NGN can not be in a short time substituting PS TN fully, two networks will long-term co-existence in the quite a long time.In the intercommunication of two networks, call control device is responsible for finishing the conversion between essential signaling from PSTN to IP and from IP to PSTN and the conversation media stream, realizes the intercommunications of two nets.Sharp increase along with IP-based switch quantity, as shown in Figure 1, the a large amount of available call control devices of meeting existence carry out the intercommunication between the network in whole network, might also can exist several call control devices can finish from the NGN network to the intercommunication certain purpose PSTN network switch.Therefore a calling being routed to the PSTN network from IP network usually can pass through considerable call control device and just arrive the final destination.
For the route in the IP network management more flexibly and effectively and reduce from IP network to the individual call of PSTN network the IP network device node number of process, in NGN, introduced location server (LS, Location Server) equipment.The complete IP based network of LS, and preserve and safeguarding that E164 number (at the telephone number that generally uses on the public network) prefix jumps mapping relations between IP address of call control device to next.
Without any the method for preserving the route charge information on LS, LS has only preserved the routing iinformations such as IP address, port and protocol type of the relevant next-hop network equipment of called number prefix but up to the present.When using LS to call out the selection of route in the NGN network, LS has also only comprised the routing iinformations such as IP address, port and protocol type of next-hop network equipment to the response message of the Route Selection request message of call control device.
In sum, at present NGN is without any the charging way relevant with route data, and less than the standard about chargeing at routing call.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of charging method of communication, and realizing providing charging method based on route by LS, further can select different routes according to the charge information of different route correspondences.
The charging method of communication provided by the invention records the different charge information of different route correspondences on the location server LS, when call control device during to the LS request route information, this method may further comprise the steps:
A, call control device send routing information request to LS;
B, LS choose the route of next jumping, and the charge information of selected route correspondence is sent to call control device together with routing iinformation;
C, call control device write down described charge information, and continue to call out to set up communication according to described routing iinformation;
D, after setting up communication, charge according to the charge information that call control device write down of setting up described communication.
Wherein, when carrying out the exchange of routing iinformation between the LS, the charge information of this routing iinformation correspondence is together exchanged together with this routing iinformation.
Wherein, described charge information is the charging index; The charging data record of charging index correspondence is on call control device, and the described step that communication is chargeed of step D comprises: call control device charges to corresponding metering data according to the charging index search.
Wherein, described charge information is the charging index; The charging data record of charging index correspondence is on charge system, and the described step that communication is chargeed of step D comprises: call control device sends to charge system with the charging index; Charge system is chargeed to corresponding metering data according to the charging index search.
Wherein, described metering data comprises the charging segment number.
Wherein, when having the identical next hop address of being routed to of one or more, the described route step of choosing next jumping of step B further comprises: the route of choosing next jumping according to the routing strategy of LS record.
Wherein, described routing strategy comprises: according to the minimum principle of expense, the step of described selection comprises: according to the pairing charge information of described different routes, sorting charge is with minimum route.
Wherein, when the described route of choosing next jumping of step B was a route after the selective polymerization, the charge information of described selected route correspondence was: the charge information of the route after the polymerization that calculates according to the collocation strategy of setting.
Wherein, the collocation strategy of described setting when being averaged expense, described being calculated as: to the calculating of averaging of the charge information of many routes of carrying out described polymerization.
By said method as can be seen, the invention provides preservation is associated with route in LS charge information, realize route is chargeed by these information being sent to call control device or charge system.Specifically, when adopting LS to select route, LS just can return the charging index in to the routing query response message of call control device, call control device or charge system are then obtained detailed charge information according to charging index and local policy and the charging of the calling finished.
At the VOIP network, conversation in the net, the conversation between the different region network can be corresponding with this city, long-distance charging policy, so route is chargeed and can have been adapted to the development of VOIP.And, adopt different routes to take the heterogeneous networks resource, therefore to carry out different chargings more reasonable in IP network for different routes, and the realization of chargeing based on route helps the development of IP network business.
And according to the charge information of local routing of data, LS can use minimum, moderate or the ultimate cost routing policy is called out route according to local policy.Select the priority of route also can report renewal by local number first data configuration by call control device.LS also can use the route that expense is minimum by charge information according to user's needs reference arm.According to the selection under the different demands of expense different choice route implementing user, also can provide the route of different quality to carry out different charging processing with expense in conjunction with situations (route quality is related with expense) such as route are congested.

Embodiment
Referring to accompanying drawing, complete skill scheme provided by the invention is described in detail.
Because all metering datas that need of configuration are very difficult on LS, and metering data may can change along with the time, different business may be used different metering data etc., so the present invention is the different metering data of the different route correspondences of record (as rate etc.) on LS, comprise charging index (ChargeIndex) but write down the pairing charge information of different routes, the pairing charging data record of this charging index is (Charging Detail Record unit can be on call control device, or independent charge system) on the Charging Detail Record unit.When chargeing, correspond to different charging index according to different routing iinformations, and then correspond to the pairing metering data of charging index like this, realize route is chargeed.
Wherein, above-mentioned metering data is except the different route of correspondence, the data that can also be used for the whole network, segment number (CHB for example charges, Charge band), the charging segment number is a cover metering data of whole net definition, and the information that promptly same charging segment number is seen on any one switch on the whole network all is consistent, as what begin to charge second, how many charging rates is etc.
Referring to Fig. 2, the charging method of communication of the present invention is elaborated, wherein, the charge information of route correspondence is meant the charging index in this example.
Step 201: the corresponding relation of different routes of record and different charge index in LS.Multiple modes such as LS can dispose by local data, call control device reports are obtained routing iinformation, and the corresponding charge information of configuration.
Each call control device can utilize TGREP (telephony gateway log-in protocol) or other agreements, and the LS under routing iinformation is registered to goes up (can be with reference to the TGREP draft, the present invention is not described).LS writes down each routing iinformation, and for each route is provided with corresponding charge information, thereby each route data that makes LS go up record all has charge information associated therewith.The routing iinformation content of record can comprise: route/number head and relevant next-hop network IP address of equipment, port, protocol type etc.
In the present invention, on LS, comprise the charging index for the charge information of each route setting, this is to consider that very difficulty is complicated for each route is preserved detailed metering data on LS, if LS goes up the detailed metering data of record, then the change of any charging way all will relate to the change that LS goes up metering data, is unfavorable for safeguarding very much.
Step 202: exchange route data and corresponding charge information between the different LS.
As in the RFC3219 standard, pointing out, can pass through TRIP (the phone routing mechanism of IP carrying) exchanging routing information between the LS.Among the present invention, the TRIP agreement is expanded, increased " charge information " field, be used to write down the charging index of routing iinformation correspondence, thereby, when LS carries out the exchange of routing iinformation, the charging index of route correspondence together can be sent to other LS.TRIP agreement and increase are at the attribute information of this " charge information " field, and this attribute information (Charge InformationAttribute) can comprise following content:
Conditional Mandatory:False (whether mandatory-attribute: not);
Required?Flags：Not?Well-known。(required argument: do not have);
Potential?Flags：None。(optional parameters: do not have);
TRIP Type Code:To be assigned by IANA (TRIP type code: treat that IANA distributes).
And the form of described " charge information " field (Charge Information Syntax) can be made up of Length (length) and ChargeIndex (charging index).Wherein length field is the byte number of charging index.When the span of charging index (ChargeIndex) was 1-255, length field was 1.If need more charging index (ChargeIndex), can take two bytes or multibyte more, the modification that length field is then corresponding.The Route Metric that different charging index is corresponding different can be 1 o'clock as the charging index according to the height of index size expression Route Metric, and the corresponding Route Metric of expression is minimum.
Here need to prove, the field of above-mentioned TRIP expansion also not only is used for exchange route data and corresponding charge information between the LS, when every needs carry the charging index, can use above-mentioned " charge information " field to carry, the back illustrates no longer separately.
Step 203: in calling procedure, receive the routing information request of call control device as LS after, LS is the address that call control device is selected next jumping, promptly selects a route and comes.LS carries the charging index (ChargeIndex) of selected route correspondence in response message when returning the route requests response to call control device.
When LS is call control device selection route, can also select according to the charging index.For example, when many routes can arrive same destination device, and when routing strategy is " the minimum policy attribute of expense ", then can be by charging index size (how much relevant the size of charging index and Route Metric be) the minimum pairing route of the expense of determining of judging different route correspondences.Specifically can have route can arrive final purpose equipment, but the metering data on each bar route be different referring to example shown in Figure 3 through three different call control devices.Article one, the charging index of route data is 1, and the charging index of second route data is that the charging index of 2, the three route datas is 3.The expense of route 1 is minimum, secondly is route 2, and the expense of route 3 is the highest.When selecting route so according to the method described above, then select article one route as selected route.
In addition, when many route aggregations were one, during for the chargeing of the route after such polymerization, LS can be that route data after the polymerization is provided with a suitable charging index according to institute's configured strategy.For example, the LS configured strategy is when being averaged expense, and then the algorithm of averaging and calculating and round at the charging index of described many routes obtains the index data that charges.For example 0101, several different route aggregations of 0102-0109, these route charging index are respectively 1～9, then according to described strategy, the charging index that obtains the route after the polymerization is | (1+2+ ... + 9)/9|=5.
Step 204: when set up call out after, when communication is chargeed, according to the pairing metering data of charging index (as the rate etc.) processing of chargeing.
Processing is carried out on the call control device of the source of the side of making a call if charge, then routing iinformation that relates in the calling procedure and charging index all will send on the call control device of source, by the metering data of source call control device, to calling out the route processing of chargeing according to the charging index correspondence of its record.
If exist independently charge system, then routing iinformation that relates in the calling procedure and charging index all send to charge system, by the charge system unification processing of chargeing.For example, when a calling procedure process call control device 1, call control device 2, call control device 3, related charging index all sent charge system to and carries out same charging and handle during this of record called out respectively on each call control device, realized the charging to the whole process of this calling.Certainly, average again after also can calculating actual expense respectively.
Charging way of the present invention has realized the charging at route, can be widely used among the IP-based NGN.For example, when being applied in the VOIP network, conversation in the net, the conversation between the different region network can be corresponding with this city, long-distance charging policy, that is to say, route between the route of network, different region can be corresponding with this city, long-distance charging policy, thereby realize the communication charge under the VOIP network.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
