The following describes a communication disconnection reconnection method according to an exemplary embodiment of the present disclosure in detail, taking a terminal device as an example of execution by a current communication terminal.
Fig. 3 shows a flow of a communication disconnection reconnection method in the present exemplary embodiment, which may include the following steps S310 to S340:
in step S310, real-time communication is performed with the target communication terminal through the established first communication link and the second communication link.
In an exemplary embodiment, the first communication link may be a link for exchanging related parameter information, for example, the first communication link may be a communication link formed by a signaling server and at least two communication terminals participating in real-time communication, may be used for exchanging related parameter information between the at least two communication terminals, and may also be used for sending attribute information for constructing the communication link to the at least two communication terminals, which is not particularly limited in this exemplary embodiment. The second communication link may be a link for transmitting media data, for example, the second communication link may be a communication link formed by a media server and at least two communication terminals participating in real-time communication, and may be used to exchange relevant media data between the at least two communication terminals, for example, in a live application scenario, the media data may be a live video stream pushed by an anchor terminal, and in a video call application scenario, the media data may be video call data sent by the two communication terminals participating in communication, which is not particularly limited in this example embodiment.
In step S320, attribute information for establishing the second communication link is received through the first communication link.
In an exemplary embodiment, the attribute information may refer to a relevant parameter for establishing the second communication link, for example, when the media server forming the second communication link is a pass-through server, the attribute information may be authentication information corresponding to the pass-through server, and of course, the attribute information may also be a network address, identification information of the server, and the like, which is not particularly limited in this exemplary embodiment.
In step S330, upon detecting an abnormal disconnection of the communication network, if the communication network recovers within a predetermined target reconnection time threshold, a new second communication link is established according to the newly received attribute information.
In an exemplary embodiment, the target reconnection time threshold refers to a preset time threshold for determining whether reconnection is overtime, for example, the target reconnection time threshold may be 100ms or 1s, which is not particularly limited in this exemplary embodiment. Specifically, a function of setting the target reconnection time threshold may be provided through a packaged API interface, the API interface may be integrated in a Software Development Kit (SDK) corresponding to the RTC, and the target reconnection time threshold may be freely set by a service party according to different application scenarios. The latest received attribute information refers to the attribute information received at the latest time point when the abnormal disconnection of the communication network is detected, and the latest received attribute information can ensure that all the attribute information (such as authentication information) is effective when the second communication link is established, so that the success rate of establishing the second communication link is improved. The new second communication link refers to the second communication link that is restored to be established by the newly received attribute information, with respect to the second communication link before the communication network is abnormally disconnected.
In step S340, the real-time communication with the target communication terminal is resumed through the new second communication link.
In an exemplary embodiment, when the communication network is recovered, a new second communication link may be reestablished through the latest attribute information, and real-time communication with the target communication end is continued through the new second communication link, so as to implement disconnection and reconnection of the second communication link.
The following further describes steps S310 to S340 in fig. 3.
In an exemplary embodiment, while the attribute information for establishing the second communication link is periodically received through the first communication link, the unification of the target reconnection time thresholds of different communication ends may also be implemented through the steps in fig. 4, and as shown in fig. 4, the specifically may include:
step S410, acquiring a preset first reconnection time threshold;
step S420, obtaining a second reconnection time threshold corresponding to the target communication end through the first communication link;
step S430, determining a target reconnection time threshold according to the first reconnection time threshold and the second reconnection time threshold, and sending the target reconnection time threshold to the target communication end through the first communication link.
The first reconnection time threshold may be a reconnection time threshold corresponding to the terminal device that is set by calling the API interface when the current communication terminal establishes real-time communication with the target communication terminal, for example, the first reconnection time threshold may be 100ms or 200ms, which is not limited in this example embodiment. The second reconnection time threshold may be a reconnection time threshold corresponding to the target communication end, where the target communication end is set through the API interface when establishing real-time communication with the target communication end, for example, the first reconnection time threshold may be 300ms or 400ms, and this example embodiment is not limited to this. Since the first reconnection time threshold and the second reconnection time threshold are respectively set at the terminal device and the target communication terminal, the first reconnection time threshold and the second reconnection time threshold may be the same or different. However, when the first reconnection time threshold is different from the second reconnection time threshold, reconnection failure may be caused, the reconnection success rate of the communication link may be reduced, the reconnection time threshold of the target communication end is exchanged through the first communication link, the target reconnection time threshold is determined according to the obtained first reconnection time threshold and the obtained second reconnection time threshold to complete unification of the reconnection time thresholds, and the unified target reconnection time threshold is sent to the target communication end.
The reconnection time threshold of the current communication end and the target communication end is unified into the target reconnection time threshold, so that the situation that the reconnection time is overtime is judged by the current communication end and the target communication end according to the unified reconnection time threshold is guaranteed, and the reconnection success rate of a communication link is improved.
Specifically, the unification of the first reconnection time threshold and the second reconnection time threshold may be implemented by the steps in fig. 5, and as shown in fig. 5, the method specifically includes:
step S510, taking a maximum value of the first reconnection time threshold and the second reconnection time threshold as the target reconnection time threshold; or
Step S520, taking the minimum value of the first reconnection time threshold and the second reconnection time threshold as the target reconnection time threshold; or
Step S530, taking an average value corresponding to the first reconnection time threshold and the second reconnection time threshold as the target reconnection time threshold.
The maximum value or the minimum value of the first reconnection time threshold and the second reconnection time threshold, or the average value corresponding to the first reconnection time threshold and the second reconnection time threshold is used as a unified target reconnection time threshold, only a unified partial mode of the reconnection time thresholds is realized, the unification of the reconnection time thresholds can be quickly realized through the maximum value, the minimum value or the average value, the calculated amount is small, and the efficiency of determining the target reconnection time threshold is improved. Of course, the target reconnection time threshold may also be determined by measuring the current network delay time and combining the network delay time, the first reconnection time threshold, and the second reconnection time threshold, which is not particularly limited in this example embodiment.
In an exemplary embodiment, the second communication link may include a pass-through server, and the attribute information may be authentication information corresponding to the pass-through server, and the signaling server in the first communication link may periodically request the most recent authentication information from the pass-through server and may send the most recent authentication information to the current communication end through the first communication link, so that the current communication end can pass the authentication of the pass-through server when establishing the second communication link according to the authentication information received periodically.
Further, the determination of the request period may be implemented by the steps in fig. 6, and as shown in fig. 6, the determining may specifically include:
step S610, obtaining redundant data, wherein the redundant data comprises network interaction time;
step S620, determining the request period according to the expiration time corresponding to the authentication information, the target reconnection time threshold, and the network interaction time.
The redundancy data may be an extra data amount set to avoid failure of the authentication information when the request period of the authentication information is set, for example, the redundancy data may be network interaction time, or network delay time, or of course, other data that may cause failure of the authentication information may also be used, which is not particularly limited in this example embodiment. The setting of the redundancy data mainly considers that the authentication information needs to be interacted through a network, and the network interaction needs to consume a certain time, so as to further ensure that the authentication information is still valid when in use, a certain amount of redundancy data is set for offsetting the overhead of the network interaction time for requesting new authentication information.
For example, assuming that the valid time of the authentication information is 10s, the request period for setting the authentication information cannot be directly set to 10s, and since the signaling server requests the authentication information from the pass-through server and sends the authentication information to the target communication end through the first communication link, there is also consumption of network interaction time, for example, the network interaction time may be 2s, redundant data such as network interaction time is used as one of the parameters for calculating the request period, and it is ensured that the authentication information transmitted to the current communication end and the target communication end each time is not invalid, at this time, the request period of the authentication information should be at least 8s, and of course, if there are other possible time consumptions, it should also be used as redundant data, which is not limited in this example.
The expiration time corresponding to the authentication information is the valid time of the authentication information, for example, after the expiration time corresponding to the authentication information is 10s, it indicates that the valid time of the authentication information is 10 s. Specifically, the request period may be calculated by the relation (1):
T＝T1-T2-Tk (1)
wherein T may represent a request period of authentication information, T1Can indicate the effective time, T, of the authentication information2May represent a target reconnect time threshold, TkThe set redundancy data can be represented.
In an exemplary embodiment, if the communication network recovers within the target reconnection time threshold, a new second communication link may be established according to the latest received attribute information, and of course, if the communication network does not recover within the target reconnection time threshold, disconnection reconnection failure information is fed back, so that the user ends the current real-time communication or manually reconnects to implement communication according to the fed-back disconnection reconnection failure information, thereby improving the disconnection reconnection efficiency.
In an exemplary embodiment, whether the new second communication link is reconnected successfully may be tested through the steps in fig. 7, and as shown in fig. 7, the testing specifically may include:
step S710, sending test information to the target communication terminal through the new second communication link;
step S720, if the test information is successfully sent, the real-time communication with the target communication end is recovered through the new second communication link;
step S730, if the sending of the test information fails, the test information is repeatedly sent to the target communication terminal within the target reconnection time threshold until the sending of the test information is successful or disconnection reconnection failure information is fed back when the target reconnection time threshold is exceeded.
After the test information is sent to the target communication terminal, if the test information is successfully received by the target communication terminal, it indicates that the new second communication link has recovered the real-time communication, so that the real-time communication with the target communication terminal can be recovered through the successfully established new second communication link. If the sending of the test information fails, the new second communication link does not recover the real-time communication, so that the test information can be repeatedly sent to the target communication end within the target reconnection time threshold until the test information is successfully sent, or the disconnection reconnection failure information is fed back when the target reconnection time threshold is exceeded.
Fig. 8 schematically illustrates a flow chart of reconnecting the second communication link in an exemplary embodiment of the present disclosure.
Referring to fig. 8, in step S801, a first reconnection time threshold corresponding to a current communication end and a second reconnection time threshold corresponding to a target communication end are set through a packaged API interface according to different requirements;
step S802, exchanging a first reconnection time threshold and a second reconnection time threshold through a first communication link, and determining a uniform target reconnection time threshold according to the first reconnection time threshold and the second reconnection time threshold;
step S803, periodically requesting attribute information for establishing a second communication link through the first communication link according to a pre-calculated request period, so as to ensure the validity of the attribute information such as authentication information when disconnection and reconnection are carried out and ensure the success rate of disconnection and reconnection;
step S804, the communication network is disconnected abnormally, and the second communication link is disconnected;
step S805, determining whether the communication network is recovered within the target reconnection time threshold, if the communication network is recovered within the target reconnection time threshold, executing step S806, otherwise executing step S807;
step S806, establishing a new second communication link according to the latest received attribute information;
step S807, when the communication network is not recovered within the target reconnection time threshold, the reconnection of the second communication link is considered to be failed, and disconnection reconnection failure information is fed back to the user, so that the user actively finishes the real-time communication or manual reconnection;
step S808, sending test information to a target communication terminal through a new second communication link;
step S809, determining whether the test information is successfully transmitted, if the test information is successfully transmitted, executing step S810, otherwise executing step S811;
step S810, the second communication link is reconnected successfully;
step S811, judging whether the reestablishment of the second communication link exceeds the target reconnection time threshold, if the reestablishment of the second communication link exceeds the target reconnection time threshold, executing step S812, otherwise, returning to execute step S808 and step S809;
step S812, the second communication link fails to reconnect, and feeds back information of the disconnection reconnection failure to the user.
In an exemplary embodiment, the reconnecting of the first communication link may be implemented by the steps in fig. 9, and as shown in fig. 9, the reconnecting specifically may include:
step S910, when the abnormal disconnection of the first communication link is detected, determining the communication state of the second communication link;
step S920, if the communication state is a disconnection state, establishing a new first communication link with the signaling server in a long connection communication mode within the target reconnection time threshold value so as to recover the communication with the signaling server through the new first communication link, and feeding back disconnection reconnection failure information when the target reconnection time threshold value is exceeded;
step S930, if the communication status is a connection status, repeatedly attempting to establish a new first communication link with the signaling server in a long connection communication manner until communication with the signaling server is resumed through the new first communication link or an instruction for actively ending real-time communication is received.
The communication state of the second communication link refers to a parameter characterizing the second communication link, for example, the communication state of the second communication link may be a connected state or a disconnected state, which is not limited in this example embodiment. Because the first communication link (such as a signaling link) and the second communication link (such as a media link) are independent of each other, if the first communication link is abnormally disconnected due to a non-network reason, the second communication link is not necessarily disconnected at this time. In addition, the first communication link assists in establishing the second communication link, and does not directly transmit media data, so that if the communication state of the second communication link is a connection state or after the establishment is resumed, the independent disconnection of the first communication link has little influence on a user, and therefore, only when the first communication link and the second communication link are disconnected simultaneously, a timeout judgment mechanism exists, otherwise, the first communication link tries to be reconnected until the first communication link succeeds or the user actively ends the call, the reconnection success rate of the real-time communication link is further improved, and the reliability of the real-time communication link is improved.
Fig. 10 schematically illustrates a flow chart of reconnecting a first communication link in an exemplary embodiment of the present disclosure.
Referring to fig. 10, step S1001 of establishing a first communication link and executing step S1002 when detecting that the first communication link is abnormally disconnected;
step S1002, reestablishing a first communication link in a long connection communication mode;
step S1003, determining whether the long connection communication is successfully reestablished, if it is determined that the long connection communication is successfully reestablished, executing step S1004, otherwise executing step S1007;
step S1004, reentering the room of the signaling server;
step S1005, judging whether the room of the signaling server is successfully entered, if so, executing step S1006, otherwise, executing step S1010;
step S1006, the first communication link is successfully reestablished;
step S1007, judging whether the user actively finishes the current real-time communication, if so, finishing the process, otherwise, executing step S1008;
step S1008, determining whether the communication state of the second communication link is a disconnected state, if it is determined that the communication state of the second communication link is the disconnected state, executing step S1009, otherwise returning to execute step S1002;
step S1009, determining whether the reestablishment of the first communication link exceeds the target reconnection time threshold, if it is determined that the reestablishment of the first communication link exceeds the target reconnection time threshold, executing step S1010, otherwise, returning to execute step S1002;
in step S1010, the first communication link is failed to be reestablished.
In summary, in the exemplary embodiment, on one hand, the first communication link periodically receives the attribute information for establishing the second communication link, so that the latest attribute information can be ensured when the communication network is abnormally disconnected, and a new second communication link is established according to the latest attribute information, thereby avoiding a situation that the server cannot be successfully reconnected due to failure of the authentication information under the condition of authentication, improving the success rate of disconnection reconnection, and improving the reliability of real-time communication; on the other hand, the attribute information is received through the first communication link, and the communication data is transmitted through the second communication link, so that the condition that the bandwidth of the second communication link is insufficient due to the fact that the attribute information is received is avoided, and the stability of the communication link is improved; on the other hand, whether the communication network is recovered or not is detected through a predetermined target reconnection time threshold, and the recovery and reconstruction of the communication link are automatically realized when the communication network is recovered, so that the recovery efficiency of real-time communication is improved.

Wherein:
the pass through server 1230 forms a second communication link with the first communication end 1210 and the second communication end 1220 for exchanging media data between the first communication end 1210 and the second communication end 1220. In an actual mobile network environment, due to the limitation of network address resources, the base station often allocates only one private network address inside the local area network to the communication terminal in an NAT manner, and does not have a direct public network communication capability, and at this time, a media link, that is, a media link (relay) portion in fig. 12, needs to be established by means of the traversal server 1230; for the small part of the case with direct public network communication capability, a link for media data exchange, i.e. the (direct) part of the media link in fig. 12, can be established directly through the public network 1250 without the help of a pass-through server.
The pass-through server 1230 may help each communication end (e.g., the first communication end 1210 and the second communication end 1220) participating in the real-time communication to obtain an Internet Protocol (IP) address and a port corresponding to the pass-through server through the STUN/TURN Protocol, and allocate a relay address to each communication end participating in the real-time communication, for example, a terminal device corresponding to the communication end does not have an IP address and a port directly usable for the public network communication, and the pass-through server 1230 may provide a network relay function through the relay address, and help each communication end participating in the real-time communication to implement exchange of media data.
The signaling server 1240, the first communication end 1210 and the second communication end 1220 form a first communication link through a long connection communication websocket, and are configured to send attribute information for constructing the second communication link to the first communication end 1210 and the second communication end 1220, where the attribute information includes authentication information penetrating through the server 1230.
The signaling server 1240 may provide basic signaling services, such as room management, media link parameter exchange, customized data exchange in a room, and the like, for each communication terminal (e.g., the first communication terminal 1210 and the second communication terminal 1220) performing real-time communication based on WebRTC.
In an exemplary embodiment, the first communication terminal 1210 may be configured to, when detecting an abnormal disconnection of the communication network, if the communication network is recovered within a predetermined target reconnection time threshold, establish a new second communication link according to the latest received attribute information, and recover real-time communication with the second communication terminal 1220 through the new second communication link.
In an exemplary embodiment, the first communication end 1210 may determine the target reconnection time threshold by using a preset first reconnection time threshold and a second reconnection time threshold corresponding to the second communication end 1220 and obtained through the first communication link, and send the target reconnection time threshold to the second communication end 1220 through the first communication link.
In an exemplary embodiment, the communication disconnection reconnection system 1200 may further include a big data analysis server 1260, where the big data analysis server 1260 may form a third communication link with the first communication end 1210 and the second communication end 1220, and the big data analysis server 1260 may obtain historical reconnection data of the first communication end 1210 and the second communication end 1220 through the third communication link, so as to determine a target reconnection time threshold according to the historical reconnection data, and send the target reconnection time threshold to the first communication end 1210 and the second communication end 1220.
And on the premise of meeting the user privacy, reporting operation and maintenance data which are irrelevant to the user identity, such as IP, connection type, reconnection time, whether reconnection is successful, and the like to the big data analysis server 1260 through a third communication link. Then, historical reconnection data is extracted according to the operation and maintenance data, for example, the historical reconnection data may include success rates at different reconnection timeout thresholds and reconnection time for a user to wait, and the big data analysis server 1260 may calculate a reasonable target reconnection time threshold according to the historical reconnection data. For the scene with low user personalized requirements in the aspect of disconnection reconnection, a target reconnection time threshold value calculated by a big data analysis server can be selected, and the success rate of disconnection reconnection is further improved.
