Description
Technical field
The present invention relates to LTE technical fields, particularly relate to a kind of time-based session routing iinformation consistency desired result side
Method and device.
Background technique
In LTE (Long Term Evolution, long term evolution) system introduce Diameter signaling interface, need by
DRA (Diameter Routing Agent, route agent's node) switching Diameter signaling.
After introducing LTE, SAE (System Architecture Evolution, network architecture system evolution) network will be
LTE user provides mobile management and service bearer channel, and the network architecture is as shown in Figure 1, include MME (Mobility
Management Entity, mobility management entity), S4-SGSN (Serving GPRS Support Node, service GPRS
Supporting node), EIR (Equipment Identity Register, equipment identity register), SAE GW (Gateway, net
Close) and HSS (Home Subscriber Server, home subscriber server), user number is wherein pressed in ownership place HSS database
The user data of section storage LTE user.When LTE user roams under the MME network element of visited place, MME can be sent out to user attaching HSS
Play location updating and authorizing procedure.These processes are all to be realized in SAE network using Diameter signaling protocol, signaling association
View stack is Diameter/SCTP (STREAM CONTROL TRANSMISSION PROTOCOL, Flow Control Transmission Protocol)/IP
(Internet Protocol, network protocol).
In addition to this, there are also the Gx of PCC (Policy Control and Charging, policy control and charging) framework,
Rx, S9 interface also will use Diameter, as shown in Figure 2.
In order to which maintenance management is convenient, it will use DRA network element when realizing Diameter message routing, transferred by DRA
Between MME and HSS, PGW (Packet Gateway, packet data gateway) and PCRF (Policy and Charging Rules
Function, Policy and Charging Rules Function) between all signalings, to avoid full connection bring whole network data configuration
Maintenance issues, as shown in Figure 3.Gx interface signaling uses between S6a interface and PGW and PCRF between DRA switching MME and HSS
Static routing strategy (such as IMSI (International Mobile Subscriber Identification Number, state
Border mobile identification number), MSISDN (Mobile Subscriber International ISDN/PSTN number, move
Dynamic Subscriber Number), host name) addressing.As shown in figure 4, DRA is disposed in pairs, is mutually backups, load to guarantee security reliability
It shares.
After introducing VoLTE (voice service based on IP multimedia subsystem), to guarantee speech service quality, meeting is introduced
Policy Control mechanism is talked about, needs to establish dedicated bearer according to session control policy application when user initiates calling.In dedicated bearer
In establishment process, the Rx interface being related between AF (Application Function, application function) and PCRF, the interface signaling
Dynamic binding information of the addressing strategies based on Gx interface, reference flowchart are as follows:
(1) UE establishes default bearing, and PGW is online by Gx interface notification PCRF user, while obtaining user tactics information；
(2) UE initiates call request by default bearing；
(3) AF is interacted by Rx interface with PCRF, is issued dedicated bearer and is established request；
(4) PCRF issues dedicated bearer qos policy to PGW by Gx interface；
(5) AF notifies other network elements to complete subsequent call flow.
It can be seen that user from above-mentioned process and establish default bearing and dedicated bearer and need to be controlled by the same PCRF, Gx
Interface and Rx interface signaling need to be addressed to the same PCRF.
Rx interface can only be addressed that this just proposes high requirement to DRA by IP address at present, need dynamic memory
The binding session information (corresponding relationship of IP address and PCRF) of Gx interface.Binding session information database in DRA is dynamic
State stores the binding session information of online user, and net, IP address variation and shutdown bring Gx interface signaling are stepped in user's booting
It will create, modify and delete the binding session information in database.The Rx interface signaling of one user addresses dialogue-based binding
Corresponding binding session information in information database.
Since signaling network disposes DRA in pairs, Gx interface signaling, a user are sent to P-GW load sharing to a pair of of DRA
Binding session information may be created by DRA1, by DRA2 modify or delete.A pair of of DRA is likely to the meeting of one user of modification
Talk about binding information.Equally, Rx interface signaling, the Rx interface signaling of possible a user are sent to AF load sharing to a pair of of DRA
It is sent to DRA1, but binding session data are on DRA2, it is therefore necessary to guarantee that any one DRA in a pair of DRA must be stored
The binding session information of all users in covered signaling tandem area, and it is ensured of newest data.
The binding session information of DRA is stored by dynamic data base at present, and the synchronization of binding session information passes through DRA's
Sync cap is realized.It is complete for the binding session information that is stored in the dynamic data base on two DRA ensuring to match each other
Unanimously, except support real-time synchronization also needs to carry out consistency for the binding session information stored in database in sync cap
Verification.
Data in the binding session database of one DRA may trigger modification due to the Gx interface signaling that oneself is received,
It may also be modified by sync cap by DRA2.During consistency desired result, three kinds of situations can cause in database simultaneously
Data modification: 1) consistency desired result data are received and cause data modification；2) signaling interface triggering session binding information is modified；3) right
End DRA initiation real-time incremental, which synchronizes, causes data modification.
Between existing a pair of DRA when carrying out consistency desired result to binding session information, the verification frequency is lower (such as in one day
Verification 1-2 times).Both ends use symmetrical verification mode and full dose verification scheme, i.e. DRA1 initiates consistency desired result to DRA2, accuse
The full dose data for knowing DRA2 oneself, are verified by DRA2.Conversely, DRA2 also initiates consistency desired result to DRA1, DRA1 is informed
The full dose data of oneself, are verified by DRA1.
There is Railway Project in practical applications in existing consistency desired result mechanism:
1, the online user of DRA service may be up to ten thousand, and when carrying out consistency desired result, DRA need to be transmitted largely in sync cap
Synchrodata will affect the transmission and write-in of the performance of database and the data of real-time synchronization.
2, to avoid the influence to performance and time delay, often by consistency desired result process be placed on the signaling amount lower period into
Row (such as night).Because night, many users had been switched off, and telephone traffic is very low, but carries out the meaning of consistency desired result at this time
It is smaller, it is difficult to guarantee a pair of DRA in early busy and the consistency of late busy institute storing data.
3, it since consistency desired result transmission data are excessive, may be also not finished in consistency desired result, user's correlation Gx interface
Or increment synchronization has had updated binding session information, leads to the reduction of consistency desired result efficiency.
