Description

Method for realizing state of user terminal

The present invention relates to the field of user terminal state management in a communication network, and in particular to a method for implementing a state of a user terminal. Background of the invention

Currently, as a new telecommunication network architecture, Next Generation Networks (NGN) are gradually replacing traditional telecommunication networks. Softswitch equipment (also known as media gateway controller), as a key component in NGN, mainly implements functions such as call control and service processing information transmission.

In the NGN, communication between the user terminals is inevitable, but each user terminal cannot know each other's current status, such as: off-hook, idle, ringing, and the like. Therefore, when the user uses the user terminal to call other user terminals, the call often fails because the current state of the user terminal is not known in advance, for example, the user calls the user using the user terminal A without knowing the current state of the user terminal B. Terminal B, but the user terminal B is currently in the off-hook state, which will cause the user to use the user terminal A to make a call failure to the user terminal B.

In practical applications, the above situations often occur, resulting in low quality of NGN providing services to users; affecting user satisfaction. Summary of the invention

After receiving the status message, the subscribing user terminal sends a prompt signal corresponding to the current status of the subscribed user terminal according to the status parameter included in the status message.

The way to set up the subscription relationship is:

Entering, to the softswitch device, the identifier of the subscribing user terminal, the different indicator device number on the subscribing user terminal, and the subscribed user terminal identifier subscribed by the corresponding indication device, and the softswitch device establishes a correspondence between the received content and save.

Methods for setting the status parameters include:

The softswitch device sends a status report command to each user terminal, and the user terminal that receives the command reports the current status of the user terminal to the softswitch device. After receiving the status reported by the user terminal, the softswitch device contacts the user in the state. A correspondence is established between the identifiers of the terminals, and the user terminal identifiers and the user terminal states in which the corresponding relationships are established are stored in the state list as the state parameters.

Methods for setting the status parameters include:

The softswitch device sends a status report command to each user terminal, and the user terminal that receives the command reports the current status of the user to the softswitch device. After receiving the status reported by the user terminal, the softswitch device sets the subscription. Searching for the indication device number corresponding to the identifier of the user terminal in the subscription relationship list of the relationship, and establishing a correspondence relationship between the indication device number and the state of the user terminal, and then establishing the indication device number and the user with the corresponding relationship The terminal status is stored in the status list as the status parameter. The status parameter sent by the softswitch device includes: a current status of the subscribed user terminal and a number of the pointing device that subscribes to the subscribed user terminal on the subscribing user terminal; or an identifier of the subscribed user terminal and the The current status of the subscribed user terminal.

Or the status parameter sent by the softswitch device includes: an identifier of the subscribed user terminal and a current status of the subscribed user terminal; and the method for the subscribing user terminal to send the prompt signal is:

The subscribing user terminal searches for the self-instruction device number corresponding to the identifier included in the status parameter in the pre-stored subscription relationship, and uses the self-indicating device corresponding to the number to issue a corresponding status of the received subscribed user terminal. Prompt signal.

The method for the subscribing user terminal to send the prompting signal by using the indication device is: the subscribing user terminal sends the audio data corresponding to the current state of the subscribing user terminal to the pointing device, and the indicating device receives the audio data. After playing the audio data, the current state of the subscribed user terminal corresponding to the audio data; and/or,

FIG. 3 is a flowchart of a softswitch device updating a user terminal subscription relationship according to the present invention. Mode for carrying out the invention

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

The method for implementing the status of the user terminal provided by the present invention needs to preset the subscription relationship between each user terminal and the status parameter of each user terminal, and the softswitch device learns the subscription corresponding to the subscribed user terminal according to the subscription relationship. a user terminal, and sending a status message including the status parameter of the subscribed user terminal to the subscribing user terminal; after receiving the status message, the subscribing user terminal issues a current status with the subscribed user terminal according to the status parameter included in the status message. Corresponding prompt signal. Moreover, the current state of the subscribed user terminal that has changed the state may be determined by the softswitch device, and the state information including the current state of the subscribed user terminal is sent to the subscribing user terminal; the subscribing user terminal that receives the state information And prompting a prompt signal corresponding to the current state of the subscribed user terminal according to the status information.

It can be seen that the key to the method of the present invention is that: the subscribing user terminal can display the status of the subscribed user terminal to which it subscribes, and the softswitch device learns that the subscribed user terminal status is sent to enable the subscribing user terminal to display the prompt signal. Said that the change has occurred The current status of the subscribed user terminal. The above content is embodied in FIG. 1. FIG. 1 is a flowchart of implementing a state indication function of a user terminal according to a preferred embodiment of the present invention, and the process includes the following steps:

Step 101: Set configuration data of all user terminals in the NGN, 'subscription relationship between each user terminal, and status parameters of each user terminal on the softswitch device.

The operator can apply the user terminal configuration data and the subscription relationship between the user terminals to the softswitch device by using the background management platform of the softswitch device. The softswitch device usually saves the received information in its own database. The softswitch device typically sets the state parameters by actively obtaining the current state of each user terminal, which is typically stored in its own database by the softswitch device.

In the above information, the subscription relationship between the user terminals is usually stored in the form of a subscription relationship list; the current state parameters of each user terminal are usually stored in the form of a state list in which different user terminals are stored. Current different states, such as: idle, off-hook, etc.

The specific state parameter setting mode is generally as follows: The softswitch device sends a status report command to each user terminal in the NGN periodically or in real time, and the user terminal that receives the command reports the current state of the user to the softswitch device. After receiving the state reported by the user terminal, the softswitch device establishes a correspondence between the state and the identifier of the user terminal, and is established in its own state list.

The user terminal configuration data includes: a user terminal identifier, a user terminal internet protocol (IP) address, a port number of the softswitch device and the user terminal, and the like.

Among all user terminals, one user terminal can subscribe to the status of one or more other user terminals, and the status of one user terminal can be subscribed by other one or more user terminals. Each user terminal is provided with an indicator light or a display that can display the current status of other user terminals. Indicator device such as the indicator. For example, it is assumed that in the user terminal, the user terminal B, and the user terminal C, the user terminal A is provided with an indication device that can display the current state of the user terminal B and the user terminal C.

Then, it can be said that the user terminal A subscribes to the state of the user terminal B and the state of the user terminal C, and the state of the user terminal B and the state of the user terminal C are subscribed by the user terminal A. The status cylinder in which the user terminal A is subscribed to the user terminal B is generally referred to as: the user terminal A subscribes to the user terminal B. In contrast, the user terminal A can be referred to as a subscribing user terminal, and the user terminal B and the user terminal C to which the user terminal A is subscribed can be referred to as a subscribing user terminal. Of course, the user terminal B may also subscribe to the user terminal A and the user terminal C.

It can be seen that each user terminal in the NGN may subscribe to other subscribed user terminals as a subscribing user terminal, and each user terminal in the NGN may also be subscribed as a subscribing user terminal by other subscribing user terminals; Both the user terminal and the subscribed user terminal are relatively speaking.

Further, the number of pointing devices set on each user terminal is typically greater than or equal to the number of user terminals subscribed to by the user terminal, and each pointing device on each user terminal typically displays only the status of one subscribed user terminal. For example, when at least two indication devices are provided on the user terminal A, the user terminal A can subscribe to the user terminal B and the user terminal C; a pointing device on the user terminal A is used to display the current state of the user terminal B, on the user terminal A. Another indicator device is used to display the current state of the user terminal C. Of course, if only one pointing device is set on the user terminal A, the user terminal A can only subscribe to the user terminal B or the user terminal C, and the pointing device is used to display the current state of the user terminal B or the user terminal C.

It can be seen from the above that since one subscriber terminal can subscribe to one or more subscribed subscriber terminals, and because different indication devices on the subscriber terminal can display the status of the different subscribed subscriber terminals, it can be considered as: Different fingers on the user terminal The device is subscribed to different subscribed user terminals. Further, a number is set in advance for each pointing device on the user terminal, and a correspondence relationship is established between different pointing devices and different numbers, and the user terminal can obtain the number of one of the pointing devices according to the corresponding relationship. What is it.

It can be seen from the above that the subscription relationship between the user terminals input by the operator to the softswitch device usually appears as follows: the identifier of the subscribing user terminal, the different indicator device number on the subscribing user terminal, and the subscription of the corresponding pointing device. The subscribed user terminal identifier, the softswitch device establishes a correspondence between the received content, and saves the subscribed user terminal identifier, the indication device number, and the subscribed user terminal identifier of the corresponding relationship in its own Subscribe to the list of relationships.

For example, if the pointing device A on the user terminal A subscribes to the user terminal X, the operator inputs the identifier of the user terminal A, the number of the pointing device A, and the identifier of the user terminal X to the softswitch device, and the softswitch device receives the above. A correspondence is established between the content, and the identifier of the user terminal A, the number indicating the device A, and the identifier of the user terminal X, which are associated with each other, are stored in the subscription relationship list of the user terminal.

In addition, for the operation of the softswitch device to set the state parameter, when the softswitch device receives the state reported by the user terminal, the softswitch device may further search for the user terminal in the subscription relationship list. Identifying the corresponding pointing device number, establishing a correspondence between the indicating device number and the state of the user terminal, and storing the indicating device number and the user terminal state in which the corresponding relationship is established as the state parameter in itself In the status list.

That is to say, the status parameter may be the user terminal identifier and the user terminal status, or may be the indication device number and the user terminal status.

Step 102: After the user terminal is powered on or restarted, the user terminal sends a registration request to the softswitch device, where the request includes the user terminal identifier, the user terminal IP address, and the like. According to.

Step 103: After receiving the registration request from the user, the softswitch device determines whether the user terminal is a legitimate user terminal according to the user terminal configuration data included in the request. The method of judging is: the softswitch device reads the user terminal configuration data included in the registration request, and determines whether the configuration data of the user terminal can match the corresponding configuration data of a user terminal stored by itself, if The softswitch device is configured with the configuration data of the user terminal, and the softswitch device can provide the service for the user terminal. In this case, the softswitch device determines that the user terminal is a legitimate user terminal; The configuration data of the user terminal is not configured in the switching device, and the softswitch device cannot provide the user terminal. In this case, the softswitch device determines that the user terminal is not a legal user terminal.

Step 104: After the softswitch device completes the determining, the response is sent to the user terminal according to the judgment result. If the softswitch device determines that the user terminal is not a legal user terminal, the softswitch device sends a registration failure response to the user terminal, and ends the process; if the softswitch device determines that the user terminal is a legitimate user terminal, the softswitch The device sends a registration success response to the user terminal, and proceeds to step 105.

Step 105: The softswitch device searches the subscription relationship list saved by itself to find out which user terminals (also referred to as subscribed user terminals) that the user terminal (also referred to as a subscribed user terminal) subscribe to, and finds the subscribed user terminal. The subscription relationship with the subscribed user terminal is sent to the subscribing user terminal; at the same time, the softswitch device also sends a status message containing the current status of the subscribing user terminal to the subscribing user terminal.

The subscription relationship sent by the softswitch device is generally: an identifier of the subscribing user terminal, a different indicator device number on the subscribing user terminal, and a subscribing user terminal identifier subscribed by the corresponding indication device.

The status message includes the current status of the subscribed user terminal and the subscription user end Indicates the number of the device on the side; or contains the current status of the subscribed user terminal and the identity of the subscribed user terminal.

The subscription relationship and the status message may be sent separately, or may be included in the registration success response.

Step 106: After receiving the subscription relationship and the status message from the softswitch device, the subscription user terminal saves the subscription relationship and the current status of the subscribed user terminal included in the status message; and, the subscription The pointing device of the user terminal application itself displays the current state of the subscribed user terminal.

The subscription relationship and the current state of the subscribed user terminal are typically stored in a data storage device such as a hard disk of the subscribing user terminal.

The subscription user terminal usually stores the current state of the subscribed user terminal in the form of a status list. The storage mode of the specific status of the subscribed user terminal is usually: the number of the pointing device on the subscribing user terminal, and the subscribing user terminal And storing the current status and the corresponding indicator device number in the status list of the user terminal; if the status message includes the current status of the subscribed user terminal and the identifier of the corresponding subscribed user terminal, The subscribing user terminal stores the current status and the corresponding subscribed user terminal identifier in its own status list.

The subscribing user terminal typically stores the received subscription relationship in the form of a subscription relationship list. The specific operation is: the subscribing user terminal stores the subscription user terminal identifier, the indication device number, and the subscribed user terminal identifier included in the subscription relationship stored in the subscription relationship list.

Further, the subscribing user terminal receiving the subscription relationship displays the current status of the subscribed user terminal subscribed by the corresponding indication device by using its own different pointing device. The specific operation is: if the status message includes the current status of the subscribed user terminal and the subscribed user The number of the device is indicated on the terminal, and the subscribing user terminal receiving the status message sends a prompt signal corresponding to the received current status of the subscribed user terminal by using the self-indicating device corresponding to the indication device number. The identifier of the user terminal, the subscribing user terminal that receives the status message searches for the self-instruction device number corresponding to the identifier in the subscription relationship list stored by itself, and uses the number to indicate the signal.

The indicating device displays various ways of subscribing to the current state of the user terminal, such as: emitting a voice, displaying a subtitle, or emitting a brightness and/or a different blinking frequency. The user terminal can display the current status of the subscribed user terminal by applying one or more of the above display modes.

For the manner of displaying the voice, the subscribing user terminal sends the audio data corresponding to the current state of the subscribed user terminal to the pointing device, and the indicating device receives the audio data and then plays the audio data corresponding to the audio data. Subscribing to the current state of the user terminal; for displaying the display mode of the subtitle, the subscribing user terminal sends the video data corresponding to the current state of the subscribing user terminal to the pointing device, and the pointing device displays the video data and then plays the image in an image manner. The current state of the subscribed user terminal corresponding to the video data; for displaying the bright display mode, the subscribing user terminal sends a level signal corresponding to the current state of the subscribed user terminal to the pointing device, and the indicating device sends out The brightness of the brightness and/or the flicker frequency corresponding to the received level signal. Of course, the user needs to know in advance which of the states of the subscriber terminal to which the brightness and/or the blinking frequency are different.

Step 107: After the subscription user terminal saves the subscription relationship from the softswitch device and the status message, sends an acknowledgement response to the softswitch device to notify the softswitch device of the subscription relationship and the status message has been Received successfully.

As can be seen from the above, the operations in steps 101 to 107 are for achieving the object of the present invention. The technical basis is laid, that is, the subscription relationship between each user terminal and the status of each user terminal are stored in the softswitch device, and the status of each user terminal subscribed to the user terminal is notified. Only when such a technical basis exists can the subscription user terminal in the NGN be able to display its current status of the subscribed user terminal by using its own pointing device.

In the foregoing implementation process, the subscription relationship and the status parameter acquired by each user terminal are obtained from a status message sent by the softswitch device. Of course, the user terminal can also obtain the subscription relationship and the status parameter through a pre-configured method.

Step 108: After the softswitch device stores the subscription relationship between each user terminal and the state of each user terminal, and the state of the user terminal that each user terminal subscribes to in the user terminal, the state of the user terminal may change, such as : Change from idle state to off-hook state, from ringing state to idle state, and so on.

When the state change occurs in the user terminal, the softswitch device can know in time that the user terminal has changed state, and determine the current state of the user terminal where the state change occurs.

There are two methods for the softswitch device to determine the current state of the user terminal in which the state change occurs. The first method is: each user terminal in the NGN triggers an event due to the state change when the state changes itself. Report the event to the softswitch device. The softswitch device searches for the state of the user terminal corresponding to the event in the event state corresponding list stored in the device, and determines the state of the user terminal as the current state after the state change of the user terminal. The event status correspondence list usually stores an event and a status of the user terminal corresponding to the event.

For example, the user terminal reports the fork event to the softswitch device because the user is hanged up. After receiving the flash event, the softswitch device finds that the user terminal corresponding to the flash event is idle in the event status corresponding list. The state, thus determining that the current state of the user terminal after the state change is an idle state.

The second method is: The softswitch device periodically or realizes to each user terminal in the NGN. The status report is sent periodically, and the user terminal that receives the command reports its current status to the softswitch. After receiving the status reported by the user terminal, the softswitch device searches for the status of the user terminal corresponding to the corresponding user terminal identifier stored in the user terminal corresponding status list stored in the user terminal, and determines the status of the stored user terminal. If the status of the received user terminal is the same, if the same, the softswitch device considers that the state of the user terminal does not change, and does not process the received state of the user terminal; if not, the softswitch device It is considered that the state of the user terminal has changed, and the received state of the user terminal is determined as the current state after the state change of the user terminal occurs. The status of the terminal.

The softswitch device usually overwrites the state of the originally stored user terminal with the current state of the user terminal in which the state change occurs after learning that the user terminal has changed state.

Step 109: After determining the current state of the user terminal in which the state change occurs, the softswitch device sends the state information including the current state of the user terminal to the user terminal that subscribes to the user terminal. At this time, since there is a subscription relationship between the user terminals, the status information including the current status of the subscribed user terminal can be sent to the subscribing user terminal.

The specific method is: the softswitch device searches for the number of the pointing device on the subscribing user terminal corresponding to the subscribing user terminal identifier in the subscription relationship list, and the user terminal to which the pointing device belongs is the subscribing user terminal, and the subscription user The terminal sends status information. The status information includes: a current status of the subscribed user terminal after the status change and a number of the pointing device on the subscribing user terminal.

In an actual application, the number of the pointing device on the subscribing user terminal included in the status information sent by the softswitch device may be replaced by the identifier of the subscribed user terminal. In this way, the status information includes the status of the subscribed user terminal after the status change. The pre-state and the identity of the subscribed user terminal.

Step 110: After receiving the status information from the softswitch device, the subscription user terminal updates the status of the corresponding user terminal stored by the subscribed user terminal included in the status information, and sends and receives the status of the corresponding user terminal. The prompt signal corresponding to the current state of the subscribed user terminal.

The method for the subscribing user terminal to update the state of the user terminal stored by the subscribing user terminal is generally: if the status information received by the subscribing user terminal includes the current state of the subscribed user terminal state change and the subscribing user The device number is indicated on the terminal, and the subscribing user terminal uses the received current state to overwrite the state of the subscribed user terminal corresponding to the indication device number originally stored in the self-status list.

If the status information received by the subscribing user terminal includes the current status of the subscribed user terminal status change and the identifier of the subscribed user terminal, the subscribing user terminal searches for the subscribed user in its own subscription relationship list. The number of the self-indicating device corresponding to the terminal identifier is used, and the state of the subscribed user terminal corresponding to the indicating component number originally stored in the self-status list is overwritten by the received current state.

For the operation of the subscribing user terminal to send the prompting signal, if the status information received by the subscribing user terminal includes the current status of the changed status of the subscribing user terminal, and the subscribing user terminal Indicates the number of the device, and the subscribing user terminal displays the current state by using the self-indicating device corresponding to the number.

If the status information received by the subscribing user terminal includes the current status of the subscribed user terminal status change and the identifier of the subscribed user terminal, the subscribing user terminal searches for the subscription status list in the subscription status The number of the self-indicating device corresponding to the user terminal identifier is subscribed, and the self-indicating device corresponding to the number is used to display the current state.

The indicating device displays various ways of being subscribed to the current state of the user terminal, such as: Voice out, subtitles, or brightness that emits different brightness and/or blinking frequencies. The specific display mode is the same as the corresponding display mode described in step 106.

Step 111: After the subscribed user terminal finishes updating the status of the subscribed user terminal stored by itself, sending a status update confirmation response to the softswitch device, so that the softswitch device learns that the subscription user terminal has completed the update operation. .

In a practical application, if the softswitch device applies the second party in step 108, the softswitch device may further send the state of the user terminal to a subscribing user terminal that subscribes to the state of the user terminal, the subscribing user terminal. Then, the state of the corresponding user terminal stored by itself is updated with the received state of the user terminal, and a prompt signal corresponding to the received state of the user terminal is also sent.

The method for the subscriber terminal to update the state of the user terminal stored in the same manner as the corresponding update method in step 110, the method for the subscriber terminal to issue the prompting signal, and the subscriber terminal in step 110 to send a prompt signal The corresponding method is the same.

It can be seen from the above that in order to implement the state indication function of the user terminal embodied in step 108 to step 111 in Fig. 1, the implementation method can be generally applied:

Pre-setting the subscription relationship between each user terminal and the configuration data of each user terminal state. The information may be set in the softswitch device or in the third-party device. As long as the softswitch device needs the information, the information can be obtained. can. a status, and sending status information including the current status of the subscribed user terminal to the subscribing user terminal; thereafter, the subscribing user terminal receiving the status information, according to the status information, is sent according to the current status of the received subscribing user terminal. Corresponding prompt signal.

As can be seen from the above, the flow shown in FIG. 1 implements the function of the status indication of the user terminal. When the status of the subscribing user terminal changes, the subscribing user terminal can display the current status of the changed status of the subscribing user terminal in time, so that the user can determine whether to call according to the current status of the subscribing user terminal displayed by the subscribing user terminal. The subscribed user terminal. It can be seen that the service quality of NGN has been significantly improved, so user satisfaction will also be significantly improved.

In practical applications, the subscription relationship between the user terminals is not static, and the subscription relationship between the user terminals can be changed by setting on the user terminal or the softswitch device.

Next, how to change the subscription relationship between user terminals by setting on the user terminal will be described first. Referring to FIG. 2, FIG. 2 is a flowchart of updating a self-subscription relationship of a user terminal according to the present invention, where the process includes the following steps:

Step 201: The user can update the subscription relationship between the user terminal and the subscribed user terminal subscribed to by the user terminal by inputting the subscription relationship to be updated to the user terminal. The update operation may be performed in various manners, such as : Add one or more update methods, such as adding a new subscription relationship, modifying a previously stored subscription relationship, or deleting a previously stored subscription relationship.

When the user inputs the modified subscription relationship to the user terminal, the user terminal updates the corresponding subscription relationship stored by the user according to the received subscription relationship. For example, the pointing device A on the user terminal A originally subscribed to the user terminal X, and now the user wants to modify the subscription relationship to the pointing device A on the user terminal A to subscribe to the user terminal Y. Then, the user inputs a modification command including the number indicating the device A and the identification of the user terminal Y to the user terminal A. After receiving the command, the user terminal modifies the identifier of the user terminal X corresponding to the number indicating the device A in the self-subscription relationship list to the identifier of the user terminal Y.

When the user inputs a newly added subscription relationship to the user terminal, the user terminal stores the received subscription relationship in its own subscription relationship list. When the user inputs the deleted subscription relationship to the user terminal, the user terminal searches for the subscription relationship stored by itself and deletes it. For example, the user inputs a deletion command including the number indicating the device A and the identifier of the user terminal Y to the user terminal A. After receiving the command, the user terminal A subscribes to the number of the pointing device A that has the corresponding relationship stored in the subscription relationship list. The identifier with the user terminal Y is deleted.

Step 202: After the user terminal completes the foregoing update operation, send the subscription relationship to be updated by the user to the softswitch device, for example, the user terminal adds the modified subscription relationship entered by the user, newly added. The subscription relationship and/or the deleted subscription relationship are sent to the softswitch device.

Step 203: After receiving the subscription relationship to be updated, the softswitch device performs data validity check on the subscription relationship to be updated, for example, determining whether the user terminal has successfully registered on the softswitch device, and the user terminal Whether the number of subscribed user terminals subscribed exceeds the allowable value set in advance, and the like.

Step 204: If the softswitch device confirms that the subscription relationship to be updated is valid, the softswitch device sends a check result of the confirmation update for the subscription relationship to the user terminal; and the softswitch device further updates the saved account according to the subscription relationship. The corresponding subscription relationship, for example, the softswitch device overwrites the identifier of the user terminal X corresponding to the number of the pointing device A of the user terminal A in the self-subscription relationship list by the identifier of the user terminal Y.

If the softswitch device confirms that the subscription relationship to be updated is invalid, the softswitch device sends a check result to the user terminal for the subscription relationship update failure. After receiving the check result, the user terminal restores the subscription relationship stored by itself to the subscription relationship between the update operations. It can be seen that, in order to ensure that the user terminal can restore the subscription relationship, in step 201, before the user terminal performs the update operation, a subscription relationship that does not perform an update operation is additionally saved. In this way, the user terminal can update the saved subscription relationship with the update operation after receiving the check result of the update failure. Complete the appropriate subscription relationship for the update operation.

From a technical point of view, since the user terminal has performed the update operation in step 201, if the user terminal performs the restoring operation in step 204, the operation complexity of the user terminal is increased, so that the user terminal The maintenance difficulty and cost of the user terminal increase. Therefore, in step 201, when the user inputs the subscription relationship to be updated to the user terminal, the user terminal first saves the subscription relationship to be updated and proceeds to step 202 without performing the update operation. In step 204, if the user terminal receives the check result from the softswitch device confirmation update, the user terminal updates the corresponding subscription relationship stored by itself according to the subscription relationship for the check result; if the user terminal receives the check result from The result of the check of the failure of the softswitch device update, the user terminal deletes the additionally saved subscription relationship for which the check result is directed.

Next, describe how to change the subscription relationship between user terminals by setting them on the softswitch device. Referring to FIG. 3, FIG. 3 is a flowchart of a softswitch device updating a user terminal subscription relationship according to the present invention, where the process includes the following steps:

Step 301: The operator can apply the softswitch device's background management platform to input the subscription relationship to be updated to the softswitch device, and update the softswitch device to store the subscribed user terminal update operation in various manners, such as: adding a new subscription One or more update methods, such as revising a previously stored subscription relationship or deleting a previously stored subscription relationship.

When the operator inputs the modified subscription relationship to the softswitch device, the softswitch device updates the corresponding subscription relationship stored by itself according to the received subscription relationship. For example, the indication device A on the user terminal A stored in the softswitch device originally subscribed to the user terminal X, and now receives the modification command including the identifier of the user terminal A, the number indicating the device A, and the identifier of the user terminal Y, and the softswitch. The device overwrites the identifier of the user terminal X corresponding to the number of the pointing device A of the user terminal A in the self-subscription relationship list by the identifier of the user terminal Y. When the operator inputs a newly added subscription relationship to the softswitch device, the softswitch device stores the received subscription relationship in its own subscription relationship list.

When the operator enters the deleted subscription relationship to the softswitch device, the softswitch device looks up the subscription relationship stored by itself and deletes it. For example, the operator inputs a deletion command including the number indicating the device A and the identifier of the user terminal Y to the softswitch device. After receiving the command, the softswitch device will subscribe to the indicator A of the relationship established in the subscription relationship list. The number is deleted from the ID of the user terminal Y.

After the softswitch device completes the above update operation, the data validity check is performed on the updated subscription relationship, such as: determining whether the user terminal has been registered on the softswitch device, and whether the number of subscribed user terminals subscribed by the user terminal exceeds Pre-set allowable values, etc.

Step 302: If the softswitch device confirms that the updated subscription relationship is invalid, the softswitch device issues an error prompt for the subscription relationship, and the operator needs to restore the subscription relationship corresponding to the prompt to perform the update operation. Subscription relationship; if the softswitch device confirms that the updated subscription relationship is valid, the softswitch device sends the subscription relationship to the subscribing user terminal in the subscription relationship.

It can be seen that, in order to ensure that the subscription relationship can be restored, in step 301, before the update operation, a subscription relationship that does not perform an update operation is additionally saved. In this way, after the softswitch device issues the error prompt, the corresponding subscription relationship of the completed update operation is updated with the saved subscription relationship of the update operation.

Step 303: After receiving the subscription relationship from the softswitch device, the subscription user terminal updates the corresponding subscription relationship saved by itself according to the subscription relationship, and the manner of the specific update operation is corresponding to the softswitch device in step 301. The update operation is done in the same way. Step 304: After completing the update operation, the subscribing user terminal sends an acknowledgment response to the softswitch device to notify the softswitch device that the subscribing user terminal completes the update operation. In an actual application, the softswitch device may not perform the update operation in step 301, but separately save the subscription relationship that is input by the operator to be updated. After the data validity check is completed, the softswitch device performs the update operation in step 301 according to the subscription relationship, and the subscription is invalid for the data validity check result. Relationship, the softswitch device deletes the additionally saved subscription relationship.

The communication interaction between the softswitch device and the user terminal is carried by the communication protocol applied in the current NGN, for example, by the Media Gateway Control Protocol (MGCP), or by the H.248 protocol.

It can be seen from the above that the method provided by the present invention implements the function of the status indication of the user terminal, and the subscribing user terminal can display the status of the subscribing user terminal to which it subscribes; and when the status of the subscribing user terminal changes When the subscriber terminal is able to display the current state of the subscribed user terminal in a state change, the user can determine whether to call the subscribed user terminal according to the current state of the subscribed user terminal displayed by the subscriber terminal; The subscription relationship between the user terminals can also be changed by setting on the user terminal or the softswitch device. It can be seen that the service quality of NGN has been significantly improved, so user satisfaction will also be significantly improved.
