MABEZ
MABEZ stands for mass traffic to certain destinations (mass call service) in telephone traffic and describes a method of handling peak loads in the telephone network that are difficult to manage. This is in contrast to the easily manageable loads for normal calls via landline or special numbers. In Germany, the number range 0137 is reserved for this by the Federal Network Agency for Electricity, Gas, Telecommunications, Post and Railways (BNetzA, formerly RegTP) . In the past, the predominant use of mass call services was televoting . Since mid-2002, these services have also been increasingly used to participate in competitions in the media.
Use of MABEZ numbers
Mass call numbers are usually used whenever mass calls actually have to be processed, i.e. H. it can lead to an overload of the telephone network, as in voting on events with a large number of participants, z. B. Germany is looking for the superstar or the Eurovision Song Contest . Even with raffles on radio and television, in which only one participant is put through from all callers, mass call service numbers are used almost exclusively. This is a key distinguishing feature from other chargeable value-added numbers such as 0900 numbers, which are not used for a short period of time.
Technical implementation in Germany
According to a specification by the Working Group for Numbering and Network Interconnection (AKNN), mass calls should not affect the otherwise usual network load. Therefore, these service numbers have been divided into five types, which specify the number of manageable calls per minute by the technical service provider. These are:
- Type 1: Less than 1200 calls per minute,
- Type 2: Between 1200 and 3000 calls per minute,
- Type 3: Between 3000 and 10,000 calls per minute,
- Type 4: Between 10,000 and 30,000 calls per minute,
- Type 5: Between 30,000 and 96,000 calls per minute.
This classification allows the network operator of the caller, in the event of an expected overload, not to forward some of the callers from the local exchange at the technical service provider, but to reject them from the start. In this way, a possible overload at the technical service provider of the mass call service number should not arise in the first place, but should be avoided by a precautionary load reduction. A network operator who makes use of this should, according to the AKNN specification:
- signal a lane busy tone to the caller .
- do not rate the call.
Structure of a MABEZ number in Germany
In Germany, the telephone numbers for these services always begin with 0137. This is followed by seven digits. For historical reasons, there are also 16 derived assignments to Deutsche Telekom of mass call service numbers that begin with 01381. An originally planned relocation to the 0902 number range does not seem to be pursued by the Federal Network Agency . A relocation to 0500-Rufnummergasse, which was considered in 2009, was also rejected by the operators due to a lack of interest. The next digit is the tariff digit, which gives the caller information about the price of a call. This is followed by two digits that provide information about which technical service provider operates the phone number. The MABEZ type can also be identified from the first or the first two digits after 0137. The Federal Network Agency has a current list with the assignments.
Costs in Germany
The call to a mass call number from the 0137 number range is chargeable for the caller. A large part of the income is paid out by the technical service provider to the provider of the respective value-added service . In the case of competitions with live participation on radio or television, the general rule is that the costs for the caller are incurred even if one is not put through to the broadcast.
Fixed line costs
- 01371: € 0.14 per call
- 01372: € 0.14 per minute
- 01373: € 0.14 per minute
- 01374: € 0.14 per minute
- 01375: € 0.14 per call
- 01376: € 0.25 per call
- 01377: € 1.00 per call
- 01378: € 0.50 per call
- 01379: € 0.50 per call
The costs can be identified by the first digit after 0137 for the caller from the German landline network. In contrast to the 0900 number range, the charges are not announced free of charge before the call is switched . The connection operator ignores the selection of a connection network operator code in the call-by-call procedure.
Cost of cell phones
The German mobile phone providers charge different, almost exclusively higher prices for dialing MABEZ numbers. These vary greatly depending on the chosen provider and tariff. As a rule, a basic price plus a time-dependent component is charged here. Cellular resellers such as B. debitel , talkline or mobilcom rate MABEZ numbers partly differently than the mobile network operators ( T-Mobile , Vodafone , E-Plus , O 2 ) in the otherwise apparently identical tariff.
Many mobile phone providers use an inconvenient minute cycle for MABEZ numbers, although otherwise a one-second or ten-second cycle applies. This has a particularly negative effect when participating in competitions on radio and television, since a call that does not lead to the broadcast or a waiting loop often only lasts a few seconds.
Costs over IP telephony ( VoIP )
Originally, MABEZ numbers could not be reached via most IP telephony providers. Some NGN network providers and only a few free network providers have followed suit and are now routing these calls. They charge very different prices. In some cases they are identical to the costs in the fixed network. Other VoIP providers charge prices that are comparable to those of the mobile phone providers.
Costs in Austria
In Austria, MABEZ numbers are implemented using the number range 0901-0. This is followed by a number that provides information about the price. If you multiply this number by 10, you get the price in cents / call. An Austrian MABEZ number that starts with 0901-07 costs 70 cents / call.
Accessibility from abroad
- Fixed line : In principle, only MABEZ numbers of the country in which the connection is connected can be reached from the fixed line.
- Mobile network : Only MABEZ numbers from the country of the home network can be reached from the mobile network, but not in the country in which the caller is registered via roaming . The reason for this is the so-called “Eurovision tourism”, which has been more popular since 1998, when a neighboring country was visited with one's own mobile phone in order to vote for one's own country in the Eurovision Song Contest . Not all roaming partners allow calls to the MABEZ numbers of the home network. The costs from abroad generally correspond to a call from the external network to a landline number in the home network, which are usually higher than the costs of the call to a MABEZ number from the home network.
- VoIP : Accessibility and costs for all numbers apply to VoIP providers worldwide.
abuse
As with all chargeable value-added numbers, there is always abuse with these numbers. Lure calls to mobile phones or landlines are intended to induce the caller to “call back” a MABEZ number. Internationally, MABEZ numbers are considered to be "non-dial-back". This means that transmission via telephone number transfer ( CLIP ) is not permitted. In such a case, both the Federal Network Agency and the technical service provider should be informed immediately.
