Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] Such as figure 2 As shown, an anti-conflict mobile terminal IP address allocation relay device is deployed between the user terminal and the DHCP server, including:

[0033] A first receiving module for receiving an IP address request message sent by a user terminal;

[0034] A confirmation module for determining the location information of the user terminal and the MAC address information of the device according to the IP address request message;

[0035] A caching module used to record the MAC address and access IP address information of devices connected to the network within a certain period of time. The recording time can be determined according to the update frequency of devices to be assigned IP addresses in practical applications, for example: a certain area within a day One or several mobile devices have been used intermittently. At t...

Abstract

The invention discloses anti-conflict mobile terminal IP address allocation relay equipment and method. The method comprises the following steps: receiving a request message which is sent by a user terminal and used for requesting allocation of an IP address by the relay equipment, determining position information of a client according to the address request message, acquiring a corresponding relationship between the position information and the IP address, determining the IP address corresponding to the position information of the client according to the corresponding relationship, and detecting whether an IP address allocation conflict exists or not according to user online information; and if so, marking a current IP as allocated, reselecting one of remaining unallocated IP addresses randomly, and transmitting the randomly-reselected address to the client. The relay equipment provided by the invention is designed with an address buffer storage, so that an IP address can be reallocated to equipment which is already allocated with an IP address in a short time. Through the technical scheme provided by the invention, the problem of IP address allocation conflict in a DHCP (Dynamic Host Configuration Protocol) server can be solved; the allocation efficiency is increased; and the high efficiency and reliability of an underground communication system are improved.

Description

technical field [0001] The invention relates to an IP address allocation method and equipment in the field of communication technology, in particular to an anti-conflict mobile terminal IP address allocation relay equipment and method. Background technique [0002] The safety of coal mine underground is linked to the safety of people's lives and property. Therefore, it is very important to ensure the safety of the underground as much as possible. For this reason, the smooth and stable underground communication is very important. In order to improve the address allocation speed of underground wireless WiFi and solve the problem of underground address allocation Conflicts, and then improve the quality of underground communication, a variety of solutions have been proposed at present, for address allocation, there is a rapid allocation of IP addresses based on MAC addresses. However, simply according to the correspondence between the IP address and MAC address set by the DHCP s...
