The present invention relates to a message distribution processing apparatus and a control method of the number seven signal network system, and in particular, the available SCCP user unit linked to a number of SCCP user units operating in the No.7 signal network in a round robin manner linked The present invention relates to a message distribution processing device and a control method of the number seven signal network system that stores in a list form and performs distributed processing in a round robin manner with reference to a linked link when a CR message is input from a large station.

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 base station controller (RNC), a core network, and the like, which are generally configured in a network form to process radio signals transmitted and received from a mobile terminal. In addition, in the network systems, for example, a core network and an RNC may be connected to each other through a NO.7 signal network to transmit and receive messages.

Here, the No. 7 signaling system is different from a conventional call system in which a call path and a signal path are used together, so that a plurality of voice signals are separated from each other by completely separating the call path and the signal path. A common line signaling method for transmitting and receiving signal information through one channel. A network using the No. 7 signaling method is called a No. 7 signaling network, and a signaling entity distinguished from the No. 7 signal network is called a signaling point.

However, the system using the conventional No. 7 signal network as described above is a system for exchanging messages with each other, as shown in FIG. 1, for example, the processor boards 71A-N of the switch 70 and the switch 70. MTP (Message Transfer Part: 74A-B) which actually processes a message in a plurality of RNCs 73, which is a large station connected to the NO.7 signal network 72, and processes the message with the NO.7 signaling protocol. SCCP (Signaling Connection Control Part: 75A-B), SCCP user unit (76A-B) for controlling the connection connection signal received by the SCCP (75A-B) or other call transfer function, for example, a signal of the RANAP type Are respectively provided.

Here, the No. 7 SCCP user unit 76A-B must perform a connection procedure with the power station in order to transmit a message with guaranteed order to the power station, and establish a connection with the No. 7 SCCP 75A-B. The primitives used by the SCCP 75A-B and the SCCP user unit 76A-B are composed of four elements: an N-CONNECT request, an N-CONNECT indication, an N-CONNECT response, and an N-CONNECT confirm.

The connection between the two signaling points in which the connection is established is divided into 24 bit connection identifiers (CIDs) and transmits / receives a message requiring an order guarantee using a Direct Transfer (DT) message of SCCP.

On the other hand, looking at the message processing method of the system using the conventional No. 7 signal network as described above, the SCCP user portion 76B of the large country, for example, the RNC 73 to the SCCP user portion of the own station to ensure the message transmission In order to do so, a CR (Connection request) message is sent to the SCCP 75A of the exchange, for example, the exchange 70. At this time, the CR message includes a CID as shown in FIG. 2 used by the power SCCP 75A and the SCCP user unit 76A.

The MTP 74A of the specific processor 71A receiving the CR message transmits the received message to the SCCP 75A of the same processor, and the SCCP user unit 76A also located in the same processor. The N-CONNECT indication primitive sends a message. Then, the SCCP 75A and the SCCP user unit 76A store the CID sent from the power. At this time, the SCCP user unit 76A transmits to the SCCP 75A using the N-CONNECT response primitive in response to the CR message. The SCCP user unit 76A and the SCCP user unit 76A of the local station send the SCCP user unit 76A. There will be a CID to use. In addition, the SCCP 76A stores the information included in this primitive together with the location where the CID of the power is stored, and stores the information until the connection is released. In addition, when the SCCP user unit 76A-B configured as described above requests the SCCP 75A for data transmission with an N-DATA request primitive, the SCCP 75A uses the DT message to SCCP the country. Send user part message. In this DT message, a CID for identifying a connection exists. Therefore, by processing the CR message requested by the SCCP user portion 76B of the RNC 73 in a one-to-one manner, the processing sequence of DT messages having the same CID is guaranteed.

However, the message processing method of the system using the conventional No. 7 signal network as described above, only the SCCP user unit, the SCCP and the MTP in which the No. 7 SCCP-connected message transmission is located in the same processor are transmitted / received. Responding to the connection establishment required by the power when the SCCP user part is not present on the processor or the SCCP user part of the processor is unavailable due to various failure factors or when the SCCP user part transitions to Out-of-Service status As a result, the SCCP user of a large country can no longer request a connection setting, so the usability of the system is remarkably degraded. Also, if a connection setting is concentrated on a specific processor, there is a means for properly distributing it. Because the processor is overloaded, Down so frequently happens that this problem is also the reliability of the system is significantly reduced were generated accordingly.

Accordingly, the present invention has been invented to solve the above-mentioned conventional problems. Since the message is distributed without being processed depending on a specific processor in the system, the message of the number seven signal network system can be maximized accordingly. Its purpose is to provide a distributed processing apparatus and a control method thereof.                         

Another object of the present invention is to include a CID signal in the connection procedure signal, so that only the CID signal is separated and the message is distributed to a processor that can be surely used, thereby improving the reliability of the system. The present invention provides a message distribution processing apparatus and a control method thereof.

In order to achieve the above object, the present invention provides a network system for transmitting and receiving a message using a NO.7 signaling network. It stores the SCCP user part that processes the signal including the signal designating the specific processor and the available SCCP user parts of the country including the SCCP user part in the form of a linked-list. SCCP block that transmits CC message with distributed processing in the round robin manner and sets the factor value to distinguish the processor in the first 5 bit area of the CID parameter according to the CR message response, and the message processed by the SCCP block. A MTP block that actually processes the data and transmits the CR message received from the specific processor of the power station to the SCCP block. Provides a message distribution processing device of the Verseven signal network system.

Another feature of the present invention is a linked list storing step of storing an available SCCP user part in a linked list form of an SCCP block of a network system using a NO.7 signaling network, and receiving a CR received from the power after the linked list storing step. The first CR message acknowledgment step to confirm whether the message is the first received message, and if it is confirmed that the CR message received by the CR message first acknowledgment step is not the first received message, it is in the SCCP block of the first designated processor. The available processor selection step of selecting the next available SCCP user part from the provided linked list, and if it is confirmed that the CR message received by the CR message initial reception step is the first received message, the SCCP user part recognizes it through the CR message. It stores the CID and other information of one station and outputs the response signal to the SCCP block. After the signal generation step and the response signal generation step and the available processor selection step, the CC message that sets the processor identifier in which the available SCCP user part is located to a specific bit group of the CID is encoded while encoding the CC message input from the SCCP user part. CC message transmission step and CC message reception processing step of analyzing the specific bit group of CID included in the message received from the power station after the CC message transmission step and selecting the processor where the corresponding SCCP user part is located and transmitting the message to the selected processor. Provided is a control method of a message distribution processing apparatus of a number seven signal network system.

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

The apparatus of the present invention is applied to equipment such as a system for sending and receiving messages, for example, a core network 2 having a plurality of processors 1A-N and a plurality of RNCs 3 forming a power station with the core network.

At this time, each of the equipment (2, 3 ) designates a specific processor of the power to the specific bits of the CID of the CR (Connection request) message for message transmission using the NO.7 signaling network as shown in FIG. SCCP user block (4A-N) and the available SCCP user part of the host, including the SCCP user block (4A-N) and the like, are stored in the form of a linked-list. SCCP block 5A-N which performs distributed processing in the round robin manner with reference to the message, and actually processes the message processed by the SCCP block 5A-N, and SCCP receives the CR message received from a specific processor of a large country. And a message transfer part (MTP) block 6A-N for transferring to blocks 5A-N .

Here, the SCCP user blocks 4A-N process data processing with the SCCP blocks 5A-N as, for example, signals of the RANAP type. In addition, the CR (Connection request) message refers to a message requesting a signal connection to the power station when transmitting and receiving data between two signal points of the own station and the power station. In addition, the CC message is a response from the SCCP user unit with an N-connect response. The received SCCP block is the SCCP block of the counterpart station. As shown in Fig. 5, the SCCP block is a message sent by setting the factor value to distinguish the processor in the first 5 bit area of the CID parameter.

Next, a control method applied to the apparatus of the present invention as described above will be described.

As shown in FIG. 4, the present invention proceeds to the linked list storing step S2 in the initial state S1, and stores the available SCCP user units in the form of a linked-list in the SCCP block. After the linked list storing step S2, the CR message is first received and judged in step S3 to determine whether the received CR message is the first received message. In addition, if the received CR message is not the first received message as a result of the CR message initial reception determination step (S3), proceed to the available processor selection step (S4) in the linked list provided in the SCCP of the first designated processor Select the next available SCCP user part.

On the other hand, if the received CR message is the first received message as judged during the CR message initial reception step (S3), the process proceeds to the response signal generation step (S5) and the SCID user unit recognizes the CID and the CR message through the CR message; Save other information and output the response signal to SCCP. After the response signal generation step S5, the response signal reception processing step S6 is performed to receive and process the response signal according to the CR message from the corresponding SCCP user unit. In addition, after the response signal receiving processing step (S6) proceeds to the CC message transmission step (S7) while encoding the CC message while setting the processor identifier located in the SCCP user unit to the specific bit group of the CID transmits the message.

In addition, after the CC message transmission step S7, the CC message reception processing step S8 is performed to analyze a specific bit group of the CID included in the message received from the power station to select a processor in which the SCCP user unit is located. After the CC message receiving processing step (S8), the process proceeds to the available judgment step (S9) to determine whether the currently selected SCCP user unit is available. At this time, if it is determined during the usability determination step (S9) that the currently selected SCCP user unit is not available, proceed to the data discard step (S10) to discard the data. However, if it is determined during the usability determination step S9 that the currently selected SCCP user part is available, the process proceeds to the data delivery step S11, where it is newly distributed and transfers the data to the selected SCCP user part as an N-DATA indication.

In other words, the SCCP blocks 5A-N of each processor 1A-N of the core network 2 using the NO.7 signal network 7 are first available to the available SCCP user part 4A-N of the host. ) In the linked-list format. That is, the SCCP block 5A-N stores the available SCCP user part 4A-N in the form of linked-list. For example, when there are a plurality of available SCCP user parts, it refers to any first available SCCP user part. It stores the indes (number) and the actual process ID and a pointer value indicating the next available SCCP user part to the rear of the actual process ID as a data structure. In other words, the available SCCP user parts are stored in a link state that refers to the next SCCP user part.
At this time, if a CR message is input from a large station, for example, the RNC 3, the MTP blocks 6A-N receive the CR message and transmit the received CR message to the SCCP block 5B using the same processor 1A. Then, when the input message is the first CR message , the SCCP block 5B transmits and processes it to the available SCCP user part 4A located in the same processor. However, if the currently received CR message is not the first CR message, the SCCP block 5A transmits the message to an available SCCP user part 4N located in another processor 1N among the SCCP user blocks stored in the linked list. .

In other words, when the SCCP blocks 5A-N receive a CR message with the MTP-Transfer indication primitive from the MTP block 6A-N, the SCCP blocks 5A-N are CR in a round robin manner for the available SCCP user part 4A-N. Distribute the message

At this time, the SCCP block (5A-N) is the first message received by the SCCP block (5A) of the processor 1A and the SCCP user unit 4A located in the same processor (1A) is available. This SCCP is delivered to the user part 4A using the N-CONNECT indication primitive. Then, the SCCP user part 4A stores the CID of the received CR message, the signal point information of the power that transmitted it, other necessary information, and information on the SCCP user part 4A of the own country that received the message together with the response. Is output to the lower SCCP block 5A.

The SCCP block 5A receives an N-CONNECT response from the SCCP user unit 4A with respect to an N-CONNECT indication, and then the first 5bit region of the CID parameter of the CC message to be transmitted so as to identify the corresponding processor. As shown in FIG. 5, the processor distinguishable number is set to a factor value and transmitted to the counterpart station, for example, the RNC 3. At this time, the SCCP block 5A stores the information including the CID included in the CC message where the information of the CR message corresponding to the CC message is stored.

Herein, the above-described process is mainly focused on the SCCP block 5A which directly receives the CR message. However, since the SCCP user block receiving the CR message is not available, the distributed CR message is received in a round roving manner and then the SCCP block is received. Also works the same as the above process.

On the other hand, when the SCCP block 5B of the large station receives a data message for the SCCP user part 4B with the MTP-Transfer indication primitive from the MTP, this is a DT message and is included in the CID or CC message included therein. The CID of the processor finds the processor and delivers the N-DATA indication to the SCCP user unit 4A located in the processor.

Here, the SCCP block 5B sets the first 5 bits of the CID to be included in the CR when the SCCP user part of the local station first requests to establish a connection to the power station. Send it.

As described above, the present invention stores the available SCCP user part in the form of a linked list in which a plurality of SCCP user parts operating in No. 7 signaling network can distribute messages in a round robin manner, and when a CR message is input from a large country, the linked message is linked. By distributed processing in a round roving manner with reference to the ringst, the message is distributed without being processed depending on a specific processor in the system, thereby maximizing the usability of the system.

In addition, according to the present invention, since the CID signal is included in the connection procedure signal, only the CID signal is separated, and the message is distributed to the processor that can be surely used, thereby improving the reliability of the system.
