Subsection inheriting method of service unification between isomerism IC card systems

Abstract

The invention discloses a subsection inheriting method of service unification between isomerism IC card systems, and belongs to the technical field of information processing. According the thoughts of service unification and subsection centralized control, a father and son control transmitting calling mode is mainly adopted in the subsection inheriting method, read-write card modules of the legacy systems are inherited in a subsection mode, finally new and old card service process jointed handling is realized, and the aim of original service jointing when old systems are replaced by new systems is achieved. According to the method, the simple integration method of service handling between like products of different manufacturers is realized, only the read-write card modules of the legacy systems need to be extracted for repacking, then legacy services of the old systems can be rapidly fused into the service process of a new product, secondary technological development risks between the different isomerism systems are avoided, various original services can be continued without risks, the rollout time of the new product is greatly shortened, and meanwhile service guarantees for service smooth transition are provided.

Description

technical field [0001] The invention relates to a segment inheritance method for uniform business among heterogeneous IC card systems, and belongs to the technical field of information processing. Background technique [0002] With the rapid economic and social development and the acceleration of the urban one-card process, the construction concepts of "one card for multiple uses" and "multi-card integration" have been widely used in the construction of various cities. However, due to historical reasons, the current level of citizen card construction in cities across the country is different, and the replacement cycle of newly issued CPU smart cards to the existing M1 cards is very long, especially in cities with a certain scale of one-card use, the old cards have a large stock and can be replaced directly. The original IT support system had a long working cycle and faced the following problems: First, the old cards had many functions, and the redevelopment of new read-write...

Problems solved by technology

However, due to historical reasons, cities across the country currently have different levels of construction of citizen cards. The new CPU smart card has a very long replacement cycle for existing M1 cards. Especially in cities with a certain scale of all-in-one cards, the stock of old cards is large and they can be replaced directly. The original IT support system has a long working cycle and high risks, and faces the following problems: First, the old card has many functions, and the re-development of a new card reader control takes a long time, especially the lack of objective conditions for testing the old card, and the actual investment is uncontrollable; All kinds of old cards have complex internal structures, and the historical card issuance information and conditions are unknown, so it is difficult to guarantee the actual effect of the new system directly taking over the service, and the upgrade process of abolishing the old system is difficult to copy and promote; The transition mode of the old systems running independently cannot improve the continuous service experience of the original cardholders

[0003] In the past, various cities directly adopted the method of stopping or reducing the original card service system due to no card issuance or a small number of card issuances, and the workload was relatively small. Some IT support system platforms are complex, and the implementation methods of card reading and writing controls, encryption machine calls and service methods are extremely inconsistent

Every time a new system is introduced, there will be a period of stagnation or turbulence in the service, mainly because it is difficult for new construction entrants to obtain accurate technical descriptions of the card structure and historical card issuance

In the face of this situation, the traditional operation process usually adopts the rough method of overthrowing and rebuilding and splitting the boundaries of the old and new systems, resulting in the complete suspension of the old card services in stock and consuming a lot of development cycle and development costs. The characteristic of IC cards is the testing time Changhe’s on-site environment is changing, and it is almost impossible to re-test the old cards in the history, so it has an impact on the normal use of existing old card users
