Multi-RAT Dual Connectvity
Systems, methods and computer software are disclosed for providing dual connectivity between different Radio Access Technologies (RATs). In one embodiment a method is disclosed, comprising: anchoring a User Equipment (UE) at a first RAT base station in a first RAT core; using a second RAT base station to supplement the first RAT core; and providing dual connectivity between the first RAT and the second RAT.
1 . A method for providing dual connectivity between different Radio Access Technologies (RATs), comprising:
anchoring a User Equipment (UE) at a first RAT base station in a first RAT core;
using a second RAT base station to supplement the first RAT core; and
providing dual connectivity between the first RAT and the second RAT.
2 . The method of claim 1 wherein anchoring a UE at a first RAT core includes anchoring the UE at one of a 2G core, 3G core or a 4G core, and wherein the second RAT base station is a 5G gNB.
3 . The method of claim 2 wherein anchoring the UE at a 4G core is enhanced using MOCN.
4 . The method of claim 1 further comprising enabling local breakout of typical user traffic.
5 . The method of claim 1 wherein the first RAT is 3G and the second RAT is 4G.
6 . The method of claim 1 wherein the first RAT is 2G and the second RAT is 3G or 5G.
7 . A non-transitory computer-readable medium containing instructions for providing dual connectivity between different Radio Access Technologies (RATs) which, when executed, causes wireless network devices to perform steps comprising:
anchoring a User Equipment (UE) at a first RAT base station in a first RAT core;
using a second RAT base station to supplement the first RAT core; and
providing dual connectivity between the first RAT and the second RAT.
8 . The computer-readable medium of claim 7 further comprising instructions wherein anchoring a UE at a first RAT core includes anchoring the UE at one of a 2G core, 3G core or a 4G core, and wherein the second RAT base station is a 5G gNB.
9 . The computer-readable medium of claim 8 further comprising instructions wherein anchoring the UE at a 4G core is enhanced using MOCN.
10 . The computer-readable medium of claim 7 further comprising instructions for enabling local breakout of typical user traffic.
11 . The computer-readable medium of claim 7 further comprising instructions wherein the first RAT is 3G and the second RAT is 4G.
12 . The computer-readable medium of claim 7 further comprising instructions for wherein the first RAT is 2G and the second RAT is 3G or 5G.
13 . A system for providing dual connectivity between different Radio Access Technologies (RATs), comprising:
a HetNet gateway (HNG);
a first base station in a first RAT in communication with the HNG;
a second base station in a second RAT in communication with the HNG and the first base station;
a User Equipment (UE) in communication with the first base station and the second base station;
wherein the UE is anchored at the first RAT base station in the first RAT core;
wherein the second RAT base station supplement the first RAT core; and
wherein dual connectivity is provided between the first RAT and the second RAT.
14 . The system of claim 13 wherein the UE is anchored at one of a 2G core, 3G core or a 4G core, and wherein the second RAT base station is a 5G gNB.
15 . The system of claim 14 wherein the UE is anchored at a 4G core and is enhanced using MOCN.
16 . The system of claim 13 wherein local breakout of typical user traffic is provided.
17 . The system of claim 13 wherein the first RAT is 3G and the second RAT is 4G.
18 . The system of claim 13 r wherein the first RAT is 2G and the second RAT is 3G or 5G.
