Definitions
- the present invention relates generally to setting up connections and, more particularly, to setting up a peer-to-peer IP connection between communication devices.
- IP Internet Protocol
- a server is required to set up a peer-to-peer IP connection, which is time consuming and cumbersome.
- the server is used to keep track of IP addresses and to enable the connection.
- the server is effectively contacted by all possible parties and the server thus holds IP addresses associated with all the parties.
- the server finds the current IP address associated with the second party.
- the connection can be routed through the server.
- aspects of the invention provide a mechanism for setting up a peer-to-peer IP connection, where the mechanism is fast and easy for the users of the first and second devices.
- a method in a first communication device (first device) for setting up a peer-to-peer IP connection between the first device and a second communication device (second device) comprises the steps of: sending in an Short Message Service (SMS), Multimedia Messaging Service (MMS) or similar message to the second device, a request for setting up the peer-to-peer IP connection between the first device and the second device; sending an IP address of the first device in a message to the second device, or receiving an IP address of the second device in a message from the second device; and setting up the peer-to-peer IP connection between the first device and the second device.
- the setting up is initiated by any one of the parties of the first device and the second device, having obtained the IP address of the other party in the step above, by connecting to the other party by means of the IP address of the other party.
- a method in a second communication device (second device) for setting up a peer-to-peer IP connection between a first communication device (first device) and the second device comprises the steps of: receiving in an Short Message Service (SMS), Multimedia Messaging Service (MMS) or similar message from the first device, a request for setting up the peer-to-peer IP connection between the first device and the second device; receiving an IP address of the first device in a message from the first device, or sending an IP address of the second device in a message to the first device; and setting up the peer-to-peer IP connection between the first device and the second device.
- the setting up is initiated by any one of the parties of the first device and the second device, having obtained the IP address of the other party in the step above, by connecting to the other party by means of the IP address of the other party.
- an arrangement in a first communication device comprises a Short Message Service (SMS), Multimedia Messaging Service (MMS) or similar message communication unit, adapted to send, in an SMS, MMS or similar message to the second device, a request for setting up a peer-to-peer IP connection between the first device and a second communication device.

- FIG. 3 is a schematic block diagram illustrating an arrangement in a first communication device according to the present invention.
- FIG. 4 is a schematic block diagram illustrating an arrangement in a second communication device according to the present invention.
- the invention is defined as a method and an arrangement which may be put into practice in the embodiments described below.
- FIG. 1 shows a first communication device 100 (referred to herein as first device 100 ), adapted to communicate with a second communication device 110 (referred to herein as second device 110 ).
- the first device 100 and second device 110 are included in a communication system, such as, e.g., a radio communication system using technologies such as, e.g., Global System for Mobile communication (GSM), Wideband Code Division Multiple Access (WCDMA), a Plain Old Telephone Service system (POTS), or the Internet.
- GSM Global System for Mobile communication
- WCDMA Wideband Code Division Multiple Access
- POTS Plain Old Telephone Service system
- the first device 100 and second device 110 may be, e.g., a portable device, a mobile phone, a Personal Digital Computer, a POTS device, a computer or any other communication device.
- the first device 100 and the second device 110 further have a respective IP address and a respective telephone number or some other kind of address that make them capable of communicating via Short Message Service (SMS), Multimedia Messaging Service (MMS) or similar, using an SMS, MMS bearer or a similar bearer that may be circuit switched or packet switched.
- SMS Short Message Service
- MMS Multimedia Messaging Service
- the respective first and second device 100 , 110 may communicate via an IP route 120 and/or an SMS, MMS and/or similar route 130 .
- the first device 100 and second device 110 may include a Subscriber Identity Module (SIM) card or similar function, such as Universal Mobile Telecommunications System SIM (USIM) or IP Multimedia Subsystem SIM (ISIM), which function includes the telephone number or an other kind of address of the device.
- SIM Subscriber Identity Module
- USIM Universal Mobile Telecommunications System SIM
- ISIM IP Multimedia Subsystem SIM
- SMS is used for any SMS, MMS or any similar message and/or service.
- the present method uses the feature of a communication system in which devices with a SIM card or a similar card/device, or a telephone number can directly be contacted as soon as the devices are turned on, via the SMS, MMS or similar bearer.
- the present method may further use a feature used in SMS, MMS or similar, defined in some communication systems, such as radio communications systems, which directly address a specified port, not appearing in the device's normal SMS inbox and thereby auto start certain applications.
- the first device 100 or the second device 110 is a computer with a SIM (or ISIM or USIM) card
- a SIM or ISIM or USIM
- GPRS General Packet Radio Service
- Such a computer can potentially also be connected to the Internet through a landline cable, such as, e.g., Asymmetric Digital Subscriber Line (ADSL) or a broadband access.
- DSL Asymmetric Digital Subscriber Line
- SIM or USIM, or ISIM or similar
- This identity can be its Mobile Station International Integrated Service Digital Network (MS ISDN) number, such as in the SMS case, or it can be a Session Initiation Protocol Uniform Resource Identifier (SIP URI), as is the case with ISIM (ISIM is the SIM card application used in the IMS case).
- MS ISDN Mobile Station International Integrated Service Digital Network
- SIP URI Session Initiation Protocol Uniform Resource Identifier
- the first device 110 and the second device can, e.g., send and receive SMS, MMS or similar messages over the GSM network or alternatively over the land line cable over the Internet with a direct connection to the Short Message Service Center (SMSC).
- SMS Short Message Service Center
- the term “telephone number” is used, but the term also covers any similar address making it possible to send and receive.
- SMS, MMS or similar service that the first device 100 and second device 110 use is that the second device 110 is always available as soon as the user of the second device 110 installs the SIM (or USIM or ISIM) card into the second device 110 .
- SIM or USIM or ISIM
- a similar service in the present method should also have this feature, but can be more efficiently implemented by using, e.g., the SIP URI identity instead of the MS ISDN. Therefore the present invention also covers alternative services to SMS.
- the second device 110 is addressable by its telephone number or similar, independent of its actual IP address.
- FIG. 2 is a combined flow chart and message sequence diagram describing a method for initiating a peer-to-peer IP connection between the first device 100 and the second device 110 by using an SMS, MMS or similar message to initialize the IP connection.
- the method may comprise the following steps:
- the first device 100 wishes to initiate a peer-to-peer IP connection between the first device 100 and the second device 110 .
- An exemplary scenario may be that the user of the first device 100 wishes to share multimedia content with user of the second device 110 over the peer-to peer connection.
- the first device 100 sends a message to the second device 110 , using the telephone number (or similar) of the second device 110 .
- This message is also referred to as the first message herein.
- the message comprises a request for setting up a peer-to-peer IP connection between the first device 100 and the second device 110 .
- the message may further comprise the IP address of the first device 100 .
- the IP address of the second device 110 may be sent in a second message, which will be described below.
- the first message may further comprise the telephone number of the first device 100 .
- This is performed in a common way, i.e., information about the telephone number of a sender of an SMS, MMS or similar message is included in the SMS, MMS or similar message.
- This may be performed automatically, for example, by an application such as Internet browser application or an IP telephony application, e.g., if the first device 100 wishes to share an application with the second device 110 , such as an IP telephony application that the first device 100 wishes to use for communicating with the second device 110 .
- the user of the first device 100 then starts the application and chooses or enters the telephone number of the second device 110 .
- the application then automatically sends the message to the same application in the second device 110 .
- the message further comprises a trigger to start the application in the second device. This may, e.g., be accomplished by the first device 100 addressing the first message to a specific port at the second device 110 , which port is associated with the application. If the second device includes that application, it has registered that any message addressed to that specific port is associated with the application. The message then auto starts the application in the second device 110 .
- the message is parsed in the second device 110 .
- the request is identified, i.e., that the first device 100 wishes to initiate a peer-to-peer IP connection between the first device 100 and the second device 110 .
- the sender may also be identified. This may be performed by identifying the telephone number, e.g., by checking the telephone number against a phone book in the second device.
- the second device 110 may comprise a user-defined list of user of devices who are allowed to form peer-to-peer IP connections to the second device 110 . If there is such a list and the user of the second device 110 and/or the first device 100 is not on the list, the procedure ends and no peer-to-peer IP connection is set up.
- the first device 100 is connected to the second device 110 for setting up a peer-to-peer IP connection between the first device 100 and the second device 110 , using the IP address comprised in the first message.
- the first message was sent to a specific port in the second device 110 .
- the port being associated to a specific application
- the application in the second device 110 is started automatically.
- the application in the second device 110 then initiates the peer-to-peer IP connection between the application in the first device 100 and the same application in the second device 110 .
- the first device 100 may be informed of the IP address of the second device 110 and an identification identifying the second device 110 during the set up.
- step 203 In an alternative to step 203 , three steps 203 a , 203 b and 203 c may be taken, which steps are illustrated as dashed arrows and square 203 a , 203 b and 203 c .
- no IP address was included in the first message and therefore the second device cannot initiate the peer-to-peer IP connection. Instead, the second device 110 provides the first device 100 with the IP address of the second device 110 and the first device 100 initiates the start up of the peer-to-peer IP connection.
- the second device 110 replies to the first message from the first device 100 by sending a second message. This may be performed automatically without involving the user of the second device 110 .
- the second message includes the current IP address of the second device 110 .
- the second message may further include an identification number and a request for a peer-to-peer IP connection between the first device 100 and the second device 110 .
- the first device 100 parses the second message and extracts the IP address and also the identification if included.
- the first device 100 connects to the second device 110 for setting up a peer-to-peer IP connection between the first device 100 and the second device 110 , using the IP address included in the second message. This may be performed automatically without involving the user of the first device 100 .
- the first device 100 may now communicate with the second device 110 using the set up peer-to-peer IP connection.
- the first device 100 and the second 110 may share the application.
- the user of the first device 100 wishes to use the peer-to-peer IP connection to browse on a server 140 , e.g., a HyperText Transfer Protocol (HTTP) server, in the second device 110 .
- the second device 110 includes the server 140 that provides any generic content that can be associated with any type of rendering program such as a browser, audio and or video codecs and also Global Positioning System (GPS) positions, Personal Information Management (PIM) and similar.
- the first device 100 and the second device 110 may include a respective Internet browser application.
- An Internet browser is a software application that enables a device to display and interact with text, images, and other information located on a HTTP server. Internet browsers communicate with HTTP servers to fetch information stored at the HTTP server.
- a simple Hypertext Markup Language (HTML) page can be dynamically generated to provide a list of available files. According to this embodiment, the present method includes further steps described in detail below.
- the second device 110 starts an application to act as a server 140 . This is performed by the trigger to start an application, e.g., an Internet browser application.
- the first message may be a trigger to start a server application in the second device 110 , i.e., a software process to act as a multimedia network server at the Internet.
- the first device 100 starts its Internet browser if not already started (e.g., the Internet browser may be started already in step 201 when sending the first message, as discussed above).
- the first device 100 uses the IP address of the second device 110 and possibly also the identification identifying the first device 100 included in the first or second message.
- the first device 100 uses the IP address of the second device 110 for accessing server 140 . This may be performed by the first device 100 sending a request to access the server 140 in the second device 110 , to the IP address of the second device 110 .
- the identification may be included in this request as an authentication measure and in this case, the server 140 lets the first device 100 access the server 140 if the identification is identified as authorized.
- the identification may be further processed by the first device 100 in a previously agreed way, so that the second device 110 is further assured that the request to set up the peer-to-peer IP connection is from a legitimate user (e.g., the first device 100 ).
- the second device 110 recognizes the new signature from the identification it sent out and stores information indicating how the identification it sent out would be further processed by the first device 100 . This enables the second device 110 to recognize the new signature.
- the user of the first device 100 now can browse the content of the second device 110 and stream or download media files accessible from the Internet browser of the first device 100 and/or the second device 110 .
- the present method may be used to start instant messaging sessions, voice over IP connections, or any IP-based service between two devices.
- the personal computer can send an SMS, MMS or similar message to inform the device whenever the dynamic IP address of the server associated with the personal computer is updated. This allows the user of the device to access all content stored on the server associated with the computer.
