Description

Method and equipment for determining size of data packet
Technical Field
The present invention relates to the field of communications, and in particular, to a method and an apparatus for determining a size of a data packet.
Background
With the development of network technology, mobile data services have also been rapidly developed. Currently, internet manufacturers provide video services to terminals by using telecommunication operator networks, and mobile network broadcasting video services replace televisions occupying the main bodies of mass leisure activities to some extent.
The video playing service of the mobile network is carried out after the user terminal establishes connection with the mobile network, and comprises an initial caching stage and a playing stage. In the initial caching stage, since there is no playable data in the memory of the client, it is necessary to quickly download enough data to start video playing. At present, the initial buffering stage adopts the Transmission Control Protocol (TCP), the Internet Protocol (IP). Because the IP protocol is a single-channel sharing protocol, in order to avoid the reduction of the overall network throughput caused by the collision or error code of a data packet, both communication parties initially adopt tentative transmission, adopt a small initial data packet and try to gradually increase the transmitted data packet for many times until the size of the subsequently transmitted data packet is determined by the occurrence of packet error or collision.
It can be known from the above tentative transmission process that the initial caching period of the mobile network on-demand video service is too long, which results in a long waiting time for the terminal user, and the mobile network on-demand video service cannot exert the maximum performance of the network under the condition that the telecommunication operator network has sufficient bandwidth, which results in a poor experience for the terminal user.
Disclosure of Invention
embodiments of the present invention provide a method and an apparatus for determining a size of a data packet, which evaluate and determine a size of a data packet suitable for a transmission scenario, exert the maximum performance of a network, shorten a data transmission duration, and reduce a user waiting duration.

Acquiring a pre-estimated service rate parameter of the terminal according to the pre-estimated reference parameter; the pre-estimated service rate parameter indicates the pre-estimated service rate which can be supported by the terminal, and the pre-estimated service rate parameter is used for determining the size of a data packet of the resource which is indicated by the identifier and is sent to the terminal.
In a second aspect, an apparatus for determining a packet size is provided, which is configured to perform the method of the first aspect. The equipment specifically comprises:
A receiving unit, configured to receive a service request message sent by a terminal, where the service request message includes an identifier of a resource requested by the terminal;

According to the method and the device for determining the size of the data packet, the pre-estimated service rate parameter for indicating the pre-estimated supportable service rate of the terminal is obtained according to the pre-estimated reference parameter, and then the size of the data packet sent to the terminal is determined according to the pre-estimated service rate parameter. Therefore, the estimated service rate parameter of the terminal can be reasonably controlled as long as the estimated reference parameter is configured in advance according to the actual service scene requirement, and then the data packet size determined according to the estimated service rate parameter is as large as possible on the premise of being suitable for a transmission scene, so that the maximum performance of the network can be exerted through the scheme of the application, the data transmission time length is shortened through the data packet, the waiting time length of a user is shortened as large as possible, and the experience of the terminal user is well improved.

Detailed Description
The terms "system" and "network" are often used interchangeably herein. The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
The basic principle of the application is as follows: the supportable service rate of the terminal is estimated, the size of a data packet which is reasonable and as large as possible is determined according to the estimated service rate parameter of the terminal through the representation of the estimated service rate parameter, so that the maximum performance of a telecommunication mobile network is exerted, the data transmission time length is reduced, and the waiting time length of a user is reduced.
it should be noted that the pre-estimated reference parameter is preset information for evaluating at least one dimension of the pre-estimated service rate parameter of the terminal. The type and content of the pre-estimated reference parameter can be set according to actual requirements, which is not specifically limited in the present application.
For example, the estimated reference parameter may include at least one of the following information:
The current geographical position of the terminal, the current signal quality of the terminal, the performance parameters of the terminal, the load of the terminal access network, and the type of the terminal access network.
it should be noted that the above example is only an exemplary illustration of the type of the estimated reference parameter, and is not a limitation on the type of the estimated reference parameter. In practical applications, any dimension of information used for evaluating the service rate supportable by the terminal can be used as the pre-estimated reference parameter.
the method for determining the size of the data packet provided by the embodiment of the invention can be applied to a service network architecture based on a mobile network shown in fig. 1. As shown in fig. 1, the mobile network-based service network architecture includes a terminal 101 directly interacting with a user, a base station 102 providing mobile network services to the terminal 101, and a target server 103 providing resources to the terminal 101.
The terminal 101 may communicate with the base station 102 directly or with the base station 102 through an access device, which is not specifically limited in this application.
In conjunction with fig. 1, taking a video-on-demand service of a mobile network as an example, an implementation process of the service based on the mobile network is exemplarily described, and the target server 103 is used for providing video resources. Illustratively, the implementation process of the mobile network video service includes: upon receiving a service request from a user, the terminal 101 sends a service request including a requested resource identifier to the target server 103 through the base station 102. When receiving a service request sent by the terminal 101, the base station 102 forwards the received service request to the target server 103 according to the identifier of the target server included in the service request. When receiving the service request, the target server 103 transmits the requested resource to the terminal 101.
In the process of implementing the mobile network video-on-demand service, when the target server 103 transmits the requested resource to the terminal 101, the target server 103 determines the size of the data packet first and then transmits the data packet.
It should be noted that the size of the data packet described in all embodiments of the present application may be an initial data packet size for each service request message response, or may be a size of each data packet in a transmission process for each service request message response.
it should be noted that fig. 1 is only an example to describe an application scenario of the present application. Of course, the scheme of the present application may also be applied to any other scenario for determining the size of the data packet, and is not limited to the scenario of the mobile network video playing service.
the method for determining the size of the data packet provided by the embodiment of the present invention is executed by the apparatus 20 for determining the size of the data packet provided by the embodiment of the present invention. The device 20 for determining the size of the data packet may be deployed alone in a communication link of the network architecture shown in fig. 1, or may also be part or all of the base station 102 in the network architecture shown in fig. 1, or may also be part or all of the target server 103 in the network architecture shown in fig. 1, or the device 20 for determining the size of the data packet may also be deployed as a plurality of devices in the network architecture shown in fig. 1 according to functional modules. The deployment manner of the device 20 for determining the size of the data packet is not specifically limited in the embodiment of the present invention.
fig. 2 is a schematic diagram of the structure of the apparatus 20 for determining the size of a data packet according to the embodiments of the present invention. As shown in fig. 2, the apparatus 20 for determining the packet size may include: processor 201, memory 202, communication port 203.
The following describes in detail the respective constituent elements of the packet size determining apparatus 20 with reference to fig. 2:
The memory 202 may be a volatile memory (hereinafter, referred to as a volatile memory), such as a random-access memory (RAM); or a non-volatile memory (collectively called a non-volatile memory), such as a read-only memory (ROM), a flash memory (collectively called a flash memory), a hard disk (HDD) or a solid-state drive (SSD); or a combination of the above types of memories for storing the relevant applications and configuration files that implement the method of the present invention.
The processor 201 is the control center of the apparatus 20 for determining the size of the data packet, and may be a Central Processing Unit (CPU), A Specific Integrated Circuit (ASIC), or one or more Integrated circuits configured to implement the embodiments of the present invention, such as: one or more microprocessors (DSP), or one or more Field Programmable Gate Arrays (FPGA). The processor 201 may perform various functions of the apparatus 20 for determining the size of a data packet by running or executing software programs and/or modules stored in the memory 202 and invoking data stored in the memory 202.
The communication port 203 may be a transceiving antenna, or an interface for communication with other devices such as a network port.
The specific processor 201 performs the following functions by running or executing software programs and/or modules stored in the memory 202 and calling data stored in the memory 202:
And receiving a service request message sent by the terminal through the communication port 203, wherein the service request message comprises the identification of the resource requested by the terminal. Acquiring a pre-estimated service rate parameter of the terminal according to the pre-estimated reference parameter; the pre-estimated service rate parameter is used for indicating the pre-estimated service rate which can be supported by the terminal; and determining the size of a data packet of the resource which is sent to the terminal and indicated by the identification according to the pre-estimated service rate parameter.
embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
In one aspect, an embodiment of the present invention provides a method for determining a packet size, which is performed by an apparatus for determining a packet size. As shown in fig. 3, the method may include:
S301, receiving a service request message sent by a terminal.
Wherein the service request message includes an identification of the resource requested by the terminal.
specifically, the specific implementation manner of S301 is different according to different deployment locations of devices for determining the size of the data packet, and specifically includes the following two cases:
In the first case, the device for determining the size of the data packet is a network device directly interacting with the terminal, and S301 is implemented to directly receive the service request message sent by the terminal.
for example, in the first case, the device for determining the size of the data packet may be a base station in a mobile network. The base station receives a service request message sent by the terminal through a mobile network.
In the second case, the device for determining the size of the data packet is not a network device directly interacting with the terminal, and S301 is implemented such that the device for determining the size of the data packet receives the service request message forwarded by the network device directly interacting with the terminal.
In both cases, the device interacting directly with the terminal may be a base station in a mobile network, for example. The base station receives a service request message sent by the terminal through a mobile network.
For example, assuming that in the scenario shown in fig. 1, a device for determining the size of a data packet is deployed in the base station 102, S301 is implemented by the first case. Assuming that in the scenario shown in fig. 1, the device for determining the size of the data packet is deployed in the target server 103 or between the base station 102 and the target server 103, S301 is implemented by the second case described above.
S302, acquiring the pre-estimated service rate parameter of the terminal according to the pre-estimated reference parameter.
Specifically, the pre-estimated traffic rate parameter indicates a pre-estimated traffic rate supportable by the terminal. The estimated service rate parameter of the terminal obtained in S302 is used to determine the size of the data packet of the resource that is sent to the terminal and indicated by the identifier.
alternatively, the estimated traffic rate parameter may include the estimated traffic rate itself supportable by the terminal, or the estimated traffic rate parameter may include a parameter corresponding to the estimated traffic rate supportable by the terminal.
illustratively, the parameters corresponding to the predicted traffic rate supportable by the terminal may include signal-to-noise ratio, rate class information, and the like.
it should be noted that all the information that can be used to reflect the predicted terminal-supportable service rate can be used as a parameter corresponding to the predicted terminal-supportable service rate. In practical application, the content of the parameter corresponding to the estimated service rate supportable by the terminal may be determined according to actual requirements, which is not specifically limited in the embodiment of the present invention.
The pre-estimated reference parameter is preset information of at least one dimension used for estimating a pre-estimated service rate parameter of the terminal. The type and content of the pre-estimated reference parameter can be set according to actual requirements, which is not specifically limited in the present application. For example, the estimated reference parameter may include at least one of the following information: the current geographical position of the terminal, the current signal quality of the terminal, the performance parameters of the terminal, the load of the terminal access network, and the type of the terminal access network.
The current geographic location of the terminal may be represented by latitude and longitude, or may be represented by other location parameters, which is not specifically limited in the embodiment of the present invention.
The signal quality of the terminal may be represented by a quality level, may also be represented by a signal amplitude, or may also be represented in other forms, which is not specifically limited in the embodiment of the present invention.
The performance parameter of the terminal refers to a parameter which has an influence on a service rate supported by the terminal from the dimension of the terminal performance. For example, the performance parameter of the terminal may be a screen size of the terminal, or may be a model of the terminal, or may be a processor performance of the terminal, and so on. The embodiment of the invention does not limit the specific content of the performance parameters of the participating terminals.
the load of the terminal access network refers to the load capacity of the network to which the terminal is currently accessed, and is used for reflecting the influence degree of the access network on the service rate of the terminal.
The type of the terminal access network may include information such as a system of the access network. For example, the type of the terminal Access network may be a third Generation mobile communication technology (3 rd-Generation, 3G) network, a Wideband Code Division Multiple Access (WCDMA) network, a Code Division Multiple Access (CDMA) network, or the like. The embodiment of the present invention does not specifically limit the type of the terminal accessing the network.
It should be noted that the above example is only an exemplary illustration of the type of the estimated reference parameter, and is not a limitation on the type of the estimated reference parameter. In practical applications, any dimension of information used for evaluating the service rate supportable by the terminal can be used as the pre-estimated reference parameter.
Further, if the device for determining the size of the data packet can directly obtain the pre-estimated reference parameter, the pre-estimated reference parameter is detected and obtained.
It should be noted that, in all embodiments of the present invention, the embodiment of the present invention is not specifically limited to the process of detecting and acquiring the estimated reference parameter. All the detection modes which can be obtained but can estimate the reference parameters can be applied to the application.
further, if the device for determining the size of the data packet cannot directly obtain the pre-estimated reference parameter, as shown in fig. 4, before performing S302, the method may further include S302 a.
And S302, 302a, receiving the estimated reference parameters.
in S302a, if the device with the determined packet size is the base station, the estimated reference parameters may be directly obtained.
For example, if the device for determining the size of the data packet is deployed in the network architecture shown in fig. 1, at a location other than the base station 102, the estimated reference parameter cannot be directly obtained, and the device for determining the size of the data packet performs S302a to receive the estimated reference parameter sent by the base station 102 before S302.
Further, the process of performing S302 is different according to different contents of the estimated reference parameter. The following describes a specific process of implementing S302 when several estimated reference parameters include the current signal quality of the terminal.
The first implementation process comprises the following steps:
in the first implementation process, in S302, the pre-estimated service rate parameter of the terminal is obtained according to the pre-estimated reference parameter, which may specifically be implemented as step 1 and step 2:
Step 1, searching a preset database according to the current geographic position and the current signal quality of the terminal, and acquiring a service rate parameter corresponding to the current geographic position and the current signal quality in the preset database.
The preset database comprises the statistical distribution of geographic positions, signal quality and service rate parameters.
illustratively, table 1 illustrates a geographic location-related content in a predetermined database. Wherein, the Signal quality is expressed by Reference Signal Receiving Power (RSRP), and the unit is dBm; the rate parameter is expressed in terms of Signal to Interference plus noise Ratio (SINR), which is expressed in dB.
TABLE 1
It should be noted that table 1 only illustrates the content in the preset database and the form of the preset database by way of example, and is not specific limitations on the content in the preset database and the form of the preset database. Further, only the content of the relevant preset database in one geographic location is illustrated in table 1, and the preset database may include the content of the relevant database in at least one geographic location, which is not specifically limited in the embodiment of the present invention.
Specifically, the preset database is a big database which is statistically established according to the historical data of the terminal. When the terminal enters the coverage area of the base station, the geographical position, the signal quality and the supported maximum service rate of the terminal at each moment are recorded, and a statistical distribution database based on the signal quality and the service rate parameters of the geographical position is established for acquiring the estimated service rate parameters of the terminal according to the estimated reference parameters.
The terminal may be a sending terminal of the service request message in S301, or may be another terminal, which is not specifically limited in this embodiment of the present invention.
It should be noted that, as to the establishment manner of the preset database, this is not specifically limited in the embodiment of the present invention. The method can adopt a machine learning modeling mode and a statistical mode, and can be selected according to actual requirements.
further, the preset database may be established by a device that determines the size of the data packet, or may be established by another device, which is not specifically limited in this embodiment of the present invention. The preset database may be stored in the device for determining the size of the data packet, or may be stored outside the device for determining the size of the data packet, which is not specifically limited in the embodiment of the present invention.
And 2, acquiring an estimated service rate parameter of the terminal according to the current geographic position and the service rate parameter corresponding to the current signal quality.
it should be noted that, when the preset database may be stored outside the device for determining the size of the data packet, the preset database may obtain the preset database in an interactive manner to execute S302. Of course, the device for determining the size of the data packet may also transmit the estimated reference parameter to the device for storing the preset database, and the device for storing the preset database performs S302 and then feeds back the result to the device for determining the size of the data packet. That is, S302 may be performed by one device or performed by a plurality of devices in a matching manner, which is not specifically limited in this embodiment of the present invention.
Further, for the step 2, if the estimated reference parameter only includes the current signal quality of the terminal, in the step 2, the service rate parameter corresponding to the current geographic location and the current signal quality is used as the estimated service rate parameter of the terminal.
further, if the estimated reference parameter includes the current load of the terminal accessing the network in addition to the current signal quality of the terminal, the step 2 may be specifically implemented as: and acquiring the estimated service rate parameter of the terminal according to the current geographic position, the service rate parameter corresponding to the current signal quality and the current load of the terminal access network.
it should be noted that, according to the current geographic location and the service rate parameter corresponding to the current signal quality, and the current load of the terminal access network, the specific process of obtaining the estimated service rate parameter of the terminal may be determined according to the actual requirement, and two ways of implementing the process are provided below, but not limited to the specific process.
Optionally, the estimated service rate parameter of the terminal is obtained according to the current geographic location and the service rate parameter corresponding to the current signal quality, and the current load of the terminal access network, which may be specifically implemented by, but not limited to, the following two ways:
The first mode,
And selecting a smaller one of the service rate parameters corresponding to the current geographic position and the current signal quality and the service rate supportable by the terminal corresponding to the current load of the terminal access network as the estimated service rate parameter of the terminal.
The second mode,
And substituting the service rate parameters corresponding to the current geographic position and the current signal quality and the current load of the terminal access network into a preset algorithm to calculate the estimated service rate parameters of the terminal.
It should be noted that, the content of the preset algorithm may be set according to actual requirements, and this is not specifically limited in the embodiment of the present invention. For example, the preset algorithm may be a linear calculation, a power function calculation, or another preset algorithm.
it should be noted that, a specific process of obtaining the estimated service rate parameter of the terminal according to the current geographic location and the service rate parameter corresponding to the current signal quality and the current load of the terminal access network may be specifically determined according to an actual application scenario.
It should be noted that, when the estimated reference parameter includes other parameters besides the current signal quality of the terminal, the process of executing S302 is not repeated here, and may be implemented by referring to the first mode or the second mode, or may be implemented by other modes, which is not specifically limited in this embodiment of the present invention.
Further, in the first implementation process, the process of performing S302 when the estimated reference parameter includes the current signal quality of the terminal is described, and of course, when the estimated reference parameter includes other contents, the process of performing S302 may be similar to or different from that of the first implementation process, and may be set according to actual requirements, which is not specifically limited in this embodiment of the present invention.
the second implementation process comprises the following steps:
In the second implementation process, the obtaining of the pre-estimated service rate parameter of the terminal according to the pre-estimated reference parameter in S302 may specifically be implemented as: and substituting the current signal quality of the terminal, the signal quality of the terminal recorded for the previous N times and the service rate parameter into a preset algorithm to obtain an estimated service rate parameter of the terminal. Wherein N is greater than or equal to 1.
The signal quality and service rate parameters of the terminal recorded for the previous N times refer to parameters of service rates reached by the terminal sending the service request message at different signal qualities recorded before the current time.
It should be noted that, the content of the preset algorithm may be set according to actual requirements, and this is not specifically limited in the embodiment of the present invention. For example, the preset algorithm may be a linear calculation, a power function calculation, or another preset algorithm.
It should be further noted that, for a specific value of N, the value may also be configured according to actual requirements, and this is not specifically limited in the embodiment of the present invention. The larger the value of N is, the more accurate the estimated service rate parameter of the estimated terminal is, but the calculated amount will also increase.
According to the method for determining the size of the data packet, the pre-estimated service rate parameter used for indicating the pre-estimated supportable service rate of the terminal is obtained according to the pre-estimated reference parameter, and then the size of the data packet sent to the terminal is determined according to the pre-estimated service rate parameter. Therefore, the estimated service rate parameter of the terminal can be reasonably controlled as long as the estimated reference parameter is configured in advance according to the actual service scene requirement, and then the data packet size determined according to the estimated service rate parameter is as large as possible on the premise of being suitable for a transmission scene, so that the maximum performance of the network can be exerted through the scheme of the application, the data transmission time length is shortened through the data packet, the waiting time length of a user is shortened as large as possible, and the experience of the terminal user is well improved.
Optionally, after S302, if all functions of the device for determining the size of the data packet are deployed in the target server in the network architecture shown in fig. 1, as shown in fig. 4, the method may further include S303.
S303, the target server determines the size of the data packet of the resource which is sent to the terminal and indicated by the identification according to the estimated service rate parameter.
Specifically, in S303, the size of the data packet of the resource that is sent to the terminal and indicated by the identifier is determined according to the estimated service rate parameter, which may be specifically implemented by any one of the following two implementation manners:
The implementation mode 1,
And determining the data packet size of the resource indicated by the resource identifier included in the service request message sent to the terminal, wherein the data packet size is the data packet size corresponding to the estimated service rate parameter in the preset corresponding relation.
The preset corresponding relation comprises at least one service rate parameter and a data packet size value corresponding to the at least one service rate parameter one to one.
for example, it is assumed that the estimated traffic rate parameter is a traffic rate supportable by the terminal, and is expressed in megabits per second (Mega bit per second, Mb/s), and the corresponding packet size is expressed in megabits (Mega bit, Mb). Table 2 illustrates a preset correspondence.

Pre-estimated traffic rate parameter (traffic rate X) packet size
5≤X＜10 5
10≤X＜20 10
20≤X＜30 20
…… ……
It should be noted that table 1 only describes the content and form of the preset correspondence relationship by way of example, and is not intended to specifically limit the content and form of the preset correspondence relationship.
For example, assuming that the estimated traffic rate parameter is 15Mb/s, the size of the data packet sent to the terminal may be determined to be 10Mb according to the preset correspondence shown in table 1.
