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 invention provides a method for a data card to rapidly establish the dialing connection, which comprises the following steps that: when dialing connection is started on a computer on a mobile terminal, the Um interface starting wireless connection establishing process and the Rm interface starting DHCP server process are simultaneously performed. Compared with the prior art, the time for starting DHCP server by TE is advanced by the technical scheme of the invention to be the same with the time for starting the wireless transmission connection establishment, so the starting of the dialing flow can be simultaneously performed at the Um side and the Rm side, the time for waiting for the DHCP discover information is overlapped with the time for waiting for the establishment of the wireless connection, and the dialing time is shortened and the rapid dialing can be realized.

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...
