Detailed Description
The invention will be further illustrated with reference to specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and such equivalents may fall within the scope of the present invention as defined in the appended claims.
Referring to fig. 1, the present invention discloses a call disturbance-free processing system based on signaling monitoring. As shown in the figure, a preferred embodiment of it is arranged in a communication ims (ip Multimedia sybsystem) network, consisting of a do-not-disturb application server 101, a home subscriber server 104, a call session control function network element 102, a calling session border controller 107, a called session border controller 105 and a service platform 103. The communication ims (ip Multimedia sybsystem) network is used to carry the processing of the speech path between the called user 106 and the calling user 108, the monitoring of signaling, and the triggering control of user services.
The service platform 103 comprises a signing logout management module and a rule setting management module. The signing logout management module provides an interface for signing and logout of the user, and is used for accepting signing/logout disturbance-free service of the user and updating signing information (including signing or logout information). The subscription information of the user do not disturb the service is then sent to the home subscriber server 104 for storage. And the rule setting management module provides a user-defined rule setting interface for setting the disturbance-free rule corresponding to the disturbance-free service. After the user completes the setup of the do-not-disturb rule, the user is responsible for issuing and synchronizing the data of the user-defined do-not-disturb rule to the do-not-disturb application server 101, and the data is stored by the do-not-disturb application server 101.
The calling session border controller 107 is configured to transmit call information initiated by the calling subscriber 108 to the call session control function network element 102 in which the called session border controller 105 is located. Called session border controller 105 is then used to turn on called user 106.
When the calling speech path arrives, the call session control function network element 102 selectively triggers the call speech path to the do-not-disturb application server 101 according to the user do-not-disturb service subscription data stored in the home subscriber server 104. Specifically, the network element 102 with a call session control function acquires the subscription information of the called user 106 from the home subscriber server 104, then triggers the voice channel of the subscribed user to the do-not-disturb application server 101, and performs voice channel processing operations such as reject, forward, continue, and the like on the voice channel according to the determination result of the do-not-disturb application server 101, or directly triggers the voice channel of the non-subscribed user to the called session boundary controller 105 for connecting the called user 106.
Do not disturb application server 101 saves the user configured do not disturb rule. The no-disturbance rule comprises a matching condition and a speech path processing mode. The matching conditions include a time range condition, a period attribute condition, and a number range condition, and their respective logical combinations. The time range condition is used to specify a time range in which the do-not-disturb rule is effective, including a do-not-disturb start time and a do-not-disturb end time. The period attribute condition is used to specify a repeating period for which the do-not-disturb rule is to take effect, including single, daily, weekday, non-weekday, and specified date. The number range condition is used for designating a calling number range corresponding to the effective non-disturbing rule, and the calling number range includes all numbers, mobile phone numbers, non-mobile phone numbers, individual numbers and a number list. For example, a non-workday 8: 00 to 20: 00 is the condition for the do not disturb rule to take effect (and operation of time range condition and period attribute condition), and it is also possible to choose 18: 00-7: 00 and all non-mobile phone numbers are the conditions (time range conditions and period attribute conditions and operations, and then number range conditions or operations) for the no-disturb rule to take effect. The speech path processing modes comprise refusing, transferring and continuing.
The do-not-disturb application server 101 is configured to extract relevant information from the received speech path (Invite information), match conditions from the previously stored do-not-disturb rule, and then feed back a speech path processing mode of the speech path to the call session control function network element 102. Then, the network element 102 with call session control function processes the session according to the obtained session processing mode, i.e. refusing to connect, transferring and continuing to connect.
Referring to fig. 2, the present invention further discloses a call disturbance-free processing method based on signaling monitoring, which uses the call disturbance-free processing system based on signaling monitoring to complete the work. As shown, a preferred embodiment thereof comprises the steps of:
step S201, the no-disturbance service is applied for opening by the called party. The service platform accepts a user disturbance-free service opening request, and the called user updates subscription information through a subscription logout management module.
Step S202, the subscription information is sent to the home subscriber server and then stored, and the non-disturbing service takes effect at the moment. The called user further sets the disturbance-free rule through the rule setting management module, and then the disturbance-free rule is sent to the disturbance-free application server for storage.
The no-disturb rule includes two major parts, the first part is used to select the matching conditions of the rule, including the time range condition, the period attribute condition and the number range condition, and the logical combination of these conditions. The second part is a speech path processing mode of how to further process the speech path of the calling party by feeding back the selected rule to the call session control function network element, and the method comprises the following steps: refusing to connect, switching (the user needs to configure the switching number), or continuing to connect.
Step S203, after the call information reaches the call session control function network element where the called session border controller is located through the calling session border controller, the call session control function network element first reads the subscription information of the called user from the home subscriber server. If the called user signs up the do-not-disturb service and the service is valid, the voice channel is triggered to the do-not-disturb application server, and the step S204 is entered. If the user has not signed up for the do-not-disturb service or the service is not valid, the do-not-disturb application server is bypassed and the process goes to step S207.
Step S204, after receiving the voice channel triggered by the call session control function network element, the disturbance-free application server firstly extracts the called party number and the corresponding voice channel information (current time, current date, calling number, etc.) from the Invite message of the calling party voice channel, then searches the disturbance-free rule preset by the called party by using the called party number, finally traverses all the disturbance-free rules of the user, and performs condition matching on the voice channel information extracted from the voice channel according to the matching condition in each disturbance-free rule.
And when the conditions are matched, the disturbance-free application server performs matching according to the time range conditions, the period attribute conditions, the number range conditions and the logic combination thereof, and selects the hit rules. Specifically, the do-not-disturb application server firstly matches a time range condition, namely, judges whether the current time is in an effective time range of the user-defined do-not-disturb rule (the call time is between the do-not-disturb starting time and the do-not-disturb ending time), secondly matches a period attribute condition, namely, judges whether the current date is in an effective time range of the period attribute of the user-defined do-not-disturb rule (the current date meets the date in the period attribute condition, the period attribute condition comprises single time, every day, every working day, non-working day and appointed date), and then matches a number range condition, namely, judges whether the calling number is in a number range of the user-defined do-not-disturb rule (the number range comprises all numbers, mobile phone numbers, non-mobile phone numbers, single numbers and number lists).
Step S205 determines whether there is a no-disturb rule hit. When the matching condition contained in the disturbance-free rule is consistent with the information extracted from the speech path, the disturbance-free rule is hit. If yes, the do-not-disturb application server feeds back the speech path processing mode in the do-not-disturb rule to the call session control function network element, and step S206 is entered, otherwise step S207 is entered.
And step S206, the call session control function network element processes the speech path according to the speech path processing mode obtained by feedback, and the service is finished after the processing is finished. The treatment process specifically comprises the following steps:
when the processing mode of the speech path in the hit rule is refusing, the call session control function network element sends hang-up information to the calling party (calling user) through the calling session boundary controller.
When the speech path processing mode in the hit rule is forwarding, the call session control function network element forwards the call to a forwarding number contained in the forwarding mode.
When the processing mode of the speech path in the hit rule is continuous connection, the call session control function network element connects the called party (called user) through the called session boundary controller.
Step S207, the call session control function network element directly triggers the speech path to the called session boundary controller, and the called session boundary controller connects the called user.
In addition, the service platform also accepts a user disturbance-free service logout request, and the user updates the subscription information through the subscription logout management module to log out the disturbance-free service. After the signing information containing the logout information is issued to the home subscriber server, the home subscriber server deletes the original signing information of the user. After the call comes, the session control function network element considers that the user is not a signed user, so that a speech path is not triggered to the disturbance-free application server, and the disturbance-free service fails. And simultaneously, the disturbance-free application server deletes the disturbance-free rule of the corresponding user.
Referring to fig. 3, in a preferred embodiment of a call do-not-disturb processing method based on signaling monitoring according to the present invention, in a subscription do-not-disturb service and an application do-not-disturb service, a signaling interaction process includes the following steps:
step S301, in the signing stage, the called user sends the information for applying for signing the disturbance-free service to the service platform through the called session boundary controller.
Step S302, the service platform accepts the subscription application of the user disturbance-free service, and then issues the subscription information to the home subscriber server in the IMS network to which the user belongs, thereby completing the subscription of the disturbance-free service.
Step S303, the call session control function network element in the IMS network to which the called user belongs obtains the user subscription information by inquiring from the home subscriber server.
Step S304, the calling user initiates a call, and the calling session Invite message reaches the call session control function network element in the IMS network to which the called user belongs.
Step S305, the call session control function network element in the IMS network to which the called user belongs triggers the voice channel to the disturbance-free application server in the form of INVITE information.
And step S306, the disturbance-free application server judges according to the preset disturbance-free rule data of the called user, and selects a speech path processing mode corresponding to the hit rule.
Step S307, when the speech path processing mode defined by the hit rule is reject, the disturbance-free application server informs the call session control function network element of performing disconnection operation on the speech path (sending BYE information to the calling subscriber) in a BYE information mode, so that the disturbance-free function is realized under the condition that the subscriber terminal is not aware.
Step S308, when the call path processing mode defined by the hit rule is switching or continuing switching, the disturbance-free application server does not affect the call path switching, and informs the call session control function network element to continue to switch the called user normally or switch to the switching number (send the INVITE information to the called user or the switching number) in the mode of the INVITE information, so as to achieve the function of normally receiving the call within the user-defined permission range. The called user or the subsequent operation of the continuing number follows the signaling flow of the conventional voice call, for example, the called user sends RINGING information to the calling user through the call session control function network element.
The invention provides a call disturbance-free processing system based on signaling monitoring and capable of customizing rules by users, which can realize the call disturbance-free function by adding a special disturbance-free application server in a communication IMS network without adding a special processing module, software and application to a user communication terminal and by pre-customizing the application of the disturbance-free rules by the users stored in the call processing system under the condition that a call speech path does not touch the user terminal.
The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
