Gateway automatic switching method and device, computer storage medium

Cross-reference to related applications

The present application is based on a Chinese patent application filed on Jan. 10, 2016, the entire disclosure of which is hereby incorporated by reference.

Technical field

The present invention relates to the field of wireless communications, and in particular, to a gateway automatic switching method and apparatus, and a computer storage medium.

Background technique

Today, Wireless Fidelity (WIFI) technology provides a simple and fast access method for smart terminals. Whether it is a wireless router, a smart phone or a portable wireless network terminal, it can provide a WIFI access network hotspot for smart terminals. When the device provides the WIFI access network hotspot to the outside world (that is, when working in the hotspot mode), one or more Service Set Identifiers (SSIDs) are broadcasted, and the terminal applies for joining after applying for joining or verifying. After accessing this SSID, the device is connected. If the device has the ability to access the Internet and provide network access services (such as DHCP, NAT, DNS, etc.) for WIFI-accessed terminals, then these terminals can also access the Internet and provide Internet access. The hotspot terminal functions as a gateway at this time. The device acting as a gateway usually accesses the Internet through a mobile network such as 3G/4G.

The user uses the wireless router to provide Internet access to the mobile terminal at home, and the uplink data network does not use the data amount or access time of the Internet as the charging standard; the working unit uses the WIFI hotspot provided by the company to provide Internet access for the mobile terminal. The uplink data network is not above The data volume or access time of the network is used as the charging standard. In addition, when the user goes out, the portable wireless network terminal is used to provide Internet access for other intelligent terminals, and the uplink data network is the mobile network access, and the amount of data on the Internet is used as a meter. Fee standard. Users usually use smart terminals at home or in the company to perform some high-traffic services, such as watching videos, updating applications, etc., thereby saving communication costs. Prior to this, the user had to manually turn off the portable wireless network terminal, thereby allowing other smart terminals to switch to the SSID provided by the access home or company. But users often forget this operation, resulting in more than the expected monthly mobile communication costs.

Under normal circumstances, when users are surfing the Internet, they rarely pay attention to the working status of the access device. For example, when we use the computer to access the Internet, if the service is normal, we will not pay attention to the working status of the upstream router, gateway or switch. The general intelligent terminal does not display the SSID of the access on the main interface, so that the SSID that does not meet the expected access cannot be discovered in time. In addition, after the stable access to an SSID, the smart terminal does not switch to access another SSID. Moreover, when the smart terminal is in the state of WIFI access, the background may perform some large-traffic services, such as system update, user data collection, and the like.

With the popularization and application of personal portable communication devices, communication terminals that people carry with them have the need to access the Internet. Therefore, when people go out, a plurality of portable terminals that are carried around often access the Internet through a gateway function provided by one of the terminals, and the Internet terminal accesses the gateway through WIFI. After users in this networking mode return to a familiar fixed location in their home, it is often necessary to switch each terminal to a gateway device in the home.

Currently, there are several mainstream ways for operators to access the Internet through fixed-line services such as Asymmetric Digital Subscriber Line (ADSL) access, Ethernet access, and passive optical network (PON, Passive). Optical Network) access, mobile network access. The first three access methods usually do not use the data volume or access time of the Internet as the charging standard, and the mobile network access is usually used as the charging standard. As consumers, we prefer to use the former under different access standards. Also, more willing to make Provide more bandwidth resources at home or in the workplace.

detailed description

The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

The embodiment of the present invention is implemented based on the following premise: when the smart terminal works in the station (STA) working mode, after accessing the SSID of multiple gateways, the SSID information of the gateways (also storing its authentication information) is stored, if current The SSID of the gateway is unavailable, and the intelligent terminal automatically accesses the SSID corresponding to other gateways that have already been accessed.

FIG. 1 is a schematic diagram of an application scenario according to an embodiment of the present invention. As shown in FIG. 1 , three devices are involved, namely, a mobile terminal, an intelligent terminal, and a wireless router. The mobile terminal supports the hotspot working mode and can be accessed as a mobile gateway by the smart terminal. A wireless router can also be accessed by a smart terminal as a fixed type of gateway. The SSID corresponding to the mobile terminal as the gateway is SSID2, and the SSID corresponding to the wireless router is SSID1.

As shown in FIG. 1 , the mobile terminal accesses the Internet by using a wireless cellular data communication network, and provides WIFI access for the smart terminal; the wireless router accesses the Internet through the Ethernet data network and provides WIFI access. The access information and authentication information of SSID1 and SSID2 are saved by the intelligent terminal, and the smart terminal keeps the STA working mode on, so that the intelligent terminal can automatically access SSID1 or SSID2 as long as it is within the coverage of SSID1 or SSID2. .

As shown in FIG. 1 , the process indicated by the arrow is that the mobile terminal and the smart terminal are out of the coverage of the SSID 1 and enter the coverage of the SSID 1 at the same time. At this time, it is assumed that the "scanning period" has been configured to be 5 minutes, and the "WIFI hotspot identification list" has been configured to include SSID1. Outside the coverage of SSID1, the mobile terminal cyclically performs SSID scanning in a period of 5 minutes. When the mobile terminal enters the coverage of SSID1, once SSID1 appears in the scanning result, the mobile terminal will turn off the hotspot working mode and perform WIFI enforcement. Sleep or other energy saving measures, such that the smart terminal automatically disconnects from the mobile terminal and attempts to connect with the wireless router.

According to the technical solution of the embodiment of the present invention, when the user is outdoors, the personal terminal device such as the mobile phone and the digital camera carried by the user is connected to the Internet through the MiFi. Specifically, the personal device connects to the MiFi through the WIFI, and the MiFi connects to the Internet through the mobile network such as 4G. After the user returns to a fixed place such as a home, the method of the embodiment of the present invention can automatically switch the user's personal device to a WIFI connection of the fixed place (for example, WIFI of the home gateway), thereby passing the fiber-to-the-home (FTTH) of the home gateway. Fiber To The Home) connects to the Internet. Here, the MiFi corresponds to the mobile terminal acting as the gateway in the embodiment of the present invention, and the personal device corresponds to the intelligent terminal in the embodiment of the present invention, and the home gateway corresponds to the wireless router in the embodiment of the present invention.

In the above solution, after returning from the outdoor to the home, the user can automatically complete the connection of the Internet network without having to manually operate the mobile terminal, thereby improving the user experience and saving the user's MIFI traffic. In addition, after the user switches to the home gateway to access the Internet through the home gateway, the MiFi can enter a sleep state, saving the power consumption of the MiFi.

FIG. 2 is a schematic flowchart of a method for automatically switching a gateway according to an embodiment of the present invention. The automatic gateway switching method in this example is applied to a MiFi device. As shown in FIG. 2, the automatic gateway switching method includes the following steps:

Step 201: Configure a WIFI hotspot identification list.

In the embodiment of the present invention, the method further includes: configuring a scan period.

Specifically, the WIFI hotspot identifier list is configured according to actual conditions and user requirements. The WIFI hotspot identification list will be configured according to the actual situation of the user, and the WIFI hotspot identifier that has been accessed by the smart terminal and is available for a long time. If the MiFi device can work in the STA working mode and access other WIFI hotspots, you can choose to automatically import the WIFI hotspot IDs that have been accessed in the STA working mode to the WIFI hotspot identification list. In addition, the smart terminal also needs to access the WIFI hotspot that the MiFi device accesses in the STA working mode, so as to achieve the purpose of automatically switching the WIFI hotspot.

Step 202: When the hotspot working mode is enabled, access to the Internet through the mobile network, and the terminal is connected to the Internet through the wireless local area network.

Step 203: When the hotspot working mode is enabled and the site working mode is enabled at the same time, the WIFI hotspot within the target range is scanned.

In the embodiment of the present invention, the WIFI hotspot in the target range is periodically scanned according to the scanning period.

Specifically, the MiFi device performs periodic WIFI hotspot scanning according to the scanning period, and stores the WIFI hotspot identifier of the scanning result until the active release.

Step 204: Compare the scan result with the WIFI hotspot identification list.

Specifically, after the MiFi device obtains the scan result, the WIFI hotspot is identified as a comparison item, and compared with the pre-configured WIFI hotspot identifier list, if a certain WIFI hotspot identifier in the scan result and a WIFI hotspot identifier list are selected. If the WIFI hotspot logo is the same, then the WIFI forced sleep or other energy-saving measures will be executed to turn off the hotspot working mode; Continue to perform periodic scans.

For example, the WIFI hotspot identification list pre-configured on the mobile terminal is: {A, B, C}, if the scan result is {E, F, G}, the MiFi device will continue to perform periodic scanning; if the scan result is {C When D, E}, C is the same as the WIFI hotspot identifier in the pre-configured list, so the MiFi device will perform WIFI forced sleep or other energy-saving measures.

Step 205: When the scan result exists in the WIFI hotspot identifier list, the hotspot working mode and the site working mode are turned off, and the sleep state is entered.

In the embodiment of the present invention, the local gateway is controlled to be in a dormant state, wherein when the local gateway is in a dormant state, the hotspot working mode and the site working mode are turned off.

In the above solution of the embodiment of the present invention, the identifier of the WIFI hotspot is an SSID.

Step 301: Configure a WIFI hotspot identification list and a scanning period.

Here, the MiFi device acting as a gateway provides an Ap+Station working mode, and the identifier of the WIFI hotspot commonly used by the user is added to the MiFi device to form a WIFI hotspot identifier list, and the WIFI hotspot identifier list includes one or more WIFI hotspot corresponding identifiers. In addition, the scan period for scanning the WIFI hotspot is configured.

It is worth noting that the WIFI hotspot identification list in this step does not include the identifier corresponding to the WIFI hotspot of the MiFi device, but includes the identifier of other WIFI hotspots.

Step 302: When the hotspot working mode is enabled and the station working mode is turned on at the same time, the scanning of the WIFI hotspot is performed with the scanning period as the cycle.

When the MiFi device works in the AP+Station working mode, the WIFI hotspot scan is performed cyclically with the "scanning period" configured in step 301 as a cycle.

Here, when the hotspot working mode is turned on, the mobile network is connected to the Internet, and the terminal is connected to the Internet through the wireless local area network.

Step 303: Determine whether the scan result exists in the WIFI hotspot identifier list. If yes, go to step 304. Otherwise, go to step 302.

When the WIFI hotspot identifier is the same as the "WIFI hotspot identifier list" configured in step 301, the hotspot working mode and the station working mode are turned off, or other energy saving operations (such as hibernation) are performed. If the smart terminal connected to the mobile terminal accesses the WIFI hotspot corresponding to the scan result and saves, the smart terminal automatically switches and accesses the WIFI hotspot corresponding to the scan result.

Step 304: Turn off the hotspot working mode and the site working mode.

By adopting the solution of the embodiment of the invention, the gateway can be automatically switched, the user's Internet usage is saved, the network hotspot function is enhanced, the function convenience is improved, and the user experience is improved.
