As shown in Figure 1, applicable scene schematic diagram for embodiments of the invention, electronic equipment 103 has wireless routing function, alternatively, electronic equipment 103 is for having the equipment of WiFi wireless routing function, for example this electronic equipment 103 can be smart mobile phone, panel computer, notebook computer or the desktop computer that is provided with WiFi wireless routing module, and this electronic equipment 103 can be by first network 101(for example radio honeycomb number or WLAN (wireless local area network)) Signal share gives and is arranged in for example WiFi network of second network 107() a plurality of access devices 105.Alternatively, access device 105 can be smart mobile phone, panel computer, notebook computer or desktop computer etc.
In an embodiment of the present invention, first network 101 can be GSM(Global System of Mobilecommunication, global system for mobile communications) network, EDGE(Enhanced Data Rate for GSMEvolution, enhanced data rates for gsm evolution) network, EVDO, CDMA2000(Code DivisionMultiple Access2000), WCDMA(Wideband Code Division Multiple Access, Wideband Code Division Multiple Access (WCDMA) access), TD-SCDMA(Time Division-Synchronous Code DivisionMultiple Access, TD SDMA access), TD-LTE(Time Division Long TermEvolution, timesharing Long Term Evolution), FDD-LTE(Frequency Division Duplexing Long TermEvolution, Frequency Division Duplexing (FDD) Long Term Evolution), WLAN(Wireless Local Area Networks, WLAN (wireless local area network)) any one in.
Proposed in an embodiment of the present invention a kind of method of controlling electronic equipment shared network bandwidth, having comprised: the bandwidth that first judges whether to adjust the wireless link that in second network, access device distributes; If judgment result is that the bandwidth that need to adjust the wireless link that in second network, access device distributes, the bandwidth of the wireless link that access device in electronic equipment adjustment second network distributes.Alternatively, electronic equipment adopts geometric ratio bandwidth control strategy and/or priority bandwidth control strategy.
In an embodiment of the present invention, can judge whether to adjust by following three kinds of modes the bandwidth of the wireless link that in second network, access device distributes.
Mode one, judge that whether electronic equipment receives the notification message of adjusting the available bandwidth in first network, if receive this notification message, judgment result is that the bandwidth that need to adjust the wireless link that in second network, access device distributes.
Electronic equipment receiving notice message, this notification message at least comprises with lower at least one: carry the indication that improves or reduce the available bandwidth in first network, adjust the indication of available bandwidth up and/or descending in first network and the amplitude of adjustment or adjust after first network in the information such as available bandwidth desired value.
If this notification message is physical layer message, in this physical layer message, be provided with the indication field that improves or reduce the available bandwidth in first network, adjust the indication field of available bandwidth up and/or descending in first network and the indication field of the available bandwidth desired value in the first network after adjusting range or adjustment, for example in the indication field that improves or reduce the available bandwidth in first network, with a bit, indicate and heighten or reduce bandwidth, " 1 " is for heightening bandwidth, " 0 " is for reducing bandwidth, for example in the indication field of the available bandwidth in adjusting up and/or descending first network, with two bits, indicate and only adjust upstream bandwidth, only adjust downlink bandwidth, adjust uplink and downlink bandwidth simultaneously, " 01 " is for only adjusting downlink bandwidth, " 10 " are for only adjusting upstream bandwidth, " 11 " are for adjust uplink and downlink bandwidth simultaneously, the bit number that the indication field of the bandwidth desired value after adjusting range or adjustment is used can arrange according to actual needs, if it is different to adjust amplitude or the desired value after adjustment of uplink and downlink bandwidth and adjustment simultaneously, this field need to clearly be indicated the amplitude of adjusting upstream bandwidth and the amplitude of adjusting downlink bandwidth, or adjust the desired value of upstream bandwidth and the desired value of adjustment downlink bandwidth.
Take first network as wireless cellular network be example, this notification message can be issued electronic equipment by base station.If electronic equipment accesses wireless cellular network by relaying, this notification message is issued electronic equipment by relaying, relaying can be decided in its sole discretion and adjust the available bandwidth of electronic equipment in wireless cellular network, thereby to electronic equipment, send the notification message of adjusting the available bandwidth of electronic equipment in wireless cellular network, also can adjust according to base station the decision of the available bandwidth of electronic equipment in wireless cellular network, to electronic equipment, send the notification message of adjusting the available bandwidth of electronic equipment in wireless cellular network.
In wireless cellular network, if the bandwidth of all electronic equipments in its coverage is adjusted in base station, the broadcast of adjusting bandwidth can be sent in base station.If base station is only adjusted the available bandwidth of electronic equipment in wireless cellular network or only adjusted the available bandwidth of some equipment in wireless cellular network that comprises electronic equipment, base station needs to electronic equipment, send the notification message of adjusting the available bandwidth of electronic equipment in wireless cellular network separately.
Similarly, when first network is WLAN when net, this notification message can be by AP(access point) issue electronic equipment.
Then, electronic equipment is determined the adjustment result of the available bandwidth of electronic equipment in first network according to the notification message receiving, and adjustment mode is as follows:
(1) if notification message indication only improves the available bandwidth of upstream or downstream N step-length or is increased to bandwidth W, electronic equipment determines that available bandwidth that the adjustment result of its available bandwidth in first network is upstream or downstream is adjusted into available bandwidth and N the step-length sum of former upstream or downstream, or be adjusted into bandwidth W, correspondingly the available bandwidth of downlink or uplink is constant.
(2) if notification message indication only reduces the available bandwidth of upstream or downstream N step-length or is reduced to bandwidth W, electronic equipment determines that available bandwidth that the adjustment result of its available bandwidth in first network is upstream or downstream is adjusted into the poor of the available bandwidth of former upstream or downstream and N step-length, or be adjusted into bandwidth W, correspondingly the available bandwidth of downlink or uplink is constant.
(3) if notification message indication improves (minimizing) N1 step-length or raising (minimizing) to bandwidth W1 by up available bandwidth, and indication improves (minimizing) N2 step-length or raising (minimizing) to bandwidth W2 by descending available bandwidth, electronic equipment determines that the adjustment result of its available bandwidth in first network is that up available bandwidth is adjusted into former up available bandwidth and N1 step-length sum (poor), or be adjusted into bandwidth W1, descending available bandwidth is adjusted into former up available bandwidth and N2 step-length sum (poor), or be adjusted into bandwidth W2.
(4) if notification message indication improves (minimizing) N1 step-length or raising (minimizing) to bandwidth W1 by up available bandwidth, and indication reduces (raising) N2 step-length or minimizing (raising) to bandwidth W2 by descending available bandwidth, electronic equipment determines that the adjustment result of its available bandwidth in first network is that up available bandwidth is adjusted into former up available bandwidth and N1 step-length sum (poor), or be adjusted into bandwidth W1, descending available bandwidth is adjusted into poor (sum) of former up available bandwidth and N2 step-length, or be adjusted into bandwidth W2.
Finally, the adjustment result of electronic equipment available bandwidth in first network according to it, the bandwidth of the wireless link that the access device in employing geometric ratio bandwidth control strategy and/or priority bandwidth control strategy adjustment second network distributes, adjustment mode is as follows:
(1) if adjust the available bandwidth raising that result relates to the upstream or downstream of electronic equipment in first network, electronic equipment improves the upstream or downstream bandwidth of wireless link that accesses all access devices of first network by electronic equipment, or only improves the upstream or downstream bandwidth of the wireless link of the access device that priority is higher.It should be noted that, the priority of access device can be divided according to the type of access device, also can divide according to the type of the current data service of carrying out of access device.
It should be noted that, before the bandwidth of electronic equipment wireless link of access device in improving second network, can judge whether the upstream or downstream bandwidth of the wireless link of the access device distribution that all access devices or priority are higher meets the demand of access device, if satisfied the demands, although the available bandwidth of the upstream or downstream of electronic equipment in first network increases, also can not improve the upstream or downstream bandwidth of the wireless link of any one access device.
(2) if adjust the available bandwidth minimizing that result relates to the upstream or downstream of electronic equipment in first network, electronic equipment reduces the upstream or downstream bandwidth of wireless link that accesses all access devices of first network by electronic equipment, or only reduces the upstream or downstream bandwidth of the wireless link of the access device that priority is lower.
It should be noted that, electronic equipment is before the bandwidth of wireless link that reduces access device, not whether the upstream or downstream total bandwidth of the wireless link distributing for all access devices before can judging the available bandwidth of the upstream or downstream in first network higher than the electronic equipment after reducing, if, although the available bandwidth of the upstream or downstream of electronic equipment in first network reduces to some extent, also can not reduce the bandwidth of the upstream or downstream of the wireless link of access device in any one second network.
In an embodiment of the present invention, while improving the upstream or downstream bandwidth of the wireless link of access device in second network, the upstream or downstream bandwidth of raising wireless link that can equal proportion, also can equal proportion only improve the upstream or downstream bandwidth of wireless link that priority surpasses the access device of default threshold value, can also first improve the upstream or downstream bandwidth of the wireless link of the access device that priority is the highest, when the upstream or downstream bandwidth of the wireless link after improving has met the demand of the access device that priority is the highest or has arrived default threshold value, improve again the upstream or downstream bandwidth of the wireless link of the inferior high access device of priority, by that analogy, according to the priority of access device order from high to low, improve the upstream or downstream bandwidth of the wireless link of access device.
Equally, in an embodiment of the present invention, while reducing the upstream or downstream bandwidth of the wireless link of access device in second network, the upstream or downstream bandwidth of all access devices of minimizing wireless link in second network that can equal proportion, also can equal proportion only reduce priority lower than the upstream or downstream bandwidth of access device wireless link in second network of default threshold value, can also first reduce access device that priority is minimum in the upstream or downstream bandwidth of wireless link, when the upstream or downstream bandwidth of wireless link has reduced to will meet the primary demand of the access device that this priority is minimum or reduce to predetermined threshold value time, reduce again the upstream or downstream bandwidth of the wireless link of the inferior low access device of priority, by that analogy, according to access device priority order from low to high, reduce the upstream or downstream bandwidth of the wireless link of access device.
Alternatively, the up total bandwidth of the wireless link of the access device after adjustment is the up available bandwidth in first network higher than electronic equipment not, and the descending total bandwidth of the wireless link of the access device after adjustment is the descending available bandwidth in first network higher than electronic equipment not.
Mode two, judge that whether the available bandwidth in first network changes, if changed, judgment result is that the bandwidth that need to adjust the wireless link that in second network, access device distributes.
Electronic equipment judges whether its for example, available bandwidth in first network (wireless cellular network or wlan network) changes, as change, adjust all or part accesses the access device of the first network bandwidth of wireless link by electronic equipment, wireless link is the wireless link of for example, setting up between electronic equipment and access device in second network (wlan network).For example periodically judge whether the up available bandwidth of electronic equipment in first network and descending available bandwidth change.
If the up available bandwidth of electronic equipment in access network and/or descending available bandwidth change, adjust the up available bandwidth of wireless link of access device and/or descending available bandwidth.Concrete adjustment process can be referring to the description in mode one.
Mode three, judge that whether electronic equipment carries out data service, if electronic equipment is carrying out data service, judgment result is that the bandwidth that need to adjust the wireless link that in second network, access device distributes.
In an embodiment of the present invention, electronic equipment carries out data service in first network, electronic equipment can initiatively be initiated data service in first network, and now, electronic equipment is initiated data service request to the network side of first network is the triggering of carrying out data service.Electronic equipment also can passively carry out data service in first network, and now, the data service request that the network side of electronic equipment reception first network sends is the triggering of carrying out data service.
Required upstream bandwidth and the downlink bandwidth of data service that electronic equipment prediction is carried out, or required upstream bandwidth and the downlink bandwidth of data service that the network side that receives first network provides, or detect in real time the actual upstream bandwidth taking of data service and the downlink bandwidth carrying out, or periodically detect the actual upstream bandwidth taking of data service and the downlink bandwidth carrying out.
Some data service may only need to take upstream bandwidth, and for example, to network side upload file, the downlink bandwidth that this data service takies may be 0.Some data service may only need to take downlink bandwidth, download file or watch online video for example, and the upstream bandwidth that this data service takies may be 0.
Same, some data service may need to take upstream bandwidth and downlink bandwidth simultaneously, and for example video calling in this case, just need to judge the required or actual upstream bandwidth taking of this data service and downlink bandwidth simultaneously.
Electronic equipment is determined after the data service carry out required upstream bandwidth and downlink bandwidth, the network side that calculates first network is distributed to the poor of the up total bandwidth of electronic equipment in first network and the required or actual upstream bandwidth taking of data service carrying out, obtain the up remaining bandwidth of electronic equipment in first network, and the network side that calculates first network distributes to the poor of the descending total bandwidth of electronic equipment in first network and the required or actual downlink bandwidth taking of data service that carries out, obtain the descending remaining bandwidth of electronic equipment in access network.
Electronic equipment according to it up remaining bandwidth in first network and descending remaining bandwidth adjust the bandwidth of the wireless link of access device in second network.Concrete adjustment process can be referring to the associated description in mode one.
When electronic equipment acquisition stops the triggering message of data service in first network, electronic equipment stops data service, the reason that stops data service can be by a lot, such as initiatively stopping data service, network side, stops data service or because self software and hardware reason is passive, stop data service etc.
It should be noted that, electronic equipment for example, in carrying out the process of the first data service (video calling), also may start to carry out the second data service (for example download file), in this case, can judge upstream bandwidth and the downlink bandwidth that the second business is required by electronic equipment or network side, also can be in real time or periodically detect the first business and the actual up total bandwidth taking of the second business and descending total bandwidth.
As shown in Figure 2, for controlling the method flow diagram of electronic equipment shared network bandwidth in embodiments of the invention, wherein electronic equipment can be transmitted to the access device in second network by the signal in first network, and access device is connected with electronic equipment by wireless link, and concrete steps are as follows:
Step S201, obtain the available bandwidth of electronic equipment in first network.
In this step, electronic equipment starts wireless routing function, and obtain the available bandwidth of electronic equipment in first network, this first network can be the networks such as GSM, EDGE, EVDO, CDMA2000, WCDMA, TD-SCDMA, TD-LTE, FDD-LTE, WLAN, and above-mentioned diverse network is distributed to the available bandwidth of electronic equipment may be different.
In an embodiment of the present invention, the available bandwidth of electronic equipment in first network can refer to that first network is its available bandwidth in first network that electronic equipment distributes, and also can refer to electronic equipment remaining available bandwidth in first network.Particularly, the available bandwidth of electronic equipment in first network can refer to that first network is that electronic equipment distributes, available upstream bandwidth and/or the available downstream bandwidth of electronic equipment in first network, also can refer to that electronic equipment remains available upstream bandwidth and/or residue available downstream bandwidth in first network.
If electronic equipment is by relaying (Relay) access wireless cellular network, the available bandwidth of electronic equipment in first network can refer to the available bandwidth of electronic equipment in the access link between itself and relaying.Equally, the bandwidth of mentioning in the embodiment of the present invention also can be equivalent to flow.
Whether step S203, detected electrons equipment are carrying out data service, if so, and execution step S205.Take this electronic equipment as smart mobile phone be example, this data service can be the data services such as mobile video, mobile TV, Mobile Telephone Gps, mobile phone newspaper.
Whether step S205, the available bandwidth of detected electrons equipment in first network change, if execution step S207; Otherwise, flow process that can method ends.
Namely, electronic equipment detected when carrying out data service, whether can further detect this data service can make the available bandwidth of electronic equipment in first network change, for example the required bandwidth of the data service before the required bandwidth ratio of the current data service of carrying out of electronic equipment is many, the available bandwidth of electronic equipment in first network can be detected in this step with respect to reducing before.Certainly can understand, after execution of step S201, can directly perform step S205.
Step S207, obtain the quantity of the access device in second network.
Namely, obtain the quantity that accesses the access device of first network by electronic equipment.
Step S209, electronic equipment adopt geometric ratio bandwidth control strategy and/or priority bandwidth control strategy, the bandwidth of the wireless link that the access device in adjustment second network distributes.
Above-mentioned wireless link is the wireless link of for example, setting up between electronic equipment and access device in second network (wlan network).
It should be noted that, electronic equipment is in the situation that the available bandwidth in first network is constant, if electronic equipment carries out data service, the bandwidth that may cause electronic equipment can distribute to the wireless link of access device changes, and needs electronic equipment adjustment to distribute to the bandwidth of the wireless link of access device.For example, when electronic equipment carries out video traffic, a part of available bandwidth need to be taken, the bandwidth that electronic equipment can be distributed to the wireless link of access device will be reduced like this.If electronic equipment has stopped data service, at this moment can improve the bandwidth that electronic equipment can be distributed to the wireless link of access device.
It should be noted that, improve electronic equipment and can distribute to the bandwidth of the wireless link of access device, the bandwidth that can refer to the wireless link that improves all access devices, also can adopt priority bandwidth control strategy, only improves the bandwidth of the wireless link of the access device that priority is higher.
Reduce electronic equipment and can distribute to the bandwidth of the wireless link of access device, can refer to the bandwidth of the wireless link that reduces all access devices, also can adopt priority bandwidth control strategy, only reduce the bandwidth of the wireless link of the access device that priority is lower, the compensation of bandwidth adjustment can arrange according to the actual requirements.
Introduce the embodiment that controls electronic equipment shared network bandwidth while adopting geometric ratio bandwidth control strategy in embodiments of the invention below.In this embodiment, electronic equipment obtains the available bandwidth in first network; Then, whether whether detected electrons equipment carry out data service and data service and cause the available bandwidth in first network to reduce; Secondly, electronic equipment obtains the current quantity that accesses the access device of first network by electronic equipment, and the IP address of each access device and the key-value pair of MAC Address; Finally, electronic equipment is according to the available bandwidth in the first network detecting and the quantity of access device, the bandwidth to the corresponding wireless link of corresponding IP address assignment.
As shown in Figure 3, for electronic equipment in embodiments of the invention adopts geometric ratio bandwidth control strategy, control the method flow diagram of shared network bandwidth, the method comprises:
The wireless routing function of step S301, startup electronic equipment, then performs step S303, or execution step S307, for example, start the WiFi wireless routing function of this electronic equipment.
Step S303, obtain the current quantity of the access device of second network, the IP address of each access device and the key-value pair of MAC Address of having accessed.
Alternatively, according to DHCP agreement, obtain IP address and the MAC Address of access device, and IP address and MAC Address can adopt the form of key-value pair to preserve, at this, apply and state no longer in detail.
Whether the IP address of step S305, the quantity that judges access device and/or access device and the key-value pair of MAC Address change, if changed, perform step S311; Otherwise execution step S309;
Step S307, obtain the available bandwidth of electronic equipment in first network, this first network can be the networks such as GSM, EDGE, EVDO, CDMA2000, WCDMA, TD-SCDMA, TD-LTE, FDD-LTE, WLAN, can, by obtaining the network type of first network, obtain the available bandwidth of electronic equipment in first network in an embodiment of the present invention.
Whether step S309, detected electrons equipment carry out data service, and the available bandwidth in the first network that whether causes of data service changes, if the available bandwidth in first network changes, perform step S311; Otherwise execution step S313;
Step S311, when the IP address of access device and when the key-value pair of MAC Address changes or data service initiated by electronic equipment self,, according to the quantity of the available bandwidth in current first network and access device, adopt geometric ratio bandwidth control strategy to adjust the bandwidth of the assigned wireless link of access device.
For example, if the available bandwidth in first network is not more than the total bandwidth of wireless link in second network, adopt the bandwidth of the wireless link that following formula distributes access device to adjust, formula is as follows: Bandwidth
uE=Bandwidth
aP/ NUM, wherein Bandwidth
uEfor the assigned bandwidth of access device, and Bandwidth
aPfor the available bandwidth in current first network, the quantity that NUM is access device; Electronic equipment is that access device is adjusted after the bandwidth of wireless link, can preserve relevant information;
If the available bandwidth in first network is greater than the total bandwidth of wireless link in second network, can adopt following formula to adjust access device and distribute the bandwidth obtaining, formula is as follows: Bandwidth
uEtotal bandwidth/the NUM of wireless link in=second network.
Step S313, replace it the configuration information of front preservation, such as the quantity of the available bandwidth in the first network of current use, access device, the IP address of access device and the key-value pair of MAC Address.Then, circulate according to the time interval arranging, execution step S303 or S307 circulate successively.
It should be noted that, electronic equipment effective bandwidth changes and refers in the constant situation of network type, as at 3G or 4G net environment, because carrying out data service, electronic equipment self caused the situation that in second network, the bandwidth efficient bandwidth of wireless link reduces, or because electronic equipment end self has stopped data service, make the situation of the bandwidth increase of wireless link in second network.
Under the constant prerequisite of the network type of electronic equipment first network of living in, electronic equipment carries out different data service meetings and causes the situation of change of bandwidth also different, for example, video traffic can take larger bandwidth, and the bandwidth that HTTP business takies is relatively little.Therefore, the situation that the bandwidth of wireless link changes in electronic equipment self usage data business causes second network, can take priority bandwidth control strategy, preferentially guarantees that the service on net of priority high user is experienced.
Introducing electronic equipment in embodiments of the invention below adopts priority bandwidth control strategy to control the embodiment of the method for shared network bandwidth.In the method embodiment, electronic equipment obtains the available bandwidth in first network; Then, whether whether detected electrons equipment carry out data service and data service and cause the available bandwidth in first network to reduce; Then, according to the height of optimization level, divide the access device having accessed, and the peak of the bandwidth of the required wireless link of access device is set.Finally, the available bandwidth in first network meets in the situation of bandwidth demand of access device, and the bandwidth of all access devices is not adjusted.If electronic equipment carries out data service, and cause the total bandwidth of the wireless link in second network to change, now, the current available bandwidth in first network of electronic equipment declines larger, if and electronic equipment self carries out after data service, available bandwidth in first network is lower than the maximum of the bandwidth of the required wireless link of the highest access device of priority, and while having continued a period of time, electronic equipment need to be turned down the bandwidth of the access device that other priority is lower or stop providing to these access devices the bandwidth of wireless link, until electronic equipment self uses different pieces of information business or stops using data service, now also can cause the total bandwidth of wireless link in second network to change, the total bandwidth of the wireless link in the second network after variation reaches the bandwidth demand of the wireless link of the access device that priority is the highest, and after continuing for some time, just heighten the bandwidth demand of the wireless link of the access device that other priority are lower.Can guarantee thus, when electronic equipment issues raw situation about switching in high low-bandwidth environment, preferentially guarantee the bandwidth demand of the wireless link of the access device that priority is the highest, meet and then the bandwidth demand of the access device that priority is lower.
As shown in Figure 4, control the method flow diagram of electronic equipment shared network bandwidth when adopting priority bandwidth control strategy in embodiments of the invention, the method comprises:
The wireless routing function of step S401, startup electronic equipment.For example start the WiFi wireless routing function of this electronic equipment.
Step S403, obtain the current quantity of access device and the IP address of each access device and the key-value pair of MAC Address that has accessed second network.
Step S405, for each access device distributes the bandwidth of corresponding wireless link, and the priority of each access device is set.
Alternatively, electronic equipment can be divided according to the type of access device the priority of access device, the priority that also can divide access device according to the presently used type of service of access device, the more bandwidth of access device priority allocation that priority is higher.
Step S407, obtain the available bandwidth of electronic equipment in first network.In inventive embodiment, can obtain the available bandwidth in current network by first network type.
Whether the total bandwidth of the wireless link in step S409, detection second network meets the bandwidth demand of the wireless link of current all access devices, if can meet, performs step S411, otherwise execution step S413.
According to detected electrons equipment self, whether carry out data service, and whether the data service that electronic equipment carries out can cause the total bandwidth of wireless link in second network cannot meet the bandwidth demand of current all access devices.
Step S411, recover the bandwidth of the wireless link of the access device that priority is lower.
Namely, if electronic equipment has stopped the data service of self, or the bandwidth that the data service of using before the bandwidth ratio that the data service of using takies takies reduces to some extent, use current effective bandwidth can meet the bandwidth requirement of all access devices, recovery has stopped the bandwidth of the access device that priority is lower before.
Step S413, stop the bandwidth of the wireless link of the access device that priority is lower.
Namely, if electronic equipment has been initiated data service, or the data service of using than before the bandwidth that takies of the data service used increase to some extent, use current effective bandwidth not satisfy the demands, stop the bandwidth of the access device that priority is lower;
Step S415, preserve the configuration information of all access devices, the IP address of the quantity of access device, access device and the key assignments peer-to-peer information of MAC Address.Then, circulate according to the time interval arranging, execution step S403 circulates successively.
Below in conjunction with geometric ratio bandwidth control strategy and priority bandwidth control strategy, introduce the method flow of the control electronic equipment shared network bandwidth in the embodiment of the present invention.
As shown in Figure 5, for electronic equipment in embodiments of the invention adopts comprehensive bandwidth control strategy, control the method flow diagram of shared network bandwidth, the method comprises:
Step S501, start the wireless routing function of electronic equipment, for example, start the WiFi wireless routing function of this electronic equipment.
