Among them, there have been many solutions for solving LTE voice. The most commonly used but the fastest-developing is the Internet Protocol Multimedia Subsystem (IMS)-based LTE network. Voice over LTE (VoLTE) has become the core network standard architecture in the era of the Internet Protocol (IP). In the long run, VoLTE can bring three aspects of value: First, improve wireless spectrum utilization, reduce network cost, spectrum utilization is more than 4 times that of GSM; Second, improve user experience, and improve HD voice and video coding introduced by VoLTE The quality of communication, and the duration of VoLTE calls is greatly shortened; third, the wireless integration of VoLTE and the Rich Communication Suite (RCS) can bring more rich services.

In the VoLTE system, tunable coding parameters are provided for voice and video respectively. When used, the coding parameters are adjusted by considering packet loss rate, packet loss burst, initial coding mode, etc., to implement voice quality, video quality, and system. Coordination between capacities, such as when the network is under high load, tends to use a lower encoding rate to sacrifice system quality at the expense of voice quality. In addition, other tunable multimedia parameters are provided for voice and video, that is, parameters used for grouping, such as voice packet rate, frame aggregation, redundancy level, and redundancy offset, etc., video packet aggregation, packet Segmentation and interleaving, etc. As with the voice coding parameters and the video coding parameters, the real-time transport protocol (RTP)/Real Time Transport Control Protocol (RTCP) is used to sense changes in network transmission capabilities, such as packet loss at the application layer. Rate, packet delay, etc., and then adjust the package parameters to improve the user experience.

In the implementation of the above packet parameter adjustment, the terminal is related to the network through the RTP/RTCP statistical network. Interest, in which the terminal cannot accurately identify the quality of the wireless network, and the RTP/RTCP statistical network information and information feedback period is long, and the user experience is poor.

It is also applicable to the present invention by modifying or changing other application scenarios based on the above-mentioned FIG. 1a and FIG. The scope of protection is not exemplified here.

Based on the above description, the technical solution of the present invention will be described in detail below through specific embodiments.

Referring to FIG. 2, FIG. 2 is a schematic flowchart of a method for adjusting a media adaptive parameter according to some embodiments of the present invention; as shown in FIG. 2, a method for adjusting a media adaptive parameter may include:

201. Obtain a media adaptation parameter of the communication device, where the media adaptation parameter includes a voice adaptation parameter and/or a video adaptation parameter.

The executor of the embodiment of the present invention is a radio access network device, which may be the foregoing eNB. The communication device can be a mobile terminal, or a media server with a coding and decoding function, a media gateway, and the like.

It will be appreciated that the above communication device may comprise a first communication and/or a second communication device, such as UE1 and/or UE2 as shown in Figures 1a and 1b. Therefore, the step 201 includes: acquiring the media adaptation parameter of the first communication device, and/or acquiring the media adaptation parameter of the second communication device, where the media adaptation parameter of the first communication device includes a voice adaptive parameter and/or The video adaptation parameter, the media adaptation parameters of the second communication device include speech adaptation parameters and/or video adaptation parameters.

The voice adaptation parameter includes a voice coding parameter and/or a voice group packet parameter, and the video adaptation parameter includes a video coding parameter and/or a video group packet parameter, where the voice group packet parameter includes frame aggregation and frame redundancy. At least one of the video group package parameters includes at least one of a package mode (Pack Mode) and a packet type (Packet Type). Frame redundancy includes the redundancy levels and redundancy offsets described above. The packet mode includes a single network abstraction layer unit mode, a non-interleaved mode, and an interleaved mode; the packet type includes a single network abstract layer unit (Single Network Abstraction) Layer Unit Packet), Aggregation Packet, Fragmentation Unit Packet.

The single network abstraction layer unit mode of the packet mode is for a session system conforming to the H.241 protocol of the International Telecommunication Union Telecommunication Standardization Sector (ITU-T); Is a session system that does not conform to the ITU-T organization's H.241 protocol. In the non-interleaved mode, NAL units are transmitted in the decoding order of NAL units; the interleaving mode is directed to systems that do not have end-to-end short delay requirements. This mode allows NAL units to be transmitted in the decoding order of non-NAL units.

A single network abstraction layer unit packet in a packet type (refers to encapsulating one NAL unit into one packet, that is, only one NAL unit is included in the RTP payload; the aggregation packet is to aggregate multiple NAL units in one RTP packet) The size of some H.264 NAL units, such as SEI NAL units, parameter sets, etc. are very small, some are only a few bytes, so they should be combined into an RTP package, which will help reduce the header ( RTP/UDP/IP) overhead. There are currently two classes. A type of aggregated packet includes: Single Time Aggregation Group (STAP) and Much Time Aggregation Group (MTAP). In STAP, STAP-A and STAP-B are time stamped. The combination, with the same timestamp in the NAL unit, is generally used in low latency environments. In MTAP, a 16-bit offset multi-time aggregation packet (MTAP16) and a 24-bit offset multi-time aggregation packet (MTAP24) are included, wherein different timestamps can also be combined, generally used in a high-latency network environment, such as streaming media. Application. Its packaging scheme is relatively complex, but greatly enhances the performance of streaming-based H.264. A split unit packet is a NAL unit that is split and transmitted using multiple RTP packets. According to whether the Decoding Order Number (DON) field is divided into two types, FU-A and FU-B.

It can be understood that, in the embodiment of the present invention, the radio access network device may confirm whether to adjust the media adaptation parameter of the first communication device or the second communication device, or may request the radio access by the first communication device. The network device confirms, therefore, in some embodiments of the present invention, before step 201, the method further includes: receiving a parameter adjustment request sent by the first communication device, where the parameter adjustment request is used to request confirmation whether the first adjustment is needed Media adaptation parameters of the communication device and/or media adaptation parameters of the second communication device.

The radio access network device may obtain the media adaptation parameter of the first communication device or the second communication device from the communication device, or obtain the media adaptation parameter of the first communication device or the second communication device from the core network device.

Specifically, in some implementation manners of the present invention, step 201 includes: receiving a radio resource control RRC message sent by the first communications device, where the RRC message carries media adaptation parameters of the first communications device and / or media adaptation parameters of the second communication device.

As shown in FIG. 1a and FIG. 1b, the first communication device may be UE1 or UE2. In FIG. 1a, the eNB receives an RRC message sent by UE1 or UE2, and the RRC message includes media adaptation parameters of UE1 and/or UE2. However, in FIG. 1b, when UE1 is the first communication device, UE2 is the second communication device, and eNB1 receives the RRC message sent by UE1, and the RRC message includes the media adaptation parameters of UE1 and/or UE2. When UE2 is the first communication device, UE2 is the first communication device, and eNB2 receives the RRC message sent by UE2, and the RRC message includes the media adaptation parameters of UE1 and/or UE2.

In another implementation manner of the present invention, the step 201 may further include: receiving a media access control MAC message sent by the first communications device, where the MAC message carries the first communications Media adaptation parameters of the device and/or media adaptation parameters of the second communication device.

As shown in FIG. 1a and FIG. 1b, the first communication device may be UE1 or UE2. In FIG. 1a, the eNB receives a MAC message sent by UE1 or UE2, and the MAC message includes media adaptation parameters of UE1 and/or UE2. However, in FIG. 1b, when UE1 is the first communication device, UE2 is the second communication device, and eNB1 receives the MAC message sent by UE1, and the MAC message includes the media adaptation parameters of UE1 and/or UE2. When UE2 is the first communication device, UE2 is the first communication device, and eNB2 receives the MAC message sent by UE2, and the MAC message includes the media adaptation parameters of UE1 and/or UE2.

In another implementation manner of the present invention, step 201 may further include: receiving an adaptive parameter of the first communications device and/or a media adaptive parameter of the second communications device, sent by the core network device.

The core network may be a Mobility Management Entity (MME) or the like. As shown in FIG. 1a and FIG. 1b, the MME may acquire the media adaptation parameters of the UE1 or the UE2, and then send the parameters to the eNB. In FIG. 1a, the MME obtains the media adaptation parameters of UE1 and/or UE2 and sends them to the eNB. In FIG. 1b, the MME obtains the media adaptation parameters of UE1 and/or UE2 and sends them to eNB1 or eNB2. When transmitting to eNB1, UE1 is the first communication device, and UE2 is the second communication device. Otherwise, when it is sent to eNB2. At the time, UE1 is the second communication device, and UE2 is the first communication device.

202. When it is determined that the media adaptation parameter needs to be adjusted, send a parameter adjustment command, where the parameter adjustment command includes a target media adaptation parameter, where the parameter adjustment command is used to indicate that the media of the communication device is adaptive. The parameters are adjusted to the target media adaptation parameters.

It can be understood that the radio access network device, such as the eNB, can perceive the channel quality in the entire cell, and then confirm whether the media adaptation parameter of the communication device needs to be adjusted according to the perceived channel quality. Therefore, in some embodiments of the present invention, step 202 specifically includes: determining, according to the communication channel information, whether the media adaptation parameter of the communication device needs to be adjusted, and determining that the media adaptation of the communication device needs to be adjusted And sending, by the parameter, the parameter adjustment command, where the communication channel information includes at least one of an air interface packet loss rate, a packet delay, a packet delay jitter frequency, a signal to interference and noise ratio SINR, a channel quality indicator, and a channel load. .

For example, when the packet loss rate and the channel load are greater than a certain threshold, the speech coding rate is adjusted to a lower coding rate; when the speech quality is below a certain threshold, the redundant transmission mode is used to perform the speech frame. Multiple transmissions; considering the efficiency of voice data transmission of small data, it is also possible to adjust the frame aggregation degree of voice packets, and aggregate multiple voice frame data into one voice packet for transmission. Conversely, voice rate can be increased, and redundant transmission and voice packet aggregation can be reduced. It should be noted that the adjustment of the various adaptive parameters may be adjusted by a single parameter or a joint adjustment of multiple parameters. The invention is not specifically limited.

In some embodiments of the present invention, determining, according to the communication channel information, whether the media adaptation parameter of the communication device needs to be adjusted comprises: determining, according to the uplink communication channel information, whether the media of the first communication device needs to be adjusted. Adapting parameters; and/or determining, according to downlink communication channel information, whether media adaptation parameters of the second communication device need to be adjusted; and determining that media adaptation parameters of the first communication device need to be adjusted and/or determining adjustments The parameter adjustment command is sent when the media adaptation parameter of the second communication device.

For example, in FIG. 1a, the UE1 is the first communication device, and sends uplink data. In the eNB, according to the uplink communication channel, it is determined whether the media adaptation parameter of the UE1 needs to be adjusted, and the eNB determines the media of the UE2 according to the downlink communication channel. Adapt to the parameters need to be adjusted. The quality of the downlink channel may be determined according to a measurement report value reported by the UE, such as a Channel Quality Indica (CQI), a Power Headroom Report (PHR), or the like.

It can be seen that, in the embodiment of the present invention, the radio access network device participates in the adjustment of the media adaptive parameter of the communication device, because the radio access network device can directly sense the state of the wireless network, adjust the time, improve the user experience, and Ability to make the most of resources.

Referring to FIG. 3, FIG. 3 is a schematic flowchart of a method for adjusting a media adaptive parameter according to another embodiment of the present invention; as shown in FIG. 3, a method for adjusting a media adaptive parameter may include:

301. The first communication device receives a parameter adjustment command sent by the radio access network device, where the parameter adjustment command includes a target media adaptation parameter of the first communication device, where the parameter adjustment command is used to indicate the first communication. The device adjusts the media adaptation parameter to the target media adaptation parameter, where the media adaptation parameter includes a voice adaptation parameter and/or a video adaptation parameter;

It can be understood that the parameter adjustment command may further include a target media adaptation parameter of the second communication device, and after receiving the parameter adjustment command, the first communication device sends the target of the second communication device to the second communication device Media adaptive parameters.

The first communication device UE1 may adopt the RTCP extension command RTCP_APP or the SDP protocol Session Initiation Protocol (SIP) message format. The target media adaptation parameter is sent to the second communication device UE2.

The first communication device may be UE1 or UE2 in FIG. 1a and FIG. 1b. In FIG. 1a, when the first communication device is UE1, the second communication device is UE2, and the first communication device receives a parameter adjustment command sent by the eNB; When the first communication device is the UE2, the second communication device is the UE1, and the first communication device simultaneously receives the parameter adjustment command from the eNB. In FIG. 1b, when the first communication device is UE1, the second communication device is UE2, and the first communication device receives a parameter adjustment command from eNB1; otherwise, when the first communication device is UE2, the second communication device is UE1. The first communication device receives a parameter adjustment command from the eNB2.

The media adaptation parameter of the first communication device and the media adaptation parameter of the second communication device respectively include a voice adaptive parameter and/or a video adaptive parameter. For details, refer to the voice adaptive parameter in the embodiment of FIG. 2 . And/or introduction of video adaptive parameters.

In some embodiments of the present invention, the first communication device may request the radio access network device to determine whether to adjust the media adaptation parameter. Of course, the radio access network device may also determine according to the radio communication channel quality. Therefore, before the step 301, the method further includes: the first communications device sends a parameter adjustment request to the radio access network device, where the parameter adjustment request is used to request the radio access network device to confirm whether the first adjustment is needed. A media adaptive parameter of a communication device.

Of course, the parameter adjustment request may also include a media adaptation parameter of the second communication device.

In some embodiments of the present invention, before step 301, the first communications device sends a radio resource control RRC message to the radio access network device, where the RRC message carries media adaptation of the first communications device. parameter.

Of course, the RRC message may also carry the media adaptation parameters of the second communication device.

In some other embodiments of the present invention, before step 301, the first communications device sends a media access control MAC message, where the MAC message carries a media adaptation parameter of the first communications device.

Of course, the MAC message can also carry the media adaptation parameters of the second communication device.

In the embodiment of the present invention, the first communication device may send the media adaptation parameter of the self and/or the second communication device to the radio access network device by using an RRC message or a MAC message.

302. The first communications device adjusts a media adaptation parameter to the target media adaptation parameter.

It can be seen that, in the embodiment of the present invention, the first communication device can adjust the media adaptive parameter according to the parameter adjustment command of the radio access network device, so as to avoid the packet loss rate, the air interface delay, and the like by the RTP application layer in the traditional technology. The disadvantages of media adaptive parameter adjustment are to improve the user experience and make full use of wireless resources.

For example, in conjunction with FIG. 1a, the UE1 requests the eNB to adjust the voice packet parameters in the UE1, and sends its own voice packet parameters, including frame aggregation and frame redundancy, where the frame redundancy specifically includes the redundancy level and Redundant offset. For example, the currently used frame aggregation of UE1 is: 01, the redundancy level is: 00, and the redundancy offset is 00; and the parameter adjustment command of the eNB is frame aggregation: 01, redundancy level: 01, and redundancy. The offset is: 01.

First, for frame aggregation, you can use several ways to indicate several aggregation methods:

00, used to indicate that one voice packet includes one voice frame;

01, used to indicate that one voice packet includes two voice frames;

10, used to indicate that one voice packet includes three voice frames;

11, used to indicate that 4 voice frames are included in one voice packet.

The redundancy levels include the following levels:

00, used to indicate that there is no redundancy;

01, used to indicate 100% redundancy, indicating that a voice frame will be sent twice;

10, used to indicate 200% redundancy, indicating that a voice frame will be sent three times;

11, used to indicate 300% redundancy, indicating that a voice frame will be sent four times.

For the redundancy offset, the following offset modes are included:

00, used to indicate that there is no offset;

01, used to indicate that the voice frame transmitted by the redundancy is offset by one voice packet at the time of the last transmission;

10, used to indicate that the redundantly transmitted voice frame is offset by 2 voice packets at the time of the last transmission;

11. It is used to indicate the position where the redundantly transmitted voice frame is offset by 3 voice packets when it is sent last time.

The UE1 has the capability of parsing the foregoing 00, 01, 10, and 11. As shown in FIG. 4a, the current voice packet parameters of the UE1 are frame aggregation: 01, redundancy level: 00, and redundancy offset: 00. The RTP packet mode is shown in Figure 4a. Each RTP packet includes 2 voice frames, with no redundancy or offset. As shown in FIG. 4b, the eNB determines that the UE1 can perform the voice packet by using the RTP grouping mode shown in FIG. 4b according to the quality of the radio channel, and after the UE1 accepts the eNB parameter adjustment command, it will be connected. The package is carried out in the manner of Figure 4b.

If the UE1 uses the grouping mode of FIG. 4b to perform voice grouping, compared with FIG. 4a, the redundancy of the same voice frame can be increased, and the packet loss rate is reduced when the quality of the wireless channel is poor, thereby improving the user experience. .

For example, in combination with FIG. 1a, UE1 performs packet segmentation adjustment in video packet parameters. As shown in FIG. 5a to FIG. 5c, one video frame is divided into multiple RTP packets for transmission in the RTPP application layer. The air interface RLC layer performs segmentation concatenation according to the physical transport block size. Figure 5a shows the parameters of the packet split currently used by UE1, that is, one video frame is divided into two RTP packets according to the size of the Maximum Transmission Unit (MTU) of the IP layer, and Figure 5b shows the eNB according to the wireless air interface. The recommended partitioning method for quality or wireless load status, that is, dividing one video frame into three RTP packets. Thereafter, the eNB again suggests that UE1 divides one video frame into six RTP packets. As can be seen from FIG. 5a to FIG. 5c, one video frame is sequentially divided into two RTP packets, three RTP packets, and six RTP packets. Since an RLC segmentation error will result in an error of the entire upper layer (RTP layer) data packet, the different video frames are divided in the RTP layer, so that the error rate of the video frame is also caused in the case of an error packet loss in the air interface RLC layer. Reduced from the original 1/2 to 1/3 or even 1/6.

It can be seen that, in the embodiment of the present invention, the parameters of the split video frame can be adjusted through the air interface quality, the packet loss rate of the RTP layer of the video frame is reduced, and the user experience is improved.

Specifically, reference may be made to the embodiment shown in Figures 4a to 5c.
