Embodiment
With embodiment the present invention is described in further detail with reference to the accompanying drawings below:
The present invention adopts Smart Home Location Register (SHLR) to realize the Wide Area Centrex business, and its basic skills is exactly to make full use of the centralized management function of SHLR to user data, preserves WAC user's long and short mapping relations on SHLR; Soft switch mutual by with SHLR obtains caller cornet and called trombone information, then called trombone carried out number analysis, finally locatees calledly, just can realize WAC user's cornet IWF.On data configuration, WAC user's the long and short table of comparisons is concentrated and is kept among the SHLR, manages concentratedly; Still need in the soft switch to dispose Centrex group's data, but Centrex user can not dispose the cornet data, also can dispose the cornet data, if disposed cornet, then the cornet with soft switch this locality is as the criterion.When caller is dialled called cornet and is carried out the WAC intra-group call, if the soft switch local search, need arrive the trombone that SHLR goes up inquiry cornet correspondence less than the trombone of cornet correspondence.When WAC user goes out groupcall,, also need the cornet of SHLR inquiry trombone correspondence, so that the cornet of record caller in the ticket if this locality does not dispose cornet.
In networking, the mode of exchange visit SHLR has two kinds: a kind of is that end office (EO) directly visits SHLR, as shown in Figure 1, is called end office's mode; Another kind is that all WAC of end office (EO) call out or all-calls is routed to tandem exchange, by the visit SHLR of tandem exchange, is called tandem exchange's mode, as shown in Figure 2.End office (EO) does not need to do the Centrex data under tandem exchange's mode, is applied to the occasion that end office's inconvenience is transformed.If the WAC of end office (EO) customer call, according to the calling number differentiation, judge whether to WAC user and obtain the WAC user data in the tandem exchange, carry out the Centrex number analysis then.And in being arranged on the called number analytical table of soft switch inside, will increase the WAC analysis mark, to carry out called WAC according to this sign for incoming call analyzes, with what judge whether to call out is the WAC user of band edge office of institute under this tandem exchange, promptly determine called whether WAC user, so that carry out the Centrex caller ID display.
Below divide several situations to describe call flow in detail:
No matter be end office's mode or tandem exchange's mode, SHLR comprises two kinds of situations to the handling process of WAC business---WAC intra-group call business and WAC go out the groupcall business.WAC intra-group call business may further comprise the steps as shown in Figure 3:
SHLR supports according to calling number, called cornet inquiring calling cornet, called trombone;
L1: soft switch sends in SRI (Send Routing Info---the transmission routing iinformation) message of SHLR, carries caller trombone and called cornet, and insert WAC intra-group call service access code before called cornet;
L2:SHLR identifies this time according to service access code that inquiry is WAC intra-group call business, and the prefix that this is special obtains caller cornet, group number according to the caller trombone, and obtains behind the called trombone these information to be returned to soft switch according to group number and called cornet.
WAC goes out the groupcall business as shown in Figure 4, may further comprise the steps:
Centrex realm type under the Centrex user is SHLR mode WAC, and there is not cornet, then when making a call, soft switch sends and carries calling number, preceding slotting WAC goes out the SRI message of groupcall service access code+called number to SHLR. inquiring calling cornet;
SHLR discerns to WAC and goes out the groupcall service access code, searches the cornet of calling number correspondence, returns cornet that inquires and the called number of having deleted service access code in SRI_ACK message.
Its data configuration of call flow under end office's mode is, local exchange still keeps the Centrex data, but needs to increase new WAC realm type (SHLR mode WAC), and such WAC group user need not dispose the cornet data at local exchange.Other data of Centrex group still keep as outgoing prefix, cornet prefix and length (The Minimum Number Length of cornet prefix, maximum number length are consistent), Centrex new business prefix.
The mode local exchange WAC of end office (EO) intra-group call flow process comprises the steps: as shown in Figure 5
The user dials the cornet calling in the group, and soft switch sends and carries the SRI message of calling number, WAC intra-group call service access code+called cornet to SHLR;
SHLR returns caller cornet, called trombone;
Soft switch judges it is the local exchange number according to called trombone, locate called and makes a call, carry in the message related to calls caller trombone, group number and the caller cornet;
Callee side judges it is incoming call in the group, and caller ID display is a cornet.
The out WAC intra-group call of end office's mode flow process comprises the steps: as shown in Figure 6
Under end office's mode, user A dials the user B that cornet is called out another exchange in the local exchange group, and the SRI message that calling number, WAC intra-group call service access code+called cornet are carried in the soft switch transmission is to SHLR, and SHLR returns caller cornet, called trombone;
This called number of flexible exchange analysis is an outbound call, use the ISDN User Part (Integrated Services Digital Network User Part/ISDN User Part---SDN User Part) of expansion to initiate outbound call, except that caller trombone, called number, the ISUP of this expansion uses the universal number unit to carry caller cornet (ISUP expansion at present be not with group number);
Support the same expansion of ISDN User Part if play a game, caller ID display is a cornet.If do not support, then caller ID display is trombone (plays a game and can be shown as outgoing prefix+trombone).
The mode WAC of end office (EO) goes out the groupcall flow process as shown in Figure 7, comprises the steps:
End office's mode, WAC user transfers to group prefix+called number to make a call.End office (EO) is identified as out groupcall, if there is not the caller cornet, need to send message to SHLR inquiring calling cornet (will need the caller cornet in the ticket), soft switch sends and to carry calling number, gives SHLR with the SRI message of the called number (not taking group prefix out of) of special prefix, and SHLR returns caller cornet, called number;
Soft switch makes a call to called, carries the caller trombone.
Its data configuration of call flow under tandem exchange's mode is, WAC under tandem exchange's mode, band edge office of institute of tandem exchange (C5 office) still keeps Centrex group's data, data and end office's mode in the tandem exchange (C4 office) are basic identical, different is to need to do WAC user data in the C5 office (but not needing cornet) in the C4 office, and to the trunk group yard differentiation of calling out the numbers of deciding, identification WAC user.
Other WAC user of C5 office flow processs of the WAC of C5 office customer call comprise the steps: as shown in Figure 8 under tandem exchange's mode
The user of C5 office dials cornet and calls out, C4 office in callings, and C4 office is according to calling number and go into the differentiation of relaying calling number, and judging is WAC user, and number long according to the first cornet judgement cornet;
C4 office collects short back number, returns ACM (Address Complete Message) for C5 office, and the SRI message of called cornet that sends and carry the caller cornet, adds special prefix is to SHLR;
SHLR returns SRI ACK (SRI response message) message, carries the caller cornet, called trombone;
The soft switch of C4 office is according to called trombone, and judging called is the C5 intra-office subscribers, makes a call to this user, uses the ISDN User Part of expansion when out, carries caller trombone and cornet; If do not support the ISDN User Part expanded when out, then C4 office can select the caller cornet is sent to called end office as calling number according to data configuration, perhaps the caller trombone is sent to called end office as calling number.。
The trombone or the cornet of the caller ID display caller of sending here according to C4 office in the C5 office.
The WAC user of C5 office goes out the groupcall flow process as shown in Figure 9 under tandem exchange's mode, comprises the steps:
The user of C5 office transfers to group prefix to call out, and calls out and is routed to C4 office;
C4 office is by the calling number differentiation, and identification is that caller is WAC user, and does number analysis, and identification is groupcall.To SHLR inquiry cornet, SHLR returns the caller cornet then;
Behind the C4 office deletion outgoing prefix, analysis is an outbound call, makes a call to other offices, carries the caller trombone.
The outer incoming call C5 WAC user of the office flow process of WAC group comprises the steps: as shown in figure 10 under tandem exchange's mode
Because C4 office on the C5 office all-calls, C5 office externally do not have independently route, his incoming call C5 office of office all passes through C4 office;
C4 office inserts special prefix before calling number after, to SHLR inquiring calling cornet, SHLR returns the caller cornet;
C4 office inserts special prefix before calling number after, to SHLR inquiring calling cornet, SHLR returns the caller cornet;
It is the WAC user of C5 office that C4 office judges called, and called and caller distinct group, and then C4 office sends the caller trombone according to data configuration to C5 office, perhaps adds called Centrex group's outgoing prefix as calling number before the caller trombone.
Be understandable that, for those of ordinary skills, can be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, and all these changes or replacement all should belong to the protection range of the appended claim of the present invention.
