Outgoing Procedure

4 is a flowchart illustrating a CDMA packet data call origination method according to the present invention.

First, when a mobile communication terminal attempts to make an origination to use a packet data service on a WLAN (origination) (S101), a home BTS (H-BTS) uses an access channel message transmission message based on the Abis protocol ( Abis-ACH Msg.Transfer (ORM) to notify the BSC (S103). Accordingly, the BSC requests access control service to the MSC (Complete L3 Info; CM Service Request) (S105), and the MSC performs authentication work on the corresponding mobile communication terminal (S107) and drives a timer to the BSC. Resource allocation request (Assignment Request) (S109).

In accordance with the MSC resource allocation request, the BSC sends a setup message to acquire a resource between the H-BTS and the BSC (Abis-BTS Setup) (S111), and if the resource is available, the H-BTS accesses the traffic to the BSC. The initialization message (Abis-Connect) is transmitted (S113). The BSC sends a response message (Abis-Connect Ack) to the traffic access initiation message to the H-BTS, so the H-BTS sends a response message to the setup message for a resource allocation request to the BTS (Abis-BTS Setup Ack). (S115, S117).

Next, the BSC transmits a basic channel omni frame message (Abis-IS-2000 FCH Fwd) including null data to the H-BTS (S119). In the conventional CDMA2000 mobile communication network, the BTS receiving the basic channel omni-directional frame message transmits the message to the mobile communication terminal, but the present invention does not need to transmit the message to the mobile communication terminal. Because, when the channel for transmitting data to the mobile communication terminal is a mobile communication network, the basic channel omni-directional frame message is used to drive the communication channel, but in the present invention, the mobile communication terminal and the H-BTS are connected through a wireless LAN. Therefore, it is not necessary to transmit such a message to the mobile communication terminal.

Receiving the basic channel omni-directional frame, the H-BTS transmits a basic channel reverse frame message (Abis-IS-2000 FCH Rvs) including idle data to the BSC to identify the traffic path (S121). Subsequently, the BSC transmits an Abis-PCH Msg Transfer including an Extended Channel Assignment Message (ECAM) to the H-BTS (S123). The BTS receiving the paging channel message in the conventional CDMA2000 mobile communication network transmits the message to the mobile communication terminal, but the present invention does not need to transmit the message to the mobile communication terminal. This is because the paging channel message is a message used in a general mobile communication network to determine the location of the mobile communication terminal. In the present invention, the moment the mobile communication terminal accesses the H-BTS, the H-BTS knows the location of the mobile communication terminal. Therefore, there is no need to transmit a paging channel message to the mobile communication terminal.

After exchanging forward and backward frame messages and exchanging paging channel information, the H-BTS transmits idle data to the BSC using a basic channel reverse frame message (Abis-IS-2000 FCH Rvs) (S125). Accordingly, the BSC recognizes that the mobile communication terminal is ready to use the call service, and has a basic channel omni-frame message including a BS Ack Order indicating that it is ready for packet data service. IS-2000 FCH Fwd) is transmitted (S127). This basic channel omni-frame message does not have to be transmitted from the H-BTS to the mobile communication terminal. This is because, as described above, when the mobile communication terminal and the H-BTS are connected through the WLAN, there is no need to transmit a separate message for driving the communication channel.

Subsequently, the H-BTS transmits idle data indicating that the mobile communication terminal is ready for packet data call service (Abis-IS-2000 FCH Rvs) (S129), and transmits a terminal response order message (MS Ack Order) to the BSC. (S131).

In this way, when the mobile communication terminal, the H-BTS and the BSC complete the preparation for the packet data service, the BSC requests to initiate connection establishment with the PCF (A9-Connect-A8) (S133), and thus the PCF. And PDSN perform a procedure for connection (A10 / A11 Connection Establishment Procedure) (S135). When the connection between the PCF and the PDSN is completed, the PCF establishes the A8 interface connection and reports that the connection is completed to the BSC (A9-Connetc-A8) (S137).

Next, the BSC sends a Service Connection Message (SCM) for configuring a packet data service using an Abis-IS-2000 FCH Fwd by using an elementary channel omni frame. In step S139, the H-BTS transmits a service access message (Service Connect) to the mobile communication terminal (S141). Accordingly, the mobile communication terminal starts to process the traffic according to the service configuration, and transmits a service connection completion message (Service Connect Completion) to the H-BTS using the basic channel reverse frame (S143).

Subsequently, the H-BTS includes a Service Connect Completion Message (SCCM) in the base channel reverse frame message (Abis-IS-2000 FCH Rvs) and transmits it to the BSC (S145), and the BSC allocates resources to the MSC. Report that the connection is established by reporting that the process is completed (Assignment Complete) (S147). Accordingly, a PPP connection establishment procedure is established between the mobile communication terminal and the PDSN (Establish PPP Connection) (S149), and a session for transmitting and receiving packet data is activated (Active Packet Data Session) (S151), and the actual packet data service is performed. You lose.

As described above, the call release procedure after the packet data service is initiated by the origination request of the mobile communication terminal connected to the WLAN and the portable Internet will be described.

Call Release Procedure

5 is a flowchart illustrating a method of releasing a CDMA packet data call according to the present invention, which shows a process of releasing a call at the request of a mobile communication terminal.

First, as the mobile communication terminal to release the call requests the call release to the H-BTS (Release Order) (S201), the H-BTS transmits a call release request message (Release Order) to the base channel reverse frame message (Abis-). It is included in the IS-2000 FCH Rvs) and transmitted to the BSC (S203). The BSC, which has received this, transmits a message (Clear Request) for starting the call release procedure to the MSC (S205).

Accordingly, the MSC instructs the BSC to release the associated dedicated resource (Clear Command) (S207), and the BSC transmits a basic channel omnidirectional frame message (Abis-IS-2000 FCH) including a call release indication message (Release Order). Fwd) is transmitted to the H-BTS (S209). In addition, the H-BTS receiving this transmits a response message (Release Order) to the mobile communication terminal (S211).

Next, the BSC requests to release the connection to the H-BTS (Abis-BTS Release) (S213) and the H-BTS sends a call release message (Abis-Remove) to the BSC (S215) and terminates the call. (S217). In addition, the BSC transmits a response signal Abis-Remove Ack to the call release message Abis-Remove received from the H-BTS (S219), and the H-BTS transmits a connection release request message (Abis-BTS) received from the BSC. Release a response message (Abis-BTS Release Ack) (S221).

Thereafter, the BSC instructs the PCF to release the resource by sending a message to switch the packet call to the Dormant state (A9-Release-A8) (S223), and the PCF issues a dorm indication instruction to the PDSN. Transfer to release the connection (A10 / A11 Accounting Procedure) (S225). When the connection between the PCF and the PDSN is released, the PCF reports to the BSC that the resource has been released (A9-Release-A8 Complete) (S227), and a message indicating that the BSC receiving the completion of the call release is completed to the MSC (Clear Complete). By transmitting the packet data call release procedure is completed.
