Quick network finding method, system and mobile terminal

Abstract

The invention discloses a quick network finding method, system and mobile terminal, relating to the field of mobile communication. The method comprises the following steps: a personal computer (PC) with a Windows 8 system generates a network searching instruction for searching for a network in full band or limited band according to a user request, and sending the network searching instruction to a mobile terminal for surfing the Internet; the mobile terminal performs network searching in full band or limited band according to the network searching instruction; in the case of full-band network searching, the mobile terminal performs network searching in all supported bands and sends the network searching results to the PC; and in the case of limited-band network searching, the mobile terminal reads the signed network information in an SIM (subscriber identity module) card and signed with an operator of the SIM card, searches for the corresponding network according to the signed network information and sends the network searching results to the PC. According to the invention, the mobile terminal can quickly find a network and has a strong real-time property.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method, system and mobile terminal for quickly finding a network. Background technique [0002] PC is the carrier of wireless data terminal, and the operating system installed on it is also constantly changing and developing, and Windows 8, as a new generation of Windows operating system to be launched by Microsoft, has revolutionary significance. The system aims to make people's daily computer operations easier and faster, and provide people with an efficient and easy working environment. The Windows8 system introduces a new feature of class driver ClassDriver. ClassDriver is a network card management model developed by Microsoft based on the network control model CDC NCM based on the classification of communication equipment. It is a further development of the network driver interface specification NDIS6.2 and RNDIS; on the Windows8 system, Compatible with wireless termin...

Problems solved by technology

[0004] (1) When the mobile terminal searches the network, it will search all the supported frequency bands, resulting in a long search time; and because many of the networks found are not the contracted network of the SIM card operator of the customer identification module, the terminal is in the network. It is not possible to register on these networks, and the end user is presented with the result of not being able to register

It often happens that multiple networks cannot be registered, which seriously affects the registration time of the terminal, and also seriously affects the user experience of the terminal

[0005] (2) The search sequence of the mobile terminal and the wireless access technology used are written into the SIM card, but after the SIM card is issued to the user, it cannot be modified, resulting in the failure of the wireless access technology expected by the user, affecting the user experience;

[0006] (3) For each operator, not all frequency bands are supported, and generally only one or two frequency bands are used. However, when mobile terminals search for the network, they will search for all frequency bands, resulting in slow network search time, especially in the global The connection is getting closer and closer, users frequently travel between different countries, and the frequency bands used by each country are inconsistent. It is impossible for users to set the frequency band according to the local network environment, so it is more likely to have slow network search at this time, which affects user experience.

[0008] On the other hand, due to operating system reasons, systems before Windows 8 do not have the ClassDriver feature and cannot provide a dedicated ClassDriver channel for the transmission of control commands, and there is no mechanism for automatically issuing control commands between the system and the terminal. The way to find the network, etc., the implementation method is very complicated, and the interaction with the upper PC side software (such as UI) is also relatively cumbersome
