Abstract

PURPOSE: A caller CNHP(Calling Number History Presentation) service system and a method in a mobile communication network are provided to selectively supply call fail details and calling number information to a receiving terminal even though the receiving terminal is not registered in a CNHP service, thereby providing various CNHP services. CONSTITUTION: When a receiving request is generated to a receiving terminal(S200), an MSC confirms a position and a state of the receiving terminal(S204), and sets a speech path with a calling terminal(S205). If the receiving terminal cannot receive a call, the MSC delivers an announcement showing that a call connection fails(S206). The MSC checks whether the calling terminal is registered in a CNHP service(S208). If so, the MSC stores call fail details and calling number information(S210). If current position information and a power-on state of the receiving terminal are received(S212), the MSC reads the call fail details and the calling number information(S214), and transmits the read information as an SMS message to the receiving terminal(S216).

Description

A CNHP SERVICE SYSTEM FOR CALLER IN MOBILE COMMUNICATION NETWORK}

The present invention relates to a Calling Number History Presentation (CNHP) service in a mobile communication network. Particularly, even when a called terminal is not subscribed to a CNHP service, a call from a calling terminal to a called terminal may be selectively selected according to the calling terminal subscriber's will. The present invention relates to a sender CNHP service system and method for providing failure details and call number information.

In general, the CNHP service in a mobile communication terminal refers to a service from an external party that has failed to receive a call during an incapacity state such as power off of the user terminal, detachment of a call right, or battery discharge when the user terminal subscribed to the CNHP service returns to a callable state. It is a service that provides incoming call details and outgoing call information for outgoing calls, and extends the scope of Calling Number Identification Presentation (CNIP) that displays missed incoming call details and outgoing calls. Due to its convenience, it is one of the mobile communication terminal additional services that are widely used together with the caller information display service.

However, the conventional caller information display service and the CNHP service provide only the terminal which is already subscribed to the above service and the information on the outgoing call in the missed or unavailable state of the terminal, and thus the caller information display service or CNHP service. There was a problem in that no information on the outgoing call from the outside failed to be provided to the mobile communication terminal not subscribed to the service.

Therefore, an object of the present invention is to provide a call failure history and call number information from the calling terminal to the called terminal selectively according to the will of the calling terminal subscriber even when the called terminal is not subscribed to the CNHP service. The present invention provides a CNHP service system and method.

The present invention for achieving the above object in the caller CNHP service system using a mobile communication network, outgoing call from the terminal subscribed to the caller CNHP service to enable the display of the calling party information to the destination terminal not subscribed to the CNHP service An outgoing call storage server for storing outgoing call information and incoming call failure information of a corresponding caller for an incoming call that failed; An HLR that recognizes a call state change of the called terminal that has not been received and provides a call state and location information of the called terminal to a mobile switchboard; An SMSC for generating an unsuccessful call detail and outgoing call information provided from the calling storage server as an SMS message and transmitting the received failing call message to the corresponding called terminal that failed to receive the call; When the incoming call details and calling number information of outgoing calls from the terminal subscribed to the CNHP service are stored in the calling server storage server, and then it is confirmed from the HLR that the called terminal can be called normally. Implementing a caller CNHP service system comprising a; mobile switch for providing a call history and call number information of the called terminal stored in the call storage server to the terminal as an SMS message through the SMSC, (a) Checking a state of the called party's called terminal upon receiving an incoming call from a mobile communication terminal belonging to the mobile communication network; (b) checking whether the calling terminal is a terminal subscribed to the calling party CNHP display service which enables the calling terminal to display its calling party information on the called terminal when the connection with the called terminal fails; (c) storing the failed call details and the calling number information for the called terminal when the calling terminal is registered in the calling CNHP service; and (d) transmitting the stored outgoing call connection failure call details and calling number information to the corresponding called terminal when the callable state of the called terminal is changed.

2 is a flow chart of a caller CNHP service operation according to an embodiment of the present invention.

Hereinafter, with reference to the accompanying drawings will be described in detail the operation of the preferred embodiment according to the present invention.

1 illustrates a network configuration of a sender CNHP service system in a mobile communication network according to an embodiment of the present invention. Referring to Figure 1 below,

The mobile station (MS) 100, 102 is a user interface device that moves beyond a location registration boundary in an idle state or registers its location with the MSC 108 when a preset location registration time elapses. By transmitting the information, the location registration information of the user is updated and stored in the home location register (HLR) 116 linked with the MSC 108 through the No. 7 signal network 114.

Base Transceiver Station (BTS) 104,120 is a device configured as a wireless transceiver, and transmits / receives voice calls and SMS messages through a wireless link with the mobile communication terminals 100,102. The base station controllers (106, 118) manage a plurality of BTSs and are in charge of radio channel setup, frequency hopping, and handover processing.

The Mobile Switching Center (MSC) 108 is responsible for mobility management, location registration / management, authentication, handover, roaming, and the like of the mobile communication terminals 100 and 102. In addition, when an incoming request from the mobile communication terminal (100, 102) is received through the base station (BTS) 104, 120, an outgoing signal is transmitted to the called party of the incoming request, and there is a response from the other party's terminal to the incoming signal. In this case, a channel is allocated to form a communication path between the mobile communication terminals 100 and 102. In addition, according to an embodiment of the present invention, the call history and call number information is sent to the calling party storage server 112 for the outgoing call that failed due to the incapable state of the called terminal among outgoing calls from the terminal subscribed to the caller CNHP service. And, if the power-on state and location information of the called terminal from the HLR 116 is notified from the SMSC to receive the failed call history and call number information of the called terminal stored in the call storage server 112 (Short Message Service Center) (110) is provided to the destination terminal as an SMS message.

Outgoing call storage server 112 is a call failure history and outgoing call for the incoming call out of the outgoing call from the terminal subscribed to the caller CNHP service to enable the display of the calling party information to the terminal not subscribed to the CNHP service Save the information.

2 is a flowchart illustrating a one-way call information display operation control flow using a mobile communication network according to an exemplary embodiment of the present invention. Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

First, when there is a request for incoming call from any mobile communication terminal in the mobile communication network to the other party's destination terminal, the MSC 108 proceeds to step S202 in response to step S200, using the HLR 116 and the VLR. After checking the location and status of the called terminal, if the status of the called terminal is available for a call, the process proceeds from step S204 to step S205 to establish a call path with the calling terminal as in the prior art. .

However, in contrast, when the called terminal user is watching a movie, the terminal is turned off to participate in a meeting, or the called terminal receives a call from the calling terminal subscriber, such as the battery of the terminal is discharged or the call is released. If it is not received, the MSC 108 proceeds to step S206 in response to this in step S204 and informs the caller that the call connection failed due to the inability of the call terminal to the calling terminal. It transmits so that the calling terminal subscriber can recognize the connection failure of outgoing call.

In step S208, the MSC 108 checks whether the calling terminal is a terminal subscribed to the calling CNHP service, which enables the calling terminal to display the calling party information on the called terminal not subscribed to the CNHP service.

At this time, if the calling terminal is a terminal subscribed to the caller CNHP service, the MSC 108 proceeds to step S210 in response to the calling call storage server 112 and the call failure information and the calling number information. Save it.

On the other hand, if the incoming call fails due to the user's circumstances such as power off, battery discharge, or out of the right of the terminal according to the user's situation, when the called terminal becomes available again, such as power on, it is recognized by the HLR 116 and the HLR ( From 116, the MSC 108 is provided with call availability status information and location information such as power on of the called terminal.

Then, when the MSC 108 receives the power-on state and the current location information of the called terminal provided from the HLR 116, the MSC 108 proceeds to step S214 in response to this in step S212. After reading the failed call history and call number information for the called terminal from 112, and transmitting the call failure history and call number information to the called terminal through SMSC 110 in step S216. Done.

Accordingly, even if the called terminal subscriber is not subscribed to the calling party information display service, the call terminal subscriber receives the call failure history and the calling number information from the calling terminal according to the selection of the calling terminal subscriber and receives the call from the outside received when the terminal is powered off. You can check the incoming call history.

Meanwhile, in the above description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the invention should be determined by the claims rather than by the described embodiments.

As described above, in the CNHP service in the mobile communication network, even when the called terminal is not subscribed to the CNHP service indicating failed caller information when the call is unavailable, the present invention is optional according to the intention of the calling terminal subscriber. By implementing the caller CNHP service to provide the call failure history and call number information from the calling terminal to the called terminal, it expands the scope of the conventional CNHP service to provide a more diversified call information display service to the terminal subscribers It also has the advantage that it can further activate the phone call by inducing motivation for additional phone calls to the called terminal that is not subscribed to the caller CNHP service that is notified of the caller information and call failure history. have.
