Embodiment Construction

[0027] In order to solve the problem in the prior art, mobile terminals can only select RATs to register with EHPLMN in turn by using the specified RAT priority. Even if other RATs can access the network more stably and quickly, they cannot directly switch to other RATs, which may cause waste of network resources. , the problem that affects the user experience, the embodiment of the present invention provides a network registration method, the specific processing flow is as follows figure 1 shown, including:

[0028] Step 101, the mobile terminal determines that it needs to search for a network to register;

[0029] Step 102, the mobile terminal sequentially executes each of the registration information items stored in itself according to the order of priority from high to low, until the registration is successful;

[0030] Step 103 , for the currently selected item, use the RAT included in the item to identify the corresponding RAT, and register on the EHPLMN corresponding t...

Abstract

The invention discloses a network registering method. The method comprises the following steps of: when a mobile terminal carries out network registration, executing the following operation until the registration is successful, namely sequentially executing each item in each registration information item stored in the mobile terminal according to an order of priorities of the items from high to low; and aiming at the current selected item, registering on an equivalent home public land mobile network (EHPLMN) corresponding to an EHPLMN identifier contained in the current selected item by utilizing a radio access technology (RAT) corresponding to an RAT identifier contained in the item. The embodiment of the invention also provides another network registering method and two mobile terminals. Due to the adoption of the network registering methods and the mobile terminals, the problem that the waste of network resources can be caused possibly and the feeling experience of a user can be influenced because the mobile terminal can only utilize the designated RAT priorities to select RATs sequentially to carry out registration on the EHPLMN and cannot be directly switched to other RATs even though a network can be more stably and rapidly accessed by other RATs in the prior art can be solved.

Description

technical field [0001] The invention relates to the communication field, in particular to two network registration methods and two mobile terminals. Background technique [0002] During the evolution process of the mobile communication system from 2G (2nd Generation, 2nd generation) to 3G (3rd Generation, 3rd generation), each operator may have several sets of RAT (Radio Access Technology, radio access technology) Network, in order to facilitate the mobile terminal to select different RATs to access different networks, the RAT is used as a supplement to the PLMN (Public Land Mobile Network, public land mobile network) identification during the network search process of the mobile terminal. [0003] In the LTE (Long Term Evolution, long-term evolution) system, compared with the previous mobile communication system, the EHPLMN (Equivalent Home Public Land Mobile Network, Equivalent Home Public Land Mobile Network) list is introduced, and the introduced EHPLMN list is used to p...
