Description
Technical Field
the present invention relates to the field of communications technologies, and in particular, to a data transmission method and apparatus.
Background
in a wireless cellular communication system, the transmission modes of service data can be divided into two types: unicast transmission mode and broadcast transmission mode. For a unicast transmission scheme, for example, in a Physical Downlink Shared Channel (PDSCH) of a Long Term Evolution (Long Term Evolution, LTE) system, a base station (eNB) allocates air interface radio resources to a specific User Equipment (UE) to transmit service data of the UE. For a Broadcast transmission mode, for example, in a point-to-multipoint Traffic Channel (MBMS) for transmitting Evolved Multimedia Broadcast Multicast Service (eMBMS), a Physical Broadcast Channel (PBCH) for a bearer Management Information Base (MIB) in an LTE System, and a Physical Downlink Shared Channel (PDSCH) for a System Information Block (SIB) message, an eNB allocates radio resources for bearer services of all UEs in the entire cell, and a large number of UEs can simultaneously receive Service data by using the Broadcast transmission mode, so that consumption of network transmission resources can be reduced.
However, in the prior art, if the broadcast transmission method is adopted, an operator needs to plan an area and a service in advance and turn on an eMBMS function, so that the broadcast transmission method is adopted for the service set in advance in the area planned in advance. In an area which is not planned in advance, if a high-click and frequent concurrent service exists, a broadcast transmission mode cannot be used, and further, the consumption of network transmission resources is increased.
in summary, the conventional data transmission method cannot flexibly select the data transmission method for different services.

Detailed Description
The embodiment of the invention provides a data transmission method and a data transmission device, which are used for flexibly selecting data transmission modes aiming at different types of services and improving the utilization rate of network resources.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
referring to fig. 1, a data transmission method provided in an embodiment of the present invention includes:
s101, acquiring service request data of at least one UE, and determining service information which is requested to be accessed by the UE according to the service request data of the UE aiming at each UE;
s102, counting the service information which is requested to be accessed by at least one UE according to the service type, and determining the transmission mode corresponding to the services of different types according to the counting result, wherein the transmission mode is a unicast transmission mode or a broadcast transmission mode;
And S103, transmitting the service data of each type according to the transmission mode corresponding to the service of the type aiming at the service of each type.
preferably, in step S101, the service request data of at least one UE is obtained from the eNB, that is, the service request data of the UE sent by the eNB is received. Specifically, the service request Data of the UE may be obtained from the eNB through a user plane S1 interface (S1for the user plane, S1-U) between a Serving Gateway (S-GW) or a packet Data Network Gateway (P-GW) and the eNB.
it can be understood that, the acquiring of the service request data of at least one UE in step S101 is not limited to acquiring the service request data of only one UE, and may be acquiring the service request data of a plurality of UEs. In a specific implementation, for example, each time the eNB receives one service request data packet, the eNB may send the service request data packet, so that, corresponding to step S101, a plurality of service request data packets may be obtained, where the plurality of service request data packets may be sent by different UEs respectively, or may be sent by one UE.
Preferably, for each UE, determining the service information requested to be accessed by the UE according to the service request data of the UE specifically includes:
aiming at each UE, carrying out DPI on service request data of the UE, acquiring a target IP address and a URL (uniform resource locator) of the UE requested to access from the analyzed data, and determining the service type of the UE requested to access according to the target IP address and the URL; and recording the time for performing DPI on the service request data of the UE, and determining the time as the time for using the type of service by the UE.
In the above process, while the target IP address and the URL requested to be accessed by the UE are obtained from the parsed data, a corresponding port number and the like may also be obtained, as shown in fig. 2, where (a) in fig. 2 represents specific information included in the target IP address requested to be accessed by the UE, and (b) in fig. 2 represents a specific presentation format of the target IP address. Therefore, according to the information such as the target IP address, URL, etc., the service type requested to be accessed by the UE can be determined, where the service type may be, for example: video, instant messaging, browsing web pages, etc.
Preferably, for each UE, determining service information requested to be accessed by the UE according to the service request data of the UE, further comprising:
And acquiring the identification information of the UE from the analyzed data. The identification information of the UE may be, for example, an IP address of the UE, an International Mobile Subscriber Identity (IMSI), a radio bearer Identity (APID) corresponding to the UE, and the like.
preferably, the process of acquiring the service request data of the UE further includes: and determining the cell to which the UE belongs by acquiring the source address of the transmission port from the S1-U interface.
preferably, the process of acquiring the service request data of the UE further includes: the eNB receives Signal data of a radio layer of a UE, for example, receives a Common Reference Signal (CRS) of the UE, and determines location information of the UE based on Reference Signal Received Power (RSRP).
Thus, for a certain UE, by determining the service information requested to be accessed by the UE, the related information of the UE, and the like, the following data information list can be formed, as shown in table 1.
TABLE 1
preferably, in step S102, the counting at least one service information that the UE requests to access according to the service type specifically includes:
And for each type of service, counting the time period used by the type of service and the number of the UE using the type of service in the time period.
preferably, the service information requested to be accessed by at least one UE is counted according to the type of the service, for example, the service information requested to be accessed by each UE acquired from the same eNB may be counted. The statistical results can be found in table 2.
TABLE 2
Preferably, in step S102, determining the transmission modes corresponding to the different types of services according to the statistical result specifically includes:
For each type of service, determining the number of UE requesting to access the type of service within a preset time length corresponding to the type of service according to the counted number of UE using the type of service within a time period corresponding to the type of service; and determining the transmission mode corresponding to the type of service according to the number of the UE requesting to access the type of service within the preset time length corresponding to the type of service.
Preferably, the preset duration corresponding to the type of service may be determined according to tolerance of the user to the type of service delay time (i.e., time taken from the user clicking the type of service to presenting the type of service). And the preset time corresponding to the type of service is less than or equal to the time from the user clicking the type of service to the presentation of the type of service.
for example, referring to table 3, assuming that the delay time of the video service that can be tolerated by the user for the video service is 5 to 10s, the preset time duration for the video service should be less than 5s, or within 5 to 10 s; assuming that the delay time of the instant messaging service, which can be endured by a user for the instant messaging service, is 5-30 s, the preset time duration for the instant messaging service should be less than 5s, or within 5-30 s; assuming that the delay time of the web page service, which can be endured by the user for the web page service, is 2-5 s, the preset time duration for the web page service should be less than 2s, or within 2-5 s.
TABLE 3
Preferably, according to the number of UEs requesting to access the service of the type within the preset time period, the transmission mode corresponding to the service of the type is determined in the following manner:
Judging whether the number of the UE requesting to access the type of service in the preset time length is larger than a preset threshold value, if so, determining that the transmission mode corresponding to the type of service is a broadcast transmission mode; otherwise, determining that the transmission mode corresponding to the type of service is a unicast transmission mode.
preferably, in step S103, for each type of service, the transmission of the type of service data according to the transmission mode corresponding to the type of service can be divided into the following two cases:
the first situation is as follows:
for each type of service:
And when the transmission mode corresponding to the type of service is a broadcast transmission mode, sending a service configuration request message aiming at the type to the eMBMS module, and executing transmission of the type of service data by the eMBMS module.
It should be noted that, in the method, the data analysis module may determine transmission modes corresponding to different types of services, so that when it is determined that a transmission mode corresponding to a certain type of service is a broadcast transmission mode, the data analysis module sends a service configuration request message for the type to the eMBMS module, and the eMBMS module performs transmission of service data of the type. The data analysis module and the eMBMS module can be independent devices, so that the transmission of broadcast services (or called eMBMS services) is realized through information interaction between the two devices; the data analysis module and the eMBMS module can also be arranged in one device in a combining mode, and the transmission of broadcast services (or called eMBMS services) is realized through information interaction between the data analysis module and the eMBMS module in the device.
furthermore, it is understood that network elements supporting eMBMS functions are integrated in the eMBMS module, and include, for example: broadcast Multicast Service Center (BM-SC), multimedia Broadcast Multicast Service gateway (MBMS-GW), Mobility Management EntIty (MME), etc., so that transmission of Broadcast services can be completed.
case two:
for each type of service:
and when the transmission mode corresponding to the type of service is a unicast transmission mode, sending the type of service request data to the gateway equipment, and executing the transmission of the type of service data by the gateway equipment.
Here, the gateway device may be an S/P-GW.
Preferably, for each type of traffic: when the transmission mode corresponding to the type of service is a unicast transmission mode, sending the type of service request data to the gateway device, and executing the transmission of the type of service data by the gateway device, wherein the specific process is as follows:
For each type of service:
When the transmission mode corresponding to the type of service is a unicast transmission mode, sending the type of service request data to the eNB, and sending the service request data to the S/P-GW by the eNB, so that the S/P-GW acquires the type of service data from a server and transmits the type of service data; alternatively, the first and second electrodes may be,
and when the transmission mode corresponding to the type of service is a unicast transmission mode, directly sending the type of service request data to the S/P-GW, so that the S/P-GW acquires the type of service data from the server and transmits the type of service data.
preferably, in case one above, for each type of traffic: when the transmission mode corresponding to the type of service is a broadcast transmission mode, the method further comprises the step of sending a service request message aiming at the type to the service agent module, and the service agent module acquires the service information of the type from the server and then sends the service information to the eMBMS module.
That is to say, when the data analysis module determines that the transmission mode corresponding to a certain type of service is a broadcast transmission mode, the data analysis module sends a service configuration request message for the type to the eMBMS module, and sends a service request message for the type to the service agent module, so that the service agent module obtains the service information of the type from the server and sends the service information to the eMBMS module, and after the eMBMS module completes configuration of the type of service, the data analysis module performs transmission of the type of service data according to the service information of the type sent by the service agent module. In the scheme, the data analysis module, the eMBMS module and the service agent module can be respectively set as independent equipment, and then the transmission of the broadcast service is completed through the interaction among the three equipment; or the data analysis module, the eMBMS module and the service agent module may be combined in one device, and the transmission of the broadcast service is completed through interaction among the three modules in the device.
Of course, in a specific implementation, the eMBMS module may also obtain the service information of the type directly from the server without setting the service agent module, and after the eMBMS module completes configuration of the service of the type, the eMBMS module performs transmission of the service data of the type according to the obtained service information of the type. I.e., the functionality of the service broker module is integrated in the eMBMS module.
A specific implementation block diagram of the data transmission method provided by the embodiment of the present invention is given below, as shown in fig. 3.
the system mainly comprises UE, eNB, S/P-GW, a data analysis module, a service agent module, an eMBMS module and the Internet. The Internet may be referred to as a server, and the data analysis module, the service agent module, and the eMBMS module may be integrated in one device.
based on the block diagram shown in fig. 3, the service data transmission process is as follows:
after receiving the service request data sent by each UE, the eNB sends the service request data to the data analysis module through the S1-U interface;
After receiving the service request data sent by the eNB, the data analysis module analyzes and counts the data, which is specifically as follows:
first, DPI is performed on the service request data for each UE received. Determining service information that the UE requests to access, wherein the service information may include: the type of service the UE requests to access (e.g., target IP address, URL, port number, etc.), identification information of the UE (e.g., IP address, etc.), cell ID to which the UE belongs, time for which the UE uses the service, etc. Secondly, for each type of service, the time period used by the type of service and the number of UEs using the type of service in the time period are counted. Finally, aiming at each type of service, judging whether the number of UE requesting to access the type of service in a preset time length corresponding to the type of service is larger than a preset threshold value, if so, determining that a transmission mode corresponding to the type of service is a broadcast transmission mode; otherwise, determining that the transmission mode corresponding to the type of service is a unicast transmission mode.
the above is the judgment process of the data analysis module on the transmission modes corresponding to different types of services, and for each type of service request, the corresponding processing process is as follows:
The first situation is as follows: after determining the transmission mode corresponding to each type of service, the data analysis module sends a service configuration request message for each type of service to the eMBMS module and sends a service request message for each type of service to the service agent module if the transmission mode corresponding to the type of service is a broadcast transmission mode. And after receiving the service request message aiming at the type sent by the data analysis module, the service agent module acquires the service information of the type from the Internet and forwards the service information of the type to the eMBMS module. And the eMBMS module executes transmission of the type of service data according to the service configuration request message aiming at the type sent by the data analysis module and the type of service information sent by the service agent module.
Case two: after determining the transmission mode corresponding to each type of service, the data analysis module sends the received service request data of the UE to the S/P-GW or sends the service request data of the UE to the eNB for each type of service if the transmission mode corresponding to the type of service is a unicast transmission mode, and the eNB forwards the service request data to the S/P-GW. Therefore, the S/P-GW obtains the type of service information from the Interne according to the received service request data and executes the transmission of the type of service data.
