The present technique field personnel know, CENTREX is an elemental user group with local exchange top user definition in fact exactly, and the user in this customer group not only has common local user's all functions, and has PABX (private branch exchange) function.Therefore CENTREX user has two numbers: a trombone (being common Local Number) and a cornet (number in the group), and long cornet is also deposited, but group's word of foreign origin distinctive ringing in the group.The CENTREX basic service mainly contains:
1. intra-group call: directly dial in the group extension or go to another extension set by telephone operation machine.
2. in the outer incoming call of group was exhaled: the outer user of group can dial directly group Local Number of interior arbitrary extension set (trombone); Also can go to group interior extension set by certain CENTREX group's operator.
3. breathe out in the group to the group: transfer to the numeral hat to dial any public network number (going out group mode has multiple) more earlier; Or go to outside line by the operator.
At the CENTREX business characteristic, the present invention stores CENTREX group's data configuration relevant with number in advance, automatically generate each CENTREX group's number figure and leave in the SoftSwitch, when judgement behind user's off-hook is CENTREX group user, can obtain CENTREX group user number figure accurately, and it is handed down to gateway, make gateway can when subscriber dialing, give response exactly.
In order to make those skilled in the art person understand the present invention program better, the present invention is described in further detail below in conjunction with drawings and embodiments.
With reference to Fig. 1, Fig. 1 is an applied environment schematic diagram of the present invention:
Wherein, user 1 and user's 2 telephone set links to each other with gateway 2 with gateway 1 respectively, by SoftSwitch gateway is controlled.When the user inserts, need gateway to collect and dial the number to the SoftSwitch report of user.
Fig. 2 shows the realization flow of the inventive method, may further comprise the steps:
Step 201: configuration virtual subscriber exchange CENTREX group Subscriber Number is analyzed data on SoftSwitch.
Can adopt multiple mode to be configured, such as, by man-machine interaction mode, file mode, be about to configuration data and write a text or pass through WEB mode etc.
According to the CENTREX business characteristic, CENTREX group's Subscriber Number that dispose is analyzed data and is comprised: CENTREX group's outgoing prefix descriptor, CENTREX group's console configuration information, CENTREX group number analytical information etc.
Step 202: when SoftSwitch starts, analyze the number figure that data generate corresponding each CENTREX group automatically according to CENTREX group's Subscriber Number of configuration.
SoftSwitch is searched CENTREX group's number figure for convenience, can set up a CENTREX group in advance and count the index of the picture table on SoftSwitch, makes this table comprise information such as CENTREX group identification, number figure storage address.
After SoftSwitch starts, scan each CENTREX group's Subscriber Number successively and analyze data, generate corresponding CENTREX group and count figure; Then the CENTREX group who generates being counted figure is stored in respectively in the memory address that CENTREX group counts this CENTREX group identification correspondence in the index of the picture table.
Also can in the memory of SoftSwitch, reserve certain memory space, after SoftSwitch starts, scan each CENTREX group's Subscriber Number successively and analyze data, generate corresponding CENTREX group and count figure; Then the CENTREX group who generates is counted figure and write in the memory block that reserves, the initial address that writes according to each CENTREX group generates corresponding CENTREX group and counts the index of the picture table simultaneously, and is same, and this table comprises information such as CENTREX group identification, number figure storage address.
Receive CENTREX group user's off hook signal at SoftSwitch after, can count the memory address that the index of the picture table finds corresponding several figure, thereby read this number figure according to this CENTREX group.
Step 203: receive CENTREX group user's off hook signal when SoftSwitch after, discern the affiliated CENTREX group of this user.
Step 204: retrieval CENTREX group counts the index of the picture table, obtains the memory address of the corresponding number figure of the affiliated CENTREX group of this user;
Step 205: obtain the number figure in the memory address and be handed down to gateway.
Step 206: gateway is according to the number figure control user's who receives dialing.
Because issued number figure accurately to gateway, like this, gateway just can be given corresponding response exactly when subscriber dialing.Such as, when the user transfers to prefix,, can hear secondary dial tone immediately if support secondary dial tone; Simultaneously, can make SoftSwitch can carry out the number analysis and the processing that continues according to the accurate reporting information of gateway.
In the present invention, because number figure generates automatically according to system configuration data, therefore, when reconfiguring the number analysis data, can influence the structure of number figure, such as, increase a group newly or reduce by a group, perhaps variation has taken place in Qun number analysis characteristic, at this moment, need read CENTREX group's number related information again, generate the also number figure of updated stored.
The renewal that CENTREX group counts figure can be restarted by SoftSwitch and finished:
After reconfiguring CENTREX group number analysis data, restart SoftSwitch, scan each CENTREX group's Subscriber Number successively and analyze data, generate corresponding CENTREX group and count figure; Then the CENTREX group who generates being counted figure stores respectively in the corresponding memory address.
CENTREX group counts the renewal of figure and can also finish in real time in the SoftSwitch running:
A flag bit is set, in the SoftSwitch running, if the CENTREX group number changes after analyzing data, then with this flag bit set, after system detects this flag bit, scan each CENTREX group's Subscriber Number again successively and analyze data, generate corresponding CENTREX group and count figure; Then the CENTREX group who generates being counted figure stores respectively in the corresponding memory address; Remove this flag bit then.
Describe CENTREX group below for example in detail and count the figure generative process.
Example 1:
It is as follows that the CENTREX group number is analyzed data:
(1) CENTREX group's outgoing prefix descriptor, such as: groupcall is expressed in dialing 0;
(2) CENTREX group's console configuration information, such as: console is represented in dialing 9;
(3) CENTREX group number analytical information, such as: suppose that group interior user number length is 5, and all with 5 or 6 beginnings.
Arthmetic statement is as follows: the outgoing prefix that at first number obtains this group according to CENTREX group, be 0 above, the first that then generates number figure is " 0| ", number obtain the console prefix of this group then according to CENTREX group, be 9 above, the second portion that then generates number figure is " 9| ", the called number that number obtains this group according to CENTREX group is analyzed data again, scanning one by one, according to group's number length and prefix information, generating two number figure respectively is " 5xxxx| " and " 6xxxx| ", and all several figure are stitched together becomes CENTREX group's number figure " 0|9|5xxxx|6xxxx " at last, it is kept in the database, waits for and be handed down to gateway when this group user carries machine.
After SoftSwitch starts, system group one by one reads three partial informations of foregoing description, according to the several rule maps among the RFC3435, and the number analysis rule of soft switch, as The Minimum Number Length of specific number head etc., the rules that the analysis of accurate generation soft switch number needs etc. generate the figure that counts that is correlated with automatically, leave number figure in and store in the space.
After number figure generated, when first number of subscriber dialing was 6, gateway need wait for that it dials 4 numbers again, just can report SoftSwitch.
Example 2:
It is as follows that the CENTREX group number is analyzed data:
(1) CENTREX group's outgoing prefix descriptor, such as: groupcall is expressed in dialing 0;
(2) CENTREX group's console configuration information, such as: console is represented in dialing 9;
(3) CENTREX group number analytical information, such as: suppose group interior Subscriber Number with 3 beginnings, number long is 5, and number is with 6 beginnings, and number long is 7, and number is with 82 beginnings, and number long is 8.
Arthmetic statement is as follows: the outgoing prefix that at first number obtains this group according to CENTREX group, be 0 above, the first that then generates number figure is " 0| ", number obtain the console prefix of this group then according to CENTREX group, be 9 above, the second portion that then generates number figure is " 9| ", the called number that number obtains this group according to CENTREX group is analyzed data again, scanning one by one, number length and prefix information according to the group, generating two number figure respectively is " 3xxxx| " and " 6xxxxxx| ", " 82xxxxxx| " is stitched together all several figure at last becomes the number figure that CENTREX group's number figure " 0|9|3xxxx|6xxxxxx|82xxxxxx " becomes the group, be kept in the database, wait for and be handed down to gateway when this group user carries machine.
After SoftSwitch starts, system group one by one reads three partial informations of foregoing description, according to the several rule maps among the RFC3435, and the number analysis rule of soft switch, as The Minimum Number Length of specific number head etc., the rules that the analysis of accurate generation soft switch number needs etc. generate the figure that counts that is correlated with automatically, leave number figure in and store in the space.
After number figure generates, when first number of subscriber dialing is 6, gateway need wait for that it dials 6 numbers again, just can report SoftSwitch, if and the user begins two dialing is 82, then gateway can wait for that equally still the user dials 6 numbers again and just can report SoftSwitch and carry out next step analysis.
Like this, SoftSwitch is counted figure by generating and storing CENTREX group automatically, will give gateway to digital-image sending that should the user when subscriber dialing, by gateway the number that the user dialled is filtered in advance, has improved whole networks efficiency.
With reference to Fig. 3, Fig. 3 is the flow chart that the present invention controls subscriber dialing:
1. the user carries machine;
2. gateway is carried the machine reporting events with the user and is given SoftSwitch;
3. SoftSwitch is analyzed the information of reporting of user, finds that the user is CENTREX group user, then number gives the database of soft switch the group, to obtain this CENTREX group's number figure;
4. soft-switch database obtains the number figure that generates according to CENTREX group's data configuration in advance, returns to the soft switch call treatment;
5. soft switch is given gateway with digital-image sending;
6. gateway is put dialing tone to the user, reminds the user to dial;
7. gateway echoes to soft switch and answers;
8. subscriber dialing;
9. the numbers conform of dialling in as the user is counted the dialing rule of figure definition or when overtime, gateway reports dialing information to soft switch.
Though described the present invention by embodiment, those of ordinary skills know, the present invention has many distortion and variation and do not break away from spirit of the present invention, wish that appended claim comprises these distortion and variation and do not break away from spirit of the present invention.
