Description

How to Handle Operator Commands in Digital Mobile Networks

The present invention relates to a digital mobile communication network, and in particular, the SS7 protocol is used to manage the BMC's Man-Machine Communication (MMC) commands and statistical commands for managing the operation and system configuration information and status information of base stations and control stations of the digital mobile communication network. In a configuration module for processing in a stack, the present invention relates to a method for processing a command of an operator of a digital mobile communication network which can streamline the performance of a function by simplifying related data and processing methods for an MMC command or a statistical command.

Recently, mobile communication service that provided only simple voice service has emerged as next generation mobile communication service such as PCS, IMT-2000, and provides various and complex services such as various additional services, high-speed data service and multimedia service. The signal information transmission method using is not sufficient to provide efficient signal information transmission and service.

Therefore, applying the SS7 signaling protocol recommended by ITU-T to the control station and the exchange period for the purpose of use in digital communication networks and ISDN can prepare a more applicable system network for various services to come in the future. Will be.

When configuring the PCS system, when applying the SS7 signaling protocol according to the IS-634 specification applied to the control station and the exchange, there is a need for the operator to manage and maintain the SS7 signaling protocol stack.

In other words, it is necessary to receive the status and retention information of the SS7 signal protocol stack, accumulate it, output this information if necessary, and apply it to system operation, and change system configuration information by MMC command.

To this end, it is necessary to efficiently configure the operation interface between the BSM and the SS7 signal protocol stack to efficiently process it.

In the conventional mobile communication network, the operation of the control station and the base station is performed through the BSM system operation and maintenance, and even when applying the SS7 signaling protocol will not change the operation method.

Basically, SS7 signaling protocol of ITU-T transmits and receives communication between SS7 protocol stack and management block through TMN.

In the past, SS7 signaling protocols and R2 signaling protocols were mixed between stations that used SS7 signaling protocols. SS7 signaling protocols are also more complex and provide various user parts, thus simplifying the configuration for operation and maintenance.

In addition, since the hardware and software configuration for the SS7 signaling protocol of the exchange is classified by SS7 signaling protocol layer, it has a complicated state machine (STATE MACHINE) for correcting this when reporting MMC instruction processing and processing information.

Therefore, the MMC instruction performance is not guaranteed and more packets and processes for instruction execution occur between processors in which the SS7 signaling protocol is raised to process the instruction packet.

Therefore, the probability of packet loss and error increases, resulting in an increase in the overhead side of the management network due to frequent generation of additional packets other than the actual MMC command processing, resulting in a decrease in efficiency.

The present invention has been made to solve such a conventional problem, and an object of the present invention is to simplify the hardware configuration of the control station for the SS7 protocol and to simplify the SS7 signal protocol signal mode of the control station and the exchange period, that is, point-to-point Based on the IS-634 specification that recommends the (Point-To-Pount) method, it is configured to have a sequential relationship between the instruction processing targets, thereby simplifying the instruction processing and target information to reduce packet overhead and perform operator command functions. It is to provide a way to bring the security of.

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

1 is a diagram showing the relationship between the target items of the present invention, FIG. 2 is a protocol flow diagram for processing a foreign station signal point of the present invention, Figure 3 is a flow chart of the present invention.

The present invention is a problem between the management block and the protocol stack for the operation and maintenance of the SS7 signaling protocol used between stations due to the complexity of the hardware configuration, additional functions for processing it and the overall implementation of the SS7 signaling protocol have.

However, IS-634, which is currently recommended as an interface standard for control stations and exchange periods in PCS, recommends a point-to-point signal mode that applies the SS7 signaling protocol, thereby simplifying network construction for signal information transmission. To provide.

Here, the point-to-point method refers to a method in which two nodes are directly connected to each other in a 1: 1 relationship, and one of the nodes is composed of a processor which is a processing device that is responsible for transmitting and receiving data.

In consideration of such a basic environment, the command processing configuration module for providing operation and maintenance and status management of the SS7 signaling protocol of the control station and the exchange is configured to have a sequential relationship between the processing targets as shown in FIG.

SS7 signaling protocol target items to be managed through BSM's MMC can be classified into four categories.

That is, a set of signal points, signal links, and signal links and subsystems.

First, a signal point is composed of another station signal point (DPC) and a host signal point (OPC), and the signal link set LSET is a set of links connected between signal points and may have multiple signal link sets at the signal point.

The signal link LNK is a path through which actual signal data flows, and up to 16 signal points may be configured for one signal point, and a sub system may mean up to 256 end users performing services.

In the definition step, the local signal point (OPC), the other station signal point (DPC), the link set (LSET), and the link (LNK) must be defined in advance, and the deletion step has the above prerequisites in the reverse order to the definition step. Since the BSM MMC command is processed, the precondition is searched first when the command is received, thus eliminating the case of requesting processing or checking the status up to the SS7 signaling protocol stack.

That is, in the case of defining / deleting a link (LNK), link set (LSET), station signal point (DPC), and host signal point (OPC), etc., the stack manager area serving as an interface between BSM and SS7 signaling protocol is processed. Later, the command is requested to the stack, but no response is required, thereby reducing the packet overhead that may occur when sending and receiving a control packet with the SS7 signaling protocol stack.

In addition, it is possible to reduce the occurrence of a process for performing various additional functions in the protocol stack area, thereby increasing the guarantee of the function execution.

In other words, management is managed through MMC between the operating system and the stack where N0.7 is actually operated. This information is formed into PLDs, and the MMC packet is actually reconstructed these PLDs. Since the guarantee of the command is reduced, the SM basically determines the length of the packet and whether or not the upper PLD data is defined, and then takes the response to the BSM and performs the PLD on the stack. Start over and rebuild.

In other words, the execution of the MMC instruction is performed on the SM once, and then related work is performed by calling the reconfiguration primitive to the NO.7 stack according to the reconstructed PLD.

FIG. 2 is a protocol flow diagram generated between a base station operator (BSM) ↔ stack manager (SM) ↔ protocol stack (STACK) when defining / deleting another station signal point (DPC). By reducing the overhead of the packet, it is possible to provide a guarantee of function execution by reducing an exception that may occur when receiving an operator command and performing the corresponding function.

That is, referring to Figure 2, after the DEFINE-DPC transmission determines whether the packet length and OPC is defined in the standby state (S1) or if the return to the S1 again and if it is correct, restart the NO.7 PLD to send the response message to the S1 (S3), NO. 7 Determines whether to start stack relocation, and transmits an alarm message when reconfiguration fails (S4).

Here, the transmission of the configuration request message in the process of restarting NO.7 of S3.

In addition, the MMC instruction is performed up to S1-S3, and operations between the SM and the N0.7 stack are performed from S3 to S4.

As described above, the present invention has the effect of efficiently and simplifying the MMC instruction processing structure and the target information, thereby reducing packet overhead and providing guarantees of performing operator instruction functions.
