Method for implementing roaming between networks and user short message center short message to implement roaming between networks of the user of the short message.HLR to implement roaming between networks and user short message and system for implementing roaming between networks of the user of the short message
A method for achieving short message user roaming between networks is provided in the present invention, wherein a short message center initiates a termination request to a home location register (HLR); the HLR returns the address of the termination mobile switching center (MSC) for responding to the termination request; the short message center determines whether the termination MSC address includes a particular number; when the termination MSC address includes a particular number, the short message center re-initiates a corresponding termination request to the HLR. A short message center, an HLR and a system for achieving the short message user roaming between networks are provided. The short message center inquires whether the termination MSC address returned by the HLR includes a particular number, and then special processing for roaming between networks is performed according to the particular number. Not only is the message delivery between users roaming between networks achieved effectively, but also no additional interface or network element is required, and thereby the present invention reduces the cost greatly compared with the prior art.
