Samsung patents phone logic to ignore network bans from other carriers

Patent drawing from the official filing.

Samsung has patented a method for 5G and 6G phones to handle network restrictions. When a phone receives a list of areas where it is banned from connecting, it checks if those areas belong to its current carrier. If the ban is from a different carrier, the phone ignores it; if it is from its own carrier, it saves the ban.

Why it mattersThis improves how phones manage network connections by ensuring they only respect restrictions from the specific carrier they are using, rather than getting confused by data from other networks.

In the filing’s own words

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate.

What exactly they claim (claim 1)

1. A method performed by a terminal in a wireless communication system, the method comprising: receiving, from an access and mobility management function (AMF), a message comprising information on forbidden tracking areas; identifying whether at least one tracking area identity (TAI) in the information belongs to a serving public land mobile network (PLMN) or an equivalent PLMN; in case that the at least one TAI in the information belongs to the serving PLMN or the equivalent PLMN, storing the at least one TAI; and in case that the at least one TAI in the information does not belong to the serving PLMN or the equivalent PLMN, ignoring the at least one TAI.
