Description
Technical field
The present invention relates to the communications field, relate in particular to the method and the device of call route selecting.
Background technology
Present call route selecting technology is, a calling is chosen routing number according to route selection source code and routing code query routing analytical table, comes the chooser route by routing number then, selects trunk group again under this sub-route after choosing sub-route.
Select the mode of a sub-route to have three kinds under the present route: in order selection, precentagewise are selected and at cost size selection.Select in order: according to the select progressively sub-route from the 1st sub-route to the n sub-route, sub-route need not grouping.When the 1st sub-route (through sub-route) is no-trunk or unavailable, select the 2nd sub-route, the rest may be inferred; Precentagewise is selected: divide into groups according to percentage, the order from the 1st sub-route to the n sub-route is adopted in grouping, sub-route percentage sum equals 100% continuous sub-route and is divided into one group, and precentagewise realizes the load sharing of sub-route in the group, then selects in order between group.For example: the 1st sub-route is the 1st a group of sub-route, its load sharing is 100%, 2nd, 3 sub-routes are the 2nd group of sub-route, and load sharing is: the 2nd sub-route is that 50%, the 3 sub-route is 50%, select the 1st group of sub-route during Route Selection at first in order, when the 1st group of sub-route is no-trunk or unavailable, select the 2nd group of sub-route, carry out load sharing by the 2nd sub-route and the 3rd sub-route, adopt the percentage selection mode, percentage is respectively 50%, 50%; Select at cost: on cost carry out Route Selection, the sub-route quilt that cost is minimum is preferred, when this sub-route is no-trunk or unavailable, be chosen to this low sub-route, the rest may be inferred, if the cost of a few strip routes is identical numerical value, then between these a few strip routes, select according to the percentage selection mode.
But the mode of above-mentioned three kinds of chooser routes all can't be judged the carrying quality situation under the speech channel of choosing, so just cause a problem, if the poor quality of carrying under a certain strip route, has only the normal and called connection of calling energy of fraction, for example under new environment, a large amount of signalings uses grouping such as IP (Internet Protocol, Internet protocol) transmits, if the route carrying is of poor quality, IP transmits, and packet loss may take place, the problem that will cause call loss and exist signaling to transmit.If this sub-route is still selected in follow-up calling, the connection possibility of this subsequent voice calls will be lower so.

Embodiment
With reference to figure 1, under this networking example, there is many strips route in Calling Side A office between callee side B office, there is shown two strip routes, wherein R1 is through sub-route (DirectRoute), promptly do not have directly to arrive through other exchanges the route of opposite end, R2 is circuitous sub-route (BypassRoute), promptly through arriving the route of opposite end after other exchanges.When dialing the d user of B office, a user of A office have two sub-routes to select, if current calling is carried by through sub-route, the number of times M1 that makes a call on the through sub-route of A office record behind the connection d user increases once, and access success connection times N 1 also increases once on the through sub-route; For a certain reason, the d user of B office is not connected in a user's calling, and at this moment A office only records through sub-route and makes a call number of times M1 increase once, and circuitous sub-route access success connection times N 1 does not increase.If current calling is carried by circuitous sub-route R2, make a call number of times M2 and the access success of circuitous sub-route are connected times N 2 also adopt similar computational methods.
Wherein, each sub-route sending-down is played the number of times of calling, can behind Route Selection success back (sub-Route Selection success back or trunk group select successfully after) calculating or call through/access failure, calculate.Number of times is successfully connected in each sub-routing call to be calculated behind call through.For the percept of call completed of sub-route, can calculate in the following moment: 1) calculate after T cycle time that sets is overtime, this cycle can be adjusted by order; 2) upgrade percent of call completed after any number of times that makes a call changes; 3) any access success is connected and is upgraded percent of call completed after number of times changes.
Along with the increase of the number of calls, A office can calculate the percept of call completed of each sub-route like this: the percent of call completed CR1=N1*100/M1 of through sub-route, the percent of call completed CR2=N2*100/M2 of circuitous sub-route.By calculating the percept of call completed of each sub-route, can demonstrate the carrying quality situation of each sub-route.
When having subsequent voice calls to initiate, A office according to configuring condition, selects the sub-route of carrying optimal quality according to the sub-route percent of call completed CR1 and the CR2 that calculate, perhaps chooser route pro rata.The route of chooser pro rata here is meant: according to the percentage of sub-route R1 and sub-route R2 chooser route recently, as working as CR1 is 80%, CR2 is 90% o'clock, and the percentage of at this moment choosing sub-route R1 is 80/ (80+90), and the percentage of choosing sub-route R2 is 90/ (80+90).So that the higher sub-route of percent of call completed can access more calling selection, the sub-route that percent of call completed is lower obtains less calling and selects like this.
With reference to figure 2, under this networking example, after a route or sub-route were selected to the calling between the callee side B office by Calling Side A office, this route or sub-route can have polytype relaying, also can only have one type relaying; The relaying of one group of same type concentrates in the group and manages, and might as well claim that this group is trunk group.This strip route has two trunk groups among the figure.When dialing the d user of B office, a user of A office under this sub-route, have two trunk groups to select, if current calling is by first trunk group (G1) carrying, A office records this trunk group G1 and makes a call number of times MG1 increase once behind the connection d user, and this trunk group G1 access success is connected times N G1 to be increased once; For a certain reason, a user calls out and does not connect the d user of B office, and at this moment A office only records this trunk group G1 and makes a call number of times MG1 increase once, and this trunk group G1 access success is connected not increase of times N G1.If a user of A office dials the d user of B office and selects second trunk group (G2), make a call number of times MG2 and the access success of second trunk group are connected times N G2 also adopt similar computational methods.
Equally, to the number of times that makes a call under each trunk group, can select to calculate behind successfully back calculating or the call through/access failure at trunk group.Each trunk group access success is connected number of times to be calculated behind call through.For the percept of call completed of trunk group, can calculate in the following moment: 1) calculate after T cycle time that sets is overtime, this cycle can be adjusted by order; 2) upgrade percent of call completed after any number of times that makes a call changes; 3) any access success is connected and is upgraded percent of call completed after number of times changes.
Along with the increase of the number of calls, A office can calculate the percept of call completed of each trunk group: the call completing rate CG1=NG1*100/MG1 of first trunk group, the call completing rate CG2=NG2*100/MG2 of second trunk group.By calculating the percept of call completed of each trunk group, can demonstrate the carrying quality condition of each trunk group.
When having subsequent voice calls to initiate, A office according to configuring condition, selects the trunk group of carrying optimal quality according to the trunk group percent of call completed CG1 and the CG2 that calculate, perhaps selects pro rata trunk group.The trunk group of selection pro rata here is meant: the percentage according to trunk group G1 and trunk group G2 is recently selected trunk group, as working as CG1 is 80%, CG2 is 90% o'clock, and the percentage of at this moment choosing trunk group G1 is 80/ (80+90), and the percentage of choosing sub-route G2 is 90/ (80+90).So that the higher trunk group of percent of call completed can access more calling selection, the trunk group that percent of call completed is lower obtains less calling and selects like this.
