[0004] When the mobile communication terminal returns from the visited place to the home place (for example, the mobile communication terminal returns to the home country from the roaming country), the mobile communication terminal needs to access the public land mobile network PLMN returning to the home place. However, the current situation that often occurs is When a mobile communication terminal moves from a visiting place to a home place, it often takes a long time (sometimes it may even need to wait for more than tens of minutes) before the mobile communication terminal can successfully access the public land mobile network of the current visiting place, which greatly The impact of user communication experience

The invention discloses a network access method comprising the following steps: a mobile communication terminal from a visited location to a home location searches a network in the home location; and if a home PLMN matched with a network identity in an equivalent public land mobile network EPLMN list is searched in the home location, communication connection between the mobile communication terminal and the matching home PLMN is established, wherein the EPLMN list includes the network identity of the home PLMN and the network identity of a visited PLMN, and the network identity of the home PLMN is the network identity of a PLMN of a home operator which signs a roaming agreement with a visited operator. According to the invention, the visited public land mobile network identity and the home public land mobile network identity of the mobile communication terminal in the equivalent public land mobile network list are adopted, and network search is performed in a home public land mobile network mode. The time for network search is reduced effectively, and the efficiency of network search is improved.
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) is a network established and operated by the government or its approved operators to provide land mobile communication services for the public. The network must be interconnected with the Public Switched Telephone Network (PSTN) to form a 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 mobile communication termin...
