The T‑Mobile Polska network structure ensures efficient expansion and reconfiguration in order to adapt to new requirements related to the developments in the telecommunications market.
Exchanges (MSC/TSC) are the basic entities in the T‑Mobile Polska network. Based on their function, they can be divided into three categories:
- Standalone – MSC (direct handling of users, they do not carry any traffic between MSCs),
- Transit – TSC (they transit the telecommunications traffic, but they do not handle users),
- Combined – MSC (they both handle the users, and transit telecommunications traffic between different MSCs.)
The T‑Mobile Polska network consists of Transit Areas that overlap with the geographical area of Numbering Zones.
The number and location of the Points of Interconnection has an influence on the involved network elements, whose resources are used for establishing a connection. Therefore, based on the information on the network provided by the operator requesting telecommunication access, the actual number and location of the Points of Interconnection may be optimized.
Scope of cooperation within the service of termination of SMS in the T‑Mobile Polska Network
The scope of cooperation concerning the service of termination of SMS in the T‑Mobile Polska Network.
Rules of Cooperation of the Parties
1. T‑Mobile Polska shall not be liable for the content of SMS (Short Message Service) text messages terminated in the T‑Mobile Polska network. This also includes the use of alphanumeric representation.
2. Telecommunication traffic between the network of a Mobile Network Operator and the T‑Mobile Polska network related to the termination of an SMS is measured both by T‑Mobile Polska and the Mobile Network Operator.
T‑Mobile Polska and the Mobile Network Operator will cooperate on issues related to the SMSC numbers
and to ensure the compatibility of their Networks.
Technical information about cooperation with SMS termination in the T‑Mobile Polska Network
1. The SMS sending service is carried out according to standards 3GPP TS 23.040 and 3GPP TS 29.002 and others pointed out in these standards.
2. The SCCP protocol is used for transmitting SMS messages between the operators. This includes the termination of SMS services.
3. The exchange of signalling traffic used for SMS termination service is performed by bundle signalling lines dedicated for handling SCCP traffic, terminated at the following Points of Interconnection:
- 01-217 Warszawa, ul. Kolejowa 19/21
- 03-236 Warszawa, ul. Annopol 3
- 62-052 Komorniki, ul. Stanisława Nowaka 9 DZ 7461
4. It is required that at least 2 signalling link bundles connected to the Points of Interconnection specified in point 3 be set up and located in different cities
5. Rules of dimensioning and expansion of link bundles of the traffic related to the termination of the SMS service are similar to those for the bundles of SS7 links at the Points of Interconnection.
6. Only the traffic of SMS termination service and other SCCP traffic that T‑Mobile Polska agreed to carry can be exchanged through the link bundles at the Points of Interconnection. T‑Mobile Polska shall have the right to block traffic that is not associated with the SMS termination service, and that for which T‑Mobile Polska has not agreed to transmit.
1. The basis for billing is the number of text messages terminated in the T‑Mobile Polska network – sent from the SMSC of the Mobile Network Operator and delivered through the Points of Interconnection to the T‑Mobile Polska network end users.
2. For verification purposes, the Mobile Network Operator and T‑Mobile Polska will record at least:
- the time and date of sending the SMS message
- sender number
- recipient number
- SMSC number from which the SMS message was transmitted.
3. A message is considered delivered to the T‑Mobile Polska Network when the T‑Mobile Polska SMSC forwards it to the SMSC of the Mobile Network Operator and the latter SMSC acknowledges the reception of the message.
