Abstract: A short message center system and an implementation method thereof are disclosed in the present invention, to implement the short message center system with multi-network multi-plane structure. The short message center system includes a virtual short message office and at least two short message offices. Wherein the short message office includes a signaling processing module, a service processing module and SMPP AGENT module, the virtual short message office includes a forwarding module and a returning module, the forwarding module is used to, when the module of short message office is faulted, forward a message to be processed by the faulted module to a corresponding module in another short message office to be processed, the returning module is used to return a processing result to the short message office with faulted module.

Abstract: The invention provides a method for a communication system service upgrade, including: when a communication device prepares to be upgraded, an upgrade container device buffering message which currently needs to be sent to other network elements by the communication device into a sending buffer, and, when the communication device prepares to be upgraded and in an upgrade process, the upgrade container device receiving message which is transmitted to the communication device by other network elements and buffering the message into a receiving buffer; the upgrade container device sending the message in the sending buffer to destination network elements; thereby realizing an upgrade without interruption. The invention also provides an upgrade container device supporting the communication system service upgrade.
