    Abstract: The disclosed technology is directed towards switching the primary cell in a carrier aggregation scenario to improve performance. Measurement data of a mobile device (user equipment) is evaluated with respect to one or more various criteria such as cell carrier bandwidth, cell carrier load, cell-related capability and other carrier data (e.g., dynamic spectrum sharing versus clean, time division duplex or frequency division duplex), and others. Device conditions such as overheating can be considered as well. The evaluation results in a ranking of primary cell candidates. If a more optimal primary cell (candidate) is available, the primary cell in the carrier aggregation combination is switched to the candidate that is ranked the highest. Switching can be relatively very fast, such as based on already existing layer-1 (L1) and/or layer-2 (L2) measurement data. Layer-3 (L3) measurement data also can be obtained on demand, for example, to use in the evaluation.

    Abstract: Facilitating application and/or traffic status aware intelligent carrier aggregation in advanced networks is provided herein. Operations of a method can comprise analyzing a traffic usage parameter of a mobile device and, based on a first determination that the traffic usage parameter consumes more uplink resources than downlink resources, configuring, the mobile device with an uplink carrier aggregation based on a first maximization of the uplink carrier aggregation and, thereafter, configuring the mobile device with an allowable downlink carrier aggregation. Alternatively, based on a second determination that the traffic usage parameter consumes more downlink resources than uplink resources, configuring the mobile device with a downlink carrier aggregation based on a second maximization of the downlink carrier aggregation and, thereafter, configuring the mobile device with an allowable uplink carrier aggregation. The uplink carrier aggregation and the downlink carrier aggregation can be non-static carrier aggregations.

    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.
