Problems solved by technology

[0003] Among the USIMs currently in use, since some USIMs did not have a 5G network when they were issued, there is no information about whether the network supports 5G in the list of network selection related public land mobile networks (PLMN, Public Land Mobile Network) configured in this part of the USIM. In the case of a 5G network, these USIMs may not be able to reside on the 5G network at the first time, which may cause the user equipment (UE, User Equipment) using these USIMs to fail to achieve the optimal communication effect

Abstract

The invention relates to a network selection method and device. The method is applied to user equipment supporting a 5G network, and comprises the following steps: determining the type of a universalsubscriber identity module (USIM) according to configuration information of the USIM in the user equipment, the configuration information comprising a current public land mobile network (PLMN) list ofthe USIM; when the USIM is the stock USIM, adding 5G configuration information into the current PLMN list of the stock USIM according to a network access technology supported by the PLMN in the current PLMN list of the stock USIM to obtain an updated PLMN list of the stock USIM; and performing network selection according to the updated PLMN list. By adding the 5G configuration information to thePLMN list of the stock USIM, the user equipment adopting the stock USIM can reside in the 5G network more effectively by adopting the network selection method and device provided by the embodiment ofthe invention.

Description

technical field [0001] The present disclosure relates to the field of 5G communication, and in particular to a network selection method and device. Background technique [0002] Universal Subscriber Identity Module (USIM, Universal Subscriber Identity Module), also called Upgraded SIM, is a component of Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System) 3G network. [0003] Among the USIMs currently in use, since some USIMs did not have a 5G network when they were issued, there is no information about whether the network supports 5G in the list of network selection related public land mobile networks (PLMN, Public Land Mobile Network) configured in this part of the USIM. In the case of a 5G network, these USIMs may not be able to reside on the 5G network immediately, which may cause user equipment (UE, User Equipment) using these USIMs to fail to achieve optimal communication effects. Contents of the invention [0004] In view of...
