Description

  Apparatus and method Calling information of receiving miss call offering service offering for GSM / UMTS}

       The present invention relates to a service for providing outgoing information for an incoming call that is provided by a mobile communication system. In particular, when a called terminal does not receive a call in a global system for mobile communication (GSM) or universal mobile telecommunication system (UMTS) network The present invention relates to an apparatus and a method for providing an outgoing call information service for an incoming call in GSM and UMTS for providing an outgoing call information service for an incoming call that provides a short message.

       The voice call between the radio terminals is a voice call originated by the originating radio terminal in a mobile communication network including an exchanger of the calling party and the called party, an HLR having the location information of the radio terminal, and a short message service center for short message transmission service. Inquiring the destination call routing information from the originating exchange to the home location register, routing the incoming call routing information to the destination exchange through the received call routing information, and connecting the voice call received at the destination exchange to the destination wireless terminal for voice call. Becomes possible.

       In addition, the outgoing voice call is in a state such as power off of the called party's wireless terminal, out of service area, busy, missed, call forwarding, call rejection, and voicemail connection. If there are a number of prior art for the method of providing the caller information.

       First there is the Voice Mail Service (VMS) or Response Calling Service (RCS).

       VMS is a method in which the caller selects the voicemail menu or automatically leaves the voicemail mode and leaves his voice and notes his / her phone number or other forwarding when the called party does not answer the call. If not, the caller sends a caller's telephone number to the receiver by clicking a button of a key input unit of the caller's mobile phone.

       However, this method is inconvenient that the caller must perform an act of leaving his / her voice or clicking a button, and thus, there is a problem in that the caller often hangs up the phone immediately without using such a service when the caller does not answer the call.

       In addition, there is a calling number display service, a Calling Number Identification Presentation (CNIP) service, or a Calling Line Identification Presentation (CLIP) service. When a caller calls a recipient by using his / her landline or mobile phone, the caller's call request signal is included in the caller. It contains various information such as ID, receiver ID, terminal ID, caller location information, other text message display information, text message content, and additional service information. And, the base station can control the caller's terminal through the control station, the base station, the CNIP service is to send the caller ID of the information directly to the destination terminal and the caller ID through the display function on the receiver terminal to the display unit of the terminal; It is a service that displays directly.

       However, such a conventional CNIP service is that the called party's wireless terminal rings at the same time as the calling party's mobile station by transmitting the caller ID to the called terminal through the base station, the base station control station, and the switching station.

       Accordingly, there is a problem in that CNIP service cannot be provided when the called party cannot receive a voice call because it does not respond in real time.

       In order to solve the above problems, the present invention is to provide an apparatus and method for providing caller information in a situation in which a voice call is not connected, in particular, outgoing calls for incoming calls according to each network configuration environment and conditions in GSM / UMTS By providing a variety of ways to provide information providing services, provides an apparatus and method for providing outgoing information service for the incoming call in GSM and UMTS to facilitate the provision of outgoing information service for the undeliverable call easily Has its purpose.

       Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

       1 is a call for the incoming call in GSM / UMTS according to an embodiment of the present invention

It is a block diagram showing the structure of an information providing service providing apparatus.

       Referring to FIG. 1, the GSM / UMTS includes a calling terminal 111, a called terminal 112, MSC / VLR (Mobile Switching Center / Visor Location Register) 1, 2 (121, 122), and a HLR (Home Location Register). 130 and a Service Center (SC) 140.

       When the calling terminal 111 transmits a call to the called terminal 112, when the called terminal 112 cannot answer, it provides a call information providing service for the incoming call.

The outgoing call information providing service for the unreachable call refers to a voice call information that has been received when the called terminal is powered off or is unable to respond to a voice call connection request due to being located in a busy or shadowed area. It indicates the service provided through the short message service when it is possible to process the message and receive the message later in the called terminal.

       MSC / VLR 1, 2 (121, 122) is a switching role that transfers the call of the calling terminal 111 to the destination terminal 112, the incoming call in the system of MSC / VLR 1, 2 (121, 122) If there is a function for providing a call information providing service for, when the called terminal 112 does not respond to the call of the call terminal 111, it is processed into a message for the call information providing service for the incoming call SC ( 140).

       The HLR 130 is a device that manages the location information of the radio terminal required to transfer the call of the calling terminal 111 from the MSC / VLR 1 (121) to the destination terminal 112 is the HLR (130).

       In addition, when the function is added to the MSC / VLR 1, 2 (121, 122) in place of the call information providing service for the incoming call in HLR (130), the HLR (130) for the incoming call The transmission information providing message is processed and transmitted to the SC 140.

       SC 140 is a center that provides a short message, and temporarily stores the outgoing information providing message for the incoming call transmitted from the MSC / VLR 1, 2 (121, 122) or the HLR 130, and then the called terminal ( In 112), when the message can be received, the transmission information providing message for the incoming call is transmitted.

       Call connection in GSM / UMTS having the configuration of Figure 1 when the call is sent from the originating terminal 111 to the terminating terminal 112, MSC / VLR 1 121 of the terminating terminal 112 from the HLR (130) The call routing information is requested, and the HLR 130 requests call routing information of the called terminal 112 to the MSC / VLR 2 122 to which the called terminal 112 belongs.

       The MSC / VLR 2 122 transmits the call routing information to the destination terminal 112 to the HLR 130 according to the call routing information request from the HLR 130. In this case, the transmitted call routing information includes power on / off information of the called terminal.

       Accordingly, the HLR 130 transmits routing information to the MSC / VLR 1 121 when the current destination terminal 112 is powered on according to the routing information received from the MSC / VLR 2 122, and transmits the routing information to the MSC / VLR 1 121. If 112 is a power off state, it notifies MSC / VLR 2 122.

       Then, the voice call may be connected to another call number, call forwarding (CF), or a voice message or a text message according to routing information or power-off information from the HLR 130 to the called terminal 112 (Voice). Mail Service (VMS).

       The method of providing outgoing information providing service for the incoming call provided by the GSM / UMTS can be divided into two methods when the MSC / VLR has the outgoing information providing service for the incoming call. In addition, the case in which the HLR has an outgoing call information providing service for an incoming call can be divided into two cases.

       First, when the MSC / VLR has a call information providing service providing function for the incoming call, when the called terminal 112 is in a power off state and the called terminal 113 is busy or in a shaded area, It will be described as a service method for the case.

       2 is a signal flowchart of a service providing method for powering off a called terminal when MSC / VLR having a catch call function is applied according to an exemplary embodiment of the present invention.

       Referring to Figure 2, MSC / VLR 1, 2 (121, 122) in the method for performing the call information providing service for the incoming call, first, the calling terminal 111 MSC / VLR 1 (121) of the calling party When requesting a call to the called terminal 112 through the MSC / VLR 1 121 transmits a routing information request message (MAP_Send Routing Info) including the call routing information of the called terminal 112 to the HLR 130 ( S201). In this case, the routing information request message includes the called party number information and the calling party number information.

       Then, the HLR 130 transmits a call routing information request message (MAP_Provide Roaming Number) to the MSC / VLR 2 122 to which the called terminal 112 belongs, using the call routing information of the radio terminal it has. (S202). In this case, the call routing information request message includes the called party number information and the calling party number information similarly to the routing information request message transmitted from the MSC / VLR 1 121 to the HLR 130.

       The MSC / VLR 2 122 determines whether the called terminal 112 can connect to the current call according to the call routing information request received from the HLR 130 in step S202, and the called terminal 112 connects to the current call. If this is possible, the MSC / VLR 2 122 transmits call routing information of the called terminal 112 to the HLR 130 so that the call can be connected.

       However, if the terminating terminal 112 is in a power-off state in which the message reception is not possible, the MSC / VLR 2 122 receives a response message (MAP_Provide Roaming Number_ACK) for the call routing information request message from the HLR 130. Informs the HLR 130 of the call routing information of the terminal 112 and the current power-off state (S203).

       The HLR 130 receives the message that the terminating terminal 112 from the MSC / VLR 2 122 is powered off and notifies the MSC / VLR 1 121 (MAP_Send Routing info_ACK) (S204).

       After the MSC / VLR 2 122 transmits the call routing information and the power-off information of the called terminal 112 to the HLR 130 (S203), the MSC / VLR 2 122 receives the information indicating that there is a call connection request to the called terminal 112. Processing to the outgoing call information providing message for the impossible call (MAP_MO Forward SM) and transmits to the message service center SC 140 (S205).

       At this time, the message processed as the outgoing call information providing message for the incoming call is the MSC / VLR 2 (122), the receiving terminal 112 is a registered subscriber of the call information providing service for the incoming call, the terminal is powered off When the call is not connected due to the message to send the SC 140 to the calling information so that the calling information can be delivered to the destination terminal 112, the number information of the designated SC 140, the calling number information, and the incoming Contains number information.

       The SC 140 transmits a response message (MAP_Mo Forward SM_ACK) to the MSC / VLR 2 122 to the outgoing information providing message for the incoming call from the MSC / VLR 2 122 (S206) and cannot receive the call. A message (MAP_SRI (Send Routing Info) for SM) requesting the location information of the called terminal 112 for transmitting the call information providing message for the call to the HLR 130 is transmitted (S207).

     Then, the HLR 130 transmits the location information of the called terminal 112 to the SC 140 (MAP_SRI for SM_ACK) (S208), and the SC 140 of the called terminal 112 received from the HLR 130. Using the location information, a transmission information providing message (MAP_MT Forward SM) for the incoming call is transmitted to the MSC / VLR 2 122 (S209).

       At this time, the outgoing call information providing message for the incoming call includes the outgoing information that was received by the called terminal 112.

       MSC / VLR 2 (122) receiving the outgoing information providing message for the incoming call is notified by sending a response message (MAP_MT Forward SM_ACK) that the message transmission is complete, when the receiving terminal 112 can receive the message ( S210).

       If the MSC / VLR 2 122 that has received the outgoing information providing message for the incoming call is in a state in which the terminating terminal 112 cannot receive the message, a Pending processing request message is put on the response message and the SC is sent. Transmit to 140.
