摘要:
A mobile switching system distributes location registration and mobile subscriber's outgoing call using a plurality of managed intelligence nodes (MINs) having a call server function. Upon receipt of a location registration or outgoing call request from a subscriber, a Mobile Switching Center (MSC) transmits a location registration or outgoing call request message to a corresponding one of the managed intelligence nodes. Upon receipt of the location registration or outgoing call request message, the corresponding managed intelligence node reads a mobile identification of a calling party and searches the mobile identification for a target managed intelligence node address. When the target managed intelligence node address is searched, the managed intelligence node determines whether a target prefix is a converted prefix having a target managed intelligence node prefix head digit, and immediately performs a location registration or outgoing call process, when the target prefix is the converted prefix.
摘要:
An electronic switching system having a plurality of processors connected to an internal switching network in a chain structure of a linked list form and a maintenance processor for checking status of each individual processor connected to the internal switching network. The status of the processors is checked through a mutual status checking process between unit processors, and if any processor contains any abnormality, such abnormal status of the processor is notified to the maintenance processor.
摘要:
The present invention relates to a method of controlling a message overload in a program of an electronic switching system having a large capacity controlled by a plurality of processors, and more particularly, to a method of controlling a message overload before a resource is requested to an operating program by the program receiving a plurality of messages. The method receives a function request message after setting a counting value for receiving a message, increases a message counter by one every time the function request message is received and then obtains a counted value by the message counter, compares the counted value with a designated threshold value, performs a corresponding specific function to thereby carry out an added job when the counted value is equal to or less than the designated threshold value, and notifies a processor which requested the specific function of a job result, and informing the corresponding processor which requested the specific function of a process impossibility when the counted value is larger than the designated threshold value, thereby generating an alarm indicating an overload state.
