Description
Technical field
The present invention relates to charging gateway management method in the communication system, particularly in the broadband CDMA system service universal grouping wireless business supporting node to the management method of charging gateway.
Background technology
GPRS (General Packet Radio Service is called for short " GPRS ") network is a kind of cellular mobile communication networks of new generation based on global mobile system (Global System of Mobility is called for short " GSM ") network.In order to support the GPRS function, in existing GSM network, need to increase some nodes, as Gateway GPRS Support Node (Gateway GPRS SupportNode, abbreviation " GGSN "), Serving GPRS Support Node (Serving GPRS Support Node, be called for short " SGSN "), they all belong to GPRS Support Node (GPRS Support Node is called for short " GSN ").In addition, at 3G (Third Generation) Moblie (The Third Generation, be called for short " 3G ") in, Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access for example, abbreviation " WCDMA ") core net (Core Net, be called for short " CN ") in, also support the GPRS function, GSN nodes such as GGSN and SGSN are arranged equally.
GSN is a most important network node in the GPRS network, has mobile routing management function, can connect various types of data networks, and can be connected to the GPRS register, and the data that can finish between travelling carriage and the various data network transmit and format conversion.Wherein the main effect of SGSN is the current location information of record travelling carriage, and finishes the transmission and the reception of mobile packet data between travelling carriage and GGSN.GGSN mainly plays the gateway effect, and it can be connected with multiple different data network, as ISDN(Integrated Service Digital Network), Ethernet etc.
Charging Gateway Functionality (Charging Gateway Functionality is called for short " CGF ") is collected and sent to charge information by SGSN and GGSN in the GPRS network.The call detail record that CGF collects from SGSN (Call Detail Record, abbreviation " CDR ") is called SGSN call detail record (SGSN-Call Detail Record, be called for short " S-CDR "), the CDR that collects from GGSN is called GGSN call detail record (GGSN-Call Detail Record, " G-CDR ").CGF not only is responsible for collecting metering data, but also is responsible for metering data is sent to account system (BillingSystem is called for short " BS ").
Present SGSN and charging gateway (Charging Gateway, abbreviation " CG ") uses GPRS Tunnel Protocol (the GPRS Tunneling Protocol ' that improves between, be called for short " GTP ' ") carry out transfer of data, and send the GPRS CDRs that is produced among the SGSN to CG.The agreement that GTP ' is this to be used to collect GPRS CDRs is to derive from GPRS Tunnel Protocol (GPRS Tunneling Protocol is called for short " GTP "), and the GTP agreement is used for the transmission of GPRS backbone network packet datagrams in the tunnel just.
GTP ' agreement is the improvement to the GTP agreement, and has increased several type of messages.GTP ' agreement operates on GA interface (general-purpose interface between SGSN/GGSN and charging gateway), mainly realizes following function:
1, between GPRS node and charging gateway, transmits CDRs;
2, CDRs is redirected on other charging gateway;
3, by between ECHO message detection GPRS node and the charging gateway whether communication failure being arranged;
4, after breaking down, Correspondent Node can regularly detect the service of whether having recovered;
5, prevent that CDRs from repeating.
Communications protocol layers between SGSN and the CG as shown in Figure 1.Wherein CDRs comprises following a few class: S-CDR, M-CDR, G-CDR, S-SMO-CDR, S-SMT-CDR.S-SMO-CDR, i.e. the Mobile Originated short message-call detail record of SGSN transmission (SGSN delivered Shortmessage Mobile Originated-Call Detail Record is called for short " S-SMO-CDR "); S-SMT-CDR, i.e. (SGSNdelivered Short message Mobile Terminated-Call Detail Record is called for short " S-SMT-CDR " the mobile terminated short message-call detail record of SGSN transmission.
The type of message of GTP ' agreement has 9 kinds, i.e. Echo Request (replying request), EchoResponse (replying response), Version Not Support (version is not supported), Node Alive Request (node activates request), Node Alive Response (node activates response), Redirection Request (redirect request), Redirection Response (redirect response), Data Record TransferRequest (data record transmission request) and Data Record Transfer Response (data record transmission response).Divide 4 flow processs to introduce the working mechanism of GTP ' agreement with reference to the accompanying drawings.
Fig. 2 shows the ECHO flow process.The ECHO flow process is two-way.Whether be used for detecting normal to method, apparatus or circuit, either party, the recipient must return Echo Response after receiving this message if can send Echo Request by equipment, otherwise will the side of being sent out think equipment fault or line interruption.Have two message in the Echo flow process: Echo Request message and Echo Response message.
Fig. 3 shows Node Alive flow process.Node Alive flow process is two-way.Be used to notify the other side's node, local terminal equipment or other equipment start, can operate as normal.Have two message in the Node Alive flow process: Node Alive Request message and Node Alive Response message.
Fig. 4 shows the Redirection flow process.The Redirection flow process mainly contains two purposes: owing to safeguard or when breaking down, CG advises SGSN, and ticket is mail to other CG (the CG address of containing suggestion in the message).CG notifies SGSN, and the memory device of CG or CG and BS communicating interrupt need SGSN that ticket is mail to other CG (the CG address of containing suggestion in the message).The Redirection flow process has two message: Redirection Request message and Redirection Response message.
Fig. 5 shows Data Record Transfer flow process.Data Record Transfer flow process is unidirectional.Be used for SGSN and send CDRs to CG.SGSN sends to CG by Data Record Transfer Request with call bill data, CG must return Data Record Transfer Response after receiving Data Record Transfer Request message, otherwise the side of being sent out is thought that call bill data does not send success.Have two message in the Data Record Transfer flow process: Data Record Transfer Request message and Data Record Transfer Response message.
As mentioned above, at present described in detail in GTP ' agreement all is communication interaction technology between relevant SGSN and the CG, can't manage CG and state thereof at the SGSN end, particularly disposed under the situation of a plurality of CG, how a plurality of communication objects have been managed at present also without any relevant standard at SGSN.
In addition, sent ticket unconfirmed, but after breaking down, this brings in from SGSN,, tend to also make that the record of this CG is kept at the SGSN end all the time even after carrying out re-orientation processes when certain CG still has.Operation may make SGSN preserve more useless CG recorded information for a long time.
In actual applications, there is following problem in such scheme: at first, can't manage a plurality of CG and state thereof at the SGSN end; In addition, can make relative recording remain at SGSN after the CG fault holds and is not eliminated.
Cause a main cause of this situation to be, Current Standard can not solve SGSN to the problem that a plurality of CG and state thereof manage, and does not handle the method for removing record after the CG fault at the SGSN end simultaneously.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
The present invention relates to a kind of moving communicating field particularly the SGSN in GPRS field to the management method of a plurality of CG.
Use GTP ' agreement to communicate between SGSN and the CG as previously mentioned, and the communication conformance with standard in order to make between SGSN and a plurality of CG, can make the transmission of ticket not lose does not repeat, being convenient to SGSN manages a plurality of CG, and hold the record that keeps at SGSN after can handling the CG fault, the present invention provides the detailed solution of a cover, comprises after the method, CG fault of the definition of definition, CG state of CG initial method, message structure that CG is relevant and state exchange thereof the processing method for the record that is retained in the SGSN end.To describe the implementation method of a preferred embodiment of the present invention below in detail.
At first, SGSN sends and accepts various types of messages in order to manage each CG communication object, makes corresponding processing at variety of event, and the present invention adopts communication and the management thereof of state transitions mechanism realization to each CG.
According to the actual conditions that occur in the communication process, in a preferred embodiment of the present invention, four kinds of states of definition CG are: init state, normal condition, malfunction, idle condition.
Wherein init state represents that SGSN carries out initialization to CG, and initialized method will provide below; Normal condition represent between SGSN and the CG communicate by letter normal; Malfunction represents that communicating by letter between SGSN and the CG break down, perhaps because other reasons makes SGSN not continue situation about communicating by letter with CG; Idle condition is represented to communicate by letter with CG and is finished or no initializtion still.
More than four kinds of states comprised SGSN begin to communicate, communicate by letter normal with CG or interruption, communication redirection, this whole process of sign off in all states, this has guaranteed that SGSN can realize GTP ' protocol communication to the condition managing mechanism of CG.
Those of ordinary skill in the art are appreciated that above several state can split or merge, and can realize goal of the invention as long as corresponding step and processing method are made corresponding change, and not influence the spirit and scope of the invention.
For the ease of realizing that SGSN manages and handle communication event to CG, in SGSN, each CG is provided with a CG message structure, be used for concentrating the information of preserving this CG, SGSN is when managing a plurality of CG, from corresponding C G message structure acquired information, make processing, and in processing procedure, can revise the member variable value of message structure incident.
In a preferred embodiment of the present invention, the CG message structure realizes with structural array, is stored in the corresponding medium of SGSN, comprises following member variable: the CG Status Flag is used to indicate CG present located state; The CG self-information such as the grade of CG, the attribute of CG, the agreement of carrying etc., is used to characterize characteristic and the parameter of this CG; The counter that SGSN and CG signal post need to the IP address of parameter: CG, the transmitting and receiving terminal slogan of SGSN, the index value that is redirected CG, signal post, the parameter of ticket transmit queue etc. are used to provide signal post needs between SGSN and the CG parameter and counter.
Wherein, the attribute of CG can only be 2.5G or 3G, and a kind of CG of attribute can only handle the ticket of respective type, therefore the ticket of 2.5G is pressed 2.5G format of billing coding, can only mail to the CG that can handle 2.5G form ticket, the ticket of 3G is pressed 3G form coding, can only mail to the CG that can handle 3G form ticket.
Those of ordinary skill in the art are appreciated that the member variable that above-mentioned CG message structure comprises can increase and decrease or change as required, and do not influence the spirit and scope of the invention.
Before communicating by letter between SGSN and CG set up as yet, system carried out initialization operation.In a preferred embodiment of the present invention, as shown in Figure 6, initialized method comprises following steps:
At first enter step 61, system is a CG message structure application internal memory, and the size of internal memory supports the number of CG to decide according to system.The CG message structure exists with the form of structural array, the corresponding corresponding C G of each CG message structure.When SGSN increases a CG communication object and distribute corresponding C G message structure, the information that record is relevant.
Then enter step 62, system reads the CG information list in the configuration database (Configuration Database is called for short " CDB "), and the member variable value in each CG message structure is set in order.The database that the CDB here provides when being system design is used for the configuration parameter of saved system, comprises the required data of CG initialization.As if reading illegal numerical value or not existing, then Use Defaults.After setting up the CG message structure, just there is a map in CG in SGSN, can manage it.
Then enter step 63, system is made as init state with the CG Status Flag of preparing to distribute in the corresponding CG message structure of CG.Show that corresponding CG prepares to communicate with SGSN.
After system initialization finishes, SGSN and a plurality of CG will carry out dynamic communication process based on GTP ' agreement.In communication process, the standard SGSN according to GTP ' agreement must manage a plurality of CG as mentioned above, and incident is made respective handling.The present invention provides a state exchange mechanism, realizes condition managing and the event handling of SGSN to a plurality of CG.
Below with reference to Fig. 7, be described in state exchange mechanism and processing method under four kinds of states in the preferred embodiment of the present invention respectively according to different conditions.
Under init state, SGSN sends Node Alive Request message to CG, start node simultaneously and activate the response timer, if the response of before timer expiry, not receiving Node Alive Response message, then resend Node Alive Request message, surpass the response that preset upper limit is not also received Node Alive Response message until overtime number of times, initialization failure 75 then is described, CG Status Flag in the CG message structure of CG correspondence is set to fault, enters malfunction; Otherwise the response of receiving Node Alive Response message illustrates initialization success 72, and the CG Status Flag in the CG message structure of CG correspondence is set to normally enter normal condition.
Here SGSN adopt to send Node Alive Request message and shows to CG that local terminal has been ready for communication and has been required opposite end CG to beam back Node Alive Response message method in response and judge whether communication link is normal, if communicate by letter successfully specifically, illustrate between SGSN and the CG communicate by letter normal, can enter normal condition communicates, otherwise, illustrating communicates by letter can't carry out--and link failure or CG are in maintenance state, need enter malfunction, wait for the message of CG.
Under normal condition, SGSN and CG communicate, and comprise following operation: SGSN to the CG transmit telephone bill, start the ticket transmission timer simultaneously; SGSN sends Echo Request message to CG, and starts answer response timer.Wherein the ticket transmission timer is used to confirm to receive whether within the predetermined time the response of ticket arrival, if then do not resend this ticket; Equally, reply the response timer and be used to confirm the response of whether in official hour, receiving Echo Response message, if then do not resend Echo Request message.
Under SGSN and CG proper communication situation, if following incident occurs:
SGSN receives the Redirection Request message that CG sends, and illustrates that this CG can't communicate by letter, and request is redirected to other CG;
SGSN sends the ticket maximum number of retransmissions that same frame call bill data number of times reaches the backstage configuration to CG;
SGSN does not receive that continuously the number of times of the response of Echo Response message reaches preset upper limit;
SGSN receives the Version Not Support message that CG sends, and the version number of description protocol is not supported;
Then represent the communicating interrupt 73 of SGSN and CG, SGSN need do following processing:
CG Status Flag in the CG message structure of CG correspondence is set to fault, enters malfunction;
Send the CG fault warning to the backstage, because CG is redirected and version when not supporting, send that CG is redirected and version is not supported event alarm respectively to the backstage when former.
When the sign off between SGSN and the CG, SGSN carries out CG deletion 76, then the CG Status Flag in the CG message structure of CG correspondence is provided with the free time, enters idle condition.
Here SGSN judges by timer whether the response of CG arrives at the appointed time, if overtime then reappears sending, to avoid the situation of last information drop-out, if surpass predetermined repeating transmission number of times, it is undesired then to be judged as link failure or CG communication, enters malfunction.In addition, if CG request is redirected, then system is made as malfunction with this CG, stop to communicate with, and the operation that is redirected according to the reorientation method of stipulating in the standard.
Under malfunction, SGSN stops the transmission message operation to CG, if receive the following message that this CG sends: Echo Request message, Echo Response message, Node Alive Request message, Node Alive Response message, Version Not Support message, Data RecordTransfer Response message, and this message format is entirely true, GTP ' protocol version is not higher than the version that SGSN supports
Illustrate that then the CG communication recovers 74, SGSN does following processing:
CG Status Flag in the CG message structure of CG correspondence is set to normally enter normal condition, and the version number of GTP ' agreement is set;
Send CG to the backstage and recover normal alarm.
When receiving this CG, SGSN do not send any message, and this fault of decision deletion CG, carry out CG deletion 77, then the CG Status Flag in the CG message structure of CG correspondence is provided with the free time, enter idle condition.
Here SGSN message that the CG under the malfunction is sent judges whether correctly, if, illustrate that this CG recovers normal, enter normal condition, attempt communicating with this CG.In addition, if GTP ' version of CG is higher than the version that SGSN supports, and can not obtain when consulting, then the state of CG can not move to normally.
Under idle condition, when this CG message structure of system assignment is carried out initialization to new CG and to it, then the CG Status Flag in the CG message structure of CG correspondence is provided with initialization, enter init state.
Those of ordinary skill in the art are appreciated that, some predetermined parameters in the above handling process, such as timer duration, the number of repetition upper limit etc., and some steps, such as the redirection steps after the change of CG state, can in the light of actual conditions determine or change, and do not influence the spirit and scope of the invention.
Since SGSN with exist CG to be redirected problem during CG communicates by letter, detailed description CG reorientation method below,
At first, the transmit frame message structure of corresponding C G is set in SGSN, for each CG, the relevant information of each frame data that preservation sends to CG, for each CG relevant information of the m frame data that send recently of record accordingly all, and m is the CG frame number upper limit of response frame not of backstage configuration.This structure has guaranteed, when CG breaks down, when perhaps being redirected, all not the relevant information of response frame can both in CG transmit frame message structure, regain, can not send to redirected CG with sending successful Frame after feasible being redirected, finish redirect operation.
Fig. 8 shows the message structure of the CG in the preferred embodiment of the present invention and the transmit frame message structure corresponding relation of CG.
Then, when after CG breaks down or receives the redirect request that CG sends, entering malfunction, SGSN checks the transmit frame message structure of this CG, with the Frame that is not responded, send to and be redirected CG, the information that is redirected CG is here obtained from the CG message structure of former CG or is obtained from the redirect request that former CG sends.
Receive when redirected later transmit frame is redirected CG, show that then this transmit frame is sent out, so,, inform that then all these frames of redirected CG of this transmit frame are received if this transmit frame repeatedly is redirected with the relevant record deletion that keeps among the SGSN.
Fig. 9 shows the treatment mechanism to SGSN end record after the CG fault.
Here need to prove, different Frames can be redirected to different CG, and the CG after being redirected is if fault and make this frame can not send success, then this frame will be redirected once more, up to sending successfully, after sending successfully, because the record that this frame is relevant all is stored among SGSN and all CG that once sent, so SGSN sends release command to the CG that each once sent this frame, make these CG delete the record of relevant this frame, avoid recovering this Frame of normal reprocessing and causing ticket to repeat as certain CG.And in the environment of reality, the emergency case that may run into has many, as the communication link between CG and the SGSN break down, CG restarts etc., if after moving considerable time, the original CG that disposes of SGSN has many in use, but still keeping a large amount of record ignoreds at the SGSN end,, avoiding unnecessary record expense here so SGSN exists local relevant this frame and the record of this fault CG with deletion.
Though by reference some preferred embodiment of the present invention, the present invention is illustrated and describes, but those of ordinary skill in the art should be understood that, can do various changes to it in the form and details, and the spirit and scope of the present invention that do not depart from appended claims and limited.
