Embodiment Construction

[0041] It should be noted that, in the case of no conflict, the following technical solutions and technical features can be combined with each other.

[0042] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0043] This embodiment proposes an implementation system and method for integrating NFC and SIM functions in one package. This method of integrating NFC and SIM functions can be SOC (system on chip: realize two functional modules on the same silicon chip) or MCP (multi-chip package: realize two chips in the same package), such as image 3 Shown: this figure is the concise application figure of the present invention in mobile phone, module 1. is BP (Baseband Processor, mobile phone baseband processor) in mobile phone; Module 2. is a kind of integration NFC and SIM function that the present invention proposes in a package In the new SIM card (integrated function module), ②-1 is the NFC controller, ②...

Abstract

The invention relates to the communication field, especially a communication system and method integrating NFC (Near Field Communication) and SIM. The communication system comprises a base-band processor used for processing and storing incoming signals; and an integrating function module connected to the base-band processor, provided with an NFC controller and an SIM function module, and supporting an NFC mode and / or an SIM mode. The NFC mode and the SIM mode share pins of the integrating function module to realize switching between the NFC mode and the SIM mode. The communication method comprises the steps of: S1, sending a communication request which passes through the base-band processor in the SIM mode and enters the integrating function module; S2, converting the SIM mode into the NFC mode, determining whether a first time of communication with an NFC terminal, executing S3 if yes, and executing step 4 if no; S3, dynamically configuring an inner configuration circuit to couple with the external capacitor in an antenna coupling module, and executing S4; and S4, establishing correct and / or stable communication with the NFC terminal.

Description

technical field [0001] The invention relates to the communication field, in particular to a communication system and method integrating NFC and SIM. Background technique [0002] The current mobile payment business can be divided into off-site non-real-time payment and on-site real-time payment according to the space and time characteristics of payment. Off-site non-real-time payment is a commonly used payment method at present. This method generally initiates transaction requests through SMS. From the perspective of payment speed, there is an obvious time delay. It takes a few seconds when it is fast, and even minutes when it is slow. Mobile shopping and mobile banking currently carried out in China are all such off-site non-real-time payments. Off-site non-real-time payment, due to its obvious time delay, has been unable to meet the application fields of bus tickets, rail transit, taxi fares and other urban one-cards. In this case, on-site real-time payment transactions ...
