Network access method and mobile terminal

Abstract

An embodiment of the invention discloses a network access method. The method comprises the following steps of detecting information of a target user identity identification card which is inserted into a mobile terminal and determining whether the target user identity identification card is included in at least one user identity identification card prestored by the mobile terminal; if the target user identity identification card is not included in at least one user identity identification card prestored by the mobile terminal, determining all the network types supported by the target user identity identification card according to the type of the target user identity identification card, determining network identifications of public land mobile networks PLMN of all the network types and adding the network identifications of the PLMNs of all the network types into an equivalent home network EHPLMN list; when the mobile terminal arrives at a visiting place from a specific location and begins to search a network, if a target PLMN which matches with the network identification in the EHPLMN list is searched, establishing communication connection between the mobile terminal and the target PLMN. Through implementing the embodiment of the invention, time for the mobile terminal to connect the public land mobile network can be reduced so that a user communication experience of the mobile terminal is greatly increased.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a network access method and a mobile terminal. Background technique [0002] Public Land Mobile Network (PLMN, PublicLandMobileNetwork) is a network established and operated by the government or its approved operators to provide land mobile communication services for the public. This network is usually interconnected with the public switched telephone network to form an entire regional or national scale communication network. [0003] The identification of the public land mobile network is usually a series of digital codes. For example, the network identification of China Mobile's PLMN is 46000, and the network identification of China Unicom's PLMN is 46001. Users can communicate conveniently and quickly through the mobile networks provided by various operators. With the improvement of people's living standards, more and more users carry communication terminal equipment. Net...

Problems solved by technology

[0004] However, in the prior art, when a mobile phone searches for a network, it needs to continuously search the network, and the mobile phone needs to try to connect to the found network. Only by continuously trying to connect until it finds a network type supported by the mobile phone can the network access be performed. Networking takes a long time. Long, the mobile phone keeps trying to connect to the network, which consumes a lot of power and the user's communication experience is low
