Abstract: Aspects of the subject disclosure include, for example, identifying a primary serving cell and a secondary serving cell, wherein the primary serving cell facilitates one of attachment, re-attachment or mobility, or any combination thereof, of a mobile device in association with coordination of a wireless service between the primary serving cell, the secondary serving cell and the mobile device. A latency value associated with a message exchange is determined between the primary and secondary serving cells via a messaging interface, and compared to latency requirements, which correspond to a group of mobile service features. A mobile service feature of the group is associated with the wireless service based on the comparison. The wireless service includes a coordinated exchange of wireless signals between the primary serving cell and the mobile device and between the secondary serving cell and the mobile device based on the mobile service feature. Other embodiments are disclosed.

Abstract: When frequency range 1 (FR1) (e.g., Sub6 Ghz radio coverage), and FR2 (e.g., mmW coverage) are present in a given area, there can be a broader coverage from FR1 broadcasting in addition to targeted coverage from FR2 broadcasting. Consequently, FR1 can overlap FR2. To generate system efficiencies, the FR1 and FR2 spectrums can be combined by carrier aggregation (CA) and/or dual connectivity (DC). Thus, a hybrid approach can combine use of both CA and DC, based on radio access network instructions and radio frequency conditions experienced by a user equipment device as it transitions between CA and DC coverage areas.

Abstract: Information used for establishing an initial connection with a network device is optimizable. For example, a system can comprise transmitting a service request to a network node device to establish a connection, receiving a device capability request message comprising a group of configuration parameters that comprise a bandwidth class, a component carrier parameter and a band type parameter, and in response to the receiving the device capability request message, transmitting a device capability report generated based on the group of configuration parameters.

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: Aspects of the subject disclosure may include, for example, obtaining configuration update messages received from neighbor cells of a serving cell of a wireless network, wherein the configuration update messages include dual connectivity capability information of the neighbor cells. The neighbor cells are ranked according to the dual connectivity capability information resulting in a dual connectivity ranking. A target cell of the neighbor cells is selected according to the dual connectivity ranking and a dual connectivity capability of a mobile device, and a dual connectivity service is established according to the dual connectivity ranking. The dual connectivity service includes exchanging user plane messages between the mobile device, a master cell and a secondary cell of the wireless network. Other embodiments are disclosed.
