Description

Caller Information Service Method in Mobile Switching Network

The present invention relates to a caller information service method in a mobile telephone switching network, and more particularly, to a caller information service so that a caller can make a call by checking caller information on a call received by a subscriber of a wireless terminal.

In general, an additional service providing various services in addition to the basic call is provided to subscribers in a mobile wireless telephone network. CNIP (Caller ID) is a service that displays the calling party number unconditionally on the incoming wireless terminal. This service unconditionally marks the calling party on the called terminal, so the calling subscriber may want to control it.

An object of the present invention is to provide a caller information service method for displaying a desired number on a called terminal by a calling subscriber in a mobile telephone switching network.

The present invention for achieving the above object is characterized in that when the incoming call to the mobile phone, the calling party requests the calling party number to display only the number pressed by the calling subscriber.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals have the same reference numerals as much as possible even if displayed on different drawings. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a block diagram of a digital mobile network according to an embodiment of the present invention, and shows an example of a commercial code division multi-access (CDMA) digital mobile network. The mobile network of FIG. 1 includes a switching center including a mobile switching center (MSC) 100 as a switch, a home location register (HLR) 106 as a location register, and a plurality of base station controllers (BSCs) 108 as base station controllers. And a base transceiver station (BTS) 110, which is a base station connected to each BSC 108, and is wirelessly connected with a plurality of mobile telephones 112, a public switched telephone network (PSTN), which is a general public telephone network. And a public land mobile network (PLMN) 102. The BSC 108 performs radio link and wired link control, hand-off functions. The BTS 110 configures a wireless communication path together with the mobile phone 112 and manages radio resources. HLR 106 performs a subscriber location registration function. The VMS device 114 connected to the MSC 100 provides the VMS as described above through the MSC 100.

3 is a service processing flowchart when no caller information is provided according to an embodiment of the present invention.

1 to 3 will be described in detail the operation of the preferred embodiment of the present invention.

In the wireless telephone exchange network as shown in FIG. Proceed. Internally within the exchange, the information contained in the parameters of the operation can be used to distinguish between successes and failures and what additional services will be provided.

Referring to FIG. 2, an operation of displaying caller information (Caller ID) on the receiving subscriber's terminal at the time of providing the caller information will be described. In step 11, the BTS 110 and the BSC 108 from the mobile phone 112 are described. If there is a call originating through the originating MSC 100 in step 12 requests the location registration information to the HLR (106). Then, in step 13, the HLR 106 recognizes that caller ID is activated from the subscriber's service profile and sends a calling request signal to the calling MSC 100 to obtain a subscriber number from the subscriber. Then, in step 14, the calling party MSC 100 transmits the calling number request guide message to the mobile phone 112. At this time, in step 15, the digit number is input from the mobile phone 112 and transmitted to the calling MSC 100. Thereafter, in step 16, the source MSC 100 transmits a response signal to the source request signal to the HLR 106 and restarts the timer. In step 17, the HLR 106 sends the routing signal to the destination MSC 100 by including the received subscriber number in the parameter to obtain routing information. Then, in step 18, the destination MSC 100 allocates a number for informing the temporary station information to the HLR 106 and sends a response signal to the routing request to the HLR 106. Then, in step 19, the HLR 106 transmits a response signal for the location information request to the calling MSC 100 including various parameters. At this time, in step 20, the calling MSC 100 provides normal information to the mobile phone 112 and establishes a call with the called MSC 100. Then, in step 21, the called party MSC 100 sends a ring signal to the called party including the caller information. The caller ID is then displayed on the mobile subscriber's mobile phone. The called party then checks the caller information displayed on the mobile phone and decides whether to answer the call. In step 22, the called party connects the call between the caller and the called party.

In addition, if the calling subscriber does not provide caller information, the service operation will be described with reference to the flowchart of FIG. 4. In step 31, if there is a call originating from the mobile phone 112 through the BTS 110 and the BSC 108, step 32. The originating MSC 100 requests the location registration information from the HLR 106. Then, in step 33, the HLR 106 recognizes that caller ID is activated from the subscriber's service profile and sends the calling request signal to the calling MSC 100 to obtain the subscriber number from the subscriber. Then, in step 34, the calling party MSC 100 stops the timer being performed, sends the calling number request message to the mobile phone 112, and waits for the calling party number to be received from the mobile phone 112. At this time, if the digit for the calling party number is not received from the mobile phone 112 before the expiration of the set timer in step 35, the calling MSC 100 does not include the digit to the HLR 106 in step 35 and does not include the digit for the calling request. Send a response signal and restart the timer. Then, in step 36, the HLR 106 transmits a response signal for the location information request to the calling MSC 100 including the parameter corresponding to the failure because the calling subscriber ID was not received. Then, in steps 37 and 38, the calling MSC 100 provides the appropriate announcement to the calling subscriber and releases the call.

As described above, according to the present invention, when the calling subscriber calls the called subscriber in the mobile telephone exchange network, the caller randomly provides the caller ID when the call is made so that the calling subscriber can be displayed on the called subscriber's phone, and whether the phone number is delivered. This allows the caller to make a decision so that the mobile phone can be used efficiently.
