Problems solved by technology

Most data card users use the same SIM card to exchange between the mobile phone and the data card according to needs. When the user puts the SIM card on the data card for use, they pay more attention to data services, because data services are In other words, it is far more convenient to operate on a PC than to perform data operations on a mobile terminal, but it is not very convenient for the SMS service.

Embodiment Construction

[0031] The main idea of ​​the technical solution of the present invention is to check each other by reading and writing the EF (Element File) file in the SIM card and the NV (Non Volatile Random Access Memory, non-volatile random access memory) in the data card, and finally determine that the SIM card is The method is used on the data card and automatically blocks the function of receiving short messages.

[0032] The present invention proposes a verification method using the EF file in the SIM card and the NV file in the data card, and reports to the network that it does not support the CS domain (Circuit Switched Domain, Circuit Switched Domain) during the network attachment process of the data card terminal. Or the MT SMS (Mobile Terminated Short Message Service) message of the PS domain (Packet Switched Domain, packet switching domain), so as to achieve the function of shielding the SMS receiving function and not bringing fees to the sender. The solution involves three asp...

Abstract

The disclosure discloses a method for shielding a short message receiving function. The method includes the following steps of: storing parameters related to short-message-receiving-function-shielding in an Element File (EF) in a Subscriber Identity Model (SIM) card; performing inter-verification by utilizing the EF in the SIM-card and a Non Volatile (NV) random access memory in a data card to determine whether the SIM-card is applied to the data card; and when the SIM-card is determined to be applied to the data card, reporting the parameters related to short-message-receiving-function-shielding to a network during the process of attaching mobile terminal to the network. Compared with the conventional art, the technical solution of the disclosure can shield the short message receiving function without generating short message fee, so as to enhance the stability of the data service to a large extent and increase the flexibility for a subscriber in selecting the service type at the terminal.

Description

technical field [0001] The invention relates to the technical field of wireless communication, and more specifically, to a method for shielding the function of receiving short messages and a data card. Background technique [0002] With the mature development and commercial popularization of 3G technology, the competition among operators is intensifying. The sales of data card terminal equipment are increasingly customized by operators, and SMS is one of the necessary and important customization requirements. Moreover, various differentiated short message customization requirements have become a general trend that many operators require for terminal software functions. [0003] Although the existing mobile communication network has services such as data, SMS, and voice, the concurrent support for these services is not perfect. When two or more services are carried out at the same time, some services are in the circuit domain. Bearing, some services are carried in the packe...
