The present invention relates to a method and a system for enabling / disabling a CDMA service of a CDMA 2000 1X unauthorized radio access service. More specifically, MS supports CDMA 2000 1X Unlicensed Mobile Access (UMA) service, which integrates voice and packet services over existing CDMA 2000 1X mobile networks in a home or building using unlicensed frequencies. And a method for setting up / releasing voice and packet calls among CDMA 2000 services through a network device.

The mobile communication system has been developed through a first generation analog AMPS (Advanced Mobile Phone System) method, a second generation cellular (Cellular) / personal communication service (PCS) method, and recently, a third generation high speed data. International Mobile Telecommunication-2000 (IMT-2000) has been developed.

The IMT-2000 service may be classified into a code division multiple access (CDMA) 2000 1X service and a CDMA 2000 1x EV-DO service. The CDMA 2000 1X service uses the IS-95C network, which has evolved from the existing IS-95A and IS-95B networks. Internet-enabled service.

Accordingly, the CDMA 2000 1X service enables the improvement of existing voice and WAP (Wireless Application Protocol) service quality as well as the provision of various multimedia services (AOD, VOD, etc.).

Meanwhile, the IMT-2000 system for the multimedia mobile communication service defined the standard of the synchronous IMT-2000 system in the 3rd Generation Partnership Projects (3GPP2), an international standardization organization. The method based on the company's high data rate (HDR) was named "CDMA 2000 1x EV-DO (Evolution Data Optimized)" and was confirmed as an international standard. CDMA 2000 1x EV-DO (hereinafter, referred to as '1x EV-DO') is a communication standard of CDMA 2000 1X (hereinafter, referred to as '1X'). to be.

1X provides a unidirectional high speed data service with a transmission rate of up to 307.2 Kbps in the form of a mixture of a circuit network and a packet network. In addition, 1X also offers increased system density, which reduces equipment footprint and enables step-by-step investments in the wireless data market. Applications of 1X include support for multimedia services such as real-time video service, video / music, video clip, video chat, video e-mail, and various wireless data service fields. 1X was launched in October 2000 by SK Telecom.

In addition, 1x EV-DO is a wireless access technology standard optimized for high-speed and high-capacity data transmission, providing bidirectional high-speed data service at a transmission speed of up to 2.4 Mbps for packet networks only. The 1x EV-DO is a step forward from 1X and uses the advantages of time division multiple (TDM) over CDMA technology to transfer data. The maximum transfer rate is 1,457 Mbps, which is 16 times higher than 1X, and the capacity is five times higher. This capability enables the provision of multimedia content in areas such as wireless Internet access, real-time traffic information, wireless live broadcasting, television, movies, music videos, internet games, and M-commerce. Current 1x EV-DO systems are used interchangeably with existing 1X systems.

As described above, the current CDMA mobile communication system has a number of Km within the cell managed by the base station itself, and provides wireless voice and packet services for mobile stations such as mobile communication terminals in the corresponding area.

Meanwhile, there is a separate service for providing a wireless mobile communication service in a building or a home through unlicensed radio such as wireless LAN, 802.11, or Bluetooth. Such a service is called an Unlicensed Mobile Access (UMA) service.

Unlicensed wireless access service is a wireless service access technology that connects a mobile communication terminal, a radio, a portable electronic device, a computer, etc. using a frequency band that does not require a license. It also connects mobile phones such as home telephones, the Internet, wireless devices, and GSM (Global System for Mobile communication), GPRS (General Packet Radio Service) while using unlicensed frequency bands such as WLAN, 802.11, or WLAN. It is a wireless access technology that integrates voice, data, and IMS / SIP (IP Multimedia Subsystem / Session Initiation Protocol) services.

The UMAC (Unlicensed Mobile Access Consortium) consortium is leading the standardization of wireless access technology and is standardized as part of 3GPP specification TS 43.318.

The unlicensed wireless access service using the unlicensed frequency uses an IP network through a separate network from the CDMA mobile communication network, and thus there is a technical problem that cannot provide compatibility with the CDMA mobile communication network.

Therefore, in the present invention, to solve this problem, while using an unlicensed frequency band such as Bluetooth or 802.11, wirelessly connects the CDMA mobile communication method with a home telephone, the Internet, a wireless device, and integrates voice and packet services. We will define an access technology and propose a method for setting and releasing voice and packet calls among CDMA services using them.

1 is a diagram schematically showing a CDMA 2000 1X UMA service providing system according to a preferred embodiment of the present invention.

CDMA 2000 1X Unlicensed Wireless Access (UMA: Unlicensed Mobile Access (UMA)) service providing system according to a preferred embodiment of the present invention is a mobile terminal (MS: Mobile Station, hereinafter referred to as "MS") 110 ), CDMA 2000 UMA network (CUN: CDMA 2000 UMA Network, hereinafter referred to as 'CUN') 120, Standard AP (Standard Access Point) 122, Broadband IP Network (124), UMA registration Server (URS: UMA Registration Server, hereinafter referred to as "URS") 126, CDMA 2000 UMA Controller (CUC: CDMA 2000 UMA Controller, hereinafter called "CUC") 128, Mobile Switching Station (MSC: Mobile Switching) Center, hereinafter referred to as 'MSC' 130, and a packet data serving node (PDSN: hereinafter referred to as 'PDSN') 140.

The MS 110 is a terminal that receives voice and data services by connecting to a mobile communication network of a 1X system or a CUN 120 of a CDMA 2000 1X UMA system, and periodically connects a system to which it is connected, for example, a 1X system or a UMA system. If a call is made from the system being accessed and the call is made, the CDMA 2000 1X UMA service is processed in response to the call.

CUN 120 is configured to include standard AP 122, broadband IP network 124, URS 126, and CUC 128, etc. to provide CDMA 2000 1X UMA service to MS 110, and MS 110 Is connected via an IP connection with the CUC 128 via a standard AP 122 and a broadband IP network 124.

The standard AP 122 serves as a base station of the CDMA 2000 1X UMA service system, and the broadband IP network 124 is a wired network and WiMAX of Asymmetric Digital Subscriber Line (ADSL) / Very High-data Rate Digital Subscriber Line (VDSL). It may be a wireless network such as (WiMAX) or WiBro.

The URS 126 performs authentication and location registration when the MS 110 accesses the CDMA 2000 1X UMA system. When the MS 110 succeeds in authentication, the URS 126 transmits the IP address of the CUC 128 to the MS 110. Performs the function of allowing the CUC 128 to connect.

The CUC 128 is an integrated form of the Base Station Controller (BSC) / Base Transceiver Station (BTS) of the 1X system, including separate network identification (NID), system identification (SID), and pseudo-noise offset (PN offset). It is configured, and is connected to the MSC (130) and PDSN (140) of the existing 1X system through the standard interface A1 / A2, A10 / A11 interface (Interface).

The MSC 130 is connected to the CUN 120 to provide a CDMA 2000 1X service to the MS 110, and performs an interworking function with an exchange of a public telephone network. In addition, the MSC 130 performs basic and additional service processing, incoming and outgoing call processing of subscribers, location registration and handoff procedures, and interworking with other networks. The MSC 130 of the IS-95 A / B / C system includes an Access Switching Subsystem (ASS) that performs distributed call processing, an Interconnection Network Subsystem (INS) that performs centralized call processing, operation and maintenance. Subsystems include a Central Control Subsystem (CCS) in charge of the centralization function, and a Location Registration Subsystem (LRS) that performs storage and management of information on mobile subscribers.

The PDSN 140 is connected to the CUN 120 to transmit packet data using a Point to Point Tunneling Protocol (PPP) and a Transmission Control Protocol (TCP) / Internet Protocol (IP) protocol between Data Core Networks (DCNs). Provide service. The PDSN 140 differentiates and provides a packet data service for each subscriber by dividing into a simple IP, a basic mobile IP, and an enhanced mobile IP.

In the following process of the present invention will be described in detail a method for setting and clearing voice and packet calls in the CDMA 2000 1X UMA service system.

According to a preferred embodiment of the present invention, when the MS 110 supporting the CDMA 2000 1X UMA service receives or makes a voice call, the CDMA 2000 1X UMA service is activated through a service discovery and registration operation. If possible, a process of setting up a voice call of the CDMA 2000 1X UMA service is performed. In addition, the MS 110 sets up and releases a packet call to receive packet service through the PDSN 140.

 2 is a flowchart illustrating a method of establishing a voice call by an MS in a CDMA 2000 1X UMA service according to an embodiment of the present invention.

According to a preferred embodiment of the present invention, if a user attempts to make a voice call to perform a voice call while receiving a CDMA 2000 1X UMA service using the MS 110, the MS 110 may request a CDMA 2000 1X UMA service. In order to set up a CDMA 2000 1X voice call, a CUC origination message is transmitted to the currently connected CUC 128 (S202).

The CUC 128 transmits a CUC Reverse Acknowledgment Message to the MS 110 in order to receive it from the MS 110 and proceed with the voice call setup (S204), and simultaneously to the MSC 130. A service request message (CM Service Request Message) is transmitted (S206), an assignment request message (Assignment Request Message) is received from the MSC 130 (S208), and user access authentication is performed. Here, the MS 110 receiving the CUC reverse acknowledgment message checks whether the message transmitted to the CUC 128 is normally received through the same field value and the message sequence of the finally transmitted message.

When the CUC 128 receives a voice call setup permission from the MSC 130, a CUC channel assignment message including resource information for providing a voice call service, an IP address, and UDP port for RTP stream information for an RTP stream is provided. The CUC channel assignment message is transmitted to the MS 110 (S210).

Here, the CUC channel assignment message includes the IP address and UDP port of the CUC 128 to receive reverse VoIP or packet traffic, and the channel coding and voice samples for VoIP through the channel assignment message. Voice Sample Size information is provided. The CUC 128 maintains the PCM connection with the existing vocoder with the MSC 130, and the CUC 128 and the MS 110 establish a VoIP traffic path. This is an IE (Information Element) set only for voice calls.

Upon receiving the CUC channel assignment message, the MS 110 transmits a null RTP stream to the UDP port indicated in the message (S212), and the CUC 128 terminal to the UDP port designated in the CUC channel assignment message. Check if this transmitted null RTP stream is received.

The MS 110 transmits a CUC Channel Assignment Acknowledgment Message, which includes its own IP address and UDP port information for the RTP stream, to the CUC 128 (S214).

After confirming that the reception of the CUC channel assignment grant message is successful, the CUC 128 transmits a null RTP stream with UDP port information for the IP address and RTP stream of the MS 110 carried in the CUC channel assignment grant message (S216). . When the transmission of the null RTP stream is normally performed, the CUC 128 sends a CUC Service Connect Message indicating that the forward / reverse RTP stream for VoIP is normally connected. (S218).

When the MS 110 receives the CUC service connection message from the CUC 128 and confirms the normal connection, the MS 110 starts transmitting to the CUC 128 through the UDP port to which the reverse RTP stream is allocated. In addition, the CUC Forward Acknowledgment Message (CUC Forward Acknowledgment Message) is transmitted to the CUC (128) to inform the reception of the connection of the service.

The CUC 128 transmits an assignment complete message to the MSC 130 (S222), indicating that the setup between the MS 110 and the CUC 128 is successful.

The CUC 128 begins to transmit the Forward RTP Stream with the MSC 130 to the MS 110 through the standard AP 122, and the Reverse RTP Stream is converted into the PCM to convert the MSC. In step S224, the process of transmitting the PCM transmission operation is actually started.

3 is a flowchart illustrating a voice call setup method by a CUC in a CDMA 2000 1X UMA service according to an embodiment of the present invention.

According to a preferred embodiment of the present invention, if a paging request message (Paging Request Message) is transmitted from the MSC 130 to the CUC 128, the incoming call process of the voice call is started (S302).

Upon receiving the voice call incoming request message from the MSC 130, the CUC 128 transmits a CUC Paging Request Message to the corresponding MS 110 (S304).

Upon receiving this, the MS 110 transmits a CUC Paging Response Message to the CUC 128 (S306).
