System level procedures and methods to enable data sharing in cellular network
Abstract
Methods and systems may enable the setup and configuration of proximity services between wireless transmit/receive units (WTRUs) over different sharing paths including via a direct air interface, a radio access network (RAN) or one or more network nodes. Mobility management entities (MMEs) may exchange messages to initiate, modify or terminate a proximity service session between WTRUs, and may negotiate data paths for proximity services with or without the assistance of WTRUs. WTRU-to-WTRU control plane messages may be exchanged between WTRUs with limited involvement from other network entities and may avoid the setup of resources for data plane communications. Mobility management entities (MMEs) may exchange messages to initiate, modify or terminate a proximity service session between WTRUs, and may negotiate data paths for proximity services with or without the assistance of WTRUs.
