By saving the indication information which is obtained from the application server of simulation service of PSTN in advance in the device with the function of controlling the access network, the invention can allow the device with the function of controlling the access network to carry out relevant operation according to the indication information after detecting the hand-on information of the user, thus realizing the hotline service in the IP multimedia subsystem.
Description
Technical field
The present invention relates to a kind of implementation method of hot line service, the implementation method of hot line service belongs to communication technical field in particularly a kind of IP Multimedia System.
Background technology
IP Multimedia System (IP Multimedia Subsystem is called for short IMS) is the subsystem of the general cooperative programme of the third generation (3GPP) at the support IP multimedia service of R5 version proposition.The core characteristics of IMS are to adopt Session Initiation Protocol, and the independence that has and insert, so IMS is the essential step that strides forward to all-IP network service system.3GPP, ETSI and ITU-T are in the network integration scheme of research based on IMS under the development trend of the network integration, purpose is to make IMS become general-purpose platform based on the SIP session, thereby for the multimedia application in future provides a general business platform, and support plurality of access modes fixing and that move simultaneously, realize the fusion of fixed network and mobile network.But difference aspect professional ability of fixing and mobile IMS, the difference of architectural framework, the problems such as difference of agreement will become the key issue that can IMS realize that fixed network and mobile network are merged.
IMS provides the service needed of emulation public switch telephone network (Public SwitchedTelephone Network is called for short PSTN) to do more expansion in order to support to the fixed network user.The service feature of hot line service is among the PSTN: the user behind off-hook the stipulated time (as 5 seconds) if in do not dial, get final product the called number (also claim hot line number) of automatic connection to corresponding preset, its operation flow is as described below: behind calling subscriber's off-hook, receive dialing tone; The calling subscriber receives ring-back tone after waiting for 5 seconds, simultaneously called subscriber's phone ringing; Both sides converse behind called subscriber's off-hook.And if the instant hot line business, the called number that will set when automatic connection is to RT register traffic immediately behind user's off-hook then.From the above, the key technology point of hot line service is among the realization PSTN: switch sends calling to the predefined called number of this user after monitoring calling subscriber's off hook signal.
PSTN simulation services is the POTS terminal use at fixed network, requires the IMS network to provide the indiscriminate business with PSTN to the user.This has higher requirement to IMS, requires IMS can not only realize PSTN business such as calling transfer, Call Waiting, also will provide identical professional perception to the user.Development along with PSTN simulation services, AGCF equipment (Access Gateway Control Function, be called for short AGCF) and PSTN simulation services application server (PSTN Emulation Service ApplicationServer is called for short PES AS) become the key network element of realization PSTN simulation services gradually.But because service logic (being business processing flow) is carried out by PES AS, and the monitoring of user's off hook signal is carried out by AGCF, the separation of two functions has caused the realization of hot line service in IMS not carry out according to the implementation of hot line service among the PSTN, causes failing in the prior art realizing the hot line service among the IMS.
Summary of the invention
The objective of the invention is provides the implementation method of hot line service in a kind of IP Multimedia System at above-mentioned the deficiencies in the prior art, can realize the hot line service in the IP Multimedia System.
For achieving the above object, the invention provides the implementation method of hot line service in a kind of IP Multimedia System, comprise: the AGCF monitoring of equipment is after user's off-hook information, according to preserve in advance, from the indication information that the PSTN simulation services application server obtains, carry out the operation of this indication information indication.
In the technique scheme, AGCF equipment is by preserving the indication information that obtains from the PSTN simulation services application server in advance, and carry out corresponding operation when user's off-hook according to this indication information, thereby can overcome in the prior art service logic is preserved and is carried out by the PSTN simulation services application server, the AGCF monitoring of equipment is behind off hook signal, can not carry out the defective of corresponding operating owing to do not preserve corresponding hot line service logic, send the operation of indication information indication AGCF equipment by the PSTN simulation services application server to AGCF equipment, thereby can realize the hot line service in the IP Multimedia System.
Preferably, in technique scheme, before described AGCF monitoring of equipment arrives user's off-hook information, can comprise that also described AGCF equipment preserves the operation of described indication information in advance, specifically comprise: described PSTN simulation services application server monitor the user open hot line service and receive business datum after or after upgrading user's business datum, to described AGCF equipment dispatch order message, and in this notification message, comprise this user's of preservation hot line service configuration information in advance; After described AGCF equipment is received described notification message, described hot line service configuration information is preserved as described indication information.
At described PSTN simulation services application server before described AGCF equipment dispatch order message, can comprise that also described PSTN simulation services application server preserves the operation of described hot line service configuration information in advance, specifically comprise: described AGCF equipment is after user registration success, send subscribe message to described PSTN simulation services application server, be used to subscribe to this user's hot line service configuration information, described hot line service configuration information comprises the called number of user preset, and be used to indicate whether this user's business is the information of instant hot line business.
Further, the operation of this indication information indication of described execution can comprise: described AGCF equipment judges according to described indication information whether this user's business is the instant hot line business, be that the called number that then comprises in described indication information immediately makes a call, otherwise judge whether the user dials in the default time interval, if dialing then make a call to the number that the user dialled is not if dial then the called number that comprises in described indication information makes a call.
Pass through aforesaid operations, the PSTN simulation services application server sends the notification message that comprises the hot line service configuration information to AGCF equipment, make AGCF equipment to indicate whether information according to the called number that comprises in the described hot line service configuration information and being used to for the instant hot line business, after monitoring user's off-hook information, carry out correspondent service logic, thereby realize the hot line service among the IMS.
Preferably, in technique scheme, before described AGCF monitoring of equipment arrives user's off-hook information, can comprise that also described AGCF equipment preserves the operation of described indication information in advance, specifically comprise: described PSTN simulation services application server monitor the user open hot line service and receive business datum after or after upgrading user's business datum, to described AGCF equipment dispatch order message, and in this notification message, comprise the hot line service processing indication information of preserving in advance; After described AGCF equipment is received described notification message, described hot line service is handled indication information preserve as described indication information.
