Description
Technical Field
The present application relates to the field of information technology, and in particular, to a data transmission method and a data transmission apparatus.
Background
With the progress of technology, the types and the number of intelligent terminal devices are continuously increased, and the types of mobile services are more and more diversified. Currently, most intelligent terminals have the ability to concurrently and concurrently transmit multiple types of data traffic, such as voice, video, and data. The diversity of massive terminal equipment and service traffic brings convenience to work and life of people, but different service traffic has different resource consumption, and great challenges are brought to performance optimization and user experience of a wireless access network side (base station).
Generally, after receiving service data sent by a server, a base station schedules corresponding resources and forwards the service data to a terminal device in real time. However, most mobile service data has low requirements for real-time performance, and if air interface resources are scheduled once every data packet, the utilization rate of the air interface resources will be reduced, which causes resource waste. Taking LTE as an example, because the scheduling of LTE is performed according to 1ms, the scheduling resources include PDCCH (Physical Downlink control Channel) resources and PDSCH (Physical Downlink shared Channel) resources, and each scheduling needs to occupy PDCCH resources, which would cause PDCCH resource waste accordingly. In addition, because the data packets of different service data have large differences, there is a possibility that the data scheduled at a certain time cannot fill up 1 PRB (Physical Resource Block), which also causes waste of PRB resources. Severely, the perception of the user is also affected.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
Referring to fig. 1, a flowchart illustrating steps of a first embodiment of a data transmission method according to the present application is shown, which may specifically include the following steps:
in the embodiment of the present application, the downlink mobile service data may be any type of service data transmitted to the terminal by the server, for example, voice service data, video service data, and instant message service data (IM) represented by QQ and wechat, and the like.
Generally, when the server sends the mobile service data to the terminal, the server needs to forward the mobile service data through the base station, and therefore, in this embodiment of the present application, the base station can first receive the downlink mobile service data.
in terms of service models such as QQ, WeChat, and browsing web pages, data packets of such services are not only small but also very dispersed, and in terms of resource scheduling, if an air interface resource is scheduled once for each small data packet, the overhead of PDCCH and PRB resources will be wasted under the condition that the number of users in a cell is large, and further the utilization rate of the air interface resource is reduced. Therefore, in this embodiment of the present application, after receiving downlink mobile service data, the base station may first determine whether the downlink mobile service data is packet service data, if so, may continue to perform step 103, and if not, may directly send the data to the user equipment. Fig. 2 is a schematic diagram of a method for data transmission according to the present application.
In the prior art, there are various mature technologies that can identify packet service data, such as a packet detection algorithm, and a person skilled in the art can select a corresponding method according to actual needs to identify received mobile service data to determine whether the mobile service data is packet service data, which is not specifically limited in this application. As an example of the embodiment of the present application, the step of determining whether the downlink mobile service data is packet service data may specifically include the following sub-steps:
a substep of obtaining the data packet length of the downlink mobile service data;
and the substep of judging whether the length of the data packet is greater than a first preset threshold value, and if not, determining that the downlink mobile service data is packet service data.
Specifically, the base station may first obtain a data packet length of the received downlink mobile service data, and then compare the data packet length with a preset first threshold, thereby identifying whether the data is packet service data.
Generally, data having a packet length of less than 100 bytes or 200 bytes can be regarded as packet service data.
generally, the specified location may be the L2 layer of the base station, and more particularly, the PDCP layer of the base station. The PDCP (Packet Data Convergence Protocol) layer belongs to a second layer of a radio interface Protocol stack, and is used to process radio resource management (RRC) messages on a control plane and Internet Protocol (IP) packets on a user plane. On the user plane, after the PDCP sublayer obtains an IP data packet from an upper layer, it may perform header compression and ciphering on the IP data packet, and then deliver it to an rlc (radio Link control) sublayer. In the control plane, the PDCP sublayer provides signaling transport services for the upper RRC layer, and implements ciphering and consistency protection of RRC signaling, and implements deciphering and consistency checking of RRC signaling in the reverse direction.
In this embodiment of the present application, after packet service data is identified, the packet service data may be cached to a PDCP layer of a base station, so as to perform data packet convergence of a service plane.
104, monitoring the buffer amount and/or the time delay value of the cached packet service data in real time;
in the embodiment of the application, after a certain type of packet service data is cached, the data can be monitored in real time to obtain the delay value of the type of data and the total data amount cached by the PDCP layer. In general, a data latency value may refer to a time calculated from when data is received and buffered at a base station side.
And 105, sending the cached packet service data to user equipment according to the caching amount and/or the time delay value.
In a specific implementation, when the total data amount cached by the base station PDCP layer exceeds a certain preset threshold, resources can be scheduled, and all cached packet service data is sent to the user equipment; or, when the delay value of a certain type of packet service data exceeds a preset threshold, the buffered packet service data of the type may be sent to the user equipment.
In the embodiment of the application, when the received downlink mobile service data is judged to be packet service data, the packet service data is cached to the PDCP layer of the base station, and then resources are scheduled when the cached data volume or the time delay value of the data exceeds the preset threshold value, and the cached data is sent to the user equipment, so that the problem that one-time empty resource is required to be scheduled when a data packet arrives every time is avoided, and the bearing efficiency of PRB resources and the scheduling efficiency of PDCCH resources are effectively improved.
Referring to fig. 3, a flowchart illustrating steps of a second embodiment of the data transmission method of the present application is shown, which may specifically include the following steps:
in the embodiment of the present application, the downlink mobile service data may be any type of service data transmitted to the terminal by the server, for example, voice service data, video service data, and instant message service data (IM) represented by QQ and wechat, and the like.
in a specific implementation, a base station may first obtain a packet length of received downlink mobile service data, and then compare the packet length with a preset first threshold, so as to identify whether the data is packet service data, if so, step 303 may be continuously performed, and if not, the data may be directly sent to a user equipment.
For example, if the first preset threshold is set to 150 bytes, when the length of the received data packet is 100 bytes, the data packet can be considered as packet service data. The specific value of the first preset threshold can be determined by those skilled in the art according to actual needs, and the application is not limited to this specific value.
in the embodiment of the application, after the packet service data is identified, whether the packet service data is a ping packet or a response packet of the ping packet can be continuously judged.
ping is a command under Windows, Unix and Linux systems, and also belongs to a communication protocol, and is a part of a TCP/IP protocol. Generally, ping service is sensitive to delay and needs to be processed separately, if the small packet of service data is not a ping packet or a response packet of a ping packet, step 304 may be executed to cache the data to a specified location, and if the small packet of service data is a ping packet or a response packet of a ping packet, the ping packet or the response packet of a ping packet needs to be sent to a user equipment in real time.
In a preferred embodiment of the present application, the step of determining whether the packet service data is a ping packet or a response packet of a ping packet may specifically include the following sub-steps:
a substep of obtaining a data packet header of the small packet service data;
and a substep of analyzing the data packet header to determine whether the small packet service data is a ping packet or a response packet of the ping packet.
Generally, the packet header contains a corresponding identifier, and by identifying the identifier, it can be determined what type of data the data is. Therefore, in this embodiment of the application, when determining whether the packet service data is a ping packet or a response packet of a ping packet, the packet header of the packet service data may be acquired, and the packet header is analyzed to determine whether the data is a ping packet or a response packet of a ping packet.
in the embodiment of the present application, the specified location may be a PDCP layer of a base station.
in the embodiment of the application, after a certain type of packet service data is cached, the data can be monitored in real time to obtain the delay value of the type of data and the total data amount cached by the PDCP layer. In general, a data latency value may refer to a time calculated from when data is received and buffered at a base station side.
It should be noted that, for different types of data, the delay value needs to be monitored separately, and for the data buffering amount, only the total data amount buffered by the PDCP layer may be monitored.
generally, the configuration of the data buffering amount threshold, i.e. the first preset threshold, mainly considers that no waste of air interface PRB resources is caused, which is related to the MCS (Modulation and Coding Scheme, Modulation and Coding strategy) level of the user, and considering according to the granularity of scheduling 1 minimum PRB, the TBSize (i.e. the size of the transport block scheduled by 1 ms) that can be scheduled by different MCS levels is different, so that this value can be used as the first preset threshold, and different buffered data amount thresholds can be provided according to different current MCS levels of the user.
The threshold of the Delay value, that is, the second preset threshold, mainly considers user perception, different QCIs (QoS identifiers, QoS class identifiers) correspond to different PDBs (Packet Delay budgets) with maximum transmission Delay, and considering that the scheduling time of the base station and retransmission possibly caused by an air interface environment may generally suggest that the value is 1/2 of the PDB value, and for different QCIs, the configured second preset thresholds may be different.
In the embodiment of the application, after the packet service data is identified, whether the packet service data is a ping packet or a response packet of the ping packet can be further determined, if so, the response packet of the ping packet or the ping packet is sent to the user equipment in real time, and if not, the data packet is cached to the designated position of the base station, so that data of service types with higher requirements on real-time performance, such as ping service, can be sent to the user equipment in time, and under the condition of effectively improving the utilization rate of air interface resources, the real-time transmission of special service data is ensured.
