Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
In order to better understand the scheme of the embodiments of the present application, the following first introduces the related terms and concepts that may be involved in the embodiments of the present application.
A Subscriber Identity Module (SIM), also called a SIM card, is used to implement a connection to a Mobile network, such as a Global System for Mobile Communications (GSM) network or a Universal Mobile Telecommunications System (UMTS) network. The Subscriber Identity Module used in the LTE 3GPP standard is also referred to as Universal Subscriber Identity Module (USIM), which is also a type of SIM. The SIM card is a Universal Integrated Circuit Card (UICC).
The IP Address is a unified Address format provided by the IP Protocol, and allocates a logical Address to each network and each host on the Internet, so as to shield the difference of physical addresses. On the Internet, each node is distinguished from and associated with each other by means of a unique IP address. IP addresses include two types: IPV4 and IPV 6. The IPV4 is a 32-bit binary address consisting of 4 8-bit fields, each separated by a dot number, for identifying the TCP/IP host. Each IP address contains two parts, a network ID and a host ID. Compared to IPV4, IPV6 increases the address length from 32 bits to 128 bits, which can support more address requirements. The network ID identifies all hosts on the same physical network, and the host ID identifies each host on the physical network, so that each computer on the whole Internet is identified by means of a unique IP address.
The Domain Name System (DNS) is a distributed database on the internet as a mapping between Domain names and IP addresses, enabling users to access the internet more conveniently without having to remember IP strings that can be read directly by a machine. The process of mapping a domain name to an IP address is known as "domain name resolution". The domain name resolution needs to be completed by a special domain name resolution server, and the DNS is a server for domain name resolution. When a user enters a DNS name (domain name) in an application, the DNS server can resolve the name to an IP address corresponding thereto. Therefore, the domain name input by the user during surfing the internet can be finally surfed only through the IP address pointed by the domain name.
A terminal device, also called a User Equipment (UE), is a device providing voice and/or data connectivity to a User, such as a handheld device with a wireless connection function, a vehicle-mounted device, and so on. Common terminal devices include, for example: a Mobile phone, a tablet computer, a notebook computer, a palm computer, a Mobile Internet Device (MID), a wearable Device, an intelligent bracelet, a pedometer, a motion Picture Experts Group Audio Layer 3 (MP 3 player), a motion Picture Experts Group Audio Layer 4 (MP 4) player, a Personal Digital Assistant (PDA), a laptop computer, and the like.
A network device, which may also be referred to as a routing device, is a device deployed in a radio access network to provide a wireless routing function, for example, any routing device or access device between a terminal device and a PDN, such as an MIFI router.
At present, the MIFI can support a plurality of SIM cards, a terminal device can activate a PDN as a data card through the SIM card 1, and connect the MIFI through a WIFI hotspot or a USB to access the internet, but when the SIM card 1 cannot access the internet due to some reasons (for example, data traffic is used up), the data card needs to be switched to the SIM card 2, and when the data card is switched, PDN activation needs to be performed on the SIM card 2, and WIFI hotspot and USB network sharing are restarted. However, after the SIM card 2 completes PDN activation, the information of the external network card (such as IP address, DNS Server, etc.) changes, and the terminal device needs to reconnect the MIFI and acquire correct external network information. Therefore, in the process of switching the SIM card, the terminal device connected to the MIFI may not be available for a long time, which affects the user experience.
In order to solve the above problem, the present application provides a data card switching method, where a terminal device is switched from a first SIM card to a second SIM card, and a network type supported by the second SIM card is IPV6, a route notification message sent by a network device is received to obtain an IPV6 prefix of the second SIM card and a domain name system DNS proxy lease, so that the terminal device can quickly connect to a network, recover an internet access function, and improve user experience.
In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a data card switching method according to an embodiment of the present disclosure. As shown in fig. 1, the method includes the following steps.
S110, when the data card is switched from the first SIM card to the second SIM card, the network equipment acquires the network type supported by the second SIM card.
The network device may be an MIFI router connected to a terminal device. When the MIFI router uses the first SIM card as a data card to perform data communication with the PDN, but the first SIM card cannot be used as the data card for any reason to go on the internet (for example, data traffic runs out, etc.), the MIFI router may switch the data card from the first SIM card to the second SIM card. In the switching process of the data card, the second SIM card needs to be activated by the PDN and then reconnected with the MIFI to acquire the IP address and the DNS proxy service for the correct internet access, so that the time consumption is long, and the terminal equipment cannot access the internet for a long time. Therefore, in the embodiment of the application, when the network device switches the data card from the first SIM card to the second SIM card, the MIFI may obtain the network type supported by the second SIM card, and further determine the measure for obtaining the internet access parameter of the terminal device according to the network type supported by the MIFI, so as to reduce the time for recovering the internet access when the network device performs the SIM card, and improve the user experience.
Optionally, the method further includes: before the network types supported by the second SIM card are obtained, the connection with the first SIM card is disconnected, and the connection with the second SIM card is established.
When the network device uses the first SIM card as a data card for data communication, the first SIM card needs to perform PDN activation, that is, a connection between the first SIM card and the PDN is established, and the internet access parameters (such as subnet mask, IP address, DNS proxy lease, gateway, operator, and the like) corresponding to the first SIM card are acquired, so that the first SIM card uses the corresponding internet access parameters to perform data communication with the PDN.
Specifically, when the MIFI router switches the data card from the first SIM card to the second SIM card, the external network gateway may change, and the internet access parameter corresponding to the first SIM card may not be applicable to the second SIM card. Therefore, when the data card is switched from the first SIM card to the second SIM card, the MIFI router can perform PDN deactivation operation on the first SIM card so as to disconnect the connection with the first SIM card and cancel the internet access parameter corresponding to the first SIM card stored in the terminal equipment. And meanwhile, the MIFI router performs PDN activation operation on the second SIM card to establish connection with the second SIM card, so that the internet surfing parameters corresponding to the second SIN card are sent to the terminal equipment for updating.
Further, the method further comprises: and updating NAT translation configuration parameters and routing parameters. When the data card is switched from the first SIM card to the second SIM card, because the network card of the external network changes, the NAT conversion configuration parameters and the routing parameters of the network device during data communication also change. Therefore, when the data card is switched, the MIFI router can update the NAT conversion configuration parameters and the routing parameters used after the data card is switched, so that the terminal equipment can recover to surf the internet.
S120, when the network type is IPV6, the network equipment sends a first routing notification message to the terminal equipment, wherein the first routing notification message carries the IPV6 prefix of the second SIM card and a Domain Name System (DNS) proxy lease.
When the type of the network supported by the second SIM card is IPV6, the IPV6 uses a Global address, the external network card changes, the allocated address also changes, and the IPV6 needs to update using the Global address and DNS service. However, since the terminal device cannot know the process of switching the data card from the first SIM card to the second SIM card by the MIFI Router, when determining that the network type supported by the second SIM card is IPV6, the MIFI Router sends a first Routing Advertisement (RA) message to the terminal device, where the first routing Advertisement message may carry an IPV6 prefix and a proxy lease of an external network card corresponding to the second SIM card, and the lifetime of the first routing Advertisement message is set to a valid value. Therefore, the terminal device receives the first route advertisement message and then updates the IPV6 prefix and domain name system DNS proxy lease of the second SIM card on the terminal device.
Optionally, before sending the first route advertisement message to the terminal device, the method further includes: and sending a second route advertisement message to the terminal equipment, wherein the second route advertisement message is used for indicating that the IPV6 prefix and the DNS proxy lease corresponding to the first SIM card are invalid.
In this embodiment of the application, after the MIFI router switches the data card from the first SIM card to the second SIM card, a second route advertisement message may be sent to the terminal device first, where the second route advertisement message may carry the IPV6 prefix and the proxy lease of the extranet card corresponding to the first SIM card, and set the lifetime of the second route advertisement message to 0.
Correspondingly, the terminal device receives the second route advertisement message from the network device, and since the lifetime of the second route advertisement message is 0, the terminal device, after receiving the second route advertisement message, will deregister the IPV6 prefix and the proxy lease carried in the second route advertisement message, that is, deregister the IPV6 prefix and the DNS proxy lease corresponding to the first SIM card.
S130, the terminal equipment receives the first route advertisement message from the network equipment, and carries out data communication to a public data network PDN based on the IPV6 prefix and the DNS proxy lease.
Specifically, after receiving the first route advertisement message sent by the MIFI router, the terminal device may use the IPV6 prefix of the second SIM card and the DNS proxy lease carried by the terminal device as the IPV6 prefix of the terminal device for surfing the internet and the DNS proxy lease. When the terminal device needs to communicate data with the PDN, the terminal device may send a packet to the MIFI router using the updated IPV6 prefix and the DNS proxy lease. After receiving the data packet, the MIFI router normally processes NAT conversion and route forwarding to realize data communication with the PDN, so that the terminal equipment can quickly recover to surf the internet.
It can be seen that, when the network device switches the data card from the first SIM card to the second SIM card and the network type supported by the second SIM card is IPV6, the method receives a first routing advertisement message from the network device, where the routing advertisement message carries an IPV6 prefix of the second SIM card and a domain name system DNS proxy lease, so that when the data card is switched from the first SIM card to the second SIM card, the terminal device can quickly connect to the network device, recover the internet access function, and improve user experience.
Referring to fig. 2, fig. 2 is a schematic flow chart of another data card switching method according to an embodiment of the present disclosure. As shown in fig. 2, the method includes the following steps.
S210, when the data card is switched from the first SIM card to the second SIM card, the network equipment acquires the network type supported by the second SIM card.
S220, when the network type is IPV6, the network equipment sends a first routing notification message to the terminal equipment, wherein the first routing notification message carries the IPV6 prefix of the second SIM card and a Domain Name System (DNS) proxy lease.
And S230, when the network type is IPV4, the terminal equipment receives a first route notification message from the network equipment, and performs data communication to a Public Data Network (PDN) based on the IPV6 prefix and the DNS proxy lease.
The specific implementation manners of S210-S230 may refer to the specific implementation manner described in fig. 1, and are not described herein again.
S240, when the network type is IPV4, the terminal device keeps first information unchanged and performs data communication to the PDN based on the first information, wherein the first information comprises at least one parameter required by the terminal device to connect the network device.
Because the IP address of the IPV4 is the IP address of the lan, when the terminal device does not move or does not move outside the lan, the IP address used by the terminal device to access the internet does not change. Therefore, in this embodiment of the application, when the network type supported by the second SIM card is IPV4, the parameter of the terminal device accessing the internet is not changed. The terminal equipment can use the previous internet surfing parameters to send a data packet, and the MIFI router receiving the data packet normally processes NAT conversion and routing forwarding to realize data communication with the PDN, so that the terminal equipment can quickly recover internet surfing.
In the embodiment of the application, when the network device switches the data card from the first SIM card to the second SIM card, if the network type supported by the second SIM card is IPV4, the parameter of the terminal device that accessed the internet before is directly used for data communication with the PDN, so as to reduce the time for the terminal device to quickly recover from accessing the internet; if the network type supported by the second SIM card is IPV6, the first routing advertisement message sent by the network device is received to obtain an updated IPV6 prefix and DNS proxy lease, so that the terminal device can connect to the network device quickly, recover the internet access function, and improve user experience.
