The present invention relates to a method and system for providing a CDMA 2000 1X unauthorized radio access service. More specifically, it connects a CDMA 2000 mobile communication network with a telephone, the Internet, and a wireless device in a building or home using an unlicensed unlicensed frequency band such as Bluetooth or 802.11, and integrates voice and packet services to provide a mobile communication service. CDMA 2000 1X Unlicensed Mobile Access (UMA) service providing method and system.

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.

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

A CDMA 2000 1X Unlicensed Wireless Access (UMA) service system according to a preferred embodiment of the present invention (UMA) service system (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 referred to as "CUC") 128, Mobile Switching Center (MSC: `` MSC '') 130 and a Packet Data Serving Node (PDSN) 140 (hereinafter referred to as PDSN).

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.

In the present invention, an interface between the MS 110 and the CUC 128 is defined as an up interface in the following process.

The standard AP 122 serves as a base station for the CDMA 2000 1X UMA service, and the broadband IP network 124 is a wired network and WiMAX (Asymmetric Digital Subscriber Line (ADSL) / Very High-data Rate Digital Subscriber Line (VDSL). 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 includes a separate Network Identification (NID), System Identification (SID), and Pseudo-Noise Offset (PN) as an integrated form of the Base Station Controller (BSC) / Base Transceiver Station (BTS) of the 1X system. It is connected to the MSC 130 and PDSN 140 of the existing 1X system through the standard interfaces A1 / A2 and A10 / A11.

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 accordance with a preferred embodiment of the present invention, signaling between the MS 110 and the CUC 128 at the up interface, user traffic framework, and thus the protocol architecture are defined.

In addition, in the present invention, the CDMA 2000 1X UMA service through the up interface is divided into a voice call and a packet call, and a protocol structure for each voice call and the packet call is divided into a control plane and a user plane.

2 is a diagram illustrating a control plane protocol structure for voice service in a CDMA 2000 1X UMA system according to a preferred embodiment of the present invention.

MS 110 and CUC 128 are IP connected via standard AP 122 and broadband IP network 124, and voice data is encrypted by Internet Protocol Security protocol (IPSec) for protection. IPSec is a communication protocol that realizes safe communication on the Internet, which is vulnerable to security. It is a communication protocol that prevents data eavesdropping by establishing a virtual dedicated line that can be used like a dedicated line on the Internet. IPsec may be mounted on the MS 110, and only a specific client and server may exchange data via IPsec through the Internet. IPSec provides security services such as an authentication header that allows authentication of the data sender and an encapsulating security payload (ESP) that supports the sender's authentication and data encryption.

In addition, it may further have a Remote IP between the MS 110 and the CUC 128, using TCP to deliver signaling messages without error.

In addition, an application layer between the MS 110 and the CUC 128 is defined as a Up-CS (Circuit Service), and the CUC 128 and the MSC 130 are connected through an existing standard A1 interface. .

3 is a diagram illustrating a user plane protocol structure for voice service in a CDMA 2000 1X UMA system according to a preferred embodiment of the present invention.

The MS 110 and the CUC 128 perform data transmission and reception through an IP connection and, in order to efficiently transmit voice data, such as Voice Over Internet Protocol (VoIP), Real-time Transport Protocol / User Datagram Protocol). In addition, although voice data does not necessarily need to use a CDMA 2000 vocoder, the present invention considers the CDMA 2000 vocoder in consideration of the fact that the MS 110 includes existing CDMA 2000 functions. For example, the CUC 128 converts the EVRC data of the MS 110 into a PCM and forwards it to the MSC 130. The CUC 128 and the MSC 130 are connected through an existing standard A11 interface.

4 is a diagram illustrating a control plane protocol structure for data service in a CDMA 2000 1X UMA system according to a preferred embodiment of the present invention, and FIG. 5 is a diagram illustrating data service in a CDMA 2000 1X UMA system according to a preferred embodiment of the present invention. A diagram showing a user plane protocol structure for the above.

In accordance with a preferred embodiment of the present invention, the CUC 128 is connected via the existing A11 interface with the PDSN 140 of the 1X system to provide CDMA 2000 1X UMA packet services. The MS 110 is assigned an IP through the PDSN 140 and the PPP, and data encoded in the PPP is transmitted and received between the MS 110 and the CUC 128 through UDP. CUC 128 forwards this data to PDSN 140 via a standard A10 interface.

6 is a flowchart illustrating a method for providing a service discovery and registration service in a CDMA 2000 1X UMA system according to an embodiment of the present invention.

In the present invention, through CDMA 2000 1X UMA service, in order to receive CDMA 2000 1X service, service discovery and registration and location update service must be performed in parallel. The service discovery and registration service is performed by the MS 110 entering the CDMA 2000 1X UMA service area and enters a building or area where a user with a terminal supporting the CDMA 2000 1X UMA service can access unlicensed radio access. In one case, the MS 110 needs to find out whether the CDMA 2000 1X UMA service is available and the CUC 128 to provide the actual CDMA 2000 1X UMA service. In addition, the IP address or server name of the URS 126 must be registered in advance in the MS 110, and the MS 110 must provide an interface for setting the URS 126.

According to a preferred embodiment of the present invention, when the MS 110 enters the CDMA 2000 1X UMA service area, the MS 110 queries the CUC 128 for the availability of the CDMA 2000 1X UMA service (Service Request Message). ) Is transmitted to the URS 126 (S610). The service request message includes an ID value of the standard AP 122 to which the MS 110 is currently connected. This ID value is an Information Element (IE) required to find a serviceable CUC 128. In addition, the IE format of the ID is determined according to the type of the standard AP 122.

When the URS 126 can accept the CDMA 2000 1X UMA service request of the MS 110 based on the location information received from the MS 110, the URS 126 sends a service acceptance message of the IP address of the CUC 128. It transmits to the MS 110 through (S620).

The MS 110 transmits a login request message to the CUC 128 provided by the URS 126 and requests the CDMA 2000 1X UMA service to be provided (S630). The MS 110 recognizes the CUC 128 that transmitted the login request message as one base station of the CDMA 2000 1X having NID, SID, and PN offsets based on the CDMA 2000 1X. In addition, if the location request information of the MS 110 is not included in the login request message, the CUC 128 does not perform periodic location information update. That is, the period of location information update is 1 second, and if interval time = 0, location information update is not performed.

CUC 128 performs basic authentication and location registration of MS 110 through MSC 130. This process will be described in detail with reference to FIG. 7.

If the authentication and location registration is successful and can accept the login request of the MS (110), the login acceptance message (Login Accept Message) is sent to the MS (110) to inform the login acceptance (S640). If authentication and location registration fail, a login reject message is sent to the MS 110. If it fails, the MS 110 to follow up according to the cause. Here, the login reject message includes information of the other CUC 128 so that the MS 110 can be provided with the CDMA 2000 1X UMA service through the other CUC 128.

The exchange of messages related to service discovery and registration is done via TCP communication between the MS 110 and the URS (S126) or the CUC 128. The URS 126 and the MS 110 use TCP port number = #n as the designated port, and the CUC 128 and the MS 110 also specify the TCP port number = #m for UP-CS. Used as a port.

7 is a flowchart illustrating a method of providing a location registration and update service in a CDMA 2000 1X UMA system according to a preferred embodiment of the present invention.

Location registration and update of the MS 110 according to a preferred embodiment of the present invention is performed periodically after a certain time while the MS 110 stays in the CDMA 2000 1X UMA service area. The MS 110 supporting the CDMA 2000 1X UMA service receives a location information update request when registering a service with the CUC 128. That is, the MS 110 performs location information update based on the requested period while staying in the CDMA 2000 1X UMA service area.

According to a preferred embodiment of the present invention, when the location information timer expires, the MS 110 transmits a registration request message to the CUC 128 (S710).

Upon receiving the authentication request message from the MS 110, the CUC 128 transmits a location update request message to the MSC 130 (S720).

Upon receiving the location information update request message from the CUC 128, the MSC 130 not only updates the location of the MS 110, but also performs basic authentication of the MS 110 as necessary, thereby accepting the location information update of the MS 110. Or transmits a rejection message (Location Update Accept / Rejection Message) to the CUC (128) (S730).
