A network access method and mobile terminal

Abstract

The embodiment of the present invention discloses a network access method, including: detecting information of a target user identification card inserted into a mobile terminal, and judging whether the target user identification card is included in at least one user identification card pre-stored in the mobile terminal; If the judgment result is no, then determine all network types supported by the target subscriber identity card according to the type of the target subscriber identity card, and determine the network identifiers of the public land mobile networks PLMN of all the network types, and link all the networks The network identification of the type of PLMN is added to the peer-to-peer home network EHPLMN list; when the mobile terminal arrives at the visiting place from the specified location and starts to search for the network, if the target PLMN matching the network identification in the EHPLMN list is found after searching, the mobile terminal and the EHPLMN list are established. A communication connection between the target PLMNs. The implementation of the embodiments of the present invention can reduce the time for the mobile terminal to connect to the public land mobile network, thereby greatly improving the user communication experience of the mobile terminal.

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, Public Land Mobile Network) is a network established and operated by the government or its approved operators for the purpose of providing 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 ter...

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
