Because the portable broadband wireless device does not need to be powered off and the charge card installed in the modem does not need to be replaced, the network can realize switching of network signals without long-time disconnection, and the purpose of providing continuous network signals is realized. Meanwhile, the portable broadband wireless device disclosed by the embodiment can not only provide network signals for the mobile equipment, but also charge the mobile equipment in real time as a mobile charging device.
The invention discloses a network signal switching method, which is applied to a portable broadband wireless device disclosed in the embodiment, and referring to fig. 2, the embodiment comprises the following steps:
s201, after receiving a network signal switching command, acquiring parameter information of a network signal connected with at least one modem in the plurality of modems;
although the portable broadband wireless device has a plurality of modems, each of which can be connected to a network signal, the portable broadband wireless device uses only the network signal of one modem at the same time, and provides the network signal connected to the modem to each mobile device as a shared network signal. The shared network signal can be used by each mobile device by logging in to the wireless account provided by the portable broadband wireless device.
In some specific scenarios, for example, when a high bandwidth is required to ensure fluency in live broadcasting, and when the bandwidth of the shared network signal provided by the portable broadband wireless device cannot meet the live broadcasting fluency, the user may think of switching the network signal to which the mobile device has been connected. Alternatively, the network traffic that can be provided by the tariff card inserted into the modem is limited, and when the network traffic provided by one tariff card runs out, the network signal connected to the tariff card needs to be switched.
And acquiring parameter information of the network signal connected with at least one modem in the plurality of modems after receiving the network signal switching command based on any requirement.
The specific acquisition mode is as follows: the method comprises the steps of sending a parameter request command to at least one modem and receiving parameter information returned by each modem responding to the parameter request command.
The parameter information is used to determine the state of the network signal, such as bandwidth information, but may also include other information related to the current network state. The present embodiment does not limit the specific content of the parameter information.
The modem responds to the parameter request command only after receiving the parameter request command, namely feeding back the parameter information of the network signal connected with the modem. The received parameter information is not parameter information of network signals of all modem connections but only parameter information of network signals of modem connections for which the parameter request command is received.
Optionally, after receiving the network signal switching command, parameter information of the network signal connected to each of the plurality of modems is obtained. Based on the network signal with the best network signal state in all the network signals, the network signal with the best network signal state can be determined, and the network signal with the best state can be conveniently used as a shared network signal subsequently, so that the mobile device can be connected with a network by using the network signal with the best state.
Optionally, after receiving the network signal switching command, acquiring parameter information of the network signal connected to any two modems of the plurality of modems. Based on the method, the states of any two network signals can be rapidly acquired, so that the network signal with a good network state can be rapidly taken as the shared network information, and the purpose of rapidly switching the network signal is further realized.
S202, determining a network signal according with a preset rule according to the parameter information;
the preset rules include highest bandwidth, maximum throughput, minimum delay, etc.
Different preset rules can be selected when the parameter information is different, for example, if the parameter information is bandwidth information, the preset rule is the highest bandwidth, and then the network signal with the highest bandwidth can be determined;
if the parameter information is time delay information, the preset rule is that the time delay is minimum, and then the network signal with the minimum time delay can be determined.
It is understood that the parameter information may include a plurality of contents, for example, the parameter information includes bandwidth information and delay information, and the preset rule is a maximum value of the bandwidth information multiplied by a bandwidth weight and the delay information multiplied by a delay weight.
After the step, the network signal with the best network state can be determined from a plurality of network signals.
S203, switching the network signal to the network signal which accords with the preset rule.
And after the network signal which accords with the preset rule is determined, namely after one network signal with the best network state is determined, switching the network signal to the network signal with the best network state. Specifically, the network signal with the best network state is connected to the wireless router, and the network signal with the best network state is used as a shared network signal and is shared to a plurality of mobile devices.
Because the mobile device is connected with the wireless network signal provided by the portable broadband wireless device by logging in the wireless account, and the network signal switching is only the source for switching the wireless network signal, the user can access the network signal with the best current network state without any operation on the mobile device.
According to the technical scheme, in the switching method disclosed by the application, the portable broadband wireless device can be connected with a plurality of network signals at the same time, the portable broadband wireless device only uses one network signal as a shared network signal at the same time to provide the network signal for the mobile equipment, and the processor controls the switching among the plurality of network signals when the network signal which is currently used as the shared network signal cannot meet the use requirement of the user on the network. Because the portable broadband wireless device does not need to be powered off and the charge card installed in the modem does not need to be replaced, the network can realize switching of network signals without long-time disconnection, and the purpose of providing continuous network signals for users is realized.
The invention discloses another switching method of network signals, which comprises the following steps of:
s301, respectively sending a command for acquiring operator information to each modem;
each modem is connected with the processor through a USB interface extended from the USB HUB, and the wireless router is also connected with the processor.
After a charge card is inserted into each modem, power can be supplied to the modem. When the portable broadband wireless device is started for the first time, namely after being powered on, the mounted modem is enumerated through the USB HUB. Wherein the mounting sequence is the same as the power supply sequence of the plurality of modems. Therefore, the order of mounting can be controlled by controlling the order of power supply to the plurality of modems.
Since the tariff card inserted in each modem may be provided by a different operator, the different operators support different ways of dial-up connecting networks. Therefore, it is necessary to run different dialing programs according to the operator corresponding to the tariff card inserted in each modem, so that each modem can connect to the network signal.
S302, receiving operator information returned by each modem;
the operator information is used to identify the operator of the tariff card inserted by each modem. The operator information may be an international Mobile Subscriber identity, i.e., imsi (international Mobile Subscriber identity). The IMSI identity includes information such as the country and operator to which the SIM card belongs.
The specific form and content of the operator information returned by the modem are not limited in this embodiment. It is sufficient that the operator corresponding to the modem can be determined based on the operator information returned from the modem.
Optionally, in this embodiment, the plurality of modems return at least two different operator information. I.e. different operators of tariff cards inserted by different modems.
Based on this, the portable broadband wireless device provided by the embodiment can connect network signals of multiple operators through multiple modems and keep each network signal connected.
S303, respectively searching a dialing program corresponding to each modem according to the operator information;
the corresponding relationship between the dialing program of each operator and the operator is stored in advance. And after receiving the operator information returned by each modem, analyzing the operator information to determine the operators, and respectively searching the dialing program corresponding to each operator according to each operator through the pre-stored corresponding relation.
S304, sequentially operating the dialing program to enable each modem to be connected with a network signal;
for a modem, after receiving the operator information returned by the modem, analyzing the operator information to determine the operator corresponding to the modem, and finding the dialing program corresponding to the operator. The dial program is run to control the modem to connect the network signal.
In the above manner, each modem is connected to the network signal.
After the dialing program is run, the method may further include:
and sending a request signal of the connection state to each modem and receiving the connection state returned by each modem. And judging whether the modem is connected with a network signal or not according to the received connection state returned by the modem. And when the modem is judged not to be connected with the network signal, operating the dialing program corresponding to the operator of the modem again until the network signal is connected.
In order to enable a user to use a network as soon as possible, the network signal is first used as a shared network signal for a plurality of mobile devices as long as one modem is connected to the network signal.
S305, after receiving a network signal switching command, judging whether a WAN port is connected with a network signal;
if the WAN port is judged to be connected with the network signal, S306 is executed;
if the WAN port is judged not to be connected with the network signal, S307 is executed;
the manner of generating the switching network signal includes manual switching and automatic switching. When the current shared network signal cannot provide the required network bandwidth for the user or the network traffic runs out, the user can manually trigger the network switching signal. After all modems have connected the network signal, the switch network signal may be automatically triggered in order to make the shared network signal the network signal with the best network status.
Because the WAN port directly accesses the network cable, the network provided by the WAN port is stable compared with the network signal on the modem connection. In order to provide a network signal with a good network state to a user, when a WAN port is connected to a network line, that is, a WAN port is connected to a network signal, the network signal provided from the WAN port is preferentially used as a shared network signal. Only when the WAN port has no access to the network cable, that is, the WAN port has no network signal connected thereto, it is necessary to select a network signal with the best network state among the network signals connected to the respective modems as the shared network signal.
It should be noted that the determination of whether the WAN port is connected with the network signal is not limited to the determination of whether the WAN port is connected with the network signal when the portable broadband wireless device is powered on after receiving the network signal switching command.
S306, switching the network signal to the network signal connected with the WAN port;
s307, acquiring parameter information of a network signal connected with at least one modem in the plurality of modems;
s308, determining a network signal which accords with a preset rule according to the parameter information;
s309, switching the network signal to the network signal which accords with the preset rule.
In the handover method provided in this embodiment, the portable broadband wireless device may connect network signals of multiple operators through multiple modems, and when the network coverage of a certain operator is not good at the location of the mobile terminal, the portable broadband wireless device may directly handover to a network signal provided by another operator, thereby implementing the entire network coverage.
Moreover, although the portable broadband wireless device can only provide one network signal as a shared network signal to a plurality of mobile devices at the same time, the network signals of different operators connected to each modem are always connected. When a network signal switching instruction is received, a network signal with the best network state is selected from all currently connected network signals, and the network signal is switched to the network signal with the best network state, so that the rapid network switching is realized, the power is not required to be cut off in the network switching process, the wireless network is not required to be disconnected, and the other wireless network is connected, and the continuity of the network signal is realized.
According to the technical scheme, in the switching method disclosed by the application, the portable broadband wireless device can be connected with a plurality of network signals at the same time, the portable broadband wireless device only uses one network signal as a shared network signal at the same time to provide the network signal for the mobile equipment, and the processor controls the switching among the plurality of network signals when the network signal which is currently used as the shared network signal cannot meet the use requirement of the user on the network. Because the portable broadband wireless device does not need to be powered off and the charge card installed in the modem does not need to be replaced, the network can realize switching of network signals without long-time disconnection, and the purpose of providing continuous network signals for users is realized.
Meanwhile, because a plurality of modems can be connected with network signals of a plurality of operators, the whole network coverage is realized.
