Definitions

• Mobile radio networks in particular packet-switched mobile radio networks such as GPRS / UMTS / etc networks
• packet-switched mobile radio networks such as GPRS / UMTS / etc networks
• GPRS / UMTS / etc networks are known to the person skilled in the art, for example from the standardization of such mobile radio networks (see, for example, www.etsi.org, www .3GPP.com).
• contexts corresponding to, for example, virtual channels
• packet data are transmitted to one or more data connections via one or more physical data channels, in each case at least on both sides of the physical connection from the subscriber to the mobile radio network being defined by a context, which packets are transmitted via the at least one physical channel Data connection of which subscriber belong (for example, by entries in a header of a packet, which header can be assigned at least on both sides of a channel of a data connection and / or a subscriber). Details of this are known to the person skilled in the art from packet switching mobile networks already known per se, such as GPRS or 3G.
• Such connections can lead via (at least) an air interface of a mobile radio network.
• they can be set up by the subscriber (that is, with his mobile terminal) and theoretically remain for an arbitrarily long period of time.
• the dismantling of the contexts can be done by the participants. It can happen that such a data connection on the air interface of a
• Mobile network interrupted by an external event For example, if the subscriber drives with his terminal in an underground car park or a tunnel or the air interface is disturbed in any other way. In this case, the terminal can not signal the degradation of the data connection (or the context relating to the data connection) due to the interrupted air interface to the mobile network.
• non-real-time-capable data connections Contexts
• resources in the mobile network are unnecessarily (further) classified as reserved (because they are not resolved) and, on the other hand, costs are charged to the subscriber for further reserved resources (data connections / contexts) by billing his contexts / data connections.
• the mobile network thus uses its resources only suboptimal and the billing is not optimal.
• the object of the present invention is to treat a disruption of data connections or contexts of data connections in the event of an interruption of an air interface as efficiently and reliably as possible.
• the object is solved in each case by the subject matters of the independent claims.
• a detection of an interruption of an air interface, via which a data connection or. a context concerning a data connection is made surprisingly easy and efficient by setting up a
• Signaling context of the subscriber as a real-time classified signaling context.
• Signaling contexts are used by a subscriber (in particular a terminal) for setting up and controlling the or. all contexts of the participant.
• the signaling contexts usually do not have to be set up in real-time.
• monitoring real-time connections on the air interface of a mobile network in mobile networks is relatively easy to implement. If such a real-time connection is interrupted, this is recognized by the mobile network and the affected
• the resources of the "non-real-time" contexts can also be monitored by monitoring real-time contexts and, if necessary. be released or modified. If a subscriber recovers the connection (if he has a connection via the air interface, etc.) and there are still context resources available, the connections (contexts) can be synchronized.
• the quality requirements (quality of service) can be negotiated back.
• the minimum quality of service area can be separately identified in a charging ticket for the subscriber and their data connection, and can be ignored in billing (charging the subscriber's charge and its data link context (E)).
• the invention enables simple and efficient detection of interruptions on the air interface and thus non-real-time data connection contexts of this subscriber.
• the invention can be used in a wide variety of mobile radio networks, in particular in cellular packet-switched mobile networks such as GPRS / 3G or other packet-switching cellular mobile networks.
• Figure 1 shows schematically the communication between a
• Terminal Subscriber (terminal) and a mobile network.
• FIG. 1 schematically shows the communication of a subscriber 1 with a mobile radio terminal MS1 via an air interface 2, a mobile radio network base station 3 of a cellular mobile radio network with a monitoring device 4 and switching devices 5, 6 with, for example, another mobile station (via a further base station 7 and a further air interface 8) 9th
• the transmission of data between the mobile station 1 and the mobile radio network (3, 4, 5, 6, 7) via the air interface 2 can in principle be circuit-switched, wherein a physical line from the mobile station of the
• Subscriber 1 to the mobile station 9, etc. can be switched through or packet-switched, wherein data to be transmitted from a mobile station 1 to another mobile station 9 via one or more physical channels in (eg virtual) packet connections can be transmitted.
• data relating to several data connections could be transmitted in one (or more) physical channel and to the receiver (mobile network or mobile station, etc.) due to an association of identifiers in Data packets (headers) are assigned to a context, ie a data connection.
• an interruption of the air interface by external events such as an underground car park or a tunnel and thus an interruption (possibly for the
• Such data connections are, however, widely implemented as non-real-time capable data connections (real-time-capable data connections are data connections for which minimum average and / or maximum data connections
• Transmission rates or transmission times are guaranteed in general or for certain conditions, while they are usually not guaranteed for non-real-time data connection etc).
• the monitoring (at least) of such a non-real-time data connection context 10 of a subscriber 1, via which (10) data (for the Internet transmission, email data, other arbitrary data) are transmitted, is established by constructing a signaling context 11 of the subscriber as a real-time signaling context or (on the part of the mobile station and the mobile network it informs) which is monitored by the mobile network, wherein the mobile network interrupts one or all data connection contexts 10 upon detection of an interruption in the subscriber's signaling context (monitored as "real-time capable") this subscriber can be accepted by the mobile radio network and / or by the mobile terminal 1.
• a charge calculation for the data connection context can be started thereon, if necessary, Moreover, the data connection context can be mobile-network-side and / or mobile-radio terminal permanently or provisionally classified as terminated (terminated) and / or its quality or other characteristics changed.
• a signaling context is expediently stored by the mobile station and / or by a device of the mobile radio network, to which signaling text which data connection contexts are assigned in such a way that they belong to the same subscriber and / or that they terminate upon detection of an interruption of the signaling context (on the air interface etc) as etc. are to be classified.
• a device 12 for establishing a signaling connection is provided as a real-time context.
• a memory 13 can be provided in which the contexts used by the mobile station 1 can be stored in a file 14 as in the example, wherein a signaling context can be stored, which properties it has and data connection contexts for the subscriber 1 (via the Signaling context etc.) Were created.
• data connection contexts may have data concerning properties of the context such as real-time capability / non-real-time capability, header, start and end of the data connection, quality, etc. be included.
