Abstract

The embodiments herein provide a user equipment, chip and method for handling public land mobile network selection. The method includes detecting one of the following when the user equipment has stored a duplicate value of a registered public land mobile network (RPLMN) and a duplicate of a public land mobile network selection mode: prior communication due to proximity-based services Public land mobile network selection resulting from public land mobile network selection is followed by manual closed subscriber group (CSG) cell selection; and public land mobile network selection resulting from short range based service communication is preceded by manual closed subscriber group cell selection. Furthermore, the method includes retaining stored duplicate values ​​of registered public land mobile networks and stored duplicates of public land mobile network selection modes.

Description

technical field [0001] The present invention relates to wireless communications, and more particularly to a User Equipment for handling Public Land Mobile Network (PLMN) selection involving Proximity Based Service (Prose) communications. , UE) and method. Background technique [0002] The principle of proximity based applications and services is to explore instances of applications running in devices in close proximity to each other and eventually exchange application related data also for general and public safety reasons. Proximity-based service direct discovery and Evolved Packet Core (EPC)-level proximity-based service discovery is applicable to public safety user equipment and non-public safety user equipment, and proximity-based service direct communication is only applicable to public Secure User Devices. [0003] As specified in 3GPP TS 24.334 and TS 23.122, the user equipment 100 has to perform public land mobile network selection for short-range based service com...
