Description

BACKGROUND

The present invention relates generally to a method and apparatus for exchanging information in a communication system. More specifically, the invention relates to a communication system, which connects to a private or public data communication network and to a public or private telecommunication network.

The present evolution of data-communication is such that more and more users gain access to the Internet worldwide. Internet has become both a source of knowledge but also a market place for business, and it is attracting more and more users. Currently there is a high pressure on the data-communications industry to provide solutions that allow everyone to gain access to Internet. Broadband solutions are continuously developed and both local as well as national access networks are planned and launched. The presently most common method of modem access through the telecommunications network (e.g., the Public Switched Telecommunication Network, PSTN provider) is being replaced by other ways of access with a possibility to higher data rates, e.g., through electric power and cable TV providers.

At the same time, the telecommunications industry is struggling another battle; that of providing mobility to each and every user. Traditionally, telecommunication has been focused on voice communication. With the increase of data communication however, other demands are arising (e.g., higher data rate transfer), but also new possibilities. Evolutions of mobile systems are presently in a period when more and more packet-based systems will be deployed. Packet switched systems have, in contrast to circuit switched systems, certain advantages when it comes to transfer of data-communication. In a packet switched system, a user is only utilizing a transmission resource when system control signaling or user information is transmitted. In a circuit switched system, a user is allocated a transmission resource continuously, even though no current transfer is active. Circuit switched systems have some obvious advantages in real-time voice communication, since it is difficult to predict the communication. For data-communication, it is not as important to predict the transmission resources required, since the demands on delay and delay variations are not as crucial to the communication quality as for voice. It is therefore possible to allow more users onto the transmission resources by allowing usage thereof only when there is something to transmit and leave the channel available for additional users otherwise.

One such system is the packet data evolution of the mobile communication system pursuant to the ETSI GSM specification, called General Packet Radio Service (GPRS). With GPRS, higher bit rates and more users may be allowed than what is possible today, when data communication is deployed on a circuit switched channel. GPRS is a step towards mobility for data communication users, in contrast to GSM, which is optimized for mobility for "traditional" telecommunication users, i.e., real-time voice communication users.

The data-communication run over the telecommunications networks today is usually initiated by an access to an Internet-or a mail server. A user logs on to a distant server and accesses the data-communications network through e.g., modem pools. The user dials up the modem pool and is therefore connected to a server, from which access can be made to both local as well as global networks. Browsers like e.g., Microsoft Explorer or Netscape Navigator are used to navigate on the Internet and switch between Internet pages or addresses. Users and institutions usually design their own data objects, or homepages, on an internal or external network that provides personal information or any other kind of information. Once connected to the data network a user may access these data objects by entering the correct address. The address is often selected by combining a node name in the network (e.g. server name) and an arbitrary text-string. Typically, it is not trivial to find a desired data object, since the text strings and server names are not obvious.

Addressing in a telecommunications network, e.g., when engaging in a voice communication is usually performed by entering a telephone number on a User Equipment (UE), like a mobile telephone. A telephone number is a, world-wide, unique addressing string. A calling party (A-party) dials the addressing string (B-number) to the called party (B-party). Dependent on what type of network the A-party is a subscriber on, the call request is routed through one or several public telecommunication networks to the correct addressee and the communication may begin.

The above principle also applies when a user wish to connect to the Internet from a computer connected to a telecommunications network. The user connects to a data-communications network by dialing a B-number to a modem pool, from which accessing the data-communications network is possible. There are no information or interaction possibilities with the called server other than this access opportunity.

Applicants have identified that there is a problem in the present way of accessing the Internet for specific data objects because of the non-obvious way of addressing data objects. There is further a need in the telecommunications industry to provide a simpler way of accessing the Internet and to guide a user by other means than a modem number to call, from where the user is left on her own to be further guided to the desired homepage or data object.

SUMMARY

The present invention overcomes the above identified deficiencies of identifying and finding a data object and navigate between a set of data objects by applying a novel connection between a data-communications network and a telecommunications network.

In one aspect of the present invention a technique for connecting a dialed B-party number to a data object is described. A data object can for example be graphical, text, sound, voice, animations, static or dynamic pictures, or any combination. The connecting of a B-party number to a specific data object, hereafter referred to as phonepage, will allow an A-party direct access to information that a B-party wishes to display to a calling party. The phonepage resides in a memory in a telecommunications network, or in a memory in a data-communications network connected thereto. The phonepage may have a similar appearance to an Internet web page, but may also take other appearances. The displaying of the phonepage may be made dependent upon the capabilities of the A-party user equipment.

Dependent on the type of equipment used by the A-party, the node storing the phonepages may, upon detection of type of equipment, select the most advantageous way of displaying a selected data object.

Also, dependent on the A-party user equipment, the phonepage may provide different levels of interaction possibilities, i.e., only display information, or be a fully interactive data object with a duplex communication between the A-party and the node housing the memory in which the phonepage is stored.

The phonepages may be configured to be displayed automatically or by indication from the A-party. In a variant of the invention also a B-party has the same capabilities of obtaining phonepages upon reception of an A-number in conjunction with an incoming call.

In another aspect of the present invention, a node in a data-communication or telecommunication system is described. The node consists of at least a database memory including at least indications of the phonepages and upon access from a remote request, respond with said indication.

The transfer of the indication to a calling A-party may be dependent on type of connection and access technology used in the connection. For example in a connection where both circuit switched and packet switched communication is simultaneously possible, the indication may be transferred on a packet switched communication resource and, e.g., voice communication may be initiated on the circuit switched communication resource. In other types of connections, two data flows may be set-up on one or several simultaneous packet switched communication resources, e.g., speech and data transfer. Another example is when voice communication is initiated over a circuit switched communication resource and the phonepage indications are transferred over a packet switched channel with limited performance such as an SMS channel.

DETAILED DESCRIPTION

First a network overview. The present invention will now be described with references to a telecommunications system based on GSM as a circuit switched communication system and GPRS as a packet switched communications system. It should however be noted that the embodiments described are to be considered exemplary and that other packet and circuit switched systems may equally well be considered, both fixed- as well as mobile- and with any access technology, e.g., Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Time Division Duplex (TDD), Frequency Division Duplex (FDD) or any combinations thereof. The invention is not restricted to any specific type of communications network or access technology.

FIG. 1 illustrates a communication infrastructure overview, 10, where a number of different communication networks are interconnected. FIG. 1 includes both nodes included in a Circuit Switched (CS) mobile communication network, e.g., a Mobile Switching Center (MSC), 118, and Base Station Subsystem (BSS), 112, as well as nodes included in a Packet Switched (PS) mobile communication network, e.g, Serving GPRS Support Node (SGSN), 114 and a Gateway GPRS Support Node (GGSN), 116. Typically, the SGSN includes functionality such as re-segmenting data packets according to one protocol into data packets according to protocols used over the air interface. The SGSN also includes control mechanisms for one or several BSS, 112 as well as Quality of Service (QS) mechanisms. The GGSN includes functionality required to maintain communication between a mobile packet data network and other packet data networks e.g., data network 120. The CS part of the network connects to a PSTN network, 140, and the PS part of the network connects to a data network, 120. The data network may be both an external or internal network, i.e., with global or limited access possibilities. As shown, the PS and CS parts of the network may also be interconnected by way of an interface between the MSC, 118 and the SGSN, 114. The BSS, 112, may serve both the PS as well as the CS part of the network with packet switched (161) as well as circuit switched (162) communication resources over the air, to provide mobility to both PS and CS service users and their User Equipment (UE), 100. The UE, 100, may for example be a mobile telephone or a mobile telephone connected to any kind of data equipment, e.g., Personal Digital Assistance Devices (PDA) or Laptop computer. The PSTN, 140, provide users (user devices) connected to the fixed network with service, e.g., to "plain old telephones" (POTs), facsimile or data modem devices, 150. Other examples of devices connected directly or indirectly to the PSTN, 140, are ISDN terminals and communication devices connected via a Digital Subscriber line (DSL) (e.g., ADSL, HDSL and XDSL).

The data network, 120, typically includes one or several routers (not illustrated) and data bridges such that several nodes may be interconnected and communicate with each other. The data network used in connection to the present invention includes also a data object server, 130. Typically, pluralities of data object servers are included in a data network, although, for reasons of explanation and clarity, only one data object server, 130, is illustrated in FIG. 1. Exam
