Dynamic steering across non-standalone and standalone network architectures based on uplink throughput requirements
Aspects of the present disclosure a method for dynamic steering across non-standalone and standalone network architectures based on uplink throughput requirements is provided. The method begins with determining if at least one UE is active on an SA layer. A determination is then made whether the UE has only non-guaranteed bit rate data bearers with no voice and delay sensitive bearers. The uplink buffer threshold for the at least one UE is then compared with an operator defined uplink buffer threshold. Next, a comparison is made with an uplink throughput estimate on the SA and an uplink throughput estimate for the at least one UE on an NSA layer is made. If the NSA layer has a higher uplink throughput estimate than the SA layer, a dynamic handover is performed from the SA layer to the NSA layer.
1. A method of dynamic steering across non-standalone (NSA) network segments and standalone (SA) layers in a network, the method comprising:
determining if at least one user equipment (UE) is active on a SA layer;
based on the determining that at least one UE is active on the SA layer, determining if the at least one UE has only non-guaranteed bit rate data bearers with no voice and delay sensitive bearers;
based on the determining that the at least one UE has only non-guaranteed bit rate data bearers with no voice and delay sensitive bearers, determining if an uplink buffer threshold requirement for the at least one UE is higher than an operator defined buffer threshold;
based on the determining that the uplink buffer threshold requirement for the at least one UE is higher than the operator defined buffer threshold, comparing an uplink throughput estimate for the at least one UE on the SA layer with an uplink throughput estimate for the at least one UE on a NSA layer;
based on the comparing, determining if the NSA layer uplink throughput is higher than the SA layer uplink throughput; and
based on the determining that the NSA layer uplink throughput is higher than the SA layer uplink throughput, dynamically triggering a handover of the at least one UE from the SA layer to the NSA layer.
2. The method of claim 1 , wherein the at least one UE connects to the SA layer through a new radio (NR) base station.
3. The method of claim 1 , wherein the at least one UE connects to the NSA layer through a new radio (NR) base station and a long-term evolution (LTE) base station.
4. The method of claim 3 , wherein the LTE base station serves as a master base station.
5. The method of claim 4 , wherein the NR base station serves as a secondary base station.
6. The method of claim 1 , wherein the comparison of uplink buffer throughput estimates is based on co-located SA and NSA layers.
7. The method of claim 1 , wherein the comparison of uplink buffer throughput estimates is based on non-co-located SA and NSA layers.
8. The method of claim 1 , wherein the handover is further based on whether the handover would overload one radio access technology.
9. A non-transitory computer storage media storing computer-useable instructions that, when used by one or more processors, cause the processors to:
determine if at least one user equipment (UE) is active on a SA layer;
based on the determination that at least one UE is active on the SA layer, determine if the at least one UE has only non-guaranteed bit rate data bearers with no voice and delay sensitive bearers;
based on the determination that the at least one UE has only non-guaranteed bit rate data bearers with no voice and delay sensitive bearers, determine if an uplink buffer threshold requirement for the at least one UE is higher than an operator defined buffer threshold;
based on the determination that the uplink buffer threshold requirement for the at least one UE is higher than the operator defined buffer threshold, compare an uplink throughput estimate for the at least one UE on the SA layer with an uplink throughput estimate for the at least one UE on a NSA layer;
based on the comparison, determine that the NSA layer uplink throughput is higher than the SA layer uplink throughput; and
based on the determination that the NSA layer uplink throughput is higher than the SA layer uplink throughput, dynamically trigger a handover of the at least one UE from the SA layer to the NSA layer.
10. The non-transitory computer storage media of claim 9 , wherein the at least one UE connects to the SA layer through a new radio (NR) base station.
11. The non-transitory computer storage media of claim 9 , wherein the at least one UE connects to the NSA layer through a new radio (NR) base station and a long-term evolution (LTE) base station.
12. The non-transitory computer storage media of claim 11 , wherein the LTE base station serves as a master base station.
13. The non-transitory computer storage media of claim 12 , wherein the NR base station serves as a secondary base station.
14. The non-transitory computer storage media of claim 9 , wherein the handover is further based on whether the handover would overload one radio access technology.
