Definitions

  • the present invention relates to new services for mobile phone users and more specifically the Multimedia Messaging Service (hereafter also abbreviated to MMS) and respective delivery method for messages exchanged between different operators.
  • MMS Multimedia Messaging Service
  • SMS Short Message Service
  • the text message system is integrated into the mobile phone network thanks to said network's effective use of the addressing and routing system.
  • the short message structure cannot be used to send multimedia messages since this only allows ASCII text messages of very limited size to be sent.
  • the new generation of multimedia services supersedes the typical features and limitations of conventional messaging, with the new MMS phones offering the possibility of sending a multimedia message whose size can reach as much as several hundred kilobytes.
  • the current MMS is based on the principle of sending the message to both mobile phone numbers and e-mail addresses; in particular, a special server inserted in the operator network (known as Multimedia Messaging Service Centre, or, shortly, MMS-C) arranges for suitable transcoding of the message sent so that both e-mail server and mobile phone user can understand it.
  • a special server inserted in the operator network known as Multimedia Messaging Service Centre, or, shortly, MMS-C
  • the MMS can be considered a new type of message defined as being "borderline" between Internet and telecommunications, since on one side users are connected to the mobile phone network and on the other side servers are interconnected to Internet.
  • SMIL Synchronized Multimedia Integration Language
  • the latter will send the push notification to its recipient user; f) the recipient can then decide whether or not to download immediately the message that has been notified to him; g) should the user decide to read the MMS message sent to him, the mobile phone establishes a WAP connection with the MMS-C and the downloading of the MMS message begins; h) finally, the mobile phone shows to the user the content of the MMS message received: i.e. a suitable combination of pictures, text and audio.
  • MMS interworking i.e. the exchange of MMS messages between different mobile phone operators.
  • MMS interworking works in the manner illustrated in the block diagram of Fig. 1 , in which, for the sake of clarity, the message route is shown with a bold line, the connection route with a normal-sized line and the Push signaling route with a broken line:
  • the service centre MMS-C 5' takes the message content and acquires the recipient's identifier, defining said recipient as a user not managed by the network operator from which the message originates, anyway identifying the operator of the network of which the recipient is a subscriber;
  • SMTP Simple Mail Transfer Protocol
  • the latter arranges for actual delivery of the message, firstly by sending a Push signal (broken line 4'-6'-9 in figure 1) to the recipient's terminal 9, usually by means of a Push Proxy Gateway 4' and a SMS-C 6'.
  • This Push signal normally transferred via a suitably coded SMS, is delivered to the recipient's terminal 9, carrying on-board a MMS client capable of recognizing that particular SMS as a Push signal. Therefore, the terminal is able to open this SMS, read the address of the service centre that has contacted it, opens a WAP session through a WAP Gateway 3" towards the MMS-C 5", by exploiting a GPRS or GSM apparatus 2", and thus downloads the message.
  • MMS interworking model is based on a specific assumption: a user mobile terminal is obliged to interwork solely with the service centre MMS-C of its own network operator.
  • An immediate consequence is that MMS transmission between subscribers of different mobile operators requires interaction between the service centers of such operators.
  • SMS-C Session Management Centre
  • the service centre address profile in the mobile terminal has the sole aim of sending messages and not that of sending acknowledgements.
  • the recipient mobile terminal employs the services of the same signaling network in order to send automatic acknowledgements to the originating SMS-Cs.
  • the MMS is mainly a "Push/Pull/Ack" type of architecture in which the service centre MMS-C sends notification of the message arrival to the recipient mobile terminal (Push), the terminal downloads the message (Pull) and then confirms successful download completion to its MMS-C (Ack) that may be different to the originating one.
  • the network architecture set out in Fig. 1 and the respective solution need considerable commitment in solving mobile number portability problems. Indeed, prior to the introduction of this service it was fairly simple to identify the network operator and the respective service centre of the recipient of the MMS message through a direct analysis of the MSISDN (Mobile Station ISDN Number) of the recipient. Following fairly widespread activation of the mobile number portability service amongst many operators, in order to be certain of the recipient network operator it is necessary to check whether there has been a previous transfer of the recipient's MSISDN number between network operators. This check must be carried out historically in order to include every single number portability transfer ever made.
  • MSISDN Mobile Station ISDN Number
  • MMS message addressed to the MSISDN number of another operator is in fact routed through the latter via SMTP. Indeed, once the message has reached the sender's MMS-C server 5', the latter has to route the message to the recipient's service centre 5" and obtain its domain, and therefore the respective IP address to be contacted.
  • the MMS message is originally addressed to the recipient's MSISDN number, but this provides no details whatsoever regarding the recipient's MMS-C server. For this reason, rules need to be established in order to provide a relation between the recipient SMTP server addresses and the recipient MSISDN number.
  • the MMS-C appears as an IP (Internet Protocol) address and the front end that replies to the IP address in question is actually an e-mail server that is accessed via a domain.
  • IP Internet Protocol
  • e-mail server that is accessed via a domain.
  • DNS Domain Name Server
  • a particular object of this invention is to provide a method for routing and delivering MMS messages between subscribers of different mobile phone network operators that can exclude changes of protocol and format of the original message and any addressing via DNS.
  • a further particular object of the invention is to provide a method for routing and delivering MMS messages between subscribers of different mobile phone network operators in which all number portability and addressing problems regarding a recipient who has changed operator are resolved automatically.
  • a further particular object of the invention is to provide a method for routing and delivering MMS messages between subscribers of different mobile phone network operators that uses standard telecommunications network protocols and equipment in order to provide a solution that can be implemented immediately and readily maintained.
  • the Applicant has found that these objects can be achieved by providing a method in which a MMS message addressed to a recipient belonging to the network of another network operator is stored only in the MMS-C of the originating operator.
  • a notification signal is sent to the recipient, including the address of the MMS-C in which the MMS message is stored.
  • the recipient is then allowed to download the MMS message through a gateway provided by its network operator, which is enabled to access the MMS-C in which the MMS message is stored.
  • the invention relates to a method of delivery of MMS messages according to claim 1.
  • Preferred versions of the method of the invention are disclosed in claims 2 to 8.
  • the invention relates to a service center, particularly a MMS-C, according to claim 9. Preferred embodiments of the service center of the invention are disclosed in claims 10 and 11.
  • the invention relates to a mobile network, including a service center, as disclosed in claim 12. Preferred embodiments of the mobile network of the invention are disclosed in claims 13 to 16.
  • FIG. 1 is a schematic diagram of a known network architecture handling MMS interworking between service centers belonging to different network operators;
  • FIG. 2 is a schematic diagram of an exemplary network architecture according to the invention.
  • the new architecture according to the present invention offers a reduction in the complexity of the interworking method, and at the same time allows optimum interaction in the routing and delivery of multimedia messages between users served by different operators.
  • each message is forwarded directly by the originating service centre 5 to the recipient mobile terminal 9, thus shortening the chain of events and functions needed for the delivery, and reducing the complexity of the entire procedure.
  • a MMS message addressed to a recipient managed by an operator B is delivered as usual to the service centre MMS-C 5 of the originating network operator A.
  • the notification (Push) signal 16 to the recipient is sent directly by operator A.
  • the same originating network operator A makes the stored MMS message available to the recipient terminal (9) for downloading, from its MMS-C 5.
  • the notification 16 may be for example a short message addressed to the recipient user managed by another operator B. In such way, the network operator
  • SMS interworking procedures that offer the possibility of sending and receiving short messages directly from the operator network A without having to pass through the SMS-C of the operator B managing the recipient user of the short message.
  • short messages does not provide for communication between the SMS-C of the operator to which the originating user belongs and the SMS-C of the recipient operator.
  • the network operator A In order to allow the downloading of the MMS message by the recipient 9, the network operator A must allow access to its service centre 5 by the WAP Gateway 3" of the other operator B. This can be set for the sole purpose of retrieving the message and not for other functions.
  • the delivery of the MMS message takes place in a direct manner, with no need of an actual transmission of the message by the originating service centre to the recipient service centre, only requiring a series of signaling and connection requests.
  • MMS-C access management can be configured in order to allow expected download transactions only, with no other actions permitted.
  • a WSP-HTTP (Wireless Session Protocol - Hyper Text Transfer Protocol) type connection 10 (handled by a WAP Gateway 3' through a GSM or GPRS apparatus 2) is established with the MMS-C 5 of the originating network operator A, to which the MMS message is subsequently transferred.
  • Service centre 5 arranges to activate 11 the Push Proxy Gateway 4" to send a Push signal 16, via SMS-C 6", in order to notify terminal 9 as to the possibility of downloading a new MMS.
  • the latter establishes a connection 12 with its WAP Gateway 3", via a GSM or GPRS apparatus, and from here an HTTP connection 14 with the service centre 5 of the originating network operator A.
  • a fundamental advantage of this invention is that the recipient terminal connects directly to the other network operator service center in order to retrieve the incoming message. Basically, even if the user receiving the message has its access infrastructures and WAP Gateway (3"), provided by his own operator B, as regards the service centre, he. will go and download the message from the originating network operator with whom the sender is registered. This advantageously avoids the transfer of the message from one operator to another.
  • HTTP protocol is utilized, as was also the case in the previous MMS interworking protocol.
  • HTTP protocol is used, whereas the previous method called for an initial conversion HTTP -> SMTP and subsequent reconversion SMTP --> HTTP, along with the respective format conversions of the message in transit.
  • the message no longer requires format and protocol changes during transmission. It is also worth stressing the advantage of being able to avoid routines in SMTP, that is one of the least secure protocols on the Internet and responsible for problems of spamming, sender authentication, etc., etc.
  • the solution employs SMS interworking methods, with the originating service centre 5 taking charge of the message and arranging for delivery to the recipient terminal 9 without calling for any dialogue with the service center of the other operator.
  • the MMS message is stored with the originating operator only, without the need for dialogue or forwarding of the message to the other MMS-C.
  • the address from which to retrieve the message may be contained in the Push notification signal 16 informing the recipient 9 of the availability of a new MMS.
  • the originating operator itself that sends the Push signal 16 and therefore associates the specific address of its MMS-C 5 to such communication. Therefore, a possible change of address of the MMS-C has no effect on the MMS transmission and delivery procedure and, mainly, does not impose the task of updating resident dedicated databases with each service centre.
  • it is the network operator of the originating message that performs the send of the Push message and defines IP addresses as part of the Push signal, thus producing a radically simplified addressing procedure.
  • the MMS interworking method enables updated releases to be handled by the user's own MMS-C without affecting the MMS-Cs of other operators. Indeed, since it is no longer necessary for the service centre of one operator to communicate with the service centers of other operators, in the event of release changes at the MMS-C of the sender, these would be introduced with transparency and flexibility in the MMS transmission and delivery procedure without any repercussions on the remaining components of the network architecture.
  • the invention offers additional benefits in simplifying management of Delivery Reports, i.e. those messages that notify the sender regarding the success or failure in delivering the original message.
  • the Delivery Report enables the sender to be informed by the network as to if and when the message was delivered to the recipient.
  • the mobile terminal receiving the message sends a "message received" acknowledgement to its network operator (terminating or recipient). Then, the recipient's network operator connects to the service centre of the sender's network operator in order to inform that message has (or has not) been delivered to the recipient. In turn, the originating operator has to contact its client and inform regarding message delivery success or failure.
  • the network architecture presented allows much simpler handling of this service. Indeed, in the solution according to the present invention the message is sent to the recipient terminal by the originating operator, therefore the latter can directly ascertain if and when the recipient user has downloaded the MMS, and notify the sender accordingly.
  • acknowledges sent from the recipient mobile terminal continue to be managed by the recipient's MMS-C, as in the traditional delivery report methods, since many current mobile terminals are configured to send acknowledgements only to its own MMS-C.
  • the new generation of mobile terminals with MMS will be able to address acknowledgements directly to the MMS-C of the originating operator.
