Thus, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.
Embodiments of the present application provide a session management system, a session management method, a computer device, and a storage medium, which are described in detail below.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a session management system according to an embodiment of the present application, where the session management system 100 includes: a TCP session management module 102, a SIP session management module 104, and a SIP protocol session management module 106;
the TCP session management module 102 is configured to receive and respond to a video access request from a client, and obtain media information for receiving a video stream through a media server, so as to send the media information to the SIP session management module; the SIP session management module 104 is configured to receive the media information of the TCP session management module, acquire identity information of a target device to be accessed by the client, package the media information and the identity information into a data request, and send the data request to the SIP protocol session management module; the SIP protocol session management module 106 is configured to detect and respond to and extract the identity information in the data request according to the first status code of the SIP session management module, so as to generate a session request by using the identity information and then send the session request to the target device; wherein the session request is for requesting that a SIP session be established between the client and the target device.
Among them, TCP (Transmission Control Protocol) is a connection-oriented (connection-oriented) reliable Transport layer (Transport layer) communication Protocol based on a byte stream. In a simplified OSI (Open System Interconnection) model of a computer network, which implements functions specified by a fourth layer transport layer, UDP (User Datagram Protocol) is another important transport Protocol in the same layer, and is also a connectionless transport layer Protocol, providing a transaction-oriented simple unreliable information transfer service.
Wherein, SIP (Session Initiation Protocol) is a multimedia communication Protocol established by IETF (Internet Engineering Task Force). It is a text-based application-layer control protocol for creating, modifying and releasing sessions of one or more participants. The present invention is widely applied to CS (Circuit Switched), NGN (Next Generation Network) and IMS (IP Multimedia Subsystem) networks, and can support and apply to Multimedia services such as voice, video, data, and the like, and also can apply to feature services such as Presence, Instant Message, and the like. SIP is similar to HTTP (HyperText Transfer Protocol).
The client may be any terminal device, for example, the client may be a terminal device that includes both receiving and transmitting hardware, i.e., a device having receiving and transmitting hardware capable of performing two-way communication over a two-way communication link. Such a device may include: a cellular or other communication device having a single line display or a multi-line display or a cellular or other communication device without a multi-line display. The client may specifically be a desktop terminal or a mobile terminal, and may also be one of a mobile phone, a tablet computer, and a notebook computer. The client sends a video access request to the transcoding server, where the video access request is used to request video data of a target device, where the target device may be a camera, and particularly may be a national camera (also referred to as a GB camera), the target device may specifically be one of the cascaded devices, the data of the target device includes some data related to the target device, for example, the target device is a national camera, and the data of the target device includes a camera state, negotiation data between the target camera and the client or the session management system, and the like. The video access request may be text data in JSON (JavaScript Object Notation) format.
Among them, the media server is an important device of the next generation network. The device provides media resource functions required for implementing various services on an IP network under the control of control devices (soft switch devices, application servers), including service voice provision, conferencing, interactive response (IVR), notification, unified messaging, advanced voice services, etc. In the application Server, MSML (Media Server Markup Language, a special xml dedicated to Media Server interaction) is used to send commands such as playback to the Media Server. The media server has good tailorability and can flexibly realize one or more functions.
Specifically, referring to fig. 2 and 3, the session management system 100 further includes a transcoding server, a network packet sending module, and a media server; the TCP session management module 102 is further configured to receive, through the transcoding server, a video access request of the client; responding to a video access request, sequentially acquiring a media address and a media port for receiving a video stream through a network packet sending module and a media server as media information; the network packet sending module is used for indicating the media server to schedule the media resources to acquire the media information by utilizing the pre-configured connection pool elements; and sending the media information to the SIP session management module.
In one embodiment, a thread pool for processing the request and a message list for storing the request are respectively configured in the TCP session management module, the SIP session management module and the SIP protocol session management module.
As shown in fig. 2, the TCP session management module 102, the SIP session management module 104, and the SIP protocol session management module 106 are connected through respective message queues, that is, in the process of subsequently processing various types of requests, different modules may place requests to be processed by subsequent modules in corresponding message queues. Because each module is also configured with a thread pool, each module can instruct an idle thread in the thread pool to extract a request from a message queue managed and controlled by the previous module as a basis for subsequent processing.
Secondly, one end of the TCP session management module 102 is connected to the transcoding server through the message queue, and the other end is connected to the SIP session management module 104 through the message queue, after the client sends the video access request to the session management system 100, the client receives the video access request, and the transcoding server receives the video access request and then performs transcoding to obtain the request message that can be supported and processed by the subsequent module. For example, a video access request is transcoded into a request message in binary format. Then, the transcoding server will continue to send the request message to the message queue of the TCP session management module 102, and at least one idle thread (i.e. a thread that does not currently process any task) of the TCP session management module 102 extracts the request message from the message queue, and further transmits the request message to the network packet sending module, and the network packet sending module notifies the media server to schedule the media resource based on the pre-configured connection pool element, i.e. the connection link between the TCP session management module 102 and the network packet sending module, so as to obtain the sub-media returned by the media server as the media information.
It should be noted that the connection link between the TCP session management module 102 and the network packet sending module may be represented as a connection pool handle, and the sequence number is used to determine whether the client is continuously online, otherwise, the subsequent video access request may be processed.
In one embodiment, the TCP session management module 102 is provided with a storage unit, where the storage unit includes a forwarding list unit, a second state code unit, a media address unit, and a media port unit; the TCP session management module 102 is further configured to, in response to the video access request, determine a second state code in the second state code unit; if the second state code is failed, placing the subsequent video access request in a forwarding list unit until the second state code is updated successfully; the second state code is used for representing the response state of the video access request of the preamble, when the second state code is successful, the SIP session is established between the client and the target device, and when the second state code is failed, the SIP session is not established between the client and the target device; the media address unit is used for storing media addresses, and the media port unit is used for storing media ports.
Specifically, as shown in fig. 3, after the TCP session management module 102 extracts the request message from the message queue by using the idle thread managed by the TCP session management module, the TCP session management module may send the request message to the next SIP session management module 104 in response to the video access request corresponding to the request message. However, each video access request needs to establish a SIP session, but it takes time to establish the SIP session, and in the process, other video access requests may be received. Therefore, in order to avoid logic confusion, the remaining video access requests that are not responded need to be placed in the forwarding list unit until the processing of the previous video access request is completed, and after the SIP session is established between the client and the target device (such as a camera, especially a national standard camera), the state information of the second state code managed and controlled by the TCP session management module 102 is successfully converted, and then the remaining video access requests that are not responded can be processed according to the receiving sequence.
Further, the thread pool mentioned above can greatly utilize the efficiency of the system CPU on one hand, and can solve the problem of communication stability by combining the design of the present application on the other hand. Referring to fig. 4, when the thread pool is initialized, a request message contained in a message queue shared by all threads in the thread pool is usually "0", which means that all threads are in a state of waiting for wakeup in an initial state, and since 100 threads are required to create and start the threads, if there are 100 threads, the 100 threads must wait for the threads to enter the state of waiting for wakeup before entering the next logic, so as to ensure that all threads in the thread pool are started successfully.
Further, as shown in fig. 4, the thread pools of the three modules may be integrated into a thread pool module, and the thread pool module may be configured to determine whether a queue list "(the" list "is used to store a universal pointer" void ") is empty, if yes, wait for receiving the universal pointer and then wake up all threads, otherwise, notify an idle thread to take out and parse a request message from a message queue, and need to take out the request message from the head of the message queue. It should be noted that the request message received via the forwarding server may be inserted from the tail of the message queue, and all threads are woken up at the same time.
In one embodiment, the SIP session management module 104 is further configured to receive media information of the TCP session management module 102; wherein, the media information comprises a media address and a media port; acquiring a target platform ID and a target equipment ID of target equipment to be accessed by a client as identity information; the session management system 100 pre-stores at least one platform ID, and the at least one platform ID and the at least one device ID have a mapping relationship; generating an SIP protocol stack identifier to package the media information, the identity information and the SIP protocol stack identifier into a data request; wherein, the SIP protocol stack mark represents the mark of SIP conversation; a data request is sent to the SIP protocol session management module 106.
The media address and the media port are important parameters for positioning the sub-media resource, and at least one device can be mounted on one platform, that is, there is a platform ID associated with at least one device ID.
Specifically, referring to fig. 5, after the TCP session management module 102 sends the media information to the SIP session management module 104, the SIP session management module 104 not only receives the media information including the media address and the media port, but also extracts the target platform ID and the target device ID of the target device to be accessed, which are sent by the client, from the message queue of the TCP session management module 102, and uses the target platform ID and the target device ID as the positioning basis, i.e., the identity information, of the target device. It should be noted that, since SIP devices are all embedded devices and do not have high concurrency capability, if access requests are frequently sent to the SIP devices, network load of the SIP devices is easily caused, and a large amount of packet loss is caused.
Further, the SIP stack identifier "call-id" is generated by the SIP session management module 104 in real time, the state code managed by the SIP session management module 104 is actually bound to the state of the SIP session in the SIP protocol session management module 106, and the states mainly include the following four types: (1) the initial state is '0', the self-defined state code indicates that the SIP session is not established, and if the SIP session needs to be established, a session request needs to be sent; (2) 100 trying, which indicates that the SIP connection is being established and a session request is sent; (3) 200 ok, which indicates that the SIP session is established and the target device is sending the data required by the client to the sub-media resource; (4) 408, which indicates that the SIP session request was sent but the target device did not respond within a specified time (e.g., 3 seconds).
In one embodiment, the SIP protocol session management module 106 is further configured to receive a data request from the SIP session management module 104, and detect status information of the first status code of the SIP session management module 104; if the state information of the first state code is in an initial state, responding to the data request, and extracting the identity information and the SIP protocol stack identifier in the data request; wherein, the SIP stack identifier is generated by the SIP session management module 104; generating a session request according to the identity information and the SIP protocol stack identifier; and sending a session request to the target equipment for establishing the SIP session between the client and the target equipment.
Specifically, based on the description of the previous embodiment, if the state information of the first state code managed and controlled by the SIP session management module 104 is "0", which indicates that it is in an initial state, and further indicates that no SIP session is currently established, the SIP session may be established at this time, that is, as shown in fig. 6, the SIP protocol session management module 106 may, in response to a data request sent by the SIP session management module 104, extract the identity information and the SIP protocol stack identifier in the data request, and then package the extracted identity information and the SIP protocol stack identifier into a session request, so as to send the session request to a target device (e.g., a GB camera), so that an SIP session can be established between a client and the target device, and the target device can transmit video data required by the target device to the client based on the SIP session.
It should be noted that, in this embodiment, only how to establish the SIP session according to the first status code is described, and it can be seen from fig. 7 that the link sequence is from left to right, but if the link sequence is from right to left, the link sequence is to perform state change on the first status code and the second status code, the state change of the second status code may be successful or failed, and the state change of the first status code includes one of the above four states. Besides, the third status code managed by the SIP session management module 106 is the same.
In one embodiment, the TCP session management module 102 is further configured to detect a request number of the video access requests in the forwarding list unit; if the request quantity is null, generating an access termination message; sending an access termination message to the target device through the SIP session management module and the SIP protocol session management module 106; when receiving the access termination message, the SIP session management module 104 recovers the SIP stack identifier generated for establishing the SIP session.
Specifically, the above embodiments have described in detail how to establish the SIP session, and the present embodiment will further describe how to manage the SIP session, including terminating the SIP session. The termination of the SIP session may be in a left-to-right termination order as shown in fig. 2, or in a right-to-left termination order as shown in fig. 2.
For example, when the number of requests in the forwarding list unit is "0", an access termination message is generated, and the session termination from left to right of the above-mentioned three modules 102 to 106 is triggered, and all SIP sessions are to be sequentially recovered; when the target device transmits data to the client through the established SIP session, if BYE is sent, a state changing route from right to left is taken, the sessions are sequentially recovered, namely, no data is generated at the source of the data, and the client needs to be informed that the session is finished.
According to the session management system, through a simplified modular design, the expansibility of the system is obviously improved, and simultaneously, the session stability of the system in each service scene is synchronously improved due to the independence of services among modules, so that all service logics can be asynchronously processed, and the maintenance cost of the system is further reduced.
Referring to fig. 8, an embodiment of the present application provides a session management method, where the session management method is applied to a session management system, and the session management system includes a TCP session management module, an SIP session management module, and an SIP protocol session management module, which will be mainly illustrated below by applying the method to the session management system 100 in fig. 1, where the session management method includes steps S801 to S803, which are specifically as follows:
s801, receiving and responding to a video access request of a client through a TCP session management module, and further acquiring media information for receiving video streams through a media server to send the media information to an SIP session management module;
s802, receiving media information of a TCP session management module through an SIP session management module, acquiring identity information of a target device to be accessed by a client, packaging the media information and the identity information into a data request, and sending the data request to the SIP protocol session management module;
s803, detecting and responding to and extracting the identity information in the data request according to the first state code of the SIP session management module through the SIP protocol session management module, so as to generate a session request by using the identity information, and then sending the session request to the target device; wherein the session request is used for requesting the establishment of a SIP session between the client and the target device.
The session management method in the embodiment obviously improves the system expansibility through a simplified modular design, and simultaneously can ensure that the session stability of the system in each service scene is synchronously improved due to the independence of the services among the modules, so that all service logics can be asynchronously processed, and the system maintenance cost is further reduced.
In one embodiment, the session management system 100 may be implemented in the form of a computer program that is executable on a computer device such as that shown in FIG. 9. The memory of the computer device may store various program modules constituting the session management system 100, such as the TCP session management module 102, the SIP session management module 104, and the SIP protocol session management module 106 shown in fig. 1; the computer program constituted by the respective program modules causes the processor to execute the steps in the session management method of the respective embodiments of the present application described in the present specification.
For example, the computer device shown in fig. 9 may perform step S801 by the TCP session management module 102 in the session management system 100 shown in fig. 1. The computer device may perform step S802 by the SIP session management module 104. The computer device may perform step S803 by the SIP protocol session management module 106.
Wherein the computer device comprises a processor, a memory, and a network interface connected by a system bus. Wherein the processor of the computer device is configured to provide computing and control capabilities. The memory of the computer device includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system and a computer program.
