The present disclosure relates to a system (108) and a method (600) for barring of SMS The system (108) includes an interface unit (210) to receive the SMS from a user equipment (UE) (102). The system (108) includes an identifier unit (212) to determine a Radio Access Technology (RAT) type of the received SMS. The system (108) includes a retrieval unit (214) to retrieve information pertaining to location of the UE from a Home Subscriber Server (HSS) (420) when the RAT type is determined as a Wireless Local Area Network (WLAN) type. The system (108) includes a comparison unit (216) to compare the retrieved information associated with the UE with a barred list to determine if the retrieved location is present in the barred list. The system (108) includes a transmittal unit (218) to transmit an error code in response to determination of presence of the location in the barred list.

A first computing device may anchor a call between a remote computing device and a second, computing device tethered to the first computing device via. a local wireless tether connection. The first computing device may detect an occurrence of a. tethering termination event of the local wireless tether connection. The first computing device may, in response to detecting the occurrence of the tethering termination event, park the call at a call park server to enable the second computing device to resume the call without being tethered to the first computing device.

The present invention relates to a system (1) which enables a call to be blocked by detecting a change in the caller number, with the aim of preventing phone fraud.
