Description

IMPROVEMENTS IN OR RELATING TO COMMUNICATION SYSTEMS

S FIELD OF THE INVENTION

The present invention relates to a communication system and method that is particularly applicable to mobile information device profile (MIDP) based platforms such as embedded systems.

BACKGROUND TO THE INVENTION

In the computing industry, particularly in fields such as wireless technology, the speed at which a technology runs through its life cycle is much quicker than elsewhere. A brand new product can become obsolete within months due to an improved technology or platform. One of the major issues with this is that products are introduced and become subsequently outdated so quickly that standardisation of the technology or particular features is not always viable.

Indeed, by the time a group of developers is ready to sit down to discuss standards, the next evolution of a product or technology is often already under development or even on sale.

Many computing devices, particularly those designed to be portable or hand-held and also those branded as "consumer electronics" intended for users with little or no computing expertise, are based around embedded systems. An embedded system is typically a special-purpose system in which the computer processing : :* 25 capabilities and software is completely encapsulated by the device it controls.

Unlike a general-purpose computer, such as a personal computer, an embedded system performs pre-defined tasks, usually with very specific requirements. Since the system is dedicated to a specific task, design engineers can optimize it, reducing the size and cost of the product. Embedded systems are often mass-produced, so the cost savings may be multiplied by millions of items.

The result of the rapid evolution of products, particularly in embedded systems, is that a software development team currently needs its staff to understand numerous system architectures, languages and processes in order to deploy a product onto multiple devices.

Whilst environments such as Java (RTM) are intended to provide a common platform independent environment from which software can be run, different implementations and standards applied to the environments make application and service provision extremely difficult and unpredictable to developers. Indeed, it is not at all uncommon for a developer to have to re-engineer his or her product or service for each platform or environment, even when they say they run Java (RTM) or a similar non-platform specific environment.

A recent development is that of MIDP, a Java (RTM) based runtime environment for mobile devices providing a platform for dynamic secure delivery of graphical networked applications to users.

Devices that are compliant with MIDP are supposed to enable vendors to develop applications that can run on multiple wireless platforms without spending intensive amounts of energy customising or reworking for each platform. MIDP is intended for use with embedded devices such as cell phones and PDAs and sits on top of a JAVA (RIM) environment.

However, whilst MIDP may solve incompatibility problems, it introduces other problems. * **.

US2004061718 (iBM) provides a method of chat messaging whereby :.* communication links are established with at least a first and a second participant *.* * for exchanging chat messages through a chat engine. A state change can be detected for the first participant, sometimes necessitating a redirection. An alternate communication channel and an alternate communication channel address can be determined from a user profile of the first participant. While maintaining the communication link with the second participant, a different communication link can be established using the alternative communication channel and the alternative communication channel address. As will be appreciated, information exchange and continuous bidirectional channel support are necessary.

US2003096614 (Paila) teaches of a method and apparatus for transmitting and accessing announcement information identifying available services. Services are provided on the network over a plurality of communication channels, at least one of which is dedicated as an all-announcement channel, which includes a service announcement for each one of the services available on the plurality of communication channels. Redirection information is also present.

US20050198203 (Tsai) provides redirection over computers operating in a systems management servers environment.

OBJECT OF THE INVENTION

The present invention seeks to provide an improved telecommunications system.

In particular, the present invention seeks to provide an infrastructure and system that is applicable to embedded systems such as wireless/mobile devices and set top boxes. It is also applicable to telecommunication media such as land lines (ordinary telephone systems/satellite technology).

STATEMENT OF THE INVENTION

According to a first aspect of the present invention, there is provided a communication system arranged to communicate with a client platform connecting to a first resource via a first communications channel, wherein the communications system is arranged to establish a discontinuous second * *, 25 communications channel with the client platform for redirecting communications, a communication transmitted by the communications system via the second * communications channel is operative to cause a client platform to connect to a *...: second resource at a redirected location different to that of the first resource. * S

Environments based on the MIDP specification are a useful advance to embedded systems and the like but unfortunately introduce a prohibition on redirection of communications. This prevents a system acting as a central hub for connections and redirecting connections to an appropriate node after some initial processing. Redirection is an extremely common practice and prohibition by MIDP reduces the appeal of using MIDP significantly. Embodime,gs of the present invention enable redirection to be used on MIDP based systems without affecting other operations and therefore address this problem whilst retaining the advantages provided by MIDP. The present invention provides self- contained security measures embedded in the application level using session-based authentication/encryption ensures maximum security unique to the invention. The session based authentication/encryption is particularly appropriate where HTTPS and Secure Socket Layer techniques are either unavailable and / or unsuitable.

Within the context of evoMng generations of mobile telecommunications systems the proposed invention is particularly suitable for 2.5 G (General Packet Radio Service -GPRS) telecommunications services and beyond. There is no requirement for maintaining a continuous multiple channel connection. In order to maintain session connectivity and redirection of the session the present invention halts the sessions to maintain high security for server side operations.

DETAILED DESCRIPTION OF THE INVENTION

There will now be described, by way of example only, the best mode contemplated by the inventor for carrying out the present invention. In the following description, numerous specific details are set out in order to provide a complete understanding to the present invention. It wilt be apparent to those skilled in the art, that the present invention may be put into practice with variations of the specific.

Figure 1 is a schematic diagram of a communications system 10 according to an embodiment of the present invention. The communication system 10 is connected to a communications network 20 and is arranged to accept connections from client platforms 30-50. The client platforms are MIDP based platforms such as mobile telephones 30, set top boxes 40 and POAs 50.

The communication system 10 is arranged to operate in a normal expected manner during a first communication session with (and initiated by) one of the client platforms 30. The client platform 30 would typically connect to the communication system 10 over a first communications channel with a request to access content from a particular resource 15 identified by a particular resource address such as: http://www.xyzserver.net/resourcei.jsp Content from the resource 15 is provided to the client platform 30 for appropriate action. In this case, the content is Java (RTM) code and would be executed by the client platform's Java environment and may result in a graphical user interface being presented to the user of the client platform 30 for interaction with the :. communication system 10. Should the client platform require access to different *s::, resources (for example due to a selection or navigation by the user at the client * *** platform), an appropriate request is sent to the communication system 10 and content is returned accordingly. ***

S

* Should the action of the client platform 30 or its user cause the communication S.....

* : system 10 to redirect the communication session (for example by telling the client S.....

* o platform to now obtain content from a resource 15' at http://www.abcserver.net/resourcei.htm), this would normally fail on MIDP based platforms due to the prohibition on redirection.

In embodiments of the present invention, this issue is addressed by the communication system 10 by using a second communication channel 60 to establish a second communication session between the client platform 30 and the redirected resource 15'. In the embodiments discussed below, the example second communicat,n channels 60 used are Short Messaging Service (SMS) messages and a satellite downlink channel, although it will be appreciated that any communications medium or system could be used.

In each case, the communication system 10 initiates the second communication session over the second communications channel 60 and communicates details of the location of the redirected resource 15' for the client platform 30 to connect to. The client platform 30 is then able to connect to the resource 15' using the location details received.

Whilst the communication network 20 and second communications channel 60 used for each of client platforms 30-50 illustrated above are the same for all dient platforms 30-50, this need not be the case. Different communication networks 20 (optionally based on different communication mediums such as wired, wireless etc) may be used by the communications system 10. Similarly, different second communications channels 60 or channel types could be used for different dient platforms or client platform types. Examples of diffenng implementations are discussed below.

:**::: Figure 2 is a schematic diagram illustrating a secure communications system : 25 according to an embodiment of the present invention.

In the illustrated embodiment, the communications system 10 operates as a portal to a secure system 100 enabling set top boxes to access an email system, S.....

* : banking facilities or the like. In the illustrated embodiment, the set top box 40 is a * 0 set top box for a satellite broadcasting system 60 and includes a first communications link 41 to a public switched telephone network (PSTN) 20 and a second communications link 42 for receiving encoded messages via the satellite broadcasting system 60.

The communications system 10 is arranged to allow the set top box 40 to connect and establish a first communications session via the PSTN 20. The communications system 10 obtains logon credentials from the set top box 40 and checks these against a local database 11. Upon authentication of the logon credentials the communications system transmits a redirection message 61 via the satellite broadcasting system 60 to the set top box 40 causing a separate application to be run at the set top box 40 which connects to the secure system 100.

The redirection message 61 includes sufficient information to enable only the set top box to access corresponding data at the secure system 100. Optionally, the set top box may include an encryption key 43 that may be required for use in combination with the redirection message to enable access to the secure system 100. In this manner, even if the redirection message was intercepted, access to the secure system 100 would not be possible without the key 43.

Figure 3 is a schematic diagram illustrating a web based gaming system according to another embodiment of the present invention.

In the illustrated embodiment, the communications system 10 operates a web based gaming system enabling mobile phones 30 to purchase lottery tickets. In the illustrated embodiment, the mobile phone 30 is able to connect to the communications system 10 via a mobile data communications network 20 (such as a 2.5G or 3G data network) and also includes an SMS dient 31 able to receive SMS messages. * *., I. S IS. S

A user is able to download a software application designed to suit most of the current available mobile phones via various routes available for electronic data S.....

* * exchange such as: direct installation at manufacture by the manufacturer of the device; download from a service provider such as mobile phone network operator download via CD, DVD or other media; or download from a web server.

On running the application on the mobile phone 30, a graphical user interface is displayed as shown in Figure 4. No logon or authentication is required to play the game or register and as such the application is not server dependent.

Once the user has made his or her selection, the application establishes a connection via communications network 20 to the communications system 10.

The user's selection is communicated to the communications system 10.

In one embodiment, connection is achieved via http and/or https communication protocols. The communication to the communications system 10 may be in the form of a "redirect command" for example: "httpilwww.mob,Wotto.co.uklredirect?to&n2,6,1 7,24,34,44&d0&W=O?p=44444444 where: * p is the mobile device's identifier (typically a phone number). The transaction is registered with this number, which will then be associated with a unique ticket number, * n is the user's parameter selection for the game (in this case lottery numbers); * t determines the game type (National Lottery, Lotto etc); and, * d & w correspond to day and week information.

The invention also consists of self-contained security measures embedded in the "*** application level using session-based authentication/encryption unique to the *S..

In order to provide a receipt of the submission, the communication system 10 :" generates an SMS message 60 which it transmits back to the mobile phone 30.

:30 The SMS message 60 includes the redirection message that, when received by the mobile phone and opened in an appropriate client application (for example the default or a custom SMS messaging client), causes the mobile phone to connect to a different (redirected) location 15' at the communication system 10 where the receipt data is stored, as is illustrated in figure 5.

As is illustrated in Figure 4, the application may enable the user to access multiple games.

For example, the SMS message 60 may include a URL as an attribute causing the mobile phone to open a isp (ava Server Page)when the SMS message is opened. The URL may be of the format: usedcore taglib:<c:import url"${requestscope. URL}/> In this manner, the URL is not altered in anyway and implies the correct response code of 200. This satisfies the MIDP based platform because it doesn't experience a context change.

A system database will preferably record all transactions, optionally notify the user of wins via their phone or set top box. In the case of notification, some form of secure Java (RIM) based application could be used to receive a bar code or other identifier allowing a use to present their phone at a lottery retailer or the like and redeem their win by presenting the identifier. The secure Java (RTM) based application would prevent the identifier being extracted, transferred, faked or used more than once.

Billing will preferably be achieved by adding a section to the user's telephone bill, and based on direct debit. Also pay as you go vouchers can be introduced.

Authentication will be based on the mobile server provider registrations. A pin *...25 system may be used to ensure only the user will be responsible for transaction. * **

On crediting the user account with the wins, one can add a slip to the first lottery phone bill, enabling a user to provide details of the users' bank accounts so their :** accounts can be credited on a win. Alternatively by producing the phone bill to * : .30 the banks along with a unique ticket no. will allow winning plays to be redeemed.

Whilst preferred client platforms are based on the Java 2 Micro Edition (J2ME), Connected Limited Device Configuration (CLDC), Connected Device Configuration (COC), MIOP technologies, it will be appreciated that other technologies such as Microsoft.Net mobile applications can also be used -indeed, MIDP and/or custom client applications are not required for operation of embodiments of the present invention. Whilst the present invention was developed to address problems with MIOP based platforms, embodiments are applicable to other platforms.

Set top boxes may optionally include a unique identifier such as a unique number issued on a card readable by the set top box. The unique identifier associates the set top box and user with a remote data record that instructs the communication system how and where to send redirection messages. The remote data record may also include data such that payments, credits etc can be applied. In the same way as the mobile phone number is submitted to the communications system 10 in the above example, the unique identifier may be used for set top boxes to identify the submission. This is cross checked at the remote data record to identify how to send the redirection message (e.g. Via satellite broadcast encrypted with a key xzyl) and its destination.

In some instances, the data record may be customised by the user to allow selection of the second channel. Preferably, the system is arranged to allow selection only of second channels that the client platform is capable of using.

The redirection message may optionally include a description of the transaction, a time/date stamp and other parameters dependent on application phone number, :... date, number of weeks to play in the case of the lottery game above. "S

* ** Dedicated applications may be developed for client platforms, not only for communicating with specific locations such as in the gaming system of Figure 3 5.

but also to enable custom handling of either messages received over the second : communications channel or communications over both the first and second :0 communications channels. For example, it would be possible to have an SMS client with web browsing capabilities (or vice versa) so that when browsing the web (first channel) redirection messages received via SMS (second channel) can be automatically used to affect the web browser and perform the redirection.
