Problems solved by technology

The UE will experience the triangular circular movement of "PLMN A->PLMN B->PLMN C->PLMN A" in the visiting place, causing unnecessary network switching and background scanning, resulting in low network selection efficiency, and further, frequent network Switching and excessive background scanning will greatly consume the power of the user device, resulting in poor roaming user experience

Abstract

Embodiments of the present invention provide a method and device for selecting a network in a visited location. The method includes: a user equipment UE receiving visited network information sent by a home network device of the UE, and the visited network information includes information about at least one network. Identification; the UE selects an available network in the at least one network. The method and device for selecting a network in a visited location provided by the embodiments of the present invention can improve the efficiency of network selection, reduce power consumption of user equipment, and thereby improve user experience in roaming locations.

Description

technical field [0001] The embodiments of the present invention relate to communication technologies, and in particular to a method and device for selecting a network in a visited place. Background technique [0002] The 3rd Generation Partnership Project (3GPP for short) organization defines a network selection strategy for a mobile terminal in an idle state, that is, a strategy for selecting a Public Land Mobile Network (PLMN for short). Both roaming and non-roaming scenarios are covered. [0003] In a roaming scenario, a user equipment (User Equipment, referred to as UE) needs to choose to visit a public land mobile network (Visited PLMN, referred to as VPLMN), and usually adopts an automatic network selection mode: the UE maintains multiple PLMN lists, and each PLMN list in each PLMNs are sorted by priority; when network selection is required, the UE selects available networks in the order of multiple PLMN lists, and when selecting a network in a PLMN list, selects the ...
