Abstract: 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.

Abstract: PURPOSE: A method for controlling an ATM switch having an open-type structure within an RNC(Radio Network Controller) of a mobile communication system is provided to enable an additional function, and to add an interface function only with a GSMP(General Switch Management Protocol) of a control processor, without influencing an independent model function when replacing with a common ATM switch, thereby easily interworking with an open-type ATM switch. CONSTITUTION: An RNC sets a switch model identifier, and requests a connection setup/cancellation of an ATM switch control block(410). The ATM switch control block assigns necessary parameter values according to the switch model identifier(420), and distinguishes the switch model identifier. If the switch model identifier is a GSMP-based independent model, the control block directly transmits an IPC message used during inter-processor communication in a GSMP-based independent model ATM switch, and performs a switch control function(430). If connected to a GSMP complying switch, the block converts an IPC type into a message type(450), and transmits an additional message to a switching processor(460). A GSMP message is encapsulated(470). The additional message is supplied with a function, depending on whether the GSMP complying switch(480).

Abstract: PURPOSE: An inter-RNC(Radio Network Controller) connection method in a radio communication system is provided to efficiently transmit a bearer by using a minimum of ATM(Asynchronous Transfer Module) address resources between an RNC and an RNC in a handover and reducing the load of an interface module. CONSTITUTION: A serving RNC determines a VPI(Virtual Path Identifier) value for bearer allocation for inter-RNC connection. Using the determined VPI value, a G-RNC(Global-RNC) reads the address of the cell transmitted from the serving RNC and determines an output port to route to a drift RNC.

Abstract: PURPOSE: A traffic control method of a random access channel in an asynchronous mobile communication system is provided to constantly use a random access channel at a required level of power and minimize an influence to a different channel by using the random access channel as a frame structure, discriminating signatures by request transfer rate spreading factor of several groups and rendering a base station to control a channel use on the basis of information on the number of preambles transmitted to a previous frame. CONSTITUTION: Each radio mobile terminal which has generated a packet to be transmitted obtains a channel through a preamble transmission. In order to reduce a packet collision, the radio mobile terminal selects one of signatures, that is, 16 orthogonal code, selects one of 8 slots existing in the generated frame and transmits a preamble. A base station receives the preamble properly transmitted without a collision or other error, and if a channel use of the used signature is available, the base station transmits a positive ACK signal through the obtained instruction channel to transmit the signature used by the mobile terminal to a down channel. If the channel of the signature being used is not available due to a blocking, the base station transmits a negative ACK signal to transmit a signal obtained by multiplying the used signature by -1. If the base station receives a positive ACK signal from the obtained instruction channel, the base station transmits a data packet by using an orthogonal code for spreading factor corresponding to the used signature. By operating the random access channel, a collision frequently taking place in the channel due to the slotted ALOHA characteristics can be minimized.
