Description
Technical field
The present invention relates to IMS (IP Multimedia System) and the LTE voice industry based on IMS
Business (VoLTE) technical field, more particularly to a kind of method for realizing called number completion,
VoLTE terminals, base station and system.
Background technology
VoLTE is that at the beginning of 2010, institute is really as the GSMA of global mobile operator alliances
The standard scheme of fixed LTE voices.In VoLTE schemes, built-in support VoLTE chips
Primary terminal be attached to after LTE wireless networks and EPC core nets and access telecom operators
IMS network, core control network of the IMS network as VoLTE, completes VoLTE languages
The Call- Control1 of sound, traffic route and business triggering.
In IMS network, the E.164 number (Global based on called global format is called
Number) carry out routing addressing.For mobile number, global number form is (national code)
+ (network No.)+(H0H1H2H3)+(ABCD)；For fixed number, global number lattice
Formula is (national code)+(area code)+(local number).
In order to keep the concordance of subscriber dialing custom and business experience, VoLTE terminals prolong
Continue the dialing rule of existing 2/3G mobile phone terminals：The dial mode of calling fixed number is local number
Code/(trunk prefix)+(area code)+(local number), calls the dial mode of mobile number
For (network No.)+(H0H1H2H3)+(ABCD), not global number.Now for IMS
The needs of middle correct route, just must carry out completion to the national code and area code in called number.
During the present invention is realized, inventor has found that the area code of the callee in existing IMS is mended
At least there are the following problems for full technology：
IMS network follows the separation of Call- Control1 and Service control, and modification number belongs to business work(
Can, it is impossible to be placed on Call- Control1 network element CSCF and realize, the ownership place control of IMS in addition
Attribute, 3GPP propose to arrange called number completion application server by ownership IMS network
The scheme of (Application Server, AS)：The service edge Access Control accessed by user
(BAC) increase in the Request-URI of user's call request INVITE
Phone-context domains carry national code and area code information, and by ownership place IMS network number
Completion AS's completes called number completion according to phone-context.Such as Beijing user roaming
To Shanghai, 50440045 numbers are dialed, Request-URI is sent for " Tel：50440045”
INVITE, and can increase wherein after Shanghai BAC receives the message and carry state
The phone-context parameters of family's code and Shanghai area code+8621, now INVITE
Request-URI is " Tel：50440045；Phone-context=+8621 ".IMS network
The INVITE is route, returning to ownership place carries out business triggering, by ownership place
Number completion AS carries out called number completion according to phone-context parameters, is formed
Request-URI is " Tel：+ 862150440045 " INVITE, so as to incite somebody to action
INVITE is routed to 50440000 user of Shanghai.Implement and see accompanying drawing 1.
But this scheme requires that BAC must be deployed in local aspect, such deployment way pole
Big increase cost, so not used by actual networking.In the actual networking of IMS, BAC
Generally by the way of concentration deployment is saved, a BAC corresponds to the access of multiple LANs to equipment,
In this case, BAC cannot be distinguished by terminal and access from which LAN, also just cannot be
Corresponding area code is filled in phone-context.Therefore, at present with fixed network access based on
In IMS network, such scheme is not adopted completely, although deploy the AS of number completion,
But the foundation of called number completion is according to caller national code and area code information.This is because fixed
Terminal does not possess roaming characteristic, when which transfers to local number, it is meant that to be continued is
With the user of LAN, now supply and caller identical national code and area code in called number
It is feasible.But, for the VoLTE terminals for possessing roaming characteristic, such scheme is deposited
In obvious defect.
In existing 2/3G technologies, when mobile terminal carries out roaming call, if dialled fixed number
Code is the local number form for not carrying area code, and roaming mobile switching centre (MSC) can root
According to user base station controller (BSC) office to (BSC is local disposition) by the area code of roaming place
Mend before called number, routing keeping roaming place number.Based on the continuity of user's use habit,
This Dialing Method and business experience can be continued up in VoLTE business.If based on
The upper fixed number complementing method for accessing IMS, supplies called number according to caller information, non-unrestrained
Trip scene under called number can correctly completion, but under roaming scence, user dials local number
When, no matter terminal roaming is where, called number completion can be all master home by IMS network
The area code on ground, continue ownership place number, and it is roaming place number that now user wishes to continue originally
Code, so as to cause the generation of roaming call route mistake.Such as Beijing VoLTE user roaming
To Shanghai, 50440045 numbers are dialed, it is desirable to which continue 50440045 user of Shanghai, but base
In supplying called rule according to caller, IMS network will will be by according to the H codes of Beijing user
Code of calling out the numbers is supplied as+861050440045.If Beijing equally exists 50440045 numbers,
The user that continues causes routing error；If there is no the number, call failure in Beijing.
Except problem above, the existing number completion scheme based on AS needs ownership place IMS nets
The all-calls that terminal is initiated are routed to number completion AS in the way of business triggering by network, and this is not
Only there is high requirement so as to cause equipment cost to increase to the performance of AS, can also elongate and exhale
Cry the path of route.Meanwhile, the triggering to AS is called to complete user, in addition it is also necessary to for each
The iFC of one number completion of user configuring, guides call diversion to number completion AS with iFC,
User data configuration amount is very big, also increases the expense of home signature user server HSS.
Although the IMS called number completion technologies provided by i.e. 3GPP can be realized according to end
The accessing position information at end supplies called number, but its specific BAC deployed with devices is required not
Meet the actual networking plan of operator；And adopted during the actual networking of operator according to caller
Information supplies the method for called number because area code of the callee can only be supplied for ownership place area code, nothing
Method is applied to the mobile terminal for possessing roaming characteristic.Meanwhile, supplied based on the called number of AS
Method also brings lower deployment cost, complicated data configuration and the call routing of high-performance equipment roundabout.
