Providing for mobility for flexible bandwidth carrier systems

摘要

Methods, systems, and devices for facilitating mobility between flexible bandwidth systems and other bandwidth systems are provided. These tools and techniques that provide mobility between different bandwidth systems may facilitate supporting circuit-switched (CS) services, such as CS voice services. Some embodiments provide for determining flexible bandwidth capable devices, such as user equipment. Some embodiments involve core network redirection where a core network may direct the handling of circuit-switched services when a flexible bandwidth system does not support the CS services. Some examples provide for radio access network determined handling of CS services when a flexible bandwidth system may not support the CS services. Some embodiments provide for transitioning to a flexible bandwidth system. Some embodiments provide for transitioning from flexible bandwidth systems to non-flexible bandwidth systems that have no support for some or all CS services, other flexible bandwidth systems, and/or systems that natively support CS voice services.

主权项

1. A method for providing mobility within wireless communications systems comprising:
communicating with a user equipment using a flexible bandwidth radio access network from a plurality of radio access networks, the flexible bandwidth radio access network including one or more carriers whose bandwidths are scaled; determining that the flexible bandwidth radio access network fails to support data rates used by a circuit-switched service; and determining, by the flexible bandwidth radio access network, to redirect the circuit-switched service for the user equipment to a radio access network that supports the data rates used by the circuit-switched service from the plurality of radio access networks.
