The invention relates to a shared data center used in a telecommunication industry billing system. The shared data center comprises a shared data center server and a shared data center client, wherein the shared data center server is provided with a shared memory space capable of being dynamically expanded and used for storing shared data, the shared data can be loaded from a database in the shared memory space, the loaded shared data are organized in the shared memory space according to a specified data structure, the shared data in the shared memory space are automatically updated according to the change, and the read-write security of the shared memory space is ensured by using a read-write lock; and the shared data center client provides an application program interface for calling an application program of a visitor, the shared memory space is mapped into the memory space of the application program, and the application program searches the shared data from the memory space thereof according to the specified data structure. According to the data characteristics of the telecommunication industry, the invention optimizes storage mode and search algorithm so as to reduce memory consumption at the same time of meeting efficient query.

The invention discloses an electricity bill settlement system in which a charging pile does not directly exchange data with a public communication network, including a charging pile, mobile phone payment software, and mobile phone management software. The charging pile includes a charging module, a display screen, a communication module, and a control module. The charging pile of the present invention does not directly exchange data with the public communication network. In the case of network interruption, the charging pile can interact with the public network through the mobile phone payment software and mobile phone management software, and communicate with the public network through the infrared scanner. The displayed QR code or barcode communicates with the charging pile, enabling two-way secure communication, high multi-service speed, and low construction and maintenance costs, which greatly alleviates the restriction of network interruption on charging pile settlement and improves the utilization rate of charging piles.

The invention discloses a dual-microcomputer switching method in a charging system and relevant equipment and system. The dual-microcomputer switching method comprises the steps of: receiving a dual-microcomputer switching starting message sent by a charging network element before switching; after receiving the dual-microcomputer switching starting message, caching a received charging request message sent by a charging request party; receiving a dual-microcomputer switching success message sent by the charging network element before switching; and after receiving the dual-microcomputer switching success message, sending the cached charging request message to the switched charging network element, and carrying out charging treatment by the switched charging network element according to the charging request message. According to the invention, the problem of message loss in a dual-microcomputer switching process can be solved on the premise of guaranteeing the original performance of the charging system.

The invention discloses a virtual network adopting a roaming access way based on mobile communication. The virtual network comprises mobile phone networks (1) and an authentication and accounting system (2) for authenticating the identities of user mobile phones (3), wherein the mobile phones (3) are provided with SIM cards belonging to the virtual network identity; the mobile phone networks (1) provide roaming access for mobile phones (3) of the virtual network, and perform authentication on accessed mobile phones (3) through the authentication and accounting system (2); and the authentication and accounting system (2) records the call volumes and data usage of the mobile phones (3) in the mobile phone network (1) through the mobile phone network (1), and charge the users according to thecall volumes and data usage. Through adoption of the virtual network, the service coverage can be expanded through access to different networks in a roaming way; the cost on repeated laying of base stations is lowered greatly through sharing of the base stations; and up to two thirds of base stations can be saved.
