Description

A Realization Method of Temporary Number Change Notification Service

technical field

The invention relates to a number change notification technology, in particular to a method for realizing a temporary number change notification service.

Background technique

When the user's phone number changes temporarily, if you do not want to affect the normal communication connection, the currently available services mainly include call forwarding service, secretary station service and voice mail service, and the call forwarding service, secretary station service and voice mail service have The common feature is that calls need to be forwarded. The call forwarding service is to transfer the call initiated by the original communication terminal representing the called number to the communication terminal representing the new phone number; calls are forwarded to the specified system. Since call forwarding needs to occupy the channel resources between exchanges, the channel routing is often not optimal, so the cost of call forwarding is high, and the fees charged by operators are correspondingly high. The high cost is prohibitive, and they are afraid to use services related to call forwarding.

Fig. 1 is a schematic diagram of the implementation process of call forwarding service. As shown in Fig. 1, communication terminal 102, communication terminal 104 and communication terminal 106 belong to switching office 101, switching office 103 and switching office 105 respectively, so the telephone numbers represented by each communication terminal Differently, each switching office is connected through the voice channel 107. The exchange 103 to which the communication terminal 104 belongs has the function of transferring the call initiated by the communication terminal 104 to the communication terminal 106. When the communication terminal 102 initiates a call to the communication terminal 104, the exchange 103 will transfer the call from the exchange 101 to Switching office C 105 completes the call forwarding from communication terminal 104 to communication terminal 106, and the call direction is shown in 108.

Although when the telephone number that can be reached to the user changes, the use of call forwarding services, secretary station services, voice mail services and other related call transfer services can indeed ensure that the user's communication will not be affected, but due to Call forwarding leads to suboptimal call routing and roundabout routes, so the cost of call forwarding naturally increases significantly; The connection cost is relatively high, and the user needs to pay a lot of money to enjoy the related services of call transfer.

Contents of the invention

In view of this, the purpose of the present invention is to provide a method for realizing the temporary number change notification service, which can directly play the temporary number change voice notification to the call originator, so that the user can enjoy the practical and affordable temporary number change notification service.

Detailed ways

In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

Temporary number change notification service means that when a user's phone number changes within a period of time, in order not to affect the normal communication of the user, the communication network to which the called number belongs plays a temporary number change voice notification to the call originator to notify the call originator. The phone number of the called party is temporarily changed.

In the present invention, the user can sign a temporary number change notification service with the communication network to which the called number belongs. Play the voice notification of temporary number change, and then judge whether the current call needs to be connected according to the subscription information. If so, connect the current call to the temporary number; otherwise, disconnect the current call. When the user signs a temporary number change notification service with the network to which the called number belongs, he can only sign up to play the temporary number change voice notification. In this way, the user only needs to pay a small amount of temporary number change notification service usage fee to ensure that his communication will not be affected.

In addition, if the subscription information of the user in the communication network to which the called number belongs includes a call that can be continued, the current call can be directly connected to the temporary number, or the call originator can choose whether to connect the call. If the call originator chooses to continue the call, Then connect the current call to the temporary number; otherwise, disconnect the current call. Further, the communication network to which the called number belongs can judge whether the call originator belongs to the call originator list of the connected call according to the call originator list set by the user, and if the call originator belongs to the call originator of the connected call party list, the current call can be directly connected to the temporary number, or the call originator can choose whether to connect the call, if the call originator chooses to connect the call, the current call will be connected to the temporary number, otherwise, the current call will be removed; if the call initiates If the party does not belong to the call originator list of the connected call, the current call will be disconnected directly.

Fig. 2 is a schematic diagram of the realization process of the temporary number change notification service. As shown in Fig. 2, communication terminal 102, communication terminal 104 and communication terminal 106 belong to switching office 101, switching office 103 and switching office 105 respectively, so the telephones represented by each communication terminal The numbers are different, and each switching office is connected through the voice channel 107. The communication terminal of a certain user is temporarily changed from communication terminal 104 to communication terminal 106. When communication terminal 102 initiates a call to communication terminal 104 through route 201, switching office 103 plays a temporary number change voice notification to communication terminal 102 through route 201, The communication terminal 102 is notified that the user has been changed from the communication terminal 104 to the communication terminal 106, and the communication terminal 102 initiates a call to the communication terminal 106 through the router 202 after listening to the number change voice notification played by the exchange 103.

In the wireless communication network, if the user signs a temporary number change notification service with the communication network to which the called number belongs, the subscription information of the temporary number change notification service will be stored in the attribution information storage, so the attribution information storage can determine whether the called number is Signed a temporary number change notification service, and then determined the follow-up operation.

Fig. 3 is the flow chart that realizes temporary number change notification service in the present invention, as shown in Figure 3, present embodiment realizes temporary number change notification service by the interaction of Mobile Switching Center (MSC) and attribution information storage, MSC here and The attribution information memory belongs to the communication network to which the called number belongs, and the process of realizing the temporary number change notification service includes the following steps:

Steps 301 to 303: The MSC determines that the current call is a normal incoming call, and then sends identification information to the home information storage, and notifies the home information storage that the current call is a normal incoming call through the identification information. After receiving the identification information, the attribution information memory judges whether the phone number corresponding to the normal incoming call has subscribed to the temporary number change notification service, and if yes, executes step 304; otherwise, executes step 313.

Step 304: The attribution information storage device sends a broadcast instruction to the MSC, requesting the MSC to play the voice announcement of temporary number change.

If the user subscribes to the temporary number change notification service and only subscribes to the temporary number change voice notification, the broadcast instruction sent by the attribution information storage to the MSC may further carry the current call instruction to directly cancel the current call, requiring the MSC to finish playing the temporary number change The current call will be disconnected directly after the voice announcement. If the user subscribes to the temporary number change notification service, not only the temporary number change voice notification, but also the ability to continue the current call, the broadcast instruction sent by the home information storage to the MSC may further carry the current call instruction to directly continue the current call , requiring MSC to continue the current call directly after playing the voice notification of temporary number change; the call originator can also select the current call processing method, and then carry out follow-up processing on the current call according to the call processing method selected by the call originator. The call processing mode selected by the initiator describes the process of subsequent processing of the current call.

Steps 305 to 306: After receiving the broadcast instruction, the MSC plays the voice notification of the temporary number change to the call originator; after the MSC plays the voice notification of the temporary number change, it determines whether the broadcast instruction sent by the attribution information storage contains the direct disconnection of the current call , if there is, go to step 312; otherwise, go to step 307.

Steps 307 to 308: After receiving the current call processing mode selected by the call originator, the MSC sends the current call processing mode selected by the call originator to the attribution information storage, and the attribution information storage handles the call according to the received current call processing mode selected by the call originator. In this way, the current call indication is sent to the MSC. If the current call processing method selected by the call originator received by the home information storage is to continue the current call, an instruction to continue the current call is sent to the MSC; if the current call processing method selected by the call originator received by the home information storage is to remove the current call , then send an instruction to remove the current call to the MSC.

Step 310: The MSC judges whether to connect the current call according to the current call indication sent by the attribution information store, and if yes, executes step 311; otherwise, executes step 312.

Step 311: The MSC connects the current call to the temporary number, and ends the implementation process of the temporary number change notification service.

Step 312: The MSC disconnects the current call, and ends the implementation process of the temporary number change notification service.

Step 313: The MSC connects the current call to the called number.

In addition, when the user subscribes to the temporary number change notification service, in addition to the temporary number change voice notification, the user can also set the call originator list that can continue the call, that is, the call originator is in The current call can only be continued if it is in the call originator list of the connected call, or follow-up processing can be performed according to the current call processing method selected by the call originator; otherwise, the current call will be disconnected directly after the temporary number change voice notification is played. Like this, in step 304, also need to increase the attribution information memory to judge whether the call originator belongs to the call originator list of connecting call, if the call originator belongs to the call originator list of continuing call, then instruct MSC to directly connect the current call, or Follow up the current call according to the current call processing method selected by the call originator; if the call originator does not belong to the call originator list of the connected call, instruct the MSC to directly disconnect the current call.

The above-mentioned home information store includes at least a home location register (HLR) and a visitor location register (VLR) included in the MSC. The relevant information of the user is stored in the VLR. If the user signs a temporary number change notice service with the communication network to which the called number belongs, the contract information of the temporary number change notice service will be stored in the VLR. It is judged whether the telephone number corresponding to the normal incoming call has subscribed to the temporary number change notification service, and then the follow-up operation is determined.

Fig. 4 is the flow chart of an embodiment of realizing temporary number change notification service among the present invention, as shown in Fig. 4, the process of realizing temporary number change notification service comprises the following steps:

Steps 401 to 403: MSC receives an initial address message (IAI) with additional information, MSC analyzes the address information carried in the IAI message, and determines that the current call is a normal incoming call. The MSC sends a location request message (LOCREQ) to the HLR, and the LOCREQ message carries identification information to identify the current call as a normal incoming call.

Step 404: After receiving the LOCREQ message, the HLR determines that the telephone number corresponding to the normal incoming call has subscribed to the temporary number change notification service, and the subscription information is that the calling party can select the processing mode of the current call.

Step 405 Step 407: The HLR sends a Remote User Interaction Indication message (RUID) to the MSC. The RUID message carries a broadcast instruction and requires the MSC to play a voice notification of temporary number change. After the MSC receives the RUID message, it sends a full address message (ACM) to the call originator, and then the MSC plays a temporary number change voice announcement to the call originator, for example: the user you are calling is temporarily changed to 123, because the subscription information of the user is The calling party can choose the handling method of the current call. After the MSC plays the temporary number change voice announcement, it will continue to play the current call handling mode selection voice prompt to the calling party. For example: if you need to connect to the number, please press 1, otherwise, Please hang up, and the call originator selects the current call processing method according to the voice prompt to select the current call processing method.

Steps 408 to 410: the MSC sends a remote user interaction indication response message (ruid) to the HLR, and the ruid message carries the current call processing mode selected by the call initiator. After the HLR receives the ruid message, it sends a location request response message (locreq) to the MSC. The locreq message carries a current call indication. After the MSC receives the locreq message, it processes the current call according to the current call indication carried by the locreq message, and finally Sends a release guard signal (RLG) to the originator of the call.

The current call indication carried in the locreq message is determined by the current call processing method selected by the call originator carried in the ruid message. If the call originator chooses to continue the current call, the locreq message carries the current call indication. After receiving the locreq message, the MSC will continue The current call; if the call originator chooses to tear down the current call, the locreq message carries an instruction to tear down the current call, and the MSC will tear down the current call after receiving the locreq message.

If in step 404, the HLR judges that the subscription information of the phone number corresponding to the normal incoming call is to directly remove the current call after playing the temporary number change voice announcement, and does not need the call originator to select the current call processing method, then directly send to the MSC The locreq message carries the announcement instruction and the instruction to remove the current call, and the MSC directly removes the current call after playing the temporary number change notification voice. If in step 404, the HLR judges that the subscription information of the phone number corresponding to the normal incoming call is to directly continue the current call after playing the temporary number change voice notification, and does not need the call originator to select the current call processing method, then directly send to the MSC The locreq message carrying the announcement instruction and the instruction to continue the current call, the MSC will directly connect the current call to the temporary number after playing the notification voice of the temporary number change.

Fig. 5 is the flow chart of another embodiment of realizing temporary number change notification service among the present invention, as shown in Fig. 5, the process of realizing temporary number change notification service comprises the following steps:

Steps 501 to 503 are basically the same as steps 401 to 403.

Steps 504 to 505: After the HLR receives the LOCREQ message, it judges that the phone number corresponding to the normal incoming call has subscribed to the temporary number change notification service, and its subscription information is the list of call originators who have set up the connected call, and can be assigned by the The call originator in the call originator list of the continued call selects the processing mode of the current call, and then determines that the call originator belongs to the call originator list of the continued call.

Steps 506 to 511 are basically the same as steps 405 to 410.

If in step 505, HLR judges that the call originator does not belong to the call originator list of the connected call, then directly sends to MSC the locreq message that carries the broadcast instruction and the current call instruction, and the MSC plays the temporary number change notification voice and directly removes the current call. call.

In addition, after the user signs the temporary number change notification service, he can change the temporary number registered in the contract information at any time, so that the execution of the temporary number change notification service is more effective.

In a word, the above descriptions are only preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention.
