Embodiment Construction

[0062] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0063] Such as figure 1 As shown, the embodiment of the present invention provides a network access method applied to a terminal, including:

[0064] Step 11: After the terminal is turned on, check whether the highest level of the air interface access system supported by the terminal is higher than the highest level of the air interface access system supported by the USIM card of the terminal.

[0065] In this step, the levels of the air interface access systems at least include: 2G air interface access systems, 3G air interface access systems, 4G air interface access systems and 5G air interface access systems. For example, the levels of the air interface access system supported by the terminal include: 4G air interface access system and 5G air interfa...

Abstract

The invention provides a network access method and device and a terminal, and the method comprises the steps that whether the highest level of an air interface access system supported by the terminalis higher than the highest level of an air interface access system supported by a global subscriber identity module USIM card of the terminal or not is detected after the terminal is started; and if yes, the terminal selects a network matched with the highest level of the air interface access system supported by the terminal according to the highest level of the air interface access system supported by the terminal and initiates registration. According to the embodiment of the invention, the highest level of the air interface access system supported by the terminal is higher than the highest level of the air interface access system supported by the USIM card; the terminal selects the network matched with the highest level of the air interface access system supported by the terminal and initiates registration, and for a 5G independent networking-oriented scene, card replacement is avoided, and the operation cost of card replacement is omitted.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a network access method, device and terminal. Background technique [0002] USIM card (Universal Subscriber Identity Module) is a smart card used for user identification, and the terminal (such as a smart phone or data terminal) must be equipped with this card before it can be used. Under normal circumstances, the terminal and the USIM card are used together, that is, the highest capacity of the terminal is equal to the highest capacity of the card. For example, for a 4G network, a mobile phone that supports 4G needs to be equipped with a 4G USIM card to access the 4G network for 4G services. [0003] As 4G (LTE, Long Term Evolution) enters the stage of large-scale commercial use, the fifth-generation mobile communication (5G) for 2020 and the future has become a global research and development hotspot. At present, 3GPP defines two schemes for 5G New Radio (NR) ne...
