Detailed Description
To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
For convenience of describing the embodiments of the present invention, the Bandwidth (english: Bandwidth) in this document refers to the frequency Bandwidth occupied by the signal; when used to describe a channel, bandwidth refers to the maximum frequency bandwidth of a signal that can effectively pass through the channel. Bandwidth in digital devices is expressed in bps (b/s). In the field of telecommunications, data transmission rate or transmission rate in short refers to the average value of bits, characters, or blocks transmitted between data transmission system devices in a unit of time.
For convenience of illustration, in the specific embodiment, the first network and the second network are GPRS, 3G, 4G, 5G, wifi, dial-up connection, and the first network bandwidth and the second network bandwidth are bandwidths of the networks. The first and second network bandwidths are limited by the bandwidth allocated to the external network, which is a fixed value in some cases, for example, 10M bandwidth is allocated to the master device, but in some cases, the bandwidth allocated to the master device is changed, for example, the signal is weak at the corner 4g of the public area, and then the bandwidth value that can be used by the master device is small.
The current bandwidth (sometimes also described as the current bandwidth usage) that distinguishes the first network bandwidth from the second network bandwidth is the current actual amount of packet switching per second by the master device, which is limited to the first network bandwidth and the second network bandwidth.
Referring to fig. 1, a connection method of a bluetooth dial-up network according to the present embodiment is shown, in which a computer 101 is connected to a local area network or a wide area network, and the computer has a bluetooth module capable of opening a bluetooth network sharing function. The mobile phone also has a Bluetooth module, which can be connected to other Bluetooth modules to share their network connection. At this time, we also refer to the computer end as gateway equipment and the mobile phone end as a data terminal.
Referring to fig. 2, fig. 2 shows a network protocol model of a gateway device and a data terminal in establishing and using a bluetooth dial-up network. The baseband and link control layers of the baseband protocol ensure the physical connection formed by radio frequency between each bluetooth device unit in the piconet. The connection management protocol (LMP) is responsible for the establishment of connections between bluetooth devices. A logical link control and adaptation protocol (L2CAP), which operates in parallel with the LMP, is different in that the L2CAP provides services to an upper layer when traffic data does not pass through the LMP. Service Discovery Protocol (SDP), which plays a crucial role in the bluetooth framework, is the basis for all user modes. The cable replacement protocol (RFCOMM) is a serial line emulation protocol based on the ETSI-07.10 specification. It emulates RS-232 control and data signals over the bluetooth baseband protocol to serve upper layer protocols (e.g., OBEX) that use a serial line transfer mechanism. Application layer (application) the application layer accesses some lower layer procedures (e.g., establishment of SCO synchronous links).
The inventor finds that a network data counting module is added on or above an application layer and is used for counting network data flow used by the application layer in a Bluetooth dialing network protocol of a master device, and then calculating network data transmission flow of a slave device.
In some embodiments, a method of bandwidth control in a bluetooth shared network process, as shown in figure 3, comprises the steps of,
s301, the master device is connected to a network through a first network;
s302, the master device shares a first network to the slave device;
s303, detecting the network data transmission rate of the main equipment;
s304, when the network data transmission rate of the main equipment exceeds a set value, executing a first preset operation;
the set value is a value greater than or equal to the current first network bandwidth 1/2.
In the above embodiments, the first network is a wireless network or a wired network, the wireless network is a wireless local area network formed by using radio waves as a medium for information transmission, and the purpose of the wireless local area network is very similar to that of the wired network, and the greatest difference lies in that the wireless local area network uses a radio technology instead of a network cable. Such as a wireless fidelity Wi-Fi network, a wireless fidelity direct Wi-Fi direct network, 5g, 4g, 3g, 2g, etc., and may also be other wireless protocols or wireless networks with the development of technologies. The master device may range to a local area network or a wide area network by connecting to the first network.
The slave device is connected to the master device via bluetooth, and forms a Personal Area Network (PAN) with the master device via a bluetooth dial-up network protocol (dun), which uses frequency hopping spread spectrum to transmit data over short distances from fixed or mobile devices. The slave device is connected with the access network through the Bluetooth, and compared with other common wireless networks such as wifi and 4g, the power consumption is low, and the standby time of the device can be prolonged. In other usage scenarios, for example, when the slave device cannot be connected to the network through the operator (for example, the phone card in the home country cannot be used after going out of the country) or because the network traffic rate of the master device is lower, the bluetooth sharing network is turned on by the master device, the slave device is connected to the master device through bluetooth, and shares the network of the master device, and the standby time of the master device can be better prolonged by using the bluetooth sharing network than by turning on the wifi hotspot sharing network by the master device.
The network data transmission rate of the master device is then obtained through network monitoring, and in different embodiments, the monitoring of the data transmission rate may be different, for example, the average data transmission rate of the master device at this minute, that is, the data transmission rate of the master device, may be obtained by measuring the total flow rate of the master device within 1 minute and then dividing the flow rate value by 60 seconds. The average value of the network data transmission rate in a longer time period may also be used, and for example, the average value of the network data transmission rate of the master device in 2 minutes may be used as the network data transmission rate for the next determination.
When the measured network data transmission rate exceeds a set value, which is a bandwidth value equal to or greater than the current network bandwidth 1/2, a first preset operation is performed. The setting value may be different values according to different embodiments, and may be a bandwidth value of 2/3, a bandwidth value of 3/4, or the like. The setting may be a network data transfer rate that facilitates differentiation of a user's network access behavior, for example, a rate value that differentiates whether the user is browsing a web page or watching a video. Since the common bitrate of most network videos is 720p at present, the preferred setting value can be set to be a multiple of the bandwidth required for playing 720p videos, and the multiple is not necessarily an integer. For example, when the user often plays 480p network video, since the bandwidth required for playing 480p is about 0.4 times the bandwidth required for playing 720p video, the setting value can be set to 0.4 times the bandwidth required for playing 720p video. When the network data transmission rate of the main device is detected to be equal to or multiple of the bandwidth required by playing the 720p video, the network of the main device is switched to be connected to a 4G network or a network with the bandwidth larger than 4G, such as a wifi network, so as to ensure the fluency of the played network video.
The first preset operation comprises the operation of switching the network of the main equipment or providing convenience and prompt for the switching operation.
In some embodiments, the performing the first preset operation includes prompting a current network bandwidth usage amount, and displaying a connectable second network according to a currently available network, the second network having a bandwidth greater than the first network bandwidth. The user is prompted about the current network usage amount, so that the user can understand why the current network access is not smooth, and the network usage experience of the user is improved. In other embodiments, the connectable second network is displayed or prompted for the user, so that the user can conveniently switch the network to be connected to a network which is faster than the first network, and convenient switching operation is provided for the user.
In some embodiments, the performing the first preset operation includes the master device switching the first network to be connected to the second network; the bandwidth of the second network is greater than the bandwidth of the first network. This will directly simplify the handover network operation steps made by the user. Switching from the first network to the second network is switching from the low speed network to the high speed network, for example, switching from 2g to 3g, switching from 3g to 4g, switching from 4g to 5g, or switching from 2g to 4 g. The master switching network typically disconnects the first network and connects to the second network. In other cases, the network bandwidth of wifi corresponding to the current can be known according to the wifi broadcast frame, the wifi is sequenced according to the wifi network bandwidth, and when the first network is connected to the wifi network, the connection to the second network can be the wifi with the largest current bandwidth or the wifi with the best current signal.
In some embodiments, the first network is connected to the second network after the first network is disconnected, and then the first network is connected to the second network.
By detecting the network data transmission rate of the main equipment, whether the website accessed by the user belongs to a video website or a text and picture type website is predicted through the network data transmission rate, and then a proper network connection is prompted or allocated to the user. The network access experience of the user is improved, and meanwhile, when the high-speed bandwidth is not needed, the low-network-speed bandwidth network with low power consumption is selected to be connected, so that the use and standby time of the mobile equipment can be prolonged.
In other embodiments, when the master device network data transmission rate exceeds the maximum bandwidth of the currently available network, the first network and the second network are simultaneously turned on to increase the network access bandwidth of the master device. In some embodiments, the master device and the slave device form a Personal Area Network (PAN) through a bluetooth dial-up network, and then in the bluetooth sharing process, it may be determined which network the master device and the slave device are respectively dedicated to use according to their respective network data transmission rates for a period of time, for example, the master device has video access, the slave device mainly has text-type web access, the master device is dedicated to the second network, and the slave device accesses the first network through the bluetooth dial-up network of the master device. In other embodiments, the master device and the slave device may mix the first network and the second network, and the master device obtains the maximum network bandwidth by simultaneously starting and using the first network and the second network.
In other embodiments, the master device presets the traffic value of the shared network that the slave device can use, and when the traffic value of the shared network that the slave device uses reaches a preset value, or the master device presets the time that the slave device can use the shared network, and when the slave device use time exceeds the preset value, the second preset operation is performed. The sharing network is a network shared by the master device to the slave device through Bluetooth. The flow value of the slave equipment is counted, so that a user, particularly a user ordering the flow package, can know the flow use condition in the Bluetooth network sharing in time, and the user can take preset measures in time for the network data flow which is about to be over-rated or is over-rated. In some cases the second predetermined operation may be to disconnect the network that the master device shares to the slave device via bluetooth. Or to inform the master or slave device that the network shared to the slave device over bluetooth will be disconnected.
In other embodiments, in bluetooth network sharing, the master device also sets a port through which the slave device can access the bluetooth, i.e., the master device also sets a port for bluetooth dial-up network connection. The open port is generally a default port, or may be an open port set by a user through a setting interface. And when the Bluetooth connection is authenticated, the port information of the two parties in the negotiation information of the Bluetooth connection. And judging whether the port requested to be connected by the slave device is included in the port set to be opened by the master device, if so, allowing the connection, and otherwise, not connecting. This step can be implemented in the bluetooth protocol, and also can be implemented by the relevant interface in the bluetooth protocol stack. By setting the development port, illegal access requests or Bluetooth connection requests can be rejected.
In other embodiments, in bluetooth network sharing, the master device further sets an accessible network address of the slave device for restricting network access of the slave device and protecting secure access of the slave device network. When the network access request is sent from the slave device to the master device, and the network access request accesses an address other than the network address which can be accessed by the master device set by the slave device, the master device discards the network access request.
In other embodiments, the method further comprises the step that the master device returns the inaccessible prompting information to the slave device. In some cases, the user may be prompted that the master device in bluetooth sharing has set access address filtering, and in other cases may be placed back 404 directly or otherwise have no access to the prompt.

S401, the main equipment is connected to a network through a first network;
s402, the master device shares a first network to the slave device;

Namely, when the network data transmission rate of the main equipment is at the low level of the current network bandwidth, the third preset operation is executed. The lower bits of the network bandwidth may be defined as a bandwidth value smaller than or equal to current network bandwidth 1/2, or may also be defined as a bandwidth value smaller than or equal to current network bandwidth 1/3, or may be defined as a bandwidth value of network bandwidth 1/4. The third preset operation comprises the operation that the main equipment network is switched to low bandwidth or convenience and prompt are provided for the switching operation.
In still other embodiments, the performing the third preset operation includes prompting a current network bandwidth usage amount, and displaying a connectable second network according to a currently available network, wherein a bandwidth of the second network is smaller than a bandwidth of the first network.
In some embodiments, the performing the third preset operation includes switching, by the master device, the first network to be connected to the second network; the bandwidth of the second network is less than the bandwidth of the first network.
By actively detecting the network data transmission rate of the main equipment, whether the website accessed by the user belongs to a video website or a text and picture type website is predicted through the network data transmission rate. When the main device does not need high bandwidth connection, the main device selects a low network speed bandwidth network with low power consumption, which is beneficial to prolonging the use and standby time of the mobile device.

The network data transmission rate of the main equipment is detected, and the type of the network operation of the user is predicted according to the network data transmission rate, so that the user is prompted or allocated with proper network connection. The network access experience of the user is improved, and meanwhile, when the high-speed bandwidth is not needed, the low-network-speed bandwidth network with low power consumption is selected to be connected, so that the use and standby time of the mobile equipment can be prolonged.
