In the session border controller shown in fig. 1, the network interface 1003 is mainly used for data communication with other devices; the processor 1001 calls the session control program of the session system stored in the memory 1004 and executes the session control method of the session system provided by the embodiment of the present invention.
The embodiment of the invention provides a session control method of a session system, which is applied to the session system.
Referring to fig. 2, an embodiment of a session control method of the session system of the present application is provided. In this embodiment, the session system includes a first session border controller and a second session border controller, and the method includes:
a step S10 of processing current first session data by the first session border controller and by the second session border controller;
the session Border controller is an sbc (session Border controller), is an IP service gateway in VoIP communication, and is applied to an operator IMS and an enterprise VoIP. The session border controller is deployed at a key node of the VoIP communication network, analyzes and processes data at two ends of the node, and realizes services such as signaling intercommunication, flow control, NAT traversal, call encryption and decryption, illegal access interception, quality of service (QoS) and the like in VoIP services.
The session data is data interactively transmitted by two parties in the session process, for example, voice data of the session. The session data sent by any one party can be sent to the other party of the session only after passing through the session border controller. The two ends of the session border controller may be connected to different types of networks, and the session border controller serves as a node to process various data transmitted from the networks at the two ends of the node and send the data to the other end, so as to realize information transmission and intercommunication between the networks at the two ends.
In a session, the session border controller is used as an intermediate link between a calling party and a called party, from the initiation of a session invitation to the hanging up of the session, and the session border controller controls the proceeding of the session of the two parties and transmits session related data so as to ensure that the terminals of the two parties of the session can smoothly communicate in real time through the session. Further, the session is VoIP, which is a session for performing communication based on the internet unlike a conventional communication network phone.
In other embodiments, the session data may be processed simultaneously by a greater number of session border controllers, e.g., three, four, etc. In this embodiment, the first session border controller and the second session border controller are characterized by processing session data through more than one session border controller.
Step S20, monitoring the operation status of the first session border controller by the second session border controller;
the first session border controller is connected with the second session border controller in a wireless connection or a wired connection mode, and the second session border controller monitors the running state of the first session border controller through the connection with the first session border controller, so that corresponding processing can be performed when the running state of the first session border controller is abnormal, and the second session border controller is controlled manually without waiting for the discovery of a worker.
Further, the monitoring mode may be monitoring through Keepalived application software, which monitors a condition that the server is down or works in a failure. In other embodiments, the operating state of the first session border controller may also be monitored by establishing a heartbeat mechanism, where the heartbeat mechanism is implemented by the first session border controller sending preset information to the second session border controller every other preset time, the second session border controller determining that the first session border controller normally operates according to the received preset information, and when the first session border controller is down or fails to send the preset information, the second session border controller may determine that the operating state of the first session border controller is abnormal if the second session border controller does not receive the preset information beyond the preset time.
In other embodiments, a plurality of session border controllers may be included, and each session border controller may monitor the operating status of the other session border controllers, so that corresponding processing may be performed when any of the session border controllers is abnormal in operating status.
Step S30, processing the current second session data by the second session border controller when the operation state is abnormal shutdown.
And when the second session boundary controller monitors that the running state of the first session boundary controller is abnormal shutdown, taking over to process the current second session data processing work so as to ensure that the current communication service can be continuously carried out.
It should be noted that the second session data represents session data when the operation state of the first session border controller is in the abnormal shutdown condition, and the first session data represents session data when the operation state of the first session border controller is in the normal condition, which is used for distinguishing session data that needs to be processed in the two conditions.
In other embodiments, a plurality of session border controllers may be included, with a first session border controller also being one of the session border controllers, and when the first session border controller becomes abnormally down, the remaining ones of the still functioning session border controllers may process the current second session data.
The embodiment of the invention provides a session control method of a session system, which comprises a first session border controller and a second session border controller, wherein the method comprises the steps of processing current first session data through the first session border controller and the second session border controller, simultaneously processing the session data by utilizing two devices to share load pressure, monitoring the running state of the first session border controller through the second session border controller in the process, and processing the current second session data through the second session border controller when the running state of the first session border controller is monitored to be abnormal shutdown. The second session boundary controller is used for monitoring the running state of the first session boundary controller, the first session boundary controller is timely taken over when the first session boundary controller is abnormally stopped, and the current second session data is continuously processed, so that a user can continuously keep control over a session, the influence of communication service caused by equipment shutdown is reduced, and the use experience of the communication function of the user is improved.
Further, based on the above embodiment, another embodiment of the session control method of the session system of the present application is provided. In this embodiment, the first session data includes first media data and first signaling data, the first media data includes first sub-data and second sub-data, and the second session data includes second media data and second signaling data. Based on this, with reference to fig. 3, the method comprises:
step S11, processing the first sub-data and the first signaling data through the first session boundary controller, and processing the second sub-data through the second session boundary controller;
the signaling data is an instruction for controlling in communication, and can guide terminals, switching systems and transmission systems involved in communication to cooperatively operate, and is used for controlling the connection of channels of sessions and transmitting management information.
The media data is data used for transmitting communication contents in communication, and in a session, the media data includes voice data of the session, and the voice data is transmitted by adopting streaming transmission to form a media stream between the terminal and the session boundary controller. In this embodiment, the first media data is allocated as first sub-data and second sub-data, and the first sub-data and the second sub-data are processed by the first session border controller and the second session border controller, respectively.
In addition, the signaling data is data for managing and controlling session connection, and the media data is content data of the session, so the signaling data and the media data have an associated relationship based on the session. It should be noted that, in this embodiment, the signaling data and the media data of the same session can be processed by different session border controllers, respectively, which does not affect the normal operation of the session. However, the media data of the same session needs to be processed by the same session boundary controller to ensure normal transmission of the media stream, so the media data of the same session is not allocated as the first sub-data and the second sub-data, but only allocated as the first sub-data or the second sub-data.
Further, the session border controller includes a signaling processing module and a media processing module, in this embodiment, a signaling processing module of the first session border controller processes first signaling data in current first session data, and media processing modules of the first session border controller and the second session border controller process first media data in current first session data, where first sub-data in the first media data is processed by the first session border controller, and second sub-data is processed by the second session border controller.
Optionally, the first session border controller receives first signaling data, and processes the first signaling data through a first signaling processing module (a signaling processing module of the first session border controller), for example, the signaling data is set as a signaling for establishing a session request, two terminals to establish a session are determined according to a processing result of the signaling data, the processed signaling data is sent to a called terminal, and a session between the two terminals is established; further, the media data of the session is received, the media data of the session is determined to be the first subdata or the second subdata through the first signaling processing module, for example, the media data of the session is set to be the second subdata, the media data is sent to the second session border controller through the first session border controller, the media data is processed through the media processing module of the second session border controller, and the processed media data is sent to the target terminal. Furthermore, during the ongoing session, real-time signaling data and/or media data are continuously processed by the session border controller.
In other embodiments, the second session border controller may also process the first signaling data, and the two session border controllers cooperatively process the signaling data; or, the session border controller includes more than two devices, and the media data can be distributed into more sub-data to be processed by all the session border controllers in the system respectively.
The media data has larger data volume relative to the signaling data, larger burden is caused to equipment, the pressure during processing the media data can be shared by simultaneously processing the media data through the first session boundary controller and the second session boundary controller, the fault risk of the session boundary controller is reduced, and the use experience of the communication function of a user is improved.
Step S21, sending the first signaling data to the second session border controller through the first session border controller; backing up the received first signaling data by the second session border controller;
it should be noted that the purpose of the second session border controller backing up the received first signaling data is to synchronize the signaling data processed by the first session border controller in real time, so that the second session border controller can take over the work of the first session border controller at any time.
Optionally, when the first session border controller receives the first signaling data and processes the signaling data, the first session border controller synchronizes the signaling data to the second session border controller, and after the signaling data is processed, the second session border controller can also confirm that the signaling data is processed. Thus, the data synchronized by the first session border controller to the second session border controller includes, in addition to the first signaling data, a completion of the processing of the first signaling data by the first session border controller.
In other embodiments, a plurality of session border controllers may be included, wherein the first signaling data processed by a first session border controller may be synchronized to all other session border controllers.
By backing up the first signaling data to the second session boundary controller, the signaling data can be ensured not to be lost when the running state of the first session boundary controller is abnormal, so that the ongoing communication service is correspondingly processed by other equipment aiming at the backed-up signaling data, the influence of the communication service caused by the equipment downtime is reduced, and the use experience of the communication function of a user is improved.
Step S31, processing, by the second session border controller, second media data and the second signaling data when the operating status is abnormal shutdown, where the second signaling data includes the backed-up first signaling data.
And when the second session boundary controller monitors that the running state of the first session boundary controller is abnormal shutdown, processing second signaling data in the current second session data through a signaling processing module of the second session boundary controller, and processing second media data in the current second session data through a media processing module.
It should be noted that the second signaling data and the second media data represent data when the operation state of the first session border controller is an abnormal shutdown condition, and the first signaling data and the first media data represent data when the operation state of the first session border controller is a normal condition, which are used for distinguishing session data that needs to be processed in the two conditions.
In addition, the second signaling data includes signaling data received from the first session border controller that was backed up and being processed before the first session border controller was abnormally stopped, and signaling data received after the first session border controller was abnormally stopped and requiring processing. I.e. the signalling data processing work of the first session border controller is taken over by the second session border controller, including the work being processed and the work to be processed.
Alternatively, before the first session border controller is abnormally stopped, the session may be divided into two types, the first type being media data of the session processed by the first session border controller, and the second type being media data of the session processed by the second session border controller. After the first session border controller is abnormally stopped, the first type of session appears to be incapable of continuing voice communication but can continue hanging up and the like for the session, and the second type of session appears to be normal at the user and is not influenced by the abnormal stop of the first session border controller.
In other embodiments, multiple session border controllers may be included, with signaling data being handled cooperatively by the multiple session border controllers, with remaining normally operating session border controllers coordinating the handling of signaling data by a first session border controller with other signaling data when the first session border controller is abnormally down.
The second session boundary controller takes over the processing work of processing the signaling data when the first session boundary controller is abnormally stopped, so that the user can continuously keep controlling the session, the influence of the communication service caused by the equipment downtime is reduced, and the use experience of the communication function of the user is improved.
Further, in this embodiment, before the step of processing the first sub-data and the first signaling data by the first session border controller, the step of processing the second sub-data by the second session border controller further includes:
receiving a plurality of first media data corresponding to a plurality of sessions through the first session border controller, and distributing the plurality of first media data according to the sequence of establishment of the plurality of sessions to form the first subdata and the second subdata, wherein the first media data corresponding to any two sessions with adjacent establishment time are the first subdata and the second subdata respectively.
When the first session boundary controller receives media data of a newly established session, determining that the media data of the previously established session is allocated as first subdata or second subdata from the first signaling module, and when the media data of the previously established session is determined to be the first subdata, allocating the media data of the session as second subdata and sending the second subdata to the second session boundary controller for processing through the second session boundary controller; when it is determined to be the second sub-data, the media data of the session is processed by the first media processing module (the media processing module of the first session border controller). Further, after determining that the session is allocated as the first sub-data or the second sub-data, recording the allocation condition in the first signaling processing module as a reference for the first session border controller to allocate media data of a session to be established next time.
In other embodiments, the load states of the two session border controllers may be obtained before the media data of the new session is allocated, and the media data of the new session is allocated to the session border controller with a lighter current load state for processing.
In this embodiment, the first media data is distributed as the first sub data and the second sub data to the two session border controllers by polling, so that the loads of the first session border controller and the second session border controller are kept balanced, the load pressure of the session border controllers is reduced, and the risk of abnormal shutdown of the session border controllers is reduced.
Further, in this embodiment, the first signaling data and the second signaling data are signaling data based on a session initiation protocol, and the first media data and the second media data are media data based on a real-time transport protocol.
The session initiation protocol is sip (session initiation protocol), which is an application layer signaling control protocol, and is used to create, modify, and release a session of one or more participants in an actual scene of the session.
The Real-time Transport Protocol is RTP (Real-time Transport Protocol), which is a network Transport Protocol that specifies the standard packet format for transmitting audio and video over the internet.
In this embodiment, the session border controller analyzes and processes signaling data (SIP) and media data (RTP) at two ends of a node, so as to implement services such as signaling interworking, traffic control, NAT traversal, call encryption and decryption, interception of illegal access, quality of service (QoS), and the like in a VoIP service, and improve the use experience of the communication function of a user.
Further, based on the foregoing embodiment, another embodiment of the session control method of the session system of the present application is provided. In this embodiment, the first session data includes first media data and first signaling data, the first media data includes first sub-data and second sub-data, and the second session data includes second media data and second signaling data. Based on this, referring to fig. 4, the method includes:
step S12, associating a preset IP address with the first session border controller, processing the first sub-data and the first signaling data with the preset IP address, and processing the second sub-data with the second session border controller;
the preset IP address is a preset fixed IP address, because the first session border controller is associated with the preset IP address, for the devices outside the session system, when communicating with the session border controller in the session system, the devices appear to communicate with the preset IP address, and the data transmitted by communication is transmitted to the first session border controller, that is, the first session border controller receives the first subdata and the first signaling data.
Step S32, associating the preset IP address by the second session border controller when the operation status is abnormal shutdown, and processing the second media data and the second signaling data by using the preset IP address.
And when the first session border controller is abnormally stopped, associating the preset IP address through the second session border controller, communicating with the devices outside the session system through the preset IP address and taking over the processing work of the first session border controller.
For the devices outside the session system, before and after the first session border controller is abnormally stopped, the first session border controller communicates with the preset IP address, and the change of the session border controller associated with the preset IP address does not affect the communication between other devices and the session system, and the target IP address to be communicated cannot be lost due to the abnormal stop of the first session border controller.
It should be noted that, for devices outside the session system, the session system appears to have a fixed preset IP, and for the inside of the session system, different session border controllers have their own IP addresses, which can be used for communication between the session border controllers. Illustratively, the preset IP addresses include ETH0: 0172.16.13.8, ETH1: 010.10.10.8 and ETH2: 0192.168.1.8, and then the IP addresses of the first session border controller include ETH0: 172.16.13.70, ETH1: 10.10.10.1, ETH2: 192.168.1.1, and the IP addresses of the second session border controller include ETH0: 172.16.13.71, ETH1: 10.10.2 and ETH2: 192.168.1.8.
In other embodiments, a device external to the session system may also be enabled to continue communicating with the session system by pushing the IP address of the session border controller that takes over processing work.
The session boundary controller for actually processing the signaling data is associated with the preset IP address and communicates with the equipment except the session system through the preset IP address, so that the other session boundary controllers can be flexibly switched to be associated with the preset IP when the session boundary controller for processing the signaling data fails, the equipment except the session system can continue to communicate with the session system without being influenced, the influence of the breakdown of the equipment on the communication service is reduced, and the use experience of the communication function of a user is improved.
Further, based on the foregoing embodiment, a further embodiment of the session control method of the session system of the present application is provided. In this embodiment, the first session data includes first media data and first signaling data, the first media data includes first sub-data and second sub-data, and the second session data includes second media data and second signaling data. Based on this, referring to fig. 5, the method includes:
step S13, making a control action on the session corresponding to the first sub-data and the second sub-data according to the first signaling data by the first session boundary controller, where the control action includes hanging up the session;
step S33, when the operation state is abnormal shutdown, the second session border controller performs a control action on the session corresponding to the second media data according to the second signaling data, where the control action includes hanging up the session.
The signaling data is data for managing and controlling session connection, and can be used for initiating session invitation for a session which is not connected yet, and can be used for hanging up the session for a session which is connected already. When the session border controller receives signaling data indicating a hanging up of a session, a corresponding handling of the hanging up of the session may be made.
The current first signalling data is processed by the first session border controller when the first session border controller is operating normally, so that the first session border controller can take control actions over the session to which the first signalling data relates. Wherein processing the corresponding session of the second sub-data by the second session border controller is included. Thus, regardless of whether media data of a session is processed by the first session border controller or the second session border controller, the first session border controller may take control action with respect to the session because signaling data corresponding to the session is processed by the first session border controller.
When the first session border controller is abnormally down, the second session border controller processes the current second signaling data, so the second session border controller can take control action on the session to which the second signaling data relates. Wherein, because the second signaling data comprises the signaling data being processed before the first session border controller is abnormally stopped and the signaling data needing to be processed which is received after the first session border controller is abnormally stopped, the second session border controller can take over the session being processed before the first session border controller is abnormally stopped and control the subsequent newly initiated session.
In other embodiments, a plurality of session border controllers may be included, the signaling data is cooperatively processed by the plurality of session border controllers, and each session border controller controls a corresponding dialog according to the signaling data responsible for processing; when the first session border controller is abnormally stopped, the remaining normally working session border controllers coordinate to process the signaling data processed by the first session border controller and other signaling data and perform corresponding control.
When the first session boundary controller works normally, the session is controlled by the first session boundary controller, and after the first session boundary controller is abnormally stopped, the session is controlled by the second session boundary controller in a take-over mode, so that a user can keep controlling the session under the condition that the first session boundary controller is in failure or not, the influence of communication service caused by equipment breakdown is reduced, and the use experience of the communication function of the user is improved.
In addition, an embodiment of the present invention further provides a storage medium, where a session control program of a session system is stored on the storage medium, and when executed by a processor, the session control program of the session system implements the relevant steps of any embodiment of the session control method of the session system.
