Problems solved by technology

[0003] In the traditional IP dynamic acquisition method based on the Dhcpcd service, according to the lease file, when renewing the IP, there is no guarantee that the lease file is authorized by the currently connected hotspot, which may cause the IP renewal to fail, and the DHCP discovery process is re-initiated, that is, The DHCP client resends the DHCPdiscover discovery message to request a new IP address. This process prolongs the time to obtain the IP and reduces the user experience.

Embodiment Construction

[0018] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0019] MAC (Medium / MediaAccessControl) address, or MAC address, physical address, is used to represent the identifier of each site on the Internet, expressed in hexadecimal, with a total of six bytes (48 bits). Among them, the first three bytes are the codes (high 24 bits) assigned to different manufacturers by IEEE’s registration authority RA, also known as "Organizationally Unique Identifier", and the last three bytes (low 24 bits) is assigned by each manufacturer to the adapter interface produced by itself, which is called an extended identifier (uniqueness). An address block can generate 2 24 different addresses. The MAC address is actually the adapter address or adapter identifier EUI-48.

[0020] see figure 1 , is a structural bl...

Abstract

The invention discloses an IP setting method based on a lease file, including: S1, judging whether the lease file corresponding to the MAC address of the hotspot is successfully opened; S2, sending DHCP when successfully opened? request request information to the corresponding DHCP server to obtain the leased IP; S3, DHCP server received DHCP? After the request requests information, determine whether the previous IP address is available, if so, make the DHCP client use the previous IP address and reply to DHCP? ACK confirms the information to the DHCP client; S4, judging whether the DHCP client has received the DHCP? ACK confirmation information; S5, when it is determined that the DHCP client receives the DHCP? When the ACK confirms the information, update the lease file corresponding to the MAC address of the hotspot. The invention also discloses an IP setting system based on lease documents.

Description

technical field [0001] The invention relates to the communication field, in particular to an IP setting method and system based on a lease file. Background technique [0002] Before the DHCP client performs data communication on the terminal of WiFi wireless communication, for example, before the data transaction of WiFi-POS, it first needs to connect to the network through WiFi. The current mainstream is to realize the dynamic acquisition of IP based on the Dhcpcd service. [0003] In the traditional IP dynamic acquisition method based on the Dhcpcd service, according to the lease file, when renewing the IP, there is no guarantee that the lease file is authorized by the currently connected hotspot, which may cause the IP renewal to fail, and the DHCP discovery process is re-initiated, that is, The DHCP client resends the DHCPdiscover discovery message to request a new IP address. This process prolongs the time for obtaining an IP and degrades user experience. Contents of ...
