Description
Technical field
The present invention relates to the communications field, particularly a kind of processing method of containing parameter message and system, equipment.
Background technology
In existing network communication, each network node is in message construction, because information is not enough, the node receiving message is difficult to correct judgement to the parameter in message and how operates, as intermediate node receive starting node send message in parameter after, do not know it is in this parameter of processing locality, still send it to other node.Be that example is described with the tunnel management messages transmission of GTP (GPRSTunnelingProtocol, GPRS Tunnel Protocol) v2 below.
Fig. 1 is that the tunnel management messages of GTPv2 transmits schematic diagram, as shown in the figure, in current EPS (data network system of evolution) system, all exist by MME (MobilityManagementEntity, Mobility Management Entity) or SGSN (ServingGPRSSupportNode in a lot of session management flow process; Serving GPRS Support Node) be sent to S-GW (ServiceGateway, gateway) message, such administrative messag sends to P-GW (PDNGW again after S-GW process, PackedDataNetworkGateway, grouped data network gateway), it is do not need S-GW to send to P-GW that the parameter in these administrative messags has a kind of; The parameter that another kind needs S-GW to be transmitted to P-GW also should not revised by S-GW.Otherwise, send in the administrative messag of MME or SGSN by S-GW again after S-GW is sent to for P-GW, also may comprise the parameter not needing S-GW to forward, and need S-GW to be transmitted to MME or SGSN but the parameter should do not revised by S-GW.Such as, when terminal performs initial attachment (Attach) process, need to set up default bearer.Now MME sends to S-GW and creates bearing request message, the parameter of carrying in message comprises RAT (RadioAccessType, wireless access way), the address etc. of IMSI (InternationalMobileSubscriberIdentifier, international mobile subscriber identifier), P-GW.When S-GW receives establishment bearer messages, because this message also uses in other processes, as many PDN connections and TAU (TrackingAreaUpdate, tracing section updating), S-GW are difficult to judge how to process these parameters comprised in message.For different processes, such as TAU and Attach process, MME sends to the establishment bearer messages of S-GW to comprise IMSI, only need S-GW processing locality just passable, but Attach process IMSI also needs to be sent to P-GW for TAU process IMSI.Carry other parameters of request as the address of P-GW for the establishment in Attach process, S-GW needs processing locality, but need not send to P-GW by message parameter.For the RAT parameter in TAU process, then, when the value only having S-GW to receive is different from the value that this locality is preserved, just need to send to P-GW.
At present, do not distinguish in GTPv2 these whether should Forward (forwarding) to the parameter of PGW or MME/SGSN.S-GW when processing the parameter in such administrative messag and whether forwarding and whether can revise, be all according to parameter in message the implication that implies judge whether to carry out operating.
The deficiencies in the prior art are: owing to not having UE (UserEquipment in network node, subscriber equipment) mobility management states machine, can not understand the handling process belonging to administrative messag received, therefore it can only carry out comprehensive descision according to some parameter of carrying in the GTP message of UE.Thus determine send which type of message and parameter as next network node.This will cause next network node after receiving parameter, once there is mistake, determining whether this parameter there occurs change in other network nodes by being difficult to, also therefore cannot determine whether this mistake is sent to initial message sending node, as MME/SGSN.Equally, also there is same problem on the reverse path, that is, once there is mistake, determining whether this parameter there occurs change in the network node of centre by being difficult to, also therefore cannot determine whether this mistake is sent to initial message sending node.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
Fig. 2 is the processing method implementing procedure schematic diagram of containing parameter message, as shown in the figure, when processing the message of containing parameter, can comprise the steps:
The operation that the intermediate node of parameter in message and receipt message carries out this parameter is determined when step 201, starting node create message;
Step 202, starting node identify parameter, the operation that the intermediate node that described mark comprises receipt message carries out parameter;
Step 203, starting node send the described message containing mark;
Step 204, intermediate node, after receiving the described message containing mark, operate according to described mark.
In enforcement, can comprise the operation that parameter is carried out: retransmitting paramater, condition retransmitting paramater one of them.Wherein:
The operation of retransmitting paramater refers to: the node receiving parameter reads this parameter and is transmitted to destination node.
The operation of condition retransmitting paramater refers to: the node receiving parameter judges whether this parameter meets forwarding condition, such as, whether this parameter value that the parameter value in message stores with this locality is consistent, as unanimously then forwarded, otherwise do not forward, forward when certainly also may be defined as inconsistent.
It should be noted that, what more than enumerate is the two kinds of current forwarding conventional to parameter in message operations, in fact, can also containing other various operations, the object of the present embodiment is, by the operation that the go-between entity or node of determining receipt message when building message can carry out this message parameter, reaching the faulty operation avoiding network node and network entity may produce message parameter, reducing the mistake that may exist in network and occurring.
Be described with the example of Attach, TAU process below.
One, when in Attach process, create bearing request message by MME as starting node and send to S-GW, wherein starting node M ME determines that IMSI and the RAT parameter in message must be sent to P-GW node, operated by P-GW, other network nodes in process of transmitting carry out retransmitting paramater operation to this parameter, therefore can be that node except P-GW performs the mark forwarding operation by these two optimum configurations, and indicate send to P-GW after by P-GW, IMSI, RAT parameter is operated; P-GW address parameter wherein, can not arrange forwarding operation mark, indicates that this address parameter is only issued S-GW and used.Also comprise some other parameters in this message, can perform in accordance with this rule.
Two, when in TAU process, create bearing request message by MME as starting node and send S-GW, the RAT parameter that wherein starting node M ME determines in message needs S-GW to judge whether, and RAT parameter of preserving local with it is consistent, just need this RAT to send to P-GW when only having inconsistent, now can determine that node S-GW operates RAT parameter executive condition retransmitting paramater.Be then that S-GW and S-GW executive condition forwards operation by RAT optimum configurations.
Below with starting node creative management message, intermediate node execution forwarding is operating as example and is described.
Starting node creative management message in this example, determines during starting node creative management message in administrative messag, each parameter and these parameters need to send to intermediate node or destination node, send to destination node under which kind of condition;
Concrete, what starting node carried out parameter is designated forwarding mark or condition forwarding mark, indicates intermediate node to carry out forwarding operation to parameter in described forwarding mark; Described condition forwards mark instruction intermediate node and determines that this parameter performs forwarding operation when meeting forwarding condition;
Then intermediate node is after receiving described administrative messag, and the described forwarding mark of carrying according to parameter in message and condition forward mark and determine to forward parameter and condition forwarding operation.
Wherein, intermediate node carries out the described forwarding operation forwarded in mark to parameter, is specifically as follows:
Intermediate node is sent to finish node after generating final administrative messag according to administrative messag, that can comprise unmodified in described final administrative messag, be provided with forwarding mark in administrative messag parameter, or the condition that is provided with in the first administrative messag of satisfied forwarding condition forwards the parameter of mark.
Further can comprise the processing procedure of finish node in concrete enforcement, it can comprise:
Finish node, after receiving final administrative messag, processes according to the parameter in final administrative messag.
In concrete enforcement, when identifying parameter, can identify especially by the cell carrying parameter.
Fig. 3 is the forwarding operation implementing procedure schematic diagram of the administrative messag of containing parameter, as shown in the figure, can comprise the steps: when transmitting the message of containing parameter
The parameter without the need to intermediate node amendment in administrative messag is determined when step 301, starting node creative management message.
Step 302, starting node are sent to intermediate node by carrying in administrative messag after the described parameter IE (InformationElement, cell) needing forwarding or condition to be transmitted to finish node is designated forwarding or condition forwarding.
In this step, by increasing a flag bit forwarded and a condition forwarding flag bit in IE definition, determine by arranging this flag bit, this IE should be forwarded by middle GTP processing node or condition is transmitted to final processing node, final processing node or condition should be sent to be transmitted to the IE of final processing node in those GTPv2 message, just this IE can be designated forwarding or condition forwarding when creating this message at starting node, concrete, as after arranging forwarding flag bit, when by this flag bit set, just indicate that this IE is identified as forwarding.
Step 303, intermediate node are sent to finish node after generating final administrative messag according to administrative messag, the cell that the condition that is designated that described final administrative messag comprises cell and the satisfied forwarding condition being designated forwarding described in unmodified forwards.
In this step, when the such as intermediate node such as S-GW is set in the forwarding position receiving the IE sended over as starting nodes such as MME/SGSN or P-GW, namely when this IE is identified as forwarding, intermediate node can not be modified to this IE, and needs to be sent to final GTP processing node.
Step 304, finish node, after receiving final administrative messag, process according to the parameter in final administrative messag.
In step 304, the final processing node of administrative messag can be ignored and whether receive cell containing forwarding mark.
In enforcement, administrative messag and final administrative messag can be the tunnel management messages sent between S4/S11 interface and S5/S8 interface under GTP agreement, or the binding update messages sent between S2a/S2b interface and S8b interface under PMIP (ProxyMobileIP, mobile IP agent) agreement.
It should be noted that, in existing SAE framework agreement, the function of interface is as described below respectively, in view of prior art employing is existing following interface name, therefore be described to be implemented as example, but one of ordinary skill in the art will readily recognize that when protocol variation or newly-increased interface type, be easy to make and change thus embodiment of the present invention to be applied to newly-increased interface type.
S2a: for providing the interface of user data transmission between trustednon3GPPIPaccess (believable non-3 gpp IP access) and theGateway (gateway) and relevant control and mobile management function;
S2b: the interface that user data transmission between ePDG and theGateway and relevant control and mobile management function are provided;
S4: core net SGSN and as 3GPP anchor point function S-GW between interface, for both provide relevant controlling functions and mobility functions support; This interface is based on the gn interface be defined between SGSN and GGSN; In addition, if do not set up direct-connected data tunnel, this interface provides the tunnelling function of user plane;

GTPbasedS8: be defined in different PLMN (PublicLandMobileNetwork, public land mobile network) between, VPLMN (VisitedPublicLandMobileNetwork, the public land mobile network of access) middle S-GW and HPLMN (HomePublicLandMobileNetwork, home public land mobile network) between P-GW for user provides the interface of control plane and user-plane function, this interface is based on the gp interface between SGSN and GGSN; S8a be S5 interface across PLMN version, also claim S8a interface;
Support between S8b:S-GW and P-GW, across the interface of PLMN gateway roaming condition user plane and control plane function, supports the IETFPMIP agreement of non-3 GPP access, also claims PMIPbasedS8 interface;
Interface between S10: two MME, is used for processing the information transmission between MME reorientation and MME;
Interface between S11:MME and S-GW.
Concrete, 1), when tunnel management messages is the tunnel management messages sent between S4/S11 interface and S5/S8 interface under GTP agreement, starting node of described tunnel management messages is MME or SGSN, and described finish node is P-GW; Or starting node of described establishment tunnel management messages is P-GW, and described finish node is MME or SGSN.Now, the intermediate node in enforcement can be S-GW.
When administrative messag is the tunnel management messages sent between S4/S11 interface and S5/S8 interface under GTP agreement, starting node of tunnel management messages can also be MME or SGSN, and finish node also can be S-GW; Or the starting node creating tunnel management messages can be P-GW, and finish node can be S-GW.S-GW can be judged by the parameter of carrying in message self whether concerning this message for intermediate node or be finish node, such as, can to continue to send a message to finish node or S-GW self to this message be exactly that finish node judges by carrying operation instruction parameter instruction S-GW in message.
2), when tunnel management messages is the binding update messages sent between S2a/S2b interface and S8b interface under PMIP agreement, starting node of binding update messages can be ePDG (the data access gateway of evolution) or reliable non-3 GPP access gateway, and described finish node can be P-GW; Intermediate node can be S-GW.
In concrete enforcement, initial GTP sending node can be MME or SGSN or P-GW, and final GTP receiving node can be P-GW, MME or SGSN.Initial PMIP sending node can be the data access gateway ePDG of evolution or reliable non-3 GPP access gateway, described finish node can be P-GW, or, starting node of binding update messages is P-GW, and described finish node is the data access gateway ePDG of evolution or reliable non-3 GPP access gateway; Described intermediate node is S-GW.
In enforcement, be designated and forward and can be identified by any position at cell.Concrete enforcement can be as follows:
As long as the processing node of any initial transmission GTP message thinks that the IE comprised in message should be sent to the processing node stopping GTP message, and can not by between any node on path revise, the IE in the message that just can create oneself puts and forwards flag bit to indicate that this IE is identified as forwarding.Forwarding flag bit can be ignored when the final processing node of termination GTP message receives GTP message.The forwarding flag bit of which IE needs set to be determined according to performed process and message by the processing node of initial GTP message.
In EPS, the tunnel management messages of GTPv2 sends between MME and S-GW and between S-GW and P-GW.The message expiration that some MME sends in S-GW, but also has some message to need all to send on S4/S11 and S5/S8 interface.Namely be sent to S-GW by MME/SGSN, be sent to P-GW by S-GW more afterwards; Otherwise some message is sent to MME/SGSN by S-GW again after P-GW is sent to S-GW.When S-GW receives the GTPv2 tunnel management messages of MME/SGSN or P-GW, can determine whether forwarding this message to P-GW or MME/SGSN of opposite end according to the OperationIndication carried in message (running instruction).When S-GW determines that message needs to be transmitted to peer node, also need to distinguish according to different situations which IE received in message is included in the message of forwarding.As when in ServiceRequest (service request) process, S-GW receives UpdateBearerRequest (more new bearer request) message that MME sends over, send in the UpdateBearerRequest message of P-GW after needing the RAT parameter wherein comprised to be included in; During CreateBearerRequest in Attach (attachment) process (creating carrying request) message, send in the CreateBearerRequest message of P-GW after needing most parameters to be included in.And these parameters being transmitted to P-GW not should revise by S-GW.Below for ServiceRequest process embodiment in order to illustrate at S-GW when receiving the message of containing parameter, how specifically implementation modification and forwarding, Fig. 4 is ServiceRequest implementing procedure schematic diagram, for ease of explanation, the related entities also introduced in figure has PCRF (PolicyControlandChargingRulesFunction, policy control and charging rule functions), HSS (HomeSubscriberServer, home signature user server), as shown in the figure, can comprise in enforcement:
Step 401, UE (UserEquipment, subscriber equipment) initiate ServiceRequest (service request) to eNodeB (evolution base station);
Step 402, eNodeB initiate service request to MME;
Step 403, Authentication (authentication) process;
Step 404, MME send InitialContextSetupRequest (request set up in initialization context) to eNodeB;
Step 405, eNodeB and UE set up radio bearer (RadioBearerEstablishment);
Step 406, UE send upstream data (UplinkData);
Step 407, eNodeB feed back InitialContextSetupComplete (initialization context is set up and terminated) to MME;
Step 408, MME send UpdataBearerRequest (more new bearer request) to S-GW;
The parameter such as parameter eNodeBaddress (evolution base station address), DownlinkS1TEID (s) (Tunnel Identifier of S1 interface downlink), DelayDownlinkPacketNotificationRequest (time delay of downlink packets notice request), RATType (wireless access type) is comprised in this request.
Step 409, S-GW send to P-GW and upgrade bearing request message;
If RATType changes, then S-GW sends to P-GW and upgrades bearing request message, carries parameter RATType in this message.
The modification process (PCEFInitiatedIP-CANSessionModification) of the IP interconnection network session that function gateway is initiated is implemented in step 410, strategy and control;
This process is telescopiny, and it is used for carrying out the negotiation of service strategy.Detailed process describes can see 3GPPTS23.203.
Step 411, P-GW feed back UpdataBearerResponse (more new bearer response) to S-GW;
Step 412, S-GW feed back UpdataBearerResponse to MME.
In ServiceRequest process, carry a lot of parameter in the message that the MME of step 408 sends to S-GW, but only have RATType parameter to need to be transmitted to P-GW.If MME can judge whether the RATType parameter of UE there occurs change for S-GW and P-GW, then MME forwards mark by arranging in the IE giving S-GW, thus after making S-GW receive the more new bearer request of MME, find to be provided with containing the IE of RATType parameter to forward mark, therefore S-GW does not modify to RATType parameter, and this RATType parameter is passed to P-GW in renewal bearer messages.
In enforcement, example is embodied as with the tunnel management messages sent between S4/S11 interface and S5/S8 interface under GTP agreement, but, although the protocol handler system of PMIP and GTP is different, because the PMIP agreement that uses on S2a/S2b interface and S8b interface and GTP agreement have very large general character in the transitivity of message between nodes and parameter, therefore administrative messag also can be the binding update messages sent between S2a/S2b interface and S8b interface under PMIP agreement.
