In the present invention, the user can be with the signatory interim changed number notification business of the communication network under the called number, when call initiator makes a call to this user's called number, communication network under the called number is play the verbal announcement of the number of changing temporarily according to CAMEL-Subscription-Information to call initiator, and then judge whether the needs current calling that continues according to CAMEL-Subscription-Information, if, with current call proceeding to temporary number; Otherwise, remove current calling.The user is with the signatory interim changed number notification of called number belonging network when professional, can the only signatory broadcast number of changing temporarily verbal announcement, and like this, the user only need pay the professional cost of use of a spot of interim changed number notification just can guarantee that the communication of self is unaffected.
In addition, but if comprise replay call in user's the CAMEL-Subscription-Information in the communication network under the called number, then can be directly with current call proceeding to temporary number, also can whether select replay call by call initiator, if call initiator is selected replay call, then with current call proceeding to temporary number; Otherwise, remove current calling.Further, communication network under the called number can according to the user be provided with can replay call the call initiator list, judge whether call initiator belongs to the call initiator list of this replay call, if call initiator belongs to the call initiator list of this replay call, then current calling directly can be continued to temporary number, also can whether select replay call by call initiator, if call initiator is selected replay call, then with current call proceeding to temporary number, otherwise, remove current calling; If call initiator does not belong to the call initiator list of this replay call, then directly remove current calling.
Fig. 2 is interim changed number notification business realizing process schematic diagram, as shown in Figure 2, communication terminal 102, communication terminal 104 and communication terminal 106 belong to exchange 101, exchange 103 and exchange 105 respectively, so the telephone number difference of each communication terminal representative, each exchange couples together by speech channel 107.A certain user's communications terminal changes to communication terminal 106 by communication terminal 104 temporarily, when communication terminal 102 is initiated calling to communication terminal 104 by route 201, exchange 103 is play the verbal announcement of the number of changing temporarily by route 201 to communication terminal 102, notifying communication terminal 102 these users change to communication terminal 106 by communication terminal 104, communication terminal 102 makes a call to communication terminal 106 by route 202 after hearing out the number of the changing verbal announcement of exchange 103 broadcasts.
In cordless communication network, if the signatory interim changed number notification business of the communication network under user and the called number, to store the CAMEL-Subscription-Information of interim changed number notification business in the attaching information memory, therefore, the attaching information memory can be judged called number whether contracted interim changed number notification business and then definite subsequent operation.
Fig. 3 is for realizing the flow chart of interim changed number notification business among the present invention, as shown in Figure 3, present embodiment is by the mutual realization interim changed number notification business of mobile switching centre (MSC) with the attaching information memory, MSC herein and attaching information memory all belong to the communication network under the called number, realize that the process of interim changed number notification business may further comprise the steps:
Step 301～step 303:MSC determines that current calling is normal incoming call, sends identification information to the attaching information memory then, is normal incoming call by the current calling of this identification information notice attaching information memory.The attaching information memory is received identification information, judges and the corresponding telephone number of this normal incoming call interim changed number notification business of whether contracting, if, execution in step 304; Otherwise, execution in step 313.
Step 304: the attaching information memory sends the broadcast indication to MSC, requires MSC to play the verbal announcement of the number of changing temporarily.
When if the signatory interim changed number notification of user is professional, the verbal announcement of the number of changing temporarily of only having contracted, then the attaching information memory can further carry the current calling indication of the current calling of direct dismounting in the broadcast indication that MSC sends, and directly removes current calling after requiring MSC to play the verbal announcement of the number of changing temporarily.When if the signatory interim changed number notification of user is professional, contracted outside the verbal announcement of the number of changing temporarily, the current calling that to continue of also having contracted, then the attaching information memory can further carry the current calling indication of the current calling that directly continues in the broadcast indication that MSC sends, and requires MSC to play the current calling that directly continues after the verbal announcement of the number of changing temporarily; Also can select the processing mode of current calling by call initiator, the call treatment mode of selecting according to call initiator is carried out subsequent treatment to current calling then, and the process that the call treatment mode of selecting according to call initiator is carried out subsequent treatment to current calling is described below.
Step 305～step 306:MSC plays the verbal announcement of the number of changing temporarily to call initiator after receiving the broadcast indication; After MSC plays the verbal announcement of the number of changing temporarily, judge the current calling indication that whether carries the current calling of direct dismounting in the broadcast indication that the attaching information memory sends, if having, execution in step 312; Otherwise, execution in step 307.
After step 307～step 308:MSC receives the current call treatment mode of call initiator selection, send the current call treatment mode that call initiator is selected to the attaching information memory, the current call treatment mode that the attaching information memory is selected according to the call initiator of receiving sends current calling indication to MSC.If the current call treatment mode that the call initiator that the attaching information memory is received is selected is the current calling that continues, then send the current calling indication that continues to MSC; If the current call treatment mode that the call initiator that the attaching information memory is received is selected for removing current calling, then sends to MSC and removes current calling indication.
Step 310:MSC indicates the current calling that judges whether to continue according to the current calling that the attaching information memory sends, if, execution in step 311; Otherwise, execution in step 312.
Step 311:MSC to temporary number, finishes interim changed number notification business realizing flow process with current call proceeding.
Step 312:MSC removes current calling, finishes interim changed number notification business realizing flow process.
Step 313:MSC with current call proceeding to called number.
In addition, the user is when signatory interim changed number notification is professional, contracted outside the verbal announcement of the number of changing temporarily, also contracted and to have continued under the situation of current calling, the user also can be provided with can replay call the call initiator list, be call initiator in the call initiator list of this replay call, the current calling that just can continue, or carry out subsequent treatment according to the current call treatment mode that call initiator is selected; Otherwise, play the verbal announcement of the number of changing temporarily after, the just directly current calling of dismounting.Like this, in step 304, also need increase the attaching information memory and judge whether call initiator belongs to the process of the call initiator list of replay call, if call initiator belongs to the call initiator list of replay call, the then instruct MS C current calling that directly continues, or subsequent treatment is carried out in current calling according to the current call treatment mode that call initiator is selected; If call initiator does not belong to the call initiator list of replay call, then instruct MS C directly removes current calling.
Above-described attaching information memory comprises the Visited Location Registor (VLR) that comprises among attaching position register (HLR) and the MSC at least.Storage user's relevant information among the VLR, if the signatory interim changed number notification business of the communication network under user and the called number, to store the CAMEL-Subscription-Information of interim changed number notification business among the VLR, therefore, the VLR that MSC comprises by himself just can judge fully and whether the corresponding telephone number of this normal incoming call has contracted interim changed number notification business and then definite subsequent operation.
Fig. 4 as shown in Figure 4, realizes that the process of interim changed number notification business may further comprise the steps for realizing an embodiment flow chart of interim changed number notification business among the present invention:
Step 401～step 403:MSC receives the initial address message (IAI) of band additional information, and MSC analyzes the address information of carrying in the IAI message, determines that current calling is normal incoming call.MSC sends location request message (LOCREQ) to HLR, carries identification information in this LOCREQ message, is normal incoming call in order to identify current calling.
After step 404:HLR receives LOCREQ message, judge and the normal corresponding telephone number of the incoming call interim changed number notification business of having contracted, and its CAMEL-Subscription-Information is for being selected the processing mode of current calling by call initiator.
Step 405～step 407:HLR sends the mutual Indication message of remote subscriber (RUID) to MSC, and this RUID message is carried the broadcast indication, requires MSC to play the verbal announcement of the number of changing temporarily.After MSC receives RUID message, send Address Complete Message (ACM) to call initiator, MSC plays the verbal announcement of the number of changing temporarily to call initiator then, for example: user's temporary changes that you called out are 123, because user's CAMEL-Subscription-Information is for being selected the processing mode of current calling by call initiator, then after MSC plays the verbal announcement of the number of changing temporarily, continuation is play current call treatment mode to call initiator and is selected voice suggestion, for example: need to connect this number please by 1, otherwise, please on-hook, call initiator selects voice suggestion to select current call treatment mode according to current call treatment mode.
Step 408～step 410:MSC sends remote subscriber to HLR and indicates response message (ruid) alternately, and this ruid message carries the current call treatment mode that call initiator is selected.After HLR receives ruid message, send position request response message (locreq) to MSC, this locreq message carries current calling indication, after MSC receives locreq message, according to the current calling indication that this locreq message is carried current calling is handled, sent release guard signal (RLG) to call initiator at last.
The current call treatment mode that the call initiator that the current calling indication that locreq message is carried is carried by ruid message is selected is determined, if call initiator selects to continue current calling, then locreq message carries the current calling indication that continues, after MSC received locreq message, current calling continued; If call initiator selects to remove current calling, then locreq message carries and removes current calling indication, after MSC receives locreq message, removes current calling.
If HLR judges with the CAMEL-Subscription-Information of the normal corresponding telephone number of incoming call and directly remove current calling after playing the verbal announcement of the number of changing temporarily in step 404, do not need call initiator to select current call treatment mode, then directly send the locreq message that carries the broadcast indication and remove current calling indication to MSC, MSC plays interim changed number notification voice and directly removes current calling.If in step 404 HLR judge with the CAMEL-Subscription-Information of the normal corresponding telephone number of incoming call for playing the current calling that directly continues after the verbal announcement of the number of changing temporarily, do not need call initiator to select current call treatment mode, then directly send the locreq message that carrying the broadcast indication and continuing current calling indication to MSC, MSC play interim changed number notification voice directly with current call proceeding to temporary number.
Fig. 5 as shown in Figure 5, realizes that the process of interim changed number notification business may further comprise the steps for realizing another embodiment flow chart of interim changed number notification business among the present invention:
After step 504～step 505:HLR receives LOCREQ message, judge and the normal corresponding telephone number of the incoming call interim changed number notification business of having contracted, and its CAMEL-Subscription-Information is the call initiator list that is provided with replay call, and can select the processing mode of current calling by the call initiator of the call initiator list that belongs to replay call, judge the call initiator list that call initiator belongs to replay call then.
Step 506～step 511 is basic identical with step 405～step 410.
If HLR judges the call initiator list that call initiator does not belong to replay call in step 505, then directly send the locreq message that carries the broadcast indication and remove current calling indication to MSC, MSC plays interim changed number notification voice and directly removes current calling.
In addition, after the signatory interim changed number notification business of user, can change the temporary number of registering in the CAMEL-Subscription-Information at any time, make the execution of interim changed number notification business more effective.
In a word, the above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
