Embodiment Construction

[0043] Embodiments of the present invention will be described below with reference to the drawings. Elements and features described in one drawing or one embodiment of the present invention may be combined with elements and features shown in one or more other drawings or embodiments. It should be noted that representation and description of components and processes that are not related to the present invention and known to those of ordinary skill in the art are omitted from the drawings and descriptions for the purpose of clarity.

[0044] This application is to solve the problem of unstable communication of the single card module, and to increase the switching mechanism of other operators, and at the same time, perform simple prediction on the network signal to be switched, avoid unnecessary invalid switching, and improve real-time performance. At the same time, it solves the problem that multiple SIM cards need to be inserted into the multi-card multi-link communication modu...

Abstract

The invention discloses a reliable switching method and device for a communication module network. The method comprises the steps: enabling one link of a communication module to serve as a working link, enabling one link of the communication module to serve as a detection link, and enabling the communication module to support double-card double-link or multi-card multi-link; wherein the working link is used for a data channel for normal work of the communication module, and the detection link is used for detecting the quality of a new operator network signal without actually logging in a new operator network; when the working link is abnormal in communication, the detection link selects a proper signed operator as a selected operator based on a detection result of the detection link, initiates connection to the selected operator actively, and switches the functions of the working link and the detection link mutually, so that the original working link is changed into the detection linkto serve as a detection channel for the next round of switching; an original detection link is changed into a working link and is responsible for normal data communication of the communication module.Through the implementation scheme of the two links, the problem of unstable communication of the single-card module is solved, switching mechanisms of other operators are increased, Meanwhile, simplepre-judgment is performed on the network signal to be switched, so that unnecessary invalid switching is avoided, and the real-time performance is improved.

Description

technical field [0001] The invention relates to the application of USIM in the operation of GSM 2G, 3G and 4G telecommunication networks in the field of digital communication, in particular to a reliable switching method and device for realizing communication module networks. Background technique [0002] SIM / USIM card is (Subscriber Identification Module), also known as subscriber identification card, smart card, GSM / CDMA digital mobile phone must be equipped with this card before it can be used. [0003] The digital mobile phone customer's information, encrypted key and user's phone book are stored on the computer chip, which can be used to identify the identity of the GSM / CDMA network customer and encrypt the voice information of the customer during the call. [0004] SIM is made up of CPU, ROM, RAM, EEPROM and I / O circuit. When the user uses the SIM, the mobile phone actually sends commands to the SIM card, and the SIM card should execute or reject it according to stand...
