Study on continuity of data sessions to local networks
The present document studies use cases and potential requirements for Continuity of Data Sessions of a UE to Local Networks.
Local IP Access (LIPA) signifies the capability of a UE to obtain access to a local residential/enterprise IP network (subsequently called a local network) that is connected to one or more H(e)NBs and to communicate with entities in the local network through Data Sessions. Basic functionality for Local IP Access (LIPA) has been specified in 3GPP
Rel-10.
The current study item investigates extending LIPA functionality to allow access to the local network when a UE is under coverage of the macro network and provide related mobility support.
