Abstract: Various embodiments disclosed herein provide for a compressed UE capability message that can indicate to a mobile network the various capabilities of the UE. In particular, the carrier aggregation and dual connectivity capabilities are compressed as disclosed herein. In traditional implementations, each carrier aggregation and dual connectivity combination and implementation that is supported is explicitly indicated in the message. As disclosed herein, rather than listing explicit combinations, the UE capability message can be compressed by instead listing boundary values of several different parameters which can be used by the network to derive the carrier aggregation and dual connectivity combinations. The UE capability message can also list the boundary values for LTE (Long Term Evolution), NR (New Radio, or 5G), and Dual Connectivity separately within the message to reduce ambiguity.

Abstract: A mobile device mobility state is included in device reporting to a radio access network for mobility event and load balancing purposes. Respective load conditions and respective coverage areas of a first set of devices of a first network and a second set of devices of a second network are analyzed. In addition, a mobility state of a mobile device, a first signal strength associated with the first set of devices, and a second signal strength associated with the second set of devices are also analyzed. The mobility state is a function of a movement pattern of the mobile device and a speed at which the mobile device is being moved. Network traffic of the mobile device is routed to a set of network devices selected from the first set of devices and the second set of devices, as a result of the analysis.

Abstract: Data can be sent simultaneously on the data links between long-term evolution (LTE) and new radio (NR) for dual connectively. However, a mobile device can indicate its capabilities to the network. The mobile device capabilities can comprise the number of total multiple-in multiple-out (MIMO) layers that the mobile device can support. Because different sectors or markets can have different spectrums that can make use of an increased or decreased number of layers, then assessing the MIMO layer capabilities of the mobile device can allow the network to dynamically adjust the LTE side and the NR side capabilities to optimize network utilization.
