Definitions

• the present invention relates to a mobile communication system and in particular to a system for forwarding SMS messages to a predefined subscriber in a mobile communication system.
• GSM Global System for Mobile Communication
• call forwarding is well defined.
• supplementary service which can modify or supplement a basic telecommunication service defined for SMS-forwarding.
• SMS forwarding is a service by which if a subscriber B has activated forwarding for SMS to subscriber C, when subscriber A sends a short message to Subscriber B that short message will be delivered to subscriber C.
• the present invention relates to a method of unconditional forwarding of Short Messages (SMS) to a predefined number registered by the end subscriber using an Intelligent Network (IN) based solution without modifying the existing GSM (Global System for Mobile communication) architecture or any existing protocol stack.
• SMS Short Messages
• I Intelligent Network
• the present invention introduces a proxy-HLR (Home Location Register), which is an IN based service with a Mobile Application Protocol (MAP) interface between Short Messaging Service Centre (SMSC) and Home Location Register (HLR).
• MAP Mobile Application Protocol
• SMSC Short Messaging Service Centre
• HLR Home Location Register
• the Proxy- HLR which interrogates with another IN (Intelligent Network) based service called the IN FORWARDING SERVICE responsible for managing forwarding details of the subscribers to retrieve the forwarded number, if any, registered by the subscriber.
• IN Intelligent Network
• the routing information request message "SendRoutinglnfoForShortMsg" sent from the SMSC (Short Messaging Service Centre) to the HLR (Home Location Register) of original recipient is intercepted by the proxy-HLR (Home Location Register).
• the proxy-HLR determines the forwarded number by interrogating with the IN-FORWARDING SERVICE and routes the "SendRoutinglnfoForShortMsg" to HLR (Home Location Register) of new recipient corresponding to the forwarded number.
• the invention proposes a method for forwarding message to a predefined subscriber number in a mobile communication network, such messages being originally sent from a transmitting terminal to a receiving terminal, said receiving terminal being configured in such a manner that received messages be forwarded to a forward terminal identified by said predefined subscriber number, the transmitting terminal being connected to a message service centre and a home location register in said mobile communication network, the method comprising the steps of :
• Figure 1 illustrates the structure of SMS-MT (Short Messaging Service - Mobile Terminating) and the transfer of information
• Figure 2 illustrates the structure of SMS-MT (Short Messaging Service - Mobile Terminating) with proxy-HLR (Home Location Register). It depicts the interrogation between the proxy-HLR (Home Location Register) and the IN (Intelligent Network) - service.
• the present invention relates to a system for forwarding SMS message to a predefined subscriber in a mobile communication system.
• Figure 1 illustrates the process involved in sending SMS from one mobile subscriber to another in a GSM network.
• the message to be sent is submitted to the
• SMS-GMSC Gateway MSC for Short Message Service
• the SMS-GMSC is a function of an MSC (Mobile Switching Centre) capable of
• VMSC Visited Mobile Switching Centre
• VMSC is the MSC that is serving a mobile in the VPLMN (Visited Public Land Mobile Network).
• the SMS-GMSC forwards the message to the MSC.
• the MSC interacts with the VLR (Visiting Location Register) to pass the message to the destination MS (Mobile Station).
• VLR Visit Location Register
• MS Mobile Station
• a delivery report is sent back to the SMS-GMSC, it is forwarded to the SMS source location as status report.
• the invention provides a method for forwarding of short messages to a predefined subscriber number in a mobile communication network by intercepting the routing information for the message from the SMS-GMSC to the HLR with the help of a proxy-HLR.
• a proxy-HLR is an IN based service having interfaces with SMSC, HLR and IN_FORWARDING_SERVICE with the help of MAP and TCP/IP protocols.
• the new routing information obtained is sent to the New HLR which is the conventional HLR It is referred to as "New" as this HLR corresponds to the final recipient or the forwarded number if it exists else it is the original number.
• the proxy- HLR interrogates with the SMSC and HLR using MAP protocol. It interrogates with the INJFORWARDING SERVICE using Implementation dependent TCP/IP interface.
• the IN Intelligent Network
• the IN is a network-architecture for both fixed and mobile telecommunication networks. It allows operators to differentiate themselves by providing value added service in addition to the standard telecom services such as
• GSM services on mobile phones can also be regarded as an overlay on the core network.
• an IN-service is introduced before the HLR, which will act as a proxy-HLR for sending the "SendRoutinglnfoForShortMsg" information.
• the SMS-GMSC interacts with the proxy-HLR using the MAP protocol.
• the Proxy-HLR obtains the forwarding number by interrogating with the IN-FORWARDING SERVICE (3) using an implementation dependent (TCP/IP or any other interface) protocol if the SMS-forwarding service is activated or else the original destination number is returned.
• the proxy-HLR service then sends the "SendRoutinglnfoForShortMsg" to the HLR (new HLR - HLR of forwarded party) (4) corresponding to the number provided by the IN-service.
• the HLR responds to the proxy-HLR by sending "SendRoutinglnfoForShortMsgAck” (5) and the MSC (Mobile Switching Centre) location and IMSI (International Mobile Subscriber Identity) of the new number.
• the proxy-HLR returns the MSC location and IMSI of the forwarded number received to the SMSC via "SendRoutinglnfoForShortMsgAck" (6) .
• the IN FORWARDING SERVICE is an IN based service which manages the forwarded numbers registered by mobile subscriber.
• the mobile subscriber registers the number with this service via Interactive Voice Response (IVR) menu or by calling customer care.
• IVR Interactive Voice Response
• proxy-HLR service this service returns forwarded number if a forwarded is registered for the mobile number received in request if no forward number is registered.
