Definitions

  • the invention relates to telecommunication systems and more particularly to a method and an apparatus in a mobile communication system for identifying a sender of a mobile-terminating short message.
  • short digital data messages transferred on control and signalling channels of a system may be sent between actual signalling. These messages are generally referred to as short messages.
  • mobile communication systems are generally provided with a short message service centre.
  • the subscriber creates a short message using the keyboard of a terminal, and the terminal sends the short message on a signalling channel through a base station and a mobile switching centre to the short message service centre.
  • the short message service centre transmits the short message on signalling channels through the mobile communication network to the terminal of another subscriber or to another destination.
  • While receiving a short message a subscriber obtains on his/her display an address of an element sending the message, typically the sender's MS-ISDN number. In a sense, the number functions as a signature of the message, on the basis of which a receiver may conclude the identity of the sender. In some less advanced short message service centres, the number of the sender can be processed through an application program interface, in which case a chance to send short messages using an incorrect identity remains in the system.
  • the objects of the invention are achieved with a method according to claim 1 for identifying a sender of a short message to be received.
  • the method is characterized by identifying the sender of the short message on the basis of identification data indicating at least the sender of the short message and a sending short message service centre.
  • the invention further relates to a terminal according to claim 5 capable of receiving short messages, characterized by being arranged to form identification data of a sender indicating at least the sender of a short mes- sage and a sending short message service centre, and to show the identification data on a terminal display to be identified by the receiver.
  • the invention also relates to a terminal according to claim 6 capable of receiving short messages, characterized by being arranged to form identification data of a sender comprising at least a source address of a short mes- sage and an address of a sending short message service centre, and to compare said identification data with data stored in a memory of the terminal and to accept the short message if the identification data matches said data.
  • a sender is identified on the basis of an address of a sending short message service centre in addition to a sender address.
  • a particular short message sender operates via a particular short message service centre.
  • To falsify a number of a short message service centre without the help of an operator is virtually impossible. If the combination of the sender address and the address of the sending short message service centre is acceptable on the basis of receiver data, the re- DCver is very likely to presume that the subscriber identity is correct.
  • the subscriber may regard the data concerning the sender of the received short message as reliable and perhaps add the combination into a list of acceptable combinations. If the combination of the sender of the message and the sending short message service centre is not previously known, the subscriber can directly distinguish such cases by using the method of the invention and regard the received messages as he/she chooses.
  • the simplest form of a check of the invention can be based on the addresses of the sender and the sending short message service centre shown on the display of the mobile station, but the check can also be automatically performed.
  • the method and the system of the invention have the advantage of being easily applicable to the system, thus offering a cost-effective tool for reducing the possibilities of misuse.
  • it operates effectively enough omitting most of the potential cases of misuse, thus contributing to the reliability of the services to be carried out through an application interface.
  • the subscriber may receive messages from an increasing number of short message service centres, but has no actual chance to control the safety features of the short message service centres used.
  • the subscriber's chance to cost-effectively affect the safety level of his/her short message service is thus a considerable advantage.
  • more reliable encryption algorithms such as the ones implemented using a SIM card, can be used to protect and authenticate more important data.
  • the use of said algorithms is, however, more demanding and therefore also more expensive for the subscriber.

  • GSM Global System for Mobile Communications
  • a mobile switching centre MSC attends to switching incoming and outgoing calls. It performs tasks similar to those carried out by a centre of the public switched telephone network (PSTN). In addition, it also performs operations typical of mobile telephone traffic only, such as subscriber location man- agement, in co-operation with the subscriber registers of the network.
  • the subscriber registers in the GSM system are called a home location register HLR and a visitor location register VLR.
  • the HLR permanently stores subscriber data and information on the VLR within whose area an MS is located.
  • the visitor location register VLR in turn, temporarily stores subscriber data of a mobile station MS during the time the mobile station is in the area of the mo- bile switching centre MSC associated with the visitor location register VLR.
  • one VLR serves one mobile switching centre MSC.
  • Mobile stations MS are connected to the centre MSC by means of base station systems BSS.
  • the base station system BSS comprises base station controllers BSC and base stations BTS.
  • One base station controller BSC is used to control several base stations BTS.
  • Each base station BTS has at its disposal one or more carrier wave pairs by which it can set up a duplex radio connection with a mobile station MS roaming in its area.
  • Each carrier wave is divided into several, generally eight, TDMA time slots, or channels.
  • These GSM system channels can be divided into two categories: traffic channels (TCH) and control, or signalling channels (CCH). Speech or data can be transmitted on traffic channels, and a traffic channel is always allocated to one call only. Control or signalling channels are used for the signalling needed for system control.

  • Fixed signalling and traffic channels exist between a base station BTS, a base station controller BSC, and a mobile switching centre MSC.
  • a Broadcast Control Channel BCCH is a unidirectional control channel from a base station BTS to a mobile station MS, and is used for transmitting cell-specific information on power levels used, BCCH frequencies of adjacent cells, etc. to the mobile sta- tion.
  • a BCCH channel also includes data on synchronization and frequency correction, by means of which the mobile station is locked into the system.
  • the mobile station MS listens to base station BTS calls on a Common Control Channel CCCH, used solely to set up a signalling connection.
  • a connection is established in several stages: 1) forward- ing a call from a base station BTS to a mobile station MS 1 , 2) transmitting a random access generated by the mobile station MS as a result of the received call, or otherwise, from the mobile station to the base station BTS, and 3) allocating a Stand alone Dedicated Control Channel SDCCH to the connection.
  • Actual signalling between the base station and the mobile station MS is carried out on the SDCCH control channel. If the signalling on the SDCCH channel is call set-up signalling, the connection is transferred to a traffic channel TCH.
  • a parallel control channel SACCH (Slow Associated Control Channel) is used along with a traffic channel TCH defined for data or speech transmission between a base station BTS and a mobile station MS, or a connection-specific control channel SDCCH defined for signalling between them.
  • the parallel control channel is mainly used for transmitting measurements performed by the mobile station MS during the connection from the mobile station to the base station BTS.
  • SDCCH and SACCH control channels may be used for transmitting short digital data messages, i.e. what are known as Short Messages, between a mobile station MS and a Short Message Service Centre SMSC linked to the system.
  • the short message service centre is a centre linked to the GSM system and through which short messages are transmitted and in which the short messages can be stored for later transmission in case the receiving party is not reached.
  • Short messages sent by the short message service centre are received in a mobile switching centre acting as a short message service gateway in the GSM system.
  • the mobile switching centre asks for routing and short message data from the home location register and conveys the short message to be further delivered to the visitor location centre of the receiver.
  • short messages are data messages with a maximum length of 140 bytes.
  • a short message can be a Mobile Terminating MT transfer or a Mobile Originating MO short message transfer. Broadcasting may also be carried out through the short message service, whereby a message is sent to all mobile stations within the area of one or more cells.
