Description

Recipient mode mode service method and a mobile communication terminal for the same {RECIPIENT'S SITUATION MODE SERVICE METHOD AND MOBILE COMMUNICATION TERMINAL THEREFOR}

The present invention relates to a mobile communication system, and more particularly, to a receiver context mode service method of a mobile communication terminal in a mobile communication system.

The existing mobile communication terminal displays an incoming call to the user by generating a ring tone or vibration or operating a light emitting device when receiving a call. Therefore, when the receiver cannot answer the incoming call, for example, during a conference or performance viewing, the ring tone is blocked by changing the ring mode to the vibrate mode or turning off the mobile communication terminal. The caller then re-sends the call several times because the caller does not know what the recipient is in, but the caller cannot continue to answer the call.

As such, when the caller continues to make unnecessary connections, the caller's mobile communication terminal consumes unnecessary power and occupies an unnecessary wireless environment between the mobile communication terminal and the base station.

Therefore, if the receiver who does not answer the call conveys the current receiver's situation to the caller using his situation mode, the caller will not continue the call. Alternatively, the caller may optionally call back at intervals or may not call until the caller is contacted.

Accordingly, an object of the present invention is to provide a caller with information on whether or not the receiver can set the current situation by using a situation mode in a mobile communication terminal, and to reduce unnecessary call connections. The present invention provides a method for reducing system power consumption.

In order to achieve the above object, the present invention relates to a mobile communication terminal providing a receiver context mode service, and storing a table having data for indicating a plurality of receiver context modes and codes corresponding to the plurality of receiver context modes. A memory for temporarily storing a code for indicating a specific receiver context mode selected by the user among the plurality of receiver context modes; and when a specific receiver context mode is selected by the user, the memory corresponds to the selected receiver context mode with reference to the table. And storing a code in the memory and transmitting a code indicating a specific receiver status mode selected by the user together with its terminal location registration information upon receiving a message of a location registration request.

When the user of the mobile communication terminal cannot answer the incoming call, the receiver communication mode can be set in the mobile communication system so that the caller can select a desired service type other than a communication service requiring a voice call or a real-time response according to the receiver's situation. This makes it possible to prevent the caller from wasting time and reduce the power consumption of the terminal. In addition, in the base station and the core network, the call rejection of the called party is not known after the complete call procedure, but at an early stage, thus saving radio resources used in the subsequent call processing step, and thus the cell in the base station. ) Can increase the efficiency of radio resources and reduce the load.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

In the current mobile communication system, the connection procedure between the calling terminal and the called terminal performs the process of synchronization and channel allocation with the base station of the calling terminal when the calling terminal (Mobile Oriented) wants to access the call and requests that the call type is a voice call. When notified, the base station of the called terminal (Mobile Terminated) transmits a message and a service connection message indicating that the desired service type is a voice call to the called terminal. Accordingly, the incoming call informs the base station that the call is connected by notifying the base station of the service connection completion message.

According to the present invention, when a user of a mobile communication terminal that cannot respond to an incoming call registers his or her situation in the mobile communication system, the mobile communication system provides the sender's information to the caller so that the caller can grasp the receiver's situation. do.

Specifically, when the user of the mobile communication terminal cannot answer the incoming call, the present invention registers the receiver situation mode indicating its situation in advance to the home location register and sets the receiver situation mode when the service is activated. When an incoming call for a voice call is sent to a receiver, if the receiver status mode is set by checking the receiver status mode of the receiver at the home location register in the mobile network, the exchange does not connect the incoming call to the called terminal. Send a message or voice data to guide the situation mode to the calling terminal. Accordingly, the caller can know the situation in which the receiver cannot respond to an incoming call for a voice call or the like. In addition, the caller selects a desired service type other than a voice call according to the receiver's situation, thereby preventing the caller from wasting time and reducing power consumption of the terminal. In addition, the base station and core network not only know the recipient's call rejection after the complete call procedure but in the early stages, thus saving radio resources used in subsequent call processing steps. Cells in the cell can increase the efficiency of radio resources and reduce the load.

According to the present invention, when a user who cannot answer an incoming call such as a voice call inputs a key for setting a receiver context mode for indicating his / her situation in advance, the mobile communication terminal is configured to set the selected receiver context mode. Send the code to the base station. The base station then transmits the data transmitted from the connected mobile communication terminal to the exchange. The exchange registers data for the recipient situation mode selected from the mobile communication terminal in a home location register (hereinafter referred to as HLR). Accordingly, the HLR stores data on the receiver context mode selected by the exchange from the subscriber's mobile communication terminal.

Referring to Figure 1 described in detail the operation of the mobile communication system as follows. First, when the calling terminal 110 connects to the exchange 130 through the calling base station 120 to connect the call to the called terminal 160, the exchange 130 is connected to the home location register 140 to connect the call. Ask for incoming information. Then, the home location register 140 inquires the database of the called party and transmits the information on the receiver status mode to the exchange 130. If it is determined that the receiver status mode is set from the information from the home location register 140, the exchange 130 does not form a channel for call setup as the destination terminal 160 through the destination base station 150, and the corresponding receiver is the originating terminal. Send data according to the situation mode, for example, an SMS message or a voice guidance message. Text, ringtone, music, picture, video, picture, etc. may be used to inform the receiver status mode.

Here, the plurality of recipient situation modes include training, meeting, class, driving, bathing, using the toilet, eating, watching a performance, exercising, sleeping, using the library, and the like. By setting the receiver context mode in the mobile communication system 180, the user can inform the caller of the situation and inform the caller that he or she cannot respond to an incoming call. Then, the exchange 130 transmits the information according to the receiver context mode setting for the corresponding subscriber received from the mobile communication terminal 160 to the HLR 140 in step 212. HLR 140 sets the selected recipient context mode for the subscriber at step 214 and transmits the result to destination terminal 160 via exchange 130 at step 216. After that, the called terminal 160 displays a message indicating that the receiver status mode is set in step 218 and releases the call.

1 and 3, when the mobile communication terminal 160 receives a key for releasing a receiver context mode set by the user in step 220, the mobile communication terminal 160 transmits data including a code for this to the exchange 130. The user can receive and respond to an incoming call from the caller by releasing the receiver context mode set in the mobile communication system 180. Then, the exchange 130 transmits the information according to the release of the receiver status mode for the corresponding subscriber received from the mobile communication terminal 160 to the home location register 140 (hereinafter referred to as HLR) in step 222. HLR 140 releases the recipient context mode for the subscriber at step 224 and transmits the result to destination terminal 160 via exchange 130 at step 226. After that, the called terminal 160 displays a message indicating that the receiver status mode is released in step 228 and releases the call.

4 is a diagram illustrating a procedure for processing outgoing and incoming calls between a mobile communication terminal and a base station according to the present invention.

In the present invention, when the base station sends a message of the terminal location registration request in the idle state, the base station transmits the context mode setting of the called terminal together with the terminal location registration information and uploads the contents back to the core network (C / N). In the C / N memory or the HLR), the caller terminal informs the receiver status mode information when the calling terminal requests a call connection. Then, the core network stores the receiver status mode information in the internal memory (HLR, etc.), and when the call connection request of the calling terminal comes in, it stores the data table stored in the internal memory (HLR, etc.) and the status mode information registered by the called terminal. It can be compared and sent to the calling terminal by referring to the value, or it can be downloaded using an additional service of the value matching the situation mode table. At this time, the corner network should check in the initial stage of call connection of the calling terminal whether it is a communication service requiring voice call or real time response. It will be described below with reference to the drawings.

1 and 4, when the called terminal 160 is powered on in step 512, the called terminal 160 proceeds to step 514 to perform a cell search and enters an idle mode. In the mobile communication terminal, the idle state refers to a state in which incoming and outgoing calls are synchronized with the base station. Thereafter, when the user of the called terminal 160 sets the receiver context mode in step 516, the called terminal 160 transmits information on whether to set the receiver context mode when transmitting a message for registering his location in step 518. To be sent). The exchange 130 then stores the position information as well as the information about the receiver context mode in the HLR 140 in step 520. That is, the exchange 130 may store the receiver context mode information when updating the location information of the terminal.

Thereafter, when the calling terminal 110 requests the MO Call connection as shown in step 530, the calling terminal 110 accesses the RRC (Radio Resource Control) with the calling base station 120 in step 532 and exchanges with the called terminal 160 through the exchange 130 in step 534. Send a call for a communication service requiring a voice call or a real time response (CM Service Request). Then, the exchange 130 reads location information about the called terminal 160 from the HLR 140 and determines whether the receiver status mode is set. In this case, when the receiver context mode of the called terminal 160 is set, the exchange 130 does not form a channel for call connection to the called terminal, and sets the type and type of the receiver context mode to the calling terminal 110 in step 538. Send a message indicating Accordingly, the originating terminal 110 receives the receiver context mode of the called terminal in step 538. In operation 540, the calling terminal may check the type of the receiver status mode. In this case, the exchange 130 may request to input the voice message and the telephone number to be contacted to the calling terminal 110 in step 542. Accordingly, when the originating terminal 110 inputs the corresponding data to the exchange 130 in step 544, the exchange 130 releases the RRC with the originating terminal 110 in step 546. The originating terminal 110 transmits an RRC release complete message to the exchange 130 in response to the RRC release message in step 548.

The MSC-S-O / VLR 650 then transmits routing information for the originating terminal 660 via the Management Application Protocol (MAP) to the HLR 640 in step 605. The HLR 640 then retrieves the location information of the called terminal and checks whether the receiver status mode is set. If the receiver context mode is set, the HLR 640 does not form a channel for call connection to the called terminal, and in step 606, the RNC-O 660 notifies the RNC-O 660 of the setting and type of the receiver context mode. send. The HLR 640 then sends a roaming number to the MSC-S-T / VLR 620 in step 607 and the MSC-S-T / VLR 620 then sends an arc for the roaming number in step 608. Accordingly, in step 609, the HLR 640 transmits routing information to the MSC-S-O / VLR 650 to release the call setup.
