CPC H04W 76/15 (2018.02) [H04W 60/00 (2013.01); H04W 76/19 (2018.02); H04W 76/25 (2018.02); H04W 76/27 (2018.02)] | 8 Claims |
5. A user equipment (UE) for providing 5th generation (5G) services in a wireless communication network, comprising:
a memory; and
a processor coupled to the memory and configured to:
register to a 4G network on a first transceiver and to a 5G network on a second transceiver in a dual registration mode with dual radio,
while the UE is registered to the 4G network on the first transceiver and to the 5G network on the second transceiver, detect an unavailability of a voice over new radio (VOLAR) service and a voice over long term evolution (LTE) (VOLTE) service at the UE, and
in response to detecting the unavailability of the VOLAR service and the VOLTE service at the UE, configure the UE to operate in a single radio LTE (SRLTE) mode on the first transceiver with being registered to the 5G network on the second transceiver, wherein the UE is registered to one of the 4G network and 1× core on the first transceiver in the SRLTE mode,
while the UE operates in the SRLTE mode on the first transceiver with being registered to the 5G network on the second transceiver, initiate 1× voice call on the first transceiver,
in response to initiating the 1× voice call on the first transceiver while the UE operates in the SRLTE mode on the first transceiver with being registered to the 5G network on the second transceiver, determine whether to provide 4G services or 5G services on the second transceiver, and
provide the 4G services or the 5G services based on the determination.
