Definitions
- the present invention relates to a method for implementing push services, in particular for implementing push services in a GPRS network.
- Push services are application-initiated services.
- An application server that offers such services would like to give a subscriber a specific one without explicitly requesting it
- a subscriber generally has to register with the application server in advance or
- ISP Internet Service Provider
- GPRS network General Packet Radio Services
- SGSN Serving GPRS Support Node
- GGSN Gateway GPRS Support Node
- PDP Packet Data Protocol
- IP Internet Protocol
- a method for realizing IP-based services is provided, which is initiated by an application server and for a subscriber of a mobile
- Communication network are provided without its request, in which a. from the participant a data connection via the mobile
- Communication network is requested, b. a data connection is established within the mobile communication network between the subscriber, a control node (SGSN) and an interface node (GGSN), c. a first message regarding the established data connection is sent to a switching node connected to the mobile communication network, d. a second message regarding the established data connection is sent from the switching node connected to the mobile communication network to the application server, e. an IP service is initiated by the application server and provided to the subscriber.
- SGSN control node
- GGSN interface node
- a GPRS network is selected as the mobile communication network.
- the control node is then a Serving GPRS Support Node (SGSN), the interface node is a Gateway GPRS Support Node (GGSN).
- the data connection that is established between the SGSN and the GGSN is a PDP context that is established using a GTP protocol.
- the GTP protocol is described, for example, in the publication “3GPP 29.060, 3rd Generation Partnership Project; Technical Specification Group Core Network; General Packet Radio Service (GPRS); GPRS Tunneling Protocol (GTP) across the Gn and Gp Interface ".
- An IP address from an address reservoir is preferably assigned to the subscriber.
- the GGSN particularly preferably assigns the subscriber an IP address, generally a dynamic address, from an address reservoir available to the GGSN. naive IP address too.
- the address reservoir is a database available to the GGSN.
- An address reservoir is allocated by ICANN. As already mentioned at the beginning, this means that the IP address is only assigned when the subscriber is activated or a PDP context is established.
- an “open service access / parlay gateway” is used as the switching node.
- OSA / Parlay Open Service Access / Parlay
- the use of a switching node (OSA / Parlay gateway) operating in accordance with the "Open Service Access / Parlay" specification has the advantage that security mechanisms for the establishment of the communication connection and the like are available from such a switching node in the OSA / Parlay technology Data transmission can be used.
- the IP address which was assigned to the subscriber is stored in the control node.
- the IP address assigned to the subscriber is preferably both of the first message in step c. of the procedure as well as the second message in step d. attached.
- This means that the application server is informed of the established data connection within the mobile communication network between the control node and the interface node, ie generally via the PDP context, by means of the first and the second message.
- the application server is thus informed whether a data connection, preferably a PDP context, has been established.
- the first message relating to the data connection within the mobile communication network between the control node and the interface node is preferably sent to the switching node by the control node, preferably an SGSN.
- the application server can be located in the switching node, i.e. Register preferably in an OSA / Parlay gateway to use a so-called "data session control" interface with regard to a precisely named subscriber.
- This interface is described in the publication 3GPP TS 29.198-8 of the UMTS Release 4.
- the first message ie the message to the switching node, which is preferably an OSA / Parlay gateway
- the switching node which is preferably an OSA / Parlay gateway
- CAMEL Mobile Enhanced Logic
- CAP Application Part
- This protocol is specified in 3GPP TS 29.078. Accordingly, the OSA / Parlay gateway is informed of a successful establishment of a data connection, in particular a PDP context, via this protocol.
- the first message is a so-called "InitialDPGPRS" operation.
- MSISDN In addition to a subscriber number, a so-called MSISDN, this message also contains the IP address assigned to it.
- the present invention has the advantage that it can also be used to provide IP push services in particular for GPRS subscribers.
- an application server that wants to provide a push service for a subscriber is informed fully automatically of the existence of a data connection or a PDP context and of the IP address assigned to the subscriber.
- FIG 1 schematically shows an embodiment of processes of the inventive method and in
- FIG. 2 shows a further exemplary embodiment of sequences of the methods according to the invention.
- OSA / Parlay shows the essential steps of the method according to the invention, which are carried out using the so-called "OSA / Parlay” technology.
- the OSA / Parlay technology itself is known and is described, for example, in US Pat
- FIG. 1 shows a mobile communication network, namely a GPRS network with a control node SGSN and an interface node GGSN.
- an application server AS which wants to provide or provide a service, namely a push service, to a subscriber MS without his explicit request.
- a switching node OSA / P GW Open Service Access / Parlay Gateway
- OSA / P GW Open Service Access / Parlay Gateway
- Such a switching node can be a so-called OSA / Parlay gateway.
- the switching node is used to monitor and control the establishment of a communication or data connection between the application server and the mobile communication network.
- the later data transmission or communication itself does not take place via the switching node, but via the data or. Communication connection directly between the application server AS and the mobile communication network. This data connection is established between the application server AS and the GGSN of the GPRS network and the subscriber MS. The Switching nodes no longer have a direct influence on this data transmission.
- the application server AS which would like to provide a push service for a specific subscriber MS, can be registered with the corresponding OSA / Parlay gateway for the use of a so-called “data session control” interface with respect to this subscriber.
- This data Session control interface is specified, for example, in the publication "3GPP TS 29.198-8".
- the application server logs on to the OSA / Parlay gateway as application server AS and is henceforth informed about the PDP contexts of the subscriber concerned.
- the subscriber MS for whom the AS wants to provide the push service, requests a data connection from the mobile communications network GPRS to an external network, such as, for example, the Internet or an intranet of a company.
- an external network such as, for example, the Internet or an intranet of a company.
- This requirement on the part of the MS participates at the SGSN.
- a data connection a so-called PDP context, is set up between the SGSN and the GGSN via a so-called GTP protocol.
- the GTP protocol is explained, for example, in the printing step "3GPP TS 29.060".
- the GGSN then assigns the subscriber MS a dynamic IP address from an address reservoir available to the GGSN.
- Dynamic as already explained at the beginning, means that the IP address is only assigned at a point in time when the PDP context is activated and is only valid as long as the PDP context is activated.
- the IP address assigned to the subscriber MS is communicated to the SGSN.
- the OSA / Parlay gateway is informed about the successful establishment of the PDP context.
- This message which is sent from the mobile communication network, in particular from the SGSN, to the OSA / Parlay gateway, takes place by means of a so-called “Customized Applications for Mobile Enhanced Logic (CAMEL) Application Part” (CAP) protocol.
- CAMEL Mobile Enhanced Logic
- CAP Application Part
- This known protocol is described in the publication "3GPP TS 29.078" explained.
- the message that is sent from the SGSN to the OSA / Parlay gateway is referred to as the “initial DPGPRS” operation. It contains a subscriber number of the subscriber MS (MSISDN) and the IP address assigned to the subscriber MS.
- MSISDN subscriber number of the subscriber MS
- IP address assigned to the subscriber MS IP address assigned to the subscriber MS.
- the application server AS is also informed that the subscriber MS has set up an IP data connection, namely a PDP context.
- This message is sent to the application server AS by means of a so-called OSA "Data Session Control" interface.
- the corresponding message that is sent to the application server AS in this case contains the MSISDN of the subscriber MS and its current IP address.
- the message is written as " dataSessionEventNotify ".
- the application server AS now has all the information it needs to be targeted, i.e. immediately for the subscriber MS to initiate a push service.
- FIG. 2 schematically shows a further exemplary embodiment of process sequences of the methods according to the invention.
- FIG. 2 shows the mobile communication device already known from FIG. cation network GPRS with the SGSN and the GGSN, the switching node OSA / P GW, the application server AS and the subscriber MS.
- the application server AS would like to provide a WAP application for the subscriber MS.
- This is a WAP application which, when the PDP context is activated, gives the subscriber MS a WAP push notification, ie a notification, regarding incoming emails for the subscriber MS.
- the application server AS registers at the OSA / Parlay gateway OSA / P GW for the use of a “data session control” interface with respect to the subscriber MS.
- the subscriber MS requests a data connection to an external network, for example the Internet, from the mobile communication network GPRS, in particular at the SGSN.
- an external network for example the Internet
- a data connection a so-called PDP context, is set up between the SGSN and the GGSN via the GTP protocol already mentioned.
- the GGSN assigns the subscriber MS a dynamic IP address from an address reservoir available to it.
- the GGSN then confirms to the SGSN that the PDP context between the GGSN and the SGSN has been successfully established. He also informs the SGSN of the IP address assigned to the subscriber MS.
- the OSA / P-GW is successful Structure of the PDP context informed.
- the corresponding message that is sent by the mobile communication network is, as already mentioned in FIG. 1, “InitialDPGPRS”.
- this message In addition to a call number MSISDN of the subscriber MS, this message also contains the IP address assigned to it by the GGSN.
- the WAP application server AS is informed by means of the OSA "Data Session Control" interface already introduced and explained in FIG. 1 that the subscriber MS concerned has set up an IP data connection or a PDP context. In addition to the MSISDN, this contains Message that is referred to as "dataSessionEventNotify", the current IP address of the subscriber MS.
- the WAP application server can initiate its WAP application for the subscriber MS.
- it consists of informing the subscriber MS about incoming e-mail messages.
- the WAP application server AS inquires on an e-mail server using a so-called “post office protocol” (POP3) whether there are electronic messages for the subscriber MS.
- POP3 post office protocol
- the WAP application server When there are messages or emails for the subscriber MS, the WAP application server initiates a WAP push
- This WAP gateway acts here as a so-called WAP Push Proxy Gateway.
- the WAP push request includes a notification of the emails received.
- the WAP application server AS communicates with the WAP Push Proxy Gateway according to a so-called WAP Push Access Protocol (PAP), which is known from the WAP V2.0 standard.
- PAP WAP Push Access Protocol
- the PAP can be laid out over a so-called HTTP VI .1 protocol and one use the so-called POST method.
- the WAP V2.0 standard also leaves other paths open.
- the WAP gateway sends the notification of the received e-mails via the GGSN to the subscriber MS.
- Communication takes place here using a so-called WAP Push OTA ("over-the-air") protocol, which is known from the WAP V2.0 standard.
- WAP Push OTA over-the-air
- This protocol is laid down via the HTTP (Hyper Text Transfer Protocol) VI .1
- the HTTP protocol is the standard protocol for client-server communication on the Internet This protocol is based on TCP / IP
- the subscriber MS or his mobile communication terminal support a so-called WAP Service Indication from WAP V2.0.
