Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
According to a line supported by a terminal, an existing private line video conference can be divided into an IP private line and an E1 private line, a protocol supported by the IP private line is an h.323 protocol or a Session Initiation Protocol (SIP), a protocol supported by the E1 private line is an h.320 protocol, and the E1 private line is an end-to-end line and has better stability. Taking an E1 private line video conference as an example, fig. 1 is a schematic structural diagram of an E1 private line video conference system provided in this embodiment of the present application, as shown in fig. 1, an E1 private line video conference system includes a Multipoint Control Unit (MCU) and a plurality of E1 terminals, three E1 terminals are taken as an example in fig. 1, and when a video conference is held, signaling communication is performed between the MCU and the E1 terminals participating in the conference by using BAS codes in an h.221 frame structure.
Exemplarily, fig. 2 is a schematic view of a communication process of two communication parties in a call setup phase according to an embodiment of the present application, as shown in fig. 2, in an a-sequence capability negotiation phase, a capability set negotiation is performed between the two communication parties (MCU and E1 terminal) through a BAS capability code, in a B-sequence mode switching phase, the two communication parties determine a transmission policy of audio and video coding and a data channel according to a capability set negotiation result, and send the BAS mode code to notify a coding format and a rate of a local terminal of an opposite terminal. It is understood that, in the present embodiment, the E1 terminal communicating with the MCU may be any one of the E1 terminals in fig. 1.
The main ideas of the technical scheme are as follows: in the prior art, in the a-sequence capability negotiation stage, BAS capability codes are BAS codes of multiple capabilities in a capability set, and since each capability requires one or more BAS codes, h.221 frame data can only carry one BAS code each time, and one capability set may correspond to a large number of BAS codes, when two parties negotiate the capability set, they need to spend more time to transmit the BAS codes corresponding to the capability set, thereby causing a slow call setup speed and affecting the user experience. Based on the technical problems in the prior art, the application provides a technical scheme for private line video conference communication, in the A-sequence capability negotiation stage of call setup, capability set negotiation is performed through capability set snapshots, since the capability set snapshots are obtained by simplifying the capability sets according to agreed rules, for example, a specific identifier is set for each capability set to serve as the capability set snapshot corresponding to the capability set, only one or a few BAS codes corresponding to the capability set snapshots are needed during the capability set negotiation, the size of a BAS code set transmitted between a local terminal and a corresponding terminal is reduced, the time required by the capability set negotiation is shortened, and the call setup speed of a private line video conference is accelerated.
Example one
Fig. 3 is a flowchart of a private line video conference communication method according to an embodiment of the present application, where the method according to this embodiment may be executed by a private line video conference communication device provided in the embodiment of the present application, and the device may be implemented by software and/or hardware, and may be integrated in a private line video conference device (e.g., the MCU or the E1 terminal in fig. 1). As shown in fig. 3, the private line video conference communication method of the embodiment includes:
s101, sending a first home terminal BAS code set to the remote equipment.
In this embodiment, a device that initiates a video conference first may be called a home terminal, and a device that communicates with the home terminal may be called a far-end, and it can be understood from fig. 2 that, if the home terminal is an MCU, the far-end is an E1 terminal, and if the home terminal is an E1 terminal, the far-end is an MCU.
For the convenience of distinction, in this embodiment, a set composed of BAS codes of the snapshot of the local terminal capability set corresponding to the local terminal capability set, which is sent to the remote terminal by the local terminal, is called a first local terminal BAS code set.
In a possible implementation manner, when a video conference is initiated, a local terminal selects a local terminal capability set from a plurality of local terminal capability sets configured in advance as a target local terminal capability set used in the communication process, then a target local terminal capability set snapshot corresponding to the target local terminal capability set is determined according to a mapping relation between the local terminal capability set and the local terminal capability set snapshot, and finally a first local terminal BAS code set is generated according to the target local terminal capability set snapshot and sent to a remote terminal.
In this embodiment, each home terminal capability set corresponds to a capability combination form of the home terminal, for example, a certain device has 3 video capabilities, 2 audio capabilities, and 3 data transmission capabilities, and by combining the capabilities of different categories, a plurality of different capability sets can be obtained.
In this embodiment, the capability set snapshot is obtained by simplifying the capability set, and a capability set snapshot generating rule may be set in advance, for example, different parameter values (numbers, letters, or the like) are used as capability set snapshots corresponding to different capability sets to describe the capability sets. It will be appreciated that the capability set and the capability set snapshots have a one-to-one mapping relationship, and that different capability sets correspond to different capability set snapshots that are also different.
In this embodiment, the capability set snapshots corresponding to all the capability sets may be generated in advance according to the capability set snapshot generation rule, and at the same time, the mapping relationship between the capability sets and the capability set snapshots is generated and stored. Illustratively, the mapping of the capability set to the capability set snapshot may be stored in the form of a table in the private line video conference device.
In another possible implementation manner, after the target home terminal capability set is selected, in this embodiment, it may be determined whether a snapshot of the target home terminal capability set exists at the home terminal in a table lookup manner, and if the snapshot does not exist, a snapshot of the target home terminal capability set corresponding to the target home terminal capability set is generated according to a capability set snapshot generation rule and the target home terminal capability set, and then a first home terminal BAS code set is generated according to the snapshot of the target home terminal capability set, and the first home terminal BAS code set is sent to the remote terminal, and meanwhile, a mapping relationship between the target home terminal capability set and the target home terminal capability set is generated and stored.
S102, receiving a first remote BAS code set sent by a remote device.
For convenience of distinction and description, in this embodiment, the BAS code set corresponding to the first home BAS code set sent by the remote end is called a first remote BAS code set.
As can be seen from fig. 2, in the a-sequence capability negotiation stage, the two communicating parties need to exchange BAS code sets, and in this embodiment, when the remote end receives the first remote BAS code sent by the home end, a method similar to S101 is also adopted to determine the capability set used by the current communication, and notify the home end. The specific informing mode is to send the first remote BAS code set to the home terminal, and accordingly, the home terminal receives the first remote BAS code set.
And S103, negotiating a capability set with the remote equipment according to the BAS codes in the first remote BAS code set.
In this embodiment, the capability set negotiation policy is divided into a capability set snapshot mode capability negotiation policy and a capability set mode capability negotiation policy according to whether the capability set snapshot or the capability set is adopted in the a-sequence capability negotiation stage. When a video conference is initiated, the local terminal defaults to perform capability set negotiation with the remote terminal through the capability set snapshot mode capability negotiation policy, but since it is unknown whether the remote terminal supports the capability set snapshot mode capability negotiation policy, that is, the remote terminal may support the capability set snapshot mode capability negotiation policy or may not support the capability set snapshot mode capability negotiation policy, in this embodiment, it is also necessary to determine whether the capability set negotiation can be performed by continuously adopting the capability set snapshot mode capability negotiation policy.
The BAS codes in the first set of remote BAS codes are different depending on the capability negotiation policy supported by the remote. Specifically, if the remote supports the capability negotiation policy in the capability set snapshot mode, the first remote BAS code set only includes BAS codes of the remote capability set snapshot; if the remote supports the capability set mode capability negotiation policy, the first remote BAS code set has two cases, one is the BAS code including only the remote capability set, and the other is the BAS code including the BAS code of the remote capability set and the BAS code of the remote capability set snapshot.
In this step, after S102, it is necessary to finally determine, according to different BAS codes in the first remote BAS code set, a capability set negotiation policy used for performing capability set negotiation with the remote end, and further perform capability set negotiation with the remote end in different corresponding manners.
Optionally, different BAS capability code formats may be set for the capability set snapshot and the capability set in advance, and accordingly, in this step, the type of the BAS code in the first remote BAS code set may be determined by analyzing the format of the BAS code in the first remote BAS code set, and according to the determined type, it is determined whether the remote end supports the capability negotiation policy in the capability set snapshot manner.
In a possible implementation manner, in this embodiment, the capability set negotiation with the remote device is performed according to the BAS codes in the first remote BAS code set, which includes the following two possible cases:
(1) if the BAS codes in the first remote BAS code set are determined to be BAS codes of the remote capability set snapshot through analysis, it may be determined that the remote device supports the capability negotiation policy in the capability set snapshot manner.
If the corresponding remote capability set exists, the current condition of capability negotiation by directly adopting a capability set snapshot mode capability negotiation strategy is indicated, the capability set negotiation result of the A-sequence capability negotiation stage, namely the public capability set, is determined directly according to the local capability set and the remote capability set, and the B-sequence mode switching stage is entered according to the capability set negotiation result.
If there is no corresponding remote capability set, it indicates that the current condition for directly adopting the capability set snapshot mode capability negotiation policy to perform capability negotiation does not exist, and the capability set negotiation needs to be performed again. For convenience of differentiation and description, a BAS code set composed of BAS capability codes of the home capability set snapshot and BAS capability codes of the home capability set sent by the home device to the remote device is called a second home BAS code set, and a BAS code set composed of BAS capability codes of the remote capability set snapshot and BAS capability codes of the remote capability set sent by the remote device and received is called a second remote BAS code set. Then, according to the local terminal capability set and the remote terminal capability set, determining a capability set negotiation result of the A-sequence capability negotiation stage, namely a public capability set, and entering a B-sequence mode switching stage according to the capability set negotiation result.
It should be noted that the second home-end BAS code set includes a BAS capability code of the home-end capability set snapshot and a BAS capability code of the home-end capability set, which are a BAS capability code of the target home-end capability set selected by the home-end device in the current communication and a BAS capability code of the target home-end capability set snapshot corresponding to the target home-end capability set, and similarly, the second remote-end BAS code set includes a BAS capability code of the remote-end capability set snapshot and a BAS capability code of the remote-end capability set, which are also a BAS capability code of the target remote-end capability set selected by the remote-end device in the current communication and a BAS capability code of the target remote-end capability set snapshot corresponding to the target remote-end capability set.
It should be noted that, in this embodiment, in order to enable the remote device and the local device to subsequently and directly perform capability set negotiation by using a capability set snapshot manner capability negotiation policy, in this embodiment, the BAS capability code of the local capability set snapshot and the BAS capability code of the local capability set are set in the second local BAS code set sent to the remote device, and the BAS capability code of the remote capability set snapshot and the BAS capability code of the remote capability set are simultaneously set in the second remote BAS code set sent by the remote device, so that the local device obtains a mapping relationship between the remote capability set snapshot and the capability set, and the remote device obtains a mapping relationship between the local capability set snapshot and the capability set.
(2) If the BAS codes of the first remote BAS code set including the remote capability set are determined by parsing, it may be determined that the remote device does not support the capability set snapshot mode capability negotiation policy, that is, the remote device supports the capability set mode capability negotiation policy. Meanwhile, in order to enable the remote device to determine the capability set used by the home terminal to complete the subsequent capability set negotiation process, in this embodiment, a second home terminal BAS code set needs to be sent to the remote device, so that the remote device determines the home terminal capability set corresponding to the home terminal capability set snapshot in the home terminal BAS code set according to the BAS code of the home terminal capability set snapshot and the BAS code of the home terminal capability set included in the second home terminal BAS code set.
As can be seen from fig. 2, in this embodiment, entering the B-order mode switching phase according to the capability set negotiation result includes: the local terminal equipment determines a code stream sending strategy of capabilities of video, video and the like, namely a code stream format, adopted by the local terminal equipment according to the capability set negotiation result, determines that the code stream sending strategy is sent to the remote terminal equipment in a BAS mode code mode, receives the code stream sending strategy of capabilities of video, video and the like, adopted by the remote terminal equipment and sent by the remote terminal equipment, completes a mode switching process, and the video conference call is successfully established.
For the convenience of distinguishing, the code stream transmission strategy adopted by the local device is called a first code stream transmission strategy, the code stream transmission strategy adopted by the remote device is called a second code stream transmission strategy, meanwhile, the BAS code set of the first code stream transmission strategy sent by the local device is called a third local BAS code set, and the BAS code set of the second code stream transmission strategy sent by the remote device is called a third remote BAS code set.
In this embodiment, a first home-end bit rate allocation signal BAS code set is sent to a remote device, where the first home-end BAS code set includes BAS codes of a home-end capability set snapshot, and the home-end capability set snapshot is obtained by simplifying a home-end capability set; receiving a first remote BAS code set sent by a remote device; and negotiating the capability set with the remote equipment according to the BAS codes in the first remote BAS code set. The capability set snapshot is utilized to carry out capability set negotiation, so that the capability negotiation process is simplified, the call establishment time is shortened, and the use experience of a user is improved.

And step four, the capability set sending processing unit sends the local terminal capability set snapshot and the local terminal capability set message to the H.320 protocol processing unit. The local terminal capacity set snapshot and the local terminal capacity set message comprise a local terminal capacity set snapshot and a local terminal capacity set.
And step five, the H.320 protocol processing unit determines the BAS code set of the A sequence capability negotiation stage of the H.320 protocol capability negotiation according to the capability negotiation strategy issued by the capability set negotiation processing unit, sends the A sequence BAS code to the remote equipment and starts the capability negotiation process.
Step six, when the current capability negotiation strategy of the H.320 protocol processing unit is the capability set snapshot mode capability negotiation strategy, but when the BAS code set sent by the remote device is received and contains the BAS code of the capability set, the capability negotiation strategy is automatically changed into the capability set mode capability negotiation strategy, and the capability negotiation is restarted.
When the capability negotiation policy of the h.320 protocol processing unit is a capability negotiation policy in a capability set snapshot mode, the following process is performed:

And when receiving the empty capability set reported by the capability set receiving processing unit, the capability set negotiation processing unit sends a capability set mode capability negotiation strategy to the H.320 protocol processing unit, and the step five is returned again.
