US 12,004,078 B2 · Automatic base station discovery, selection, and registration in 5G/6G

Abstract

A searchable, portable network database of base station information can greatly simplify discovery, selection, and registration of user devices on a preferred cell in 5G or 6G. In addition, based on location, the user device can select the base station that is likely to provide the best signal. The network database can provide all of the static system information of the SSB message, which enables prospective user devices to receive downlink messages without searching for the SSB. In addition, the network database can provide all of the static system information contained in the SIB1 message, which enables prospective user devices to transmit uplink messages without searching for the SIB1. Initial synchronization can be obtained by receiving any broadcast from the base station, or by receiving timing signals from a navigation satellite, among other ways. The user device can thereby avoid most or all of the arduous prior-art cell discovery steps.

Dependent claims

Non-transitory computer-readable media in a user device of a wireless network, the media containing instructions that when executed by a computing environment cause a method to be performed, the method comprising:

a) automatically, without human intervention:
i) determining a location of the user device;
ii) receiving or downloading a network database, or a portion thereof, the network database comprising a plurality of entries, each entry comprising location data and system information of a base station associated with the entry;
iii) determining, by searching the network database, a particular base station that accepts new user devices and is closest to the user device;
iv) determining, according to a particular entry associated with the particular base station, a frequency of a broadcast channel of the particular base station and a frequency of a random access channel of the particular base station;
and
v) transmitting, to the particular base station, an entry message requesting access to the wireless network of the particular base station.

4 more elements

A method for a mobile or portable user device to discover and access a base station, the method comprising:

a) automatically, without human intervention:
i) specifying, in an information request, a region;
ii) receiving or downloading a portion of a network database, the portion related to the region;
iii) determining, according to a signal from a GNSS (global navigation satellite system), a location of the user device;
and
iv) determining, from the portion of the network database, a particular base station that is expected to provide a best reception at the location of the user device.
