Abstract:
A method for establishing packet data services in a telecommunications system, said method comprising the steps of:establishing a MAC layer connection between a first and second transceiver, said second transceiver associated with one of a plurality of base stations; establishing a plurality of virtual connections for said MAC layer connection, each of said plurality of virtual connections established with one of said plurality of base stations and each associated with a separate MAC_ID; receiving packet data at said MAC layer in said first transceiver, said packet data received from a ink layer; determining, in response to receiving said packet data, whether a first traffic channel from said first transceiver to said second transceiver has been established for carrying circuit switched communications between a multiplex layer of said first transceiver and a multiplex layer of said second transceiver prior to establishment of said MAC layer connection; and if it is so determined, establishing at least one second traffic channel between said multiplex layer of said first transceiver and said multiplex layer of said second transceiver, controlling multiple access of said packet data to said multiplex layer of said first transceiver through said MAC layer, and multiplexing said circuit switched communications and said packet data on said first traffic channel and said packet data on said at least one second traffic channel through said multiplex layer; else, if it is determined that a first traffic channel has not been established, establishing a first traffic channel and at least one second traffic channel between said multiplex layer of said first transceiver and said multiplex layer of said second transceiver, controlling multiple access of said packet data to said multiplex layer through said MAC layer, and multiplexing said packet data onto said first traffic channel and said at least one second traffic channel through said multiplex layer.
