Abstract
Today, a device can be simultaneously connected to multiple
communication networks based on different technology implementations
and network architectures like WiFi, LTE, and DSL. In such multi-
connectivity scenario, it is desirable to combine multiple access
networks or select the best one to improve quality of experience for
a user and improve overall network utilization and efficiency. This
document presents the u-plane protocols for a multi access
management services (MAMS) framework that can be used to flexibly
select the combination of uplink and downlink access and core
network paths having the optimal performance, and user plane
treatment for improving network utilization and efficiency and
enhanced quality of experience for user applications.
