CONNECTION ESTABLISHMENT IN A WIRELESS TELECOMMUNICATIONS NETWORK

摘要

A wireless telecommunications system comprises a radio network layer which provides the means to carry mobile-specific signalling, and a transport layer which establishes user channels between system nodes over a transport network. The transport network is visible to the radio network layer only via a primitive interface through which it can request transport services. The invisibility of the transport network to the radio network layer makes the radio network layer independent of the underlying transport network and enables the use of different transport network technologies. The radio network layer signalling procedures and connections are mapped with the underlaying transport layer signalling procedures and connections by using binding information. The binding information is provided in a system node (A) at one end of the connection leg, exchanged between the network and transport layers in addition to other necessary parameters through a primitive interface, and used to "identify" the radio network layer and the transport layer connection setup signalling carried out between the nodes.
