An application program matching device must be implemented between the user of the signal connection controller and the protocol stack for communication between the common line signal (SS No. 7) protocol and the personal mobile communication exchange period. In order to test the call processing performance of the mobile subscriber service device of the personal cellular communication exchange, the call shall be generated through multiple call generators to provide overload to the exchange. In the present invention, a communication path is constructed by utilizing a UNIX message queue system between a protocol stack and multiple mobile terminal processes.

"Greensprings" Multicommunication Protocol Dedicated Hardware Board (IPCOMM-302) (1) is a hardware device that handles message transport layers 1 and 2 of the common line signal (SS No. 7) protocol stack. " Motorola's VME Bus matching board (MVME162) (2) supports the matching function between the message transfer layer through the input / output dedicated device (IOP) and the system bus (VME BUS). The message transfer part (MTP) layer 1 (3) is a device for converting a signal from the message transfer layer 2 into an EIA-422 signal, and the MTP layer 2 (4) is responsible for the message transfer layer 2 function. The real-time operating system 5 is responsible for process scheduling and timer management functions between protocol stack layers.

The message distribution device 13 is responsible for distributing a message to a plurality of terminals according to a unique identifier.

3 is a flowchart illustrating an embodiment of a method for distributing a common line signal (SS No. 7) according to the present invention.

In order to control the function of the common line signal (SS No. 7) message distribution device by receiving a management message of the common line signal (SS No. 7) protocol, which is generated at irregular intervals, the communication path 21 and The communication path 22 between the message distributor and the protocol stack is established. If the communication path setting fails, the operation is terminated (23).

The interrupter processor for all interrupt signal processing is driven (24), and data of the global variables and structures of the common line signal (SS No. 7) message distributor is initialized (25).

Common Line Signal (SS No.7) The message distribution device must operate as a memory-resident process for processing events from mobile terminals and exchanges, so that the common line stack for request and notification of call processing-related messages. Upon monitoring the matching event (26) and monitoring the stack manager status information and receiving the stack status management message processing event of the protocol from the exchange (27), the stack status management message is analyzed and requested according to the unique identifier recognized by the signaling connection controller. Deliver information to the terminal. That is, the request function included in the event must be processed (28). It also monitors 29 call setup request and response messages from a large number of mobile terminals. Thereafter, while performing the common line stack matching event repeatedly from the monitoring process 26, the event processing routine is called when the corresponding event occurs.

As a request message from the exchange, events such as connectionless service 31, connection service signal connection establishment 32, data transmission 33, connection release 34, and the like occur.

When receiving a connectionless service message including a message such as a paging or a handover request (35), the received message is decoded and the called terminal number is retrieved (36). The service user identifier and the service provider identifier are found in the access pointer (SAP) and the connection data management based on the called terminal number in the received message (37). Using the service provider identifier and the service user identifier information, a message queue type, which is a communication path identifier between the called terminal and the common line signal (SS No. 7) message distribution device, is obtained (38). It transmits and returns a reception layer 3 message to a process of a corresponding terminal through a message queue system call of UNIX (39).

Upon receipt of a connection type service signal connection establishment, data transfer, and disconnection message (32, 33, 34), the event structure of the connection control head is interpreted (40), so that the service provider instance is the only service identifier between the message distributor and the protocol stack. An identifier is obtained (41), and a corresponding service user instance identifier, service user identifier, and service provider identifier are found (42). The message queue type of the called terminal is obtained using the service provider identifier and the service user identifier (38). It transmits and returns a reception layer 3 message to a process of a corresponding terminal through a message queue system call of UNIX (39).

Upon receipt of the initial request from the mobile terminal (51), a service access block pointer associated with the same server system number through a stack identifier, server system number (SSN), and processor identifier is allocated for communication with multiple mobile terminals and exchanges. The service provider identifier for the terminal is returned (52).

Upon receiving the connection request from the mobile terminal (53), the service provision for the terminal is allocated a service access pointer (SAP) for the identifier and the connection information data management block (54). In the connection information data, a service provider instance identifier between the mobile terminal and the message distribution device is allocated to the connection identifier currently in the "idle" state (55). A user connection block is defined with the mobile terminal and protocol stack of the message distribution device (56).

When the mobile terminal receives a message transmission event from the mobile terminal (57), it allocates a service access pointer (SAP) for the service provider identifier for the terminal, retrieves the user connection block (58), and sends a data transmission layer () for message transmission. Signaling control unit (SCCP) head information for a common line signal (SS No. 7) protocol message such as UnitData, Layer 2 (Data Type 1), and Connection Request is generated (59). Then, the SCCP user data is generated from the user message of the “IS-634” standard of the mobile terminal (60), and the status information of the user connection block is updated to the data transmission state (SU_STE_DAT) and the message is transmitted through the message queue. Is transmitted to the exchange (61).

When the mobile terminal receives an event for receiving a call forwarding request message from the mobile terminal (62), it allocates a service access pointer (SAP) for the service provider identifier for the terminal, retrieves the user connection block (63), and connects the called terminal number. Copies to the terminal address area of the block (64) and registers to the reception list (65).

When the mobile terminal receives the disconnect request event (66), it retrieves the service user instance identifier (67), updates the list for the receiving terminal (68), and the message distribution device and the common line signal (SS No. 7) protocol. The connection is released by deleting the connection with the stack and deleting the service access point (SAP) and the service provider identifier between the message distribution device and the terminal (69).
