Description

A method for refusing an incoming call, a mobile terminal and a method for leaving a message on a telephone call

technical field

The present invention relates to the technical field of wireless communication, in particular to a method for rejecting an incoming call and a mobile terminal for rejecting an incoming call used in the method. Based on the mobile terminal of the present invention, the present invention also provides a method for leaving a message on a telephone call .

Background technique

Ordinary telephone service, as a basic telecommunication service, is the most important service provided by the mobile communication network. Through the ordinary telephone service, mobile users can realize real-time two-way voice conversations with mobile users or fixed-line telephone users. The following describes several processes involved in a voice call:

1. Mobile origination call establishment

When a user wants to initiate a call through a user equipment (UE), the UE uses radio interface signaling to establish communication with the network, and sends a message containing the number of the called user. The core network (core network, CN for short) will establish a communication channel to the UE, and use the address of the called party to create an IAM message and send it to the called party. As shown in the signaling diagram in Figure 1, the specific process includes:

1) The UE sends a channel request CHANNEL REQUEST message to the Radio Network Subsystem (RNS for short) on the Random Access Channel (RACH). See signaling a in Figure 1;

2) The RNS responds with an immediate assignment IMMEDIATE ASSIGNMENT message, so that the UE can use the designated signaling channel. See signaling b in Figure 1;

3) The UE sends an initial service request message CM SERVICE REQUEST to the CN. See Figure 1 signaling c;

4) The network will initiate the authentication and encryption process. Refer to signaling d and e in Fig. 1;

5) After sending the security mode complete (SECURITY MODE COMPLETE) message, the UE initiates the call establishment process by sending the setup (SETUP) message to the network. Refer to Fig. 1 signaling d, e, f, g, h;

6) The network will respond with a CALL PROCEEDING message. Refer to Fig. 1 signaling i;

7) CN will send a radio channel assignment request (RAB ASSIGNMENT REQ) message to RNS to request radio channel assignment, and RNS will order UE to adjust to a designated communication channel by sending an assignment message to UE, and UE will adjust to a designated communication channel. After being on the channel, an assignment complete message will be sent to the RNS. See Fig. 1 signaling j, k, l, m

8) When the called party rings, the network sends an ALERTING message to the calling UE. See Fig. 1 signaling n;

9) When the called party answers, the network will send a CONNECT message to the calling UE. See Fig. 1 signaling o;

10) When the calling UE responds to the connection confirmation (CONNECT ACKNOWLEDGE) message, the call establishment process is completed. See signaling p in Figure 1;

2. Mobile terminated call establishment

After the CN receives the IAM message, if the incoming call is allowed to be established, the CN will use the radio interface signaling to page the UE. The UE responds with a paging confirmation (PAGE ACK) message, and the CN establishes a communication channel to the UE after receiving it. The mobile terminated call is used when the mobile user is called. At this time, the network initiates the call establishment process. The signaling diagram shown in Figure 2 includes:

1) CN sends a PAGE message to RNS, and RNS broadcasts the paging message on the paging channel. Refer to signaling A and B in Fig. 2;

2) The called UE monitors the paging and sends a channel request to the RNS, and the RNS responds with an immediate assignment message, instructing the UE to use the designated signaling channel. Refer to signaling C and D in Fig. 2;

3) The UE will send a paging response message on the signaling channel, and the CN will initiate the authentication and encryption process after receiving the paging response message from the UE. See Fig. 2 signaling E, F, G, H, I;

4) The CN sends a SETUP message to the RNS, which contains the bearer capability of the call. See Signaling J in Figure 2;

5) The UE receives the SETUP message from the RNS and responds with a CALL CONFIRMED message. If the negotiated bearer capability parameters change, the message should include bearer capability information. See signaling K in Figure 2;

6) CN receives CALL CONFIRMED message from RNS, CN will send RAB ASSIGNMENTREQ message to RNS to request wireless channel assignment, RNS will order UE to adjust to a designated communication channel by sending an assignment message to UE, UE adjusts to After being on the specified channel, an assignment complete message will be sent to the RNS. See Figure 2 signaling L;

7) The RNS sends a radio channel assignment response (RAB ASSIGNMENT RESP) message to the CN. See signaling M in Figure 2;

8) The called UE sends an ALERTING message to instruct the called user to ring. See Figure 2 signaling N;

9) When the called user answers, the called UE will send a CONNECT message to the CN via the RNS. See Figure 2 signaling 0;

10) The CN responds to the UE with a CONNECT ACK message, and the call establishment process ends. See Figure 2 signaling P.

3. Active call release process

After the mobile user completes the call, a message that the calling party or the called party hangs up will be sent to the network side, and an active call release process will be initiated. The specific release process is shown in the signaling diagram in Figure 3, including:

1) After the mobile party hangs up, the UE sends a DISCONNECT message to the network to initiate call clearing; see signaling a1 in Figure 3;

2) After receiving the message, the network sends a release (RELEASE) message to the UE; see signaling a2 in Figure 3;

3) The UE sends a release complete (RELEASE COMPLETE) message to the network. If the communication channel is no longer needed at this time, the corresponding channel release process is executed; see signaling a3 in FIG. 3 .

4 Passive call release process

After the mobile user completes the call, the message that the calling party or the called party hangs up will be sent to the network side, and the network side will notify the other party to initiate a passive call release process. The specific release process is shown in the signaling diagram in Figure 4, including:

1) The network sends a DISCONNECT message to the UE to initiate call clearing; see signaling b1 in Figure 4;

2) After receiving the message, the UE sends a RELEASE message to the network; see signaling b2 in Figure 4;

3) The network sends a RELEASE COMPLETE message to the UE. If the communication channel is no longer needed at this time, the corresponding channel release process is executed; see signaling b3 in FIG. 4 .

Figure 5 shows the flow chart of the existing 3GPP mobile phone call signaling, which specifically includes the following steps:

1) The calling UE sends a SETUP message to the called UE; see signaling A1 in Figure 5;

2) The called UE sends an ALERTING message to the calling UE; see signaling A2 in Figure 5;

3) The called UE sends a DISCONNECT message to the calling UE; see signaling A3 in Figure 5;

4) The network sends a RELEASE message to the calling UE and the called UE; see signaling A4 in Figure 5;

5) The calling UE and the called UE send RELEASE COMPLETE messages to the network; see signaling A5 in Figure 5.

The existing call rejecting and leaving message technology is the technology that the user manually rejects the incoming call and leaves a short message through the mobile phone or the mobile phone automatically rejects the incoming call and leaves a short message.

First of all, the called mobile phone user can preset one or more message messages that can be used as the text content of the call rejection message text message through a certain human-computer interaction interface, and store them in the called mobile phone user's mobile phone. Save it in the storage medium for backup, such as: "I'm in a meeting, so I can't answer your call" or "I'm very busy at work now, we're chatting after work" and so on.

When the called mobile phone user has an incoming call prompt, if the mobile phone user cannot or does not want to answer the phone call due to various reasons, he can choose to reject the incoming call and select a preset message as the incoming call rejection The text content of the message short message, send the call rejection message short message to the calling mobile phone user, and explain or explain the reason why the call cannot be answered at present, to show courtesy.

Of course, the called mobile phone user can also turn on the function of automatically rejecting incoming calls and leaving short messages by setting a sign. When the called mobile phone user turns on the function of automatically rejecting incoming calls and leaving short messages, the called mobile phone user does not need to manually intervene in the incoming call process. The system will automatically reject the incoming call and send a short message to the calling mobile phone user. The called mobile user presets the message information as the content of the automatic call rejection message short message.

Above-mentioned two kinds of mobile phone call rejecting message technologies are all realized by existing short message service, and its main shortcoming is: the called mobile user needs to pay the fee of leaving message short message; A large number of network signaling interaction processes caused;

Detailed ways

The call rejection method provided by the present invention mainly uses the user-user field specified in the 3GPP protocol to transparently transmit the call rejection message information of the called mobile phone user to the calling mobile phone user in the mobile communication network. Mainly, the called terminal obtains the call rejection message information locally from the terminal according to the enabled call rejection setting, adds the message information to the disconnection message, and sends it to the calling terminal. The called terminal can send the message message of rejecting the call in two situations. One is that the user sets the terminal to automatically reject the call, and the other is that the user sets the terminal to manually (not automatically) reject the call. The first type of automatic call rejection usually occurs after the called terminal receives the setup message sent by the calling terminal, and the called terminal automatically sends the rejected message information to the calling user. Through this method, the called user can prevent his own terminal from ringing, which is convenient for the called user to automatically reject the call without any impact in a place where it is inconvenient to answer the call, such as a conference or a movie theater. In the second case, after the called user's terminal rings, the called user rejects the incoming call. Different from the usual method, when rejecting the incoming call, the system will prompt to choose to send a message. Through this method of rejecting the incoming call, The user avoids spending extra short message charges to send a short message for rejecting an incoming call.

As shown in Figure 6, it is a flow chart of Embodiment 1 of the method for rejecting an incoming call of the present invention, which describes the call indication processing process of the called mobile terminal such as the called mobile phone: the called mobile phone receives The schematic processing process after the SETUP message sent by the mobile phone includes the following processing steps:

Step 11: The called mobile terminal receives the SETUP message sent by the calling mobile terminal, and judges whether the called mobile terminal enables the function of automatically rejecting incoming calls and leaving a message. If yes, perform step 12; if not, perform step 14; that is, when The called mobile phone does not send the ALERTING message immediately after receiving the SETUP message from the calling mobile phone;

Step 12: The called mobile terminal system automatically obtains the rejected message, and adds the message to the User-User field of the DISCONNECT message; the message is preset by the user through the rejected message in the mobile terminal The module is pre-set in the storage medium as a message message of rejection selected by default. That is, the called mobile terminal provides a man-machine interface such as the call rejection message preset module of a mobile phone, so that the user can select a call rejection message information and be set to the default call rejection message information, and The setting information is stored in the storage medium of the mobile phone user's mobile phone for use when automatically rejecting incoming calls and leaving messages. The module also provides a man-machine operation interface, so that the mobile phone user can modify and view the setting information stored in the storage medium of the mobile phone for obtaining the default call rejection message information.

Step 13: The called mobile terminal sends the DISCONNECT message added with the message information of rejection to the calling mobile terminal, ending the call;

Step 14: The called mobile terminal sends a ringing message to the calling mobile terminal, and the called mobile terminal generates a ringing signal.

Wherein, the User-User field involved in the embodiment of the present invention is a User-User field that can be included in the DISCONNECT message specified by the 3GPP protocol, and this field can be used to transmit user information between mobile phone users during a mobile phone call. The User-User field is transparently transmitted in the mobile communication network. The length of the field information is at least 3 octets, and the maximum is 35 or 131 octets (GSM network is 131, that is, if Use this field to transmit message information, up to 128 8-bit characters can be transmitted, which is equivalent to 64 Chinese characters).

Although the 3GPP protocol defines the User-User field in the DISCONNECT message, the 3GPP protocol does not specifically regulate the content and use of the field information, and the use of the field information can be specifically defined by the mobile phone terminal itself. The present invention transmits the message of the called mobile phone user by the User-User field in the DISCONNECT message, and the message includes:

1) Message ID: used to identify the message content transmitted by the User-User field as a message string;

2) Coding method: used to identify the coding method of the message string transmitted in the User-User field;

3) Message string: the message information transmitted through the User-User field.

The above technical solution utilizes the User-User field in the DISCONNECT message stipulated in the 3GPP protocol to transparently transmit the message information of the called mobile phone user to the calling mobile phone user in the mobile communication network, thereby avoiding the need to send a message message by using the short message service. A large number of network signaling interaction processes come, and the user needs to bear the cost of sending a short message every time he refuses to answer the call.

As shown in Figure 7, it is the flow chart of embodiment 2 of the method for refusing an incoming call of the present invention; that is, after the ALERTING message is sent as shown in Figure 6, the schematic processing process of the called mobile phone user rejecting the incoming call after step 14, that is, the called The schematic processing procedure for a mobile phone user to choose to reject this phone call during the ringing process of an incoming call:

Step 15: When the called user rejects the incoming call and sends a DISCONNECT message, the called mobile terminal system judges whether the function of non-automatic rejection of incoming calls and leaving a message is enabled, and if so, executes step 16; otherwise, executes step 18;

Step 16: The called mobile terminal system prompts the user to select and confirm whether to send the rejection message, and judge whether the called user confirms to send the selected message; if so, execute step 17; otherwise, execute step 18;

Step 17: The called mobile terminal system adds the message information in the User-User field in the DISCONNECT message, and sends the DISCONNECT message to the calling mobile terminal;

Step 18: The called mobile terminal system directly sends a DISCONNECT message to the calling mobile terminal to end the call.

As shown in Figure 8, it is the flow chart of Embodiment 3 of the method for rejecting an incoming call of the present invention. In the case that the mobile terminal of the called user shown in Figure 6 automatically rejects the incoming call or the called user shown in Figure 7 is ringing In the case of artificially rejecting an incoming call during the process, the called mobile terminal sends a DISCONNECT message to the calling mobile terminal. At this time, the calling user's call notification process is specifically shown in Figure 8:

Step 21: The calling mobile terminal receives the DISCONNECT message, and judges whether the message contains a User-User field, and if so, executes step 22; otherwise, executes step 24;

Step 22: Parsing and judging whether the content of the field is message information, if so, go to step 23; otherwise, go to step 24;

Step 23: Temporarily store the message, and set the flag of this message as yes, and execute step 25;

Step 24: Set the flag of this message message to none, and execute step 25;

Step 25: Process the subsequent communication channel release process normally;

Step 26: The system judges whether there is a message flag for this message, if there is, the message message is displayed, otherwise it is not displayed.

The calling mobile terminal (mobile phone) shown in FIG. 8 above obtains the message information of the called mobile phone user from the User-User field in the DISCONNECT message, and displays it to the calling mobile phone user.

The embodiment of the present invention skillfully utilizes the existing 3GPP mobile phone call signaling process shown in Figure 5 and the User-User field in the DISCONNECT message to realize the function of leaving a message when the called mobile phone user rejects an incoming call. The telephone user saves the cost of sending the short message, and on the other hand, can also avoid a large amount of network signaling interaction process caused by sending the short message.

At the same time, using the User-User field in the DISCONNECT message of the above-mentioned 3GPP protocol can also realize free sending of message information, thereby avoiding the need to send short messages through the short message center and the need to generate costs, and can save equipment utilization.

As shown in Figure 9, it is a schematic flow chart of Embodiment 4 of a method for calling and leaving messages by telephone. The method mainly uses:

Step 31: The calling terminal receives the ringing message from the called mobile phone user, and judges the type of this telephone call set, if it is a message type, then perform step 32; if it is a telephone call type, then perform step 33;

Step 32: the calling terminal adds a message to the disconnection message, and sends the disconnection message to the called terminal;

Step 33: The calling terminal displays the status of being connected to the called terminal normally.

This utilization of the telephone call mechanism can bring good cost savings to the user. This method is mainly that when a mobile phone user inputs or selects a mobile phone user's phone number from the phone book and wishes to initiate a phone call, the system first judges whether the mobile phone user's phone call message function activation flag is enabled, and if the phone number is not enabled If the call message function is used, the normal telephone call process is performed.

If the mobile phone user has enabled the telephone call message function, the system prompts the mobile phone user to select whether the type of this telephone call is a telephone call or a telephone message. If the mobile phone user selects a phone call, the phone call type flag is set to be a phone call type, and a normal phone call flow is performed. If the mobile phone user chooses to leave a message, then the type of this phone call is set as the information message type, and the system prompts the mobile phone user to input the content of the message, and the calling terminal waits for the called terminal to return a ringing message. Then initiate the phone call flow as described below.

The above message information is added in the User-User field of the DISCONNECT message, which is consistent with the description of the message information in Embodiment 1 of the method for rejecting an incoming call, and will not be repeated here. At the same time, after the called terminal receives the disconnection message, as shown in Embodiment 5 of Figure 10, the following steps are included:

Step 41: The called terminal receives the disconnection message, and judges whether the message contains a user-user field, and if it does, execute step 42; if not, execute step 44;

Step 42: The called terminal system analyzes and judges whether the field content is message information, if yes, then execute step 43; if no, then execute step 44;

Step 43: The called terminal stores the message information, and sets the message flag of this call as Yes;

Step 44: The called terminal sets the message flag of this call to None.

The called terminal creates a missed call record. If it is judged that the call message is marked as yes, the message is associated with the missed call record, and a missed call record carrying the message information is generated and stored; if it is judged that the call If the message flag is None, a missed call record without a message is generated and stored.

The called mobile phone user checks the missed call record, if there is a message in the missed call record, the missed call information containing the message information is displayed, and if not included, the missed call record information without the message message is displayed.

The present invention also provides a mobile terminal for rejecting incoming calls, which is provided with a processing system 101, a storage medium 102, and a sender/receiver 103, and also includes: a preset module 104 for rejecting incoming calls and leaving a message, and automatically rejecting incoming calls and leaving a message The flag setting module 105 is enabled and the non-automatic call rejection and message function enabling flag setting module 106 is enabled. That is, some functional modules are set on an existing mobile terminal such as a mobile phone, specifically as shown in Embodiment 1 of FIG. 11 :

Reject call message information preset module 104, used to provide a man-machine interface for users to set and/or modify at least one message message such as: "I am in a meeting, it is inconvenient to answer your call" or "I am very busy at work now, we In "chat", etc., and store them in the storage medium 102, and/or select a message from the at least one message to be set as a default call rejection message; that is, the call rejection message preset module simultaneously It also provides a man-machine operation interface, so that the mobile phone user can select a call rejection message and set it as the default call rejection message, and store the setting information in the storage medium of the mobile phone user's mobile phone for future use. Used when automatically rejecting incoming calls and leaving messages. The module also provides a man-machine operation interface, so that the mobile phone user can modify and view the setting information stored in the storage medium of the mobile phone for obtaining the default call rejection message information.
