Abstract

The invention provides a system and method for realizing IP (Internet Protocol) voice mailbox outbound, wherein the method comprises the following steps: step A: when a calling user terminal calls the voice mailbox of a called user through BICC (Bearer Independent Call Control) signaling, the media server stores a voice message recorded by the calling user for the called user according to prompt after a media channel is successfully set up between a core network of the calling user and a media server of a voice mailbox business system; and step B: a voice mailbox business server of the voice mailbox business system pages the called user according to the BICC signaling, and when the called user answers, the media server is controlled to play the voice message for the called user. When a BICC protocol is used during calling, the method and system can be used for actively calling the subscriber and playing the recorded voice message under the condition with the voice message.

Description

A kind of system and method realizing the outgoing call of IPization voice mail
Technical field
The present invention relates to value-added telecom services field, particularly a kind of system and method realizing the outgoing call of IPization voice mail.
Background technology
It is the call control protocol irrelevant with carrying that ITU-TSG11 group works out that bearer independent call controls (Bearer Independent Call Control, BICC) agreement.The main feature of Bearer Independent Call Control Protocol is call service function (Call Service Function, and bearer control function (Bearer ControlFunction CSF), BCF) be separated, call control signalling can be carried on various network, comprise Message Transfer Part (MTP), SS7 network, atm network, IP network.Bearer Independent Call Control Protocol, by ISDN User Part (ISUP) protocol evolution, is the important support instrument of conventional telecommunication network to integrated multi-service e-learning quality.
The call service function of BICC defines following Four types: call business nodal function (CSF-N), mainly comprise in ISN with narrow band service and the CSF with layer equity; Call business signaling transfer point (CSF-T), mainly comprise for setting up, maintaining the bearer service signaling transfer point that between backbone network calling and other CSF peer layer, signalling relay is relevant in TSN, and be invoked in backbone network the Bearer Control signaling transfer point (BCF-T) transmitted needed for arrowband bearer service; Call business critical point function (CSF-G), mainly comprise for setting up, maintaining the bearer service signaling transfer point that backbone network is called out and signalling relay is relevant between its CSF peer layer in GSN, and be invoked in backbone network Bearer Control critical point function (BCF-G) of transmitting needed for arrowband bearer service; Call business coordination function (CSF-C), comprising provides call pacing and signalling relay relevant to be set up, maintained backbone network and call out relevant coordination function between CSF peer layer.
The bearer control function of BICC defines following five types: Bearer Control engagement function (BCF-J), the control of the carrying function of exchange of two associated call business functions (CSF), communication capacity are provided, and set up with release backbone network be connected needed for signalling capability; Bearer Control gateway function (BCF-G), provides the control of the carrying function of exchange of its associated call business function (CSF-G), communication capacity, and set up with release backbone network be connected needed for signalling capability; Bearer Control nodal function (BCF-N), provides the control of the carrying function of exchange of its associated call business function, communication capacity, and set up be discharged into equity (BCF-N) backbone network be connected needed for signalling capability; Bearer Control relay function (BCF-R), connects for completing edge-to-edge backbone network, provides the control the request of relaying bearer control signalling that carry function of exchange to next BCF; Bearer Control signaling transfer point (BCF-T), provides the control of the carrying function of exchange of its associated call business function (CSF-T), communication capacity, and set up with release backbone network be connected needed for signalling capability.
Present stage, domestic and overseas core net is carrying out the IPization transformation taken turns based on Bearer Independent Call Control Protocol, therefore, need to find a kind of method, can realize voice mail IPization transformation, can call out use Bearer Independent Call Control Protocol time, when there being tone information, can active call contracted user, play the tone information recorded.
