Abstract
The invention provides a method for improving efficiency of upstream video transmission that is supported by a TD-SCDMA system. With further construction and development of the TD-SCDMA system, an HSUPA is gradually put on the agenda. And the HSUPA brings great improvement on upstream lifting of the TD-SCDMA system. With a view of current business development, application relating to video will become one of 3G killer applications and is also one that is different from 2G to the maximum extent. However, because it is uncertain that when wireless propagation environment changes, QoS of video business is substantially influenced. According to the method provided in the invention, a video image processing system can obtain a necessary environmental feature of transmission channel, so that qualities and efficiencies of video/image propagation can be improved.
Description
Technical field
The present invention relates to mobile communication technology, particularly a kind of method of improving efficiency of transmission between communication module and the video monitoring module.
Background technology
What the TD-SCDMA system adopted is time division duplex (TDD) pattern, and physical layer frame structure as shown in Figure 1.According to system performance, TS1 is very flexible to the allocation proportion of these six business time-slots of TS6, and transfer point can be from any one point between TS1～TS6.
Along with 3G business datum business is carried out gradually, the ratio of downlink business necessarily is higher than uplink service, makes the ratio of uplink and downlink timeslot become a present main flow at 2: 4 like this.In this case, if we wish that the TD-SCDMA system can better carry uplink service, especially very high to qos requirement video traffic will fully take into account the problem of system uplink bearing capacity.And this problem is very unconspicuous in the system of FDD standard.
The sampling rate of video monitoring system substantially all is the Several Parameters of preset in advance at present, then regularly according to circumstances/be configured adjustment temporarily, also can't know propagation channel quality information, therefore under the situation of channel generation acute variation, the QoS of monitoring can't be guaranteed.
Summary of the invention
In view of this, the invention provides a kind of method of improving video transmission efficient,, adjust the form and the sampling rate of picture system, improve the efficient and the QoS that improves image of transmission so that video module can in time be known the variation of wireless transmission channel.
Communication module can and video monitoring module between set up the passage of information interaction: can allow video module in time know the environmental change of wireless channel, thereby adjust the sample format and the speed of video.
By technical scheme as can be seen, in the method provided by the invention, defined a kind of new interaction message, by the extracts physical layer parameter, as BLER (error rate), BER (Block Error Rate) or RSCP (received signal code power), RSSI information such as (indications of received signal intensity), estimate the overall target R_phy of present channel; In addition, by extracting the qos parameter R_QoS of reflection service negotiation in the signaling, both are compared:
If R_phy, illustrates then that Channel Transmission is better than previous negotiation parameter greater than R_QoS, according to system requirements, can allow communication module send instruction to video monitoring system, allow it increase the pixel or the frame per second of sampling;
Otherwise, if R_phy, illustrates then that Channel Transmission is worse than previous negotiation parameter less than R_QoS,, can allow communication module send instruction to video monitoring system according to system requirements, allow it reduce the pixel or the frame per second of sampling;

Embodiment
In order to make the purpose, technical solutions and advantages of the present invention clearer, describe the present invention below in conjunction with the drawings and specific embodiments.
The core concept of method provided by the present invention mainly comprises: a kind of method of improving video transmission efficient is provided, so that video module can in time be known the variation of wireless transmission channel, adjust the form and the sampling rate of picture system, improve the efficient and the QoS that improves image of transmission.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being made, is equal to replacement, improvement etc., all should be included within the scope of protection of the invention.
