Abstract:
A method for cell selection and/or cell reselection handling includes: performing, by a user equipment, a cell selection and/or cell reselection procedure wherein both a first radio cell and a second radio cell fulfill a cell selection criterion with the first radio cell being prioritized relative to the second radio cell; attempting, by the user equipment, to connect to a public land mobile network using a random access channel of a first base station entity, and failing to connect to the public land mobile network using the random access channel of the first base station entity; and performing, by the user equipment, a modified cell selection and/or cell reselection procedure, under unchanged radio conditions, whereby the user equipment attempts to connect to the public land mobile network using a random access channel of the second base station entity.
