Description

Apparatus of processing signal in ALL-IP network and registration method of terminal in IPMM domain using the same}

The invention ^{3GPP (3 rd Generation Partnership Projects)} UMTS (Universal Mobile Telecommunication Service), 3GPP2 IMT-2000 (International Mobile Telecommunication) next-generation mobile communication network based integrated Internet Protocol (ALL-IP), such as base station controllers in the network (BSC: The present invention relates to a signal processing device of a base station controller, a terminal registration method to an Internet Protocol Multimedia (IPMM) domain using the same, and a computer-readable recording medium recording a program for realizing the method. .

At present, 3GPP and 3GPP2, two organizations of the International Standardization Conference, have discussed the issue of an integrated IP (All-IP) network, in which the entire network of the IMT-2000 system is based on Internet Protocol (IP). Future standardization standards are expected to include specifications for implementing All-IP networks.

All-IP network is a network using IP for all transmissions from terminal to core network and is expected to be evolved from existing network for compatibility with current mobile communication network.

3GPP defines the All-IP core network as "Release 2000 core that uses IP for the transport of all user data and signaling", and 3GPP2 "produces IP for user data and signaling between all network entities, including the terminal." IP-based network using "."

The all-IP network has an open structure in the form of a data network, which enables effective introduction of various services to be deployed in the future, especially IP-based services, and enables integrated and low-cost maintenance using IP. In addition, by using IP, it is possible to provide a flexible service regardless of access means (PSTN, LAN, HIPERLAN, Cable, Wireless, etc.), and has the advantage of efficiently constructing a multimedia service.

Currently, packet service is defined as 384Kbps in IS-2000, and standardization of "Release B" is being performed in 3GPP2 TSG-C for high speed packet service.

"Release B" shows a standard model for packet service of 2Mbps or more as shown in FIG. ALL-IP Adhoc also proposes a standard model of the ALL-IP network based on RN-4286 presented in 3GPP2, and standardization is currently in progress.

1 is a configuration example of a conventional network, ^{3GPP2 (3 rd Generation Partnership Projects-} 2) Fig.

Radio Access Network (RAN) 2 is composed of a Base Station Controller (BSC), Packet Control Function (PCF) and Base Station Transceiver Subsystem (BTS). Mobility management and authentication of a mobile station (MS) 1 is provided through a Visitor Location Register (VLR) 3 and a Home Location Register (HLR) 4.

When the basic authentication of the data call is completed, the radio access network (RAN) 2 establishes a virtual connection for the packet data service node (PDSN) 6 and the Generic Routing Encapsulation (GRE) protocol.

The Packet Data Service Node (PDSN) 6 establishes a Point-to-Point Protocol (PPP) connection with the MS 1 and establishes a Remote Authentication Dial In User (RADIUS) service. Service) Transfer subscriber authentication and billing information through server.

In providing the mobile IP service, the packet data service node (PDSN) 6 performs an external agent (FA) function, and the home agent (HA) 5 existing in the home network of the terminal IP address is positioned for the mobile IP. It performs functions such as information management and tunnel setup.

As such, the conventional packet control function unit (PCF) is an interworking system of a radio access network (RAN) 2 for interworking with a packet network, and the packet data service node (PDSN) 6 is a radio access network (RAN). It functions as an access node for connecting the data subscriber connected through (2) to the packet network, so that the radio access network (RAN) 2 and the packet network are completely separated.

However, in the future, 3GPP2 network or ALL-IP network is evolving the whole into one IP network, and existing base station controller (BSC), packet control function (PCF) and packet data service node (PDSN) It is viewed as a system called a wireless access gateway (WAG). Accordingly, access nodes of data subscribers are increasingly being moved to the lower level of the network as they are integrated into a single wireless access gateway (WAG).

In the IS-2000 system, initial registration of a terminal (mobile station (MS)) is performed by receiving a broadcast message transmitted from the system and registering the terminal in a subscriber information database (DB) of the network. In addition, in order to perform a packet service, the UE must first perform mobile Mobil IP registration. For this mobile IP registration, a wired bearer is allocated to an interface between a base station controller (BSC) and a packet data service node (PDSN), and a wireless traffic channel is allocated in a wireless section to register a mobile IP in this allocated channel. The message must be sent (see FIGS. 1 and 2).

The standard model in progress in All IP Adhoc is ANSI-41 (TIA) for IP Multi-Media (IPMM) Domain for Packet and existing Circuit Service for Core Network (CN). / EIA-41) Defines a domain. As the basic protocol of IPMM, protocols such as Mobile IP, IOS, and ANSI-41 are used.

In order for a terminal (mobile station (MS)) to register in an IPMM domain, a mobile IP registration process is required. In the existing system, the existing system allocates a wire bearer between a traffic channel and a wired station in a wireless section, and then transmits messages required for registration through this channel. However, in the case of the currently defined All-IP network, the procedure for allocating a radio segment channel assignment and a wire bearer necessary for the UE to register in the IPMM domain is performed in the existing IS-2000 channel of the radio segment. This is different from the setup procedure.

Therefore, in the process of registering the terminal in the IPMM domain of the All-IP network, a new registration procedure considering the existing IS-2000 channel setup process is required.

The present invention has been proposed in order to meet the above-described requirements. In the next generation mobile communication network-based Integrated Internet Protocol (ALL-IP) network, a base station controller (BSC) signal processing device and terminal registration to the IPMM domain using the same It is an object of the present invention to provide a computer-readable recording medium storing a method and a program for realizing the method.

Currently defined All-IP network structure defines ANSI-41 domain for existing service and IP Multimedia (IP Multimedia) domain for new packet service. In this network structure, in order for a terminal (mobile station) to perform a packet service, a procedure for registering a terminal in an IPMM domain should be performed first. And this registration procedure is defined in the All-IP document (see Figure 5 below).

The registration procedure of FIG. 5 defines a new message and procedure different from the existing IS-2000 used for radio channel assignment in a wireless network using the IS-2000 wireless protocol. However, the definition of these new messages and procedures means that in the network using the IS-2000 protocol, the terminal and the wireless network must perform different processing. However, this procedure can be defined using the procedures and messages of the existing IS-2000 protocol. In consideration of such a conventional method, there is an advantage that the protocol processing unit of the existing wireless network and the terminal can be used to the maximum. Therefore, the present invention proposes an IPMM domain registration procedure of a terminal considering an existing procedure rather than a new procedure in an existing protocol.

First, before the UE describes the registration procedure in the IPMM domain in the ALL-IP network, a signal processing apparatus of a base station controller (BSC) for supporting this will be described in more detail.

As shown in FIG. 4, a signal processing apparatus of a base station controller (BSC) may broadcast information about a network to a terminal at the time of initial registration of the terminal, and common signal processing unit to classify a signal received from the terminal. (41), an ANSI-41 signal processor (42) for transferring the TIA / EIA-41 (ANSI-41) signal transmitted through the common signal processor (41) to the ANSI-41 domain, and a common signal processor (41). IPMM signal processing unit 43 for transmitting the Internet Protocol Multimedia (IPMM) signal transmitted through the IPMM domain, and bearer signal processing unit 44 for setting the bearer between the other gateways in the ALL-IP network for transmitting user information do.

The signal processing device of the base station controller (BSC), in addition to the function for processing the existing ANSI-41 service for the IPMM domain of the All-IP network, the function for IPMM domain registration and wired / wireless section bearer allocation It must be done in addition.

The common signal processor 41 configures network information and other network information in a message for information transmission such as a broadcast message in order to transmit information about a network to the terminal during initial registration of the terminal.

The IPMM domain signal processor 43 processes the signal after that when the UE registers with the IPMM domain.

The ANSI-41 signal processor 42 performs the same function as the existing IS-2000-based signal processing, but uses other gateways (eg, access gateways, media, etc.) in the All-IP network for transmitting user information. The bearer signal processor 44 performs bearer setup between media gateways.

Among the functions of the base station controller BSC, the common signal processor 41 and the bearer signal processor 44 are subdivided in the functions performed by the conventional base station controller BSC. This function is not a newly defined block but a feature that adds a procedure considering the IPMM domain to an existing message and processing procedure. The BSC structure has an advantage of effectively providing the processing of the IPMM domain of the All-IP network while maximizing the structure and function of the base station controller (BSC) used in the existing network.

Now, the UE registration procedure from the ALL-IP network to the IPMM domain will be described in more detail.

First, referring to FIG. 5, the registration procedure of the terminal to the IPMM domain presented in the All-IP standardization is presented, and then a modified procedure considering the procedure in the existing IS-2000 network is presented.

The existing operation procedure of the terminal to the IPMM domain proposed in All-IP standardization is as follows.

First, in operation 501, a radio network transmits information through a broadcast channel to support an ANSI-41 network, an IPMM network, or two networks. Then, the terminal (mobile station MS) requests registration to the network based on the received message (502). In this case, it is assumed that the registration in the IPMM network.

Thereafter, the base station controller BSC of the wireless network transmits a registration message sent from the terminal (mobile station MS) to the mobility manager (MM) (503). The mobility manager MM then sends 504 the received message to a local authorization / authentication / billing (Local AAA) server for authentication. In this case, it is assumed that the terminal (mobile station) is in a network other than the registered network. If there is a terminal in the registered network, a message is directly sent to a home authorization / authentication / billing (Home AAA) server.

Subsequently, the Local AAA server sends this message to the Home AAA server (505). Actual authentication takes place at Home AAA.

Then, the home authorization / authentication / charging (Home AAA) server performs authentication and transmits the result to the local authorization / authentication / charging (Local AAA) server (506). Thereafter, the Local AAA server sends the received result to the Mobility Manager (MM) (507). The mobility manager MM then transmits the received results to the base station controller BSC (508).

Next, the base station controller BSC informs that the terminal (mobile station MS) has been registered with the access gateway (AGW) (509). Then, the access gateway device AGW registers the location information with the position server for the location information service (510), and the location server transmits the response to the access gateway device (AGW) (511).

Thereafter, the access gateway device AGW transmits the received result to the base station controller BSC (512), and the base station controller BSC sends a response to the registration requested by the terminal (mobile station MS) to the logical connection ID. The data is transmitted together with the (Logical Connection ID) (513).

Subsequently, the terminal (mobile station (MS)) transmits a physical connection establishment request of the basic service option to the base station controller (BSC) based on the received result (514), and the base station controller (BSC) sends the terminal (mobile station (mobile station (MS)) MS)) is sent to the access gateway (AGW) (515).

Thereafter, the access gateway (AGW) establishes a physical connection and sends a response to the base station controller (BSC) (516). Then, the base station controller BSC transmits a response to the physical connection establishment request to the terminal (mobile station MS) (517). In addition, the base station controller (BSC) is an access gateway device (AGW) terminal (mobile station (MS)) has completed the traffic channel allocation (Accounting Start Message) including the accounting information (Accounting) information for charging Send 518. Accounting information is transmitted to an authorization / authentication / billing (AAA) server.

Next, the access gateway (AGW) transmits a response message to the base station controller (BSC) (519).

Thereafter, after the wired / wireless traffic channel is established between the terminal (mobile station MS), the base station controller (BSC), and the access gateway device (AGW), the access gateway device (AGW) advertises for the terminal (mobile station (MS)). (520) prepare to send an Advertisting message. This message may include the SCM address for the emergency call, the DNS address of the network, and the DHCP address.

Next, the access gateway device AGW transmits a Mobile Internet Protocol (MIP) Agent Advertisement message to the terminal MS, and receives the Agent Advertisement message 521. The mobile station MS sends a MIP registration message to the access gateway device AGW (522). Then, the access gateway (AGW) requests the authentication request to the local authorization / authentication / billing (Local AAA) server for the registration message requested by the terminal (mobile station (MS)) (523), local authorization / authentication / billing ( Local AAA) server sends a message to the Home Authorization / Authentication / Billing (Home AAA) server (524).

Subsequently, the Home AAA server updates the Dynamic Subscriber Information (DSI) database (the address update of the access gateway device) (525), and the DSI database grants the home response an update response. It transmits to the / authentication / billing (Home AAA) server (526). Then, the Home AAA server transmits a response to the Local AAA server 527.

Meanwhile, the terminal (mobile station MS) periodically transmits the MIP registration request message to the access gateway device AGW until it receives a response message for the MIP registration request (528).

On the other hand, if the Local AAA server sends a HA request message to the home agent (HA) (529), the home agent (HA) processes the registration message and then processes the local authorization / authentication / billing ( Local AAA) transmits a response to the server (530). Thereafter, the local AAA server transmits the final result to the access gateway (AGW) (531), and the access gateway device (AGW) transmits the result of the MIP registration message to the terminal (mobile station (MS). (532).

After transmitting the response to the registration to the terminal (mobile station (MS)), the access gateway (AGW) transmits the Accounting_Request Start message to the local authorization / authentication / billing (Local AAA) server for billing (533). Then, the local authorization / authentication / billing (Local AAA) server transmits a message for the received charging to the home authorization / authentication / charging (Home AAA) server (when Home AAA operates on the final charging) (534 )

Subsequently, when the home authorization / authentication / billing server receives the message and transmits a response to the local authorization / authentication / charging (Local AAA) after processing (535), the local authorization / authentication / charging (Local AAA) server 5 transmits the response to the access gateway (AGW) (536).

6 is a flowchart illustrating a method for registering a terminal to an Internet Protocol Multimedia (IPMM) domain according to the present invention.

When performing step 514 of FIG. 5, the terminal (mobile station) transmits a newly defined Level 2 Physical Bearer Setup message to the base station controller (BSC) for wireless interval channel allocation. In order to allocate the interval channel, the MSC transmits a message related to radio segment allocation to a base station controller BSC which manages radio channel related information, and the base station controller BSC transmits a message regarding radio channel allocation to a terminal (mobile station (mobile station (MS)). MS)) to assign a radio channel (see steps d, e, and f of FIG. 2).

Therefore, the steps "514" to "517" may be changed as shown in FIG. 6 in consideration of the procedure used in the IS-2000 protocol as follows. The newly proposed procedure is as follows. Other procedures are the same as those shown in FIG. 5 and will be omitted.

Specifically, after transmitting a response message for registration requested by the terminal to the terminal (mobile station (MS)), the base station controller (BSC) is a message for the assignment of the wired section bearer (bearer) to the access gateway (AGW) Transmit (614).

Thereafter, the access gateway device AGW transmits a response message to the base station controller BSC after allocating a wired bearer.

After the assignment of the wired bearer between the access gateway device AGW and the base station controller BSC is completed, the base station controller BSC is configured to allocate a traffic channel in a radio section. In step 616, a message for wireless interval channel allocation is transmitted.

Subsequently, after the allocation of the traffic channel in the wireless section is completed, the base station controller BSC transmits a response message indicating that the allocation of the bearer in the wired / wireless section for data transmission is completed to the access gateway (AGW) ( 617).

The method of the present invention as described above may be implemented as a program and stored in a computer-readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.).

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be apparent to those of ordinary knowledge.

As described above, the present invention relates to a specific system processing procedure for the RAN field in configuring an All-IP-based IMT-2000 system, which is a major standardization issue in 2000, in a standardization organization (3GPP, 3GPP2, ITU, etc.). It can be applied to the implementation and configuration of the RAN system of the All-IP network, and also by using the structure and functions of the existing BSC to the maximum, it is possible to flexibly cope with the effective function implementation and the implementation of additional functions later. have.
