Abstract
The present disclosure relates to an enhanced session model capable of managing the configuration and the usage of a single packet data unit session, which is an association between a user equipment and a packet data network entity and is composed of multiple transmission bearers between the access network and the core network. The latter comprises a session type manager entity adapted to control the connectivity of these transmission bearers whose assignment is either individual or shared, multiple user plane function entities, a session type database and a control plane function entity. The latter can be functionally separate from the session type manager entity or extended with its functionalities. The user equipment and the user plane function entities are individually extended with the functionalities of, respectively, a user session type extension entity and user plane session type extension entities, which all comprise a respective mapping table dedicated to the assignment.
