The present invention relates to a RAB setting method in an asynchronous mobile communication system, and more particularly, to an RAB setting method in an asynchronous mobile communication system for shortening a call connection time in an asynchronous mobile communication system.

A general call processing procedure in an asynchronous mobile communication system is described with reference to FIG. 1 as follows.

First, when the calling mobile communication terminal attempts to connect a call, the calling mobile communication terminal and the calling radio network controller (RNC) establish a signaling radio bearer (hereinafter referred to as 'SRB') for transmitting and receiving signaling messages. (RRC Connection setting process) (S11).

Step S11 is a process of establishing a passage for transmitting and receiving a message between the calling mobile communication terminal and the mobile communication system, and all call processing starts from the RRC (Radio Resource Control) connection establishment process.

When the SRB setup process is completed in step S11, the originating mobile communication terminal transmits a service request message to the mobile communication system through the signaling channel configured in step S11. As the home location register of the mobile communication system receives the service request message transmitted from the calling mobile communication terminal, the home location register performs an authentication process including whether the calling mobile terminal is a normal subscriber and whether or not it has a service right. The encryption related information on the traffic between the terminal and the mobile communication system is transmitted to the calling mobile communication terminal (S13).

Subsequently, the originating mobile communication terminal and the mobile communication system perform a radio access bearer (RAB) setting step, which is a process of setting a path for user traffic (S15).

In step S15, a traffic radio bearer is set between the originating mobile communication terminal and the radio network controller, and a RAB is established between the originating mobile communication terminal and the core network by setting up a bearer between the radio network controller and the core network. do.

Subsequently, the destination exchange transmits paging to the destination mobile communication terminal in response to the incoming request message transmitted from the originating exchange (S17).

Then, when the destination mobile communication terminal receives the paging transmitted from the destination exchange, the SRB performs a SRB setup process to transmit a paging response to the mobile communication system (RRC connection setup process) (S19).

As the terminating mobile communication terminal transmits a paging response message to the mobile communication system through the SRB set in step S19, the mobile communication system performs an authentication procedure for the terminating mobile communication terminal (S21). Here, since the procedure of authenticating the incoming mobile communication terminal is the same as the authentication procedure of step S13, a detailed description thereof will be omitted.

Subsequently, a procedure of setting up a traffic radio bearer of the called mobile communication terminal is performed, which is the same as setting up a radio access bearer mentioned in step S15 (S23).

A ring is sent to the called mobile communication terminal, and a call is performed with the call open between the calling mobile terminal and the called mobile communication terminal according to a user's selection (Alerting and Connect process) (S25), (Data Flow). (S27).

Thereafter, the call connection between the calling mobile communication terminal and the called mobile communication terminal is released (S29).

As mentioned above, a call processing procedure is performed, and a network operator is studying a method for shortening the time required to perform call processing to provide a faster call processing service to a mobile terminal user.

The asynchronous mobile communication system 20 is a radio network controller (RNC) 210 for controlling Node B 205 and Node B 205 as a base station for radio section communication with the mobile communication terminal 100, and a wireless network. Asynchronous exchange (asynchronous MSC) 220, asynchronous exchange 220 and the No.7 common signal network 230 is connected to the controller 210 and performs a call exchange for providing a service to the mobile communication terminal 100 Short Message Service Center (SMSC) 240, Intelligent Network Controller (SCP) 250 and Home Location Register (HLR) 260, Wireless Network Controller 210 and General Packet Radio Service (GPRS) network 280 connected via Is connected between the serving GPRS support node (SGSN) 270, the SGSN (270) and the General Packet Radio Service (GPRS) network to maintain a location track of the mobile communication terminal 100 and perform access control and security functions. A gateway GPRS support node (GGSN) 290 connected to the Internet 40 and connected to the Internet 40 to support interworking with external packets. .

Although not shown, the asynchronous mobile communication system 20 further includes a core network (CN) that is connected to the asynchronous exchange 220 and provides a core function for a mobile communication service.

The home location register 260 may be implemented as a dual stack home location register. The home location register 260 may store and manage subscriber information, additional service usage, and the like, and provide subscriber information at the request of the exchange 220.

When the radio network controller 210 receives a radio access bearer (RAB) allocation request message transmitted from a core network (not shown), the radio network controller 210 simultaneously transmits the message to the node B 205 and the mobile communication terminal 100. The node B 205 transmits a radio link reconfiguration message to the node B 205 and a radio bearer setup message to the mobile communication terminal 100.

Accordingly, the traffic connection setting process between the mobile communication terminal 100, the Node B 205 and the wireless network controller 210 can be simultaneously performed, thereby reducing the call connection time.

First, when the radio network controller 210 receives a radio access bearer (RAB) assignment request message transmitted from a core network (not shown) (RAB Assignment Request) (S101), the node A radio link change message is transmitted to the B 205 (Radio Link Reconfiguration) (S103).

In addition, the radio network controller 210 transmits a radio bearer setup message to the mobile communication terminal 100 (Radio Bearer Setup) (S105).

Step S103 and step S105 are performed at the same time, when the wireless network controller 210 receives the RAB allocation request message transmitted from the core network, and simultaneously transmits the message to the node B 205 and the wireless network controller 210.

Subsequently, the radio network controller 210 receives a radio link change waiting message transmitted from the node B 205 in response to the radio link change message of step S103 (Radio Link Reconfiguration Ready) (S107).

Steps S103 to S107 are performed by the radio network controller 210 to the node B 205 including the bearer type, power value, channel code, etc. to establish a traffic bearer between the node B 205 and the mobile communication terminal 100.

Thereafter, a data transmission bearer is set up between the Node B 205, the radio network controller 210, and the core network (Data Transport Bearer Setup) (S109).

The radio network controller 210 transmits a radio link change command message to the node B 205 through a wired / wireless traffic path between the mobile communication terminal 100 and the radio network controller 210 established through the previous procedure ( Radio Link Reconfiguration Commit (S111).

Thereafter, when the radio network controller 210 receives the radio bearer setup complete report message transmitted from the mobile communication terminal 100 (Radio Bearer Setup Complete) (S113), the radio network controller 210 transmits a RAB assignment response message to the core network (S115). .

As a result, as soon as the radio network controller 210 receives the RAB allocation request message in step S101, the radio network controller 210 transmits a radio bearer setup message to the mobile communication terminal 100, thereby transmitting the mobile communication terminal 100, the node B 205, and the radio. The traffic connection setting process between the network controllers 210 may be simultaneously performed.
