Fig. 5 is the schematic diagram that influences the number analysis process of backward office according to the forward office of the embodiment of the invention, as shown in Figure 5, when the called subscriber B in the calling subscriber A call switch 2 in the switch 1, calling subscriber A off-hook is listened dialing tone afterwards and is dialed the number of called subscriber B; 1 couple of called number B of switch carries out number analysis, and discovery need be called out on another switch 2, so carry out the operation of routing.When carrying out routing, switch 1 wishes to influence the analysis of 2 pairs of called numbers of switch, comes called number is analyzed with the number analysis device of appointment, therefore writes down " contextual tagging ".This contextual tagging is the content that switch 1 and switch 2 are appointed, is used to specify special number analysis device.Switch 1 carries this " contextual tagging " in Invite message when this calling is sent to switch 2.After switch 2 is received Invite message, identify this " contextual tagging ", carry out the process of calling out preanalysis, search record sheet and obtain " contextual tagging " corresponding number analysis device, and come called number is carried out number analysis with this number analysis device, and land to called subscriber B.Like this, just realized the influence of number analysis process on 1 pair of switch 2 of switch.
Through consultation " contextual tagging " called out the preanalysis between two switches, and other information in the message that switch 2 can also be come in to switch 1 are carried out the condition coupling, thereby obtain the number analysis device of appointment.
Fig. 6 is the flow chart of handling according to the calling preanalysis of the embodiment of the invention, as shown in Figure 6, comprises that following step S602 is to step S612:
Step S602, goes into the territory and brings caller and called relevant information (that is above-mentioned steps S402) at Incoming.
The calling of going into soft switch by media conversion (TG) and signaling conversion (SG) with PSTN end office (EO) is an example: behind calling subscriber's off-hook, this off-hook event of PSTN switch perception is to caller Sending dialled number sound.The calling subscriber begins dialing, and switch A detects dialing rule by turn; After the PSTN switch is collected whole called numbers, carry out the process of number analysis and routing, determine next jumping switch according to the routing table of configuration: the TG of soft switch and SG node; The PSTN switch is selected a voice bidirectional relaying Bearer Channel DS0, generates signaling message IAM (Original Signaling Point A, destination signaling point B) and sends to soft switch SG node.At the SG of soft switch node, the IAM message that PSTN end office (EO) sends is packaged into M3UA message by SG, on IP network, send to No. seven protocol adaptation modules of soft switch by crossfire control transmission agreement (Stream Control Transmission Protocol abbreviates SCTP as); At the TG of soft switch node, the PCM voice signal that the PSTN switch sends is converted into the voice packet of RTP encapsulation, transmits on IP network.No. seven protocol adaptation modules in the soft switch parse original IAM message from message, and the inquiry local data base, can find information such as rear subscriber number, user type, address character, caller MSC route; Information such as called number, address character.These all are the input informations of next step preanalysis matching process.
If this calling is to go into the territory by the forward direction soft switch that Session Initiation Protocol links to each other to call out, can also carry the specific call message of appointing between two soft switch by the expansion Session Initiation Protocol, realize that forward office influences the scheme of backward office routing.
Step S604 calls out preanalysis condition matching process (that is, getting the preanalysis template by the longest coupling).
After the input information that has obtained the preanalysis coupling, with carrying out the matching process of calling out the preanalysis technology, promptly carry out preanalysis matching process (that is, above-mentioned steps S406) according to certain input information, this is the committed step in the calling analytical method of the present invention.
Fig. 7 is the schematic diagram according to the calling preanalysis matching condition of the embodiment of the invention, as shown in Figure 7, in the matching process of preanalysis, occurrence, matching relationship, matching value have been formed a complete matching condition, wherein, occurrence is aforesaid calling subscriber's type, caller area code, incoming trunk group number, calling address character, goes into information such as gateway node, called address character; Matching relationship can be in the logical relation: equal, greater than, less than, be not equal to, more than or equal to, smaller or equal to; Matching value is represented the comparison value of occurrence under specific matching relationship.Call out if go into the territory, can also carry the specific call message of appointing between two soft switch, realize that forward office influences the scheme of backward office routing by Session Initiation Protocol by the continuous forward direction soft switch of Session Initiation Protocol.
Among Fig. 7, the matching condition of calling out preanalysis can be one, also can be the combination of above-mentioned multiple information, between each matching condition can in logic " with or, non-" relation.Usually, calling preanalysis is provided with four kinds of different matching conditions simultaneously and can satisfies various minutes source demands, these four matching conditions adopt the list structure storage on the backstage, the calling of input must be satisfied these four kinds of conditions simultaneously and just can be blocked, and can carry out more careful shunting to calling like this and handle.It mainly is that attribute according to caller carries out the branch source that above-mentioned shunting is handled.
The processing mode of calling out the preanalysis matching result generally is to return new number analysis device, and soft switch afterwards can adopt new number analysis device to come current calling is analyzed, and solves the Multiple Area Code Function problem; Can also carry out simultaneously certain FH-number transform operation,, numbers of calling and called parties be carried out FH-number transform promptly according to the preanalysis matching result.
S606 carries out the branch source according to matching result (that is, getting the preanalysis result) and handles (that is above-mentioned steps S408).
After the preanalysis matching condition is mated, will carry out certain processing to the calling of Satisfying Matching Conditions, this is the target of preanalysis technology.Be mainly used in the process that forward office influences the backward office number analysis that solves owing to call out the preanalysis technology, the promptly good according to a preconcerted arrangement correct number analysis device of Information Selection, therefore, the branch source processing mode after the coupling comprises:
A changes number analysis device (that is manipulative indexing).
B carries out FH-number transform (that is, utilizing new digit analysis to carry out FH-number transform) to caller, called number, and transformation results is returned.
In addition, matched specific calling, therefore can also carry out other operations, for example: the numbers of calling and called parties in calling out is carried out standardization, change caller, called subscriber's classification, address character etc. the calling that filters out owing to call out preanalysis.
The essence of calling out the preanalysis technology is according to certain matching condition, and preliminary treatment is carried out in specific calling; And after the call matches success, any information in calling out is carried out editing and processing.Above-mentioned processing mode comprises: change the number analysis device, carry out numbers of calling and called parties conversion etc.In addition, above-mentioned processing mode also comprises carries out editing and processing to other information in calling out, so that satisfy more demands.
After changing correct number analysis device, system can carry out number analysis, select the process of route.
S608 uses the new digit analyzer to carry out number analysis, selection office route.
Step S608 is similar to normal call flow to the call flow of step S612.The new number analysis device of soft switch utilization carries out number analysis to called number, and according to result's (local exchange lands or relayed call) of number analysis with call proceeding to certain user of local exchange or select certain outgoing route to be transferred on other the switch replay call.
S610, call proceeding, called terminal ringing, reply, normal talking.
Called terminal ringing after the replay call, caller/called subscriber listens ring-back/ring back tone to call out respectively; After called party answer, caller and the called double-directional speech that can carry out are conversed.
S612, end of conversation discharges resource, produces charge information.
Behind end of conversation, soft switch discharges various resources, and according to the result of last number analysis, is this call meters according to active user's charging way, and finishes whole call flow in the correct back of chargeing.
Wherein, the matching condition of preanalysis generally adopts calling subscriber's type, caller area code, incoming trunk group number, calling address character, goes into information such as gateway node, called address character.Call out if go into the territory, can also carry the specific call message of appointing between two soft switch, realize that forward office influences the scheme of backward office routing by Session Initiation Protocol by the continuous forward direction soft switch of Session Initiation Protocol.
