Detailed Description

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

Fig. 1 shows a traffic statistical method of an application according to an embodiment of the present invention, the method including:

s110, responding to the network connection request of the application program, and establishing data connection with the APN for the process of the application program.

When an application component is started and the application has no other running components, the system will create a process containing a single thread for the application program, and certainly, multiple processes can also be created for the application program, however, a component generally corresponds to a process, the identification PID of the process will be recovered by the system after the process is terminated, when the application or a component is opened again, a process will be reallocated, and the identification of the new process is generally larger than the number of the previous identification. After the flow statistics of the process identifier is added, the flow connected with the APN of each application program can be conveniently obtained by combining the flow statistics of the APN.

And according to the requirement, a process can be created for a network module in the application program, when the application program is switched among different APNs, the processes corresponding to the different APNs are different, and therefore the flow of each application program is directly counted according to the process identification PID.

And S120, counting the flow generated by each process through the corresponding APN by using the network connection and management service of the system, so as to determine the flow generated by the application program through each APN.

In the step, on the basis of network connection and management service of the existing system, the flow of each process is acquired by designing and developing an interface for counting the flow under the process identification PID, and further the flow generated by the application program through each APN is acquired.

In a word, the technical scheme can solve the problem that different APN connections are difficult to acquire flow, thereby facilitating subsequent management and charging.

In one or some embodiments, referring to fig. 2 and fig. 3, in the case that the system is Linux or android system, the network connection and management service includes a connection management module (connectivity service), a network management module (network management service), a network policy management module (network policy management service), and a network statistics module (network statistics service), and in order to implement network communication, the android or Linux system further includes a telephone module and a modem or wireless interface layer.

The application or application program is used for providing a certain service function for a user and initiating a network connection request according to a specific APN; the Linux system Kernel is used for taking charge of functions such as network management, a protocol stack, flow statistics and the like; the telephone module Telephony is used for receiving and sending a telephone call, receiving and sending short messages, monitoring a telephone directory, monitoring a network event, reading user information and the like; the modem or Radio Interface Layer (RIL) is responsible for establishing and releasing network connection; and the Network adapter is used for hardware equipment responsible for Network transmission.

Specifically, referring to fig. 2, in the above system, in the presence of multiple APNs, an application needs to connect to a network through the following steps:

firstly, receiving a request for establishing connection, such as a NetworkRequest1, sent by the application program to the connection management module, wherein the number of the NetworkRequest may correspond to the number of the APN; and after receiving the connection request NetworkRequest1, the connection management module judges whether the connection request NetworkRequest1 already exists, and if the NetworkRequest1 is not in the network connection list, the connection management module sends a request for establishing data connection to the telephone module.

And after receiving the request of the data connection, the telephone module sends a request for establishing network connection to the modem or the wireless interface layer.

If the modem or the wireless interface layer successfully establishes network connection, an IP address of a connection network and routing information comprising APN, connection strategy and the like are sequentially returned to the telephone module and the connection management module, and the connection management module transmits the routing information to the network management module and updates the routing information in the kernel of the system through the network management module.

When other application programs exist, a new piece of routing information is established according to the same step, and different application programs can be connected with the network through different APNs at the same time.

In one or some embodiments, the specific steps for implementing the statistics of the traffic generated by the APN according to the process include: firstly, an interface capable of acquiring flow according to a process is developed in a network statistical module, then flow data of the application program and the APN during connection are acquired according to the interface and stored in a virtual file system, and then the flow data are written into a BIN file under a system directory after being read from the virtual file system so as to be called by the system.

According to the schematic structural diagram of utilizing the process identifier to count the traffic interface setting shown in fig. 3, the specific implementation process is as follows:

the network statistics module networkstatservice calls a performPoll function periodically to obtain network transmission statistics information, the performPoll function reads the network statistics information from a file containing network transmission statistics data under a/proc/directory by calling a getnetworkstatsidusiduntail, getnetworksummery and getnetworkstatterother function, converts the network statistics information into a networkstatHistory data structure, stores the networkstatvsservice three hash variables taking the variable of the networkstatkservice type corresponding to the APN and the variable of the uidstatksKey type corresponding to the UID as keys, and calls a writestatstatstatxslot, writenetworkXtlocked, and networkusLocked function according to parameter flag information transmitted by the performPoll to write the corresponding statistics information in the Haspsbind system file (n _ statistics).

Therefore, as the interface for acquiring the flow according to the PID is added in the network statistical module, different process identification PIDs can be set to surf the internet through different routes, and the passing flow is counted.

Specifically, the network type corresponding to the APN is any one of the following types: mobile network Mobile, WiFi, peer-to-peer sharing network BT, Internet, ethernet, virtual network VPN, and hotspot connection services.

In an embodiment, the method further includes a step of performing policy management on APN network connection by using a network policy module, and specifically may include: for each APN, by reading from a policy file (the policy file is stored in a network policy.xml file in a system directory), or by setting a policy setting interface (setnetpolicys and setUidPolicy) provided externally by a network policy manager, the network policy module netpolicymanagervice can control network connection according to the settings or a policy read from the policy file.

In addition, the network strategy module also has the functions of dynamically adjusting the network connection limit and dynamically setting the network connection, the mechanism of dynamically adjusting the network connection limit is to acquire the transmission statistical information of the network connection type matched with the strategy set or read above through the network StatsService service, the network strategy module adopts the network template to match the network connection type, generates effective rules according to the information and submits the rules to the connection management module, and calls the setInterfaceQuota function of the network management module to limit the bandwidth of the network connection.

Therefore, it can be known that at least one of the following controls, including setting on/off of network connection, adjusting network bandwidth connection limit, setting a maximum flow threshold, and the like, can be implemented through interfaces of different network types added in the network policy management module.

For example, the specific steps of setting the maximum flow threshold include: firstly, judging whether the flow of the current process exceeds the maximum flow threshold, if so, sending a network disconnection request to a modem or a wireless interface layer through a telephone service, and then closing the APN corresponding to the process by utilizing the modem or the wireless interface layer.

In one embodiment, the method further includes the step of updating the network connection state in the system kernel, specifically as follows: and after the network connection of the APN is closed, the network management module is informed through the telephone module and the connection management module, and then the network management module is used for updating the network connection state of the APN in the kernel of the system.
