Network access method and mobile communication terminal

Abstract

An embodiment of the invention discloses a network access method comprising the following steps: a mobile communication terminal reads order information and acquires visited information from the order information, wherein the order information includes visited information; the mobile communication terminal judges whether the network identity of a visited PLMN exists in an EPLMN list according to the visited information, wherein the network identity of the visited PLMN is associated with the visited information; the mobile communication terminal adds the network identity of the visited PLMN to the EPLMN list if the network identity of the visited PLMN does not exist in the EPLMN list; and the mobile communication terminal accesses a network according to the EPLMN list. According to the method of the invention, a terminal can acquire a VPLMN in shared network information from a server according to order information and add the VPLMN to an EPLMN list. When the terminal searches a network according to the EPLMN list, the length of time for network search by the terminal can be reduced as the network identity of a registered public land mobile network is equivalent to the network identity of a visited PLMN.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a network access method and a mobile communication 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 us...

Problems solved by technology

[0004] When a mobile communication terminal moves from the place of origin to the place of visit (for example, the mobile communication terminal roams from the home country to the visiting country), the mobile communication terminal needs to access the public land mobile network PLMN of the current home place. When a communication terminal moves from a place of origin to a place of visit, it often takes a long time (sometimes even more than tens of minutes) for the mobile communication terminal to successfully access the public land mobile network of the place of visit.
