Telecommunication services apparatus and methods for addressing the problem of mobile terminated message faking
First Claim
1. A telecommunications services apparatus for use with a mobile telecommunications network, the apparatus comprising means for receiving a MAP Send Routing Information for Short Message (SRI_SM message) originating from another network and operable to forward the SRI_SM message to a home location register, means for receiving a response from the home location register to the SRI_SM message, means for temporarily storing information relating to the SRI_SM response and operable to pass said response on to a network address identified as the originating address, means for receiving a MAP Mobile Terminated Forward Short Message (MT_Fwd_SM message) from said another network and operable to correlate the MT_Fwd_SM message with a previously-sent SRI_SM response using stored information, the apparatus being operable to detect and selectively reject MT_Fwd_SM messages for which there is at least insufficient correlation between the MT_Fwd_SM message and the previously-sent SRI_SM response, and to pass other MT_Fwd_SM messages on to their respective destinations.

Abstract
A telecommunications services apparatus, in a mobile telecommunications network, comprises means (2) for receiving a MAP Send Routing Information for Short Message (SRI_SM message) originating from another network and operate to forward the SRI_SM message to a home location register (4), means for receiving a response from the home location register (4) to the SRI_SM message, means for temporarily storing information relating to the SRI_SM response and operable to pass said response on to a network address identified as the originating address, and means for receiving a MAP Mobile Terminated Forward Short Message (MT_Fwd_SM message) from the other network and operable to correlate the MT_Fwd_SM message with a previously-sent SRI_SM response using stored information. The apparatus is operable to detect and selectively reject MT_Fwd_SM messages for which there is at least insufficient correlation between the MT_Fwd_SM message and the previously-sent SRI_SM response, and to pass other MT_Fwd_SM messages on to their respective destinations. The apparatus may include means for modifying IMSI information in the SRI_SM response, which may be operable to store information relating to the modified SRI_SM response and operable to pass the modified response on to the originating address network. In that case, the correlation determination may be made between the MT_Fwd_SM message and a previously-sent modified SRI_SM response.

6. A telecommunications services method for use with a mobile telecommunications network, the method comprising receiving a MAP Send Routing Information for Short Message (SRI_SM message) originating from another network and forwarding the SRI_SM message to a home location register, receiving a response from the home location register to the SRI_SM message, temporarily storing information relating to the SRI_SM response and passing said response on to a network address identified as the originating address, receiving a MAP Mobile Terminated Forward Short Message (MT_Fwd_SM message) from said another network and correlating the MT_Fwd_SM message with a previously-sent SRI_SM response using stored information, detecting and selectively rejecting MT_Fwd_SM messages for which there is at least insufficient correlation between the MT_Fwd_SM message and the previously-sent SRI_SM response, and passing other MT_Fwd_SM messages on to their respective destinations.

11. A computer program product comprising a non-transitory computer-readable storage medium having computer-executable instructions stored thereon for implementing a telecommunications services method for use with a mobile telecommunications network, the method comprising, receiving a MAP Send Routing Information for Short Message (SRI SM message) originating from another network and forwarding the SRI SM message to a home location register, receiving a response from the home location register to the SRI_SM message, temporarily storing information relating to the SRI_SM response and passing said response on to a network address identified as the originating address, receiving a MAP Mobile Terminated Forward Short Message (MT Fwd SM message) from said another network and correlating the MT Fwd SM message with a previously-sent SRI SM response using stored information, detecting and selectively rejecting MT_Fwd_SM messages for which there is at least insufficient correlation between the MT Fwd SM message and the previously-sent SRI SM response, and passing other MT Fwd SM messages on to their respective destinations.
