Abstract
Based on the quick constant expense computing system of memory file and real-time synchronization technique, relate to the computing system of the constant expense in the telecommunication path business.It has solved consuming time big, the problem that influences the foreground business of the existing BOSS of operator system-computed constant expense.It has set up the subscriber data Memory Mapping File and its system that is used to store subscriber information message in server memory, and utilize the OLTP characteristic in accounting data storehouse that the user profile that changes is synchronized to subscriber data Memory Mapping File and its system in real time, adopt the data read subsystem of multithreading directly from the subscriber data Memory Mapping File and its system of server system internal memory, to read subscriber information message then, and the constant expense object information formation memory file that the constant expense computing subsystem obtains is deposited in the memory file of server.The present invention has shortened the computing time of constant expense, has also avoided the influence of constant expense calculating to the foreground business, can arrive in the constant expense calculating of existing telecommunication path business.
Description
Technical field
The present invention relates to the computing system of the constant expense in the telecommunication path business.
Background technology
Constant expense is the important charging means of telecommunications operator, and for example Monthly Fee, special clothes take, and optional rate (optional bag) month function usage charges etc., telecom operators carry out marketing by collecting certain moon function usage charges usually.So calculating the every constant expense of user timely and accurately is an important indicator weighing telecom operators' charging accuracy.
Along with the expansion of each provider customer's scale and the lifting of rate complexity, the time that constant expense is calculated is more and more longer, performance consumption to the BOSS system, especially very big to the performance consumption in accounting data storehouse, cause the foreground service handling to be affected in constant expense computing interval decreased performance because of the accounting data storehouse, the processing speed in accounting data storehouse also descends greatly.In addition, along with the development of business, the expansion of userbase, constant expense is calculated the linear trend that increases that also is consuming time, and coverage enlarges, and progressively has influence on user's satisfaction.
At present, all adopt the data of database processing mode during each BOSS of operator system-computed constant expense, the performance bottleneck of database when handling data in enormous quantities determined its treatment effeciency extremely low.
Summary of the invention
In order to solve consuming time big, the problem that influences the foreground business of the existing BOSS of operator system-computed constant expense, the present invention proposes a kind of quick constant expense computing system based on memory file and real-time synchronization technique.
Quick constant expense computing system based on memory file and real-time synchronization technique of the present invention comprises:
Constant expense computing subsystem 5, the user profile and the outside cost information that are used for obtaining according to data read subsystem 4 calculate, and then obtain customer charge increment information and constant expense cumulative information;
Described quick constant expense computing system based on memory file and real-time synchronization technique also comprises:
Subscriber data Memory Mapping File and its system 2, form by a plurality of subscriber data Memory Mapping File and its mmap, each subscriber data Memory Mapping File and its mmap is made up of a plurality of subscriber information messages, described subscriber data Memory Mapping File and its system 2 is used to store subscriber data, and can be connected with accounting data storehouse 1 by real-time interface, data variation part real-time update in the accounting data storehouse 1 is arrived corresponding subscriber data Memory Mapping File and its mmap;
Constant expense is statistics sub system 6 as a result, is used for the customer charge increment information that constant expense computing subsystem 5 obtains is updated to corresponding incremental expense Memory Mapping File and its and real-time account system respectively; Also be used for the customer charge cumulative information that constant expense computing subsystem 5 obtains is updated to corresponding aggregate expense Memory Mapping File and its; Also be used for customer charge information being write database subsequent collection table at the end of month.
Described real-time account system is an existing account system in the BOSS system, is used to store the system of customer charge information.
Quick constant expense computing system based on memory file and real-time synchronization technique of the present invention, with of the prior art when constant expense is calculated, need gather the pattern of user data information in the accounting data storehouse improves, the present invention is mapped to the accounting data library information in the original system and forms subscriber data Memory Mapping File and its system in the internal memory of server system, and employing real-time synchronization technique, the data in real time that changes in the accounting data storehouse is updated to subscriber data Memory Mapping File and its mmap of the present invention, guarantee that the user data information of subscriber data Memory Mapping File and its of the present invention system is consistent with information in the accounting data storehouse, when calculating customer charge, directly from the subscriber data Memory Mapping File and its system of server system internal memory, read subscriber information message, and will calculate the constant expense object information formation memory file that obtains and deposit in the memory file of server.It is fireballing more than what search for from the accounting data storehouse, read and write data directly to read and write data from internal memory, also avoided every day owing to calculate a large amount of read-write operations of constant expense to the accounting data storehouse, reduced operating pressure to the accounting data storehouse, discharged BOSS system resource, not only improved the computational speed of constant expense, also avoided owing to calculate the influence of constant expense to the foreground business.
Through using the quick constant expense computing system based on memory file and real-time synchronization technique of the present invention, make average consuming time being reduced in 5 minutes of constant expense calculating from original 500 minutes in China Mobile Communication Group Heilongjiang Co., Ltd..
