Abstract
The method includes steps: soft exchanger records user attribute in this phone office so as to mark out color ring users; after receiving a call to color ring user, soft exchanger continues the call to color ring user as called terminal; after ringing at the called terminal, soft exchanger informs application server in broadband network service; the application server controls media server to play back color ring; after ending the call, soft exchanger informs application server to stop playing back color ring. The invention takes full advantage of broadband network, soft exchanger, and media server device. The invention does not need to modify existed protocols or add new protocol, or to increase investment on color ring in broadband network by operation manager.
Description
Technical field
The present invention relates to the telephonic communication field, particularly relate to the media ring function of broadband network.
Background technology
Ring Back Tone service (personalized ring back tone service) has obtained well carrying out in China and even East Asia telecommunication market because its individualized feature significantly, obviously strengthens auditory perception.At networks such as narrowband network such as PHS (Personal Handyphone System), GSM (global system for mobile communications), CDMA (code division multiple access), landline telephones, there has been ripe business machine that Ring Back Tone service is provided at present.In broadband network (based on the network of IP-InternetProtocol), people have also proposed the demand demand of wide-band color bell (promptly to) to CRBT naturally.Some on a large scale investment construction the operator of broadband network, wish that the cost with minimum is that the wide and narrow strip network user provides Ring Back Tone service.The networking of broadband network presents variation at present, and SoftSwitch (SS) ability also has nothing in common with each other, so the media ring function of broadband network need provide in conjunction with concrete networking, SS ability.
Summary of the invention

Beneficial effect of the present invention
The first, in the method and system that the present invention proposes, the sign ID of each RE can be provided with, and ID quantity do not limit, and is therefore very flexible.
The second, when cascade RE quantity was few, two kinds of schemes were all fairly simple, have only simplex signaling, and need not be mutual; If cascade quantity is many, operational version two, whole flow process are still much simple than existing broadcasting negotiation method.
The 3rd, two kinds of schemes that the present invention proposes all are electric operations, mechanically actuated operation than toggle switch is reliable, and can improve reliability by increasing some verification means, for example: at up direction, every grade of RE also receives Index and IDn (n=0,1 ... N-1), and index obtains certain ID, and whether the ID by up direction relatively and the ID of down direction consistent judges whether available (afterbody RE is not off-hook or calls out final access failure) notifies APP for the ID of down direction.
Among the present invention, the color ring systems of being made up of APP, MS can provide Ring Back Tone service for broadband network, and method comprises the steps:
1), when the calling to the CRBT broadband user arrives, the SS switching called terminal.
2), dialed terminal bell, SS sends message according to user property or number segment to APP.
3), the business software logic on the APP is triggered, and connects to MS, and instruct MS connects caller, coloring ring back tone playing sound (media stream formats), and the CRBT sound is sent to calling terminal through IP network (or again through media gateway).After this step was finished, the CRBT sound was heard in caller.
4), called off-hook is replied or is called out and fails to connect, and the SS reporting message is to APP.
5), the APP instruct MS is disconnected to the connection of caller, finishes the coloring ring back tone playing sound.
6), if called party answer, then SS is updated to the media stream formats of caller, the caller incoming call; Fail to connect if call out, SS discharges related resource.
Among Fig. 1, being connected between APP and the SS be used to transmit Ring Back Tone service and trigger message etc., signaling protocol between the two is SIP.Being connected between APP and the MS is used to indicate coloring ring back tone playing sound message etc., and signaling protocol between the two is SIP or MGCP.
Introduce the flow process of wide-band color bell of the present invention below.
As Fig. 2, be that the CRBT sound path schematic diagram of color ring systems when being broadband network coloring ring back tone playing sound: MS plays storage CRBT sound thereon according to the indication that APP goes up service logic, the CRBT sound is transmitted through the such path of MS → IP network → caller (centre has media gateway device), this wherein, MS is between the IP network being the IP Media Stream.
As Fig. 3, signaling process when below being illustrated as the wide and narrow strip network Ring Back Tone service being provided:
By networking of the present invention, if the local subscriber on the SS has opened media ring function, corresponding record is then arranged in UAD, and when the calling that takes place the local exchange color ring user, elder generation's switching called terminal, notice APP prepares coloring ring back tone playing behind the dialed terminal bell, and behind end of calling (called off-hook or call out final access failure) notice APP.
1. the calling to the broadband called subscriber arrives broadband network, and SS continues called, when the beginning called party answer, sends INVITE to APP.
2.APP on the Ring Back Tone service logic software be triggered, respond 200 message to SS.
3.APP send MGCP signaling CRCX message to MS, instruct MS connects, APP is with 200 message in the MS response.
4.APP send MGCP signaling RQNT message to MS, instruct MS coloring ring back tone playing sound; With media stream formats coloring ring back tone playing sound, the CRBT sound is heard in caller to MS by IP network.
5. after called off-hook was replied, SS sent BYE message to APP.
6.APP send DLCX message to MS, instruct MS disconnects and connecting, MS responds 200 message to APP.
7.APP respond 200 message to SS, at this moment SS connects caller, the Media Stream between called, calling and called conversation.The Ring Back Tone service logic finishes.
In sum, by the present invention above-mentioned device and operational approach, can be implemented as broadband network Ring Back Tone service is provided.The present invention has made full use of broadband network and SS, MS equipment, does not require that broadband network revises existing protocol or increase new equipment Association of Musicians view; Do not need operator to increase investment for the broadband network CRBT.
The above is preferred embodiment of the present invention only, is not to be used for limiting practical range of the present invention; Every according to equivalence variation and modification that the present invention did, all contained by claim of the present invention.
