MOBILE SYSTEM CAPABLE OF CHANGING CHANNEL CARDS AND METHOD FOR CHANGING CHANNEL CARDS
摘要
PURPOSE: A mobile system capable of changing channel cards and a method for changing channel cards are provided to increase the efficiency in use of channel cards and the efficiency of radio access by enabling a channel card in use to be replaced with another channel card. CONSTITUTION: If a UE(User Equipment)(330) makes a call setup request, an RNC(Radio Network Controller) sets up a DCCH logical channel for signal dedicated channel setup for the UE. The RNC determines the capacity of a traffic channel service through the DCCH logical channel. Then the RNC judges whether a change in the channel card connected to the UE by wireless is required. In case that a change in the channel card connected to the UE by wireless is required, an RTS establishes a multipath for another channel card other than the connected channel card. The RTS releases the wireless connection between the UE and the presently connected channel card and connects the UE to the multipath-established channel card by wireless. The RNC releases the connection between the UE and the connection-released channel card and sets up a DTCH logical channel for traffic transmission to the UE.
