Definitions
- the signaling for setting up and clearing down 64 kbit user channel connections for controlling ISDN services is carried out on the basis of ITU-T signaling system No. 7 - also as SS NR. 7 designated.
- the actual task of signaling procedure No. 7 is the exchange of signaling messages within the communication networks.
- the signaling messages are exchanged by the user parts - also referred to as user parts - within the reference model.
- user parts - also referred to as user parts - within the reference model.
- the TUP was implemented as the first application in signaling procedure no. 7.
- the ISUP was defined on the basis of the TUP for the general definition of the ISDN and for the determination of the signaling within the ISDN.
- the main tasks of the ISUP are:
- the ISDN user part makes use directly of the message transfer part ⁇ - MTP - and the control part for signaling connections - SCCP, layer 4 -, the ISUP itself is thus the layer 4 to 7 classified in the OSI reference model.
- the ISDN user part controls both the signaling in stages for reaching the destination and the end-to-end signaling relationship between the originating and destination switching center. With the help of the section-by-section signaling, the path for the useful channel connection and the signaling connection is sought and, according to appropriate commands, set up.
- the MTP is used for this.
- the ISUP uses the services of the SCCP.
- the actual signaling information is exchanged in the ISDN user part. All underlying layers ensure that this information is transmitted securely and reaches the addressed user part.
- the end-to-end signaling of the SCCP based on a TCAP dialog is used for the exchange of the end-to-end signaling messages for handling ISDN service features.
- the exchange of the messages of the ISDN user part with the corresponding associated parameters forms the actual signaling between the ISDN switching devices.
- the messages are transferred to the control in the switching equipment. On the basis of these messages, for example, the paths of the useful channel connections are controlled and the coupling elements are switched through accordingly.
- the signaling messages of the ISUP have a defined structure which, in addition to a message header - with the "routing label", "circuit identification code” and “message type" contained therein - for the respective message type ⁇ ⁇ ro r P 1 P 1 ⁇ o Ül o C ⁇ o C ⁇
- MLPP represents.
- the additional service Multi-Level Precedence and Pree tion Service (MLPP) provides the corresponding service users with call handling with several priority levels.
- the additional service MLPP is provided to the service user on request and can either refer to the phone number and / or the service.
- the MLPP additional service provides priority, i.e. calls with a higher priority (call with a higher priority than the priority of the previously received call) to the service user or B subscriber to a predetermined destination - e.g. C-subscriber or interrogation station - redirected if the non-interruptible service user is busy or does not answer.
- an interrupted active connection can also be forced by a priority call or a call with a higher priority - also referred to as a forced release - whereby
- Participant has the opportunity to confirm the forced triggering, or if there are no resources, i.e. if there is a lack of free user or B channels or if there is a lack
- the "Multi-Level-Precedence and Preemtion Service" or MLPP feature is mainly used in military networks.
- the additional service MLPP is currently only defined by the ITU-T:
- ITU-T 1.255.3 Integrated Services Digital Network
- ISDN General Structure and Service Ca capabilities
- MLPP Multi-Level Precedence and Preemtion Service
- ITU-T Geneva, September 1990.
- the MLPP parameter comprises 6 data octets, through which, among other things, the respective MLPP priority - or "Precedence Level -, the MLPP network and the network domain -" MLPP service domain "as well as further MLPP-specific information for those to be set up MLPP connection or MLPP communication relationship are determined.
- the line bundles or dedicated lines used specifically for the implementation of higher-level communication networks are underutilized due to the bundle reserves required for this purpose, and are therefore associated with high economic outlay.
- the administration of higher-level communication networks is associated with high operational and administrative expenditure, among other things, routes with overflow bundles are required for reasons of availability.
- the invention is based on the object of minimizing the administration and thus the economic outlay for setting up and operating superordinate or superimposed communication networks.
- the object is achieved by a method according to the features of the preamble of claim 1 by its characterizing features.
- the essential aspect of the inventive method for establishing communication links between in at ⁇ a communication network least arranged and at least one group associated subscriber terminals is that it is checked at a to be set up within the group communication session if a predeterminable, maximum number of within the group buildable or established communication relationships is exceeded. If the maximum number is determined to be exceeded, the communication relationship to be established is not established.
- the main advantage of the method according to the invention is the simple administration of superimposed communication networks using existing line bundles and routes and the bundle losses avoided thereby.
- expensive dedicated lines for connecting sub-communication networks can be saved and existing transmission resources of a third network operator can be used under favorable conditions
- a predeterminable priority is assigned to the communication relationship to be established. If it is determined that the maximum number of communication relationships that can be established or established within the group is exceeded, at least one currently lower priority than the priority of the communication relationship to be established within the group is determined and selected. Subsequently, the selected communication relationship is triggered or parked or held and the communication relationship to be established is established - claim 2.
- the predeterminable prioritization of communication relationships to be established means that, for example, urgently required transmission resources are provided when the overall amount available to the group is exhausted. initially secured transmission resources.
- the allocable amount of a group Ü can bertragungsressourcen, ie the maximum number of unforeseenbarer within the group communication sessions at the network utilization resource at times of normal demand for transmission ⁇ - be construed - Normal needed.
- the predefinable prioritization of communication relationships to be established ensures, even at times when there is a high need for transmission resources - peak demand - that despite the design of the range of resources allocated to the group for normal needs, important communication relationships are established within the group - with the triggering of low-priority communication relationships.
- the transmission resources provided by a communication network can thus be allocated or reserved in a particularly “resource-optimized” manner, as a result of which the economic outlay for setting up and operating higher-level or higher-level communication networks is kept low.
- At least a part of the communication relationships established within the group is advantageously assigned a priority in accordance with the ISDN-compliant additional service “Multi-Level-Precedence and Preemtion Service” or “MLPP” - claim 5.
- MLPP Multi-Level-Precedence and Preemtion Service
- the invention This represents an extension of the MLPP standard in the direction of higher-level or higher-level communication networks.
- 1 shows a higher-level communication network which has a plurality of subscriber connections and in which communication rela connections between the subscriber lines are established
- FI G 2 the sequence of the method according to the invention when establishing a communication relationship within the superordinate communication network
- FIG. 3 shows a first embodiment variant of a proprietary extension of the MLPP parameter transmitted in the IAM of the ISUP when establishing a communication relationship as part of the MLPP signaling
- FIG. 4 shows a second embodiment variant of a proprietary extension of the MLPP parameter.
- FIG. 1 shows a block diagram of an exemplary arrangement of two SUB communication networks SUB 1,2 which are combined via a public communication network KN to form a superordinate or superimposed communication network or company network GRP - illustrated by a broken line in FIG. 1.
- the two SUB communication networks SUB 1, 2 represent, for example, 2 separate, e.g. represent communication networks implemented in distributed company locations, which can be connected to one another via the public communication network KN.
- the sub-communication networks are e.g. private switching equipment PBX and corresponding primary multiplex connections PA connected to switching equipment LE assigned to the public communication network KN.
- the switching facilities LE representing the public communication network KN are interconnected or meshed.
- n_max of, for example, 100 connections or communication relationships conducted simultaneously via the public communication network KN are provided for the communication - ie for voice and data communication - between the two SUB communication networks SUB 1,2.
- n_max for example, 100 connections or communication relationships conducted simultaneously via the public communication network KN are provided for the communication - ie for voice and data communication - between the two SUB communication networks SUB 1,2.
