Description
Technical Field
The invention belongs to the field of computer networks, and particularly relates to a maintenance method and a system for connectivity of storage equipment, a PC (personal computer) end and communication connection.
Background
Android debug bridge (Android Debug Bridge, abbreviated as ADB) is a means for establishing communication connection between Android (Android) equipment and PC (Personal Computer ).
The working principle of ADB is: by listening to ports such as Socket TCP 5554, a communication connection is established between the electronic integrated drive (Integrated Drive Electronics, abbreviated IDE) and Qemu. By default, the ADB will daemon (daemon) on the relevant network port. Thus, when a user runs a program of a type such as Eclipse, the ADB process runs automatically.
If an Android device (such as a mobile phone) and a PC end are to be connected, an ADB driver is required. Specifically, if the mobile phone is to be debugged and managed by a personal computer, an ADB kit needs to be installed in advance.
When a mobile phone and a PC end are establishing a socket-based two-way communication connection to realize passing through the PC end, the mobile phone is usually controlled to serve as a server end (server socket) and the PC end serves as a client end (client socket).
Specifically, in order to establish a communication connection between a mobile phone and a PC terminal based on an ADB socket port, a server terminal needs to run a socket communication program, so that the server terminal constantly monitors the socket port of a certain client terminal, and waits for a connection application of the client terminal to establish a bidirectional communication connection. Therefore, in the communication connection mode based on the socket port, the server side actively waits for the arrival of a connection application.
When a bidirectional communication connection is established by using a socket port, a program at the server side can run a plurality of threads so as to communicate with a plurality of clients simultaneously. And, a plurality of clients can also realize communication connection between each through the server side. The method for establishing the bidirectional communication connection by utilizing the socket port is flexible, so that the method is suitable for some complex communication modes. However, when a bidirectional communication connection is established by using the socket port, the program of the server must be always in an operating state to monitor the socket port of the client.
However, according to long-term experiments of the inventor, it is sometimes required that the PC and the mobile phone are in a long connection state, that is, the communication connection is not interrupted after each operation is completed, so that the data packet is directly transmitted when the next processing is required, and although no data is sent for a long time, the communication connection is maintained; at this time, the program at the server must be always in an operating state to monitor the socket port of the client, and once the program at the server stops operating, the established communication connection is interrupted.
The background art mentioned above is merely technical information held by the inventor for deriving the embodiments of the present invention or learned during the derivation process, and is not necessarily known to the general public prior to the submission of the embodiments of the present invention.

Example 1
In order to avoid that a program in a mobile terminal as a server is always in an operating state to monitor connectivity of communication between a PC and the mobile terminal, in an embodiment of the present invention, a method for maintaining connectivity of a communication connection is provided, where the communication connection is a socket communication connection between the PC and the mobile terminal, as shown in fig. 1, and includes the steps of:
s11, the PC end sequentially and respectively sends detection message packets to each mobile terminal in communication connection with the PC end according to a trigger instruction of a preset trigger mechanism; the preset trigger mechanism comprises generating a trigger instruction at intervals of a preset time period;
taking a mobile terminal as a mobile phone as an example, as shown in fig. 2, a typical application scenario for which the present invention is aimed may be that a PC terminal 20 is connected to a plurality of mobile phones 10 through a USB Hub 30 (USB Hub) to form a multi-mobile phone control system, that is, a user may control a plurality of mobile phones 10 through the PC terminal 20; the PC 20 may be referred to as a client as an execution device controlled by a user, and the mobile phone 10 may be referred to as a server as a controlled device. The inventors have studied and found that in the above-mentioned multi-phone control system, i.e., in the manner of data forwarding connection between the PC terminal 20 and the mobile phone 10 through the USB hub 30, if the control operation is not performed or the access is performed for a long time, the connection between the mobile phone and the PC terminal becomes unstable, which may cause disconnection.
In practical application, the mobile terminal mentioned in the embodiment of the invention can be a mobile phone or other mobile devices such as a PAD.
In the embodiment of the present invention, in order to monitor connectivity with a plurality of mobile phones 10, a typical manner in which a trigger mechanism is preset to generate a trigger instruction is to generate a trigger instruction every other preset period of time by the PC end 20 as a client; in this way, the polling detection of connectivity can be performed once every preset period, and each time of polling detection, a detection message packet needs to be sent to each mobile phone 10 in turn; in general, the probe packet may be a null packet including only a header, or may be a very small packet including some other content (e.g., hello message), where the content of the probe packet is not specifically limited.
Further, in the embodiment of the present invention, the trigger instruction may be generated in other manners, for example, the preset trigger mechanism may further include receiving an alarm signal from the receiver of the PC side 20, and triggering the polling detection of connectivity by using the alarm signal as the trigger instruction. In the embodiment of the present invention, the alarm signal is generated by the voltage monitoring module in the USB hub 30, that is, in the embodiment of the present invention, the voltage detecting module may be provided in the USB hub 30 to monitor the voltage data of the USB hub 30 in real time, so that when the voltage fluctuation value of the USB hub 30 exceeds the preset value, an alarm message may be generated, and in the embodiment of the present invention, the alarm message may be used as a trigger command. The alarm information may be transmitted to the PC 20 through a receiver (USB interface) of the PC 20, so that a preset trigger mechanism may generate a trigger command to trigger the polling detection of connectivity.
The inventor finds that a part of the connection interruption between the PC end 20 and the mobile phone 10 is caused by the instability of the voltage of the USB hub 30; for example, the voltage instability may eventually cause the server to exit the process, which may cause the connection between the PC 20 and the handset 10 to be disconnected. For this reason, in the embodiment of the present invention, the voltage of the USB hub 30 is monitored in real time, so that when the voltage fluctuation is too large, a polling probe can be timely performed to detect whether there is a disconnection of the mobile terminal 10.
S12, the PC terminal starts a corresponding timer for each mobile terminal receiving the message detection packet while sending the detection message packet, wherein the timer is set with a preset time limit;
in the embodiment of the present invention, the PC end 20 starts a timer for each mobile phone 10 while sending a probe message packet to the mobile phone 10, where the timer is set with a preset time limit, that is, starts a timer for the receiving object of each probe message packet; in practical applications, the preset time limit may be set by those skilled in the art according to the duration of the feedback period of the message, for example, the preset time limit may be the duration of one feedback period or the durations of multiple feedback periods.
For example, when the PC end 20 sends a probe packet to the mobile phone 11, the timer 11 is started (the timer 11 is an identifier of the timer), and the timer 11 corresponds to the mobile phone 11; the PC sends a probe packet to the mobile phone 12, and then starts the timer 12 (similarly, the timer 12 is the identifier of the timer), and the timer 12 corresponds to the mobile phone 12. With this push, each handset has a corresponding timer.
S13, deleting the timer when the PC receives a response packet fed back by the mobile terminal corresponding to the timer within a preset time limit of the timer; the response packet is a message packet for the mobile terminal to respond to the detection message packet;
if the connectivity between the PC end and the mobile phone is not problematic, the mobile phone will receive the detection message packet from the PC end, so that the mobile phone can timely feed back the corresponding response packet to the PC end.
That is, the PC end determines whether the connectivity with the mobile phone is normal by receiving the response packet within the preset time limit, and when the PC end receives the response packet within the preset time limit, it means that the mobile phone corresponding to the timer is normally connected with the PC end and is in an active state.
For example, after receiving the probe message packet, the mobile phone 11 feeds back a response packet to the PC; when the timer 11 reaches the preset time limit, the PC side receives the response packet of the mobile phone (mobile phone 11) corresponding to the timer 11, and then the PC side knows that the connectivity with the mobile phone 11 is in a normal state, and can delete the timer 11.
And S14, when the timing of the certain timer exceeds the preset time limit, the PC end sends a request for establishing socket communication connection to the mobile terminal corresponding to the timer.
If a certain timer exceeds a preset time limit and is not deleted, the PC end does not receive a response packet of the mobile phone corresponding to the timer within the preset time limit, and then the communication between the mobile phone and the PC end is interrupted, and at the moment, the connection with the mobile phone needs to be reestablished timely.
For example, since the communication connection between the mobile phone 12 and the PC end is interrupted, the probe packet cannot be received, and thus the response packet cannot be timely fed back to the PC end, which causes the timer 12 to exceed a preset time limit, and the PC end determines that the communication connection with the mobile phone 12 is interrupted; in this way, the connectivity between the PC and the handset 12 can be maintained by reestablishing the connection with the handset 12 in time.
Further, in the embodiment of the present invention, the inventor has found that it is appropriate to set the selection range of the preset period to 4 to 6 seconds; with this interval (4 seconds), it is not only possible to discover the interruption and reestablish the connection in a timely manner, but also the increased network load has less impact on the system performance.
In summary, in the embodiment of the present invention, the PC side is simultaneously connected to a plurality of mobile terminals in communication, and may sequentially send probe message packets to all mobile terminals that establish socket communication with the PC side; while sending each detection message packet, starting a corresponding timer for a receiving object of the detection message packet (namely, a mobile terminal receiving the detection message packet); among a plurality of mobile terminals serving as receiving terminals, if a certain mobile terminal is in a state of communicating with a PC terminal and is active, the detection message packet is received; at this time, the mobile terminal may indicate to the PC that the communication connection between the mobile terminal and the PC is in an active state by feeding back the response packet in time (i.e., within a preset time limit of the timer). When the communication connection between a certain mobile terminal and the PC end is interrupted, the detection message packet cannot be received, and the response packet cannot be fed back to the PC end naturally, so that a timer corresponding to the mobile terminal exceeds a preset time limit; at this time, the PC side can learn that the mobile terminal corresponding to the timer has been interrupted, and then, by sending a communication connection request to the mobile terminal having been interrupted, the connectivity of the communication connection between the PC side and the mobile terminal can be recovered in time.
In the embodiment of the invention, the communication connection between the PC end and the mobile terminal can timely resume the interrupted communication connection by sending the detection message packet and receiving the response packet, so that a program in the mobile terminal serving as a server end is not required to be always in an operation state so as to monitor the socket port of the client end to monitor the communication connectivity between the PC end and the mobile terminal.

starting a corresponding timer for each mobile terminal receiving the message detection packet while sending the detection message packet, wherein the timer is set with a preset time limit;
when a response packet fed back by the mobile terminal corresponding to a timer is received within a preset time limit of the timer, deleting the timer;
and when the timing of the certain timer exceeds the preset time limit, sending a request for establishing socket communication connection to the mobile terminal corresponding to the timer.

When the communication connection between a certain mobile terminal and the PC end is interrupted, the detection message packet cannot be received, and the response packet cannot be fed back to the PC end naturally, so that a timer corresponding to the mobile terminal exceeds a preset time limit; at this time, the PC side can learn that the mobile terminal corresponding to the timer has been interrupted, and then, by sending a communication connection request to the mobile terminal having been interrupted, the connectivity of the communication connection between the PC side and the mobile terminal can be recovered in time.
In the embodiment of the invention, the communication connection between the PC end and the mobile terminal can timely resume the interrupted communication connection by continuously sending the detection message packet and receiving the response packet, so that a program in the mobile terminal serving as a server end is not required to be always in an operation state so as to monitor the socket port of the client end to monitor the communication connectivity between the PC end and the mobile terminal.
