In the Integrated Service Digital Network system, stored-program control exchange (PBX) has been used in the office mechanism of enterprise widely, has greatly improved the work efficiency of enterprise.When terminal called (exchange) conversation under calling terminal needs and this stored-program control exchange, calling terminal needs and terminal called connects, finish the conversation of calling terminal and terminal called, this terminal called also can select the extension set of self to finish conversation with calling terminal simultaneously.And this moment, terminal called also can select a number (number of the extension set of conversing with calling terminal) to be shown to calling terminal, rather than showed the number of this terminal called exchange, Here it is so-called IMS called number display business.In addition, when for a terminal called a plurality of number being arranged, in the process of once conversation, the current called number of terminal called also may be different with its number that is shown to calling terminal.
IMS called number display business can realize that the called number that terminal called need show passes to calling terminal by Session Initiation Protocol signaling in being with and shows based on ISDN called number display business.
The implementation of existing called number display business is as follows:
Referring to Fig. 1, it is a called number display business flow chart between existing territory.In the present embodiment, calling terminal is to be arranged in PSTN (PSTN), and terminal called is arranged in the IMS territory.This flow process specifically comprises:
Step 1-2, MGCF entity (MGCF) send to called user terminal (UE) by CSCF/application server (CSCF/AS) and invite (INVITE) message;
Step 3-6 after called UE receives INVITE, feeds back 180 message by CSCF/AS to MGCF, feeds back 200OK message afterwards;
Step 7-12, MGCF are in order to finish the called number display business, after the 200OK message of receiving from called UE, to called UE feeding back ACK message; Afterwards, wait for renewal (UPDATE) message receive from called UE after, just give PSTN network answer ANM.If this moment, called UE was called out according to this, need determining numbers displayed is to be different from the current called number of called UE, as this calling is an extension set of called UE, then called UE will show that the number of extension set is to calling UE, this UPDATE message comprises that this calling need be shown to the number of the called UE of calling UE, if perhaps this called UE has a plurality of numbers, called UE needs numbers displayed and the current called number of called UE not simultaneously, and this UPDATE message comprises that this calling need be shown to the number of the called UE of calling UE.Afterwards, MGCF is to calling UE feedback 200OK message, and this 200OK message comprises that this calling need be shown to the number of the called UE of calling UE, connects the calling and called terminal, realizes conversation, and finishes the called number display business.
As seen, in order to realize the called number display business, MGCF replys ANM could for the PSTN network after will waiting until called UE feedback UPDATE message, show that on calling UE this calls out the number that needs the called UE that shows, so not only continue slow and also flow process complicated.
Referring to Fig. 2, it is a called number display business flow chart between existing territory.In the present embodiment, the calling and called terminal is all to be arranged in the IMS territory.This flow process specifically comprises:
Step 1-3, calling UE sends INVITE by the CSCF/AS in the caller network, the CSCF/AS in the called network to called UE;
Step 4-9 after called UE receives INVITE, feeds back 180 message by the CSCF/AS in the CSCF/AS in the called network, the caller network to calling UE, feeds back 200OK message afterwards;
Step 10-12, calling UE sends ACK message to called UE, connects the calling and called terminal afterwards, realizes conversation.
Step 13-18 after calling UE is received UPDATE message from called UE, to called UE feedback 200OK message, realizes the called number display business.If this moment, called UE was called out according to this, need determining numbers displayed is to be different from the current called number of called UE, as this calling is an extension set of called UE, then called UE will show that the number of extension set is to calling UE, this UPDATE message comprises that this calling need be shown to the number of the called UE of calling UE, this 200OK message comprises that this calling need be shown to the number of the called UE of calling UE, the called number display business.
Though above-mentioned flow process can realize showing the called number business, but, owing to be after the calling and called terminal is connected, caller just receives the UPDATE message from terminal called, like this, calling terminal also might send message when receiving this message, therefore, can cause the message collision business that makes to carry out owing to the calling and called terminal sends message simultaneously.
If avoid the message collision, calling UE could be connected with called UE after will receiving UPDATE message by the time, though can avoid the message collision like this, the time delay of call through obviously extends.
Therefore, in existing flow process, if realize the called number display business, or prolong the connection time delay between the calling and called terminal, or will can't carry out because of the message collision business that makes.
