After reading the specific embodiment of the present invention by reference to the accompanying drawings, the other features and advantages of the invention will become clearly.

Accompanying drawing explanation

In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 1 is calling FB(flow block).

Embodiment

Common call flow is as follows:

1, calling authorization: whether authentication of users has call authority

Launch after button when user inputs complete the pressing of called number, mobile phone (replacing with MS below) will carry out a series of actions.

First MS will in Random Access Channel (RACH) to BSS channel request message, to apply for a dedicated channel (SDCCH), BSC for its distribute corresponding channel success after, be the dedicated channel that it distributes by the notice of assignment messages immediately MS in access grant channel (AGCH)

MS will be transmission layer three message---CM business request information on its SDCCH distributed subsequently, CM type of service makes a call for mobile within the message, this message by BSS transparent be sent to MSC, after MSC receives CM business request information, by the access service request of this MS of process access request message informing VLR process, (meanwhile, there is Connection Service owing to having used SCCP between the bsc and the msc, connect for setting up SCCP, MSC also will return to BSC and connect acknowledge message).

After receiving service access request, first VLR will check whether this MS has authentication three ginseng group in a database, if had, authentication order will be issued directly to MSC, otherwise, ask authentication parameter to corresponding HLR/AUC, obtain three ginseng groups from HLR/AUC, and then issue authentication order to MSC.After MSC receives the authentication order of VLR transmission, authentication request is issued to MS, containing authentication parameter in this order, after MS receives authentication request by BSS, utilize the IMSI in SIM card and authentication arithmetic, draw authenticating result, send to MSC by authentication response message, MSC is by authenticating result loopback VLR, authenticating result that MS reports is checked and from the result the authentication parameter that HLR obtains by VLR, if the two is inconsistent, refuse this access request, this time call failure; If the two is consistent, authentication is passed through, after authentication is passed through, first VLR will issue encrypted command to MSC, then notify that this access request of this MS of MSC has obtained to pass through, by BSS, MSC notifies that MS service request passes, then MSC issues encrypted command to MS, this order includes encryption mode, MS receives this and to order and after completing encryption, message has been encrypted in loopback, completes the work of whole access phase to this MS.

2, server sets up calling

After access phase and authentication ciphering process, the legal identity of calling subscriber is confirmed, access network, for proceeding calling, need information specifically, according to specification, now MS is by transmission set up message, in this message, carry the information specifically such as called number and calling identification, after MSC receives this message, first inquired about the related service information of this user to VLR by S.I.F.O message, the business information that VLR has applied for MS when opening an account according to this class of service, determine this time whether calling can continue.

If can continue, by completing message related to calls to this user data of MSC loopback, after MSC receives this information, by calling continuation message, notify that MS calling is among continuation process through BSS, then, according to A interface circuit situation, send assignment request message to BSC, within the message selected certain A interface circuit, after BSC receives this instruction, to BTS, MS specific radio resource, after MS receives this instruction, take successfully loopback and be assigned message, complete to this TCH assignment stage, the Radio Resource of local exchange becomes the distribution of work all with A interface circuit.

MSC receives after assignment that MS reports completes message, carry out called number analysis, according to called number, be addressed to HLR, send routing information request message, after HLR receives this message, the VLR at called place is obtained according to called IMS I inquiry, VLR to called place asks roaming number, the VLR at called place is after being subject to request roaming number message, for the MS of correspondence distributes MSRN, then in request roaming number response message loopback to HLR, after HLR obtains this MSRN, routing iinformation response message is sent to caller place MSC, MSC obtains called MSRN from this message, interoffice junction routing is carried out according to MSRN, and send IAI message to the MSC at called place.So far caller signaling process terminates substantially.

3, paging is called

After an end office (EO) MSC receives the IAI message of its office's transmission, in order to determine whether called subscriber can accept this time calling, MSC can first by S.F.I.C message to the user profile of corresponding VLR inquiry about this called subscriber, if VLR passes through searching user's information, find that this user can accept this time calling (do not shut down and allow call accepted), paging command message can be sent to MSC, within the message, positional information (LAI) containing user, after MSC receives this information, data query, obtain the signaling point code of the BSC controlling this lane place, to the order of corresponding BSC distributing paging, BSC notifies that the BTS controlled is at paging channel (PCH) issuing page message.This channel intercepted by mobile phone always, when after the message receiving paging self, page-response message is reported in Random Access Channel (RACH), (there is Connection Service due to what used SCCP at A interface, so page response is regarded as the connection establishment request message of SCCP simultaneously, the SCCP layer correspondence of MSC should return a CONNect Acknowledgement message).

MSC is to VLR transmission processing access request message simultaneously, first VLR starts authorizing procedure, check the authentication parameter group of this user, if the authentication three ginseng group of not this user in VLR, VLR can initiate the process (detailed process can see the authentication process in the access procedure of calling subscriber) of getting authentication parameter to HLR, otherwise VLR can send directly to MSC and start authentication message, starting an authentication three ginseng group (RAND containing this user in authentication message, KC, SERS), after MSC receives this message, can continue to notify corresponding BSC, BTS issues authentication order, after MS receives authentication request, according to the KI in SIM card, calculate corresponding SERS, afterwards, SERS is reported MSC in authentication response message, MSC is recycled to VLR, after VLR receives authentication response message, check the SERS reported whether consistent with the SERS in the three ginseng groups obtained from HLR, if consistent, send access request to MSC and accept message, the this time access request of this user of notice MSC is accepted.And by completing message related to calls to the called user profile of MSC loopback; If inconsistent, this time calling will be rejected.

4, set up calling

After MSC has received message related to calls, SETUP message is sent to BSS side, foundation is called out by prompting, after MS receives this message, loopback call confirmation message, afterwards, MSC selects corresponding A interface circuit, BSC to correspondence sends assignment request message, BSC distributes corresponding Radio Resource according to resource situation, and notify MS, MS takies loopback successfully and has assigned message, called MS starts to shake bell simultaneously, shake bell message is returned to its place MSC, this MSC returns Address Complete Message to caller place MSC, caller place MSC sends called shake bell message to MS, now host subscriber can hear ring-back tone, if called subscriber determines to accept this time calling, by response button, this action is become CONNECT message by mobile phone translation, send to MSC, after MSC receives this message, send response message (ANC), after caller MSC receives this message to caller MSC, connection establishment request message is sent to caller MS, caller MS returns CONNect Acknowledgement message to caller place MSC accordingly, and this message is sent to called MS through called MS C, so, this this calling starts call, and both sides converse.

The present invention proposes a kind of user on the basis of the above and freely arranges state of cannot answering and carry out the called current state of subscriber call by the method for announcement record and when recovery can be answered state online.By increasing a kind of new User Status in hlr: cannot state be answered from arranging.WCS (wireless call server) needs to increase a set of special number analysis to trigger intelligent platform, arranges cannot answer state to guide user, and the user that records is from the message notification arranged.State cannot be answered from arranging, when WCS receives the phone of this user of calling, by the recorded announcement that this phone of connection is reserved to this user when called subscriber is provided with.Wherein, HLR is the important entity forming cdma network, and it is responsible for preserving user attaching message and current location information, thus can set up the calling to mobile phone.Attaching position register and AUC integrate by HLR, provide the several functions such as location updating, roaming management, authentication, calling; HLR also supports the supplementary service enriched, and as Call Forwarding, call barring, caller ID display and restriction, short message etc., user uses handy.MSC is mobile switching centre.VLR is VLR Visitor Location Register.

Arranging that system supports this function to need is as follows: 1, HLR needs to increase recorded announcement business.

First need amendment HLR software code, increase the code of the function supporting recorded announcement business.This code revision mainly increases the data structure of resolving recorded announcement business, make HLR system natively with order support parameter recorded announcement business, and can arrange and resolve this business.Then an operation manager needs the order using HLR system to provide to open this business for needing the user opening recorded announcement business.

2, MSC/VLR needs to support this supplementary service simultaneously, recorded announcement business.

First MSC/VLR also needs to revise software code, increases the code supporting recorded announcement business function.This code revision mainly increases the identification to this service code, resolves and disposal ability.Such as handset call ##123#, MSC/VLR analyze ##123# and just trigger intelligent platform.User is activated according to the recorded announcement of intelligent platform by intelligent platform, or this business of deexcitation.The information that MSC/VLR needs this user of notice HLR to activate recorded announcement business simultaneously issues HLR.HLR preserves user and has activated the information of this service and the MSRN comprising intelligent platform code for this user distribution.MSC also needs to increase numerical analysis and will call out the call routing of this user to intelligent platform with the MSRN comprising intelligent platform code that can send here according to HLR.

3, intelligent platform needs to support user to leave and take and record and plays to calling out other users of this user the recording that user leaves and takes.

Intelligent platform needs to configure recorded announcement and hear that the rear different numbers input of recording performs different orders according to user, and such as input 1 and activate this business, this business of input 2 cancellation, input 3, listens to the recording of having preserved, and input 4 returns Previous Menu.

Call out when arranging and activate the user of this business when there being user, the MSRN comprising intelligent platform code sent here according to HLR as MSC/VLR routes the call to intelligent platform, the recording that the called number that intelligent platform Water demand MSC/VLR sends here is left and taken to play respective user.

User uses the flow process of this business as follows with reference to figure 1:

User needs to open this business by operator.After opening, a new supplementary service can be increased in this user data that HLR deposits, recorded announcement business.

When user needs to use this business, user needs to dial a special number, such as ##123#, MSC/VLR is after the number receiving user's input, whether the information of first inquiring about this user that HLR sends here opens recorded announcement business to inquire about this user, if open this business, trigger intelligent platform.According to the number of the intelligent platform that HLR sends here, this phone can be routed to intelligent platform by MSC/VLR.

Intelligent platform can activate this business by this user of voice message, such as inputs 1 and activates this business, and this business is cancelled in input 2, and input 3, listens to the recording of having preserved, and input 4 returns Previous Menu.When user saves the recorded announcement of this user according to recorded announcement, now activate this business and complete.

When other user calls out this user (this user can be mobile phone and fixed line), the HLR of exchange opportunity inquiry belonging to called subscriber that other user makes a call, the message that this user can have been activated recorded announcement by HLR and the MSRN comprising intelligent platform code issue the switch of the user made a call.This calling of MSRN route that the exchange opportunity of the user made a call is sent according to HLR is to intelligent platform, and intelligent platform carrys out subscriber call according to the called number that switch route is come and removes to listen to the recorded announcement that called subscriber stays.

When this user can receive calls or want to cancel recorded announcement time, this user needs to dial a certain special number, such as ##124#, MSC/VLR is after the number receiving user's input, whether the information of first inquiring about this user that HLR sends here opens recorded announcement business to inquire about this user, if open this business, trigger intelligent platform.According to the number of the intelligent platform that HLR sends here, this phone can be routed to intelligent platform by MSC/VLR.

Intelligent platform by this business of this user operation of voice message, can comprise activation, deexcitation, recording etc.

Last it is noted that above embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
