Embodiment 1

[0043] like figure 1 As shown, the multi-SIM card multi-operator network fusion system in this embodiment includes a device terminal with an external SIM card and a built-in SIM card, and a background system wirelessly connected to the device terminal. The device terminal can be a mobile phone or a vehicle networking device.

[0044] The built-in SIM card is a patch SIM card, and the built-in SIM card has been patched on the main board when the equipment terminal leaves the factory, and it is connected with the equipment terminal as a whole. The external SIM card is an active card, which is inserted into the card slot at the end of the device by means of insertion, and can be replaced. The external SIM card and the built-in SIM card use tariff packages of different operators. In this embodiment, the external SIM card is a China Unicom card, and the built-in SIM card is a telecom card. During use, a binding relationship is established between the external SIM card, the built-...

Embodiment 2

[0063] This embodiment is the SIM card switching method of the multi-SIM card multi-operator network fusion system in embodiment 1, which specifically includes the following steps:

[0064] S1. Database update: update the network signal parameters and limited handover strategies of each operator covered by each region in the database.

[0065] Through the self-learning mechanism, during the operation process, the operator’s network signal strength and SIM card switching frequency data uploaded by the user equipment terminal are collected, and the database is updated iteratively, which specifically includes the following steps:

[0066] a. Initialize the database, and mark several data points in the area covered by the network in units of each square kilometer. Each data point records the base station in the range, the average signal strength of the base station and the limited switching strategy; after the database is initialized, each The base station and the average signal s...

Embodiment 3

[0076] The present embodiment is the recharging and charging method of the multi-SIM card multi-operator network fusion system of embodiment 1, which specifically includes the following steps:

[0077] (1) Establish a binding relationship between the built-in SIM card, the external SIM card and the device terminal. Under the dual-SIM card fusion solution, since the user may switch back and forth between the two SIM cards, the background system cannot simply assign a package to one SIM card, but needs to calculate the package on the two SIM cards. When implementing this algorithm, the background system needs to obtain the ICCID of the internal and external SIM cards from the client and store it on the server, and establish the binding relationship between the internal and external SIM cards and the device terminal according to the ICCID of the internal and external SIM cards; specifically The steps are as follows:

[0078] (1.1) The background system obtains the ICCID identifi...

Abstract

The invention discloses a multi-SIM card multi-operator network fusion system, comprising a device terminal with an external SIM card and a built-in SIM card, wherein the multi-SIM card multi-operatornetwork fusion system further comprises a background system wirelessly connected with the device terminal. The invention further discloses an SIM card switching method of the multi-SIM card multi-operator network fusion system. The method comprises the steps of: S1, database update: updating network signal parameters and limited switching strategies of operators covered by each region in a database. The invention further discloses a recharge billing method of the multi-SIM card multi-operator network fusion system, comprising the steps of : (1) establishing a binding relationship among the built-in SIM card, the external SIM card and the device terminal. According to the multi-SIM card multi-operator network fusion system disclosed by the invention, the network disconnection rate of a vehicle owner in use due to the insufficient coverage of an operator base station network is effectively reduced by using a dual SIM card switching mechanism, and the success rate of the operation of Internet of Vehicles service is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a multi-SIM card multi-operator network fusion system and a SIM card switching and charging charging method. Background technique [0002] Existing in-vehicle networking devices can usually only carry one SIM card, the common SIM cards of China Unicom and China Telecom at this stage. On-vehicle devices, the application of dual-SIM card dual-operator network integration has not yet appeared. Using a single-SIM card single-operator network on the Internet of Vehicles equipment cannot ensure that the operator has sufficient network coverage in all parts of the country. Ensure that car networking services can operate normally across the country. On mobile phones and other devices, dual-SIM mobile phones require users to purchase two SIM cards, recharge and renew separately, and users need to pay for the two SIM cards. And it is necessary to manually select which SIM card to ...
