ENABLING 5G NR NON-STANDALONE E-UTRAN DUAL-CONNECTIVITY VIA DUAL-CONNECTIVITY ROAMING

摘要

The present disclosure describes techniques and systems for enabling fifth generation new radio (5G NR) non-standalone (NSA) evolved universal terrestrial radio access network new radio dual-connectivity (EN-DC) via dual-connectivity roaming. These techniques enable a user device (110) connected to a first service-provider network (602) to dual-connectivity roam onto a second service-provider network (604). The user device (110) can access the second service-provider network (604) (e.g., to support EN-DC in a non-overlapping area of the first service-provider network) while using an anchor link of the first service-provider network (602). In one example, a user device (110) on a Long Term Evolution (LTE) service-provider network (602) can dual-connectivity roam onto a 5G NR service-provider network (604) while using an anchor link of the LTE service-provider network (602) to access the second 5G NR service-provider network (604) and communicate using EN-DC.
