Description

To control the call establishment process {CALL SETUP CONTROLLING METHOD}

The present invention relates to call control techniques, and more particularly to a method for controlling a call establishment process.

The user has to turn off the terminal device to avoid being disturbed by unwanted calls and to turn on the terminal device when a call is needed. The terminal device includes fixed terminals and mobile terminals, which are relatively easy to turn off. However, fixed telephones are inconvenient for the user, and disconnecting the telephone line is the only way to turn off the fixed telephones. In addition, turning off terminals, whether mobile or fixed, presents other problems. When the terminal device is turned off, the user cannot receive any call calls and other users cannot make calls to the user even if they have important business tasks. The user then turns the terminals back on when needed. Mobile terminals are convenient to turn off and on, but users generally forget to turn on fixed terminals. Thus, users will not be able to receive phone calls from anyone else unless the fixed terminal is turned on again.

In addition, users may use a secret service currently provided by a mobile communication system. However, the service only applies to mobile terminals. A user who is a mobile terminal is able to adjust the settings of a secret station. In one example, a user who does not wish to be disturbed by a call can have the calling user record a voice message at the secret station and send the message to the user. Thus, when a secret service receives a call for a user, it asks the calling user whether to leave a message, and the called user is informed by short messages or other means. The called user calls the secret station to receive a voice message left by the calling user. Since the called user can determine whether to make a response call according to the content of the voice message, the called user can not be disturbed by the incoming call.

However, the secret service is a paid service. In other words, the service user has to pay for the service. Since the secret station switches the incoming call to a short message or other means for notifying the called user, the user is still interrupted by receiving the short presentation or other messages instead of the phone call. Therefore, this method is not perfect. Additionally, the short message from the secret station may or may not be delivered in time to the user receiving the call, since the short message is not delivered or delivered. For example, the short message is not a real time communication, and since the user sets a short message notification sound such as a silent mode, a bass mode, or a silent mode, the user sometimes fails to check the short message in a timely manner. In other words, you can't handle urgent business in a timely manner.

Another solution is to set up an incoming call filter. For example, you can use blacklists and whitelists to not miss important phone calls and protect them from disturbing non-critical calls. In one example, the method of using the whitelist sets a whitelist of call numbers that allow a calling terminal to access and only white when the terminal receiving the call has activated the whitelist function. Only the calling terminal on the list can access the terminal receiving the call. The whitelist method is a solution that can solve the problems mentioned above, but authenticated call terminal numbers can only be limited. If user A needs to call user C in an emergency situation, assuming that user A's mobile call number is on the whitelist but user A calls on user B's mobile phone and his mobile phone is powered off, A cannot call through a number in the whitelist, so user A cannot call user C. The method of using the blacklist includes setting a blacklist of call numbers that are not allowed to access a receiving terminal, and when the call receiving terminal has activated the blacklist function, the incoming in the blacklist. The call is rejected. In the blacklist method, it is impossible to refuse reception of a call from a number other than the blacklist. For example, a blacklist solution may not reject unnecessary calls from public phones. Moreover, the management of the blacklist and whitelist is more complicated.

Accordingly, the present invention provides a method for control of a call establishment process to ensure that a terminal device can make calls with only important calling terminals in certain circumstances.

Specific solutions according to the present invention are as follows.

A method for controlling a call establishment process includes setting group codes in a called terminal, sending a calling number and a corresponding group code to the called terminal; The called terminal determines whether the received group code is one of the group codes set in the called terminal, and if the received group code is one of the group codes of the called terminal, the call number Allowing a call to be established between a corresponding calling terminal and the called terminal; otherwise, rejecting the call.

The step of allowing a call to be established between the calling terminal and the called terminal corresponding to the calling number includes returning a call back indicating that the called terminal is allowed to call.

The callback returned by the called terminal is a callback for the call number corresponding to the group code, and the call terminal corresponding to the call number, after receiving the callback from the called terminal. Initiating a call to the called terminal.

The step of the called terminal rejecting the call further includes the called terminal returning a callback indicating that the call was rejected.

The callback returned by the called terminal further includes a reason for rejecting the call.

Before the called terminal returns the callback, the called terminal needs to confirm whether the called user will send the callback, and if the answer is positive, the called terminal returns the callback. Returning, otherwise the called terminal cancels the callback.

The callback returned by the called terminal may be any one of a short message, a voice call, or user-to-user signaling (UUS).

The step of setting group codes in a called terminal includes setting group code properties indicating whether the callback is to be sent for the group code stored in the called terminal, Prior to sending the callback, the called terminal obtains the group code attribute corresponding to the group code and determines whether to send the callback according to the obtained group code attribute.

The step of setting group codes in a called terminal includes setting a pre-call call number registry in the called terminal, wherein the called terminal is connected with the calling terminal corresponding to the calling number. The step of allowing a call to be established between the called terminals comprises the calling terminal registering the call number in the pre-call call number registry.

After the called terminal registers the call number in the pre-call call number registry, upon receiving the incoming call, the called terminal is further configured to call the pre-call call of the incoming call. Determine whether it is in a number registry, and if the called number of the incoming call is in the pre-call call number registry, the called terminal connects the incoming call to the called user; The called terminal further rejects the incoming call.

The called terminal determines whether the received group code is one of the group codes set in the called terminal, and if the received group code is one of the group codes of the called terminal, the call number Pre-call registration including at least the call number information for the called terminal after the step of allowing a call to be established between a corresponding calling terminal and the called terminal, and otherwise rejecting the call. Sending a cancel command and after the called terminal receives the pre-call registration cancel command, deleting the call number from the pre-call call number registry.

The pre-call deregistration command further includes the group code, and before the called terminal deletes the call number from the pre-call call number registry, the called terminal is assigned to the call terminal. Determining whether the group code is one of the group codes set therein, and if the group code is one of the group codes set in the calling terminal, deleting the call number; otherwise, rejecting deletion of the call number It further includes.

The step of setting group codes in the called terminal sets, in the called terminal, scenarios that the group codes need to establish the call, the scenario and the group codes. Establishing a matching relation between and wherein determining that the called terminal is one of the group codes set in the called terminal further comprises: calling the called terminal; Determining whether the received group code matches a current scenario based on the matching relation set in the called terminal.

The step of setting group codes in a called terminal further comprises setting up a pre-call call number registry in the called terminal, wherein the called terminal is connected with a calling terminal corresponding to the calling number. Upon allowing a call to be established between the called terminals, the called terminal further includes registering the call number and the corresponding group code with a pre-call call number registry.

When the called terminal receives the call, retrieving the corresponding group code of the call number in the pre-call call number registry and the called terminal is returned to the retrieved group code in the current scenario. And if the retrieved group code matches the current scenario, the called terminal is connected to a current call; otherwise, the called terminal rejects the current call. It is characterized by.

The called terminal determines whether there is a group code that does not match the current scenario in the pre-call call number registry, and if there is a group code that does not match the current scenario in the pre-call call number registry. And if the called terminal deletes the information related to the group code from the pre-call call number registry.

The step of setting group codes in a called terminal further comprises setting up a pre-call call number registry in the called terminal, wherein a call is placed between a calling terminal and the called terminal corresponding to the calling number. When allowing to be established, the called terminal further comprises registering the call duration and the validity period allowing the call from the calling terminal corresponding to the calling number to be established.

Upon receiving the call, the called terminal further comprises obtaining the corresponding validity period according to the call number of the call in the pre-call call number registry.

Determining whether the called terminal is a validity period according to the call number registered in the pre-call call number registry, and if it is not a validity period according to the call number registered in the pre-call call number registry; And said called terminal further comprises deleting said related information of said call number.

When the called terminal receives the call, in performing the determination according to the pre-call call number, when receiving the call, the called terminal has the call number set to the pre-call call number registry. The called terminal is directly connected to the current call if the call number is stored in the pre-call call number registry; otherwise, the called terminal rejects the call. It includes more.

Upon receiving the call, the called terminal determines whether the call number is stored in the pre-call call number registry, and if the call number is stored in the pre-call call number registry, the called The terminal is directly connected to the current call; otherwise, the called terminal further includes rejecting the call.

Before the called terminal connects the current call, the called terminal obtains the corresponding group code of the call number, determines whether the group code matches the current scenario, and the group code The call terminal is connected to the current call if is matched to the current scenario, otherwise the call terminal rejects the call.

The scenario may be a group code call period or an emergency situation.

Both a group code call period and an emergency situation are set in the calling terminal, and the step of determining whether the called terminal is one of the group codes set in the called terminal, wherein the called terminal is Determine whether the received group code matches both the group code call period and the emergency, and if the received group code does not match either the group code call period or the emergency The called terminal determines whether the group code matches the current scenario, and if the received group code matches the group code call period and the emergency, the called terminal is configured to display the group code in the current scenario. Determine whether the group code call period is matched, or if the group code is Determine whether any one of all the group codes corresponding to either the current emergency situation or the current group code call duration or the current emergency situation, or both the current group code call duration and the current emergency situation This includes determining whether to match all of them.

Setting a super group code corresponding to all scenarios in the called terminal.

Setting a level of all group codes and a level of all scenarios in the called terminal, wherein the called terminal determines whether the received group code is one of the group codes set in the called terminal. The step further includes the called terminal determining whether the level of the received group code is higher than the level of the current scenario.

The step of setting group codes in the called terminal comprises: setting a maximum number for transmitting incorrect group codes in the called terminal, and all of the above having transmitted more incorrect group codes than the maximum number of times. Setting a blacklist for recording call numbers, wherein the called terminal determines whether the received group code is one of the group codes set within the called terminal; Determine whether a corresponding call number of code is in the blacklist stored at the called terminal, and if the corresponding call number of the group code is stored in the blacklist stored at the called terminal Terminal rejects the call from the call number and the processor Terminating the call, otherwise, the called terminal determining whether the received group code is one of the group codes set in the called terminal, and the called terminal dials the call. Prior to rejecting, the called terminal determines whether or not a number corresponding to transmitting the call number and incorrect group codes is stored in the called terminal to determine the call number and incorrect group codes. If the number corresponding to the transmission is not stored in the called terminal, the called terminal records the call number and sets the number of incorrect group codes, otherwise the called terminal previously 1 is added to the number of recorded incorrect group codes, and the incorrect group codes after the sum Determine whether the number of pieces exceeds the maximum number of incorrect group codes set in advance, and if the number of incorrect group codes after the sum exceeds the maximum number of incorrect group codes set in advance, the call And the called terminal adds the call number to the blacklist, otherwise the called terminal further does not add the call number to the blacklist.

The present invention provides a solution by group code function. When the called terminal user does not want to be disturbed by a frequently incoming call, a group code call is required for every incoming call in the scenario to send the group code corresponding to the called terminal. ) Function can be activated. If the calling user does not get the correct group code from the called user, the user is guaranteed that the call is not connected to the called user and therefore is not disturbed by an unimportant or unnecessary call when the called user does not want to. Can be. In addition, family and friends of the called user can obtain the correct group code from the called user, so that they can talk to the called user via telephone. Thus, it can also be ensured that the called user does not miss important phone calls.

According to a specific solution of the present invention, the called user is able to classify the calling user, and it is possible to assign different priority levels to the calling users with the different group codes, so that of the received calls You can set the range flexibly. Also, by setting the group codes, the users can change the calling user group without changing their calling number. Thus, if the user frequently receives unnecessary telephone calls, the user can reject such telephone calls by setting the group code. In addition, even when the unnecessary calling user gets the group code of the called user, the called user can reject the calls through changing the group without changing the actual calling number. This means that the user can change the group codes instead of changing the call number, effectively rejecting unnecessary calls and ensuring the user's daily work and life.

In addition, the specific solution of the present invention can solve the problem of automatic management of the white list. For example, when the whitelist stores a call number of a user whose white list of the called terminal is 13923812345, all of the user's cellular phones are exhausted and the user is fixed. Phone call by an old phone. Since the call number of the fixed telephone is not in the whitelist of the called terminal, the fixed telephone cannot make a connection for the call with the called terminal. However, if the fixed telephone sends the user's own group code set by the called terminal to the called terminal via a short message or UUS signaling, the called terminal confirms the group code and Register the number of the fixed telephone in a pre-call calling number registry, and the user can connect the fixed telephone to the called terminal. If the fixed telephone does not support short service or UUS service, the user can use another person's cellular phone to send the fixed telephone number and the corresponding group code to the called terminal.

In summary, the method of establishing a call according to the present invention can ensure the convenience that the called user can not miss an important telephone call and can not be disturbed in a specific environment.

In addition, the solution of the group codes according to the present invention can be easily employed by the operators, since the operators can increase the revenue for the service.

According to a solution provided by the present invention, the called user first sets specific group codes in the called terminal. When the calling terminal A needs to be connected with the called terminal B, the calling terminal A sends the call number and the corresponding group code to the called terminal B. The called terminal B determines whether to connect to the terminal A based on the received information. After the calling terminal B decides to accept the call received from the calling terminal A, terminal B initiates a call back directly to terminal A and a telephone call between terminal A and B is established through the callback. Can be. If the called terminal B is determined to accept the call received from the calling terminal A, the terminal B also simply registers the call number received from the terminal A. Terminal A then initiates the call to terminal B, which determines whether to accept the call received from terminal A based on the relative information registered in the registry. For example, the called terminal Terminal B determines whether the call number is registered in the registry. If the call number is registered in the registry, the current call may be connected to the called user, otherwise the called user will reject the current call.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and specific examples.

1 is a diagram illustrating a flowchart according to a first embodiment of the present invention. The first embodiment consists of the following steps.

Group codes are set in the called terminal B (S101).

For example, in some scenarios, when the called user is in an important meeting or is sleeping at midnight, the called user wants only a few family members and close friends to be able to call. Thus, the called user can set up some group codes and inform the group codes only to those mentioned above, so that they can be the only people who can connect to the called terminal. Indeed, the group code here may be the only password for accessing the called terminal of the called user.

The calling terminal A transmits the call number and the corresponding group code to the called terminal B (S102).

The calling terminal A sends the call number and the corresponding group code to the called terminal B, via a short message or a user-to-user (UUS) signal, a multimedia short message, or an e-mail. Can transmit

If the transmission of the call number and the corresponding group code from the calling terminal A to the called terminal B can be realized by a short message or UUS, the short message or UUS may contain the group code or call number. have. Indeed, if the called terminal B supports the call number recognition function, the calling terminal A can send the call number to B by the call number recognition function, so that the short or UUS only transmits the group code. There is a need.

The called terminal B determines whether the received group code is one of the set of group codes of S101; If the received group code is one of the set of group codes in S101, the called terminal B may accept a call from the calling terminal A, otherwise the call from the terminal A is rejected. And the process ends (S103, S104, S105).

According to the solution according to the invention, when accepting a call from calling terminal A, the called terminal B can further initiate a callback to the calling terminal A and the callback can be connected to the calling terminal A. This process can be implemented by the second embodiment of the present invention shown in FIG.

When the called terminal B rejects the call from the calling terminal A, for example, the called terminal determines whether the received group code is one of the group codes in S201, and the The called terminal B may also send a message to the terminal A, indicating that the called terminal B has refused to establish a call between the calling terminal A and the called terminal B, the message further comprising a reason for the rejection. Can be configured. For example, the calling terminal A may use a group code not preset in the called terminal B, and the calling terminal A may notify the calling user of the message.

In the second embodiment, the called terminal B initiates the callback, and the callback may be a short message or a voice call to the calling terminal A, and may also be, for example, in the form of a multimedia short message or a UUS. Can be. The calling user A generates another response according to the difference in the form of the callback. For example, if the called terminal B sends a short message as a callback, the called terminal B also grants an acknowledgment for establishing a call between the calling terminal A and the called terminal B in the short message, The terminal A may be notified. The calling terminal A initiates a call after receiving the short message, and the call initiated by the calling terminal A may be a voice call, a multimedia short message, or another form. If the called terminal B initiates a voice call as the callback, the calling terminal A may connect directly to the voice call to establish the call to the called terminal B. The called terminal A may also reject the callback when it receives the callback from the called terminal B and may automatically initiate a call to the called terminal B. If the callback is a short message, a multimedia short message, or a UUS, the calling terminal A may be associated with the callback and automatically initiate a call to the called terminal B.

The second embodiment of the present invention, before initiating a callback, the called terminal B notifies the called user and waits for the called user's response. If the called user confirms the callback, the called terminal B initiates the callback to the calling terminal A; otherwise, the called terminal B rejects the callback and determines the process. For example, the called terminal B notifies the callback request with voice notification while displaying a notification message on the screen asking the called user, "Do you want to call back?" The called user may confirm the callback by pressing a key corresponding to “Yes” or may reject the callback by pressing a “Cancel” key.

In the second embodiment of the present invention, the group code attribute may be set for each group code, and the called terminal B may respond based on the attribute value of the group code. For example, attribute value 0 indicates call terminal A callback via voice call, attribute value 1 indicates callback via short message, and attribute value 2 indicates rejection of the callback.

Further, the third embodiment according to the present invention proposes a more advanced form based on the first embodiment and the second embodiment. In a third embodiment, a pre-call telephone registry, in short, a pre-call registry, is set up in the called terminal B. When the called terminal B allows a call from calling terminal A, the call number may be stored in the pre-call registry to establish a call between the calling terminal A and the called terminal B. Thus, even if the called terminal B fails the callback, the calling terminal A can still call the called terminal B. When the calling terminal A calls the called terminal B, the called terminal B may determine whether to connect the call according to the pre-call registry.

In a third embodiment, according to a call number stored in the pre-call registry, a detailed procedure for allowing the call number to allow a call to establish a call between the called terminal B and the calling terminal A includes the following. do. Upon receiving a call from the calling terminal A, the called terminal B determines whether or not the corresponding call number of the current call is stored in the called terminal B's registry so that the corresponding call number of the current call is determined. If stored in the registry of the called terminal B, the current call may be connected by the called terminal B to the called user, otherwise the called terminal B may reject the current call.

On the other hand, the pre-call registration according to the third embodiment can be cancelled. For example, the calling terminal A may send a pre-call deregistration command to the called terminal B when the calling terminal A cancels the pre-call registration. The command may be confirmed by a negative value of the group code. For example, a group code is transmitted using the negative value indicating to cancel the pre-call registration. In addition, command codes may be used to distinguish between the registration command and the deregistration command. After the called terminal B receives the deregistration command, it can cancel the corresponding pre-call registration. The deregistration command may include the corresponding call number and the group code. Before canceling the pre-call registration, the called terminal B determines whether the deregistration command is valid. For example, it is determined whether the group code is one of the group codes in the called terminal, and if the command is valid, the corresponding registration entry is determined according to the call number, the pre- It can be searched outside of the call registry and then deleted.

When the called terminal B calls back to the calling terminal A, the calling terminal A automatically calls back to the called terminal B after receiving an acknowledgment for establishing a call to the called terminal B. The callback from calling terminal A may be a voice call or a multimedia short message, or another form of call. For example, based on the second and third embodiments, the calling terminal A determines whether the information in the callback includes an authorization to establish the call to the called terminal B, If the information in the callback includes an acknowledgment to establish the call to the called terminal B, the calling terminal A may call back the called terminal B, otherwise the calling terminal A may call back Cannot be started.

In general, in the aforementioned embodiments, limited application of the other services may be realized by the unlimited short message service method. For example, the short message may be used to control services such as the voice call, the multimedia short message, and the like. Further, in practical application, the limited application of the short message service can also be realized through the infinite voice service methods. By such a solution, limited applications of other services can also be realized.

In practical applications, in general, a user wishes to be able to receive a call, within scenarios, over a certain period of time or through a specific group code within a certain environment. In order to solve this problem, the user sets a matching of pairs of group codes and the corresponding scenarios in the called terminal. The scenario may be a call period of a group code, such as a period of time between 00:00 and 06:00, or an emergency situation such as when the user is in an urgent meeting.

Furthermore, at the same time as the above situation, the above-described embodiments may also establish the matching relationship with the scenarios between the group codes and the scenarios. As an example, in the first embodiment, the called terminal B determines whether or not the received group code is one of the group codes, and the received group code and the current scenario correspond to the group codes. The called terminal may determine whether to fulfill the matching relationship of the scenarios (fulfilling). For example, the called terminal B may retrieve the corresponding group codes according to the current scenario and matching relation, wherein the retrieved group codes receive the group code received from the calling terminal A. It can be determined whether or not to include. If the retrieved group codes include the group code received from the calling terminal A, the matching relation is performed, otherwise the matching relation is not performed. The called terminal B also retrieves the corresponding scenarios according to the received group codes and the matching relation, and determines whether the retrieved scenarios include the current scenario.

For the matching relation between the scenarios and the group codes, if the called user can determine that he or she does not want to be disturbed for one or some period of time, a group code call period can be set, each set Group Code Call Duration One or more corresponding group codes may be set. Thus, for a certain period of time, only users with the corresponding group codes can be associated with the called user. In addition, when the called user is in a meeting or other urgent situation, or in a special situation such as during a concert viewing, and when the called user does not want to be disturbed, an emergency situation can be set. One or more corresponding group codes can be set. For example, the called user can establish the matching relation between the groups and the specific emergency, so that only a user who knows the corresponding group codes in an emergency can be connected with the called user. have. For example, the emergency setting includes setting one or more emergency levels in the called terminal, and may include an emergency meeting level, a concert level, and the like. Emergency levels are used to identify emergency situations, for example, in which the normal level indicates a corresponding group code and non-emernecy cases. Or more emergency levels and one normal level may be set.

Scenarios of the calling periods of the group codes, which means that the calling period of the group code may also be in an emergency situation, may overlap with the scenarios of the emergency situations. Referring back to the first embodiment, when there are overlapped scenarios, S103 may further include the following. The called terminal B determines whether the received group code is the group code corresponding to a current group code call period, or whether the received group code is the group code corresponding to the current emergency situation. Determine whether or not the received group code belongs to an intersecrion of the group codes corresponding to the group code reception period and the group codes according to a current emergency, or the received group Determining whether the code belongs to the union of the group codes corresponding to the current group code call duration and the group codes according to the current emergency.

In S103, the called terminal B may also directly determine whether the received group codes are the application of group codes in S101, and the determining may include the receiving of the received group code by the received terminal B. Determining whether or not the group code corresponding to the current group code call period, or whether the received group code is a group code corresponding to the current emergency, or according to the current group code receiving period and the current emergency It is determined whether to belong to the intersection of the group codes corresponding to the group codes, or the received group code, the group code corresponding to the group codes according to the current group code call period and the current emergency situation Determining whether or not belonging to the combination of the two.

Obviously, the called terminal B must first acquire the current scenario when an incoming call arrives, and if the called terminal B is not in both the scenario of the group code call period or the emergency scenario, The called terminal B processes the incoming call according to the normal processing. In other words, the called terminal B may be directly connected to a voice call, or a multimedia short message. When the calling terminal A sends the call number and the corresponding group code to the called terminal B, the called terminal B discards the information.

The following discussion focuses on the called terminal B's response when an incoming call arrives, either in a group code call duration scenario or in an emergency scenario. The fourth embodiment according to the present invention is a detailed embodiment based on the third embodiment of the present invention, while further setting scenarios and the matching relation between the group codes and the scenarios. The process is shown in FIG.

The matching relationship between the group codes and the scenarios, as well as the pre-call call number registry, the group codes, and the scenarios, is established in the called terminal B (S310).

The call user A transmits a group code corresponding to the call number and the called terminal B (S302).

In S301, the called terminal B obtains a current scenario, and retrieves all the group codes that match the current scenario corresponding to the matching relation setting (S303).

The called terminal B determines whether the received group code is one of the group codes retrieved in S303 (S304).

If the received group code is one of the group codes retrieved in S303, the called terminal B registers the call number, accepts a call from the calling terminal A (S305), otherwise the call Terminal B does not register the call number, rejects the call from the calling terminal A, and terminates the process.

The matching relation between the scenarios and the group codes and the scenarios may also be set based on the second embodiment, which does not register the call number in S305. Instead of the called terminal B making a direct callback to the calling terminal A in S305, the called terminal B directly rejects the call from the calling terminal A in S306.

When the scenarios are set up, the called terminal B may also send a rejection reason to the calling terminal when rejecting the call from the calling terminal. For example, the called terminal B may transmit a reason for rejection to the calling terminal through a short message, UUS, or the like. The reason for the rejection may be that the received group code is not one of the preset group codes in the called terminal B, or the received group codes do not match the current scenario.

In a practical application, even if the called terminal has been terminated before registration, the called terminal may be connected to a call that has been changed to the incoming user but the scenario has changed at the time of registering the scenario. The changed scenario may receive a group code that does not match. At the time of the situation, the call number registry in the called terminal may further include the group code received at the time of registering the call number. The relative pre-call registry is shown in the following table.

When the called terminal B registers the call number in S305, the corresponding group code may also be registered. The registry substantially stores the matching relation of the call number and the corresponding group codes. Thus, when the called terminal arrives, the called terminal may retrieve the corresponding group code from the registry according to the call number, and determine whether the retrieved group code matches the current scenario. Can be. If the retrieved group code matches the current scenario, the current call is connected to the called user, otherwise the current call is rejected. The operation of the called terminal B in more detail when receiving a call in the above situation is described in the fifth embodiment. 4 shows a process according to the fifth embodiment.

The calling terminal A initiates a call to the called terminal B (S401).

When the call arrives, the called terminal B determines whether the call number of the current call is stored in the registry of the called terminal B, so that the called terminal B has the call number of the current call. If it is stored in the registry of the terminal B, the called terminal B proceeds to S403, otherwise proceeds to S405.

From S403 to S404, the called terminal B determines whether or not the corresponding group code of the call number in the registry matches the current scenario, so that the corresponding group code of call number in the registry is determined in the current scenario. If the, the current call is connected to the called user, otherwise the called terminal B proceeds to S405.

The called terminal B rejects the current call (S405).

The called terminal can determine the information in the registry when a call needs to be connected. If a group code does not match the current scenario, the group code and the corresponding call number may be deleted from the registry. The called terminal continuously determines whether the telephone number of the current call is stored in the registry, and if the telephone number of the current call is stored in the registry, the current call can be connected to the called user. Otherwise, the current call is rejected.

In the fifth embodiment, before registering the call number in S304, the called terminal B determines whether the group code transmitted by the call terminal is the group code corresponding to the current scenario. Can be skipped. For example, the process of determining whether the received group code matches the current scenario can be omitted. Instead, the called terminal B is set by the called user before the received group code registers the matching relation between the group code sent by the calling terminal and the corresponding call number. Determine whether it is one of group codes. In such a situation, according to the fifth embodiment, when a call needs to be connected to the called user, the called terminal determines whether the group code according to the call number of the call matches the current scenario. Based on the determination, whether to connect the current call can be determined. Thus, the scenario function of the whitelist can also be realized. In other words, the pre-call registry entries may be stored, but only a call corresponding to a call number in the pre-call registry may be associated with the called user in a particular scenario.

If the scenario changes and the group code no longer matches the current scenario, the called terminal may determine whether the information is in the registry before the call connects. If a particular group code does not match the current scenario, the group code and the corresponding call number can be deleted from the registry, and the called terminal determines whether the current call is stored in the registry. . If the call number of the current call is in the registry, the current call may be connected to the called user, otherwise the current call may be rejected. Another solution is that when the scenario moves from one side to the other, the called terminal actively searches for the group codes in the registry. If a particular group code does not match the current scenario, the called terminal may delete the group code and the corresponding call number. Thus, after a call arrives based on a determination of whether the corresponding call number is stored in the registry, the called terminal may directly perform the determination.

The called terminal may also check the registry regularly and delete group codes and corresponding call numbers that do not match the current scenario. Thus, the volume of data in the registration is limited. However, the regular deletion does not guarantee that the group code exactly matches the current scenario. Thus, the called terminal should still perform the working process described in the fifth embodiment when the call is received.

Based on the pre-call registry in the third embodiment, the registry may further comprise designating a time for allowing establishment of a call by calling terminal A. The specified period may start at the registration time and last for a preset length. The corresponding pre-call registry is shown in the following table.

Thus, when the calling user has gone through the pre-call registration process, the called terminal allows the user to call within a specified period. When calling the called terminal, at other times than the specified time period, the call still requires a pre-call registration process. The called terminal may delete the entry of the pre-call registration that is out of time.

If scenarios have been set, for example, in a scenario of a group code call period, the registration time may be set as a start point of the designated period, and an end time of the current group code call period is It can be set as an end point. In an emergency scenario, the registration time may be set to a market point of a specified period, and a preset duration of a specific emergency may be set to a duration of a specified period, or of all the emergency situations. The preset general duration may be set as a duration of a specified period. The corresponding pre-call registration registry is shown in the following table.

As shown in the table, in S303 and S304 of the fourth embodiment, the called terminal B first determines whether the group code transmitted by the call number A is a corresponding group code of the current scenario. can do. For example, it is determined whether the received group code matches the current scenario. If the group code matches the current scenario, the called terminal B registers the call number and the designated period of the calling terminal A, otherwise the called terminal B will not register the call number. Can be determined. From S402 to S405 of the fifth embodiment, when an incoming call arrives, the called terminal B determines whether the call number is registered, and the call time of the current call is for a corresponding designated period of the call number. Depending on the authorization, it may be determined whether to directly connect the current call.

When the pre-call registry of the called terminal B further includes the designated period of the calling terminal A, the judging process of the called terminal B is shown in the sixth embodiment of the present invention of FIG. 5 is a flowchart showing a detailed operation procedure when the called terminal B receives a call.

The called terminal A initiates a call to the called terminal B (S501).

When the call arrives, the called terminal B determines whether or not the call number of the current call is a call number stored in the registry of the called terminal B, so that the call number of the current call is the number of the called terminal B. If the call number is stored in the registry, the called terminal B proceeds to S503, otherwise proceeds to S505 (S502).

From S503 to S504, the called terminal B determines whether or not the call time of the current call is a specified period corresponding to the call number of the registry, so that B is the designated time period that the call time of the current call corresponds to the call number of the registry. If, then the current call may be connected to the called user, otherwise the called terminal B proceeds to S305.

The called terminal B rejects the current call (S505).

For example, the user sets three group code call periods and two priority levels on the user's terminal. The two priority levels are zero indicating normal level. The level corresponding to the group code of the emergency is 11112222. The emergency level may also be a random fixed value other than zero. The emergency level of the present invention is superior to the group code call periods. In other words, when the called terminal is at an emergency level, the calling terminal has access to the called terminal with a group code corresponding to the group code calling period, even if the calling time is the group code calling period. cannot be accessed. The three group code call periods are as in the table below.

The group code for family members is 66688888, the group code for friends is 22236789, and the group code for colleagues is 33123456. According to the settings in Table 4, a call with group code 66688888 can be accessed at any time to the called terminal, and a call with group code 22236789 can only be accessed from 19:00:00 to 23:59:59 to the called terminal. The call with group code 33123456 can only be accessed from 19:00:00 to 23:00:00 at the called terminal.

For example, the calling user sends a group code to the called terminal before calling the called terminal user. For example, the transmitted group code is 11112222. The called terminal may determine whether it is an emergency level. In the case of an emergency, upon confirming that the group code corresponds to the emergency level, the called terminal may obtain a call number and register a matching relation between the group code and the call number directly. In case of non-emergency level, it may be determined which of the group code call periods the called terminal is. In the case of a group code call period, after confirming that the received group code is not a group code corresponding to the group code call period, the called terminal may reject pre-call registration of the call number. If not in any scenario, the called terminal can connect the current call directly to the user when the calling user makes a call. If not in any scenario, when the calling user sends a group code to the called terminal, the called terminal may discard the group code without executing any process.

The called user can also set a valid super group code in any scenario. Thus, regardless of what scenario the called terminal belongs to, when the calling party initiates a call to the called terminal using the super group code, the called terminal is called. Can be connected to. Thus, the user can inform family members and friends of the super user of the super group code that they can connect to the called user at any time via the called terminal. Thus, it is very convenient for the calling user and the family members or friends of the called user to be contacted.

In the above example according to the present invention, the user sets group codes and corresponding call numbers in the user's terminal, and also sets group codes and corresponding emergency situations.

In fact, the called terminal can also establish matching relations between the group codes and the scenarios through levels. For example, the called terminal can assign a level for each group code, and can assign a level for each scenario. Thus, the calling user can access the called terminal by a group code according to the level of each scenario having a level. Thus, it may be more convenient to establish a relationship between the group codes and the scenarios.

For example, in the fourth embodiment, the called user may further set group code levels in the called terminal B in order to have more flexibility in controlling the incoming call. That is, when the user does not want to be disturbed between 00:00:00 and 24:00:00, the user may only respond to calls from family members such as parents or children of the user, and the user May assign level 2, which is the highest group code level, during the period of time. During the period between 07:00:00 and 08:00:00, or 23:00:00 and 24:00:00, the user also allows calls from close friends, in addition to calls from the family members, The user may assign Level 2, which is the second highest group code level, during that period of time. In this way, the user can assign a group code level to each group code call period. The user may set one or more group codes and assign a level to all group codes. Thus, the relation of the group code call periods and the group code level can be established in the terminal as shown in Table 5. And, as shown in Table 6, a relation between the group codes and the group code levels can also be established in the terminal.

Of the group code levels of Tables 5 and 6, level 1 is the highest level, and therefore, the group codes according to level 1 are super group codes. In practical application, being able to set the group codes to a higher level is also valid at a lower level. During the call period of level 2 group codes, for example, from 23:00:00 to 24:00:00, the level 1 group code 666668 is also valid at the called terminal B.

When the group code levels are set, the called terminal can register or connect to the current call according to the level information. When registering a matching relation between the call number and the group code, the called terminal determines whether the group code matches the current scenario corresponding to the group code level. While determining whether the group code used by the current call is the corresponding group code of the current scenario, the called terminal obtains a scenario level corresponding to the current scenario, and the group code level of the current group code. To repent. When the group code level is equal to or higher than the current scenario level, the group code may be valid in the current scenario.

Several group code call periods are set in the above-mentioned embodiment, and in an actual embodiment, the user can flexibly set the group codes and the call periods at the user's needs.

According to an embodiment of the present invention, the maximum number of incorrect group codes may be further set. When the calling terminal sends the group code to the called terminal, if the number of the incorrect group codes sent by the calling terminal exceeds the maximum number of the incorrect group codes, the called terminal is the The call number will be blacklisted. For example, with a number such as 10, the maximum number of the incorrect group codes can be set as needed. Based on the settings, while receiving the group code sent by the terminal, the called terminal may first determine whether the call number is blacklisted. If the call number is in the blacklist, the call from the call terminal may be rejected. Otherwise, the called terminal may proceed by the aforementioned steps to confirm the group code.

The function of automatic blacklisting makes it very difficult to attack group codes through the method of infinite enumeration, and can effectively prevent hostile attacks on group codes. In a practical embodiment of the present invention, the called user's friend will be blacklisted just because he forgot the group code. In such a situation, the friend may be able to contact the called user by other means, such as a normal short message. The called user can, after verifying the identity of a friend, remove the friend's number from the blacklist and inform the friend of the correct group code. If the called terminal supports the short message service, a calling user, that is, a friend, may contact the called user through the short message, and the called user is based on the short message. Determine whether is valid. If the calling user is valid, the called user can manually delete the call number from the blacklist and inform the calling user of the corresponding group code. Thus, the present invention provides more convenience to the user without any problem. After granting the call from the calling terminal, the called terminal may determine whether a number corresponding to the call number and an incorrect call is recorded at the called terminal. If the called terminal has a number corresponding to the call number and an incorrect call recorded in the called terminal, the record is deleted.

According to an embodiment according to the invention, according to an infinite number of different call types depending on the calling user, the call number may be a terminal number or a personal number.

In the embodiment of the group code calls, the friends of the called user are not unable to contact the called user just because the calling user has changed the calling codes of the calling user. Unless the called user changes the contactable number of the called user, the calling users may contact the called user through the contactable number for another period of time, and the called terminal If the caller supports the short message service, the calling users can contact the called user at any time through the short message. This is quite different from the existing situation where older friends cannot contact because the called user has changed the called user's phone number. Thus, the group code call function can effectively meet the practical needs of users.

Although the call mentioned in the above embodiment refers to a call of the telephone, the call may be a multimedia short message or the like, or may be other new telecommunication services that may appear in the future. Thus, it is also possible for services such as the multimedia short message to proceed for a certain period of time, allowing the called user to reject the specific multimedia short message in similar ways. And the calls may also be text short messages, in which case the call numbers and the group codes may be sent to the called terminal via UUS. Thus, the calls may also be UUS, in which case the call numbers and the group codes may be sent to the called terminal via the text short messages or the multimedia short messages.

The present invention can solve the problem of unnecessary telephone calls and unnecessary multimedia short messages, and the call numbers and the group codes can be transmitted to the called terminal via the plain text short messages.

In addition, the short messages or UUS sent by the calling terminal can be identified by distinct marks to send the group codes. That is, a mark such as * # XXXXXX # * YYYYYY may be used to identify a specific group code, where XXXXXX is an identification code and YYYYYY is a group code. For example, when the group code is 135789 and the content of the short message or UUS is * # 000100 # *, 000100 is an identification code of the short message or UUS for transmitting the group code. In an actual embodiment, for the convenience of the user, a group code short message menu may be added in the called terminal. When the user generates a short message through the menu, the called terminal automatically adds the identification code XXXXXX to the short message.

If the short message carries the call number directly, * # XXXXXX # * YYYYYY * NNNNNNNNNNN may be used, where NNNNNNNNNNN is the call number and 000110 is a group code short message for carrying the call number or Can be used to identify UUS.

* # XXXXXX # * YYYYYY * may be used to identify the corresponding deregistration command, and 001100 may be used to identify a group code short message or UUS for deregistration.

The called terminal may determine whether the short message carries a group code according to the existence of * # ?????? # * in the short message. The string consisting of? Means that any character can be used.

The foregoing is merely a more preferred embodiment and is not used to limit within the scope of protection thereby.
