Problems solved by technology

[0014] It can be seen from the above process that in step 104, the MT side needs to wait for the TE to establish a DHCP service and send a DHCP Discover. If the TE side is based on the WINDOWS operating system, the time required to establish a DHCP service is generally about 3 seconds. The entire process Responsible, time-consuming, poor user experience

Embodiment Construction

[0033] The invention proposes a method for shortening the NDIS dial-up connection duration based on the analysis of the dial-up flow and the test data of the experimental network, and the technical scheme of the invention is based on the terminal equipment.

[0034] NS process duration

[0035] 1 Air interface connection establishment process (ms) 3440

[0036] 2 Waiting for TE to establish DHCP service process (ms) 3830

[0037] 3 DHCP negotiation process between MT and TE (ms) 3830

[0038] 4 TE ARP protocol establishment (ms) 1325

[0039] Table 1

[0040] The above Table 1 divides NDIS dial-up into sub-processes, and lists the data obtained from 20 times of dial-up connection tests under the experimental network. As shown in Table 1, the NDIS dialing process is decomposed into sub-processes in sequence, and the column represents the time-consuming corresponding to each sub-process of the NDIS dialing method. Among them, sub-processes 1, 2, and 3 belong to the interact...

Abstract

The disclosure provides a method for quickly establishing a dial-up connection by using a data card, which comprises: when a mobile terminal initiates the dial-up connection from a computer, performing both a process of initiating a wireless connection establishment through a Unified Messaging (Um) port and a process of initiating a Dynamic Host Configuration Protocol (DHCP) server through a Remote Messaging (Rm) port at the same time. Compared with the prior art, in the technical solution of the disclosure, the time for initiating the DHCP server by the terminal equipment (TE) is advanced and is identical to the time for initiating the wireless transmission connection establishment, thus the Um side and the Rm side can initiate the dial-up flow at the same time, and the time for waiting DHCP discover messages and the time for waiting the wireless connection establishment overlap, in this way, the purpose of shortening dial-up time and realizing quick dial-up is achieved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, more specifically, to a data card and a method for rapidly establishing a dial-up connection. Background technique [0002] With the advent of the 3G mobile communication era, compared with network access, wireless data cards have aroused a huge demand for wireless Internet access due to their high speed and mobility, and the dial-up delay of using wireless data cards is also It has become an important user experience indicator. [0003] The data card realizes dial-up Internet access using the TE+MT application mode. TE (Terminal Equipment) is usually a desktop computer (PC) or a notebook computer (Laptop), and MT (Mobile Termination) is a wireless data card or a mobile phone terminal. The interface between TE and MT is called Rm interface, and the interface between MT and wireless network is called Um interface. The dial-up Internet access process of the data card includ...
