Problems solved by technology

[0011] The purpose of the present invention is to provide a method for selecting a network in a network with multiple network numbers in view of the above-mentioned defects caused by multiple network numbers, which can solve the problem of a mobile terminal that does not match the network number of the network broadcast in the multi-network number network logging into the network. Sometimes, the problem of not being able to log in due to the mismatch of network numbers

Embodiment Construction

[0021] The basic principle of the present invention is by setting an EHPLMN file that contains all home networks as the network numbers of the network in the SIM / USIM card, when comparing the network numbers in the IMSI, if there is no matching situation, the EHPLMN file will be included in the EHPLMN file. Compared with the network number of the broadcast network one by one, if there is a network number that matches, it will directly log in to the network, thus solving the problem that the terminal with multiple network numbers does not match the unique network number of the network broadcast in the past, resulting in the inability to log in to the network question.

[0022] As shown in Figure 1, it is a schematic diagram of the system structure of the multi-network number network adopted by the present invention, wherein mobile terminal 1, mobile terminal 2 and mobile terminal 3 are mobile terminals with different network numbers, and they all belong to one operator. The pro...

Abstract

This method includes the following steps. Step 1. When the mobile terminal (MT) exercises the home public land mobile net (HPLMN) match, MT compares the international mobile user identification code with the home net number (HNN) broadcasted by the mobile comm. net (MCN); then judges that they match or not. If they do, step 4 is executed. Otherwise, step 2 is executed. Step 2. MT fetches the preset equity HPLMN document including several HNN. Step 3. From the equity HPLMN document, MT selects the HNN, which matches the HNN broadcasted by MCN. Step 4. MT logs in MCN. Comparing the EHPLMN document stored in SIM/USIM card with the broadcasted net number, this invention eliminates the shortage of that MT with non-broadcasted net number cannot login.

Description

technical field [0001] The present invention relates to a method for selecting a network in a multi-network number network, in particular to a method for enabling a mobile terminal to select a home network to log in by utilizing a peer-to-peer home public land mobile network (EHPLMN) in a multi-network number network. Background technique [0002] When there is only one network number in the network, when the mobile terminal is turned on or roaming, its primary task is to search for the network or re-search the network, and then select an available network to perform the login operation, that is, the network selection operation. The network selection operation of the mobile terminal can be decomposed into two sub-processes: public land mobile network (PLMN) selection and cell search. In the PLMN selection sub-process, the mobile terminal will maintain a list of PLMNs. High-priority downward search, the priority order is: RPLMN (Registered PLMN, the last logged-in PLMN), HPLM...
