Abstract
A charging-control method includes reporting the first state information by node at state corresponding to charging initial point and triggering up charging when the first state information is received by gateway or deciding whether to trigger up charging or not by gateway according to current state identification carried in state information.
Description
Technical field
The present invention relates to the multi-media communication field, disclose a kind of billing control method especially.
Background technology
H.323 the protocol suite of International Telecommunication Association (ITU-T) suggestion is through years of development, become VOIP (VoiceOver IP, IP-based voice) and the main flow industrial standard of video conference application, wherein comprised realizing one based on the required entity of the multimedia communications system of packet network and the suggestion of entity interaction agreement.In the multimedia communications system, generally all comprise GK (Gatekeeper, the gatekeeper), Gateway (gateway), MCU (Multipoint Control Unit, multipoint control unit), four kinds of entities of Terminal (terminal), wherein in the network system of operation level, GK is the manager of whole H.323 system, is responsible for finishing functions such as district management, access control, address resolution.
H.323 protocol suite comprises RAS (Registration Admission and Status) registration call access signaling, Q.931 call signaling, H.245 channel control signaling and RTP (Real Time Protocol, RTP)/RTCP (Real Time Control Protocol, RTCP Real-time Transport Control Protocol) agreement.The RAS signaling is used for mutual between node and the GK, node by the RAS signaling finish registration on GK, call out insert, state upgrades; Q.931 signaling is used for calling procedure between the node, finishes the foundation and the dismounting of calling procedure; H.245 signaling is used for the control of media channel between the node, finishes the opening and closing of principal and subordinate's decision, capabilities exchange, logic channel; RTP/RTCP is used for the carrying and the control of video/audio code stream.Commonly used in the concrete reciprocal process to following signaling:
ARQ:Admission Request inserts request;
ACF:Admission Confirm, admission confirm;
ARJ:Admission Reject, admission reject;
RRQ:Registration Request, register requirement;
RCF:Registration Confirm, accreditation verification;
RRJ:Registration Reject, the refusal registration;
LRQ:Location Request, the request gatekeeper provides address translation;
LCF:Location Confirm, address translation is confirmed;
LRJ:Location Reject, the refusal translating address;
Setup: the request of connecting;
Call proceeding: connect in the progress;
Alerting: ring signaling;
Connect: connect signaling;
IRQ:Information Request, the information inquiry signaling;
IRR:Information Request Response, information request is replied signaling.
GK is as the manager in whole H.323 territory, must support the RAS signaling, select to support Q.931, signaling H.245, node must support RAS, Q.931, H.245, the RTP/RTCP signaling, the process of multimedia communication be exactly H.323 entity use H.323 agreement to carry out mutual process.Communication process generally comprises route pattern and node is directly exhaled two kinds of patterns of pattern:
GK is operated in route pattern following time, and the Q.931 call signaling between the node, H.245 call signaling (if GK supports H.245 signalling route) all can pass through GK, then the accurate controlling call process of GK.But because Q.931, H.245 signaling connects based on TCP, though can realize accurate charging under this pattern, increased the load of GK and the time delay of call proceeding, influenced performance and the capacity of GK, for big capacity carrier-class operation network, formed a very big bottleneck undoubtedly.
When node was directly exhaled pattern, GK was operated under the non-route pattern, had only the mutual of RAS signaling between node and the GK, and GK finishes address resolution and calls out the function that inserts, to carry out Q.931 successively between the node, H.245, RTP/RTCP mutual.GK load is less under the non-route pattern, but GK does not know interactive signaling situation between end points, the function of controlling call a little less than, can't realize accurate charging.
Accurately chargeing is the prerequisite guarantee of network operation, though node directly alternately Q.931 the call signaling pattern praised highly by enterprise and telecom operators with characteristics such as its efficient, big capacity.But, because GK is route signaling Q.931 or H.245 not, Setup, the Connect etc. that set up to call out Q.931 follow-up and H.245 signaling fully without GK, cause GK out of hand to the calling behavior, can not utilize the signalings such as Setup, Connect in the call signaling Q.931 to determine the trigger point of beginning of chargeing, thereby can't guarantee charging accuracy and reliability.
Summary of the invention
The present invention discloses a kind of billing control method, solving in the prior art, and when node directly alternately Q.931 during call signaling, gatekeeper's can't guarantee to charge problem of accuracy.
A kind of billing control method, be applied in the gatekeeper when being operated in non-route mode of operation, calling between the node is chargeed, determine the charging starting point and trigger charging, when calling is hung up, finish to charge by the state information that the gatekeeper reports in calling procedure according to node.
According to described method, gatekeeper's instructs node in returning to the admission confirm signaling of node reports described state information.
According to described method, node reports first state information at the state of described charging starting point correspondence; Trigger when the gatekeeper receives this first state information and charge.
According to described method, realize that described node reports the method for first state information to comprise at the state of described charging starting point correspondence: the state that is arranged on described charging starting point correspondence in the node side reports the handling process of first state information in advance, receives that by node indication starts this handling process when reporting the affirmation message of described state information; Perhaps, the described state corresponding with the charging starting point determined according to user's configuration information by the gatekeeper, and be carried in the admission confirm signaling and send to node, reports first state information by node at this corresponding state.
In the described method, the correlation behavior information that node carries in the admission confirm signaling according to the gatekeeper reports a state information when each described correlation behavior, and carries the sign that shows current state in described state information; The gatekeeper whenever receives a state information, according to the current state of described sign recognition node, and puts to trigger when corresponding in the pre-configured charging triggering of described current state and user and charges.
In the described method, node is after reporting first state information, and the duration that every interval is set carries out the periodicity increase again and reports once described state information.Described duration determined by the gatekeeper, and is carried in the admission confirm signaling and sends to node.
And, when the gatekeeper does not receive the described state information that node reports in each described duration, sending query messages to node and carry out status poll, first duration begins to calculate after node returns the admission confirm signaling from the gatekeeper.
In the described method, the number of times that gatekeeper's side preestablishes inquiry carries out cyclic query, and hangs up calling when also not receiving described state information after having inquired about set point number.
Described state information is replied signaling by information request and is sent, and described query messages sends by the information inquiry instruction.
Beneficial effect of the present invention is as follows:
The method of the invention has realized that the gatekeeper is operated in the function of accurately chargeing under the non-route pattern, big capacity that non-route gatekeeper has itself, underload, advantage such as efficient have promptly been kept, suitable control be can realize again, charging accuracy and reliability guaranteed calling out.
Description of drawings
Fig. 1 is that the gatekeeper is operated under the non-route pattern in agreement H.323, uses the flow chart that the method for the invention is accurately chargeed.
Embodiment
The present invention provides a kind of charging method for protocol multi-media communication system H.323, realization flow as shown in Figure 1, Fig. 1 has described and has striden under GK (not route) pattern, two H.323 node carry out the basic procedure of communication, how to utilize the method for the invention on GK, to realize accurately chargeing thereby further specify.This figure realizes striding the calling networking diagram of GK by GK1 and GK2 with node 1 and node 2, GK1 and GK2 are adjacent, H.323 the caller node 1 of agreement is registered in GK1, called node 2 is registered on the GK2, and the normal H.323 call flow with the called node 2 of caller node 1 calling describes the details that the present invention realizes in detail below.
S1, caller node 1 send the ARQ request to the gatekeeper GK1 that is belonged to, and request address is resolved;
S2, gatekeeper GK1 send the LRQ request in the address of local parsing less than called node 2 to corresponding neighbours gatekeeper;
After the gatekeeper GK2 that S3, called node belonged to receives LRQ request, local parsing to the address of called node 2 also to the gatekeeper GK1 return the LCF signaling, wherein mainly comprise the call signaling address of the called node 2 after the parsing;
After S4, gatekeeper GK1 receive the LCF signaling that gatekeeper GK2 returns, send the ACF signaling, wherein mainly comprise the call signaling address of called node 2 to caller node 1;
After S5～S10, caller node 1 are received the ACF signaling of gatekeeper GK1 transmission, call signaling address according to called node 2, and signaling such as the Setup in the mutual call signaling, Call proceeding, Alerting, Connect and connecting between the called node 2, after comprising also that wherein called node 2 is received caller Setup, GK2 sends the ARQ request and inserts calling to the gatekeeper, and GK2 returns the process of ACF call accepted to node 2.
Because Setup, Call proceeding, Alerting, call signalings such as Connect are mutual between between node, therefore, be that caller gatekeeper GK1 or called gatekeeper GK2 can't determine between node the correct time of each state in the calling procedure, so all can not obtain suitable charging triggering point, at this moment, must could realize accurate billing for the gatekeeper state information report of oneself by node, in agreement H.323, can utilize the IRR signaling uploaded state information in the existing RAS signaling, according to the existing H.323 regulation of agreement and the working method of different nodes, can realize by following three kinds of methods:
Method one:
The gatekeeper is in returning to the ACF signaling of node, comprise the field that an instructs node initiatively reports the time interval of IRR signaling: IRRFrequency, it is to return to node behind the duration of unit with the second that the gatekeeper is changed to the IRRFrequency field concrete, according to agreement regulation, long periodicity initiatively reports the IRR signaling when requiring then that H.323 node is according to this;
Node periodically reports the IRR signaling in calling procedure, the gatekeeper triggers during according to first IRR signaling of receiving and charges.If node is not supported UUIE, node reports the method for first IRR signaling can only be by being provided with in the handling process of node side in calling procedure, when requiring node in receiving the ACF signaling that the gatekeeper returns, to have above-mentioned cycle indication, state a setting begins to report the IRR signaling, because it is more reasonable to begin to charge after Connect, therefore generally all be to be provided with to decide node and after Connect, report first IRR automatically, the idiographic flow method to set up is known by present technique field personnel, repeats no more here.
Method two:
If node is supported UUIE, insert the ARQ signaling of calling with the set of WillSupplyUUIES field in request, express support for UUIE, then the gatekeeper is when node returns ACF, the UUIESRequested field is put a state set, and the charging start trigger point that on the gatekeeper, disposes in advance according to the user, for example Setup or Connect, with the corresponding states set in this state set, H.323 expression requires node when reaching this state, beginning reports IRR to the gatekeeper, and GK still can accurately charge according to first IRR that node reports like this.
Under this mode, the charging start trigger point that can dispose on the gatekeeper according to the user flexibly starts charging.
In above-mentioned two kinds of methods, node reports in gatekeeper's the IRR signaling can not carry the identification information that shows current state, only needing to start charging according to first IRR signaling of receiving in gatekeeper's side gets final product, need to select to utilize method three under the situation of different operating state in the detail knowledge node calling procedure more the gatekeeper.
Method three:
This method still is applied to node and supports UUIE, at this moment the IRR signaling that reports of node can be carried the information that shows the node current state, after node is received the ACF that the gatekeeper returns, when node satisfies the state of ACF signaling indication in calling procedure, report the IRR signaling that has H.323pdu (under the pdu in perCallInfo) to the gatekeeper, H.323pdu concrete information can show node present located state (Setup in, Connect or other state), when therefore the gatekeeper receives each IRR, can be according to the information decision node present located state H.323pdu, and utilize user configured charging start trigger point, whether decision triggers charging.
This implementation method H.323pdu of being with in IRR is compared with the method that begins uploaded state in the ACF indication, need the gatekeeper when receiving IRR each time, to judge that all still, the gatekeeper can omnidistance each state of grasping node in the calling procedure to the current state of node.
In addition, reliability for the enhanced system charging, the gatekeeper is in the cycle of each IRRFrequency regulation, if when not receiving the IRR signaling that node reports, send the IRQ signaling to node and carry out status poll, first cycle is returned the ACF signaling from the gatekeeper to node and begins to calculate, GK sends the IRQ inquiry to node, when node is received the IRQ signaling, replys IRR to GK, if inquire about in first cycle, in method one and method two, the gatekeeper still can utilize first IRR signaling of receiving to trigger and charge, if GK never receives the IRR signaling of replying, then think node off-line, hang up calling.
According to above-mentioned design, charging method of the present invention also comprises the following steps:
If S11 regulation calling both sides all is to report IRR after connecting, promptly finishing the Connect step, then caller node 1 and called node 2 are after setting up the Connect signaling, report IRR to gatekeeper GK1 that is registered and GK2 respectively, gatekeeper GK1 and GK2 utilize first IRR that at first receives as the charging triggering point respectively, trigger to begin to charge;
Perhaps, the corresponding state that caller node 1 and called node 2 are indicated in the UUIESRequested state set begins to report IRR, and gatekeeper GK1 and GK2 still utilize first IRR that at first receives as the charging triggering point respectively, triggers to begin to charge;
Perhaps, caller node 1 and called node 2 trigger charging according to configuration information at corresponding charging state by the gatekeeper in the H.323pdu decision node current state of the middle band that reports IRR.
S12, gatekeeper GK1 and GK2 are hung up calling when receiving the DRQ that node reports (Disengage Request withdraws from request) request, trigger and finish the charging that call out on this road.Perhaps send DRQ to node and hang up when calling out, trigger and finish the charging that call out on this road by the gatekeeper.
The foregoing description only is to be that example describes with IRR signaling and IRQ signaling, does not get rid of the possibility of utilizing other similar signalings or proprietary signaling specific implementation, and other methods that are equal to all should be included within protection scope of the present invention.
The beneficial effect that technical solution of the present invention is brought is as follows:
The method of the invention has realized that the gatekeeper is operated under the non-route pattern, carries out the function of accurate charging, Namely kept the big capacity that gatekeeper itself has, underload, the advantage such as efficient, can realize again suitable to what call out Work as control, guaranteed accuracy and the reliability of charging.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from this Bright spirit and scope. Like this, if belonging to claim of the present invention, these modifications of the present invention and modification reach The range of its equivalent technologies, then the present invention also be intended to comprise these change and modification interior.
