Description

Method, system and related equipment for adjusting media self-adaptive parameters technical field

The present invention relates to the technical field of wireless communication, in particular to a method, system and related equipment for adjusting media self-adaptive parameters.

Background technique

Mobile broadband voice is transmitted from Global System for Mobile Communication (GSM)/Code Division Multiple Access (CDMA)/Universal Mobile Telecommunications (Universal Mobile Telecommunications) on the wireless access network side System, referred to as UMTS) and so on to evolve to LTE. Among them, there have been many solutions for LTE voice. The most commonly used but the fastest growing LTE network is based on the Internet Protocol Multimedia subsystem (IMS). Voice over LTE (VoLTE for short) has become the core network standard architecture in the Internet Protocol (IP for short) era. In the long run, VoLTE can bring value in three aspects: one is to improve wireless spectrum utilization and reduce network costs, and the spectrum utilization is more than four times that of GSM; The communication quality is improved, and the call duration of VoLTE is greatly shortened; the third is that the wireless integration of VoLTE and Rich Communication Suite (RCS for short) can bring more abundant services.

In the VoLTE system, adjustable encoding parameters are provided for voice and video respectively. When in use, the encoding parameters are adjusted by considering the packet loss rate, packet loss burst, initial encoding mode, etc. to achieve voice quality, video quality and system Coordination between capacity, for example, when the network is in a high load state, a lower encoding rate is often used to increase system capacity at the expense of voice quality. In addition, it also provides other adjustable multimedia parameters for voice and video, that is, the parameters used to group packets, such as voice packet rate, frame aggregation, redundancy level and redundancy offset, etc., video packet aggregation, packet Split and interleave etc. Like voice coding parameters and video coding parameters, changes in network transmission capabilities are perceived through Realtime Transport Protocol (RTP)/Realtime Transport Control Protocol (RTCP), such as packet loss at the application layer above. Rate, packet delay, etc., and then adjust the grouping parameters to improve user experience.

When implementing the above group packet parameter adjustment, the terminal uses RTP/RTCP to collect information related to the network. Among them, the terminal cannot accurately identify the quality of the wireless network, and the RTP/RTCP statistical network information and information feedback cycle is long, and the user experience is poor.

201. Acquire media adaptation parameters of the communication device, where the media adaptation parameters include voice adaptation parameters and/or video adaptation parameters;

Wherein, the executor of the embodiment of the present invention is a radio access network device, which may be the aforementioned eNB. The communication device may be a mobile terminal, or a media server, media gateway, etc. with encoding and decoding functions.

It can be understood that the foregoing communication device may include a first communication device and/or a second communication device, such as UE1 and/or UE2 shown in FIG. 1a and FIG. 1b . Therefore, step 201 specifically includes: acquiring the media adaptation parameters of the first communication device, and/or acquiring the media adaptation parameters of the second communication device, where the media adaptation parameters of the first communication device include voice adaptation parameters and/or Video adaptive parameters, the media adaptive parameters of the second communication device include voice adaptive parameters and/or video adaptive parameters.

Wherein, the voice adaptive parameters include voice coding parameters and/or voice group parameters, the video adaptive parameters include video coding parameters and/or video group parameters, and the voice group parameters include frame aggregation and frame redundancy At least one of the video group packet parameters includes at least one of group packet mode (Pack Mode) and group packet type (Packet Type). Frame redundancy includes the redundancy level and redundancy offset described above. Packet mode includes Single Network Abstraction Layer Unit Mode, Non-interleaved Mode and Interleaved Mode; Packet type includes Single Network Abstraction Layer Unit Packet (Single Network Abstraction Layer Unit Packet), Aggregation Packet, Fragmentation Unit Packet.

Among them, the single network abstraction layer unit mode of the packet mode is aimed at the conversation system conforming to the H.241 protocol organized by the International Telecommunication Union Telecommunication Standardization Sector (ITU-T for short); the non-interleaved mode is aimed at It is a session system that does not conform to the H.241 protocol organized by ITU-T. In non-interleaved mode, NAL units are sent in the decoding order of NAL units; interleaved mode is aimed at systems without end-to-end short delay requirements. This mode allows NAL units to be sent in the decoding order of non-NAL units.

A single network abstraction layer unit package in the group package type (refers to encapsulating one NAL unit into one package, that is to say, only one NAL unit is included in the RTP payload; the aggregation package is to aggregate multiple NAL units into 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 one RTP packet, which will help reduce the header ( RTP/UDP/IP) overhead. Currently there are two types type aggregation grouping, including: Single Time Aggregation Group (Single Time Aggregation Group, referred to as STAP) and multi-time aggregation grouping (Much Time Aggregation Group, referred to as MTAP), wherein, in STAP, STAP-A and STAP-B are time-stamped Combined, with the same timestamp in the NAL unit, generally used in low-latency environments. In MTAP, it includes 16-bit offset multi-time aggregation packet (MTAP16) and 24-bit offset multi-time aggregation packet (MTAP24), where different timestamps can also be combined, generally used in high-delay network environments, such as streaming media Application. Its packaging scheme is relatively complicated, but it greatly enhances the performance of H.264 based on streaming media. The split unit packet is to split a NAL unit and use multiple RTP packets for transmission. According to whether it contains the Decoding Order Number (DON for short) domain, it is divided into two types FU-A and FU-B.

It can be understood that, in the embodiment of the present invention, the wireless access network device may confirm whether to adjust the media adaptation parameters of the first communication device or the second communication device, or the first communication device may request wireless access Therefore, in some embodiments of the present invention, before step 201, it also includes: receiving a parameter adjustment request sent by the first communication device, and the parameter adjustment request is used to request confirmation whether the first communication device needs to be adjusted. A media adaptation parameter of the communication device and/or a media adaptation parameter of the second communication device.

Wherein, the radio access network device may obtain the media adaptation parameters of the first communication device or the second communication device from the communication device, and may also obtain the media adaptation parameters of the first communication device or the second communication device from the core network device.

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

As shown in Figures 1a and 1b, the first communication device may be UE1 or UE2. In Figure 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 and UE2 is the second communication device, eNB1 receives the RRC message sent by UE1, and the RRC message includes the media adaptation parameters of UE1 and/or UE2. When UE2 serves as the first communication device, UE2 serves as the first communication device, and eNB2 receives the RRC message sent by UE2, where the RRC message includes media adaptation parameters of UE1 and/or UE2.

In some other implementable manners of the present invention, step 201 may further include: receiving a media access control MAC message sent by the first communication device, the MAC message carrying the first communication A media adaptation parameter of the device and/or a media adaptation parameter 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 and UE2 is the second communication device, eNB1 receives the MAC message sent by UE1, and the MAC message includes the media adaptation parameters of UE1 and/or UE2. When UE2 serves as the first communication device, UE2 serves as the first communication device, and eNB2 receives a MAC message sent by UE2, where the MAC message includes media adaptation parameters of UE1 and/or UE2.

In some other implementable manners of the present invention, step 201 may further include: receiving an adaptation parameter of the first communication device and/or a media adaptation parameter of the second communication device sent by a core network device.

The core network may be a Mobility Management Entity (MME for short), etc., wherein, as shown in Figure 1a and Figure 1b, the MME may obtain the media adaptation parameters of UE1 or UE2, and then send them 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 Figure 1b, the MME acquires the media adaptation parameters of UE1 and/or UE2 and sends them to eNB1 or eNB2. When sending to eNB1, UE1 is the first communication device and UE2 is the second communication device. On the contrary, when sending to eNB2 , 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, and the parameter adjustment command is used to indicate that the media adaptation parameter of the communication device should be adjusted. The parameter is adjusted to the target media adaptation parameter.

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

For example, when the packet loss rate and channel load are greater than a certain threshold, adjust the speech encoding rate to a lower encoding rate; when the speech quality is lower than a certain threshold, use a redundant transmission method for speech frame Send multiple times; considering the efficiency of voice frame data transmission of small data, the frame aggregation degree of voice packets can also be adjusted, and multiple voice frame data can be aggregated into one voice packet for transmission. Conversely, it can increase the voice rate, reduce redundant sending and voice packet aggregation. It should be noted that the adjustment of these various adaptive parameters may be an adjustment of a single parameter, or a joint adjustment of multiple parameters. The present invention is not specifically limited.

In some embodiments of the present invention, the above-mentioned judging whether to adjust the media adaptive parameter of the communication device according to the communication channel information includes: judging whether to adjust the media adaptive parameter of the first communication device according to the uplink communication channel information. adapting parameters; and/or judging whether to adjust the media adaptive parameters of the second communication device according to downlink communication channel information; and determining that the media adaptive parameters of the first communication device need to be adjusted and/or determining the adjustment When the media adaptation parameters of the second communication device are selected, the parameter adjustment command is sent.

For example, in Figure 1a, UE1 is the first communication device and sends uplink data. The eNB judges whether the media adaptation parameters of UE1 need to be adjusted according to the uplink communication channel, and the eNB judges the media adaptation parameters of UE2 according to the downlink communication channel. Whether the adaptation parameters need to be adjusted. The quality of the downlink channel can be judged according to the measurement report value reported by the UE, such as Channel Quality Indicator (CQI for short), Power Headroom Report (PHR for short), etc.

It can be seen that in the embodiment of the present invention, the wireless access network device participates in the adjustment of the media adaptive parameters of the communication device. Since the wireless access network device can directly perceive the status of the wireless network, the adjustment is timely and the user experience is improved. Able to make full use of resources.

Please refer to FIG. 3. FIG. 3 is a schematic flowchart of a method for adjusting media adaptive parameters provided by other embodiments of the present invention; as shown in FIG. 3, a method for adjusting media adaptive parameters may include:

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

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

Wherein, the first communication device UE1 may use the RTCP extension command RTCP_APP mode or the Session Initiation Protocol (Session Initiation Protocol, SIP for short) message form of the SDP protocol to The target media adaptation parameters are 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 the parameter adjustment command sent by the eNB; otherwise , when the first communication device is UE2, the second communication device is UE1, and the first communication device simultaneously receives a parameter adjustment command from the eNB. In Figure 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 eNB2.

Wherein, the media adaptive parameters of the first communication device and the media adaptive parameters of the second communication device respectively include voice adaptive parameters and/or video adaptive parameters, for details, please refer to the voice adaptive parameters in the embodiment of FIG. 2 and/or an introduction to video adaptation parameters.

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

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

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

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

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

Certainly, the MAC message may also carry media adaptation parameters of the second communication device.

Wherein, in the embodiment of the present invention, the first communication device may send the media adaptation parameters of itself and/or the second communication device to the radio access network device through 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 parameters according to the parameter adjustment command of the wireless access network device, so as to avoid the packet loss rate and air interface delay perceived by the RTP application layer in the traditional technology. Disadvantages of media adaptive parameter adjustment, improve user experience, and make full use of wireless resources.

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

First of all, for frame aggregation, the following methods can be used to indicate several aggregation methods:

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

01, used to indicate that 1 voice packet includes 2 voice frames;

10, used to indicate that 1 voice packet includes 3 voice frames;

11, used to indicate that one voice packet includes 4 voice frames.

The redundancy levels include the following levels:

00, used to indicate 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, means that one voice frame will be sent four times.

For redundant offsets, the following offset methods are included:

00, used to indicate no offset;

01, used to indicate the position of the redundantly transmitted voice frame offset by 1 voice packet when it was sent last time;

10. It is used to indicate the position where the redundantly transmitted voice frame was shifted by 2 voice packets when it was sent last time;

11, used to indicate the position of the redundantly transmitted voice frame offset by 3 voice packets when it was sent last time.

UE1 has the ability to parse the above 00, 01, 10 and 11. As shown in Figure 4a, the current voice packet parameters of UE1 are frame aggregation: 01, redundancy level: 00, redundancy offset: 00, and The way of grouping RTP packets is shown in Figure 4a. Each RTP packet includes 2 voice frames without redundancy or offset. As shown in Figure 4b, the eNB determines that UE1 can use the RTP packetization method shown in Figure 4b for voice grouping according to the quality of the wireless channel. After UE1 accepts the eNB parameter adjustment command, it will Next, package in the way shown in Figure 4b.

Among them, if UE1 adopts the grouping method in Figure 4b for voice grouping, compared with Figure 4a, it can reduce the packet loss rate when the wireless channel quality is poor by increasing the redundancy of the same voice frame, thereby improving user experience. .

For another example, please refer to Figure 1a, UE1 adjusts the packet segmentation in the video group packet parameters, as shown in Figure 5a to Figure 5c, a video frame is divided into multiple RTP packets at the RTPP application layer for transmission. The air interface RLC layer performs segment concatenation according to the size of the physical transport block. If Figure 5a shows the packet segmentation parameters currently used by UE1, that is, one video frame is divided into two RTP packets according to the size of the IP layer Maximum Transmission Unit (MTU for short), and Figure 5b shows the eNB according to the wireless air interface The segmentation method recommended by the quality or wireless load status is to divide 1 video frame into 3 RTP packets. Afterwards, the eNB again advises UE1 to divide 1 video frame into 6 RTP packets. It can be seen from FIG. 5a to FIG. 5c that one video frame is divided into two RTP packets, three RTP packets and six RTP packets in sequence. Because an RLC segmentation error will cause the error of the entire upper layer (RTP layer) data packet, different video frame segmentation methods at the RTP layer make the error rate of the video frame 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 video frame segmentation can be adjusted through the quality of the air interface, which reduces the packet loss rate of the RTP layer of the video frame and improves user experience.
