Wireless moile double-mode network card, method for its working mode control and power supply management

Abstract

The method includes following steps: when user starts up, the signal from WLAN is firstly checked; if the signal from WLAN is strong enough, then it will access to WLAN network; if the signal from WLAN is not checked, then it will access the network through GPRS; when user access network through GPRS, the bimodule network card will periodically start up WLAN at an interval of several minutes and scan signal of WLAN; according to scanning result the bimodule network care will decide access path.

Description

technical field [0001] The invention relates to a network card for wireless mobile communication, in particular to a working mode control and power management method of a WLAN / GPRS dual-mode network card. Background technique [0002] WLAN / GPRS dual-mode network card refers to a network card that integrates the dual functions of a wireless local area network WLAN (Wireless LAN) network card and a general wireless packet service GPRS (General Packet Radio Service) network card. Generally speaking, a dual-mode network card is composed of the following modules : SIM card reader function module (SIM, Subscriber Identity Model, Subscriber Identity Module), control module, WLAN function module, GPRS function module and dual-mode network card client module. There are two ways for users to access the Internet through the dual-mode network card, namely: using the WLAN part of the dual-mode network card to access the network through the WLAN access point device AP (Access Point). Or ...

AI Technical Summary

Problems solved by technology

[0007] 1. The general dual-mode network card uses PCMCIA interface (Personal Computer Memory Card International Association, a standard interface for notebook computers) or CF interface (Compact Flash, a standard interface for notebook computers or other terminal equipment) to communicate with notebook computers or PDAs, etc. Connect and supply power through this interface, and the power supply capacity of the interface is limited. The current consumed when WLAN and GPRS work at the same time will cause the interface to be in a state of high current, and long-term work will cause damage to the interface.

[0008] 2. The larger power consumption of the dual-mode network card will generate more heat, which will cause the network card to heat up, causing the network card and the laptop to work abnormally, resulting in crash or damage

[0009] 3. When the user uses battery power, the large power consumption of the dual-mode network card will greatly reduce the working time of the notebook computer, which will cause inconvenience to the user

[0010] From the above analysis, it can be seen that the control methods of the above two modes have their own defects, which will cause inconvenience to users or cause other problems when using them, which is not conducive to the promotion of operators' business and the development of the industry.
