Abstract
In 5G Non-Standalone (NSA), to balance the load on 5G users and 4G users effectively, the disclosed technology selects the proper secondary cell group (SCG), when the master cell group (MCG) is provided by 4G infrastructure. E-UTRAN New Radio-Dual Connectivity (ENDC) allows users to connect to a 4G MCG and a 5G SCG (SCG). The technology selects the SCG based on each user's application's attributes such as UL/DL data volume, speed or bandwidth.
Claims20
A method comprising:
- obtaining multiple attributes associated with a user equipment (UE) operating within a wireless cellular network having multiple 4G and 5G sites,
- wherein the multiple attributes indicate a cellular network bandwidth, and
- wherein the multiple attributes include a bandwidth requirement associated with the UE and a speed of motion associated with the UE;
- selecting a secondary cell group (SCG) in an E-UTRAN New Radio-Dual Connectivity (ENDC) group,
- wherein the ENDC group includes a master cell group (MCG) and the SCG,
- wherein the MCG associated with the ENDC group provides a 4G cellular network connection via a 4G site,
- wherein the SCG includes at least two 5G sites managed by the 4G site in the ENDC group, and
- wherein the selecting includes:
- determining one or more bandwidth throughputs associated with the at least two 5G sites and indicating a cellular network bandwidth provided by the at least two 5G sites, and
- selecting one 5G site in the SCG to provide a 5G cellular network connection to the UE based on determining that the speed of motion is below a speed threshold and the bandwidth requirement is below a bandwidth throughput associated with the selected 5G site.
7 more elements
A system comprising:
- one or more processors;
- memory coupled to the one or more processors, wherein the memory includes instructions executable by the one or more processors to:
- obtain multiple attributes associated with a UE operating within a wireless cellular network having multiple 4G and 5G sites,
- wherein the multiple attributes indicate a cellular network bandwidth, and
- wherein the multiple attributes include a bandwidth requirement associated with the UE;
- select an SCG in an E-UTRAN New Radio-Dual Connectivity (ENDC) group,
- wherein the ENDC group includes an MCG and the SCG,
- wherein the MCG associated with the ENDC group provides a 4G cellular network connection via a 4G site,
- wherein the SCG includes at least two sites managed by the 4G site in the ENDC group, and
- wherein selecting a secondary cell includes:
- determine one or more bandwidth throughputs associated with the at least two sites and indicating a cellular network bandwidth provided by the at least two sites;
- and
- select one site in the SCG to provide a cellular network connection to the UE based on determining that the bandwidth requirement is below a bandwidth throughput associated with the selected site.
10 more elements
At least one non-transient computer-readable medium, carrying instructions that, when executed by at least one data processor, performs a method comprising:
- obtaining at least one attribute associated with a UE operating within a wireless cellular network having multiple 4G and 5G sites, wherein the at least one attribute includes—a power remaining in the UE, a latency associated with an application running on the UE, uplink (UL) or downlink (DL) requirements of the UE, a location of the UE, or UE thermal indicator;
- selecting an SCG in an E-UTRAN New Radio-Dual Connectivity (ENDC) group,
- wherein the ENDC group includes an MCG and the SCG,
- wherein the MCG associated with the ENDC group provides a 4G cellular network connection via a 4G site,
- wherein the SCG includes at least two 5G sites managed by the 4G site in the ENDC group, and
- wherein the selecting includes:
- selecting one 5G site in the SCG to provide a 5G cellular network connection to the UE based on an analysis of the least one attribute.
