The built-in gateway of the first wireless router is connected with an external network, and the second wireless router is connected with the first wireless router through a network cable. The terminal can access the local area network through wireless network signals of the first wireless router or the second wireless router.

Detailed Description
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings needed to be used in the embodiments of the present invention will be briefly described below, and it is obvious that the drawings described below are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings based on these drawings without creative efforts.
It should be understood that the technical solutions of the embodiments of the present invention can be applied to various communication systems, for example: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), a Long Term Evolution (LTE) System, a LTE Frequency Division Duplex (FDD) System, a LTE Time Division Duplex (TDD), a WiMAX (Universal Mobile telecommunications System, UMTS), or a Worldwide Interoperability for microwave Access (UMTS) communication System, etc.
It should be understood that in the embodiment of the present invention, the Terminal may be referred to as a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (Mobile Terminal), a computer, a microcomputer, or the like. The terminal may communicate with one or more core networks via a Radio Access Network (RAN), for example, the terminal may be a mobile telephone (or "cellular" telephone), a computer with a mobile terminal, etc., for example, the terminal may also be a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device that exchanges voice and/or data with the RAN. The invention is not limited in this respect, for example, the terminal also includes a terminal with a wired access having a multi-bearer feature.
It should be understood that the local area network in the embodiment of the present invention may be a wired local area network or a wireless local area network. Alternatively, the local area network in the embodiment of the present invention may be formed by a wired network and a wireless network.
As described above, in some large-area home or office areas, multiple routers may be used for networking to ensure that network signals cover the entire area. Since gateways are usually integrated in routers in the prior art. Therefore, one of the plurality of routers may be connected to the external network through a built-in gateway. And other routers only use the routing function, and the gateway built in the router is not actually used. While typically, especially when the routers are from the same brand, the IP address of the default gateway set by the multiple routers is typically the same, which may typically be the IP address of the router, e.g., the vendor typically sets the IP address of the default gateway of the router to 192.168.0.1. Therefore, when a plurality of routers in the local area network are networked, a plurality of gateways with the same IP address may exist in the network, and only one gateway capable of actually accessing the internet is provided, and a terminal in the network may be connected to a wrong gateway according to the IP address, thereby resulting in that the internet cannot be accessed normally.
For example, in the networking diagram of fig. 1, the gateway built in the first wireless router in fig. 1 is connected to the external Network through a Wide Area Network (WAN) interface, while a Local Area Network (LAN) interface of the first wireless router is connected to a LAN interface of the second wireless router through a Network cable, and the first wireless router and the second wireless router are networked together, but only the gateway built in the first wireless router is connected to the external Network. If a user needs to send data from a terminal to a gateway, the IP of the gateway needs to be analyzed to obtain a Media Access Control (MAC) address of the gateway, and a process of obtaining the MAC address from the IP address, that is, Address Resolution Protocol (ARP) analysis. If the IP of the default gateway set by the first wireless router and the IP of the default gateway set by the second wireless router are the same, a situation that one IP address corresponds to two MAC addresses occurs in the network, when the ARP resolves the MAC address of the gateway of the first wireless router, if the first wireless router receives data sent by a user, the first wireless router can be connected with an external network through the gateway of the first wireless router, and if the second wireless router receives the data sent by the user, the second wireless router forwards the data to the first wireless router, and then the second wireless router is connected with the external network through the gateway of the first wireless router; when the ARP resolves the MAC address of the gateway of the second wireless router, if the second wireless router receives the data sent by the user, the second wireless router tries to connect to the external network through the gateway of the second wireless router, but the data is not transferred to the first wireless router. The user data will be sent to the wrong place with a 50% probability, so that the internet will not be available with a 50% probability. Moreover, the more routers in the local area network, the greater the probability of the user data transmission error, which affects the user experience.
For example, in the networking diagram of fig. 1, the first wireless router and the second wireless router belong to the same local area network, and the IP addresses of the gateways of the routers in the same local area network are the same (e.g., 192.168.0.1), but the MAC addresses of the gateways corresponding to the routers are different; assume the MAC address of the gateway GW1 of the first wireless router is MAC 1; the MAC address of GW2 of the second wireless router is MAC 2; when the terminal is connected to any router (the terminal may be connected to the first wireless router or the second wireless router), the terminal acquires the IP address (e.g., 192.168.0.1) of the local area network; when the terminal data needs to be sent to the gateway, the IP address (e.g. 192.168.0.1) of the gateway is first resolved by ARP to obtain the MAC address. After receiving the ARP request, the router in the local area network respectively replies messages to the terminals sending the ARP request packets, wherein the reply messages carry the MAC addresses of the routers; the terminal selects the MAC address carried in the message received firstly and connects with the external network through the gateway corresponding to the MAC address. As shown in fig. 1, the MAC addresses of the first wireless router and the second wireless router are MAC1 and MAC2, respectively. If the ARP analysis obtains mac1, the terminal can access the internet if the first wireless router is connected with an external network; if the second wireless router is connected to the external network, the terminal cannot access the network. In the networking diagram of fig. 1, internet access is possible. Similarly, if the ARP resolution results in mac2, the terminal may not access the internet if the first wireless router is connected to the external network, and the user may access the internet if the second wireless router is connected to the external network.
Considering that users are limited by professional knowledge and ability, most users can only perform simple operations of plugging and unplugging network cables and modifying router names and passwords, and some advanced settings cannot be mastered. The situation described above may not be able to find the problem in time and deal with it accordingly. Therefore, the embodiment of the invention provides a communication method, which can be executed by a terminal. The method has the main idea that after the terminal accesses the local area network through the router, when the IP address of the gateway is obtained, if the IP address corresponds to the MAC addresses of the gateways, the gateway capable of being connected with the external network is actively detected, the target gateway capable of being connected with the external network is determined from the gateways, the target gateway is communicated with the external network, the target gateway is automatically determined, the operation of a user is omitted, and the user experience is improved.
The following describes a communication method 100 according to an embodiment of the present invention, where the method 100 may be performed by a terminal, and the method 100 includes:
110, the terminal determines the IP address of the gateway of the accessed local area network;
it should be noted that the terminal may be a terminal accessing the local area network. The terminal can access the local area network through a wireless router or can access the local area network through a wire. The terminal determines the IP address of the gateway, which may be determined by preset default settings, or may obtain the IP address in other manners, which is not limited in the present invention. For example, the terminal may obtain the IP address of the gateway from the router through a Dynamic Host Configuration Protocol (DHCP), or the terminal may manually input the IP address of the gateway through a user.
120, the terminal determines a MAC address corresponding to the IP address, wherein the IP address corresponds to a plurality of MAC addresses, and the plurality of MAC addresses correspond to a plurality of gateways of the local area network one to one;
alternatively, the terminal determines the MAC address corresponding to the IP address, and may send an ARP request packet to each device in the local area network, or the terminal broadcasts the ARP request packet to all hosts on the local area network. After receiving the ARP request packet, each device in the local area network determines whether the IP address in the ARP request packet matches with the local IP address. If not, no response is made. And if the IP address is matched with the MAC address, replying a message to the terminal which sends the ARP request packet, wherein the replying message carries the MAC address matched with the IP address. After the terminal receives the reply message, the MAC address of the gateway matching the IP address may be determined.
Alternatively, the plurality of gateways may be respectively located in a plurality of routers. The plurality of routers may be wireless routers.
130, the terminal determines a target gateway capable of connecting an external network from the plurality of gateways;
alternatively, the external network may be a network other than the local area network. The external network may be, for example, the internet, or it may be another local area network.
Alternatively, a specific method for the terminal to determine a target gateway capable of connecting to the external network from the multiple gateways may be that the terminal, after determining MAC addresses of the multiple gateways corresponding to the IP address, sequentially binds the IP address to the MAC addresses of the multiple gateways, and after binding the MAC address of the gateway each time, the terminal tests whether the external network can be connected through the bound gateway, and if the external network can be connected, the terminal determines the gateway as the target gateway and may perform static ARP binding on the IP address and the MAC address of the target gateway. If the external network can not be connected, the terminal binds the IP address with the MAC address of the next gateway again until a target gateway is determined or all gateways are tested.
Alternatively, the terminal tests whether the external network can be connected through the bound gateway, and the terminal tests whether the internet can be connected through the bound gateway. It is possible to test whether a known website such as hundredths, Google (Google), etc. can be connected.
140, the terminal communicates with the external network through the target gateway.
In the embodiment of the invention, after the terminal determines the plurality of MAC addresses corresponding to the IP addresses of the gateways of the accessed local area network, the terminal determines the target equipment capable of being connected with the external network from the plurality of equipment corresponding to the plurality of MAC addresses and determines the target equipment as the target gateway, so that the terminal does not need to be set by a user, can automatically determine the target gateway and improves the user experience.
The following describes a flow of a specific embodiment of the communication method according to an embodiment of the present invention in detail. As described below, the process includes, assuming that the terminal is located in a local area network networked by a plurality of wireless routers:
(1) the terminal accesses the local area network through any router and acquires the IP address of the gateway of the local area network;
(2) the terminal performs ARP detection (for example, a broadcast ARP detection packet) according to the IP address;
(3) if the terminal receives a plurality of MAC addresses responding to the ARP detection packet, the terminal indicates that a plurality of gateways in the local area network correspond to the IP addresses, and the gateways can be named as GW1 and GW2 …
(4) The terminal performs static ARP binding on the IP address and the MAC address of GW1, accesses an external network (for example, accesses a famous website such as Baidu or Google) and determines whether the external network can be connected through GW 1;
(5) if GW1 can connect with external network, then GW1 is determined as target gateway, and the process ends; if GW1 is not capable of connecting to the external network, proceed to the next step;
(6) the terminal performs static ARP binding on the IP address and the MAC address of the next gateway and determines whether the external network can be accessed or not until a target gateway which can access the external network is determined; or testing all gateways, if all gateways can not surf the internet, not binding any gateway, and ending the process.
Optionally, after the terminal determines the target gateway, the terminal may preferentially connect to the external network through the determined target gateway. If the terminal determines that the external network cannot be connected through the determined target gateway when the target gateway is changed due to a change in a networking mode or other reasons, the terminal may perform step 120 and step 130 again to re-determine the MAC address of the target gateway, and then connect the external network through the re-determined target gateway.
In the embodiment of the invention, under the condition that the IP address of the gateway corresponds to the MAC addresses of a plurality of gateways, the terminal can ensure that the user can normally connect the external network under the condition of a plurality of gateways by automatically detecting and binding the target gateway capable of connecting the external network, thereby improving the user experience.
