Patent ID: 8660594

Claim:
A method for shielding a short message receiving function, comprising: storing parameters related to short-message-receiving-function-shielding into an Element File (EF) of a Subscriber Identity Model (SIM) card; reporting the parameters related to short-message-receiving-function-shielding to a network during network attachment carried out by a data card terminal, when, by utilizing inter-verification between the EF in the SIM card and a file of a Non Volatile Random Access Memory (NV) in a data card, determining that the SIM-card is applied to the data card; wherein after the data card is electrified and during an SIM-card initialization, a firmware program reads the EF which stores the parameters related to short-message-receiving-function-shielding from the SIM-card, and stores the parameters related to short-message-receiving-function shielding; wherein after the initialization is finished, the data card terminal carries out the network attachment, and reports the parameters related to short-message-receiving-function-shielding to the network during the network attachment; after receiving the parameters related to short-message-receiving-function-shielding, the network shields the short message receiving function of the SIM-card in a Circuit Switch (CS) domain and a Packet Switch (PS) domain, and returns an error parameter indicative of failure to a short message sending party according to a protocol when a Mobile Terminated Short Message Service (MT SMS) aiming at the subscriber exists.
