step 806: after network node A1 receives page-response message, carry out network registry to HSS, during registration, network node A1 sends the position to HSS and upgrades location request message, carries the identification information of UE and the identification information of network node A1 in this message.
Step 807:HSS replys to network node A1 and upgrades the position response message, carries the user signing contract information of UE in this message.
Step 808: network node A1 initiates the contextual more new technological process of UE user's face between UE, network node A1 and user's face anchor point, at this more in the new technological process, UE and user's face anchor point are at the related information of this locality deletion UE and network node A2, the relevant information of record network node A1, and network node A1 is in the relevant information of local record UE.
Step 809: user's face anchor point is transmitted the downlink data that receives to UE.
Consult shown in Figure 9ly, when UE initiatively sent business request information, it is as follows that network node A1 shifts the detailed process of UE:
Step 900:UE initiates business request information through access node b1 to network equipment A2.
Step 901: access node b1 can't be sent to business request information network node A2, and then access node b1 is forwarded to new selected network node A1 with this business request information.
Step 902: network node A1 obtains the identify label (IMSI etc.) of this UE from UE.
Step 903: network node A1 initiates the security authentication process to UE.
Step 904: network node A1 carries out network registry to HSS, and when registration, network node A1 sends to HSS and upgrades location request message, carries the identification information of UE and the identification information of network node A1 in this message; And HSS replys renewal position response message to network node A1, sends the user signing contract information of UE to network node A1.
Step 905: after network node A1 is registered to HSS, accept message, carry casual user's sign of network node A1 in this message to UE answer business.
Step 906:UE initiates the contextual more new technological process of communication, at this more in the new technological process, network node A1 obtains user's face context of UE to user's face anchor point, and UE, access node b1 and user's face anchor point are at the related information of this locality deletion UE and network node A2, the relevant information of record network node A1, and network node A1 is in the relevant information of local record UE.
In sum, in the embodiment of the invention, after user terminal is registered to network, if the network node of adjacency is found the network node of user's registration and is broken down, then the network node user terminal of described adjacency separates from the network node of fault, perhaps user terminal is transferred to another network node from the network node of fault, like this, just the communication context of transferring user terminal effectively, make other network nodes take over described user terminal, make this user terminal can normally initiate operation flow, thereby kept the continuity of customer service, and then promoted user's experience.
