As shown in fig. 1, an embodiment of the present invention provides an information transmission method, which may include the steps of:
step 11: a target data radio bearer DRB for transmitting the traffic data stream is determined.
Wherein, the target DRB is: a first DRB with compression capability or a second DRB without compression capability.
Preferably, step 11 comprises: and establishing a first DRB and a second DRB between the terminal and the network equipment, and determining a target DRB from the first DRB and the second DRB according to the type of the service data flow. For example, a plurality of DRB bearers are established between the terminal and the network device, and for example, the plurality of DRB bearers include DRB1 with compression capability and DRB2 without uplink compression capability.
Wherein the first DRB comprises at least two DRBs with different compression algorithms; the second DRB includes at least one DRB. The compression algorithm comprises a header compression algorithm and a data compression algorithm. Header compression algorithms include, but are not limited to: IP header compression (IP Header Compression, IPHC) algorithms, compression IP/UDP/RTP header (CRTP) algorithms, compression TCP/IP header (CTCP) algorithms, robust header compression (Robust Header Compression, roHC) algorithms, and the like. Data compression algorithms include, but are not limited to, upstream data compression (Uplink Data Compression, UDC) algorithms, and the like. When there are a plurality of DRBs having compression capability, the compression algorithm used for each DRB is different, for example, DRB1' uses an uplink RoHC compression algorithm, and DRB1 "uses a UDC compression algorithm.
Step 22: and transmitting the service data stream through the target DRB.
After determining a target DRB according to the type of the service data stream to be transmitted, the service data stream is transmitted through the target DRB, so that according to different types of the service data stream, whether the target DRB for transmitting the service data stream is a first DRB with compression capability or a second DRB without compression capability is determined, the service data stream can be ensured to be matched to the most suitable DRB, and the data transmission efficiency is improved to the greatest extent on the premise of ensuring that the power consumption of a terminal is not influenced.
In a preferred embodiment, the step of determining the target DRB from the first DRB and the second DRB according to the type of traffic data flow includes, but is not limited to, the following scenarios:
when the service data stream is a first type data stream, determining a first DRB as a target DRB; wherein the first type of data stream is a persistent data stream. That is, when the traffic data stream is a persistent data stream, the first DRB having compression capability is determined as the target DRB. Wherein the persistent data stream includes, but is not limited to: uploading and downloading files, downloading downlink video streams, web browsing and the like. In the above example, the service data stream using the first DRB with the uplink compression capability may be a persistent uplink data stream (such as file upload and download, downlink video stream, web browsing, etc.).
Preferably, the step of determining the first DRB as the target DRB comprises: and determining the DRB with specific compression capability in the first DRB as a target DRB according to the header duty ratio in the data packet corresponding to the service data flow. The compression algorithm comprises a header compression algorithm and a data compression algorithm, and the compression capacities achieved by the different compression algorithms are different, so that the DRB adopting the proper compression algorithm is selected as the target DRB according to the header duty ratio in the data packet corresponding to the service data flow. Wherein the header duty cycle may be: the size ratio of the header to the data portion, or the size ratio of the header to the entire data packet.
Specifically, when the header ratio in a data packet corresponding to the service data flow exceeds a preset proportion, determining a DRB adopting a first compression algorithm in the first DRB as a target DRB; wherein the first compression algorithm comprises: header compression algorithm. That is, when the header ratio in the data packet corresponding to the service data flow exceeds the preset ratio, the header compression space in the data packet is indicated to be larger, and the DRB adopting the header compression algorithm in the first DRB is determined as the target DRB. When the header ratio in the data packet corresponding to the service data flow is lower than a preset ratio, determining the DRB adopting a second compression algorithm in the first DRB as the target DRB, wherein the second compression algorithm comprises: a data compression algorithm. That is, when the header ratio in the data packet corresponding to the service data flow is lower than the preset ratio, the compression space of the data portion in the data packet is larger, and the DRB adopting the data compression algorithm in the first DRB is determined as the target DRB. For example: and continuously upstream (such as voice or video data) judging according to the header ratio of TCP/IP data in an upstream data packet, wherein the upstream data packet is used for applying DRB of an upstream RoHC algorithm when the TCP/IP data header ratio exceeds a certain ratio, and otherwise, applying DRB of an upstream UDC algorithm.
Or in the second mode, the step of determining the target DRB from the first DRB and the second DRB according to the type of the service data flow includes: and when the service data stream is the second type data stream, determining the second DRB as a target DRB. Wherein the second type of data stream is a non-persistent data stream. That is, when the traffic data stream is a non-persistent data stream, the second DRB having no compression capability is determined as the target DRB. Wherein the non-persistent data stream includes, but is not limited to: voice or video data. In the above example, if the uplink traffic data stream is voice or video data, the non-compression mode should be adopted, that is, the second DRB without compression capability is adopted.
In a preferred embodiment, the step of determining the target DRB from the first DRB and the second DRB further comprises, depending on the type of traffic data flow: and identifying the type of the service data stream through a preset characteristic file. Taking uplink transmission as an example, the type (or called protocol feature) of the uplink traffic data stream can be identified quickly by performing feature matching through a preset feature file.
Further, the specific implementation manner of step 11 may further include, in addition to the manners described in the first scenario and the second scenario, the following manners in the scenarios:
scene III: when the type of the service data stream cannot be identified through the preset feature file, one of the first DRB and the second DRB is determined to be a target DRB, and matching efficiency evaluation is carried out to obtain a corresponding first evaluation value; if the first evaluation value meets the preset requirement, one of the first DRB and the second DRB is determined to be a target DRB; if the first evaluation value does not meet the preset requirement, determining the other one of the first DRB and the second DRB as a target DRB, and evaluating the matching efficiency to obtain a corresponding second evaluation value; if the second evaluation value meets the preset requirement, determining the other one of the first DRB and the second DRB as a target DRB; and if the second evaluation value does not meet the preset requirement, determining the target DRB according to the first evaluation value and the second evaluation value.
The scene is a processing mode for the protocol characteristics of the service data flow which can not be identified: the first mode is that the business data stream is led into the first DRB with compression capability to carry out uplink compression, the adaptive effect is judged through the feedback matching efficiency evaluation value (or called compression efficiency evaluation value), if the adaptive effect does not meet the preset requirement, the business data stream is led into the second DRB without compression capability, the adaptive effect is judged through the feedback matching efficiency evaluation value, and if the adaptive effect still does not meet the preset requirement, the best adaptive effect in the evaluation is taken as the target DRB.
Alternatively, a second approach may also be used for this scenario: and directly importing the service data stream into a second DRB which does not have the compression capability for transmission, and carrying out subsequent processing by updating a rule preset characteristic file.
Preferably, after step 11, further comprising: performing matching efficiency evaluation on the target DRB to obtain a corresponding third evaluation value; if the third evaluation value does not meet the preset threshold requirement, prompting that the target DRB is not matched with the service data flow. The traffic data stream is directed to the most matched target DRBs in the manner described above but not limited thereto, and each target DRB compresses the corresponding traffic data stream according to its compression algorithm. Each target DRB performs dynamic statistical calculation on compression efficiency, meanwhile, divides a network environment into a plurality of ranges, and can introduce different minimum compression efficiency threshold limits for uplink data streams of a specific type according to different network environments, if the compression efficiency is lower than the minimum threshold, the target DRB is prompted to be unsuitable for the service data stream of the type, so that the target DRB can be set to be unsuitable for the compression type of the service data stream of the type and fed back to a judging module for identifying the service data stream through a preset feature file, and dynamic updating and adjustment of the preset feature file are realized.
As shown in fig. 2, the architecture of information transmission according to an embodiment of the present invention may include: the method comprises the steps of identifying a judging module of the type of a service data stream through a preset characteristic file, a first DRB with compression capability, a second DRB without compression capability, and an evaluating module for evaluating the matching efficiency of different DRBs in the first DRB. Wherein the first DRB comprises a DRB that employs compression algorithm 1, wherein n is a positive integer. A plurality of DRBs are established between the terminal and the network equipment, and the DRBs comprise: a first DRB and a second DRB. And dynamically and intelligently identifying uplink and downlink service data streams through a judging module for identifying the type of the service data stream, and guiding the proper service data stream to the most matched target DRB, so that the uplink and downlink transmission efficiency is improved to the maximum extent on the premise of ensuring that the power consumption of the equipment is not influenced. In addition, each DRB is subjected to matching efficiency (or compression efficiency) evaluation, and the evaluation result is fed back to the judgment module, so that dynamic updating and adjustment of the preset characteristic file in the judgment module are realized.
In the information transmission method of the embodiment of the invention, the terminal or the network equipment determines whether the target DRB for transmitting the service data stream is the first DRB with the compression capability or the second DRB without the compression capability according to different types of the service data stream, so that the service data stream can be ensured to be matched with the most suitable DRB, and the data transmission efficiency is improved to the maximum extent on the premise of ensuring that the power consumption of the terminal is not influenced.
