Definitions

• the present invention relates to a method of transmission of short messages in a mobile telecommunications system.
• SMS Short Message Service
• SMS-CB SMS Cell Broadcast
• Document 20 relates to broadcasting of emergency or SOS-information by means of FM-transmitters .
• the above mentioned aim is achieved by a method for transmission of short messages in a mobile telecommunications system, at which said short messages are speech messages which are transferred by means of a packet switched radio carrier such as GPRS.
• An advantage of the invention is that it can be utilised for general traffic information when a driver is busy driving a car.
• One further advantage is that a voice message can be stored directly in the telephone, which results in that a subscriber need not call his/her own voice mailbox and load the network unnecessarily.
• GPRS General Packet Radio Service
• GPRS General Packet Radio Service
• GPRS is a cost efficient service in the sense that a GPRS-mobile utilises the radio channel only when it has data to transmit or receive.
• the advantage of GPRS is short setting-up time compared with today's voice traffic, high data rate, and more efficient utilisation of radio resources.
• GPRS further can be used as "best effort" -service, which means that one only utilises free capacity. GPRS probably will be cheaper than a circuit switched service.
• GPRS is a packet switched service which initially will offer non-real-time services such as Internet-services. On the other hand, GPRS will not offer ordinary telephony.
• the difference between real time services and non-real-time services is the Delay-demand. Delay is a measure of how long time it will take to transmit bit data from a user to another. Telephony is a real-time service which has a delay demand of a few milliseconds, whereas Internet-services have lower delay-demands.
• GPRS is not intended to be used as carrier of speech in real-time.
• GPRS can transfer non-real- time speech in order to satisfy the need for future services which are adapted to GPRS.
• GPRS PTP Point-to-Point : Voice message to one single subscriber: For instance voice mailbox.
• GPRS PTM-M Point-to-Multipoint Multicast
• GPRS PTM-G Point-to-Multipoint Group
• Voice message to a group of subscribers, possibly within a geographical area, but the communication can be two-way: For instance communication within a taxi firm.
• the present invention consequently presents a new carrier service or application which shall transfer short speech messages over a packet switched carrier, for instance GPRS.
• the service can be either a telecommunications service, i.e. all necessary functionality is in the mobile terminal, or an application connected to the mobile terminal which uses for instance GPRS as carrier of the voice information.
• the service is called SVM (Short Voice Message) .
• SVM The principle of SVM is very simple. It amount to that the speech message is speech encoded, in an application in the network or in another mobile terminal, and is transmitted to the receiver via GPRS. When the message has been received, the message can be decoded and be read/played; either directly in the GPRS-mobile, or in an application outside. SVM opens new opportunities to quite new services, and refines existing services. SVM requires that the mobile has a memory in it to receive and store speech messages. The size of the speech message is of the order of a few seconds, and shall be possible to be hold on the SIM-cards of tomorrow, or on a chip card in future terminals.
• SMS-service Short Message Service
• PTP Point-to-Point
• PTM Point to Multipoint
• SMS is used to transmit text messages.
• Text messages can be transmitted from one subscriber to another, as a common short text message, or from the network to a subscriber to inform about, for instance, new messages on his/her mobile mail box or "fax box” etc.
• SMS is a non-real-time service. It is transmitted on the signalling channel and has a comparatively low delay demand.
• GPRS it will be possible to transmit SMS on common GPRS traffic channels.
• SVM will function roughly in the same way as SMS, but with speech instead of text .
• the advantage of SVM are plenty and can be summarised by saying that speech in some connections is better than text .
• Mobile answer is a telecommunications service which today is used in GSM and which can be modified to adapt to GPRS.
• a central database in the network, where the messages of all mobile answers are stored.
• an SMS is transmitted to the mobile which calls the central database in order to listen to the recorded message.
• All recorded messages are stored in the network, and each time one needs to listen, or listen again, to a message, a connection is established and a radio resource is used. To listen, and listen again, to all ones mobile answer messages loads the network unnecessarily.
• SVM can be used as carrier to such a service.
• One more PTM GPRS-service can be that one transmits advertisements via SVM to all mobiles which are within a specific area, or to a specific target group.
• SVM also gives means for new services, new products and new user groups.
• One example can be a new "minicall" - terminal and a new "minicall” service.
• a conceivable minicall GPRS-terminal with a memory and a loudspeaker can be a cheap alternative.
• a new "minicall" -service adapted to the minicall GPRS-terminal can be that one transmits an SVM-message.
• a conceivable user group for such a service can be children or handicapped who neither can read nor use a complicated mobile terminal.
• the advantage of such a service, compared with today's minicall is that one will have international coverage, and a confirmation from the receiver at succeeded reception, when it uses GPRS as carrier.
• the invention is primarily intended to be used for broadcast of voice information for, for instance, traffic information and advertising.
• the service in addition can be used to create a distinctive image for Telia as operator.
• a short voice message can be transmitted to one or a lot of users; the carrier utilises GPRS PTP, GPRS PTM, or other similar carrier service; also non-packet-switched carriers can be used, but will reduce the advantages of the service; the voice messages are speech encoded and are transmitted over a packet switched radio carrier; voice messages are decoded and played, either directly in the mobile terminal, or in an application outside, i.e.
• the SVM-application can be integrated in the mobile terminal, or outside the terminal in a device connected to said mobile terminal;
• the speech encoder can be a GSM's speech encoder, because this decoding function already exists in the GSM-terminal (provided that the terminal does not only support GPRS) ; also other speech encoders are conceivable, especially in the case where the SVM-application is located outside the mobile terminal;
• a voice mailbox transmits voice messages directly to the user via SVM, where the message at optional time can be listened to, and saved, without the user needing to "call" mobile answer; traffic information can be transmitted via SVM so that a driver of a car need not read SMS-text while driving;
• the application SVM can be implemented integrated in future data communications solutions for cars.
