Abstract
The invention relates to a method for call parking of a concentrated exchange service in an IMS (internet protocol multimedia subsystem) domain, a server and a system. The method comprises the steps of: receiving by an exchange service server a first resident code transmitted by the first user when a first user talks with a second user; keeping conversation with the second user by the exchange service server; receiving by the exchange service server a second resident code for continuing the conversation transmitted by a third user; if the second resident code is consistent with the first resident code, connecting the conversation of the second user and the third user, dialing the resident code by the user, transferring the conversation to the exchange service server to carry out call parking, setting the conversation in a connected state by the exchange service server, and taking back the conversation by dialing the resident code from any telephone by the user after a moment so as to achieve seamless transition of the conversation. The conversation in a cluster can be parked, and the conversation can be answered at other places, so that the user experience is enhanced.
Description
Technical field
The present invention relates to communication technical field, refer in particular to IMS territory centrex service and call out resident method, server and system.
Background technology
IMS (IP Multimedia Subsystem; IP multimedia subsystem, IMS) is one and is based upon SIP (Session Initiation Protocol; Conversation initialized protocol) on the basis; Having merged data, voice and mobile network's system, is the real time business on present UMTS (Universal Mobile Telecommunications System, the UMTS) packet-switched domain; It with IP flexibly professional ability be planted among the GSM, greatly enriched the mobile service generative capacity.IMS generally is made up of several parts such as session management and route class, database, service, support entity and chargings.At present, IMS is considered to the core technology of next generation network.
CENTREX (CENTRalized Exchange; Virtual Private Branch Exchange PBX) business is a kind of centrex service; Be a kind of function that digital SPC exchange has, be meant that user side do not adorn any Private Branch Exchange PBX, and directly all telephone services be provided to certain enterprise by digital SPC exchange.It is widely used in the IMS territory that is now just developing rapidly, promptly merges the CENTREX business.In fact each CENTREX user is exactly a call gate; Its user type can be divided in the cluster with cluster outside; The user of authority only allows to dial intercommunication phone (as: behind the telephone number four) in the open cluster, the outer authority of open cluster can dial outside line, need add 0 or 9 before dialling outside line.Conversation is not collected the charges in the crowd, and the charge of dialing the outer phone of cluster outside the crowd is identical in plain old telephone.Except basic conversation, CENTREX also has a plurality of new business functions, such as call transfer, console, Three-Way Calling etc.
In the above-mentioned prior art, as: when the extension set in the library receives calls, because other things are arranged; Need to go to handle affairs to the laboratory; Need the conversation in this library is kept, this conversation is listened in the relaying continued access in the laboratory then, can not realize this function in the prior art.
Summary of the invention
Main purpose of the present invention provides a kind of IMS territory centrex service and calls out resident method, reciprocal exchange of business server and system; Can carry out the conversation in the cluster resident; Can continue to answer this conversation then in other places, realize continuing the seamless connection of conversation.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of IMS territory centrex service is called out resident method, and it comprises:
When first user and second user conversed, reciprocal exchange of business server received first park code that first user sends over, and reciprocal exchange of business server keeps the conversation with second user;
That reciprocal exchange of business server receives is that the 3rd user sends over, second park code of the said conversation that is used to continue, if said second park code is consistent with said first park code, then connects second user and the 3rd user's conversation.
Preferably, the park operation that makes a call is dialled in, is used to said first park code by first user.
Preferably, said maintenance conversation specifically comprises:
Confirm that according to said calling park operation first user has opened resident functions, accept said first Client-initiated and call out park operation.
Preferably, carry out and accept Client-initiated calling park operation, afterwards, also comprise:
Notify said first user to prepare second user is called out park operation;
According to first user affirmation of said notice, the media server that reinforms said second user side are play to said second user and to be holded music.
Preferably, said connection conversation specifically comprises:
Send the message of preparing to connect said conversation to second user;
Receive the affirmation of said second user to said message, and according to said affirmation with said talkthrough between said the 3rd user and said second user, and notify said second user's media server to stop to play saidly to hold music.
The present invention also provides a kind of reciprocal exchange of business server, and it comprises:

S319, reciprocal exchange of business server send Notify message (S312 is corresponding with step), inform that UE-A calls out resident completing successfully to UE-B.
S320, UE-A pass through the Notify message of the reciprocal exchange of business server among the 200OK message response step S319.
S321, UE-A initiatively send out BYE (end) message, discharge conversation.
S322, reciprocal exchange of business server send 200OK message this BYE message are responded.
User A uses new terminal equipment UE-C in S323, the crowd, dials user B in " cornet in park code+user B crowd " mode talk group, and sends invite message (medium of the SDP band UE-C of this invite message).
S324, reciprocal exchange of business server are initiated reinvite message (medium of the SDP band UE-C of this reinvite message) to UE-B, and the media server and the UE-B of reciprocal exchange of business server controls UE-B side carry out media negotiation.
The media server of S325, UE-B side is through the reinvite message among this step of 200OK message response S324 (the back medium that the SDP band UE-B of this reinvite message consults).
S326, reciprocal exchange of business server send the invite message among the 200OK message response step S323, and the SDP after the media server negotiation of UE-B side is passed through UE-C.
S327, UE-C send ACK (replying) message the 200OK message of step S326 are confirmed.
S328, reciprocal exchange of business server send the 200OK message authentication of ACK message to step S325, and UE-B and UE-C converse.
S329, UE-B send out BYE message, and the media server of notice UE-B side stops to put the music on.
The BYE message of the media server 200OK response UE-B of S330, UE-B side, the end of putting the music on.
More than be merely preferred embodiment of the present invention,, all any modifications of within spirit of the present invention and principle, being done, be equal to and replace and improvement etc., all should be included within protection scope of the present invention not in order to restriction the present invention.
