Abstract

PURPOSE: A method for managing an AT(Access Terminal) assignment call of a base station in an HDR(High Data Rate) system is provided to invest a work number corresponding to an intrinsic call of each AT by one-to-one when a plurality of ATs connect for an initial assignment, and manage the work numbers. CONSTITUTION: If a signal for requesting a UATI(Unicast Access Terminal Identifier) is received from an AT(S502), one work block capable of processing the call of the received signal is invested(S503). One record stored a queue is read, one work block is invested, and an intrinsic work number about RATI(Random Access Terminal Identifier) information transmitted from each AT is invested to the work block(S504). UATI information including information having the work number and the RATI is transmitted to an upper BSC(Base Station Controller) for requesting an assignment(S505). If the upper BSC successfully admits the request of the UATI assignment about the RATI, a base station transmits UATI information to the corresponding AT and performs the assignment(S506). If the UATI assignment process is ended, the base station returns the currently used work block as an original state to be used in an other AT(S507).

Description

{Management method for authentication call of terminal of base station in high data rate system}

The present invention relates to a base station of a high data rate (HDR) system, in which a plurality of terminals (AT) access one-to-one to each unique call for authentication when accessing the base station for initial authentication. The present invention relates to a method for managing a terminal authentication call of a base station in a high-speed data transmission system for assigning and managing a work number and using the same to communicate with a higher control station.

Recently, a new mobile communication system called IMT-2000 for data communication services has been proposed for providing data communication services such as the Internet to mobile communication users wirelessly. As an attempt of such a system, a new system for high data rate service (HDR) is introduced.

The HDR system has been proposed by Qualcomm as one of the third generation mobile communication systems (IMT-2000), and provides high-speed packet data services except real-time services. The HDR (High Data Rate) system has some characteristics that are different from the CDMA mobile communication system conforming to the existing IS-95 or IS-2000 standard.

The characteristic of HDR, which is one of the mobile communication systems for transmitting wireless data, is that the traffic characteristics of the packet data service are different from those of the voice traffic, so that if the same band is allocated, channel management may be difficult. Use the band of.

Coherent demodulation using the adaptive coding and modulation method and transmission using the maximum power for the forward link (base station to the terminal), and the reverse pilot signal for the reverse link (terminal to base station). coherent demodulation. In addition, various methods are used to adjust the dynamic transmission speed of the traffic channel and to improve frequency efficiency. Here, the forward transmission rate is 38.4Kbps ~ 2.4576Mbps, in the reverse direction to provide each terminal with a transmission rate of 9.6Kbps ~ 153.6Kbps.

The base station in the CDMA1x HDR system manages information coming from various terminals and controls a call to the terminals. In particular, since HDR has characteristics of a mobile station, a method of controlling an effective call is required.

Referring to FIG. 1, the HDR system is largely composed of a terminal 101, a base station 102, and a control station 103. In the base station 102, a plurality of terminals 101 may be connected to the control station. 102 is a system for controlling a plurality of base stations 102.

Referring to FIG. 1, a base station processor (BSP) 102a inside a base station 102 receives and processes signals for a call transmitted from a plurality of terminals 101 in a reverse direction, and signals for various calls. In order to receive and control the overall call and to communicate with the upper control station 103 to transmit to the final terminal.

In addition, the base station processor (102a), in addition to the function to handle the call, a terminal of a constant length (Random Access Terminal Identifier) in combination with the hardware-fixed information and the number randomly generated when the terminal is first powered on (Hereinafter abbreviated as RATI), and for the RATI coming from the terminal, the base station 102 requests the upper control station 103 for an authenticated one-way terminal identifier (Unicast Access Treminal Identifier). The process is done.

At this time, the terminal 101 communicates with the base station and the upper control station with the authenticated UATI information. When the terminal terminates communication, the UATI information is lost.

However, conventionally, when the terminal requests authentication from the terminal to the base station, the base station transmits UATI information, which is a one-way terminal identifier, to the upper control station to request authentication, receives the UATI information in response, and informs the terminal of the authentication if the terminal is authenticated. In this case, the base station does not efficiently manage a call for authentication during initial access in each terminal.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and when a plurality of terminals are connected for initial authentication, a high-speed device is provided for managing and assigning a one-to-one corresponding work number to a unique call of each terminal. An object of the present invention is to provide a method for managing a terminal authentication call of a base station in a data transmission system.

Another object of the present invention is to provide a method for managing a terminal authentication call of a base station in a high-speed data transmission system that enables a queue to manage RATI information and call status with one work block together with a work number for each authentication call. There is this.

Another object is to provide a base station to communicate with a higher control station with a work number assigned to a unique call for authentication of a terminal, so that a high number of authentication calls can be managed more efficiently.

The terminal authentication call management method of the base station in the high-speed data transmission system according to the present invention for achieving the above object,

In a high speed data transmission system, a base station assigns a unique work number to a unique call according to each terminal connection for authentication, and manages the authentication call of the terminal with the work number.

Preferably, the base station communicates with a higher control station by using a work number assigned to each terminal.

In addition, in order for the base station to manage the authentication call of each terminal, a series of operations are performed on a work block configured to correspond to one call one-to-one, a queue managing the work block in a list form, and randomly received signals. It is characterized by having a task to process so that.

Preferably, the work block includes a RATI information for one call, status information for the call, and a series of work numbers for distinguishing each work block.

In the high-speed data transmission system according to another object of the present invention, the terminal authentication call management method of the base station,

After initial setting of the base station, when a signal for requesting UATI information is received from the terminal, assigning one work block to be dedicated to processing the call; Assigning a unique work number to the RATI coming from each terminal; Communicating with a higher control station with a work block assigned the work number to transmit a UATI assignment request signal; If the UATI allocation for the RATI is successful, transmitting the UATI allocation to the terminal and assigning the UATI; And terminating one UATI allocation process for the one terminal.

Here, the initial setting of the base station may include: initializing a queue to be used for a call when the internal system of the base station is activated; Generating a work block through initialization by the work block used in each call; Linking all the work blocks so that the generated work blocks can be arranged in a predetermined order by linking them to a queue; Storing all linked work blocks in a certain order; And generating an endless loop for processing a call when the work block is stored.

Preferably, when one UATI allocation process is terminated for the one terminal, the method further comprises the step of initializing the work block and initializing the queue storage area so that the work block used by the other terminal can be used. .

Referring to the accompanying drawings, a method for managing a terminal authentication call of a base station in a high speed data transmission system according to the present invention as described above is as follows.

First, referring to FIGS. 2 and 3, the base station 202 receives a queue of signals from a plurality of terminals 201 and manages the queues 212 and the work block 222 to manage them. And a task 232 that processes the infinite loop signal.

The work block 222 has RATI information for one call, a state for the call, and a series of work numbers as shown in FIG. 3, and always one call for one call. Arbitrary numbers (Work Block 1, Work Block 2, ..., Work Block n) configured in the form of work blocks are aligned memory areas.

In addition, the queue 212 manages the work block 222 in the form of a link list, and the task 232 of the signal processing waits for randomly received signals and then receives a signal. It is a routine that handles a series of tasks.

4 is an initial operation flow diagram for a base station to manage a call for authentication, in which a queue to be used for a call is initialized when started in the system. That is, the parameters of the queue are initialized (= 0) (S401).

And, the work block used for each call is initialized, in which case the work number of the work block is sequentially assigned initially to generate a work block (S402). The work number here is 0, 1, ..., n. This work block includes the above elements so that the work block can be used as an area for storing elements such as call state, call number, and RATI information of the call.

When the work block is generated and initialized, all the work blocks are linked to be arranged in a predetermined order by linking the generated work blocks to the queue (S403). Thereafter, the work blocks linked to the queue are stored in a certain order (S404).

In addition, an infinite loop for processing the received call is generated and a call processing task is generated (S405).

Figure 5 shows a routine for processing the infinite number of signals coming from the terminal, the base station is in the standby state whether the signal is coming from the terminal (S501), when the terminal receives a signal requesting UATI (S502), One call block dedicated to the processing is assigned to the call (S503).

At this time, one work block is given by reading one record stored in the queue, and the work block is given a unique work number for RATI information coming from each terminal (S504), and information having such work number and RATI. UATI information is transmitted to the upper control station to request authentication (S505). At this time, the base station transitions to the standby state until the authentication request is approved.

Subsequently, upon successfully approving the UATI allocation request for the RATI from the higher control station, the base station transmits and authenticates the UATI information to the corresponding terminal (S506).

These steps S501 to S506 are one UATI allocation process for one terminal. When the UATI allocation process is completed, the base station returns to the original state so that the currently used work block can be used by another terminal (S507). New information is stored in the queue and returned to the initial memory area (S508).

In this way, the base station only communicates with the upper control station with the work number assigned to the corresponding terminal of the work block, thereby saving system resources. That is, the management can be made easier by managing with the work number assigned in the work block instead of managing the RATI information (eg, 32 bits).

As described above, according to the terminal authentication call management method of the base station in the high-speed data transmission system according to the present invention, the base station has a work number assigned to the terminal of the work block and performs communication necessary for call authentication with a higher control station. By managing this, since a unique work number is assigned to a unique call, the call can be managed more easily, and the multiple calls can be easily managed.

In addition, because it manages the work number rather than managing the 32-bit random access terminal identifier, the base station and the control station can more easily manage and control the state of the call or the resource of the call, and can control the number of calls coming from multiple terminals. It can be more effectively managed and supervised.
