Abstract: A mobile network is analyzed to determine outage regions for a dual-connectivity functionality that uses multiple wireless technologies provided by non-collocated network sites. In some examples, a network configuration server receives and analyzes the locations of base transceiver stations (BTSs) within the mobile network, along with the coverage ranges and wireless technologies supported by the BTS network sites. Based on the analyses, the network configuration server determines regions within which certain dual-connectivity functionality is and is not supported for user equipment (UE) devices. The network configuration server may calculate the outage region for a BTS network site based on the distances between the BTS network site and other BTS network sites providing different wireless technologies for the dual-connectivity functionality. Various elements of the mobile network, including the BTS network sites and/or user mobile devices, may be configured based on the determined outage regions.
