Description
Technical Field
The present application belongs to the field of communications, and in particular, relates to an information transmission method and an information transmission apparatus.
Background
IMS (IP Multimedia Subsystem) is a basic scheme for providing voice and video calls over LTE (Long Term Evolution), and will also be the basis of a 5G voice scheme in the future. The IMS provides a call service through a PS (Packet Switch) domain connected based on a TCP/IP (Transmission Control Protocol/Internet Protocol) based on a Session Initiation Protocol (SIP), and makes good use of bandwidth and delay characteristics of LTE and 5G, thereby providing a high-quality call service.
In a communication network using IMS, after both parties of a call establish a call by SIP, they send and receive voice and video data packets by RTP (Real-time Transport Protocol). In the middle of the networks of the two communicating parties, there may be multimedia network element devices, such as MGWs (Media gateways), for forwarding, format conversion, filtering, etc. of voice or video data of the two communicating parties. The IMS network sends the media configuration parameters negotiated by the two communication parties through the SIP to network element equipment such as MGW and the like, and the network element equipment processes the multimedia data according to the configuration parameters.
Voice or video data is encoded using some encoding scheme, known as codec, before being transmitted over RTP. For example, the speech coding includes AMR (Adaptive Multi Rate codec), AMR-WB (Adaptive Multi Rate Wideband, Multi-mode Adaptive Multi Rate codec), EVS (enhanced Voice Services, audio coder), and the video coding includes h.264, h.265, and the like. Moreover, each codec will often have different coding rates, such as 6.6, 8.85, 12.65, 14.25, 15.85, 18.25, 19.85, 23.05 and 23.85 for AMR-WB, 9 middle code rates (kbps) each called a mode, and multiple modes put together called a mode-set.
The inventor finds that, in an actual network, due to reasons such as a temporary communication failure between network devices on a network side, a random defect of a MGW itself, a random defect of other network devices of an IMS, etc., a problem of abnormal media data conversion occurs during a call between two parties of the call, and thus call quality between the two parties of the call is affected.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The information transmission method, the information transmission apparatus, the electronic device, and the readable storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
In the call establishment process, both parties of the call need to negotiate the codec and the mode-set used in the communication through an SIP and an SDP (Session Description protocol), and the network IMS server configures the finally selected codec and mode-set to Media network element devices such as an MGW (Media Gateway) for processing Media data.
The mechanism of negotiation is typically: the calling initiator sends an SDP offer carrying all codecs and mode-sets supported by the initiator (or expected to be used by the called party), the called party selects the codecs and mode-sets in the SDP offer which the called party wishes to use, and the selection result is notified to the calling initiator through an SDP answer, so that the calling parties negotiate the media parameters to be used. Both parties to the call may then also re-initiate the negotiation by sending a new SDP offer. When media data is transmitted, both parties use the negotiated codec, and select one mode from the negotiated mode-sets to encode voice or video data, and the specific mode used can be determined by a voice data packet. The calling party can Change the Mode used by itself to send data, or can ask the other party to adjust the Mode used to send data within the negotiated Mode-set range through the CMR (Change Mode Request) flow.
Some media data abnormality problems may occur during the call, for example, when the MGW forwards data to the calling party, media data is erroneously converted into a speech packet of a null packet or a speech packet of an incorrect format, which causes a problem that the other party is silent, or a problem that media data cannot be forwarded to the other party due to a forwarding failure. When any calling party finds out the sound or image problem caused by the media data abnormity, the codec or mode used in the call is actively changed, so that the media network element equipment on the voice channel is triggered to carry out parameter reconfiguration, or the data processing flow or algorithm is changed, the network is guided to leave the processing logic with the problem, and the aim of repairing partial voice data errors to a certain extent is achieved. The examples of the application mainly have the following embodiments:
in the first scheme, codec negotiation is performed again. When any party of the call finds that the received media data has a specific condition, the negotiation of the codec is initiatively restarted. When the codec negotiation is reinitiated, the initiator may keep the original codec set or change the codec set in offer. The method for changing the codec set may include: remove the currently problematic codec, or leave the currently problematic codec but remove the currently problematic mode.
And in the second scheme, the currently used mode is switched. When any party of the call finds a particular situation with the received media data, the currently used mode is changed within the previously negotiated mode-set range.
And thirdly, performing codec negotiation again and switching the currently used mode. When any party of the call finds that the received media data has a specific condition, the negotiation of the codec is initiatively re-initiated, and the currently used mode is changed within the previously negotiated mode-set range.
For the first scheme, when the terminal finds a problem, the terminal does not just wait for the end of the call, but initiates the codec negotiation flow again to trigger the network to reconfigure the media network element device on the media path with the problem, so as to achieve the purposes of resetting the media network element device and repairing the current problem.
Fig. 1 shows one of flowcharts of an information transmission method according to an embodiment of the present application, where the information transmission method may include:
in step 102, MO (calling terminal) initiates a call and includes a supported codec list in SDP offer.
The codec list includes codec1, codec2, codec3, and the like, and in general, the SDP offer can give priority to the codecs in the codec list.
In step 104, after receiving the call request initiated by the MO, the MT (called terminal) selects codec1 in the SDP offer and replies to the MO in the SDP answer.
In general, the MT will preferentially select the codec with the highest priority in the SDP offer when it supports the MT, and at the same time, the MT will select the subset of the mode-set that the MT desires to use within the mode-set range of codec1 in the SDP offer, and also reply to the MO together with the SDP answer. In the present embodiment, it is assumed that codec1 and subset1 are selected.
And step 106, after the MO and the MT complete the subsequent interaction, the call is established, and the MO and the MT start the call.
At this time, MO and MT perform speech codec using codec 1. And when the two parties send own voice data, one mode can be selected in subset1 according to a local policy. During the subsequent call, the mode can be adjusted within the subset1, and can also be adjusted within the subset1 by referring to the feedback of the voice data receiver.
And step 108, when the MO detects that the voice packet has a problem, observing whether the problem continuously appears.
It should be noted that, either MO or MT can detect that a problem occurs in a voice packet, and this embodiment is taken as an MO example. The voice packet problem mentioned here includes, but is not limited to, any of the following cases:
(1) no RTP data packet is received;
(2) the received RTP data packet only has an RTP packet header and no RTP payload;
(3) the received RTP data packet has an RTP header and an RTP payload, but the decoded silence data is caused by the abnormity of the RTP payload.
In these cases, the terminal cannot automatically adjust the voice codec scheme by the RTP or RTCP method according to the existing protocol.
And when the terminal detects any abnormality, timing is started to observe whether the problem occurs for a period of time.
In step 110, when the problem lasts for a certain time, the MO re-sends the SDP offer to negotiate.
Note that, in fact, the MT may also send the SDP offer to initiate negotiation again when finding a problem, and this embodiment is taken as an MO example. When the MO sends the SDP offer, the following steps may be performed:
(1) maintaining all codecs carried in the original SDP offer;
(2) removing codec1 used when the current problem occurred;
(3) codec1, which was currently used when the problem occurred, is retained, but the currently used mode is removed from mode-set;
(4) adding or removing other codecs or modes that it believes may affect speech.
For (4), for example, codec1 is currently used when a problem occurs, but codec3 is determined by analysis to be likely to affect speech, then codec3 is removed.
In step 112, after receiving the new SDP offer of the MO, the MT reselects codec and replies to the MO in the SDP answer.
After receiving the new SDP offer, the MT may generate an SDP answer reply to the MO, and the MT may specifically perform the following steps:
(1) selecting the codec with the highest priority according to the original logic and selecting the subset of the mode-set expected to be used;
(2) if the MT finds the current speech again to be problematic, the currently used codec and/or mode (as indicated by the new SDP offer) may be selectively ignored, and a new codec or mode-set subset may be selected.
Furthermore, since the codec was renegotiated before, the media network element devices of the media path need to be reconfigured. The reconfiguration operation can effectively assist the media path in parameter restoration so as to solve the problems at present. Similar to the situation that the computer or the mobile phone is restarted to solve the problem, the call can be continued.
For the second scheme, when the terminal finds a problem, instead of just waiting for the end of the call, the terminal actively changes the currently used mode within the negotiated mode-set range, and triggers the network side media path to reconfigure or enter different code processing logics, so as to achieve the purpose of resetting the media network element device and repairing the current problem.
Fig. 2 shows a second flowchart of an information transmission method according to an embodiment of the present application, where the information transmission method may include:
in step 202, MO (calling terminal) initiates a call and includes a supported codec list in SDP offer.
In step 204, after receiving the call request initiated by the MO, the MT (called terminal) selects codec1 in the SDP offer and replies to the MO in the SDP answer.
In step 206, after the MO and the MT complete the subsequent interaction, the session is established, and the two parties start to talk.
And step 208, when the MO detects that the voice packet has a problem, observing whether the problem continuously appears.
The steps 202 to 208 in this embodiment are the same as the steps 102 to 108, and are not described herein again.
The MO should now ask the MT to use another mode than the one currently used, and the newly selected mode should be selected in subset1, as described above with reference to steps 102 and 104.
In step 212, after receiving the CMR, the MT changes the currently used mode according to the protocol to transmit data.
As mentioned above, the MT (i.e. the data receiving end) can derive the mode used by the current data from the RTP packet header or other characteristics of the RTP packet. Therefore, when the MO changes mode, the MT can be detected, and the media network element device of the network can also be detected. At this time, due to the change of the mode, the media network element device on the network side needs to switch the data processing algorithm or flow, so that the network can be triggered to leave the processing logic with the problem, and the current media data problem is repaired.
For the third scheme, the terminal may use the first scheme and the second scheme in a combined manner, for example, try to use the second scheme first, and use the first scheme when the problem is not solved.
The first electronic device side (i.e., the calling terminal) according to the embodiment of the present application will be described below. Fig. 3 shows a third flowchart of an information transmission method according to an embodiment of the present application, where the information transmission method may include:
step 302, the first electronic device sends the first coding information to the second electronic device when detecting that the error information occurs in the communication data packet between the first electronic device and the second electronic device.
Wherein the error information at least comprises one of the following: the communication data packet is not received, the communication data packet does not comprise a payload, and the payload of the communication data packet is abnormal.
In this embodiment, in the case where the first electronic device establishes a call with the second electronic device, when the first electronic device detects that the communication data (i.e., the media data) has an error, first encoding information indicating encoding information usable by the second electronic device is transmitted to the second electronic device. According to the embodiment of the application, when the first electronic device finds that a call problem occurs, the second electronic device is triggered to reconfigure the corresponding coding information by re-initiating the coding information determination process instead of just waiting for the call to be ended, so that the purpose of repairing the problem of the current call caused by the media data conversion error is achieved, and the call quality and the call efficiency between the devices are improved.
In addition, a control network element device and a media network element device are connected between the first electronic device and the second electronic device, the media network element device is used for processing media data (i.e. communication data), and the control network element device can control the media network element device. After the first electronic device and the second electronic device re-determine the coding information, the network element device is triggered to perform parameter reconfiguration on the media network element device on the voice channel, or perform change of a data processing flow or an algorithm, and the network is guided to leave a processing logic with problems, so that the purpose of repairing partial media data errors to a certain extent is achieved.
It should be noted that the first electronic device or the second electronic device includes a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted electronic device, a wearable device, a personal computer, and the like.
In some embodiments of the present application, a process of a first electronic device establishing a call with a second electronic device includes: the first electronic equipment sends a call request carrying second coded information to the second electronic equipment; the first electronic equipment receives second coding use information sent by the second electronic equipment; in response to the second encoding usage information, the first electronic device establishes communication with the second electronic device. The second coding information includes a coding mode which can be used or expected to be used and a coding rate which can be used or expected to be used, and the second coding use information includes a second electronic device which is determined to be used by the second electronic device and the coding rate which is determined to be used.
In this embodiment, the first electronic device does not receive the communication data packet, or the first electronic device receives the communication data packet, the communication data packet has a header and no payload, or the first electronic device receives the communication data packet, the communication data packet has a header and a payload, but the decoded data is silent data due to the abnormal payload. The above error information may cause problems of silence, noise, video jamming, etc. to the first electronic device. Therefore, when the first electronic device detects any one of the above information, the encoding information is actively changed, and the problem of the current media data can be timely repaired.
In some embodiments of the present application, the first electronic device sending the first encoded information to the second electronic device includes: the first electronic equipment sends the coding mode information to the second electronic equipment.
In this embodiment, the first encoding information includes encoding mode information, that is, the first electronic device and the second electronic device perform negotiation of an encoding mode again, and re-determine an encoding mode used between the first electronic device and the second electronic device, so that the problem of current call is solved, and the call quality between the first electronic device and the second electronic device is improved.
In some embodiments of the present application, the encoding mode information includes at least one of: the information of the original coding mode, the information of the residual coding mode of the coding mode which does not include the error information in the original coding mode, the information of the residual coding mode which does not include the coding rate corresponding to the error information in the original coding mode, and the information of the residual coding mode which does not include the coding mode or the coding rate causing the error information to appear in the communication data packet in the original coding mode.
In this embodiment, in one case, the first electronic device may send the original encoding mode to the second electronic device, that is, continue to send the encoding mode sent when the call is established, and the second electronic device reselects the encoding mode after receiving the original encoding mode; in another case, after removing the coding mode used when the current problem occurs from the original coding modes, the first electronic device sends the remaining coding modes to the second electronic device; in another case, the first electronic device retains the coding mode used when the current problem occurs in the original coding mode, but removes the currently used coding rate from the set of removed current coding rates, and then sends the remaining coding mode to the second electronic device; in another case, the first electronic device removes the coding mode or coding rate that has an adverse effect on the communication data packet from the original coding mode, and sends the remaining coding modes to the second electronic device, where the coding mode or coding rate that has an adverse effect on the communication data packet is the coding mode or coding rate that may cause the communication data packet to have error information. For example, codec1 is currently used when a problem arises, but codec3, which was analytically determined to likely affect speech, then codec3 is removed.
Through the mode, the second electronic equipment reconfigures the used coding mode after receiving the coding mode information sent by the first electronic equipment, and the problems of silence, noise, video blockage and the like are solved.
In some embodiments of the present application, the first electronic device sending the first encoded information to the second electronic device includes: the first electronic device sends the specified encoding rate to the second electronic device.
In this embodiment, the first encoding information includes a specified encoding rate, that is, the first electronic device actively changes the currently used mode within the negotiated mode-set range when establishing a call with the second electronic device, specifically, the first electronic device requests the second electronic device to change a mode for data transmission by sending a CMR within the negotiated mode-set range, so as to repair a problem of a current call and improve call quality between the first electronic device and the second electronic device.
It should be noted that, in some embodiments, after the first electronic device detects the error information of the communication data packet, the first electronic device may send the coding mode information to the second electronic device, and if the error problem is not solved by this mode, then send the specified coding rate to the second electronic device; or, the specified encoding rate may be sent to the second electronic device first, and if the error problem is not solved in this way, the encoding mode information may be sent to the second electronic device. By the method, double guarantees can be provided for repairing the current call problem.
In some embodiments of the present application, after step 304, the method further comprises: the first electronic equipment receives the first code using information sent by the second electronic equipment.
In this embodiment, after the first electronic device sends the first encoding information to the second electronic device, the second electronic device resets the encoding information itself, and then feeds back the reset encoding mode and encoding rate (i.e., the first encoding usage information) to the first electronic terminal. After receiving the first code using information, the first electronic device can use the information to realize continuous communication with the second electronic device, and smooth communication between the devices is ensured.
The second electronic device side (i.e., the called terminal) according to the embodiment of the present application will be described below. Fig. 4 shows a fourth flowchart of an information transmission method according to an embodiment of the present application, where the information transmission method may include:
in step 404, the second electronic device sets first encoding usage information according to the first encoding information.
In this embodiment, in a case where the second electronic device establishes a call with the first electronic device, when the first electronic device detects that the communication data (i.e., the media data) has an error, the first electronic device transmits, to the second electronic device, first encoded information indicating encoded information usable by the second electronic device. And after receiving the first coding information, the second electronic equipment resets the coding information used by the second electronic equipment according to the first coding information. According to the embodiment of the application, when the first electronic device finds that a call problem occurs, the second electronic device is triggered to reconfigure the corresponding coding information by re-initiating the coding information determination process instead of just waiting for the call to be ended, so that the purpose of repairing the problem of the current call caused by the media data conversion error is achieved, and the call quality and the call efficiency between the devices are improved.
It should be noted that the second electronic device or the first electronic device includes a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted electronic device, a wearable device, a personal computer, and the like.

The second coding information includes a coding mode which can be used or expected to be used and a coding rate which can be used or expected to be used, and the second coding use information includes a second electronic device which is determined to be used by the second electronic device and the coding rate which is determined to be used.
In some embodiments of the present application, after the second electronic device sets the first encoding usage information according to the first encoding information, the method further includes: the second electronic equipment resets the first coding use information under the condition that error information of a communication data packet between the second electronic equipment and the first electronic equipment is detected; wherein the error information at least comprises one of the following: the communication data packet is not received, the communication data packet does not comprise a payload, and the payload of the communication data packet is abnormal.
In this embodiment, after resetting the code usage information according to the first code information, if the occurrence of an error message is also detected, the second electronic device may ignore the currently used code usage information (i.e., the code usage information reset according to the first code information), and select a new code usage information to talk with the first electronic device. Through the embodiment of the application, the second electronic equipment can not only reset the code using information based on the error information found by the first electronic equipment, but also automatically detect the error information and further reset the code using information, and double guarantee can be provided for repairing the problem of the current call.
