Problems solved by technology

[0005] When the link status is restored, the VoIP terminal will continue to use the IP address to send data to the VoIP server, but since the IP address has been released by the DHCP server, the data sent by the VoIP terminal using the IP address will be considered illegal data , resulting in VoIP service failure

Embodiment Construction

[0050] The embodiment of the present invention provides a data communication method and a communication terminal, which can restore the VoIP service in time when the network returns to normal, thereby improving user experience.

[0051] see figure 1 , an embodiment of the data communication method in the embodiment of the present invention includes:

[0052] 101. The communication terminal uses the obtained IP address to interact with the communication server;

[0053] In this embodiment, when a communication terminal needs to perform communication services, it can first obtain the IP address assigned to the communication terminal from the DHCP server, and use the IP address to register with the communication server, and then use the IP address to communicate with the communication server. The server performs data interaction to perform communication services.

[0054] 102. The communication terminal sends a message to the communication server;

[0055] In this embodiment, ...

Abstract

An embodiment of the invention discloses a data communication method and a communication terminal which can timely recover voice over internet protocol (VoIP) businesses when the network returns to the normal and accordingly improve user experience. The data communication method includes that: the communication terminal transmits messages to a communication server; when the communication terminal does not receive response of the communication server in the preset duration, the communication terminal performs communication channel detection; and if the communication terminal fails in communication channel detection, the communication terminal broadcasts a dynamic host configuration protocol (DHCP) renewal package to renew the internet protocol (IP) address of the communication terminal; if renewal is successful, the communication terminal and the communication server interact. The data communication method and the communication terminal can timely recover the VoIP businesses when the network returns to the normal and accordingly improve user experience.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data communication method and a communication terminal. Background technique [0002] Voice over Internet Protocol (VoIP, Voice over Internet Protocol) is a new voice communication method at present. It can sample, collect and encode the analog voice signal, and compress the voice data encoding through the voice compression algorithm, and then compress the voice data. These voice data are packaged according to the Internet protocol standard, and the data packets are sent to the destination end through the IP network, and the destination end restores these voice data packets to the original voice signal, so as to achieve the purpose of transmitting voice through the Internet. [0003] An existing VoIP terminal can obtain an IP address from a Dynamic Host Configuration Protocol (DHCP, Dynamic Host Configuration Protocol) protocol. Specifically, when a VoIP terminal needs to use ...
