Message processing method for signal connection controlling part in distribution type system

Abstract

The invention is an information processing method for signalling connection control part in a distributed system, dividing local reference number (LRN) into module number and in-module connection ID; as receiving connection request (CR), an information receiving module receives the CR and directly processes it; as receiving non-connection request (NCR) information, obtains LRN from the non-connection request and obtains module number from the LRN: if the module number is not its own, directly send the NCR information to the corresponding module for processing; otherwise process the NCR information; as sending CR, constructs LRN by its own module number and the connection ID obtained from the module, and fills the LRN in information and sends the information to the opposite end. The invention reduces internal inquiry information between modules of distributed system during calling, thus reducing operating load and raising information processing efficiency.

Description

technical field [0001] The present invention relates to a signaling processing method in the telecommunication field, in particular to a message processing method of a signaling connection control part (SCCP) in a distributed system. Background technique [0002] With the promotion and development of telecommunication services, users have higher and higher requirements for switch capacity. Traditional switches have gradually shifted from a single-rack, single-board or single-module hardware architecture to a multi-rack, multi-board, and multi-module hardware architecture. Each module independently hosts a set of signaling software and manages its own signaling resources, but it must work with software on other modules. [0003] The Signaling Connection Part (Signalling Connection Part) is referred to as SCCP, which strengthens the function of the message transfer part (MTP), which is equivalent to the third layer of the OSI (Open System Interconnection) reference model, and...
