摘要： PURPOSE:To make a fault information storage area to be small capacity and to accelerate trouble statistics processing by analyzing an occurring fault and making only the fault cause of a circuit specified from a host among the fault cause occurring to logic circuits as an object to be tabulated. CONSTITUTION:A microprocessor (MPU) 1 steps a physical trouble fault 52 at every fault cause every time when a physical circuit fault is informed from a circuit interface part 3 through a bus 8. On the other hand, it zero-clears a logic circuit fault counter 53 when it receives a monitoring link setting command through the high-order system interface part 4 and the bus 8 and registers link identification information among the command to a monitoring information identification area 50. At the step follow of the counter 53 after receiving the command, control link identification information is extracted from the address field 101 of a reception frame and set to a control link identification area 51. Next, procedure processing is executed and the contents of the areas 50 and 51 are compared when a procedure error exists. When the contents of them coincide each other, the corresponding fault counter is stepped. Therefore, the contents is tabulated on the counter 53.

摘要： PURPOSE:To speed up the recognition of the succeeding state regulated by a state matrix necessary for communication control and the execution of processing, by executing the retrieval of a state transition matrix and branch to processing obtained as the result of retrieval within the execution time of one instruction. CONSTITUTION:A state transition table circuit 320 is addressed by an output from an input event register 311 and an output from a current state register 312 and outputs a succeeding state code and a processing code respectively to a succeeding state register 332 and a processing code register 331. The succeeding state code stored in the register 332 is stored by a CPU so as to correspond to the circuit and the processing code stored in the register 331 is utilized for the address of the corresponding program. In this case, the circuit 320 is constituted of a RAM, a ROM, etc., and allowed to establish a new value until the execution of the succeeding instruction after executing one instruction and to obtain a processing code and the succeeding state by the succeeding instruction after setting up the sort of an input event and the sort of the current state in respective registers. Thus, the retrieving processing of the state transition matrix can be speeded up.

摘要： PURPOSE:To allow a predetermined mobile equipment to receive a call even when the call reception registration is released. CONSTITUTION:When a mobile equipment moves between networks and makes a position registration request (S1), a database 43 of a resident zone network C makes a position registration request to a home network of the mobile equipment (S3), and a database of the home network A returns its mobile equipment information and a subscriber number used to designate the mobile equipment to a destination at non-call reception registration to the resident zone network C (S4). The subscriber position registration is requested to the home network A of the subscriber number with a roaming number RON-d, and the home network A stores the RON-d of the subscriber and sends the subscriber information to the resident zone network C, and the database 43 stores the RON-d (S9). When no call reception registration is in existence for an incoming call, the destination is decided based on the RON-d.
