Embodiment
In order to solve in prior art AAA client and aaa server, carry out when mutual, if there is transmission fault between DRA and aaa server, the DRA of unreachable aaa server repeats to receive the message that mails to aaa server, or other DRA repeat to send to the DRA of unreachable aaa server the impact that message may cause signaling network, and the embodiment of the present invention provides a kind of route messages transmission method.
Below in conjunction with accompanying drawing, the preferred embodiment of the present invention is elaborated.
Consult shown in Fig. 2, in the embodiment of the present invention, the detailed process of DRA message transfer is as follows:
Embodiment mono-:
Here, a DRA and the 2nd DRA can be positioned at same group, and by C link connection, or the 2nd DRA is positioned at last group of a DRA.
Wherein, when a DRA is that the 2nd DRA can only be for being positioned at same layer with a DRA with aaa server or when with the direct-connected DRA of AAA client, and by the link-attached DRA of C, in Fig. 1, when a DRA is the DRA in direct-connected DRA group, the 2nd DRA is also the DRA in direct-connected DRA group; When a DRA is the DRA in last DRA group, the 2nd DRA is the DRA in direct-connected DRA group.
Here, according to the type of the first route messages, upgrade unreachable node group information, comprising: if the first route messages is routing failure message, the 2nd DRA information is added to unreachable node group information.If the first route messages is route request information, keep unreachable node group Information invariability.The renewal of unreachable node group information in the embodiment of the present invention, is a kind of renewal of broad sense, keeps unreachable node group Information invariability, also belongs to a kind of renewal.
Here, if the first route messages, not through the 3rd DRA, sends the route request information that comprises the unreachable node group information after renewal to the 3rd DRA.
Here, when a DRA is during with AAA client or the direct-connected DRA of aaa server, the one DRA sends the secondary route message that comprises the unreachable node group information after renewal to AAA client or aaa server, when notifying AAA client to send route messages without the node of unreachable node group after upgrading.
Each node in unreachable node group in the embodiment of the present invention is unreachable to AAA client or aaa server route.
In the embodiment of the present invention, route request information has multiple, preferably, can be ULR message, or be CLR(Cancel-Location-Request, canceling position registration request) message or be AIR(Authentication-Information-Request, authentication request) message can also be the multiple message being mentioned to below:
For example, the ULA(Update-Location-Answer of S6a/S6d interface) message, CLR message, CLA(Cancel-Location-Answer, canceling position register response) message, AIR message, AIA(Authentication-Information-Answer, authentication request response) message, IDR(Insert-Subscriber-Data-Request, inserts user data requests) message, IDA(Insert-Subscriber-Data-Answer, inserts user data) message, DSR(Delete-Subscriber-Data-Request, deletes user data requests) message, DSA(Delete-Subscriber-Data-Answer, deletes user data response) message, PUR(Purge-UE-Request, removes user equipment requests) message, PUA(Purge-UE-Answer, removes user device responsive) message, RSR(Reset-Request, the request of resetting) message, RSA(Reset-Answer, the response of resetting) message, NOR(Notify-Request, notice request) message, NOA(Notify-Answer, push-notification-answer) message etc.
Again for example, the ECR(ME-Identity-Check-Request of S13/S13' interface, mobile equipment identity inspection request), ECA(ME-Identity-Check-Answer, mobile equipment identity inspection response) message, etc.
Also for example, Gx (PCEF-PCRF), Gz/Rf (PGW-OFCF/CSCF-OFCF/AF-OFCF, wherein, PGW:(PDN Gateway, PDN(Packet Data Network, Packet Data Network) gateway), OFCF(Offline Charging Function, offline charging function), AF(application function, Application Function), OCS(online charging system, Online Charging System), OCF(Online Charging Function, online charging function), IP-SM-GW(IP shortmessage gateway, IP short messaging gateway), Gy/Ro (PGW-OCS/CSCF-OCF/AF-OCF), Cx/Dx (CSCF-HSS), series message in Sh/Dh (AF-HSS/IP-SM-GW-HSS), at this, describe in detail no longer one by one.
The message of take below based on Diameter describes as ULA message as example.
In actual applications, the form of ULA message is as follows:
In the embodiment of the present invention, unreachable node group information exchange is crossed AVP field newly-increased in the first message based on Diameter and is carried.
Owing to having carried unreachable node group information in route messages, while making follow-up transmission route messages without the node of unreachable node group, if solved the DRA that has at least one unreachable aaa server in prior art between AAA client and aaa server, other DRA still send the problems such as network storm that message may cause signaling network, network element traffic overload to those inaccessible DRA.
In order to understand better the embodiment of the present invention, below provide concrete application scenarios, for the process of DRA message transfer, make and describing in further detail, wherein, AAA client is MME, and aaa server is HSS, and mutual message is between the two ULR and ULA:
Embodiment bis-: have two DRA groups (specifically as shown in Figure 3):
Step 300:UE roams into after MME, under open state, to MME, initiates to upgrade indication, makes MME launch position upgrade;
In step 300, upgrade indication and can adhere to indication, Detach Request attachment removal indication for Attach Request, or any one in indicating of TAU Request TA.
Step 310:MME selects DRA2-a in the 2nd DRA group, and sends ULR message to DRA2-a;
In this step, when MME selects DRA from the 2nd DRA group, can adopt polling to select, also can adopt the mode in cycle to select.
Step 320:DRA2-a is forwarded to direct-connected DRA1-a in a DRA group by the ULR message receiving;
Step 330:DRA1-a is unreachable to direct-connected HSS, so issue the DRA1-b in same group by C link;
Step 340:DRA1-b is also unreachable to HSS, so DRA1-b returns to ULA message to DRA1-a, notice DRA1-a be positioned at same group, by the unreachable HSS of the link-attached DRA1-b of C, wherein, this ULA message is routing failure message, therefore, DRA1-a can determine according to the ULA message receiving the information of the unreachable HSS of DRA1-b;
Step 350:DRA1-a determines that according to the ULA message receiving DRA1-b can not be sent to HSS by ULR message, (own all routes all can not be sent to HSS by ULR message), DRA1-a returns to the first route messages to DRA2-a, be ULA message, wherein, this ULA message is carried the information of the DRA1-b of the unreachable HSS in the backward direction of DRA1-a; When if to belong to the DRA of same group be a plurality of with DRA1-a, ULA message is carried the information of the DRA group of the unreachable HSS in the backward direction of DRA1-a.
In this step, DRA1-a adds DRA1-b sign to return ULA message, this sign is to carry by the newly-increased AVP field in ULA message, here, in unreachable node group, only comprise a nodal information, be DRA1-b, therefore, DRA2-a determines the unreachable HSS of DRA1-b according to the nodal information carrying in the ULA message receiving, the first route messages receiving due to DRA2-a, be that ULA message is routing failure message, therefore, DRA2-a determines the unreachable HSS of DRA1-a, and the ULA message receiving is upgraded and is sent to DRA2-b, be specially the information of DRA1-a is added in the unreachable node group information receiving.
Step 360:DRA2-a determines that DRA1-b and DRA1-a all can not be sent to HSS by ULR message, that is to say and determined that the DRA of the last group of DRA that is arranged in DRA2-a is all unreachable, carry out route reselection, by ULR message be sent to be positioned at same group pass through the link-attached DRA2-b of C;
In this step, DRA2-a knows that according to the ULA message receiving this message is routing failure message, the sign of DRA1-a is added in the ULR message receiving, and this sign is to carry by the newly-increased AVP field in ULR message.
Step 370:DRA2-b finds oneself without route, can walk by the DRA1-a that carries in the ULR message receiving and the sign of DRA1-b, so return to ULA message to DRA2-a;
In this step, this ULA message is carried DIAMETER_UNABLE_TO_DELIVER information, due to because not have study to arrive new routing iinformation, do not need to carry newly-increased AVP, because DRA2-b just can determine all unreachable HSS of DRA1-a and DRA1-b by the DRA1-a that carries in the ULR message receiving and the sign of DRA1-b, therefore, DRA2-b no longer sends message to ask DRA1-a or DRA1-b that message is sent to HSS to DRA1-a or DRA1-b, and DRA1-a and DRA1-b can not receive the message that DRA2-b sends again yet.And DRA2-b is routing failure message at the first route messages sending to DRA2-a, therefore, DRA2-a is added to the information of DRA2-b in unreachable node group information.
Step 380:DRA2-a determines that DRA1-b, DRA1-a and DRA2-b all can not be sent to HSS by ULR message, and DRA2-a finds oneself without route, can walk, so return to ULA message to MME.In this step, this ULA message is carried DIAMETER_UNABLE_TO_DELIVER information, and DRA2-a adds the sign of DRA1-b, DRA2-b, DRA2-b in the ULA message of returning, and those signs are to carry by the newly-increased AVP field in ULA message.
In this embodiment, MME determines that according to the ULR message receiving DRA1-b, DRA1-a, DRA2-b and DRA2-a all can not be sent to HSS by ULR message, finds without route, can use, and no longer retransmits ULR message, therefore, network element load load and network storm have been avoided.
Embodiment tri-: have three DRA groups (specifically as shown in Figure 4):
Step 4000:UE roams into after MME, under open state, to MME launch position, upgrades indication, makes MME send ULR;
In step 4000, upgrade indication and can adhere to indication, Detach Request attachment removal indication for Attach Request, or any one in indicating of TAU Request TA.
Step 4100:MME selects DRA3-a in the 3rd DRA group, and sends ULR message to DRA3-a;
In this step, when MME selects DRA from the 3rd DRA group, can adopt polling to select, also can adopt the mode in cycle to select.
Step 4200:DRA3-a is forwarded to direct-connected DRA2-a in the 2nd DRA group by the ULR message receiving;
Step 4300:DRA2-a is forwarded to the ULR message receiving the DRA1-a of home domain direct-connected in the one DRA group;
Step 4400:DRA1-a is unreachable to direct-connected HSS, then issue in same group, by the link-attached DRA1-b of C;
Step 4500:DRA1-b is also unreachable to HSS, so return to ULA message to DRA1-a;
In this step, the ULA message that DRA1-a receives is routing failure message, therefore, determine that DRA1-b is unreachable to HSS, the following information being specially by carrying in ULA message determines that DRA1-b is unreachable to HSS: DIAMETER_UNABLE_TO_DELIVER information.
Step 4600:DRA1-a determines that according to the ULA message receiving DRA1-b can not be sent to HSS by ULR message, (own all routes all can not be sent to HSS by ULR message), and DRA1-a returns to ULA message to DRA2-a;
In this step, DIAMETER_UNABLE_TO_DELIVER information is carried in this ULA message, and DRA1-a upgrades the ULA message receiving, be specially the information of DRA1-b is added in the unreachable node group information receiving, this sign is to carry by the newly-increased AVP field in ULA message, DRA2-a determines the unreachable HSS of DRA1-b according to the field of carrying in the ULA message receiving, according to the ULA message receiving, be routing failure message, therefore, determine the unreachable HSS of DRA1-a.
Step 4700:DRA2-a determines that DRA1-b and DRA1-a all can not be sent to HSS by ULR message, carries out route reselection, selects C chain, and ULR message is sent to DRA2-b;
In this step, DRA2-a adds the sign of DRA1-a to the first route messages receiving, be in ULR message, above-mentioned sign is to carry by the newly-increased AVP field in ULR message, DRA2-b determines all unreachable HSS of DRA1-b and DRA1-a according to the message that receives, and DRA2-b is to DRA1-b and DRA1-a transmission ULR message.
Step 4800:DRA2-b finds oneself without route, can walk by the DRA1-a that carries in the ULR message receiving and the sign of DRA1-b, so return to ULA message to DRA2-a;
Wherein, this ULA message is carried DIAMETER_UNABLE_TO_DELIVER information, and this message is routing failure message, due to because there is no study to new routing iinformation, does not need to carry newly-increased AVP.
Step 4900:DRA2-a determines that DRA1-b, DRA1-a and DRA2-b all can not be sent to HSS by ULR message, and DRA2-a finds ownly without route, can to walk, so return to secondary route message to DRA3-a, i.e. ULA message;
In this step, this ULA message is carried DIAMETER_UNABLE_TO_DELIVER information, and DRA2-a also adds the sign of DRA1-b, DRA1-a, DRA2-b to the ULA message of returning, and those signs are all to carry by the newly-increased AVP field in ULA message.
Step 4110:DRA3-a determines that DRA1-b, DRA1-a, DRA2-b, DRA2-a all can not be sent to HSS by ULR message, carries out route reselection, selects C chain, and this ULR message is sent to DRA3-b;
In this step, the secondary route message that DRA3-a receives is routing failure message, therefore, the secondary route message receiving is changed, be specially the information of DRA2-a is added in unreachable node group information, the information of DRA2-a is to carry by the newly-increased AVP field in ULR message.
Step 4120:DRA3-b finds oneself without route, can walk, then to DRA3-a, return to ULA message, wherein, this ULA message is carried DIAMETER_UNABLE_TO_DELIVER information, for routing failure message, due to because there is no study to new routing iinformation, do not need to carry newly-increased AVP;
Step 4130:DRA3-a determines that DRA1-b, DRA1-a, DRA2-b, DRA2-a and DRA3-b all can not be sent to HSS by ULR message, and DRA3-a finds oneself without route, can walk, so return to ULA message to MME.
In this step, this ULA message is carried DIAMETER_UNABLE_TO_DELIVER information, DRA3-a also adds the sign of DRA1-b, DRA1-a, DRA3-b, DRA3-a and DRA3-b to the ULA message of returning, and those signs are to carry by the newly-increased AVP field in ULA message.
In this embodiment: MME determines that DRA1-b, DRA1-a, DRA3-b, DRA3-a, DRA2-a and DRA2-b all can not be sent to HSS by ULR message, find without route, can use, no longer retransmit ULR message.
In embodiment bis-and embodiment tri-, take and send ULR message as example between MME and HSS, avoided DRA to repeat to send the impact that ULR message causes signaling network, and then avoid aaa server and AAA client to carry out when mutual, if the unreachable aaa server of DRA, DRA repeats to send the impact that this message causes signaling network.
