With reference to figure 1, in the embodiment of the invention one, current scene is that circuit domain AS user makes a call as the calling subscriber, realizes that the method that the embodiment of the invention one is provided can may further comprise the steps:
Step 101:MSC sends the location registers notification message to HLR, wherein carries to be used to represent oneself whether to support that IMS triggers the parameter information of ability.
When MSC supports that IMS triggers ability, then when circuit domain AS user need carry out location registers, for example, during mobile terminal-opening, when perhaps the position is moved, the MSC at the current place of this circuit domain AS user sends location registers notification message (REGNOT, Registration Notification INVOKE) to HLR, wherein carries to be used to represent oneself whether to support that IMS triggers the parameter information of ability.In the present embodiment, this parameter information can be represented flexibly, represent when for example in parameter information, establishing set in advance that IMS triggers the support of ability, represent that with " 0 " MSC does not support IMS to trigger ability, perhaps carry special parameter and express support for IMS triggering ability, do not carry this special parameter and represent not support IMS to trigger ability; Certainly, also can adopt other modes of between HLR and MSC, arranging to realize this parameter.
Step 102:MSC receives the location registers push-notification-answer message of carrying the IMS trigger information that HLR returns.
In the present embodiment, when MSC supports the triggering ability, HLR returns the location registers push-notification-answer message (regnot) of carrying the IMS trigger message to MSC, wherein, described location registers notification message and location registers push-notification-answer message are MAP message, the english abbreviation REGNOT of capitalization represents request message, and the english abbreviation regnot of small letter represents response message.HLR can determine whether add the IMS trigger message in this location registers push-notification-answer message according to the MSC ability.
Described IMS trigger information can comprise in actual applications: IP address information or entity identification information, described IP address information specifically can comprise the IP address of the interface entities of the IP address of AS or IMS, described entity identification information can comprise the interface entities sign of AS sign or IMS again, such as, entity identification is its domain name.
Step 103: when this circuit domain AS user made a call, the IMS trigger information of carrying in the location registers push-notification-answer message that MSC returns according to attaching position register HLR was called out route.
When circuit domain AS user made a call, whether MSC need receive the IMS trigger information by judging oneself, and whether obtain this user who makes a call is circuit domain AS user's information.Concrete, MSC judges oneself to have received the IMS trigger information that HLR returns that then MSC can learn that this user who makes a call is circuit domain AS user by before receiving this circuit domain AS Client-initiated initial call request message.
Wherein, concrete, the process that MSC calls out route can route the call to the interface entities of IMS for: MSC according to the interface entities sign of the IP address of the interface entities of described IMS or IMS; Wherein, the IP address information of the interface entities of IMS can be the IP address information of I-CSCF; Perhaps, the IP address of the aforesaid AS of MSC foundation or AS sign are routed to AS with this circuit domain AS user's calling; Need to prove, when not having the IP address information, can be in advance at the corresponding relation of MSC configuration entity identification and IP address, then follow-uply just can obtain corresponding IP address according to entity identification, route the call to interface entities or the AS of the IMS of correspondence.When entity identification is domain name, also can obtain the IP address of domain name correspondence by external dns server.
Need to prove, in the present embodiment, can HLR support the IMS triggering ability except know MSC by the parameter information in the location registers notification message that receives MSC, can also be MSC configuration IMS trigger ability at HLR in advance, then at this moment, for example, support the IMS trigger message, then need not MSC and in the register request message of position, carry the parameter information that is used to represent whether to support IMS triggering ability if disposed MSC at HLR in advance.Described HLR is signatory simultaneously IMS trigger information of described circuit domain AS user and intelligent contactor information.When circuit domain AS user called out, when MSC support IMS trigger ability, MSC was called to IMS (or AS) according to described IMS trigger.When circuit domain AS user calls out, when MSC does not support the IMS ability, carry out intelligent trigger according to described intelligent contactor and handle, the intelligence number of changing by SCP is called to IMS (or AS).Described intelligent trigger is treated to existing flow process, and it mainly acts on is to carry out intelligent call control, and the function of intelligent call control comprises carries out the intelligence number of changing.
In the present embodiment, need be that the signatory IMS of circuit domain AS user triggers business in advance at HLR, promptly be signatory IMS trigger information, then follow-up HLR returns corresponding IMS trigger information according to the request message of MSC to circuit domain AS user again.Therefore, method according to present embodiment, when MSC supports the IMS trigger ability, can need not to adopt the mode of the SCP number of changing to realize the function that the IMS business is provided that circuit domain AS user is level and smooth, simultaneously, also save the connecting time that circuit domain AS user makes a call, thereby promoted the communication quality between the circuit domain AS user, promoted network performance.
With reference to figure 2, in the embodiment of the invention two, current scene is that circuit domain AS user makes a call as the calling subscriber, realizes that the method that the embodiment of the invention two is provided can may further comprise the steps:
