Problems solved by technology

[0006] If the user sets the type of call forwarding service, when the user is called and needs to be forwarded, all calling parties will be forwarded to a preset forwarding number set by the called party. The calling number of the caller is forwarded to the special service on the corresponding number

no. 1 example

[0059] In this embodiment, the GSM network and the CDMA network are taken as examples, and the user classified forwarding function and the standard unconditional forwarding are activated simultaneously.

[0060] As shown in FIG. 2 , FIG. 2 is a flow chart of the system process of forwarding when both the user standard unconditional forwarding and classified forwarding functions are activated in the communication network of the present invention. The diagram includes the following steps:

[0061] Step 201, the originating mobile switching center MSC sends a location information application to the HLR related to the mobile station MS;

[0062] In this step, for the CDMA network, the application message will carry the calling number; for the GSM network, the application information needs to be extended through the message extension parameter MAP-SEND-ROUTING-INFORMATION-REQ to carry the calling number.

[0063] Step 202, the HLR judges that the user has activated unconditional cal...

[0068] In this embodiment, a CDMA network is taken as an example, and the user's standard call forwarding on no answer and classification forwarding functions are activated at the same time.

[0069] As shown in FIG. 3 , FIG. 3 is a flow chart of the system process of forwarding when both the standard call forwarding on no answer and classified forwarding functions are activated in the CDMA network of the present invention.

[0070] In Figure 3, the following steps are included:

[0071] The originating MSC establishes a call relationship with the serving MSC by interacting with the HLR, VLR and serving MSC, specifically including:

[0072] Step 301, the originating MSC receives the directory number of the originating call and the MS;

[0073] Step 302, the originating MSC sends a location request message LOCREQ to the HLR related to the MS to obtain the called user information;

[0074] Step 303, if the called party number is assigned to a legitimate user, the HLR sends a r...

[0090] In this embodiment, the GSM network is taken as an example, and the standard forwarding on no answer and forwarding on classification functions are activated simultaneously. As shown in FIG. 4, FIG. 4 is a flow chart of the system process of forwarding when both the standard call forwarding on no answer function and the classification forwarding function are activated in the GSM network of the present invention.

[0091] In Figure 4, the following steps are included:

[0092] Step 401, when the user location is updated, if the HLR judges that the user classification forwarding function is activated, the HLR transmits the user classification forwarding information to the VLR through the extended parameters of the MAP_INSERT_SUBSCRIBER_DATA message.

Abstract

The present provides a method of realizing the classified call forwarding, which is used in the mobile communication field, comprising the steps as follows: step A, establishing and storing the correlation between the member number and the forwarding number; step B, when the classified call forwarding function of the called user and the standard call forwarding function are activated, according to the correlation between the member number and the forwarding number, obtaining the forwarding number corresponding with the call number; step C, according to the obtained forwarding number, the system conducts the call forwarding. The present invention also provides an HLR which realizes classified call forwarding and comprises a storing module for storing the correlation between the member number and the forwarding number; and a mobile exchange center for obtaining the forwarding number corresponding with the call number and conducting the call forwarding according to the stored correlation between the member number and the forwarding number. Based on classifying the calling users, the present invention realizes the service of forwarding the different call numbers to corresponding numbers, satisfying the user requirements.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and a home location register for classifying and forwarding potential caller groups of users. Background technique [0002] Currently in mobile communication systems, the call forwarding service is a common service. Call forwarding services usually include: [0003] (1) unconditional call forwarding, all the numbers of calling user terminals are forwarded to another preset number; [0004] (2) Call forwarding on no answer. When the user terminal is turned on, the incoming call is connected but no one answers it, and the incoming call will be automatically forwarded to another preset number; [0005] (3) Call forwarding when busy, when the user terminal is talking, other incoming calls will be automatically forwarded to another preset number. [0006] If the user sets the type of call forwarding service, when the user is called and needs to be forwarded, all callers...
