Description

Mobile communication base station management apparatus having an application process dispersion processing structure

The present invention relates to a mobile communication base station management apparatus having an application process distributed processing structure, and more particularly, to distribute a plurality of application processes having the same function as a BSM, and to allocate a message ID to each distributed process to assign a message identification number. The present invention relates to a mobile communication base station management apparatus having an application process distributed processing structure for processing packet data.

In general, UMTS (Universal Mobile Telecommunication System) networks can transmit "third generation", broadband packet-based text, digitized voice or video, and multimedia data at high speeds of more than 2 Mbps, whether mobile or computer users are anywhere in the world. Provide consistent service. This UMTS network allows computer and telephone users to continue to access the Internet while traveling and have the same performance no matter where they are traveling. Users will use this UMTS service through a combination of terrestrial radio and satellite transmission technology. However, such a UMTS network includes a base station (Node-B), a radio network controller (RNC), a base station manager (BSM), and the like, which are generally configured in a network form to process radio signals transmitted and received from a mobile terminal. Doing. Here, the BSM is a system for managing a plurality of base stations and base station controllers in the form of a node element (NE), and transmits and receives data packets to one NE through an IPOA (IP OF ATM) type TCP / IP connection.

Then, referring to FIG. 1, the process management apparatus of the conventional BSM apparatus as described above is connected to a plurality of base stations 70A-N to manage the base stations and output the processed transmission data in the form of IPOA TCP / IP. An RNC 71A-N and a BSM 72 that receive and process packet data of the RNC 71A-N by a process generated by being connected to the RNC 71A-N in an NE form.

Here, the number of NEs, which are the type of connection between the RNC and the base station (node-b) connected per RNC, is generally limited to 1024.

In addition, the BSM 72 is provided with a data communication interface (DCI) block 73 which is in charge of TCP / IP communication with the NEs, and the DCI block 73 has a socket for transmitting and receiving ( socket) There is one communication responsible process, and the maximum number of connections that one process can handle is 1024. The BSM 72 includes a message queue 74A-N for storing data received from the process of the DCI block 73, and the other end of the message queue 74A-N has the same function. The application process 75A-N which connects is connected.

That is, the application process 75A-N includes n application processes having the same function according to the type of signal. For example, the BSM 72 usually includes eight application processes for handling failures or states. . Each of the application processes is connected with one message queue 74A-N.

On the other hand, referring to the operation of the process management apparatus of the conventional BSM device as described above, first, when the manager of the BSM 72 wants to obtain information from a specific base station, the data is requested through the generated application process 75A. At this time, the CPU (not shown) of the BSM 72 transfers the request data processed through the corresponding application process 75A to the DCI block 73 through the transmission message queue (not shown). Then, the process of the DCI block 73 processes the input request data by the TCP / IP protocol of the IPOA and routes it to the base station 70A. Here, when the corresponding base station 70A responds, the response packet data is again processed by TCP / IP by the RNC 71A of the corresponding NE and then transmitted to the socket process of the DCI block 73 of the BSM 72. do.

Accordingly, the socket process of the DCI block 73 of the BSM 72 processes the received packet data and outputs the received packet data to the message queue 74A connected to the corresponding application process 75A. Then, the application process 75A of the BSM 72 reads and processes the input message from the message queue 74A and outputs data desired by the user to the outside. At this time, the message queue 74A can process 600 pieces of data of 1Kbytes.

Here, when the application process 75A in the BSM 72 is driven during the process, the kernel in the BSM 72 is scanned and processed.

However, the process management apparatus of the conventional BSM apparatus as described above has a structure in which one application process processes a function, for example, a fault or a status signal, and the capacity of the message queue connected to this single application process is also 1 kbyte of data. It can handle about 600kbytes per queue, so it can handle about 600kbytes per queue, so the expansion loads caused by the recent increase in subscribers or call quality, for example, 16 RNCs and 128 Node-Bs per RNC, are transmitted over 2K in total. Since the internal IPC (inter processor communication) load caused by the communication with the node element (NE) could not be handled, the application process was frequently down, thus causing a problem that had a fatal effect on the operation service of the BSM. .

Accordingly, the present invention has been invented to solve the above-mentioned general problems, and even if the load of the internal IPC is continuously increased, the application process is distributed and processes the distributed application process to stably execute the operation of the BSM accordingly. It is an object of the present invention to provide a mobile communication base station management apparatus having a processing structure.

Another object of the present invention is to separate the packet data received by the DCI block according to the message identification number and transmit the message to the message queue connected to the corresponding application process, so that the processing process does not exhibit a down phenomenon due to an overload. It is to provide a mobile communication base station management apparatus having an application process distributed processing structure that does not affect the function.

The present invention for achieving the above object is a process processing apparatus of the BSM of the UMTS network of the NE form, a plurality of application processes for separating and processing a plurality of message signals having the same function through the message identification number, and A plurality of message queues storing messages received in connection with each of a plurality of application processes, and a DCI analyzing the message identification number of the message received from the NE and transmitting the received message signal to a message queue connected to the corresponding application process. A mobile communication base station management apparatus having an application process distributed processing structure composed of blocks is provided.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The apparatus of the present invention is a packet of the RNC (1A-N) by a process generated in connection with the NE form consisting of a network combination of a plurality of base stations (2A-N) and RNC (1A-N) as shown in FIG. Applied to the BSM 3 for receiving data.

That is, the apparatus of the present invention includes a plurality of application processes 5A-B and 6A-B for separating and processing each of the application processes 4A-N having the same function through a message identification number, and the plurality of application processes. A plurality of message queues 7A-B and 8A-B for storing messages received and connected to each of the application processes 5A-B and 6A-B, and a message identification number of the message received from the NE. It consists of a DCI block 9 which analyzes and transmits the received message signal to message queues 7A-B and 8A-B connected to the corresponding application process.

Here, each of the first and second message queues 7A-B and 8A-B processes a message of about 1200 Kbytes.

Next, the operation and effects of the present invention as described above will be described.

The apparatus of the present invention requests data through corresponding application processes generated when an administrator of the BSM 3 wants to obtain information from a specific base station. In this case, the application process of the BSM 3 has the same function, for example, a fault alarm. Each application process for processing the status information is divided into a plurality of, for example, two, so that any one of them processes the message signal.

For example, when the application process 4A is a process that is in charge of the fault alarm alarm function, the application process 4A is divided into a first application process 5A and a second application process 5B. 5A-B) is a message identification number that can identify its own area in the message signal that it processes, for example, the first application process 5A is "MS001" in the message signal, and the second application process 5B is a message. Differently from the first application process 5A, the signal is given to the message signal as "MS002" and transmitted to the desired target NE via the DCI block 9.

Here, when the base station 2A of the target responds, the response packet data is again processed by TCP / IP by the RNC 1A of the corresponding NE, and then the process of the process of the DCI block 9 of the BSM 3 is performed. It is received through the transmission port.

Then, the process of the DCI block 9 analyzes the routing information of the received packet data. In this case, when the routing information of the packet data is a signal ("MS001") transmitted to the first application process 5A, If it is loaded into the first message queue 7A connected to the first application process 5A, while the routing information of the received packet data is a signal ("MS002") transmitted to the second application process 5B, Load into the second message queue 7B connected to the second application process 5B.

Then, the first or second application process 5A-B having the same function polls the input message from the message queue 7A-B connected thereto, processes it, and processes it into data desired by the user. To the output. Here, when the application process in the BSM 3 is driven during the process, the kernel in the BSM 3 is scanned and processed.

Therefore, according to the process of the present invention as described above, a single application process that performs the same function, that is, processing a fault alarm or a state, is internally distributed into two again, and each distributed application process processes the signal Because different message identification numbers are sent to the receiver and received and processed again, the NE can be smoothly processed even if the load of the IPC increases due to various reasons.

In addition, since the capacity of the message queues 7A-B and 8A-B connected to each of the application processes 5A-B and 6A-B can handle more than 1200 Kbytes, even if the ME increases to more than 2K, the processing is sufficient. .

As described above, the present invention distributes a plurality of application processes that perform the same function of the BSM, and allocates a received message queue to each distributed process to process packet data through a message identification number. The application process is distributed and processed even though it is continuously increased, and thus has the advantage of having an application process distributed processing structure that makes the operation of the BSM stable.

In addition, according to the present invention, since the packet data received by the DCI block is classified according to the message identification number and then transmitted to the message queue connected to the corresponding application process, the processing process does not exhibit a down phenomenon due to an overload. There is also an effect that does not affect the communication function.
