Description

Apparatus and Method of Managing Common Resources in the Communication System

The present invention relates to an apparatus and method for managing a common resource in a communication system, and in particular, assigns a common resource corresponding to various unpredictable data and services required by a subscriber in a communication system, and assigns the common resource in various forms. The present invention relates to a common resource management apparatus and method in a communication system for efficient management in accordance with the present invention.

In general, resource management in a communication system refers to managing a usage situation such as a device required for processing a task, a storage area, or a call path required for processing a connection of a call. Since system resources are used according to various tasks, In resource management, the system system manages whether the system resources are empty or blocked, and provides resources according to a request from a user program.

In other words, when a request for registration of a new resource is received from an operator or a user, all resources constituting the communication system are searched for by a database in which the requested resource is already registered. If the requested resource is not registered, add the requested resource to the database, and add functions to perform the service according to the added resource.

In addition, when an operator or user transmits a command for deleting resources for a service that is not needed, the operator detects this and deletes the corresponding resources registered in the database so that services of currently running resources can be smoothly performed.

On the other hand, in the conventional communication system where there are not many kinds of services, there is no problem even if the necessary resources are registered or deleted according to the service in the database. However, due to the rapid development of the communication system, subscribers have various forms. As data and services are required and the required services are not predictable, there is a need for a method for efficiently processing and managing resources according to each type of service that is unpredictable.

The present invention allocates common resources corresponding to various types of unpredictable data and services required by subscribers in a communication system, and efficiently manages the corresponding common resources according to various types, thereby preventing prediction. It is an object of the present invention to provide a common resource management apparatus and method in a communication system so as to adequately respond to the needs of various services.

In addition, the present invention is configured to efficiently process and manage common resources in a communication system to process a service suitable for each data type of a wireless subscriber such as IMT-2000, so that each resource of the system separately The purpose of this is to efficiently respond to services that are difficult to predict how much the service is.

The main controller 21 is responsible for communication for performing control signals with the upper main processor matching unit 11 by IPC matching and data communication with the ATM matching and processing unit 12.

The memory unit 22 stores a program and related data necessary for controlling the operation of the main controller 21.

The bus arbitration unit 23 controls the arbitration right of the bus for the main control unit 21 and the resource type initialization generation unit 25 to access the common resource unit 14.

The occupancy and available channel state checker 24 is a register part for the main control unit 21 for managing the current channel of the common resource unit 14, and controls the currently available channel under the control of the main control unit 21. Sends the signal of the number of bits corresponding to the type of the subscriber and the capacity of the subscriber (that is, the type) corresponding to the type and the capacity of the subscriber to identify the channel and the type to the resource type initialization generator 25. Check that the current data is the channel that meets your requirements.

The resource type initialization generation unit 25 is composed of CPLD logic, decodes a signal received from the main control unit 21 to access a channel of the common resource unit 14, and an initialization command. Through this, the common resource unit 14 is initialized in a specific form according to various forms, and a call is sent to a specific channel and the corresponding information is stored in an internal register. In addition, the resource type initialization generator 25 receives the clock generated by the clock generator 27 to obtain an address, a data signal, and a bus use arbitration right by using a counter.

A common resource management method in a communication system according to an embodiment of the present invention will be described with reference to the flowchart of FIG. 3. Here, the ATM matching and processing unit 12 to describe the call progress of the system taking the case of the connection request to a specific subscriber among the IMT-2000 wireless terminal subscribers, but the present invention is not limited to this in common resource management It should be well understood.

First, in ATM matching of the ATM matching and processing unit 12, it checks what type of call the current call is, and informs the main processor matching unit 11, so that the main processor matching unit 11 includes a resource management and processing unit ( 13) and IPC matching to apply the control signal.

Accordingly, the main control unit 21 in the resource management and processing unit 13 receives a control signal from the upper main processor matching unit 11 through IPC matching and confirms what type of call the current call is (step S1). Check whether an available channel connection request for connecting one available channel is received (step S2).

At this time, when the available channel connection request is received, the main controller 21 controls the occupancy and available channel status checker 24 in the resource management and processing unit 13 to check the currently available channel ( Step S3), the signal of the number of bits corresponding to the type of the subscriber and the capacity of the subscriber on the system capable of distinguishing a certain channel and the type (i.e., the type) is stored in the resource management and processing unit 13. It sends to the resource type initialization generation part 25 (step S4).

Then, the resource type initialization generation unit 25 decodes the signal received from the main control unit 21 and accesses the channel of the common resource unit 14 (step S5). The common resource unit 14 is properly initialized (step S6), a call connection signal for opening the channel is transmitted to the common resource unit 14, and the matter is stored in an internal register (step S7).

In this case, since the resource type initialization generation unit 25 needs to be able to access the call connection signal to the common resource unit 14, the resource type initialization generation unit 25 generates the clock connection unit 27 in the resource management and processing unit 13. By using the counter, the counter can be used to obtain the address, data signal, and bus arbitration rights. Also, it is possible to configure the initialization signal for each type to limit the bus license for more than a certain time. To do it.

In this way, the function of limiting the bus usage rights over the predetermined time and the function for the call connection command are performed by using the CPLD logic inside the resource type initialization generation unit 25, thereby overloading the main control unit 21. Can be reduced.

Then, it is checked whether the call is connected by the call connection signal (step S8). At this time, when the call is connected, the value is recorded in a register inside the resource type initialization generation unit 25 (step S9). And the interrupt signal INT generated by the address and data multiplexer 26 in the processor 13 to the main controller 21 (step S10).

Accordingly, the main controller 21 controls the occupancy and available channel state checker 24 to check whether the current data is a channel that meets its requirements (step S11). A request is made to the bus arbitration section 23 in the processing section 13 (step S12).

Accordingly, the bus arbitration unit 23 transfers the bus right to use the main control unit 21 according to the request of the main control unit 21 (step S13), whereby the data path is transferred from the address and data multiplexer unit 26 to the main control unit ( 21, data is received, and the received data is stored in the memory unit 22 in the resource management and processing unit 13 (step S14).

In addition, the main controller 21 notifies the main processor matching unit 11 of the call connection state (step S15), and transmits and receives data with the ATM matching and processing unit 12 through a data communication channel to the subscriber side and the data. Communication is enabled (step S16).

In the present invention as described above, there may be a voice subscriber, a modem subscriber, an ISDN subscriber, a fax subscriber, or the like as a communication type subscriber with a wireless terminal subscriber. In the case of requesting communication with the subscriber, the upper main processor matching unit 11 checks what type of call is present and requests an incoming call, and performs the above-described operation.

As described above, according to the present invention, a common resource corresponding to various unpredictable types of data and services required by a subscriber in a communication system is allocated, and the common resource can be efficiently managed according to various types. In other words, the resources of each system can be set aside so that the proper use of system resources can be achieved by appropriately responding to a service that is difficult to predict how much a service is.
