| 摘要 |
The present invention concerns a local mobile access network, of the kind that comprises a distribution network (RDL) formed by a plurality of nodes (NIE), each node (NIE) being connected to a concentrator (CTR) which is connected to at least one radio terminal (BR) designed to communicate with mobile units linked with said terminal (BR), at least one of said nodes (NIE) of said distribution network (RDL) being connected via routing equipment (PONT) [bridge] to a virtual channel switch (VCX).This network is characterized therein that each virtual connection established between a mobile unit and said switch (VCX) is identified for the entire duration of the communication, no matter which radio terminal (BR) is connected to said mobile unit, by a unique virtual channel identifier (VCI) for the user cell and a unique virtual channel identifier (VCI) for the signalling cells and therein that, during the hand-over phases when a mobile unit is connected to two radio terminals (BR), said two terminals (BR) can exchange information which is then transmitted by cells carrying the signalling channel identifier (VCI) allocated to said mobile unit.
