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
At least one non-transitory computer-readable medium, carrying instructions that, when executed by at least one data processor, performs a method comprising:
- obtaining at least two attributes associated with a UE operating within a wireless cellular network having multiple 4G and 5G sites, wherein the at least two attributes include
- a battery power remaining in the UE,
- a latency associated with an application running on the UE,
- upload (UL) or download (DL) requirements of the UE,
- a mobility or speed of the UE,
- a UE thermal indicator, or
- a device type of the UE;
- selecting a secondary cell group in an E-UTRAN New Radio-Dual Connectivity (ENDC) group,
- wherein the ENDC group includes a primary cell group and the secondary cell group,
- wherein the primary cell group associated with the ENDC group provides a 4G cellular network connection via a 4G site,
- wherein the secondary cell group includes at least two 5G sites managed by the 4G site in the ENDC group, and
- wherein the selecting includes:
- obtaining at least two priorities associated with the at least two attributes to determine a high priority attribute,
- wherein the device type of the UE is an attribute of the at least two attributes,
- wherein the device type of the UE indicates a capability of the UE to connect to a 5G site, and
- selecting one 5G site in the secondary cell group to provide a 5G cellular network connection to the UE based at least in part on the least one high priority attribute.

- wherein the secondary cell group includes at least two 5G sites managed by the 4G site in the ENDC group, and
- wherein the selecting includes:
- obtaining at least two priorities associated with the at least two attributes to determine a high priority attribute,
- wherein the device type of the UE is an attribute of the at least two attributes,
- wherein the device type of the UE indicates a capability of the UE to connect to a 5G site, and
- selecting one 5G site in the secondary cell group to provide a 5G cellular network connection to the UE based at least in part on the high priority attribute.
